[0002] Polygonal distribution cabinets are generally composed of several cabinet panels and cabinet panel support frames. The shape of the cabinet panels is a regular polygon. Common polygonal distribution cabinets include quadrilaterals, pentagons, hexagons, etc. The number of sides of the polygon can be selected according to specific needs and designs. Different polygonal shapes may affect the structure, stability and space utilization of the distribution cabinet. When installing electronic components in the distribution cabinet, considering the limited internal space of the distribution cabinet, a detachable polygonal distribution cabinet has appeared.

[0003] The existing partially detachable polygonal distribution cabinet is divided into two detachable upper and lower cabinets. The upper and lower cabinets are fixedly connected by an adjustable connection structure. The upper cabinet can be removed by adjusting the connection structure to facilitate subsequent installation and maintenance work. However, its connection structure is too complicated. When the staff performs the disassembly work, they need to perform standardized operations step by step, and the work efficiency is low. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0033] See also Figure 1-8 The utility model is a detachable protective shell of a polygonal distribution cabinet, comprising a distribution cabinet shell 1 and a distribution cabinet shell 2. The distribution cabinet shell 1 is provided with a clamping assembly 3 on both opposite outer sides. The clamping assembly 3 comprises a pull piece 301. The pull piece 301 comprises an arc handle 302. A rotating shaft 303 is fixedly connected between the two ends of the arc handle 302. The rotating shaft 303 is rotatably matched with two symmetrical fixed plates 304 on the side surface. Two symmetrical cams 305 are fixed between the two fixed plates 304 on the side surface of the rotating shaft 303. The two cams 305 are slidably matched with driven rods 306 on the side surfaces. A spring 307 is movably sleeved on the side surface of the driven rod 306. A connecting plate 308 is fixed to the end of the driven rod 306 away from the cam 305. Two symmetrical L-shaped clamping plates 309 are fixed to the bottom of the connecting plate 308. The two L-shaped clamping plates 309 are movably clamped with the distribution cabinet shell 2.

[0034] Specifically, a plurality of clamping holes 201 are linearly provided on two inner sides of the second housing 2 of the power distribution cabinet.

[0035] The operation process of this embodiment is as follows: taking a quadrilateral distribution cabinet as an example, when inspecting the distribution cabinet, hold the arc handle 302 and rotate it around the fixed plate 304, so that the rotating shaft 303 fixedly connected to the arc handle 302 also rotates accordingly, and the rotating shaft 303 simultaneously drives the cam 305 fixed on its peripheral side to rotate, and the contour of the cam 305 drives the driven rod 306 to slide toward the inside of the distribution cabinet housing 1, and at the same time the spring 307 is compressed, and the driven rod 306 drives the connecting plate 308 fixed thereto to move, so that the two L-shaped clamping plates 309 fixed at the bottom of the connecting plate 308 are separated from the several clamping holes 201 corresponding to the inner side of the distribution cabinet housing 2, and then the arc handle 302 is pulled upward, so that the distribution cabinet housing 1 and the distribution cabinet housing 2 are quickly separated to provide a larger activity space, which is convenient for the staff to carry out maintenance work. Specific embodiment 2

[0037] See also Figure 1-8On the basis of the specific embodiment 1, specifically, one end of the driven rod 306 is a hemispherical body 310, and a ring 311 is fixedly connected to the side surface of the driven rod 306. Trapezoidal holes 101 are penetrated through the two opposite outer sides of the distribution cabinet housing 1, and the driven rod 306 is slidably matched with the trapezoidal hole 101. Blocks 105 are fixed to the two opposite outer sides of the distribution cabinet housing 1 below the trapezoidal hole 101, and arc-shaped grooves 106 are opened on the side surface of the block 105.

[0038] The operation process of this embodiment is as follows: when the power distribution cabinet is working, the arc handle 302 is stuck in the arc slot 106 of the block 105. When the power distribution cabinet housing needs to be disassembled, the arc handle 302 is pulled out of the arc slot 106;

[0039] The end of the driven rod 306 that contacts the contour of the cam 305 is set as a hemispherical body 310 to reduce the friction generated when the driven rod 306 contacts the contour of the cam 305. When the driven rod 306 slides in the trapezoidal hole 101, the ring 311 fixed on its peripheral side will squeeze the spring 307, so that the spring 307 will rebound and drive the driven rod 306 to reset. Specific embodiment three

[0041] See also Figure 1-8 On the basis of the specific embodiment 1 and the specific embodiment 2, specifically, the outer side of the distribution cabinet shell 1 is fixedly connected with a waterproof inclined plate 102, the bottom of the distribution cabinet shell 1 is fixed with a connecting frame 103, the inner side of the distribution cabinet shell 1 is provided with two symmetrical dovetail grooves 104, the top of the distribution cabinet shell 2 is fixed with a connecting frame 202, the inner side of the distribution cabinet shell 2 is provided with two symmetrical dovetail grooves 203, the distribution cabinet shell 1 and the distribution cabinet shell 2 are both provided with mounting components 4, the mounting components 4 include a slide rail 401 that is slidably fitted in the dovetail groove 104 and the dovetail groove 203, the slide rail 401 is provided with a slide groove 402, and a plurality of mounting plates 403 are slidably fitted in the slide groove 402, a side of the slide rail 401 is linearly provided with a plurality of fixed threaded holes 404, and the mounting plate 403 is provided with two symmetrical fixing holes 405 running through the inside.

[0042] The operation process of this embodiment is as follows: before the power distribution cabinet is disassembled, the connection frame 202 on the top of the power distribution cabinet housing 202 is inserted into the connection frame 103 at the bottom of the power distribution cabinet housing 103, and the waterproof inclined plate 102 on the outer side of the power distribution cabinet housing 102 is matched to prevent rainwater from entering the power distribution cabinet through the gap at the connection between the power distribution cabinet housing 101 and the power distribution cabinet housing 202;

[0043] When the switch cabinet housing 1 and the switch cabinet housing 2 are disassembled, since the slide rail 401 slides with the dovetail groove 104, after the disassembly, the slide rail 401 will be stuck in the dovetail groove 203. When inspecting the electronic components on each mounting plate 403, the bolts fixing the mounting plate 403 can be removed, and then the mounting plate 403 can be slid to a suitable position along the slide groove 402, and the mounting plate 403 can be fixed by using a suitable pin to pass through the fixing hole 405 and the corresponding fixing threaded hole 404 inside the mounting plate 403, so that the staff can perform the inspection work in a relaxed posture.
