Detailed Description

The following describes the present invention in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, there is known a lock cylinder including a base 1, a moving member 2, and a cover 3, wherein the moving member 2 is movably disposed between the base 1 and the cover 3, and the cover 3 is disposed at an upper end of the base 1. In the in-service use process, thereby the lock core will realize mutually supporting with the lock nail that the lock is dead and then be used for fixing article between the two, therefore explain for better explanation to combine the explanation with the lock nail, but the lock nail is not the utility model discloses a necessary characteristic, just the utility model discloses a key is the lock core. The cap 3 is tapered so that the upper portion is smaller than the lower portion, and the inner space is also smaller than the lower portion. Therefore, the moving space of the moving member 2 is changed during the moving process.

Specifically, referring to fig. 2, it can be seen that the cover 3 is provided with a mounting hole 9, the moving member 2 is provided with a connecting hole 10, and the center of circle of the mounting hole 9 and the center of circle of the connecting hole 10 are located on the same straight line. Therefore, in the actual use process, the locking nail firstly passes through the fixed object and then sequentially passes through the mounting hole 9 and the connecting hole 10, so as to enter from the cover 3 to reach the moving part 2 and be locked.

And the cover 3 is provided with the arc groove 14 on the periphery of the mounting hole 9, so that the arrangement of the lock pin and the integral arrangement of the lock core are convenient, and the arc groove 14 can reduce the contact area, so that the arrangement is more stable.

The dead structure of concrete lock is like fig. 2, and it is known that a plurality of first mounting groove 7 has been seted up on moving member 2, and is provided with ball 8 in the first mounting groove 7, supports to lean on each other between the ball 8 simultaneously. Therefore, in the actual use process, when the locking pin is inserted into the cover 3 and enters the moving member 2, the ball 8 abuts against the locking pin and is locked by the friction between the ball 8 and the locking pin. And because the cover 3 is conical, the cover 3 can press the ball 8, thereby ensuring the stability of locking.

With reference to fig. 1 and 4, it can be seen that the unlocking structure specifically includes: at first, the two ends of the moving member 2 are provided with the pressing portions 4, so that in the actual use process, when a user wants to unlock, the user can press the pressing portions 4 to move the moving member 2, thereby unlocking.

And because the lock core is generally put inside, the whole volume of lock core is less simultaneously, if go to press with the hand, can be troublesome, therefore the user needs other parts to press moving member 2. And article such as the general impeller or the pressing member of adopting go to press moving member 2, and article such as impeller or pressing member are not the key of the utility model discloses, just for explanation, just the utility model discloses mainly be the structure of lock core.

Therefore, in the actual use process, when the locking nail is in a locked state, a user pushes the pushing piece or the pressing piece and other articles, and the front ends of the articles can press the pressing part 4 downwards, so that the moving piece 2 moves downwards and is unlocked.

Simultaneously, the dead lock structure above the cooperation, even the user uses article such as impeller or pressing member to press down pressing portion 4, ball 8 also can follow moving member 2 and move this moment to make the clearance between the ball 8 along with the downstream and enlarge, this is because lid 3 is the toper, so ball 8 is at the removal in-process, its space of locating can follow little grow along conical lid 3, therefore the clearance between the ball 8 also changes thereupon, and then make ball 8 can not support and lean on the staple, can take out the staple this moment, thereby the unblock.

The pressing portion 4 has various structures, for example, the upper surface of the pressing portion 4 is a plane, or a circular arc, or the two ends of the pressing portion 4 are formed with inclined surfaces 5. Therefore, can select according to the use scene, thereby the utility model discloses the suitability is strong. For example, when the upper surface of the pressing portion 4 is a flat surface, a pressing member that moves up and down may be used, and such a structure is relatively simple. For example, the inclined planes 5 formed at the two ends of the pressing part 4 can adopt pushing parts moving left and right, so that the vertical space can be reduced, and the whole space is further reduced. The event the utility model discloses the suitability is strong, can select under the different conditions to collocation.

Meanwhile, when the two ends of the pressing part 4 are formed with the inclined surfaces 5, both ends can be stressed, and can be pressed downwards along the inclined surfaces 5 from the front and can also be pressed downwards along the inclined surfaces 5 from the back, so that the mounting requirement is wide, and the pressing part only needs to be pressed to the inclined surfaces. Compare simultaneously originally the adoption be the magnet unblock, the utility model discloses a through pressing the unblock, therefore with low costs. Compare original rack structure simultaneously, the utility model discloses simple structure, one according to can the unblock.

Referring to fig. 2 and 4, it can be seen that a spring 6 is provided in the moving member 2. When unlocked, the spring 6 is compressed by pressing the moving member 2 downwards. Meanwhile, when the locking pin is taken out, a user can not apply force, so that the spring 6 is reset due to the self elasticity without external acting force, and the moving part is reset.

Referring to fig. 1 and 4, it can be seen that the two sides of the base 1 are provided with moving grooves 11 corresponding to the pressing portions 4. Therefore, in the actual use process, the pressing part 4 can move in the moving groove 11, and two ends of the moving groove 11 are not communicated, so that the moving part has a certain limit, and the pressing part 4 moves within a certain range, thereby having a certain protection effect on the lock cylinder.

Referring to fig. 2 and 3, it can be seen that the base 1 is provided with a second mounting groove 12, and the cover 3 is formed with a flange 13 by bending outwards. Therefore in actual installation, chimb 13 can the joint in second mounting groove 12 to connect base 1 and lid 3, chimb 13 and second mounting groove 12's looks adaptation can restrict lid 3's height moreover, thereby prevents that lid 3 from removing and droing.

The specific working process of the scheme is as follows:

in the actual use in-process, the staple can pass the article that is fixed earlier, then passes mounting hole 9 and connecting hole 10 in proper order to get into from lid 3 and reach moving member 2, ball 8 can lean on the staple this moment, thereby deadly through the friction between ball 8 and the staple.

And when the user will unblock, the user can press down and press splenium 4 and then press down moving member 2 to make moving member 2 move down, ball 8 also can follow moving member 2 to move this moment, thereby make the clearance between the ball 8 along with the downstream and enlarge, and then make ball 8 can not support and lean on the lock nail, can take out the lock nail this moment, thereby the unblock.
