Description

Technical Field

[0001] This utility model relates to the field of spark detection technology, specifically a protective mechanism and its spark detection machine. Background Technology

[0002] A spark tester is an electrical performance testing device, mainly used to detect whether electrical equipment such as wires and cables have problems such as copper leakage, insulation damage, and withstand voltage issues.

[0003] The wires and cables enter the spark tester from one side. Electric sparks are generated between the electrodes inside the machine. If the insulation performance of the wires and cables does not meet the requirements, the electric sparks will break down the test sample, resulting in leakage.

[0004] During the testing process, the wires and cables enter the machine through the feed port on one side. During this process, the outer wall of the wires and cables can easily scrape against the edge of the inner wall of the feed port of the spark tester, which may damage the insulation sleeve on the wires and cables, thereby reducing the protective effect of the spark tester on the wires and cables. To address this, we propose a protective mechanism and a spark tester thereof. Utility Model Content

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely.

[0026] This application provides a protective mechanism and its spark detection machine, which solves the problem that wires and cables are easily scratched before entering the detection area. The wires and cables pass between the two horizontal axes 203 and the vertical axis 202 in sequence before entering the feed inlet. The two horizontal axes 203 and the vertical axis 202 prevent the wires and cables from contacting the four edges of the feed inlet. At the same time, the L-shaped design of the L-shaped plate 201 ensures that the L-shaped plate 201 will not obstruct the wires and cables, thereby improving the protection effect of the wires and cables.

[0027] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0028] This utility model discloses a protective mechanism.

[0029] According to the appendix Figure 1 As shown in Figure 4, the device includes a housing 101, a protective mechanism, and an observation mechanism. A top cover 102 is hinged to the top of the housing 101. A feed inlet is provided on one side of the housing 101. The protective mechanism is located at the feed inlet and protects the wires and cables at the feed inlet.

[0030] In a preferred embodiment, a protective mechanism is disposed on one side of the housing 101. The protective mechanism includes an L-shaped plate 201, which is symmetrically disposed on one side of the housing 101. A horizontal shaft 203 is rotatably connected to the top of each L-shaped plate 201. A vertical shaft 202 is rotatably disposed between the two L-shaped plates 201. An adjustment mechanism is disposed between the vertical shaft 202 and the L-shaped plate 201. The wires and cables pass between the two horizontal shafts 203 and the vertical shaft 202 in sequence before entering the feed inlet. The two horizontal shafts 203 and the vertical shaft 202 prevent the wires and cables from contacting the four edges of the feed inlet. At the same time, the L-shaped design of the L-shaped plate 201 ensures that the L-shaped plate 201 will not obstruct the wires and cables. Furthermore, the rotatable design of the vertical shaft 202 and the horizontal shaft 203 makes the contact between the wires and cables during movement smoother, thereby improving the protective effect on the wires and cables.

[0031] The adjustment mechanism includes a slide groove 301, which is located on the front of the L-shaped plate 201. Threaded rods 302 are interposed inside the two slide grooves 301. The longitudinal shaft 202 is rotatably sleeved on the outer wall of the threaded rod 302. A locking nut 303 is threaded onto the outer wall of the threaded rod 302. A fixing mechanism is provided between the L-shaped plate 201 and the housing 101. The threaded rod 302 moves within the slide groove 301, and the locking nut 303 is tightened on the outer wall of the threaded rod 302, causing the locking nut 303 to abut against the outer wall of the L-shaped plate 201. This fixes the threaded rod 302, thereby adjusting the position of the longitudinal shaft 202 and improving its applicability.

[0032] The fixing mechanism includes a fixing plate 401, which is fixedly connected to the side of the L-shaped plate 201. A hole 402 is provided on one side of the fixing plate 401, and a fixing bolt 403 is inserted through the inner wall of the hole 402. The fixing bolt 403 is threadedly connected to one side of the housing 101. By passing the fixing bolt 403 through the hole 402 and screwing it into the housing 101, the fixing plate 401 and the housing 101 can be fixed, thereby fixing the L-shaped plate 201 and the housing 101, thus improving the stability of the protective mechanism.

[0033] The observation mechanism is located at the top of the top cover 102. The observation mechanism includes an observation glass 501, which is inserted into the top of the top cover 102. The top cover 102 is equipped with a cleaning mechanism. The inspection situation below the top cover 102 can be observed through the observation glass 501.

[0034] The cleaning mechanism includes a brush 602. A movable plate 601 is slidably disposed inside the top cover 102. The brush 602 is distributed all over the surface of the movable plate 601. A sliding mechanism is provided between the movable plate 601 and the inner wall of the top cover 102. By moving the movable plate 601, the brush 602 contacts the bottom end of the observation glass 501, thereby cleaning the surface of the observation glass 501 inside the top cover 102 and avoiding obstruction of the surface of the observation glass 501 during the testing process.

[0035] The sliding mechanism includes a sliding strip 701, a U-shaped block 702 fixedly connected to the inner wall of the top cover 102, a sliding connection between the outer wall of the sliding strip 701 and the inner wall of the U-shaped block 702, a movable plate 601 fixedly connected between the two sliding strips 701, and an operating mechanism provided on the outside of the top cover 102. The operating mechanism includes a connecting groove 801, which is symmetrically opened at the top of the top cover 102. A connecting block 802 is slidably connected to the inner wall of the connecting groove 801, the bottom end of the connecting block 802 is fixedly connected to the top end of the sliding strip 701, and a movable strip 801 is fixedly connected between the two connecting blocks 802. 03. Moving the movable bar 803 will drive the two connecting blocks 802 to move, thereby driving the sliding bar 701 to move, which in turn drives the movable plate 601 to move. At the same time, the U-shaped block 702 limits the sliding bar 701, making the movement of the movable plate 601 more stable and ensuring that the bristles 602 can stably contact the surface of the observation glass 501. In addition, the sliding bar 701 has a certain length, so that no matter how the movable bar 803 moves, it can block the connecting groove 801, preventing the connecting groove 801 from connecting the inside of the top cover 102 with the outside.

[0036] This utility model also provides a spark detection machine, including the protective mechanism of any one of the above.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
