Description

Technical Field

[0001] This application belongs to the technical field of electrical testing equipment, and more specifically, relates to an electrical conduit fixing device. Background Technology

[0002] Based on relevant standards, the insulation strength test of electrical conduits requires the conduit to be fixed in a U-shape. Current technologies typically employ mechanical locking or elastic clamping to lock and fix both ends of the conduit. Mechanical locking primarily applies mechanical pressure to the outer wall of the conduit through a rigid structure; however, its locking diameter is strictly limited, thus it is only suitable for conduits of specific specifications. Elastic clamping relies on the deformation and rebound force of elastic elements to achieve adaptive clamping. Its clamping force stability is limited by the strong coupling relationship between the conduit material's deformation characteristics and its diameter, thus it is also only suitable for conduits with specific deformation characteristics and specifications. It can be seen that both fixing methods require frequent replacement of locking or clamping components during cross-specification testing, affecting testing efficiency. Utility Model Content

[0003] The purpose of this application is to provide an electrical conduit fixing device, which aims to solve the problem that current mechanical locking or elastic clamping fixing methods require frequent replacement of incompatible locking or clamping components during cross-specification testing, thus affecting testing efficiency.

[0004] To achieve the above objectives, the technical solution adopted in this application is to provide an electrical conduit fixing device, including a bracket assembly and a plurality of clamping units disposed on the bracket assembly. Each clamping unit includes a connecting support, a first bolt, a first clamp, a second bolt, and a second clamp. The connecting support is disposed on the bracket assembly. The first bolt is threadedly connected to the connecting support and rotatably connected to the first clamp. The second bolt is threadedly connected to the connecting support and rotatably connected to the second clamp. The first bolt and the second bolt are spaced apart relative to each other along the same axial direction. The first clamp is located at the end of the first bolt facing the second bolt, and the second clamp is located at the end of the second bolt facing the first bolt.

[0005] In one embodiment, the connecting support includes a movable connecting part, a first fixing part, a first limiting part, a second fixing part, and a second limiting part. The movable connecting part is movably connected to the bracket assembly in a vertical direction. The first limiting part is fixedly connected to the movable connecting part and the first fixing part. A first bolt is threadedly connected to the first fixing part. The first limiting part is used to limit the rotation range of the first gripper around the first bolt. The second limiting part is fixedly connected to the movable connecting part and the second fixing part. A second bolt is threadedly connected to the second fixing part. The second limiting part is used to limit the rotation range of the second gripper around the second bolt.

[0006] In one embodiment, the first gripper has a first curved groove on the side facing the second gripper, and the second gripper has a second curved groove on the side facing the first gripper.

[0007] In one embodiment, a first anti-slip pad is adapted to be provided on the first curved groove, and a second anti-slip pad is adapted to be provided on the second curved groove. Both the first anti-slip pad and the second anti-slip pad are provided with anti-slip friction texture.

[0008] In one embodiment, the support assembly includes a bottom frame, a top frame, and multiple support columns and multiple connecting columns fixedly connected between the bottom frame and the top frame in a vertical direction. Each movable connecting part of each clamping unit is movably sleeved on each connecting column in a vertical direction.

[0009] In one embodiment, the connecting column is provided with a plurality of positioning screw holes at equal intervals along the vertical direction, and the connecting support also includes positioning bolts, which are inserted into the corresponding movable connecting parts and used for threaded connection to any positioning screw hole in the corresponding connecting column.

[0010] The beneficial effect of the electrical conduit fixing device provided in this application is that, compared with the prior art, the above-mentioned electrical conduit fixing device includes a support assembly and multiple clamping units disposed on the support assembly. Each clamping unit includes a connecting support, a first bolt, a first clamp, a second bolt, and a second clamp. The connecting support is disposed on the support assembly. The first bolt is threaded to the connecting support and rotatably connected to the first clamp. The second bolt is threaded to the connecting support and rotatably connected to the second clamp. The first bolt and the second bolt are spaced apart relative to each other along the same axial direction. The first clamp is located directly opposite the first bolt. With the second clamp located at one end of the second bolt facing the end of the first bolt, in cross-specification testing of the insulation strength of electrical conduits, the distance between the first and second bolts in each clamping unit can be adjusted according to the different sizes of electrical conduits. This allows the first and second clamps to come closer together and clamp the electrical conduits of the corresponding sizes, avoiding the problem of frequent replacement of clamping or holding components due to the limitations of existing fixing methods on the size and material deformation characteristics of electrical conduits, thus improving testing efficiency.

The electrical conduit fixing device 10 includes a support assembly 100 and a plurality of clamping units 200 disposed on the support assembly 100. Each clamping unit 200 includes a connecting support 210, a first bolt 220, a first clamp 230, a second bolt 240, and a second clamp 250. The connecting support 210 is disposed on the support assembly 100. The first bolt 220 is threadedly connected to the connecting support 210 and rotatably connected to the first clamp 230. The second bolt 240 is threadedly connected to the connecting support 210 and rotatably connected to the first clamp 250. The second clamp 250 is connected, and the first bolt 220 and the second bolt 240 are arranged opposite each other along the same axis. The first clamp 230 is located at the end of the first bolt 220 facing the second bolt 240, and the second clamp 250 is located at the end of the second bolt 240 facing the first bolt 220. By rotating the first bolt 220 and the second bolt 240 respectively, the first clamp 230 and the second clamp 250 can be brought closer or moved away from each other. By rotating the first clamp 230 and the second clamp 250 to an appropriate angle, they can be used to clamp and fix electrical conduits of different specifications and sizes.

[0022] The beneficial effect of the electrical conduit fixing device 10 provided in this application is that, compared with the prior art, the electrical conduit fixing device 10 of this application includes a bracket assembly 100 and a plurality of clamping units 200 disposed on the bracket assembly 100. Each clamping unit 200 includes a connecting support 210, a first bolt 220, a first clamp 230, a second bolt 240, and a second clamp 250.

The first clamp 230 is located at the end of the first bolt 220 facing the second bolt 240, and the second clamp 250 is located at the end of the second bolt 240 facing the first bolt 220. In this way, for cross-specification testing of the insulation strength of electrical conduits, the distance between the first bolt 220 and the second bolt 240 in each clamping unit 200 can be adjusted according to the size specifications of different electrical conduits. This allows the first clamp 230 and the second clamp 250 to come closer together and clamp and fix the electrical conduits of the corresponding size specifications. This avoids the problem that the existing fixing method is limited by the size specifications of the electrical conduits and the deformation characteristics of the materials, which leads to the need to frequently replace the clamping or holding components, thereby effectively improving the testing efficiency.
