[0029] like Figures 1 to 8 As shown, this utility model embodiment provides a backpack-type transport belt, including a back strap 100 and a strap 200.

[0030] Among them, the shoulder strap 100 is provided with two wearing openings 130 that can be worn on the shoulders of the human body, and the shoulder strap 100 is provided with two connection structures corresponding to the wearing openings 130. Specifically, the connection structure includes an adjusting buckle 300, a connecting buckle 400, and an elastic element 500. The adjusting buckle 300 and the connecting buckle 400 are arranged vertically at intervals. In this embodiment, the adjusting buckle 300 is preferably arranged above the connecting buckle 400.

[0031] Furthermore, the adjusting buckle 300 has a support wall 330 and a clamping member 600 corresponding to the support wall 330 is rotatably disposed therein. The clamping member 600 has a release position and a clamping position. When the clamping member 600 is in the release position, a clamping opening 700 is formed between the clamping member 600 and the support wall 330. The strap 200 has a connecting end 210 and an inserting end 220. The connecting end 210 is connected to the connecting buckle 400, and the inserting end 220 passes through the clamping opening 700 to form a space for binding items.

[0032] Furthermore, the elastic element 500 is used to drive the clamping element 600 to rotate from the release position to the clamping position, so that the clamping element 600 clamps the strap 200 with the support wall 330.

[0033] Furthermore, the clamp 600 is configured such that when the insertion end 220 is pulled along the direction in which the strap 200 passes through the clamp opening 700, the clamp 600 can be rotated from the clamping position to the releasing position, so as to allow the strap 200 to slide and thus tighten the item.

[0034] When using this product, for heavier items, the operator can first connect the connecting end 210 of the strap 200 to the connecting buckle 400, then wrap the strap 200 around the item. Next, by moving the clamp 600 to the release position, the clamp 600 is disengaged from the support wall 330, forming a clamp 700. The insertion end 220 of the strap 200 is then passed through the clamp 700 from below. After the operator releases their grip, the elastic element 500 drives the clamp 600 to rotate to the clamping position, clamping the strap 200. The operator can then put on the carrying strap 100 and pull the insertion end 220 to tighten the space as needed, thus securing the item. This simple operation ensures that the item is not easily loosened during handling, improving safety. It also allows for quick tightening or adjustment of the strap 200, facilitating flexible adjustment of the binding space according to the item's size, adapting to different load requirements. The simple structure reduces the failure rate and facilitates maintenance.

[0035] In one embodiment, the support wall 330 is provided with a support surface 331 facing the clamping member 600. The support surface 331 is inclined upward. The clamping member 600 is provided with a clamping surface 610 corresponding to the support surface 331. The clamping surface 610 is inclined downward. When the clamping member 600 is in the clamping position, the clamping surface 610 abuts against the support surface 331. When the clamping member 600 is in the release position, the clamping surface 610 is disengaged from the support surface 331, and a clamping opening 700 is formed between them. The support surface 331 and the clamping surface 610 generate a self-locking effect, becoming tighter and tighter as they are pulled, greatly improving the resistance to pull-out.

[0036] In one embodiment, a plurality of serrations 620 are formed on the clamping surface 610. The serrations 620 can increase the frictional resistance between the clamping surface 610 and the strap 200, preventing the strap 200 from slipping during vibration. The tips of the serrations 620 are provided with arc-shaped rounded corners 621. The arc-shaped rounded corners 621 can avoid cutting the surface of the strap 200, extend the service life of the strap 200, and improve the smoothness when pulling the insertion end 220 to adjust the strap 200, thereby improving the user experience.

[0037] In one embodiment, the support surface 331 is provided with stripes 332 arranged along the axial direction of the clamping member 600. Multiple stripes 332 are arranged at intervals along the inclined direction of the support surface 331. The serrations 620 can abut against the stripes 332. The stripes 332 have an anti-slip function to improve the clamping efficiency of the clamping member 600 and the support wall.

[0038] In some specific embodiments, the adjusting buckle 300 includes two side walls 310, a connecting wall 320, and a supporting wall 330. The supporting wall 330 is disposed at both ends of the side walls 310 and is connected to the two side walls 310 respectively. A partition wall 340 is provided between the supporting wall 330 and the connecting wall 320. The two ends of the partition wall 340 are connected to the two side walls 310 respectively. The two side walls 310, the connecting wall 320, the supporting wall 330, and the partition wall 340 are integrally formed, and the structure is stable.

[0039] An installation opening 333 is formed between the partition wall 340 and the support wall 330. A clamping member 600 is provided at the installation opening 333. A connector 334 is provided at the installation opening 333. The connector 334 passes through the two side walls 310 and the clamping member 600. The clamping member 600 and the connector 334 are rotatably connected. Specifically, the connector 334 is preferably a rivet. The clamping member 600 is provided with a through hole that is coaxial with and adapted to the rivet. The rivet passes through the through hole and is rotatably connected to the through hole.

[0040] In some specific embodiments, the shoulder strap 100 includes a body 110 and two shoulder straps 120. The upper end of the body 110 is provided with two first connecting pieces 111 corresponding to the human shoulder, and the lower end is provided with a second connecting piece 112 corresponding to the first connecting piece 111. The two ends of the two shoulder straps 120 are respectively sewn to the corresponding first connecting piece 111 and second connecting piece 112 to form two wearing openings 130. Further, a first connecting opening 341 is formed between the partition wall 340 and the connecting wall 320. A connecting strap 342 is threaded through the first connecting opening 341. The two ends of the connecting strap 342 are sewn onto the first connecting piece 111. The connecting strap 342 is used to install the adjusting buckle 300 and allows the adjusting buckle 300 to move freely for easy operation by the staff.

[0041] Furthermore, the connecting buckle 400 is provided with a second connecting port 410, through which the shoulder strap 120 passes. The lower end of the connecting buckle 400 is also provided with a hook part 420. The connecting end 210 of the strap 200 has a hanging opening 221 that matches the hook part 420. The hanging opening 221 is hooked onto the hook part 420. The operation is simple. The hooking design of the hanging opening 221 and the hook part 420 can quickly detach and install the strap 200, which is convenient for subsequent cleaning or replacement of the strap 200.

[0042] In one embodiment, the upper end of the clamping member 600 is provided with an operating part 630 for applying force with a finger. The operating part 630 extends upward and is inclined in a direction away from the support wall 330. The operating part 630 facilitates the operator to apply force to operate the clamping member 600 to unlock it, thereby improving work efficiency.

[0043] In one embodiment, the operating part 630 has an upward-facing groove 631 for inserting a finger. The groove 631 provides a fixed position for the finger, making unlocking easier and less prone to slipping.

[0044] In one embodiment, the elastic element 500 is a torsion spring, and the clamping member 600 has a cutout 640 in the middle of the side near the partition wall 340, exposing part of the connecting member 334. The torsion spring is located at the cutout 640 and is sleeved on the connecting member 334. The torsion spring has two connecting arms 510, one of which abuts against the side of the operating part 630 facing downwards, and the other connecting arm 510 abuts against the partition wall 340. This enables the elastic element 500 to drive the clamping member 600 to rotate from the release position to the clamping position, and the structure is more compact, saving space.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
