[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1 , Figure 2 , Figure 3As shown, the utility model provides a power cabinet that is easy to disassemble and assemble, including a power cabinet body 1, the power cabinet body 1 is connected to each other front and back, a power cabinet fixing mechanism 2 is arranged on the rear side of the power cabinet body 1, a movable door 3 is movably installed on the right side of the front end of the power cabinet body 1, a limited position frame 12 is fixedly installed on the rear side of the inner circle of the power cabinet body 1, a fixing mechanism groove 13 is opened in the middle of the left and right sides of the rear end of the power cabinet body 1, a fixing mechanism 14 is arranged inside the fixing mechanism groove 13, a clamping mechanism groove 15 is opened in the middle of the upper and lower sides of the rear end of the power cabinet body 1, a clamping mechanism 16 is arranged inside the clamping mechanism groove 15, and the power cabinet body 1 is provided with a plurality of clamping mechanisms. Positioning slides 11 are provided on both the left and right sides of the bottom of the cabinet body 1, and the power cabinet fixing mechanism 2 includes a power cabinet separation rear plate 21, and a plurality of equipment mounting frames 22 are fixedly installed on the front side of the power cabinet separation rear plate 21, and two positioning sockets 23 are provided in the middle of the left and right sides of the power cabinet separation rear plate 21, and an L-shaped base 24 is fixedly installed at the lower rear side of the power cabinet separation rear plate 21, and positioning slides 25 are fixedly installed on both the left and right sides of the top of the horizontal part of the L-shaped base 24, and the two positioning slides 25 are respectively slidably connected with the two positioning slides 11, and the power cabinet separation rear plate 21 is clamped with the rearmost side of the inner circle of the power cabinet body 1;

[0021] When installing the frame-type power cabinet case 1, the positioning groove 11 at the bottom of the power cabinet case 1 is aligned with the two positioning slide bars 25 at the top of the L-shaped base 24 at the bottom of the power cabinet separation rear plate 21, and the separation plate 21 of the entire power cabinet is inserted into the rear side of the inner circle of the power cabinet case 1 and stops when it contacts the limit frame 12 on the rear side of the inner circle of the power cabinet case 1. Because the equipment is installed on the front side of the entire power cabinet separation rear plate 21, when the power cabinet case 1 is disassembled and pulled out, the separation rear plate 21 of the power cabinet can remain stable by using its own weight and the L-shaped base 24 contacting the ground.

[0022] like Figure 4 As shown, the two fixing mechanisms 14 each include a fixed drive box 141, and the two fixed drive boxes 141 are respectively fixedly installed in the two fixing mechanism grooves 13, and the inner walls of the two fixed drive boxes 141 are movably installed with threaded rods 142 in the middle of one side close to the separated rear plate 21 of the power cabinet, and the other ends of the two threaded rods 142 respectively penetrate into the opposite back sides of the two fixed drive boxes 141 and are fixedly installed with control knobs 143, and the outer walls of the two threaded rods 142 are threadedly installed with movable plates 144, and the upper and lower sides of the opposite surfaces of the two movable plates 144 are fixedly installed with positioning rods 145, and the two positioning rods 145 included in the two fixed drive boxes 141 respectively penetrate into the opposite surfaces of the two fixed drive boxes 141 and are clamped with the positioning sockets 23 on the left and right sides of the separated rear plate 21 of the power cabinet;

[0023] By rotating the control knobs 143 on the back of the fixed drive boxes 141 in the two fixing mechanism slots 13 on the left and right sides of the rear end of the power cabinet body 1, the threaded rods 142 in the inner cavities of the two fixed drive boxes 141 are driven to rotate, and the two positioning rods 145 can be gradually moved toward the separated rear plate 21 of the power cabinet by using the threaded connection between the moving plate 144 and the threaded rods 142, until they are stuck in the positioning plug holes 23 on the left and right sides of the separated rear plate 21 of the power cabinet, so as to complete the fixing of the separated rear plate 21 of the power cabinet, so that the separated rear plate 21 of the power cabinet and the power cabinet are fixed. The box body 1 is assembled as a whole. When it needs to be disassembled, it is only necessary to rotate the control knobs 143 contained in the two fixed drive boxes 141 in the opposite direction to reverse the threaded rod 142, so that the movable plate 144 can drive the two positioning rods 145 to disengage from the positioning socket 23, thereby releasing the limit on the separated rear plate 21 of the power cabinet. Then, the entire power cabinet box body 1 is pulled to the front side, and the power cabinet box body 1 can be removed, and the equipment installed on the equipment mounting frame 22 on the front side of the separated rear plate 21 of the power cabinet can be completely exposed, so as to facilitate all-round and rapid maintenance work.

[0024] like Figure 5 As shown, the two clamping mechanisms 16 each include a clamping box 161, and the two clamping boxes 161 are respectively fixedly installed in the upper and lower clamping mechanism grooves 15, and a plurality of compression springs 162 are fixedly installed on the inner wall of the two clamping boxes 161 away from the inner circle of the power cabinet body 1, and a buckle bottom plate 163 is fixedly installed on the opposite ends of the plurality of compression springs 162 in the inner circle of the two clamping boxes 161, and an inclined buckle 164 is fixedly installed on the opposite surfaces of the two buckle bottom plates 163, and the horizontal opposite ends of the two inclined buckles 164 respectively penetrate the opposite surfaces of the two clamping boxes 161 and are provided with damping grooves 165, and the tops of the two damping grooves 165 are fixedly installed with damping rubber strips 166;

[0025] When the separated rear plate 21 of the power cabinet is inserted into the inner circle of the rear side of the power cabinet case 1, the inclined surfaces of the inclined snap fasteners 164 on the opposite sides of the clamping box 161 in the clamping mechanism grooves 15 on the upper and lower sides of the rear end of the power cabinet case 1 are squeezed, thereby causing the inclined snap fasteners 164 to drop and use the snap fastener bottom plate 163 to compress a plurality of compression springs 162. The pressure generated by the compression springs 162 can cause the damping rubber strips 166 at the horizontal top ends of the two inclined snap fasteners 164 to clamp the upper and lower sides of the separated rear plate 21 of the power cabinet, thereby allowing the power cabinet case 1 to be temporarily connected to the separated rear plate 21 of the power cabinet in a relatively stable manner.

[0026] The following is a detailed description of the working principle of this conveniently disassembled power cabinet.

[0027] like Figure 1-5As shown, when installing the frame-type power cabinet body 1, the positioning slide groove 11 at the bottom of the power cabinet body 1 is aligned with the two positioning slide bars 25 at the top of the L-shaped base 24 at the bottom of the power cabinet separation rear plate 21, and the entire power cabinet separation rear plate 21 is inserted into the rear side of the inner circle of the power cabinet body 1 and stops when it abuts against the limit frame 12 at the rear side of the inner circle of the power cabinet body 1. At the same time, when it is inserted, the inclined surfaces of the opposite sides of the clamping box 161 in the clamping mechanism grooves 15 on the upper and lower sides of the rear end of the power cabinet body 1 are also pressed. The inclined surface of the buckle 164 is squeezed, so that the inclined buckle 164 is lowered and the buckle bottom plate 163 is used to compress the plurality of compression springs 162. The pressure generated by the compression springs 162 can make the damping rubber strips 166 at the top level of the two inclined buckles 164 clamp the upper and lower sides of the power cabinet separation rear plate 21, so that the power cabinet box body 1 is temporarily clamped with the power cabinet separation rear plate 21 more stably, and then the two fixing mechanism slots 13 on the left and right sides of the rear end of the power cabinet box body 1 can be rotated. The control knobs 143 on the back of the inner fixed drive box 141 drive the threaded rods 142 in the inner cavities of the two fixed drive boxes 141 to rotate, and the two positioning rods 145 can be gradually moved toward the separated rear plate 21 of the power cabinet by using the threaded connection between the movable plate 144 and the threaded rod 142, until they are stuck in the positioning holes 23 on the left and right sides of the separated rear plate 21 of the power cabinet, so as to complete the fixation of the separated rear plate 21 of the power cabinet, so that the separated rear plate 21 of the power cabinet and the power cabinet body 1 are completely combined. When disassembly is required, it is only necessary to rotate the control knobs 143 contained in the two fixed drive boxes 141 in the opposite direction to reverse the threaded rod 142, so that the movable plate 144 can drive the two positioning rods 145 to disengage from the positioning holes 23, release the limit on the separated rear plate 21 of the power cabinet, and then pull the entire power cabinet body 1 to the front side, so that the power cabinet body 1 can be removed, and the equipment installed on the equipment mounting frame 22 on the front side of the separated rear plate 21 of the power cabinet can be completely exposed, so as to facilitate all-round and rapid maintenance work.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
