The fixed locking member of cylinder cooperation.
Further, the power device includes pedestal, and the pedestal is equipped with threaded hole, is equipped with screw thread in the threaded hole
Push rod, the screw putter are equipped with locking nut, and the swing arm is equipped with arc groove, is equipped with and the spiral shell in the arc groove
Line push rod cooperation fixed locking member first unclamps locking nut when needing to adjust tensioning wheel position, uses according to the actual situation
Tool adjusts screw putter, and screw putter moves in a straight line in threaded hole, connect screw putter with swing arm by locking member,
Since locking member can move in arc groove with the movement of swing arm, the transform linear motion of push rod is the swing of swing arm, is adjusted
It after section, screws locking nut and fixes screw putter position, so that the position of tensioning wheel be fixed.
Further, the locking member includes lock shaft, and the lock shaft is equipped with through-hole, is equipped with bolt in the through-hole,
Screw putter is connect with swing arm by lock shaft, bolt is inserted into, the both ends of lock shaft can be limited, prevent lock shaft from putting
It is skidded off on arm, guarantees the connection of screw putter and swing arm.
Further, connecting rod, one end of the connecting rod and the pendulum are equipped between the screw putter and the swing arm
Arm connection, the other end are equipped with the set entrance that cooperate with the screw putter, and connecting rod is connected as one with swing arm, when installation,
It needs the set entrance of the top insertion connecting rod of screw putter, installation, convenient disassembly.
In conclusion the utility model adjusts tensioning wheel position by the lever construction of swing arm adjusts belt indirectly
Clamp force, structure is simple, and time saving and energy saving and regulating effect is good.
