Description

Technical Field

[0001] This utility model belongs to the field of power testing technology, and in particular relates to an insulating support device for power testing. Background Technology

[0002] Insulating support devices for power testing are an important component in ensuring the safe operation of power systems. Their main function is to provide physical isolation in power equipment to prevent current leakage, etc.

[0003] When conducting electrical testing, testers use insulating devices and need to touch them by hand. However, the output voltage of the test equipment being tested often exceeds the voltage that the human body can withstand, posing a certain danger to the testers. A voltage-applying lead is necessary to ensure the safety of the testers. Furthermore, in severe weather during electrical testing, the insulating rods in the insulating device may fall, requiring constant monitoring by the testers. Therefore, we provide an insulating support device for electrical testing. Utility Model Content

[0004] The purpose of this utility model is to provide an insulating support device for power testing. It uses a tension fixing block and a rotation fixing block to fix the support crossbar. Pulling the limiting movable rod causes the limiting ring to compress the spring, pushing the tension rod to bring the tension fixing block to its maximum limit position. Rotating the screw rod moves the rotation fixing block to the position where it clamps the support crossbar. This solves the problem that power testing personnel face certain dangers, requiring the use of pressure leads to ensure their safety, and that the insulating rod may fall when using an insulating device, necessitating constant monitoring by the testing personnel.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an insulating support device for power testing, including a device base, a lifting component is arranged at the center of the upper part of the device base, a support component is arranged above the lifting component, the lifting component includes a column, a lifting rod is slidably connected inside the column, a sliding component is arranged at the top of the device base, the sliding component includes a bidirectional threaded rod, the two threads on the outer surface of the bidirectional threaded rod are arranged in opposite directions, and two sliding blocks are threadedly connected to the outer surface of the bidirectional threaded rod.

[0007] The support assembly includes a fixed plate, on the front of which are fixedly connected several support crossbars. The support crossbars are connected to identical parts. A tension fixing block contacts the left side of each support crossbar, and a rotating fixing block contacts the right side of each support crossbar. A first limiting rod is provided on the right side of the rotating fixing block, and a second limiting rod is provided on the left side of the tension fixing block. A limiting movable rod is slidably connected inside the second limiting rod, and a limiting ring is fixedly connected to the inner wall of the limiting movable rod. A spring is sleeved on the outer side of the limiting movable rod. A screw rod is threadedly connected inside the first limiting rod. V-grooves are formed on corresponding sides of both the tension fixing block and the rotating fixing block. These V-grooves help to better fix the support crossbars, providing good support and preventing them from falling off.

[0008] Furthermore, each of the four corners of the tension fixing block and the rotation fixing block is slidably connected to a fixing rod two. The left side of the four fixing rod two is fixedly connected to the right side of the limiting rod two, and the right side of the four fixing rod two is fixedly connected to the left side of the limiting rod one. A tension rod is slidably connected at the center of the limiting rod two. The front of the tension rod has several slots. The tension rod is slidably connected inside the limiting rod two. Several slots are opened on the surface of the tension rod to ensure that the tension fixing block will not slide and to ensure that the tension fixing block can better fix the support crossbar.

[0009] Furthermore, fixed blocks are fixedly connected to both the left and right sides of the lifting rod, and support rods are provided on both the left and right sides of the lifting rod. Pins are rotatably connected to the top and bottom of the two support rods. The top of the support rod is rotatably connected to the fixed block through the pin, and the bottom of the support rod is rotatably connected to the fixed column through the pin. The use of pins allows the support rod to rotate better, thereby facilitating the raising or lowering of the lifting rod.

[0010] Furthermore, the top of the device base has two movable slots, and the left and right sides of the bidirectional threaded rod are rotatably connected to limit columns. The bottom of the two limit columns is fixedly connected to the top of the device base. When the bidirectional threaded rod is rotated clockwise, the two sliding blocks can slide close together. When the bidirectional threaded rod is rotated counterclockwise, the two sliding blocks can slide repelling each other.

[0011] Furthermore, the two sliding blocks are connected to the same parts. Two sliding columns are fixedly connected to the bottom of the sliding block, and a fixed column is fixedly connected to the center of the top of the sliding block. An internal hexagon head is fixedly connected to the left side of the bidirectional threaded rod. The sliding columns can move in the movable slot. When the two sliding columns are close together, the lifting rod is raised through the support rod. When the two sliding columns are far apart, the lifting rod is lowered through the support rod.

[0012] Furthermore, the back of the first limiting rod is fixedly connected to the front of the fixing plate, and the back of the second limiting rod is fixedly connected to the front of the fixing plate. V-grooves are provided on the corresponding sides of the tension fixing block and the rotation fixing block. The fixing rod allows the rotation fixing block and the tension fixing block to slide on its surface, thereby achieving clamping when the support crossbar needs to be clamped and releasing when the support crossbar needs to be released.

[0013] Furthermore, the bottom outer surface of the sliding column is in contact with the surface of the movable groove, the top of the support rod is rotatably connected to the fixed block through a pin, and the bottom of the support rod is rotatably connected to the fixed column through a pin. The sliding column slides in the movable groove, and there is a limiting column on the surface of the movable groove to prevent the sliding column from exceeding the limit.

[0014] Furthermore, the front of the limiting ring is fixedly connected to the back of the spring, the front of the spring is fixedly connected to the front of the inner wall of the second limiting rod, the tension rod is fixedly connected to the tension fixing block, and the screw rod is rotatably connected to the rotating fixing block. Under the action of the limiting ring and the spring, the limiting movable rod can ensure that the tension rod does not slide during use, and similarly, it can also ensure that the tension rod does not slide when not in use.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model solves the problem of the support crossbar falling by setting up a support component, specifically by using a tension fixing block and a rotation fixing block to fix the support crossbar. Pulling the limit movable rod drives the limit ring to squeeze the spring, pushes the tension rod to make the tension fixing block reach the maximum limit position, and rotates the screw rod to move the rotation fixing block to the position to clamp the support crossbar. This solves the problem of the support crossbar falling, and the test personnel do not need to worry about the support crossbar falling afterward.

[0017] 2. This utility model incorporates a lifting device. Specifically, rotating the hexagonal head clockwise brings the sliding block and the limiting column closer together, thereby raising the lifting rod and bringing the support assembly to the position to be tested. When the test is finished, rotating the hexagonal head counterclockwise moves the sliding block and the limiting column away from each other, thereby lowering the lifting rod and preventing damage to the lifting rod.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6As shown, an insulating support device for power testing includes a device base 1, a lifting assembly 2 is arranged at the center of the upper part of the device base 1, a support assembly 3 is arranged above the lifting assembly 2, the lifting assembly 2 includes a column 211, a lifting rod 212 is slidably connected inside the column 211, a sliding assembly 4 is arranged at the top of the device base 1, the sliding assembly 4 includes a bidirectional threaded rod 411, the two threads on the outer surface of the bidirectional threaded rod 411 are arranged in opposite directions, and two sliding blocks 413 are threadedly connected to the outer surface of the bidirectional threaded rod 411.

[0030] Support assembly 3 includes a fixed plate 311. Several support crossbars 317 are fixedly connected to the front of the fixed plate 311. The parts connected to the support crossbars 317 are identical. A tension fixing block 314 contacts the left side of each support crossbar 317, and a rotating fixing block 320 contacts the right side of each support crossbar 317. A first limit rod 313 is provided on the right side of the rotating fixing block 320. A second limit rod 316 is provided on the left side of the tension fixing block 314. A limit movable rod 318 is slidably connected inside the second limit rod 316. A limit ring 321 is fixedly connected to the inner wall of the limit movable rod 318. The outer side of the limit movable rod 318... The side sleeve is equipped with a spring 322, and the internal thread of the limiting rod 313 is connected to the screw rod 312. Specifically, the support crossbar 317 is fixed by stretching the fixing block 314 and the fixing block 320. Pulling the limiting movable rod 318 causes the limiting ring 321 to compress the spring 322, pushing the stretching rod 315 to make the stretching fixing block 314 reach the maximum limit position. Rotating the screw rod 312 makes the fixing block 320 move to the position of clamping the support crossbar 317. This solves the problem of the support crossbar 317 falling off, and the test personnel do not need to worry about the support crossbar 317 falling off afterward.

[0031] The four corners of the tension fixing block 314 and the rotation fixing block 320 are slidably connected with fixing rods 319. The left side of the four fixing rods 319 is fixedly connected to the right side of the limiting rod 316, and the right side of the four fixing rods 319 is fixedly connected to the left side of the limiting rod 313. The center of the limiting rod 316 is slidably connected with a tension rod 315. The front of the tension rod 315 has several slots.

[0032] The lifting rod 212 is fixedly connected to the left and right sides with fixing blocks. The lifting rod 212 is also provided with support rods 213 on the left and right sides. The top and bottom of the two support rods 213 are rotatably connected with pins 215. Specifically, the hexagonal head 414 is rotated clockwise to bring the sliding block 413 and the limiting column 412 closer together, thereby driving the lifting rod 212 to rise and the support assembly 3 to the position to be tested. When the test is over, the hexagonal head 414 is rotated counterclockwise to move the sliding block 413 and the limiting column 412 away from each other, thereby causing the lifting rod 212 to fall down and preventing damage to the lifting rod 212.

[0033] The top of the device base 1 has two movable slots 416. The left and right sides of the bidirectional threaded rod 411 are rotatably connected to the limit column 412. The bottom of the two limit columns 412 are fixedly connected to the top of the device base 1.

[0034] The two sliding blocks 413 are connected to the same parts. The bottom of the sliding block 413 is fixedly connected to two sliding columns 415, and the top center of the sliding block 413 is fixedly connected to a fixed column 214. The left side of the bidirectional threaded rod 411 is fixedly connected to an internal hex head 414.

[0035] The back of limit rod 313 is fixedly connected to the front of the fixing plate 311, and the back of limit rod 316 is fixedly connected to the front of the fixing plate 311. V-grooves are provided on the corresponding sides of the tension fixing block 314 and the rotation fixing block 320.

[0036] The bottom outer surface of the sliding column 415 contacts the surface of the movable groove 416. The top of the support rod 213 is rotatably connected to the fixed block through the pin 215, and the bottom of the support rod 213 is rotatably connected to the fixed column 214 through the pin 215.

[0037] The front of the limiting ring 321 is fixedly connected to the back of the spring 322, the front of the spring 322 is fixedly connected to the front of the inner wall of the second limiting rod 316, the tension rod 315 is fixedly connected to the tension fixing block 314, and the screw rod 312 is rotatably connected to the rotating fixing block 320.

[0038] One specific application of this embodiment is:

[0039] During use, the tester first supports and fixes the crossbar 317. Pulling the limiting rod 318 outward causes the limiting ring 321 to move, thus compressing the spring 322. This pushes the tension rod 315, causing the tension fixing block 314 to slide on the fixing rod 319 until it reaches the fixed support position of the crossbar 317. Releasing the limiting rod 318 causes the spring 322 to return to its original position due to compression. The limiting rod 318 then resets due to the elasticity of the spring 322. The tension fixing block 314 is then pushed for fine-tuning, allowing the limiting rod 318 to smoothly enter the slot on the tension rod 315, thus extending the tension. With the fixing block 314 secured, sliding the tension fixing block 314 reduces the number of times the screw rod 312 needs to be rotated, reducing labor costs and improving installation efficiency. Then, using a wrench to rotate the screw rod 312 clockwise causes the fixing block 320 to slide onto the fixing rod 319 until it reaches the position of the fixing sleeve 316. The fixing block 320, in conjunction with the tension fixing block 314, clamps and secures the support crossbar 317, providing good support and preventing it from falling. Furthermore, the tension fixing block... The corresponding side of the fixed block 314 and the fixed block 320 is provided with a V-groove, which can further improve the fixing effect. When the insulating support device needs to be tested at a certain height, the height of the lifting rod 212 can be adjusted by turning the hexagonal head 414 clockwise or counterclockwise with a hex wrench. When it needs to be raised, turning the hexagonal head 414 clockwise will cause the two sliding blocks 413 to slide on the double-threaded rod 411 and move closer to each other. The two sliding columns 415 slide closer to each other through the movable groove 416. Since the sliding columns 415 slide in the movable groove 416, it can... The sliding block 413 is limited, causing it to move linearly. When the two sliding blocks 413 approach each other, the bottoms of the two support rods 213 will approach each other through the fixed column 214. The tops of the two support rods 213 will then drive the lifting rod 212 to move upward, enabling the lifting rod 212 to rise. When the work is finished, the internal hex head 414 is rotated counterclockwise, causing the sliding blocks 413 to slide against each other on the bidirectional threaded rod 411. Similarly, the two sliding columns 415 slide against each other in the movable groove 416. The bottoms of the two support rods 213 slide against each other, causing the lifting rod 212 to descend.
