Description

Technical Field

[0001] This invention relates to the field of fire resistance testing technology, specifically to a fire resistance testing device for the production of fire-resistant wires and cables. Background Technology

[0002] Wires and cables are wire products used to transmit electrical energy, information, and realize electromagnetic energy conversion. Wires and cables consist of one or more insulated wire cores, as well as their respective possible covering layers, overall protective layer, and outer sheath. There are many types of existing wires and cables, and fire-resistant wires and cables are one of them. Existing fire-resistant wires and cables need to undergo fire resistance tests after production to test the safety of the wires and cables in use.

[0003] When conducting fire resistance tests on fire-resistant wires and cables, workers often hold the equipment by hand. However, prolonged hand support can cause the equipment to wobble, hindering observation. Most fire resistance testers have fixed supports, preventing directional adjustments once the wires and cables are in place. Testing at different locations requires disassembling and readjusting, which is inconvenient. The use of the rotating block and second support leg, with one end of the ring being heavy, can easily lead to imbalance. Furthermore, the wires and cables need to be secured during testing; directly suspending them at the crossbar 13 could cause them to detach. Summary of the Invention

[0004] The purpose of this invention is to provide a fire resistance testing device for the production of fire-resistant wires and cables, so as to solve the problems of poor flexibility, inability to rinse and disinfect the device, and poor stability mentioned in the background art.

The connecting pipe 7 communicates with the gas plate 8. The gas head 9 is the gas outlet.

[0026] A first support leg 11 is fixedly connected to one side of the top of the storage box 1. An arc groove 12 is fixedly connected to the top of the first support leg 11. A crossbar 13 is placed inside the arc groove 12. A ring 14 is fixedly connected to one side of the crossbar 13. A handle 15 is fixedly connected to one side of the ring 14. A limit block 16 is fixedly connected to the periphery of one end of the crossbar 13. A threaded groove 17 is fixedly connected to the top of the limit block 16. A threaded rod 18 is embedded inside the threaded groove 17. A rotating block 19 is fixedly connected to the bottom of the limit block 16. A second support leg 20 is embedded at the bottom of the rotating block 19. A hinge 21 is fixedly connected to one side of the outer wall of the second support leg 20. The crossbar 13 is supported inside the arc groove 12 and the limit block 16. The crossbar 13, the ring 14, and the handle 15 are an integral structure. The threaded groove 17 and the threaded rod 18 cooperate with each other and are threadedly engaged.

[0027] A rubber clamp head 22 is fixedly connected to the bottom surface of the rotating block 19, and a limiting groove 23 is fixedly connected to the top surface of the second support leg 20. A clamping block 24 is fixedly connected to the periphery of the crossbar 13. A fastening bolt 25 is embedded inside the clamping block 24. The rubber clamp head 22 and the limiting groove 23 cooperate with each other, and two of each are provided. The clamping block 24 is used to clamp and place wires and cables. The inside of the clamping block 24 has an arc groove structure, and the fastening bolt 25 is installed through the clamping block 24.

[0028] Preferably, the combustion device is composed of a gas interface 4, a valve 5, a gas pipe 6, a connecting pipe 7, a gas plate 8, a gas head 9, and a support block 10. When conducting fire resistance tests on fire-resistant wires and cables, workers often hold the equipment by hand, which can cause it to wobble and hinder observation. By setting up the combustion device, the support block 10 supports the device. When in use, the valve 5 is rotated to start the operation. The two ends of the gas pipe 6 are connected to the gas interface 4 and the connecting pipe 7, respectively. The connecting pipe 7 is connected to the gas plate 8. The gas head 9 is the gas outlet. Ignition causes the gas head 9 to burn the gas, forming a flame to conduct fire resistance tests on the wires and cables. The gas cylinder 3 is placed inside the storage box 1 to supply gas.

[0029] Preferably, the adjustment device is composed of a first support leg 11, an arc groove 12, a crossbar 13, a ring 14, a handle 15, a limiting block 16, a threaded groove 17, a threaded rod 18, a rotating block 19, a second support leg 20, and a hinge 21. For most fire resistance testers, most supports are fixed. After fixing the wires and cables, the orientation cannot be adjusted. When testing in different locations, it is necessary to remove and readjust the position, which is inconvenient. By setting up an adjustment device, the crossbar 13 is supported inside the arc groove 12 and the limiting block 16. The ring 14 and handle 15 are integrated. When the orientation needs to be adjusted, the handle 15 can be gripped and rotated to rotate the angle of the crossbar 13 to adjust the angle of different orientations. The threaded groove 17 and the threaded rod 18 cooperate with each other and are threadedly engaged. When the angle rotation is not needed, the threaded rod 18 is rotated downward to press the crossbar 13 and prevent it from moving on its own. The rotating block 19 is connected to the second support leg 20 by a hinge 21, which allows the crossbar 13 to be easily raised during disassembly, making it easy to disassemble and clean the combustion device.

[0030] Preferably, the clamping device is composed of a rubber clamp head 22, a limiting groove 23, a clamping block 24, and a fastening bolt 25. The use of the rotating block and the second support leg, with one end of the ring being heavier, can easily lead to imbalance. During the testing of wires and cables, fixation is required, and directly suspending them on the crossbar can easily cause them to fall off. By setting up the clamping device, the rubber clamp head 22 and the limiting groove 23 cooperate with each other, with two of each type. This increases the friction and fixation between the rotating block and the second support leg, preventing imbalance. The clamping block 24 is used to clamp and place the wires and cables. The interior of the clamping block 24 has an arc-shaped groove structure for placing the wires and cables. The fastening bolt 25 is installed through the clamping block 24 to strengthen the fixation between the wires and cables and prevent positional movement within the clamping block 24.

[0031] Working principle: The support block 10 supports the combustion device. During use, the start valve 5 is rotated. The two ends of the gas pipe 6 are connected to the gas interface 4 and the connecting pipe 7, respectively. The connecting pipe 7 is connected to the gas plate 8. The gas head 9 is the gas outlet. Ignition causes the gas head 9 to burn the gas, forming a flame for fire resistance testing of wires and cables. The gas cylinder 3 is placed inside the storage box 1 to supply gas. The crossbar 13 is supported inside the arc groove 12 and the limiting block 16. The crossbar 13, ring 14, and handle 15 are an integrated structure. When adjustment of the orientation is needed, the handle 15 can be gripped and rotated to rotate the crossbar 13 to adjust the angle of different orientations. The threaded groove 17 and threaded rod 18 cooperate with each other, with threaded engagement. When no angle rotation is needed, the threaded rod 18 is rotated downwards. The crossbar 13 is squeezed to prevent it from moving on its own. The rotating block 19 and the second support leg 20 are connected by a hinge 21, which allows the crossbar 13 to be easily erected during disassembly, facilitating disassembly and cleaning of the combustion device. The rubber clamp 22 and the limiting groove 23 cooperate with each other, with two of each, to increase the friction and fixation between the rotating block and the second support leg during the cooperation, preventing imbalance on both sides. The clamping block 24 is used to clamp and place wires and cables. The clamping block 24 has an arc groove structure inside for placing wires and cables. The fastening bolt 25 is installed through the clamping block 24 to strengthen the fixation between wires and cables and prevent the clamping block 24 from moving. The contents not described in detail in this description are prior art known to those skilled in the art.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
