Preferably, a rotating handle is fixedly mounted on the outer end of the rotating shaft.
Preferably, a first bolt for fixedly connecting the rope is fixedly installed on the first fixing seat.
Preferably, the rope connecting member is a second bolt, and the top end of the second bolt is in threaded fit with the sliding sleeve.
Has the advantages that: compared with the pneumatic waist among the prior art holds in the palm guiding mechanism, the utility model discloses a mechanical system realizes that the waist holds in the palm the regulation, not only cost greatly reduced, and moreover, the function is reliable, can increase substantially the riding comfort of passenger seat, has good application prospect, is suitable for and popularizes and applies on passenger seat on a large scale.
Drawings
Fig. 1 is a schematic view of an embodiment of the present invention;
fig. 2 is a partially enlarged view of fig. 1.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
Example (b):
referring to fig. 1 and 2, the waist support adjusting mechanism for the car seat according to the embodiment includes a first fixing seat 3, a second fixing seat 8, a rope 4, and a rope adjusting mechanism assembled on the second fixing seat 8. First fixing base 3 and second fixing base 8 all adopt the angle steel preparation to be provided with a plurality of pilot hole. The rope 4 is a steel wire rope.
As shown in fig. 2, the rope adjusting mechanism includes a fixed sleeve 9, a sliding sleeve 15, a rotating shaft 13 and a second bolt 14, and a rotating handle 11 is fixedly mounted on the outer end of the rotating shaft 13 through a fastening bolt 12. The fixed sleeve 9 is transversely arranged and fixedly connected on the second fixed seat 8, the sliding sleeve 15 is assembled in the fixed sleeve 9 in an inserting mode, the inner end of the rotating shaft 13 is assembled in a threaded hole in the center of the sliding sleeve 15, the outer end of the rotating shaft penetrates out of the fixed sleeve 9, an annular clamping groove is formed in the position connected with the fixed sleeve 9, a clamping spring 10 is assembled in the annular clamping groove, and the clamping spring 10 is used for enabling the rotating shaft 13 to only do rotary motion and not to do axial motion. The bottom of the fixed sleeve 9 is provided with an axial long hole 16, the upper end of the second bolt 14 penetrates through the long hole 16, and the second bolt is assembled on the sliding sleeve 15 in a threaded mode.
First bolt 2 is fixedly installed on first fixing base 3 through fixation nut 1. One end of the rope 4 is fixed on the first bolt 2 of the first fixed seat 3, and the other end is connected on the second bolt 14.
As shown in fig. 1, when the seat is installed and used, the first fixing seat 3 and the second fixing seat 8 are fixed on a back frame (not shown) of the car seat, one end of the rope 4 connected with the first bolt 2 is a fixed end, and one end connected with the second bolt 14 is a movable end.
