[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figure 1-4 The present invention provides the following technical solution: an adjustable electrical box, including a box body 1, a first mounting plate 3 is provided on the inner side of the box body 1, a second mounting plate 7 is provided on the inner side of the box body 1 and below the first mounting plate 3, a plurality of mounting components 2 are installed near the center of the first mounting plate 3 and the second mounting plate 7, the box body 1 is connected to the first mounting plate 3 and the second mounting plate 7 by a connecting component 6, a push door component 8 is installed near the edge of the box body 1, a lifting and heat dissipation device 4 is provided on the outer side of the box body 1, and two drying and moisture-proof devices 5 are installed on the inner side of the box body 1 and above the first mounting plate 3.

[0023] Specifically, the lifting and cooling device 4 includes a lifting frame 41, a cooling component 42, screws 43, a support frame 44, and threaded holes 45. The support frame 44 is provided on the outside of the housing 1. The lifting frame 41 is installed on the outside of the housing 1 and inside the support frame 44. The top of the support frame 44 is screwed with screws 43. Multiple threaded holes 45 are opened on the side of the lifting frame 41 near the screws 43. The cooling component 42 is installed on the top and bottom of the housing 1.

[0024] By adopting the above technical solution, the staff can adjust the height of the box body 1 and other structures by means of the lifting frame 41 and threaded hole 45 when needed, so as to better meet the work needs in different situations.

[0025] Specifically, the heat dissipation component 42 includes a screw 421, a fan 422, a moving block 423, and a ventilation mesh 424. Ventilation mesh 424 is installed on the top and bottom of the housing 1. Moving blocks 423 are provided on both the upper and lower sides of the housing 1. A fan 422 is installed on the inner side of the moving block 423. The screw 421 is installed on the side of the moving block 423 away from the multiple threaded holes 45 via a bearing.

[0026] By adopting the above technical solution, staff can ventilate and dissipate heat inside the enclosure 1 when needed through the cooperation of structures such as fan 422 and ventilation net 424, thereby reducing the possibility of overheating and damage to electrical components installed inside the enclosure 1.

[0027] Specifically, the distance between the two moving blocks 423 is equal to the height of the outer side of the box 1.

[0028] By adopting the above technical solution, the electrical box can ensure that the two moving blocks 423 are in close contact with the box body 1, thereby preventing the moving blocks 423 from rotating or shifting during movement and ensuring normal operation.

[0029] In this embodiment, when the electrical box is needed, the operator rotates the screw 43 on the support frame 44 of the lifting and cooling device 4 to disengage it from the threaded hole 45 on the lifting frame 41. Then, the lifting frame 41 is pulled to move it and the box 1 and other structures to the required height. The screw 43 is then rotated in the opposite direction to connect it with the corresponding threaded hole 45. The push door assembly 8 is then opened, and the electrical components required for the electrical box are installed through the various mounting components 2 on the first mounting plate 3 and the second mounting plate 7. The push door assembly 8 is then closed. If ventilation and heat dissipation of the interior of the box 1 are required, the fans 422 in the two heat dissipation components 42 are activated. Under the action of the two fans 422, outside air is drawn from the top of the box 1. The ventilation mesh 424 enters the housing 1, and then carries the heat inside the housing 1 through the ventilation mesh 424 at the bottom of the housing 1 to be discharged, thereby ventilating and dissipating heat. If ventilation and heat dissipation are not required, the operator can rotate the two screws 421 respectively. The screws 421 are threadedly connected to the lifting frame 41, and the screws 421 are bearing connected to the moving block 423. The moving block 423 is in close contact with the housing 1, so the two screws 421 drive the two moving blocks 423 and the fan 422 inside to move until the two ventilation meshes 424 are closed by the two moving blocks 423, thereby preventing ventilation and heat dissipation. Then the operator can work through the various electrical components installed. The connecting component 6 plays a connecting role.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that the drying and moisture-proof device 5 includes a mesh cylinder 51, a fixing ring 52 and a silica gel desiccant 54. Two fixing rings 52 are installed on the inner side of the box body 1 and above the first mounting plate 3. Two mesh cylinders 51 are arranged between the first mounting plate 3 and the two fixing rings 52. The inner side of the mesh cylinder 51 is filled with silica gel desiccant 54.

[0032] By adopting the above technical solution, staff can dry the inside of the box 1 when needed by using the mesh tube 51 and silica gel desiccant 54, thereby reducing the possibility of electrical components installed in the box 1 being damaged by moisture.

[0033] Specifically, the drying and moisture-proof device 5 also includes a threaded ring 53, which is installed above the mesh cylinder 51 and inside the fixing ring 52.

[0034] By adopting the above technical solution, workers can connect or separate the mesh cylinder 51 and the fixed ring 52 through the threaded ring 53 when needed, which facilitates the loading and unloading of the mesh cylinder 51.

[0035] In this embodiment, when needed, the operator can put enough silica gel desiccant 54 into the mesh cylinders 51 of the two drying and moisture-proof devices 5, open the push door assembly 8, connect the threaded rings 53 on the two mesh cylinders 51 to the fixed rings 52 through the threads, close the push door assembly 8, and the moisture in the box 1 will be gradually absorbed by the silica gel desiccant 54, thereby reducing the possibility of electrical components installed in the box 1 being damaged by moisture.

[0036] The structure and principle of the box body 1, the mounting assembly 2 consisting of a mounting opening, a third telescopic spring, and an arc-shaped plate, the first mounting plate 3, the connecting assembly 6 consisting of a sliding groove, a sliding rod, a through hole, a first round tube, a first movable rod, a first telescopic spring, and a second telescopic spring, the second mounting plate 7, and the push door assembly 8 consisting of a hinge, a push door, and a handle, are disclosed in Chinese Patent Application No. 201720621100.5, which describes an easy-to-use electrical box. Its working principle is as follows: during use, the arc-shaped plate is moved outwards and placed in position. Then, the arc-shaped plate is released, and the first mounting plate moves downwards, sliding on the sliding rod. The first movable rod moves on the first round tube, and the elasticity of the first telescopic spring stabilizes the first mounting plate, or increases the gap between the first and second mounting plates, making it easier to install heavier or larger electrical components, thus enhancing the practicality of the electrical box.

[0037] The working principle and usage process of this utility model are as follows: When the electrical box needs to be used, the operator rotates the screw 43 on the support frame 44 of the lifting and cooling device 4 to disengage it from the threaded hole 45 on the lifting frame 41. Then, the lifting frame 41 is pulled to move it and the box body 1 and other structures to the required height. The screw 43 is rotated in the opposite direction to connect it with the corresponding threaded hole 45. Then, the push door assembly 8 is opened, and the electrical components required by the electrical box are installed through the various mounting components 2 on the first mounting plate 3 and the second mounting plate 7. The push door assembly 8 is then closed. If ventilation and heat dissipation of the inside of the box body 1 are required, the fans 422 in the two heat dissipation components 42 are activated. Under the action of the two fans 422, outside air enters the box body 1 through the ventilation net 424 at the top of the box body 1, and then carries the heat inside the box body 1 through the ventilation net 424 at the bottom of the box body 1 to be discharged, thereby achieving ventilation and heat dissipation. If ventilation and heat dissipation are not required, The operator can rotate the two screws 421 respectively. The screws 421 are threadedly connected to the lifting frame 41, and the screws 421 are bearing-connected to the moving block 423. The moving block 423 is in close contact with the box 1. Therefore, the two screws 421 drive the two moving blocks 423 and the fan 422 inside to move until the two ventilation screens 424 are closed by the two moving blocks 423, thereby preventing ventilation and heat dissipation. Then the operator can work through the various electrical components installed. The connecting component 6 plays a connecting role. When needed, the operator can put enough silica gel desiccant 54 into the mesh cylinders 51 of the two drying and moisture-proof devices 5, open the push door component 8, connect the threaded rings 53 on the two mesh cylinders 51 to the fixed rings 52 through the threads, close the push door component 8, and the moisture in the box 1 will be gradually absorbed by the silica gel desiccant 54, thereby reducing the possibility of the electrical components installed in the box 1 being damaged by moisture.
