[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0029] Example 1: Referring to Figures 1, 2, and 3, this utility model provides a locking device for locking the door frame A and door body B of a server rack. The door frame A has a stepped edge adapted to the thickness of the door body B.

[0030] Support 1, which is connected to the door body;

[0031] Sliding shaft 2 is connected to support 1;

[0032] The pin 3 has an elongated hole 31 and is movably connected to the slide shaft 2 through the elongated hole 31. A screw 32 is threaded onto the pin 3, and a handle 33 is connected to one end of the screw 32.

[0033] The latch 4 is connected to the door frame and corresponds to the position of the support 1. The latch 4 has a plug hole 41 for inserting one end of the pin 3. When the pin 3 is inserted into the plug hole 41 and the screw 32 is tightened, the door body B abuts against the step edge of the door frame A.

[0034] Specifically, when locking the cabinet, first push the pin 3 to slide towards the latch 4, so that the front end of the pin 3 is inserted into the insertion hole 41 of the latch 4; then rotate the screw 32 by the handle 33, so that the end of the screw 32 near the support 1 gradually abuts against the bottom surface of the support 1. After abutting, rotate the handle 33 further, so that the screw 32 gradually lifts the front end of the pin 3, and the pin 3 abuts against the side of the insertion hole 41 away from the door frame, thereby locking the door frame and the door body; at the same time, during the process of tightening the screw 32, the included angle between the support 1 and the pin 3 will gradually increase, which will further compress the sealing gasket C set between the door body and the door frame, improving the sealing effect. When opening the cabinet, simply turn the handle 33 in the opposite direction to gradually separate the end of the screw 32 near the support 1 from the bottom surface of the support 1. During this process, the force between the pin 3 and the insertion hole 41 gradually decreases and eventually separates. Then push the pin 3 to slide away from the latch 4, so that the pin 3 can be pulled out from the insertion hole 41, thus unlocking the door frame and the door.

[0035] This utility model discloses a locking device, comprising a support 1 and a latch 4 respectively installed on the door body and door frame. A pin 3 is movably connected to the support 1 via a sliding shaft 2. Simultaneously, a screw 32 threadedly connected to the support 1 adjusts the angle of the front end of the pin 3, thereby causing the pin 3, inserted into the insertion hole 41 of the latch 4, to abut (interact) with the latch 4 to achieve locking. During the locking process, none of the components of the locking device rub against the door frame or door body, thus preventing scratches on the cabinet surface and maximizing the protection of the protective coating on the cabinet surface, which helps to extend the service life of the cabinet. Furthermore, the locking and unlocking processes are relatively simple, requiring minimal force to achieve locking and unlocking.

[0036] Furthermore, the support 1 is a U-shaped groove structure, including a first base plate and two first side plates that are perpendicularly connected to it. The first base plate is fixedly connected to the door body, and the sliding shaft 2 is perpendicularly connected between the two first side plates.

[0037] Furthermore, the pin 3 has a U-shaped groove structure, including a second base plate and two second side plates perpendicularly connected to it. Two elongated holes 31 extending along the length of the two second side plates are coaxially formed on them and are movably connected to the sliding shaft 2 through the elongated holes 31. A screw 32 perpendicular to the base plate is threadedly connected to it, and the screw 32 is located between the elongated holes 31 and the latch 4. A handle 33 is connected to the end of the screw 32 away from the support 1. Specifically, the support 1, pin 3, and latch 4 are all sheet metal parts, which can be manufactured by the factory using scrap materials from other products, greatly reducing production costs; material costs are negligible. Compared with some locking mechanisms currently purchased from the market, the manufacturing cost is significantly reduced. Specifically, the width of the pin 3 is less than the distance between the inner walls of the two first side plates of the support 1, so that the pin 3 can be embedded between the two first side plates, which not only facilitates operation by the operator but also limits the position of the pin 3.

[0038] Furthermore, a mounting hole is vertically provided on the second base plate, and a threaded base 34 is coaxially connected in the mounting hole, with the screw 32 threadedly connected to the threaded base 34.

[0039] Furthermore, a limiting protrusion 35 is vertically provided on the side of the second base plate away from the first base plate, and the limiting protrusion 35 is located at the end of the second base plate near the latch 4. Specifically, after the pin 3 is inserted into the insertion hole 41 on the latch 4 and the screw 32 is gradually tightened, the limiting protrusion 35 will be stuck on the side of the latch 4 away from the support 1, thereby restricting the relative movement between the latch 4 and the pin 3. In this way, after the locking device is locked, even if the engagement between the pin 3 and the latch 4 becomes loose due to bumps or vibrations during transportation, it can still be ensured that the pin 3 will not slip out of the insertion hole 41, thus ensuring the locking effect.

[0040] Furthermore, the latch 4 includes a main body and an end plate. The main body has a U-shaped groove structure, including a third base plate and two third side plates that are vertically connected to it. The end plate is vertically connected to the end face of the third base plate and the two third side plates at the same end. The end plate is connected to the door frame. A plug hole 41 is vertically opened on the third base plate.

[0041] Furthermore, an abutment plate 42 is vertically provided on the side of the third base plate away from the support 1. The abutment plate 42 is located on the side of the insertion hole 41 away from the door frame. Specifically, the abutment plate 42 is used to abut against the limiting protrusion 35, which not only improves the structural strength of the abutment position between the latch 4 and the bolt 3 and ensures the stability when locking, but also avoids the limiting protrusion 35 from directly contacting the latch 4 body, which is beneficial to improving the service life of the latch 4.

[0042] Referring to Figure 4, more preferably, an arc-shaped limiting groove 311 is provided on the side wall of the end of the elongated hole 31 away from the screw 32. Specifically, the limiting groove 311 is located on the side near the bottom surface of the support 1. During the locking process, the sliding shaft 2 can be embedded in the limiting groove 311 to prevent the pin 3 from sliding.

[0043] Furthermore, the handle 33 includes a cylindrical body with multiple arc grooves arranged in a circular array around its circumference on the side of the body, forming a star-like shape, which makes it convenient for the operator to grip and rotate.

[0044] Example 2: This utility model also discloses a cabinet, including the locking device as in Example 1.

[0045] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
