Description

Technical Field

[0001] This utility model relates to the field of backpack technology, specifically to a multifunctional backpack shoulder support. Background Technology

[0002] A schoolbag is a backpack used to carry books, documents, and other items. It is usually made of durable materials such as canvas or nylon and has multiple pockets and compartments to organize and separate different items. Schoolbags are typically essential items for students carrying books and school supplies to school, and are also widely used in daily life and travel.

[0003] Backpacks are tools for carrying items. They have two straps fixed on one side. By putting the two straps over the shoulders, they are easy to carry. Usually, one end of the straps has an adjustment device so that the length of the straps can be adjusted to suit people of different heights. The shoulder pads are located above the straps and are part of the straps. They usually fit snugly against the shoulders and provide additional cushioning and protection.

[0004] In existing backpacks, the shoulder support is usually fixed above the shoulder strap. Although the backpack shoulder strap can be adjusted to accommodate people of different heights, the adjustment will change the position of the shoulder support and the shoulder, making it difficult for the shoulder support to function. At the same time, when the height difference is too large, it is difficult to adjust the shoulder strap. Utility Model Content

[0005] (1) Technical problems solved

[0006] The technical problem this invention aims to solve is that although the backpack shoulder straps can be adjusted to accommodate people of different heights, the adjustment will change the position of the shoulder support and the shoulder. At the same time, when the height difference is too large, it is difficult to adjust the shoulder straps.

[0007] (2) Technical solution

[0008] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a multifunctional backpack shoulder support, including a backpack, one side of which is provided with corresponding sliding grooves on both sides, a slider is slidably connected in the sliding groove, a first shoulder strap is fixedly connected to the slider, a second shoulder strap is provided at the bottom of one side of the backpack, the first shoulder strap and the second shoulder strap are connected by a telescopic buckle, a shoulder support is fixedly connected to the first shoulder strap, the first shoulder strap and the shoulder support are fixedly connected by Velcro, one end of the slider is provided with a slot, a locking block is movably inserted into the slot, a spring is fixedly connected between the locking block and the slot, the backpack is provided with at least one insertion hole that cooperates with the locking block, a push block is movably inserted into the insertion hole, and a pressing plate is fixedly connected to one end of the push block.

[0009] As an improvement, a limiting plate is fixedly connected to one end of the slider, and a limiting groove that cooperates with the limiting plate is provided in the sliding groove.

[0010] As an improvement, the shoulder support consists of a sweat-absorbing layer, a sponge pad, and a breathable foam pad.

[0011] As an improvement, one side of the shoulder support is hooked, and the first shoulder strap is fleece-like.

[0012] As an improvement, limit blocks are fixedly connected to both sides of the card block, and the slider has a groove in the slot that cooperates with the limit blocks.

[0013] As an improvement, the side of the backpack located on the slide is a hard surface and made of plastic.

[0014] As an improvement, a sleeve is fitted onto the first shoulder strap, and the sleeve is made of a flexible material.

[0015] (3) Beneficial effects

[0016] The advantages of this utility model compared with the prior art are as follows:

[0017] By pushing the press plate, the push block pushes the locking block into the slot. Then, the slider is slid to the appropriate position, and the spring pushes the locking block into the insertion hole, thereby shortening the distance between the first and second shoulder straps and increasing the adjustment range. The shoulder support is connected to the first shoulder strap via Velcro, which allows the position of the shoulder support to be changed to accommodate people of different heights.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1 to 2 As shown, a multifunctional backpack shoulder support includes a backpack 1. One side of the backpack 1 has corresponding sliding grooves 2 arranged on both sides. The side of the backpack 1 facing the sliding grooves 2 is a hard surface made of plastic. A slider 3 is slidably connected within the sliding grooves 2. One end of the slider 3 is fixedly connected to a limiting plate 13. The sliding groove 2 has a limiting groove that cooperates with the limiting plate 13. A first shoulder strap 4 is fixedly connected to the slider 3. A sleeve 18, made of flexible material, is fitted onto the first shoulder strap 4. A second shoulder strap 5 is located at the bottom of one side of the backpack 1. The first shoulder strap 4 and the second shoulder strap 5 are connected by a telescopic buckle and slidably connected to the sliding grooves 2 via the slider 3. Therefore, the adjustment range can be increased by adjusting the position of the slider 3 within the sliding grooves 2.

[0029] like Figures 3 to 8As shown, a shoulder support 6 is fixedly connected to the first shoulder strap 4. The first shoulder strap 4 and the shoulder support 6 are fixedly connected by Velcro. The shoulder support 6 consists of a sweat-absorbing layer 14, a sponge pad 15, and a breathable foam pad 16. The sweat-absorbing layer 14, sponge pad 15, and breathable foam pad 16 are composed of fabric to form the shoulder support 6. One side of the shoulder support 6 is hook-and-loop, and the first shoulder strap 4 is fleece-like. One end of the slider 3 is provided with a slot 7. A locking block 8 is movably inserted into the slot 7. Limiting blocks 17 are fixedly connected to both sides of the locking block 8. The slider 3 is provided with a locking block 17 located in the slot 7. The groove of the limiting block 17 is used for cooperation. A spring 9 is fixedly connected between the card block 8 and the slot 7. The schoolbag 1 is provided with at least one insertion hole 10 that cooperates with the card block 8. A push block 11 is movably inserted into the insertion hole 10. A pressing plate 12 is fixedly connected to one end of the push block 11. The distance between the card block 8 and the insertion hole 10 is controlled by the action of the pressing plate 12 and the push block 11, so that the slider 3 can slide in the slide groove 2. The spring 9 facilitates the reset of the card block 8. The at least one insertion hole 10 on the schoolbag 1 makes it easy to make the positions on both sides the same.

[0030] In practical use, when adjusting the backpack 1 using the telescopic buckle, wear the adjusted backpack 1 on your back, then slide the sleeve 18 until it is positioned in the middle of your shoulder. Then remove the backpack, remember its position, and attach the shoulder support 6. The shoulder support position can be changed according to the adjustment of the first shoulder strap 4. When adjusting the first shoulder strap 4 is insufficient, push the pressing plate 12. The pressing plate 12 moves the push block 11, which in turn moves the locking block 8. At this time, the spring 9 is compressed and deformed under the pushing force. When the locking block 8 is no longer in contact with the insertion hole 10, the slide... Move slider 3 and adjust it to the appropriate position. At this time, spring 9 generates elastic force, which pushes block 8 to move. Block 8 enters the insertion hole 10 and pushes push block 11 to move, so that pressing plate 12 returns to the initial position. Then adjust the other side to the same position. Then put on backpack 1 and adjust the length of first shoulder strap 4 to the appropriate position through telescopic buckle. Then move sleeve 18 to shoulder. Then take off backpack 1 and remember the position. Then move sleeve 18 to second shoulder strap 5. Then attach shoulder support 6 to first shoulder strap 4. Repeat the same steps on the other side. The adjustment is now complete.
