Abstract

The utility model relates to a folding table which mainly comprises positioning bases, a table top board, positioning plates, long leg tubes, short leg tubes, connecting tubes, rivets, marbles, end sleeves and extension tubes wherein the positioning bases are arranged on the table top board, the log leg tubes and the short leg tubes are arranged in the positioning bases, the extension tubes are arranged on the long leg tubes, the connecting tubes are arranged on the short leg tubes, and the extension tubes are arranged on the connecting tubes. The table top board, the long leg tubes, the short leg tubes and the connecting tubes constitute a four-link mechanism, and the unfolding and folding of the folding table can be achieved by controlling the four-link mechanism. The folding table has simple structure, is convenient to use and is applicable to the occasions such as camping, sand beaches, courtyards, etc.

Description

Folding table

Technical field

The utility model relates to a kind of desk, particularly a kind of folding table.

Background technology

A kind of common folding table of prior art, the utility model patent that name is called " folding convenient table " was disclosed on November 24th, 1999 such as Chinese patent database, the patent No. is 98250992.8, a kind of folding convenient table, it comprises a desktop, symmetrical two groups of elastic clamp seats of dehiscing and two groups of Ω shape decks of remaining silent of being equipped with on the bottom surface of this desktop, in elastic clamp seat, be plugged into the supporting leg of ∩ shape, install travel(l)ing rest in Ω shape deck, the openend of this travel(l)ing rest and the top of described supporting leg are hinged by hinge.Two groups of supporting legs are the parallel upright state and contact with ground, and supporting desktop, and the upright state of supporting leg fixes by travel(l)ing rest.This upright supporting leg supporting desktop structure, supporting construction is owing to exist movable part, the less stable of folding table desktop; During folding, need to from two groups of elastic clamp seats of dehiscing, take apart supporting leg respectively, operate the problems such as more loaded down with trivial details.For above-mentioned shortcoming, be necessary to make improvement.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of folding table that does not need to dismantle the fold mechanism of table leg to solve the problem of complex operation.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of folding table mainly comprises positioning seat, desktop, spacer, long pin pipe, short pin pipe, tube connector, rivet, hoodle, end cover, telescoping tube; It is characterized in that four positioning seats are fixed on the desktop; Long pin pipe and short pin pipe are installed in the positioning seat; Set firmly spacer on the short pin pipe, an end of tube connector is hinged with short pin pipe, and the other end is provided with the end cover; Long pin pipe is provided with the end cover, and telescoping tube is provided with hoodle, and telescoping tube is placed on long pin pipe and the tube connector; Long pin pipe and tube connector are hinged by rivet.

Described long pin pipe and short pin pipe are U-shaped pipe, can rotate around positioning seat respectively.

Described telescoping tube is U-shaped pipe, and long pin pipe and telescoping tube form annular rigid frame; Short pin pipe and tube connector, telescoping tube form annular rigid frame.

Described desktop, long pin pipe, short pin pipe and tube connector have formed quadric chain.

The beneficial effects of the utility model are: desktop is provided with positioning seat, be provided with long pin pipe and short pin pipe in the positioning seat, long pin pipe is provided with telescoping tube, short pin pipe is provided with tube connector, tube connector is provided with telescoping tube, formed quadric chain by desktop, long pin pipe, short pin pipe and tube connector, motion by the control quadric chain, realize expansion and the folding of folding table, therefore the utlity model has simple in structure, easy to operate and be fit to camp, characteristics that the outdoor occasions such as sandy beach, garden are used.

The specific embodiment

Below by specific embodiment, and by reference to the accompanying drawings the technical solution of the utility model is described further.

Embodiment: with reference to Fig. 1, a kind of folding table mainly comprises positioning seat 1, desktop 2, spacer 3, long pin pipe 4, short pin pipe 5, tube connector 6, rivet 7, hoodle 8, end cover 9, telescoping tube 10; It is characterized in that desktop 2 is provided with positioning seat 1; Positioning seat 1 is provided with long pin pipe 4 and short pin pipe 5; Set firmly spacer 3 on the short pin pipe 5, an end of tube connector 6 is hinged with short pin pipe 5, and the other end is provided with end cover 9; Long pin pipe 4 is provided with end cover 9, and telescoping tube 10 is provided with hoodle 8, and telescoping tube 10 is placed in long pin pipe 4 and the tube connector 6; Long pin pipe 4 is hinged by rivet 7 with tube connector 6.

With reference to Fig. 2, during use, the rigid frame that the rigid frame that long pin pipe 4 and the draw 10 forms and short pin pipe 5, tube connector 6 and telescoping tube 10 form is put up the X-type cross supporting table top board that lands; When desktop 2 placing objects, gravity passes to long pin pipe 4 and short pin pipe 5 by positioning seat 1, long pin pipe 4 passes to ground by telescoping tube 10, short pin pipe 5 passes to ground by tube connector 6 and telescoping tube 10, since tube connector 6 with 4 one-tenth X-type cross settings of long pin pipe, therefore tube connector 6 and and long pin pipe 4 between owing to existing moment of torsion to produce shearing force, at this moment, according to mechanics principle, long pin pipe 4 clockwise rotates around pin joint, and tube connector 6 rotates counterclockwise around interface point, when the spacer 3 on the short pin pipe 5 and tube connector 6 are inconsistent, has limited the rotation of tube connector 6, by desktop 2, short pin pipe 5, tube connector 6, long pin pipe 4 has formed the triangular support framework of rigidity, by the rotation of long pin pipe 4, at this moment, folding table is in the use state after launching.

With reference to Fig. 3, when folding, first desktop 2 is inverted on the ground, regulate first the hoodle 8 on the telescoping tube 10, make telescoping tube 10 difference convergent-divergents in tube connector 6 and long pin pipe 4.

With reference to Fig. 4, when continuing to fold, will lack pin pipe 5 and clockwise rotate around positioning seat 1, make tube connector 6 break away from spacers 3, drive thus tube connector 6 and rotate around short pin pipe 5; The rotation of tube connector 6 drives long pin pipe 4 and rotates, and the quadric chain that is comprised of desktop 2, short pin pipe 5, tube connector 6, long pin pipe 4 moves, and at this moment, folding table produces folding, in the folded state.

With reference to Fig. 5, when continuing to fold, short pin pipe 5 continues to rotate around positioning seat 1, until short pin pipe 5 fits with desktop 2, make long pin pipe 4, tube connector 6 be in same plane with short pin pipe 5, and parallel with desktop 2 respectively, at this moment, folding table is folded into flat, and smaller volume is convenient for carrying and transports.
