Description
Technical field
The utility model relates to a kind of five metals apparatus, and what be specifically related to is a kind of mains switch with lock.
Background technology
Power supply lock briefly is on mains switch, to add a lock, is in order to eliminate instrument or equipment unauthorized Switching Power Supply in running, to the hidden danger that safety is brought, to lock so claim mains switch again, and it can be widely used on elevator and other instruments.In general, for simple elevator or instrument,, be enough to control while adopt the mode of switching on and cutting off the power supply.At present, while the power supply that cuts off the power supply for switching on lock consists essentially of lock core, middle lock shell and outer lock shell; Wherein lock core and middle lock shell mate, and middle lock shell places outer lock shell, on outer lock shell, is provided with at least one pair of conductive feet; Have chute on the lock shell simultaneously, and poke rod is fixed on the lock core, poke rod passes chute; A conducting block is installed on poke rod, is worked as rotational lock core, conducting block is with after the pair of conductive pin contacts; Make it be in conducting state, the other pair of conductive pin that is installed in outer lock shell then is in off-state.The power supply lock of this structure when poke rod rotates, after conductive feet contacts, is located not accurate enough; Particularly in the conducting block sliding process, can conductive feet be pushed, after the conductive feet distortion; Just can't be in conducting state, therefore, its stability and reliability are not high enough.When placing lock core in the lock shell simultaneously, move axially, also several rivets need be set, make troubles to processing technology in the end of middle lock shell in order to prevent lock core.
Summary of the invention
In view of the deficiency that background technology exists, the technical problem that the utility model will solve provides a kind of accurate positioning, the ultrathin power supply lock that stability and reliability are high.
For this reason, the utility model adopts following technical scheme to realize: a kind of ultrathin power supply lock comprises lock core, middle lock shell and outer lock shell; The lock shell places said outer lock shell in said, and said outer lock shell is provided with at least one pair of conductive feet, said lock core and said middle lock shell coupling; The lock shell places said outer lock shell in said, is fixed with poke rod on the said lock core, and the circumference of said middle lock shell is provided with radial groove; Said poke rod passes said chute, it is characterized in that said poke rod is a ducted body, is provided with spring in said ducted body; And bead being set in the end of poke rod, said bead contacts with the inwall of said outer lock shell.
The end of said lock core is provided with circumferential groove, on said circumferential groove, is furnished with elastic ring, and the external diameter of said elastic ring is greater than the internal diameter of lock shell in said.
Said conductive feet is provided with two pairs, and the installation site of two pairs of conductive feet is corresponding with two ends of said chute, and its radian of chute that radially is provided with on the said middle lock shell is 90 degree.
Said conductive feet is half thick bamboo tube shape, and after pair of conductive pin flat raft was provided with, the cambered surface at its back side constituted flaring tank.
This structure of the utility model, when lock core rotated, the bead that drives on the poke rod rotated; Make bead contact with the pair of conductive pin, its accurate positioning is reliable, and stability is high; Simultaneously, when lock core and the assembling of middle lock shell, as long as adopt elastic ring to be stuck in the circumferential groove of lock core; Its assembling is simple and convenient, and the proterties of conductive feet more can improve the positioning function of bead.
Description of drawings
Combine accompanying drawing to further describe the relevant details of the utility model below again.
Fig. 1 is the overall structure figure of the utility model;
Fig. 2 is the STRUCTURE DECOMPOSITION figure of the utility model;
Fig. 3 is another structure chart that conductive feet is broken off of the utility model pair of conductive pin conducting;
Fig. 4 all is in the structure chart of off-state for two pairs of conductive feet of the utility model.
Embodiment
With reference to accompanying drawing, this ultrathin power supply lock comprises lock core 4, middle lock shell 12 and outer lock shell 2; Lock shell 12 places said outer lock shell 2 in said, wherein be symmetrically arranged with two row's pellets shot from a slingshot 9 on the lock core 4, and pellet shot from a slingshot 9 all is equipped with lock core spring 10; After the key 1 of coupling inserts, move pellet shot from a slingshot 9, compression lock core spring 10; Make that the end face of pellet shot from a slingshot 9 is concordant with the periphery of lock core 4, rotational lock core 4 just can be unblanked; These structures are known technology, repeat no more.Said outer lock shell 2 is provided with two pairs of conductive feet 8, and external lock, and 2 outer wall has screw thread, adopts nut 3 and screw thread coupling; Be convenient on the installation panel of the equipment that is installed in, said lock core 4 and said middle lock shell 12 couplings, said middle lock shell 12 places said outer lock shell 2; Be fixed with poke rod 5 on the said lock core 4, the installation site that the said middle circumference of locking shell 12 is provided with 11, two pairs of conductive feet 8 of radial groove is corresponding with two ends of said chute 11;, radial groove 11 its radians that are provided with on the said middle lock shell 12 are 90 degree, said poke rod 5 passes said chute 11; Therefore, the maximum rotation scope of its lock core 4 has only 90 degree, and poke rod 5 maximum slewing areas also are 90 degree simultaneously; Said poke rod 5 is a ducted body 14, in said ducted body 14, is provided with spring 6, and in the end of poke rod 5 bead 7 is set; After on the poke rod 5 that bead 7 is provided with, have 1/3rd to expose poke rod 5, remainder places in the ducted body 14; And contact with described spring 6, place middle lock shell 12 in the outer lock shell 2 after, its bead 7 just contacts with the inwall of said outer lock shell 2.Said conductive feet 8 is half thick bamboo tube shape, and after pair of conductive pin 8 flat rafts were provided with, the cambered surface at its back side constituted flaring tank.Insert key 1, behind the rotational lock core 4, drive poke rod 5 and rotate, make bead 7 on the poke rod 5 along the interior move of outer lock shell 2; After poke rod 5 rotate in place, the bead 7 on it just rolled in the tubaeform tank of pair of conductive pin 8 formation, under the elastic force effect of spring 6, pair of conductive pin 8 was connected; Make it be in stable conduction state, another then is in off-position to conductive feet, when counter-rotating lock core 4; During the other end of poke rod 5 no show chutes 11, two pairs of conductive feet 8 all are in the fault block state, after poke rod 5 arrives the other ends; Likewise, bead 7 rolls in this tubaeform tank to conductive feet 8 formation, makes it be in conducting state.The utility model this adopts bead 7 to roll and conductive feet 8 carried out conducting or disconnection, its accurate positioning; Stability and reliability are very high; Thereby can effectively control opening or closing of power supply, be used for instrument control or elevator, to guarantee the safe operation of instrument or elevator.
The end of said lock core 4 is provided with circumferential groove 15, on said circumferential groove 15, is furnished with elastic ring 13, and the external diameter of said elastic ring 13 is greater than the internal diameter of lock shell 12 in said.This structure, in lock core 4 is assemblied in the lock shell 12 after, employing elastic ring 13 blocks the circumferential groove 15 of lock core 4; And the external diameter of elastic ring 13 is greater than the internal diameter of middle lock shell 12, and therefore, lock core 4 just can not move axially; Can only rotate, its assembling is simple and convenient, and firmness is high.
In the utility model, the axial length with lock core 4, middle lock shell 12 and outer lock shell 2 designs enough shortly respectively, after three's assembling, just is called extremely thin switch lockset, therefore, is called ultrathin power supply lock.
