DETAILED DESCRIPTION

[0022] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0023] The switch assembly and disassembly parts of the power distribution cabinet according to the embodiment of the utility model are described below in conjunction with the accompanying drawings.

[0024] like Figure 1-Figure 6 As shown, the switch disassembly component of the power distribution cabinet according to the embodiment of the utility model may include a housing 10 , a stop block 20 , a rotating rod 30 and a quick-release head 40 .

[0025] A mounting hole 11 penetrating vertically is formed on one side of the housing 10 .

[0026] It is understandable that the housing 10 can be disposed on the card slot on the back of the switch 50 of the distribution cabinet, and the switch 50 of the distribution cabinet can be connected to the guide rail 60 through the card slot. The stopper 20 is disposed in the card slot, and the guide rail 60 can be stuck in the first groove 21.

[0027] A mounting hole 11 which passes through the housing 10 from top to bottom is formed on one side of the housing 10. A spring 12 and a rotating drum 13 which are connected in sequence are arranged in the mounting hole 11. The rotating drum 13 passes through the housing 10 from top to bottom, and a thread 131 and a channel 132 for the movement of the rotating rod 30 are arranged on the inner wall of the rotating drum 13. The head and tail ends of the thread 131 are respectively arranged on both sides of the channel 132 from top to bottom.

[0028] A first groove 21 is provided on one side of the stop block 20 , and a connecting rod 22 is provided on the other side of the stop block 20 . The connecting rod 22 penetrates the spring 12 and is movably connected to the rotating rod 30 . The other end of the spring 12 contacts the stop block 20 .

[0029] A slider 31 is disposed on the rotating rod 30 . The slider 31 is rotatably disposed on the thread 131 . The other end of the rotating rod 30 passes through the mounting hole 11 and is connected to the quick-release head 40 .

[0030] It should be noted that the quick-release head 40 described in this embodiment is provided with a through hole 41. The provided through hole 41 helps relevant personnel to use tools (such as a screwdriver, etc.) to perform a pull-out operation on the disassembly head.

[0031] Specifically, when the distribution cabinet switch 50 needs to be installed on the guide rail 60, the relevant personnel first press one side of the guide rail 60 against the first groove 21, and then press the other side of the distribution cabinet switch 50 down to the slot behind it to clamp it on the guide rail 60. During the process, the distribution cabinet switch 50 squeezes the block 20, so that the block 20 drives the quick-release head 40 to move relative to the housing 10. During the process, the block 20 squeezes the spring 12, the rotating rod 30 moves in the rotating cylinder 13, and the slider 31 moves in the channel 132. At this time, the spring 12 has a certain resilience on the block 20, and there is still a gap between the block 20 and the guide rail 60, so that the distribution cabinet switch 50 can move on the guide rail 60, which helps the relevant personnel to adjust the position of the distribution cabinet switch 50.

[0032] After the relevant personnel determine the position of the distribution cabinet switch 50 on the guide rail 60, the quick release head 40 can be rotated so that the quick release head 40 drives the rotating rod 30 to rotate. During the process, the slider 31 rotates from the lower end of the thread 131 on the channel 132 into the thread 131 until the slider 31 moves to the high end of the thread 131. During the process, as the rotating rod 30 rotates, the rotating rod 30 moves together with the stop block 20 in the direction of the guide rail 60, and during the process, the rotating rod 30 rotates relative to the connecting rod 22, and the connecting rod 22 drives the stop block 20 to move and abut against the guide rail 60 under the action of the rotating rod 30, thereby fixing the distribution cabinet switch 50.

[0033] When the switch 50 of the distribution cabinet needs to be removed, first rotate the quick-release head 40 so that the quick-release head 40 drives the slider 31 to rotate, so that the slider 31 enters the channel 132 from the high end of the thread 131. At this time, the slider 31 moves toward the quick-release head 40 in the channel 132, and the stop block 20 is separated from the guide rail 60. Then, the stop block 20 can be pulled out through the quick-release head 40 to release the contact between the stop block 20 and the guide rail 60, so that the two are separated, and the switch 50 of the distribution cabinet can be easily removed.

[0034] In one embodiment of the present invention, Figure 6As shown, a plurality of damping members 14 are arranged on the inner circumference of the mounting hole 11, and a plurality of second grooves 32 are arranged on the outer circumference of the rotating rod 30. The plurality of damping members 14 are slidably arranged in the corresponding second grooves 32, respectively. The second grooves 32 are arranged adjacent to the quick-release head 40, and the second grooves 32 extend along the connecting rod 22 and are arranged in a long strip shape.

[0035] It can be understood that the damping member 14 can provide a certain resistance when the disassembly head rotates, which is beneficial to the stability of the switch 50 of the distribution cabinet after installation.

[0036] In one embodiment of the present invention, Figure 6 As shown, a third groove 221 is provided on one side of the connecting rod 22, and the third groove 221 is T-shaped. An embedding portion 33 matching the third groove 221 is provided at one end of the rotating rod 30, and the embedding portion 33 can be slidably embedded in the third groove 221.

[0037] It can be understood that when the rotating rod 30 rotates relative to the connecting rod 22 , the embedded portion 33 slides and rotates in the third groove 221 , which helps to make the positions of the rotating rod 30 and the connecting rod 22 relatively stable.

[0038] In summary, the switch disassembly and assembly part of the power distribution cabinet in the embodiment of the utility model can realize two connection conditions between the switch and the guide rail, which can not only allow the switch to slide on the guide rail, but also fix it. This flexibility enables the switch to adapt to various situations and helps to improve the efficiency of switch installation.
