Embodiment

A kind of manual four-way waist support mechanism shown in 1 referring to the drawings, including waist supporting plate 1, fixed mount, adjustable shelf and control Device 7.

The adjustable shelf includes upper beam 4, underbeam 5 and the connecting rod 6 being connected between upper beam 4 and underbeam 5, the waist supporting plate 1 is installed between upper beam 4 and underbeam 5；

The fixed mount includes first and fixes the fixation steel wire 3 of steel wire 2 and second, and the first fixation steel wire 2 is linear, Second fixation steel wire 3 takes the shape of the letter U, two terminations of the second fixation steel wire 3 and be each passed through the both ends of upper beam 4 and underbeam 5 with First fixes the lower section connection of steel wire 2, and upper beam 4 and underbeam 5 can slide up and down along the both sides of the second fixation steel wire 3（Phase can be designed The slide block structure of cooperation）, so waist supporting plate 1 is flexibly connected with fixed mount together with adjustable shelf.

Shown in reference picture 2, the controller 7 includes housing and handle 71, be provided with the housing axle center it is relative before Rotating shaft 73 and rear rotating shaft 74, the Handle axis 72 of the handle 71 sequentially pass through the axle center of front rotary shaft 73 and rear rotating shaft 74 and in handle Preceding stuck point and rear stuck point are correspondingly provided with axle 72, shown in reference picture 3, the preceding stuck point is included along 72 same circle distribution of Handle axis Four front projections 75, it is described after stuck point include along 72 same circle distribution of Handle axis four rear projections 77.

The inner ring of the front rotary shaft 73 is provided with four semi-enclosed preceding bayonet sockets 76 with the adjacent of preceding stuck point, rear rotating shaft 74 The adjacent of inner ring and rear stuck point is provided with four semi-enclosed rear bayonet sockets 78,

When handle 71 in housing relative to pushing away（Such as Fig. 2 and Fig. 3 state）, front projection 75 connects with corresponding preceding bayonet socket 76 Close（Bayonet socket is semi-enclosed result, is obstructed and can not continue to move to after protruding out into bayonet socket, then connects corresponding rotating shaft and Handle axis It is connected together）, front rotary shaft 73 is static with the coaxial rotating of handle 71, rear rotating shaft 74（Between front rotary shaft 73 and rear rotating shaft 74 and housing Torsion spring 79 is equipped with, in the case that handle 71 is not rotated or corresponding bayonet socket neck is not engaged, front rotary shaft 73 or rear rotating shaft 74 Self-locking is realized by the frictional force between torsion spring 79 and shell）.

Similarly, shown in reference picture 4, when handle 71 outside housing relative to drawing, the rear projection 77 and corresponding rear bayonet socket 78 engagements, rear rotating shaft 74 are then static with the coaxial rotating of handle 71, front rotary shaft 73.

The first wire drawing 8 is connected with rotating shaft 74 after described, is connected with the second wire drawing 9 on the front rotary shaft 73, described first The upper end of wire drawing 8 through the first extension spring 10 of middle upper part of the upper beam 4 with being fixed on underbeam 5 vertically is connected；Second wire drawing 9 The first fixation steel wire 2 through fixed mount is connected with upper beam 4, and the middle lower section of the underbeam 5 and the second paddy for fixing steel wire 3 The second extension spring 11 is connected between bottom vertically.

The course of work of the present utility model is as follows：

1st, the fore-and-aft direction regulation of waist supporting plate：

Shown in reference picture 4, handle 71 pulls out, then rear projection 77 engages with rear bayonet socket 78, and rear rotating shaft 74 and Handle axis 72 are same Axle rotates, and front rotary shaft 73 is static；The first wire drawing 8 that rotating shaft 74 connects after rotary handle 71 causes is tightened up, then shown in reference picture 5 （Dotted line is the first wire drawing variation track）, part outwardly convex of first wire drawing 8 between upper beam 4 and underbeam 5, and then withstand waist Supporting plate 1 causes waist supporting plate 1 to heave to the waist of suitable radian support passenger；The first wire drawing can then be loosened by reversely rotating handle 71 8, in the presence of the first extension spring 10 so that the radian that waist supporting plate 1 is heaved reduces, until loosening reinstatement completely.It is so real Projection and recovery of the existing waist supporting plate 1 in fore-and-aft direction.

2nd, the above-below direction of waist supporting plate is highly adjusted：

Shown in reference picture 1, handle 71 does not pull out, and the state in the interior push-in housing of controller 7, now front projection 75 Engaged with corresponding preceding bayonet socket 76（As shown in Fig. 2, Fig. 3）, front rotary shaft 73 then rotates together with Handle axis 72, and rear rotating shaft 74 is quiet Only；Rotary handle 71 causes the second wire drawing 9 that front rotary shaft 73 connects to tighten up, then the second wire drawing 9 pulls up upper beam 4, Jin Ertong Crossing connecting rod 6 drives underbeam 5 to be moved up together along fixed mount, and also displacement raises waist supporting plate 1 therewith, and the second of the lower section of underbeam 5 draws Spring 11 changes balance therewith；Handle is reversely rotated, loosens the second wire drawing 9, then again in the presence of the second extension spring 11, waist supporting plate 1 returns Restore the height of coming.So realize lift in height of the waist supporting plate 1 in above-below direction.

It is described above, the only preferable embodiment of the utility model, but scope of protection of the utility model is not limited to In this, any one skilled in the art is in the technical scope that the utility model discloses, the change that can readily occur in Change or replace, should all cover within the scope of protection of the utility model.Therefore scope of protection of the utility model is with claim The protection domain of book is defined.
