Description

Folding mechanism and folding table

technical field

The utility model relates to a folding mechanism, and the utility model also relates to a table using the mechanism.

Background technique

The folding mechanism of the current folding table is relatively complicated, including many parts, and the assembly is more troublesome, and the folding and storage are also more troublesome and laborious. The user needs to hit the folding rod hard to bend the two straight folding rods fixed together to complete the folding work. , In addition, after folding, all the folding parts are not accommodated in one part, thus occupying a relatively large usable area.

Utility model content

The purpose of the utility model is to provide a folding mechanism to solve the technical problem of how to make the structure of the folding mechanism simple, and all the parts can be accommodated inside one part after folding, so as to reduce the occupied area.

Another object of the utility model is to provide a folding table using the mechanism.

A folding mechanism comprising at least 2 folding assemblies, each folding assembly comprising a fixed bar, a support bar that fits within the fixed bar when folded, an upper miter hinged to the fixed bar and placed within the fixed bar and the support bar when folded A rod, a lower miter rod that is hinged to the support rod and fits within the upper miter rod when folded, wherein the upper miter rod and the lower miter rod are hingedly connected to each other.

The upper miter rod is hingedly connected to the fixed rod at 45 degrees.

The lower miter rod is hingedly connected with the support rod at 45 degrees.

The fixed rods, support rods, upper miter rods, and lower miter rods are all groove-shaped, and their inner widths are correspondingly reduced in sequence.

A connecting piece is connected between the fixing rod and the supporting rod, the fixing rod is hinged on one side of the connecting piece, and the supporting rod is hinged on the bottom of the connecting piece.

A movable handle for folding the upper miter rod into the interior of the fixed rod is connected between the fixed rod and the upper miter rod.

Folding table, comprising tabletop, folding mechanism; folding mechanism, comprising at least 2 folding assemblies, each folding assembly comprising a fixed rod, a support rod which fits inside the fixed rod when folded, hinged to the fixed rod and puts in when folded The upper miter rod in the fixed rod and the support rod, the lower miter rod hinged with the support rod and put into the upper miter rod when folded, wherein the upper miter rod and the lower miter rod are hingedly connected to each other.

The upper miter rod is hingedly connected to the fixed rod at 45 degrees, and the lower miter rod is hinged to the support rod at 45 degrees.

The fixed rods, support rods, upper miter rods, and lower miter rods are all groove-shaped, and their inner widths are correspondingly reduced in sequence.

A connecting piece is connected between the fixing rod and the supporting rod, the fixing rod is hinged on one side of the connecting piece, and the supporting rod is hinged on the bottom of the connecting piece.

The beneficial effect of the utility model is: the folding mechanism mainly only includes four parts of the fixed rod, the support rod, the upper miter rod, and the lower miter rod. Moreover, when the upper miter rod is folded into the fixed rod by shaking the hand, the lower miter rod and the support rod can be folded into the fixed rod at the same time, so that all parts of the folding mechanism can only be accommodated in one part after folding, occupying an area Greatly reduced and also convenient for transportation.

Detailed ways

Please refer to FIG. 1 to FIG. 2 , the folding mechanism 1 in the figure includes two symmetrically arranged folding assemblies 2 , each folding assembly 2 includes a fixed rod 21 , and a support that can be put into the fixed rod 21 when folding. Rod 22, one is hinged with fixed rod 21 and puts into the upper miter rod 23 in fixed rod 21 and support rod 22 when folding, one is hinged with support rod 22 and puts in the lower miter rod 23 when folded. The miter rod 24, wherein the upper miter rod 23 and the lower miter rod 24 are hingedly connected to each other. In order to make the upper miter rod 23 and the lower miter rod 24 evenly and conveniently folded, the hinge angle between the upper miter rod 23 and the fixed rod 21 is 45 degrees during installation. Similarly, the lower miter rod 24 and the support rod 22 also has an articulation angle of 45 degrees. In order to fold the supporting rod 22, the upper miter rod 23 and the lower miter rod 24 into the fixed rod 21 when folding, the fixed rod 21, the support rod 22, the upper miter rod 23 and the lower miter rod 24 They are all made into a groove shape, which can also be called U-shaped, and the inner width 28 is correspondingly reduced in turn, so that the support rod 22 can be put into the fixed rod 21, and the upper miter rod 23 can be put into the inside of the support rod 22 , The lower miter rod 24 can be put into the upper miter rod 23 inside, and the so-called inner width 28 refers to the width of the groove-shaped inner surface bottom. Can be directly hinged between fixed rod 21 and support rod 22, also can connect a connecting piece 25 between the two to facilitate installation, after increasing connecting piece 25, fixing rod 21 is just hinged on the left side of connecting piece 25, and supporting rod 22 Then it is hinged at the bottom of the connector 25 . For the convenience of folding and unfolding, an inwardly arranged Z-shaped movable handle 26 can be added between the fixed rod 21 and the upper miter rod 23 . The handle 26 realizes the folding action when shaking outwards, and realizes the unfolding action when shaking inwards. Above-mentioned hinged connection refers to be connected together by bolt 27 hinged.

In practical applications, there may be multiple folding components 2, such as 3 or 4, and the folding components 2 may not be arranged symmetrically.

Please refer to FIG. 3 , the folding table in the figure includes a desktop board 3 and a folding mechanism 1 ; the desktop board 3 is a common panel, and the folding mechanism 1 is the folding mechanism described above.
