Abstract

The utility model discloses an accurate stop gear of lock core, including taking the lock core and the stop gear in key hole, its characterized in that is equipped with the recess at the lock core tail end, in the recess is run through from the head end of lock core in the key hole, be equipped with the boss on stop gear, connect through recess, the boss of mutually supporting between lock core and the stop gear, and the tail end that the key hole was just in time sealed to the boss is with the degree of depth of key restriction in the settlement. In the carrier roller device, stop gear realizes effectively not only that the key accuracy is spacing, as lock core inner bag extension drive mechanism's solution, can abandon solitary key spacer pin, two mechanisms of transmission connecting rod completely simultaneously, closes both functions no. 2 into one, reduces the structure complexity and the production degree of difficulty, effectively practices thrift the cost, improves production efficiency, reduces the lock core fault rate.

Description

A kind of lock core accurate limiting mechanism

Technical field

The utility model relates to lock technology field, particularly relates to a kind of lock core accurate limiting mechanism.

Background technology

Lockset has referred to the utensil of sealing process, is extensively present in daily life; The lock core of prior art, normally accurately stir hoodle in lock core or blade to tram by key tooth flower and open lockset, for making key tooth flower correctly mate with the hoodle in lock core or blade, when key just must be made to insert, be limited in the correct degree of depth.The spacing technology one of existing key is by arranging spacer pin at lock core afterbody, this kind of technical pattern complexity, process loaded down with trivial details; Another spacing technology is the shoulder limited inserting depth by key, and its major defect is the standardized production being difficult to realize different size cover lock core, and can increase the waste of key materials.

On the other hand, lock core is in order to adapt to different installation environments and the different length of needs, and prior art additionally increases a bindiny mechanism at the afterbody of standardization lock core, extends to required length.Its defect is that the T connector of lock core afterbody takes up room greatly, causes that bindiny mechanism's intensity is too weak easily to be twisted off by brute force.

Summary of the invention

For the defect existed in prior art, the purpose of this utility model be to provide a kind of structure simple, easy to connect, integrate key positioner and the lock core accurate limiting mechanism of the function that is in transmission connection.

For reaching above object, the utility model adopts following technical scheme.

A kind of lock core accurate limiting mechanism, comprise lock core and the position-limit mechanism of band keyhole, it is characterized in that, be provided with groove at lock core tail end, described keyhole extends through in groove from the head end of lock core; Position-limit mechanism is provided with boss, is connected by the groove that cooperatively interacts, boss between lock core and position-limit mechanism, and key is limited in the degree of depth of setting by the tail end that boss just in time seals keyhole.

Further illustrating as such scheme, described boss is arranged on one end of position-limit mechanism, is provided with drive link connector at the other end of position-limit mechanism.

Further illustrating as such scheme, position-limit mechanism is connected with at least one lock core extending mechanism.

Further illustrating as such scheme, the location swap of described boss and groove, is arranged on boss on lock core, is arranged on position-limit mechanism by groove.

Compared with prior art, the beneficial effects of the utility model are:

One, position-limit mechanism not only effectively realizes key accurate limiting, extend the solution of transmission mechanism as lock core inner bag simultaneously, independent key spacer pin, driving connecting rod Liang Ge mechanism can be abandoned completely, by both function two-in-one, reduce structure complexity and production difficulty, effectively cost-saving, enhance productivity, reduce lock core fault rate.

Two, owing to groove being located at lock core afterbody and for laterally, solving the strength problem of connecting portion, effectively reduce production difficulty, cost-saving, enhance productivity, reduce lock core fault rate.

Detailed description of the invention

For setting forth essence of the present utility model further, by reference to the accompanying drawings detailed description of the invention of the present utility model is described as follows.

As shown in Figure 1 and Figure 2, a kind of lock core accurate limiting mechanism, comprise lock core 1 and the position-limit mechanism 2 of band keyhole 1-1, it is characterized in that, be provided with groove 1-2 at lock core 1 tail end, described keyhole 1-1 extends through in groove 1-2 from the head end of lock core; Position-limit mechanism 2 is provided with boss 2-1, and groove 1-2, boss 2-1 by cooperatively interacting between lock core 1 and position-limit mechanism 2 connect, and key 3 is limited in the correct degree of depth by the tail end that boss 2-1 just in time seals keyhole 1-1, thus effectively avoid tartar to misplace.

Wherein, described boss 2-1 is arranged on one end of position-limit mechanism 2, is provided with drive link connector 2-2 at the other end of position-limit mechanism 2, is directly connected with driving member.In other embodiments, according to the different length of lock core 1, position-limit mechanism 2 is also connected with at least one lock core extending mechanism, and lock core 1 is connected with driving member after being extended with lock core extending mechanism by position-limit mechanism 2 again, to adapt to the requirement of the different lock core length of needs because installation environment is different.

Compare the spacing technology of existing key, the lock core accurate limiting mechanism that the present embodiment provides can abandon independent key spacer pin, driving connecting rod Liang Ge mechanism completely, by both function two-in-one, by structure and the simple position-limit mechanism of technique, realize the spacing object with extending inner bag connection for transmission mechanism of key simultaneously, owing to groove being located at lock core afterbody and for laterally, solve the strength problem of connecting portion, effective reduction production difficulty, cost-saving, enhance productivity, reduce lock core fault rate.

Above detailed description of the invention has been described in detail essence of the present utility model, but can not limit protection domain of the present utility model with this.Apparently, under the enlightenment of the utility model essence, the art those of ordinary skill also can carry out many improvement and modification, and such as, the location swap of boss and groove, is arranged on boss on lock core, is arranged on position-limit mechanism by groove.It should be noted that these improve and modify all to drop within claims of the present utility model.
