As shown in Fig. 3, Fig. 4, Fig. 7, the periphery of each fan-shaped desktop 1 is provided with a side groove 11, is provided with a bending plate 4 in side groove 11.Bending plate 4 comprises transverse slat 41 and riser 42, transverse slat local 43 upwards bending forms a breach 44, the design of breach 44 is the considering of bolt convenient fixing when table leg is installed, and the transverse slat local 43 upwards part of bending is provided with interior hinge hole 46, riser 42 is provided with an outer hinge hole 45, and interior hinge hole 46,45 deads in line of outer hinge hole, and inside and outside hinge hole 45 is symmetrical about the plane of symmetry of fan-shaped desktop 1.Bending plate 4 with the concrete matching relationship of side groove 11 is: transverse slat 41 is close to the bottom surface of fan-shaped desktop 1, perpendicular version 42 is close to the periphery of fan-shaped desktop 1, transverse slat part 43 is positioned at side groove 11, breach 44 reserves an opening communicating with side groove in the below of side groove 11, now the axis of interior hinge hole 46, outer hinge hole 45 is positioned on the plane of symmetry of fan-shaped desktop 1, is also on the plane of symmetry of side groove.
As shown in Fig. 3, Fig. 5, Fig. 6, each fan-shaped desktop 1 also comprises a hinged-support 51, dwang and at least one elastic plate 53; Dwang comprises transverse bar 522 and longitudinal rod 521, one end of longitudinal rod 521 be fixedly connected to form T shape dwang vertical with transverse bar 522, and the other end of longitudinal rod 521 is free end; The central longitudinal cross section of transverse bar 522 is square, and two end sections are circular; Dwang is by two ends and the hinged formation revolute pair of hinged-support 51 of transverse bar 522; One end of elastic plate 53 is fixedly connected with hinged-support 51, and the other end is free end, and the longitudinal section that this free end compresses transverse bar 522 is all the time the surface upward of square part 523.Hinged-support 51, dwang, elastic plate 53 structure adjusting angle mechanism 5 in 90 °;
As shown in Figure 3,90 ° of adjusting angle mechanisms 5 are fixed on the T connected in star place of fan-shaped desktop 1 by hinged-support 51, wherein the transverse bar 522 of dwang is positioned at the radial groove 121 of T connected in star, longitudinal rod 521 movement locus one end of dwang end in the tangential groove 122 of T connected in star, and the other end ends in the plane of symmetry of fan-shaped desktop 1;
As shown in Fig. 2, Fig. 8, each fan-shaped desktop 1 also comprises that 2, one bolt ecto-entads of a U-shaped leg are successively through U-shaped leg 2, outer hinge hole 45, interior hinge hole 46, and one end of U-shaped leg 2 and fan-shaped desktop 1 is hinged.The other end of U-shaped leg 2 is fixedly connected with the free end of the longitudinal rod of dwang 521;
As shown in Fig. 1, Fig. 9, three fan-shaped desktops 1 are connected to form round desktop between two by two hinges 3, and the rotation direction of any two adjacent hinges 3 is contrary, the tangential groove 122 of two fan-shaped desktop 1 correspondences that wherein the downward hinge 3 of rotation direction connects is opposing, and the tangential groove 122 of two fan-shaped desktop 1 correspondences that the hinge 3 that rotation direction makes progress connects is relative.
The present embodiment combines by the simple parts such as desktop, 90 ° of adjusting angle mechanisms 5, table leg, articulated elements, and overall structure is fairly simple, and cost is low.Each fan-shaped desktop is interrelated between two by articulated elements, in use, as long as any U-shaped table leg of rotation can realize desktop deployed condition as shown in Figure 1 to the conversion of the folded state shown in Fig. 9, also there is the conversion from Fig. 6 to Figure 10 in the state of 90 ° of adjusting angle mechanisms in transfer process.Due to the fan-shaped desktop of 90 ° of adjusting angle mechanisms 5 restriction can only be in horizontal or vertical a kind of, guaranteed the resistance to overturning of desk.
Embodiment bis-:
The difference of the present embodiment and embodiment mono-is:
1) round desktop of the present embodiment comprises four identical fan-shaped desktops, and the central angle size of each fan-shaped desktop is 90 °.The equal correspondence of each fan-shaped desktop is provided with a U-shaped leg, 90 ° of adjusting angle mechanisms and a bending plate simultaneously;
2) in the present embodiment because fan-shaped desktop quantity is increased to four, thereby hinge need be increased to three and four fan-shaped desktops could be connected to form to round desktop between two, but the installation relation of hinge still meets following rule, that is: the rotation direction of any two adjacent hinges is contrary, the tangential groove that wherein two fan-shaped desktops of the downward gemel connection of rotation direction are corresponding is opposing, and the tangential groove that two fan-shaped desktops of the gemel connection that rotation direction makes progress are corresponding is relative.
3) also there is variation in 90 ° of adjusting angle mechanisms in the present embodiment.As shown in Figure 11, Figure 12,90 ° of adjusting angle mechanisms in the present embodiment comprise a hinged-support 51, dwang and an elastic plate 53; Dwang comprises transverse bar 522 and longitudinal rod 521, vertical being fixedly connected with in one end of one end of longitudinal rod 521 and transverse bar 522, and the other end of longitudinal rod 521 is free end; The other end longitudinal section of transverse bar 522 is square; Dwang is by transverse bar 522 and the hinged formation revolute pair of hinged-support 51; One end of elastic plate 53 is fixedly connected with hinged-support 51, and the other end is free end, and the longitudinal section that this free end compresses transverse bar 522 is all the time the surface upward of square part 523.
The present embodiment combines by the simple parts such as fan-shaped desktop, 90 ° of adjusting angle mechanisms, table leg, articulated elements, and overall structure is fairly simple, and cost is low.Each fan-shaped desktop is interrelated between two by articulated elements, in use, as long as any U-shaped table leg of rotation can realize foldable table top state to the conversion of deployed condition, also there is the conversion from Figure 11 to Figure 12 in the state of 90 ° of adjusting angle mechanisms in this transfer process.Because 90 ° of adjusting angle mechanisms limit a kind of that fan-shaped desktop can only be in horizontal or vertical, guaranteed the resistance to overturning of desk.
Above-described embodiment is described the preferred embodiment of the present invention; not scope of the present invention is limited; design under the prerequisite of spirit not departing from the present invention; various distortion and improvement that those of ordinary skills make technical scheme of the present invention, all should fall in the definite protection domain of the claims in the present invention book.
