Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle-mounted air inflator technology, and in particular to a vehicle-mounted air inflator. Background Technology
[0002] Air inflators are control components in the industrial product field. Their main function is to regulate gas flow and control pressure. They are widely used in aerospace, marine engineering, vacuum equipment and other fields. Studies have shown that the sealing performance of air inflators directly affects the operating efficiency of equipment. In the automotive field, for ease of use, vehicle-mounted air pumps have been developed. The air inflator connector is the connection medium. One end is connected to the vehicle-mounted air pump, and the other end is connected to the car tire through the air inflator valve, which can inflate the tire in an emergency.
[0003] Currently, when a car tire pressure is found to be low, the corresponding tire needs to be inflated. First, the end with the inflation valve is installed on the tire valve stem, and then the tire is inflated by starting the air pump. However, in order to prevent collision damage, the end of the valve stem is generally set to be curved inward. Different cars have different valve stem orientations, while existing car inflation valves are all set in a straight shape. They cannot be adapted to valve stems with different end orientations during installation, resulting in installation difficulties. Therefore, we propose a car inflation valve. Utility Model Content
[0004] This invention addresses the shortcomings of existing technologies by providing a vehicle inflation valve that, through the cooperation of a bending component and a limiting component, allows the end that connects to the tire valve to be freely adjustable in direction, making it easy to adapt to valves with different orientations.
[0005] To solve the above-mentioned technical problems, the present invention solves the problem that the existing vehicle inflation valves are all set in a straight line, which cannot be adapted to valves with different end orientations during installation, resulting in installation difficulties.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A vehicle-mounted air inflator includes a valve body with a fixed tube communicating with its interior at the air outlet end; a bending assembly disposed on the fixed tube and connected to the tire valve stem, comprising a gooseneck tube disposed on and fixedly connected to the fixed tube, with a connecting tube fixedly connected to the end of the gooseneck tube away from the fixed tube; the bending assembly is used to change the original vertical placement of the air inflator; and a limiting assembly disposed outside the gooseneck tube and connected to the bending assembly, used to limit the gooseneck tube to its current bent state after adjustment. This solves the problem that, in order to prevent collision damage, the end of the valve stem is generally bent inwards, and different vehicles have different valve stem orientations, while existing vehicle-mounted air inflators are all straight, making it difficult to install and adapt to valve stems with different end orientations.
[0008] Preferably, the bending assembly further includes two sets of rotating seats respectively disposed on the fixed tube and the connecting tube. The outer sides of the fixed tube and the connecting tube are provided with annular grooves adapted to the rotating seats, and the rotating seats are threaded with bolts whose ends are in contact with the annular grooves.
[0009] Preferably, the limiting component includes a first rotating plate disposed on the rotating seat outside the connecting pipe, one end of the first rotating plate being disposed between the rotating seat and the bolt, a sliding block being fixedly connected to the other end of the first rotating plate, a placement groove being formed between the sliding block and the first rotating plate, a second rotating plate being disposed on the first rotating plate and closely attached thereto, one end of the second rotating plate being disposed between the rotating seat and the bolt, and the second rotating plate having a sliding groove adapted to the sliding block, the sliding block being connected to a fixing member connected to the first rotating plate.
[0010] Preferably, the fixing component includes a lifting block disposed in and slidably connected to the placement groove, a pad located above the second rotating plate fixedly connected to the outside of the lifting block, and a spring disposed in the placement groove fixedly connected to the bottom end of the lifting block, a threaded seat fixedly connected to the bottom end of the first rotating plate, a threaded rod threadedly connected to the threaded seat and passing through the lifting block, and a rotating block fixedly connected to the top end of the threaded rod.
[0011] Preferably, a rubber hose can be fitted over the outside of the gooseneck tube to enhance protection of the gooseneck tube and prevent damage to it.
[0012] Preferably, the gasket is made of rubber to increase friction, which helps to make the adjusted state more stable and prevents loosening and independent angle adjustment, which could cause the inflation valve to fall off the valve stem due to continuous oscillation.
[0013] Preferably, the rotating block has multiple sets of grooves for easy operation and rotation, which facilitates the rotation of the rotating block during adjustment and makes it easy to insert fingers into the grooves for operation.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This invention solves the problem that, in order to prevent collision damage, the end of the valve stem is usually bent inwards. Different cars have different valve stem orientations, while existing vehicle inflation valves are all straight, making it difficult to install and adapt to valve stems with different end orientations. This invention allows the end that connects to the tire valve stem to be freely adjustable in direction, making it easier to adapt to valve stems with different orientations. During adjustment, the restriction of the limiting component on the overall adjustment is first removed, and then the bending component is adjusted to change the position between the connecting pipe and the fixing pipe, thereby adapting to valve stems with different orientations and improving the applicability.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. Example
[0025] Please see Figures 1-6 A vehicle-mounted air inflator includes a valve body 1, with a fixed pipe 2 communicating with its interior at the air outlet end; a bending assembly 3, which is mounted on the fixed pipe 2 and connected to the tire valve stem, including a gooseneck tube 4 mounted on and fixedly connected to the fixed pipe 2, with a connecting pipe 5 fixedly connected to the end of the gooseneck tube 4 away from the fixed pipe 2; and a limiting assembly 6, which is located outside the gooseneck tube 4 and connected to the bending assembly 3, and is used to limit the gooseneck tube 4 to its current bent state after adjustment. To enhance protection of the gooseneck tube 4 and prevent damage, a rubber hose can be fitted over the outside of the gooseneck tube 4.
[0026] Please see Figures 1-4 The bending assembly 3 also includes two sets of rotating seats 7 respectively set on the fixed pipe 2 and the connecting pipe 5. The outer side of the fixed pipe 2 and the connecting pipe 5 are provided with annular grooves 8 that are adapted to the rotating seats 7. The rotating seats 7 are threaded with bolts 9 whose ends are in contact with the annular grooves 8. The bolts 9 pass through the top of the rotating seats 7 and their bottom ends can directly abut against the annular grooves 8.
[0027] Please see Figures 1-6The limiting component 6 includes a first rotating plate 10 disposed on the rotating seat 7 outside the connecting pipe 5. One end of the first rotating plate 10 is disposed between the rotating seat 7 and the bolt 9. A sliding block 11 is fixedly connected to the other end of the first rotating plate 10. A placement groove 12 is formed between the sliding block 11 and the first rotating plate 10. A second rotating plate 13 is disposed on the first rotating plate 10 and closely attached thereto. One end of the second rotating plate 13 is disposed between the rotating seat 7 and the bolt 9, and the second rotating plate 13 has a sliding groove 14 adapted to the sliding block 11. The sliding block 11 is connected to a fixing member 15 connected to the first rotating plate 10. The fixing member 15 includes a placement groove 14 connected to the first rotating plate 10. The lifting block 16 is slidably connected to the placement groove 12. A pad 17 located above the second rotating plate 13 is fixedly connected to the outside of the lifting block 16. A spring 18 set in the placement groove 12 is fixedly connected to the bottom end of the lifting block 16. A threaded seat 19 is fixedly connected to the bottom end of the first rotating plate 10. A threaded rod 20 passing through the lifting block 16 is threadedly connected to the threaded seat 19. A rotating block 21 is fixedly connected to the top end of the threaded rod 20. In order to make the adjusted state more stable, the pad 17 is made of rubber to increase friction. In addition, in order to facilitate the rotation of the rotating block 21 during adjustment, multiple sets of grooves are provided on the rotating block 21 to facilitate the rotation.
[0028] During implementation, when it is necessary to adjust the connection direction, first hold the rotating block 21 and rotate it. The rotating block 21 drives the threaded rod 20 to rotate at the same time. The threaded rod 20 is connected to the threaded seat 19 through the thread. The threaded rod 20 moves upward until it is disconnected from the threaded seat 19. At this time, the spring 18 in the placement groove 12 rebounds and pushes the lifting block 16 upward. The pad 17 at the top of the lifting block 16 rises upward at the same time and is disconnected from the second rotating plate 13 to prevent the pad 17 from rubbing against the second rotating plate 13 and affecting the adjustment. Then push the connecting pipe 5. At this time, the connecting pipe 5 drives the gooseneck tube 4 to bend. When the angle of the end of the connecting pipe 5 is adapted to the current tire valve angle, stop pushing.
[0029] During the pushing process, the rotating seat 7 drives the bolt 9 to move, and at the same time drives the first rotating plate 10 to move. The sliding block 11 at the end of the first rotating plate 10 slides in the sliding groove 14 on the second rotating plate 13. When the adjustment stops, the rotating block 21 is rotated in the opposite direction again, which drives the threaded rod 20 to move downward until the bottom end is connected to the threaded seat 19 again. During the downward movement, the rotating block 21 presses the gasket 17. When the adjustment stops, the gasket 17 is pressed tightly against the rotating block 21 and the second rotating plate 13, respectively, so that the gooseneck tube 4 is kept in its current state and prevents it from shaking continuously during the inflation process, which would cause the connecting pipe 5 to fall off the valve.
[0030] It is worth noting that when the valve is in different positions, before adjusting the gooseneck tube 4, the two sets of bolts 9 can be loosened by rotating them, so that the rotating seat 7 can rotate through the annular groove 8. After rotating to the desired position, the bolts 9 can be tightened on the rotating seat 7 again, which can adapt to valves with different orientations and improve the applicability.
