Description

U-shaped air expansion shaft

Technical Field

The utility model relates to an inflatable shaft field, concretely relates to U type inflatable shaft.

Background

The inflatable shaft is a special winding and unwinding shaft, namely a shaft with a protruded surface after high-pressure inflation, and a shaft with a quickly retracted surface part after deflation is called an inflatable shaft, and the prior inflatable shaft with Chinese publication number of CN201801236U discloses the technology: the air expansion reel shaft body is provided with a plurality of axial grooves, the longitudinal walls of the grooves are provided with clamping tables, air bags are axially placed at the bottoms of the grooves, an I-shaped jacking piece is clamped above the air bags, and an elastic sheet is arranged between the bottom table of the I-shaped jacking piece and the clamping tables; the axial insertion gap is formed in the shaft body, but in the prior art, only one air expansion shaft can be arranged on one winding machine when large-batch production is performed, the production efficiency is low, and efficient production cannot be achieved.

SUMMERY OF THE UTILITY MODEL

To the problem, the utility model provides a U type inflatable shaft.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: the novel inflatable shaft comprises a shaft body, wherein a shaft head is arranged at the upper end of the shaft body and fixedly connected with the shaft body, a key strip is arranged on the outer surface of the shaft body and embedded in the outer surface of the shaft body, a U-shaped pipe is arranged below the shaft body, and an inflation inlet is formed in the U-shaped pipe.

Furthermore, the shaft body is internally provided with an air bag, one end of the air bag is provided with an air inlet, and the other end of the air bag is provided with an air outlet.

Further, a buckle is arranged below the shaft body.

Further, a bearing is arranged above the U-shaped pipe.

Furthermore, the venthole with the outside intercommunication of axis body and intercommunication department are provided with the valve.

From the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages:

the utility model provides a U type inflatable shaft, the setting of the inflation inlet on U type pipe and the U type pipe for need can aerify two inflatable shafts simultaneously at the during operation, thereby can use two inflatable shafts to carry out work simultaneously, improved gas filled speed, increased the efficiency of work.

fig. 1 is an overall schematic view of the present invention;

FIG. 2 is a schematic view of the inside of the shaft body of the present invention;

in the figure: the shaft body-1, the shaft head-2, the air vent-3, the key strip-4, the U-shaped pipe-5, the inflation inlet-6, the air bag-7, the air inlet-8, the bearing-9 and the buckle-10.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the following drawings and embodiments are connected to further illustrate the present invention in detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Examples

Referring to fig. 1 and 2, a U-shaped inflatable shaft comprises a shaft body 1, a shaft head 2 is arranged at the upper end of the shaft body 1, the shaft head 2 is fixedly connected with the shaft body 1, a key strip 4 is arranged on the outer surface of the shaft body 1, the key strip 4 is embedded on the outer surface of the shaft body 1, a U-shaped pipe 5 is arranged below the shaft body 1, an inflation inlet 6 is arranged on the U-shaped pipe 5, an air bag 7 is further arranged inside the shaft body 1, an air inlet 8 is arranged at one end of the air bag 7, an air outlet 3 is arranged at the other end of the air bag 7, a buckle 10 is arranged below the shaft body 1, a bearing 9 is arranged above the U-shaped pipe 5, and a valve is arranged at the position where the air outlet 3.

The principle of the utility model is as follows: the during operation, through pressing buckle 10 on the axis body 1, make in the 1 embedding U of axis body capable pipe 5, through aerifing inflation inlet 6, gas can reach inlet port 8 along U type pipe 5, enter into gasbag 7 through inlet port 8 in, gas entering gasbag 7 can make gasbag 7 inflation, gasbag 7 after the inflation can jack-up inlay in the key strip 4 of 1 surface of axis body, thereby make 4 protruding axis body surfaces of key strip, when the work is ended, through pressing the valve on the gas release hole 3, thereby discharge the outside with the gas of 7 the inside of gasbag.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
