DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figures 1 to 5 , the utility model provides embodiments:

[0029] It includes a base 1, four first mounting frames 4 and four second mounting frames 5. The two side surfaces of the base 1 are integrally formed with support plates 2. Both sides of the surface of the support plate 2 are provided with slide grooves 3, one side of which passes through the surface of the support plate 2 and is installed with a limiting mechanism 9. The limiting mechanism 9 includes a fixed frame 91, a connecting frame 92, a connecting seat 93, a movable block 95 and a blocking rod 97. The two sides of the fixed frame 91 are symmetrically bolted with connecting frames 92. One side surface of the connecting frame 92 is welded to the connecting seat 93. Shrapnel 94 is welded on the two connecting seats 93. The fixed frame 91 and the two connecting frames 92 are matched and plugged into the slide groove 3. The two spring clips 94 pass through the slide groove 3 and are clamped on the surface of the support plate 2. The limit mechanism 9 is set to achieve a certain locking effect. When operation is required, the limit mechanism 9 is removed. At this time, there is no obstruction at the slide slot 3. Only the first mounting frame 4 and the second mounting frame 5 need to be pressed down to complete the folding of the dining table as a whole, thereby realizing the adjustment of the dining table. When locking is required, it is necessary to manually press the two spring pieces 94 so that the spring pieces 94 temporarily shrink to pass through the slide slot 3, and then turn the fixed frame 91 ninety degrees, loosen the spring pieces 94 so that it can be fixed in the slide slot 3 by the reaction force, and then the dining table will be pressed down again. The fixed frame 91 is used as a support and cannot be pressed down, thereby completing the locking action. A stop rod 97 is inserted on one side of the movable block 95, and the two ends of the movable block 95 are mounted between the inner surfaces of the fixed frame 91 through a torsion spring 96. The stop rod 97 part plays the role of auxiliary protection, and it is also convenient to directly hold the stop rod 97 position for operation.

[0030] The four first mounting frames 4 and the four second mounting frames 5 are movably connected through a damping shaft 6 , and a clamping mechanism 10 is installed in cooperation with the first mounting frames 4 and the second mounting frames 5 .

[0031] The clamping mechanism 10 includes a support frame 101, a fixed plate 102, a connecting shaft 103, a guide wheel 104 and a transmission belt 105. The surface of the support frame 101 is welded to the fixed plate 102. The surfaces of the fixed plate 102 are rotatably mounted with the connecting shaft 103 in turn through bearing cooperation. The surface of the connecting shaft 103 is key-connected with the guide wheel 104, and the table top 11 is slidably inserted between the guide wheels 104. The two side surfaces of the table board 11 are in contact with the surfaces of the guide wheels 104 on both sides respectively; a clamping mechanism 10 is provided to fix the table board 11. During use, the two sides of the table board 11 are aligned with the surfaces of the guide wheels 104 on both sides respectively, so that the table board 11 can be in the exact center position. At this time, the table board 11 is pushed manually. Since the guide wheels 104 on both sides can provide a certain extrusion force, there will be a certain resistance during the pushing process of the table board 11. This can also ensure that after the installation of the table board 11 is completed, the position of the table board 11 will not be easily offset due to external collisions. The installation action of the table board 11 is simplified through the cooperation of this structure, and it is easy to disassemble and assemble at any time. The two adjacent guide wheels 104 are connected by the transmission belt 105. The transmission belt 105 structure is provided to strengthen the correlation between the guide wheels 104, which can more effectively cooperate with the table board 11 for disassembly and assembly operations. A baffle 106 is provided on the top of the support frame 101, and the baffle 106 is an integrated molding structure on the surface of the support frame 101. The baffle 106 structure plays an auxiliary shielding role and can fully protect the installation structure of the guide wheel 104 to avoid easy damage.

[0032] A support mechanism 7 is provided on one side surface of the base 1. The support mechanism 7 includes a mounting seat 71, a support rod 72, a pressure spring 73 and a pressure rod 74. The surface of the mounting seat 71 is bolted to the surface of the base 1. The surface of the mounting seat 71 is plugged with a support rod 72. The support rod 72 is a hollow cylindrical structure. A pressure rod 74 is movably plugged at one end of the support rod 72, and a pressure spring 73 is provided between the pressure rod 74 and the inner wall of the support rod 72. A raised edge 75 is provided at one end of the pressure rod 74, and a cushion block 76 is provided at the other end of the pressure rod 74. The raised edge 75 is an integrated molding structure on the surface of the pressure rod 74, and the cushion block 76 is made of rubber material. When the table top 11 is pressed down, the cushion block 76 can be used to partially complete the cushioning, and it can cooperate with the pressure rod 74 and the pressure spring 73 at the other end to complete the buffering and support work to ensure overall safety.

[0033] The outer sleeve of the support rod 72 is connected with a reinforcing mechanism 8, which includes a fixed sleeve 81, a reinforcing rib 83, a connecting rod 84 and a limiting ring 85. The two ends of the fixed sleeve 81 are respectively and evenly welded to the connecting rod 84, and the other end of the connecting rod 84 is symmetrically welded with a limiting ring 85, one of which is welded and fixed to the surface of the mounting seat 71.

One side surface of the fixed sleeve 81 is welded to the reinforcing rib 83, and the reinforcing rib 83 is an integrated structure made of steel structural material. The reinforcing rib 83 structure further increases the structural strength of the fixed sleeve 81 to avoid breakage.
