A stop lock reset structure of a paper towel dispenser and a paper towel dispenser

Abstract

The application discloses a paper towel dispenser stop locking reset structure and a paper towel dispenser, which comprises a base, a ratchet wheel, a stop block and an elastic reset part, the base is provided with a first connecting part; the ratchet wheel rotates relative to the base, the ratchet wheel is eccentrically provided with a second connecting part; the stop block is in stop engagement with the ratchet wheel; the elastic reset part comprises a first coil spring and a second coil spring which are oppositely arranged, and a third coil spring which is arranged on one side between the first coil spring and the second coil spring, two extension connecting ends of the third coil spring are connected with one extension connecting end of the first coil spring and the second coil spring respectively, the other extension connecting end of the first coil spring and the second coil spring extends to the opposite side of the third coil spring and is connected to the first connecting part together, and the third coil spring is sleeved on the second connecting part. The multi-point stress alleviates the critical point generated by the one-way stress, reduces the spring fatigue and fracture influence, reduces the reset error, and prolongs the service life.
