DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figures 2 to 6 As shown, a device for automatically installing a retaining spring for a carabiner includes a clamp 1 and a clamp handle 2 arranged on the outside of the clamp 1, and a guide portion 21 is provided at one end of the clamp handle 2; the clamp 1 includes a clamp base 11, a clamp body 12 fixed on the clamp base 11, and a fixed limit block 13 arranged on the clamp body 12. The aluminum hook is fixed by the fixed limit block 13, and the spring is guided to be clamped in the spring mounting hole on the aluminum hook by the guide portion 21 of the clamp handle 2 to complete the assembly of the carabiner.

[0026] In order to facilitate the assembly of the carabiner and increase the speed of assembling the carabiner, the clamp 1 and the clamp handle 2 are designed; Figures 2 to 4As shown, the clamp body 12 is provided with a plurality of through holes for the fixed limit block 13 to pass through, a spring installation groove 121 and an assembly operation groove 122 which are recessed downward from the upper end surface of the clamp body 12, and a disassembly groove 123 for separating the clamp base 11 and the clamp body 12; the shape of the through hole is the same as that of the fixed limit block 13, and the sizes correspond one to one, and the plurality of through holes are distributed around the spring installation groove 121 and are arranged at intervals around the spring installation groove 121; the spring installation groove 121 includes a spring expansion groove 1211 and a spring support groove 1212, and the spring expansion groove 1211 is connected to the upper and lower surfaces of the clamp body 12, so that the spring can be fully expanded when assembling the carabiner, and it is convenient to clip the spring into the spring installation hole on the aluminum hook; the spring support groove 1212 is located on the right side of the spring expansion groove 1211, and is used to support the part of the spring that does not need to be expanded, so that the spring can remain stable when assembling the carabiner, reducing the difficulty of operation. One end of the assembly operation slot 122 is connected to the spring expansion slot 1211, and the other end extends to the side wall of the clamp body 12. The plane where the assembly operation slot 122 is located is lower than the upper end surface of the clamp body 12, so that the clamp handle 2 can be inserted from the assembly operation slot 122 to control the expansion angle of the spring and guide the end of the spring to be inserted into the spring mounting hole in the aluminum hook. The disassembly slot 123 is set at the bottom of the clamp body 12, so that a gap is formed after the clamp body 12 and the clamp base 11 are fixed, which makes it convenient to insert the hand or other tools through the gap to separate the clamp body 12 and the clamp base 11. The bottom of the through hole is located in the gap, which facilitates the disassembly of the clamp body 12 and the clamp base 11, and the removal of the fixed limit block at the same time.

[0027] like Figures 2 to 5As shown, the fixed limit block 13 passes through the through hole on the clamp body 12, extending from the bottom of the clamp body 12 to the upper end surface of the clamp body 12, and the distance between the upper end of the fixed limit block 13 and the upper end surface of the clamp body 12 is greater than the thickness of the aluminum hook. An aluminum hook fixing cavity is formed between the multiple fixed limit blocks 13, and the aluminum hook fixing cavity is located directly above the spring mounting groove 121, so that the aluminum hook can be firmly fixed in the aluminum hook fixing cavity. When the spring and the aluminum hook are assembled, the part of the spring that needs to be expanded can be located on the spring expansion groove 1211, and the part of the spring that does not need to be expanded can be placed on the spring support The bottom of the fixed limit block 13 is provided with a fixed protrusion 131, and the upper part of the side wall near the aluminum hook fixing cavity is provided with a downward inclined surface 132; the thickness of the fixed protrusion 131 is the same as the depth of the disassembly groove 123, and the fixed protrusion 131 is located in the gap between the clamp body 12 and the clamp base 11, so that the clamp body 12 and the clamp base 11 can clamp the fixed protrusion, so that the fixed limit block 13 remains stable; the inclined surface 132 is inclined downward from the top of the fixed limit block 13 to the side wall near the aluminum hook fixing cavity, which can guide the aluminum hook downward to be fixed in the aluminum hook fixing cavity. In this embodiment, the number of the fixed limit blocks 13 is 5, and the shape of each fixed limit block 13 is different. The shape of the side wall of the fixed limit block 13 near the aluminum hook fixing cavity corresponds to the shape of the aluminum hook, so that the shape of the aluminum hook fixing cavity surrounded by multiple fixed limit blocks 13 is the same as the shape of the aluminum hook.

[0028] like Figure 6 As shown, one end of the clamp handle 2 is provided with a guide portion 21 for guiding the spring to be clamped into the spring mounting hole on the aluminum hook; the guide portion 21 includes a first clamping plate 211 and a second clamping plate 212, and the lower end surface of the first clamping plate 211 is on the same plane as the lower end surface of the clamp handle 2, and the second clamping plate 212 has the same structure as the first clamping plate 211, and is arranged above the first clamping plate 211 at intervals; the clamp handle 2 and the first clamping plate 211 and the second clamping plate 212 are an integrally formed structure; the spring is clamped by the spacing groove between the first clamping plate 211 and the second clamping plate 212, and the clamp handle 2 is pulled to expand the spring to a suitable angle, and the spring is aligned with the spring mounting hole on the aluminum hook by moving the clamp handle 2, and then the spring is released so that the spring is clamped into the spring mounting hole, completing the assembly of the aluminum hook and the spring. It is easy to operate and has strong practicality, which reduces the technical requirements and proficiency requirements for the operator.

[0029] The general working process of the present invention is as follows: the fixed limit block 13 is placed in the clamp body 12, and the clamp base and the clamp body are fixedly connected; then the aluminum hook formed by the processes of profile, sawing, vibration grinding, etc. is fixed in the aluminum hook fixing cavity; since the aluminum hook fixing cavity has the same shape as the aluminum hook, it can ensure that the aluminum hook is fixed on the clamp without loosening; then one end of the spring is placed in the spring mounting hole on the aluminum hook; one side of the spring is clamped by the guide part 21 of the clamp handle 2, and then the clamp handle 2 is pulled to make the expansion angle of the spring greater than the thickness of the aluminum hook, and the clamp handle is moved. 2. Align the spring with the spring mounting hole and insert it into the spring mounting hole to complete the assembly of the aluminum hook and the spring; the clamp handle 2 can better control the expansion angle of the spring to prevent the spring from being deformed due to excessive force; since the aluminum hook fixed in the aluminum hook fixing cavity and the assembly operation groove 122 have a height difference, the operator can grab the assembled carabiner from the assembly operation groove 122 and conveniently remove it from the aluminum hook fixing cavity; repeating the above process can quickly complete the assembly process of the carabiner, improve production efficiency, and reduce the probability of spring deformation.
