Abstract

A squeezing structure for water-absorbent swab, comprising a stem, a fixing seat, a roller shaft, a locating bar, a link, a pull handle and a foam rubber. The center of the roller shaft is disposed with an axially extending shaft rod. Multiple rollers are fitted around the shaft rod by stages. An outer circumference of the roller is formed with multiple axially extending and annularly arranged slipproof bodies. An end face of the roller and a lateral side of the roller contain an arch shoulder angle. The roller shafts with the stripes roll on the surface of the foam rubber so as to accurately squeeze and tension the foam rubber and effectively drain the water from the foam rubber. Furthermore, the arch shoulder angle of the end face of the roller tenderly contacts with the foam rubber without hooking or tearing the foam rubber.

Claims

1. A squeezing structure for water-absorbent swab, comprising a stem, a fixing seat, two roller shafts, a locating bar, a link, a pull handle and a foam rubber, the fixing seat being disposed at a bottom end of the stem, the two roller shafts being rotatably disposed on the fixing seat, the locating bar being disposed between the two roller shafts, the top end of the locating bar being disposed with two links which pass through the fixing seat to pivotally connect with the pull handle, the foam rubber being clamped between the bottom sides of the locating bar, said squeezing structure having the improvement in that the center of the roller shaft is disposed with an axially extending shaft rod, multiple rollers being fitted around the shaft rod by stages, an outer circumference of the rollers being formed with multiple axially extending and annularly arranged stripes, an end face of the rollers and a lateral side of the rollers containing an arch shoulder angle.

2. A squeezing structure for water-absorbent swab as claimed in claim 1, wherein the stripes of the rollers are dented stripes.

3. A squeezing structure for water-absorbent swab as claimed in claim 1, wherein the stripes of the rollers are spiral stripes.

4. A squeezing structure for water-absorbent swab, comprising a stem, a fixing seat, two roller shafts, a locating bar, a link, a pull handle and a foam rubber, the fixing seat being disposed at a bottom end of the stem, the two roller shafts being rotatably disposed on the fixing seat, the locating bar being disposed between the two roller shafts, the top end of the locating bar being disposed with two links which pass through the fixing seat to pivotally connect with the pull handle, the foam rubber being clamped between the bottom sides of the locating bar, said squeezing structure having the improvement in that the center of the roller shaft is disposed with an axially extending shaft rod, multiple rollers being fitted around the shaft rod by stages, an outer circumference of the rollers being formed with multiple axially extending and annularly arranged protuberances, an end face of the rollers and a lateral side of the rollers containing an arch shoulder angle.
