Obviously, the described embodiments are only some of the embodiments of the present invention, and not all of the embodiments.Embodiment 1A tire quick inflation tank, as shown in Figs. 1-3, comprises a tank body 1, a sealing flange 2, a mounting platform 3, a pressure relief valve 51 and a sealing piston 22, the sealing flange 2 being fixedly connected to a tank mouth of the tank body 1; the mounting platform 3 being accommodated inside the tank body 1 and fixedly connected to the sealing flange 2; a cavity is provided inside the mounting platform 3; the sealing piston 33 is accommodated in the cavity and a first PEEK sealing ring is fixedly arranged at an end of the sealing piston 33 facing the sealing flange 2; a second PEEK sealing ring is arranged at the other end of the sealing piston 33 and the other end of the sealing piston and the cavity form a sealing cavity 37; a compression spring 34 is accommodated in the seal cavity 37 and one end of the compression spring 34 is abutted against the seal piston and the other end of the compression spring 34 is abutted against the mounting platform 3; at least one piston vent hole 331 is also provided on the seal piston 33; the seal chamber 37 is connected to the inside of the tank body 1 through the piston vent hole 331; a first air supply hole 31 is formed on the side wall of an end of the mounting platform 3 facing the seal flange 2; a second air supply hole 32 is formed on the other end of the mounting platform 3; and the pressure relief valve 51 communicates with the seal chamber 37 through the second air supply hole 32; a third air supply hole 21 is formed on the seal flange 2; an end of the sealing piston is abutted to the sealing flange 2 and covered at the third air supply hole 21 to form a sealing structure.According to the present invention, when the sealing piston 33 moves up and down within the air pressure sealing chamber 37, good temperature adaptability can be obtained by the cooperation of the first PEEK seal ring and the second PEEK seal ring when being sealed by the first PEEK seal ring and the second PEEK seal ring made of PEEK material, and the degree of deformation is small. This prevents the inner seal of the seal piston 33 and the air pressure seal chamber 37 from being poor in sealing due to temperature changes during up and down movement. At high temperatures, it can be prevented that the first PEEK sealing ring and the second PEEK sealing ring are connected too firmly to the inner wall of the air pressure sealing chamber 37 due to the thermal expansion and impair the sliding of the sealing piston 33.Moreover, the sealing piston is provided with a first boundary groove and a second boundary groove; the first PEEK sealing ring is accommodated within the first boundary groove; the second PEEK sealing ring is accommodated within the second boundary groove; the first PEEK sealing ring is also provided with a chamfered surface 334 that can contact the sealing flange 2; the piston ventilation hole 331 is located between the first PEEK sealing ring and the second PEEK sealing ring.According to the present invention, when the sealing piston 33 moves up and down within the air pressure sealing chamber 37, good temperature adaptability can be obtained by the cooperation of the first PEEK seal ring 332 and the second PEEK seal ring 333 in sealing by the first PEEK seal ring 332 and the second PEEK seal ring 333 made of PEEK material, and the degree of deformation is small. This prevents the inner seal of the seal piston 33 and the air pressure seal chamber 37 from being poor in sealing due to temperature changes during up and down movement. At high temperatures, it can be prevented that the first PEEK seal ring 332 and the second PEEK seal ring 333 are excessively firmly bonded to the inner wall of the air pressure seal chamber 37 due to thermal expansion and impair the sliding of the sealing piston 33. The chamfered surface 334 on the first PEEK seal ring 332 may increase the contact area of the seal part and also fully utilize deformation of the seal ring to improve the sealing effect.Moreover, it further comprises an air supply gun barrel 9; the air supply gun barrel 9 is detachably connected to the seal flange 2; the air supply gun barrel 9 passes through the third air supply hole 21 and the first air supply hole 31 one after another and communicates with the inside of the tank body 1.Moreover, it further comprises four first bolts and six second bolts; four first bolt holes 22 are provided on the sealing flange 2; four fastening posts 35 are fixedly provided on the outer wall of the fastening platform 3, and the inside of the four fastening posts 35 is each provided with a first through hole 36 that can correspond to the four first bolt holes 22 in a one-to-one correspondence; four bolts pass through the four first through holes 36 in a one-to-one correspondence and are screwed to the four bolt holes; six second bolt holes 11 are provided on the rim of the tank mouth of the tank body 1; six second through holes 23 are provided on the sealing flange 2; six second bolts pass through six second through holes 23 in a one-to-one correspondence and are then screwed to six second bolt holes 11.Moreover, it further comprises a manometer 7; the manometer 7 is fixedly connected to the sealing flange 2; a fourth air supply hole 24 is also provided on the sealing flange 2; the inlet end of the manometer 7 passes through the fourth air supply hole 24 and communicates with the interior of the tank body 1.Moreover, it further comprises an inflation valve 8, wherein the inflation valve 8 is fixedly connected to the seal flange 2; a fifth air supply hole 25 is further provided on the seal flange 2, the output end of the inflation valve 8 passes through the fifth air supply hole 25 and communicates with the inside of the tank body 1.Embodiment 2Moreover, as shown in FIGS. 7-11, this application provides another embodiment, an inflation tank, comprising: a first handle 12 and a valve structure for a tire quick inflation tank as described in Embodiment 1, wherein the first handle 12 is fixedly connected to the outer wall of the tank body 1; wherein the pressure relief valve 51 is fixedly connected to the first handle 12; wherein a first air pump switch 53 for controlling a pressure relief valve 51 is further provided on the first handle 12.Moreover, on a lower end facing position of the outer surface of the air supply barrel 9, four outer barrel arc grooves 91 are provided, four flange inner grooves 26 are provided on the inner surface of the seal flange, and an extrusion spring 27 is movably disposed in the flange inner groove 26, respectively, a limiting arc buckle 28 is movably disposed in the flange inner groove 26, respectively, and the limiting arc buckle 28 is movably locked to the inside of the outer barrel arc groove 91, and the upper surface of the limiting arc buckle 8 is respectively provided with an arc groove.When the apparatus is used for inflating various tires, the cooperation of the air supply gun barrel 9 and the limiting arch buckle 28 frequently requires replacing the air supply gun barrel 9 with air outlets of different shapes. At this time, the air supply gun barrel 9 may be first rotated forty-five degrees so that both side surfaces of the limiting arc buckle 28 are in contact with the surface of the outer gun barrel arc groove 91 so that the limiting arc buckle 28 is retracted inside the flange inner groove 26. Then, the air supply gun barrel 9 can be pulled out directly, and then another air supply gun barrel 9 having another shape can be inserted into the inside of the movable flange. Then, the air supply gun barrel 9 is rotated so that the restriction arc buckle 28 is ejected by the elastic potential energy of the extrusion spring 27 and is seated in the outer gun barrel arc groove 91, thereby fixing the air supply gun barrel 9. This prevents the air supply gun barrel 9 from dropping, thereby making it convenient for the apparatus to replace and service the air supply gun barrel 9.Embodiment 3Moreover, as illustrated in FIGS. 4-6, this application provides another embodiment, an inflation tank, including: a fixed cover 4, a second handle 5, a third handle 13, and a valve structure for a tire quick inflation tank as described in Embodiment 1. The third handle 3 is fixedly connected to the outer wall of the tank body 1, the fixed cover 4 is fixedly connected to the seal flange 2; both ends of the second handle 5 are fixedly connected to the fixed cover 4; the second handle 5 houses an air supply pipe 52; the pressure relief valve 51 is disposed in the second handle 5; the pressure relief valve 51 passes through the air supply pipe 52 and the second air supply hole 32 in sequence and communicates with the seal chamber 37; a second air pump switch 53 for controlling a pressure relief valve 51 is provided on the second handle 5.In this embodiment, the air supply gun barrel 9 is threadedly connected to the seal flange 2.In this application, in particular, in order to improve the stability of the inflation tank and avoid unstable holding, this embodiment provides a quick inflation tank which can be held stably, particularly comprising a tank body 1. a sealing flange 2 is fixedly provided at the mouth of the tank body 1, and a fixed cover 4 is also fixedly provided at the mouth of the tank body 1; the second handle 5 is fixed to the fixed cover 4 and the third handle 13 is fixed to the side wall of the tank body 1. During actual use, the user holds the second handle 5 with one hand and the third handle 13 with the other hand. The two hands cooperate to improve the control capability of the inflation tank and reduce the impact of the rebound of the inflation tank. As compared with the inflation tank in the related art, the stability of the utilization process can be further improved.Check first with the manometer 7 whether the pressure in the tank body 1 is adequate. When the pressure in the tank body 1 is too high, the tank body 1 needs to be inflated via the inflation valve 8 so that the pressure in the tank body 1 is within a preset pressure range. Then, lift the inflation tank, hold the second handle with one hand and the third handle with one hand. Align the inflation tank in the gap between tire and wheel hub and press the air pump switch 53 on the side of the second handle with the thumb. The air pump switch 53 actuates the pressure relief valve 51 to introduce the high pressure gas into the seal chamber 37 and discharge it quickly via the air pipe 52. The pressure in the seal chamber 37 rapidly decreases and the high pressure in the tank body 1 overcomes the elastic force of the spring and rapidly lowers the sealing piston. After the sealing piston is pressed down, the third air supply hole 21 is not blocked on the sealing flange 2. After the third air supply hole 21 and the second air supply hole 32 are connected to each other, the high pressure in the tank body 1 is ejected from the mouth through the air supply gun barrel 9 and flows into the inside of the tire, and completes inflation of the tire. When the air pump switch 53 is stopped from being operated, the pressure relief valve 51 is closed. At this time, the gas in the seal chamber 37 no longer escapes, and the high-pressure air in the tank body 1 returns to a pressure-balanced state through the piston vent hole 331 on the seal piston. Therefore, there is no pressure difference between the seal chamber 37 and the tank body 1, and the seal piston will again block the third air supply hole 21 of the seal flange 2 under the elastic force of the spring, thereby closing the inflation tank.The present invention is not limited to the above-described embodiments, if various changes or modifications of the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the scope of the claims and the corresponding technical scope, the present invention is intended to include these changes and modifications as well.List of reference numerals1 Tank body 11 Second screw hole 12 First handle; 13 Third handle 2 Sealing flange 21 Third air supply hole 22 First screw hole 23 Second through hole 24 Fourth air supply hole 25 Fifth air supply hole 26 Flange inner groove 27 Extrusion spring 28 Limiting arc buckle 3 Fastening platform 31 First air supply hole 32 Second air supply hole 33 Sealing piston 331 Piston ventilation hole 332 First PEEK seal ring 333 Second PEEK seal ring 334 Chamfered surface; 335 Piston bottom groove; 336 Cushion pad 34 Compression spring 35 Fastening post 36 First through hole; 37 Sealing chamber 4 Fixed cover 5 Second handle 51 Pressure relief valve 52 Air pipe 53 Air pump switch 7 Manometer 8 Inflation valve 9 Air supply gun barrel 91 Outer gun barrel arc groove.References included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
