Description

Table with expandable table top

Technical Field

The utility model relates to a desk with an expandable desktop.

Background

The table is a common furniture used in homes, offices and the like, and in order to save space and facilitate storage, the table tops of many tables are designed into a foldable or unfoldable structure, such as a hinge mode, a sliding mode and the like. The existing design form has the following problems: the hidden table top can not be used for placing articles in the folded state, so that the purposes of the table top are wasted; when the folding table is converted from the unfolding state to the folding state, the hidden table top articles are required to be completely folded, which is very troublesome.

Disclosure of Invention

In order to solve the problems, the utility model provides a desk with an expandable desktop, which has high utilization rate of the desktop and is convenient to use. The utility model adopts the technical scheme as follows:

a desk with an expandable desktop comprises an upper desktop, a lower desktop, two side plates, a rear plate, front legs and rear legs, wherein the front legs are fixedly connected below the lower desktop, the lower edges of the side plates are hinged to the side edges of the lower desktop, the upper edges of the side plates are clamped in clamping grooves of the upper desktop, the upper edges of the rear plates are fixedly connected with the upper desktop, and the lower edges of the rear plates are slidably inserted into cross beams of the rear legs;

a fixed seat is arranged below the lower desktop, a transverse telescopic rod I and a transverse telescopic rod II are slidably arranged in the fixed seat, the rear end of the telescopic rod I is connected with a rear leg, and a conical spiral guide rail is arranged at the rear end of the telescopic rod II;

and the lower end of the rear plate is provided with a pulley which is in sliding fit with the conical spiral guide rail.

The table with the expandable table top is characterized in that the lower end face of the lower table top and the outer side faces of the side plates are provided with plug bolts. At least two transversely telescopic connecting beams are arranged between the front legs and the rear legs of the table with the expandable table top.

The utility model has the advantages that: a storage space is formed between the upper table top and the lower table top in a folded state, the upper table top is always in a horizontal state when being unfolded, and articles placed in the upper table top do not need to be folded. The upper table top is adjusted and supported through the conical spiral guide rail in the vertical direction, and stable lifting is achieved.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

This embodiment is a desk that desktop can expand, including last desktop 1, desktop 2, two curb plates 3, back plate 4, foreleg 5 and back leg 6 down, foreleg 5 links firmly desktop 2 below down, 3 lower limb of curb plate hinges on desktop 2's side down, the upper limb card is in the draw-in groove of last desktop 1, the upper limb of back plate 4 links firmly with last desktop 1, the lower limb slides and pegs graft in the crossbeam of back leg 6. The upper table top 1 in this embodiment is a rectangular plate of 1000 x 600 mm.

A fixed seat 7 is arranged below the lower tabletop 2, a transverse telescopic rod I8 and a transverse telescopic rod II 9 are slidably arranged in the fixed seat 7, the rear end of the telescopic rod I8 is connected with a rear leg 6, and a conical spiral guide rail 10 is arranged at the rear end of the telescopic rod II 9;

the lower end of the back plate 4 is provided with a pulley 11, and the pulley 11 is in sliding fit with the conical spiral guide rail 10.

In the table with the expandable table top, the lower end surface of the lower table top 2 and the outer side surface of the side plate 3 are both provided with the plug bolts 12. The side panels 3 may also be unfolded and then the side panels 3 supported flat with a bayonet in series.

In the table with the expandable table top, at least two transversely telescopic connecting beams 13 are arranged between the front legs 5 and the rear legs 6.

Combine the three kinds of states in the attached drawing, when making the installation, the biggest elongation of telescopic link II 9 should be less than the biggest elongation of telescopic link I8, and when expanding, telescopic link II 9 is blocked by fixing base 7 after extending to the utmost point maximum state, and lower desktop 2 can't continue to move the extension, rotates toper spiral guide 10 at the rear this moment, and pulley 11 is the slope slip backward along its spiral guide to go up desktop 1 downward and backward motion, finally in desktop 1 parallel and level down. The tapered spiral guide rail 10 is provided at the edge of the table to facilitate the operation without providing a vertically operated elevating mechanism for moving the upper table top 1 up and down. Under fold condition, form the matter storage lattice between upper table top 1 and the lower table top 2, also can place article, stable in structure has improved space utilization.
