Description
Technical field
The utility model relates to Seat lumbar technical field, refers in particular to a kind of Seat lumbar actuator.
Background technology
Existing automobile waist holder actuating device, there are rotary-type actuating device and linear pattern actuating device, the stressed shortcoming such as unstable when rotary-type actuating device exists and uses effort, rotates, a lot of design corporations all trend towards designing linear pattern, but linear pattern actuating device also has the restriction of its use occasion and usage space.At present, the patent application of rotary-type actuating device is little, can not use for reference too much part.The special present patent application that proposes of applicant.
Utility model content
The purpose of this utility model is to provide a kind of Seat lumbar actuator for the deficiencies in the prior art, and it is existing that this Seat lumbar actuator has solved existing waist holder actuating device: volume is large, propulsive effort is large, complex structure, the not high defect of commonality.
For achieving the above object, the utility model is achieved through the following technical solutions:
Seat lumbar actuator, comprises protecgulum, bonnet, rotating mechanism, and rotating mechanism middle part is platform, and handle, fixed leg lay respectively at the both sides of platform, and handle passes outside protecgulum; On platform, there is limiting block, limiting block and fixed leg homonymy; In bonnet, have fixing sleeve column, fixing sleeve column overcoat is provided with coiling piece, and coiling piece has wire casing; The fixed leg of rotating mechanism inserts in fixing sleeve column; The side of coiling piece has the limiting section coordinating with limiting block, and the inner ring of torsion spring is assemblied in nest outside, clamped being installed between limiting section, limiting block in two ends of torsion spring.
On platform, also there is spiral pad portion, spiral pad portion and fixed leg homonymy.
Platform also has rotation stopper, has with rotation stopper and coordinate spacing protrusion in bonnet.
The lateral wall of fixing sleeve column has multiple protuberances; The outside of fixing sleeve column is arranged with nest, and the madial wall of nest has multiple recesses, and the protuberance of fixing sleeve column embeds in recess.
The gear of bending outside the two ends directed diameter of torsion spring.
On protecgulum, there are two symmetrically arranged wire holes.
The beneficial effects of the utility model are: rotary handle, promote torsion spring inner ring and expand and can make like a cork to wind the line piece rotation, drive drag-line to move, have simple and compact for structure, self-lock ability strong, the feature of rapid operation.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
Seeing Fig. 1---Fig. 9, the utility model Seat lumbar actuator comprises: protecgulum 1, wire hole 11, fixing sleeve column 12, protuberance 121, bonnet 2, rotating mechanism 3, limiting block 31, rotation stopper 311, spiral pad portion 312, handle 32, fixed leg 33, coiling piece 4, limiting section 41, wire casing 42, nest 5, recess 51, torsion spring 6.
On protecgulum 1, there are two wire holes 11, be symmetrical arranged, can freely select one of them wire hole 11 that the drag-line that drives use is installed.
Between protecgulum 1 and bonnet 2, be provided with rotating mechanism 3, rotating mechanism 3 middle parts are platforms, and handle 32, fixed leg 33 lay respectively at the both sides of platform, and handle 32 passes outside protecgulum 1.Wherein, on platform, there is limiting block 31, on platform, also there is spiral pad portion 312, limiting block 31, spiral pad portion 312 are all positioned on the platform with fixed leg 33 the same sides, the similar torsion spring 6 of spiral pad portion 312, from low toward high spiral, can support torsion spring 6 and keep assembling not tilt, play and promote the atwirl effect of torsion spring 6.Limiting block 31 is for spacing to torsion spring 6, and spiral pad portion 312 facilitates torsion spring 6 rotary works.Platform also has rotation stopper 311, has with rotation stopper 311 and coordinate spacing protrusion in bonnet 2.
In bonnet 2, have fixing sleeve column 12, the lateral wall of fixing sleeve column 12 has multiple protuberances 121; The outer coiling piece 4 that is arranged with of fixing sleeve column 12, coiling piece 4 has wire casing 42, and wire casing 42 is for taking up drag-line; The side of coiling piece 4 has the limiting section 41 of protrusion, and limiting section 41 coordinates with the limiting block 31 of rotating mechanism 3, and torsion spring 6 is clamped to be installed between limiting section 41, limiting block 31.
The outside of fixing sleeve column 12 is arranged with nest 5, and the madial wall of nest 5 has multiple recesses 51, and the protuberance 121 of fixing sleeve column 12 embeds in recess 51.The inner ring of torsion spring 6 is assemblied in nest outside, the gear of bending outside the two ends directed diameter of torsion spring 6, clamped being installed between limiting section 41, limiting block 31 in two ends of torsion spring 6.
