Hidden lifting tea table

Abstract

The invention relates to a hidden lifting tea table. The hidden lifting tea table comprises a table body, a tea table top, two overturning cover plates and a lifting motor, the inner end of a second connecting rod is rotationally connected with the upper end of a third connecting rod, the second connecting rod is equipped with an inner limiting plate on the inner side of a first connecting rod, and an inner tension spring is arranged between the first connecting rod and the second connecting rod or an outer limiting plate is arranged on the outer side of the first connecting rod at the outer end of the second connecting rod. Due to the rotating connection and stress relation of the first connecting rod and the second connecting rod, the two overturning cover plates can only move upwards after being touched, so that when the two overturning cover plates are folded, the two overturning cover plates are overturned inwards in the lower direction of the opening of the table body firstly, then move upwards after being folded and finally move to the opening of the table body; thus, interference of a table board is completely avoided, the hidden lifting tea table can be matched with two overturning cover plates of any thickness, it can be guaranteed that the gap between the overturning cover plates and the edge of the opening of the table body is smaller than 3mm, and the hidden lifting tea table is convenient and flexible to produce.

Description

technical field [0001] The invention relates to the technical field of coffee tables, in particular to a hidden liftable coffee table. Background technique [0002] At present, the existing hidden lifting coffee table is a lifting coffee table with hidden function announced in Chinese Patent No. 201921032412.8 on April 24, 2020. This coffee table can lower the top plate of the coffee table when not drinking tea. Into the inner cavity of the coffee table, after the motor drives the top plate of the coffee table down for a certain height, the top plate of the coffee table presses the limit rod and moves downward, and the limit rod drives the two first racks to move downward at the same time, so that the two pinches are separated from each other. Rotating under the action of the tooth grooves of the two first racks, the two pinches drive the two table bodies to flip upwards in opposite directions at the same time, finally making the two table bodies move from the vertical state...

AI Technical Summary

Problems solved by technology

In order to prevent the two overturning cover plates from interfering with the table when they are turned over, the manufacturer of the lifting coffee table needs to make the edge of the opening of the inner cavity of the coffee table very thin (that is, reduce the thickness of the table at the opening), which eventually leads to the opening of the inner cavity of the coffee table. The edge strength is not enough, and it is easy to be deformed by pressure; or, the manufacturer of the hidden lift coffee table design has a large gap between the outer edge of the flip cover and the edge of the opening of the inner cavity. After the two flip covers are completely closed, the flip cover The gap between the outer edge of the coffee table and the opening edge of the inner cavity is very large, resulting in an unsightly surface after the coffee table is converted into an ordinary table

The above-mentioned gap is approximately equal to the thickness of the table at the opening. At present, there are hidden lift coffee tables on the market. The table is generally made of a thin plate with a thickness of ≤3mm around the opening, such as a steel plate, and then generally on the upper surface of the steel plate. Paste wood grain paper to make the appearance of the upper surface of the desktop consistent with the wooden coffee table as a whole, because wood boards with a thickness of ≤3mm are not only inconvenient to produce, but also have insufficient strength

At present, the table boards of hidden lift coffee tables on the market can also be directly made of wood. For wood boards, manufacturers of hidden lift coffee tables adopt the method of reducing the thickness of the table board at the opening, but the thickness of the wood board is generally greater than 3mm. At this time, it is necessary to chamfer the inner cavity of the table board. The minimum gap between the flip cover and the inner cavity of the table board is approximately equal to the thickness of the thinnest part of the chamfered position of the inner cavity. In order to make the minimum gap as small as possible, the thickness is It needs to be as small as possible. When the thickness is ≤3mm, the strength of the table at this thickness will be severely weakened, and there will inevitably be a natural contradiction that the minimum gap is as small as possible and the strength of the table is not severely weakened.

(2) At present, the lifting coffee table on the market that uses the screw rod and the screw nut block to realize the turning of the flip cover has high requirements on the precision of the motor. If the screw nut block is not lowered in place, the two flip cover plates will not close together. , there is an obvious gap between the two flip covers, and the two flip covers are not flipped up in place, and the top surfaces of the two flip covers are not flush with the table top, which eventually leads to an unsightly appearance of the table top

If the screw nut block is lowered too much, it will cause the two overturned cover plates to squeeze each other, the motor will be in an overloaded working state, and the motor will also be overheated or even burnt out due to stalling, and the service life will be shortened

(3) In addition, the two flip covers of the concealed lift coffee table currently on the market are closed towards each other under the drive of the motor, and the two flip covers are clamped towards each other. Fingers are easy to be pinched, or even pinched off, which poses a great safety hazard
