DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 7As shown, a spring hook fixing installation mechanism comprises a mounting seat 10, a first clamping mechanism 4 mounted on the mounting seat 10, the first clamping mechanism 4 is used to clamp a spring hook short section 20, a spring washer 201 is mounted in the spring hook short section 20, an adjusting mechanism 5 is also mounted on the mounting seat 10, the adjusting mechanism 5 comprises a first cylinder 102 mounted on the mounting seat 10, a moving plate 51 is provided on the first cylinder 102, an adjusting head 52 for positioning and adjusting the position of the spring washer 201 is extended on the moving plate 51, a groove for the adjusting head 52 to enter is provided on the spring hook short section 20, the spring washer 201 needs to cooperate with the groove on the spring hook long section 2, the direction of the spring washer 201 is adjusted by the adjusting head 52, so as to ensure that the spring washer 201 can always cooperate with the groove on the spring hook long section 2, and the adjusting mechanism 5 has a simpler structure.

[0025] The first clamping mechanism 4 includes a fixed block 41, a slide groove 411 is provided in the fixed block 41, the slide groove 411 is "T" shaped, a push block is slidably installed in the slide groove 411, two rotating shafts 42 are provided on the fixed block 41, and clamping blocks 43 are rotatably provided on the outer circumference of the rotating shafts 42, and clamping parts are extended on the clamping blocks 43, and the other ends of the clamping blocks 43 are abutted and matched with the push block, and a first spring 44 is provided between the push block and the fixed block 41, and the first spring 44 always has a tendency to push the push block to move toward the side close to the clamping block 43;

[0026] When the push block moves toward the side close to the clamp block 43, the clamping parts swing toward the side close to each other;

[0027] When the push block moves away from the clamp block 43, the clamping parts swing away from each other.

[0028] The installation is completed by installing the pushing block into the slide groove 411, installing the first spring 44 between the fixed block 41 and the pushing block, inserting the two rotating shafts 42 into the clamping blocks 43 respectively, and finally fixing the rotating shafts 42 to the fixed block 41, which is more convenient.

[0029] The clamping blocks 43 are each provided with a connecting rod 45, and a second spring (not shown in the figure) is connected between the connecting rods 45. In the present application, the second spring has connecting rings at both ends. When installed, the connecting rings at both ends are respectively sleeved on the outer circumference of the two connecting rods 45. The second spring always has a tendency to swing the two clamping parts away from each other, so that when the push block and the clamping block 43 are out of contact, the clamping part releases the short section of the carabiner, so that the processed short section of the carabiner falls by itself by gravity.

[0030] The elastic force of the first spring 44 is greater than the elastic force of the second spring, so that the push block is always in contact with the clamping block 43, so that during the processing, the clamping part always clamps the carabiner short section, so that the carabiner short section will not fall off during the processing.

[0031] The clamping part has a clamping opening 431, the shape of which is adapted to the short section of the carabiner, so that the short section of the carabiner can be better clamped and fixed, and a rubber pad can be installed on the surface of the clamping opening 431 to increase the friction when clamping the short section of the carabiner, so that the short section of the carabiner is more secure when clamped and will not fall off.

[0032] The clamping block 43 has a slope 432 at one end close to the pushing block, and the pushing block has a pushing portion at one end that abuts against the inclined groove. The pushing portion is an isosceles trapezoid in the present application, and can also be an isosceles triangle in addition to the isosceles trapezoid, and there is an angle between the pushing portion and the contact surfaces of the two slopes 432. When the clamping portion is in a clamping state, the two clamping portions contact each other, and at this time the angle between the two slopes 432 is at a maximum value, and at this time the angle between the two slopes 432 is smaller than the angle between the pushing portion and the contact surfaces of the two slopes 432, thereby ensuring that when the pushing block is located at the extreme position close to one side of the clamping block 43, the angle between the two slopes 432 is at a maximum value, thereby ensuring that the force of the clamping portion when clamping the short section of the carabiner is at a maximum value.

[0033] The pushing block has a spring cavity (not shown in the figure) for positioning and installing the first spring 44, so that the first spring 44 can be better positioned and installed.

[0034] A base 1 is installed on the mounting seat 10, and a support frame 11 is installed on the base 1. The support frame 11 is used to place the spring hook section 2 to be installed.

The first clamping arm 1041 has a first matching groove 1043 adapted to the spring hook section 2, and the second clamping arm 1042 has a second matching groove 1044 adapted to the long groove of the spring member, so that when the clamping cylinder 104 is started to clamp the spring hook section 2 through the first clamping arm 1041 and the second clamping arm 1042, the clamping effect is better.
