Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings and by embodiment.
This utility model embodiment Disassembling sofa leg automatic recycling device mechanical extending device is made up of mechanical extending device, switching device, described mechanical extending device is prior art, mechanical extending device has identical left-hand side part, right side members, and left-hand side part is connected by fixed component is fixing with right side members.As a kind of special case, the left-hand side part of described mechanical extending device, right side members are provided with returns power axis of rotation part 5 and spring 11 automatically, rotate square tube 9 to be rotationally connected with sitting frame installing plate 12 by the first rotating shaft 7, automatically return power axis of rotation part 5 to be fixed in rotation square tube 9, spring 11 one end is arranged on seat frame installing plate 12 by the first spring mounting hole 4, and the other end is arranged on by the second spring mounting hole 6 and automatically returns on power axis of rotation part 5.
Enlarged drag-line switch 1 is made up of drag-line switch housing 14, drag-line switch tongue 15, drag-line switching center axle 16 and drag-line switch torsion spring 17, the drag-line switch tongue 15 of enlarged drag-line switch 1 is provided with stay cord hole 151, stay cord 2 one end is stuck in stay cord hole 151 by round metal stigma 21, the metal buckle 23 of stay cord 2 other end is arranged on cable support 8 by the first drag-line installing hole 3, and the plastic buckle 22 on stay cord 2 is fixed on seat frame installing plate 12 by the second drag-line installing hole 10.Cable support 8 is rotatedly connected by the second rotating shaft 13 with sitting frame installing plate 12, the switching device of composition mechanical extending device.It is bigger than the most common drag-line switch that enlarged drag-line switchs 1 monnolithic case, drag-line switch tongue 15 rotational angle α is more than regular tap rotational angle β (see Fig. 4, Fig. 5), and resistance arm (distance between drag-line switching center axle 16 centrage and stay cord hole 151 centrage) D is longer, add the stroke of switch, enable to cross brandreth flex point easily and open brandreth leg；Enlarged drag-line switch 1 increases power arm length L of drag-line switch tongue 15, L Yu D ratio switchs ratio more than common drag-line, and user just can open leg by less power.
User stirs enlarged drag-line switch 1 stretching stay cord 2, the cable support 8 being connected with stretching 2 rotates around the second rotating shaft 13, to power F automatically returning power axis of rotation part 5 and producing a direction as shown in Figure 1, automatically return power axis of rotation part 5 stress to rotate around the first rotating shaft 7, thus the leg realizing mechanical extending device is opened.After unclamping drag-line switch tongue 15, switching and reset under the effect of drag-line switch torsion spring 17, cable support 8 also resets under the effect of cable support torsion spring 20 and returns to initial position.
When the first rotating shaft 7 is positioned on straight line same with spring 11, this utility model embodiment is in and automatically reclaims and the critical point (as shown in Figure 2) opened, when the first rotating shaft 7 is below spring 11, spring 11 forces mechanical extending device to produce the power automatically reclaiming leg, by the motion mode of Fig. 2 to Fig. 1, when moving to limiting bush 18 and automatically returning motion stopping when the confined planes 19 on power axis of rotation part 5 contacts, the i.e. automatic recovery of leg, when the first rotating shaft 7 is above spring 11, spring 11 forces mechanical extending device to produce the power that leg is opened, by the motion mode of Fig. 2 to Fig. 3, i.e. the fully opening of leg.
Every simple deformation of the present utility model or equivalent transformation, it is considered that fall into protection domain of the present utility model.
