Description

Technical Field

[0001] The utility model belongs to the technical field of electrical construction, and in particular relates to a fastening device for electrical test wiring clamps. Background Art

[0002] The wiring clamp is a special clamp for temporary wiring when testing or repairing electrical equipment. When conducting electrical tests on high-voltage transformers, electrical testers need to use aerial work vehicles to clamp the electrical test wiring clamps on the transformer high-voltage bushing terminal block to complete the test wiring work. However, due to the interaction of forces, the wiring clamps can easily fall off and affect the electrical test, so the wiring clamps need to be tightened.

[0003] Existing wiring clamp fastening devices, such as the utility model patent with authorization announcement number CN217789001U, discloses an electrical test wiring clamp fastening device. The rotating connection mechanism can adjust the interval between the clamp and the vertical plate, thereby facilitating the clamping and disassembly of the wiring clamp. The circumferential rotation positioning of the knob is convenient and reliable, ensuring the clamping force of the wiring clamp.

[0004] However, the above mechanism clamps the wiring clamp by the supporting force of the spring. This elastic support method has a small clamping force and poor clamping stability. In addition, the above structure uses a large number of springs, sliders, and connecting rods, which not only makes the structure complex and inconvenient to assemble, but also is prone to damage due to too many parts. Utility Model Content

[0007] The beneficial effects of the utility model are as follows: an operator can pull the toggle clamp to make the clamping plate move stably under the support of the rotating handle and the guidance of the guide rod, and cooperate with the main support plate to firmly clamp the clamp body of the wiring clamp; the device has a simple structure, is not easy to be damaged, and is easy to operate.

[0008] In order to ensure the stability of the movement of the clamping plate;

[0009] As a further improvement of the above technical solution: the axis of the screw is parallel to the axis of the guide rod, and the number of the guide rods is multiple.

[0010] The beneficial effect of this improvement is that the multiple guide rods can provide stable limiting and guiding for the clamping plate and the movable plate, so that the clamping plate can move stably under the support of the screw rod.

[0011] In order to conveniently turn the screw to adjust the distance between the clamping plate and the moving plate;

[0012] As a further improvement of the above technical solution: a through hole structure with clearance fit with the screw rod is opened on the main support plate, and a rotating handle is installed at one end of the screw rod.

[0013] The beneficial effect of this improvement is that the operator can hold the handle and conveniently rotate the screw to change the distance between the clamping plate and the movable plate, so that the clamping plate can cooperate with the main support plate to clamp the wiring pliers with different clamp body widths.

[0014] In order to make the main support plate cooperate with the clamping plate to firmly clamp the clamp body of the wiring clamp;

[0015] As a further improvement of the above technical solution: the main support plate is a channel steel structure.

[0016] The beneficial effect of this improvement is that the clamping plate can cooperate with a side wing plate of the main support plate to firmly clamp the clamp body of the wiring clamp.

[0017] To firmly hold the wire clamp;

[0018] As a further improvement of the above technical solution: the end surface of the clamping plate facing away from the movable plate is a smooth plane structure, and the end surface of the clamping plate facing away from the movable plate is parallel to the inner side surface of the main support plate.

[0019] The beneficial effect of this improvement is that the clamping plate can move parallel to the two sides of the main support plate, thereby firmly clamping the clamp body of the wiring clamp.

[0020] In order to ensure a stable connection between the pressure head of the toggle clamp and the moving plate;

[0021] As a further improvement of the above technical solution: the movable plate is arranged between the head of the bolt and the nut, and the pressure head of the toggle clamp is provided with an internal threaded hole structure for threaded connection with the bolt.

[0022] The beneficial effect of this improvement is that under the clamping of the bolt and the nut, the pressure head of the toggle clamp can drive the moving plate to move stably.

When the operator pulls the toggle clamp 4, the clamping plate 7 can be stably moved under the support of the turning handle 8 and the guidance of the guide rod 2, and the clamp body of the wiring clamp can be firmly clamped with the main support plate 1; the device structure is simple and not easy to damage, and the operation is convenient; the axis of the screw rod 6 is parallel to the axis of the guide rod 2, and the number of the guide rods 2 is multiple, and the multiple guide rods 2 can provide stable limit and guidance for the clamping plate 7 and the moving plate 5, so that the clamping plate 7 is fixed on the screw rod 6 The main support plate 1 is provided with a through hole structure which is clearance matched with the screw rod 6. A turning handle 8 is installed at one end of the screw rod 6. The operator can hold the turning handle 8 to conveniently turn the screw rod 6 to change the distance between the clamping plate 7 and the movable plate 5, so that the clamping plate 7 can cooperate with the main support plate 1 to clamp the wiring clamp with different clamp body widths. The main support plate 1 is a channel steel structure. The clamping plate 7 can cooperate with a side wing plate of the main support plate 1 to firmly clamp the clamp body of the wiring clamp. The back of the clamping plate 7 One end surface of the movable plate 5 is a smooth plane structure, and the end surface of the clamping plate 7 facing away from the movable plate 5 is parallel to the inner side surface of the main support plate 1. The clamping plate 7 can move parallel to both sides of the main support plate 1, thereby firmly clamping the clamp body of the wiring clamp.
