fig. 2 is an enlarged view of a portion a of fig. 1.
Detailed Description
The invention is further explained by combining the attached drawings.
Referring to fig. 1 and 2, the present invention provides a paint cup structure connected to a paint gun, including a paint cup 1 and a gun body 2, wherein the gun body 2 is provided with a threaded hole 3 connected to the paint cup 1, and the gun body 2 and the paint cup 1 are respectively provided with a gun body feed hole 4 and a cup body discharge hole 5 which are correspondingly communicated; a sealing mounting groove hole 6 is formed in the cup body discharging hole 5, a sealing movable frame 7 is arranged in the sealing mounting groove hole 6, and a material passing hole 8 for communicating the gun body feeding hole 4 with the cup body discharging hole 5 is formed in the sealing movable frame 7; an annular necking frustum 9 is arranged in the material passing hole 8, and the annular necking frustum 9 gradually shrinks from one end butted with the cup body discharging hole 5 to the direction of the gun body feeding hole 4;
when the paint cup is used, the paint in the paint cup 1 enters a gun body feeding hole 4 of a gun body through a cup body discharging hole 5 and a material passing hole 8, when the paint passes through the material passing hole 8, the section of the material passing hole 8 is reduced by an annular reducing frustum 9 in the material passing hole 8, so that the pressure for enabling a sealing movable frame 7 to move downwards is generated at the position of the annular reducing frustum 9 in the material passing hole 8 by the paint, and the end part of the sealing movable frame 7 abuts against the bottom end face of a threaded hole 3 to form abutting seal for the end parts of the gun body 2 and the paint cup 1; in order to ensure the sealing performance of the movable sealing frame 7 movably connected in the sealing installation slotted hole 6, a sealing ring 10 is arranged between the movable sealing frame 7 and the sealing installation slotted hole 6.
