[0033] The pneumatic push rod 201 is installed at the top rear end of the rectangular frame 101 and the top rear end of the vertical bracket 103, and the push plate 202 is fixed to the output end of the pneumatic push rod 201.

[0034] Horizontal through holes 203 are symmetrically opened on both sides of push plate 202 and completely penetrate the front and rear ends of push plate 202. Slide rod 205 passes through horizontal through holes 203 and is fixed to push plate 202 through adjustment unit.

[0035] The pressure plate 206 is fixed to the front end of the two slide rods 205. The pneumatic push rod 201 drives the push plate 202 and the pressure plate 206 to move as a whole, so as to realize the pressing operation of the pressure plate 206 on the dining chair 3.

[0036] The adjustment unit includes a vertical through hole 204, a locking hole 207, a T-shaped post 208, a connecting plate 209, a sleeve hole 210, a locking rod 211, and a spring 212;

[0037] Vertical through holes 204 are symmetrically opened on both sides of the top of the push plate 202 and completely penetrate the horizontal through holes 203; lock holes 207 are opened on the top of the slide bar 205 and completely penetrate the bottom of the slide bar 205.

[0038] T-shaped columns 208 are symmetrically fixed to the top of push plate 202, and sleeve holes 210 are symmetrically opened on the top of connecting plate 209 and completely penetrate the bottom of connecting plate 209. Connecting plate 209 is slidably sleeved on the outside of T-shaped columns 208 through sleeve holes 210.

[0039] The locking rod 211 is symmetrically fixed on both sides of the bottom of the connecting plate 209, and the locking rod 211 passes through the vertical through hole 204 and a locking hole 207 to realize the limiting and fixing of the slide rod 205 and the push plate 202;

[0040] Spring 212 is sleeved on the outside of T-shaped post 208 and distributed on the top of connecting plate 209 and between the top protrusions of T-shaped post 208. Spring 212 continuously provides compressive force to connecting plate 209.

[0041] Multiple lock holes 207 are provided along the long side of the slide bar 205. The multiple lock holes 207 are evenly arranged according to the standard scale or positioned according to the common model size of the dining chair 3.

[0042] In this embodiment, the dining chair assembly table is used as follows:

[0043] The pre-assembled dining chair 3 is placed inside the rectangular frame 101. The U-shaped support frame 102 provides support for the placement of the dining chair 3. The backrest of the dining chair 3 faces backward and the front end of the seat cushion is attached to the rear end face of the vertical support 103.

[0044] Then, the pneumatic push rod 201 on the rectangular frame 101 is activated. The pneumatic push rod 201 drives the push plate 202, slide rod 205 and pressure plate 206 to move as a whole. Finally, the pressure plate 206 presses against the legs of the dining chair 3 to achieve horizontal pressing of the dining chair 3.

[0045] Then, the pneumatic push rod 201 on the vertical support 103 is activated, causing the corresponding pressure plate 206 to move down and press the upper surface of the seat cushion of the dining chair 3. After that, the staff simultaneously and manually tapped and reinforced each joint of the dining chair 3. After that, the press was maintained for a certain period of time. In this way, it was ensured that the overall frame of the dining chair 3 was square, without twisting, and the joints were tight and without gaps.

[0046] When the dimensions of the dining chair 3 to be processed change, the positions of the vertical pressure plate 206 and the horizontal pressure plate 206 need to be adjusted according to the height and depth of the chair cushion. By manually pulling the connecting plate 209 upward, the connecting plate 209 compresses the spring 212 and further contracts, while driving the locking rod 211 upward and completely separating it from the lock hole 207, thereby releasing the lock on the slide rod 205. At this time, the other pressure plate 206 is moved horizontally. When the pressure plate 206 is adjusted to the appropriate position (the adjustment distance of the pressure plate 206 can be judged by the position change of the lock hole 207), the pulling force on the connecting plate 209 is released. The connecting plate 209 and the locking rod 211 are reset under the elastic force of the spring 212. The locking rod 211 is inserted into the corresponding position of the lock hole 207, thus fixing the position of the pressure plate 206.

[0047] By adjusting the position of the pressure plate 206, the pressure on the dining chair 3 can be kept within a suitable range while the stroke of the pneumatic push rod 201 remains unchanged, thus avoiding excessive or insufficient pressure that could cause the frame of the dining chair 3 to twist or become unstable during assembly.

[0048] Please refer to this carefully. Figures 1-3 Sliding bearing seats 213 are installed on the top two sides of the rectangular frame 101 and the rear two sides of the vertical support 103. The sliding rod 205 passes through the sliding bearing seat 213 and is slidably connected to the sliding bearing seat 213.

[0049] In this embodiment, it should be noted that when the pneumatic push rod 201 is fully retracted and the pressure plate 206 is in the state closest to the push plate 202, the position of the lock hole 207 still does not contact the sliding bearing seat 213, that is, the surface of the slide rod 205 in contact with the sliding bearing seat 213 is a smooth surface.

[0050] The sliding bearing seat 213 can guide and support the movement of the slide rod 205, preventing the slide rod 205 from shaking, thereby improving the movement stability of the pressure plate 206.

[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
