Adjustable table

Abstract

The invention discloses an adjustable table which is characterized in that four pull pipes are inserted into four upright table legs respectively; a transverse rod is fixed to the upper ends of the pull pipes of the two rear table legs, two hinged seats penetrate the transverse rod, and a base is fixed on the back surface of a table panel; the upper ends of the pull pipes of the two front table legs are fixed on the left side and right side of a table bucket, a supporting plate is fixed on the upper edge of the table bucket, and the front edge of the table panel is arranged on the supporting plate; both the table panel and the supporting plate can be lifted by pulling the pull pipes; the table panel slides back and forth on the supporting plate when the table panel or the supporting plate is separately lifted, so that the tilt degree of the table panel can be changed; oblique bracing plates at the lower ends of the pull pipes are used for positioning; the high ends of the bracing plates are propped against the inner walls of the pull pipes, and the low ends of the bracing plates are propped against the inner walls of the table legs; the low ends of the bracing plates are connected with the lower ends of connecting rods, connecting levers are connected to the upper ends of the connecting rods, and the low ends of the bracing plates are loosened downwards for lifting adjustment; after adjustment, the low ends of the bracing plates are pulled to ascend through the connecting levers to support the inner walls of the table legs again; due to the arrangement of the supporting plate, the defects of difficult operation and inconvenient fetching in the prior art are overcome; due to the arrangement of the connecting levers, the bolt screwing angle during adjustment is changed and the operation is convenient; besides, other defects are overcome.

Description

technical field [0001] The invention relates to a table in furniture, especially a table with adjustable height and inclination of the desktop. Background technique [0002] The table with adjustable tabletop height and inclination brings convenience and health to people.

Problems solved by technology

When it is adjusted to a high position, the desktop moves forward as a whole, and the user will feel cramped and inconvenient to use it, but the space behind the desktop is wasted. In the literature that first applied for "semi-automatic height adjustment desk" (application number: 201210064741.7) For the first time, it is proposed to adjust the inclination of the desktop by changing the height difference between the front and rear table legs, which solves the above problems well, but there are several defects in the technical solution of this patent application

Disadvantages include: 1. The left and right rod supports are adjusted separately, which must be parallel to each other and equal in height, which is troublesome.

2. The area of ​​the rod support is limited to support the user's elbow, which is uncomfortable

3. When raised to a high position, it is inconvenient to place objects away from the desktop board away from the storage board

4. The adjustment parts are exposed outside, and it is easy to be damaged by children who often play with them

The disadvantage is that it is inconvenient to turn the bolts from bottom to top when adjusting; the connection between the components is loose and the stability is poor; the support plate of the core component is permanently connected with the adjacent components through a shaft, which is inconvenient for installation, disassembly and maintenance
