One end of the connecting rod 7 passes through the arc-shaped limiting tube 4 through the limiting rod 5, so that when the power switch body 1 is in the on state, the limiting rod 5 can lock the control handle 3 through the connecting rod 7.

[0039] In one embodiment, a terminal post 8 is provided at the lower end of the power switch body 1. The terminal post 8 is used to connect an external power supply device. Specifically, the power switch body further includes a contact assembly connected to the control handle. When the control handle is rotated so that the electrode plates in the contact assembly are in contact, the terminal post is electrically connected to the external power supply device. Otherwise, there is no current passing through the terminal post, and the external power supply device is in a power-off state.

[0045] When the self-locking power switch of the present utility model is in use, the power switch body can be first connected to the power supply end of the engineering vehicle through the terminal post, and then the driver rotates the control handle so that the lower end of the limiting rod extends into the limiting groove. At this time, the power switch body is in the on state. When it is necessary to turn off the power switch body, the lower end of the limiting rod can be lifted upward, and then the limiting rod is pushed or the control handle is rotated in the reverse direction to switch the state of the power switch body.

[0046] The self-locking power switch proposed by the present utility model is provided with a locking assembly and a control handle on the connection cover. The locking assembly includes an arc-shaped limiting tube with an upper chute, a limiting rod, and a limiting groove. The limiting rod is configured to be able to slide along the chute, and the limiting groove is set to penetrate and extend beyond the lower wall of the arc-shaped limiting tube for limiting the limiting rod. The control handle is provided with a connecting rod, and one end of the connecting rod passes through the arc-shaped limiting tube through the limiting rod, so that when the power switch body is in the on state, the limiting rod can lock the control handle through the connecting rod.

[0047] Therefore, compared with the existing power switch, the self-locking power switch of the present utility model can be locked by using the limiting rod and the limiting groove when the power switch body is in the on state to prevent accidental touch by the driver during operation, and the connecting rod can slide along the arc-shaped limiting tube driven by the limiting rod to adjust the rotation angle of the control handle, so as to be able to switch the state of the power switch in time, improving the use safety of the power switch and being beneficial to construction use.

[0048] Although one or more embodiments of the present utility model have been described above, 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.
