Abstract
Description
Technical Field
[0001] The utility model belongs to the field of hoisting slings, and particularly relates to an adjustable sling. Background Art
[0002] A sling is a tool for hoisting and transporting heavy objects. The overall structure of the sling includes a rope or belt body that determines the load-bearing capacity and elasticity, end rings or joints for connecting hoisting equipment, hoisting accessories, and possibly protection for enhancing wear resistance and preventing damage to ensure the safety and reliability of the sling. When selecting a sling, the load capacity, working environment, and usage frequency need to be considered to ensure safety and efficiency.

A clamping seat 223 is fixedly arranged at one end of the adjusting seat 221. A clamping plate 224 is arranged on one side of the clamping seat 223. The clamping plate 224 and the clamping seat 223 are connected into a whole by a bolt and nut 225.
[0021] In an embodiment of the present utility model, the length of the cable belt 21 can be adjusted through the arranged adjusting mechanism 22. Based on the extrusion friction between the cable belts 21, self-locking can be achieved. In cooperation with the arranged clamping seat 223 and clamping plate 224, the cable belt 21 can be further fixedly clamped through the arranged bolt and nut 225 to prevent loosening. Through the detachable first pin 122 and second pin 222, it is convenient to disassemble and replace the cable belt 21. At the same time, based on its detachable design, a conventional fixed-length cable belt 21 can also be replaced. The integrally cast design of the connector 1 improves the overall strength and has a longer service life.
[0022] In an example of the present utility model, during use, first loosen the clamping seat 223 and the clamping plate 224 by the provided bolt and nut 225 to leave an appropriate space, remove the first pin buckle 125 and the second pin buckle 228, pull out the first pin 122 and the second pin 222, fix one side of the end loop 211 with a ring at one end in the fixing cavity 126, pass the first pin 122 through the end loop 211 and fix it with the first pin buckle 125. The cable tie 21 passes through the inner cavity of the adjusting seat 221 and the gap between the clamping seat 223 and the clamping plate 224, place the middle part of the cable tie 21 in the other fixing cavity 126, and the first pin 122 on the other side restricts the cable tie 21 in the fixing cavity 126 and fixes it with the first pin buckle 125. The cable tie 21 winds back from the fixing cavity 126 and places the end loop 211 at the other end in the inner cavity of the adjusting seat 221, then pass the second pin 222 through the end loop 211 and fix it with the second pin buckle 228. Move the adjusting mechanism 22 to adjust the distance between the joints 1 to a suitable position, and then clamp the cable tie 21 with the bolt and nut 225, the clamping seat 223 and the clamping plate 224.
[0023] As Figure 1 and Figure 3 shown, as a preferred embodiment of the present utility model, the end loop 11 is in a horseshoe shape, and the end loop 11 and the fixing mechanism 12 are integrally cast. The fixing seat 121 is in a block structure, a fixing cavity 126 is fixedly arranged inside the fixing seat 121, and through holes with a diameter adapted to the first pin 122 are fixedly arranged at both ends of the fixing seat 121 corresponding to the position of the first pin 122.
[0024] Furthermore, the first pin hole 124 radially penetrates the first pin 122, and the cross-sectional dimension of the first pin buckle 125 is adapted to the inner diameter of the first pin hole 124.
[0025] In an example of the present utility model, through the design of integrally casting the joint 1, the overall strength is improved, and it has a longer service life. Through the provided first pin hole 124 and the first pin buckle 125, in cooperation with the provided first pin head 123, it is convenient to fix and limit the first pin 122, facilitate the disassembly and installation of the first pin 122, and further facilitate the disassembly, installation and replacement of the cable tie 21.
[0026] As Figure 2As shown, as a preferred embodiment of the present utility model, through holes adapted to the diameter of the second pin 222 are fixedly provided at both ends of the adjusting seat 221 corresponding to the positions of the second pins 222. One end of the second pin 222 is fixedly provided with a second nail head 226, the other end of the second pin 222 is fixedly provided with a second pin hole 227, and a second pin buckle 228 is inserted into the second pin hole 227. A cavity is fixedly provided inside the adjusting seat 221, and fillets are provided at the contact positions between the cavity inside the adjusting seat 221 and the cable tie 21. Both the clamping seat 223 and the clamping plate 224 are provided in a plate-like structure, and the clamping seat 223 and the adjusting seat 221 are integrally formed.
[0027] In an example of the present utility model, through the provided second pin hole 227 and second pin buckle 228, and in cooperation with the provided second nail head 226, it is convenient to fix and limit the second pin 222, facilitate the disassembly and installation of the second pin 222, and further facilitate the disassembly, installation and replacement of the cable tie 21. By providing fillets at the contact positions between the cavity inside the adjusting seat 221 and the cable tie 21, the friction of the edges and corners of the adjusting seat 221 against the cable tie 21 is reduced, preventing the cable tie 21 from being damaged by friction and causing a hoisting accident, and reducing potential safety hazards.
[0028] As Figures 1 to 3 shown, as a preferred embodiment of the present utility model, through holes adapted to the bolt nut 225 are fixedly provided at the positions of the clamping seat 223 and the clamping plate 224 corresponding to the bolt nut 225. Cable loops 211 are provided at both ends of the cable tie 21. The cable loop 211 at one end of the cable tie 21 is sleeved outside one side of the first pin 122. The cable tie 21 passes through the adjusting mechanism 22, winds back from the other side of the first pin 122, and the cable loop 211 at the other end is sleeved outside the second pin 222.
[0029] In an example of the present utility model, the length of the cable tie 21 can be adjusted through the provided adjusting mechanism 22. Based on the extrusion friction between the cable ties 21, it can be self-locked. In cooperation with the provided clamping seat 223 and clamping plate 224, the cable tie 21 can be further fixed and clamped through the provided bolt nut 225 to prevent loosening.
