Description

Technical Field

[0001] The invention relates to an air pump accessory, in particular to an air pump nozzle. Background Art

[0002] An air pump is a commonly used air pumping device. Whether it is an electric air pump or a manual air pump, it is provided with an air pump nozzle connected to the tire nozzle. Since the tire nozzles on the market are divided into French air nozzles and American air nozzles, the air pump nozzle structures are also different. For example, the rotary air nozzle disclosed in Publication No.: CN10544335913 and the rotary switching air nozzle head disclosed in Publication No.: CN10529931313, the above two air nozzles are common air nozzles in the industry. It can be known from the public literature that when using the above two air nozzles, the air pump nozzle is tightly sucked into the tire nozzle by flipping the lever or wrench up and down. Since the air pump is used in a wide range of car models, when used on a car, because the car wheel hub is larger, the air pump nozzle can be easily stuck on the tire nozzle, while the motorcycle wheel hub is narrower, and due to the installation of the brake caliper, when inflating the motorcycle wheel, the air pump nozzle The tire valve is very inconvenient to move up and down, and some motorcycle models cannot turn the lever piece horizontally, which makes it impossible to lock the tire valve. When inflating such tires, the tire valve can only be manually turned outward to lock the pump nozzle on the outside of the tire. The tire needs to be inflated frequently, and frequently turning the tire valve like this can easily shorten the service life of the tire valve and is also inconvenient to use. At the same time, in order to be compatible with both Presta valves and Schrader valves, the existing pump nozzles basically have both Presta valve heads and Schrader valve heads on the pump nozzle housing, which makes the pump nozzle housing too large, making it even more inconvenient to use. Summary of the Invention

[0003] In view of the defects of the existing air pump nozzles, the technical problem to be solved by the present invention is to provide an air pump nozzle that is more applicable and convenient for use with small-diameter wheels.

[0004] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, the present invention is realized through the following technical measures: an air pump nozzle, comprising: an air nozzle housing, a conversion air nozzle, a screw cap and a wrench, an air passage is provided in the air nozzle housing, the air passage is composed of a horizontal channel and a vertical channel, a partition is provided in the horizontal channel, the partition forms a left channel and a right plug interface in the horizontal channel, the vertical channel is connected to the left channel, and the vertical channel is used to fix the air pump ventilation hose, the conversion air nozzle is provided in the left channel, and is limited by the screw cap and the air nozzle housing.

[0005] A plug-in tube extends to the right side of the conversion gas nozzle, the end of which passes through the partition to the right plug-in interface, and one end of the wrench is plugged into the right plug-in interface and fixed to the plug-in tube;

[0006] A wedge is provided at the right end of the conversion air nozzle, and a wedge I is provided on the left side of the partition that can cooperate with the wedge, and the wedge and wedge I are abutted against each other and the conversion air nozzle is rotated by the rotation of the wrench or / and the plug-in end of the wrench is threadedly connected to the right plug-in interface, and the conversion air nozzle can be sucked tightly by rotating the wrench.

[0007] The air nozzle of the air pump is used to loosen or tighten the tire air nozzle by turning a wrench, which does not lengthen the air nozzle of the air pump laterally, is convenient for use with various types of tires, and does not require turning the tire air nozzle, thereby increasing its service life.

[0008] Furthermore, there are two wedge blocks and two wedge blocks I, and both are arranged at 180 degrees.

[0009] Furthermore, the wedge block and wedge block I are both composed of an oblique block and a horizontal block.

[0010] Furthermore, the wrench and the plug-in tube are fixed by screws.

[0011] Furthermore, the conversion gas nozzle includes:

[0012] The rotating seat is tightly inserted into the left channel. The left opening of the rotating seat is hollow inside to form an air outlet. An air hole connected to the air outlet is provided on the outer wall of the rotating seat. A plug-in tube is provided at the right end of the rotating seat.

[0013] A base, wherein a center hole is provided at the center of the base, and one end of the base abuts against the open end of the rotating base;

[0014] A push rod, one end of which is a push head, and a spring passing through the base is provided between the other end and the bottom of the air outlet hole;

[0015] A rubber air nozzle has a center hole in the center of the rubber air nozzle, and a fixing column with a diameter smaller than the rubber air nozzle extends to the right from the right end of the rubber air nozzle. The fixing column is inserted into the left side of the center hole of the base and rests against the push rod so that the push head can be in the rubber air nozzle. The rubber air nozzle is used to suck the tire air nozzle tightly.

[0016] Furthermore, a limit block is provided on the wrench, and two spaced-apart retaining blocks are provided on the inner wall of the right plug-in interface. The limit block cooperates with the two retaining blocks respectively, so that the wrench can be rotated and quickly positioned.

[0017] Furthermore, a sealing ring clamping ring is provided on the outside of the rotating seat, and a sealing ring is sleeved inside the clamping ring. The rotating seat at the air hole is also provided with a circular air duct with a diameter smaller than the outer diameter of the rotating seat, and the air hole is provided in the circular air duct.

[0018] Furthermore, a protrusion extends outward from the orifice of the air outlet of the rotating seat, and one end of the protrusion is provided with a 50-60 degree bevel angle. The right side of the push rod is provided with a 65-70 degree bevel angle I, which is opposite to the bevel angle. The above design is to make the push rod suitable for both American and French air nozzles. Because when inflating a French air nozzle, the French air nozzle will push the push rod into the rotating seat to avoid it, and the rotation of the rotating seat will drive the push rod to rotate. However, when inflating a Schrader air nozzle, the Schrader air nozzle cannot push the push rod into the rotating seat. At this time, the protrusion of the rotating seat needs to slide over the bevel angle I to push the push rod forward, so that the push rod can press against the Schrader air nozzle for inflation.

[0019] Furthermore, there are two protrusions, which are arranged at 180 degrees relative to each other, and the bevels on the two protrusions are not inclined on the same side. Two bevels I are provided on the right side of the push rod.

[0020] Furthermore, the angle of the bevel is 55 degrees, and the angle of the bevel I is 67 degrees.

[0021] Compared with the prior art, the advantages of the present invention are: better applicability for inflating tires of various sizes, more convenient use, more compact and reasonable overall structure, and no need to frequently turn the tire valve, which also increases the service life.

By rotating the wrench 4, the horizontal block of the above-mentioned wedge block 11 will pass the oblique block of the wedge block I12 and press against the horizontal block of the wedge block I12, so that the conversion air nozzle 2 can be moved to the left to tighten the tire air nozzle. Of course, the above-mentioned structure can also be composed of or increase another structure, which is: the above-mentioned wrench 4 and the above-mentioned right plug-in interface 9 are threadedly connected, so that the conversion air nozzle 2 can be moved to the left or reset after the wrench 4 is rotated through the threaded connection. As a preferred structure, a limiting block is fixed on the above-mentioned wrench 4, and two spaced-apart stop blocks are provided on the inner wall of the above-mentioned right plug-in interface 9. The limiting block cooperates with the two stop blocks respectively to make the wrench 4 rotate and quickly position.

[0033] Please refer to Figure 3 , the above-mentioned conversion air nozzle 2 is composed of a rotating seat 16, a base 18, a push rod 19 and a rubber air nozzle 22 from right to left. The above-mentioned rotating seat 16 is inserted into the left channel 8. The left side opening of the rotating seat 16 is hollow inside to form an air outlet. The outer wall of the rotating seat 16 is provided with an air hole 17 connected to the air outlet. The right end of the rotating seat 16 is provided with a plug-in tube 10. The center of the above-mentioned base 18 is provided with a center hole. The right end of the base 18 is against the open end of the rotating seat 16.

[0035] When in use, by turning the wrench counterclockwise, after the wrench is in place, the wrench drives the swivel seat to move to the left, driving the base and the rubber air nozzle to move to the left, so that the rubber air nozzle can suck the tire air nozzle tightly. After turning the wrench clockwise, the wrench drives the swivel seat to reset. At this time, the wedge block and wedge block Ⅰ are staggered instead of resisting each other like when the wrench is turned clockwise. In this way, the spring plus the rubber air nozzle resets the swivel seat to move right, and the rubber air nozzle can be separated from the tire air nozzle. At the same time, when inflating the Presta valve, the Presta valve will push the push rod into the swivel seat to avoid it, and the rotation of the swivel seat will drive the push rod to rotate. When inflating the Schrader valve, the Schrader valve cannot push the push rod into the swivel seat. At this time, the convex block of the swivel seat is required to slide over the bevel Ⅰ to push the push rod forward so that the push rod can push against the Schrader valve for inflating.
