Abstract
Provided is a lumbar support double stroke driver, which belongs to the field of automobile fittings. The lumbar support double stroke driver can increase stay wire stroke by simple rotation. The lumbar support double stroke driver is characterized in that a base of a housing is provided with a base fixing hole; a thread sleeve is inserted in the housing; a left-hand screw thread screw is in a threaded connection with a thread sleeve in the housing; the front end of a plus thread screw is inserted in the left-hand screw thread screw, and the rear end is in a threaded connection with the thread sleeve; a stay wire traverses the left-hand screw thread screw and is clamped in the plus thread screw; a wire jacket sleeving the stay wire is clamped on the left-hand screw thread screw. The lumbar support double stroke driver is advantageous in that the structure is simple and the operation is convenient; brake cable stroke can be raised by one time by only one round of rotation; operation fatigue can be reduced; the hunch-up height of the lumbar support assembly is increased by one time, and the comfortableness is obviously improved.
Description
Technical field
The utility model belongs to the vehicular spare parts field.
Background technology
At present lumbar support mechanism is installed, also cries the waist holder, regulate it and highly can support taking people's waist in the inside of automotive seat; Thereby reduce the fatigue of taking the people; And regulate the waist holder generally be called regulating control, existing regulating control needs several circles of turn when generally regulating repeatedly, cause hand tired easily; Especially chaufeur is easy to generate danger in the process of driving a car.
Summary of the invention
The utility model purpose provides two times of stroke actuators of waist holder that a kind of simple rotation promptly can strengthen the backguy stroke.
The utility model has the bearing fixed orifice on the bearing on the housing; Swivel nut is inserted in the housing, and the minus thread screw rod is threaded with swivel nut in enclosure interior; The plus thread screw front end is inserted in the minus thread screw rod, and the rear end is threaded with swivel nut; Backguy is passed the minus thread screw rod and is stuck in the plus thread screw rod, is enclosed within the outer line cover of backguy and is stuck on the minus thread screw rod.
The utility model is simple in structure, and is easy to operate, only revolves and turns around, and the brake cable stroke can double, and reduces operation fatigue, and waist holder assembly arches upward and highly doubles, and traveling comfort obviously improves.
Description of drawings
Fig. 1 is the utility model structure cutaway view.
The specific embodiment
On the bearing 4 on the utility model housing 6 bearing fixed orifice 7 is arranged; The utility model is fixed on the car at bearing fixed orifice 7 through bolt etc.Swivel nut 5 is inserted in the housing 6, and minus thread screw rod 3 is threaded with swivel nut 5 in housing 6 inside; Plus thread screw rod 8 front ends are inserted in the minus thread screw rod 3, and the rear end is threaded with swivel nut 5; Backguy 1 is passed minus thread screw rod 3 and is stuck in the plus thread screw rod 8, is enclosed within backguy 1 outer line cover 2 and is stuck on the minus thread screw rod 3.
When needs adjusting lumbar support mechanism, rotate swivel nut 5, screw-threaded engagement bonded assembly minus thread screw rods 3 are perhaps middle mobile to two ends respectively with plus thread screw rod 8 respectively with swivel nut 5; The stroke of minus thread screw rod 3 control lines cover 2; Thereby reduce the stroke of backguy 1, so the stroke of plus thread screw rod 8 control backguys 1 is under the effect through minus thread screw rod 3 and plus thread screw rod 8; The stroke of backguy 1 is double walking basically, thereby reduces the rotating cycle of swivel nut 5.
