Abstract
The utility model provides an adjustment hand wheel displaying the weight. The adjustment hand wheel comprises a hand wheel bottom cover, a hand wheel top cover, an inner gear and an outer fluted disc, wherein the hand wheel bottom cover is connected with the hand wheel top cover in a close fit mode to form a shell, a clamping spring, a limiting block, an inner gear fixing base, a center penetrating pin and a protecting cover are arranged inside the shell, the hand wheel top cover is connected with a driving shaft through the center penetrating pin, and the driving shaft is connected with a screw connection part. By using the adjustment hand wheel displaying the weight, stiffness of a damping suspension of a seat is changed by rotating the hand wheel, the seat is suitable for people with different weights, and comfort is enhanced. Meanwhile, a displayed weight range can be visually seen, and operation is simple, convenient, rapid and reliable.
Description
Technical field
The utility model relates to a kind of mechanical shock absorption seat load capacity control apparatus, especially a kind of control hand wheel that shows weight.
Background technology
The core component of mechanical shock absorption seat suspension is application spring shock absorption, at spring diameter, in the constant situation of the number of turns and rigidity, the impression that the people of different weight takes is different, it is soft that somebody feels, somebody feels firmly, must be therefore adjustable by seat suspension rigidity Design.
Existing mode is that, for different human body weight, corresponding regulating spring, in different displacement section work, still owing to cannot seeing intuitively weight result, regulates very hard.
Summary of the invention
The purpose of this utility model is to provide a kind of control hand wheel that shows weight, in the time of rotation hand wheel, by screw mandrel and screw transmission, changes spring displacement, according to the linear variable relation of spring, displacement is converted into weight and on handwheel, shows.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: a kind of control hand wheel that shows weight, comprise handwheel bottom, handwheel top cover, inner gear, outer tooth disk, it is characterized in that: described handwheel bottom and handwheel top cover form housing with tight fit connection, in housing, be provided with jump ring, limiting stopper, inner gear permanent seat, punching pin, protecting cover, handwheel top cover is connected with axle drive shaft by punching pin, and axle drive shaft is connected with screw connecting piece.
Beneficial effect:
Use the control hand wheel of demonstration weight described in the utility model, rotation hand wheel changes seat shock-proof suspension rigidity, is applicable to Different Weight people and takes, and improves traveling comfort.Can see intuitively shown weight range simultaneously, easy and simple to handle, rapidly, reliable.
Brief description of the drawings
Fig. 1 is that principle of work of the present utility model is shown in figure.
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention
The utility model as shown in Figure 2 shows the control hand wheel of weight, comprise handwheel bottom 4, handwheel top cover 7, inner gear 5, outer tooth disk 6, described handwheel bottom 4 and handwheel top cover 7 form housing with tight fit connection, in housing, be provided with jump ring 1, limiting stopper 2, inner gear permanent seat 3, punching pin 8, protecting cover 9, handwheel top cover 7 is connected with axle drive shaft 10 by punching pin 8, and axle drive shaft 19 is connected with screw connecting piece 11.
Control hand wheel as shown in Figure 2, propulsive effort transmittance process is: handwheel bottom 4 and handwheel top cover 7 are with tight fit connection, handwheel top cover 7 is connected with axle drive shaft 10 by punching pin 8, axle drive shaft 10 is connected with screw connecting piece 11, in the time rotating handwheel bottom 4, propulsive effort just passes to the screw mandrel screw mechanism of shock-proof suspension, transmits by screw mandrel and screw engagement, to rotatablely move and be transformed into straight-line motion, thereby change spring displacement.
Digital display process is: handwheel top cover 7 flange portions are gears (being called Z1), and radial symmetry is arranged two teeth; Two inner geares 5 (being called Z2) symmetry is contained in inner gear permanent seat 3, and inner gear permanent seat 3 is coaxial with axle drive shaft 10, and fixing with limiting stopper 2, has static scale scale above; Outer tooth disk 6 (being called Z3) is coaxial with axle drive shaft 10.There is dynamic graduated scale above.In the time that handwheel top cover 7 rotates, Z1 drives Z2, and Z2 drives Z3, rotates thereby realize digital display dish, and the corresponding line of static scale scale and dynamically graduated scale is the weight range of demonstration.
