[0002] The vehicle-mounted air pump is also called an inflator, air pump, and air pump. It works by running an internal motor. In daily driving, accidents caused by uneven tire pressure occur from time to time. It can be seen that it is so important to maintain the tire pressure at all times while driving. When driving at high speed, tire blowouts are mainly caused by low tire pressure and high tire pressure. Therefore, when driving, carrying a high-quality vehicle-mounted air pump can not only ensure that the tires are inflated, but also improve driving safety and extend the service life of the tires.

[0003] When the vehicle-mounted air pump is in use, the car tire needs to be inflated through an air nozzle. Since the inflation heads on different tires are different, different air nozzles are required. Most of the existing vehicle-mounted air pumps have designated air nozzles, which are inconvenient to replace, causing inconvenience in the use of the vehicle-mounted air pump. Therefore, we propose a vehicle-mounted air pump that is easy to connect. Utility Model Content

[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] Example 1

[0026] Reference Figure 1-4 , which is the first embodiment of the utility model, provides a vehicle-mounted air pump that is easy to connect, including an air pump body 1, an air pipe 2 is fixedly connected to the front of the air pump body 1, and the right end of the air pipe 2 includes:

[0027] The mounting assembly 3 includes a mounting shell 31. The right end of the inflation tube 2 is arranged inside the mounting shell 31. A gas nozzle 32 is arranged on the right side of the mounting shell 31. A connecting end 33 is fixedly connected to the left side of the gas nozzle 32. The connecting end 33 is arranged inside the mounting shell 31.

[0028] The connecting component 4 includes a mounting ring 41, which is arranged on the surface of the air nozzle 32. Two mounting grooves 42 are provided on the right side of the mounting ring 41. A rotating ring 43 is provided on the left side of the mounting ring 41. The rotating ring 43 is arranged on the surface of the mounting shell 31. An annular groove is provided on the inner wall of the rotating ring 43. The inner wall of the annular groove is slidably connected to the surface of the mounting shell 31 through an annular slider. The surface of the rotating ring 43 is provided with anti-slip grooves. Blocks 44 are fixedly connected to the upper and lower sides of the right side of the rotating ring 43. The block 44 is set to be L-shaped.

[0029] A sealing ring 34 is fixedly connected to the left side of the air nozzle 32, a sealing gasket 35 is fixedly connected to the right side of the inner wall of the mounting shell 31, a card slot 311 is opened on the front and rear sides of the inner wall of the mounting shell 31, a card strip 331 is fixedly connected to the front and rear sides of the connecting end 33, and the card strip 331 is arranged inside the card slot 311, and the inner wall of the mounting ring 41 is fixedly connected to the left side of the surface of the air nozzle 32.

[0030] A connecting shell 45 is fixedly connected to the surface of the mounting shell 31, and arc grooves are provided on the upper and lower sides of the right side of the connecting shell 45. A reset assembly 46 is provided inside the connecting shell 45. Two groups of reset assemblies 46 are provided, and the two groups of reset assemblies 46 are respectively arranged on the upper and lower sides of the inside of the connecting shell 45. The two reset assemblies 46 are arranged oppositely. The reset assembly 46 includes an arc rod 461, and a sliding block 462 is slidably connected to the surface of the arc rod 461. A reset spring 463 is sleeved on the rod wall of the arc rod 461.

[0031] The two ends of the arc rod 461 are fixedly connected to the two sides of the inner wall of the connecting shell 45, the two ends of the return spring 463 are respectively fixedly connected to one side of the inner wall of the connecting shell 45 and one side of the sliding block 462, and the right side of the sliding block 462 is fixedly connected to the left side of the rotating ring 43.

[0032] During use, a designated air nozzle 32 is installed on the mounting shell 31 according to the size of the tire inflation head. When installing the air nozzle 32, the connecting end 33 on the air nozzle 32 is inserted into the mounting shell 31, and the clamping strip 331 on the connecting end 33 is inserted into the clamping groove 311 in the mounting shell 31. Under the action of the sealing ring 34 and the sealing gasket 35, the sealing between the mounting shell 31 and the air nozzle 32 and the connecting end 33 is increased.

[0033] At the same time, the rotating ring 43 is rotated so that the rotating ring 43 drives the clamping block 44 to rotate and deviate, so that the clamping block 44 can be inserted into the mounting groove 42 on the mounting ring 41. When the rotating ring 43 rotates, the rotating ring 43 drives the sliding block 462 to rotate, and the sliding block 462 slides on the arc rod 461 in the connecting shell 45. At this time, the reset spring 463 is compressed. After the clamping block 44 is inserted into the mounting groove 42, the rotating ring 43 is released. Under the reset elastic action of the reset spring 463, the sliding block 462 is driven to move, and the rotating ring 43 is driven by the sliding block 462 to reset and rotate. At this time, the clamping block 44 slides in the mounting groove 42, and the convex part of the clamping block 44 is misaligned with the mounting groove 42, so that the clamping block 44 is stuck on the mounting ring 41, so that the air nozzle 32 is installed on the mounting shell 31, which is convenient for installing the air nozzle 32.

[0034] After the connection end 33 is installed, the connection end 33 is connected to the inflation head on the wheel. The inflation pump body 1 transports the gas to the mounting shell 31 through the inflation pipe 2. The gas in the mounting shell 31 enters the air nozzle 32 through the connection end 33, and the gas inflates the wheel.

[0035] Example 2

[0036] Reference Figure 1-4 , which is the second embodiment of the utility model, a one-way component 36 is arranged inside the mounting shell 31, and the one-way component 36 includes a sealing retaining ring 361, and a ball valve 362 is arranged on the left side of the sealing retaining ring 361. A pagoda spring 363 is fixedly connected to the left side of the ball valve 362, and the left end of the pagoda spring 363 is fixedly connected to a limiting ring 364. A connecting rod 365 is fixedly connected to the right side of the ball valve 362, and the connecting rod 365 is arranged inside the sealing retaining ring 361. A push rod 366 is fixedly connected to the right end of the connecting rod 365, and the push rod 366 is arranged on the right side of the sealing retaining ring 361. Slide grooves are provided on the upper and lower sides of the inner wall of the mounting shell 31, and the upper and lower ends of the one-way component 36 are slidably connected to the inner wall of the slide groove, and the right side of the push rod 366 contacts the left end of the connecting end 33.

[0037] The surface of the sealing retaining ring 361 is fixedly connected to the right side of the inner wall of the mounting shell 31 , and the surface of the limiting ring 364 is fixedly connected to the left side of the inner wall of the mounting shell 31 .

[0038] During use, when the air nozzle 32 is not installed on the mounting shell 31, under the elastic action of the pagoda spring 363, the pagoda spring 363 on the limit ring 364 generates elastic pressure on the ball valve 362, squeezing the ball valve 362 into the interior of the sealing retaining ring 361 so that the gas generated by the inflation pump body 1 cannot be discharged through the mounting shell 31, thereby maintaining the sealing of the mounting shell 31. After the air nozzle 32 is installed on the mounting shell 31, the connecting end 33 on the air nozzle 32 squeezes the push rod 366, so that the push rod 366 drives the ball valve 362 to push through the connecting rod 365, pushing the ball valve 362 away from the sealing retaining ring 361. At this time, the gas generated by the inflation pump body 1 can enter the connecting end 33 and the air nozzle 32 through the mounting shell 31.

[0039] The remaining structures are the same as those of Example 1.
