Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and more specifically, it relates to a telescopic table with easily replaceable panel strips. Background Technology

[0002] Traditional tables are fixed in shape after they are made. They cannot be extended or retracted, and have the disadvantages of taking up a large area and being inconvenient to move or unable to be extended when the tabletop needs to be expanded. To solve the above problems, a table with extension capabilities has appeared on the market.

[0003] Chinese patent CN211323488U discloses a telescopic table, which includes two table leg assemblies arranged opposite each other, and multiple panel strips disposed between the two table leg assemblies. The table leg assembly is generally inverted U-shaped, including two table legs and a crossbeam disposed between the tops of the two table legs. Two telescopic beams are disposed between the two table leg assemblies. The upper end face of the telescopic beam is provided with a sliding groove, and the sliding groove is provided with a chain structure. The chain structure includes multiple sliders that slide and cooperate with the sliding groove, and a spacing limiting plate disposed between adjacent sliders.

[0004] The above technical solution has a more stable overall structure, and the movement of each panel strip is restricted, effectively eliminating the risk of loosening. The spacing between multiple panel strips is more consistent after unfolding, which effectively improves the aesthetics. However, in actual use, when it is necessary to replace a single panel strip by unscrewing the bolts, it will damage the chain structure, thereby affecting the overall stability of the telescopic table and making the replacement of panel strips inconvenient.

[0005] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Utility Model Content

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively. Specific Implementation Example 2:

[0023] As shown in the figure, a telescopic table with easy-to-replace panel strips includes two sets of oppositely arranged table leg groups 1. The table leg group 1 is inverted U-shaped and includes two table legs 2 and a crossbeam 3 set between the tops of the two table legs 2. Two telescopic beams 4 are arranged between the two table leg groups 1. The telescopic beam 4 includes an outer beam 5 and an inner beam 6 slidably connected to its inner sidewall. The upper surfaces of the outer beam 5 and the inner beam 6 are provided with grooves along their length. A chain structure is provided in the groove (the chain structure has been disclosed in the prior art and will not be described in detail in this embodiment). The chain structure includes several sliders 7 that slide in the groove. The top of the slider 7 extends to one side to form a connecting part 9. The connecting parts 9 of the two sliders 7 are detachably connected to the panel strips 8 by positioning members.

[0024] The connecting part 9 has a through hole 10 that penetrates its upper and lower surfaces. The two ends of the lower surface of the panel strip 8 have screw holes 11 corresponding to the through hole 10. The positioning element is a bolt (not shown in the figure) set in the through hole 10 and the screw hole 11.

[0025] The panel strip 8 and the two connecting parts 9 can be easily fixed with bolts. Unscrewing the bolts will not damage the integrity of the chain structure, so it is easy to replace a single panel strip 8. Specific Implementation Example 2:

[0027] Unlike specific embodiment 1, the positioning component includes two sliding blocks 12 that are slidably connected to the lower surface of the panel strip 8. A connecting part 9 extends from the top of the sliding block 12 to the side of the sliding block 12. A limiting rod 13 is provided on the side of the connecting part 9 facing the sliding block 12. The sliding block 12 has a limiting groove 14 for the limiting rod 13 to be inserted. It also includes a driving component for driving the two sliding blocks 12.

[0028] The sliding block 12 is controlled to slide at the bottom of the panel strip 8 by the driving component. When the two sliding blocks 12 are controlled to slide toward the two connecting parts 9 respectively, the limiting rod 13 is inserted into the limiting groove 14 to fix the connecting part 9 and the panel strip 8. When the two sliding blocks 12 are driven to move relative to each other, the limiting rod 13 is separated from the limiting groove 14, and the panel strip 8 can be disassembled.

[0029] Two T-slots are formed on the lower surface of the panel strip 8. A T-block 15 is provided on the top of the sliding block 12 and slides within the T-slot. A spring 16 is fixedly connected between the T-block 15 and the inner wall of the end of the T-slot. The driving component is used to drive the two sliding blocks 12 to slide relative to each other. Under the elastic force of the spring 16, the sliding block 12 is pressed against the connecting part 9, and at the same time, the limiting rod 13 is inserted into the limiting groove 14 to ensure the stability of the panel strip 8 during installation.

[0030] Guide rods 17 are fixedly connected to the opposite sides of the two T-shaped blocks 15. One end of the T-shaped groove is provided with a guide groove for the guide rods 17 to be inserted and slidably connected. Spring 16 is sleeved on the guide rods 17 to ensure the normal sliding operation of the sliding block 12.

[0031] The driving component includes a knob 18 rotatably connected to the center of the lower surface of the panel strip 8. Pull cords 19 are fixedly connected to both sides of the knob 18, and the other ends of the pull cords 19 are fixedly connected to two sliding blocks 12. By rotating the knob 18, the two pull cords 19 are wound around the circumferential sidewall of the knob 18, thereby pulling the two sliding blocks 12 to slide relative to each other. The spring 16 is compressed, causing the limiting rod to separate from the limiting groove 14, thus separating the panel strip 8 from the connecting part 9 for disassembly and assembly of the panel strip 8.

[0032] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
