[0033] Before introducing in detail, it is necessary to understand the application scenarios of the utility model. The bridge is often laid in different environments and often needs to pass through complex working environments, such as high temperature, high humidity, dusty, oily areas, etc., and the cable has a large weight. Especially when multiple cables are laid simultaneously, the bridge needs to have sufficient strength and stability. Therefore, if you encounter a problem such as a hollow wall or a thin wall where the installation environment is not good and it is not easy to fix, you need to apply the technical solution of the utility model.

[0034] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] like Figure 1-4 As shown, it is a schematic diagram of the overall structure of the utility model:

[0036] A hollow wall bridge fixing hook is composed of a hook body 1, a riveted body 5 and a truncated cone 8. The hook body 1 includes a hook portion 2, a screw portion 3 and a nut 4. The riveted body 5 is coaxially arranged with the screw portion 3. The riveted body 5 includes a sleeve 6 and an exhibition board 7. The truncated cone 8 has an internal thread and is threadedly connected with the screw portion 3. The hook portion 2 is used to hang a bridge support or a bridge body. Its shape is designed to be an arc hook type, which is convenient for the installation and fixation of the bridge support or the bridge body. The screw portion 3 has an external thread so as to be used in conjunction with the internal thread of the truncated cone 8. The nut 4 is fixed on the screw portion 3, generally a flat head nut 4, and the rotation of the nut 4 will drive the rotation of the screw portion 3. The sleeve 6 is sleeved on the screw portion 3, and its height is not greater than the thickness of the plate to be fixed, so as to ensure that the sleeve 6 is tightly fitted with the plate to be fixed. The exhibition board 7 is arranged on the sleeve 6, and a plurality of exhibition boards 7 are enclosed around the outer periphery of the screw portion 3 to form a stable support structure. The truncated cone 8 has an internal thread and is threadedly connected to the screw portion 3 to ensure a close fit between the truncated cone 8 and the screw portion 3. The bottom diameter of the truncated cone 8 is larger than the inner diameter of the arc formed by the multiple display panels 7, which helps to improve the stability and load-bearing capacity of the overall structure.

[0037] During operation, drill a suitable hole in the hollow wall, with the hole size matching the sleeve 6. Place the hollow wall bridge fixing hook into the hole, with the upper edge of the sleeve 6 flush with the edge of the hole. Tighten the nut 4 of the hook body 1 to tighten the screw part 3 and the internal thread of the frustum 8 in the positive direction. Apply force to keep the nut 4 and the sleeve 6 in contact, and twist the nut 4 in the opposite direction to drive the screw part 3 to rotate in the opposite direction. With the thread matching, the frustum 8 moves toward the nut 4. The frustum 8 pushes into the intermittent arc surface enclosed by multiple display panels 7, and pushes the multiple display panels 7 outward to apply destructive force. Multiple display panels 7 are turned outward to complete the extrusion and fixation of the hollow wall.

[0038] It should be noted that the display board 7 is preferably composed of an upper board 9 and a lower board 10. The upper board 9 and the lower board 10 are made of the same material and are integrally formed. A bite seam 11 is provided between two adjacent upper boards 9, and the bite seam 11 is formed into a fold line in the longitudinal direction, so that the two adjacent upper boards 9 are closely connected and integrated when not deformed; when deformed, they can be more stable. The specific shape and size of the bite seam 11 are adjusted according to actual needs.

[0039] Furthermore, two adjacent lower plates 10 are not completely in contact, but a gap 12 is provided therebetween, the gap 12 extends toward the tail of the screw portion 3, the width of the gap 12 is narrow near the tail of the screw portion 3, and gradually widens away from the tail of the screw portion 3. When the truncated cone 8 is forced to move toward the nut 4, the gap 12 with a narrow top and a wide bottom is conducive to the movement of the truncated cone 8. Moreover, the gap 12 is narrow at the top and wide at the bottom, which can reduce the interference of the lower plate 10 on the truncated cone 8 and ensure the normal operation of the truncated cone 8.

[0040] It should be noted that the side hook 13 is provided at the end of the lower plate 10, and the protrusion 14 is provided at the upper end of the truncated cone 8. Every two side hooks 13 enclose an open groove for accommodating the protrusion 14, which limits the protrusion 14 and helps prevent the truncated cone 8 from separating from the screw portion 3. On the other hand, when the truncated cone 8 is forced to move toward the sleeve 6, the protrusion 14 moves toward the sleeve 6 along the gap 12, playing a certain guiding role.

[0041] It should be noted that, in order to increase the force bearing area, the gasket 15 is arranged at the upper end of the sleeve 6. The lower end of the gasket 15 is located on the surface of the wall or board to be fixed, and the sleeve 6 is located in the hole of the wall or board to be fixed. The area of ​​the gasket 15 is larger than the area of ​​the sleeve 6.

[0042] Furthermore, an inner groove 16 is provided at the connection between the upper plate 9 and the lower plate 10. The inner groove 16 is a groove body that is recessed toward the screw rod, and the inner groove 16 is perpendicular to the axis of the screw rod portion 3. The strength of the inner groove 16 is weakest compared with that of the upper plate 9 and the lower plate 10. Its design ensures the stability of the upper plate 9 and the lower plate 10 during movement and helps the deformation of the upper plate 9 and the lower plate 10.

[0043] It should be pointed out that the addition of a hoop 17 sleeved on the inner groove 16 helps to balance and uniform the upper plate 9 and the lower plate 10 during the deformation process. It prevents uneven force, which may cause one display board 7 to deform while other display boards 7 are not deformed, resulting in unstable fixation or even damage to the fixed structure. The hoop 17 is not an integral ring, but has an opening or is spiral. When the lower plate 10 is expanded to a certain extent under force and still cannot meet the tightening requirements, the upper plate 9 expands and deforms. Therefore, the hoop 17 is relaxed to a certain extent to accommodate the deformation of the upper plate 9.

[0044] Furthermore, the hook portion 2, the screw portion 3 and the nut 4 are integrally formed, so as to enhance the stability and prevent damage when subjected to force.

[0045] It should be pointed out that the sleeve 6 and the expansion plate 7 are used as the key force-bearing expansion mechanism, and the one-piece molding arrangement has good stability and durability, which effectively improves the stability and durability of the overall structure.

[0046] It should be pointed out that the thickness of the display board 7 is smaller than the thickness of the sleeve 6. The sleeve 6 is a fixing member for connecting the display board 7 and is sleeved on the screw part 3. Its function is to abut against the wall or thin plate to be fixed. Its required characteristics are stability and firmness, so sufficient strength is required. The display board 7 is used as an extension deformation expansion. Its function is to expand and compress the hole of the wall or thin plate to be fixed to achieve fixation. Therefore, too much strength is not conducive to its deformation.

[0047] In summary, the hollow wall bridge fixing hook of the utility model, through the specific description of the above embodiments, demonstrates the novelty and practicality of its structural design. It is not only easy to install and maintain, but also has a stable structure, high bearing capacity and good performance, and is suitable for the needs of cable laying and protection in various occasions.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
