Abstract

The utility model relates to a drum-shaped telescopic stool. An upper shell and a lower shell of the drum-shaped telescopic stool can be tightly engaged to form a hollow round drum which is halved, an upper guide track is arranged at the top of the upper shell, and a lower guide track is arranged at the bottom of the lower shell; roller wheels are arranged at the two ends of an upper end transverse shaft at the upper end of a scissors-shaped lifting erector and are in rolling matching with and loaded into the upper guide track; and roller wheels are arranged at the two ends of a lower end transverse shaft at the upper end of the scissors-shaped lifting erector and are in rolling matching with and loaded into the lower guide track; and positioning grooves are arranged on the two sides of the lower guide track. The upper surface of the upper shell is a downwardly recessed spherical surface, and the lower surface of the lower shell is an inwardly recessed surface; and a tightening device and a lifting handle matched with the lower shell are arranged on the two sides of the lower end of the upper shell. The drum-shaped telescopic stool can be hidden inside a drum-shaped box after being folded, and has small volume, esthetic appearance and convenience for carrying. Also, the height of the stool surface is adjustable.

Description

Cydariform shrinks stool

Technical field

The utility model relates to a kind of portable stool, and particularly a kind of cydariform shrinks stool.

Background technology

Existing portable stool mostly is and exposes open type, goes out to carry inconvenience, not attractive in appearance; And their height can not be regulated.

Summary of the invention

The purpose of this utility model provides a kind of being hidden in the cydariform box, and the cydariform that can regulate height shrinks stool.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of cydariform shrinks stool, its upper shell and lower house are formed half-and-half separately, the hollow circle drum of closely interlock, are provided with upper rail at the top of described upper shell, are provided with lower guideway in the bottom of described lower house.Roller is equipped with at two ends at described scissor lift frame upper end transverse axis, and the roller of upper end transverse axis rolls and cooperates in the upper rail of packing into; Roller is equipped with at two ends at described scissor lift frame lower end transverse axis, and the roller of lower end transverse axis rolls and cooperates in the lower guideway of packing into, is provided with locating slot on the both sides of lower guideway.Be provided with tightening device and the handle that cooperates with lower house in both sides, upper shell lower end.The upper surface of described upper shell is for following concave spherical surface, and is more comfortable during seat.The lower surface of described lower house is an inner concave, and is more stable on the feasible placement ground.The square toes alignment pin of described tightening device can slide in the mating holes of upper shell, and the other end of square toes alignment pin is a dead bolt, and dead bolt cooperates with the corresponding lockhole of lower house; The spring leaf that is fixed on upper shell presses the square toes alignment pin that draw ring is housed.

During use, pull out the square toes alignment pin, hold handle, upwards lift upper shell, when the scissor lift frame launched, the roller at transverse axis two ends, lower end entered the locating slot on lower guideway both sides, and the height of scissor lift frame is locked, can sit people or placement weight on the stool face.If roller enters the locating slot in the middle of the lower guideway, then the height of stool face is bigger.In the time of need not needing to draw in, two lift and outwards gently draw the scissor lift frame on hand, the roller at transverse axis two ends, lower end, leave the locating slot on lower guideway both sides, slide to the two ends of lower guideway, upper shell descend and with the tight interlock of lower house, under spring leaf presses thrust, the dead bolt of the square toes alignment pin other end inserts the corresponding lockhole of lower house automatically.

The beneficial effects of the utility model are:

1. be hidden in the cydariform box after the contraction stool folds, volume is little, and it is easy to carry, attractive in appearance to go out.

2. the stool face that shrinks stool is Height Adjustable.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

Embodiment 1 is shown in Fig. 1-5: a kind of cydariform shrinks stool, and its upper shell 1 and lower house 5 are formed half-and-half separately, the hollow circle drum of closely interlock, are provided with upper rail 2 at the top of described upper shell 1, are provided with lower guideway 6 in the bottom of described lower house 5; Roller 3 is equipped with at two ends at described scissor lift frame 4 upper end transverse axis 11, and the roller 3 of upper end transverse axis rolls and cooperates in the upper rail 2 of packing into; Roller 3 is equipped with at two ends at described scissor lift frame 4 lower end transverse axis 12, and the roller 3 of lower end transverse axis rolls and cooperates in the lower guideway 6 of packing into; Be provided with locating slot 7 on the both sides of lower guideway 6; Be provided with tightening device and the handle 13 that cooperates with lower house 5 in both sides, upper shell 1 lower end.

The upper surface of described upper shell 1 is for following concave spherical surface, and is more comfortable during seat.The lower surface of described lower house 5 is an inner concave, and is more stable on the feasible placement ground.

Embodiment 2 is shown in Fig. 2-3: the square toes alignment pin 9 of described tightening device can slide in the mating holes of upper shell 1, and the other end of square toes alignment pin 9 is a dead bolt, and dead bolt cooperates with the corresponding lockhole of lower house 5; The spring leaf 8 that is fixed on upper shell 1 presses the square toes alignment pin 9 that draw ring 10 is housed.Described tightening device also can adopt hasp general on the case and bag or clinching.

During use, pull out square toes alignment pin 9, hold handle 13, upwards lift upper shell 1, when scissor lift frame 4 launches, the roller 3 at transverse axis two ends, lower end, enter the locating slot 7 on lower guideway both sides, the height of scissor lift frame 4 is locked, can sit the people or place weight on the stool face.If roller 3 enters the locating slot 7 in the middle of the lower guideway, then the height of stool face is bigger.In the time of need not needing to draw in, two lift and outwards gently draw scissor lift frame 4 on hand, the roller 3 at transverse axis two ends, lower end leaves the locating slot 7 on lower guideway both sides, slides to the two ends of lower guideway 5, upper shell 1 descend and with lower house 5 tight interlocks, press under the thrust at spring leaf 8, the dead bolt of square toes alignment pin 9 other ends inserts the corresponding lockhole of lower house 5 automatically, upper shell 1 and lower house 5 are closely locked, unite two into one.
