Lifting and dropping linkage device for tea table or dining table

Abstract

The invention discloses a lifting and dropping linkage device for a tea table or a dining table. The lifting and dropping linkage device comprises a table board and table legs connected with the table board, and is characterized in that each table leg is divided into two sections, the upper section is fixedly connected with the table board, and the lower section is set as a foot section; a connecting rod hinged to each upper section and the corresponding lower section is arranged between the upper section and the lower section and arranged on one side of the table board, the dislocated lifting and dropping height between the upper section and the lower section is determined by the hinge distance of the connecting rod, the upper section is located on the end surface of the lower section through the connecting rod after lifted, and the upper section is folded in a dislocated manner with the lower section after dropped; and a connecting plate is arranged between each upper section and the corresponding lower section and arranged on the other side of the table board, one end of the connecting plate is hinged to the upper section, the other end is hinged to the lower section, the dislocated lifting and dropping height between the upper section and the lower section is determined by the hinge distance of the connecting plate, the upper section is supported by the connecting plate after lifted and positioned through arranged lockhole bolts, and the upper section is also folded in a dislocated manner with the lower section after dropped. Compared with the prior art, the lifting and dropping linkage device for the tea table or the dining table has the advantages of simple structure, low manufacture cost, convenience in operation and use, firmness, steadiness, attractiveness and the like.

Description

technical field : [0001] The invention relates to a lifting linkage device for a coffee table or a dining table, in particular to a lifting linkage device for a coffee table. Background technique : [0002] At present, the coffee table of the prior art is generally all inconvenient to be used as a dining table because of its low height, and the dining table is inconvenient to be used as a coffee table because of its high height. Therefore, a lifting linkage device for a tea table is provided, especially the tea table, which can be raised to be used as a dining table when necessary, and then lowered back to the tea table after use, which will bring great convenience to the daily life of the family. However, the lifting devices in the prior art generally have complicated structures and high costs, and are especially inconvenient to operate during use. For example: in the Chinese patent authorization announcement number CN201691332U, a lifting auxiliary device for lifting co...
