[0025] The cabinet door lock installation structure provided in this embodiment, compared with the prior art, is provided with a cabinet body 1. A door panel 12 is hinged on one side of the cabinet body 1, and cross beams 11 are installed at the top and bottom inside the cabinet body 1. When the door panel 12 is closed, the sealing strip on the door panel 12 can abut against the outer side surface of the cross beam 11 to achieve the sealing between the door panel 12 and the inside of the cabinet body 1. In this application, a moving rod 2 is installed on the door panel 12, and the length direction of the moving rod 2 is arranged vertically. And the moving rod 2 is slidably arranged on the door panel 12 in the vertical direction by the drive of the lock. A limiting rod 21 for limiting to the inner side of the cross beam 11 inside the cabinet body 1 is arranged at the top of the moving rod 2. A swing rod 3 is installed at the bottom of the moving rod 2. The middle of the swing rod 3 is hinged on the door panel 12. One end of the swing rod 3 is provided with an oblong through hole whose length direction is along the length of the swing rod 3. The bottom end of the moving rod 2 is installed with a hinge shaft slidably arranged inside the oblong through hole. When this application is in use, the lock can be used to push the moving rod 2 downward first, so that the limiting rod 21 is disengaged from the top cross beam 11 of the cabinet body 1. The swing rod 3 at the bottom swings upward under the drive of the moving rod 2 and is disengaged from the cross beam 11 at the bottom of the cabinet body 1, so that the door panel 12 can be opened. After the door panel 12 is closed, the lock is used to control the moving rod 2 to move downward, so that the limiting rod 21 and the swing rod 3 are respectively limited to the inner sides of the top and bottom cross beams 11 inside the cabinet body 1, so that the sealing strips at the top and bottom of the door panel 12 can effectively fit on the cross beam 11, effectively improving the sealing effect between the cabinet body 1 and the door panel 12.

[0026] Specifically, in this embodiment, the vertical distance from the hinge joint of the swing rod 3 and the door panel 12 to the door panel 12 is greater than the vertical distance from the hinge shaft at the bottom end of the moving rod 2 to the door panel 12.

[0027] Specifically, in this embodiment, a rib plate protrudes on the side of the cross beam 11 close to the door panel 12, and the sealing strip on the door panel 12 abuts against the rib plate. The limiting rod 21 is located at the top end of the moving rod 2, and the limiting rod 21 is located on the side of the moving rod 2 away from the door panel 12, so that when the door panel 12 is closed to the cabinet body 1, the limiting rod 21 can abut against the inner side of the cross beam 11.

[0028] Specifically, in this embodiment, the lock is not marked in the figure and is a purchased standard part, which is fixedly installed on the door panel. The specific structure will not be elaborated here. The lock can adopt a connecting rod lock, and the connecting rod on the lock is connected to the moving rod 2 to drive the moving rod 2 to move up and down.

[0029] In some embodiments, the above-mentioned limiting rod 21 can adopt a structure such as Figure 2 shown. Refer to Figure 2, the limiting rod 21 is arranged parallel to and spaced from the moving rod 2, and a first roller 211 for abutting against the inner side of the cross beam 11 is rotatably arranged at the end of the limiting rod 21. A first roller 211 is rotatably arranged at the top end of the limiting rod 21. When the door panel 12 is closed onto the cabinet body 1, the moving rod 2 can be driven to move upward by the lock. When the moving rod 2 moves upward, the first roller 211 first contacts the cross beam 11 at the top of the cabinet body 1 and guides the limiting rod 21 to move upward. Through the guidance of the first roller 211, the sealing strip on the door panel 12 can be more closely attached to the cabinet body 1. At the same time, it can prevent the limiting rod 21 from interfering with the cross beam 11 at the top of the cabinet body 1 and affecting the locking of the door panel 12 on the cabinet body 1.

[0030] In some embodiments, the above-mentioned moving rod 2 can adopt a structure as shown in Figure 2 . Refer to Figure 2 , a guiding hole is arranged on the moving rod 2 along the vertical direction, and a guiding rod 212 is fixedly installed on the door panel 12, and the guiding rod 212 is slidably arranged inside the guiding hole. A guiding hole is arranged on the side wall of the moving rod 2 close to the door panel 12, and the length direction of the guiding hole is arranged along the vertical direction. A guiding rod 212 is fixedly installed on the door panel 12, and the guiding rod 212 is located inside the guiding hole and is slidably matched with the inner wall of the guiding hole. Thus, the moving rod 2 can be guided to slide smoothly along the vertical direction on the door panel 12.

[0031] Preferably, in this embodiment, the number of guiding holes is multiple, and the multiple guiding holes are arranged at intervals in sequence along the vertical direction on the moving rod 2, and a guiding rod 212 is correspondingly arranged inside each guiding hole.

[0032] In some embodiments, the above-mentioned guiding rod 212 can adopt a structure as shown in Figure 2 .

Two fasteners 42 are threadedly connected to the connecting shaft 41, and the connecting plate on the mounting bracket 4 is clamped between the two fasteners 42. Thus, the connecting shaft 41 can be fixed to the mounting bracket 4. At the same time, the position of the connecting shaft 41 on the mounting bracket 4 along the axis direction of the connecting shaft 41 can be adjusted. Facilitate the connection with the moving rod 2 in the later stage.

[0035] Specifically, in this embodiment, a lower inclined plate is fixedly installed at the bottom end of the moving rod 2, and the lower inclined plate is inclined downward and away from the door panel 12 from top to bottom.

[0036] Specifically, in this embodiment, the connecting shaft 41 on the mounting bracket 4 adopts a bolt, and a gasket is arranged between the fastener 42 and the nut, and the lower inclined plate at the bottom end of the moving rod 2 is installed between the gasket and the nut.

When the door panel 12 is closed, the second roller 421 is used to support on the bottom plate in the cabinet body 1 and is located at a position of the bottom plate close to the door panel 12. When the door panel 12 is closed, the second roller 421 preferentially moves onto the bottom plate in the cabinet body 1 to play a role in supporting the door panel 12. Improve the stability of the position when the door panel 12 is closed. Prevent the phenomenon that the door panel 12 cannot be closed due to the sinking of the door panel 12. At the same time, ensure the position of the mounting bracket 4, so as to ensure that after the moving rod 2 moves down a certain distance, the swing rod 3 can abut against the inner wall of the bottom cross beam 11 of the cabinet body 1.

[0038] Specifically, in this embodiment, a mounting shaft for mounting the second roller 421 is fixedly installed on the connecting plate of the mounting frame 4. The second roller 421 is rotatably arranged on the mounting shaft.

[0039] Preferably, in this embodiment, the number of the second rollers 421 is two. The two second rollers 421 are respectively located on the outer sides of both sides of the mounting frame 4 along the axis of the mounting shaft, and the two second rollers 421 share the same mounting shaft.

[0040] In some embodiments, the above-mentioned moving rod 2 can adopt a structure as Figure 2 and Figure 3 shown. Referring to Figure 2 and Figure 3 collectively, the moving rod 2 includes a moving plate 22 slidably arranged on the door panel 12 and reinforcing plates 23 bent on both sides of the moving plate 22. The guiding holes are located on the moving plate 22, and guiding holes are provided at both ends of the moving plate 22. The moving rod 2 is formed by bending a steel plate, which reduces the processing cost of the moving rod 2, and the size of the moving rod 2 can be freely adjusted according to the size of the cabinet body 1. The reinforcing plates 23 are located at both side edges of the moving plate 22 in the width direction, which can strengthen the overall strength of the moving rod 2. And guiding holes are provided at both ends of the moving rod 2, and the two ends of the moving rod 2 can be guided by the guiding rods 212 located on the door panel 12. Ensure the stability of the movement of both ends of the moving rod 2.

[0041] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention.
