Description

Technical Field

[0001] This utility model relates to the field of wire and cable testing technology, specifically to a wire and cable heat resistance testing device with a fixed structure. Background Technology

[0002] Wires and cables refer to materials used for power, electrical, and related transmission purposes. There is no strict boundary between "wires" and "cables." Generally, products with fewer cores, smaller diameters, and simpler structures are called wires, while those without insulation are called bare wires, and others are called cables. Those with larger conductor cross-sectional areas are called large cables, and those with smaller cross-sectional areas are called small wires or building wires.

[0003] After the production of wires and cables, their heat resistance needs to be tested. For example, the heat resistance testing equipment for wires and cables with a fixed structure, as disclosed in announcement number "CN221100568U", works by pressing a fixed push plate backward. This causes the fixed push plate to move a sliding block backward, at which point the return spring contracts and shortens. Since the side of the sliding block and the rear end of the connecting diagonal rod are hinged together, and the front end of the connecting diagonal rod and the rear end of the clamping base plate are hinged together, when the sliding block moves backward, the two batches of fixed components will move closer together. Then, the two ends of the wire and cable are placed inside the two batches of fixed components, and the fixing bolts are screwed down. The clamping top plate moves downward, thus fixing and clamping the wire and cable. After releasing the fixed push plate, the sliding block moves forward due to the elastic force of the return spring, causing the two batches of fixed components to move away from each other. At this point, the wire and cable between the two batches of fixed components will be straightened. Finally, the heating wire heater is turned on, and the heat resistance of the wire and cable can be tested.

[0004] However, in actual use, the staff needs to hold the fixed push plate with their hands while placing the wires and cables between the clamping bottom plate and the clamping top plate, and then tighten them with fixing bolts. This is difficult for a single person to operate and is not efficient. Therefore, we propose a wire and cable heat resistance testing device with a fixed structure. Utility Model Content

[0005] The purpose of this invention is to provide a testing device for the heat resistance performance of wires and cables with a fixed structure, which can be operated by a single person and is highly efficient.

[0006] The specific technical solution adopted by this utility model is as follows: A device for testing the heat resistance of electrical wires and cables with a fixed structure includes a testing assembly. The testing assembly consists of a support base and a heating wire heater. Two sets of clamping mechanisms are disposed on the top of the support base, clamping the electrical wire and cable between the two sets of clamping mechanisms. A control unit for driving the clamping mechanisms is disposed on the top of the support base. The control unit includes a control slider, which is slidably mounted on the top of the support base. A support rod is hinged to the side of the control slider, and the end of the support rod away from the control slider is connected to the clamping mechanism. A contact spring is fixed to the side of the control slider near the heating wire heater. The end of the control slider away from the control slider is fixed to the support base. An L-shaped support rod is fixed to the top of the support base. A locking rod is provided on the L-shaped support rod. The locking rod passes through the L-shaped support rod and is slidably connected to the L-shaped support rod. A return spring is fixed to the top of the L-shaped support rod. The end of the return spring away from the L-shaped support rod is fixed to the locking rod. A slot is opened on the top of the control slider. The locking rod can be inserted into the slot to limit the control slider. This allows the operator to operate the control slider without constantly holding it. They only need to pass the wire and cable through the clamping mechanism. It can be operated by a single person, is convenient to use, and effectively improves the overall work efficiency.

[0007] This utility model also includes the following features: The clamping mechanism includes a clamping base plate, which is slidably mounted on the top of the support base. A fixing rod is fixed to the top of the clamping base plate, and the fixing rod passes through and is slidably connected to the clamping top plate. A connecting spring is fixed to the top of the clamping top plate, and the end of the connecting spring away from the clamping top plate is fixed to the fixing rod. Clamping holes are provided at the bottom of the clamping top plate and the top of the clamping base plate. A rubber pad is fixed to the inside of the clamping hole. The downward force exerted by the connecting spring on the clamping top plate allows the clamping top plate to keep in contact with the clamping base plate to clamp the wires and cables. During clamping, the rubber pad is squeezed to further improve the fixing effect.

[0008] One end of the support rod connected to the clamping mechanism is hinged to the side of the clamping base plate near the control slider. By pulling the control slider, the control slider can pull the clamping base plate and the clamping top plate to move closer to or further away from the center of the support base, thereby taut and straightening the wires and cables.

[0009] The electric heating wire heater is embedded in the top of the support base. The top of the support base has a horizontal sliding groove for two sets of clamping base plates to slide left and right, and a vertical sliding groove for controlling the slider to move back and forth.

[0010] The clamping top plate has a bottom support, the clamping bottom plate has a top support, and the supporting base has a front support. Each support includes a contact hole at the bottom and top of the clamping top plate. A bracket is fixed to the front of the supporting base. Two sets of brackets are symmetrically arranged on the front of the supporting base, and a crossbar is fixed between the two sets of brackets. The crossbar passes through two sets of protrusions and is fixedly connected to the protrusions. When the clamping top plate and clamping bottom plate move towards the center of the supporting base to the position of the protrusions, the protrusions can insert into the contact holes between the clamping top plate and clamping bottom plate, thereby opening the clamping top plate and clamping bottom plate and loosening the fixation of the wires and cables. Workers can then remove the inspected wires and cables and place new ones.

[0011] The bottom of the lever is sloped near the control slider. When the control slider moves towards the lever and touches it, the lever is pushed upward by the slope at the bottom. When the slot at the top of the control slider moves to the position of the lever, the lever can move downward and insert into the slot under the action of the return spring, thus limiting the control slider.

[0012] The technical advantages achieved by this utility model are as follows: Through the control unit, clamping mechanism, and supporting member, the two sets of clamping mechanisms can move towards or away from each other by pushing the control slider. When the two sets of clamping mechanisms move towards each other, the locking lever can limit the control slider, so that the operator does not need to hold the control slider all the time. At the same time, the protrusion can open the clamping base plate and clamping top plate. At this time, the operator only needs to pass the wire or cable through the clamping mechanism. It can be operated by a single person. After placement, simply pull the locking lever to release the limitation on the control slider, so that the two sets of clamping mechanisms can clamp the wire or cable and move away from each other at the same time to straighten the wire or cable. It is convenient to use and effectively improves the overall work efficiency. Attached Figure Description

It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model. As used herein, the terms "parallel" and "perpendicular" are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors. Combination Figures 1 to 4 As shown below, the specific features of this wire and cable heat resistance testing equipment with a fixed structure are described in detail: A test device for testing the heat resistance of wires and cables with a fixed structure includes a test component 1. The test component 1 consists of a support base 101 and an electric heating wire heater 102. Two sets of clamping mechanisms 2 are provided on the top of the support base 101. Wires and cables 4 are clamped between the two sets of clamping mechanisms 2. A control unit 3 for driving the clamping mechanisms 2 is provided on the top of the support base 101. Furthermore, the control unit 3 includes a control slider 31, which is slidably mounted on the top of the support base 101. A support rod 32 is hinged to the side of the control slider 31. The end of the support rod 32 away from the control slider 31 is connected to the clamping mechanism 2. A contact spring 33 is fixed to the side of the control slider 31 near the heating wire heater 102. The end of the contact spring 33 away from the control slider 31 is fixed to the support base 101. An L-shaped support rod 34 is fixed to the top of the support base 101. A locking rod 35 is provided on the L-shaped support rod 34. 5 passes through and slides with the L-shaped support rod 34. A return spring 36 is fixed at the top of the L-shaped support rod 34. The end of the return spring 36 away from the L-shaped support rod 34 is fixed to the clamping rod 35. A slot 37 is opened at the top of the control slider 31. The clamping rod 35 can be inserted into the slot 37 to limit the control slider 31. This allows the operator to operate the control slider 31 without having to hold it all the time. They only need to pass the wire cable 4 through the clamping mechanism 2. It can be operated by a single person, which is convenient and effectively improves the overall work efficiency.

[0016] In an embodiment of this utility model, the clamping mechanism 2 includes a clamping base plate 21, which is slidably mounted on the top of the support base 101. A fixing rod 22 is fixed to the top of the clamping base plate 21. The fixing rod 22 passes through the clamping top plate 23 and is slidably connected to the clamping top plate 23. A connecting spring 24 is fixed to the top of the clamping top plate 23. One end of the connecting spring 24 away from the clamping top plate 23 is fixed to the fixing rod 22. Clamping holes are provided at the bottom of the clamping top plate 23 and the top of the clamping base plate 21. A rubber pad 25 is fixed to the inside of the clamping hole. The downward force of the connecting spring 24 on the clamping top plate 23 allows the clamping top plate 23 to keep in contact with the clamping base plate 21 to clamp the wire and cable 4. During clamping, the rubber pad 25 is squeezed to further improve the fixing effect.

[0017] Furthermore, one end of the support rod 32 connected to the clamping mechanism 2 is hinged to the side of the clamping base plate 21 near the control slider 31. By pulling the control slider 31, the control slider 31 can pull the clamping base plate 21 and the clamping top plate 23 to move closer to or further away from the center of the support base 101 via the support rod 32, thereby achieving the goal of tightening and straightening the wire and cable 4.

[0018] In this utility model, the electric heating wire heater 102 is embedded in the top of the support base 101. The top of the support base 101 is provided with a horizontal sliding groove 5 for two sets of clamping base plates 21 to slide left and right, and a vertical sliding groove 6 for controlling the slider 31 to move back and forth.

[0019] Furthermore, a support member 7 is provided at the bottom of the clamping top plate 23, the top of the clamping bottom plate 21, and the front of the support base 101. The support member 7 includes an abutment hole 71, which is formed at the bottom of the clamping top plate 23 and the top of the clamping bottom plate 21. A bracket 72 is fixed to the front of the support base 101. Two sets of brackets 72 are provided, and the two sets of brackets 72 are symmetrically arranged on the front of the support base 101. A crossbar 73 is fixed between the two sets of brackets 72, and the crossbar 73 passes through. Two sets of protrusions 74 and a crossbar 73 are fixedly connected to the protrusions 74. When the clamping top plate 23 and the clamping bottom plate 21 move to the position of the protrusions 74 near the center of the support base 101, the protrusions 74 can be inserted into the contact holes 71 between the clamping top plate 23 and the clamping bottom plate 21, thereby opening up the clamping top plate 23 and the clamping bottom plate 21 and loosening the fixation of the wire and cable 4. The staff can then remove the wire and cable 4 after the inspection is completed and place a new wire and cable 4.

[0020] Furthermore, the bottom of the lever 35 is inclined on the side near the control slider 31. When the control slider 31 moves towards the side near the lever 35 and touches the lever 35, the control slider 31 pushes the lever 35 upward by touching the inclined surface at the bottom of the lever 35. When the slot 37 at the top of the control slider 31 moves to the position of the lever 35, the lever 35 can move downward and insert into the slot 37 under the action of the return spring 36, thus limiting the control slider 31.

[0021] The operator manually pushes the control slider 31, causing it to move away from the electric heating wire heater 102. The control slider 31 pulls the clamping base plate 21 and clamping top plate 23 towards the center of the support base 101 via the support rod 32. When the clamping base plate 21 and clamping top plate 23 move to the position of the protrusion 74, the protrusion 74 can be inserted into the abutment hole 71 between the clamping top plate 23 and clamping base plate 21, thereby opening the clamping top plate 23 and clamping base plate 21.

[0022] At this point, the control slider 31 moves to the position of the locking rod 35. The locking rod 35 inserts into the slot 37 to limit the control slider 31. The operator only needs to insert the wire cable 4 through the clamping hole between the clamping top plate 23 and the clamping bottom plate 21. After placement, simply pull the locking rod 35 upwards to disengage it from the slot 37 at the top of the control slider 31, releasing the limitation on the control slider 31. At this time, the control slider 31 can move towards the side closer to the heating wire heater 102 under the action of the resisting spring 33. 31. The clamping base plate 21 and clamping top plate 23 are pushed by the support rod 32 to move away from the center of the support base 101. When the clamping base plate 21 and clamping top plate 23 are no longer abutted by the protrusion 74, the clamping top plate 23 moves downward under the action of the connecting spring 24 to cooperate with the clamping base plate 21 and the rubber pad 25 to clamp the wire and cable 4. As the clamping base plate 21 and clamping top plate 23 move, the wire and cable 4 is straightened. At this time, the heat resistance performance of the wire and cable 4 can be tested by simply activating the electric heating wire heater 102.
