[0044] like Figure 4 and Figure 5 As shown, the left side of the bracket 15 is provided with a sawtooth groove distributed vertically up and down.

[0045] When the car tire needs to be inflated, the driver can first lift the lifting rod 12 upwards, the lifting rod 12 will first rotate upwards to a certain angle, and then move upwards with the air pump 1 and other components, so as to take the air pump 1 and other components out of the trunk of the car, and the upward rotation of the lifting rod 12 will drive the top block 14 to rotate downwards, and the downward rotation of the top block 14 will contact and squeeze the support frame 15, so that the support frame 15 moves to the right and separates from the moving plate 18, and the compression spring 111 is immediately compressed.

The lifting rod 12 will rotate downward and reset under its own gravity, and the top block 14 will rotate upward and reset immediately. The bracket 15 will move to the left and reset under the action of the compression spring 111 and contact the movable plate 18, so that the upper and lower movable plates 18 are both stuck in the serrated grooves of the bracket 15, so that the movable plate 18 and the guide wheels 17 and the movable plate 18 are locked in the serrated grooves of the bracket 15. The wheel 17 and the connecting tube 11 are limited and fixed to prevent the connecting tube 11 from automatically recovering after accidentally letting go. After that, the driver can connect the valve port of the connecting tube 11 with the air valve of the tire, and then start the air pump 1 and inflate the tire through the connecting tube 11. After the inflation is completed, the valve port of the connecting tube 11 can be removed from the air valve of the tire, and then the air pump 1 can be put back into the trunk of the car with the help of the lifting rod 12. During this period, the lifting rod 12 will first rotate upward, and the top block 14 will rotate downward and squeeze the bracket 15, so that the bracket 15 moves to the right and separates from the movable plate 18. , the compression spring 111 is immediately compressed, and the guide wheels 17 and the movable plate 18 on the upper and lower sides will move backwards and reset under the action of the elastic pull rope 19, and the connecting tube 11 will also retract into the protective shell 13 under the action of the guide wheel 17, so that the connecting tube 11 can be automatically stored after use, thereby reducing the labor intensity of the user and improving the user's experience. After that, the lifting rod 12 will rotate downward and reset under the action of its own gravity, the top block 14 will rotate upward and reset, and the support frame 15 will move to the left and reset under the action of the compression spring 111.

[0046] Example 2

[0047] On the basis of Example 1, Figure 6-Figure 9As shown, it also includes a winding mechanism, which is arranged on the air pump 1. The winding mechanism includes a connecting clamp 2, a conductive wire 21, a rope winding drum 22, a spring 23, a first connecting rope 24, a second sliding rod 25, a clamping block 26 and a tension spring 27. The two connecting clamps 2 are respectively clamped on the front and rear parts of the left side of the air pump 1. The front and rear parts of the left side of the air pump 1 are both fixedly connected with the conductive wire 21. One end of the conductive wire 21 away from the air pump 1 is fixedly connected to the connecting clamp 2. The front and rear parts of the left side of the air pump 1 are both rotatably connected with the rope winding drum 22. The conductive wire 21 is wound around It is connected to the adjacent rope winding drum 22, a clockwork spring 23 is fixedly connected between the rope winding drum 22 and the air pump 1, the front and rear parts of the left side of the air pump 1 are slidably connected with the second slide bar 25, a tension spring 27 is fixedly connected between the second slide bar 25 and the air pump 1, a clamping block 26 is fixedly connected to the bottom end of the second slide bar 25, the clamping block 26 is squeezed and fitted with the adjacent rope winding drum 22, the front and rear sides inside the air pump 1 are slidably connected with the first connecting rope 24, one end of the first connecting rope 24 is fixedly connected to the lifting rod 12, and the other end of the first connecting rope 24 is fixedly connected to the adjacent second slide bar 25.

[0048] like Figure 7-Figure 9 As shown, one side of the rope winding drum 22 close to the adjacent clamping block 26 is provided with clamping grooves which are evenly distributed around the circumference.

[0049] like Figure 8 and Fig. 9 As shown, the shape of the block 26 is a trapezoid.

[0050] When the air pump 1 needs to be charged, the connecting clamps 2 on the front and rear sides can be removed first, and then the conductive wire 21 can be pulled out to a suitable length through the connecting clamps 2. During this period, the conductive wire 21 being pulled out will drive the rope drum 22 to rotate counterclockwise, and the spring 23 will be deformed immediately. The counterclockwise rotation of the rope drum 22 will first squeeze the block 26, and move the block 26 and the second slide bar 25 upward, and the tension spring 27 will be stretched immediately. When the rope drum 22 rotates until the slot corresponds to the block 26 and stops rotating, the block 26 and the second slide bar 25 will move downward and reset and snap into the slot under the action of gravity and the tension spring 27, so as to limit and fix the rope drum 22 and the conductive wire 21 to avoid automatic recovery of the conductive wire 21 after accidental release. After that, the driver can clamp and fix the connecting clamps 2 on the front and rear sides respectively on the outside The positive and negative poles of the power supply are used to charge the air pump 1. After charging is completed, the connecting clamp 2 is first removed from the external power supply and put back in place, and then the lifting rod 12 is lifted upward. The upward rotation of the lifting rod 12 will pull the first connecting rope 24, thereby driving the clamping block 26 and the second sliding rod 25 to move upward, and the tension spring 27 is immediately stretched. At this time, the rope winding drum 22 will rotate clockwise to reset under the action of the spring 23, and the conductive wire 21 will be rewound and stored, so that the conductive wire 21 can be automatically stored after use, thereby reducing the labor intensity of the user and improving the user's experience. After loosening the lifting rod 12, the lifting rod 12 will rotate downward to reset under the action of its own gravity, the first connecting rope 24 will be loosened immediately, and the clamping block 26 and the second sliding rod 25 will move downward to reset under the action of gravity and the tension spring 27.

[0051] like Figure 10-12 As shown, it also includes an injection mechanism, which is arranged on the air pump 1. The injection mechanism includes a spray plate 3, an air guide tube 31, an extrusion plate 32, a spring 33, a switch valve 34, a second connecting rope 35 and an air injection tube 36. The spray plate 3 is fixedly connected to the right side of the air pump 1. The air guide tube 31 is fixedly connected to the rear right side of the air pump 1. One end of the air guide tube 31 is connected to the connecting tube 11, and the other end of the air guide tube 31 is connected to the cavity at the rear right side of the air pump 1. The middle of the air guide tube 31 A one-way valve is fixedly connected, and an extrusion plate 32 is slidably connected in the cavity at the right rear of the air pump 1. Two left and right spring plates 33 are fixedly connected between the extrusion plate 32 and the air pump 1. An air injection pipe 36 is fixedly connected and connected to the left side of the cavity at the right rear of the air pump 1. The end of the air injection pipe 36 away from the cavity at the right rear of the air pump 1 is connected to the spray plate 3. The right part of the air injection pipe 36 is rotatably connected to the switch valve 34, and a second connecting rope 35 is fixedly connected between the lifting rod 12 and the switch valve 34.

[0052] When the air pump 1 is started and the tire is inflated through the connecting pipe 11, part of the gas output by the air pump 1 will be injected into the cavity at the right rear side of the air pump 1 through the connecting pipe 11 and the air guide pipe 31. As the air pressure in the front of the cavity continues to increase, the extrusion plate 32 will be squeezed by the air and move backwards, and the spring piece 33 will be deformed and compressed immediately. When the inflation is completed and the air pump 1 is turned off, due to the one-way valve on the air guide pipe 31, the gas in the cavity will not be ejected outward through the air guide pipe 31 and the connecting pipe 11. When the driver turns off the air pump 1 and puts the air pump 1 back into the trunk of the car with the help of the lifting rod 12, the lifting rod 12 The second connecting rope 35 will rotate upward and drive the switch valve 34 to rotate upward and open. At this time, the extrusion plate 32 will move forward and reset under the action of the spring 33, and the gas in the cavity will be squeezed by the extrusion plate 32 and enter the spray plate 3 through the gas injection pipe 36, and finally be sprayed out from the spray plate 3, so that the gas sprayed from the spray plate 3 can be used to cool the air pump 1 and blow off dust and other impurities on the surface of the air pump 1. After the driver releases the lifting rod 12, the lifting rod 12 will rotate downward and reset under the action of its own gravity, and the second connecting rope 35 will be loosened immediately, and the switch valve 34 will rotate downward and close under the action of its own gravity.

[0053] like Fig.13 and Fig.14 As shown, it also includes a limiting mechanism, which is arranged on the air pump 1. The limiting mechanism includes an air cylinder 4, an air pipe 41, a piston rod 42 and a spring 43. The air cylinder 4 is fixedly connected to the front right part of the air pump 1, and the air pipe 41 is fixedly connected to the front side of the air pump 1. One end of the air pipe 41 is connected to the air cylinder 4, and the other end of the air pipe 41 is connected to the connecting pipe 11. A piston rod 42 is slidably connected inside the air cylinder 4, and a spring 43 is fixedly connected between the piston rod 42 and the air cylinder 4, and the piston rod 42 is in contact with the lifting rod 12.

[0054] When the air pump 1 is started and the tire is inflated through the connecting pipe 11, part of the gas output by the air pump 1 will enter the air cylinder 4 through the connecting pipe 11 and the air supply pipe 41. As the air pressure at the rear of the air cylinder 4 continues to increase, the piston rod 42 will be squeezed by the air and move forward, and the spring 43 will be compressed immediately. The forward movement of the piston rod 42 will contact the lifting rod 12 and limit and fix it, so as to prevent the lifting rod 12 from accidentally rotating upward due to the mechanical vibration generated by the operation of the air pump 1 and unlocking the rope drum 22 and the movable plate 18, thereby causing the conductive wire 21 and the connecting pipe 11 to be accidentally recovered and affect their use. When the driver turns off the air pump 1, the piston rod 42 will move backward and reset under the action of the spring 43, thereby squeezing the gas at the rear of the air cylinder 4 into the connecting pipe 11 through the air supply pipe 41 and finally discharged to the outside.

[0055] like Fig.15 and Fig.16As shown, a storage mechanism is also included, which is arranged on the air pump 1. The storage mechanism includes a placement rack 5 and a spare valve port 51. The placement rack 5 is slidably connected to the right front side of the air pump 1, and the upper and lower sides of the placement rack 5 are clamped with spare valve ports 51 symmetrically distributed on the left and right.

[0056] When inflating a car tire by means of the air pump 1 and the connecting pipe 11, the valve port on the connecting pipe 11 may be worn out due to repeated use and affect subsequent use. In addition, the connecting pipe 11 may not be usable because the size of the valve port does not match the size of the tire valve. At this time, the driver can pull the placement rack 5 forward, then remove the appropriate spare valve port 51 on the placement rack 5 and replace the valve port on the connecting pipe 11. In this way, the user can quickly replace the spare valve port 51 when the valve port is damaged or the size does not match, thereby ensuring that the air pump 1 can continue to be used normally, thereby improving the user's experience. After the replacement is completed, the placement rack 5 can be moved backward to reset.

[0057] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
