Each support frame is connected to a height adjustment rod for adjusting its height. However, the installation of the above-mentioned grounding resistance meter is rather cumbersome. Therefore, this solution provides a grounding resistance mechanism that is easy to install to solve the above-mentioned problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, a grounding resistor mechanism that is easy to install is provided. This technical solution solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An easy-to-install grounding resistor mechanism includes a mounting platform. Two sets of positioning blocks are fixedly connected to the upper end of the mounting platform. A vibration damping pad is provided between the two sets of positioning blocks. A grounding resistor body is placed on the vibration damping pad. The front and rear sides of the grounding resistor body are provided with slots opened on the mounting platform. A first fixing mechanism and a second fixing mechanism are respectively provided inside the slots on the front and rear sides. The front and rear ends of the grounding resistor body are provided with snap-fit ​​seats for cooperating with the first fixing mechanism and the second fixing mechanism to fix the grounding resistor body.

[0007] Preferably, the first fixing mechanism and the second fixing mechanism have the same overall structure, and the first fixing mechanism as a whole includes a base, a clamping component, a locking component and a buffer component.

[0008] Preferably, the base includes an L-shaped substrate placed in an empty slot. The left and right sides of the middle of the L-shaped substrate are provided with a connected sliding groove and a guide groove, and an installation groove is provided between the two sliding grooves at the top of the L-shaped substrate.

[0009] Preferably, the clamping assembly includes a center block fixedly mounted on an L-shaped substrate. The center block is located in the middle of the guide groove, and a hinge block is fixedly connected to the front end of the center block. A knob is fixedly connected to the middle of the front end of the hinge block, and hinge holes are opened through both ends of the hinge block. A first drive plate and a second drive plate are slidably mounted inside the hinge holes on both sides, and a fixing part is fixedly connected to the other end of the first drive plate and the second drive plate.

[0010] Preferably, the fixing part includes two sets of sliding blocks that are slidably installed inside the sliding grooves on both sides, and connecting plates that are fixedly installed on the two sets of sliding blocks. A clamping plate is fixedly connected to the far end of each set of sliding blocks, and a clamping block that is adapted to the clamping seat is fixedly connected to each clamping plate. Several springs are fixedly connected between the other end of each set of sliding blocks and the sliding groove. Both sets of connecting plates extend out through guide grooves and are fixedly connected to drive plate one and drive plate two, respectively.

[0011] Preferably, the locking assembly includes a limiting plate that is slidably installed in the mounting groove, and a plug rod that is fixedly connected to the limiting plate. A spring 2 sleeved on the plug rod is fixedly connected between the limiting plate and the mounting groove. A pull ring is fixedly connected to the upper end of the plug rod, and the lower end of the plug rod passes through the L-shaped base plate and engages with the center block. A matching slot is provided on the center block.

[0012] Preferably, the buffer assembly includes a top plate fixedly mounted on the mounting platform, and a damper and a buffer spring are fixedly mounted between the lower end of the top plate and the bottom plate of the L-shaped base plate, with the buffer spring sleeved on the outside of the damper.

[0013] Compared with the prior art, this utility model proposes a grounding resistor mechanism that is easy to install and has the following beneficial effects:

[0014] 1. This utility model includes a clamping assembly. By rotating the knob in the clamping part, the hinge block rotates, pushing the drive plate one and drive plate two outward through the two hinge holes. Simultaneously, drive plate one and drive plate two, through the connecting plates on both sides, drive the sliding blocks on both sides to slide outward in the slide groove, thereby moving the clamping plate and the locking block on it outward. Then, by placing the grounding resistor through the positioning block, the locking seat is positioned between the locking blocks on both sides. Then, by releasing the knob, under the action of spring one, the locking block on the clamping plate engages with the locking seat of the grounding resistor body, completing the fixation. By adopting a central hinge bidirectional synchronous drive mechanical motion structure, it is ensured that the locking blocks on both sides clamp the locking seat with the same force, avoiding the problem of unilateral force or tilted fixation, making the installation more secure and reliable. At the same time, by simply rotating a single knob, the clamping mechanisms on both sides can be driven synchronously to complete the fixing or release of the resistor, saving time and effort, eliminating the need for additional tools, effectively improving maintenance efficiency and reducing maintenance time.

[0015] 2. This utility model is equipped with a locking component. When the latching block in the clamping component enters the latching seat under the action of spring one, the slot on the center block is aligned with the insert rod in the locking component. Under the action of spring two, the lower end of the insert rod is inserted into the slot, thereby fixing the center block and locking the knob to prevent the knob from rotating due to vibration or accidental contact. To unlock, simply pull the pull ring upwards.

[0016] 3. This utility model is equipped with a buffer component. The buffer spring provides elastic support, and the damper consumes vibration energy. When there is a strong external impact or vibration, the entire fixing mechanism can float slightly in the slot, thereby further protecting the grounding resistor body and preventing the fixing point from being damaged due to rigid connection. In conjunction with the vibration damping pad, the overall buffering effect is further improved. Attached Figure Description

[0030] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0031] Reference Figure 1-2 As shown, a grounding resistor mechanism that is easy to install includes a mounting platform 1. Two sets of positioning blocks 101 are fixedly connected to the upper end of the mounting platform 1. A vibration damping pad 102 is provided between the two sets of positioning blocks 101. A grounding resistor body 2 is placed on the vibration damping pad 102. The front and rear sides of the grounding resistor body 2 are provided with slots 103 opened on the mounting platform 1. The front and rear slots 103 are respectively provided with a first fixing mechanism 3 and a second fixing mechanism 4. The front and rear ends of the grounding resistor body 2 are provided with locking seats 5 for cooperating with the first fixing mechanism 3 and the second fixing mechanism 4 to fix the grounding resistor body 2.

[0032] Furthermore: the positioning block 101 is used to initially position the grounding resistor, facilitating quick positioning and flipping, and is quickly fixed by engaging with the snap-fit ​​seat 5 on the resistor body 2 through the first fixing mechanism 3 and the second fixing mechanism 4. This simplifies the fixing operation process, improves the installation and disassembly efficiency of the grounding resistor body 2, and ensures the reliability of the connection after fixing.

[0033] Reference Figure 3 As shown, specifically, in this embodiment, the first fixing mechanism 3 and the second fixing mechanism 4 have the same overall structure, and the first fixing mechanism 3 as a whole includes a base 31, a clamping component 32, a locking component 33 and a buffer component 34.

[0034] Furthermore: the first fixing mechanism 3 and the second fixing mechanism 4 adopt the same structural design, which can realize symmetrical fixing of the front and rear ends of the grounding resistor body 2, ensuring that the clamping force on the grounding resistor body 2 is balanced, and avoiding the problem of displacement or loosening due to uneven force; the base 31 serves as a carrier, providing installation positions for each component and ensuring the coordinated work between the components; the clamping component 32 completes the clamping and releasing operation of the snap-fit ​​seat 5 through a mechanical transmission structure; the locking component 33 is used to lock the working state of the clamping component 32, preventing it from being accidentally loosened due to vibration, external force contact, etc., and improving the reliability of fixing; the buffer component 34 is connected between the mounting platform 1 and the base 31, and works with the vibration damping pad 102 to form a double vibration damping effect, improving the overall vibration resistance of the mechanism.

[0035] Reference Figure 4-5 As shown, specifically, in this embodiment, the base 31 includes an L-shaped substrate 311 placed in the empty slot 103. The left and right sides of the middle of the L-shaped substrate 311 are provided with a connected sliding groove 312 and a guide groove 313. A mounting groove 314 is provided between the two sliding grooves 312 on the top of the L-shaped substrate 311.

[0036] Reference Figure 4-5 As shown, specifically in this embodiment, the clamping assembly 32 includes a central block 321 fixedly mounted on an L-shaped substrate 311. The central block 321 is located in the middle of the guide groove 313, and a hinge block 323 is fixedly connected to the front end of the central block 321. A knob 322 is fixedly connected to the middle of the front end of the hinge block 323, and hinge holes 324 are opened through both ends of the hinge block 323. A first drive plate 325 and a second drive plate 326 are slidably mounted inside the hinge holes 324 on both sides, and a fixing part is fixedly connected to the other end of the first drive plate 325 and the second drive plate 326.

[0037] Reference Figure 4-5As shown, specifically in this embodiment, the fixing part includes two sets of sliding blocks 328 that are slidably installed inside the sliding grooves 312 on both sides, and connecting plates 327 that are fixedly installed on the two sets of sliding blocks 328. A clamping plate 329 is fixedly connected to the far end of each set of sliding blocks 328. A locking block 3210 that is adapted to the locking seat 5 is fixedly connected to each clamping plate 329. A plurality of springs 3211 are fixedly connected between the other end of each set of sliding blocks 328 and the sliding groove 312. Both sets of connecting plates 327 extend out through the guide groove 313 and are fixedly connected to the first driving plate 325 and the second driving plate 326 respectively.

[0038] Furthermore: by rotating the knob 322 in the clamping assembly 32, the hinge block 323 is driven to rotate. The hinge block 323 pushes the drive plate 325 and the drive plate 326 outward through the two hinge holes 324. At the same time, the drive plate 325 and the drive plate 326 then drive the sliding blocks 328 on both sides to slide outward in the slide groove 312 through the connecting plates 327 on both sides. This drives the clamping plate 329 and the locking block 3210 on it to move outward. Then, by placing the grounding resistor body 2 through the positioning block 101, the locking seat 5 is set between the locking blocks 3210 on both sides. Then, the knob 322 is released. Under the action of the spring 3211, the locking block 3210 on the clamping plate 329 is locked into the locking seat 5 of the grounding resistor body 2, and the fixing is completed.

[0039] By employing a central hinge-driven bidirectional synchronous mechanical motion structure, the clamping blocks 3210 on both sides simultaneously and with equal force clamp the mounting base 5, avoiding problems such as unilateral force or tilted fixation, resulting in a more secure and reliable installation. Furthermore, a simple rotation of a single knob 322 synchronously drives the clamping mechanisms on both sides to fix or release the resistor, saving time and effort, eliminating the need for additional tools, effectively improving maintenance efficiency, and reducing maintenance time.

[0040] Reference Figure 5-6 As shown, specifically in this embodiment, the locking assembly 33 includes a limiting plate 333 slidably installed in the mounting groove 314, and a plug rod 331 fixedly connected to the limiting plate 333. A spring 334 sleeved on the plug rod 331 is fixedly connected between the limiting plate 333 and the mounting groove 314. A pull ring 332 is fixedly connected to the upper end of the plug rod 331. The lower end of the plug rod 331 passes through the L-shaped base plate 311 and is engaged with the center block 321. A matching slot 3212 is provided on the center block 321.

[0041] Furthermore: When the latching block 3210 in the clamping assembly 32 enters the latching seat 5 under the action of the first spring 3211, the slot 3212 on the center block 321 is aligned with the insert rod 331 in the locking assembly 33. Under the action of the second spring 334, the lower end of the insert rod 331 is inserted into the slot 3212, thereby fixing the center block 321 and locking the knob 322 to prevent the knob 322 from rotating due to vibration or accidental contact. To unlock, simply pull the pull ring 332 upwards.

[0042] Reference Figure 6 As shown, specifically in this embodiment, the buffer assembly 34 includes a top plate 341 fixedly installed on the mounting platform 1. A damper 342 and a buffer spring 343 are fixedly installed between the lower end of the top plate 341 and the bottom plate of the L-shaped base plate 311. The buffer spring 343 is sleeved on the outside of the damper 342.

[0043] Furthermore: the buffer spring 343 provides elastic support, and the damper 342 consumes vibration energy. When there is a strong external impact or vibration, the entire fixing mechanism can float slightly within the slot 103, thereby further protecting the grounding resistor body 2 and preventing the fixing point from being damaged due to rigid connection. Together with the vibration damping pad 102, it further improves the overall buffering effect.

[0044] The working principle of this utility model is as follows: the position of the grounding resistor is quickly determined by the two sets of positioning blocks 101 on the mounting platform 1, so that the locking seat 5 moves to the predetermined position. Then, by rotating the knob 322 in the clamping assembly 32, the hinge block 323 is driven to rotate. The hinge block 323 pushes the drive plate 1 325 and the drive plate 2 326 outward through the two hinge holes 324. At the same time, the drive plate 1 325 and the drive plate 2 326 then drive the sliding blocks 328 on both sides to slide outward in the slide groove 312 through the connecting plates 327 on both sides, thereby driving the clamping plate 329 and the locking block 3210 on it to move outward. Then, by placing the grounding resistor body 2 through the positioning block 101, the locking seat 5 is set between the locking blocks 3210 on both sides. Then, the knob 322 is released, and under the action of the spring 1 3211, the locking block 3210 on the clamping plate 329 is locked into the locking seat 5 of the grounding resistor body 2, thus completing the fixation.

[0045] After being fixed, the spring 334 of the locking assembly 33 pushes the limiting plate 333 to move downward, causing the lower end of the insertion rod 331 to pass through the L-shaped base plate 311 and be inserted into the slot 3212, locking the center block 321 and the knob 322 to prevent the knob 322 from rotating during subsequent use and to ensure a stable clamping state.

[0046] When it is necessary to disassemble or maintain the grounding resistor body 2, the operator pulls the pull ring 332 upwards. The pull ring 332 drives the insertion rod 331 and the limiting plate 333 to move upwards. The lower end of the insertion rod 331 disengages from the slot 3212, releasing the lock on the center block 321. Then, the knob 322 is turned to repeat the initial opening action, so that the locking block 3210 disengages from the locking seat 5. The grounding resistor body 2 can then be directly removed, completing the disassembly. The whole process does not require any additional tools, and the operation is convenient and efficient.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
