Description

Technical Field

[0001] This utility model relates to the field of crane technology, specifically to a crane electrical cabinet door anti-detachment device. Background Technology

[0002] A crane is a multi-action lifting machine that vertically lifts and horizontally moves heavy objects within a certain range. The working characteristic of a crane is intermittent motion; that is, in a work cycle, the corresponding mechanisms for actions such as picking up, moving, and unloading materials work alternately. Cranes are becoming increasingly widespread in the market.

[0003] Currently, crane electrical cabinet doors are typically installed using screws and hinges. However, the vibrations generated during crane operation can cause the cabinet doors to detach or fail to close properly over time. Furthermore, once the door detaches, the original screw holes become unusable, necessitating innovative drilling for installation. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example

[0023] Please see Figures 1 to 4 The present invention provides a technical solution: a crane electrical cabinet door anti-detachment device, comprising a cabinet body 1 and a cabinet door 2. The cabinet body 1 is provided with a cabinet door 2 on one side. A fixed shaft 3 is rotatably connected to one side of the cabinet door 2. A handle 6 is fixedly connected to one end of the fixed shaft 3. A fixed plate 4 is fixedly connected to the other end of the fixed shaft 3. A fixed rod 5 is hinged to one side of the fixed plate 4. A fixed block 7 is slidably connected to one side of the cabinet door 2 at one end of the fixed rod 5. A positioning rod 8 is fixedly connected to one side of the fixed block 7. A positioning sleeve 9 adapted to the positioning rod 8 is fixedly connected to one side of the cabinet body 1. A first installation component 10 is fixedly connected to one side of the cabinet door 2.

[0024] Specifically, after the cabinet door 2 is closed, the fixing block 7, the positioning rod 8 and the positioning sleeve 9 connect the cabinet door 2 and the cabinet body 1 into one unit. After the cabinet door 2 is closed, normal vibrations will not cause the cabinet door 2 to fall off.

[0025] Please see Figure 4 The first mounting component 10 includes a mounting block 1001. A circular hole is provided on one side of the mounting block 1001. A mounting rod 1002 is slidably connected inside the circular hole. A mounting plate 1003 is fixedly connected to the outer surface of the mounting rod 1002. A sliding groove adapted to the mounting plate 1003 is provided inside the mounting block 1001. A spring 1004 that abuts against one side of the mounting plate 1003 is fixedly connected inside the sliding groove. A disc 1005 is fixedly connected to one end of the mounting rod 1002.

[0026] Specifically, there are two first mounting components 10. The first mounting components 10 connect the cabinet door 2 to the cabinet body 1 and enable the cabinet door 2 to rotate. The disc 1005 can pull the mounting rod 1002, so that the mounting rod 1002 is fully retracted into the mounting block 1001, making it easy to remove the cabinet door 2 if there is a problem.

[0027] Please see Figure 4 The cabinet 1 has a mounting hole on one side that is compatible with the mounting rod 1002.

[0028] Specifically, the mounting hole is rotatably connected to the mounting rod 1002 to enable the rotating installation of the cabinet body 1 and the cabinet door 2.

[0029] Please see Figure 4 The positioning sleeve 9 is fixedly connected to a first magnet 11, and one end of the positioning rod 8 is fixedly connected to a second magnet 12 that is compatible with the magnet.

[0030] Specifically, the first magnet 11 and the second magnet 12 can attract each other, which to a certain extent prevents the positioning tube from easily coming out of the positioning sleeve 9 due to vibration, thus ensuring the effectiveness of the anti-detachment device. Both the first magnet 11 and the second magnet are high-strength magnets to improve the adsorption strength.

[0031] Please see Figure 2 A limit rod 13 is fixedly connected to the inner wall of cabinet door 2, and one side of the limit rod 13 is slidably connected to one side of the fixing block 7.

[0032] Specifically, the limit rod 13 ensures that the fixed block 7 moves along the prescribed trajectory and that there are no problems when the handle 6 drives the fixed plate 4 to rotate, thus limiting the rotation angle of the fixed plate 4.

[0033] Please see Figure 2 A door lock 14 is fixedly connected to one side of cabinet door 2.

[0034] In use, close cabinet door 2, rotate handle 6, handle 6 drives fixed plate 4 to rotate through fixed shaft 3, fixed plate 4 drives fixed block 7 to move upward through fixed rod 5, fixed block 7 drives positioning rod 8 to move upward into positioning sleeve 9, and through the attraction between first magnet 11 and second magnet 12, positioning rod 8 can be prevented from coming out of positioning sleeve 9 due to vibration and other factors to a certain extent. In addition, fixed block 7, positioning rod 8 and positioning sleeve 9 can connect cabinet door 2 and cabinet body 1 together to prevent cabinet door 2 from falling off.

[0035] When cabinet door 2 malfunctions and needs to be removed, open cabinet door 2, pull disc 1005, disc 1005 will move mounting rod 1002, so that mounting rod 1002 comes out of the mounting hole in cabinet body 1, and cabinet door 2 can be easily removed.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
