Description

A table leg folding structure

technical field

The utility model relates to a table, in particular to a table leg folding structure.

Background technique

Folding tables in the prior art are usually pivotally connected with a set of interlocking cross table legs on both sides of the bottom of a table board. On the table legs, when you want to fold it up, you can bend one of the crossed table legs so that the two table legs are close together, and turn up the table board, so that the folding table can be folded and erected. However, after such a folding table is folded, the table legs usually protrude from the table board, that is, the length of the table legs should be greater than the width of the table board, so as to ensure the proportion of the table, but the folded volume is too large. Not good for carrying. If the length of the table legs is less than the table board, the height of the normal table cannot be reached after the table is unfolded.

Fig. 1 is another type of folding table in the prior art, including desktop board 1 ' and table frame 2 ', and table frame 2 ' comprises two beams 21 ', three longitudinal beams 22 ', two groups of table legs 23 ' and two Support rod 24', wherein the beam 21' is fixed on the back of the desktop, the longitudinal beam 22' is pivotally connected to the two ends and the middle of the two beams 21', and the two sets of table legs are respectively fixed on the longitudinal beam 22' at both ends, and the supporting rod It is "Y"-shaped, one end of which is fixed on the table leg 23', and the other end is pivotally connected to the longitudinal beam in the middle of the beam 21'. When you want to carry or store the table, turn the back of the table top 1' upward and pull the table downward. The legs 23' exert force, and the table legs 23' are received against the back of the desktop 1', reducing the volume. But this table frame structure is still comparatively complicated, and it is not convenient to use.

Utility model content

The purpose of the utility model is to provide a table leg folding structure, which is convenient and quick to fold, and has a simple structure.

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

A table leg folding structure, comprising two crossbars fixed on the bottom surface of the table board and two sets of brackets movably connected to the near ends of the two crossbars, each bracket respectively includes a longitudinal bar with two ends pivoted on the two crossbars and For the two table legs connected to the vertical bar, a support rod is provided between each table leg and the adjacent cross bar. There is a positioning locking device that is locked with the cross bar when the table is unfolded.

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

Further, the upper end of the support rod is pivotally connected to a sliding sleeve, and the positioning and locking device is arranged in the sliding sleeve, and the cross bar is provided with a positioning hole matched with the locking device.

After adopting the above structure, through the movement of the sliding sleeve at the upper end of the support rod on the cross bar, the support rod supports the table leg, thereby driving the table leg to stand upright, and has the positioning function of the positioning locking device. When the sliding sleeve is disengaged from the locking After the device slides in the opposite direction, the table legs move down with the support rods to fit the bottom of the table, even if the table legs are folded. The utility model is simple in structure, does not affect the volume of the table after the table legs are folded, and the operation is convenient and quick.

Detailed ways

In order to further explain the technical solution of the utility model, the utility model is described in detail through specific examples below.

What the utility model discloses is a kind of folding table leg structure, as shown in Fig. 2, 3, 4, the table 10 includes a table board 1, and the table board 1 is provided with two crossbars 11 and the near ends of the two crossbars. The two groups of supports 2 that are movably connected, each support 2 includes a longitudinal bar 22 pivotally connected to two cross bars 11 at both ends and two table legs 21 connected to the longitudinal bars 22, one of the two table legs 21 of the same support 2 A reinforcing rod 23 is also arranged horizontally between them.

The key points of the design of the present utility model are: a support rod 3 is arranged between each table leg 21 and the adjacent cross bar 11, the lower end of the support rod 3 is pivotally connected to the table leg 21, the upper end is pivotally connected to a sliding sleeve 4, and the sliding The sleeve 4 is sleeved on the cross bar 11, and a positioning and locking device 41 is provided in the sliding sleeve 4, and a positioning hole 42 cooperating with the locking device 41 is provided on the cross bar 11, and the sliding sleeve 4 passes through the positioning and locking device 41 and The corresponding positioning hole 42 is positioned after sliding on the cross bar 11 .

When the table 10 is to be stood on the ground, that is, the table legs are upright and in an open state, after the table 10 can be turned upside down, each sliding sleeve 4 is slid towards the two ends of the cross bar 11 to reach the predetermined positioning hole 42, and the sliding sleeve The positioning and locking device 41 in 4 is fixed in the positioning hole 42 of the cross bar 11, and the support rod 3 is driven by the sliding sleeve 4 to support the table leg 21, so that the table leg 21 rises and finally stands upright. , A fixed state of support and connection is formed between the cross bar 11 and the table legs 21, and the two sets of brackets 2 can be opened to make the table stand on the ground. When the table needs to be folded up, as shown in Fig. 3 and Fig. 4, push the positioning locking device 41 of the sliding sleeve 4 to break away from the positioning of the positioning hole 42, and as the sliding sleeve 4 slides to the middle of the cross bar 11, the supporting rod 3 Also slide down until the support bar 3 moves down to be parallel to the cross bar 11, the table legs 21 can also be attached to the bottom surface of the table, and the support 2 completes the process from standing upright to folding. positioning hole. It can be seen that, to fold or stand the table legs, it is only necessary to push the sliding sleeve 4, the support 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 hole can be realized. . The folding structure of the table legs provided by the utility model has a simple structure, does not affect the volume of the table after being folded, and is convenient and quick to operate.

The above-mentioned embodiments and drawings do not limit the product form and style of the present utility model, and any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of the present utility model.
