However, in the traditional high -voltage switch operation trolley design, dial wheel usually adopts the circular structure with the diameter of 80mm. This circular dial wheel needs the operator to put the tiger mouth of hand on the outer circle of circular structure and force when rotating, which not only makes the rotating process difficult, especially for the person with smaller palm, more laborious. In addition, the design of circular dial wheel is not optimized in material use, and there is certain material waste problem.

[0003] Therefore, the person skilled in the art proposes a labor-saving high -voltage switch operation trolley dial wheel structure to solve the problem in the background art. SUMMARY

[0004] In order to solve the above technical problems, the utility model provides a labor-saving high -voltage switch operation trolley dial wheel structure, which realizes the effect of saving labor and material by improving the shape and structure of dial wheel, and improves the use convenience and economy of high -voltage switch operation trolley.

[0005] A labor-saving high -voltage switch operation trolley dial wheel structure, including support base, the top of support base is installed with the transport tray, the top of transport tray is provided with high -voltage switch, the support base is provided with connecting bolt between transport tray, the connecting bolt is installed at the top of support base, and the outer side wall of connecting bolt is connected with dial wheel.

[0006] Preferably, the dial wheel is an oval structure, compared with the traditional circular dial wheel structure, the oval structure saves material, and the oval dial wheel does not need to force the tiger mouth of hand on the outer circle of dial wheel when rotating.

[0007] Compared with the prior art, the utility model has the following beneficial effects:

[0008] 1, the oval dial wheel structure makes it unnecessary to force the tiger mouth of hand on the outer circle of dial wheel when rotating, and only needs to twist to easily dial the hand wheel, greatly reduces the operation difficulty and force requirement, realizes the effect of saving labor. This can effectively reduce the work burden and improve the work efficiency for the power workers who operate the high -voltage switch operation trolley for a long time.

[0013] The embodiment of the utility model is further described in detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but cannot be used to limit the scope of the utility model.

[0014] As shown in the accompanying Figure 1 To the accompanying Figure 3 As shown:

[0015] Example one: according to Figures 1-3 As shown, the utility model provides a labor-saving high voltage switch running trolley dial structure, including support base 1, the top of support base 1 is installed with shipping tray 2, the top of shipping tray 2 is provided with high voltage switch 3, connecting bolt 5 is arranged between support base 1 and shipping tray 2, connecting bolt 5 is installed at the top of support base 1, the outer side wall of connecting bolt 5 is threadedly connected with dial 4, dial 4 is oval structure, compared with the traditional circular (R=80mm) dial structure, oval (2a=80mm, 2b=46mm) structure saves material, and the oval dial does not need to be forced to place the tiger mouth of hand on the outer circle of dial when rotating;

[0016] The ratio of the major axis and the minor axis of the oval dial in the embodiment is 1.7:1, and through actual test, the ratio can realize the best labor-saving effect while guaranteeing the structural strength. The dial material selects high-strength ABS plastic, and is formed by injection molding machine equipment. The surface of the oval dial is provided with anti-skid texture to increase the friction force between the hand and the dial. In addition, the installation position and angle of the oval dial are accurately calculated to ensure that the height of the dial is consistent with the height of the circuit breaker room when the high voltage switch running trolley is sent into the high voltage switch cabinet circuit breaker room.

[0017] Working principle: when the device needs to be used, such as when it needs to be transported, first rotate the dial 4, make the dial 4 threadedly move outside the connecting bolt 5, make the dial 4 ascend against the shipping tray 2, achieve the purpose of adjusting the height of the shipping tray 2, and the dial 4 is oval, which is more convenient to rotate.
