Description

Technical Field

[0001] This utility model relates to the field of folding tabletop connection technology, and in particular to a folding tabletop telescopic lifting mechanism. Background Technology

[0002] To maximize space utilization, existing tabletops, cabinet shelves, countertops, and kitchen counters are equipped with folding countertops. When in use, the folding countertop is pulled out and raised to be flush with the tabletop, cabinet shelf, countertop, or kitchen counter, expanding the usable area. When not in use, the folding countertop is lowered and retracted under the tabletop, cabinet shelf, countertop, or kitchen counter. The telescopic lifting mechanism of the existing folding countertop is directly fixed to the two side panels under the tabletop, cabinet shelf, countertop, or kitchen counter by drilling mounting holes on the outermost slide rail. When installing the folding countertop, first, according to the size of the slide rail mounting holes, measure and mark the positions of the fixing holes on the two side panels under the tabletop, cabinet shelf, countertop, or kitchen counter. Next, drill the fixing holes on the side panels according to the marked fixing hole positions. Then, move out the outermost slide rail, align the mounting holes of the outermost slide rail with the fixing holes on the side panels, and finally fix it with screws. However, due to the limited space under tabletops, cabinets, countertops, or kitchen counters, measuring and drilling the side panels below is difficult and requires high precision. Combined with measurement and drilling errors, the accumulated hole deviations are significant, making it hard to align the mounting holes on the slide rails with the fixing holes on the side panels. Furthermore, the need to remove the outermost slide rail during screw fixing causes a shift in the center of gravity of the telescopic lifting mechanism, resulting in the outermost slide rail lifting up. This necessitates constant pressure on the removed outermost slide rail during installation. Therefore, the existing installation and fixing procedures for folding tabletop telescopic lifting mechanisms are numerous, prone to misalignment, and require repairs or even re-drilling, resulting in time-consuming installations and inconsistent installation quality. Utility Model Content

[0003] The purpose of this invention is to provide a method for quickly installing a folding tabletop telescopic lifting mechanism without requiring measurements, drilling holes in the side panels, or removing the outermost slide rail. This method offers convenient installation and high-quality installation, thus solving the problems mentioned in the background section.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A folding tabletop telescopic lifting mechanism includes a pair of opposing fixed seats, a slide rail assembly connected to the inner sides of the two fixed seats and slidable along the length of the fixed seats, a folding tabletop mounting plate rotatably pivotally connected to the inner side of the slide rail assembly, and a balance bar connected between the slide rail assemblies. Each fixed seat includes a fixed side plate, a slide platform provided on the fixed side plate along its entire length, and fixed holes formed on the fixed side plates on both sides of the slide platform. The upper and lower end faces of the fixed side plates serve as mounting and positioning surfaces. Each slide rail assembly includes at least one slide rail, which is slidably fitted onto the slide platform. A first pivot member and a second pivot member are pivotally connected to both ends of the slide rail on the side facing away from the slide platform. The folding tabletop mounting plate has downward-facing lugs on one side near both ends, and the folding tabletop mounting plate is fixed to the outer ends of the first and second pivot members via the two lugs.

[0006] Furthermore, a positioning code is detachably installed on the same side end of the pair of fixed seats. The positioning code includes a positioning code body and a positioning block vertically disposed at one end of the positioning code body. It is detachably installed on the end of the fixed seat through the other end of the positioning code body.

[0007] Preferably, the other end of the positioning code body is provided with an insertion strip, and the slide end of the pair of fixed seats on the same side is provided with an insertion groove. The positioning code is inserted into the insertion strip groove through the insertion strip and is detachably connected to the end of the fixed seat.

[0008] More preferably, the insertion slots of the slides of the pair of fixed seats extend through the entire length of the slide.

[0009] More preferably, the slide with a through insertion slot along its entire length is provided with support platforms at intervals.

[0010] Furthermore, the slide rail assembly includes a first slide rail and a second slide rail. One side of the first slide rail is fitted onto the slide table, and one side of the second slide rail is fitted onto the other side of the first slide rail. A first pivot member and a second pivot member are respectively pivotally connected to the other side of the second slide rail near both ends.

[0011] Preferably, the first or second slide rail is provided with a support column.

[0012] Furthermore, a buffer assembly is provided between the slide rail assembly and the folding table mounting plate. The buffer assembly includes a damper and a spring. One end of the damper is connected to the pivot assembly of the first pivot member, and the other end of the damper is fixed to the side of the slide rail assembly away from the slide table. One end of the spring is connected to the end of the folding table mounting plate near the first pivot member, and the other end of the spring is connected to the pivot assembly of the second pivot member.

[0013] The beneficial effects of this utility model are as follows: When installing the folding tabletop telescopic lifting mechanism, it is only necessary to attach the fixing side plates of a pair of fixing seats to the lower side plate or wall near the top of the tabletop, cabinet, counter, or kitchen counter, and align the upper end of the fixing side plates with the bottom surface of the tabletop, cabinet, counter, or kitchen counter. Then, an electric screwdriver can be used to install the folding tabletop telescopic lifting mechanism on the side plates by aligning the screws with the fixing holes on both sides of the slide. There is no need to measure, drill holes on the side plates, or move the outermost slide rail. The installation is convenient and the installation quality is high. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be further described clearly and completely below in conjunction with the embodiments of this utility model. It should be noted that the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] Example 1

[0025] like Figures 1-2 As shown, the present invention provides a folding tabletop telescopic lifting mechanism, which includes a pair of fixed seats 1 facing each other, a slide rail assembly 2 connected to the inner sides of the two fixed seats and slidable along the length of the fixed seats, a folding tabletop mounting plate 3 rotatably pivotally connected to the inner side of the slide rail assembly, and a balance bar 4 connected between the slide rail assemblies.

[0026] Among them, such as Figure 1 As shown, the fixing base 1 includes a fixing side plate 11, a slide table 14 arranged along the entire length of the fixing side plate, and fixing holes 13 formed on the fixing side plates on both sides of the slide table. The upper and lower end faces 12 of the fixing side plate 11 serve as mounting and positioning surfaces. The slide rail assembly 2 includes at least one slide rail. In the accompanying drawings of this embodiment, the slide rail assembly includes a first slide rail 21 and a second slide rail 22. One side of the first slide rail 21 is fitted onto the slide table 14, and one side of the second slide rail 22 is fitted onto the other side of the first slide rail 21. The first slide rail 21 is slidable relative to the slide table, and the second slide rail 22 is slidable relative to the first slide rail 21. Figure 3 As shown, on the other side of the second slide rail 22, near both ends, a first pivot member 5 and a second pivot member 6 are respectively pivotally connected by a pivot assembly 7. The pivot assembly 7 includes a support sleeve 72 and a bolt 71. The first pivot member 5 and the second pivot member 6 are rotatably pivotally connected to the side of the second slide rail through the pivot assembly 7. The folding tabletop mounting plate 3 includes a folding tabletop support plate surface 31 and lugs 32 that are downwardly arranged on one side near both ends. The folding tabletop mounting plate 3 is fixed to the outer ends of the first pivot member 5 and the second pivot member 6 by the two lugs 32 and screws 33.

[0027] like Figure 1 and Figure 3 As shown, the balance bar 4 has fitting holes 41 at both ends, and the first pivot member 5 has a fitting post 51 at the other end. The balance bar 4 is fitted onto the fitting posts of the first pivot member 5 on both sides through the fitting holes 41 at both ends, so as to achieve balance between the fixed base, slide rail assembly and folding table mounting plate on both sides.

[0028] When selling this utility model of a folding tabletop telescopic lifting mechanism, except for the balance bar which is not installed, one of the two fixed seats has already been installed together with the slide rail assembly and the folding tabletop mounting plate, forming two sets of components on the left and right sides. Then, use an electric screwdriver to install the assembled components onto the side panel or wall with screws aligned with the fixing holes. Next, attach one end of the balance bar to the first pivot member 5 that has been installed and fixed, and attach the other end of the balance bar to the assembled components that have not yet been installed on the side or wall. Then, attach the other fixed seat, slide rail assembly, and folding tabletop mounting plate to the side panel or wall B on the side below the tabletop, cabinet, counter, or kitchen counter, close to the top, while aligning the upper surface of the fixed side panel with the bottom surface of the tabletop, cabinet, counter, or kitchen counter. Use an electric screwdriver to install the assembled components onto the side panel or wall with screws aligned with the fixing holes. This completes the installation of the folding tabletop telescopic lifting mechanism. Finally, place the folding tabletop A on the folding tabletop mounting plates on both sides and fix it. The installed state is as follows. Figure 5 As shown.

[0029] When installing the folding tabletop telescopic lifting mechanism of this utility model, simply attach the fixing side plates of a pair of fixing seats to the lower side plate or wall near the top of the tabletop, cabinet, counter, or kitchen counter, and align the upper surface of the fixing side plates with the bottom surface of the tabletop, cabinet, counter, or kitchen counter. Then, use an electric screwdriver to install the folding tabletop telescopic lifting mechanism on the side plates by aligning the screws with the fixing holes on both sides of the slide. There is no need to measure, drill holes in the side plates, or remove the outermost slide rail. The installation is convenient and of high quality.

[0030] Preferably, such as Figure 4 As shown, a buffer assembly consisting of a damper 9 and a spring 8 is also provided between the slide rail assembly 2 and the folding table mounting plate 3. One end of the damper 9 is connected to the pivot assembly 7 of the first pivot member 5, and the other end of the damper 9 is fixed to the side of the slide rail assembly 2 away from the slide table. One end of the spring 8 is connected to the hook at the end of the folding table mounting plate 3 near the first pivot member 5, and the other end of the spring 8 is connected to the pivot assembly 7 of the second pivot member 6. This ensures good buffering force when the folding table moves up and down, making the folding table up and down movement mechanism have a longer service life.

[0031] Preferably, such as Figure 1 As shown, the first or second slide rail is equipped with a support column 23. This enhances the overall strength of the slide rail and prevents deformation due to its long length during use from affecting the sliding motion of the slide rail.

[0032] Example 2

[0033] like Figure 6-8The image shows another embodiment of the folding tabletop telescopic lifting mechanism of this utility model. This embodiment is based on embodiment 1, with a positioning code 10 detachably installed at the end of a pair of fixed seats on the same side (near the side panel or the outside of the wall). The positioning code 10 includes a positioning code body 101 and a positioning block 102 vertically disposed at one end of the positioning code body. The positioning code body is detachably installed at the end of the fixed seat through the other end. In this embodiment of the utility model, the other end of the positioning code body is provided with an insertion strip 103. An insertion groove 16 is opened at the end of the slide on the same side of the pair of fixed seats. The positioning code is inserted into the insertion strip groove through the insertion strip and is detachably connected to the end of the fixed seat. Of course, it can also be fixed to the end of the fixed seat by screws.

[0034] In the case of the folding tabletop telescopic lifting mechanism, the positioning code 10 is already assembled on the fixed base when it is sold. During installation, compared to Example 1, first, one of the fixed bases, the positioning code, the slide rail assembly, and the folding tabletop mounting plate are assembled and fixed to the front side of the side panel or wall B using the positioning block of the positioning code. Next, while fixing the side panel to the side panel or wall B on the side below the tabletop, cabinet, counter, or kitchen counter, the upper end of the fixed side panel is aligned with the bottom surface of the tabletop, cabinet, counter, or kitchen counter. The installation state is as follows. Figure 8 As shown, it achieves three-axis positioning similar to the XYZ axes (front, back, and top), enabling faster and more precise installation of the mounting bracket assembly. After installation and folding the tabletop, the positioning codes can be removed.

[0035] Preferably, such as Figure 7 As shown, the insertion slots of the slides of a pair of fixed seats extend through the entire length of the slides, which facilitates molding and processing.

[0036] Preferably, such as Figure 2 As shown, the slide table 14 is provided with support platforms 15 at intervals along its length. The support platforms can enhance the overall strength of the fixed seat and prevent the slide rail from being affected by deformation during use due to the long length of the fixed seat.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
