Description

Technical Field

[0001] This utility model relates to the field of grounding device technology, and in particular to a retractable grounding device. Background Technology

[0002] A grounding device is used to prevent electric shock to people, damage to equipment and lines, fire, lightning strikes, static electricity damage, and to ensure the normal operation of the power system. When using a grounding device, one end of the connecting plate is inserted into the ground, and the connecting plate on the top of the grounding device is connected to the grounding wire. In this way, grounding can be performed through the grounding wire and the grounding device.

[0003] In their daily work, the inventors discovered that grounding devices still have at least the following problems: When using a grounding device, one end of the connecting plate is inserted into the ground, and the connecting plate on the top of the grounding device body is connected to a grounding wire. This allows for grounding operations through the grounding wire and the grounding device. However, in actual use, the length of the grounding device is consistent, and different models of grounding devices need to be replaced if different lengths are required, which is quite troublesome. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a retractable grounding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a retractable grounding device, comprising a grounding device body, connecting plates installed at both ends of the grounding device body, a connecting device provided on one side of the grounding device body, the connecting device comprising a connecting cylinder, a connecting rod slidably connected to the inner wall of the connecting cylinder, the top of the connecting cylinder and the connecting plate being disposed together, the bottom of the connecting rod being disposed together with another connecting plate, a sliding cylinder being fixedly connected to the bottom of the connecting cylinder, and a bolt threaded through and inserted on one side of the sliding cylinder.

[0006] The effect achieved by the above components is as follows: when using the connecting device, the connecting rod is controlled to slide on the inner wall of the connecting cylinder. When the connecting rod slides to the appropriate position, the bolt is manually controlled to rotate, thereby pressing the bolt against one side of the connecting rod, which can change the length of the grounding device.

[0007] Preferably, a rubber cylinder is fixedly connected to the bottom of the sliding cylinder, and the rubber cylinder is sleeved on the surface of the connecting rod.

[0008] The effect achieved by the above components is that when the rubber sleeve is fitted onto the surface of the connecting rod, the inner wall of the rubber sleeve is pressed against the surface of the connecting rod, thus confining the connecting rod to the inner wall of the connecting sleeve.

[0009] Preferably, a rectangular rod is fixedly connected to the top of the inner wall of the connecting cylinder, and the rectangular rod is slidably inserted into the top of the connecting rod.

[0010] The effect achieved by the above components is that by inserting the rectangular rod at the top of the connecting rod, the connecting rod can be prevented from rotating on the inner wall of the connecting cylinder.

[0011] Preferably, a support plate is fixedly connected to the bottom of the rectangular rod, and support blocks are uniformly fixedly connected to the bottom of the rectangular rod. A rotating rod is fixedly connected between two support blocks. A rotating plate is rotatably sleeved on the surface of the rotating rod. A cylinder is rotatably inserted into the inner wall of the bottom of the rotating plate. A first spring is fixedly connected to both sides of the support plate. The end of the first spring away from the support plate is fixedly connected to one side of the rotating plate. A baffle is uniformly fixedly connected to the bottom of the rectangular rod. The baffle is located on the side of the rotating plate close to the support plate.

[0012] The effect achieved by the above components is as follows: the first spring presses the rotating plate away from the support plate, thereby pressing the bottom of the rotating plate against the inner wall of the connecting rod. When the rectangular rod moves, the cylinder is driven to rotate, thereby allowing the rectangular rod to slide well in the inner wall of the connecting rod. The baffle can prevent the rotating plate from rotating towards the support plate.

[0013] Preferably, a support device is provided on the bottom surface of the connecting rod. The support device includes a sliding ring, which is slidably sleeved on the surface of the connecting rod. Fixing nails are uniformly fixedly connected to the bottom of the sliding ring, and a fixing plate is fixedly connected to the bottom surface of the connecting rod. The fixing plate is located at the bottom of the sliding ring.

[0014] The effect achieved by the above components is as follows: when using the support device, the connecting plate fixed at the bottom of the connecting rod is inserted into the ground, then the sliding ring is placed on the surface of the bottom of the connecting rod, and then the fixing nail is inserted into the ground. In this way, the grounding device can be supported by the sliding ring.

[0015] Preferably, a support ring is fixedly connected to the surface of the connecting rod, and a damping rod is uniformly fixedly connected to the bottom of the support ring. The bottom of the damping rod is fixedly connected to the top of the sliding ring, and a second spring is sleeved on the surface of the damping rod. One end of the second spring is fixedly connected to the top of the sliding ring, and the end of the second spring away from the sliding ring is fixedly connected to the bottom of the support ring.

[0016] The effect achieved by the above components is that the sliding ring is pressed away from the support ring by the second spring, so that the sliding ring can be set on the top of the fixed plate.

[0017] Preferably, the top of the sliding ring is provided with a connecting groove, and a support bar is slidably connected to the inner wall of the connecting groove. The support bar is disposed at the bottom of the support ring.

[0018] The effect achieved by the above components is: to manually control the support bar to slide on the inner wall of the connecting groove, thereby setting the top of the support bar at the bottom of the support ring, which makes it easier to set the sliding ring at the top of the fixed plate.

[0019] Preferably, the bottom of the support ring is uniformly fixedly connected with rubber rings, and the top of the support strip is positioned between the two rubber rings.

[0020] The effect achieved by the above components is to press the top of the support bar into the middle of the two rubber rings, which makes it easier to restrict the support bar to the bottom of the support ring.

[0021] In this invention, by setting a connecting device, when using the connecting device, the connecting rod is controlled to slide on the inner wall of the connecting cylinder. When the connecting rod slides to the appropriate position, the bolt is manually controlled to rotate, thereby pressing the bolt against one side of the connecting rod, which can change the length of the grounding device.

[0027] Example 1, as Figure 1-4As shown, a retractable grounding device is provided. Both ends of the grounding device body 1 are equipped with connecting plates 2, and a connecting device 3 is provided on one side of the grounding device body 1. When using the grounding device, one end of the connecting plate 2 is inserted into the ground. The connecting plate 2 provided on the top of the grounding device body 1 is connected to a grounding wire. In this way, grounding operation can be performed through the grounding wire and the grounding device.

[0028] Reference Figure 2 and Figure 3 The connecting device 3 includes a connecting cylinder 301, with a connecting rod 302 slidably connected to the inner wall of the connecting cylinder 301. The top of the connecting cylinder 301 is set together with a connecting plate 2, and the bottom of the connecting rod 302 is set together with another connecting plate 2. A sliding cylinder 304 is fixedly connected to the bottom of the connecting cylinder 301, and a bolt 305 is threaded through one side of the sliding cylinder 304. When using the connecting device 3, the connecting rod 302 is controlled to slide on the inner wall of the connecting cylinder 301. When the connecting rod 302 slides to a suitable position, the bolt 305 is manually controlled to rotate, thereby causing the bolt 305 to squeeze out. A rubber cylinder 306 is fixedly connected to the bottom of the sliding cylinder 304. The rubber cylinder 306 is sleeved on the surface of the connecting rod 302. When the rubber cylinder 306 is sleeved on the surface of the connecting rod 302, the inner wall of the rubber cylinder 306 is pressed against the surface of the connecting rod 302, thus restricting the connecting rod 302 to the inner wall of the connecting cylinder 301. A rectangular rod 303 is fixedly connected to the top of the inner wall of the connecting cylinder 301. The rectangular rod 303 is slidably inserted into the top of the connecting rod 302. The top of the rectangular rod 303 is fixed to prevent the connecting rod 302 from rotating on the inner wall of the connecting cylinder 301. A support plate 312 is fixedly connected to the bottom of the rectangular rod 303. Support blocks 307 are evenly fixedly connected to the bottom of the rectangular rod 303. A rotating rod 308 is fixedly connected between the two support blocks 307. A rotating plate 309 is rotatably fitted on the surface of the rotating rod 308. A cylinder 310 is rotatably inserted into the inner wall of the bottom of the rotating plate 309. First springs 311 are fixedly connected to both sides of the support plate 312. The end of the first spring 311 away from the support plate 312 is fixed to one side of the rotating plate 309. The rectangular rod 303 is uniformly fixedly connected to the bottom of a baffle 313. The baffle 313 is located on the side of the rotating plate 309 near the support plate 312. The first spring 311 presses the rotating plate 309 away from the support plate 312, so that the bottom of the rotating plate 309 is pressed into the inner wall of the connecting rod 302. When the rectangular rod 303 moves, the cylinder 310 is driven to rotate, so that the rectangular rod 303 can slide well in the inner wall of the connecting rod 302. The baffle 313 can prevent the rotating plate 309 from rotating towards the support plate 312.

[0029] Reference Figure 4A support device 4 is provided on the bottom surface of the connecting rod 302. The support device 4 includes a sliding ring 401, which is slidably sleeved on the surface of the connecting rod 302. Fixing pins 403 are evenly fixedly connected to the bottom of the sliding ring 401. A fixing plate 402 is fixedly connected to the bottom surface of the connecting rod 302, and the fixing plate 402 is located at the bottom of the sliding ring 401. When using the support device 4, the connecting plate 2 fixed to the bottom of the connecting rod 302 is inserted into the ground, then the sliding ring 401 is sleeved on the bottom surface of the connecting rod 302, and then the fixing pins 403 are inserted into the ground. This allows the grounding device to be supported by the sliding ring 401. A support ring 404 is fixedly connected to the surface of the connecting rod 302. A damping rod 405 is evenly fixedly connected to the bottom of the support ring 404. The bottom of the damping rod 405 is fixedly connected to the top of the sliding ring 401. A second spring 406 is sleeved on the surface of the damping rod 405, and one end of the second spring 406 is connected to the sliding ring 401. The top is fixedly connected, and the end of the second spring 406 away from the sliding ring 401 is fixedly connected to the bottom of the support ring 404. The second spring 406 presses the sliding ring 401 away from the support ring 404, so that the sliding ring 401 can be set on the top of the fixed plate 402. The top of the sliding ring 401 is evenly provided with connecting grooves 407. The inner wall of the connecting groove 407 is slidably connected with a support bar 408. The support bar 408 is set at the bottom of the support ring 404. The support bar 408 is manually controlled to slide on the inner wall of the connecting groove 407, so that the top of the support bar 408 is set at the bottom of the support ring 404. This makes it easy to set the sliding ring 401 on the top of the fixed plate 402. The bottom of the support ring 404 is evenly fixedly connected with rubber rings 409. The top of the support bar 408 is set in the middle of the two rubber rings 409. The top of the support bar 408 is pressed into the middle of the two rubber rings 409, so that the support bar 408 is restricted to the bottom of the support ring 404.

[0030] Working principle: When using the grounding device, one end of the connecting plate 2 is inserted into the ground. The connecting plate 2, located on the top of the grounding device body 1, is connected to a grounding wire. Grounding can be performed through the grounding wire and the grounding device. When using the connecting device 3, the connecting rod 302 is controlled to slide on the inner wall of the connecting cylinder 301. The rectangular rod 303 is inserted on the top of the connecting rod 302 to prevent the connecting rod 302 from rotating on the inner wall of the connecting cylinder 301. When the connecting rod 302 slides to the appropriate position, the rubber cylinder 306 is fitted onto the surface of the connecting rod 302. The inner wall of the rubber cylinder 306 presses against the surface of the connecting rod 302, thus restricting the connecting rod 302 to the inner wall of the connecting cylinder 301. Then, the bolt 305 is manually rotated, causing the bolt 305 to press against one side of the connecting rod 302. This changes the length of the grounding device. The first spring 311 presses the rotating plate 309 away from the support plate 312, thereby causing the rotating plate 309 to rotate. The bottom of 09 is pressed into the inner wall of the connecting rod 302. When the rectangular rod 303 moves, the cylinder 310 is driven to rotate, which allows the rectangular rod 303 to slide well in the inner wall of the connecting rod 302. The baffle 313 can prevent the rotating plate 309 from rotating towards the support plate 312. When using the support device 4, the connecting plate 2 fixed at the bottom of the connecting rod 302 is inserted into the ground. The sliding ring 401 is pressed away from the support ring 404 by the second spring 406. This allows the sliding ring 401 to be set at the top of the fixed plate 402. Then, the support bar 408 is manually controlled to slide in the inner wall of the connecting groove 407, pressing the top of the support bar 408 into the middle of the two rubber rings 409. This makes it easy to restrict the support bar 408 to the bottom of the support ring 404, which makes it easy to set the sliding ring 401 at the top of the fixed plate 402. Then, the fixing nail 403 is inserted into the ground. The grounding device can be supported by the sliding ring 401.

[0031] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
