Description

Technical Field

[0001] This application relates to the technical field of metal frame backpacks, and more particularly to a detachable metal frame backpack. Background Technology

[0002] Because some backpacks have a large capacity, the pressure on the user's neck and back can be relatively high if the contents are heavy. To address this, some existing technologies include a support frame on the side of the backpack that fits against the back to provide stronger support, effectively distribute the weight of the backpack, and improve stability and comfort when carrying heavy loads.

[0003] In the prior art, to improve the adaptability of the metal frame backpack, some designs make the metal frame detachable. However, the connection between the metal frame and the backpack in the prior art is usually achieved by setting a connector on the backpack to install the metal frame. This has low applicability for some other backpacks that do not have a connector, so further improvements are needed. Utility Model Content

[0004] To improve the applicability of the support, this application provides a detachable metal support backpack.

[0005] This application provides a detachable metal frame backpack, which adopts the following technical solution:

[0006] A detachable metal frame backpack includes a back panel, a frame disposed on the back panel away from the back, and a backpack disposed on the frame. The back panel has shoulder straps on the side closest to the back, and a connector on the side away from the back. The backpack is detachably connected to the frame via the connector. The frame includes two vertical bars, a first horizontal bar disposed between the two vertical bars, two vertical rods perpendicular to the two vertical bars, and a second horizontal bar disposed between the two vertical bars. The first horizontal bar is located at the upper end of the vertical bars, the vertical rods are located at the lower end of the vertical bars, and the second horizontal bar... The length direction is parallel to the length direction of the first horizontal bar; several connectors are spaced apart along the height direction of the vertical bar; the side of the bracket is L-shaped; the first horizontal bar and two vertical bars form an abutment area for the backpack to abut; the two vertical bars and the second horizontal bar form a placement area for the backpack to be placed; the connectors include several first buckles and a fourth connecting strap disposed on the first buckles; the first buckles include a female buckle fixedly connected to the back panel and a female buckle inserted into the female buckle; the fourth connecting strap is disposed on the female buckle; the abutment strap abuts against the outer surface of the backpack away from the bracket.

[0007] By adopting the above technical solution, the backpack is placed in the placement area and abutted against the abutment area. Then, the fourth connecting strap abuts against the backpack, and the male buckle is inserted into the female buckle, thereby securing the backpack. The placement area facilitates placement and further distributes the backpack's weight, improving stability when carrying it. Since several connectors are provided, the backpack is secured through the insertion of male and female buckles, resulting in relatively stable fixation. Using this method, backpacks of different sizes can be placed in the placement area and secured using the connectors, thus improving the applicability of the support frame.

[0008] Preferably, both ends of the fourth connecting strap are threaded through the sub-fastener, and the opposite side walls of the free end of the fourth connecting strap are fixedly connected with fixing straps, and the two fixing straps are respectively fixedly connected with a fourth female hook and loop fastener and a fourth sub-hook fastener adhered to the fourth female hook and loop fastener.

[0009] By adopting the above technical solution, the excess part of the fourth connecting strip is wound up and then fixed by setting a fourth female hook and loop fastener and a fourth female hook and loop fastener attached to the fourth female hook and loop fastener, which reduces the possibility that the excess fourth connecting strip may slip off the female or female fastener when it is exposed and pulled.

[0010] Preferably, the length of the back plate is longer than the length of the vertical rod, and a shaping plate is embedded in the middle of the back plate, the length direction of the shaping plate being parallel to the height direction of the back plate.

[0011] By adopting the above technical solution, since some backpacks are quite tall, if the vertical bar is set too long, although it can accommodate taller backpacks, the vertical bar may collide with the head and neck, reducing comfort. Therefore, the length of the vertical bar that can be set is limited. In order to reduce the possibility of the backpack directly pressing against the head, the length of the back panel is increased, and a shaping plate is set inside the back panel to shape the extended back panel. This improves the support of the extended back panel for the backpack, while also reducing the possibility of the back panel being pressed against the head, thereby improving the comfort of using the bracket.

[0012] Preferably, the upper end of the shaping plate is arc-shaped in the direction away from the bracket.

[0013] By adopting the above technical solution, the upper end of the shaping plate is set in an arc shape away from the support, which can provide a certain prestress and give the backpack relatively high support force, thereby further reducing the possibility of the back panel pressing against the head or neck when under pressure.

[0014] Preferably, the back panel is provided with a first cushioning pad at the waist, and side waist belts are provided on both sides of the first cushioning pad. The free ends of the two side waist belts are provided with first connecting straps, and the free ends of the two first connecting straps are respectively fixedly connected with the male buckle and the female buckle of the first buckle. The female buckle is inserted into the male buckle, and a second cushioning pad is provided on the surface of the side waist belts near the waist.

[0015] By adopting the above technical solution, with the side waist belt and the first buffer belt, the length of the second connecting belt can be adjusted according to one's waist circumference to fit the waist. The first and second buffer pads can also buffer the vibrations brought about by the backpack during walking, thereby reducing the load on the waist.

[0016] Preferably, the back plate is provided with a third buffer pad on both sides of the shaping plate. The third buffer pad is located on the side of the back plate away from the bracket. The lower end of the third buffer pad is connected to the first buffer pad, and the upper end of the third buffer pad is higher than the height of the first crossbar.

[0017] By adopting the above technical solution and setting a third cushioning pad, a certain gap is left between the back and the back panel to allow for ventilation of generated heat and sweat, thereby improving comfort. Since the upper end of the third cushioning pad is higher than the height of the first crossbar, it can reduce the discomfort caused to the back by the support structure through the back panel.

[0018] Preferably, the bracket is detachably connected to the back plate, and a fixing layer is provided on the surface of the back plate near the bracket. A space is formed between the fixing layer and the back plate for the top of the bracket to be inserted. A fixing member for fixing the bracket is provided at the lower end of the back plate.

[0019] By adopting the above technical solution, the bracket is detachably connected to the back plate, the fixing layer fixes the upper end of the bracket through friction with the bracket, and the fastener is used to fix the lower end of the bracket.

[0020] Preferably, the bracket further includes a connecting rod disposed at the lower end of the two vertical rods, and the fixing member includes abutment strips disposed on both sides of the connecting rod. The abutment strips are fixedly connected to the back plate. Several abutment strips are spaced apart along the length of the connecting strips. The two abutment strips are respectively fixedly connected to a male buckle and a female buckle of a snap fastener. The male buckle of the snap fastener is engaged with the female buckle.

[0021] By adopting the above technical solution, the female buckle in the snap fastener is engaged with the female buckle to fix the connecting rod, thereby limiting the possibility of the bracket slipping and detaching from the back plate along the height direction.

[0022] Preferably, the bottom of the back panel is connected to a T-shaped mounting strap. The mounting strap includes a horizontal strap and a vertical strap perpendicular to the horizontal strap. The two opposite surfaces of the horizontal strap at its ends are respectively provided with a second sub-hook and a second female hook and loop fastener, and the second sub-hook and loop fastener are adhered to the second female hook and loop fastener. The vertical strap is located in the middle of the horizontal strap. The two opposite surfaces of the vertical strap away from the end of the horizontal strap are also respectively provided with a second sub-hook and a second female hook and loop fastener. The connection between the horizontal strap and the vertical strap is located below the placement area, and the ends of the horizontal strap and the ends of the vertical strap are located at the upper end of the placement area.

[0023] By adopting the above technical solution, the connection between the horizontal and vertical straps is placed against the lower part of the placement area, and the ends of the horizontal and vertical straps are attached to the upper part of the placement area by the second sub-hook and hook and loop fastener and the second female hook and loop fastener. This further fixes the lower end of the bracket and provides a support plate for the placement area, reducing the possibility of backpacks placed on the bracket falling from the hollow position of the placement area. This is suitable for backpacks with a small radial cross-section, further improving the applicability of the bracket.

[0024] Preferably, the lower surface of the backpack is provided with a third sub-hook and loop fastener that is attached to the second female hook and loop fastener, or a third female hook and loop fastener that is attached to the second sub-hook and loop fastener.

[0025] By adopting the above technical solution, a third sub-hook and hook and loop fastener or a third female-hook and loop fastener is provided on the backpack to be attached to the second female-hook and hook and loop fastener respectively, thereby further securing the backpack and reducing the possibility of shaking.

[0026] In summary, this utility model has the following beneficial effects:

[0027] The backpack is secured by placing it in the designated placement area and then attaching it to the contact area. The first connecting strap is then attached to the backpack, and the male buckle is inserted into the female buckle. The placement area facilitates placement and further distributes the backpack's weight, improving stability when carrying it. Since several connectors are provided, the backpack is secured through the insertion of male and female buckles, resulting in a relatively stable fixation. Using this method, backpacks of different sizes can be placed in the placement area and secured using the connectors, thus increasing the applicability of the support frame.
