The support plate 37 and the side end of the body 1 are provided with multiple sliding grooves 38. Each arc-shaped support plate 37 is fixedly connected to the side end of a first column rod 310. Each first column rod 310 is provided with a spring 39. One end of each spring 39 is fixedly connected to the side end of the arc-shaped support plate 37, and the other end of each spring 39 is fixedly connected to the side end of the body 1. Two holes 8 are provided on the side end of the body 1. An observation window 2 is provided on the side end of the body 1. A DC motor 5 is provided on the side end of the body 1. A threaded rod 9 is fixedly connected to the output shaft of the DC motor 5. A support block 6 is provided on the side end of the threaded rod 9. An igniter 7 is provided on the side end of the support block 6.
[0017] The overall effect of Embodiment 1 is as follows: the relevant components can improve the traditional fire-resistant testing device for outdoor lighting wiring harnesses by mechanical transmission to adapt to fixing wiring harnesses of different specifications. The function of the support plate 31 is to support the sliding of the first slider 32. The first arc plate 35 and the second arc plate 36 facilitate the fixing of wiring harnesses of different diameters. The threaded rod 9 is obliquely set at the side end of the body 1 to facilitate different spacing between the igniter 7 and the wiring harness. This mechanical transmission method is beneficial for developing new wiring harnesses or conducting multi-category comparative tests.
[0018] Example 2, as Figures 1-6 As shown, the shielding mechanism 4 includes two shielding frame plates 41. A second column 43 is fixedly connected to the side end of each shielding frame plate 41. A spiral spring 46 is provided on the side end of each second column 43. An arc-shaped block 44 is fixedly connected to the side end of each second column 43. Multiple blocks 42 are provided on the side end of the body 1. Every two blocks 42 are located on the two sides of the second column 43. An arc-shaped groove 45 is opened inside the block 42. The side end of each arc-shaped block 44 is slidably connected to the inside of the arc-shaped groove 45. The arc-shaped groove 45 is opened on the block 42 near the spiral spring 46. One end of each spiral spring 46 is fixedly connected to the side end of the block 42, and the other end of each spiral spring 46 is fixedly connected to the side end of the shielding frame plate 41.
[0019] The effect achieved by the entire embodiment 2 is as follows: by setting the blocking mechanism 4, the blocking frame plate 41 drives the second column rod 43 to rotate, the arc block 44 slides inside the arc groove 45, and the spiral spring 46 deforms, which not only facilitates the blocking of the body 1 by the blocking frame plate 41, but also provides restoring force to realize the convenient closing of the blocking frame plate 41.
[0020] The working principle of the entire equipment is as follows: Installation and inspection phase: Before starting the test, ensure that all parts of the structure are in a stable state to prevent any part of the structure from malfunctioning after the work is completed.
[0021] Opening the shielding frame: The operator rotates the shielding frame 41 around the center of the second column 43. At the same time, the shielding frame 41 drives the second column 43 to rotate at the side end of the block 42. The arc block 44 slides inside the arc groove 45, the spiral spring 46 deforms, and the shielding frame 41 opens accordingly.
[0022] During the wire harness fixing stage: First, slide the first slider 32 to the side close to the arc-shaped support plate 37. Then, slide the second arc-shaped plate 36 and the arc-shaped support plate 37 on the side of the body 1, exposing the slot 8. At this time, the arc-shaped support plate 37 slides inside the slide groove 38. The arc-shaped support plate 37 drives the first column rod 310 to slide on the side of the body 1, and the spring 39 deforms, passing the wire harness through the slot 8. Release the second arc-shaped plate 36. At this time, the side of the second arc-shaped plate 36 is in contact with the wire harness. Then rotate the bidirectional threaded rod 33. The threaded rod 33 drives the second slider 34 to slide on the side of the first slider 32. At the same time, the second slider 34 drives the first arc plate 35 to fix the wire harness. According to the length of the wire harness, the first slider 32 slides on the side of the support plate 31. After sliding to the appropriate position, the operator closes the shielding frame 41 in the reverse direction as if opening the shielding frame 41, starts the DC motor 5, drives the threaded rod 9 to rotate, the support block 6 slides outside the threaded rod 9, and the igniter 7 burns the wire harness.
