Description

Technical Field

[0001] The utility model belongs to the technical field of seat production equipment and relates to a seat mesh machine pressing tool. Background Art

[0002] As a kind of daily necessities, chairs are widely used in every corner of life. Due to the different structures and materials of chairs, the comfort they bring to people will also be different. In the prior art, there is a chair made of mesh fabric, which has the characteristics of comfort, breathability, heat dissipation, etc., can relieve fatigue caused by office work, and is suitable for people who need to sit for a long time.

[0003] Most of the seats with mesh fabric attached to the frame are produced manually. The operator needs to tighten the mesh fabric while inserting it into the groove at the edge of the frame, and then fix the embedded mesh fabric. During the fabrication process, the mesh fabric attached to the seat needs to be tighter because the seat is subject to greater pressure when in use. Manual fabrication may result in a loose connection between the mesh fabric and the frame, which may become loose after a period of use. In addition, the frame cannot be fixed during fabrication, which increases the difficulty of operation and reduces production efficiency. Summary of the invention

[0004] The utility model aims at the problems existing in the prior art and proposes a seat mesh machine pressing tool. The technical problem to be solved by the utility model is: how to make the mesh more firmly pressed on the seat frame.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a seat mesh machine pressing tool, including a base, a mounting platform is provided in the middle of the top of the base, first cylinders are provided on both sides of the top of the base, a piston rod is provided at one end of the first cylinder, a fixed pressure block is provided on the piston rod, a fixed seat frame is provided on the mounting platform, a first side edge and a second side edge are provided at the outer edge of the seat frame, a groove structure is formed between the first side edge and the second side edge, a guide slope is provided at one end of the pressure block close to the seat frame, and the guide slope is abutted against the second side edge.

[0006] In the present solution, the side edge of the seat frame is composed of a first side edge at the top and a second side edge at the bottom. The groove structure between the first side edge and the second side edge is used to clamp the mesh. The seat frame to be pressed against the mesh is fixed on the mounting table. The first cylinders on both sides control the piston rods to extend toward the seat frame, and the seat frame is squeezed from both sides at the same time by the pressure block. Since the guide slope of the pressure block abuts against the second side edge, the second side edge will move downward along the guide slope, so that the notch of the groove structure is enlarged, and the production personnel can insert the mesh into the groove more conveniently, and can also insert the mesh deeper into the groove, thereby improving the firmness of the mesh control.

[0007] In the above-mentioned seat mesh machine pressing tool, a fixed support frame is provided at the bottom of the seat frame, and a mounting hole is provided at the bottom of the support frame. The support frame connects the front end and both sides of the seat in the seat frame, and is also connected to the frame at the back of the seat to improve the stability of the seat frame structure. After the mesh on the seat frame is formed, the mounting hole is used to install the rotating shaft at the bottom to enable the seat to have a rotating function.

[0008] In the above-mentioned seat mesh machine pressing tool, the mounting platform is provided with a limit column, the limit column is inserted into the mounting hole and connected by clamping, and the mounting platform is also provided with a limit groove, the limit groove is connected by clamping with both sides of the support frame. During the manufacturing process, the mounting hole is inserted into the limit column, and the two sides of the support frame are clamped into the limit groove, which can prevent the seat frame from shaking.

[0009] In the above-mentioned seat mesh machine pressing tool, the second cylinder is provided on both sides of the mounting platform, and a hinged pressing piece is provided on the top of the second cylinder, and one end of the pressing piece is against the support frame. The second cylinder can drive the pressing piece to press down, and the pressing piece can fix the support frame part on the mounting platform after being pressed down, so as to improve the stability during the pressing process.

[0010] In the above-mentioned seat mesh machine pressing tool, a hinged connecting rod is provided on one side of the top of the second cylinder, and the other end of the connecting rod is hingedly connected to the middle end of the pressing member. The specific pressing structure of the pressing member is that the second cylinder drives one end of the pressing member to move upward, and since the middle end of the pressing member is hinged to the connecting member, the pressing member rotates with the hinge point as the center of the circle, so that the other end abuts against the support frame, thereby achieving the function of fixing the seat frame.

[0011] In the above-mentioned seat mesh machine pressing tool, armrest insertion holes are provided at both ends of the connection between the support frame and the seat frame. The armrest insertion holes are used to install the armrests on the seat.

[0012] In the seat mesh machine pressing tool, the pressing block is provided with fixed guide rods on both sides, and one end of the first cylinder is provided with a fixed support plate, and the guide rods on both sides are slidably connected with the support plate. The guide rods move with the movement of the pressing block, and can play a guiding role in the process of the pressing block being ejected, preventing the pressing block from deviating up and down, and ensuring that the pressing block structure can open the notch of the groove.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] 1. In this solution, since the guiding slope of the pressing block is in contact with the second side edge, when the pressing block presses the seat frame, the second side edge will move downward along the guiding slope, so that the notch of the groove structure is enlarged, and the production personnel can insert the mesh into the groove more conveniently, and can also insert the mesh deeper into the groove, thereby improving the firmness of the mesh control.

[0015] 2. In this solution, the second cylinder drives one end of the pressing piece to move upward. Since the middle end of the pressing piece is hinged to the connecting piece, the pressing piece will rotate with the hinge point as the center of the circle, so that the other end will abut against the support frame, thereby fixing the seat frame, improving the stability of the seat frame installed on the mounting table, and making it convenient for production personnel to touch the mesh on the frame.
