Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in figs. 1-7, a kind of waist support mechanism of electrodeless lock support, including waist support 1 and mating connection are after waist support 1
The supporter of side, supporter include front support lid 2 and rear support lid 3, and rear support lid 3 is equipped with the first self-tapping screw 4 and preceding branch
Support lid 2 is fixedly connected.
As preferred structure, front support fixed column 5 is fixedly installed in 2 two sides of front support lid, and sliding is matched in front support fixed column 5
Front support slide post 6 is closed, front support slide post 6 and the interference fit of waist support 1 connect, and front support slide post 6 and support column 12 are mutual
With merging under the elastic force effect of spring 11, waist support 1 can be made to slide back and forth.
As preferred structure, rear support fixed column 8 is fixedly installed in 3 two sides of rear support lid, and fixation is set in rear support fixed column 8
Have a limited post 10, limited post 10 be equipped with one group certain group away from limit hole 18, limited post 10 and the socket of spring 11 cooperate, spring
11, which are forced through limited post 10, squeeze flexible and generate deformation.11 front end of spring contacts cooperation support column 12, support column 12
Front end contacts cooperation front support slide post 6, active force of the front support slide post 6 by waist support 1, and support column 12 is slided by front support
The active force of dynamic column 6, spring 11 is supported the active force of column 12 and deformation occurs, at this point, support column 12 and 10 sets of limited post
Connect cooperation；In addition, 12 rear end of support column, which contacts, is equipped with opening, the internal diameter of opening is adapted with the outer diameter of limited post 10, support column
The outer diameter that 12 rear ends contact is adapted with the internal diameter of rear support fixed column 8；Position-limit mechanism, position restrainer are equipped in the middle part of rear support lid 3
Structure includes gag lever post 14, shaft coordinating block 9, plectrum 13 and the rotation axis 15 that can cooperate with the limit hole 18 on limited post 10,
The setting of shaft coordinating block 9 is in the middle part of rear support lid 3, and be rotatably assorted rotation axis 15 on shaft coordinating block 9, and fixation is set in rotation axis 15
Plectrum 13 is set, gag lever post 14 is fixedly installed in 13 both ends of plectrum.12 stress of support column and squeeze spring 11 so that support column 12 is limiting
Gap between position column 10 and rear support fixed column 8 slides back and forth, if there is gag lever post 14 to pass through limit hole 18, the rear portion of spring 11
Divide deformation that will be fixed, the sliding distance of support column 12 is also limited to the preceding part of spring 11.
In order to control the rotation of gag lever post 14, front support, which covers, is equipped with switching handle 19 and compatible with switching handle 19

In pedestal 16, so that limited post 10 is capable of fixing on rear support lid 3.
The course of work of the utility model will be further described below:
The utility model is mounted on an office chair back, in use, people rests in waist support 1, is not had in switching handle 19
When having locking, 1 stress of waist support and since the interaction of power by front support slide post 6 and support column 12 occurs spring 11
Deformation, can the sitting postures of all around different directions lumbar support can be provided, and waist support 1 can give people one elastic force, allow people
Generate comfort；It is supported when needing for waist support to be fixed on a certain position in use, people, which leans against, makes the back of oneself in waist support 1
In oneself ideal position, deformation occurs for 11 stress of spring, to limit at this point, rotating rotation axis 15 by switching handle 19
Steel pole 14 cuts limit hole 18 and a part of deformation of spring 11 is fixed, and the spring 11 of another part remains to so that waist support 1
It gives people one elastic force, can achieve the purpose that the fixed adjustment of front-rear position；Squeezing waist support 1 makes the spring 11 of the left and right sides that difference occur
Deformation, the same different deformation part by springs 11 at left and right sides of 19 pairs of handle of switching is fixed, and waist support 1 is just in a left side
Right-oblique location status can achieve the purpose that the fixed adjustment of left-right position.
