Description

Technical Field

[0001] The utility model relates to the technical field of solid wood chairs, in particular to a solid wood chair that is pressure-resistant and not easily deformed. Background Art

[0002] Solid wood furniture refers to furniture in which all wooden parts (except mirror trays and moldings) are made of solid sawn wood or solid wood boards. That is to say, the main body of the furniture is made of pure natural wood, and the back panel or bottom layer of the furniture is supplemented by some materials such as plywood. Solid wood veneer furniture refers to furniture in which the base material is made of solid sawn wood or solid wood boards, and the surface is covered with solid wood veneer or thin wood (veneer).

[0003] Existing solid wood chairs are generally assembled by gluing or mortise and tenon structures. The assembly joints of solid wood chairs are relatively fragile, and the strength of the entire solid wood chair is not high. When the solid wood chair is subjected to pressure, the stability of the joints of the solid wood chair will be affected. Since users will also move and squeeze laterally when riding on the solid wood chair, the solid wood chair is prone to shaking and instability after being used for a period of time. Utility Model Content

[0004] The purpose of the utility model is to provide a solid wood chair that is resistant to pressure and not easy to deform. The solid wood chair is assembled by an integrated support frame and a seat plate. When people sit on the chair, the force points are concentrated on the connection between the chair legs, which improves the situation in which the connection between the chairs is easily loosened due to the shaking of traditional solid wood chairs, and effectively improves the strength of the solid wood leisure chair.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a pressure-resistant and non-deformable solid wood chair, comprising rear support legs, front support legs fixed to the surface of the rear support legs, and a top rod fixed between the rear support legs, and further comprising:

[0006] A transverse fixing rod fixed between the rear supporting legs, a longitudinal connecting rod fixed between the rear supporting legs and the front supporting legs, and a seat plate movably connected between the rear supporting legs and the front supporting legs, an auxiliary mounting plate fixed between the rear supporting legs and the front supporting legs, and the seat plate located above the auxiliary mounting plate;

[0007] A backrest is fixed to the bottom of the top rod, and connecting columns are fixed to both sides of the backrest. The connecting columns are fixedly connected to the rear supporting legs.

[0008] Preferably, the backrest adopts an arc-shaped design and is located at the center of the top rod.

[0009] Preferably, a fitting groove is provided on the top of the seat plate and a plurality of anti-slip strips are fixed inside the fitting groove.

[0010] Preferably, the bottoms of the front supporting legs and the rear supporting legs are both covered with buffer sleeves, and the buffer sleeves are made of rubber material.

[0011] Preferably, a plurality of ventilation holes are provided on the surface of the backrest, and cushions are fixed on both sides of the backrest surface.

[0012] Preferably, a reinforcing rod is fixed to the inner side of each of the front supporting legs and the rear supporting legs, and the other end of the reinforcing rod is fixedly connected to the surface of the auxiliary mounting plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] The utility model adopts an integrated support frame and a seat plate to be installed in combination. When people sit on the chair, the force points are concentrated on the connection between the chair legs, which improves the problem that the shaking of traditional solid wood chairs easily leads to loose connections between the chairs, effectively improves the strength of the solid wood leisure chair, and solves the problem that the existing solid wood chairs are not strong enough and the stability of the connection of the solid wood chairs will be affected when the solid wood chairs are subjected to pressure. Since users will also move and squeeze laterally when sitting on the solid wood chairs, the solid wood chairs are prone to shaking and instability after being used for a period of time.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-4 As shown, a solid wood chair that is resistant to pressure and not easy to deform comprises a rear supporting leg 1, a front supporting leg 15 and a top rod 2. The front supporting leg 15 is fixed to the surface of the rear supporting leg 1, and the top rod 2 is fixed between the rear supporting legs 1. A horizontal fixing rod 3 is fixed between the rear supporting legs 1, and a longitudinal connecting rod 4 is fixed between the rear supporting leg 1 and the front supporting leg 15. A seat plate 5 is movably connected between the rear supporting leg 1 and the front supporting leg 15, and an auxiliary mounting plate 6 is fixed between the rear supporting leg 1 and the front supporting leg 15. The seat plate 5 is located above the auxiliary mounting plate 6. A backrest 7 is fixed to the bottom of the top rod 2, and connecting columns 8 are fixed on both sides of the backrest 7, and the connecting columns 8 are fixedly connected to the rear supporting leg 1. The solid wood chair solves the problem that the existing solid wood chair has low strength, and the solid wood chair will affect the stability of the connection of the solid wood chair when subjected to pressure. Since the user will also move and squeeze laterally when riding the solid wood chair, the solid wood chair is prone to shaking and instability after being used for a period of time.

[0022] The backrest 7 adopts an arc-shaped design and is located at the center of the top rod 2. The arc-shaped design can fit the user's back better and avoid the back not fitting well enough to affect the riding comfort.

[0023] A fitting groove 9 is provided on the top of the seat plate 5, and a plurality of anti-slip strips 10 are fixed inside the fitting groove 9. The fitting groove 9 can fit the user's buttocks, and the anti-slip strips 10 can improve the anti-slip performance of the ride.

[0024] The bottoms of the front support legs 15 and the rear support legs 1 are both covered with a buffer sleeve 11 , which is made of rubber material. The buffer sleeve 11 can reduce impact and reduce noise generated by collision.

[0025] A plurality of ventilation holes 12 are provided on the surface of the backrest 7 , and cushions 13 are fixed on both sides of the surface of the backrest 7 . The ventilation holes 12 can realize the ventilation function, and the cushions 13 can cushion the back of the user.

[0026] A reinforcing rod 14 is fixed to the inner side of the front supporting leg 15 and the rear supporting leg 1. The other end of the reinforcing rod 14 is fixedly connected to the surface of the auxiliary mounting plate 6. The reinforcing rod 14 can improve the strength of the auxiliary mounting plate 6 and increase its compressive resistance.

[0027] Working principle: When using the solid wood chair, the user needs to sit on the seat plate 5, which can be supported by the auxiliary mounting plate 6, and the four sides of the seat plate 5 will be stuck on the surface of the front support leg 15 and the rear support leg 1. Since the front support leg 15 and the rear support leg 1 are designed as an integrated whole, there is no connection point between the seat plate 5, so it will not loosen during shaking and lateral movement. The horizontal fixing rod 3 and the longitudinal connecting rod 4 at the bottom can connect the two rear support legs 1 and enhance the compressive strength of the legs, while the reinforcing rod 14 can increase the strength of the auxiliary mounting plate 6 and increase the compressive resistance. When riding, the buffer cover 11 can reduce the impact and reduce the noise generated by the collision. The ventilation holes 12 of the backrest 7 can realize the ventilation function, and the cushion 13 can cushion the user's back.
