Abstract

A table legs folding structure is provided. The table legs folding structure comprises two cross rods (11) fixed on the underside of a table plate (1) and two sets of holder (2) movably connected with the two cross rods (11) near the ends of the two cross rods (11). Each set of holder (2) comprises a longitudinal rod (22) with two ends pivoted to the two cross rods(11) and two table legs (21) connected to the longitudinal rod (22). A stiffening rod (23) is transversally disposed between the two table legs (21) of the same holder (2). A supporting rod (3) is disposed between each table leg (21) and its adjacent cross rod (11). The upper end of the supporting rod (3) is pivotally connected to the cross rod (11), and the lower end of the supporting rod (3) is slidely disposed on the table leg (21). A position locking device (41) is disposed on the lower end of the supporting rod (3). The position locking device (41) will lock the table leg (21) when the table is open. A sliding sleeve (4) on the lower end of the supporting rod (3) moves along the table leg (21), so that the supporting rod (3) supports the table leg (21), thus the table leg (21) is upright. And then the sliding sleeve (4) is positioned by the position locking device (41). When the sliding sleeve (4) separates from the position locking device (41) and then slides away from it, the table leg (21) moves with the supporting rod (3) to get close to the underside of the table, thus the table leg (21) is folded. The table legs folding structure does not affect the size of the table when the table legs are folded. It has a simple structure and is easy to operate.

Description

Table foot folding structure

技术领域Technical field

The present invention relates to a table, and more particularly to a table leg folding structure.

背景技术Background technique

The folding table in the prior art generally pivots a set of cross-table legs that can be interlocked with each other on the lower sides of a table. When the rack is to be deployed, the cross-legs are spent, and the table is supported by the cross. On the table legs, when you want to put them away, bend the legs of the cross table legs, make the two table legs close together, and flip the table board to fold the folding table up. However, after the folding table is folded, the table legs usually extend out of the table, that is, the length of the table legs is greater than the width of the table, so as to ensure the proportion of the table, but the folding volume is too large. Not conducive to carrying. If the length of the table legs is less than the table top, the table will not reach the height of the normal table.

1 is another type of folding table in the prior art, including a table top 1' and a table stand 2'. The table stand 2' includes two beams 21', three longitudinal beams 22', two sets of legs 23' and two Supporting rod 24', wherein the beam 21' is fixed to the back of the table top, the longitudinal beam 22' is pivotally connected to the two ends and the middle of the two beams 21', and the two sets of legs are respectively fixed on the longitudinal beams 22' of the two ends, the support rod It is 'Y' type, one end is fixed on the table leg 23', and the other end is pivotally connected to the longitudinal beam of the middle part of the beam 21'. When carrying or collecting the table, the table 1' is back up and the table is pulled down. The leg 23' exerts a force, and the leg 23' is placed against the back of the table 1' to reduce the volume. However, the structure of the table is still relatively complicated and is not convenient to use.

发明内容Summary of the invention

The object of the present invention is to provide a table foot folding structure, which is convenient and quick to fold and fold, and has a simple structure.

In order to achieve the above object, the solution of the present invention is:

The table leg folding structure comprises two cross bars fixed on the bottom surface of the table board and two sets of brackets movably connected with the proximal ends of the two cross bars, each bracket respectively comprising a longitudinal rod pivotally disposed on the two cross bars and a pair of legs connected to the longitudinal rod, a support rod is arranged between each of the legs and the adjacent crossbar, the upper end of the support rod is pivotally connected to the crossbar, and the lower end is slidably disposed on the table leg, and the lower end of the support rod is disposed A positioning locking device that locks with the table legs when the table is unfolded.

Further, a reinforcing rod is horizontally disposed between the two legs of the same bracket.

Further, the lower end of the support rod is pivotally connected to a sliding sleeve, and the positioning locking device is disposed in the sliding sleeve, and the positioning leg is matched with the locking device.

After adopting the above structure, the support rod supports the table legs through the movement of the sliding sleeve at the lower end of the support rod, thereby supporting the table legs to stand upright, and positioning the locking device to disengage the sliding sleeve. After the device slides in the opposite direction, the table legs move down with the support bar to the bottom of the fitting table, even if the table legs are folded.

The invention has simple structure, does not affect the volume of the table after the table legs are folded, and is convenient and quick to operate.

具体实施方式detailed description

In order to further explain the technical solutions of the present invention, the present invention will be described in detail below by way of specific embodiments.

The invention discloses a table leg folding structure. As shown in FIGS. 2, 3 and 4, the table 10 comprises a table board 1 , and two cross bars 11 are arranged under the table board 1 and the proximal ends of the two cross bars are movable. Two sets of brackets 2 are connected, each bracket 2 includes a longitudinal rod 22 pivotally connected to the two crossbars 11 and two legs 21 connected to the longitudinal rod 22, and the upper and middle portions of the two legs 21 of the same bracket 2 A reinforcing rod 23 is also disposed between the two.

The design point of the present invention is that a support rod 3 is disposed between each leg 21 and the adjacent crossbar 11. The upper end of the support rod 3 is pivotally connected to the crossbar 11, and the lower end is pivotally connected to a sliding sleeve 4, and the sliding sleeve 4 is The sleeve 4 is disposed on the table leg 21, and a positioning locking device 41 is disposed in the sliding sleeve 4. The table leg 21 is provided with a positioning hole 42 for engaging with the locking device 41. The sliding sleeve 4 is positioned and locked by the positioning device 41 and correspondingly positioned. The hole 42 is positioned after sliding on the table leg 21.

When the table 10 is to be placed on the ground, that is, the legs are respectively erected and opened, the table 10 can be inverted, and the sliding sleeve 4 is pushed along the table legs 21 toward the bottom of the table to the positioning hole 42, the sliding sleeve 4 The positioning fixing device 41 is locked in the positioning hole 42 of the cross bar 11, and the support rod 3 is driven by the sliding action of the sliding sleeve 4, thereby supporting the table leg 21, raising the table leg 21 and finally standing upright. At the same time, a fixed state of support connection is formed between the crossbar 11 and the table leg 21, and both sets of brackets 2 can be opened to stand the table on the ground. When the table 10 is to be folded up, as shown in FIG. 3 and FIG. 4, the sliding sleeve 4 is pushed, the positioning locking device 41 is disengaged from the positioning hole 42, and the sliding sleeve 4 is slid toward the standing ground end of the table leg until The support rod 3 drives the table legs 21 to move to the bottom surface of the table until it fits on the bottom surface of the table, and the bracket 2 completes the process of standing up to the folding. At this time, a positioning hole can be further disposed on the table legs 21. It can be seen that, in order to fold or erect the table legs, it is only necessary to push the sliding sleeve 4, the supporting rod 3 drives the unfolding and folding of the table legs 21, and the positioning function of the positioning locking device 41 and the positioning holes can be realized. .

The table leg folding structure provided by the invention has a simple structure, does not affect the volume of the table after folding, and is convenient and quick to operate.

The above-mentioned embodiments and the drawings are not intended to limit the scope of the invention, and any suitable variations or modifications of the invention will be apparent to those skilled in the art.
