In order to maintain the non-inclination state of the round stool surface 10, the stool is also provided with four square long metal plates 6, one end of each square long metal plate 6 is connected with the long pin shafts 3, and the other end of each square long metal plate 6 is connected with short pin shafts 2.

Description

A kind of rescue stool

Technical field

The utility model relates to the stool in a kind of daily life, particularly a kind of stool with jack function.

Background technology

Close stool before the utility model is the spiral stool that is placed in the circular face in hall in coffee shop, bank etc., and a disc is arranged above this stool, and there is a screw rod vertical direction, rotary the centre, and the following of bar is fixed support.By the screw rod that rotates, the height of stool is changed.This stool screw rod does not have the function of jack in the direct load-bearing of vertical direction.

The instrument close with the utility model is a kind of scissors jack that is equipped with through the car of being everlasting, and this scissors jack has horizontal, a rotary lead screw in the centre.Rotate this lead screw, can the very heavy object of jack-up.This jack can not be worked as stool and be used.

The utility model content

The purpose of this utility model is a kind of stool with jack function of invention, can work as stool at ordinary times and sit, and particular time can be worked as jack and be used.

The purpose of this utility model is achieved in that slightly does improvement with the scissors jack, installs a disc at an upper portion thereof additional, is to move easily after it is extruded (for example earthquake) in case select the purpose of disc.The lower part is to support the bottom surface, slightly makees improved scissors jack in the centre.

Described mid portion has 8 rectangle metallic plates that two ends are porose, and 8 metallic plates intersect to form 4 X-shaped shapes mutually, and these 4 X-shaped shapes are 2 of vertical direction stacks, and horizontally-arranged is 2 in the horizontal direction, connects moulding with 6 axles of having strong market potential.Wherein be processed with screw in the middle of two of the centre position axles of having strong market potential, the long filament bar of screwing on two screws, an end spiral lines of long filament bar are positive silk, and other end spiral lines is anti-silk.The spiral lines of two screws on the long filament bar is consistent with the spiral lines of corresponding that terminal filament bar.In order to keep circular stool face not tilt, 4 block length square metal plates also are housed in addition, an end of rectangle metallic plate connects the axle of having strong market potential, and the other end connects short pin shaft.So just constituted the bracing frame of mid portion stool.When rotating the metal lead screw, will cause the change of two screw distances on the screw mandrel, can cause that the X-shaped shape narrows down or broadens, thereby cause the change of bracing frame height.

Because adopt technique scheme, the utility model has possessed stool and two kinds of functions of jack.The utility model can be placed on the automobile, under the mine.Can work as stool at ordinary times and sit, particular time can be worked as jack and be used.When imagination took place at Wenchuan earthquake, the stool in the classroom in Beichuan middle school was the utility model, had that more fresh and alive life obtains saving oneself.

Description of drawings

Fig. 1 is the structural principle schematic diagram of the utility model embodiment; This figure is made of upper, middle and lower three parts, and top is divided into a circular face, and the lower part is one and supports the bottom surface that mid portion is slightly to make improved scissors jack.

The specific embodiment

Below in conjunction with accompanying drawing and the specific embodiment the utility model is done and to be described in further detail.

As shown in Figure 1, this figure is made of upper, middle and lower three parts, and top is divided into a circular stool face 10, and the lower part is a support bottom surface 8, and mid portion can be considered as former and later two faces, and these two faces are symmetrical, so only with the front its structure is described.Front at mid portion, 4 rectangle metallic plates 4 that two ends are porose are arranged, 4 metallic plates 4 intersect to form the X-shaped shape in twos and superpose at vertical direction, the hole at 4 metallic plate 4 two ends with 6 have strong market potential the axle 1,3 with circular stool faces 10, the support bottom surface 8 link into an integrated entity, be processed into screw in the middle of two axles 3 of having strong market potential, the 2 threads bars 7 of screwing on two screws, 7 spiral lines of long filament bar are positive silk, and another root spiral lines be anti-.Spiral lines on two screws is consistent with the spiral lines of corresponding that terminal filament bar.Thick cylinder 9 with holes of welding in the middle of the long filament bar 7, the hole on the thick cylinder 9 are for inserting the usefulness that other circular metal bar (for example Phillips screwdriver) rotates long filament bar 7.Door glove box 11 is fixed on and supports on the bottom surface 8, and some aids as Phillips screwdriver and so on can be put in the inside.

When the hole when insert thick cylinder 9 with Phillips screwdriver on is rotated it, drive the rotation of long filament bar 7, cause the change nearly (or far away) of the screw distance of two axles 3 of having strong market potential, thereby cause that circular stool face 10 uprises (or low).

In order to keep circular stool face 10 not tilt, the utility model also is equipped with rectangle metallic plate 6, sees clearly for convenience, and the light rectangle of rectangle metallic plate 6 usefulness band oblique line is drawn among Fig. 1.One end of rectangle metallic plate 6 connects the axle 3 of having strong market potential, and the other end connects short pin shaft 2.Notice that 2 of short pin shafts connect two block length square metal plates, the metallic plate of its discord back connects.The axle 3 of having strong market potential has connected 4 block length square metal plates.

Described mid portion constitutes: 4,4 rectangle metallic plates 6 of 8 porose rectangle metallic plates in two ends are linked into an integrated entity with circular stool face 10, support bottom surface 8 by 3 and 4 short pin shafts 2 of axle (obverse and reverse of noting Fig. 1 respectively has two short pin shafts 2) of having strong market potential of 41,2 band screws of having strong market potential.The axle 3 long filament bars 7 of screwing on of having strong market potential of 2 band screws are welded with thick cylinder 9 with holes in the middle of the long filament bar 7.The utility model has 12 block length metallic plates altogether, connects with 10 long and short bearing pins.All long metal sheets can rotate around length (or short) bearing pin separately.
