Description

Lock core structure of cylinder lock

The utility model belongs to a kind of lock head device of various cylinder lock sets.

At present, the various cylinder lock sets of using, the lock head structure of its unlatching is to be made of parts such as lock body, lock core, upper and lower pellet shot from a slingshot, springs, i.e. lock core in the lock body, effect by key, make each the corresponding pellet shot from a slingshot of going up that is provided with in each time pellet shot from a slingshot that is provided with in its lock core and the lock body,, in fixing hole, slide by the elastic force of spring, make its lockset lock close and open, play the lock pin effect of lockset.This kind structure is opens different locks with different keys, and for more current unified management service departments, as hotel, hotel etc., all mixes because of key more and bring many troubles to work service.

The purpose of this utility model is that all kinds of cylinder lock sets are designed a kind of available two or many lock head structures that the key of dissimilar tooth form is opened same lock, making it can be that supporting key is that independent user opens use with the one handle, can be again that unified services person opens for one group of lock of a plurality of independent users with a key in its other several handles, be convenient to Service Management, increase work efficiency.

Its technology contents of the utility model is realized by following technical scheme: its structure is by pellet shot from a slingshot, middle pellet shot from a slingshot under lock body, lock core and three to six groups, goes up parts such as pellet shot from a slingshot, spring and constitute.Each time pellet shot from a slingshot, middle pellet shot from a slingshot, last pellet shot from a slingshot and spring are positioned at each corresponding hole that lock core and lock body are provided with respectively successively.Each time pellet shot from a slingshot and its length of middle pellet shot from a slingshot are to determine according to the tooth depth of key, its length of pellet shot from a slingshot is to determine according to the length of following pellet shot from a slingshot and middle pellet shot from a slingshot on each, the middle pellet shot from a slingshot of each group is determined its number according to the number and the tooth depth of key, and establishing of promptly having is one or more, and what have can not establish.

Fig. 2: the utility model with special-purpose assorted key operated one the lock work shape generalized section,

Fig. 3: (lock head structure with available two keys is an example to the utility model with the section shape schematic diagram of key operated work that can open many locks, promptly following pellet shot from a slingshot, middle pellet shot from a slingshot, in several groups of combinations of pellet shot from a slingshot and spring, the middle pellet shot from a slingshot of setting is one a lock head structure).

Narrate structure content of the present utility model and work using method in conjunction with the accompanying drawings below by embodiment:

Structure content: referring to Fig. 1, the utility model is by pellet shot from a slingshot (3), middle pellet shot from a slingshot (4) under lock body (1), lock core (2) and three to six groups, goes up pellet shot from a slingshot (5), formation such as spring (6) part of etc.ing, lock core (2) is fitted in the medium position of lock body (1), be provided with corresponding three to six holes that are arranged in parallel in lock body (1) and the lock core (2), pellet shot from a slingshot (3), middle pellet shot from a slingshot (4) under in each hole, placing successively, go up pellet shot from a slingshot (5) and spring (6) from lock core (2) to lock body (1).Each time pellet shot from a slingshot (3) and middle pellet shot from a slingshot (4) can be determined its length according to the height of the profile of tooth of adapted key, and the length of pellet shot from a slingshot on each (5) is determined according to the length of pellet shot from a slingshot (3) and middle pellet shot from a slingshot (4) down.At the following pellet shot from a slingshot (3) of each group, middle pellet shot from a slingshot (4), go up in pellet shot from a slingshot (5) and spring (6) combination, number of pellet shot from a slingshot (4) is that number and tooth depth by key decides in the middle of it, can be if do not establish.For in each group of pellet shot from a slingshot (4) in the middle of being provided with or several groups, can establish one or more, promptly same lock established one in the middle of the lock head structure of pellet shot from a slingshot (4) can be with two key operated, the lock head structure of establishing two middle pellets shot from a slingshot (4) can be with three key operated.

Using method (is example with one deck room, hotel): 1, for independent user, during use with its special-purpose assorted key operated getting final product.Promptly when key inserts lock core (2) (shown in Figure 2), the key crown is oppressed each pellet shot from a slingshot, and pellet shot from a slingshot (3) is filled and led up to lock core (2) periphery, and this moment, rotational lock core (2) can be opened lockset.2, for unified services person, during use, directly is each tenant and work management service with its another shared key by waiter, when being key insertion lock core (2) (shown in Figure 3), the key crown is oppressed each pellet shot from a slingshot, pellet shot from a slingshot (3) (one or more) and middle pellet shot from a slingshot (4) are filled and led up to lock core (2) periphery, and this moment, rotational lock core (2) can be opened lockset.

The utility model modern design, rational in infrastructure.Use the supporting various locksets of the utility model, manipulate simply, carrying out work service for unified management provides convenience, has reduced trouble

Claims (2)
