[0019] 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.
[0020] See also Figures 1 to 4 In the embodiment of the utility model, a closed structure of a rock climbing carabiner comprises a long hook 1 and a short section 2. One end of the short section 2 is rotatably connected to an open end of the long hook 1 through a fixing pin 3, and the other end of the short section 2 is engaged with the other end of the opening of the long hook 1. A locking mechanism is arranged on the outer wall of the short section 2; the locking mechanism comprises a locking cap 4, a large spring 5, a fixing bar 6, a small spring 7, a limiting groove 8, an annular groove 9, a buffer groove 10, a fixing groove 11, and an unlocking groove 12; the locking cap 4 is slidably connected to the outer wall of the short section 2, the large spring 5 is arranged in the gap between the short section 2 and the locking cap 4, two fixing grooves 11 and unlocking grooves 12 are arranged, two fixing grooves 11 are symmetrically arranged at the bottom of the locking cap 4, two unlocking grooves 12 are symmetrically arranged at the bottom of the locking cap 4, and the fixing grooves 11 and the unlocking grooves 12 are staggered and distributed on the bottom of the locking cap 4; the annular groove 9 is arranged at the locking cap 4, two buffer grooves 10 are provided, and the two buffer grooves 10 are symmetrically opened on the inner wall of the top of the locking cap 4, and the bottom of the buffer groove 10 is connected with the annular groove 9; the limiting groove 8 is opened at the top of the short section 2, the fixing strip 6 is vertically slidably connected to the limiting groove 8, and the two ends of the fixing strip 6 are horizontally slidably connected in the annular groove 9, the top of the small spring 7 is fixedly connected to the bottom of the fixing strip 6, and the bottom of the small spring 7 is fixedly connected to the inner wall of the bottom end of the limiting groove 8; the locking mechanism also includes a limiting strip 13 and a protrusion 14, the protrusion 14 is fixedly connected to the top center of the fixing strip 6, and a hole matching the protrusion 14 is opened at the bottom of one end of the long hook 1 and the short section 2, and two limiting strips 13 are provided, and the two limiting strips 13 are formed at the top of the limiting groove 8, and the two limiting strips 13 are respectively engaged with the two grooves at the top of the fixing strip 6 and symmetrically distributed on both sides of the protrusion 14.
[0021] In this embodiment: It is necessary to add that: Figure 1 The middle state is a normally closed state;
[0022] When it is necessary to unlock the carabiner, slide the locking cap 4 upward to disengage the fixing pin 3 from the fixing groove 11, and then rotate the locking cap 4 to make the fixing pin 3 slide along the bottom of the locking cap 4 and finally slide into the unlocking groove 12. At the same time, both ends of the fixing strip 6 slide along the annular groove 9 and finally align with the buffer groove 10. At this time, slide the locking cap 4 down again, the large spring 5 will be compressed, and the end of the short section 2 engaged with the long hook 1 will gradually leak out. At the same time, the inner wall of the top end of the buffer groove 10 will approach the top of the fixing strip 6. When the top of the buffer groove 10 fits the top of the fixing strip 6, continue to slide the locking cap 4 down, the locking cap 4 will drive the fixing strip 6 to move downward, so that the protrusion 14 is separated from one end of the long hook 1. When the two are separated, the fixing pin 3 contacts the top of the unlocking groove 12. At this time, the closure of the carabiner is released, and the short section 2 can be toggled to separate one end of the short section 2 from the long hook 1, thereby opening the carabiner.
[0023] After that, the short section 2 is loosened, and the short section 2 automatically rebounds and engages with one end of the long hook 1. At this time, the carabiner is in an unlocked state, and the locking cap 4 can be further rotated to make the fixing pin 3 engage in the grooves raised on both sides of the unlocking groove 12, so that the locking cap 4 is in a normally unlocked state. This state is suitable for scenes where the rope is frequently moved and changed (it should be supplemented that the inner diameter of the locking cap 4 is larger than the diameter of the end of the rotation connection between the long hook 1 and the short section 2 (such as Figure 1 ), so that after the locking cap 4 moves down, there is space between the locking cap 4 and the end of the long hook 1, thus providing conditions for the rotation of the short section 2);
[0024] When it is necessary to keep the carabiner in a locked state, continue the above operation, rotate the locking cap 4, so that the fixing pin 3 slides out of the groove on one side of the unlocking groove 12, and the large spring 5 returns to its original position and rebounds, pushing the locking cap 4 to automatically move up to complete the closure of the engaging end of the short section 2 and the long hook 1, and then rotate the locking cap 4 to make the fixing pin 3 slide along the bottom of the locking cap 4, so that the fixing pin 3 slides out of the unlocking groove 12 and slides into the fixing groove 11. At this time, the locking cap 4 is in a normally locked state.
[0025] Please refer to Figures 1 to 4 The height of the unlocking groove 12 is consistent with the length of one end of the short section 2 and the long hook 1 that are engaged.
[0026] In this embodiment, it is ensured that when the fixing pin 3 slides to the top of the unlocking groove 12, the end of the short section 2 and the long hook 1 that are engaged with each other completely leaks out.
[0027] Please refer to Figures 2-3 The height of the fixing strip 6 is less than the height of the annular groove 9 , and the distance between the bottom of the fixing strip 6 and the inner wall of the bottom end of the annular groove 9 is greater than the radius of the fixing groove 11 .
[0028] In this embodiment: when the locking cap 4 is unlocked from the normally locked state, it is necessary to slide the locking cap 4 upward first to disengage the locking cap 4 from the fixing groove 11. The height of the fixing strip 6 is less than the height of the annular groove 9 to ensure that when the locking cap 4 moves, the fixing strip 6 has space to move downward and will not interfere with the locking cap 4.
[0029] Please refer to Figure 4 The buffer groove 10 and the unlocking groove 12 are located on the same straight line, and the arc width of the buffer groove 10 is consistent with the arc width of the unlocking groove 12.
[0030] In this embodiment, it is ensured that when the locking cap 4 rotates, the fixing pin 3 is aligned with the unlocking groove 12 , and both ends of the fixing strip 6 are aligned with the buffer groove 10 .
[0031] Please refer to Figure 4 The height of the annular groove 9 is smaller than the height of the unlocking groove 12 , and the vertical distance from the inner wall of the bottom end of the limiting groove 8 to the inner wall of the top end of the buffer groove 10 is greater than the height of the unlocking groove 12 .
[0032] In this embodiment: when the locking cap 4 slides down to unlock, when the locking cap 4 slides down to the bottom, the locking cap 4 drives the fixing bar 6 to move downward through the buffer groove 10, so that the protrusion 14 is separated from one end of the long hook 1, so that one end of the short section 2 can be separated from one end of the long hook 1.
[0033] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
