Embodiment

See also Fig. 1 to Fig. 3, but doubling pivot provided by the utility model have a base 10 and a connecting seat 20; Wherein the dull and stereotyped screen of liquid crystal screen and so on is assembled in Connection Block 20 fronts, base 10 then with a plane winding.Fig. 1 has shown Connection Block 20 and base 10 deployed conditions, and Fig. 3 shows base 10 and Connection Block 20 doubled state, transports being fit to.

Base 10 both sides folding face 13 front ends of the utility model

form hole seat

11 and 12 respectively, and two back folding faces 23 of Connection Block 20 also form

hole seat

21 and 22, all are provided with the hole of pivot joint on the seat of hole, and form pivot points at this, articulate with hinge device.

Pivot points in the left side, it is sealed with a nut 44 to pass support sheet 41,

hole seat

11 and 21, shell fragment 42 and pad 43 backs by a screw rod 40, to constitute hinge device, can be referring to Fig. 4, the compressing power that is provided by shell fragment 42, but hole seat 11 rotation and in arbitrary angle location relatively of hole seat 21 phase bases 10 of Connection Block 20 made.

In the right side pivot points except the hinge device that passes support sheet 31,

hole seat

12 and 22, shell fragment 32 and pad 33 and a nut 34 sealed formations with a screw rod 30, in pivot points, still be provided with an adjusting mechanism, it comprises a reinforced sheet 35 and a protruding axle 36 that is located at 22 of base aperture seat 12 and Connection Block hole seats, and a spacer 37 that is located at screw rod 30 medial extremitys.In this position, still be provided with a press device, it has comprised that one passes the pressing lever 381 of hollow screw 30, the nut 383 that a spring 382 and is located at spacer 37 medial surfaces, after wherein pressing lever 381 passes spring 382, hollow screw 30 and spacer 37, the threaded portion 384 and the nut 383 of pressing lever 381 ends lock together, make can make spacer 37 generations of screw rod 30 inboards move by compressing pressing lever 381 outside end faces, can be referring to Fig. 5 and Fig. 6.

Cam 36 in the utility model adjusting mechanism has been offered first slotted eye 361 and second slotted eye 362 on it; Spacer 37 then has a nose bar 371, it stretches in first slotted

eye

361 or 362 of cam 36 after can passing perforate 121 on the base aperture seat 12 and the perforate 351 on the reinforced sheet 35, as shown in Figure 9, only show cam 36 and spacer 37, to know both sides relation.After the nose bar 371 of spacer 37 passes first slotted eye 361 of cam, as shown in Figure 5, can pass the perforate 221 of Connection Block 20 hole seats 22 again, Connection Block 20 relative bases 10 are launched and locate.

Referring to Fig. 7 and Fig. 7 A, first slotted eye, the 361 relative cam horizontal diameter 36h of cam 36 upwards form the first angle θ 1, and form the second angle θ 2 downwards, this effect is to be adjusted to angle of depression θ 1 or elevation angle theta 2 for Connection Block 20, as shown in Figure 8, as the known technology explanation, angle of depression θ 1 is about 5 degree and elevation angle theta 2 is about 10 degree.

When will be with base 10 relative Connection Block 20 harvest doubled state, as shown in Figure 3 during the position, can be earlier pressing lever 381 end faces of press device be imposed pressure shown in Fig. 5 arrow G 1 direction, it is shown in Figure 6 to make that pressing lever 381 shrinks 382 one-tenth of pressuring springs to screw rod 30, make nose bar 371 disengagings of spacer 37 hold to the perforate 221 of Connection Block hole seat 22 and first slotted eye, 361 buttons of cam 36, so base 10 Connection Block 20 relatively rotates to doubling position (as shown in Figure 3), then the nose bar 371 of spacer 37 is just in time in second slotted eye 362 of cam 36, as loosen pressure to pressing lever 381, because the restoring force of spring 382 can make the nose bar 371 of spacer 37 buckle in second slotted eye 362 of cam 36.

Again referring to Fig. 7 and Fig. 7 A, 362 of second slotted eyes on the cam 36 are constituted with a backstop section 362a and a slope section 362b, wherein backstop section 362a is when the nose bar 371 of spacer 37 passes, and base 10 can be positioned at doubled state can't move again, conveniently to transport.But, when will be again Connection Block 20 and base 10 being launched, as long as direct stretching Connection Block, make spacer 37 nose bars 371 along slope section 362b slippage, nose bar 371 is directly stretched in first slotted eye 361 of cam 36, and do not need to oppress pressing lever 381, just Connection Block 20 can be adjusted to the expanded position of relative base 10.

Apparently, but in the doubling formula pivot provided by the utility model, Connection Block 20 and base 10 are easy to do expansion or fold operation, and the angle of depression or the elevation angle of adjustment Connection Block 20, have progressive meaning than known configurations.

Exist, the utility model is provided with a reinforced sheet 35 between rotating cam 36 and base aperture seat 12 again, and reinforced sheet 35 has a button piece 352, and it buckles into another perforate 122 on the base aperture seat 12, to finish combination.Contact with rotating cam 36 by reinforced sheet 35, strengthen function to form backstop, to reduce the damage probability of base aperture seat 12.

Only the most preferred embodiment of the utility model being showed shown in the above drawing, so is not to be to limit the technical scope that the utility model is protected.
