Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0040] In an embodiment of the present utility model, please refer to Figures 1 to 4 , a connection buckle for a safety belt in high-altitude operation construction, including a clamping seat 1 and a buckle 2. The buckle 2 is inserted into the interior of the clamping seat 1.

The two-layer fixing mechanism fixes the buckle 2 to ensure safety and avoid unhooking. The unlocking mechanism unlocks the fixing mechanism 1 and the fixing mechanism 2.

[0045] As an embodiment of the present invention, please refer to Figure 1 , the fixing mechanism 1 includes:

[0049] The elastic member 1 8 is arranged inside the connecting sleeve 1 5, one end is connected to the other end of the sliding rod 6, and the other end is connected to the inner wall of the card seat 1.

[0050] During the process of inserting the buckle 2 into the card seat 1, the buckle 2 presses the clamping block 7, so that the clamping block 7 drives the sliding rod 6 to move linearly along the connecting sleeve 1 5, and the elastic member 1 8 undergoes elastic deformation. When the buckle 2 is completely inserted into the card seat 1, the clamping block 7 and the fixing hole 1 3 are on the same horizontal line. Under the reaction force of the elastic member 1 8, the clamping block 7 is clamped with the fixing hole 1 3 to fix the buckle 2. The elastic member 1 8 can be a spring, a spring sheet, etc.

[0051] As an embodiment of the present invention, please refer to Figure 1 and Figure 3 , the fixing mechanism 2 includes:

[0052] The connecting sleeve 2 20 is connected to the inner wall of the card seat 1;

[0053] The sliding clamping rod 19 is slidably connected to the connecting sleeve 2 10 and is clamped with the fixing hole 2 4;

[0054] The elastic member 2 21 is arranged inside the connecting sleeve 2 20, one end is connected to the sliding folding rod 19, and the other end is connected to the connecting sleeve 2 20.

[0055] During the process of inserting the buckle 2 into the card seat 1, the buckle 2 presses the sliding clamping rod 19, so that the sliding clamping rod 19 moves horizontally, and the elastic member 2 21 undergoes elastic deformation. When the buckle 2 is completely inserted into the card seat 1, the sliding clamping rod 19 and the fixing hole 2 4 are on the same horizontal line. Under the reaction force of the elastic member 2 21, the sliding clamping rod 19 is clamped with the fixing hole 2 4 to fix the buckle 2. The elastic member 2 21 can be a spring, a spring sheet, etc.

[0056] As an embodiment of the present invention, please refer toFigure 1 , Figure 2 and Figure 4 , the unlocking mechanism includes:

[0057] Connecting plate 9, connected to one side of the sliding rod 6 close to the fixture block 7;

[0058] Sliding folding rod 10, slidably connected to the card seat 1 and abutted against one side of the connecting rod 9 close to the fixture block 7;

[0059] Connecting rod 11, one end rotatably connected to the sliding folding rod 10;

[0060] Connecting frame 12, connected to the other end of the connecting rod 11;

[0061] Toothed ring 14, slidably connected to the outer wall of the connecting frame 12, and the toothed ring 14 is rotatably connected to the card seat 1;

[0062] Rotating assembly, one end connected to the card seat 1 and the other end connected to the connecting rod 11;

[0063] The rotating assembly includes:

[0064] Folding groove 13, opened on the connecting frame 12, and the folding groove 13 is L-shaped;

[0065] Fixed clamping rod 17, connected to the card seat 1 and movably clamped with the folding groove 13;

[0066] Elastic right-angle plate 16, one end connected to the card seat 1;

[0067] Limiting tooth 15, connected to the other end of the elastic right-angle plate 16 and clamped with the teeth on the toothed ring 14;

[0068] Bump 18, connected to the connecting rod 11.

[0069] When it is necessary to separate the buckle 2 from the card seat 1, the staff presses the connecting frame 12. The connecting frame 12 drives the connecting rod 11 and the sliding folding rod 10 to move horizontally. The sliding folding rod 10 squeezes the connecting plate 9, and the connecting plate 9 drives the sliding rod 6 to move, so that the fixture block 7 is separated from the first fixing hole 3. At this time, the fixed clamping rod 17 abuts against the turning point of the folding groove 13, and the bump 18 abuts against the sliding clamping rod 19, and the connecting frame 12 is rotated to make the folding groove 13 clamped with the fixed clamping rod 17. At the same time, the connecting frame 12 drives the connecting rod 11 to rotate, and the connecting rod 11 drives the bump 18 to rotate, so that the bump 18 squeezes the sliding clamping rod 19 to both sides, so that the sliding clamping rod 19 is separated from the second fixing hole 4, and the fixing of the buckle 2 is released. During the rotation of the connecting frame 12, the connecting frame 12 drives the toothed ring 14 to rotate, and the limiting tooth 15 limits the toothed ring 14.

[0070] The working principle of the present utility model is as follows: During the process of inserting the buckle 2 into the card seat 1, the buckle 2 presses the clamping block 7, causing the clamping block 7 to drive the sliding rod 6 to move linearly along the first connecting sleeve 5, and the first elastic member 8 undergoes elastic deformation. When the buckle 2 is completely inserted into the interior of the card seat 1, the clamping block 7 and the first fixing hole 3 are on the same horizontal line. Under the reaction force of the first elastic member 8, the clamping block 7 and the first fixing hole 3 are clamped to fix the buckle 2.

[0071] The buckle 2 presses the sliding clamping rod 19, causing the sliding clamping rod 19 to move horizontally, and the second elastic member 21 undergoes elastic deformation. When the buckle 2 is completely inserted into the interior of the card seat 1, the sliding clamping rod 19 and the second fixing hole 4 are on the same horizontal line. Under the reaction force of the second elastic member 21, the sliding clamping rod 19 and the second fixing hole 4 are clamped.

[0072] When it is necessary to separate the buckle 2 from the card seat 1, the staff presses the connecting frame 12. The connecting frame 12 drives the connecting rod 11 and the sliding folding rod 10 to move horizontally. The sliding folding rod 10 presses the connecting plate 9, and the connecting plate 9 drives the sliding rod 6 to move, causing the clamping block 7 to disengage from the first fixing hole 3. At this time, the fixed clamping rod 17 abuts against the turning point of the folding groove 13, and the convex block 18 abuts against the sliding clamping rod 19 to rotate the connecting frame 12, causing the folding groove 13 to be clamped with the fixed clamping rod 17. At the same time, the connecting frame 12 drives the connecting rod 11 to rotate, and the connecting rod 11 drives the convex block 18 to rotate, causing the convex block 18 to squeeze the sliding clamping rod 19 on both sides, causing the sliding clamping rod 19 to disengage from the second fixing hole 4, releasing the fixation of the buckle 2. During the rotation of the connecting frame 12, the connecting frame 12 drives the toothed ring 14 to rotate, and the limiting tooth 15 limits the toothed ring 14.
