Description
One, technical field:
The present invention relates to a kind of magnetic holding device, particularly relate to a kind of magnetic-holding controller.
Two, background technology:
Magnetic-holding electric magnet commonly used at present has following two kinds: the one, and "on" position keeps electromagnet, this class electromagnet is divided into two kinds again, a kind of is that energising release state keeps, another kind is to keep operate condition, must switch on always, the electromagnet of this hold mode is big with electrical power consumed, the easy heating burnout of coil, use cost height.The 2nd, machine performance keeps electromagnet, this class electromagnet is the motion state that keeps electromagnet by mechanical structure, whole electromagnet is made up of two groups of electromagnet, a part is the action part of electromagnet, another part is mechanical retaining part, two groups of electromagnet respectively have coil and magnetic structure, and this electromagnet structure more complicated, cost height, volume is big, failure rate is high.
In addition, raising along with development of technology and economic level, people more and more use the lockset of multiple anti-theft feature, the lockset that has multiple anti-theft feature at present all has blocking mechanism, this blocking mechanism uses magnetic-holding electric magnet usually, and this electron-like lock its secret theftproof performance is in principle compared raising greatly with traditional spring lock.But also there are some problems in actual operating position: big with electrical power consumed, and the easy heating burnout of coil, the coil cost is also higher.
Three, summary of the invention:
The objective of the invention is: overcome the deficiencies in the prior art, a kind of reasonable in design, simple in structure, cost is low, failure rate is low and wasted work is little magnetic-holding controller is provided.
Technical scheme of the present invention is: a kind of magnetic-holding controller, contain moving iron core, permanent magnet, spring, solenoid and support, described support front end is fixed with a non-magnetic conductive board of annular, a disc magnetic conductive board is fixed in its rear end, fix a coil rack on the described support, suit is fixed a non-magnetic conduction sleeve pipe in the inner chamber of described coil rack, be fixed with solenoid in its outside annular groove, the two ends of described solenoid are connected with the both positive and negative polarity of DC power supply respectively, be set with moving iron core from front to back successively in the described non-magnetic conduction sleeve pipe, spring, every magnet and permanent magnet, described moving iron core is the step cylinder, and the thin footpath of its front end cylinder passes from the interior annular distance of described non-magnetic conductive board.
Described moving iron core rear end is provided with thin footpath cylinder, and the front end sleeve of described spring is contained on this thin footpath cylinder.Perhaps described moving iron core rear end is provided with blind cylindrical hole, and the front end sleeve of described spring is contained in this blind cylindrical hole.Perhaps described front end every magnet is provided with thin footpath cylinder, and the rear end of described spring is sleeved on this thin footpath cylinder.Perhaps described front end every magnet is provided with blind cylindrical hole, and the rear end of described spring is sleeved in the blind cylindrical hole.
Described non-magnetic conductive board and magnetic conductive board are fixed on the both ends of the surface of support by rivet respectively.The thin footpath of the moving iron core front end cylinder that stretches out non-magnetic conductive board is provided with jump ring, to limit the length of the moving non-magnetic conduction sleeve pipe of iron core indentation; Described non-magnetic conductive board is copper coin or aluminium sheet or non-metal board, and described magnetic conductive board is an iron plate; Described non-magnetic conduction sleeve pipe is copper pipe or aluminium or non metallic conduit.
The invention has the beneficial effects as follows:
1, failure rate of the present invention is low and energy consumption is little, during correct key unlocking, and the solenoid no power, moving iron core is held by permanent magnet, and is not overhanging; During non-correct key unlocking, the solenoid energising, moving iron core is overhanging, stop that lock core opens, play the effect of anti-pirate of the open, because solenoid often is in the no power state, thereby energy consumption is lower, and be not prone to accidents such as stuck, in addition, owing to existence every magnet, only need very little solenoid current, just can produce enough magnetic force, iron core be ejected, therefore, its energy consumption is lower, energy-saving effect is better, can prolong the useful life of lockset battery greatly, reduces the replacing frequency of lockset battery.
2, the present invention is reasonable in design, simple in structure, moving iron core sleeve is contained in the copper pipe, because copper pipe has high resistance to wear, thereby, prolong the useful life of moving iron core and copper pipe greatly, be difficult for being worn, in addition, copper pipe is the lower coefficient of friction of tool again, thereby, reduce the frictional force between moving iron core and the copper pipe greatly, improved the flexible sensitivity of moving iron core accordingly, improved anti-pirate of the open effect.
3, copper sheet of the present invention and iron plate are fixed on the both ends of the surface of support by rivet respectively, are convenient to installation and removal like this, reduce and use and maintenance cost.
4, the present invention is applied widely, in industrial or agricultural such as electronics, electric power, five metals lock industry, illumination, valve, automatic assembly line, has important purposes widely, particularly be applicable to the antitheft opening mechanism of advanced electronic anti-theft lock, have good economic benefit after the popularization.
Four, description of drawings:
Fig. 1 is the structural representation of magnetic-holding controller;
Fig. 2 is an A-A cutaway view shown in Figure 1.
Five, embodiment:
Embodiment one: referring to Fig. 1 and Fig. 2, among the figure, support 4 front ends of magnetic-holding controller are fixed with a non-magnetic conductive board 3 of annular by rivet 12, a disc magnetic conductive board 11 is fixed by rivet 12 in its rear end, fix a coil rack 9 on the support 4, suit is fixed a non-magnetic conduction sleeve pipe 8 in the inner chamber of coil rack 9, be fixed with solenoid 7 in its outside annular groove, the two ends of solenoid 7 are connected with the both positive and negative polarity of DC power supply respectively, be set with moving iron core 1 in the non-magnetic conduction sleeve pipe 8 from front to back successively, spring 10, every magnet 5 and permanent magnet 6, moving iron core 1 is the step cylinder, the thin footpath of its front end cylinder passes from the interior annular distance of non-magnetic conductive board 3, and should be provided with jump ring 2 by thin footpath cylinder, to limit the length of the moving non-magnetic conduction sleeve pipe 6 of iron core 1 indentation.Moving iron core 1 rear end is provided with thin footpath cylinder, and spring 10 is sleeved on this cylindrical front end in thin footpath.
