[0002] Load switches generally refer to switches used to control electrical equipment or circuit loads. These include high-voltage load switches used in high-voltage circuits. Some high-voltage load switches are usually installed in power equipment cabinets and are bolted to brackets in the cabinet. When installing a high-voltage load switch on a bracket, it is necessary to align the bolt holes on the high-voltage load switch frame with the bolt holes on the bracket in the cabinet. However, due to the small space in the cabinet and limited vision, the position of the load switch needs to be repeatedly adjusted slightly until the holes are accurately aligned, making the operation very complicated and difficult. Utility Model Content

[0003] The utility model aims to propose a load switch for the problem that when a high-voltage load switch is installed on a bracket in an electric power equipment cabinet, the bolt holes on the high-voltage load switch frame need to be aligned with the bolt holes of the bracket in the cabinet. However, due to the narrow space in the cabinet and the limited field of vision, the position of the load switch needs to be repeatedly and slightly adjusted until the holes are accurately aligned, which makes the operation very complicated and difficult.

[0005] Optionally, the abutting mechanism includes a plurality of protrusions arranged on the outer wall of the turntable and distributed in a circular array, the arc-shaped ends of the protrusions away from the turntable are each provided with a slot, and the end of the telescopic slide rod close to the turntable is fixedly connected with a top block that abuts against the turntable.

[0006] Optionally, a movable sleeve on the outer wall of the telescopic slide rod is provided with a return spring, one end of the return spring is fixedly connected to the support block, and the other end of the return spring is fixedly connected to the top block.

[0007] Optionally, a hexagonal groove for inserting a hexagonal screwdriver is provided in the middle of the turntable.

[0008] Optionally, the rotating mechanism comprises a rotating block and a rotating sleeve that are movably connected, one end of the rotating block inserted into the rotating sleeve is fixedly connected to a chuck, and an end of the rotating sleeve close to the turntable is fixedly connected to a clamping ring for clamping the chuck.

[0009] Optionally, slots for the top block to be inserted into are provided between the protrusions on the outside of the turntable.

[0010] Optionally, the angles between the multiple telescopic sliding rods are 90° with the hexagonal groove as the center.

[0011] Compared with the prior art, the utility model has the following beneficial technical effects:

[0012] The utility model utilizes the coordination of the switch body, the turntable, the abutment mechanism and the rotation mechanism, so that when the load switch is installed in the power equipment cabinet, it can not only avoid the challenge of bolt hole alignment. At the same time, compared with the installation of bolts one by one, only the turntable can be rotated with a hexagonal screwdriver to complete the installation of the load switch on the bracket in the cabinet, which not only reduces the difficulty of installation, but also shortens the installation time and improves work efficiency.
