Description

Technical Field

[0001] This utility model relates to the field of backpacks, specifically a sliding structure backpack. Background Technology

[0002] Backpacks, as an indispensable item in daily life, are widely used due to their convenience and practicality. Whether going to school, work, or engaging in outdoor activities, backpacks play an important role. However, during prolonged use, the shoulder straps can easily cause shoulder fatigue under the weight. This shoulder fatigue not only affects the user's comfort but may also pose a potential threat to their health, potentially leading to muscle strain or other related health problems in the long run.

[0003] To effectively reduce pressure on the shoulders, some backpacks are designed with a waist belt, which users can fasten around their waist to distribute some of the weight. This design does reduce shoulder strain to some extent, making the carrying experience more comfortable. However, when carrying heavy items, the waist belt may not provide sufficient support and may not effectively reduce shoulder pressure.

[0004] In addition, some backpack designs incorporate elastic structures at the bottom of the shoulder straps to reduce weight. While this design theoretically helps alleviate shoulder strain through elasticity, uneven elasticity distribution often occurs during actual use. This uneven distribution can also exacerbate shoulder discomfort.

[0005] In conclusion, although existing backpack designs take into account methods to reduce shoulder pressure to some extent, further innovation and improvement are still needed to better meet user needs and enhance the carrying experience. Utility Model Content

[0006] In response to the shortcomings of existing technologies, this utility model proposes a sliding structure bag, which aims to solve the problem of shoulder fatigue caused by the pressure and burden on the shoulders when carrying a backpack for a long time.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A sliding structure bag includes a back panel, a telescopic spring, a slide rail, and a slide base. The slide base further includes a fixing hole and a slide groove. The backpack straps are connected to the left and right sides of the back panel, respectively. The slide base is fixedly installed on the bag body. The telescopic spring is fixedly disposed at the lower end of the back panel and the upper end of the slide base. The upper part of the slide rail is fixedly connected to the middle part of the back panel, and the lower part of the slide rail passes through the slide base and is slidably connected to it.

[0009] Preferably, there are two telescopic springs, which are respectively installed on the left and right sides of the slide rail, and the upper and lower ends of the telescopic springs are respectively fixedly connected to the lower end of the back plate and the upper end of the slide rail seat.

[0010] Preferably, the slide seat has symmetrical mounting holes on both sides and a slide groove in the middle for the slide rail to pass through and for limiting the slide rail.

[0024] The attached diagram is labeled as follows: 1. Back plate; 2. Telescopic spring; 3. Slide rail; 4. Slide seat; 4a. Fixing hole; 4b. Slide groove. Detailed Implementation

[0025] 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.

[0026] like Figure 1-3 As shown, the sliding structure package of this utility model includes: a back plate 1, a telescopic spring 2, a slide rail 3, and a slide groove seat 4. The slide groove seat 4 further includes a fixed mounting hole 4a and a slide groove 4b.

[0027] The backpack's shoulder straps are connected to the left and right sides of the back panel 1, and the slide seat 4 is fixedly installed on the backpack body; the telescopic spring 2 is fixedly installed at the lower end of the back panel 1 and the upper end of the slide seat 4; the upper part of the slide rail 3 is fixedly connected to the middle part of the back panel, and the lower part of the slide rail 3 passes through the slide seat 4 and slides therewith.

[0028] Specifically, there are two telescopic springs 2, which are respectively set on the left and right sides of the slide rail 3. The upper and lower ends of the telescopic springs 2 are respectively fixedly connected to the lower end of the back plate 1 and the upper end of the slide rail seat 4.

[0029] Preferably, the slide base 4 has symmetrical mounting holes 4a on both sides and a slide groove 4b in the middle for the slide rail 3 to pass through and limit the slide rail 3. The slide base 4 is fixed to the backpack body through the mounting holes 4a.

[0030] The cross-section of the slide groove 4b corresponds one-to-one with the cross-section of the slide rail 3, and they are in clearance fit; the shape of the slide rail 3 can be a strip, a rod, etc.

[0031] like Figure 2-3 As shown, in order to ensure sliding while reducing friction between the slide block 4 and the slide rail 3, the cross section of the slide 4b can be set to be partially open.

[0032] The telescopic spring 2 is located at the upper end of the back of the backpack body. The shoulder straps are fixed to the left and right sides of the back panel 1 and are connected to the slide seat 4 through the telescopic spring 2. Since the slide seat 4 is fixed to the backpack body, the shoulder straps can achieve elastic reciprocating movement relative to the backpack body through the extension and retraction of the telescopic spring 2.

[0033] When a person is carrying a backpack under load, the telescopic spring 2 generates a rebound force, causing the shoulder straps to reciprocate vertically in cooperation with the slide rail 3 and the slide seat 4. This counteracts the force on the shoulders, reduces the load on the shoulders, and improves the user's comfort. In addition, the telescopic spring 2 is located at the upper part of the back of the backpack, which helps to distribute the weight of the entire backpack, thereby generating a relatively large rebound force, which further helps to reduce the pressure on the user.

[0034] The rebound component is designed to provide a continuous relaxation space for the body's muscles and bones through an intermittent rebound mechanism, thereby effectively protecting muscles and the spine. This design creates an environment conducive to muscle and joint stretching and relaxation, significantly reducing fatigue and making walking easier for users, avoiding adverse effects on physical development caused by improper posture.

[0035] Preferably, the sliding structure bag also features a back pad, which can be made of lightweight yet highly resilient EVA material. This material not only has excellent cushioning properties but also provides greater support. Its curved design further enhances spinal protection, allowing the user's back and spine to remain straight, thereby reducing the risk of muscle strain or hunchback caused by improper posture.

[0036] As can be seen from the accompanying drawings, in the embodiments of this utility model, the fixed connection and relative sliding of each component can be achieved by conventional methods of the prior art. The specific implementation method will not be further described in this utility model specification.

[0037] The embodiments and descriptions above are merely illustrative of the principles and preferred embodiments of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
