Description

Technical Field

[0001] This utility model relates to the field of handheld air pump technology, and in particular to a handheld air pump clamping and fixing device. Background Technology

[0002] An air pump is a device that generates air pressure by continuously compressing air to expel or add air to a closed space. Air pumps are used for functions such as pumping air, inflating, vacuuming, pressurizing, and circulating gas. Handheld electric air pumps are small and portable, allowing you to easily inflate car tires when tire pressure drops.

[0003] However, existing handheld air pumps have some problems in use. In order to make them easy for users to carry, they are generally small in size and have short air tubes for delivering air. After connecting the air pump to the tire, the short air tube is often not enough to place the air pump on the ground. Suspending the air pump directly through the air tube can easily cause it to shake and loosen the valve, affecting inflation. Therefore, users usually need to squat down and hold the air pump by hand to inflate the tire, which causes some discomfort. In addition, existing air pumps have an air inlet, which is easily blocked by dust when the air pump is not in use. Long-term accumulation of dust will affect the use of the air pump.

[0004] Therefore, it is necessary to invent a handheld air pump clamping and fixing device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a handheld air pump clamping and fixing device to solve the problems mentioned in the background art.

[0024] A receiving groove 7 is provided through the middle of the movable plate 4. A movable frame 8 is provided inside the receiving groove 7. A support pin 9 is fixed at the top of the movable frame 8 and is rotatably located at the top of the receiving groove 7. A torsion spring is provided between the movable frame 8 and the inner wall of the top of the receiving groove 7. Vertical ribs 10 are provided on both sides of the movable frame 8. A horizontal rib 11 is provided at the middle of the bottom end of the movable frame 8. Both the vertical ribs 10 and the horizontal ribs 11 are arc-shaped. A positioning block 12 is fixed at the bottom of the inner side wall of the receiving groove 7 and is adapted to the horizontal rib 11. The positioning block 12 is used to press against the horizontal rib 11 so that the movable frame 8 is limited in the receiving groove 7 under the action of the torsion spring.

[0025] The bottom of the inner walls on both sides of the groove 2 is provided with a strip-shaped sliding groove 13. Multiple positioning holes 14 are provided from bottom to top on the bottom of the groove 13. Slots 15 are provided on both sides of the bottom of the support plate 6. A rod 16 is slidably inserted into the inside of the slot 15 and is adapted to the positioning hole 14. One end of the rod 16 is a hemispherical structure. When it is subjected to external force, it can squeeze the groove of the positioning hole 14 and slide into the slot 15 under the squeezing action.

[0026] A spring is provided between one end of the insertion rod 16 and the bottom of the slot 15. A ring-shaped limiting groove 17 is provided in the middle of the inner side wall of the slot 15. A ring-shaped limiting block 18 is fixedly provided at one end of the insertion rod 16, and the limiting block 18 is slidably disposed inside the limiting groove 17. The limiting block 18 and the limiting groove 17 are used to limit the sliding range of the insertion rod 16. When the insertion rod 16 is squeezed and slides into the slot 15, one end of it remains in the sliding groove 13 to prevent one end of the support plate 6 from separating from the groove 2.

[0027] A square groove 19 is provided around the middle of the outer side wall of the air pump body 1. An air guide tube 20 is provided inside the square groove 19. The design of the square groove 19 can accommodate a longer air guide tube 20 for the convenience of the user.

[0028] One end of the air guide tube 20 is connected to the interior of the air pump body 1. A rubber bracket 21 is fixedly provided at the top of one side inner wall of the square groove 19, and the rubber bracket 21 is adapted to the air guide tube 20. The rubber bracket 21 is used to clamp one end of the air guide tube 20. It should be noted that the air pump body 1 is equipped with a battery, air pump, controller and other structures.

[0029] Working principle of this utility model:

[0030] When using this device, the user can pull one end of the air guide tube 20 to separate the air guide tube 20 from the rubber bracket 21, then take the air guide tube 20 out of the square groove 19, connect one end of the air guide tube 20 to the car tire valve, and then start the air pump inside the air pump body 1 to inflate the car tire.

[0031] During use, the user can pry open the gap between the movable plate 4 and the support plate 6, causing the movable plate 4 and the support plate 6 to move away from the groove 2. At this time, the rod 16 at one end of the support plate 6 is pulled by the support plate 6, and the end of the rod 16 is squeezed by the groove of the positioning hole 14, causing the rod 16 to slide into the slot 15. At this time, the bottom end of the support plate 6 can slide along the inner wall of the groove 2. At this time, the movable plate 4, the support plate 6 and the air pump body 1 form a triangular structure to support the air pump body 1, and the support plate 6 is separated from the air inlet 3 to ensure that the air pump body 1 can complete the inflation work.

[0032] After the movable plate 4 and the support plate 6 are unfolded, the user can turn the horizontal rib 11 to make it rotate the movable frame 8. The movable frame 8 flips to the outside of the receiving groove 7, and then the movable frame 8 is inserted into the inside of the car wheel hub. At this time, the movable frame 8 clamps the car wheel hub under the action of the torsion spring. If the air pump body 1 is perpendicular to the car wheel hub, the vertical rib 10 can be inserted into the edge of the car wheel hub. If the air pump body 1 is horizontal to the car wheel hub, the horizontal rib 11 can be inserted into the edge of the car wheel hub. At this time, the movable frame 8 can clamp and fix the air pump body 1 on the car wheel hub, so that the user does not need to hold the air pump body 1 to inflate.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
