Technical Field

[0001] This utility model relates to the field of backpack technology, and in particular to a travel backpack with back correction function. Background Technology

[0002] A backpack is a bag worn on both shoulders, also known as a shoulder bag or shoulder bag. It typically has two shoulder straps to balance the load on both shoulders, making carrying items more comfortable and convenient. Backpacks are widely used in daily life, school, travel, and outdoor activities, and are popular due to their convenience and practicality.

[0003] For example, patent application CN209788920U in the prior art includes a backpack body, an mounting plate on the back of the backpack body, a waist belt sewn onto the lower part of the backpack body, and a dovetail-shaped slide rail on the mounting plate, on which a correction component is slidably engaged. This utility model has a simple structure and is convenient and quick to use, effectively preventing and correcting hunchback caused by prolonged backpack carrying.

[0004] However, these backpacks have obvious adaptation defects: the telescopic adjustment structure of their correction components is fixed after being adjusted to the appropriate length and cannot adapt to the user's dynamic movements (such as walking, bending over, turning around); during travel, users need to move frequently, and the fixed length correction components will restrict the freedom of body movement, which not only reduces the comfort of carrying, but may also cause resistance to body movements due to rigid constraints. Long-term use can easily cause back pressure and even affect the correction effect.

[0005] Therefore, it is necessary to provide a travel backpack with back correction function to solve the above-mentioned technical problems. Utility Model Content

[0006] This invention provides a travel backpack with back correction function, which solves the problem that the correction components of existing corrective backpacks are fixed structures, which cannot adapt to the user's dynamic movements, restrict the freedom of movement, and easily cause a feeling of pressure.

[0007] To solve the above-mentioned technical problems, this utility model provides a travel backpack with back correction function, comprising: Backpack; Mounting components are mounted on the side of the backpack; A buffer assembly is disposed on one side of the mounting assembly.

Figure 3 for Figure 2 The diagram shows the structural layout of the mounting components and buffer components. Figure 4 for Figure 3 The diagram shows a cross-sectional view of the threaded rod.

[0019] A travel backpack with back correction function includes: backpack 1; Mounting component 2 is mounted on the side of the backpack 1; A buffer assembly 3 is disposed on one side of the mounting assembly 2. The buffer assembly 3 includes a threaded sleeve 31. The top and bottom of the inner side of the threaded sleeve 31 are threadedly connected to threaded rods 32. The interior of each of the two threaded rods 32 is provided with a square groove 35. A square block 36 is slidably connected to the inner side of the square groove 35. An extension rod 34 is fixedly installed on one side of the square block 36. A buffer spring 37 is sleeved on the outer side of the extension rod 34. The buffer spring 37 is disposed on the inner side of the square groove 35. Correction component 4 is disposed on one side of the buffer component 3.

[0020] The mounting assembly 2 includes a mounting plate 21, which is fixedly mounted on the side of the backpack 1. Guide rails 22 are fixedly mounted on both ends of one side of the mounting plate 21, and grooves 23 are provided on the opposite sides of the two guide rails 22.

[0021] The corrective assembly 4 includes an arc-shaped corrective plate 41. A buffer pad 42 is fixedly installed on one side of the arc-shaped corrective plate 41. Mounting blocks 46 are fixedly installed at both ends of the top and bottom of the other side of the arc-shaped corrective plate 41. A connecting rod 45 is fixedly installed on one side of the mounting block 46. A rotating seat 44 is rotatably connected to the outer side of the connecting rod 45. A moving rod 43 is fixedly installed on one side of the rotating seat 44. Both ends of the moving rod 43 are slidably connected to the inner side of the slide groove 23. The side of the moving rod 43 is fixedly installed to the end face of the extension rod 34.

[0022] The buffer assembly 3 also includes a handle 32, which is fixedly installed on the outer side of the threaded sleeve 31.

[0023] Mounting plate 21 is a rigid plate, providing a stable mounting base for buffer assembly 3 and straightening assembly 4; guide rail 22 and slide groove 23 cooperate to provide a sliding track for moving rod 43, ensuring smooth movement of straightening assembly 4; The curved correction board 41 conforms to the curve of the human back, providing uniform corrective support and preventing hunchback; the cushioning pad 42 is made of breathable sponge material, which enhances carrying comfort and avoids discomfort caused by prolonged pressure; the moving bar 43 slides along the slide groove 23 and works with the cushioning component 2 to achieve telescopic cushioning. Rotating the handle 32 can drive the threaded sleeve 31 to rotate, causing the upper and lower threaded rods 33 to move relative to or in opposite directions, adjusting the initial length and tension of the buffer assembly 3 to suit the back support needs of users of different body types; the square block 36 and the square groove 35 cooperate to prevent the extension rod 34 from rotating and ensure the smooth extension and retraction of the buffer spring 37; the buffer spring 37 provides elastic cushioning force to absorb the impact force when the user moves and avoid rigid constraints.

[0024] The working principle of the travel backpack with back correction function provided by this utility model is as follows: According to the user's body shape, the rotating handle 32 drives the threaded sleeve 31 to rotate, and adjusts the extension length of the threaded rod 33 so that the buffer pad 42 of the arc-shaped correction plate 41 fits against the back and provides appropriate correction support. When walking or bending over during travel, the body movement causes the arc-shaped correction plate 41 to move. Through the connecting rod 45 and the rotating seat 44, the moving rod 43 slides along the slide groove 23. At the same time, the extension rod 34 pushes the square block 36 to compress or stretch the buffer spring 37. The elastic force of the buffer spring 37 absorbs the impact force of the movement, so that the correction component 4 adapts to the body's dynamic deformation, avoids restricting the degree of freedom of movement, and at the same time maintains the correction support. The curved correction board 41 always fits the back, guiding the user to maintain an upright posture through physical support and preventing hunchback; the cushioning pad 42 enhances comfort, and the breathable material avoids stuffiness from prolonged carrying.

[0025] Compared with related technologies, the travel backpack with back correction function provided by this utility model has the following beneficial effects: The backpack 1, mounting component 2, cushioning component 3, and correction component 4 work together to provide support for the back of users of different body types. When carrying the backpack during travel, the threaded sleeve 31 can be rotated to adjust the extension and retraction of the threaded rod 33, which can be adapted to the back support needs of users of different body types. During dynamic movements such as walking and bending over, the cushioning spring 37 slides along the square groove 35 through the square block 36 to achieve elastic cushioning, allowing the correction component 4 to adapt to the deformation of the body without restricting the degree of freedom of movement. This solves the problem of strong pressure and limited movement of fixed correction structures, and balances the correction effect with carrying comfort, adapting to the needs of various activities during travel.
