Description

Technical Field

[0001] This utility model relates to the field of backrest technology, specifically to a backrest with a storage mesh pocket. Background Technology

[0002] The backrest is a crucial component of a chair structure, supporting the human back. Typically located behind the user, it plays a vital role in relieving posture fatigue, improving comfort, and maintaining good posture. Widely used in office chairs, nap chairs, and other seating arrangements, it is a core component influencing user experience and health. Modern backrest designs not only emphasize basic support but also integrate ergonomic principles, materials science, and aesthetic design, striving to provide users with healthier and more comfortable posture support during extended use.

[0003] Most existing backrests only have basic support functions, mainly used to support the user's back and waist. However, they generally lack storage space design, resulting in relatively simple products. When users need to store their personal belongings, they often need additional space to place them, which is quite inconvenient. Summary of the Invention

[0004] To solve the above problems, this utility model provides a backrest with a storage mesh pocket:

[0005] A backrest with a storage mesh pocket includes a back panel assembly, which includes a back panel body. The front of the back panel body has several vertical ventilation grooves, each containing several first ventilation holes. The back panel body also has snap-fit ​​grooves symmetrically distributed on the front of the back panel body near the left and right ends. A plug-type perforated track is fixedly connected to the back of the back panel body. The top of the plug-type perforated track has a plug entrance, and the sides of the plug-type perforated track have several limiting holes. A silicone layer is fixedly connected to the plug entrance. A grooved fixing frame is integrally connected to the back of the back panel body, and several internally threaded connecting posts are fixedly connected within the grooved fixing frame. The grooved fixing frame has a storage mesh pocket assembly. The ventilation grooves are designed to conform to the curve of the human back, effectively guiding airflow and significantly enhancing back ventilation. The first ventilation holes further improve heat dissipation efficiency, effectively preventing stuffiness. The storage mesh pocket assembly effectively saves space, facilitates item storage, increases practicality, effectively prevents odor accumulation, and is easy to disassemble, clean, and replace.

[0006] Preferably, the storage net assembly includes a connecting shell, which is connected to a groove fixing frame. A storage basket is fixedly connected between the bottom inner sides of the connecting shell. The storage basket has a second ventilation hole. The structure is reliable and easy to disassemble and assemble. The storage basket forms an independent storage space, improving storage practicality and preventing odor accumulation.

[0007] Preferably, the connecting shell has a connecting hole, and a first fixing bolt is provided in the connecting hole. The first fixing bolt passes through the connecting hole and connects to the internally threaded connecting post, making the structure more stable and easier to install and disassemble.

[0008] Preferably, an internally threaded protruding post is fixedly connected to the connecting shell, a second fixing bolt is provided on the internally threaded protruding post, and a mesh bag assembly is provided on the connecting shell. The mesh bag assembly is connected to the internally threaded protruding post, which has a compact structure and is easy to replace and maintain.

[0009] Preferably, the mesh bag assembly is located above the storage basket. The mesh bag assembly includes a mesh bag frame, a mesh bag is provided inside the mesh bag frame, and a fixing hole is provided on the mesh bag frame. The second fixing bolt passes through the fixing hole and connects to the internally threaded protruding post, thereby improving the flexibility of use and storage efficiency.

[0010] Preferably, the back panel assembly is snapped with a lumbar support assembly, which is located on the front of the back panel assembly. The lumbar support assembly is snapped with the back panel body through a snap-fit ​​groove, thereby improving the comfort of lumbar support and ease of use.

[0011] Preferably, the lumbar support assembly includes a snap-fit ​​block, a connecting rod is fixedly connected to the snap-fit ​​block, a lumbar support is fixedly connected to the connecting rod, and the lumbar support has several breathable round holes to effectively relieve the stuffiness in the waist.

[0012] Preferably, the back panel assembly is provided with a headrest assembly, which is connected to a perforated track. The headrest assembly includes a headrest, and the bottom of the headrest has a slot. The slots are symmetrically arranged at the bottom of the headrest near the left and right ends. A positioning connecting rod is inserted into the slot. A spring positioning bead is provided near the bottom of the positioning connecting rod. The spring positioning bead and the limiting hole form a positioning engagement, which improves the comfort of head support and the overall practicality.

[0013] The beneficial effects of this utility model are:

[0014] 1. Through the design of the back panel assembly, the ventilation groove design conforms to the curve of the human back, which can effectively guide airflow and greatly enhance the breathability of the back. The first ventilation hole further improves the heat dissipation efficiency and effectively avoids stuffiness.

[0015] 2. The design of the storage mesh bag component effectively saves space, facilitates the storage of items, enhances practicality, ensures ventilation, effectively prevents odor accumulation, has a sturdy structure, is flexible in installation and not easily loosened, and is easy to disassemble, clean and replace.
