Description

Technical Field

[0001] The invention relates to the technical field of clamps, and in particular to an auxiliary device for installing a clamp. Background Art

[0002] During the assembly and maintenance of domestic military and civilian aircraft systems, a large number of clamps are needed to fix and install various pipes and wiring harnesses. The most commonly used ones are R-type rubber strip clamps. At present, the process of clamp installation is: first use needle-nosed pliers to clamp the end of the clamp body to temporarily close the clamp body, then insert the clamp screw into the connection hole at the end of the clamp body, and finally tighten it with the clamp nut. The existing clamp installation method is relatively complicated to operate, and it is not convenient to install in narrow places. In addition, needle-nosed pliers will damage the surface coating of the clamp body, affecting the appearance and corrosion resistance of the clamp. Summary of the invention

[0003] The technical problem solved by the invention is to provide an auxiliary device for installing a clamp which is convenient for installing the clamp and has less damage to the clamp.

[0004] The technical solution adopted by the present invention to solve the technical problem is: an auxiliary device for installing a clamp comprises a pre-fixing plate, and a pre-fixing groove is arranged on the pre-fixing plate.

[0005] Furthermore, the pre-fixing slot is arranged at one end of the pre-fixing sheet.

[0006] Furthermore, the pre-fixed slot is U-shaped.

[0007] Furthermore, the width of the pre-fixing slot is between the minor diameter and the middle diameter of the thread of the clamp screw.

[0008] Furthermore, the end of the pre-fixing piece provided with the pre-fixing slot is arc-shaped.

[0009] Furthermore, at least two pre-fixing slots are provided on the pre-fixing sheet, and the widths of the pre-fixing slots are different.

[0010] Furthermore, a hanging hole is provided on the pre-fixing plate, and the hanging hole and the pre-fixing slot are respectively located at the left and right ends of the pre-fixing plate.

[0011] The beneficial effects of the present invention are as follows: the auxiliary device for installing the clamp of the present invention comprises a pre-fixing plate, on which a pre-fixing slot is arranged. When the auxiliary device is used to install the clamp, the clamp screw is first passed through the connecting holes at both ends of the clamp body, and then the pre-fixing slot of the auxiliary device is inserted into the thread of the clamp screw, so that the clamp body is in a temporary closed state, and finally the clamp nut is screwed onto the clamp screw, and when the clamp nut is about to contact the pre-fixing plate, the auxiliary device is removed, and the clamp nut is continuously rotated until it is tightened to the final state. The auxiliary device has a simple structure, is convenient for installing the clamp, is particularly suitable for R-type rubber strip clamps, and is more convenient for installing the clamp in narrow places, effectively reduces the damage to the surface coating of the clamp body, and ensures the normal use of the clamp.

[0016] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] like Figure 1 , Figure 2 As shown, the auxiliary device for installing a clamp of the present invention comprises a pre-fixing plate 1 on which a pre-fixing groove 2 is arranged.

[0018] When the auxiliary device is used to install the clamp, firstly, the clamp screw 5 is passed through the connection holes at both ends of the clamp body 4, and then the pre-fixing slot 2 of the auxiliary device is inserted into the thread of the clamp screw 5, so that the clamp body 4 is in a temporary closed state. Figure 3 As shown, the clamp nut is finally screwed onto the clamp screw 5. When the clamp nut is about to contact the pre-fixing plate 1, the auxiliary device is removed, and the clamp nut is continued to be rotated until it is tightened to the final state. The auxiliary device has a simple structure and is convenient for the installation of the clamp. It is particularly suitable for R-type rubber strip clamps and is more convenient for the installation of clamps in narrow places. It effectively reduces the damage to the surface coating of the clamp body 5 and ensures the normal use of the clamp.

[0019] Specifically, the pre-fixing plate 1 is rectangular in shape and can be made of carbon steel, stainless steel, etc. In order to facilitate its use, the pre-fixing slot 2 is arranged at one end of the pre-fixing plate 1. Figure 1 , Figure 2 As shown in FIG. 1 , the pre-fixing slot 2 is arranged at the left end of the pre-fixing sheet 1. In order to reduce damage to other components, the end of the pre-fixing sheet 1 provided with the pre-fixing slot 2 is arc-shaped.

[0020] Since the shape of the clamp screw 5 is usually cylindrical, in order to improve the use effect of the pre-fixing slot 2, the shape of the pre-fixing slot 2 is U-shaped, and the width of the pre-fixing slot 2 is between the minor diameter and the middle diameter of the thread of the clamp screw 5.

[0021] In order to make the pre-fixing plate 1 suitable for clamp installation of clamp screws 5 with different diameters, at least two pre-fixing slots 2 are provided on the pre-fixing plate 1, and the widths of the pre-fixing slots 2 are different.

[0022] In order to facilitate carrying and placing the auxiliary device in daily life, a hanging hole 3 is provided on the pre-fixing plate 1 , and the hanging hole 3 and the pre-fixing slot 2 are respectively located at the left and right ends of the pre-fixing plate 1 .
