Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] like Figure 1-5As shown, an auxiliary device for verifying the reliability of the launch tube top cover opening and closing mechanism includes a base frame 1, a support 2, and a rotating mechanism 3. The support 2 is located at the upper end of the base frame 1, and a flexible support member 4 is located at the top of the support 2. The flexible support member 4 includes mesh straps 41 arranged in a grid pattern for flexibly supporting the top cover 6, preventing bumps and impacts during support, and providing protection when supporting the top cover 6. The support 2 is rotatably connected to the base frame 1 via the rotating mechanism 3, allowing the top cover 6 located on the flexible support member 4 to alternate between an open and closed state. This invention can effectively support the launch tube top cover in the open state, providing protection, and can quickly and reliably drive the launch tube top cover to the closed state, assisting in reliability cycle testing, thereby ensuring the safety of the test sample (top cover) and improving test efficiency.

[0028] like Figure 1-3 As shown, the top of the bracket 2 is provided with a U-shaped frame 21 that is inclined to the main body of the bracket 2. The two ends of the mesh strap 41 are fixed to the two sides of the U-shaped frame 21, and the mesh strap 41 is in a loose state, which is adapted to the outer diameter of the top cover 6. By adjusting the length of the mesh strap 41, the loose state of the mesh strap 41 is adapted to the outer diameter of the top cover, so that the mesh strap 41 can wrap around the opened top cover when receiving it, providing the best protection effect and avoiding damage to the top cover. In addition, the main body of the bracket 2 is also a U-shaped frame, with the same opening direction as the U-shaped frame 21, both facing the launch tube top cover opening and closing mechanism (not shown in the figure), which facilitates the receiving of the top cover 6.

[0029] like Figure 3 As shown, the two ends of the mesh strap 41 are connected to the U-shaped frame 21 by fasteners. The fasteners include a fixing plate 42 and a pressing plate 43. The fixing plate 42 is fixed to the outer side of the side of the U-shaped frame 21. Multiple pressing plates 43 are provided to press one end of each strap arranged horizontally on the mesh strap 41 onto the fixing plate 42.

[0030] like Figure 1 , 3 As shown, the flexible support member 4 also includes a sponge 44 covering the outside of the U-shaped frame 21, and the inner side of the sponge 44 covering the two sides of the U-shaped frame 21 is provided with a wire groove for the mesh strap 4 to pass through, and the wire groove is narrow.

[0031] like Figure 1-5As shown, the rotating mechanism 3 includes a rotating shaft 31, a bearing seat 32, and a drive assembly. One side of the bottom of the bracket 2 is a hinge end, and a rotating shaft 31 is provided on each side of this hinge end. The top of the base frame 1 is provided with bearing seats 32 symmetrically located at both ends of each rotating shaft 31. The two ends of the rotating shaft 31 are inserted into the bearing seats 32 and rotatably connected to the bearing seats 32. The other side of the bottom of the bracket 2 is a rotating movable end, and the drive assembly is located at the rotating movable end for driving the rotating movable end of the bracket 2 to rotate around the hinge end.

[0032] like Figure 1 , 2 As shown in Figure 4, the drive assembly includes a ball-end screw 33, a handwheel 34, a rotating shaft nut 35, and a connector 36. The rotating shaft nut 35 has symmetrically arranged bushings 37 at both ends, which are installed on one side of the base frame 1. The ball-end screw 33 is threadedly connected to the rotating shaft nut 35. One end of the ball-end screw 33 has a handwheel 34, and the other end has a cap 38. The cap 38 is connected to the connector 36, which is hinged to a hinge seat 39 located in the middle of the rotating movable end of the support 2. Rotating the handwheel 34 drives the ball-end screw 33 to move axially, thereby driving the rotating movable end of the support 2 to rotate around the hinge end. This invention has a small rotational stroke; manual adjustment not only saves costs but also provides a gentle adjustment, avoiding serious consequences (damage to the launch tube top cover) caused by the failure of the automatic drive device.

[0033] Example 2

[0034] Based on the structure of Example 1, such as Figure 1 , 2 As shown in Figure 5, two symmetrically arranged limiting support members 5 are also provided on both sides of the upper end of the base frame 1. The limiting support members 5 are used to support the rotating movable end of the bracket 2 and limit the rotation angle of the bracket 2 when the top cover 6 is in the open state. Specifically, the limiting support member 5 includes a support base 51 and an adjusting plate 52. The adjusting plate 52 is fixed to the side of the base frame 1 and has an elongated hole. The side of the support base 51 is connected to the adjusting plate 52 by fasteners passing through the elongated hole, and its top is used to support the bracket 2. The setting of the limiting support member 5 not only reduces the load on the drive component, but also indicates whether the manual adjustment position is in place, thus improving the test efficiency.

[0035] like Figure 1 , 2 As shown, the four corners of the bottom of the base frame 1 are also provided with adjustable feet 11, which can adjust the height of the base frame to match the height of the test device.

[0036] The working principle of this utility model is as follows: Before the test, the auxiliary device is placed below the top cover of the launch tube and adjusted to a suitable height. Then, the length of the mesh strap 41 is adjusted according to the outer diameter of the top cover 6 so that it can wrap around the opened top cover. The initial angle of the bracket 2 is preset according to the opening angle of the top cover 6, and the installation height of the support base 51 is adjusted. After adjustment, the test begins. The launch tube top cover opening and closing mechanism is opened, and the top cover 6 is opened and falls onto the mesh strap 41. Then, the handwheel 34 is turned to rotate the bracket 2 toward the launch tube top cover opening and closing mechanism, driving the top cover 6 back to the closed state. The launch tube top cover opening and closing mechanism is then closed, and the handwheel 34 is turned to rotate the bracket 2 back to the initial angle. The launch tube top cover opening and closing mechanism is opened again, and this continuous opening and closing operation is performed. After reaching the specified number of cycles, the function of the launch tube top cover opening and closing mechanism is checked to see if it is normal, if there is any permanent deformation, and whether the parameters such as opening and closing time and force value are within the allowable tolerance range. The test is then judged to be qualified. The auxiliary device of this invention facilitates the reliability test of the launch tube top cover opening and closing mechanism and improves the test efficiency.
