Folding table

Technical Field

The utility model relates to a table field, concretely relates to folding table.

Background

The structure of folding table has the multiple, and one of them is the relative rotatable structure of table frame of stand, and the stand can be folded on table frame when not using, then expandes the stand to be the vertical state with table frame and thereby support table frame when needing to use, locks through locking structure under the state of expandeing.

For example, chinese patent No. CN207940474U, the patent name "electric lifting table" discloses a similar folding table structure, which comprises a table top, a cross bar frame connected to the bottom surface of the table top, a lifting column connected to the cross bar frame, and a table foot connected to the end of the lifting column; the upper end of the lifting column is hinged with the cross rod frame and is locked by a locking structure when the lifting column and the cross rod frame are in a vertical opening state; this locking structure is including connecting screens piece, the screens slider on the horizontal pole frame of sliding connection on the lift post and being used for the elastic component with screens piece chucking on the screens slider, and elastic component connects on the horizontal pole frame.

However, the folding table has some problems that the upright post is locked with the table frame in a rotating motion state when being unfolded, and if the locking structure has manufacturing or installation errors, the upright post and the table frame are difficult to maintain in a locking state, and the stability of the folding table is affected.

SUMMERY OF THE UTILITY MODEL

Manufacturing or installation error to locking structure in current folding table can lead to the stand to be difficult to and table frame keep the lock-out state, influences the not enough of folding table stability, the utility model aims to provide a folding table carries out improved design to the locking structure between stand and the table frame for can stabilize the locking with table frame when the stand expandes, can effectively eliminate simultaneously and make installation error, improve whole table stability.

In order to achieve the above purpose, the utility model provides a following technical scheme: folding table, including table frame and stand, the tip of stand articulates on table frame through the hinge, be equipped with locking structure between stand and the table frame, locking structure includes jack catch and joint spare, and the jack catch rotates through the pivot and sets up on one in table frame or stand, and the joint spare is fixed on another in table frame or stand, and joint spare card is in the jack catch after the stand expandes.

Among this technical scheme, when the stand need expand, the stand is outwards rotatory, and after joint spare and jack catch contact, joint spare can drive the jack catch and outwards rotate, and after the jack catch rotated certain angle, joint spare can block into the jack catch in, can fix fast after the stand is rotatory, accomplishes the installation of folding table. When the stand needs be folded, only need manpower or use tool with the outside enough angle of rotation of jack catch for the joint spare can follow the jack catch in the roll-off, again with the stand internal rotation to with the laminating of table frame, accomplish the folding of folding table. In-process that expandes at the stand, the action of joint spare, jack catch is rotary motion together, does not relate to the conversion of motion type (for example the slip of the rotatory screens slider that turns into of joint spare among the prior art), and low to the requirement of assembly precision, can effectively eliminate and make installation error, stability when improving folding table and expandes, locking structural component is few, and simple structure has practiced thrift packaging cost, and the later stage is dismantled the shipment convenience.
