Spring-loaded governor and the operation principle of basketball stands that this utility model embodiment is provided are as described below:
As shown in Figure 6, when needs reduce backboard height, swinging handle counterclockwise, the second bevel gear (driving gear) exists
Rotating counterclockwise under the drive of handle, the second bevel gear rotated counterclockwise drives the first bevel gear (driven gear) dextrorotation
Turn, and the first bevel gear is coaxially connected with the axle section of connecing of screw rod so that screw rod turns clockwise with the first bevel gear.This
Time, adjusting nut moves upward towards screw spiral, and drives the inner tube being secured to connect to move upward.Due to basketball backboard bar
With column pivot joint, one end that now basketball backboard bar is connected with inner tube is upturned, and its other end is downward-sloping, and drives basket
Plate down reduces, it is achieved that reduce the purpose of backboard height.On the other hand, backboard and the ring being arranged on backboard are subject to downwards
Gravity, when inner tube moves upward, the basketball backboard bar that up tilts drives pull bar to move upward so that be set on pull bar
Spring compressed, the spring compressed can drive pull bar to move downward so that the gravity of backboard and ring is to power transmission machine
The pulling force that structure brings is buffered so that the load of power transmission mechanism is mitigated so that inner tube rises more steady, more convenient
Quickly, and extend use service life of power transmission mechanism, improve security reliability further.
As it is shown in fig. 7, when needs raise backboard height, swinging handle clockwise, the second bevel gear (driving gear) exists
Turning clockwise under the drive of handle, the second bevel gear turned clockwise drives the first bevel gear (driven gear) to revolve counterclockwise
Turn, and the first bevel gear is coaxially connected with the axle section of connecing of screw rod so that screw rod rotates counterclockwise with the first bevel gear.This
Time, adjusting nut moves downward towards screw spiral, and drives the inner tube being secured to connect to move downward.Due to basketball backboard bar
With column pivot joint, one end that now basketball backboard bar is connected with inner tube is downward-sloping, and its other end is upturned, and drives basket
Plate up raises, it is achieved that raise the purpose of backboard height.On the other hand, when inner tube moves downward, still in pressured state
Spring be slowly released, the Spring driving pull bar being released moves downward.Now, the direction of motion of pull bar and inner tube
The direction of motion is consistent, counteracts the gravity of backboard and ring, facilitates the pulling force of power transmission mechanism simultaneously so that backboard rises
Lighter, power transmission mechanism motion is more steady, convenient quickly, and the use extending power transmission mechanism uses
In the life-span, improve security reliability further.
It will be apparent to those skilled in the art that can technical scheme as described above and design, make other various
Corresponding change and deformation, and all these change and deformation all should belong to the protection of this utility model claim
Within the scope of.
