Detailed Description of the Embodiment

[0019] The following further describes the present utility model in detail with reference to the drawings.

[0020] This embodiment discloses a chair convenient for adjusting the armrest, as Figures 1 to 7As shown, the utility model has the effect of facilitating the adjustment of the armrest position to fully relax the arm, including two support platforms 1; the support platforms 1 are made of iron; a seat surface is arranged between the support platforms 1; the seat surface is composed of eleven seat boards 2 and eleven backrests 3; both the seat boards 2 and the backrests 3 are made of wood; a backrest 3 is arranged on one side of the seat board 2; the seat board 2 and the backrest 3 are integrally formed; the seat board 2 and the backrest 3 can be flipped; a limiting rod 4 and two stabilizing rods 5 are arranged on the support platform 1; the stabilizing rod 5 is arranged at the bottom of the seat board 2 and cooperates with the seat board 2; the limiting rod 4 is arranged on one side of the seat board 2; two limiting strips 6 are arranged on the limiting rod 4; a screw rod 7 is also arranged on the support platform 1; two inner nuts 8 and two outer nuts 9 are arranged on the screw rod 7.

[0021] By adopting the above technical solutions: The support platforms 1 are firmly connected through the screw rod 7, inner nuts 8, outer nuts 9, limiting rod 4, and limiting strips 6; the seat surface is composed of the seat board 2 and the backrest 3. The seat board 2 can be arranged on the stabilizing rod 5 to make the seat board 2 firmly set. The limiting rod 4 prevents the seat board 2 from tilting on the stabilizing rod 5, so that the seat board 2 is further firmly set on the stabilizing rod 5; the backrest 3 can become an armrest after being flipped; after the seat board 2 and the backrest 3 are flipped, they can be arranged between the limiting rod 4 and the stabilizing rod 5, as Figure 1 shown, so that the arm can be placed on different armrests, which facilitates the adjustment of the armrest position to fully relax the arm.

[0022] A total of four first holes 10 and two second holes 11 are opened on the support platform 1. Two first holes 10 and one second hole 11 are opened on each support platform 1; the stabilizing rod 5 penetrates through the first hole 10; the limiting rod 4 penetrates through the second hole 11; a total of two through holes 12 are opened on the support platform 1. One through hole 12 is opened on each support platform 1; the screw rod 7 is arranged in the through hole 12; the support platform 1 is arranged between the inner nut 8 and the outer nut 9.

[0023] By adopting the above technical solutions: The two stabilizing rods 5 respectively pass through the first holes 10 to make the stabilizing rods 5 firmly set in the support platform 1 and the stabilizing rods 5 are vertically arranged between the support platforms 1; the limiting rod 4 passes through the second hole 11 to make the limiting rod 4 firmly set in the support platform 1; when connecting the support platform 1 and the screw rod 7, the inner nut 8 can be first screwed to the middle of the screw rod 7, and then the two ends of the screw rod 7 are respectively penetrated through the through holes 12 on the support platform 1 to connect the support platform and the screw rod; then adjust the positions of the two support platforms 1 so that the seat board 2 and the backrest 3 can be arranged between the two support platforms 1. Finally, screw the inner nut 8 to contact the support platform 1 and at the same time screw the outer nut 9 to contact the support platform 1, and the support platform 1 is firmly set through the inner nut 8 and the outer nut 9.

[0024] Two mating grooves 13 are formed at the bottom of the seat board 2; the bottom of the seat board 2 is inclined; the seat board 2 is arranged on the stabilizing rod 5 through the mating grooves 13; the limiting rod 4 is in contact connection with the seat board 2; after the seat board 2 and the backrest 3 are flipped, the seat board 2 is arranged between the stabilizing rod 5 and the limiting rod 4 on the side close to the limiting rod 4; the backrest 3 becomes an armrest after being flipped; twenty-two limiting holes 14 are formed in the limiting rod 4; the limiting holes 14 are located at both ends of the limiting rod 4 and eleven limiting holes 14 are formed at each end; two limiting strips 6 are arranged in the limiting holes 14; the limiting strips 6 are respectively arranged in different limiting holes 14; the limiting strips 6 are made of iron.

[0025] By adopting the above technical solutions: the two mating grooves 13 formed at the bottom of the seat board 2 enable the seat board 2 to be stably arranged on the stabilizing rod 5; the inclination of the bottom of the seat board 2 enables the seat board 2 to be arranged between the stabilizing rod 5 and the limiting rod 4 on the side close to the limiting rod 4; the contact connection between the limiting rod 4 and the seat board 2 facilitates the separation of the seat board 2 from the limiting rod 4 when the seat board 2 is flipped; the backrest 3 becomes an armrest after being flipped, which is convenient for placing the arm on the armrest so that the arm can be fully relaxed.

[0026] The limiting holes 14 and the limiting strips 6 make the support table 1 more stable. That is, the bottom of the support table 1 is made stable through the screw 7, the inner nut 8, and the outer nut 9, and the upper part of the support table 1 is made stable through the limiting holes 14 and the limiting strips 6. Through the above settings, the support table 1 is made stable; when it is necessary to increase the area of the seat surface, the limiting strip 6 can be taken out of the limiting hole 14, the inner nut 8 and the outer nut 9 are respectively rotated to the two side edges of the screw 7 and then the support table 1 is moved towards the edge of the screw, so that the distance between the support tables 1 becomes wider. Then the limiting strip 6 is arranged in the limiting hole 14 near the edge of the limiting rod 4. After the adjustment is completed, the inner nut 8 is rotated until it contacts the support table 1 and at the same time the outer nut 9 is rotated until it contacts the support table 1, so that the number of the seat board 2 and the backrest 3 arranged on the stabilizing rod 5 can be increased, thereby increasing the seat surface area. When it is necessary to reduce the area of the seat surface, the limiting strip 6 can be taken out of the limiting hole 14, the inner nut 8 and the outer nut 9 are respectively rotated to the middle of the screw 7 and then the support table 1 is moved towards the middle of the screw, so that the distance between the support tables 1 becomes narrower. Then the limiting strip 6 is arranged in the limiting hole 14 near the middle of the limiting rod 4. After the adjustment is completed, the inner nut 8 is rotated until it contacts the support table 1 and at the same time the outer nut 9 is rotated until it contacts the support table 1, so that the number of the seat board 2 and the backrest 3 arranged on the stabilizing rod 5 can be reduced, thereby reducing the seat surface area.

[0027] In summary, the utility model has the following beneficial effects: a seat surface is arranged between the support platforms 1; the seat surface is composed of a plurality of seat boards 2 and a plurality of backrests 3, and the seat boards 2 are connected to the backrests 3; the support platforms 1 are connected and stabilized through screws 7, inner nuts 8, outer nuts 9, stabilizing rods 5, and limiting strips 6; the seat boards 2 can be detached from the stabilizing rods 5, so that after the seat boards 2 and the backrests 3 are flipped, the seat boards 2 are arranged between the stabilizing rods 5 and the limiting rods 4 on the side close to the limiting rod 4, making the backrests 3 become armrests for placing the arms. During adjustment, different seat boards 2 and backrests 3 can be flipped according to the actual situation of the user, so that the user's hands can be comfortably placed on the armrests, thus fully relaxing the arms.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present utility model shall be included within the protection scope of the present utility model.
