Description

Inflator

technical field

The utility model relates to an air pump.

Background technique

At present, the common pump structure for bicycles is mostly to set the pump as a super miniature type, and to carry it with the bicycle, such as the structure shown in the previous case of Taiwan Publication No. 465676 Patent, which mainly uses a cylinder body The pump rod is arranged in the axial direction, and the external air is driven into the bicycle tire by the pump rod reciprocatingly moving; however, although this structure is small in size and can be installed anywhere with the bicycle, it needs to be fixed by other fixing elements Being arranged on the bicycle, the pump is extremely easy to lose, and the overall structure has the disadvantage of being difficult to store.

Utility model content

The purpose of the utility model is to provide an air pump that can be stored along with the vehicle.

In order to achieve the above purpose, the solution of the utility model is: an air pump, which mainly includes components such as an air intake seat tube, a pump rod, and an air intake pipe; wherein:

The top of the air intake seat tube is provided with a fixed unit for fixing the seat cushion, and an air outlet is arranged on it, and a check valve is provided in the direction of the air intake of the air intake seat tube and the air outlet of the air outlet;

Both ends of the air intake pipe are provided with air intake nozzles respectively connected to the air outlet nozzle of the fixed unit and the air nozzle of the tire;

The top end of the pump rod is a hollow housing tube with a sealing piston plugged in and stretched into the intake seat tube. The bottom end of the pump rod is covered with a solidification block with external threads, and the end of the pump rod is screwed with a bottom cover. .

When assembling, the intake pipe is accommodated in the pump rod accommodation tube, the upper bottom cover of the pump rod is screwed relative to the consolidation block and then locked at the bottom of the intake seat tube, and the intake pipe is sealed by the bottom cover and hidden in the storage tube.

In the pump described above, a through hole with a larger diameter than the intake pipe is axially pierced in the center of the bottom cover of the pump rod, and a fixed plug is provided to close the intake pipe in the pump rod.

After the above-mentioned structure is adopted, the utility model is a bicycle seat tube under normal conditions. If the tire needs to be inflated, it can be removed and used as an air pump. Compared with conventional products, the utility model can be stored with the vehicle and is not easy to lose.

Detailed ways

As shown in Figure 1, the utility model mainly includes components such as intake seat pipe 1, pump rod 2 and intake pipe 3, wherein:

A fixed unit 11 is fixed on the top of the air intake seat tube 1, and a bicycle seat cushion can be fixed on its top, and the fixed unit 11 is provided with an air outlet nozzle 12, and the air intake and air outlet nozzle 12 are provided on the air intake direction of the air intake seat tube 1 relative to the air intake seat tube 1. There is a check valve 13, and an internal thread 14 is provided below the intake seat pipe 1.

The pump rod 2 is an inner hollow containing tube 21 with a sealing piston 22 plugged on its top end, and a consolidation block 23 with an external thread and an O-ring 231 are sleeved at the bottom end, and screwed at the end of the pump rod 2. Bottom cover 24, the bottom cover 24 and the consolidation block 23 are screwed to each other, and are screwed to the internal thread 14 at the bottom of the intake seat tube 1 by the consolidation block 23;

Both ends of the air intake pipe 3 are provided with air intake nozzles 31, 32, which are respectively connected to the air outlet nozzle 12 on the fixed unit 11 and the air nozzle of the tire 4 (see FIG. 4).

When assembling, as shown in Figure 2, let the intake pipe 3 be accommodated in the accommodation pipe 21 of the pump rod 2 first, and then screw the bottom cover 24 on the consolidation block 23 sleeved on the pump rod 2, and consolidate The block 23 is fixed together with the pump rod 2 on the internal thread 14 at the end of the intake seat tube 1, so that the intake tube 3 and the pump rod 2 can be axially extended and accommodated in the intake seat tube 1. If you want to use , unplug the air intake seat pipe 1 from the bicycle, as shown in Figure 3 and 4, make the air outlet nozzle 12 of the fixed unit 11 face the tire 4, unscrew the bottom cover 24 relative to the accommodating pipe 21, and take out the air intake pipe 3 first. Then the bottom cover 24 is screwed to the end of the housing tube 21, and the bottom cover 24 is rotated back relative to the solidification block 23, so that the pump rod 2 can be moved axially in the air intake seat tube 1, and then the air intake pipe 3 can be moved in two directions. The air intake nozzles 31 and 32 at the end are respectively connected to the air nozzle of the tire 4 and the air outlet nozzle 12 of the fixed unit 11, so that the air can be pushed against the air intake seat tube 1 by pulling the pump rod 2 back and forth, so that the air intake The seat tube 1 can absorb external air and push it through the pump rod 2, and send it to the tire 4 by the air intake pipe 3 for inflation.

As shown in Figure 5, it is another embodiment of the utility model, the bottom cover 24 at the end of the intake seat tube 1 is axially provided with a through hole 241' that is larger in diameter than the intake tube 3, and by an elastic fixing The plug 26 is inserted therein so as to close the housing tube 21 of the pump rod 2, and limit the accidental escape of the air intake tube 3 from the housing tube 21. If you want to use it, you only need to remove the fixing plug 26, and you don't need to unscrew the bottom cover 24' The intake pipe 3 can be taken out through the through hole 241'.
