After the inner side of the platform surface of the T-shaped platform 7 is clamped into the clamping groove 6, it is clamped by the clamping part 13. After the movable lock 2 rotates, it cooperates with the buckle 1 to clamp the T-shaped platform 7.

[0020] The main body of the buckle 1 is an inverted L-shaped structure, which includes a horizontal portion 11 and a vertical portion 12; the clamping portion 13 is arranged on the front end bottom surface of the horizontal portion 11, and the movable locking member 2 is movably connected to the vertical portion 12, a part of the movable locking member 2 extends under the horizontal portion 11, and the other part extends outward from the vertical portion 12.

[0021] The movable locking member 2 includes a mounting arm 21 and a clamping arm 22. The clamping arm 22 is connected to the front end of the mounting arm 21, and the clamping arm 22 is inclined and bent upward relative to the mounting arm 21 to form an obtuse angle. The preferred angle is 120-160 degrees, such as 150 degrees. The mounting arm 21 is movably assembled with the vertical portion 12 of the buckle 1.

[0022] A pressing plate 3 is disposed at the front end of the pressing arm 22 . When the mounting arm 21 is pressed downward, the pressing plate 3 moves upward to press the bottom surface of the T-shaped platform 7 .

[0023] The surface of the pressing plate 3 is provided with an anti-skid portion 31 , which covers the entire surface of the pressing plate 3 . The pressing plate 3 presses the bottom surface of the T-shaped platform 7 with its anti-skid portion 31 to prevent slipping.

[0024] A through slot 14 is provided on the vertical portion 12 , and fixing ears 15 are provided along both sides of the through slot 14 . The clamping arm 22 penetrates the fixing ears 15 through the axle pin 4 to form a pivot assembly structure, so that the movable locking member 2 can perform a lever-like rotation movement.

[0025] The clamping portion 13 is bent downward and backward from the front end of the horizontal portion of the fastener 1 to form a flat L-shaped structure. The slot 6 is formed between the front end of the horizontal portion 11 and the clamping portion 13 . The height of the slot 6 is adapted to the thickness of the T-shaped platform 7 .

[0026] A limiting portion 16 protruding downward is provided on the bottom surface of the horizontal portion 11 of the buckle 1 , and the limiting portion 16 abuts against the rear edge of the T-shaped platform 7 to improve the stability of the anchoring.

[0027] A fixing hole 23 is provided at the rear of the mounting arm 21 , through which a connecting ring 5 is mounted, and the safety belt is locked on the connecting ring 5 by a movable buckle.

[0028] The buckle 1 and the movable lock 2 are both made of metal material, such as 0Cr19Ni9N stainless steel with a thickness of 10 mm. The bottom surface of the horizontal portion 11 of the buckle 1 is knurled; the clamping portion 13 and the main body of the buckle 1 are an integral structure, and the pressure plate 3 and the movable lock 2 are an integral structure.

[0029] When in use, first push the mounting arm 21 upwards to move the pressure plate 3 downwards to open the clamping space. Buckle the clip 1 onto the T-shaped platform 7 so that its inner edge is inserted into the slot 6, and the clamping portion 13 clamps the bottom surface of the inner edge of the T-shaped platform 7. Then press the mounting arm 21 downwards to move the pressure plate 3 to press against the bottom surface of the horizontal portion 11 of the clip 1, and the entire device is clamped onto the T-shaped platform 7. Buckle up the safety belt. Since the safety belt is located lower than the mounting arm 21, the direction of the pulling force is downwards, so that the movable lock 2 can be pulled downwards all the time, thereby ensuring that the entire device is always in a reliable locking state.

[0030] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention.
