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, Fig. 2, a kind of folding table mainly comprises desktop 1, a frame pipe 2, screw 3, rise pipe 4, extension 5, gear shift seat 6, pin pipe 7, footmuff 8, hoodle 9, adapter 10, lowers pipe 11, stull pipe 12, gear shift pipe 13, heel brace pipe 14, beam pipe 15, lands and manage 16; It is characterized in that a frame pipe 2 and beam pipe 15 are fixed together forms the quadrilateral frame of rigidity, and desktop 1 is installed on a frame pipe 2 by screw 3; An end that raises pipe 4 is hinged with table frame pipe 2, and the other end is installed on adapter 10; Adapter 10 is socketed on stull pipe 12; One end of extension 5 is hinged with table frame pipe 2, and the other end is provided with hoodle 9, and is placed in pin pipe 7; One end of pin pipe 7 is provided with gear shift seat 6, and the other end is installed with footmuff 8, and pin pipe 7 is provided with a plurality of hoodles hole 71; Set firmly stull pipe 12 between gear shift seat 6; Land pipe 16 two ends are provided with footmuff 8, and an end and the pin pipe 7 of the pipe 16 that lands are hinged, and the other end is managed 11 and is hinged with lowering; Lower the quadrilateral frame that has formed rigidity between pipe 11 by gear shift pipe 13 and heel brace pipe 14; Gear shift pipe 13 is installed on gear shift seat 6.

With reference to Fig. 3, described gear shift seat 6 is provided with long slot bore 61, deck I62, deck II63, deck III64, deck IV65, short slotted eye 66, locating hole 67; It is characterized in that can being installed in deck I62, deck II63, deck III64, deck IV65 with the gear shift pipe 13 of lowering pipe 11 Joints, pin pipe 7 is installed in long slot bore 61, and stull pipe 12 is installed in short slotted eye 66, and by locating hole 67 Joints.

With reference to Fig. 4, during use, when the hoodle hole 71 on hoodle 9 and pin pipe 7 fastened, the length of side at extension 5 places immobilized, the length of side that raises pipe 4 and table frame pipe 2 places is solid value, therefore by table frame pipe 2, raise the triangle mechanism supporting table top board 1 of the rigidity that pipe 4 and extension 5 form; Each limit length of side of managing 11 places due to the pipe 16 that lands, downward is solid value, and after gear shift pipe 13 and gear shift seat 6 fasten, the length of side at pin pipe 7 places also is solid value, therefore by pin pipe 7, the pipe 16 and lower triangle mechanisms that pipe 11 forms rigidity and support by table frame pipe 2, raise the triangular support mechanism that pipe 4 and extension 5 form of landing, be in the use state after making the folding table expansion.

With reference to Fig. 5, during use, when regulating gear shift pipe 13 clamped position different from gear shift seat 6, by by pin pipe 7, the pipe 16 and lower and manage 11 triangular shaped the changing that form of landing, at this moment, the angle run-off the straight of desktop 1.

With reference to Fig. 6, when folding, the gear shift pipe 13 that first will lower on pipe 11 is extracted in gear shift seat 6, and clockwise rotates to the pipe 16 that lands; The pipe 16 that will land again rotates counterclockwise, and draws close to pin pipe 7.

With reference to Fig. 7, when continuing to fold, the hoodle hole 71 of regulating on hoodle 9 and the pin pipe 7 on extension 5 is separated, make extension 5 convergent-divergents in pin pipe 7, the length of side at extension 5 places is shortened, by Triangle Principle as can be known, in the triangle mechanism that table frame pipe 2, rise pipe 4 and extension 5 form, the corresponding angle of extension 5 diminishes, and namely raises pipe 4 and rotates counterclockwise, and draw close to table frame pipe 2.

With reference to Fig. 8, when continuing to fold, continue to regulate extension 5, make the length of side at extension 5 places continue to shorten, by Triangle Principle as can be known, in the triangle mechanism that table frame pipe 2, rise pipe 4 and extension 5 form, the corresponding angle of extension 5 continues to diminish, and coincides with table frame pipe 2 until raise pipe 4, and the angle that namely raises between pipe 4 and table frame pipe 2 is zero, rotate again the pipe 16 that lands, and it is abutted against on stull pipe 12, at this moment, folding table is in flat form, smaller volume, convenient storage and transportation.

Above-described embodiment is a kind of preferred version of the present utility model, is not 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.
