Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Furthermore, the technical features mentioned in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

Referring to fig. 1, an embodiment of the present invention provides an inflation pump 100, which includes a housing 200 and a movement 300 disposed in the housing 200. This movement 300 may include: hollow cylinder, cylinder head, connecting rod. The cylinder head is connected to the first end of the cylinder and has an outlet fitting in communication with the interior of the cylinder. The end of the connecting rod is provided with a piston which extends into the cylinder from a second end opposite to the first end of the cylinder. When the connecting rod is pushed, the piston moves toward the first end of the cylinder, and the volume of a space (cylinder compression chamber) defined between the piston and the first end of the cylinder becomes smaller, thereby causing the air pressure of the cylinder compression chamber to increase. When the air pressure in the cylinder compression chamber is higher than the ambient air pressure, the check valve in the cylinder head is pushed open, so that the air in the cylinder compression chamber flows into the cylinder head.

Referring to fig. 2-5, the air pump 100 further includes an air charging connector 400, and the connector 400 is connected to the air discharging connector. The inflation connector 400 includes: an air tube 30; a hollow valve core attachment 20, the valve core attachment 20 being connected to the air tube 30, a portion of an inner peripheral surface of the valve core attachment 20 being provided with an internal thread 21; a connector housing 50, the valve core connector 20 being received in the connector housing 50.

In one embodiment, the inner peripheral surface of the valve core attachment member 20 includes n internal threads 21, where 2. Ltoreq. N.ltoreq.4, n being selected according to the air pressure of the inflation pump.

With the above configuration, the inflation connector 400 can be connected to the valve core 500 of an object to be inflated (e.g., a tire) by screwing. Compared with the conventional inflation connector, only part of the inner peripheral surface of the valve core connector 20 of the inflation connector 400 is provided with the internal thread 21 (for example, only 2-4 circles of the internal thread 21), so that a user can conveniently and quickly connect the inflation connector 400 and the valve core 500 together, and because the valve core connector 20 only has 2-4 circles of the internal thread 21, because the number of the circles of the internal thread is relatively small, the resistance between the internal thread 21 and the external thread on the valve core 500 is gradually reduced in the rotation process of the valve core connector 20 relative to the valve core 500, thereby being beneficial to avoiding that the inflation connector cannot be screwed down due to the large resistance between the internal thread and the external thread of the valve core in the conventional inflation connector, and further air leakage occurs in the inflation process.

In one embodiment, the valve core connector 20 and the air tube 30 are connected together by an air tube connector 10. The air charging connector 400 is communicated with the air outlet connector of the movement 300 through the air pipe 30. The air pipe joint 10 includes a through hole extending from one end thereof to the opposite end thereof.

In one embodiment, the outer circumferential surface of the air pipe joint 10 is formed with a plurality of protrusions 11 having tapered surfaces around the outer circumferential surface to constitute a pagoda joint. In this manner, the air pipe coupler 10 can be quickly and reliably inserted into the air pipe 30.

In one embodiment, the valve core attachment member 20 includes a first hole 22, a second hole and a third hole 23 communicating with each other, the second hole being located between the first hole 22 and the third hole 23 and having a diameter smaller than the first hole 22 and the third hole 23, the internal thread 21 being formed on an inner peripheral surface of the second hole. The air pipe connector 10 is partially received in the third hole 23. In some conventional inflation joints, the internal threads of the valve core attachment member extend inwardly from the open end thereof. The present invention provides a guiding feature when the valve core connector 20 is screwed to the external thread of the valve core 500 without an internal thread in the first hole 22.

In one embodiment, the inflation fitting 400 further includes a sealing ring 40 sandwiched between one end of the internal threads 21 and the air tube fitting 10. After the inflation connector 400 and the valve core 500 are coupled, the end of the valve core 500 tightly abuts against the sealing ring 40, and the sealing ring 40 is elastically deformed to seal between the valve core 500 and the valve connector 10, thereby preventing air leakage.

In one embodiment, the inflation fitting 10 further includes a connector housing 50, and the valve core connector 20 is received in the connector housing 50. In the present embodiment, the valve core attachment 20 and the attachment housing 50 are secured together by integral molding. The connector housing 50 may be made of plastic.

Referring to FIG. 3, in one embodiment, the valve core attachment 20 is free to rotate relative to the air pipe fitting 10. Since the inflation connector 10 and the connector housing 50 are fixed to each other, and the air tube connector 10 and the air tube 30 are fixed to each other. When the user rotates the connector housing 50 to screw the valve core connector 20 onto the valve core 500, the inflation connector 10 and the connector housing 50 rotate relative to the air tube connector 10, while the air tube connector 10 and the air tube 30 remain stationary. With this configuration, the air tube 30 does not rotate with it and remains stationary as the user rotates the connector housing 50 to thread the valve core connector 20 onto the valve core 500, which facilitates quick threading of the valve core connector 20 onto the valve core 500.
