[0025] Referring to the drawings Figures 1-4 As shown in the drawings, the utility model embodiment a bleacher chair of adjustable inclination angle, including seat 1, one side of seat 1 is equipped with the hole, the hole is rotatably installed with rotating shaft 2, one end of rotating shaft 2 is fixedly connected with connecting block 102, the upper surface of connecting block 102 is fixedly installed with backrest 101, and the other end of rotating shaft 2 penetrates the hole and is located on one side of seat 1, and one side of seat 1 is provided with inclination adjusting assembly 3.

[0026] Rotating shaft 2 penetrates the fixed installation of adjusting gear 201 of one side extension section of seat 1, and the inclination adjusting assembly 3 and adjusting gear 201 can be matched to realize the inclination angle adjustment of backrest 101.

[0027] The backrest 101 can be conveniently and simply adjusted to a comfortable angle by the inclination adjustment assembly 3, and the traditional spring limit is reduced during adjustment, the fragile parts are reduced, the operation is facilitated, the simplicity is improved, and the inclination angle can meet the needs of different people by driving the backrest 101 to adjust through the rotating shaft 2. The overall structure does not need to be replaced regularly, and the maintenance cost is reduced.

[0028] The rotating shaft 2 adopting the technical scheme is adjusted and fixed by the adjustment gear 201, labor is saved, the difficulty of angle adjustment is reduced, and positioning is facilitated.

[0029] Referring to FIG. 1, Figures 3 to 4 As shown in the drawings, the inclination adjustment assembly 3 comprises a fixed block 301 fixedly installed on one side of the seat 1, a first rolling shaft 302 rotatably installed at one end of the upper surface of the fixed block 301, and an adjustment arc block 303 rotatably connected at one end of the first rolling shaft 302. A positioning block 304 is fixedly connected to one side of the inner wall of the adjustment arc block 303, and the adjustment arc block 303 can be fixed by being clamped into the tooth groove of the adjustment gear 201 through the positioning block 304. A second rolling shaft 306 is rotatably installed on one side of the fixed block 301, a rotating ring 309 is rotatably installed at one end of the second rolling shaft 306, and a linkage block 307 is fixedly connected at the other end of the rotating ring 309. An adjustment block 308 is fixedly installed at one end of the upper surface of the linkage block 307, and the other end of the linkage block 307 is fixedly connected to one side of the adjustment arc block 303. A limiting block 305 is arranged at the upper end of the second rolling shaft 306 on one side of the fixed block 301.

[0030] In order to improve the smoothness of the stand chair during adjustment, the design of the first rolling shaft 302 and the second rolling shaft 306 enables the adjustment arc block 303 to rotate more smoothly, which can reduce the occurrence of jamming. Then, the adjustment arc block 303 is clamped and fixed with the tooth groove of the adjustment gear 201 through the positioning block 304, which can accurately position the inclination angle of the backrest 101 and meet the individual needs of different users for the angle.

[0031] In order to improve the stability of the user during angle adjustment, the limiting block 305 installed on one side of the fixed block 301 can make the backrest 101 rotate in the opposite direction, ensure the stability of the entire inclination adjustment assembly 3 during adjustment and use, and further ensure the stability of the backrest after being fixed, so that the user can use more comfortably. The user only needs to operate the adjustment block 308 to drive the adjustment arc block 303 through the linkage block 307, the rotating ring 309 and other components to realize the adjustment of the angle of the backrest 101, which is simple and convenient to operate without complex operation process.

[0032] When the user adjusts the reclining angle, the adjusting block 308 is pushed, the linkage block 307 fixedly connected with the adjusting block 308 starts to move, since the other end of the linkage block 307 is connected with the rotating ring 309, the rotating ring 309 is rotatably installed on the second rolling shaft 306, the linkage block 307 drives the rotating ring 309 to rotate around the second rolling shaft 306, the other end of the linkage block 307 is connected with the adjusting arc block 303, the adjusting arc block 303 rotates around the first rolling shaft 302 while the rotating ring 309 rotates, the positioning block 304 on the inner wall of the adjusting arc block 303 is separated from the tooth groove of the adjusting gear 201 along with the rotation of the adjusting arc block 303, at this time, the backrest 101 is no longer fixed, the user can rotate the backrest 101 according to the requirement, the backrest 101 drives the rotating shaft 2 and the adjusting gear 201 to rotate together, when the reclining angle is adjusted to the appropriate angle, the adjusting block 308 is pushed in the reverse direction, the above-mentioned components operate in the reverse direction, the adjusting arc block 303 rotates back, the positioning block 304 is reinserted into the tooth groove of the adjusting gear 201, the backrest 101 is fixed at the new reclining angle, and the overall operation is simple and convenient.

[0033] In summary, the embodiment of the stand chair with adjustable reclining angle can complete the reclining angle adjustment of the stand chair without operation steps, the operation process is simple and convenient, the user does not need to spend much thought to study the complex operation process, the maintenance and management of the stand chair are more relaxed, the failure caused by improper operation can be effectively reduced, the maintenance cost is reduced, and the overall operation efficiency is improved.

[0034] The basic principle of the application is shown and described above, the above is only the preferred embodiment of the application, and does not limit the application, the above embodiment and the description in the specification only illustrate the principle of the application, any modification, equivalent replacement and improvement within the scope of the application should be included in the protection scope of the application.
