Description

A kind of 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 existing 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 long joint chair, long pin pipe, screw, short circuit seat, tube connector, positioning seat, short pin pipe, desktop; It is characterized in that desktop is provided with two groups of long joint chairs that be arranged in parallel and short circuit seat; The long pin pipe of riveted joint on the long joint chair; Riveting pipe on the short circuit seat; The other end riveted joint positioning seat of tube connector, hinged short pin pipe on the positioning seat; Short pin pipe and long pin pipe are hinged by screw.

Described long joint chair comprises locating surface I, locating hole I, interval trough I, long cantilever, hinge hole I, and locating surface I and desktop fit, and screw passes locating hole I and is fixed on the desktop; Long pin pipe is placed in the interval trough I, and screw passes hinge hole I and is hinged with long pin pipe.

Described short circuit seat comprises locating surface II, locating hole II, interval trough II, long cantilever, hinge hole II, and locating surface II and desktop fit, and screw passes locating hole II and is fixed on the desktop; Tube connector is placed in the interval trough II, and screw passes hinge hole II and tube connector is hinged.

Described long pin pipe is U-shaped pipe, by having formed rigid frame between long joint chair and the desktop.

Described short pin pipe is U-shaped pipe, has formed rigid frame by tube connector and short circuit seat and desktop.

Formed quadric chain between described desktop, tube connector, short pin pipe and the long pin pipe, this quadric chain has limited the direction of motion of four connecting rods by positioning seat; When long pin pipe and short pin pipe land when stressed, when short pin pipe and tube connector turned to a straight line and be in the dead-centre position of four connecting rods, positioning seat had limited the rotation direction between short pin pipe and the tube connector.

The beneficial effects of the utility model are: long joint chair and short circuit seat are set on the desktop, long joint chair is provided with long pin pipe, the short circuit seat is provided with tube connector, tube connector is provided with positioning seat, short pin pipe is set on the positioning seat, thereby make between desktop, tube connector, short pin pipe and the long pin pipe and formed four connecting rod fold mechanisms, 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 long joint chair 1, long pin pipe 2, screw 3, short circuit seat 4, tube connector 5, positioning seat 6, short pin pipe 7, desktop 8; It is characterized in that desktop 8 is provided with long joint chair 1 and short circuit seat 4; The long pin pipe 2 of riveted joint on the long joint chair 1; Riveting pipe 5 on the short circuit seat 4; The other end riveted joint positioning seat 6 of tube connector 5, hinged short pin pipe 7 on the positioning seat 6; Short pin pipe 7 and long pin pipe 2 are hinged by screw 3.

With reference to Fig. 2, described long joint chair 1 comprises locating surface I11, locating hole I12, interval trough I13, long cantilever 14, hinge hole I15, and locating surface I11 and desktop 8 fit, and screw 3 passes locating hole I12 and is fixed on the desktop 8; Long pin pipe 2 is placed in the interval trough I13, and screw 3 passes hinge hole I15 and is hinged with long pin pipe 2.

With reference to Fig. 3, described short circuit seat 4 comprises locating surface II41, locating hole II42, interval trough II43, long cantilever 44, hinge hole II45, and locating surface II41 and desktop 8 fit, and screw 3 passes locating hole II42 and is fixed on the desktop 8; Tube connector 5 is placed in the interval trough II43, and screw 3 passes hinge hole II45 and tube connector 5 is hinged.

With reference to Fig. 4, during use, 7 one-tenth X-type cross of long pin pipe 2 and short pin pipe land, and long pin pipe 2 is by long joint chair 1 supporting table top board 8; Short pin pipe 7 is by positioning seat 6, tube connector 5 and short circuit seat 4 supporting table top boards 8.

With reference to Fig. 5, formed quadric chain by desktop 8, tube connector 5, short pin pipe 7 and long pin pipe 2, when desktop 8 is stressed, cause producing between short pin pipe 7 and the long pin pipe 2 flared trend, because the limit function of positioning seat 6, limited short pin pipe 7 this moment around the rotating counterclockwise of positioning seat 6, limited simultaneously tube connector 5 and clockwise rotated around positioning seat 6, thereby made folding table launch to use.

With reference to Fig. 6, when needs are folding, make first the desk reversing, desktop 8 is landed, tube connector 5 is clockwise rotated around positioning seat 6, short pin pipe 7 is rotated counterclockwise, at this moment around positioning seat 6, formed quadric chain by desktop 8, tube connector 5, short pin pipe 7 and long pin pipe 2 and moved, desk is in folded state.

With reference to Fig. 7, continue foldingly, short pin pipe 7 is paralleled with long pin pipe 2 and be in same plane, tube connector 5 parallels with desktop 8, and at this moment, folding table is folded into flat, and smaller volume is convenient for carrying and transports.

Above-described embodiment is a kind of preferred version of the present utility model, is not the utility model is done any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technical scheme that claim puts down in writing.
