[0028] The utility model provides an office chair assembly device, including an upper support leg 101, a clamping mechanism, a lifting mechanism, a control console 102 and a base 103, the clamping mechanism includes a clamping claw 104, an adjustment frame 105, an adjustment rod 106, a positioning plate 107, a latch 108, a friction pad 109, a U-shaped frame 110 and a telescopic component 111, the telescopic component 111 includes a cylinder 112 and a telescopic rod 113, the lifting mechanism includes a second oblique rod 114, a first oblique rod 115, a slider 116, a connecting piece 117 and a driving component 118, the connecting piece 117 includes a connecting plate 119 and a connecting bolt 120, and the driving component 118 includes a sliding column 121 and an electric push rod 122. The above-mentioned scheme solves the problem that although the assembly of the walking wheels can be realized in the prior art, when fixing the turntable, it is necessary to manually step on the L-shaped plate to insert the square plate into the square groove of the rotating shaft, and the position of the square groove needs to be adjusted to correspond to the square plate, so the rotating shaft cannot be fixed quickly. It can be understood that the above-mentioned scheme can also solve the problem that it is inconvenient for the operator to observe and place the card rod slot in the chair frame in the card rod. The height adjustment of the console can be achieved through the lifting mechanism, which is convenient for observation and the card rod slot of the chair frame is placed in the card rod.

[0029] According to this specific embodiment, the base 103 is fixedly connected to the upper support leg 101 and is located on the inner wall of the upper support leg 101. The console 102 is slidably connected to the upper support leg 101 and is located above the base 103. A cavity is provided in the console 102 for placing the clamping mechanism, and sliding grooves are provided below the console 102 and above the base 103, and are symmetrical to each other. The lifting mechanism is located between the console 102 and the base 103. The clamping mechanism is used to quickly clamp and fix the rotating shaft. The lifting mechanism is used to adjust the height of the console 102 for easy observation, and the card rod slot of the chair frame is placed in the card rod.

[0030] The positioning plate 107 is fixedly connected to the console 102 and is located on the inner wall of the console 102. The bolt 108 is fixedly connected to the positioning plate 107 and penetrates the positioning plate 107. The adjustment frame 105 is rotatably connected to the bolt 108 and is located on the outer wall of the bolt 108. An adjustment hole 123 is provided on the adjustment frame 105. The tail ends of the two adjustment frames 105 have different mechanisms. The tail end of one of the adjustment frames 105 is located between the tail ends of the other adjustment frames 105. The two adjustment frames 105 are slidably connected. The adjustment rod 106 is slidably connected to the adjustment frame 105 and is located on the adjustment frame 105. The U-shaped frame 110 is fixedly connected to the adjusting rod 106 and is located at both ends of the adjusting rod 106. The telescopic component 111 is located on one side of the U-shaped frame 110. The clamping claw 104 is fixedly connected to the adjusting frame 105 and is located on one side of the adjusting frame 105. By starting the telescopic component 111, the telescopic component 111 pulls the U-shaped frame 110 to move away from the adjusting frame 105. Since the U-shaped frame 110 is fixedly connected to the adjusting rod 106, the U-shaped frame 110 drives the adjusting rod 106 to move, thereby driving the clamping claw 104 on the adjusting frame 105 to clamp and fix the rotating shaft.

[0031] At the same time, the cylinder 112 is fixedly connected to the console 102 and is located on the inner wall of the console 102. The telescopic rod 113 is fixedly connected to the cylinder 112 and is located on one side of the cylinder 112. The other side of the telescopic rod 113 is fixedly connected to the U-shaped frame 110. The cylinder 112 provides power to realize the telescopic movement of the telescopic rod 113, thereby achieving clamping and fixing of the rotating shaft.

[0032] The friction pad 109 is fixedly connected to the clamping claw 104 and is located at a side of the clamping claw 104 away from the adjustment frame 105 . The friction pad 109 is used to prevent the shaft from being worn during the clamping process.

[0033] Secondly, there are multiple connecting members 117, which are respectively located between the console 102 and the base 103. There are multiple sliders 116, which are slidably connected to the base 103 and the console 102, and are respectively located in the base 103 and the console 102. One end of the first inclined rod 115 is rotatably connected to the console 102 through the connecting member 117 and is located below the console 102. The other end of the first inclined rod 115 is rotatably connected to the slider 116 through the connecting member 117 and is located above the base 103. One end of the second inclined rod 114 is rotatably connected to the base 103 through the connecting member 117 and is located above the base 103. The other end of the second inclined rod 114 is rotatably connected to the slider 116 through the connecting member 117 The control console 102 is rotatably connected and is located below the control console 102. The driving assembly 118 is located above the base 103. The plurality of connecting bolts 120 are rotatably connected to the first oblique rod 115 and the second oblique rod 114, respectively, and penetrate the first oblique rod 115 and the second oblique rod 114, respectively. The connecting plate 119 is detachably connected to the connecting bolt 120 and is located on the outer wall of the connecting bolt 120. The second oblique rod 114 and the first oblique rod 115 are used to support the control console 102 for up and down height adjustment. The driving assembly 118 provides power for the lifting of the control console 102. The connecting piece 117 is used to support the second oblique rod 114 and the first oblique rod 115. The slider 116 is used to move in the sliding groove in the base 103, thereby adjusting the position of the connecting piece 117 on the slider 116.

[0034] In addition, the electric push rod 122 is fixedly connected to the base 103 through a cylinder and is located above the base 103. The sliding column 121 is fixedly connected to the electric push rod 122 and is located on one side of the electric push rod 122. The sliding column 121 is also fixedly connected to the connecting plate 119 and is located on one side of the connecting plate 119. The electric push rod 122 is used to move the sliding column 121. The sliding column 121 is used to change the position and angle of the first diagonal rod 115 relative to the base 103 by driving the slider 116 to slide.

[0035] When using an office chair assembly device of the present embodiment, after placing the walking wheel on the turntable, the cylinder 112 is started to realize the extension and retraction of the telescopic rod 113. Since the telescopic rod 113 is fixedly connected to the U-shaped frame 110, the U-shaped frame 110 is driven to move in the direction of the cylinder 112. Then, the adjusting rod 106 is fixedly connected to the U-shaped frame 110, thereby driving the adjusting rod 106 to pull the adjusting frame 105, so that the adjusting frame 105 rotates with the clamping bolt 108 on the positioning plate 107 as a fixed point. The clamping claw 104 is fixedly connected to the adjusting frame 105, so that the clamping claw 104 can quickly clamp and fix the rotating shaft, and then the sliding column 121 is moved by starting the electric push rod 122. Since the sliding column 121 is fixedly connected to the connecting plate 119 on the slider 116, the slider 116 slides in the sliding groove in the base 103. At the same time, since the other end of the first inclined rod 115 and the other end of the second inclined rod 114 are rotatably connected to the slider 116 through the connecting piece 117, the first inclined rod 115 and the second inclined rod 114 are driven to rotate on the connecting bolt 120. The position and angle of the first inclined rod 115 relative to the base 103 are changed by the driving assembly 118, and the position and angle of the second inclined rod 114 relative to the console 102 are changed, thereby realizing the height adjustment of the console 102, which is convenient for the operator to observe and place the card rod slot of the chair frame in the card rod.
