Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, and specifically relates to a fixing device for detecting damage of a tensioned film. Background Technique

[0002] In the fields of civil engineering, aerospace, etc., film materials are widely used due to their excellent lightweight and multifunctional characteristics, and the tensile force performance of the film is particularly crucial. Spacecraft need to withstand extreme temperature changes, radiation, and mechanical stress in the space environment, and the film materials must have sufficient tensile force to ensure the integrity of the structure and the stability of the function. The research on the tensile force of the film not only ensures the safety and reliability of the spacecraft but also promotes the development of aerospace technology.

[0003] Therefore, in order to prevent the film from shaking during the detection process, a fixing device is needed to tighten the film. In the past, such devices often used hook bodies to support the film, but the hooking positions and lengths were fixed and could not be adjusted according to films of different widths and lengths.

[0004] Now, a new fixing device for detecting damage of a tensioned film is proposed to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a fixing device for detecting damage of a tensioned film to solve the problem of inconvenient film fixing proposed in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A fixing device for detecting damage of a tensioned film, including a frame and a push plate. Four sides inside the frame are respectively provided with push plates, and two screw rods are respectively fixed on the outer sides of the push plates. A connecting rod is fixed between the outer parts of the screw rods. Two groups of through grooves are respectively arranged inside the four sides of the frame, and a secondary gear disk is movably connected to the outer side of the through groove. A main gear disk is meshed and connected at the center between the secondary gear disks. Three groups of suspension rods are fixed on the surface of the push plate, and a first hook is hinged at the end of the suspension rod. Sleeve tubes are respectively fixed at the four corners inside the frame, and inserting rods are movably inserted into the sleeve tubes. A limiting block is fixed around the outer wall of the inserting rod, and a spring is welded between the limiting block and the sleeve tube. A second hook is hinged at the end of the inserting rod. A film is arranged at the center inside the frame. Bases are respectively welded on both sides of the bottom of the frame.

[0007] Further, the screw rod is embedded in the secondary gear disk, and the thread on the outer wall of the screw rod matches the thread on the inner wall of the secondary gear disk.

[0008] Further, the main gear disk is movably assembled on the outer wall of the frame, and the main gear disk and the two side secondary gear disks are on the same horizontal plane.

[0009] Furthermore, the insertion rod can slide back and forth along the inner wall of the sleeve, inside the spring in front of the insertion rod.

[0010] Furthermore, three groups of hole one are respectively arranged inside the four sides of the film, and hole two are respectively arranged at the four corners inside the film. A clamping ring is respectively inserted and fixed in the hole one and the hole two, and a sleeve is fixedly sleeved behind the clamping ring.

[0011] Furthermore, the sleeve ring can slide back and forth along the outer wall of the snap ring, and the sleeve ring and the snap ring are arranged in concentric circles.

[0012] Furthermore, the second holes are symmetrically distributed at four corners in the film, and the second holes are arranged at the angle of the first hole.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the fixing device for detecting damage to the tensioned film not only realizes the rapid tightening of the film, but also achieves the purpose of avoiding tearing of the film;

[0014] (1) A hook 1 is hinged at the end of the suspension rod, and a hook 2 is hinged at the end of the insertion rod. According to the specifications of the film to be fixed in the frame, the main gear plate is first turned around, and the auxiliary gear plates on both sides are pushed and turned by the main gear plate. Under the restriction of the connecting rod, the screw rod and the push plate connected to it are lifted and lowered along the through groove, so as to adjust the spacing between the suspension rods and the hook 1 around the periphery, and the hook 1 is hung in the hole 1 of the film. The insertion rods embedded in the sleeves at the four corners are restricted by springs, which can squeeze the springs and extend the insertion rods until the hinged hook 2 is hooked in the hole 2, so that the film can be tightened from multiple directions and angles without damaging the film.

[0015] (2) By inserting and fixing the clamping rings in the hole 1 and the hole 2 respectively, in order to avoid the occurrence of cracks when the hook 1 and the hook 2 are fixing the film, after the punching is completed, the clamping rings need to be punched into the different holes 1 and the hole 2, and then the clamping rings are clamped and fixed from the back with the rings. In this way, when the hook 1 and the hook 2 are clamped into the hole 1 and the hole 2 respectively, the film will not be torn due to the lack of force points, and other structures can also be assisted to fix the film; BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Specifically, as Figure 1 , Figure 2 and Figure 3As shown, a hook 2 16 is hinged at the end of the insertion rod 15. According to the specifications of the film 10 to be fixed in the frame 1, the main gear plate 4 is first turned around, and the auxiliary gear plates 5 on both sides are pushed by the main gear plate 4.
