Abstract
The utility model belongs to mechanical lock field, is a kind of novel anti-dial composite pellet lock core provided for the anti-technical opening weak effect of existing lock core.Comprise lock body, lock tube, lock gall and multiple composite pellet, composite pellet comprises female pellet and bullet, female pellet can lock tube activity relatively, there is in the lower end of female pellet first back-moving spring that female pellet is resetted, there is in the inside of female pellet the installing hole of bullet of installation bullet, bullet is placed in this installing hole, and can make bullet can relatively female pellet movable, and in the sub-installing hole of bullet, be provided with the second back-moving spring that bullet is resetted.Project organization compact and reasonable of the present utility model, precision is high, easy to install, adopts primary and secondary two pellet design that the technical opening difficulty of non-key is increased greatly, can more effectively prevent non-key key hard object switch primary and secondary pellet from unblanking.
Description
Technical field
The utility model belongs to mechanical lock field, particularly relates to a kind of antitheft composite pellet lock core.
Background technology
Existing anti-theft lock generally all only has one group of pellet, though its structure is simple, but its anti-technical opening weak effect, as long as use the hard object switch pellet of non-key can realize the object of unblanking.
Utility model content
The purpose of this utility model is a kind of novel anti-dial composite pellet lock core provided for the anti-technical opening weak effect of existing lock core.
The utility model is achieved by the following technical solution:
A kind of novel anti-dial composite pellet lock core, comprise lock body, lock tube, lock gall and multiple composite pellet, there is in lock body the cavity holding lock tube, lock tube is fixed in the cavity of lock body, there is the lock gall hole slot of an accommodation lock gall in lock tube, lock gall is contained in the lock gall hole slot of lock tube, there is a keyhole inserted for key in lock gall, there is a composite pellet installing hole be communicated with the keyhole of lock gall in lock tube, composite pellet is arranged in the composite pellet installing hole of lock tube, composite pellet comprises female pellet and bullet, female pellet can lock tube activity relatively, there is in the lower end of female pellet first back-moving spring that female pellet is resetted, there is in the inside of female pellet the installing hole of bullet of installation bullet, bullet is placed in this installing hole, and can make bullet can relatively female pellet movable, and in the sub-installing hole of bullet, be provided with the second back-moving spring that bullet is resetted.
Lock gall has a location pellet be mounted opposite with bullet, and location pellet is arranged in the location pellet installing hole on lock gall, has a location pellet back-moving spring that location pellet is resetted in the pellet installing hole of location.
The beneficial effects of the utility model: project organization compact and reasonable of the present utility model, precision is high, easy to install, adopt primary and secondary two pellet design that the technical opening difficulty of non-key is increased greatly, can more effectively prevent non-key key hard object switch primary and secondary pellet from unblanking.

Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further detail.
Embodiment
A kind of novel anti-dial composite pellet lock core as shown in Figure 1-Figure 3, it should be noted that, comprise lock body, lock tube 1, lock gall 2 and multiple composite pellet, there is in lock body the cavity holding lock tube, lock tube 1 is fixed in the cavity of lock body, there is the lock gall hole slot 3 of an accommodation lock gall 2 in lock tube 1, lock gall 2 is contained in the lock gall hole slot 3 of lock tube, there is a keyhole 4 inserted for key in lock gall 2, there is a composite pellet installing hole 5 be communicated with the keyhole of lock gall in lock tube 1, composite pellet is arranged in the composite pellet installing hole 5 of lock tube, composite pellet comprises female pellet 6 and bullet 7, female pellet 6 can lock tube 1 be movable relatively, there is in the lower end of female pellet 6 first back-moving spring 8 that female pellet 6 is resetted, there is in the inside of female pellet 6 the sub-installing hole 9 of bullet of installation bullet 7, bullet 7 is placed in this installing hole, and can make bullet can relatively female pellet movable, and in the sub-installing hole 9 of bullet, be provided with the second back-moving spring 10 that bullet 7 is resetted.Lock gall 2 has a location pellet 11 be mounted opposite with bullet 7, and location pellet 11 is arranged in the location pellet installing hole 12 on lock gall 2, in location pellet installing hole 12, have a location pellet back-moving spring 13 that location pellet 11 is resetted.
Primary and secondary lock locking state is as shown in Figure 1: now, tack pellet and outer tack pellet are ejected by spring, and simultaneously, flat nose subcard enters female pellet, and outer flat nose subcard enters lock gall and stops lock gall to rotate, and is in locking state.
Opening is as shown in Figure 2: insert key, when group pellet and female pellet aim at key tooth flower groove simultaneously, inside and outside tack pellet departs from lock gall simultaneously, is rotated further key, drives lock gall and the parts that are attached thereto to rotate, reaches the object of locking and being unlocked.
The advantage of this structure is, precision is better, and secrecy is higher, and the difficulty of anti-technical opening is larger, more advanced manufacturing process.When inserting plectrum mother pellet in lock gall keyhole by the hard object of non-key, be difficult to meet on the same line, same position have two kinds of extreme difference pellets and inside and outside tack pellet top is returned outside lock gall simultaneously.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, simple change and the replacement of those ordinary skill in the art are all within protection domain of the present utility model.
