An inflatable shaft driving positioning clamp 100 with an inflator provided by the embodiment mainly includes a driving shaft 10, a fixing base 20, a movable seat 30, a limiting block 40 and a valve device 50, wherein: please refer to FIG. 1 to FIG. 3, the driving shaft 10, the rear end and a power source (not shown) is coupled to be driven by the power source to perform the in-situ shaft rotation. The front end of the drive shaft 10 is recessed with a receiving groove 11 for receiving one end of an inflation shaft 90. The drive shaft 10 is One side has a notch 12 communicating with the receiving groove 11 for the air-expansion shaft 90 to be disengaged. The inside of the driving shaft 10 has an inflation flow passage 13 for gas circulation.

Referring to Figures 1 to 3, the mounting base 20 is guided by the drive shaft 10 through its axis.

Referring to FIGS. 1 to 3, the movable seat 30 is driven by the drive shaft 10 to pass through its axis and is subjected to external force to slide along the drive shaft 10 toward the front end or the rear end.

Referring to FIGS. 1 to 3, the limiting block 40 is locked at a position near the axis of the movable seat 30. When the movable seat 30 slides toward the rear end of the driving shaft 10, the limit is limited. The block 40 closes the notch 12 to prevent the inflation shaft 90 from coming out radially. When the movable seat 30 slides toward the front end of the drive shaft 10, the limiting block 40 opens the notch 12 for The inflation shaft 90 is taken out of the receiving groove 11 .

Referring to FIG. 1 to FIG. 3 and FIG. 6 , the air valve device 50 is disposed in the inflation flow passage 13 of the drive shaft 10 and communicates with the receiving groove 11 for receiving the tolerance. The inflation shaft 90 in the slot 11 is inflated. The gas valve device 50 has a front connecting pipe 51, a rear connecting pipe 52, a double connecting pipe 53, a push rod 54, and a front spring. 55, a rear spring 56 and a rear joint 57; the front end of the front connecting tube 51 is recessed with a nozzle opening 511, and the rear end is recessed with a receiving hole 512, the inside of the front connecting tube 51 has a communicating mouth of the nozzle The opening 513 of the 511 and the receiving hole 512, and the aperture of the connecting hole 513 is smaller than the aperture of the nozzle opening 511 and the receiving hole 512. The inside of the connecting tube 52 has an introduction hole 521, and the double tube 53 is screwed between the rear end of the front connecting pipe 51 and the front end of the rear connecting pipe 52, and the inside of the double connecting pipe 53 has a constant hole 531, and the through hole 531 communicates with the receiving hole 512 and the introducing hole 521, The push rod 54 is disposed in the receiving hole 512 of the front connecting tube 51. The push rod 54 defines a tapered portion 541, a blocking portion 542 and a body portion 543 along the axial direction thereof. The front spring 55 is sleeved The body 543 of the rear push rod 54 abuts against the blocking portion 542 at one end thereof, and the other end abuts against the double connecting tube 53. The rear spring 56 is sleeved on the rear connecting tube 52, and One end abuts against the inner wall of the drive shaft 10, and the other end abuts against the rear connecting tube 52. The rear joint 57 is placed on the inflation flow passage 13 of the drive shaft 10. Medium and located at the rear end of the rear connector 52 for introducing the gas to the person. In the implementation, the inner peripheral edge of the nozzle joint 511 and the outer surface of the rear connecting tube 52 and the rear joint 57 are preset, and an O-ring is further respectively provided to provide the airtight effect of the relevant member.

Therefore, the above is a description of each component of the inflatable shaft driving positioning clamp 100 with an inflator and an assembly method thereof according to a preferred embodiment of the present invention, and then the characteristics of the use thereof are as follows: When the inflatable shaft 90 is combined with the present invention, the movable seat 30 is first slid to the rear end, so that the notch 12 of the drive shaft 10 is exposed, and the inflatable shaft 90 is placed through the gap 12 to be placed therein. In slot 11 (as shown in Figures 1 and 4).

Then, the movable seat 30 can be further moved to the front end to make the limit The block 40 closes the notch 12 to prevent the inflation shaft 90 from coming out radially, and at this time, the air nozzle 91 of the inflation shaft 90 is pushed against the push rod 54 of the valve device 50 (eg, 5th) As shown in the figure, the tapered portion 541 of the push rod 54 is pushed away from the communication hole 513, so that the inflated gas can enter the introduction hole 521 and the double of the rear connecting tube 52 via the rear joint 57. The through hole 531 of the connecting pipe 53 and the receiving hole 512 of the front connecting pipe 51 are introduced into the inflation shaft 90 via the communicating hole 513 through the air nozzle 91 of the inflation shaft 90 (as shown in FIG. 6). The effect of automatically inflating the inflation shaft 90 is to achieve a more convenient operation and operation.

When the inflatable shaft 90 is to be taken away, the movable seat 30 can be slid to the rear end, and the notch 12 of the drive shaft 10 can be opened to take the inflation shaft 10 away. At this time, the push rod 54 of the valve device 50 is slid by the elastic force of the front spring 55, so that the tapered portion 541 is abutted in the communication hole 513 (as shown in FIG. 7) to prevent gas leakage. The rear connecting pipe 52 is subjected to the elastic force of the rear spring 56, and the rear connecting pipe 52, the double connecting pipe 53, and the front connecting pipe 51 are displaced to the rear end, and the rear connecting pipe 52 is in contact with the rear joint 57 (such as 4 is shown), and the valve device 50 can be retracted when the valve device 50 is not required to be used to reduce the damage caused by the impact of an external force. When inflated, the inflated gas will drive the rear connecting tube 52 to compress the rear spring 56, and the rear connecting tube 52, the double connecting tube 53 and the front connecting tube 51 are extended forward (as shown in FIG. 5) to Inflated work.

In addition, a connecting key 14 is further disposed in the receiving groove 11 of the driving shaft 10 for coupling with the inflation shaft 90 to drive the inflation shaft 90 to synchronize the rotation.

The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all of the related art in the art according to the present invention are equivalent to the present invention. The scope of coverage.
