[0030] Figure 1 Shown therein is a schematic diagram of the overall structure of a sling with an adjustable clamping length in an embodiment of the present disclosure. Figure 2 Shown therein is a schematic cross-sectional view of a sling with an adjustable clamping length in an embodiment of the present disclosure. In Figure 1 and Figure 2In the example, the sling with adjustable clamping length includes a support rod 10, two clamping members 20, and at least one suspension member 30. A plurality of adjusting portions 11 are formed at intervals along the length direction on the outer surface of the support rod 10. The two clamping members 20 are arranged on the support rod 10; at least one of the clamping members 20 is slidably combined with the support rod 10, and a fixing portion 21 that is snap-fitted to at least one of the adjusting portions 11 is provided on at least one of the clamping members 20. The at least one suspension member 30 is arranged on the support rod 10.
[0031] In the above arrangement, by the cooperation of the adjusting portion 11 and the fixing portion 21, the position of at least one of the clamping members 20 on the support rod 10 is moved to adjust the distance between the two clamping members 20, so that the sling can clamp battery packs of different lengths, improving the applicability of the sling. Secondly, due to the arrangement of the support rod 10 and the suspension member 30, the operator can move by lifting the support rod 10 or can suspend by the cooperation of the crane hook and the suspension member 30, improving the functionality of the sling.
[0032] In Figure 1 and Figure 2 the example, the clamping member 20 includes a fastening end 22 and a clamping end 23. The fastening end 22 is slidably combined with the support rod 10, and the fixing portion 21 is connected to the fastening end 22. The clamping end 23 is connected to the fastening end 22.
[0033] In Figure 1 and Figure 2 the example, the suspension member 30 is arranged on the support rod 10 with adjustable position. Exemplarily, the suspension member 30 includes a sliding block 31, a fastening block 32, and a suspension ring 33; the sliding block 31 is slidably combined with the support rod 10, the fastening block 32 is screwed to the sliding block 31 and one end can pass through the fastening block 32 and abut against the outer surface of the support rod 10 to form a fixation, and the suspension ring 33 is connected to the top of the fastening block 32. Those skilled in the art can understand that when the position of the suspension member 30 needs to be adjusted, the operator relatively rotates the sliding block 31 and the fastening block 32 so that the fastening block 32 no longer abuts against the support rod 10, and after the sliding block 31 moves to the designated position, the fastening block 32 can be made to abut against the support rod 10 again.
[0034] In another embodiment, the way of adjusting the position of the suspension member 30 can also be the same as the way of adjusting the position of the clamping member 20. In this way, the suspension member can only include a sliding block and a suspension ring, the sliding block is slidably combined with the support rod, the suspension ring is directly connected to the sliding block, and a fixing portion that is snap-fitted to one of the adjusting portions is provided on the sliding block.
[0035] Exemplarily, the suspension member 30 is implemented as one. The one suspension member 30 is located at a position between the two clamping members 20. Therefore, when the distance between the two clamping members 20 changes, the operator can adjust the position of the suspension member 30 accordingly, so that the suspension member 30 remains in the middle position between the two clamping members 20. Those skilled in the art can understand that when the operator cooperates with the suspension member 30 through a crane hook for suspension, the suspension member 30 in the middle position between the two clamping members 20 can maintain the stability of the entire lifting tool in the air, thereby avoiding the situation that the lifting tool loses balance due to unreasonable lifting positions.
[0036] In other embodiments, the suspension member 30 is implemented as a pair, and the pair of suspension members 30 are located between the two clamping members 20 on the support rod 10.
[0037] Alternatively, the suspension member 30 is implemented as a pair, and the pair of clamping members 20 are located between the two suspension members 30 on the support rod 10. In this way, the stability of the entire lifting tool in the air can be further improved by suspending the two suspension members 30.
[0038] Exemplarily, both ends of the support rod 10 are implemented as lifting operation parts 12. Further exemplarily, the lifting operation part 12 is provided with an insulating member 121. Those skilled in the art can understand that in order to improve the overall strength of the lifting tool, the support rod 10 and the clamping members 20 are usually implemented to be made of stainless steel or aluminum alloy. When the item to be clamped is a battery pack, the insulating member 121 can prevent the operator from getting an electric shock.
[0039] In Figure 2 the example, both of the two clamping members 20 are slidably coupled to the support rod 10; each clamping member 20 respectively has a fixing part 21 that is snap-fitted to the adjusting part 11. In this way, the operator can adjust the distance between the two clamping members 20 by respectively moving the two clamping members 20. Especially when two operators move the battery pack clamped by the lifting tool by lifting the support rod 10, the distance between the two clamping members 20 can be quickly adjusted by the above method. At the same time, because the positions of the two clamping members 20 can both be adjusted, the clamping space between the two clamping members 20 can be located in the middle position of the entire support rod 10, so that the gravity received by the two operators lifting the lifting tool is more uniform, and further avoiding the situation that the entire lifting tool shows uneven weight distribution.
[0040] Exemplarily, scale lines (not shown) are provided on the outer surface of the support rod 10 at intervals along its length direction. To facilitate the operator to adjust the distance between the two clamping members 20 and clamp battery packs of different lengths.
[0041] In another embodiment, one of the clamping members is fixedly connected to the support rod and is close to one of the lifting operation portions, and the other clamping member is slidably engaged with the support rod. In this way, the other clamping member can be slid to the other lifting operation portion of the support rod, so as to increase the adjustment range of the two clamping members.
[0042] In Figure 2 the example, the adjusting portion 11 is implemented as a circular adjusting hole. The fixing portion 21 is connected to the clamping member 20 in a threaded connection manner. In another embodiment, the adjusting hole is a rectangular hole, and the fixing portion 21 is connected to the clamping member 20 in a sliding connection manner.
[0043] In Figure 1 and Figure 2 the example, the clamping member 20 is slidably engaged with the support rod 10 in a rotationally restricted manner. Exemplarily, a first guiding groove 101 extending along the length direction of the support rod 10 is formed on the support rod 10, and the first guiding groove 101 completely penetrates the support rod 10 in the radial direction of the support rod 10. A first guiding block 24 inserted into the first guiding groove 101 is provided on the clamping member 20. In this way, when the clamping member 20 moves along the support rod 10, the first guiding block 24 moves in the first guiding groove 101, and at the same time, the rotation of the clamping member 20 on the support rod 10 is avoided. Further exemplarily, the diameter of the first guiding block 24 is adapted to the first guiding groove 101 to further improve the effect of restricting the rotation of the clamping member 20.
[0044] Exemplarily, the distance that the clamping member 20 can move on the support rod 10 is the same as the length of the first guiding groove 101. One or more of the adjusting portions 11 are formed on the outer surface of the support rod 10 within the distance that the clamping member 20 moves.
[0045] Figure 3 Shown is a partial cross-sectional schematic view of another embodiment in which the rotation of the clamping member 20 is restricted in the embodiment of the present disclosure. In Figure 3In the example, the clamping member 20 is slidably coupled to the support rod 10 in a rotationally restricted manner. Exemplarily, the support rod 10 is implemented as a circular rod. A second guiding groove 102 is recessed inward along the length direction at the bottom end of the support rod 10. A first guiding block 24 that is slidably coupled within the second guiding groove 102 is provided on the wall surface of the clamping member 20 that abuts against the support rod 10. Those skilled in the art can understand that the cooperation between the second guiding groove 102 and the first guiding block 24 enables the clamping member 20 to only move along the length of the support rod 10 and prevents circumferential rotation of the clamping member 20 relative to the support rod 10. This ensures that the clamping positions of the two clamping members 20 on the object to be clamped do not change, thereby guaranteeing the clamping effect. Exemplarily, the implementation manners of the second guiding groove 102 and the second guiding block 25 can be interchanged, that is, the second guiding groove 102 is formed on the wall surface of the clamping member 20 that abuts against the support rod 10, and the second guiding block 25 protrudes from the outer surface of the support rod 10.
[0046] In other embodiments, the support rod 10 is implemented with a non-circular cross-section, such as rectangular or elliptical. In this way, the clamping member 20 can slide along the length direction of the support rod 10, and the clamping member 20 can be slidably coupled to the support rod 10 in a rotationally restricted manner.
[0047] In summary, an adjustable clamping length sling provided in an embodiment of the present disclosure includes: a support rod, on the outer surface of which a plurality of adjusting portions are formed at intervals along the length direction; two clamping members disposed on the support rod; at least one of the clamping members is slidably coupled to the support rod, and a fixing portion that is snap-fitted to at least one of the adjusting portions is provided on at least one of the clamping members; at least one suspension member is disposed on the support rod. In the above arrangement, the position of at least one of the clamping members on the support rod is adjusted by the cooperation between the adjusting portion and the fixing portion to adjust the distance between the two clamping members, so that the sling can clamp battery packs of different lengths, improving the applicability of the sling. Secondly, due to the provision of the support rod and the suspension member, the operator can move the support rod by lifting it or can perform suspension by cooperating the crane hook with the suspension member, improving the functionality of the adjustable clamping length sling.
[0048] The above embodiments merely illustrate the principles and effects of the present disclosure and are not used to limit the present disclosure. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present disclosure. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present disclosure should still be covered by the protection scope of the present disclosure.
