[0037] In order to enable those skilled in the art to more fully understand the technical solutions of the present utility model, the exemplary embodiments of the present utility model will be described more comprehensively and in detail below with reference to the accompanying drawings. Obviously, one or more of the embodiments of the present utility model described below are only one or more of the specific ways to implement the technical solutions of the present utility model, and are not exhaustive. It should be understood that other ways belonging to a general inventive concept of the present utility model can be used to implement the technical solutions of the present utility model, and should not be limited by the exemplary embodiments described. Based on one or more embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present utility model.

[0038] Embodiment: Figure 1 The structural schematic diagram of the power control switch of an engineering vehicle according to an embodiment of the present utility model is shown; Figure 2 The structural schematic diagram of the limit mechanism according to an embodiment of the present utility model is shown.

[0039] Refer to Figure 1-2, an embodiment of the present utility model provides a power control switch for an engineering vehicle, including a power control switch main body and a limiting mechanism;

[0040] A fixed cover 1 and a movable cover 2 for adjusting the power control switch main body to an on or off state are provided on the power control switch main body. The fixed cover 1 has a first connecting handle 11. The movable cover 2 is connected to the fixed cover 1 and has a second connecting handle 21 thereon. Connecting holes 3 are provided in both the first connecting handle 11 and the second connecting handle 21;

[0041] The limiting mechanism includes a connecting component and a buckle body 4. The connecting component includes a connecting plate 5 inserted into the connecting hole 3 of the first connecting handle 11. One end of the buckle body 4 is hinged to one end of the connecting plate 5, and the other end is configured to be connectable to the other end of the connecting plate 5 along the outside of the first connecting handle 11;

[0042] When the power control switch main body 1 is in the on state, the second connecting handle 21 is sleeved on the connecting plate 5 and can be limited by the buckle body 4.

[0043] In one embodiment, the power control switch main body 1 further includes a terminal post 6 for connecting the power supply equipment of the engineering vehicle. Specifically, the power control switch main body further includes a contact component connected to the movable cover. When the movable cover is rotated so that the electrode plates in the contact component are in contact, the terminal post is electrically connected to the power supply equipment. Otherwise, there is no current passing through the terminal post, and there is no power supply for the engineering vehicle. The working principle of the power control switch main body is prior art, such as the main power switch, and will not be elaborated here.

[0044] In one embodiment, the connecting component further includes a first mounting plate 7 and a second mounting plate 8 provided on one side of the first connecting handle 11 and a connecting shaft 9 connecting the first mounting plate 7 and the second mounting plate 8. One ends of the connecting plate 5 and the buckle body 4 are both sleeved on the connecting shaft 9.

[0045] Specifically, when the power control switch main body is in the on state, the second connecting handle fits with the first connecting handle, and one end of the buckle body is connected to the connecting plate along the outside of the two to limit the second connecting handle, thereby effectively preventing the occurrence of incorrect operations by the driver.

[0046] In a specific embodiment, the buckle body 4 is an arc-shaped structure made of nylon material.

[0047] In one embodiment, a through groove 41 for connecting with the connecting plate 5 is provided at one end of the buckle body 4.

[0048] In one embodiment, a limiting block 51 for connecting with the buckle body 4 is provided at one end of the connecting plate 5, and the limiting block 51 is configured to be able to rotate axially.

[0049] In a specific embodiment, the size of the limiting block 51 is smaller than that of the through groove 41.

[0050] When the power control switch of the present utility model is in use, when it is necessary to turn on the power control switch main body, the driver can rotate the movable cover so that the second connecting handle is sleeved on the connecting plate through the connecting hole thereon, and then connect the buckle body to the connecting plate along the outer sides of the first connecting handle and the second connecting handle, and fix it through the through groove and the limiting block. When it is necessary to turn off the power control switch main body, the above operations can be repeated in reverse.

[0051] The power control switch of the engineering vehicle proposed by the present utility model is provided with a connecting plate in the connecting hole of the first connecting handle, and one end of the buckle body is hinged to one end of the connecting plate, and the other end thereof is configured to be able to be connected to the other end of the connecting plate along the outer side of the first connecting handle, so that when the power control switch main body is in the on state, the second connecting handle is sleeved on the connecting plate and can be limited by the buckle body.

[0052] Furthermore, through the arrangement of the through groove and the limiting block, it is convenient for the connection and separation of the buckle body and the connecting plate, so as to facilitate the operation of the driver.

[0053] Therefore, compared with the existing power control switch of the engineering vehicle, the power control switch of the present utility model can limit the movable cover for adjusting the power control switch main body to be in the on or off state by limiting the second connecting handle, so as to effectively prevent the driver from making wrong operations during driving, and further ensure the safety of construction.

[0054] Although the above describes one or more embodiments of the present utility model, those of ordinary skill in the art should know that the present utility model can be implemented in any other form without departing from its gist and scope. Therefore, the above-described embodiments are illustrative rather than restrictive, and many modifications and substitutions are obvious to those of ordinary skill in the art without departing from the spirit and scope of the present utility model as defined by the appended claims.
