Description

Technical Field

[0001] This utility model belongs to the field of high-voltage wire harness technology, and in particular relates to an adjustable anti-loosening high-voltage wire clamp. Background Technology

[0002] The high-voltage wiring harness assembly consists of a high-voltage connector, a high-voltage cable, a corrugated tube, double-wall heat shrink tubing, self-locking tape, and labels. A high-voltage cable clamp is a specialized clamp used after cable laying and installation to secure the cable, ensuring it is in the correct position and preventing movement due to external force or its own weight.

[0003] In the construction and maintenance of high-voltage transmission lines, wire clamps are crucial components for securing conductors. Existing wire clamps often lack adjustment capabilities or have complex adjustment processes, making installation and maintenance difficult under varying conditions. Utility Model Content

[0004] This utility model addresses the problem that existing wire clamps often lack adjustment functionality or have complex adjustment processes, and proposes the following technical solution:

[0005] An adjustable anti-loosening high-voltage wire clamp includes a base, a lower clamping block disposed on the top of the base, an upper clamping block disposed on the upper surface of the lower clamping block, an adjustment component disposed inside the base, and a positioning component disposed outside the base.

[0006] The adjustment assembly includes a bidirectional threaded rod, a threaded block, a connecting block, an insulating connecting seat, a knob, and a slider. The threaded block is threaded to the outside of the bidirectional threaded rod, the connecting block is fixedly connected to the top of the threaded block, the insulating connecting seat is fixedly connected to the top of the connecting block, and the knob is rotatably connected to the outside of the base.

[0007] The positioning component includes a positioning frame, a guide rod, a movable block, a mounting hole, a positioning hole, and an abutment rod. The guide rod is fixedly connected to the inside of the positioning frame, the movable block is slidably connected to the outside of the guide rod, the mounting hole is opened inside the movable block, the positioning hole is opened inside the positioning frame, and the abutment rod is threadedly connected to the inside of the positioning hole and abuts against the outer wall of the movable block.

[0008] With the adjustable spacing of the adjustment component, the distance between the two lower clamps can be easily adjusted to a suitable position for the cable to accommodate high-voltage cables of different specifications. With the quick connection of the connection component, the lower clamp and the upper clamp can be quickly connected. At the same time, with the elasticity of the abutment spring, the upper clamp will not loosen during use, preventing the cable from loosening and falling off, thus improving the stability and safety of the line.

[0009] As a preferred embodiment of the above technical solution, the bidirectional threaded rod is rotatably connected to the interior of the base and extends to its exterior, with the end of the bidirectional threaded rod away from the base being fixedly connected to the knob.

[0010] Driven by the knob, the bidirectional threaded rod rotates in both directions.

[0011] As a preferred embodiment of the above technical solution, the number of the threaded block, the connecting block, the insulating connecting seat and the slider are all two, and the number of the lower clamping block and the upper clamping block are both two, with the two lower clamping blocks respectively fixedly connected to the upper surfaces of the two insulating connecting seats.

[0012] Under the transmission action of the bidirectional threaded rod, the two threaded blocks respectively drive the connecting block to approach or separate from the insulating connecting seat.

[0013] As a preferred embodiment of the above technical solution, the base has a movable opening inside that matches the connecting block, the slider is fixedly connected to the bottom of the threaded block and extends into the interior of the base, the base has a sliding groove inside that matches the slider, and the slider and the sliding groove are slidably connected.

[0014] The limiting effect of the slide and the slider improves the stability of the two lower clamping blocks during movement adjustment.

[0015] As a preferred embodiment of the above technical solution, the positioning frame is fixedly connected to the outside of the base, there are two guide rods, the moving block is slidably connected to the inside of the positioning frame through the guide rods, the outer diameter of the moving block is adapted to the inner diameter of the positioning frame, and there are several positioning holes, which are distributed at equal intervals inside the positioning frame.

[0016] Guided by the guide rod, the moving block can quickly adjust its position inside the positioning frame, allowing the base to be quickly positioned and fixed.

[0017] As a preferred embodiment of the above technical solution, a connecting component is provided on the outside of both lower clamping blocks and the upper clamping block. The connecting component includes a mounting block, a screw, a rotating disk, and a contact spring. There are four mounting blocks, which are symmetrically distributed on the outside of the lower clamping blocks and the upper clamping blocks.

[0018] The use of the positioning hole and the abutment rod improves the fixing effect after the moving block is adjusted.

[0019] As a preferred embodiment of the above technical solution, the screw is rotatably connected to the upper surface of the top mounting block and extends into the interior of the bottom mounting block, the rotating disk is fixedly connected to the top end of the screw, and the abutment spring is fixedly connected to the bottom of the rotating disk and surrounds the outside of the screw.

[0020] The elastic action of the retaining spring ensures that the upper clamp will not loosen during use.

[0021] The beneficial effects of this utility model are as follows:

[0022] (1) Under the adjustment of the spacing of the adjustment component, the spacing between the two lower clamps can be easily adjusted to a suitable position for the cable to adapt to high voltage cables of different specifications. Under the quick connection of the connection component, the lower clamp and the upper clamp can be quickly connected. At the same time, under the elastic action of the abutment spring, the upper clamp will not loosen during use, preventing the cable from loosening and falling off, and improving the stability and safety of the line.

[0023] (2) Under the movement of the positioning component, the moving block can quickly adjust its position, so that the base can be quickly positioned and fixed, thus significantly improving the installation efficiency. Installers can quickly and accurately fix the high-voltage cable, reducing installation time and cost. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0030] Example

[0031] Figures 1 to 4 The diagram shown is a structural schematic of a specific embodiment of this utility model. An adjustable anti-loosening high-voltage wire clamp includes a base 1, a lower clamping block 2 disposed on the top of the base 1, an upper clamping block 3 disposed on the upper surface of the lower clamping block 2, an adjustment component 4 disposed inside the base 1, and a positioning component 5 disposed outside the base 1. The adjustment component 4 includes a bidirectional threaded rod 41, a threaded block 42, a connecting block 43, an insulating connecting seat 44, a knob 45, and a slider 46. The threaded block 42 is threadedly connected to the outside of the bidirectional threaded rod 41, the connecting block 43 is fixedly connected to the top of the threaded block 42, the insulating connecting seat 44 is fixedly connected to the top of the connecting block 43, and the knob 45 is rotatably connected to the outside of the base 1.

[0032] The bidirectional threaded rod 41 is rotatably connected to the inside of the base 1 and extends to its outside. The end of the bidirectional threaded rod 41 away from the base 1 is fixedly connected to the knob 45.

[0033] Driven by the knob 45, the bidirectional threaded rod 41 rotates in both directions.

[0034] Specifically, there are two threaded blocks 42, two connecting blocks 43, two insulating connecting seats 44 and two sliders 46. There are two lower clamping blocks 2 and two upper clamping blocks 3. The two lower clamping blocks 2 are fixedly connected to the upper surfaces of the two insulating connecting seats 44 respectively.

[0035] The insulation effect of the insulating connector 44 improves the overall insulation effect of the device. Under the drive of the bidirectional threaded rod 41, the two threaded blocks 42 drive the connector 43 to approach or separate from the insulating connector 44 respectively. The distance between the two lower clamping blocks 2 can be easily adjusted to a suitable position for the cable to adapt to high-voltage cables of different specifications.

[0036] It should be noted that the base 1 has a movable opening inside that matches the connecting block 43. The slider 46 is fixedly connected to the bottom of the threaded block 42 and extends into the interior of the base 1. The base 1 has a sliding groove inside that matches the slider 46. The slider 46 and the sliding groove are slidably connected.

[0037] The limiting effect of the slide groove and slider 46 improves the stability of the two lower clamping blocks 2 during movement adjustment, ensuring the stability of the cable under high voltage environment.

[0038] Figure 1 and Figure 3In the positioning component 5, there are positioning frame 51, guide rod 52, moving block 53, mounting hole 54, positioning hole 55, and abutting rod 56. The guide rod 52 is fixedly connected to the inside of the positioning frame 51, the moving block 53 is slidably connected to the outside of the guide rod 52, the mounting hole 54 is opened inside the moving block 53, the positioning hole 55 is opened inside the positioning frame 51, and the abutting rod 56 is threadedly connected to the inside of the positioning hole 55 and abuts against the outer wall of the moving block 53.

[0039] Guided by the guide rod 52, the movable block 53 can quickly adjust its position inside the positioning frame 51, so that the base 1 can be quickly positioned and fixed. Therefore, the installation efficiency can be significantly improved, and the installer can quickly and accurately fix the high-voltage cable, reducing installation time and cost.

[0040] The positioning frame 51 is fixedly connected to the outside of the base 1. There are two guide rods 52. The moving block 53 is slidably connected to the inside of the positioning frame 51 through the guide rods 52. The outer diameter of the moving block 53 is matched with the inner diameter of the positioning frame 51. There are several positioning holes 55, which are distributed at equal intervals inside the positioning frame 51.

[0041] The use of positioning hole 55 and abutment rod 56 improves the fixing effect of moving block 53 after position adjustment and prevents loosening.

[0042] Figure 4 In the middle, the two lower clamping blocks 2 and the upper clamping block 3 are each provided with a connecting component 6. The connecting component 6 includes a mounting block 61, a screw 62, a rotating disk 63, and a stop spring 64. There are four mounting blocks 61, which are symmetrically distributed on the outside of the lower clamping blocks 2 and the upper clamping blocks 3.

[0043] With the quick connection function of the connecting component 6, the lower clamping block 2 and the upper clamping block 3 can be quickly connected.

[0044] The screw 62 is rotatably connected to the upper surface of the top mounting block 61 and extends into the interior of the bottom mounting block 61. The rotating disk 63 is fixedly connected to the top of the screw 62, and the abutment spring 64 is fixedly connected to the bottom of the rotating disk 63 and surrounds the outside of the screw 62.

[0045] By rotating the rotating disk 63, the screw 62 moves downward, which can quickly connect and fix the two mounting blocks 61, thereby quickly connecting the lower clamping block 2 and the upper clamping block 3. At the same time, under the elastic action of the abutment spring 64, it is ensured that the upper clamping block 3 will not loosen during use, preventing the cable from loosening and falling off, and improving the stability and safety of the line.

[0046] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
