Description

Intake connector of air pump

The present invention relates to a gas inlet nozzle, and more particularly to an air pumping device for communicating an air inlet nozzle mounted to an air inlet nozzle.

With the prosperity of healthy and leisure, more and more people regard riding bicycles as a kind of fitness or leisure activities. In order to cope with sudden situations during riding, such as puncture, etc., they are usually prepared with the car. Air pumping device. Since the specifications of the tire inlet nozzle can be roughly divided into the US inlet nozzle and the long-length regulation nozzle, in order to make the pumping device available for both sizes of the nozzle, the manufacturer is usually in the United States. An additional detachable extension joint is attached to the air inlet connector for the user to disassemble and select, and some users will install another type of adapter on the US or regulated air inlet nozzle. In order to be able to correspond to the specification of the air inlet connector of the air pumping device, it is quite inconvenient in either of the above methods, and it is easy to cause the adapter to be attached or the extension joint to be lost.

Accordingly, it is an object of the present invention to provide an air intake nozzle for an air intake device of an air intake nozzle that is simultaneously applicable to US regulations and regulations.

Therefore, the air inlet connector of the new air pumping device is used to connect The air inlet is installed in one air pipe, and can be installed in any one of the US regulations and regulations. The air inlet has a thimble, and the air inlet connector includes: a connector assembly, and is respectively mounted on the connector One of the components is a hollow tubular push rod, an elastic return member and a positioning adjuster. The joint assembly includes a hollow tubular joint member for screwing the air inlet, and a pivotally coaxially pivotable end portion of the joint member for communicating with the hollow tubular tube of the air tube The connecting member, and the connecting member cooperates with the connecting member to define an installation space that extends up and down. The jacking column is coaxially disposed in the installation space coaxially up and down, and can push the first position of the ejector of the inlet nozzle of the US standard in a conventional manner, and is subject to the regulation The gas nozzle moves up and changes relative to the second position of the ejector pin of the inlet of the regulation. The resetting member is installed in the installation space, and elastically pushes the jacking column downwardly in the direction of the first position. The positioning adjuster is mounted outside the joint assembly and can be driven into the installation space to position the push column in the first position.

The function of the new model: through the structural design of the joint assembly, the push-pull column, the resetting member and the positioning adjuster, the novel air inlet nozzle joint can be applied to both the US standard and the regulation two kinds of air inlet nozzles, and the utility model does not need to be disassembled when used. With replacement parts or adapters, users don't have to worry about preparing different sizes of air inlet adapter parts, which is quite convenient and practical.

The restoring member 5 is a spring, and the bottom end portion thereof is sleeved outside the top end portion of the pushing tube portion 41, and is pressed against the top surface of the blocking portion 42 to the lower limit position, and the top end is elastically offset by the top end thereof. The connecting member 32 is elastically pushed up and down in the direction of the first position.

The positioning adjuster 6 is fixedly mounted on the outer peripheral surface of the small diameter section 312 of the joint member 31, and can protrude radially into the joint member 31, and The jacking post 4 is positioned in the first position. The positioning adjuster 6 includes a fixing ring seat 61 that is fixedly mounted on the outer circumferential surface of the joint member 31 and communicates with the positioning screw hole 313, and is axially displaceably disposed in the fixing ring seat 61. The positioning pin 62 is screwed into the positioning screw hole 313, and the positioning bolt 62 is fitted with a hermetic gasket 63 for airtightly contacting the inner circumferential surface of the fixing ring seat 61. . The positioning pin 62 can be radially moved into the mounting space 30 with respect to the joint member 31, and the inserting card is positioned in the positioning groove 421 of the pushing rod 4, so that the pushing rod 4 is positioned at the first a location.

Referring to Figures 2 and 3, when the air inlet connector of the air pumping device is used, the air inlet connector 800 can be adjusted according to the specifications of the air inlet nozzle 800 of the tire or article that is scheduled to be pumped. If the inlet nozzle 800 is a US standard, the positioning pin 62 of the positioning adjuster 6 needs to be adjusted to protrude into the installation space 30, and the pushing column 4 is positioned at the first position, and then The connector member 31 is screwed out of the air inlet 800 of the US standard, so that the top end of the US air inlet 800 is airtightly pressed against the washer 34. At this time, the pushing column 4 is relatively opposite. The ejector pin 801 is pushed down to open the inlet nozzle 800 of the US gauge for use in pumping.

Referring to Figures 2 and 4, when the compliant inlet nozzle 800 is used, the locating pin 62 is screwed away from the ejector post 4 so that the ejector post 4 can be axially displaced. Then, the joint member 31 is screwed to the outside of the air inlet 800 of the regulation. Since the length of the air inlet 800 of the regulation is long, the air inlet 800 of the regulation protrudes upward through the joint member. The airtight washer 34 at the bottom end portion of the 31, and the screw lock is fixed to the large screw hole portion 315 and the small screw hole portion 316 of the screw lock portion 314, thereby pushing the pusher column 4 upward to the second position. this When the push-pull column 4 is pushed down by the reset elastic force generated by the elastic compression of the resetting member 5, the push-pull column 4 is pushed downward relative to the ejector pin 801 of the air inlet 800 of the regulation, so that the regulation The air inlet 800 is opened to allow airing.

When the joint member 31 is detached from the inlet nozzle 800 of the regulation, the restoring elastic force of the reset member 5 pushes the push-up column 4 downward to the first position against the second shoulder portion 318. position.
