Description

Technical Field

[0001] This utility model application relates to the field of folding table technology, specifically a length-adjustable folding table. Background Technology

[0002] A folding table is a portable piece of furniture that uses hinges, slides, or folding structures to unfold or retract its tabletop or support components. Its core feature is its flexible shape to save space. It is usually made of wood, metal, or plastic and its structure includes foldable legs, telescopic supports, or a folding tabletop. When unfolded, it provides a stable surface, and when folded, it reduces the area it occupies. It is widely used in homes, offices, and outdoors to meet temporary dining, working, or storage needs. Its advantages include ease of transport, multi-functional adaptability, and efficient use of space. Common types include folding stand tables, telescopic tables, and wall-mounted folding tables. It is a modern living solution that combines practicality and convenience.

[0003] Traditional folding tables typically slide one tabletop underneath the other. This means that when the tabletop is unfolded, its top surface cannot be flat. This requires users to consider the height difference at the seam between the two tabletops when using the folding table. Additionally, this storage method makes the lower tabletop prone to wear and tear when frequently pulled out, causing damage to the tabletop. Summary of the Invention

[0004] To address the issue of height differences at the seams between the two tabletops of traditional folding tables, which also makes the lower tabletop surface prone to wear, this invention provides a length-adjustable folding table to solve the aforementioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An adjustable-length folding table includes a first tabletop, a first support frame fixed below the first tabletop, two fixed plates symmetrically fixed to one end of the bottom surface of the first tabletop, a second support frame disposed on the side of the first support frame near the fixed plates, sliding devices fixed on both sides of the second support frame and the fixed plates, a connecting plate fixed to the side of the second support frame near the first tabletop, a rotating block fixed between the connecting plate and the second support frame, two second tabletops symmetrically disposed on one side of the first tabletop, the two second tabletops being rotatably connected by a connecting hinge, two rotating blocks symmetrically fixed to the bottom end of one second tabletop, both of the rotating blocks being slidably connected to a connecting rod, a support plate fixed to the bottom end of the connecting plate, two table legs fixed to the bottom end of the first support frame, and two more table legs symmetrically fixed to the side of the second support frame away from the first support frame.

[0007] Furthermore, the first tabletop has bevels on all four sides, and the second tabletop has bevels on its sides that are the same shape as the first tabletop.

[0008] Furthermore, the sliding device includes a first slide rail, which is fixedly connected to a fixed plate. The first slide rail is slidably disposed inside a second slide rail. A third slide rail is slidably disposed on the side of the second slide rail away from the first slide rail. The third slide rail is fixedly connected to a second support frame.

[0009] Furthermore, the connecting rod is rotatably connected to the rotating block, and the rotating block near the second support frame is in contact with the second support frame.

[0010] Furthermore, the connecting plate is provided with a groove that matches the shape of the fixed plate, and the support plate and the connecting rod are symmetrically arranged below the two second tabletops.

[0011] Furthermore, a connecting block that matches the angle of the inclined surface of the first tabletop is fixed at the joint between the second tabletop and the first tabletop, and the top surfaces of the first tabletop and the second tabletop are on the same plane.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, by sliding the second support frame to the fixed plate via a sliding device, and then folding the two second tabletops, the second tabletops are rotated so that they rotate on the connecting rod via a rotating block to the bottom of the first tabletop. At the same time, the support plate supports the folded second tabletops. Then, by pushing the second support frame, the second support frame can slide towards the first tabletop. At this time, the second support frame moves the second tabletops to the bottom of the first tabletop, which solves the problem of height difference at the joint between the two tabletops of the traditional folding table, and also makes the bottom tabletop surface easy to wear.

[0014] 2. In this utility model, both the outer sides of the first tabletop and the second tabletop are provided with inward slopes. At the same time, a connecting block that matches the shape of the slope of the first tabletop is provided at the connection between the second tabletop and the first tabletop. This makes the two seams fit together when the second tabletop is unfolded and combined with the first tabletop, making the connection between the second tabletop and the first tabletop more neat and improving the flatness of the top surface of the first tabletop and the second tabletop after they are assembled.

Detailed Implementation

[0021] To make the purpose, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4An adjustable-length folding table includes a first tabletop 1, a first support frame 2 fixed below the first tabletop 1, two fixed plates 6 symmetrically fixed at one end of the bottom surface of the first tabletop 1, a second support frame 5 arranged on the side of the first support frame 2 near the fixed plates 6, sliding devices 7 fixed on both sides between the second support frame 5 and the fixed plates 6, a connecting plate 11 fixed on the side of the second support frame 5 near the first tabletop 1, a rotating block 10 fixed between the connecting plate 11 and the second support frame 5, two second tabletops 3 symmetrically arranged on one side of the first tabletop 1, the two second tabletops 3 being rotatably connected by a connecting hinge 4, two rotating blocks 10 symmetrically fixed at the bottom of one second tabletop 3, both rotating blocks 10 being slidably connected to a connecting rod 9, a support plate 8 fixed at the bottom of the connecting plate 11, two table legs 12 fixed at the bottom of the first support frame 2, and two other table legs 12 symmetrically fixed on the side of the second support frame 5 away from the first support frame 2, so that there is no seam or height difference at the connection between the first tabletop 1 and the second tabletop 3.

[0023] Specifically, the sliding device 7 includes a first slide rail 71, which is fixedly connected to the fixed plate 6. The first slide rail 71 is slidably disposed inside the second slide rail 72. A third slide rail 73 is slidably disposed on the side of the second slide rail 72 away from the first slide rail 71. The third slide rail 73 is fixedly connected to the second support frame 5. The connecting rod 9 is rotatably connected to the rotating block 10. The rotating block 10 near the second support frame 5 is in contact with the second support frame 5. The connecting plate 11 has a groove that matches the shape of the fixed plate 6. The support plate 8 and the connecting rod 9 are symmetrically disposed below the two second tabletops 3 to facilitate the sliding of the connecting plate 11 below the first tabletop 1.

[0024] As an optimization solution, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the first tabletop 1 has beveled surfaces on all four sides, and the second tabletop 3 has beveled surfaces of the same shape as the first tabletop 1 on its side, so as to facilitate the splicing of the first tabletop 1 and the second tabletop 3.

[0025] Specifically, a connecting block that matches the angle of the slope of the first tabletop 1 is fixed at the joint between the second tabletop 3 and the first tabletop 1. The top surfaces of the first tabletop 1 and the second tabletop 3 are on the same plane, making the joint between the first tabletop 1 and the second tabletop 3 more complete.

[0026] Working principle: When the second tabletop 3 needs to be stored, pulling the second support frame 5 outward causes it to slide with the first support frame 2 via the sliding device 7, thus disengaging the second tabletop 3 from the first tabletop 1. Then, by moving one side of the second tabletop 3, it rotates via the connecting hinge 4, allowing the two second tabletops 3 to stack together. Moving the two second tabletops again causes the bottom of the other second tabletop 3 to rotate via the rotating block 10 and connecting rod 9, thus flipping the two second tabletops 3. At this point, the support plate 8 supports the two second tabletops 3. Finally, pushing the second support frame 5 causes it to move the connecting rod... 9 moves downwards from the first tabletop 1. Simultaneously, the connecting rod 9, through the rotating block 10, drives the two second tabletops 3 to move downwards from the first tabletop 1. At the same time, the second support frame 5 drives the connecting plate 11 and the supporting plate 8 to move downwards from the first tabletop 1, thus completing the storage of the second tabletops 3. When the second tabletops 3 need to be joined with the first tabletop 1, the second tabletops 3 are restored by reversing the operation. Then, by pushing the second support frame 5, the second support frame 5 drives the rotating block 10 to move, thereby causing the rotating block 10 to move the two second tabletops 3, so that the second tabletops 3 and the first tabletop 1 can be joined together. Furthermore, the inclined surface at the connection between the first tabletop 1 and the second tabletops 3 makes the joint between the first tabletop 1 and the second tabletops 3 more neat.
