Detailed Description

To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the embodiments of the present invention are combined to clearly and completely describe the technical solution in the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 and fig. 2, the present embodiment provides a quick assembling tool for a wheel valve core, which includes an operating rod 1, a pilot pin 2, and a hook connector 3. In this embodiment, action bars 1 adopts the tubular metal resonator preparation, guarantees that intensity accords with the operation demand. The pilot pin 2 is perpendicular to the operating rod 1 and fixed at the end of the operating rod 1, and the top end of the pilot pin 2 is pointed and aims to be matched with an air inlet hole of the valve core 4. The pilot pin and the operating rod 1 can be fixed by welding. However, in order to adjust the height of the pilot pin 2 to adapt to hubs with different sizes, the embodiment adopts the mode that the end part of the operating rod 1 is provided with the mounting hole, the pilot pin 2 is provided with an external thread and penetrates through the mounting hole, then the pilot pin is fixed through the locking nut, and the height of the pilot pin 2 can be adjusted as required.

The hook head connecting piece 3 comprises a connecting plate 31 and a protective layer; one end of the connecting plate 31 is a rotating end and is fixed to the operating rod 1 in a rotating manner. The other end is a hook-shaped piece, and the protective layer is fixed with the hook-shaped piece and is contacted with the hub. The rotation fixing mode of the connecting plate 31 and the operating rod 1 is specifically as follows: the operating rod 1 is provided with a long hole 11 short of the mounting hole, the direction of the long hole 11 is consistent with that of the mounting hole, and the rotating end of the connecting plate 31 is located in the long hole 11 and then fixed through the rotating shaft. The length of the elongated hole 11 satisfies the rotation range of the hook head connecting piece 3, and the hook head connecting piece 3 can be matched with the hub. The hook head connecting protective layer comprises two hook-shaped plates 32 which are respectively fixed on two sides of the hook-shaped piece, one side of the hook-shaped plate 32 facing the hub exceeds the hook-shaped piece, the protective layer is generally made of nylon materials or rubber materials and directly contacts with the hub 5, and the protective layer can bear communication tension and protect the appearance of the hub 5 from being damaged.
