Abstract

The utility model provides a picnic desk, it includes desktop board, table frame pipe, batter pipe, sliding sleeve, position sleeve, linkage pipe, bracing pipe, well foot pipe, intermediate head, characterized by table frame pipe is articulated mutually with intermediate head, and desktop board rigid coupling is on table frame pipe, the intermediate head rigid coupling is on well foot pipe, the batter pipe is articulated mutually with table frame pipe, the upper end of bracing pipe is articulated mutually with table frame pipe, and the lower extreme is articulated mutually with the sliding sleeve, be equipped with mutual articulated linkage pipe between batter pipe and the bracing pipe, set three link mechanism to between four -bar linkage and table frame pipe and bracing pipe, the well foot pipe and realize the expansion and fold up through setting to between table frame pipe and batter pipe, bracing pipe, the linkage pipe to the foot pipe is carrying out the mounting spur in setting up through the middle part at the folding table, has strengthened the bending resistance of table frame pipe, and then has improved the bearing capacity of longer desktop, therefore, the utility model has the advantages of simple structure, the desk that occasions such as convenient operation and suitable conduct are camped, courtyard were used.

Description

Picnic table

Technical field

The utility model belongs to field of furniture, particularly a kind of Picnic table.

Background technology

The utility model patent of Chinese patent database announcement on October 1st, 2008, name is called " Combined foldable table ", the patent No. is 200720058276.0, a kind of Combined foldable table, comprise some desktop panels, socle, desktop cross bar, X-shaped travel(l)ing rest, socle top is provided with the head that is fixedly hinged, and on socle, cover has moveable hinge joint; Respectively establish an X-shaped travel(l)ing rest respectively in the described folding table left and right sides, before and after described folding table, two X-shaped travel(l)ing rests are respectively established on two sides respectively, and before and after described folding table, in the middle of two sides, hinged seat is hinged by X-shaped travel(l)ing rest.The folding table of said structure needs desktop extended length when using under special occasions, because middle part does not have the strong point, can be excessive and make desktop recessed because bear moment, and cause desktop out-of-flatness, affect the use of product.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 of long table top set-ups.

The technical scheme that the utility model adopts is: a kind of Picnic table, it comprises desktop, table frame pipe, batter pipe, sliding sleeve, positioning sleeve, linkage tube, down tube, middle pin pipe, transition joint, it is characterized in that four frame pipes are hinged by two transition joint docking, desktop is fixed on a frame pipe; Two transition joints are fixed in one on pin pipe, and middle pin pipe sets firmly two positioning sleeves; Two side legs pipe is hinged with four frame pipes respectively; Upper end and the table frame pipe of four down tubes are hinged, and lower end and sliding sleeve are hinged; The linkage tube be hinged is provided with between two side legs Guan Yusi down tube.

Further, described slide is socketed on middle pin pipe, and is arranged on the side of positioning sleeve away from desktop.

Further, quadric chain is arranged between described table frame pipe and batter pipe, down tube, linkage tube.

Further, three-link mechanism is arranged between described table frame pipe and down tube, middle pin pipe.

The beneficial effects of the utility model are: by being arranged between table frame pipe and batter pipe, down tube, linkage tube be arranged to three-link mechanism realize launch and folding between quadric chain and table frame pipe and down tube, middle pin pipe, and carry out by pin pipe in arranging at the middle part of folding table the support that lands, enhance a bending resistance for frame pipe, guarantee that a frame pipe in use can not be recessed, improve the weight capacity compared with table face.

Detailed description of the invention

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 Picnic table, it comprises desktop 1, table frame pipe 2, batter pipe 3, sliding sleeve 4, positioning sleeve 5, linkage tube 6, down tube 7, middle pin pipe 8, transition joint 9, it is characterized in that four frame pipes 2 dock hinged by two transition joints 9, desktop 1 is fixed on a frame pipe 2; Two transition joints 9 are fixed in one on pin pipe 8, middle pin pipe 8 set firmly two positioning sleeves 5; Two side legs pipe 3 is hinged with four frame pipes 2 respectively; Upper end and the table frame pipe 2 of four down tubes 7 are hinged, and lower end and sliding sleeve 4 are hinged; The linkage tube 6 be hinged is provided with between two side legs pipe 3 and four down tubes 7.

With reference to Fig. 2, constitute quadric chain by table frame pipe 2, linkage tube 6, down tube 7 and batter pipe 3, and constitute three-link mechanism by down tube 7, middle pin pipe 8 and table frame pipe 2, jointly realized expansion or the folding of desk by double leval jib and three-link mechanism.

With reference to Fig. 3, time folding, two transition joints 9 are upwards lifted, angle between a frame pipe 2 and middle pin pipe 8 is diminished, according to Triangle Principle, sliding sleeve 4 along in pin pipe 8 slippage downwards, cause and constitute three-link mechanism by down tube 7, middle pin pipe 8 and table frame pipe 2 and move; Angle between table frame pipe 2 and down tube 7 also changes, and causes to constitute double leval jib by table frame pipe 2, linkage tube 6, down tube 7 and batter pipe 3 and move, and now, folding table is in folded state.

With reference to Fig. 3, when continuing folding, two transition joints 9 are continued upwards to lift, make the angle between a frame pipe 2 and middle pin pipe 8 continue to diminish, until the angle between table frame pipe 2 and middle pin pipe 8 is zero, be namely parallel to each other between two frame pipes 2, now, desk is folded into tabular, smaller volume, is convenient for carrying and deposits.

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