Description

Technical Field

[0001] The utility model belongs to the technical field of pull-out tables, and in particular relates to an automatically lifting pull-out table. Background Art

[0002] A pull-out table is a table that raises and lowers the secondary tabletop by pulling out the main tabletop, which drives the bearing slide or steel ball slide to slide. This allows for the variability of the tabletop size and is suitable for different usage scenarios. When there are fewer people, it can be retracted to reduce the floor space. When there are more people, the hidden tabletops can be spliced ​​together by pulling to achieve a larger usable area. It is widely favored by people due to its wide range of applications. During the stretching process of existing pull-out tables, the tabletop generally moves outward while the legs do not move. After the tabletop is extended, the distance between the legs remains unchanged, and the tabletop is prone to force imbalance, resulting in structural instability. In order to ensure force balance, the size of the secondary tabletop cannot be too large, and the size of the tabletop is limited after it is extended. Utility Model Content

[0024] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of an automatic lifting pull-out table of the present invention in conjunction with the accompanying drawings.

[0025] like Figure 1 Figure 2 As shown, the utility model is an automatic lifting and pulling table, including a main desktop component 1, a sub-desktop component 2, a left table leg 3 and a right table leg 4. The sub-desktop component 2 can be slidably installed on the main desktop component 1, the left table leg 3 is installed on the left side of the main desktop component 1, and the right table leg 4 is installed on the right side of the sub-desktop component 2.

[0026] The main table top assembly 1 includes a main table top 11, a main table frame 12 and a slide rail 13. The main table top 11 is installed on the upper part of the main table frame 12, and the slide rail 13 is installed on both sides of the lower part of the main table frame 12. A clamp 121 is provided at the right end of the main table frame 12. The left table leg 3 is installed on the left side of the main table frame 12.

[0027] The auxiliary table assembly 2 includes an auxiliary table plate 21, an auxiliary table frame 22, an inner frame 23 and an auxiliary rail 24. The auxiliary rail 24 is installed on both sides of the auxiliary table frame 22 and is slidably connected to the slide rail 13. The right table leg 4 is installed on the auxiliary rail 24, and the inner frame 23 is slidably installed on the auxiliary table frame 22. Figure 3 and Figure 7As shown, specifically, a U-shaped fixing member 221 is installed on the upper surface of the sub-desk frame 22, and the inner frame 23 is fixedly mounted on the sub-desk frame 22 via the U-shaped fixing member 221. A support tube 222 is provided inside the sub-desk frame 22 at a corresponding position on the inner frame 23. A stop tube 231 is provided on the left side of the inner frame 23, and a clamp 121 is provided on the right side of the stop tube 231 to limit the stop tube 231. The sub-desk board 21 is fixedly mounted on the sub-desk frame 22 in a manner that allows it to be raised and lowered. Specifically, the four corners of the sub-desk board 21 are fixedly connected to the sub-desk frame 22 via cylinders 211. A lifting assembly 5 is provided in the middle of the bottom of the sub-desk board 21. The lifting assembly 5 is movably connected to the inner frame 23. The support tube 222 limits the inner frame 23 to prevent it from shaking up and down during the extension process. When the right table leg 4 is extended, the sub-desk board 21 moves accordingly. The lifting assembly 5 allows the sub-desk board 21 to descend when retracted and ascend when extended. When retracted, the auxiliary table panel 21 is hidden under the main table panel 11 . When unfolded, the auxiliary table panel 21 is flush with the main table panel 11 .

[0028] like Figure 4 As shown, the lifting assembly 5 includes a slide member 51, a pin 52 and a guide bar 53. The slide member 51 is fixedly installed at the bottom of the auxiliary table board 21, and the pin 52 is fixedly installed on the outside of the inner frame 23 and cooperates with the slide member 51. The slide member 51 includes one or more slides 511. Preferably, there are two slides 511 on the left and right, which makes the connection more stable. The slide 511 includes a horizontal slide 5111 and an inclined slide 5112. The horizontal slide 5111 is set at the bottom of the slide member 51. One end of the inclined slide 5112 is connected to the middle of the horizontal slide 5111, and the other end extends upward and tilted to the upper end of the slide member 51. During the movement of the auxiliary table board 21, the pin 52 slides in the horizontal slide 5111. During the rising and falling of the auxiliary table board 21, the pin 52 slides in the inclined slide 5112 to realize the raising and lowering of the auxiliary table board 21. The guide bar 53 is rotatably connected to the connection between the horizontal chute 5111 and the inclined chute 5112, and can change direction under the action of the pin 52 to guide the movement direction of the pin 52. The guide bar 53 can rotate at an angle of 180 degrees.

[0029] In the folded state, the auxiliary table board 21 is below the main table board 11, and the pin 52 is at the uppermost end of the inclined slide groove 5112. Figure 5As shown, when unfolding, the right leg 4 is first pulled, driving the auxiliary panel 21, auxiliary frame 22, and inner frame 23 to move outward synchronously. When the latch 121 engages the stop tube 231, the inner frame 23 is restrained, and the pin 52 remains fixed. Continued movement of the right leg 4 then drives the auxiliary panel 21, auxiliary frame 22, and inner frame 23 to move synchronously. Driven by the auxiliary panel 21, the inclined slot 5112 moves upward, and the pin 52 gradually settles to the bottom of the inclined slot 5112, raising the auxiliary panel 21 to a position level with the main panel 11. Further pulling of the auxiliary panel 21 causes the horizontal slot 5111 to move outward, pushing the pin 52 open the guide bar 53. The guide bar 53 rotates upward and leftward along the connecting axis, and the pin 52 gradually settles to the leftmost end of the horizontal slot 5111. The guide bar 53 returns to its original position, returning the auxiliary panel 21 to its most extended position, creating a gap between the auxiliary panel 21 and the main panel 11. Then push the right table leg 4 inward, the horizontal slide groove 5111 moves to the left, the pin shaft 52 pushes open the guide bar 53, and the guide bar 53 rotates to the upper right along the connecting axis, blocking the entrance of the inclined slide groove 5112, preventing the pin shaft 52 from entering the inclined slide groove 5112, until the pin shaft 52 is at the rightmost end of the horizontal slide groove 5111, and the sub-table panel 21 is close to the main table panel 11.

[0030] like Figure 6 As shown, when shrinking, the sub-table plate 21 can be retracted by following the reverse process of expanding.
