Description
The utility model relates to a kind of lockset, particularly a kind of double pin-and-hole lock.
Our lockset of adopting at present mostly is the conventional lock of single pin-and-hole, and this lock not only has pin-and-hole on the lock core, and also be provided with pin-and-hole on the sleeve, therefore external form not attractive in appearance for this class lockset ubiquity, and security performance is general, and the not repetitive rate of lock is difficult to problems such as raising.Relevant by retrieval document finds no and the same or analogous record of the utility model.
The purpose of this utility model provides a kind of double pin-and-hole aesthetic in appearance, that security performance is good and locks.
Technical solution of the present utility model is:
Have double lock core pin-and-hole on the lock core, pin correspondingly is assemblied in the lock core pin-and-hole, has circlip groove vertically in the two side of lock core pin-and-hole, is mounted with the card key in the circlip groove, and pin is provided with pin-and-hole towards the one side of circlip groove.
Have radial direction through hole in the circlip groove.The inwall upper edge of sleeve is axially arranged with and the corresponding sleeve circlip groove of card key.A side that contacts with circlip groove on the card key is fixed with card key leg and spring.
The utility model novel structure compactness, with low cost, aesthetic in appearance, precision is higher, has the excellent safety energy.
Below in conjunction with accompanying drawing and most preferred embodiment content of the present utility model is further elaborated.
Fig. 1 is the structure assembling schematic diagram of double pin-and-hole lock.
With reference to accompanying drawing, the utility model comprises lock core 1, sleeve 2, lock core pin-and-hole 3, pin 4 and pin spring 10 etc.Have double lock core pin-and-hole 3 on the lock core 1, pin 4 correspondingly is assemblied in the lock core pin-and-hole 3, and the two side of pin core 1 has circlip groove 7 vertically, and card key 6 is placed in the circlip groove 7, and pin 4 is provided with pin-and-hole 5 towards the one side of circlip groove 7.Radially have through hole in the circlip groove 7, the distribution of through hole is corresponding one by one with pin-and-hole 5; A side that contacts with circlip groove 7 on card key 6 is fixed with card key leg 8 and spring 13.Pin 4 is provided with spring 10, and cotter way lid 11 lids are buckled on the lock core pin-and-hole 3, and pin 4 and pin spring 10 are assemblied in the lock core pin-and-hole 3.Outside lock core 1, be with sleeve 2, be axially arranged with in the inwall upper edge of sleeve 2 and card key 6 corresponding sleeve circlip grooves 9, on card key 6 and sleeve circlip groove 9, be equipped with can not self-locking the inclined-plane.
During use, double key 12 is inserted lockholes, all double pins 4 overcome the active force of pin spring 10, move up, and pin-and-hole 5 and the circlip groove 7 interior through holes on the pin 4 are communicated.Turn double key 12 this moment, because inclined-plane that can not self-locking on card key 6 and the sleeve circlip groove 9 interacts, make the 6 stressed radially contractions of card key, in the pin-and-hole 5 that card key leg 8 extend on the pin 4, make whole card key 6 enter circlip groove 7 the insides, 2 realizations of lock core 1 and sleeve relatively rotate, and lock is opened.After lock was opened, key was extracted out, under the effect of pin spring 10 and spring 12, and pin 4 and card key 6 homings.
