Description

Technical Field

[0001] The utility model relates to the field of extendable tables and relates to an extendable table. Background Art

[0002] An extendable table is a piece of furniture designed to increase the length of the tabletop as needed. Such tables are commonly used in homes, offices, meeting places, or restaurants to adapt to different space and number of people requirements. Conventional table designs on the market are usually fixed, with the length and width of the tabletop preset, which limits their applicability in different occasions.

[0003] Therefore, in order to solve the deficiencies in the prior art, it is necessary to design an extendable table with a simple structure. Summary of the Utility Model

[0004] The utility model provides an extendable table to solve the problems of the prior art.

[0005] The purpose of the utility model can be achieved by the following technical solutions: An extendable table includes: a fixed tabletop, tracks, a sliding frame, table legs, and an extended tabletop. The tracks are symmetrically fixed to the lower end of the fixed tabletop. The sliding frame includes a support frame and a sliding rod. The sliding rod is fixed to the inner side of the support frame and one end is slidably arranged in the sliding frame. The table legs are fixed to the ends of the support frame. The extended tabletop includes a tabletop, a limiting frame, a first limiting wheel, and a top rod. The limiting frame is fixed to the lower end of the tabletop. The first limiting wheel is rotatably arranged at the lower end of the limiting frame. The top rod is fixed to the front end of the limiting frame. A horizontal rib is provided in the middle of the support frame inside the first limiting wheel. A second limiting wheel is provided on the horizontal rib. The second limiting wheel is arranged inside the vertical rib of the limiting frame. A convex rod is provided at the end of the support frame. The convex rod is located outside the top rod.

[0006] Further improvement: An arc-shaped sliding rod channel is provided outside the track. A first guide wheel channel communicates with the inside of the arc-shaped sliding rod channel. A first guide wheel is provided inside the first guide wheel channel. A threaded locking rod is provided above the inside of the arc-shaped sliding rod channel.

[0007] Further improvement: The sliding rod is slidably arranged in the arc-shaped sliding rod channel. A second guide wheel channel is provided inside the sliding rod. A second guide wheel is provided inside the second guide wheel channel.

[0008] Further improvement: A strengthening adjustment rod is provided on the threaded locking rod.

[0009] Further improvement: Four groups of the first limiting wheels are symmetrically arranged. Two groups of the second limiting wheels are symmetrically arranged.

[0010] Compared with the prior art, the stretching table of the utility model has the following beneficial effects: when there is no need to increase the usable area of the table top, the table top in the extended table top is hidden under the fixed table top, and the table top is placed on the upper end of the support frame, and the limiting wheels 1 of the limiting frame of the table top are clamped on both sides of the horizontal ribs of the support frame, and the limiting wheels 2 of the support frame are clamped on the inner sides of the vertical ribs of the limiting frame to achieve stable placement; when it is necessary to increase the usable area of the table top, the table legs are pulled outward together with the sliding frame simultaneously, and the sliding rod is pulled outward from the track, and the table top and the limiting frame are taken out from the upper end of the support frame. After the rotation degree, the table top area is larger than the support frame area, and after the table top is placed on the pulled out sliding rod, the top rod at the front end of the limiting frame at the lower end supports the convex rod, and then the sliding frame pushes back to clamp the table top, so as to achieve double-sided area extension, which is simple to operate and easy to use.

[0021] Embodiment 1

[0022] A stretching table, comprising: a fixed tabletop 1, tracks 2, a sliding frame 3, table legs 4, and an extended tabletop 5. The tracks 2 are symmetrically fixed to the lower end of the fixed tabletop 1. The sliding frame 3 includes a support frame 31 and a sliding rod 32. The sliding rod 32 is fixed to the inner side of the support frame 31 and one end is slidably disposed within the sliding frame 3. The table legs 4 are fixed to the end of the support frame 31. The extended tabletop 5 includes a tabletop 51, a limiting frame 55, a first limiting wheel 52, and a top rod 53. The limiting frame 55 is fixed to the lower end of the tabletop 51. The first limiting wheel 52 is rotatably disposed at the lower end of the limiting frame 55. The top rod 53 is fixed to the front end of the limiting frame 55. A horizontal rib 33 is provided in the middle of the support frame 31 inside the first limiting wheel 52. A second limiting wheel 34 is provided on the horizontal rib 33. The second limiting wheel 34 is disposed inside the vertical rib 54 of the limiting frame 55. A convex rod 35 is provided at the end of the support frame 31. The convex rod 35 is located outside the top rod 53.

[0023] As Figures 1 to 6 shown, the working principle of the present utility model: When there is no need to increase the usable area of the tabletop, as Figure 1 shown, the back structure is as Figure 3 shown. The tabletop 51 in the extended tabletop 5 is hidden below the fixed tabletop 1. The tabletop 51 is placed on the upper end of the support frame 31. The first limiting wheels 52 of the limiting frame 55 of the tabletop 51 are stuck on both sides of the horizontal rib 33 of the support frame 31. The second limiting wheels 34 of the support frame 31 are stuck inside the vertical rib 54 of the limiting frame 55 to achieve stable placement. When it is necessary to increase the usable area of the tabletop, as Figure 2 shown, the back structure is as Figure 4As shown, pull out the table legs 4 and the sliding frame 3 synchronously. The sliding rod 32 is pulled out from the inside of the track 2. After taking out the tabletop 51 and the limiting frame 55 from the upper end of the support frame 31 and rotating them by 90 degrees, the area of the tabletop 51 is larger than that of the support frame 31. After the tabletop 51 is placed on the pulled-out sliding rod 32, the ejector rod 53 at the front end of the limiting frame 55 at the lower end presses against the convex rod 35, and then the sliding frame 3 is pushed back to clamp the tabletop 51, realizing the extension of the bilateral area. The operation is simple and the use is convenient.

[0024] As a further preferred embodiment, an arc-shaped sliding rod channel 21 is provided outside the track 2. The inside of the arc-shaped sliding rod channel 21 is communicated with a first guide wheel channel 22. A first guide wheel 23 is provided inside the first guide wheel channel 22. A threaded locking rod 24 is provided above the inside of the arc-shaped sliding rod channel 21. By means of the internally provided guide wheels, the friction force is reduced during the movement process, making it more labor-saving.

[0025] As a further preferred embodiment, the sliding rod 32 is slidably arranged in the arc-shaped sliding rod channel 21. A second guide wheel channel 321 is provided inside the sliding rod 32. A second guide wheel 322 is provided inside the second guide wheel channel 321. By means of the internally provided guide wheels, the friction force is reduced during the movement process, making it more labor-saving.

[0026] As a further preferred embodiment, a reinforcing adjusting rod 25 is provided on the threaded locking rod 24. By means of the reinforcing adjusting rod 25, the rotation convenience of the threaded locking rod 24 is improved, and the sliding rod 32 located in the arc-shaped sliding rod channel 21 is clamped and fixed by rotating the threaded locking rod 24.

[0027] As a further preferred embodiment, four groups of the first limiting wheels 52 are symmetrically arranged, and two groups of the second limiting wheels 34 are symmetrically arranged. By means of multiple groups of the first limiting wheels 52 and the second limiting wheels 34, the limiting effect is improved.

[0028] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations according to the concept of the present invention without creative labor.
