[0002] The folding long table has good storage capacity and is therefore favored by more and more young people.

[0003] At present, a Chinese patent with the authorization announcement number CN216364096U discloses a folding long table imitating solid wood, including a hollow table top, two connecting strips are arranged side by side on the bottom surface of the table top, two reinforcing plates are symmetrically arranged in the middle of the two connecting strips, and the two connecting strips are hinged with a footrest at the opposite ends, and a support column is hinged at the side wall of the reinforcing plate. The end of the support column away from the reinforcing plate is hinged with a receiving strip, and the receiving strip is hinged to the footrest. A locking ring is provided on the sliding sleeve at the connection between the receiving strip and the support column. The locking ring can be used to limit the hinged rotation of the footrest, so that the footrest remains fixed under impact, which has the advantage of good stability. The top surface of the table top is provided with wood grain, which can improve the anti-slip performance of the top surface of the table top on the one hand, and improve the decorativeness of the folding long table on the other hand.

[0004] This imitation solid wood folding long table has good stability. When in use, people put the plates with dishes on the table top. When picking up the dishes with chopsticks, it is inevitable that a small amount of soup will drip onto the table top, which can easily breed bacteria on the surface of the table top. Utility Model Content

[0005] In view of this, the utility model aims to provide an antibacterial and antifouling plastic folding long table, which achieves the purpose of antibacterial and antifouling by coating a bamboo fiber resin layer on a placement board.

[0006] In order to solve the above technical problems, the technical solution of the utility model is: an antibacterial and anti-fouling plastic folding long table, comprising supporting legs, a supporting frame, a table top, a connecting rod, a rotating rod, and a cross rod. The table top is fixed to the upper surface of the supporting frame, and the supporting legs are fixed to the outer wall of the cross rod. Both ends of the cross rod are rotatably connected to one end of the supporting frame, one end of the connecting rod is hinged to the end of the supporting frame away from the cross rod, and the other end of the connecting rod is hinged to the rotating rod. The end of the rotating rod away from the connecting rod is hinged to the middle part of the supporting leg, a limiting ring is arranged between the connecting rod and the rotating rod, and the two supporting frames are hinged by a pin shaft. The table top comprises a supporting plate and a placing plate. The supporting plate is fixedly connected to the supporting frame, and the placing plate is connected to the upper surface of the supporting plate. A plurality of the placing plates are arranged along the length direction of the supporting plate. The placing plates are connected to the supporting plates by a positioning mechanism, and the upper surface of the placing plates is coated with a bamboo fiber resin layer.

[0007] To implement the above technical solution, a bamboo fiber resin layer is coated on the placement board. The bamboo fiber has a natural antibacterial effect. After the resin is cured on the surface of the placement board, the surface is relatively smooth and easy to wipe with a rag, thereby achieving an anti-fouling effect. The placement board is placed on the support board from top to bottom, and the placement board is fixedly connected to the support board through a positioning mechanism. The limiting ring is set on the connecting rod, and the supporting legs are flipped along the cross rod. The rotating rod and the connecting rod are rotated to make the supporting legs flip toward the lower surface of the supporting board to achieve a folding effect. The supporting legs are flipped in the direction away from the support board, and the limiting ring is set on the connecting rod and the rotating rod to prevent the connecting rod and the rotating rod from rotating, thereby achieving the positioning of the supporting legs, and the operation is simple.

[0008] As a preferred solution of the utility model, the positioning mechanism includes a positioning recessed hole, a positioning protrusion, and a spring sheet. The positioning recessed hole is opened on the upper surface of the support plate, the positioning protrusion is fixed to the lower surface of the placement plate, the spring sheet is U-shaped and its two ends are fixedly connected to the side walls of the positioning protrusion. A positioning arc surface with a U-shaped cross-section is opened on the inner wall of the positioning recessed hole, and the middle part of the spring sheet is embedded in the positioning arc surface.

[0009] To implement the above technical solution, the placement plate is moved from top to bottom toward the support plate so that the positioning protrusion is inserted into the positioning recessed hole. The spring sheet contacts the inner wall of the positioning arc due to its own elastic force, generating a certain friction force, thereby achieving connection between the placement plate and the support plate for easy installation. After overcoming the friction force, the placement plate can be removed from the support plate to facilitate cleaning of each placement plate. Compared with the traditional whole table top, cleaning is more convenient and labor-saving.

[0010] As a preferred solution of the utility model, both ends of the placement plate are provided with guiding slopes, and one end of the guiding slope close to the support plate has an arc-shaped protective surface.

[0011] By implementing the above technical solution, the soup on the dish can be easily dripped along the guiding inclined surface, and the setting of the arc-shaped protective surface enhances the protection effect on people and is not easy to produce a cutting feeling.

[0012] As a preferred solution of the utility model, a positioning tube is sleeved on the cross bar, a clamping plate and an elastic clamping ring are fixedly connected to the outer wall of the positioning tube, a positioning groove is provided on the lower surface of the support plate, the clamping plate is embedded in the positioning groove, and a notch is provided on the side of the elastic clamping ring facing away from the positioning tube.

[0013] To implement the above technical solution, the two support frames are folded in half, and the cross bar can be embedded into the elastic clamp from the notch. The elastic force of the elastic clamp itself can reset the notch and position the cross bar, so as to achieve a fixed connection between the two cross bars, which is convenient for carrying the long table.

[0014] As a preferred solution of the utility model, the end of the notch has an arc-shaped guiding surface.

[0015] To implement the above technical solution, the cross bar can easily open the gap along the arc-shaped guide surface. After the cross bar is embedded in the elastic clamping ring, the gap becomes smaller due to the elastic force of the elastic clamping ring itself, thereby achieving the positioning of the cross bar.

[0016] As a preferred solution of the utility model, the lower surface of the support plate is provided with a placement groove, a straight groove and an oblique groove, the support leg is flipped along the cross bar and placed in the placement groove, the rotating rod is placed in the oblique groove, and the connecting rod is placed in the straight groove.

[0017] To implement the above technical solution, the two support frames are folded in half, the support legs are flipped along the cross bar and placed in the placement grooves, the rotating rods are placed in the oblique grooves, and the connecting rods are placed in the straight grooves to reduce the space occupied and facilitate transportation.

[0018] As a preferred solution of the utility model, a plurality of elastic blocks are fixedly connected to the lower surface of the support plate, and a stabilizing plate is fixedly connected to the support leg, and the stabilizing plate is used to abut against the ends of the elastic blocks.

[0019] By implementing the above technical solution, the stabilizing plate can improve the structural stability of the supporting legs, and the elastic blocks support the stabilizing plate so that the stabilizing plate is not easily bent during transportation.

[0020] As a preferred solution of the utility model, an elastic buffer block is fixedly connected to the lower surface of the support plate, and the two support frames rotate along the pin shaft to make the two opposite elastic buffer blocks collide with each other.

[0021] To implement the above technical solution, the provision of the elastic buffer block enhances the protective effect on the support frame. BRIEF DESCRIPTION OF THE DRAWINGS
