Abstract
The invention provides a male lock cylinder with adjustable length. A lock sleeve is screwed on the outer wall of a lock shell in a threaded connection way, a length positioning pin and a spring are arranged in a pin hole of the lock shell, a strip-shaped positioning pin lock hole is formed in the lock sleeve, and the outer end of the length positioning pin is sprung and clamped in the positioning pin lock hole under the action of the spring. Thus, the length of the lock cylinder can be adjusted by screwing the lock sleeve by pressing the length positioning pin into the lock shell, so that the adjustment of the length of the lock cylinder is very simple. In addition, because the real lock cylinder is hidden in the lock sleeve, even if a lawbreaker damages the lock sleeve by violence, the lock cylinder can not be unlocked, thereby playing a good anti-theft role. Meanwhile, the length of the lock cylinder in any trough type or internal structure can be adjusted by the structure that the spring and the length positioning pin are installed in the lock shell and the strip-shaped pin hole is formed in the lock sleeve. Therefore, the lock cylinder provided by the invention is more reasonable in structure, simple and convenient in length adjustment, and wide in applicability.
Description
Technical field
The present invention relates to a kind of structure of lock core.
Background technology
The outer tooth lock that lengthens in the market mostly is regulates length by the lengthening chip module installing different length additional on the basis of a regular length lock core, adopt words in this way, first lengthen chip module to be made up of several part, requirement on machining accuracy be higher, assembling also pretty troublesome (if add lengthy motion picture and tapered end to just will not cause lock core rotate tight, have some setbacks); Secondly because often kind add lengthy motion picture can only a corresponding length; therefore usually can join with a lock core the complete sale of form that multiple specification adds lengthy motion picture; once lock core employs one of them suitable add lengthy motion picture after, remaining adds lengthy motion picture and is just difficult to be used to again, thus can cause waste.Therefore, the invention is intended to adopt a kind of adjustment length wise newly to avoid these problems.
Summary of the invention
The object of the invention is to be to overcome the deficiencies in the prior art, provide a kind of more reasonable structure, lock core length adjustment simple and convenient, and the length-adjustable outer tooth lock core that applicability is wide.
In order to solve the technical problem of above-mentioned existence, the present invention adopts following technical proposals:
A kind of length-adjustable outer tooth lock core, include lock housing, lock gall, the some groups of hoodle assemblies be located in lock housing and lock gall, described lock housing outer wall is threaded connection mode and is screwed with lock tube, by interior spring length alignment pin being housed outward successively and make length alignment pin reset outward in the pin hole of described lock housing; Described lock tube has the alignment pin lockhole of bar shaped, and under described spring action, the outer end of length alignment pin is ejected and is stuck in this alignment pin lockhole.
In the improvement project to above-mentioned length-adjustable outer tooth lock core, described length location 5 is in " convex " font.
Compared with prior art, the invention has the beneficial effects as follows: be screwed with lock tube owing to being threaded connection mode on lock housing outer wall, again in the pin hole of described lock housing by interior spring length alignment pin being housed outward successively and make length alignment pin reset outward, and on described lock tube, have the alignment pin lockhole of bar shaped, under described spring action, the outer end of length alignment pin is ejected and is stuck in this alignment pin lockhole, just can turn lock tube have adjusted as long as length alignment pin is pushed in lock housing when adjusting lock core length like this, make the length adjustment of lock core very simple, and can arbitrarily regulate length thick to adapt to different doors in certain scope, in addition, because real lock core is ensconced in lock tube, even if lawless person adopts violence, mode destroys lock tube, still cannot opening lock master, thus plays good anti-theft function, meanwhile, it is no matter the lock core of what grooved or internal construction, can adopt and be arranged on spring in lock housing and length alignment pin and open the such structure of bar shaped pin hole on lock tube to regulate lock core length, therefore, the adjustment of more reasonable structure of the present invention, lock core length is simple and convenient, and applicability is wide.
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail:
[accompanying drawing explanation]
Fig. 1 is the schematic perspective view (after inserting key) of the embodiment of the present invention;
Fig. 2 is the structural representation of the embodiment of the present invention;
Fig. 3 is the assembling schematic diagram of the embodiment of the present invention.
[detailed description of the invention]
The present invention is a kind of length-adjustable outer tooth lock core, as shown in Figures 1 to 3, include lock housing 1, lock gall 2, the some groups of hoodle assemblies 3 be located in lock housing 1 and lock gall 2, at this, described lock housing 1 outer wall is threaded connection mode and is screwed with lock tube 4, by the interior spring 6 length alignment pin 5 being housed outward successively and making length alignment pin 5 reset outward in the pin hole 11 of described lock housing 1, described lock tube 4 has the alignment pin lockhole 41 of bar shaped, under described spring 6 acts on, the outer end of length alignment pin 5 is ejected and is stuck in this alignment pin lockhole 41, like this when installing room lock, when user needs to adjust lock core length according to the thickness of oneself door, with aids such as screwdrivers, length alignment pin 5 is interior by when making it to hide in pin hole 11 toward the pin hole 11 of lock housing 1, just can turn lock housing to adjust lock housing, distance between two outer ends of lock housing, often turn a circle, length alignment pin 5 under the action of the spring its outer end all can ejecting card in alignment pin lockhole 41, if now the length of lock core is also improper, then again with aid, length alignment pin 5 is again rotated lock tube by making it to hide in pin hole 11 in the pin hole 11 of lock housing 1, until lock housing, when lock tube is just clamped inside and outside door, namely the adjustment of lock core length is completed.
As can be seen from above, the length adjustment of lock core is very simple, and can arbitrarily regulate length thick to adapt to different doors in certain scope; In addition, because real lock core is ensconced in lock tube, even if lawless person adopts violence, mode destroys lock tube, still cannot opening lock master, thus plays good anti-theft function; Meanwhile, it is no matter the lock core of what grooved or internal construction, can adopt and be arranged on spring in lock housing and length alignment pin 5 and open the such structure of bar shaped pin hole 11 on lock tube to regulate lock core length, therefore, the adjustment of more reasonable structure of the present invention, lock core length is simple and convenient, and applicability is wide.
When enclosing for avoiding the many turns of lock tube one, the long or few turn one of the length of lock core is enclosed and the length of lock core can be caused too short, usually establishes thinner by the thread of lock housing and lock tube.
Preferably, as shown in Figure 3, described length alignment pin 5 is in " convex " font.
Usually, the pin hole 11 of lock housing 1 is blind hole, and certainly, it also can be through hole, but now, through hole is segmented, and the aperture in outside is large, and the aperture of the inside is little, drops in lock housing to play positioning lock is resetted outward to avoid spring.
Although reference above embodiment describes the present invention in detail, but be it will be apparent to one skilled in the art that by the disclosure, and when not departing from principle of the present invention and the scope of described claim restriction, can make a variety of changes the present invention or revise.Therefore, the detailed description of disclosure embodiment is only used for explaining, instead of is used for limiting the present invention, but is defined by the subject-matter of the claims the scope of protection.
