DETAILED DESCRIPTION

[0019] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0020] The embodiment of the present application discloses a height-adjustable protection shed for a power distribution cabinet. Figure 1 A height-adjustable distribution cabinet protection shed includes a top cover 1 and four columns 21 arranged around the top cover 1. The upper ends of the columns 21 are slidably arranged with support rods 22 arranged along the length direction thereof. The four corners of the top cover 1 are respectively fixedly connected to the tops of the four support rods 22. Specifically, the columns 21 and the support rods 22 can be square tubes or round tubes, which are plugged into each other. A railing 23 is fixedly connected between the top ends of two adjacent columns 21, and a guardrail (not shown in the figure) or a fence gate 25 is arranged between two adjacent columns 21, one railing 23 corresponds to one fence gate 25, and the other three railings 23 correspond to three guardrails respectively; a cross bar 3 is rotatably arranged between the two railings 23 close to the fence gate 25, a vertical pole 11 is vertically fixedly connected to the middle part of the lower end surface of the top cover 1, and a guide frame 33 is fixedly connected between the two railings 23 connecting the cross bar 3, the vertical pole 11 passes through the guide frame 33 and rises and slides on the guide frame 33, and an adjustment mechanism is arranged between the vertical pole 11 and the cross bar 3 for driving the vertical pole 11 to rise and fall and lock when the cross bar 3 is rotated.

[0021] In this way, when assembling the distribution cabinet protection shed, first fix the four corners of the top cover 1 to the tops of the four support rods 22 respectively, and then insert the four support rods 22 into the upper ends of the four columns 21 respectively; secondly, fix the railings 23 to the tops of the two adjacent columns 21, fix the guardrails and the balustrade gates between the columns 21 accordingly, and fix the columns 21 in the required positions. When it is necessary to adjust the height of the top cover 1 of the distribution cabinet protection shed, the cross bar 3 can be rotated and the vertical pole 11 can be driven to rise and fall through the adjustment mechanism. The vertical pole 11 drives the top cover 1 to rise and fall when it rises and falls. In this process, the guide frame 33 can guide the vertical pole 11, and the four support rods 22 can rise and fall on the corresponding four columns 21, so that the top cover 1 can be raised and lowered smoothly, and only one operator is required for operation, which greatly saves manpower and improves the convenience of the lifting and adjustment of the top cover 1. Then, the lever 411 is pushed to disengage the outer gear ring 42 from the inner gear ring 41, and at the same time, the handle 32 is turned to rotate the cross bar 3 to drive the vertical pole 11 to rotate and adjust the height of the distribution cabinet protection shed. Finally, the lever 411 is released, and the inner gear ring 41 and the outer gear ring 42 are engaged with each other under the deformation of the elastic member 43 to lock the height of the top cover 1. The overall operation is convenient and manpower is saved.

[0022] Specifically, the adjustment mechanism includes a meshing rack 12 and a gear 31 , wherein the rack 12 is fixed to the vertical rod 11 along the length direction of the vertical rod 11 , and the gear 31 is coaxially fixed to the crossbar 3 ; and also includes a locking assembly for locking the crossbar 3 .

[0023] Furthermore, the locking assembly includes an inner gear ring 41 sleeved on the cross bar 3, the inner gear ring 41 is slidably arranged on the corresponding railing 23 along the length direction of the cross bar 3, and an outer gear ring 42 is coaxially fixed to the cross bar 3 and meshes with the inner gear ring 41.

[0024] An elastic member 43 is connected between the inner gear ring 41 and the adjacent railing 23. One end of the elastic member 43 is fixedly connected to the inner gear ring 41, and the other end is fixedly connected to the adjacent railing 23. When the inner gear ring 41 and the outer gear ring 42 are disengaged, the elastic member 43 is in a deformed state. The elastic member 43 is specifically a spring sleeved on the cross bar 3.

[0025] One end of the cross bar 3 protrudes from the outer edge of the railing 23, and the inner gear ring 41 and the outer gear ring 42 are arranged on one side of the protruding end of the cross bar 3. At least two guide rods 44 fixed to the railing 23 are passed through the outer side of the inner gear ring 41, so that the inner gear ring 41 can only slide along the length direction of the cross bar 3.

[0026] In this way, when adjusting the height of the top cover 1, the inner gear ring 41 can be pushed so that the inner gear ring 41 is disengaged from the outer gear ring 42. At this time, the outer gear ring 42 and the cross bar 3 can rotate freely on the railing 23. When the cross bar 3 is rotated, the gear 31 on the cross bar 3 rotates and drives the rack 12 meshed with it to rise and fall, thereby making the vertical rod 11 rise and fall on the guide frame 33, so that the height of the top cover 1 can be freely adjusted. When the height adjustment of the top cover 1 is completed, the external force applied to the inner gear ring 41 is released, and the inner gear ring 41 moves toward the direction close to the outer gear ring 42 under the action of the deformation force of the elastic member 43, and finally keeps meshing with the outer gear ring 42. At this time, the inner gear ring 41 locks the outer gear ring 42, so that the cross bar 3 cannot rotate relative to the inner gear ring 41, and the setting of multiple guide rods 44 limits the rotational movement of the inner gear ring 41, so that the cross bar 3 is locked and cannot rotate, thereby achieving the locking effect after the top cover 1 is raised and lowered.

[0027] In order to further facilitate the adjustment and locking of the height of the distribution cabinet protection shed, a handle 32 is fixedly connected to the end of the cross bar 3, and a lever 411 is fixedly connected to the outer peripheral wall of the inner gear ring 41. The lever 411 can facilitate the pushing of the inner gear ring 41, and the handle 32 can be used to more effortlessly rotate the cross bar 3, so as to reduce the difficulty of adjusting the height of the top cover 1.

[0028] In addition, a plurality of rubber rings (not shown in the figure) are arranged between the support rod 22 and the column 21 to improve the smoothness of the relative sliding between the two.

[0029] The implementation principle of a height-adjustable distribution cabinet protection shed in the embodiment of the present application is as follows:

[0030] When it is necessary to adjust the height of the top cover 1 of the distribution cabinet protection shed, the meshing of the inner gear ring 41 and the outer gear ring 42 can be released first, and then the cross bar 3 can be rotated with the help of the handle 32 to drive the vertical pole 11 to rise and fall through the meshing of the gear 31 and the rack 12. The vertical pole 11 drives the top cover 1 to rise and fall when it is raised and lowered. In this process, the guide frame 33 can guide the vertical pole 11, and the four support rods 22 can rise and fall on the corresponding four columns 21, so that the top cover 1 can be raised and lowered smoothly, and only one operator is required for the operation, which greatly saves manpower and improves the convenience of the lifting and lowering adjustment of the top cover 1.
