Air valve structure of quick tire inflation tank and inflation tank

Abstract

According to the rapid tire inflation tank, through cooperation of the first PEEK sealing ring and the second PEEK sealing ring, when the sealing piston ascends and descends in the air pressure sealing cavity, through the first PEEK sealing ring and the second PEEK sealing ring which are made of PEEK materials, the rapid tire inflation tank has good temperature adaptability and is small in deformation quantity during sealing; therefore, poor sealing performance caused by temperature change of internal sealing of the sealing piston and the air pressure sealing cavity during lifting motion is prevented, and the situation that sliding of the sealing piston is affected due to the fact that the first PEEK sealing ring and the second PEEK sealing ring are excessively tightly connected with the inner wall of the containing cavity due to thermal expansion can be avoided when the temperature is high. The diagonal plane on the first PEEK sealing ring can increase the contact area of the sealing part, and the sealing effect can be improved by fully utilizing the deformation of the sealing ring.

[0002] Tires are circular, elastic rubber products that are mounted on various vehicles or machinery and roll on the ground. In actual assembly, due to the high hardness of the tire, the tire is usually deflated when it is installed on the rim.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] Example 1

[0037] like Figures 1-3 The illustrated tire quick-inflation canister includes: a canister body 1, a sealing flange 2, a fixing platform 3, a pressure relief valve 51, and a sealing piston 33; the sealing flange 2 is fixedly connected to the canister opening of the canister body 1; the fixing platform 3 is housed inside the canister body 1 and fixedly connected to the sealing flange 2; a cavity is formed inside the fixing platform 3; the sealing piston 33 is housed inside the cavity, and a first PEEK sealing ring is fixedly provided at one end of the sealing piston 33 near the sealing flange 2; a second PEEK sealing ring is provided at the other end of the sealing piston 33, and the other end of the piston forms a sealing cavity 37 with the cavity; a compression spring 34 is housed inside the sealing cavity 37. One end of the compression spring 34 abuts against the piston; the other end of the compression spring 34 abuts against the fixed platform 3; the sealing piston 33 is also provided with at least one piston vent hole 331; the sealing cavity 37 is connected to the interior of the tank body 1 through the piston vent hole 331; a first air supply hole 31 is provided on the side wall of the fixed platform 3 near the sealing flange 2, and a second air supply hole 32 is provided on the other end of the fixed platform 3; the pressure relief valve 51 is connected to the sealing cavity 37 through the second air supply hole 32; a third air supply hole 21 is provided on the sealing flange 2; one end of the piston abuts against the sealing flange 2 and covers the third air supply hole 21 to form a sealing structure.

[0038] This invention, through the cooperation of the upper and lower sealing rings, enables the sealing piston 33 to move up and down within the pneumatic sealing cavity 37. The upper and lower sealing rings, made of PEEK material, provide good temperature adaptability and minimal deformation during sealing. This prevents poor sealing between the sealing piston 33 and the interior of the pneumatic sealing cavity 37 due to temperature changes during the up-and-down movement. It also avoids an overly tight connection between the upper and lower sealing rings and the inner wall of the pneumatic sealing cavity 37, which could affect the sliding of the sealing piston 33.

[0039] Furthermore, the piston is provided with a first limiting groove and a second limiting groove; the first PEEK sealing ring is housed inside the first limiting groove; the second PEEK sealing ring is housed inside the second limiting groove; the first PEEK sealing ring is also provided with a chamfered surface 334 that can abut against the sealing flange 2; the piston vent 331 is located between the first PEEK sealing ring and the second PEEK sealing ring.

[0040] This invention, through the cooperation of the first PEEK sealing ring 332 and the second PEEK sealing ring 333, allows the sealing piston 33 to move up and down within the pneumatic sealing cavity 37. The first and second PEEK sealing rings 332 and 333, made of PEEK material, provide good temperature adaptability and minimal deformation during sealing. This prevents poor sealing between the sealing piston 33 and the interior of the pneumatic sealing cavity 37 due to temperature changes during the up-and-down movement. Furthermore, at higher temperatures, it avoids the first and second PEEK sealing rings 332 and 333 from becoming too tightly bonded to the cavity wall due to thermal expansion, which would affect the sliding of the sealing piston 33. The beveled surface 334 on the first PEEK sealing ring 332 increases the contact area of ​​the sealing part and fully utilizes the deformation of the sealing ring to improve the sealing effect.

[0041] Furthermore, it includes: a gas delivery gun 9; the gas delivery gun 9 is detachably connected to the sealing flange 2; the gas delivery gun 9 communicates with the interior of the tank body 1 after passing through the third gas delivery hole 21 and the first gas delivery hole 31 in sequence.

[0042] Furthermore, it also includes: four first bolts and six second bolts; four first screw holes 22 are provided on the sealing flange 2; four fixing posts 35 are fixedly installed on the outer side wall of the fixing platform 3; the interior of each of the four fixing posts 35 is provided with a first through hole 36 that corresponds one-to-one with the four first screw holes 22; the four bolts pass through the four first through holes 36 and are threadedly connected to the four screw holes; six second screw holes 11 are provided on the edge of the tank opening of the tank body 1; six second through holes 23 are provided on the sealing flange 2; the six second bolts pass through the six second through holes 23 and are threadedly connected to the six second screw holes 11.

[0043] Furthermore, it also includes: a pressure gauge 7; the pressure gauge 7 is fixedly connected to the sealing flange 2; the sealing flange 2 is also provided with a fourth air supply hole 24; the input end of the pressure gauge 7 communicates with the interior of the tank body 1 after passing through the fourth air supply hole 24.

[0044] Furthermore, it also includes: an inflation valve 8; the inflation valve 8 is fixedly connected to the sealing flange 2; the sealing flange 2 is also provided with a fifth air supply hole 25; the output end of the inflation valve 8 communicates with the interior of the tank body 1 after passing through the fifth air supply hole 25.

[0045] Example 2

[0046] Furthermore, such as Figures 7-11 As shown, this application provides another embodiment, an air inflator, including: a first handle 12 and an air valve structure of a tire quick inflator as described in Embodiment 1, wherein the first handle 12 is fixedly connected to the outer wall of the tank body 1; the pressure relief valve 51 is fixedly connected to the first handle 12; and a first air pump switch 53 for controlling the pressure relief valve 51 is also provided on the first handle 12.

[0047] Furthermore, the outer surface of the gas supply gun barrel 9 is provided with four barrel outer arc grooves 91 near the bottom end; the inner surface of the movable flange is provided with four flange inner grooves 26, each flange inner groove 26 is movably installed with a compression spring 27, each flange inner groove 26 is movably installed with a limiting arc buckle 28, each limiting arc buckle 28 is movably engaged into the barrel outer arc groove 91, and the top surface of each limiting arc buckle 28 is provided with an arc groove.

[0048] By cooperating with the air delivery gun barrel 9 and the limiting arc buckle 28, when the device is in use and different tires need to be inflated, it is often necessary to replace the air delivery gun barrel 9 with different shaped air outlets. At this time, the air delivery gun barrel 9 can be rotated forty-five degrees so that the two sides of the limiting arc buckle 28 contact the surface of the outer arc groove 91 of the gun barrel, thereby causing the limiting arc buckle 28 to retract into the inner groove 26 of the flange. Then, the air delivery gun barrel 9 can be pulled out directly, and then another air delivery gun barrel 9 of another shape can be inserted into the inside of the movable flange. Then, the air delivery gun barrel 9 is rotated so that the limiting arc buckle 28 is ejected by the elastic potential energy of the compression spring 27 and locks into the inside of the outer arc groove 91 of the gun barrel, thereby fixing the air delivery gun barrel 9 and preventing the air delivery gun barrel 9 from falling off, thus facilitating the replacement and maintenance of the air delivery gun barrel 9.

[0049] Example 3

[0050] Furthermore, such as Figures 4-6As shown, this application provides another embodiment of an inflatable canister, comprising: a fixed cover 4, a second handle 5, a third handle 13, and a valve structure for a tire quick-inflation canister as described in Embodiment 1. The third handle 13 is fixedly connected to the outer wall of the canister body 1; the fixed cover 4 is fixedly connected to the sealing flange 2; both ends of the second handle 5 are fixedly connected to the fixed cover 4; an air supply pipe 52 is housed inside the second handle 5; a pressure relief valve 51 is housed inside the second handle 5; the pressure relief valve 51 communicates with the sealing cavity 37 after passing through the air supply pipe 52 and the second air supply hole 32 in sequence; a second air pump switch 53 for controlling the pressure relief valve 51 is also provided on the second handle 5.

[0051] In this embodiment, the gas delivery gun tube 9 is threadedly connected to the sealing flange 2.

[0052] Specifically, in this application, to improve the stability of the inflatable canister and avoid unstable grip, this embodiment provides a fast-inflating canister that can be held stably. It includes a canister body 1, a sealing flange 2 fixedly installed at the canister opening, and a fixed cover 4 fixedly installed on the canister opening. A second handle 5 is fixedly installed on the fixed cover 4, and a third handle 13 is fixedly installed on the side wall of the canister body 1. In actual use, the user holds the second handle 5 with one hand and the third handle 13 with the other, coordinating the two hands to improve control over the inflatable canister and reduce the impact of recoil. Compared to inflatable canisters in the prior art, this further improves the stability during use.

[0053] First, use pressure gauge 7 to check if the pressure in tank 1 is appropriate. If the pressure in tank 1 is too high, it is necessary to inflate tank 1 through inflation valve 8 to bring the pressure in tank 1 to the preset pressure range. Then, lift the inflation canister, hold the second handle with one hand and the third handle with the other. Align the inflation canister with the gap between the tire and the rim, and press the air pump switch 53 on the side of the second handle with your thumb. The air pump switch 53 drives the pressure relief valve 51 to conduct the high-pressure gas in the sealed cavity 37 through the air supply pipe 52 for rapid release. The pressure in the sealed cavity 37 drops rapidly, and the high pressure in tank 1 overcomes the spring force to quickly press the piston down. After the piston is pressed down, it will not block the third air supply hole 21 on the sealing flange 2. After the third air supply hole 21 and the second air supply hole 32 are connected, the high pressure in tank 1 will be ejected from the nozzle through the air supply gun 9 and rush into the interior of the tire to inflate it. When people stop pressing the air pump switch 53 and the pressure relief valve 51 is closed, the gas in the sealing cavity 37 no longer leaks. The high-pressure air in the tank 1 will return to the pressure balance state through the piston vent 331 on the piston. Therefore, there is no pressure difference between the sealing cavity 37 and the tank 1. The piston will then block the third air outlet 21 of the sealing flange 2 again under the elastic force of the spring, thereby closing the filling tank.

[0054] This invention is not limited to the above-described embodiments. If any modifications or variations to this invention do not depart from the spirit and scope of this invention, and if such modifications and variations fall within the scope of the claims and equivalent technologies of this invention, then this invention also intends to include such modifications and variations.
