Description

Technical Field

[0001] The present application relates to the technical field of office furniture, and more specifically to a mesh installation structure for a seat and a seat. Background Art

[0002] Currently, in order to improve breathability and heat dissipation, seats mostly use mesh in combination with the backrest frame or the seat frame of the seat as the backrest or seat of the seat. The breathable mesh is used as a fabric to wrap around the backrest frame or the seat frame, without the need for fillers, and has characteristics such as environmental protection, breathability, and health. Moreover, it has a high degree of softness and comfort, is suitable for long-term office use, and mesh seats also have advantages such as material saving and cost reduction. The existing installation methods of the mesh are mostly as follows: a groove is recessed along the periphery of the backrest frame or the seat frame. After the mesh is tightened on the backrest frame or the seat frame, the four sides of the mesh are clamped and pressed into the groove, and each section of the mesh is fixed in the groove with screws or pins, so that the mesh is fixed on the seat frame or the backrest frame in a tightened state. This installation method is cumbersome and laborious on the one hand, and on the other hand, the mesh is prone to looseness or even detachment after long-term use, especially it is difficult to disassemble and replace the mesh after installation, and the user experience is poor. To solve the foregoing problems, for example, the utility model patent with the publication (announcement) number: CN203692983U discloses a steel frame mesh chair, including a backrest and a seat. Both the backrest and the seat are composed of a frame and a mesh. The frame includes side frames on both sides and connecting components at the four corners; the side frames include an integrally formed inner tube and an outer tube, and the connection between the inner tube and the outer tube is a smooth transition; a frame opening is jointly provided on the tube walls of the inner tube and the outer tube, and the frame opening extends from the top to the bottom of the frame; the connecting component includes a hollow cylinder, which is horizontally installed at the top and bottom of the side frame, and a slot is provided on the side wall of the cylinder, and the slot is aligned with the frame opening; rubber strips are fixed on both sides of the mesh; the rubber strips are clamped in the inner tube, and the mesh passes through the opening of the frame; the upper and lower parts of the mesh are fixed on the connecting component; during installation, the rubber strips are sleeved into the channels on both sides of the mesh, and then the rubber strips fixed on the mesh are inserted into the slots of the connecting piece, and then the mesh is pulled down to form a seat. During disassembly, the mesh can be pulled up or down to remove the mesh, and then the rubber strips can be pulled out of the channels, thus realizing the disassembly and assembly of the mesh. However, it is difficult to conveniently adjust the tightness state of the mesh in this solution. When the mesh is used until it is loose and deformed, it is difficult to conveniently and labor-savingly adjust the mesh to be tightened, so that the loose and deformed mesh can only be disassembled and reinstalled or directly replaced with a new mesh, reducing the user experience. Therefore, there is still a need for a mesh installation structure that can not only be disassembled and assembled but also adjust the tightening force. Summary of the Invention

[0003] The technical problem to be solved by the present application is to provide a mesh installation structure for a seat and a seat. This mesh installation structure can not only realize the disassembly and assembly of the mesh, but also adjust the tightening force of the mesh to meet more usage requirements.

[0004] The present application provides a net cloth installation structure for a seat, including a regulator and a connecting rope. The connecting rope is used to surround and penetrate the net cloth and connect with the regulator. The regulator includes a housing, a winding wheel, and a rotating cover. The rotating cover is rotatably installed on the housing. The winding wheel is installed in the housing and connected to the rotating cover. The housing is provided with an opening for the connecting rope to enter and exit. The connecting rope passes through the opening and is wound around the winding wheel. The rotating cover drives the winding wheel to rotate bidirectionally under force, and the winding wheel winds and unwinds the connecting rope by rotating bidirectionally. In this technical solution, the net cloth is limited on the seat frame by surrounding the net cloth along the frame border of the seat with the connecting rope. The tightness of the connecting rope is adjusted by the regulator. The regulator is provided with an opening in the housing so that the connecting rope can pass through the opening and enter the housing and then be wound around the winding wheel. The winding wheel can wind and unwind the connecting rope by rotating, so that the net cloth can be disassembled and assembled on the seat frame, and the tightness of the net cloth on the seat frame can also be adjusted to meet more usage requirements. By providing a rotating cover connected to the winding wheel, the user applies force to the rotating cover to make it rotate, and the rotating cover drives the winding wheel to rotate synchronously, thereby realizing the winding and unwinding of the connecting rope. The rotation is labor-saving and simple to use, and the overall structure of the regulator is simple and reliable.

[0005] As an improvement, the rotating cover is sleeved with the housing. The rotating cover moves telescopically relative to the housing under force and drives the winding wheel to move synchronously, so that the winding wheel moves to a position where the connecting rope is tightened or a position where the connecting rope is relaxed. In this technical solution, the rotating cover is sleeved with the housing. The rotating cover can not only rotate on the housing but also move telescopically relative to the housing. The rotating cover is connected to the winding wheel and can drive the winding wheel to move synchronously. The user pulls out or presses the rotating cover to make the winding wheel slide synchronously in the housing, so that the winding wheel can slide and switch between connecting a first one-way rotation mechanism and a second one-way rotation mechanism. The structural design is ingenious and the switching is labor-saving and reliable.

[0006] As an improvement, a first one-way rotation mechanism is provided between the housing and the winding wheel. The rotary cover drives the winding wheel to move to connect or disengage from the first one-way rotation mechanism. When the winding wheel moves to the position where the connecting rope is tightened, the winding wheel rotates in the first direction through the first one-way rotation mechanism to tighten the connecting rope. In this technical solution, by setting the first one-way rotation mechanism, the winding wheel is restricted to rotate only in one direction, which is the direction of tightening the connecting rope. The winding wheel is connected to the first one-way rotation mechanism so that the regulator can only tighten the connecting rope, which can further improve the tightening force of the connecting rope and the tightening force of the connecting rope on the mesh fabric, so that the mesh fabric is not easily loosened or even disengaged, improving the reliability of use. And by driving the winding wheel to move with the rotary cover, the winding wheel can be switched to connect or disengage from the first one-way rotation mechanism. When the winding wheel moves away from the first one-way rotation mechanism, the one-way rotation lock can be released. The winding wheel can not only tighten the connecting rope but also loosen the connecting rope through two-way rotation, thus meeting more usage experience.

[0007] As an improvement, a second one-way rotation mechanism is provided between the housing and the winding wheel. The rotary cover drives the winding wheel to move to connect or disengage from the second one-way rotation mechanism. When the winding wheel moves to the position where the connecting rope is relaxed, the winding wheel rotates in the second direction through the second one-way rotation mechanism to relax the connecting rope. In this technical solution, by setting the second one-way rotation mechanism, the winding wheel is restricted to rotate only in the second direction, which is the direction of loosening the connecting rope. The second direction is opposite to the first direction. The winding wheel is connected to the second one-way rotation mechanism so that the regulator can only loosen the connecting rope, thus avoiding the mesh fabric from being too tight due to the action of the connecting rope. Moreover, after the mesh fabric is installed, it can be disassembled and replaced by loosening the connecting rope, and its tension adjustment is more reliable, meeting more usage requirements. And by driving the winding wheel to move with the rotary cover, the user can pull out or press the rotary cover to make the winding wheel slide synchronously in the housing, so that the winding wheel can be switched to connect the first one-way rotation mechanism and the second one-way rotation mechanism by sliding. Optionally, the winding wheel can be connected to the first one-way rotation mechanism and disengaged from the second one-way rotation mechanism, or the winding wheel can be connected to the second one-way rotation mechanism and disengaged from the first one-way rotation mechanism. The winding wheel always rotates in one direction, improving the reliability of use of the regulator.

[0008] As an improvement, the first unidirectional rotating mechanism includes a first rotating member and a first ratchet, the first rotating member is detachably connected to the winding wheel, the first ratchet is connected to the shell, and the first rotating member is meshed with the first ratchet. In this technical solution, the winding wheel can be switched to be connected or disengaged with the first unidirectional rotating mechanism, and the first unidirectional rotating mechanism is connected to the shell through the first ratchet and to the winding wheel through the first rotating member. When the winding wheel is rotated by force, the winding wheel drives the first rotating member to rotate along the first ratchet, and the first rotating member cooperates with the first ratchet so that the winding wheel can only rotate in the first direction. The first rotating member is detachably connected to the winding wheel, and the winding wheel can release the unidirectional rotation restriction by movably disengaging from the first rotating member. The structural design is ingenious and reliable.

[0009] As an improvement, the winding wheel is provided with a first convex tooth, the first rotating member is provided with a first limiting groove adapted to the first convex tooth, a plurality of the first limiting grooves are evenly spaced along the circumference of the first rotating member, and the winding wheel is connected to or separated from the first limiting groove through the first convex tooth so as to be detachably connected to the first rotating member. In this technical solution, by providing a first convex tooth on the winding wheel and a first limiting groove on the first rotating member, and connecting the first convex tooth with the first limiting groove, the winding wheel and the first rotating member can be rotated synchronously, and by providing a plurality of first limiting grooves evenly spaced along the circumference of the first rotating member, the winding wheel rotates after being separated from the first rotating member, and the first convex tooth can still correspond to other first limiting grooves, so that the subsequent first convex tooth and the first limiting groove can be reconnected and limited, and the structural design is ingenious and reliable to use.

[0010] As an improvement, the second one-way rotating mechanism includes a second rotating member and a second ratchet, the second rotating member is detachably connected to the winding wheel, the second ratchet is connected to the shell, and the second rotating member is meshed with the second ratchet. In this technical solution, the winding wheel can be switched to be connected or disengaged with the second one-way rotating mechanism, and the second one-way rotating mechanism is connected to the shell through the second ratchet and to the winding wheel through the second rotating member. When the winding wheel is rotated by force, the winding wheel drives the second rotating member to rotate along the second ratchet, and the second rotating member cooperates with the second ratchet so that the winding wheel can only rotate in the second direction. The second rotating member is detachably connected to the winding wheel, and the winding wheel can release the one-way rotation restriction by movably disengaging from the second rotating member. The structural design is ingenious and reliable.

[0011] As an improvement, the winding wheel is provided with a second convex tooth, the second rotating member is provided with a second limiting groove adapted to the second convex tooth, and the second limiting groove is provided with a plurality of them along the circumference of the second rotating member. The winding wheel is connected or separated from the second limiting groove through the second convex tooth to be separably connected with the second rotating member. In this technical solution, by providing a second convex tooth on the winding wheel and a second limiting groove on the second rotating member, and connecting the second convex tooth with the second limiting groove, the winding wheel can be made to rotate synchronously with the second rotating member. By providing a plurality of second limiting grooves distributed along the circumference of the second rotating member, the winding wheel rotates after being separated from the second rotating member, and the second convex tooth can still correspond to other second limiting grooves, so that the subsequent second convex tooth and the second limiting groove can be reconnected and limited, and the structural design is ingenious and reliable in use; on the other hand, the first convex tooth and the second convex tooth are respectively located on the two side end faces of the winding wheel, and the winding wheel switches the connection between the first rotating member and the second rotating member by moving back and forth, and the structural design saves more space and is conducive to reducing the overall size.

[0012] As an improvement, one end of the shell is connected to a rotary cover, and the other end of the shell is connected to a bottom cover, the first ratchet is arranged on the bottom cover, and the second ratchet is arranged on the inner wall of the shell.

[0035] Example 1

[0036] Such as Figures 1 to 8As shown in the figure, the present application discloses a mesh installation structure for a seat, which includes a regulator 1 and a connecting rope 2. The connecting rope 2 is used to surround and pass through the mesh and connect with the regulator 1. The connecting rope 2 surrounds the mesh along the frame 3 of the seat, thereby limiting the mesh on the frame 3, and the tightness of the connecting rope 2 is adjusted by the regulator 1. The regulator 1 includes a housing 11, a winding wheel 12 and a rotary cover 13. The rotary cover 13 is rotatably installed on the housing 11, the winding wheel 12 is installed in the housing 11 and connected with the rotary cover 13. The housing 11 is provided with an opening 111 for the connecting rope 2 to enter and exit. The connecting rope 2 passes through the opening 111 and is wound around the winding wheel 12. The rotary cover 13 drives the winding wheel 12 to rotate bidirectionally by applying force. The winding wheel 12 winds and unwinds the connecting rope 2 by rotating bidirectionally. The regulator 1 is provided with the opening 111 through the housing 11, so that the connecting rope 2 can pass through the opening 111 and enter the housing 11 and then can be wound around the winding wheel 12. The winding wheel 12 can wind and unwind the connecting rope 2 by rotating, so that the mesh can be disassembled and assembled on the frame 3, and the tightness of the mesh on the frame 3 can also be adjusted to meet more usage requirements. By setting the rotary cover 13 connected with the winding wheel 12, the user applies force to the rotary cover 13 to make the rotary cover 13 rotate, and drives the winding wheel 12 to rotate synchronously through the rotary cover 13, thereby realizing the winding and unwinding of the connecting rope 2. The rotation is labor-saving and simple to use, and the overall structure of the regulator 1 is simple and reliable.

[0037] More specifically, as Figure 2 and Figure 3 shown, the rotary cover 13 is sleeved on the housing 11. The rotary cover 13 moves telescopically relative to the housing 11 under force and drives the winding wheel 12 to move synchronously, so that the winding wheel 12 moves to the position where the connecting rope 2 is tightened or the position where the connecting rope 2 is relaxed. The rotary cover 13 is sleeved on the housing 11. The rotary cover 13 can not only rotate on the housing 11, but also move telescopically relative to the housing 11. The rotary cover 13 is connected with the winding wheel 12 so as to be able to drive the winding wheel 12 to move synchronously. The user pulls out or presses the rotary cover 13 to make the winding wheel 12 slide synchronously in the housing 11, so that the winding wheel 12 moves to the position where the connecting rope 2 is tightened or the position where the connecting rope 2 is relaxed.

[0038] More specifically, as Figure 3 and Figure 6As shown, a first one-way rotation mechanism is provided between the housing 11 and the winding wheel 12. The rotary cover 13 drives the winding wheel 12 to move to connect or disengage from the first one-way rotation mechanism. When the rotary cover 13 drives the winding wheel 12 to move to connect the first one-way rotation mechanism, the winding wheel 12 moves to the position where the connecting rope 2 is tightened. The winding wheel 12 rotates in the first direction through the first one-way rotation mechanism to tighten the connecting rope 2. By setting the first one-way rotation mechanism, it is restricted that the winding wheel 12 can only rotate unidirectionally in the first direction, and this first direction refers to the direction of tightening the connecting rope 2. When the winding wheel 12 connects the first one-way rotation mechanism, the adjuster 1 can only tighten the connecting rope 2, which can further improve the tightening force of the connecting rope 2 and the tightening force of the connecting rope 2 on the mesh fabric, so that the mesh fabric is not easily loosened or even disengaged, improving the use reliability. And by driving the winding wheel 12 to move through the rotary cover 13, the winding wheel 12 can be switched to connect or disengage from the first one-way rotation mechanism. When the winding wheel 12 moves to disengage from the first one-way rotation mechanism, the one-way rotation lock can be released. The winding wheel 12 can not only tighten the connecting rope 2 but also loosen the connecting rope 2 through bidirectional rotation, thus meeting more usage experience feelings.

[0039] More specifically, as Figure 3 and Figure 7 shown, a second one-way rotation mechanism is provided between the housing 11 and the winding wheel 12. The rotary cover 13 drives the winding wheel 12 to move to connect or disengage from the second one-way rotation mechanism. When the rotary cover 13 drives the winding wheel 12 to move to connect the second one-way rotation mechanism, the winding wheel 12 moves to the position where the connecting rope 2 is relaxed. The winding wheel 12 rotates in the second direction through the second one-way rotation mechanism to relax the connecting rope 2. By setting the second one-way rotation mechanism, it is restricted that the winding wheel 12 can only rotate unidirectionally in the second direction, and this second direction refers to the direction of loosening the connecting rope 2, and the second direction is opposite to the first direction. When the winding wheel 12 connects the second one-way rotation mechanism, the adjuster 1 can only loosen the connecting rope 2, so as to avoid the mesh fabric being too tight due to the action of the connecting rope 2. Moreover, after the mesh fabric is installed, it can be disassembled and replaced by loosening the connecting rope 2, and its tightening force adjustment is more reliable, meeting more usage requirements. And by driving the winding wheel 12 to move through the rotary cover 13, the user pulls out or presses the rotary cover 13 to make the winding wheel 12 slide synchronously in the housing 11, so that the winding wheel 12 switches to connect the first one-way rotation mechanism and the second one-way rotation mechanism by sliding. Optionally, the winding wheel 12 connects the first one-way rotation mechanism and disengages from the second one-way rotation mechanism, or the winding wheel 12 connects the second one-way rotation mechanism and disengages from the first one-way rotation mechanism. The winding wheel 12 always rotates unidirectionally, improving the use reliability of the adjuster 1. The structural design is ingenious and the switching is labor-saving and reliable.

[0040] More specifically, as Figure 3 、 Figure 4 、 Figure 6 andFigure 7 As shown, the first one-way rotating mechanism includes a first rotating member 14 and a first ratchet 15. The first rotating member 14 is detachably connected to the winding wheel 12, the first ratchet 15 is connected to the shell 11, the first rotating member 14 is meshed with the first ratchet 15, and the winding wheel 12 can be switched to be connected or disconnected with the first one-way rotating mechanism. The first one-way rotating mechanism is connected to the shell 11 through the first ratchet 15, and is connected to the winding wheel 12 through the first rotating member 14. When the winding wheel 12 is rotated under force, the winding wheel 12 drives the first rotating member 14 to rotate along the first ratchet 15. The first rotating member 14 cooperates with the first ratchet 15 so that the winding wheel 12 can only rotate in a first direction. The first rotating member 14 is detachably connected to the winding wheel 12, and the winding wheel 12 can be separated from the first rotating member 14 by movement to release the one-way rotation restriction. The structural design is ingenious and reliable.

[0041] More specifically, Figure 3 and Figure 4 As shown, the winding wheel 12 is provided with a first convex tooth 121, and the first rotating member 14 is provided with a first limiting groove 141 adapted to the first convex tooth 121. A plurality of first limiting grooves 141 are evenly spaced along the circumference of the first rotating member 14. The winding wheel 12 is connected to or separated from the first limiting groove 141 through the first convex tooth 121 to be detachably connected to the first rotating member 14. By providing the first convex tooth 121 on the winding wheel 12 and the first limiting groove 141 on the first rotating member 14, By connecting the first protruding tooth 121 with the first limiting groove 141, the winding wheel 12 can be made to rotate synchronously with the first rotating member 14. By setting a plurality of first limiting grooves 141 evenly spaced along the circumference of the first rotating member 14, the winding wheel 12 rotates after being separated from the first rotating member 14, and the first protruding tooth 121 can still correspond to other first limiting grooves 141, so that the subsequent first protruding tooth 121 and the first limiting groove 141 can be reconnected and limited. The structural design is ingenious and reliable to use.

[0042] More specifically, Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the second one-way rotating mechanism includes a second rotating member 16 and a second ratchet 17. The second rotating member 16 is detachably connected to the winding wheel 12, the second ratchet 17 is connected to the housing 11, the second rotating member 16 is meshed with the second ratchet 17, and the winding wheel 12 can be switched to be connected to or disconnected from the second one-way rotating mechanism. The second one-way rotating mechanism is connected to the housing 11 through the second ratchet 17 and to the winding wheel 12 through the second rotating member 16. When the winding wheel 12 is rotated under force, the winding wheel 12 drives the second rotating member 16 to rotate along the second ratchet 17. The second rotating member 16 cooperates with the second ratchet 17 so that the winding wheel 12 can only rotate in the second direction. The second rotating member 16 is detachably connected to the winding wheel 12, and the winding wheel 12 can be disengaged from the second rotating member 16 by movement to release the one-way rotation restriction. The structural design is ingenious and reliable.

[0043] More specifically, Figure 3 and Figure 4 As shown, the winding wheel 12 is provided with a second convex tooth 122, and the second rotating member 16 is provided with a second limiting groove 161 adapted to the second convex tooth 122. A plurality of second limiting grooves 161 are provided along the circumference of the second rotating member 16. The winding wheel 12 is connected to or separated from the second limiting groove 161 through the second convex tooth 122 so as to be detachably connected with the second rotating member 16. By providing the second convex tooth 122 on the winding wheel 12 and the second limiting groove 161 on the second rotating member 16, and connecting the second convex tooth 122 with the second limiting groove 161, the winding wheel 12 and the second rotating member 16 can be made to rotate synchronously. There are multiple second limiting grooves 161 distributed along the circumference of the second rotating member 16.
