DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-5 A frame safety belt safety bolt comprises a bolt body 10 and a socket 20. A slot 201 is provided in the middle of the lower end of the socket 20. The size of the slot 201 matches the size of the bolt body 10. The socket 20 is movably sleeved on the upper end of the bolt body 10, and a connecting ring 30 is fixed on the upper end of the socket 20. The outer portion of the connecting ring 30 is sleeved with a safety belt body 40. A notch for inserting the bolt body 10 is pre-set on the frame. The size of the notch should match the size of the bolt body 10. The lower end of the bolt body 10 is first inserted into the notch, and the bolt body 10 can be fixed with bolts.

[0025] The latch body 10 is connected to the sleeve 20 through a locking mechanism, and the locking mechanism includes a first socket 101, a second socket 204 and a positioning pin assembly 50. The first socket 101 and the second socket 204 are symmetrically arranged on the sides of the latch body 10 and the sleeve 20, respectively. A first limiting groove 102 is provided in the first socket 101, and a positioning groove 103 is provided at one end of the first limiting groove 102 in the first socket 101, and a second limiting groove 205 is provided in the second socket 204. The positioning pin assembly 50 includes an insertion rod 501, and a positioning block 504 is fixed on the surface of the insertion rod 501 near one end. The inner diameters of the first socket 101 and the second socket 204 are both adapted to the diameter of the insertion rod 501. The first limiting groove 102 and the positioning groove 103 are provided at one end of the first limiting groove 102. 03. The size of the second limiting groove 205 is compatible with the size of the positioning block 504. The two sleeves 20 are put on the two pin bodies 10, and then the positioning pin assembly 50 is taken to align the insertion rod 501 and the positioning block 504 with the second plug hole 204 and the second limiting groove 205 respectively. Then, the insertion rod 501 is inserted into the second plug hole 204 and the first plug hole 101 in turn, and the positioning block 504 slides into the first limiting groove 102 along the second limiting groove 205. Finally, the insertion rod 501 is rotated according to the trajectory of the positioning groove 103, and the positioning block 504 enters the positioning groove 103, which can prevent the insertion rod 501 from sliding out of the first plug hole 101 and the second plug hole 204, and the fixation between the pin body 10 and the sleeve 20 can be completed, that is, the fixation of the frame is realized.

[0026] The positioning pin assembly 50 also includes a disk 502, which is fixed to one end of the insertion rod 501, and a handle 503 is provided at one end of the disk 502, and the edge of the handle 503 is provided with a rounded corner. A receiving groove 202 is provided at the side of the sleeve 20 corresponding to the position of the second plug hole 204, and damping strips 203 are evenly provided on the inner side of the receiving groove 202. The setting of the damping strips 203 can increase the friction between the disk 502 and the receiving groove 202 to avoid accidental rotation of the insertion rod 501, thereby ensuring the stability of the locking mechanism.

[0027] In the present invention, a notch for inserting the latch body 10 is pre-set on the frame, and the size of the notch should match the size of the latch body 10. First, the lower end of the latch body 10 is inserted into the notch, and the latch body 10 can be fixed with bolts. Both ends of each safety belt body 40 are connected with a sleeve 20, and the safety belt body 40 is tied to the frame to be fixed. The length of the safety belt body 40 itself is adjustable (this is a mature technology in the prior art and is not repeated in the present invention). The two sleeves 20 are put on the two latch bodies 10, and then the positioning pin assembly 50 is taken to align the insertion rod 501 and the positioning block 504 with the second insertion hole 204 and the second limit groove 205 respectively, and then the insertion rod 501 is inserted into the second insertion hole 204 and the second limit groove 205 in sequence. The second plug hole 204 and the first plug hole 101 are inserted, and the positioning block 504 slides into the first limiting groove 102 along the second limiting groove 205. When one end of the plug rod 501 reaches the closed end of the first plug hole 101, the disc 502 just completely enters the receiving groove 202. Finally, the plug rod 501 is rotated according to the trajectory of the positioning groove 103, and the positioning block 504 enters the positioning groove 103, which can prevent the plug rod 501 from sliding out of the first plug hole 101 and the second plug hole 204, and the fixing between the bolt body 10 and the sleeve 20 is completed, that is, the fixing of the frame is realized. The setting of the damping strip 203 can increase the friction between the disc 502 and the receiving groove 202, and prevent the plug rod 501 from accidentally rotating, thereby ensuring the stability of the locking mechanism;

[0028] When the safety belt body 40 needs to be released, the user only needs to hold the handle 503 and rotate the insertion rod 501 to make the positioning block 504 slide out of the positioning groove 103 , and then take out the positioning pin assembly 50 , so that the sleeve 20 can be removed from the pin body 10 .

[0029] The above description 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.
