Description

Technical Field

[0001] The present application relates to the technical field of lifting belts, and in particular to a lifting belt with a locking device. Background Art

[0002] Lifting belts are generally made of high-strength polyester filaments, which have multiple advantages such as high strength, wear resistance, oxidation resistance, and UV resistance. At the same time, they are soft, non-conductive, and non-corrosive. They are widely used in various fields. Lifting belts are generally combined with end parts and locks to form a bundler, which is used for fixing functions during the transportation, movement, shipment, or storage of goods.

[0003] At present, the fastener includes a pulling shaft and a ratchet shaft, which are respectively arranged at two ends of the fastener. A lifting belt is fixedly connected to the pulling shaft. When bundling goods, one end of another lifting belt passes through the ratchet shaft and overlaps with the lifting belt on the pulling shaft. At this time, the lifting belt is tightened by the fastener so that the goods can be tied tightly by the lifting belt.

[0004] With respect to the above-mentioned related technologies, the following defects are found: when the fastener pulls the lifting belt close to tie the goods tightly, during the transportation process, since one end of the other lifting belt passes through the ratchet shaft and overlaps with the lifting belt on the pulling shaft, the part of the other lifting belt passing through the ratchet shaft may fly due to the wind force generated during transportation. The part of the other lifting belt passing through the ratchet shaft generates other forces due to the wind force during the flying process, and this force may affect the stability of the fastener when tightening the lifting belt.

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The present application embodiment discloses a lifting belt with a locking device. Figure 1 A lifting belt with a locking device comprises a locking device 1, a lifting belt 2 and a fastening component 3. The lifting belt 2 is used to tie up the cargo through the locking device 1. The fastening component 3 is arranged on the lifting belt 2 to fix the lifting belt 2.

[0034] Reference Figure 1 The locking device 1 includes a fastener 11, a pulling member 12 and a ratchet shaft 13. The fastener 11 and the pulling member 12 are rotatably connected through the ratchet shaft 13. The end of the fastener 11 that is rotatably connected to the pulling member 12 through the ratchet shaft 13 is the right end of the fastener 11. A pulling shaft 111 is passed through and fixed to the left end of the fastener 11. The lifting belt 2 includes a first binding belt 21 and a second binding belt 22. One end of the first binding belt 21 is sleeved and fixed on the pulling shaft 111. The second binding belt 22 passes through the ratchet shaft 13 and overlaps with the first binding belt 21. The part where the second binding belt 22 overlaps with the first binding belt 21 is the overlapping part 221. The end where the first binding belt 21 overlaps with the overlapping part 221 is the upper end of the first binding belt 21, and the end where the overlapping part 221 overlaps with the first binding belt 21 is the lower end of the overlapping part 221.

[0035] Reference Figure 1 and Figure 2 The fastening assembly 3 is sleeved on the position where the first binding belt 21 and the overlapping portion 221 overlap. The fastening assembly 3 includes a fastening box 31, an extrusion plate 32 and a rotating screw 33. Through holes 311 are opened at the opposite front and rear end side walls of the fastening box 31. The left end of the first binding belt 21 and the left end of the overlapping portion 221 are both inserted into the fastening box 31 through the through holes 311. The size of the through hole 311 is larger than the size of the first binding belt 21 and the overlapping portion 221 after overlapping, and the lower end surface of the first binding belt 21 abuts against the inner lower end surface of the fastening box 31. In order to increase the friction force when the first binding belt 21 abuts against the fastening box 31, a plurality of equidistantly distributed second extrusion protrusions 312 are integrally formed at the inner lower end surface of the fastening box 31.

[0036] Reference Figure 2 The cam 322 is a substantially parallel arrangement of the two cams 324, with the cam 324 being arranged on the cam 326 to move relative to the top of the cam 328. The cam 322 is a substantially parallel arrangement of the two cams 324, with the cam 326 being arranged on the cam 326 to move relative to the top of the cam 328.

[0037] Reference Figure 1 and Figure 2The lower end surface of the extrusion plate 32 moves downward in the slide groove 314 through the slider 321 to abut against the upper end surface of the overlapping portion 221 and extrudes the overlapping portion 221. In order to generate friction when the extrusion plate 32 extrudes the overlapping portion 221, a plurality of equidistantly distributed first extrusion protrusions 323 are integrally formed at the lower end surface of the extrusion plate 32. In order to prevent the extrusion plate 32 from escaping from the fastening box 31 when the extrusion plate 32 is not extruding the overlapping portion 221, a cover plate 315 is welded at the upper end surface of the fastening box 31 where the opening 313 is provided.

[0038] Reference Figure 1 and Figure 2 A threaded hole 3151 is provided at the center position of the cover plate 315, and the rotating screw 33 is threadedly connected to the threaded hole 3151 and abuts against the upper end surface of the extrusion plate 32. In this embodiment, the rotating screw 33 is rotated clockwise, and the rotating screw 33 can press the overlapping portion 221 downward against the extrusion plate 32, so that the overlapping portion 221 is tightly overlapped and fixed with the first binding belt 21.

[0039] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In order to enable the rotating screw 33 to bring the extrusion plate 32 upward to release the extrusion of the overlapping portion 221, a positioning groove 324 is provided at the upper end surface of the extrusion plate 32 aligned with the rotating screw 33, a snap ring groove 3241 is provided at the groove wall of the positioning groove 324, and a positioning column 331 is integrally formed at the lower end surface of the rotating screw 33. The positioning column 331 cooperates with the positioning groove 324 to pre-position the rotating screw 33 on the extrusion plate 32, and a snap ring block 3311 that cooperates with the snap ring groove 3241 is integrally formed at the outer side wall of the positioning column 331, and after the snap ring block 3311 is snapped with the snap ring groove 3241, a gap is left between the snap ring block 3311 and the groove wall of the snap ring groove 3241.

[0040] The implementation principle of the lifting belt with a locking device in the embodiment of the present application is as follows: the left end of the first binding belt 21 and the left end of the overlapping portion 221 are both inserted through the through hole 311, and then the rotating screw 33 is rotated clockwise, and the rotating screw 33 and the threaded hole 3151 are matched to move downward, so that the rotating screw 33 presses the overlapping portion 221 against the extrusion plate 32, and the clockwise rotation of the rotating screw 33 can be stopped when the overlapping portion 221 is squeezed to the point that it is difficult to escape from the fastening box 31;

[0041] When the rotating screw 33 is rotated counterclockwise, the rotating screw 33 cooperates with the threaded hole 3151 to move upward, and with the cooperation of the snap ring block 3311 and the snap ring groove 3241, the rotating screw 33 moves upward with the extrusion plate 32, so that the extrusion plate 32 is not squeezed with the overlapping part 221, and the overlapping part 221 can be detached from the fastening box 31.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
