Description

Technical Field

[0001] This utility model belongs to the field of seat processing technology, specifically relating to a tooling for an auxiliary mesh for quick-assembly chairs. Background Technology

[0002] Currently, people have an increasing demand for chairs, which has led to the development of various types of chairs, such as lounge chairs, office chairs, and dining chairs. Mesh chairs are one such type. Many chairs use mesh fabric combined with the seat frame to improve breathability and heat dissipation, as well as to save materials and reduce costs. These types of chairs are collectively referred to as mesh chairs.

[0003] Existing mesh chairs mainly consist of a frame and a mesh fabric. The mesh fabric is taut and wrapped around the frame and fixed to the frame by pressure strips, fasteners, or fasteners. However, the assembly process of tautly fixing the mesh fabric to the frame is generally done manually. The operator needs to press the edge of the mesh fabric inward along the outer periphery of the frame and embed it into the frame while continuously tightening the mesh fabric so that it can be tautly connected to the seat.

[0004] The above processing method has two main drawbacks. First, the long-term pressing process is labor-intensive for operators. Second, the efficiency of manual processing without external assistance is relatively low, which does not meet the current market demand. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides a tooling for auxiliary mesh fabric for quick-assembly chairs, in order to solve the technical problems of low processing efficiency and high labor intensity for operators in existing mesh fabric chairs.

[0006] To achieve the above objectives, the specific technical solution of this utility model is as follows:

[0007] A tooling for an auxiliary mesh for a quick-assembly chair includes a support base, and a clamping assembly and a limiting support assembly mounted on the support base.

[0008] The limiting support assembly includes a centrally located limiting seat and two sets of symmetrically arranged support sleeves on the bracket base. Each set of support sleeves includes multiple support columns. The support columns are arranged in a curved shape on the bracket base. The limiting seat has a slot.

[0009] The drive end of the clamping component can move outward or inward to press or release the processed seat back frame supported by each support column.

[0010] Furthermore, each of the support columns is equipped with an adjustment seat at its bottom. The adjustment seat has an adjustment groove for sliding contact with the support base. A screw is installed within the adjustment groove.

[0011] Furthermore, each set of support sleeves contains three support columns. These three support columns are sequentially designated as a first support column, a second support column, and a third support column. Both the first and third support columns are provided with guide ramps facing the second support column.

[0012] Furthermore, the clamping assembly includes a limiting clamping component and a telescopic cylinder. The telescopic cylinder is fixed to the bracket base. The limiting clamping component is divided into an inner connecting portion and an outer clamping portion. The connecting portion is fixed to the telescopic end of the telescopic cylinder. The clamping portion is hook-shaped.

[0013] Furthermore, the support base is divided into a first support located above and a second support located below. The first support is rotatably connected to the second support via a rotating disk.

[0014] Furthermore, the top of the second bracket is provided with an inclined surface. The first bracket is mounted on the inclined surface.

[0015] Furthermore, the bottom of the second bracket is equipped with multiple casters.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. This utility model features a limiting bracket and two sets of symmetrically arranged support sleeves on the support base. By arranging the support columns in the support sleeves in a curved shape, they can fit into various parts of the processed seat back frame, providing support and limiting for each part, thus ensuring the stability of the processed seat back frame during the mesh fabrication process.

[0018] 2. This utility model provides a clamping component in the middle of the support base. The driving end of the clamping component can move outward or inward to press or release the back frame of the processed seat supported by each support column. When pressing, the middle of the back frame of the processed seat is compressed downward, and the two sides of the back frame of the processed seat will be concave towards the middle due to the pressure, making the subsequent meshing operation easier.

[0025] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper side", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] like Figure 1 and 2 As shown, a tooling for an auxiliary upholstery for a quick-assembly chair includes a support base 1, and a clamping assembly 2 and a limiting support assembly 3 mounted on the support base 1. The limiting support assembly 3 includes a centrally located limiting seat 4 and two sets of support sleeves symmetrically arranged on the support base 1. Each set of support sleeves includes three support columns 5. The three support columns 5 are arranged in a curved shape on the support base 1, conforming to various parts of the seat back frame 8 being processed, forming support. The limiting seat 4 has a V-shaped groove, which can clamp and fix the bottom of the seat back frame 8 being processed. The driving end of the clamping assembly 2 can move outward or inward, realizing the pressing or releasing of the seat back frame 8 supported by each support column 5.

[0028] In this embodiment, as Figure 3 and 4As shown, each support column 5 has an adjusting seat 6 at its bottom. The adjusting seat 6 has an adjusting groove for sliding engagement with the support base 1. When the adjusting seat 6 slides to the designated position, the position of the adjusting seat 6 is locked by tightening the screws set in the adjusting groove.

[0029] Furthermore, the three support columns 5 are sequentially divided into a first support column 5-1, a second support column 5-2, and a third support column 5-3. Both the first support column 5-1 and the third support column 5-3 are provided with guide ramps 5-4 facing the second support column 5-2. When the worker places the seat back frame 8 to be processed on the first support column 5-1 and the third support column 5-3, it can slide towards the second support column 5-2 via the guide ramps 5-4, facilitating the second support column 5-2 to quickly engage with the first support column 5-1 and the third support column 5-3 to provide support for the seat back frame 8 being processed.

[0030] like Figure 5 As shown, the clamping assembly 2 includes a limiting clamping member 2-1 and a telescopic cylinder 2-2. The telescopic cylinder 2-2 is fixed to the bracket base 1 and is used to drive the limiting clamping member 2-1 to rise or fall. The limiting clamping member 2-1 is divided into an inner connecting part and an outer clamping part. The connecting part is fixed to the telescopic end of the telescopic cylinder 2-2. The clamping part is hook-shaped. When the limiting clamping member 2-1 is pressed down under the drive of the telescopic cylinder 2-2, the hook-shaped clamping part forms a limiting fixation on the middle frame of the processed seat back frame 8.

[0031] like Figure 2 As shown, the support base 1 is divided into a first support 1-1 located at the top and a second support 1-2 located at the bottom. The first support 1-1 is rotatably connected to the second support 1-2 via a rotary disk, allowing the operator to rotate the first support 1-1 as needed to perform meshing operations on different parts of the seat back frame 8 being processed.

[0032] Furthermore, the top of the second bracket 1-2 is provided with an inclined surface, which makes the first bracket 1-1 and the clamping component 2 and the limiting support component 3 set on the first bracket 1-1 inclined, so that the workers can place the processed seat back frame 8 on the limiting support component 3 and perform subsequent mesh processing.

[0033] Furthermore, the bottom of the second support 1-2 is provided with multiple casters 7 to enable the free movement of the first support 1-1.

[0034] The working principle of this utility model is as follows:

[0035] Initially, the workers tighten three screws in the middle of the top of the seat back frame and then manually fabricate a mesh over that area. Next, the seat back frame is placed on the limiting support assembly 3. The outer edges of the seat back frame are limited and supported by the limiting brackets 4 and the support columns 5 in the limiting support assembly 3.

[0036] Activate telescopic cylinder 2-2, which drives the limit clamp 2-1 to press down, causing the middle part of the seat back frame to be processed to compress downward. The two sides of the seat back frame will be concave towards the middle due to the pressure, making the subsequent meshing operation easier. When the pressure on the seat back frame is released, the two sides of the seat back frame will return to their original position, so that the mesh fabric is in a taut state, ensuring the tightness of the mesh fabric after processing.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
