[0042] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0043] Embodiment:

[0044] As Figures 1 to 6 shown, a simple folding table includes: a tabletop 1, a tabletop support lifting rod 2 and an underframe 3. A folding mechanism 4 is arranged below the tabletop 1. The folding mechanism 4 is connected to the tabletop support lifting rod 2 below, and the tabletop support lifting rod 2 is arranged on the underframe 3. The tabletop 1 is folded through the folding mechanism 4 to realize the storage of the tabletop 1. By contracting the tabletop support lifting rod 2, the lifting of the tabletop 1 is realized to adjust the height of the tabletop.

[0045] As Figures 1 to 6 shown, the folding mechanism 4 includes a connecting plate 41 arranged below the tabletop 1, a sliding clamping plate member 5 arranged on the connecting plate 41, and a rotating shaft 42 passing through the tabletop support lifting rod 2. The rotating shaft 42 is located at the center of the sliding clamping plate member 5 and is fixedly connected. The rotating shaft 42 is connected to a handrail portion 6. The user holds the handrail portion 6 and rotates it, driving the rotating shaft 42 to rotate. The rotating shaft 42 rotates inside the tabletop support lifting rod 2, and the rotating shaft 42 drives the sliding clamping plate member 5 to rotate, thereby driving the tabletop 1 on the connecting plate 41 to fold for storage.

[0046] In this embodiment, the hand-held part 6 includes a connecting shaft 61 connected to the rotating shaft 42 and a pressing plate 62. The pressing plate 62 is arranged at one end of the connecting shaft 61 away from the rotating shaft 42. The user can press the pressing plate 62 with the hand, thereby driving the connecting shaft 61 to rotate. The connecting shaft 61 drives the rotating shaft 42 to rotate, improving the rotation convenience of the rotating shaft 42.

[0047] As Figures 1 to 6 shown, the sliding clamping plate member 5 includes a back plate 51, a left clamping plate 52 and a right clamping plate 53. The back plate 51, the left clamping plate 52 and the right clamping plate 53 are integrally formed. The left clamping plate 52 and the right clamping plate 53 extend from both sides of the back plate 51. The left clamping plate 52 and the right clamping plate 53 are located on both sides of the tabletop support lifting rod 2. The whole plate structure is processed and bent to form the back plate 51, the left clamping plate 52 and the right clamping plate 53, thereby shortening the process flow, reducing the process cost, and the integrally formed sliding clamping plate member 5 has strong firmness and high connection stability, improving the folding stability of the tabletop 1.

[0048] Among them, a stop elastic member 7 is arranged on one side of the left clamping plate 52 close to the tabletop support lifting rod 2. The stop elastic member 7 includes a disc-shaped main body 71 and several layers of stop elastic layers 72. The disc-shaped main body 71 is connected to the left clamping plate 52 by bolts, and several layers of stop elastic layers 72 are stacked on one side of the disc-shaped main body 71 close to the tabletop support lifting rod 2. In this embodiment, the active elastic member can be but is not limited to rubber. Through the elasticity of the stop elastic member 7, the stop elastic member 7 abuts against the tabletop support lifting rod 2, and the tabletop 1 is fixed through the frictional force of the abutment, improving the stability of the tabletop 1 during use.

[0049] Among them, several layers of stop elastic layers 72 are disc-shaped, and the diameters of several layers of stop elastic layers 72 gradually become smaller in the direction close to the tabletop support lifting rod 2, so that the contact area contacting the tabletop support lifting rod 2 becomes more as the pressure increases. When the tabletop 1 is unstable or shaking, the lateral force of the tabletop 1 increases, and the contact area between the stop elastic member 7 and the tabletop support lifting rod 2 increases, thereby increasing the static friction force between the stop elastic member 7 and the tabletop support lifting rod 2 and stabilizing the tabletop 1.

[0050] As Figures 1 to 6 shown, the right clamping plate 53 is provided with an arc-shaped groove 531, and the tabletop support lifting rod 2 protrudes with a limit screw 21 extending into the arc-shaped groove 531 to control the tabletop flipping angle.

[0051] Among them, one end of the left clamping plate 52 connected to the connecting plate 41 is provided with a left thickened chamfer 521; one end of the right clamping plate 53 connected to the connecting plate 41 is provided with a right thickened chamfer 532. Through the left thickened chamfer 521 and the right thickened chamfer 532, the connection strength between the left clamping plate 52, the right clamping plate 53 and the connecting plate 41 is improved.

[0052] As Figures 1 to 6 shown, a stop mechanism is provided within the tabletop support lifting rod 2 where the rotating shaft 42 is located to fix the tabletop before and after folding. The stop mechanism can adopt a structure of engaging teeth. Tooth grooves are formed on the rotating shaft 42, and the fixing member is inserted into the tooth grooves to stop the rotating shaft 42.

[0053] Among them, two detachable end caps 22 are arranged side by side at the upper end of the tabletop support lifting rod 2. The detachable end caps 22 are in interference connection with the tabletop support lifting rod 2. Through the detachable end caps 22, the top is sealed, which is convenient for the staff to repair and shortens the process flow and cost.

[0054] As Figures 1 to 6 shown, baffles 43 are turned up on one side of the connecting plate 41 where the back plate 51, the left clamping plate 52, and the right clamping plate 53 are located. The baffles 43 are located at the edge of the connecting plate 41 to protect several structures inside the connecting plate 41.

[0055] In this embodiment, rollers 31 are provided under the chassis 3 to facilitate the user to move the folding table.

[0056] In summary: Through the integral molding of the sliding clamping plate member 5, and by simply passing the rotating shaft 42 through the tabletop support lifting rod 2, the entire tabletop 1 is folded and stored around the rotating shaft 42, which not only has a simple overall structure, but also shortens the manufacturing process, shortens the manufacturing time, and reduces the cost. Through the limit screw 21 in the arc-shaped groove 531, the folding angle of the tabletop 1 is restricted, improving the rotation safety. Through the left thickened chamfered portion 521 and the right thickened chamfered portion 532, the connection strength between the left clamping plate 52, the right clamping plate 53, and the connecting plate 41 is improved. Through the detachable end cap 22, the top is sealed, which is convenient for the staff to repair and shortens the process flow and cost.
