American inflatable joint

This creation is related to an inflatable joint, and more specifically to an American inflatable joint.

Press, between the inflatable device (such as the pump) and the nozzle of the tire, must be connected by an inflation joint to facilitate inflation.
However, the most common type of inflatable joints at present is mainly divided into two kinds of special American air nozzle joints and French air nozzle joints, and among them, American air nozzle joints are most common.
However, when the inflation joint is tightly engaged with the American air nozzle, it is often pressed and fixed by the lever of the lever, so the parts required for the inflation joint are too complicated, resulting in no market competitiveness in terms of manufacturing and selling price. . Moreover, limited by the spoke shape of the tire, the operating space that can be used between the inflation joint and the tire nozzle is already quite narrow, and it is more necessary for the inflation joint which is pressed and fixed (especially with a lever). The extra operating space causes the user to have a lot of inconvenience in operation.

In view of this, in order to improve the prior art, the conventional American inflatable joint has problems that the parts are too complicated, the manufacturing and the selling price are not competitive in the market, and the additional operation space is required, and the operation is inconvenient; The invention provides an American inflatable joint, which mainly comprises: a restricting cylinder having an axially extending receiving hole, wherein the receiving hole has a limiting hole having a non-circular cross section; and a front rotating drum having An axially extending working hole, the rear end of the front rotating sleeve is coaxially sleeved and coupled to the front end of the receiving hole of the limiting cylinder, and the front rotating sleeve is axially rotatable relative to the limiting cylinder, and the front end of the working hole has a The ventilating hole has a coupling hole which is axially penetrated, and the front end of the rear rotator is coaxially sleeved and coupled to the rear end of the accommodating hole of the limiting cylinder, and the rear rotator can be opposite to the The limiting cylinder performs a shaft rotation, the coupling hole has an internal thread; a nozzle column has an axially extending air hole, the mouth of the nozzle column has a mouth portion, the rear end has a pipe joint portion, and the middle portion has a pipe portion Restriction department The outer peripheral mask has a restricted circumferential surface and a male thread having a non-circular cross section, and the restricting portion is disposed in the receiving hole of the limiting cylinder, and the mouth is located in the working hole of the front rotating tube, the tube The connecting portion is located in the coupling hole of the rear drum, and the limiting peripheral surface is located in the limiting hole of the limiting cylinder, and the external thread is screwed with the internal thread of the rear rotating drum; thereby achieving a simple structure, manufacturing and selling price. Competitive, no additional operating space and convenient operation.

Therefore, the above description is a description of each component of the American inflatable joint 100 and its assembly manner provided by a preferred embodiment of the present invention, and then its use characteristics are as follows:
When the present invention is to be combined with an American air nozzle 99 (as shown in the fourth figure), the American air nozzle screw hole 211 of the drum 20 before the creation is first brought into contact with the American air nozzle 99 (as shown in the fifth figure). And being rotated by the user on the drum stop portion 23 before the front drum 20 to rotate the front drum 20 (as shown in the sixth figure), so that the external thread 991 on the American air nozzle 99 is The American nozzle screw hole 211 of the front drum 20 is screwed to abut against the nozzle leakage ring 40.
Then, the user rotates the rear drum 30 again, so that the internal thread 311 of the rear drum 30 and the external thread 57 of the nozzle post 50 are screwed together, so that the mouth portion 52 of the nozzle post 50 is turned toward The American nozzle screw hole 211 near the front drum 20 linearly moves axially until it is connected to the American air nozzle 99 (as shown in the seventh figure). At the same time, the restricting circumferential surface 56 of the nozzle post 50 and the restricting cylinder 10 restrict the holes 112 from being restricted by a non-circular cross section, so that the nozzle post 50 can be prevented from rotating synchronously with the rear drum 30. The nozzle post 50 is maintained in a continuous axial advancement.
In this way, gas can be injected into the American air nozzle 99 through the gas pipe 70 and the air hole 51 by the inflation device to complete the inflation operation. Since the external thread 99 of the American air nozzle 99 is screwed with the American air nozzle screw hole 211 of the front drum 20, it can ensure that the creation does not separate from the American air nozzle 99 during the inflation process. The smoothness of the inflating.
Furthermore, when the user rotates the rear drum 30 so that the mouth portion 52 of the nozzle post 50 moves linearly in the direction of the American nozzle screw hole 211 of the front drum 20, the sleeve is placed on the joint. The airtight ring 60 on the nozzle post 50 is positioned between the outer circumferential surface of the nozzle post 50 and the inner circumferential surface of the action hole 21 of the front reel 20 to form an airtight state, thereby ensuring the smoothness of inflation.
When the inflation operation is completed, the front drum 20 can be reversely rotated to separate the American air nozzle 99 from the original creation, and then the rear drum 30 is reversely rotated to connect the mouth portion 52 of the nozzle post 50. Move axially away from the direction of the American nozzle screw hole 211 to facilitate the next inflation operation.
Therefore, since the creation system rotates the drum with the American air nozzle in the same axial direction to fix the American air nozzle, it is quite intuitive in operation, and the mouth of the nozzle is connected to the American gas. The mouth is also realized by rotating the American and the air nozzle behind the coaxial tube, and no additional operation space is required, so that the user can operate in a small space to improve the operation convenience of the creation. Moreover, due to the simple structure of the creation, the manufacturing cost and the selling price can be simultaneously reduced, and the lightweight shape is also easy to carry, which is beneficial to the competitiveness in the market.
The above description is only for the preferred embodiment provided by the present invention, and is not intended to limit the scope of implementation of the present invention. All of the relevant artisans in the art are equally varied according to the present creation, and should belong to the present invention. The scope of coverage.
