Abstract

A device that facilitates the inspection and inflation of a spare wheel is a device that moves the receiver / deflector attached to the spare wheel to another receiver / deflate. To help inflate the wheels Reserve is more convenient. Can be used to inspect and inflate the wheels From general gas stations as well as inspecting and inflating working wheels Even car users will check and inflate themselves. Can be done conveniently When a spare wheel is needed, simply remove the auxiliary device. Ready to use immediately And when the spare wheel is already in use, then the head winder is connected With the receiver / wheel deflector, the auxiliary equipment is in the picture, ready to check and inflate

Claims (3)

1. The device facilitates the inspection and inflation of the spare wheel and consists of 3 parts: the air nozzle (made of hard or metal), the pipe and the air outlet. The air nozzle has four components, the first component is the guacre, it is a hollow cylindrical shape with a threaded inside diameter equal to the outer diameter of the receiver / deflector. No end The helix has a diameter slightly larger than the inside diameter of the mouth. And there are 4 holes for inserting the bolts. The second part of the air nozzle is a rubber ring with the same outer diameter as the inner diameter of the rear cover. And the inner diameter of the rubber ring is equal to the diameter Center outside the axis of the short side of the arrowhead. The long back has a thickness equal to or slightly greater than that of Axis height on the short side of the arrowhead. The third component of the air nozzle is Pressing the arrow head looks like a thick coin The outer diameter is the same as the inner diameter of the end cap, center with axes on both sides. The short head has a groove in the center of the axis, a hole smaller than the arrowhead of the receiver / deflector, with the hole running the entire length of the axis. The fourth component of the winder is a pin shaped like a metal wire. The U shape keeps the components of the air head fixed together. In order is Pressed rubber ring cover Arrowhead and engraved The thickness of the rubber ring and the thickness of the arrow pad. And the latch hole is in relation to each other, that is, when the air head is assembled and then connected to the receiver / deflate Will cause the air out of the wheel into and Out through the hole at the end of the arrow head. The air does not leak. Other areas mentioned are the characteristics of the air nozzle. The auxiliary device has a second component, a pipe, which is a metal pipe in the middle, assembled with a rubber tube. The inner diameter of the rubber tube must be smaller than the outer diameter of the axle at the end of the arrow head to secure the mounting. The other long hose must be attached to the end of the receiver / deflector so that when the air pressure is applied, the tire will not be loosened from the two devices. The last component of the auxiliary device is the receiver / deflector. It has characteristics and is the same type as the air intake / deflector attached to the wheel rim. The components of all 3 types of aids are put together in order: the air nozzle, the rubber pipe, the metal pipe, the long pipe and the receiver / discharge head. The wind aids are ready to be used. The behavior is to bring the auxiliary device in the side of the winder with internal threads. Put in the receiver / deflate the spare wheel with external thread. The arrow head presses to the arrow head, causing the wind from the spare wheel to be blocked by the rubber ring, causing the air to enter the groove. And a hole in the axis that presses the arrowhead and then goes to you in the rubber tube flows through the metal tube rubber tube But the wind cannot get out of the pipe. Because there is a head Receive / deflate off When the receiver / deflector is placed in a suitable position. Will keep the equipment ready for use 2.According to the claim in item 1, the air opener also has a different characteristic from item 1, which is the wind opener using the method of wearing with a tooth that is abrasive to prevent the air opener from slipping from the receiver / deflating. The air nozzle of this type has three components, the first is the head, the cover is cylindrical, the mouth has no internal thread. The inner center is equal to the outer diameter of the receiver / deflector. The end has a hole diameter circle. In equal to the outer diameter of the axis at the end of the arrowhead In the upper part of the head, there is a tooth that goes through the head. Acts as a scrub with the outer groove of the receiver / air release (press the bell, the teeth will not abrasive The second component is a long ring, the outer diameter is equal to the inner diameter of the crown. The mind diameter is equal to the line. Through the outer center of the axis that hit the arrowhead above. The third component is that the arrowhead is shaped. Same as the wind opening according to claim 1, but the diameter of the coin is the same thickness as the diameter. The middle of the inner circle of the inner cap Assembly of the pneumatic head as follows The cap is attached to the big tooth, and then downward, the arrowhead press and the ring are put down accordingly. The size of the head cover Rubber ring thickness and thickness The items that hit the arrowhead are related. That will cause when the head to open the air to the receiver / deflate will cause the air from the backup wheel to flow through and the hole at the bottom of the arrow head. Then cut the rubber tube, metal pipe, rubber pipe and have the air outlet head closed to prevent the air out as same as claim item 1 3.According to the claim 1 or 2, the wind opening also has other characteristics, that is, the wind opener with the head The cover and the arrow head are the same. There are two parts: the cover has a cylindrical shape. The mouth side has an internal thread, the same as the air nozzle according to claim 1. Just at the end, there is a presser on the arrowhead and the head. Homogeneous cover The second component is a rubber ring, the outer diameter equal to the diameter. The inner center of the head cover And the inner diameter of the rubber ring is equal to the outer diameter Of the axis that hit the arrowhead Connecting the auxiliary equipment is made in accordance with claim 1. Let the pipe rotate accordingly In addition, the crown may be reversed between the claims of 2 or 3, ie, the crown tooth will use a homogeneous hood with a hood and an arrow press. And head covers according to claim 3 above, style caps with different arrowheads and head covers may be used.
