Referring to fig. 1 to 5 in combination, an embodiment of the present utility model provides a locking mechanism 100 for locking a cabinet body 200 and a cabinet door 300, which includes a mounting seat 110 and a locking protrusion 120, wherein the mounting seat 110 is fixedly arranged on the cabinet body 200, the locking protrusion 120 is slidably arranged on the cabinet door 300, a locking groove 111 is arranged on the mounting seat 110, and the locking protrusion 120 is driven to slide relative to the cabinet door 300, so that the locking protrusion 120 slides into the locking groove 111 to be locked. The locking mechanism 100 can solve the problems that the traditional world lock 400 cannot meet the requirements of a cabinet and has higher protection level.

It should be noted that, as shown in fig. 1 and fig. 2, the locking mechanism 100 is used for realizing the locking connection between the cabinet body 200 and the cabinet door 300, specifically, the locking mechanism 100 includes a mounting seat 110 and a locking protrusion 120, wherein the mounting seat 110 is fixedly disposed on the cabinet body 200, a locking groove 111 is disposed on the mounting seat 110 to realize locking by matching the locking protrusion 120 with the locking groove 111, and the locking protrusion 120 is slidably disposed on the cabinet door 300, so that the locking protrusion 120 can slide relative to the cabinet door 300, thereby changing the relative position between the locking protrusion 120 and the mounting seat 110, i.e. changing the relative position between the locking protrusion 120 and the locking groove 111.

On the basis, when an operator applies external force to drive the locking protrusion 120 to slide towards one side close to the mounting seat 110 relative to the cabinet door 300, the locking protrusion 120 can gradually slide into the locking groove 111, so that locking of the locking protrusion 120 and the locking groove 111 is realized, locking connection of the cabinet body 200 and the cabinet door 300 is realized, and the cabinet can meet requirements of tighter use requirements and higher protection level; on the contrary, when the operator applies the external force to drive the locking protrusion 120 to slide towards the side far away from the mounting seat 110 relative to the cabinet door 300, the locking protrusion 120 can gradually slide out from the locking groove 111, so as to unlock the locking protrusion 120 and the locking groove 111, and further separate and open the cabinet body 200 and the cabinet door 300, thereby ensuring that the operator performs normal operation and daily maintenance on the control electric appliance inside the cabinet.

Compared with the conventional world lock 400 in the prior art, the locking mechanism 100 provided by the utility model only realizes the locking for the upper and lower ends of the cabinet, but cannot ensure the tightness of the middle position of the cabinet, as shown in fig. 3 and 4, can be suitable for any height position of the cabinet, namely, the mounting seat 110 and the locking protrusion 120 can be reasonably arranged in pairs along the height direction of the cabinet according to actual requirements, thereby ensuring the tightness of any position of the cabinet along the height direction of the cabinet, and further solving the problems that the conventional world lock 400 cannot meet the requirements of the use of the cabinet and has higher protection level.

As shown in fig. 1 and 2, in the present embodiment, the width of the locking groove 111 is equal to the outer diameter of the locking protrusion 120, so that the locking protrusion 120 can smoothly slide into the locking groove 111 without shaking in the locking groove 111, thereby further ensuring the tightness between the cabinet 200 and the cabinet door 300.

It should be noted that, the width of the locking groove 111 herein refers to the width of the locking groove 111 in the direction of the connection line of the cabinet 200 and the cabinet door 300, and similarly, the outer diameter of the locking protrusion 120 herein refers to the outer diameter of the locking protrusion 120 in the direction of the connection line of the cabinet 200 and the cabinet door 300, and the outer diameter of the locking protrusion 120 herein refers to the maximum width of the locking protrusion 120 in the direction of the connection line of the cabinet 200 and the cabinet door 300, regardless of the cross-sectional shape of the locking protrusion 120 being any figure (e.g., circular, elliptical, rectangular, pentagonal, hexagonal, etc.).

Since some wear is inevitably generated to the locking groove 111 and the locking protrusion 120 when the locking mechanism 100 is used for a long time, even though the locking protrusion 120 slides into the locking groove 111 to achieve locking, a minute gap may still exist between the cabinet 200 and the cabinet door 300. In order to solve the above-described problem, as shown in fig. 1 and 2, in the present embodiment, the locking groove 111 extends obliquely in the direction from the cabinet door 300 to the cabinet body 200.

In this way, when the locking mechanism 100 is used for a short time, the locking protrusion 120 only needs to slide into the locking groove 111 for a short distance, so as to exert a certain tensioning force on the mounting seat 110 (i.e. the cabinet body 200), thereby ensuring the locking connection between the cabinet body 200 and the cabinet door 300; when the locking mechanism 100 is used for a long time, the locking protrusion 120 only needs to slide into the locking groove 111 for a long distance, and still can exert a certain tensioning force on the mounting seat 110 (i.e. the cabinet body 200), so as to ensure the locking connection between the cabinet body 200 and the cabinet door 300.

As shown in fig. 2, in the present embodiment, a guide portion 112 is provided at the opening of the locking groove 111, and the guide portion 112 is used for guiding the locking protrusion 120 to slide into the locking groove 111, so as to ensure that the locking protrusion 120 can slide into the locking groove 111 easily even if an operator performs a blind operation on the locking protrusion 120.

As shown in fig. 1 and 2, in the present embodiment, the locking mechanism 100 further includes a fastener 130, and the mounting base 110 is provided with a connection hole 113, and the fastener 130 is disposed through the connection hole 113, so that the mounting base 110 is fixedly connected with the cabinet 200. It should be noted that, the cabinet 200 should be provided with corresponding mounting holes, that is, the fastening members 130 sequentially penetrate through the connecting holes 113 and the mounting holes, so that the mounting base 110 is fixedly connected with the cabinet 200. For example, the fastener 130 may be a standard such as a screw.

As shown in fig. 1 and 2, in this embodiment, the connecting hole 113 is a kidney-shaped hole, and the kidney-shaped hole extends along the connecting line direction of the cabinet body 200 and the cabinet door 300, so that the position of the mounting seat 110 relative to the cabinet body 200 (or the cabinet door 300) is adjustable, that is, the position of the locking groove 111 relative to the locking protrusion 120 is adjustable, and the fastener 130 abuts against one side of the mounting seat 110 facing away from the cabinet body 200, so as to ensure that the mounting seat 110 is fixedly connected with the cabinet body 200, and also solve the problem of poor tightness between the cabinet body 200 and the cabinet door 300 after the long service time of the locking mechanism 100. Illustratively, the shafts of the screws are sequentially inserted into the connecting holes 113 and the mounting holes, and the nuts of the screws are abutted against one side of the mounting seat 110 away from the cabinet 200. It should be noted that, since fig. 1 and 2 are cross-sectional views, only the fastener 130 can be seen to penetrate the connecting hole 113, and it cannot be seen that the fastener 130 abuts against the side of the mounting base 110 facing away from the cabinet 200.

Specifically, when the locking mechanism 100 is used for a short time, the fastener 130 may be inserted into one end of the connecting hole 113 away from the cabinet door 300 and abutted against one side of the mounting seat 110 away from the cabinet body 200, so that the mounting seat 110 can exert a certain tensioning force on the locking protrusion 120 (i.e., the cabinet door 300), thereby ensuring the locking connection between the cabinet body 200 and the cabinet door 300; when the locking mechanism 100 has a long service life, the fastener 130 may be inserted through the end of the connecting hole 113 near the cabinet door 300 and tightly abutted against the side of the mounting seat 110 away from the cabinet body 200, so that the mounting seat 110 can exert a certain tension on the locking protrusion 120 (i.e. the cabinet door 300), thereby ensuring the locking connection between the cabinet body 200 and the cabinet door 300.

As shown in fig. 1 and 2, in the present embodiment, the extending direction of the fastener 130 and the extending direction of the locking protrusion 120 are parallel to each other. Specifically, the fastening member 130 is fixed to the cabinet 200 in a direction perpendicular to the cabinet 200, and the locking protrusion 120 is fixed to the cabinet door 300 in a direction perpendicular to the cabinet door 300, so as to ensure that no included angle exists between the fastening member 130 and the locking protrusion 120, thereby avoiding the influence on the relative movement between the locking protrusion 120 and the locking groove 111.

The embodiment of the utility model also provides a cabinet, which comprises a cabinet body 200, a cabinet door 300 and the locking mechanism 100, wherein the cabinet body 200 is in fit contact with the cabinet door 300 and is in locking connection through the locking mechanism 100. Since the structure and the advantages of the locking mechanism 100 are described in detail in the foregoing embodiments, they are not described in detail herein.

As shown in fig. 3 and 4, in the present embodiment, the cabinet further includes a top-bottom lock 400, and the locking protrusion 120 is fixedly disposed on a link 410 of the top-bottom lock 400, so as to drive the locking protrusion 120 to slide relative to the locking groove 111 by sliding the link 410 of the top-bottom lock 400 relative to the cabinet door 300. By providing the top-bottom lock 400, it is more convenient for an operator to apply an external force to the locking protrusion 120.

As shown in fig. 5, optionally, a guide block 310 with a sliding groove 311 is fixedly arranged on the cabinet door 300, and a connecting rod 410 is slidably arranged in the sliding groove 311, so that the sliding of the connecting rod 410 relative to the cabinet door 300 is guided by the guide block 310, and the movement track of the locking protrusion 120 is always stable and reliable.

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
