Description

Sliding plate pre-lock mechanical lock

(1) Technical field

The utility model relates to a sliding plate pre-locking mechanical lock.

(2) Background technology

The bezel lock has a simple structure and low cost, and is mostly used in furniture, such as drawers, boxes, cabinets, etc., where the safety requirements are relatively low, and it is also applied to products such as power switches controlled by key locks.

Generally, the sliding plate mechanical lock can be opened with a universal lock unlocking tool for opening a steel ball lock; at present, the unlocking tool uses the first tool to gently twist the lock core to the opening direction, because the position of the sliding plate will cause interference, so the lock core cannot be rotated. Then use the second tool to strike the sliding plate. Because of the manufacturing accuracy error, only one sliding plate will interfere instead of all the sliding plates at the same time. When the sliding plate with the largest interference is knocked down When in the open position, the lock core will temporarily lose interference and will turn slightly in the opening direction, and at the same time lock the sliding plate at this position. At this time, this group of sliding plates has failed. Repeatedly knocking on the sliding plates will make all the sliding plates After failure, the lock core can be rotated to open the lock.

(5) specific implementation

The structure of the sliding plate pre-locking type mechanical lock of the present utility model is shown in Figure 1, and it comprises:

A lock body 3, which can cooperate with a hexagonal nut 12 to be installed and fixed on the panels of drawers, cabinets and other places of use;

A lock core 2 is threaded and assembled in the lock body 3, and a C-shaped buckle 13 is fastened and positioned at the position where its near end passes through the lock body 3, so that the lock core 2 will not come out of the lock body 3 ;

A lock core positioning piece 4, accommodated on one side of the lock core 2 assembled in the lock body 3, and can rotate with the lock core 2;

Several sliding plates 5-8 are accommodated in the lock core 2;

A baffle 9 is fixedly combined with the screw 14 at the end of the lock core 2, and can rotate with the lock core 2 to provide opening and closing control;

A lock body fixing plate 10, which is sleeved and assembled on the outside of the lock body 3, and can be fixed on the inside of the panel at the use position to prevent the lock body 3 from rotating;

The lock core positioning piece spring 11 is assembled between the lock core 2 and the lock core positioning piece 4, and is used to push the lock core positioning piece 4 into the inner positioning groove of the lock body 3;

A key 1 can be inserted into the key hole of the lock core 2 to move and control the position of the sliding plates 5-8, and can be used to rotate the lock core 2 to drive the baffle plate 9 to open or close the mechanical lock of the present utility model.

The utility model principle and action are described as follows:

Before the key 1 is inserted into the key hole of the lock core 2, the outer edge of the lock core positioning piece 4 will fall into the positioning groove inside the lock body 3 (the cross section of the positioning groove shown in Figure 3 is V-shaped, and it can also be arc-shaped. Or semi-circular shapes), so that the lock core positioning piece 4 does not contact with the sliding plates 5-8, so the sliding plates 5-8 can move up and down freely, before the key 1 is inserted into the key hole of the lock core 2, the sliding plate 5-8 are somewhat higher and some are lower (as shown in Figure 2 or Figure 4), if the lock core 2 rotates, it will be interfered by the edges of slots 31 and 32 on the lock body 3, and now the sliding plates 5-8 The two ends are aligned with the slots 31 and 32 on the lock body 3, so the sliding plates 5-8 can move up and down with the key 1 cam without interfering with the lock body 3. At this time, the key 1 can be inserted and pulled out of the lock core at will. 2 key holes, when the correct key 1 is inserted into the key hole of the lock core 2, the sliding plates 5-8 will be pushed to the positions shown in Figures 5 and 6, so that both ends of the sliding plates 5-8 are retracted into the lock In the core 2, when the lock core 2 is rotated, the sliding plates 5-8 will not interfere with the edges of the slots 31 and 32 on the lock body 3, and the lock core 2 can be smoothly rotated to open the mechanical lock of the present invention;

In the utility model, when the lock core 2 is rotated to the unlocked or locked position, positioning grooves are respectively provided on the inner side of the lock body 3 corresponding to the position of the lock core positioning piece 4, so that when the lock core 2 rotates 90 degrees, the lock core positioning piece 4 will fall into the groove (as shown in Figure 8), providing the user with a positioning feel, and at this time the sliding plates 5-8 are aligned with the slots 33 and 34 on the lock body 3, and the key 1 can be pulled out smoothly or Insert.

If the key inserted in the key hole of the lock core 2 is incorrect or when other tools are used to rotate the lock core 2, there are still some gaps between the edges of the sliding plates 5-8 at the locked position from the edges of the slots 31 and 32 of the lock body 3. Therefore, the sliding plates 5-8 will not interfere with the lock body 3 when starting to turn the lock core 2, so the lock core 2 can be rotated about 5 degrees regardless of whether the key 1 is correct or whether the key 1 is inserted (the angle depends on the design). It is not limited to 5 degrees), when the lock core 2 rotates to 5 degrees, the lock core positioning piece 4 that is displaced with the lock core 2 rotation will break away from the positioning groove inside the lock body 3 and be pushed to the lock core 2 direction, so that the lock core positioning piece 4 is close to the sliding plates 5-8, and the sliding plates 5-8 are locked (as shown in Figure 7), which will make the universal unlocking tool unable to push the sliding plates 5-8, and also That is to say, if the key 1 is incorrect, all or some of the sliding plates 5-8 will interfere with the edge positions of the slots 31 and 32 of the lock body 3, as long as any one of the sliding plates 5-8 interferes with the lock body 3, it will not be possible to Continue to rotate the lock core 2, so that the mechanical lock of the present utility model cannot be opened.

Another feature of the utility model is that the sliding plates 5-8 are directly driven by the key 1 without being pushed by the spring. Generally, the sliding plates are pushed to the tooth-shaped end of the key by the spring. The tooth shape of the key of the utility model is a two-way positioning cam. , the sliding plates 5-8 will be pushed by the key 1 to the set position without interfering with the lock body. When the key 1 is pulled out, all the holes of the sliding plates 5-8 will be pushed to the central position. This design can save all The sliding plate pushes the spring.

Of course, those of ordinary skill in the art should recognize that the above embodiments are only used to illustrate the utility model, rather than as a limitation to the utility model, as long as within the spirit of the utility model, the above The changes and modifications of the embodiments will all fall within the scope of the claims of the present utility model.
