Technical Field

[0001] The utility model relates to the technical field of air pumps, in particular to a labor-saving pedal-type air pump. Background Art

[0002] The inflator is also called an air pump, an air pump, and an inflation pump. It works by running a motor. When the inflator is operated by a motor, the valve of the communicating device is opened by the atmospheric pressure, and the gas enters the cylinder. When air is inflated into the tire, the valve is closed by the air pressure in the cylinder, and the gas enters the tire. This can be regarded as using the principle of atmospheric pressure to inflate cars, balls, and rubber boats.

[0003] In the related art, most of the connecting tubes of the existing foot-operated air pumps are connected to the foot-operated air pumps by plugging them in, which causes the connecting tubes to easily fall off during use, reducing the practicality of the foot-operated air pump. Therefore, we propose a labor-saving foot-operated air pump.

[0004] The above information disclosed in this Background section is only for understanding the background of the present inventive concept and therefore it may contain information that does not constitute prior art. Utility Model Content

[0005] The purpose of the utility model is to provide a labor-saving foot-operated air pump to solve the problem that most of the connecting pipes of the existing foot-operated air pumps proposed in the above background technology are connected to the foot-operated air pump by plugging, which causes the connecting pipe to fall off easily during use, reducing the practicality of the foot-operated air pump.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The yoke is provided with a plurality of yokes, and the yokes are provided with a plurality of yokes at the top end of the plurality of yokes, and the yokes are provided with a plurality of yokes at the top end of the plurality of yokes.

[0008] In some embodiments, two groups of mounting plates are fixedly and symmetrically installed on the right side of the mounting base plate, and a threaded rod is rotatably arranged inside the mounting plate. The upper end of the threaded rod passes through the mounting plate and is connected to the lower output end of the driving motor.

[0009] In some embodiments, the lower end of the threaded rod is rotatably set in a movable sleeve, and the movable sleeve is fixedly installed at the inner lower end of the mounting plate. The threaded rod includes a first thread segment and a second thread segment, and the thread directions of the first thread segment and the second thread segment are opposite.

[0010] In some embodiments, a clamping plate is symmetrically installed at the upper and lower ends of the inflation port, and the clamping plate is provided with a clamping groove at a corresponding position of the inflation port, and a buffer layer is glued inside the clamping groove.

[0011] In some embodiments, connecting plates are integrally formed on the left and right sides of the card plate, and a threaded rod is penetrated through the interior of the connecting plate, and the interior of the connecting plate is threadedly engaged with the threaded rod.

[0012] In some embodiments, a plurality of groups of support columns are symmetrically installed on the left and right sides of the lower end of the mounting base plate, and a battery is installed on the right side of the front end of the mounting base plate.

[0013] The beneficial effects of the utility model are:

[0014] The air pump is driven by pedaling, which significantly reduces the user's physical exertion and improves the inflation efficiency compared to a hand-operated air pump. The design uses a rubber spring to connect the pedal and the air pump, which not only cushions the impact force when the pedal is stepped on, but also increases the overall stability of the equipment, making the inflation process smoother. At the same time, the air pump is fixedly installed on the mounting base, and the buffering effect of the rubber spring can better adapt to different working environments and reduce the impact of vibration; the inflation port is equipped with a friction sleeve, which can be flexibly adjusted according to the diameter of the connecting pipe. In addition, the friction sleeve design on the outside of the connecting pipe significantly enhances the connection stability between the connecting pipe and the air pump, preventing it from falling off due to loose connection during inflation, ensuring safety and continuity of use; through the intelligent adjustment system of the drive motor and the threaded rod, automatic control of the clamping force of the inflation port and the connecting pipe is realized. Users can adjust the distance between the upper and lower pallets according to actual needs, further improving the tightness of the connection and the convenience of use. The buffer layer added to the pallet design effectively reduces the direct wear between the pallet and the connecting pipe and extends the service life of the equipment. At the same time, the design of the arc-shaped card slot and the buffer layer optimizes the feel during the connection process and makes the operation smoother. BRIEF DESCRIPTION OF THE DRAWINGS

One end of the inflation port 12 is connected to the air outlet of the air pump 9. A friction sleeve 13 is installed on the outer side of the inflation port 12. The friction sleeve 13 can be flexibly selected according to the aperture of the connecting pipe connected to the inflation port 12. The connecting pipe is sleeved on the outside of the friction sleeve 13 to increase the friction between the friction sleeve 13 and the connecting pipe, thereby improving the connection stability of the connecting pipe.

[0023] When the embodiments of the present utility model are implemented, Figure 1 , 2 As shown, two groups of mounting plates 10 are fixedly and symmetrically installed on the right side of the mounting base plate 1, and a threaded rod 15 is rotatably installed inside the mounting plate 10.

Through the precise control of the motor, the clamping plate 14 can tightly clamp the friction sleeve 13 and the connecting pipe to ensure the sealing and stability of the connection; the user steps on the pedal 7, and connects the right side of the pedal 7 with the first The connection of the two articulated seats drives the air pump 9 to work, and the downward pressing action of the pedal 7 is buffered by the rubber spring 8, which not only transmits sufficient power but also reduces the operational impact and improves the comfort of use; the air pump 9 starts to work, the air is compressed and transported to the connecting pipe through the air outlet, and finally reaches the object that needs to be inflated. During the inflation process, due to the close combination of the clamping plate 14 and the friction sleeve 13 on the outside of the connecting pipe, and the assistance of the buffer layer in the clamping groove 18, the connecting pipe is effectively prevented from falling off due to air pressure or operational vibration, and good inflation continuity is maintained; when the air is inflated to the required pressure, the user stops pedaling and the air pump 9 stops working.
