Abstract

The utility model relates to an anti-theft lock, which comprises a lock body (1) and a lock tongue box (2), wherein the lock body (1) is provided with an inclined main lock tongue (3); the side wall of the lock tongue box (2) is provided with a lock tongue hole corresponding to the main lock tongue (3); a reverse lock tongue (4) is arranged in the lock tongue box (2); and accordingly, the front side wall of the lock body (1) is provided with a reverse lock tongue hole. The anti-theft lock is characterized in that: a lever (5) which can rotate around a rotating pin is arranged in the lock body (1); one end of the lever (5) is inserted into a groove (8) of the main lock tongue (3), and the other end of the lever (5) is close to the reverse lock tongue hole on the front side wall of the lock body (1); and the bottom of the reverse lock tongue (4) is provided with a thrust spring (7). The anti-theft lock has the advantages of increasing the locking force and achieving an anti-theft reinforcement effect.

Description

A kind of theftproof lock
Technical field
The utility model relates to a kind of lockset, is specifically related to a kind of theftproof lock.
Background technology
China's utility model patent (patent No. is 200620111352.5) discloses a kind of improvement lock with tamper-resistant function; As shown in Figure 1; It comprises lock body 1 and dead bolt box 2, and oblique main dead bolt 3 is arranged on the lock body 1, and the dead bolt hole corresponding with main dead bolt 3 arranged on dead bolt box 2 sidewalls.It also is provided with reverse dead bolt 4 in dead bolt box 2 in addition, correspondingly on lock body 1 positive sidewall, has reverse dead bolt hole; The lever 5 that the pin that can rotate rotates is installed in the dead bolt box 2, and lever one end connects reverse dead bolt 4, and the other end is near dead bolt hole.When the main dead bolt 3 of lock body 1 puts in dead bolt box 2, withstand the end of lever 5 near dead bolt hole, the reverse dead bolt 4 that promotes lever 5 one ends stretches into the reverse dead bolt hole on the lock body 1 positive sidewall, constitutes two tongue structures.
But when opening the door, reset, on this lever 5 back-moving spring 6 must be installed in order to guarantee the reverse dead bolt 4 that is connected with lever.Because the active force of back-moving spring 6 directly puts on the main dead bolt 3 through the end near dead bolt hole, this is equivalent to the open the door power of direction of 3 one edges of main dead bolt, and at this moment stealer does not need the power of stirring of lockset in the past, opens main dead bolt 3 all the better easily; After main dead bolt 3 was released dead bolt hole, reverse dead bolt 4 also withdrawed from the reverse dead bolt hole of the positive sidewall of lock body automatically under back-moving spring 6 effects, and reverse dead bolt 4 does not have the function of reinforcing antitheft at all.
The utility model content
The utility model technical problem to be solved just provides a kind of theftproof lock that can increase coupling mechanism force.
The utility model technical problem to be solved is to realize through such technical scheme; It includes lock body and dead bolt box, and oblique main dead bolt is arranged on the lock body, and the dead bolt hole corresponding with main dead bolt arranged on the dead bolt box sidewall; Reverse dead bolt is housed in the dead bolt box; Correspondingly on the positive sidewall of lock body, have reverse dead bolt hole, it is characterized in that: be provided with the lever that the pin that can rotate rotates in the lock body, an end of lever injects in the groove of main dead bolt; The other end is near the reverse dead bolt hole on the positive sidewall of lock body, and thrust spring is equipped with in reverse dead bolt bottom.
Because lever is located in the lock body, the active force of thrust spring is directly delivered to the groove position of main dead bolt through reverse dead bolt and lever, has increased the coupling mechanism force of main dead bolt, simultaneously, has increased reverse dead bolt, has increased the function of reinforcing antitheft again.The utlity model has following advantage: increased coupling mechanism force, had the effect of the antitheft of reinforcing.
Description of drawings
The description of drawings of the utility model is following:
Fig. 1 is the structural representation of background technology;
Fig. 2 is the structural representation of the utility model;
Fig. 3 is the state diagram of the utility model locking.
Among the figure: 1. lock body; 2. dead bolt box; 3. main dead bolt; 4. reverse dead bolt; 5. lever; 6. back-moving spring; 7. thrust spring; 8. groove.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
As shown in Figure 2, the utility model includes lock body 1 and dead bolt box 2, and oblique main dead bolt 3 is arranged on the lock body 1; The dead bolt hole corresponding with main dead bolt 3 arranged on dead bolt box 2 sidewalls, reverse dead bolt 4 is housed in the dead bolt box 2, correspondingly on lock body 1 positive sidewall, have reverse dead bolt hole; It is characterized in that: be provided with the lever 5 that the pin that can rotate rotates in the lock body 1; One end of lever 5 injects in the groove 8 of main dead bolt 3, and the other end is near the reverse dead bolt hole on the lock body 1 positive sidewall, and thrust spring 7 is equipped with in reverse dead bolt 4 bottoms.
As shown in Figure 3, when locking a door, the main dead bolt 3 on the lock body 1 gets in the dead bolt box 2, and the active force of thrust spring 7 is directly delivered to groove 8 positions of main dead bolt 3 through reverse dead bolt 4 and lever 5, has increased the coupling mechanism force of main dead bolt 3.When opening the door, main dead bolt 3 is retracted into dead bolt box 2, and the groove 8 of main dead bolt 3 promotes lever 5 and rotates, and the other end of lever 5 ejects lock body 1 with reverse dead bolt 4, and this moment, door can be opened.
