Description

Technical Field

[0001] The utility model relates to the technical field of navigation light upper cover testing, in particular to a navigation light upper cover shear force testing tool. Background Art

[0002] Navigation light covers are typically made of transparent or translucent materials, such as plastic or glass. They protect the bulb or LED light source while ensuring that light can be effectively transmitted and seen, providing navigation and identification functions. However, since navigation light covers are used in airports, which are subject to extreme environments, new navigation light covers must be subjected to shear force testing during installation and replacement.

[0003] Currently, most tests are performed using dedicated testing equipment, which is not only cumbersome to operate but also inconvenient to carry. Airports have large areas, and using testing equipment for testing not only requires vehicles for transportation but also consumes energy, which is not conducive to the use of airports. Therefore, we have introduced a shear force test tool for navigation light covers. Utility Model Content

[0004] The main purpose of the utility model is to provide a shear force testing tool for the upper cover of a navigation light, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A shear force testing tool for the upper cover of a navigation light comprises a vertical plate, wherein the left and right ends of the vertical plate are fixedly connected to side support plates, and the two side support plates are both narrow at the top and wide at the bottom. The lower end of the vertical plate and the lower ends of the two side support plates are commonly fixedly connected to a base, and the middle part of the front end of the vertical plate is movably connected to the upper cover body, and the four corners of the front end of the vertical plate are fixedly connected to No. 1 threaded rods, and the outer surfaces of the four No. 1 threaded rods are threadedly connected to No. 1 nuts, and the four No. 1 threaded rods are commonly movably connected to a pressure plate, and the middle part of the front end of the pressure plate is threadedly connected to a testing mechanism, and the position of the testing mechanism corresponds to the position of the upper cover body.

[0007] Preferably, the testing mechanism includes a testing block, the front end of which is movably connected to a No. 3 threaded rod via a bearing, the front end of which is fixedly connected to a column, the outer surface of which is fixedly connected to three shift rods, and the three shift rods are equidistantly distributed.

[0008] Preferably, four corners of the front end of the pressure plate are provided with through holes that pass through the front and back, and a threaded hole is provided in the middle of the front end of the pressure plate.

[0009] Preferably, the No. 3 threaded rod is threadedly connected to the threaded hole, and the test pressure block is located at the rear of the pressure plate.

[0010] Preferably, two No. 2 threaded rods are fixedly connected to the four corners of the rear end of the vertical plate, the four groups of No. 2 threaded rods are all inserted with movably connected limit plates, and the eight No. 2 threaded rods are all threadedly connected with No. 2 nuts.

[0011] By adopting the above technical solution, the limiting plate can be disassembled and its position can be adjusted to accommodate upper covers of different lengths.

[0012] Preferably, the four limiting plates are all located at the rear of the upper cover body.

[0013] Preferably, the four limiting plates are all in contact with the rear end of the upper cover body.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The upper cover body is connected with the vertical plate through insertion. At this time, the four limit plates at the rear end of the vertical plate will limit the upper cover body to prevent the upper cover body and the vertical plate from falling off. Then the pressure plate is movably connected with the four No. 1 threaded rods through insertion. The pressure plate is limited by rotating the No. 1 nut on the No. 1 threaded rod, so that the test mechanism on the pressure plate is close to the upper cover body. At this time, the three levers are rotated to drive the column and the No. 3 threaded rod to rotate. Since the No. 3 threaded rod is threadedly connected to the pressure plate, the No. 3 threaded rod will cause the test pressure block to move backward when it rotates. The test pressure block squeezes the upper cover body, thereby simulating the actual on-site environment and testing the shear force. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] See also Figure 1-4 , the utility model provides a technical solution:

[0025] A shear force testing tool for the upper cover of a navigation light comprises a vertical plate 1, wherein the left and right ends of the vertical plate 1 are fixedly connected to side support plates 3, and the two side support plates 3 are both narrow at the top and wide at the bottom. The lower end of the vertical plate 1 and the lower ends of the two side support plates 3 are commonly fixedly connected to a base 8, and the middle part of the front end of the vertical plate 1 is movably connected to the upper cover body 2, and the four corners of the front end of the vertical plate 1 are fixedly connected to No. 1 threaded rods 4, and the outer surfaces of the four No. 1 threaded rods 4 are threadedly connected to No. 1 nuts 6, and the four No. 1 threaded rods 4 are commonly movably connected to a pressure plate 5, and the middle part of the front end of the pressure plate 5 is threadedly connected to a testing mechanism 7, and the position of the testing mechanism 7 corresponds to the position of the upper cover body 2.

[0026] In this embodiment, the testing mechanism 7 includes a testing pressure block 71, the front end of which is movably connected to a No. 3 threaded rod 72 through a bearing, the front end of the No. 3 threaded rod 72 is fixedly connected to a column 73, and the outer surface of the column 73 is fixedly connected to three shift rods 74, and the three shift rods 74 are equidistantly distributed; the four corners of the front end of the pressure plate 5 are provided with through holes 51 that pass through the front and back, and a threaded hole 52 is provided in the middle of the front end of the pressure plate 5; the No. 3 threaded rod 72 is threadedly connected to the threaded hole 52, and the testing pressure block 71 is located at the rear of the pressure plate 5.

[0027] Through the above solution: rotating the three levers 74 rotates the column 73 and the third threaded rod 72, and the rotation of the third threaded rod 72 causes the test pressing block 71 to move backward and contact the upper cover body 2, squeezing it, thereby improving the test efficiency.

[0028] In this embodiment, two No. 2 threaded rods 12 are fixedly connected to the four corners of the rear end of the vertical plate 1, and the four groups of No. 2 threaded rods 12 are all movably connected with the limiting plates 13, and the eight No. 2 threaded rods 12 are all threadedly connected with No. 2 nuts 11; the four limiting plates 13 are all located at the rear part of the upper cover body 2; the four limiting plates 13 are all in contact with the rear end of the upper cover body 2.

[0029] Through the above solution, by adjusting the position of the No. 2 nut 11 , the position of the limiting plate 13 on the No. 2 threaded rod 12 can be adjusted, thereby adapting to different upper cover bodies 2 for testing.

[0030] It should be noted that the present invention is a shear force testing fixture for the navigation light upper cover. During use, the upper cover body 2 is first connected to the vertical plate 1 through an interlaced connection. At this time, the four limit plates 13 at the rear end of the vertical plate 1 will play a key role in ensuring that the upper cover body 2 is stably connected to the vertical plate 1 to prevent it from falling off. Subsequently, the pressure plate 5 is interlaced and movably connected to the four No. 1 threaded rods 4, and the pressure plate 5 is precisely limited and adjusted by rotating the No. 1 nut 6 on the No. 1 threaded rod 4. When the test mechanism 7 on the pressure plate 5 is close to the upper cover body 2, the cylinder 73 and the No. 3 threaded rod 72 are driven to rotate synchronously by rotating the three levers 74. Since the No. 3 threaded rod 72 is threadedly connected to the pressure plate 5, the rotation of the No. 3 threaded rod 72 will push the test pressure block 71 to move backward, thereby applying pressure to the upper cover body 2, simulating the actual on-site environment, and realizing accurate testing of the shear force.
