Abstract

The invention provides a clamping type hand crank device for a parasol, which comprises a hand crank, a rope rolling shaft, a shell, an upper central bar, a shaft sleeve, a gasket, a spring, a clamp pin, a rivet, a tumbler device and a lower central bar. The hand crank is characterized in that a lug boss is arranged on the hand crank for clamping and fixing a rope. The shell is provided with a groove matched with the lug boss of the hand crank. The lug boss of the hand crank is clamped in or separated from the groove of the shell to control the rotation of the rope rolling shaft so as to retract, release and position a parasol rope. The invention provides the clamping type hand crank device for the parasol, which has the advantages of simple structure, good stability, rapid assembly and good antiskid effect and solves the technical problems in the prior art such as complex structure, cumbersome assembly, high time and labor consumption as well as poor antiskid effect and stability.

Description

technical field [0001] The invention belongs to the technical field of umbrella accessories, and in particular relates to a clip-type hand swing device for a sun umbrella. Background technique [0002] The existing hand shaking device is composed of many parts, has a complex structure, cumbersome assembly, labor and time-consuming, and the anti-slip effect is not very good, the stability is poor, and the cost is high. Moreover, the existing hand-shaking device is separated from the pipe cover that the upper and lower middle sticks are plugged in, which is not very attractive in appearance, and the cost of the umbrella is relatively increased simultaneously. Contents of the invention [0003] The object of the present invention is to provide a snap-type handle device for sun umbrellas with simple structure, good stability, fast assembly and good anti-slip effect, which solves the complex structure, cumbersome assembly, labor-intensive and time-consuming problems in the prio...
