Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of furniture, in particular to a lifting and drawing table. BACKGROUND

[0002] In daily life, the traditional fixed desktop table is widely welcomed due to its stability and convenience. However, with the diversification of living space and the continuous change of use requirements, the limitations of fixed desktops are increasingly prominent. Especially when the placement space or use occasion of the table changes, such as moving from a large room to a small room, or the number of diners increases, the fixed desktop often cannot flexibly adapt to these changes, bringing many inconveniences to users.

[0003] In order to overcome this limitation, the furniture manufacturing industry has begun to explore and produce some new types of furniture, among which the lifting and drawing table is a very representative one. Compared with the traditional fixed desktop table, the lifting and drawing table realizes flexible change of the size of the desktop in design, so as to make full use of the space. This kind of table is usually equipped with precise mechanical structure, such as steel ball sliding rail, etc., which drives the side desktop to move synchronously through the sliding rail to realize the lifting and drawing function of the desktop.

[0004] However, although the lifting and drawing table has made significant progress in design and function, there are still some problems to be solved in the existing design. In particular, the application of steel ball sliding rail, although it improves the smoothness and stability of the operation of the table to a certain extent, also brings some limitations.

[0005] First of all, the steel ball sliding rail is installed inside the table frame, and its pulling stroke is directly limited by the size of the table frame. This means that the expansion range of the desktop is strictly limited by the physical space, and cannot be expanded infinitely according to the actual needs. When the user needs to place the table in a smaller space, or needs a larger desktop space to accommodate more people or objects, this limitation is particularly prominent.

[0006] Secondly, due to the limitation of sliding rail stroke, the size of the middle desktop is usually smaller than that of the side desktops. Although this design ensures the stability of the structure of the table and the convenience of operation to a certain extent, it also limits the overall expansion ratio of the table after the desktop is unfolded. In actual use, users may find that even if the desktop is fully unfolded, it cannot meet the spacious space required for specific work or activities, thereby affecting the practicability and user experience of the table.

[0060] Wherein, two side table plates 12 are pulled to the two sides of the middle table plate 11, two sliding rail corners 23 slide on the sliding main rail 21 to the two sides of the middle table plate 11, when the sliding rail corners 23 slide from the upper guide groove 221 to the lower guide groove 222 through the inclined guide groove 223, the middle table plate 11 on the sliding sub-rail 22 rises relative to the side table plate 12, then the two sliding rail corners 23 slide in the corresponding lower guide groove 222 to drive the two side table plates 12 to slide to be horizontally aligned with the middle table plate 11, so that the lifting pull-out table is in an unfolded state; two side table plates 12 are pulled in reverse, two sliding rail corners 23 slide on the sliding main rail 21 towards the middle table plate 11, when the sliding rail corners 23 slide from the lower guide groove 222 to the upper guide groove 221 through the inclined guide groove 223, the middle table plate 11 on the sliding sub-rail 22 falls relative to the side table plate 12, then the two sliding rail corners 23 slide in the upper guide groove 221 to drive the two side table plates 12 to slide above the middle table plate 11, so that the lifting pull-out table is in a storage state.

[0061] The lifting pull-out table of the utility model expands the table space when needed, and meets the demand of simultaneous use of multiple people.

[0062] When the large table surface is not needed, the two side table plates 12 are pulled in reverse, when the two sliding rail corners 23 slide from the lower guide groove 222 to the upper guide groove 221 through the inclined guide groove 223, the middle table plate 11 on the sliding sub-rail 22 falls relative to the side table plate 12, then the two sliding rail corners 23 slide in the upper guide groove 221 to drive the two side table plates 12 to slide above the middle table plate 11, so that the lifting pull-out table is in a storage state, which reduces the placing space and meets the demand of simultaneous use of a few people.

[0063] Further, the lifting and pulling table of the utility model, through setting two slide rail angle surfaces 23 between the sliding main rail 21 and the sliding auxiliary rail 22, the pulling stroke of the side table plate 12 on the sliding main rail 21 is increased, the side table plate 12 can slide in a larger range, so that the side table plate 12 can form a larger expansion ratio with the middle table plate 11 when pulled apart, so that the specification of the large-size middle table plate 11 is realized, so that the lifting and pulling table can cover a wider area in the unfolded state, and further more flexibly adapt to different use spaces and scenes.

[0064] In the embodiment, as shown in Figures 4-6 Two sliding positioning pins 231 are arranged on each of the two slide rail angle surfaces 23, the slide rail angle surface 23 slides on the sliding main rail 21, drives the sliding positioning pin 231 to switch between the upper guide groove 221 and the lower guide groove 222 through the inclined guide groove 223. The sliding positioning pin 231 can smoothly slide from the upper guide groove 221 to the lower guide groove 222 through the inclined guide groove 223, the side table plate 12 slides to be horizontally aligned with the middle table plate 11, or slides from the lower guide groove 222 to the upper guide groove 221, so that the middle table plate 11 is located below the side table plate 12, thereby realizing the smooth lifting of the middle table plate 11.

[0065] In the embodiment, as shown in Figures 1-5 The slide rail angle surface 23 extends to the outside of the support frame structure 3. The support frame structure 3 is in the shape of a rectangle, the support frame structure 3 comprises two side table frames 31 and two connecting beams 32 arranged between the two side table frames 31, and is enclosed by the two side table frames 31 and the two connecting beams 32, two groups of pulling and lifting structures 2 are arranged on the inner sides of the two side table frames 31 respectively, and the two groups of pulling and lifting structures 2 are arranged in parallel. The support frame structure 3 composed of the two side table frames 31 and the two connecting beams 32 provides a stable support foundation, ensuring the stability and safety of the pulling and lifting structure 2 during use.

[0066] In the embodiment, as shown in Figures 1-3 Two groups of leg structures 4 are further arranged on the two sides of the support frame structure 3. The leg structure 4 is a mouth-shaped foot pipe structure. The leg structure 4 is a mouth-shaped foot pipe structure, which can effectively disperse and bear the weight and pressure from the support frame structure 3, ensuring the stability of the whole structure.

[0067] In the embodiment, as shown in Figure 1 , 2The connecting beam 32 is provided with a first pulley 321, and the bottom of the side table plate 12 is provided with a first sliding groove 121 for sliding the first pulley 321. When the slide rail corner surface 23 drives the side table plate 12 to slide, the first pulley 321 slides in the first sliding groove 121. The connecting beam 32 is provided with a fixing seat 322, and the first pulley 321 is arranged on the connecting beam 32 through the fixing seat 322. When the two side table plates 12 slide left and right towards the two sides of the middle table plate 11, the first pulley 321 slides in the first sliding groove 121, so that the side table plate 12 can move stably, effectively limiting the shaking of the side table plate 12 in the horizontal direction, and effectively preventing the left and right shaking and sinking of the table top, thereby improving the stability and durability of the entire lifting and pulling table.

[0068] In the embodiment, as shown in Figure 1 , 4 The slide rail corner surface 23 extends to the outside of the side table frame 31. In this way, the slide rail stroke of the side table plate 12 is further increased, the side table plate 12 can slide inward or outward by a larger distance, and a larger size middle table plate 11 can be supported, so that the middle table plate 11 can reach a size almost equal to the side table plate 12 after stretching, or even larger, further improving the expansion ratio of the table top and meeting the user's demand for a spacious working area.

[0069] In the embodiment, the slide main rail 21 is provided with a second pulley and a steel wire rope connected with the second pulley, and the steel wire rope is used to connect the two side table plates 12 arranged on the two slide rail corner surfaces 23. By connecting the two side table plates 12 with the steel wire rope, it can be ensured that the two side table plates 12 move synchronously, and when one side table plate 12 moves, the other side table plate 12 also moves at the same speed and distance, thereby avoiding the misalignment or unevenness between the table tops and reducing the shaking of the side table plate 12 during sliding.

[0070] In the embodiment, as shown in Figure 7 The bottom of the side table plate 12 is provided with a scratch-proof pulley 122. Preferably, the number of scratch-proof pulleys 122 is two, which are arranged at the two side edges of the bottom of the side table plate 12 and close to the middle table plate 11. When the side table plate 12 is in the storage state, the scratch-proof pulley 122 will lightly press above the middle table plate 11, providing a uniform supporting force for the middle table plate 11, effectively preventing the deformation of the table top caused by long-term vacancy or improper storage. When the side table plate 12 is pulled out, the scratch-proof pulley 122 will roll on the middle table plate 11, and the rolling contact significantly reduces the frictional resistance, making the movement of the side table plate 12 more smooth and convenient, and preventing the middle table plate 11 from being easily scratched by the side table plate 12.

[0071] In summary, the lifting and pulling table has the following advantages:

[0072] (1) State switching is convenient: by pulling the side table plate 12, the switching between the storage and expansion states is realized, and different use scenarios can be met.

[0073] (2) Realize large size middle table top: two slide rail angle faces 23 are arranged between the sliding main rail 21 and the sliding sub-rail 22, and the slide rail angle face 23 extends to the outside of the side table frame 31, which greatly increases the pulling stroke of the side table plate 12 on the sliding main rail 21, so that the middle table plate 11 can reach almost the same size as the side table plate 12 after stretching, or even larger, and the table top expansion ratio is improved.

[0074] (3) High stability: the leg structure 4 is a mouth-shaped foot pipe structure, which can effectively disperse and bear the weight and pressure from the support frame structure 3, and ensure the stability of the lifting and pulling table in the expanded state.

[0075] (4) Avoid scratching the middle table plate: the bottom of the side table plate 12 is provided with a scratch-proof pulley 122 to prevent the bottom of the side table plate 12 and the upper part of the middle table plate 11 from rubbing, avoid scratching the upper surface of the middle table plate 11, and prevent the table top from deforming.

[0076] (5) Synchronous sliding: the two side table plates 12 are connected by steel wires, which can ensure that the two side table plates 12 remain synchronous when sliding.

[0077] Therefore, the utility model effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0078] The above embodiments only exemplarily illustrate the principles and effects of the utility model, and are not used to limit the utility model. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the utility model. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought disclosed by the utility model should be covered by the claims of the utility model.
