Description

Technical Field

[0001] This utility model relates to the field of mesh chair technology, specifically a mesh chair. Background Technology

[0002] Existing mesh chairs typically have a backrest made of a mesh frame structure, offering limited functionality and lacking integrated adjustable headrests or lumbar support modules. This design flaw results in the user's head, neck, or lower back not receiving effective support and relaxation during prolonged sitting or lying down.

[0003] Therefore, there is an urgent need to develop a mesh chair to solve the problems in the existing technology. Utility Model Content

[0004] The purpose of this utility model is to provide a mesh chair that can support the head or waist, and has a simple structure and is easy to use, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A mesh chair, characterized in that it comprises: a mesh chair body; a first slide rail provided on the backrest of the mesh chair body; the first slide rail being fixedly connected to the mesh chair body; a sliding backrest provided on the first slide rail; the sliding backrest comprising: a snap-fit ​​portion and a backrest portion; the snap-fit ​​portion snapping into the first slide rail; and the backrest portion being fixedly connected to the snap-fit ​​portion; the length extension direction of the first slide rail is parallel to the length extension direction of the backrest of the mesh chair body.

[0006] By adopting the above technical solution, the first slide rail is located from the top to the bottom of the mesh chair body, which ensures that the sliding backrest can slide and switch between the user's head and neck position and the waist position. Through the engagement of the locking part with the first slide rail, it can be ensured that the sliding backrest will not slip around. In addition, the user can add the sliding backrest on the first slide rail to take into account the support of the head, neck and waist.

[0007] As a further embodiment of this utility model: the snap-fit ​​part includes: a connecting rod, a push rod, a first spring, and an arc-shaped block. The connecting rod is fixedly connected to the headrest part, and the interior of the connecting rod is hollow. The push rod is L-shaped and is inserted into the interior of the connecting rod, and the push rod is slidably connected to the connecting rod. The first spring is disposed inside the connecting rod, one end of the first spring is fixedly connected to the interior of the connecting rod, and the other end of the first spring is fixedly connected to the push rod. The arc-shaped block is disposed on the push rod and is fixedly connected to the push rod.

[0008] By adopting the above technical solution, the user can press the L-shaped push rod inward, causing the push rod to drive the arc-shaped block to retract inward, thereby adjusting the upper and lower positions of the sliding headrest on the first guide rail.

[0009] As a further embodiment of this utility model: an arc-shaped groove is provided on the first slide rail, and the arc-shaped block engages with the arc-shaped groove to achieve the engagement of the engaging part with the first slide rail.

[0010] By adopting the above technical solution, after the push rod is stopped being pressed, the push rod will be subjected to the force applied by the first spring, thereby causing the arc-shaped block to spring outward and lock into the arc-shaped groove, thereby fixing the sliding pillow on the first guide rail.

[0011] As a further embodiment of this utility model: the interior of the headrest is hollow, and a second slide rail is provided inside the headrest. An auxiliary headrest is provided on the second slide rail, and the auxiliary headrest is slidably connected to the second slide rail.

[0012] By adopting the above technical solution, when the backrest supports the waist, the auxiliary backrest can slide out from inside the backrest along the second slide rail, thus widening the lumbar support space. Furthermore, the hollow part of the backrest has a rigid frame covered with an elastic material such as sponge. When the auxiliary backrest slides out from its interior, it will not affect the support of the backrest.

[0013] As a further embodiment of this utility model: the auxiliary headrest includes: a sliding plate, a roller and a second headrest, the roller is disposed on the sliding plate and is fixedly connected to the sliding plate, the sliding plate is slidably connected to the second slide rail through the roller, the second headrest is disposed on the sliding plate and is slidably connected to the sliding plate.

[0014] By adopting the above technical solution, the sliding plate and the second slide rail are slidable through the roller, which reduces friction, improves durability and sliding efficiency, and reduces noise during use.

[0015] As a further embodiment of this utility model: a second spring is provided on the sliding plate, the second spring is disposed between the sliding plate and the second pillow, one end of the second spring is fixedly connected to the sliding plate, and the other end of the second spring is fixedly connected to the second pillow.

[0016] By adopting the above technical solution, the second spring applies force to the second pillow when the sliding plate slides out from the inside of the pillow part, thereby causing the second pillow to pop out. There is a limiting block between the second pillow and the sliding plate. Finally, the second pillow can be bounced to the same side as the pillow part by the force applied by the second spring, which improves the comfort of lumbar support. In addition, the second spring can play a shock absorption role when supporting the waist.

[0017] Compared with existing technologies, the advantages of this utility model are: the sliding headrest design allows a headrest to be freely adjusted on the backrest rail, taking into account the support needs of the head, neck, and waist; its snap-fit ​​structure ensures stable positioning, the auxiliary headrest can slide out to widen the support surface, and springs enhance comfort and shock absorption. The overall structure is simple and practical, effectively improving the support performance and health protection of the mesh chair.

[0018] Other features and advantages of this utility model will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description
