Abstract
Provided is a magnetron typed anti-touch safety switch which comprises a shell body and a unidirectional elastic resetting typed button switch which is arranged in the shell body. The utility model is characterized in that a moveable magnet which can act perpendicularly on the button of the unidirectional elastic resetting typed button switch is arranged in the shell body. Also, a fixed magnet which can be arranged on a moveable door and corresponds to the moveable magnet in the shell body is arranged in the shell body. The magnetic poles of the moveable magnet are contrary to that of the fixed magnet. The magnetron typed anti-touch safety switch of the utility model is characterized by a scientific design, a simple and reasonable structure. Through the simple principle that opposite poles of the magnet repel each other and the characteristics that the magnetic force is penetrating, the control on the unidirectional elastic resetting typed connection and disconnection device is realized. The utility model avoids unsafe elements in prior art which can lead power outwards because of contact with hard and tiny matters, hides the safety switch which used to be exposed outside inside the device thus obtaining a beautifying effect.
Description
Technical field
The utility model relates to safety switch, particularly a kind of magnet controlled touch-proof safety switch.
Background technology
At present, many family expenses or office electrical equipment all need carry out under powering-off state when operation or cleaning internal work zone.Because all there is certain danger the working region of this electric appliances under charged situation.For this reason, this electric appliances all can be installed auto-power-off device to guarantee safe handling.Such as: the shredder that office is used always just is provided with auto-power-off device, is in off-position when shredder just requires complete machine when opening the paper scrap storing barrel.The auto-power-off device that shredder generally adopts on the market is unidirectional elastic reset formula push-button switch, on the door of shredder paper scrap storing barrel or pull bucket, install one and protrude conducting or the disconnection that fulcrum directly touches unidirectional elastic reset formula push-button switch realization power supply, that is: when door open or during the extraction of pull bucket unidirectional elastic reset formula push-button switch utilize self elastic reset to make machine be in off-position.Though this mode can play the effect of cutting off the electricity supply automatically; but its weak point is the button contact of existing safety switch is exposed to the outside; the operator touches the button contact probably in the process of cleaning shredder paper scrap bucket; cause the conducting of shredder power supply; thereby lost the protective effect of safety switch, caused unnecessary security incident.The protrusion fulcrum that is exposed in addition on the outer safety switch also can influence the outward appearance or the human body of damaging.
The utility model content
The purpose of this utility model is to overcome the defective of prior art, and a kind of simple structure is provided, and reasonable in technology more can play the magnet controlled touch-proof safety switch of safety guarantee.
The magnet controlled touch-proof safety switch of the utility model comprises: housing and unidirectional elastic reset formula push-button switch in it is installed is characterized in that: be provided with a movable magnet that can vertically act on the button of unidirectional elastic reset formula push-button switch in the housing; Also comprise one can be installed on the dodge gate, with housing in the corresponding fixed magnet of movable magnet, the magnetic pole of described movable magnet is opposite with the magnetic pole of fixed magnet.
Be provided with a chute for the movable magnet slip in the described housing, movable magnet is installed in the chute, and movable magnet can endwisely slip in chute.
Described chute outside port is equipped with one and is used to the thin slice that prevents that movable magnet skids off in the chute.
Described thin slice is fixed on the housing of chute outside fracture.
The design principle of the magnet controlled touch-proof safety switch of the utility model is: utilize the opposite sex of the magnet character of repelling each other to produce the power that promotes internal magnet, thus the slip of control internal magnet.By thin slice being set, then can avoiding any object to be not intended to contact movable magnet or button fully and the situation of turn-on power takes place at chute outside port.
The magnet controlled touch-proof safety switch of the utility model, design science, simple and reasonable for structure, ingenious.The characteristic that principle of repelling each other with the simple magnet opposite sex and magnetic force have the effect of penetrating realizes the control to unidirectional elastic reset formula push-button switch.Avoided the existing safety switch may be, and will be exposed to safety switch outward again originally and can be hidden in the machine, reached effect attractive in appearance because the unsafe factor that causes power supply to be connected is suddenly bumped in false touch.
Description of drawings
Fig. 1 is the structural representation of magnet controlled touch-proof safety switch:
Fig. 2 is the supreme shell mechanism schematic diagram of magnet controlled touch-proof safety switch shown in Figure 1.
Fig. 3 is the decomposition texture schematic diagram of magnet controlled touch-proof safety switch shown in Figure 1;
Specific embodiments
Embodiment: can be clearly seen that from Fig. 1～Fig. 3 magnet controlled touch-proof safety switch comprises one by lower casing 3, goes up the housing that shell 4 is fastened and connected and forms, movable magnet 7, fixed magnet 8 and unidirectional elastic reset formula push-button switch 1.The merging position of lower casing 3 and last shell 4 is equipped with a chute 2 for movable magnet 7 slips by support 10, described unidirectional elastic reset formula push-button switch 1 is installed in housing lower casing 3, goes up 4 on shell, the movable magnet 7 vertical buttons 5 that are provided with in the chute 2 corresponding to unidirectional elastic reset formula push-button switch 1, be fixed with the thin slice 9 that can prevent that movable magnet 7 skids off in the chute 2 on chute 2 outside ports on the shell 4, chute 2 both sides of housing are respectively equipped with and are used for the hard-wired turnbuckle 6 of the utility model.
The using method of the magnet controlled touch-proof safety switch of the utility model and the course of work: the housing that will be provided with unidirectional elastic reset formula push-button switch 1 and movable magnet 7 by screw is fixedly mounted on the body of opening of device door inboard, installs and fixes magnet 8 at the correspondence position of opening door.When the unlatching door is closed, open in built-in movable magnet 7 processes of housing of fixed magnet 8 on close body on the door, the principle of utilizing the magnet opposite sex to repel each other, movable magnet 7 axial promotions in the chute 2 are vertically acted on the button 5 of unidirectional elastic reset formula push-button switch 1, button 5 is pressed down under the effect of movable magnet 7, make unidirectional elastic reset formula push-button switch 1 be in closure state, power turn-on.Otherwise when the unlatching door is opened, be fixed on the fixed magnet 8 opened on the door along with the unlatching of opening door away from movable magnet 7, the mutual expelling force of magnetic weakens thereupon and disappears, the button 5 of unidirectional elastic reset formula push-button switch 1 relies on its own elastic force and resets at this moment, unidirectional elastic reset formula push-button switch 1 promptly is in off-state, dump.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, its framework form can be flexible and changeable, can the subseries product.Just make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that the utility model is determined by claims of being submitted to.
