Obviously, the described embodiments are only some embodiments of the present utility model, rather than 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 efforts belong to the scope of protection of the present utility model.

[0026] The present utility model provides a technical solution:

[0027] Embodiment 1:

[0028] Combined with Figures 1 to 2 -3, a mine explosion-proof and intrinsically safe power supply cabinet includes a support base 1, a power supply cabinet body 4 is arranged on the top of the support base 1, buffer mechanisms 3 are arranged on both sides of the power supply cabinet body 4, and an installation mechanism 2 is arranged on the front side of the power supply cabinet body 4.

[0029] The installation mechanism 2 includes a baffle 204. The baffle 204 is arranged on the front side of the power supply chassis body 4. Connecting plates 201 are fixedly connected to both the top and bottom of the baffle 204. A clamping groove is formed in the connecting plate 201, and a clamping rod 24 is clamped in the clamping groove. A sliding plate 25 is fixedly connected to the surface of the clamping rod 24. A fixed rod 27 is slidably connected to the top of the sliding plate 25. First support members 22 are fixedly connected to both sides of the surface of the fixed rod 27, and the first support members 22 are fixedly connected to the surface of the power supply chassis body 4.

[0030] Further, a first spring 23 is sleeved on the surface of the fixed rod 27. The first spring 23 is arranged between the sliding plate 25 and the right first support member 22. By providing the first spring 23, the clamping rod 24 can be moved.

[0031] Further, a telescopic rod 26 is fixedly connected to the side of the sliding plate 25 away from the clamping rod 24. A fixing block 202 is fixedly connected between the two telescopic rods 26, and the fixing block 202 is fixedly connected to the surface of the power supply chassis body 4. By providing the telescopic rod 26, the phenomenon that the sliding plate 25 tilts during movement can be avoided.

[0032] Further, the number of the clamping rods 24 is two, and the two clamping rods 24 are symmetrically arranged. By providing the clamping rods 24, the baffle 204 can be positioned and installed. Second support members 29 are fixedly connected to both the top and bottom of the power supply chassis body 4. A rotating shaft 28 is fixedly connected inside the second support member 29. A limiting member 21 is rotatably connected to the surface of the rotating shaft 28. By providing the limiting member 21, the position of the sliding plate 25 can be restricted.

[0033] Further, fixing plates 205 are fixedly connected to both sides of the baffle 204. A limiting groove is formed in the fixing plate 205, and a limiting plate 203 is inserted into the limiting groove. The limiting plate 203 is fixedly connected to the front surface of the power supply chassis body 4. By providing the limiting plate 203, the baffle 204 can be preliminarily limited.

[0034] Embodiment 2:

[0035] Refer to Figure 4 , and on the basis of Embodiment 1, it is further obtained that the buffer mechanism 3 includes positioning rods 33. The positioning rods 33 are fixedly connected to both sides of the power supply chassis body 4. A buffer plate 31 is slidably connected to the surface of the positioning rods 33. Both buffer plates 31 are arranged on both sides of the power supply chassis body 4. By providing the buffer plates 31, the power supply chassis body 4 can be protected.

[0036] Further, a mounting member 32 is fixedly connected to the side of the positioning rod 33 away from the power supply chassis body 4. The mounting member 32 is arranged inside the buffer plate 31. By providing the mounting member 32, the buffer plate 31 can be limited.

[0037] Furthermore, a second spring 34 is sleeved on the surface of the positioning rod 33. The second spring 34 is arranged on one side of the limiting member 21. Under the elastic potential energy of the second spring 34 itself, it can effectively buffer the external impact force, thereby playing a role in protecting the power supply chassis body 4.

[0038] During the actual operation process, when it is necessary to disassemble the baffle 204, the sliding plate 25 can be slid successively to make the clamping rod 24 disengage from the clamping groove formed inside the connecting plate 201. At this time, the sliding plate 25 squeezes the first spring 23, making the first spring 23 in a compressed state by itself. Then, by flipping the limiting member 21 towards the side close to the fixed rod 27, at this time, the limiting member 21 adheres to the left side of the fixed rod 27, which can limit the sliding plate 25 and prevent the clamping rod 24 from being clamped into the connecting plate 201 again. Then, by pulling the baffle 204 to make the limiting plate 203 disengage from the fixing plate 205, the purpose of disassembling the baffle 204 can be achieved. By setting the baffle 204 that is convenient for installation and disassembly, when the inside of the power supply chassis body 4 is damaged, the baffle 204 can be disassembled for maintenance, achieving the purpose of convenient maintenance;

[0039] When an external force impacts both sides of the power supply chassis body 4, under the impact generated by the external force, it will drive the buffer plate 31 to move towards the side close to the power supply chassis body 4, and make the second spring 34 in a compressed state. Under the elastic potential energy of the second spring 34 itself, it can effectively buffer the external impact force, thereby playing a role in protecting the power supply chassis body 4.

[0040] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to this process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.
