Description

Technical Field

[0001] This invention belongs to the field of seat assembly technology, and particularly relates to a chair back mesh fabric pressing tool and a chair back mesh fabric installation method. Background Technology

[0002] A mesh fabric is often installed on the backrest of some office chairs. Because of its good ventilation and high flexibility, the mesh fabric makes it more comfortable for users to lean against. Specifically, an adhesive strip is provided along the edge of the mesh fabric, surrounding the left, right, and top edges. This strip is embedded into the first fixing groove of the outer frame of the chair back to secure the mesh fabric. However, currently, embedding the adhesive strip into the first fixing groove requires manual pressing, which is inefficient and can cause hand pain and high labor intensity for workers over a long period. Summary of the Invention

[0003] (I) Purpose of the Invention

[0004] To overcome the above shortcomings, the present invention aims to provide a chair back mesh fabric pressing tool and a chair back mesh fabric installation method to solve the technical problems of low installation efficiency and high labor intensity of existing mesh fabrics.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A chair back mesh fabric pressing fixture includes: a mounting plate; a limiting structure disposed on one side of the mounting plate that abuts against an adhesive strip disposed on the edge of the mesh fabric and straightens the adhesive strip as it moves forward with the mounting plate; a guide structure disposed after the limiting structure that guides the straightened adhesive strip so that each part of the adhesive strip corresponds to a first fixing groove on the outer frame of the chair back; and a pressing structure disposed after the guide structure and at a height lower than the limiting structure that can press the part of the adhesive strip corresponding to the first fixing groove into the first fixing groove.

[0008] This application utilizes a pressing fixture with a limiting structure, a guiding structure, and a pressing structure. When installing the mesh fabric, the entire pressing fixture moves along the direction of the first fixing groove on the outer frame of the chair back. During the movement, the limiting structure first straightens the rubber strip of the mesh fabric, the guiding structure aligns each part of the straightened rubber strip with the first fixing groove one by one, and the pressing structure presses the part of the rubber strip corresponding to the first fixing groove one by one into the first fixing groove. The pressing fixture can embed the entire rubber strip into the first fixing groove by moving one revolution along the first fixing groove. Using the pressing fixture of this application to install the mesh fabric not only improves the efficiency of mesh fabric installation but also reduces the labor intensity of operators.

[0009] In some embodiments, an elastic buffer is provided between the mounting plate and the press-in structure;

[0010] By setting an elastic buffer on the pressing structure, the pressing structure can move up and down slightly to buffer when the pressing structure presses the rubber strip into the first fixing groove, thus avoiding hard contact between the pressing structure and the outer frame of the chair back. When the pressure applied by the pressing structure is too large, it is easy to damage the outer frame of the chair back.

[0011] In some embodiments, the limiting structure includes: two first limiting posts arranged symmetrically at the top and bottom and extending horizontally at the same time to abut against the upper and lower sides of the adhesive strip; two support posts arranged behind the two first limiting posts and extending symmetrically upwards to support the adhesive strip at a horizontal height; and two second limiting posts arranged behind the two support posts and symmetrically arranged left and right to abut against the left and right sides of the adhesive strip.

[0012] By setting the first and second limiting posts, the upper and lower sides, as well as the left and right sides, of the rubber strip can be limited. The support post can support the rubber strip at a predetermined height. Through the interaction of the first and second limiting posts and the support post, the position of the rubber strip can be limited to prevent the rubber strip from coming out of the guide structure. Furthermore, as the pressing tool moves forward, the first and second limiting posts and the support post can simultaneously straighten the rubber strip, making it easier for the pressing tool to move forward.

[0013] In some embodiments, the mounting plate includes: a first mounting plate for fixing the limiting structure and the guide structure, and a second mounting plate for fixing the press-in structure and slidably connected to the first mounting plate.

[0014] By setting up relatively sliding first and second mounting plates, the distance between the limiting structure, the guiding structure, and the pressing structure can be adjusted. When the outer frame of the chair back is a regular shape, the interval between the limiting structure, the guiding structure, and the pressing structure can be increased. In this way, the limiting structure and the guiding structure can straighten the part in front of the rubber strip in advance, avoiding the rubber strip bending and hindering the movement of the pressing tool, which can increase the forward movement speed of the pressing tool and improve the installation efficiency.

[0015] In some embodiments, it further includes: a drive device disposed on the mounting plate and drivenly connected to the press-in structure, capable of driving the press-in structure to descend below the height of the guide structure;

[0016] The height of the pressing structure can be adjusted by the drive device, and the rubber strip can be pressed into the first fixing groove at different depths to adapt to different chair back outer frames.

[0017] In some embodiments, the mounting plate is provided with an elongated hole for adjusting the mounting height of the press-in structure, which is slidably connected to the press-in structure.

[0018] By adjusting the height of the pressing structure through the elongated hole, the rubber strip can be pressed into the first fixing groove at different depths to fit the outer frame of the chair back at different depths.

[0019] In some embodiments, it further includes: a handle disposed on the mounting plate;

[0020] By setting a handle, a person can hold the handle and move the pressing tool forward to press the rubber strip into the first fixed groove.

[0021] In some embodiments, it further includes: a robotic arm connected to the mounting plate;

[0022] By setting up a robotic arm, the pressing fixture can be moved forward automatically, pressing the rubber strip into the first fixed groove, which saves more manpower.

[0023] This application also provides a method for installing a chair back mesh fabric, using the aforementioned chair back mesh fabric pressing fixture. The installation method includes the following steps:

[0024] The first end of the adhesive strip that surrounds the left, top, and right edges of the mesh fabric passes sequentially through the limiting structure, guide structure, and around the bottom of the pressing structure of the chair back mesh fabric pressing fixture;

[0025] After the first end of the adhesive strip passes through the chair back mesh fabric pressing fixture, the first end of the adhesive strip is manually inserted into the starting position of the first fixing groove of the outer frame of the chair back.

[0026] The chair back mesh fabric pressing tool moves along the shape of the first fixed groove, pressing each part of the rubber strip into the first fixed groove in sequence;

[0027] When the chair back mesh fabric pressing fixture moves to the end position near the first fixed groove, remove the chair back mesh fabric pressing fixture from the second end of the adhesive strip.

[0028] The second end of the adhesive strip is manually inserted into the end of the first fixing groove;

[0029] The underside of the mesh fabric lacking the adhesive strip is manually inserted into the second fixing groove of the outer frame of the chair back. Attached Figure Description

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0039] Please see Figures 1-6 The present invention provides a chair back mesh fabric pressing fixture, comprising: a mounting plate 1; a limiting structure 2 disposed on one side of the mounting plate 1, capable of abutting against an adhesive strip 701 disposed on the edge of the mesh fabric 7 and straightening the adhesive strip 701 as it moves forward with the mounting plate 1; a guide structure 3 disposed after the limiting structure 2, capable of guiding the straightened adhesive strip 701 so that each part of the adhesive strip 701 corresponds to a first fixing groove 601 formed on the outer frame 6 of the chair back; and a pressing structure 4 disposed after the guide structure 3 and lower in height than the limiting structure, capable of pressing the parts of the adhesive strip 701 corresponding to the first fixing groove 601 into the first fixing groove 601 one by one.

[0040] Specifically, the limiting structure 2 includes:

[0041] Two first limiting posts 201 are symmetrically arranged vertically and extend horizontally at the same time. The two first limiting posts 201 are used to limit the upper and lower sides of the adhesive strip 701.

[0042] Two support columns 202 are located after the two first limiting columns 201. The two support columns 202 are symmetrical and extend upward at the same time to support the adhesive strip 701 so that the adhesive strip 701 is at a predetermined horizontal height, specifically located just below the guide structure 3.

[0043] Two second limiting posts 203 are symmetrically arranged after the two support posts 202 to limit the left and right sides of the adhesive strip 701.

[0044] Specifically, the guide structure 3 is a limiting wheel 5. The limiting wheel 5 has a recessed groove in the middle to form a limiting groove. The width of the limiting groove matches the width of the adhesive strip 701. After the adhesive strip 701 is embedded in the limiting groove of the limiting wheel 5, the two side walls of the limiting groove can guide the position of the adhesive strip 701 so that a part of the adhesive strip 701 corresponds to the first fixing groove 601. This is equivalent to the limiting wheel 5 straightening the adhesive strip 701 so that a part of the adhesive strip 701 corresponds to the first fixing groove 601.

[0045] Specifically, the pressing structure 4 is a pressing wheel 6, whose installation height must be lower than that of the limiting wheel 5. After the limiting wheel 5 guides the rubber strip 701 to correspond to the first fixing groove 601, the pressing wheel 6 can roll over the rubber strip 701 and apply pressure to the rubber strip 701 to press the rubber strip 701 into the first fixing groove 601.

[0046] Specifically, the mesh fabric 7 includes a fabric surface 702 and an adhesive strip 701. The adhesive strip 701 extends upward from the left side of the fabric surface 702 to the upper side, then extends laterally along the upper side, and finally bends downward from the right side to form a semi-enclosed structure. Specifically, in this application, the end of the adhesive strip 701 located on the left side is referred to as the first end, and the end located on the right side is referred to as the second end.

[0047] Specifically, when installing the adhesive strip 701, the first end of the adhesive strip 701 needs to be passed sequentially through the two first limiting posts 201, the two support posts 202, the two second limiting posts 203, and the limiting groove of the limiting wheel 5, then around the bottom of the pressing wheel 6 and out of the pressing fixture. The first end is then manually pressed into the starting position of the first fixing groove 601 (the left end position of the first fixing groove 601). Then, the pressing fixture is moved along the direction of the first fixing groove 601. During the forward movement of the pressing fixture, the pressing wheel 6 gradually presses the adhesive strip 701 in. When the pressing tool moves to the end of the first fixing groove 601 (the right end of the first fixing groove 601), it needs to be removed from the second end of the adhesive strip 701. Then, the second end of the adhesive strip 701 is manually pressed into the end of the first fixing groove 601, thus completing the three-sided fixing of the mesh cloth 7. Finally, since there is no adhesive strip 701 on the lower side of the mesh cloth 7, the lower side of the mesh cloth 7 is manually embedded into the second fixing groove 602 of the outer frame 6 of the chair back.

[0048] In one embodiment, the mounting plate 1 is provided with two handles 5, and the operator can hold the handles 5 to drive the pressing tool forward along the first fixed groove 601.

[0049] In another embodiment, a robotic arm is connected to the mounting plate 1, which drives the pressing fixture to move forward automatically along the first fixed groove 601.

[0050] Preferably, an elastic buffer is provided between the mounting plate 1 and the pressing structure 4. The elastic buffer can be a spring. Specifically, the pressing wheel 6 is rotatably mounted on the fixing block, and the fixing block is mounted on the mounting plate 1 by the spring. In this way, when the mounting plate 1 drives the pressing wheel 6 downward to abut against the rubber strip 701, the spring can partially contract, providing a buffering effect for the pressing wheel 6. It should be noted that in order to ensure that the pressing wheel 6 can apply pressure to the rubber strip 701, a spring with relatively high hardness needs to be selected.

[0051] In one specific embodiment, this application provides a driving device, which may be a cylinder. The pressing wheel 6 is located at the end of the driving device. The driving device can drive the pressing wheel 6 to move up and down to adjust the height of the pressing wheel 6. Specifically, when it is necessary to press the adhesive strip 701, the driving device drives the pressing wheel 6 to descend to a height lower than the limit wheel 5 and continuously ensures that each part of the adhesive strip 701 is pressed into the first fixing groove 601 one by one at this height.

[0052] In one specific implementation, the mounting plate 1 is provided with an elongated hole that is slidably connected to the pressing structure 4 for adjusting the installation height of the pressing structure 4. The height of the pressing structure 4 is adjusted by locking the pressing structure 4 into different positions of the elongated hole.

[0053] Preferably, the mounting plate 1 includes: a first mounting plate 101 for fixing the limiting structure 2 and the guide structure 3, and a second mounting plate 102 slidably connected to the first mounting plate 101 for fixing the pressing structure 4. Specifically, the first mounting plate 101 has a groove 1011 for the second mounting plate 102 to be inserted and slid. Multiple fixing holes are sequentially formed in the groove 1011. When the second mounting plate 102 slides to a predetermined position, the position of the second mounting plate 102 can be fixed by screws inserted into the fixing holes. Specifically, when the outer frame 6 of the chair back has a regular quadrilateral structure, the interval between the limiting structure 2, the guiding structure 3, and the pressing structure 4 can be increased. This allows the limiting structure 2 and the guiding structure 3 to straighten the rubber strip 701 in advance, preventing the rubber strip 701 from bending and hindering the movement of the pressing fixture during its forward movement, thus increasing the moving speed of the pressing fixture. When the outer frame 6 of the chair back has many irregular corners, the interval between the limiting structure 2, the guiding structure 3, and the pressing structure 4 needs to be decreased to prevent the limiting structure 2, the guiding structure 3, and the pressing structure 4 from failing to turn synchronously.

[0054] This application also provides a method for installing a chair back mesh fabric, the method comprising the following steps:

[0055] The first end of the adhesive strip 701, which surrounds the left, upper and right edges of the mesh fabric 7, passes sequentially through the limiting structure 2, the guide structure 3 and around the bottom of the pressing structure 4 of the chair back mesh fabric pressing fixture.

[0056] After the first end of the adhesive strip 701 passes through the chair back mesh fabric pressing fixture, the first end of the adhesive strip 701 is manually inserted into the starting position of the first fixing groove 601 of the outer frame 6 of the chair back.

[0057] The chair back mesh fabric pressing tool moves along the shape of the first fixing groove 601 and presses each part of the adhesive strip 701 into the first fixing groove 601 in sequence;

[0058] When the chair back mesh fabric pressing fixture moves to the end position near the first fixing groove 601, the chair back mesh fabric pressing fixture is taken out from the second end of the adhesive strip 701.

[0059] The second end of the adhesive strip 701 is manually inserted into the end of the first fixing groove 601;

[0060] Manually insert the lower side of the mesh fabric 7, which lacks the adhesive strip 701, into the second fixing groove 602 of the outer frame 6 of the chair back.

[0061] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of the invention and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of the invention should be included within the protection scope of the invention.
