[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0022] Example 1

[0023] This embodiment provides a 10kV handcart switch operating handle, such as... Figures 1-2 ,

[0024] It includes a main body assembly 100, which includes a crank handle 101 and a fixing plate 102. The crank handle 101 is provided with a first connecting member 101d, and the fixing plate 102 is provided with a second connecting member 102a; and a stabilizing assembly 200, which includes a housing 201, a support foot 202, a tensioning mechanism 203, and a clamping mechanism 204. The housing 201 is rotatably connected to the crank handle 101, and the housing 201 has a cavity inside. The tensioning mechanism 203 is located in the cavity. One end of the support foot 202 is fixedly connected to the outer wall of the housing 201, and the clamping mechanism 204 is located at the end of the support foot 202 away from the housing 201.

[0025] The fixing plate 102 is fixedly installed on one side of the 10kV handcart switch operating vehicle. When the first connecting member 101d and the second connecting member 102a are engaged, the crank handle 101 is connected to the fixing plate 102. At this time, turning the crank handle 101 can move the 10kV handcart switch operating vehicle. The stabilizing component 200, using the support foot 202, can make the crank handle 101 reach a relatively stable state during the cranking process, and the crank handle 101 is not easy to fall off the fixing plate 102.

[0026] During the cranking of the handle 101, the tensioning mechanism 203 is tightened, causing the clamping mechanism 204 to clamp. The clamping mechanism 204 firmly fixes the handle 101 to the fixed plate 102, and the handle 101 is firmly connected to the fixed plate 102. When the operation of the handle 101 is finished, the tensioning mechanism 203 is released. At this time, the clamping effect of the clamping mechanism 204 disappears, and the handle 101 can be smoothly separated from the fixed plate 102.

[0027] The crank handle 101 includes a first rod 101a, a second rod 101b, and a third rod 101c. One end of the first rod 101a is fixedly connected to the second rod 101b, and the first rod 101a and the second rod 101b are perpendicular. The end of the second rod 101b away from the first rod 101a is fixedly connected to the third rod 101c, and the second rod 101b and the third rod 101c are perpendicular. The first rod 101a and the third rod 101c are parallel. The axes of the first rod 101a, the second rod 101b, and the third rod 101c are located in the same plane. The first connecting member 101d is disposed at the end of the third rod 101c away from the second rod 101b.

[0028] The first connector 101d is an internal hexagonal groove.

[0029] The second connector 102a is a hexagonal protrusion, which is fixed at the middle position of the fixing plate 102.

[0030] The first connector 101d and the second connector 102a are plug-in mating.

[0031] Example 2

[0032] This embodiment provides a 10kV handcart switch operating handle 101, such as... Figures 3-5 This embodiment is based on Embodiment 1, but differs from Embodiment 1 in that:

[0033] The tensioning mechanism 203 includes a centrifugal component 203a and a rotating component 203b. The centrifugal component 203a is sleeved on the crank handle 101, and the rotating component 203b is disposed outside the centrifugal component 203a.

[0034] The centrifugal component 203a includes an inner ring 203a-1, a plurality of first throwing blocks 203a-2, and a plurality of second throwing blocks 203a-3. The inner ring 203a-1 is fixedly sleeved on the third rod 101c. The inner ring 203a-1 is provided with an annular groove. The plurality of first throwing blocks 203a-2 are evenly distributed in the annular groove. One end of the plurality of first throwing blocks 203a-2 is movably connected in the annular groove. One side of the first throwing block 203a-2 is connected to the bottom surface of the annular groove by a first spring 203a-4. The plurality of second throwing blocks 203a-3 are evenly distributed in the annular groove. One end of the plurality of second throwing blocks 203a-3 is movably connected in the annular groove. One side of the second throwing block 203a-3 is connected to the bottom surface of the annular groove by a first spring 203a-4. The first throwing blocks 203a-2 and the second throwing blocks 203a-3 are distributed in opposite directions in the annular groove.

[0035] The rotating component 203b includes an outer ring 203b-1, a fixing block 203b-2, a second spring 203b-3, and a pull rope 203b-4. The inner ring of the outer ring 203b-1 has a groove. The ends of the first swing block 203a-2 and the second swing block 203a-3 away from the annular groove are directly opposite the groove. The outer ring 203b-1 is sleeved on the outside of the inner ring 203a-1. Two fixing blocks 203b-2 are symmetrically arranged on the outside of the outer ring 203b-1. One end of the pull rope 203b-4 is fixedly connected to each of the two fixing blocks 203b-2. The other end of the pull rope 203b-4 passes through the outer shell 201 and is fixedly connected to the clamping mechanism 204. One end of the second spring 203b-3 is fixedly connected to the fixing block 203b-2, and the other end of the second spring 203b-3 is fixedly connected to the inner wall of the outer shell 201.

[0036] Both the first throwing block 203a-2 and the second throwing block 203a-3 are rotatably connected at one end to an annular groove, which contains a pin. The bottoms of both the first throwing block 203a-2 and the second throwing block 203a-3 have circular holes. The first throwing block 203a-2 and the second throwing block 203a-3 are fitted onto the pin, and rotate about the pin in a circular motion. When the inner ring 203a-1 rotates, the first throwing block 203a-2 and the second throwing block 203a-3... Under the action of centrifugal force, the end of the first throwing block 203a-1 away from the inner ring 203a-1 tends to move away from the inner ring 203a-1. That is, under the action of centrifugal force, the ends of the first throwing block 203a-2 and the second throwing block 203a-3 away from the inner ring 203a-1 move towards the groove of the outer ring 203b-1 until the first throwing block 203a-2 and the second throwing block 203a-3 contact the groove of the outer ring 203b-1. During this process, the first spring 203a-4 is stretched.

[0037] Since the first throwing block 203a-2 and the second throwing block 203a-3 are distributed in opposite directions within the annular groove, when the inner ring 203a-1 rotates clockwise (when the 10kV handcart switch operating trolley is moved out), the end of the first throwing block 203a-2 away from the inner ring 203a-1 contacts the groove of the outer ring 203b-1, and then the outer ring 203b-1 begins to rotate clockwise under the action of friction. At this time, the second throwing block 203a-3 is tightly attached to the annular groove. When the inner ring 203a-1 rotates counterclockwise (when the 10kV handcart switch operating trolley is moved in), the end of the second throwing block 203a-3 away from the inner ring 203a-1 contacts the groove of the outer ring 203b-1, and then the outer ring 203b-1 begins to rotate counterclockwise under the action of friction. At this time, the first throwing block 203a-2 is tightly attached to the annular groove.

[0038] When the outer ring 203b-1 rotates, the fixed block 203b-2 rotates under the action of the outer ring 203b-1. The pull rope 203b-4 is then pulled by the fixed block 203b-2. The pull rope 203b-4 is a rigid rope, which in turn pulls the clamping mechanism 204 at the other end of the pull rope 203b-4, clamping the fixed plate 102. There are two fixed blocks 203b-2, symmetrically distributed on the outer ring 203b-1. Each fixed block 203b-2 is equipped with a second spring 203b-3. The pull rope 203b-4 passes through the inside of the second spring 203b-3. Therefore, when the outer ring 203b-1 rotates, both second springs 203b-3 are stretched.

[0039] The clamping mechanism 204 includes a first clamping plate 204a, a second clamping plate 204b, and a third spring 204c. The first clamping plate 204a is fixedly connected to the end of the support foot 202 away from the outer shell 201. The second clamping plate 204b is sleeved on the support foot 202 and is slidably connected to the support foot 202. The third spring 204c is provided between the second clamping plate 204b and the first clamping plate 204a. The pull rope 203b-4 passes through the first clamping plate 204a and the third spring 204c and is fixedly connected to the second clamping plate 204b. The first clamping plate 204a and the second clamping plate 204b are located on both sides of the fixing plate 102.

[0040] Rubber pads are provided at the adjacent ends of the first clamping plate 204a and the second clamping plate 204b.

[0041] The second clamping plate 204b is slidably connected to the support foot 202, meaning that the second clamping plate 204b can slide along the support foot 202. Since the end of the pull rope 203b-4 away from the outer ring 203b-1 is fixedly connected to the second clamping plate 204b, when the pull rope 203b-4 is stretched, the second clamping plate 204b moves towards the first clamping plate 204a under the action of the pull rope 203b-4. That is, the first clamping plate 204a and the second clamping plate 204b clamp the fixing plate 102, so the crank handle 101 is stably connected to the fixing plate 102 during operation.

[0042] A rubber pad is provided on the side of the first clamping plate 204a and the second clamping plate 204b that is close to each other. When the first clamping plate 204a and the second clamping plate 204b clamp the fixing plate 102, the rubber pad can fit better with the fixing plate 102, and the rubber pad has a large friction force, which can make the first clamping plate 204a and the second clamping plate 204b clamp the fixing plate 102 more stably.
