Description
Technical field
This utility model relates to Medical treatment and nursing safety guard technology field, especially a kind of Medical restraining belt magnetic control lock.
Background technology
Existing magnetic control lock is round plastic lock, including lock body and dead bolt, described lock body is bonded by glue by lock and locking closure, sponge it is provided with in lock, the inner top surface of locking closure is provided with two pyrometric cones, described lock and locking closure define an accommodation space jointly, two half-round metal locking plates it are additionally provided with in this accommodation space, it is respectively equipped with the groove suitable with said two pyrometric cone on this two halves circle metal latch sheet, the outer end of described dead bolt has a base, the inner lock that passes matches with described two halves circle metal latch sheet, it is respectively equipped with arc notch in the middle part of described two halves circle metal latch limit, the outer circumference surface of described dead bolt the inner is provided with the annular groove coordinated with arc notch para-position；The magnetic control lock of said structure design is during routine use, owing to pyrometric cone coordinates half-round metal locking plate with the form on single-point concavo-convex phase top, and sponge expansion force is the most powerful that lasting support force can not be provided to cause half-round metal locking plate position to offset, half-round metal locking plate can not reset in time and block dead bolt and make magnetic control lock lose its basic function；Secondly lock and the locking closure of magnetic control lock is bonded by glue, making lock and locking closure separate in glue bonding place in the case of the extruding by some strength external force to depart from, additionally sponge is susceptible in use for some time to aoxidize and rots to cause service life of magnetic control lock the longest.
Therefore, prior art needs to be improved and improves.
Summary of the invention
In place of the deficiencies in the prior art, it is smooth that the purpose of this utility model is to provide a kind of locking plate activity, it is possible to the most fixing and unblock, the Medical restraining belt magnetic control lock of length in service life.
For achieving the above object, this utility model be the technical scheme is that
A kind of Medical restraining belt magnetic control lock, including shell, lock core and dead bolt, lock core is arranged in shell, lock core includes locking the end and locking closure, the lock end, is provided with two support columns with screwed hole, locking closure is provided with the screw mounting hole corresponding to support column, and screw is locked screwed hole through screw mounting hole and locking closure and the lock end is fixed together；Being additionally provided with two locking plates symmetrical about two support column axial connecting lines and four limited posts at the bottom of described lock and between locking closure, locking plate is provided with the stopper slot matched with limited post；It is provided with spring between outer end and the lock hole, location, the end of those locking plates；The outer end of described dead bolt has a base, and matching with described two locking plates in the inner lock end that passes, is respectively equipped with arc notch in the middle part of described two lock seamings, and the outer circumference surface of described dead bolt the inner is provided with the annular groove coordinated with arc notch para-position.
Further, the distance between described limited post and shell is less than the diameter of spring.
Further, described shell, lock core and dead bolt are all made of metal.
Further, the through hole inner corresponding to locking plate it is provided with at the bottom of described lock.
Compared with prior art, the beneficial effects of the utility model are: owing to using above-mentioned structure design, locking plate is fixed by support column and limited post, ensure that locking plate all keeps a movement locus in upper and lower moving process, simultaneously using the elastic force of spring as the power of the upper and lower folding of locking plate when unblanking, ensure that locking plate will not offset easily, substantially increase its service life.
