Extruding force is recalled, that is, the drag size that the sliding axle is subject to is adjusted, changes the complexity of the sliding axle sliding.
The present invention also provides a kind of preferred embodiments of resistance regulation method:
Using a kind of resistance regulation method described in the drag regulator embodiment of the present invention as described above, including following step
It is rapid:
Step S100, the positioning bar 210 on movable axis 100 is caught in the card slot 110 on pedestal 200.
Specifically, the movable axis 100 is shaft, and the movable axis 100 is inserted into the pedestal 200 and the adjusting group
In the movable axis hole that part 300 is formed, and the positioning bar 210 is directed at the card slot 110, and be caught in the card slot 110
In.At this moment, the shaft can rotate in given area around its axial line, and when rotation, the positioning bar 210 is in the card slot
Sliding, the positioning bar 210 can not continue to rotate when turning to 110 both ends of card slot in 110.Because without the wear-resistant block
360 pressing, friction is small suffered by the shaft at this time, and the rotation of the shaft is relatively easy to.
Further, the movable axis is sliding axle, and the movable axis 100 is inserted into the pedestal 200 and the adjusting
In the movable axis hole that component 300 is formed, the sliding axle can slide axially；Because of the pressing without the wear-resistant block 360, at this time
Friction is small suffered by the sliding axle, and the sliding of the sliding axle is relatively easy to.
Step S200, rotation knob assembly 310 adjusts the resistance that movable axis 100 is subject to.
Step 200 specifically includes:
Step S210, resistance that movable axis 100 is subject to is judged whether less than a preset threshold, if so, thening follow the steps
S220, if it is not, thening follow the steps S230；
Further, step 220 or step 230 can be executed according to the user's choice, i.e., adjust institute according to the user's choice
State the drag size of movable axis 100.
Step S220,310 compression elastic piece 340 of knob assembly is rotated, wear-resistant block 360 is made to compress movable axis 100, increases and lives
The resistance that moving axis 100 is subject to.
Specifically, rotate the knob assembly 310, that is, rotate the knob body 311, the threaded rod 312 along with
Knob body 311 rotates, and generallys use and rotates clockwise, due on the external screw thread and the briquetting 330 on the threaded rod 312
Internal screw thread be it is matched, the briquetting 330 under the drive that the threaded rod 312 rotates can along the guiding rib 321 to
100 direction of movable axis is mobile, and the briquetting 330 is moved along the threaded rod 312 to 100 direction of movable axis in other words
Dynamic, then the briquetting 330 squeezes the elastic component 340.The elastic component 340 will apply extruding force, institute to the jacking block 350
It states jacking block 350 and is moved together along the guiding rib 321 to 100 direction of movable axis with the wear-resistant block 360.It is described wear-resisting
First frictional groove 361 of block 360 is close to the side of the movable axis 100, and the movable axis 100 receives the wear-resistant block
360 pressure increases, and the movable axis 100 is in rotation or sliding, 360 contact surface of the movable axis 100 and the wear-resistant block
The frictional force of generation just increases, i.e., the resistance that the described movable axis 100 is subject to increases.By continuing to rotate the knob body
311 can increase the resistance that the movable axis 100 is subject to.
Step S230, rotation knob assembly 310 decompresses elastic component 340, and wear-resistant block 360 is made to loosen movable axis 100, reduces and lives
The resistance that moving axis 100 is subject to.
Specifically, the knob body 311, the drive that the briquetting 330 is rotated in the threaded rod 312 are rotated counterclockwise
Under moved along the guiding rib 321 to far from the direction of the movable axis 100, the briquetting 330 is along the spiral shell in other words
Rasp bar 312 is mobile to the direction far from the movable axis 100, and the briquetting 330 decompresses the elastic component 340, the elastic component
340 rebounds.The elastic component 340 will reduce the extruding force of the jacking block 350, first friction of the wear-resistant block 360
Slot 361 loosens the movable axis 100, and the movable axis 100 is reduced by the pressure of the wear-resistant block 360, the movable axis 100
The frictional force generated with 360 contact surface of wear-resistant block is reduced by, i.e., the resistance that the described movable axis 100 is subject to reduces.It is logical
It crosses and continues to rotate the knob body 311 and can reduce the resistance that the movable axis 100 is subject to.
In conclusion a kind of drag regulator provided by the present invention and method, described device include: movable axis, if
The pedestal in the movable axis side is set, and the movable axis other side is set for adjusting the tune of the movable axis resistance
Save component；The adjusting component includes: elastic component, and described elastic component one end is arranged in for compressing the set of knobs of the elastic component
