Description

Technical Field

[0001] The utility model relates to the technical field of furniture, in particular to a quick-install chair. Background Art

[0002] Existing chairs are mostly fixed frame structures, which use mortise and tenon structures or screws to fasten the chair back, seat and legs together. After assembly, the structure of the chair is relatively fixed, which is inconvenient to carry, and it is relatively time-consuming and laborious for personnel to disassemble and assemble, and the practicality is poor. Utility Model Content

[0003] In order to solve the above technical problems, the purpose of the utility model is to provide a quick-assemble chair, which solves the problem of inconvenient assembly of existing chairs.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a quick-install chair, including a chair back, a seat and a side frame, the first end of the seat is hinged to the chair back, the side frame is located at the front and rear sides of the seat, the first end of the side frame is detachably connected to the chair back, the second end is provided with a matching portion, the second end of the seat is provided with a clamping portion, when the seat is rotated around the hinge with the chair back and unfolded into place, the clamping portion forms a clamping connection with the matching portion.

[0005] Furthermore, the side frame includes an armrest and a support leg arranged at one end of the armrest, the other end of the armrest is connected to the chair back, and the matching part is correspondingly arranged on the support leg.

[0006] By adopting the above technical solution, the matching part is arranged on the supporting leg, which facilitates the connection between the seat board and the supporting leg so as to adapt to the height of the seat board.

[0007] Furthermore, the matching part includes a protrusion arranged on the leg, one end of the clamping part is provided with a clamping socket that forms a clamping fit with the protrusion, and the other end of the clamping part is provided with a mounting hole to facilitate the screw connection between the clamping part and the leg.

[0008] By adopting the above technical solution, the setting of the mounting holes makes it convenient to screw the seat plate onto the legs after fasteners such as screws are passed through.

[0009] Furthermore, a groove cooperating with the bayonet is provided on the convex head, so as to limit the displacement of the clamping part along the axial direction of the convex head when the bayonet is clamped with the convex head.

[0010] By adopting the above technical solution and setting the groove, after the bayonet and the protrusion are connected, shaking between the seat plate and the legs in the horizontal direction is prevented, thereby improving the structural stability of the product after assembly.

[0011] Furthermore, a locking rod is hingedly connected to the lower end of the clamping portion on one side of the clamping port, a buckle is provided at the other end of the locking rod, and a clamping platform that forms a clamping fit with the buckle is provided on the other side of the clamping port.

[0012] By adopting the above technical solution, the setting of the locking rod can prevent the convex head from being separated from the opening part of the bayonet due to shaking or unexpected external force after the clamping part is clamped with the convex head through the bayonet. One end of the locking rod is hinged to one side of the bayonet, and the other side is buckled with the clamping convex through a buckle to close the opening part of the bayonet, thereby restricting the convex head in the bayonet, so as to improve the poor structural stability of the seat plate and the support leg after they are clamped with the convex head through the bayonet.

[0013] Furthermore, a mounting lug is provided at the connection between the chair back and the seat plate, and the end of the seat plate is correspondingly rotatably connected to the mounting lug.

[0014] By adopting the above technical solution, the installation lug is arranged to facilitate the connection between the lug and the seat plate, so that the seat plate can be folded onto the seat back in a state parallel to the side of the seat back after rotating around the hinge with the seat back.

[0015] Compared with the prior art, the advantages of the utility model are:

[0016] 1. In the utility model, one end of the seat panel is hinged to the chair back, and the other end is snap-fitted with the matching part on the side frame through the snap-fit ​​part. In this way, when assembling the chair, it is only necessary to pre-install the side frames on the front and rear sides of the chair back, and then flip the seat panel so that the snap-fit ​​part on the seat panel is snap-fitted with the matching part, so that the assembly of the chair can be completed quickly. Similarly, when disassembling, the snap-fitting state of the matching part can be separated first, and then the side frame can be separated from the chair back, so that the chair can be disassembled. The structure of the chair is simpler, and the seat panel is hinged to the chair back, which also reduces the relatively troublesome problem of carrying and assembling the separated chair back and seat panel.

[0017] 2. In the utility model, the two ends of the seat are respectively connected to the side frame and the chair back, and the chair back can provide comfort for people to sit and lean on. The seat and the side frame are connected by a clamping part and a matching part, and the other end of the seat is connected to the chair back, so that the two ends of the seat are stably limited, which helps to ensure the structural stability of the chair when it is unfolded and used.

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] Reference Figure 1 and 2 The chair includes a chair back 100, a seat plate 300 and a side frame. The seat plate 300 may be circular, rectangular or other shapes. A rectangular shape is taken as an example (for the convenience of description, the direction in the figure is Figure 2 As shown in the figure, the side frames are located at the front and rear sides of the seat plate 300, and the side frames include an armrest 200 and a leg 210. The leg 210 is arranged at the right end of the armrest 200, and the left end of the armrest 200 is connected to the front and rear sides of the chair back 100. The left end of the seat plate 300 is hinged at the middle position of the right side of the chair back 100. A clamping part is provided at the left end of the seat plate 300, and matching parts are provided at the adjacent sides of the two legs 210 corresponding to the matching parts, and a clamping connection is formed between the matching parts and the matching parts.

[0028] In this embodiment, a mounting lug can be provided on the right side of the chair back 100, and a slot is provided in the mounting lug. The left end of the seat plate 300 is correspondingly embedded in the slot, and the two are hinged after being penetrated by a pin or a shaft.

[0029] Specifically, refer to Figure 2 and 3 The clamping portion includes a clamping plate 320, the upper end of which is provided with a mounting hole 321, and the lower end is provided with a clamping socket 322, the bottom of which is in an open state, and the matching portion includes a protrusion 211 provided on the leg 210. When the seat 300 rotates around the hinge between it and the chair back 100 to be connected and combined with the leg 210, the clamping socket 322 of the clamping plate 320 is correspondingly clamped on the protrusion 211, thereby realizing the connection between the seat 300 and the leg 210, thereby completing the convenient assembly of the chair. When the chair is disassembled, the right end of the seat 300 can be lifted to fold it onto the chair back 100, and then the connection between the armrest 200 and the chair back 100 can be removed to complete the quick separation of the chair, which is simple and convenient.

[0030] Preferably, the convex head 211 protrudes from the surface of the support leg 210, and a groove 2110 is formed on the convex head 211, and the groove 2110 can be arranged in a circle on the convex head 211, and the groove pitch of the groove 2110 forms a clearance fit or an interference fit with the thickness of the clamping plate 320. When the clearance fit is used, it is relatively convenient to clamp and separate the two, and when the interference fit is used, the connection between the two is more stable, so that the seat plate 300 and the support leg 210 are more stable after being connected. When the clamping plate 320 is clamped with the groove 2110 through the bayonet 322, the front and rear direction of the clamping plate 320 (this direction is the axial direction of the convex head 211) is restricted, so that the seat plate 300 will not shake in the horizontal direction after being connected to the support leg 210, thereby improving the structural strength of the product.

[0031] In the above embodiment, the clip plate 320 is directly arranged on the front and rear sides of the right end of the seat plate 300. It can be imagined that a cross beam 310 can also be set at the right end of the seat plate 300, and the cross beam 310 is set between the two legs 210. The above-mentioned clip plate 320 is set at the front and rear ends to achieve the above-mentioned effect.

[0032] Based on the listed embodiment, the setting of the mounting hole 321 at the upper end of the snap-in plate 320 facilitates the use of screws to penetrate the mounting hole 321 and connect the leg 210, so as to enhance the structural stability of the chair after the seat 300 and the leg 210 are snap-fitted through the snap-in plate 320 and the protrusion 211.

[0033] In the above embodiment, the clip plate 320 is arranged on the seat 300 or the above-mentioned cross beam 310, and the protrusion 211 is arranged on the support leg 210. It can be imagined that the positions of the two can be interchanged, that is, the protrusion 211 is arranged on the seat 300 or the above-mentioned cross beam 310, and the clip plate 320 is arranged on the support leg 210 to achieve the above effect.

[0034] Based on the above embodiments, refer to Figure 4In order to facilitate the disassembly of the seat plate 300 and the leg 210 after the seat plate 300 and the leg 210 are connected by the clamping plate 320 and the protruding head 211, it is not necessary to use screws to penetrate the mounting hole 321 and the leg 210, and a locking rod 400 is provided at the clamping hole 322 of the clamping plate 320. One end of the locking rod 400 is hinged to one side of the clamping hole 322 of the clamping plate 320, and the other end is provided with a buckle 410. The other side of the clamping hole 322 is provided with a clamping platform 323 on the clamping plate 320. The clamping platform 323 A snap connection is formed between the snap buckle 410, so that when the snap plate 320 is snapped with the protrusion 211 through the snap slot 322, the locking rod 400 is rotated to make the snap buckle 410 snapped with the clamping platform 323, and then the protrusion 211 is locked in the snap slot 322, so that the snap plate 320 and the protrusion 211 are locked in the vertical direction. When it is necessary to release the snap connection between the snap plate 320 and the protrusion 211, the snap buckle 410 can be separated from the clamping platform 323 by external force, and then the open part of the snap slot 322 can be opened to allow the protrusion 211 to separate from the snap slot 322.

[0035] In this embodiment, the embodiment of the locking rod 400 can be used together with the solution of screws penetrating the mounting hole 321 and the supporting leg 210 , thereby effectively enhancing the connection strength between the seat plate 300 and the supporting leg 210 .

[0036] In this embodiment, the locking rod 400 preferably adopts an arc-shaped structure to adapt to the surface of the fitting groove 2110, thereby improving the fit and locking stability when the two are fastened, and the locking rod 400 can be made of metal, which has a certain elastic bending ability, so that when the personnel push the buckle 410 to separate from the card platform 323, the elastic bending of the metal can be used to achieve convenient separation of the buckle 410 and the card platform 323. Of course, the locking rod 400 can also be set not to be elastic, as long as the convenient connection and separation between the buckle 410 and the card platform 323 can be easily completed, and at the same time, the two have a certain fastening force after being connected. Either the buckle 410 or the card platform 323 can also be set to be elastic, so that personnel can use external force to push the buckle 410 to separate from the card platform 323.

[0037] Although the preferred embodiments of the present invention are described in detail above, it should be clearly understood that the present invention may be modified and varied by those skilled in the art. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
