Description

Technical Field

[0001] This utility model belongs to the field of disconnecting switch technology, and in particular relates to a disconnecting switch that is easy to install. Background Technology

[0002] In the process of power system installation and power distribution equipment layout, disconnect switches are key electrical components, and their ease of installation and adaptability directly affect construction efficiency and subsequent operation and maintenance results.

[0003] Traditional disconnect switches are mostly fixed directly to the mounting surface. During installation, the switch body and the holes of the pre-embedded structure in the wall must be precisely aligned. If there is any deviation in the hole position, it must be disassembled and reinstalled, resulting in a high rework rate and long installation time. Therefore, a disconnect switch that is easy to install is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide an easy-to-install disconnect switch. By setting a fixing component, specifically, the limiting hole of the side lug is aligned with the knob and inserted, then the knob is rotated to drive the rotating rod to rotate. After the back of the side lug is in contact with the front of the mounting bracket, the knob is released, and the spiral spring returns to its original position, driving the rotating rod and the pressure plate to rotate and return to their original positions. The pressure plate limits the side lug, and at the same time, the spring plate group pushes the pressure plate to hold the side lug, realizing the rapid fixing of the switch housing. This solves the problem that traditional disconnect switches mostly use the method of directly fixing the switch body to the mounting surface. During installation, the holes of the switch body and the pre-embedded structure in the wall need to be accurately aligned. If there is a deviation in the hole position, it is necessary to disassemble and reinstall, resulting in a high rework rate and long installation time.

After the back of the side ear 212 is in contact with the front of the mounting bracket 211, release the knob 215. The spiral spring 2112 resets and drives the rotating rod 214 and the pressure plate 219 to rotate and reset. The pressure plate 219 limits the side ear 212. At the same time, the spring piece group 210 pushes the pressure plate 219 to hold the side ear 212, realizing the quick fixation of the switch housing 113 without the need for cumbersome bolt tightening, greatly shortening the installation time and improving construction efficiency.

[0027] Two rotating rods 214 pass through the cavity 2111 and extend to the front of the mounting bracket 211. The outer surfaces of the two rotating rods 214 are rotatably connected to the front of the inside of the mounting bracket 211.

A limiting piece 226 is provided on the back of the lug 224. The center of the limiting piece 226 is fixedly connected to the outer surface of the pin 225. A spring 227 is sleeved on the outer surface of the limiting piece 226. The back of the spring 227 is connected to... The limiting piece 226 is fixedly connected to the side away from the support rod 221. The spring 227 is fixedly connected to the back of the lug 224 on the side away from the limiting piece 226. The back of the limiting piece 226 is in contact with the front of the support rod 221. Several balls 228 are rotatably connected to the top and bottom of the inner side of the mounting bracket 211. The balls 228 are arranged in two sets, and the outer surfaces of the two sets of balls 228 are slidably connected to the inside of the slide rail 223. Pulling the pin 225 can release the fixing of the mounting bracket 211 and the support rod 221. The mounting bracket 211 moves laterally along the slide rail 223 through the balls 228. The installation position of the switch housing 113 can be flexibly adjusted according to the wiring position and terminal connection requirements on site, reducing the bending caused by wiring pulling, reducing safety hazards such as poor contact and insulation damage, and adapting to the layout requirements of different installation spaces, thus enhancing the product's versatility.

[0029] The limiting component includes two sector-shaped limiting grooves 217 formed on the front of the mounting bracket 211. Each sector-shaped limiting groove 217 has a limiting pin 218 inside. The two limiting pins 218 are fixedly connected to the outer surface of the rotating rod 214. The included angle between the inside of the sector-shaped limiting grooves 217 is set at 94 degrees, and the maximum rotation angle of the limiting pins 218 is set at 90 degrees.

[0030] One specific application of this embodiment is as follows: In use, the mounting plate 111 is first fixed to the preset mounting surface of the wall with bolts to complete the basic installation positioning; then the switch housing 113 is fixed. The operator first holds the knob 215 and rotates the rotating rod 214. The rotating rod 214 drives the limiting frame 216 and the pressure plate 219 to rotate synchronously. At this time, the spiral spring 2112 in the cavity 2111 is twisted and stores force, and the limiting pin 218 on the rotating rod 214 rotates along the fan-shaped limiting groove 217 to the limit. Position; Align the limiting holes 213 on the side ears 212 on both sides of the switch housing 113 with the knob 215 and insert it. Push the switch housing 113 so that the back of the side ears 212 is in close contact with the front of the mounting bracket 211. At this time, release the knob 215. The spiral spring 2112 resets and drives the rotating rod 214 to rotate in the opposite direction. The pressure plate 219 rotates with the rotating rod 214 to the front of the limiting hole 213. The spring piece group 210 pushes the pressure plate 219 to press and hold the side ears 212 on the front, thereby achieving the limiting and fixing of the switch housing 113.

[0031] If the lateral position of the switch housing 113 needs to be adjusted, pull the pull ring of the pin 225. The pin 225 drives the limit plate 226 to compress the spring 227, and the pin 225 disengages from the pin hole 222 of the support rod 221. At this time, the mounting bracket 211 can slide laterally along the slide rail 223 of the support rod 221 through the ball bearing 228. After adjusting to the appropriate position according to the wiring requirements, release the pull ring. The spring 227 returns to its original position and pushes the pin 225 into the corresponding pin hole 222, thus completing the position fixation. The wire clamp 112 on the mounting plate 111 can organize and fix the wires connected to the switch housing 113 to avoid messy and tangled wires.

[0032] When performing maintenance or replacing the switch housing 113, simply hold the knob 215 and rotate the lever 214 to make the pressure plate 219 rotate out of the limiting range of the limiting hole 213. Then, you can directly pull the switch housing 113 outward to remove it without disassembling the mounting plate 111. This operation is convenient and will not damage the wall.
