Referring to fig. 1 to 5, the present application provides a valve mounting structure 100, including a valve tube 10 and a base 20; the valve tube 10 has a plugged end 11; the base 20 is connected to the plugging end 11 of the valve tube 10, the base 20 comprises two connecting arms 21, the two connecting arms 21 are arranged at intervals along the radial direction of the valve tube 10, and each connecting arm 21 extends from the plugging end 11 in a direction away from the valve tube 10; each connecting arm 21 is provided with a connecting hole 2101. Specifically, the base 20 has a fixed supporting function on the valve tube 10, and the connecting arm 21 in the base 20 facilitates connecting the valve tube 10 with a to-be-connected component, so as to meet the requirement of the assembling condition of the valve tube 10. The two or more connecting arms 21 enable the valve tube 10 to have two or more supporting points when being installed with a to-be-connected component, and therefore stability of the valve tube 10 when being installed and connected with the to-be-connected component can be enhanced.

In a specific embodiment, the valve mounting structure 100 further includes a mounting member 30, the mounting member 30 is disposed through the two connecting arms 21, and one end of the mounting member 30 is configured with a locking cap 31, and the locking cap 31 abuts against the adjacent connecting arm 21. In practical use, the mounting plate can be arranged on the connecting piece, the mounting piece 30 penetrates through the mounting plate of the connecting piece and then penetrates through the connecting arm 21, at the moment, the mounting plate is tightly attached to the connecting arm 21, the locking cap 31 on the mounting piece 30 is tightly pressed on the mounting plate, or the mounting plate is tightly pressed between the locking cap 31 and the adjacent connecting arm 21, so that the connecting arm 21 is fixed relative to the mounting plate. Because the installation part 30 needs to penetrate through the two connecting arms 21, the two connecting arms 21 are matched with the installation part 30, the matching area and the supporting area of the connecting arms 21 and the installation part 30 are increased, the stability of the installation plate and the connecting arms 21 is further enhanced, and the condition that the installation part 30 is loosened is reduced.

In this embodiment, the mounting member 30 is a screw, and only the screw needs to be connected with the two connecting arms by threads, so that the operation is simple and the installation is convenient. In other embodiments, a nut may be disposed at an end of the screw away from the locking cap 31 for fixing, so as to enhance the fastening performance of the connection.

In this manner, the coupling protrusion 111 is provided to facilitate the contact coupling with the base 20, thereby achieving the coupling of the valve tube 10 with the base 20. Meanwhile, the distance between the two connecting arms 21 is short (certainly, the distance between the two connecting arms 21 cannot be too short, which should meet the supporting requirement of the valve tube 10), so that the length of the mounting part 30 is correspondingly short, and the production and processing of the mounting part 30 are facilitated; moreover, the mounting member 30 having a shorter length requires less support, and the mounting member 30 can be fixed only by providing a pair of connecting arms 21. Of course, as other embodiments, it is also possible to provide that the distance between the first and

second connection arms

211 and 212 is greater than the length of the connection projection 111 in the radial direction of the valve tube 10.

Specifically, the attachment hole 2101 on each attachment arm 21 is a threaded hole to facilitate the fitting of the mount 30. Two connecting arms 21 are worn to establish through connecting hole 2101 by two installed parts 30, because the axis that connecting hole 2101 on two connecting arms 21 corresponds is collinear, then installed part 30 can wear to establish simultaneously into two connecting arms 21, has increased the tie point between connecting arm 21 and other spare parts, and then has improved joint strength. Specifically, the two connecting holes 2101 on the two connecting arms 21 are spaced and uniformly distributed along the length direction of the connecting arms 21, so that the connecting arms 21 and other parts are uniformly stressed when being installed, and the structure of the connecting arms 21 is protected.

In other embodiments, three, four … … attachment holes 2101 are configured on each attachment arm 21, and multiple attachment holes 2101 are spaced apart along the length of the attachment arm 21.
