Abstract

The utility model provides a scalable campstool solves prior art and uses inconvenient scheduling problem, and its technical scheme is, including supporting cloth, to support the cloth both ends and fix on controlling two bracing pieces, the telescopic link has all been welded at the both ends of every bracing piece, and the other end of telescopic link links to each other with the section of thick bamboo that stretches out and draws back, and the flexible other end links to each other with lower telescopic link, and the bottom welding of lower telescopic link has lower support rod, the utility model discloses simple structure, portable, convenient to use, it is with low costs, not only can fold and to stretch out and draw back, be more convenient for carrying under the travel condition such as play.

Description

Scalable campstool

Technical field

This utility model relates to campstool field, a kind of scalable campstool.

Background technology

Campstool is common the articles for daily use, either out on tours or park enjoy the cool when its figure all can occur, existing campstool supported by left and right side and be connected to left and right side support between supporting surface binder form, the two ends of supporting surface binder are fixedly connected on left and right side by nail respectively and support, its shortcoming is, campstool can only folding and not flexible, be still inconvenient to carry in the case of not using.

Summary of the invention

For solving technical problem present in above-mentioned technology, this utility model provides a kind of scalable scalable campstool being convenient for carrying, and solving prior art can only fold, it has not been convenient to carry problem.

Its technical scheme is, including supporting cloth, supports cloth two ends and is fixed on two support bars of left and right, the two ends of every support bar are all welded with expansion link, the other end of expansion link is connected with retracting cylinder, and the other end of retracting cylinder is connected with lower expansion link, and the bottom of lower expansion link is welded with lower support bar.

This utility model simple in construction, it is simple to carry, easy to use, low cost, be possible not only to fold also flexible, travelling of being more convenient for play when carry.

Accompanying drawing explanation

Fig. 1 is front view of the present utility model.

Fig. 2 is the upward view of Fig. 1.

Detailed description of the invention

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.

As depicted in figs. 1 and 2, scalable campstool, including supporting cloth 3, support cloth 3 two ends to be fixed on two support bars 2 of left and right, the two ends of every support bar 2 are all welded with expansion link 1, the other end of expansion link 1 is connected with retracting cylinder 4, and the other end of retracting cylinder 4 is connected with lower expansion link 6, and the bottom of lower expansion link 6 is welded with lower support bar 5.

Described upper support bar 2, lower support bar 5 are parallel to each other.

Described support cloth 3 is fixed with upper support bar 2 by nail.

Described upper expansion link 1, lower expansion link 6 are slidably connected with retracting cylinder 4, and end is mounted on spring catch.

Described retracting cylinder about 4 two ends all have pin-and-hole 7, are front and back connected by hinge bar 8 between two retracting cylinders 4.

This utility model is during routine use, during up-down stretch, when the spring catch on upper and lower expansion link enters into the pin-and-hole in retracting cylinder, expansion link ensures the stability of structure by not being stretched again, expansion link can be pushed again after Manual press spring catch during compression, thus reach flexible purpose；This utility model, upon deployment in " x " type, relies on support cloth to support the weight of user, uses simple and convenient, economical and practical.
