[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0028] Example 1
[0029] Reference Figure 1-4 , which is the first embodiment of the utility model, provides a folding auditorium chair device, the folding auditorium chair device comprises a support seat 1 and a cushion 2 arranged at the upper end of the support seat 1, a seat cushion 3 is arranged at the middle end of the support seat 1, an adjustment component 4 is arranged in the inner cavity of the support seat 1, and an unfolding component 5 is connected to the upper end of the adjustment component 4;
[0030] The adjustment assembly 4 includes a first driving wheel 41 arranged at the connection between the seat cushion 3 and the support seat 1, and the outer wall of the first driving wheel 41 is connected to the first transmission wheel 43 through the first transmission belt 42, and one end of the first transmission wheel 43 is connected to two symmetrical groups of first adjustment rods 44, and the upper ends of the two groups of first adjustment rods 44 are both provided with second adjustment rods 45, and the middle part of the lower end of the second adjustment rod 45 is connected to the first support rod 46, the lower end of the second adjustment rod 45 is connected to the third adjustment rod 47, and the lower end of the third adjustment rod 47 is connected to the fourth adjustment plate 48, and the upper end of the fourth adjustment plate 48 is provided with a second support rod 49, the first driving wheel 41 and the support seat 1 is rotatably connected to the inner wall of the support seat 1, the first driving wheel 41 is transmission-connected to the first transmission wheel 43 through the first transmission belt 42, the second adjusting rod 45 is rotatably connected to the first adjusting rod 44, the lower end of the second adjusting rod 45 is rotatably connected to the third adjusting rod 47, the end of the second adjusting rod 45 away from the first adjusting rod 44 is rotatably connected to the first supporting rod 46, one side of the lower end of the third adjusting rod 47 is rotatably connected to the fourth adjusting plate 48, and the upper end of the fourth adjusting plate 48 is rotatably connected to the second supporting rod 49, the lower end of the third adjusting rod 47 is rotatably connected to the inner wall of the bottom end of the supporting seat 1, and the upper ends of the first supporting rod 46 and the second supporting rod 49 are fixedly connected to the arm seat 51;
[0031] The unfolding assembly 5 includes an arm seat 51 disposed at the upper end of the first support rod 46 , and the arm seat 51 is movably inserted at the upper end of the support seat 1 .
[0032] When the conference personnel sit on the seat cushion 3, the seat cushion 3 rotates downward to drive the first driving wheel 41 to rotate, and the first driving wheel 41 drives the first driving wheel 43 to rotate through the first transmission belt 42, so that the first transmission wheel 43 drives the first adjusting rod 44 to rotate downward clockwise with the center of the first transmission wheel 43 as the axis. Since the second adjusting rod 45 is rotationally connected to the first adjusting rod 44, and the upper end of the third adjusting rod 47 is rotationally connected to the lower end of the second adjusting rod 45; the lower end of the third adjusting rod 47 is rotationally connected to the lower end of the support seat 1, so that under the adjustment of the third adjusting rod 47, the second adjusting rod 45 rotates counterclockwise with the connection between the second adjusting rod 45 and the first adjusting rod 44 as the axis, and at the same time drives the third adjusting rod 47 to be connected with the support seat 1 as the axis. Rotate counterclockwise, since one side of the third adjusting rod 47 is rotatably connected to the fourth adjusting plate 48, the fourth adjusting plate 48 rotates clockwise with its contact point with the third adjusting rod 47 as the axis, and the first support rod 46 and the second adjusting rod 45 are rotatably connected, and the fourth adjusting plate 48 and the second support rod 49 are rotatably connected, so that the first support rod 46 and the second support rod 49 drive the arm seat 51 to slide toward the outer wall of the support seat 1. When the seat cushion 3 is horizontal, the arm seat 51 is fully extended, so that the arm can be placed on the upper end of the arm seat 51. Similarly, after the meeting personnel leave the seat cushion 3, during the process of automatic recovery of the seat cushion 3, according to the above operation, the arm seat 51 is automatically recovered, thereby increasing the area of the aisle and facilitating people to move around.
[0033] Example 2
[0034] Reference Figure 1-4 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that: the unfolding assembly 5 also includes a tooth plate 52 arranged on the inner wall of the support seat 1, and the tooth plate 52 is located in the inner cavity of the arm seat 51;
[0035] The unfolding assembly 5 also includes a gear 53 arranged on one side of the toothed plate 52, and a second driving wheel 54 is arranged at the lower end of the gear 53, and the outer wall of the second driving wheel 54 is connected to the second transmission wheel 56 through a second transmission belt 55, and the two ends of the second transmission belt 55 are wound around the outer walls of the gear 53 and the second transmission wheel 56, and the lower end of the second driving wheel 54 is rotatably connected to the inner wall of the lower end surface of the arm seat 51, and a latching tooth that meshes with the gear 53 is arranged on one side of the toothed plate 52 close to the second transmission wheel 56;
[0036] The unfolding assembly 5 further includes a writing board 57 disposed at the lower end of the second transmission wheel 56, and the lower end of the writing board 57 is rotatably connected to the inner wall of the lower end surface of the arm seat 51;
[0037] The unfolding assembly 5 further includes a through slot 58 which is provided on one side of the arm seat 51 and matches with the writing board 57 .
[0038] When the arm seat 51 is pulled out, the gear 53 moves in the direction of the meshing teeth of the tooth plate 52 and the gear 53. When the meshing teeth and the gear 53 come into contact, the gear 53 rotates, driving the second driving wheel 54 to rotate. The second driving wheel 54 rotates through the second transmission belt 55 to drive the second transmission wheel 56 to rotate. The second transmission wheel 56 rotates to drive the writing board 57 to rotate. Therefore, when the arm seat 51 slides out of the support seat 1, the writing board 57 also rotates at the same time, and gradually unfolds toward the outside of the arm seat 51 through the through groove 58. When the arm seat 51 is completely pulled out, the writing board 57 is also completely unfolded to facilitate the conference staff to write and record. Similarly, when the staff leaves the cushion 3, the arm seat 51 is gradually retracted, and the writing board 57 is also automatically retracted. The above-mentioned device can be unfolded and retracted while the arm seat 51 is pulled out and retracted, which solves the problem that the conference staff need to retract the writing board 57 by themselves, thereby increasing the practicality of the device.
[0039] The remaining structures are the same as those of Example 1.
[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
