The outer wall of the support wheel 232 is in contact with the inner wall of the box body 11, which can better position the mounting bracket 23 and reduce the friction between the mounting bracket 23 and the box body 11.

[0037] Refer to Figure 2 , at the top of the inner cavity of the mounting bracket 23, an installation groove 233 is provided vertically. The opening direction of the installation groove 233 is vertically downward; at the top of the mounting bracket 23, an adjustment groove 234 is provided horizontally. The long side direction of the adjustment groove 234 is parallel to the long side direction of the installation groove 233, and the inner cavity of the adjustment groove 234 is communicated with the inner cavity of the installation groove 233.

[0038] Refer to Figure 2 , each mounting bracket 23 is provided with a plurality of mounting devices 3. The mounting device 3 includes an adjustment block 31, a gripping portion 32, and a support rod 33. The adjustment block 31 is located in the adjustment groove 234, and the adjustment block 31 can slide along the long side direction of the adjustment groove 234.

In this embodiment, when the locking block 356 is located in the locking hole 346, at this time, the connection block 354 extends into the through groove and abuts against the support rod 33. A friction pad 357 is provided on the end face of the connection block 354 close to the support rod 33. Among them, the friction pad 357 has a certain deformation ability.

[0044] When the abutting plate 351 needs to be installed, the operator only needs to insert the connecting block 354 into the insertion slot 345 and make the locking block 356 located in the locking hole 346. The setting of the friction pad 357 can fix the abutting plate 351 to the mounting block 34 more stably.

In this embodiment, the support shaft 393 is preferably a circular shaft, and the support shaft 393 is perpendicular to the positioning plate 391, and the support shaft 393 and the clamping plate 353 are fixedly connected by screws.

[0054] The operator can place the component to be installed at the snap - on plate 353 and press the component downward. At this time, the component contacts the first chamfer of the clamping plate 372, causing the two clamping plates 372 to slide away from each other. The clamping plates 372 provide positioning on both sides of the component. Subsequently, the component abuts against the receiving plate 382. The edge of the receiving plate 382 is provided with a stepped shape. The component abuts against the stepped position of the receiving plate 382. Under the action of the second chamfer, the component can fit properly at the corresponding step, and then the receiving plate 382 supports the component from below. When the component reaches the appropriate position, rotate the snap - on plate 353, and the snap - on plate 353 completes the limit of the top of the component, thereby ensuring the stability of the component during installation and use.

[0055] Refer to Figure 2 and Figure 8 , a plurality of positioning devices 4 are installed at the support shaft 393, and the plurality of positioning devices 4 are arranged in sequence along the axis direction of the support shaft 393.

[0056] Refer to Figure 2 and Figure 8 , the positioning device 4 includes an installation rod 41. In this embodiment, the installation rod 41 is preferably a rectangular rod. The installation rod 41 is sleeved on the support shaft 393 and is rotatably connected to the support shaft 393 by means of a bearing connection. The installation rod 41 is provided with a sliding groove 42. Among them, the opening direction of the sliding groove 42 is parallel to the axis direction of the support shaft 393, and the long - side direction of the sliding groove 42 is parallel to the long - side direction of the installation rod 41.

[0057] Refer to Figure 2 and Figure 8 , the inner cavity of the sliding groove 42 is provided with a plurality of support blocks 43, and the support blocks 43 can slide along the long - side direction of the sliding groove 42. The support blocks 43 are provided with accommodation holes 431 in a penetrating manner. The axis direction of the accommodation holes 431 is parallel to the axis direction of the support shaft 393. The support blocks 43 are coaxially provided with fixing grooves 432 in the accommodation holes 431. In this embodiment, both the accommodation holes 431 and the fixing grooves 432 are selected as circular holes.

[0058] When the operator performs wiring operations on related components, only need to rotate the installation rod 41 along the support shaft 393, and then make the support block 43 slide along the sliding groove 42, so that the support block 43 reaches the relevant position of the component, and pass the wire through the accommodation hole 431, thereby completing the positioning of the position of the wire, preventing the wire from shaking, and further affecting the connection stability between the wire and the component.

[0059] Refer to Figure 8 and Figure 9, a positioning ring 44 is provided at the top of the receiving hole 431. In this embodiment, the positioning ring 44 is preferably a circular ring, and the positioning ring 44 is horizontally arranged. The positioning ring 44 and the receiving cylinder are coaxially arranged. A plurality of protrusions are evenly distributed on the outer wall of the positioning ring 44, and both ends of the protrusions are fixedly connected to the positioning ring 44 and the support block 43 respectively.

[0060] The setting of the positioning ring 44 further limits the position of the circuit, and further ensures that the circuit remains vertical during the connection with the component, which can better improve the connection stability between the circuit and the component.

[0061] Refer to Figure 9 , a plurality of limiting grooves 433 are provided on the bottom wall of the fixing groove 432 of the support block 43. In this embodiment, the number of the limiting grooves 433 is preferably four, and the four limiting grooves 433 are circumferentially evenly distributed along the axial direction of the limiting grooves 433. The limiting grooves 433 are preferably arc-shaped grooves, and the four limiting grooves 433 jointly enclose a circular ring.

[0062] Refer to Figure 10 , Figure 11 and Figure 12 , each limiting groove 433 is provided with a contact member 45. The contact member 45 includes a slider 451, a second spring 452, a fixed tube 453, a guide block 454, a contact rod 455, a third spring 456 and a fourth spring 457. The slider 451 is located in the limiting groove 433, and the slider 451 reciprocates along the limiting groove 433 through an elastic member. The telescopic direction of the second spring 452 is parallel to the long side direction of the limiting groove 433. Both ends of the second spring 452 are fixedly connected to the support block 43 and the slider 451 respectively. The axial direction of the fixed tube 453 is the radial direction of the receiving hole 431. A directional groove is provided on the bottom wall of the fixed tube 453, and the long side direction of the directional groove is parallel to the axial direction of the fixed tube 453. The guide block 454 is located on the top wall of the fixed tube 453, and the top wall of the guide block 454 is attached to the top wall of the fixing groove 432. The fixed tube 453 and the guide block 454 are fixedly connected. The contact rod 455 passes through the inner cavity of the fixed tube 453 and can slide along the axial direction of the fixed tube 453. The third spring 456 is located in the inner cavity of the fixed tube 453, and both ends of the third spring 456 are fixedly connected to the fixed tube 453 and the contact rod 455 respectively. The slider 451 extends into the directional groove. The fourth spring 457 is located in the directional groove, and the telescopic direction of the fourth spring 457 is parallel to the directional groove. Both ends of the fourth spring 457 are fixedly connected to the slider 451 and the support block 43 respectively.

[0063] After the operator passes through the positioning ring 44, the contact rod 455 is squeezed, so that the contact rod 455 can slide along the fixed tube 453, so that the end of the contact rod 455 can better contact the circuit, and further can better limit the circuit and prevent the circuit from displacing during the connection process.

[0064] Reference Figure 10 、 Figure 11 and Figure 12 At one end of the abutting rod 455 away from the fixed pipe 453, there are two rotating parts 46. The two rotating parts 46 are symmetrically arranged in the vertical direction. The rotating part 46 is rotatably connected to the abutting rod 455 by means of a torsion spring. The rotation axis of the rotating part 46 is vertical. In this embodiment, a third chamfer is provided at the top of the rotating part 46.

[0065] Reference Figure 10 、 Figure 11 and Figure 12 On the end face of each rotating part 46 close to the axis of the rotating accommodation hole 431, there is an abutting wheel 47. The rotation axis of the abutting wheel 47 is horizontal, and an elastic pad is provided on the surface of the abutting wheel 47. A large number of anti-slip lines are provided on the surface of the elastic pad.

[0066] The setting of the rotating part 46, and the rotating part 46 can rotate along the abutting rod 455, so that the rotating part 46 can better fit the side wall of the line, further improving the limiting effect of the abutting rod 455 on the line. The abutting wheel 47 can reduce the friction effect between the line and the abutting rod 455 to a certain extent. The setting of the elastic pad can enable the abutting wheel 47 to better clamp the line. At the same time, the setting of the anti-slip lines can prevent the line from sliding along the abutting wheel 47 after being fixed, affecting the connection stability of the line.

[0067] Reference Figure 10 、 Figure 11 and Figure 12 Each guiding block 454 is provided with a reset member 48. The reset member 48 is installed in the fixing groove 432 and is located at the top of the fixed pipe 453. The guiding block 454 always fits against the side wall of the reset member 48. In this embodiment, the horizontal cross-section of the end face where the guiding block 454 fits against the reset member 48 is preferably a spiral surface. As the fixed pipe 453 rotates, the distance between the guiding block 454 and the axis of the accommodation hole 431 gradually increases. One end of the reset member 48 close to the axis of the accommodation hole 431 is arc-shaped, and a serrated cross-section is provided at the arc surface. In this embodiment, the average distance between adjacent wave crests and wave troughs to the axis of the accommodation hole 431 is the same.

[0068] When the circuit needs to be adjusted or removed, since the abutting wheel 47 and the rotating part 46 provide limit for the circuit, at this time, the operator only needs to rotate the circuit to drive the abutting rod 455 and the fixed pipe 453 to rotate along the limit groove 433. The guiding block 454 is limited by the reset part 48 until the guiding block 454 reaches the serrated part of the reset part 48. At this time, the fixed pipe 453 will generate a certain vibration, so that the fixed pipe 453 slides radially along the receiving hole 431, driving the rotating part 46 and the abutting wheel 47 away from the circuit, releasing the limit on the circuit. At this time, the operator quickly takes out the circuit, and at the same time, the third spring 456 drives the slider 451 to return to its original position, that is, the fixed pipe 453 and the abutting rod 455 slowly return to the initial position, facilitating the operator to perform subsequent related operations.

[0069] The implementation principle of a quick connection device for a quick distribution cabinet is as follows: First, the operator moves the box body 11 to a suitable position, then slides the support plate 221 along the long side direction of the track part 21 to a suitable position, and then rotates the connecting rod 224 so that the first cam 225 can abut against the box body 11, thereby completing the fixation of the position of the support plate 221, and further completing the fixation of the position of the mounting bracket 23. At the same time, the setting of the support wheel 232 can ensure that the mounting bracket 23 is in a vertical state and reduce the friction between the mounting bracket 23 and the box body 11.

[0070] Subsequently, through the holding part 32, the position of the sliding adjustment block 31 is adjusted. According to the quantity and position of the components to be installed, an appropriate number of mounting blocks 34 are installed, and then the mounting blocks 34 are slid to a suitable position. During the sliding process, the maximum stroke of the second cam 344 does not contact the support rod 33. When reaching the suitable position, the mounting blocks 34 are slid in the reverse direction, and the maximum stroke of the second cam 344 contacts the support rod 33, then the fixation of the position of the mounting blocks 34 can be completed.

[0071] After reaching the suitable position, press the connection block 354 so that the connection block 354 can abut in the insertion slot 345, and at the same time, make the locking block 356 located in the locking hole 346 to complete the fixation of the positions of the mounting block 34 and the abutting plate 351.

[0072] Subsequently, the operator installs the components to be installed, positions both sides of the components through the clamping plates 372 on both sides, supports the bottom of the components through the receiving plate 382, and rotates the positioning plate 391 to complete the positioning of the components.

[0073] The heat energy generated by the related electrical appliances will first pass through the fourth heat dissipation groove 3531 through the clamping plate 353, and then the heat enters the second heat dissipation groove 3521. Along with the flow of the second heat dissipation groove 3521, it enters the fourth heat dissipation groove 3531 through the third heat dissipation groove 3522, and then leaves the abutting plate 351. At the same time, the first heat dissipation groove 3511, the second heat dissipation groove 3521, the third heat dissipation groove 3522, and the fourth heat dissipation groove 3531 can increase the heat dissipation area and improve the heat dissipation speed.

[0074] When installing the related circuit, the operator only needs to rotate the installation rod 41 along the support shaft 393, and then slide the support block 43 so that the receiving hole 431 of the support block 43 communicates with the wiring hole of the component. Slide the circuit along the receiving hole 431, first pass through the positioning ring 44, and then abut against the rotating part 46 and the abutting wheel 47. During this process, the abutting wheel 47 can reduce the friction between the rotating part 46 and the circuit to a certain extent, ensuring the smooth passage of the circuit. When the circuit is installed in place, position the circuit and the component.

[0075] When the circuit needs to be loosened, the operator only needs to rotate the circuit. At this time, the circuit is limited by the rotating part 46, and then drives the abutting rod 455 and the fixed tube 453 to rotate together. At this time, the guide block 454 and the reset part 48 are released until the abutting block contacts the serrated part of the reset part 48. At this time, the fixed tube 453 reaches the position farthest from the axis of the receiving hole 431. At this time, the rotating part 46 no longer contacts the circuit and the limiting effect is released. Then the operator can easily withdraw the circuit from the receiving hole 431. After withdrawal, under the action of the third spring 456 and the fourth spring 457, the fixed tube 453 and the abutting rod 455 return to the initial position, providing support for the operator to perform subsequent operations.
