[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model discloses a portable seat belt attachment device for multiple application scenarios.

[0026] This utility model provides, for example Figure 1-3 The portable seat belt attachment device for multiple scenarios shown includes a shaft housing 1 and clamping arms 2. Both ends of the shaft housing 1 are fitted with bearing covers 3. Bearings 4 are fixedly installed on the inner wall of the bearing covers 3. A spiral shaft 5 is provided between the two bearings 4 for common rotation. The spiral shaft 5 is a bidirectional spiral shaft with opposite thread directions at both ends of the shaft wall. The two ends of the spiral shaft 5 pass through the two bearing covers 3 respectively. The two clamping arms 2 are threaded onto the outer ends of the spiral shaft 5 respectively. The side of the shaft housing 1 is provided with a sliding groove 6 for sliding with the clamping arms 2. Clamping blocks 7 are fixedly installed at the close ends of the two clamping arms 2. Anti-slip pads 11 are fixedly installed on the close sides of the two clamping blocks 7.

[0027] The outer wall of the shaft housing 1 is provided with a connecting handle 8. Both ends of the connecting handle 8 are provided with hanging rope holes 9, and the middle of the connecting handle 8 is provided with a handle hole 10.

[0028] To facilitate the disassembly and maintenance of internal components of the device, such as Figure 2-3 As shown, the sides of both bearing caps 3 are threaded with mounting bolts 12, and both ends of the outer wall of the shaft housing 1 are threaded holes 13 for the mounting bolts 12 to be inserted. The outer wall of the shaft housing 1 is provided with a positioning groove 14, and the connecting handle 8 is inserted into the positioning groove 14. A fixing bolt 15 is threaded between the inner wall of the handle hole 10 and the positioning groove 14.

[0029] Working principle: When using this portable safety belt attachment device, first place the device on the structure to be clamped (such as a photovoltaic module bracket), hold the handle hole 10, and rotate the spiral shaft 5. Since the spiral shaft 5 is a double spiral and the threads at both ends are opposite, the two clamping arms 2 will slide towards each other along the sliding groove 6 on the side of the shaft housing 1 under the drive of the spiral shaft 5, so that the clamping block 7 clamps the structure. The anti-slip pad 11 on the clamping block 7 can increase the friction and prevent the device from sliding. After the clamping block 7 has firmly clamped the structure, pass the safety belt rope through the rope holes 9 at both ends of the handle 8 to complete the attachment of the safety belt.

[0030] When it is necessary to disassemble the device, rotate the spiral shaft 5 in the opposite direction to open the clamping arm 2, loosen the clamping on the structure, and then use the mounting bolt 12, fixing bolt 15, etc. to inspect or disassemble the internal components of the device.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
