Description

Technical Field

[0001] The utility model relates to the technical field of daily tables, in particular to a folding table frame. Background Art

[0002] Nowadays, people pay attention to healthy lifestyles and like to participate in various outdoor leisure activities, such as outdoor camping and picnics. Because they can increase exercise and improve mood, they are deeply loved by people. In these activities, folding tables that are easy to carry and store are inevitably used. Since the tabletop and table legs of this folding table can be folded, the folded volume is small and can be easily put into a vehicle. The folding table currently used mainly includes a folding frame as a core component. The folding frame generally includes a main beam for rotating the tabletop and a support leg that can be folded to connect the main beam. In order to make the folding frame structure stable after unfolding, it also includes a connecting rod that can be folded and connected to the main beam and the support leg. When storing, the support leg and the connecting rod are folded inward, so that the folding frame can be folded into a bundle. However, since this folding frame lacks a locking mechanism after unfolding, it is difficult to avoid the unintentional folding and storage caused by the inward collision of the support leg and the connecting rod during use. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a folding table stand which has a simple structure, is easy to use and can be locked after being unfolded.

[0006] Furthermore, a longitudinal hinge shaft is provided on the inner side of the side beam, one end of the push rod is sleeved on the longitudinal hinge shaft, and the free end of the push rod can be horizontally opened and closed around the longitudinal hinge shaft.

[0007] Furthermore, there are two top rods, which are respectively hinged to the two ends of the same side beam.

[0008] Furthermore, there are two top rods, which are cross-hinged to one end of the two side beams respectively.

[0020] refer to Figures 1 to 6As shown, a folding table frame is shown, including two side beams 1 arranged opposite to each other, two supporting legs 2 are foldably installed under the two side beams 1, cross connecting rods 3 are rotatably connected between the supporting legs 2 and the side beams 1 in pairs, and a top rod 4 is rotatably connected to the inner side of the side beam 1, and the free end of the top rod 4 can be pressed against the side beam 1 on the opposite side.

[0021] As shown in the attached figure, when the folding frame is fully opened, each side beam 1 and the two legs 2 thereon form a stable support structure, and the cross connecting rod 3 is cross-connected with the outer ends of the two side beams 1 and the middle parts of the two legs 2 respectively, and the two ends of the top rod 4 are respectively pressed against the inner sides of the two side beams 1, so that a folding frame that can withstand a certain downward pressure is formed, and a panel 5 can be installed on the top of the folding frame, which can be used as a table. When it is necessary to fold and store, the free end of the top rod 4 is rotated toward the inner side of the side beam 1, so that the top rod 4 is close to the side beam 1 along the length direction, and then the legs 2 at both ends of the folding frame are pushed toward the center, and the two side beams 1 are also moved closer to each other while the legs 2 are folded, until all the parts are folded into a bundle, which is very convenient for storage and transportation.

[0022] When the folding frame is unfolded and used, since the top rod 4 is pressed against the two side beams 1 on the opposite sides, when the supporting feet 2 are accidentally hit to cause them to generate a force to fold inwards, the top rod 4 limits the distance between the two side beams 1. The two side beams 1 cannot overcome the pressing force of the top rod 4, and thus cannot achieve the folding action of moving closer to each other, thereby playing a locking folding role, thereby ensuring the overall structural stability of the folding frame during use.

[0023] Furthermore, a longitudinal hinge shaft 41 is provided inside the side beam 1 , one end of the push rod 4 is sleeved on the longitudinal hinge shaft 41 , and the free end of the push rod 4 can be horizontally opened and closed around the longitudinal hinge shaft 41 .

[0024] As shown in the attached drawings, there are L-shaped mounting strips 11 on the inner side of the two side beams 1, with the horizontal side of the mounting strips 11 at the top, which can be used to lay the table top flat. The longitudinal hinge shaft 41 can be directly fixed on the side beam 1, or fixed on the longitudinal side of the mounting strip 11. After one end of the top rod 4 is sleeved on the longitudinal hinge shaft 41, it rotates around the longitudinal hinge shaft 41 to open and close. When opened, its free end presses against the inner side of the opposite side beam 1 to play a locking role. When folding is required, the top rod 4 can be manually rotated to rotate and store it inside the side beam 1 to release the lock.

[0025] Furthermore, there are two top rods 4 , which are respectively hinged to the two ends of the same side beam 1 .

[0026] As shown in the attached drawings, two push rods 4 act on both ends of the folding frame at the same time, and the force is evenly applied, making the square frame more stable. During use, whether it is subjected to external force on one side or both sides, it can play a strong anti-deformation effect. The longitudinal hinge shaft 41 hinged to each push rod 4 is respectively at both ends of the same side beam 1. When it is necessary to rotate and fold, the operator can simultaneously rotate the two push rods 4 to the inside of the same side beam 1, which is simple and convenient to operate.

[0027] Furthermore, there are two top rods 4 , which are cross-hinged to one end of the two side beams 1 .

[0028] As shown in the drawings, the longitudinal hinge shaft 41 hinged to each top rod 4 is respectively at one end of the two side beams 1, that is, the installation structure of each side beam 1 and the top rod 4 is the same, so it is more convenient for mass production, processing and assembly of the folding frame.

[0029] Furthermore, a limiting slot 12 is provided on the inner side of the side beam 1 , and the free end of the push rod 4 can be movably mounted in the limiting slot 12 .

[0030] As attached Figure 6 As shown, the opening of the limit slot 12 faces the foldable side of the push rod 4, so that the push rod 4 can be accurately inserted into the opposite limit slot 12 when it is unfolded, to prevent it from rotating in the opposite direction and failing to accurately press against the side beam 1. When it is stored, it can also be limited to come out of the limit slot 12, making the operation easier.

[0031] Furthermore, an elastic clip 13 capable of clamping the folded top rod 4 is provided on the inner side of the side beam 1 .

[0032] As attached Figure 5 As shown, the elastic clip 13 is an open clip, which can be located at the overlapping part where the top rod 4 is folded to the inner side of the side beam 1, and its opening faces the opposite side beam 1. When the top rod 4 is folded, it can be directly inserted into the clip 13 to form an integrated structure with the side beam 1, which makes it more convenient to fold the support leg 2.
