For those skilled in the art, the specific meanings of the above terms can be understood according to the specific circumstances.

[0025] Embodiment one,

[0026] As Figures 1-2 shown, a hook of the present application comprises:

[0027] The hook parent body 1 has at least two bearing surfaces 11 with different diameters, and the number of bearing surfaces 11 and the diameter of the circular arc of the bearing surface 11 can be determined according to the main cable size in the actual workshop.

[0028] The hook child body 2 has a bending part 21 corresponding to the bearing surface 11, and the hook child body 2 is rotationally connected to the hook parent body 1. The hook parent body 1 is provided with three gear recesses 12, and one end of the hook child body 2 is clamped into the corresponding gear recess 12 to change the bearing radius formed by the bearing surface 11 and the bending part 21. At the same time, the diameters of the bearing surfaces 11 of the hook parent body 1 are arranged from small to large, so that the hook can be suitable for more cable sizes, and at the same time, the structural characteristics of the hook child body 2 and the hook parent body 1 are also met.

[0029] In the embodiment, to ensure the convenience of installation of the hooks, the two end faces or the two ends of the bottom face of the hook parent body 1 are provided with symmetrically arranged clamping grooves 13 for being connected with the open bridge. Under the premise of ensuring the structural strength, a plurality of lightening grooves are arranged on the hook parent body 1.

[0030] In the embodiment, to avoid the hooks from falling out and ensure the stability of the installation of the hooks, the other end of the hook child body 2 extends a pressing part 22 matched with the clamping groove 13. When the one end of the hook child body 2 is clamped into the corresponding gear recess 12, the pressing part 22 is close to the clamping groove 13, and the pressing part 22 at the other end is tightly pressed against the connecting rod 3 of the open bridge, thereby avoiding the hooks from falling out.

[0031] In the embodiment, to reduce the vibration resistance of the laid cable, the bearing face 11 and the bending part 21 are in arc shape, and the bearing face 11 has a certain width; the corresponding bending part 21 has two symmetrically arranged bending bodies. The wider bearing face 11 makes the cable in linear contact or surface contact with the bearing face 11, thereby increasing the contact area and ensuring that the cable is firmly fixed between the bearing face 11 and the bending part 21.

[0032] In the embodiment, to further strengthen the fixing effect of the cable, the hook child body 2 is an elastic body, and the bearing face 11 is provided with a buffer pad. The elastic deformation of the hook child body 2 and the buffer pad makes the cable fixed firmly.

[0033] Embodiment two,

[0034] As shown in Figures 3-4 Fig. 2, the utility model relates to an open bridge, which comprises a bridge body, the bridge body comprises a plurality of parallel U-shaped rods and eleven longitudinal connecting rods 3, and the hook of any one of the embodiments is applied.

[0035] In the production of the hook and the bridge, the distance between the clamping grooves 13 and the distance corresponding to the connecting rods 3 are determined, so that the hook is clamped with any two connecting rods 3. For example, the hook can be clamped on the adjacent connecting rods 3 on the side, or the connecting rods 3 on the side and the bottom, or the connecting rods 3 on the opposite side.

[0036] In some other embodiments, to facilitate the vertical installation of the hook, an extension baffle 111 can also be arranged between the bearing faces 11. The arc-shaped size of the extension baffle 111 is the same as that of the bearing face 11. When the hook is vertically installed, the cable placed on the bearing face 11 is not easy to slide out due to the existence of the extension baffle 111.

[0037] In other embodiments, for the convenience of installation of the hook parent body 1, the hook is completely fixed, the clamping grooves 13 are arranged in the same direction, the installation is facilitated, and meanwhile, the clamping grooves 13 arranged in the same direction (i.e., the other clamping groove not pressed by the pressing part of the hook child body 2) can be provided with other locking mechanisms, such as the common mother-son buckle structure.

[0038] The working principle of the utility model is as follows:

[0039] When the open type bridge and the hook of the utility model are used, the bridge body is arranged according to the bridge layout drawing, the fixing of the bridge body is realized by hoisting, bottom support or side support through the U-shaped rod or the connecting rod 3, when the cable is laid, the hook is clamped on the connecting rod 3 at the corresponding position, then the cable with the corresponding size is sequentially placed into the bearing surface 11, then one end of the hook child body 2 is clamped into the appropriate gear recess 12, and the pressing part at the other end of the hook child body 2 is abutted on the connecting rod 3, so that the fixing of the hook is completed in cooperation with the clamping groove 13, and the hook is prevented from falling off due to vibration and other external factors.

[0040] In this process, the elastic deformation of the hook child body 2 and the buffer pad further enhances the fixing effect of the cable, compared with the conventional open type bridge using the cable tie to fix the cable, the flexibility and laying speed during laying are greatly increased, the regularity after laying is higher, and unlike the cable tie which can only be destructively cut and removed, the hook of the utility model can be repeatedly used, and the installation and disassembly can be conveniently and quickly completed without the need of carrying additional tools.

[0041] The above embodiments are only used to illustrate the technical solutions of the utility model and not to limit, although the utility model is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the utility model can be modified or replaced equivalently without departing from the purpose and scope of the technical solutions of the utility model, and all should be covered in the claim range of the utility model. The technical, shape and structure parts not described in detail in the utility model are all known technologies.
