When the utility model is used, the expansion ring can be arranged in the bottom of the air chamber, the bottom of the air chamber is formed and positioned by the fixed ring, and the whole air chamber is tensioned by the expansion ring. The utility model has the advantages of simple fabrication, convenient disassembly and carry, good stability, good safety, and convenient transportation.

Description

Portable seat

The utility model relates to a kind of portable base that is used on the pneumatic exploitation device.

Large and medium-sized pneumatic exploitation device is owing to have Gao Erda, thereby also has shortcomings such as the wind resistance face is big, poor stability.In order to increase its stability, way solves to adopt that rope is pullled mostly at present etc., and this had both influenced attractive in appearance, had increased floor area again, and dangerous.

In view of above reason, the purpose of this utility model is that a kind of making is simple, convenient disassembly in order to provide, the portable base of the good stability of dependable performance and pneumatic exploitation matched with devices.

Outside framework is arranged in the utility model, place the circle of deciding on the outside framework, the piston ring (referring to Fig. 1, Fig. 2) that can be connected with air bag and cooperate with fixed circle.

Between above-mentioned outside framework and fixed circle bracing ring is arranged, (referring to Fig. 2) can increase its stability and intensity.

One end of above-mentioned piston ring has adapter sleeve, and the other end of piston ring can stretch in the adapter sleeve and to cooperate (referring to Fig. 3) with adapter sleeve.

The leg that is connected with outside framework is arranged in the above-mentioned base, and there is mounting hole (referring to Fig. 1) the leg lower end.

The scroll wheel (referring to Fig. 1) that is contained on the mounting hole is arranged, conveniently moving on the above-mentioned leg.

Above-mentioned air bag can be the figure of eight or the special-shaped figure of eight, and (referring to Fig. 4) is handsome in appearance, and lucky, is the treasured calabsh shaped shape.

The lower diameter φ of above-mentioned air bag is greater than 500 millimeters, and height H is greater than 1000 millimeters.

The circle of deciding is arranged, piston ring in the utility model.During use, with pack into air bag bottom of piston ring, make setting location, air bag bottom by fixed circle, piston ring is strained whole air bag.As required, the detachable leg of fit on, and can join scroll wheel on the leg also can press weight thereon or with the hole that foundation bolt passes on the leg base fixed.The utility model is made simple, dismantles exploitation matched with devices good stability easy to carry and pneumatic, and security is good, is convenient to transportation and carries.Do not need rope to pull just can stablize and stand in place good looking appearance.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:

Fig. 1: the utility model structural representation,

Fig. 2: outside framework, bracing ring, Ding Quan mutual alignment graph of a relation

Fig. 3: piston ring structural representation

Fig. 4: figure of eight air bag installation diagram

Decide circle 2 referring to being welded with in Fig. 1, Fig. 2, the outside framework 1, outside framework 1 and enclose 2 surely and be welded with bracing ring 3.Piston ring 4 has adapter sleeve 5 as shown in Figure 3 on the one end, the other end of piston ring can stretch in the adapter sleeve 5 and to cooperate with adapter sleeve 5 or fastening with screw 6.Support 7,8 symmetries are installed on the outside framework 1 and with nut 9,10 and fix.Support 7,8 lower ends have on the connecting hole 11,12, and scroll wheel 13,14 is contained in respectively on the support 7,8.During installation, air bag 15 bottoms are placed decide in the circle 2 and be connected the air bag bottom its tensioner is located with piston ring 4.

Referring to Fig. 4, air bag 16 be shaped as " 8 " word treasured calabsh shaped shape (also can be the special-shaped figure of eight), its underpart diameter phi is greater than 500 millimeters, height H is greater than 1000 millimeters.
