Description

Technical Field

[0001] The utility model relates to an outdoor fixed chair, in particular to an outdoor fixed chair seat surface expansion piece and the outdoor fixed chair with the expansion piece. Background Art

[0002] The outdoor fixed chair includes a seat assembly and a leg assembly. The leg assembly is fixed on the ground. The seat assembly is assembled and fixed with the leg assembly. The seat assembly includes a seat and fixed parts connected and fixed to both sides of the seat assembly. The outdoor fixed chair can be renovated by replacing the entire seat assembly. In order to facilitate the separate storage and transportation of the seat assembly, the volume of the seat assembly during storage will be reduced. The tubular fixed parts on both sides of the seat are usually independent of each other and not connected to each other. There are no connecting pipes or other components welded or bolted between the tubular fixed parts on both sides, resulting in the defect that the tension of the seat is difficult to adjust to the set value.

[0003] A Chinese patent with application number 202221335575.5 discloses an outdoor fixed chair, including a seat assembly and a chair leg assembly, the seat assembly being used to be assembled and installed with the chair leg assembly, the seat assembly including side tubes located on both sides and a seat body connected between the side tubes, the seat assembly also including a seat support member, the seat support member including a support tube and an external expansion member, one end of the support tube is provided with a docking end that cooperates with a docking hole on one side of the side tube, the other end of the support tube is an assembly end and is threadedly engaged with the external expansion member, by moving the external expansion member axially along the support tube and contacting the other side tube, the distance between the two side tubes is adjusted to a set value, and the expansion and tension adjustment of the seat are realized.

[0004] When assembling the seat support parts of the above scheme, the assembler needs to limit the rotation of the support tube with one hand and rotate the expansion part with the other hand. The assembler needs to hold the support tube and the expansion part firmly, which makes the assembly more troublesome and laborious. If nut structures are provided on both the support tube and the expansion part, the assembler needs to use tools such as wrenches during assembly. Utility Model Content

[0005] The utility model aims to provide a seat surface stretching component for an outdoor fixed chair, which is convenient for adjusting the distance between the fixed parts on both sides of the seat surface to a set value and convenient for realizing the tensioning of the seat surface.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a seat support member for an outdoor fixed chair, including docking ends located on both sides and used to support and contact the fixed parts of the seat on opposite sides, the two docking ends are respectively arranged at one end of a first support member monomer and one end of a second support member monomer, the other end of the first support member monomer is rotatably connected to the deviated end of the second support member monomer, and the other end of the second support member monomer and the deviated end of the first support member monomer are provided with a locking structure that cooperates with each other to maintain the relative position between the first support member monomer and the second support member monomer.

[0007] When it is necessary to assemble the seat surface assembly and the chair leg assembly, the seat surface assembly can be unfolded first, and then the two ends of the expansion piece of the utility model can be docked with a fixed part of the seat surface assembly respectively, so that the docking end of the first expansion piece monomer and the docking end of the second expansion piece monomer are docked with a fixed part respectively, and the cross-overlapping part of the first expansion piece monomer and the second expansion piece monomer is pressed to achieve the relative rotation of the first expansion piece monomer and the second expansion piece monomer. When the locking structures can cooperate with each other, it means that the adjustment is in place. Finally, the locking structure can be locked. The expansion piece can be installed in place at one time. Even ordinary people can install the expansion piece. No professional assembly workers are required to install it. It is convenient to adjust the distance between the fixed parts on both sides of the seat surface to the set value, and it is convenient to achieve tensioning of the seat surface.

[0008] The first and second expansion member monomers of the utility model can be made of rod-shaped members or tubular members. When the first and second expansion member monomers are relatively rotated, only the first and second expansion member monomers need to be pressed at the intersection and overlap, so there is no need to rotate the first and second expansion member monomers, which can make the assembly of the expansion member more convenient and labor-saving.

[0009] At the same time, since there is no need to hold the first stretching member monomer and the second stretching member monomer all the time, and when the first stretching member monomer and the second stretching member monomer cross, the middle part of the stretching member of the utility model is closer to the chair surface and can be inserted with fingers, the utility model can make the stretching member closer to the chair surface after assembly while ensuring convenient assembly, and there is no need to make the distance between the stretching member and the chair surface after assembly for fingers to pass through, so that it can be suitable for chair surface components with thinner fixed parts and smaller volume.

[0010] The docking method of the support member of the utility model and the fixed part of the chair seat assembly can adopt the plug-in connection of a conventional outdoor fixed chair, that is, a hole or a groove is formed on one component, and an end protrusion for extending into the hole or the groove is formed on the other component. Any existing structure for outdoor fixed chairs that can achieve alignment and positioning between the two components can also be adopted.

[0011] The locking structure of the utility model can be a conventional locking structure, or a bolt locking structure, a buckle locking structure, or the like, which can realize a detachable fixation between two components.

[0012] Preferably, the locking structure comprises a locking hole provided on the first expansion member and a locking pin matched with the second expansion member, the locking pin is matched with a locking nut or the outer wall of the locking pin and the wall of the locking hole are provided with a threaded structure that matches each other.

[0013] The utility model adopts a bolt locking structure, which can reduce the production cost while ensuring convenient assembly, and at the same time ensure stability after assembly; and the locking pin and the locking hole are easier to match and align. A bolt-style locking pin can be used, and an internal threaded hole can be machined on the wall of the locking hole; or the length of the locking pin can be increased so that the locking pin can pass through the locking hole and match with the locking nut. Among them, the axial movement direction of the locking pin forms an angle with the expansion member, and the rotation of the locking pin does not affect the rotation between the first expansion member monomer and the second expansion member monomer. The locking pin only needs to be inserted into the locking hole, which can make the force required for the rotation of the locking pin smaller.

[0014] Preferably, one end of the locking pin for extending into the locking hole has a tapered section, or the end of the locking hole is open.

[0015] By machining a cone at one end of the locking pin, or machining an open shape at the end of the locking hole, adaptive alignment can be achieved by roughly aligning the locking pin with the locking hole and then rotating the locking pin, making the assembly of the propping member of the utility model more convenient.

[0016] Preferably, the end of the locking pin not used for extending into the locking hole has a knob.

[0017] By providing a knob at the other end of the locking pin, it is convenient for an assembler to hold and rotate the locking pin, thereby facilitating locking and matching.

[0018] Preferably, the second expansion member monomer is provided with a fixing block away from its docking end, and when the locking structure between the first expansion member monomer and the second expansion member monomer cooperates, the fixing block approaches the first expansion member monomer or the fixing block contacts the first expansion member monomer.

[0019] By making the fixed block contact or close to the first expansion member monomer, the rotation angle between the first expansion member monomer and the second expansion member monomer is limited, and the cooperation of the locking structure is facilitated. The alignment of the locking structure can be achieved by simply rotating the first expansion member monomer and the second expansion member monomer to the limit angle.

[0020] Preferably, the first opening member monomer and the second opening member monomer both include a first straight section, a connecting section and a second straight section, the connecting section is located between the first straight section and the second straight section, and the extension direction of the first straight section and the extension direction of the second straight section are not on the same straight line, the docking ends are both arranged on the first straight section, and the second straight section of the first opening member monomer is rotatably connected with the second straight section of the second opening member monomer.

[0021] By tilting or bending the connecting section, the front and rear ends of the connecting section are connected to the first straight section and the second straight section respectively. After the expansion member and the seat surface assembly are assembled, the first straight section is closer to the seat surface, and the second straight section is farther away from the seat surface. In the case where the fixed part is thin, the intersection and overlap of the first expansion member monomer and the second expansion member monomer can be farther away from the seat surface, which is more convenient for the assembler to hold and install, and the assembly of the expansion member can be more convenient.

[0022] The utility model also discloses a fixed chair with the above-mentioned outdoor fixed chair seat cover extension member, including a seat cover, which is located between two relatively fixed parts, and the seat cover includes a cushion part and a backrest part. At least the fixed part corresponding to the lower side of the cushion part or corresponding to the rear side of the backrest part is provided with a matching structure for matching with the docking end of the outdoor fixed chair seat cover extension member.

[0023] The expansion piece of the utility model can be arranged on the lower side of the cushion part of the chair surface or the rear side of the backrest part according to actual needs. The space under the cushion part of the chair surface is narrow. The solution of the utility model can make the assemblers spend less time lying down or squatting when assembling the chair surface assembly and the chair leg assembly, which can make the assembly of the outdoor fixed chair more convenient. The expansion piece of the utility model is arranged at the backrest part which is relatively deviated from the chair leg assembly. The expansion piece can be used to achieve the connection of the fixed part of the backrest part to improve the structural strength of the chair surface assembly. Among them, the outdoor fixed chair of the utility model can only use the expansion piece of the utility model, and can also be used in combination with any expansion piece of the existing outdoor fixed chair to expand the chair surface and connect the fixed parts of the chair surface assembly.

[0024] Preferably, the matching structure is provided at the fixing portion corresponding to the lower side of the cushion portion and the rear side of the backrest portion.

[0025] The lower side and the rear side of the seat surface of the outdoor fixed chair of the utility model are both provided with the propping-up members of the utility model, which can not only make all parts of the seat surface propped up, but also improve the structural strength of the seat surface assembly of the utility model.

[0026] Preferably, the matching structure is a connecting hole with a side opening arranged on the fixed part, and when the seat support member of the outdoor fixed chair matches with the fixed part, the docking end of the first support member monomer and the docking end of the second support member monomer respectively extend into a docking hole of a fixed part.

[0027] The way in which the docking holes and the docking ends are plugged into each other can reduce the production cost of the seat assembly of the outdoor fixed chair of the utility model, and can well ensure the stability of the two ends of the support member, preventing the support member from deviating from the rotation direction of the first support member monomer and the second support member monomer, thereby ensuring assembly stability.

[0028] Preferably, the first expansion member monomer and the second expansion member monomer are both provided with limiting protrusions near the butt ends, and when the butt ends are extended into the butt holes, the limiting protrusions are in contact with or close to the fixing parts.

[0029] By setting a limiting protrusion, excessive rotation between the first and second support member monomers can be avoided, the distance between the two ends of the support member after adjustment can be ensured, and then the distance between the two fixed parts of the seat surface assembly can be ensured to be the set value, so that the tension of the seat surface can reach the set requirements.

[0030] The utility model has the advantages of being easy to assemble, easy to adjust the distance between the fixed parts on both sides of the chair surface to a set value, and easy to achieve the tensioning of the chair surface. BRIEF DESCRIPTION OF THE DRAWINGS
