Description

Technical Field

[0001] This utility model belongs to the technical field of shoulder strap protection pads, specifically relating to a backpack pressure reliever for relieving shoulder pressure. Background Technology

[0002] With the fast pace of modern life, the weight of backpacks people carry daily is gradually increasing. Carrying a heavy backpack for a long time often leads to shoulder discomfort or even injury. To address this, a variety of shoulder strap pads are now available on the market. Although they come in various forms, the basic structure consists of a large, thick, soft, and deformable pad filled with cushioning material. Velcro fasteners are sewn onto both sides of the pad, which is then attached to the shoulder strap to provide cushioning between the strap and the user's shoulder.

[0003] Because there are no standardized dimensions for backpack shoulder strap widths on the market, manufacturers often design shoulder strap pads to be wider to improve their versatility. While this allows the pads to fit over various shoulder strap widths, when there's a significant difference in width between the strap and the pad, the Velcro closure on the pad doesn't provide adequate anti-slip protection. Its primary function is to prevent the pad from detaching from the strap, not to prevent the strap from sliding inside the pad. When the strap slides inside the pad, the backpack wobbles against the wearer's body, significantly reducing carrying comfort. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a backpack comforter for relieving shoulder pressure, solving the problem that existing shoulder strap pads cannot prevent the shoulder straps from sliding inside the pads during use, causing the backpack to sway on the wearer's body and greatly reducing carrying comfort.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a backpack pressure reliever for relieving shoulder pressure, comprising a shoulder strap cushioning pad body, wherein a first strap and a second strap are sewn onto the left and right sides of the shoulder strap cushioning pad body respectively; a male Velcro face is sewn onto the front of the first strap; a male Velcro face and a female Velcro face are sewn onto the front and back of the second strap respectively; both ends of a positioning strap are sewn onto the front of the shoulder strap cushioning pad body; two positioning buckles are clamped on the positioning strap; each positioning buckle includes a U-shaped elastic clip; both ends of the U-shaped elastic clip are respectively formed with a secondary locking groove and a locking block; the locking groove is adapted to lock the locking block.

[0006] The beneficial effects of this utility model are as follows: by adjusting the position of the positioning buckle on the positioning strap, the positioning buckle is supported on both sides of the shoulder strap, ensuring that the shoulder strap will not slide left and right inside the shoulder strap cushioning pad body, effectively improving the safety and comfort of carrying.

[0007] To further improve the positioning effect of the positioning buckle on the shoulder strap;

[0008] As a further improvement to the above technical solution: the positioning strap is set on the main body of the shoulder strap cushioning pad between the first strap and the second strap.

[0009] The beneficial effects of this improvement are: after the first and second straps are attached to each other with Velcro, the shoulder strap is stably pressed between the two positioning buckles, preventing the shoulder strap from sliding out and moving from above the positioning buckles.

[0010] To further improve the positioning effect of the positioning buckle on the shoulder strap;

[0011] As a further improvement to the above technical solution: the top surface of the U-shaped elastic clip is bonded with a secondary hook and loop fastener female surface, which is adapted to bond with the hook and loop fastener male surface.

[0012] The beneficial effects of this improvement are as follows: when the second strap bend cover is installed on the upper side of the positioning buckle, the male side of the Velcro adheres to the female side of the secondary Velcro, so that the two positioning buckles, the positioning strap, and the second strap form an enclosed frame structure, further preventing the shoulder strap from sliding out and moving from the top of the positioning buckle.

[0013] To facilitate the easy disengagement of the latching block from the latching slot;

[0014] As a further improvement to the above technical solution: a protrusion is connected to the side of the snap-fit ​​block facing away from the snap-fit ​​groove, and a curved protrusion is formed on the U-shaped elastic clip on one side of the snap-fit ​​groove.

[0015] The beneficial effect of this improvement is that the operator can hold the protrusion and move the locking block to the outside of the locking groove with less effort, thereby disengaging the locking block from the locking groove.

[0016] To improve the locking effect of the U-shaped elastic clip on the positioning strip;

[0017] As a further improvement to the above technical solution: the inner side of the U-shaped elastic clip is formed with anti-slip teeth.

[0018] The beneficial effects of this improvement are: the anti-slip teeth can increase the friction between the U-shaped elastic clip and the positioning band, thereby improving the locking effect of the U-shaped elastic clip on the positioning band.

[0019] To improve the cushioning comfort of the shoulder strap padding body;

[0020] As a further improvement to the above technical solution: the main body of the shoulder strap cushioning pad is composed of an inner layer, an outer layer and a cushioning air cushion. The number of cushioning air cushions is multiple, and they are equally spaced between the inner layer and the outer layer and are sewn together with the inner layer and the outer layer.

[0021] The beneficial effects of this improvement are: the cushioning air cushion effectively absorbs energy and reduces the pressure of the shoulder strap on the shoulder.

[0022] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0027] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0028] Example 1:

[0029] like Figure 1—3 shows a backpack pressure reliever for alleviating shoulder pressure, comprising a shoulder strap cushioning pad body 1. A first strap 2 and a second strap 3 are sewn onto the left and right sides of the shoulder strap cushioning pad body 1, respectively. A male Velcro face 4 is sewn onto the front of the first strap 2. A male Velcro face 4 and a female Velcro face 5 are sewn onto the front and back of the second strap 3, respectively. The two ends of a positioning strap 6 are sewn onto the front of the shoulder strap cushioning pad body 1. Two positioning buckles 7 are clamped onto the positioning strap 6. Each positioning buckle 7 includes a U-shaped elastic clip 71, with a secondary locking groove 74 and a locking mechanism formed at both ends of the U-shaped elastic clip 71. Block 73, the snap-fit ​​groove 74 is adapted to snap-fit ​​block 73, by adjusting the position of the positioning buckle 7 on the positioning strap 6 so that the positioning buckle 7 is supported on both sides of the shoulder strap, ensuring that the shoulder strap will not slide left and right inside the shoulder strap cushioning pad body 1, effectively improving the safety and comfort of carrying. The positioning strap 6 is set on the shoulder strap cushioning pad body 1 between the first strap 2 and the second strap 3. After the first strap 2 and the second strap 3 are glued to each other by Velcro, the shoulder strap is stably pressed between the two positioning buckles 7, preventing the shoulder strap from sliding out from above the positioning buckles 7. The top surface of the U-shaped elastic clip 71 is glued with a secondary Velcro female surface 72. The female side 72 of the secondary hook and loop fastener is adapted to adhere to the male side 4 of the hook and loop fastener. When the second strap 3 is bent and covered on the upper side of the positioning buckle 7, the male side 4 of the hook and loop fastener adheres to the female side 72 of the secondary hook and loop fastener, so that the two positioning buckles 7, the positioning strap 6, and the second strap 3 form an enclosing frame structure, further preventing the shoulder strap from slipping out from above the positioning buckle 7. The side of the snap-fit ​​block 73 facing away from the snap-fit ​​groove 74 is connected to a protrusion 75. The U-shaped elastic clip 71 on one side of the snap-fit ​​groove 74 is formed with a curved protrusion 77. The operator can hold the protrusion 75 to move the snap-fit ​​block 73 to the outside of the snap-fit ​​groove 74 with ease, thereby making the snap-fit ​​block 73 move outward. 3. Disengage from the snap-fit ​​groove 74. The inner side of the U-shaped elastic clip 71 is formed with anti-slip teeth 76. The anti-slip teeth 76 can increase the friction between the U-shaped elastic clip 71 and the positioning band 6, thereby improving the locking effect of the U-shaped elastic clip 71 on the positioning band 6. The shoulder strap cushioning pad body 1 is composed of an inner layer 11, an outer layer 12 and a cushioning air cushion 13. There are multiple cushioning air cushions 13, which are equally spaced between the inner layer 11 and the outer layer 12 and are sewn together with the inner layer 11 and the outer layer 12. The cushioning air cushions 13 play an effective role in cushioning and absorbing energy, reducing the pressure of the shoulder strap on the shoulder.

[0030] The working principle of this technical solution is as follows: When in use, place the shoulder strap cushioning pad 1 under the shoulder strap. At this time, the shoulder strap is located on the positioning strap 6. Adjust the position of the two loose positioning buckles 7 so that the two positioning buckles 7 press against the two sides of the shoulder strap. Then lock the position of the positioning buckles 7 and press the two ends of the U-shaped elastic clip 71 so that the snap block 73 slides along the curved protrusion 77 and snaps into the snap groove 74. Then bend the second strap 3 to cover the positioning strap 6 so that the male side 4 of the Velcro on the second strap 3 is bonded to the female side 72 of the secondary Velcro, further locking the position of the shoulder strap and effectively preventing the shoulder strap from sliding left and right inside the device. Finally, bend the first strap 2 so that the male side 4 of the Velcro on the first strap 2 is bonded to the female side 5 of the Velcro, and securely bind the device to the shoulder strap.
