Short head type US law nozzle universal joint

This creation is related to the gas nozzle joint, and more specifically refers to a short-headed US-style gas nozzle universal joint.

According to the bicycle tires, there are many types of air nozzles, which are mainly divided into American air nozzles and French air nozzles.

For different types of nozzles, the conventional inflation joints cannot be used universally, so they must be replaced when used, and there is inconvenience in replacement. At present, many manufacturers have developed inflatable joints for universal American and French air nozzles. The main purpose is to design a movable ejector inside to inflate the French air nozzle when the ejector pin is pushed in, while the ejector pin is When extrapolated, the American nozzle can be inflated.

However, as disclosed in Chinese Patent Publication No. 423612, it is mainly provided with a cam seat, a top body and a thimble coupled to the top body in a head portion, the cam seat having a long outer diameter and a a short outer diameter, when the cam seat is rotated, and the long outer diameter is pressed against the top body, the thimble is pushed outward to inflate the American air nozzle, or rotate the cam seat, and the short When the diameter is against the top body, the thimble can be retracted and the French nozzle can be inflated. However, in this design, since the top body and the ejector are movable outside the cam seat (ie, the top body and the thimble are positioned outside the rotation axis of the cam seat), the head must be designed. Sufficient length to accommodate the length of the top body and the thimble itself plus the distance of the movement, resulting in a problem of excessive length of the head, which makes it relatively inconvenient to carry and use.

In view of this, in order to improve the prior art, the conventional joint of the US-style gas nozzle has a problem that the head is too long, causing inconvenience in carrying and use; therefore, the creation provides a short-headed American-style nozzle. The universal joint comprises: a head having a chamber extending inwardly from one end of the head; a side of the head extending inwardly with a perforation communicating with the chamber; a rotating column, the rotating column is placed The inside of the head chamber can be rotated by the external force, and the inside of the rotating column has a hollow chamber. The outer surface of the rotating column is radially opened with an opening, and the opening communicates with the hollow chamber. The column has a pressing portion at one end adjacent to the opening, the rotating column has an air guiding hole at one end thereof, and the air guiding hole communicates with the hollow chamber, and the rotating column can be rotated by an external force to an inactive position to an active position; An injection part is inserted into the cavity of the rotating column from the perforation of the head, and a receiving hole extends from one end of the pressing piece, and the outside of the pressing part has a function of connecting the receiving hole. Hole; an compression ring, elastic, In the perforation of the head; a thimble unit is placed in the receiving hole of the pressure injection member, and can be displaced by an external force between an American position and a French position; thereby achieving effective reduction of the volume, Improve the convenience of carrying and using.

Therefore, the above is a short head type provided by the first preferred embodiment of the present invention. The introduction of the various components of the US-style gas nozzle universal joint 100 and the assembly method thereof, and then the characteristics of its use are described as follows: When inflating an American air nozzle 91 by the present creation, please refer to the third to sixth figures, First, the rotating column 20 is rotated to the inactive position by rotating the cylinder 61 of the inflating cylinder 60, so that the ejector pin 51 is pushed by the elastic force of the ejector pin 52 to be pushed to the American position (such as the fourth As shown, the American air nozzle 91 is inserted through the through hole 112 of the head 10 and passes through the compression ring 40 to abut the thimble 51 (as shown in the fourth figure). Then, the rotating column 20 is rotated to the active position by rotating the cylinder 61 of the inflatable cylinder 60, so that the rotating column 20 is rotated from the inactive position to the active position (as shown in FIG. 5). The rib 231 of the pressing portion 231 of the rotating column 20 penetrates into the working hole 32 of the pressing member 30 and is blocked against the end edge of the ejector pin 51 (as shown in FIG. 6) to prevent the The thimble 21 is retracted (ie, the thimble is restricted to be in the U.S. position), and the nip 231 is displaced by the hem 231, so that the nip 30 interlocks the compression ring 40, and the compression ring 40 is deformed and tightened. The American air nozzle 91 is inflated on the American air nozzle 91.

When the French air nozzle 92 is to be inflated by the present invention, please refer to the seventh to ninth drawings. First, the rotating column 20 is rotated to the inactive position by rotating the cylinder 61 of the inflatable cylinder 60, and then The French air nozzle 91 is inserted through the through hole 112 of the head 10 and passes through the compression ring 40 to push the ejector pin 51 to the French position (as shown in the seventh figure). Then, by rotating the cylinder 61 of the inflatable cylinder 60, the rotating column 20 is rotated to the active position, so that the rotating column 20 is rotated from the inactive position to the active position (as shown in FIG. 8). The rib 231 of the rotating column 20 penetrates into the working hole 32 of the pressure injecting member 30, so that the French air nozzle 92 is located between the two ribs 231 (as shown in FIG. 9), and then the pressure Side 23 1 The pressing member 30 is displaced, and the pressing member 30 is interlocked with the pressing ring 40, so that the pressing ring 40 is deformed and tightened to the French air nozzle 91 to inflate the French air nozzle 91.

Therefore, since the thimble of the present creation can be moved into the cavity of the rotating column, the length of the thimble can be greatly reduced, thereby effectively reducing the overall volume, so as to facilitate carrying and use. Sex.

In addition, as shown in the tenth and eleventh drawings, a short-head type US-style nozzle universal joint 200 according to the second preferred embodiment of the present invention includes a head 10 as in the first preferred embodiment. a rotating column 20, a pressure injection member 30, a compression ring 30, and a thimble unit 40, but the main difference is that in the present embodiment, the inflatable tube of the first embodiment is changed into a joint 70, the joint 70 is screwed to the rotating column 20.
