Embodiment approach 1

[0040] The first embodiment of the present invention provides a fuel gun with a vacuum cap assembly installed, see figure 1 , figure 2 , image 3 , Figure 6 , Figure 7 and Figure 8 As shown, the vacuum cap assembly 1 includes a self-sealing assembly 2 and a jumper device 3. In this embodiment, the jumper device 3 is composed of a self-sealing reset block 3a, a self-sealing spring 3b, a base 3c, a jumper spring 3d, The diaphragm assembly 3e, the needle roller 3f and the needle roller handle 3g are connected by a connecting piece 3h. The self-styled spring 3b and the jumper spring 3d act independently, the two ends of the self-styled spring 3b are respectively connected to the base 3c and the self-styled reset block 3a, and the two ends of the jumper spring 3d are respectively connected to the base 3c and the diaphragm assembly 3e. In addition, sealing rings are provided at the positions where the components are connected and need to be sealed.

[0041] Moreover, in th...

Embodiment approach 2

[0049] The second embodiment of the present invention provides a fuel gun 7, this embodiment is a further improvement on the first embodiment, the main improvement is that in this embodiment, see figure 1 and figure 2 As shown; the vacuum chamber 3i is connected to the vacuum channel 4, and the vacuum chamber 3i is formed as a space area from the top of the diaphragm assembly 3e to the bottom of the self-sealing piston 2b1.

[0050] The base 3c includes a base lower cover 3c3. The base 3c also includes a base lower cover 3c3 flange spring seat 3c2. The flange spring seat 3c2 is fixed on the inner side wall of the cylindrical part 3c2, one side of the flange spring seat 3c2 is fixedly connected to one end of the self-sealing spring 3b, the opposite side is fixedly connected to one end of the jumper spring 3d, and the other end of the self-sealing spring 3b One end is connected to the self-styled reset block 3a, and the other end of the jumper spring 3d is connected to the di...

Embodiment approach 3

[0061] The third embodiment of the present invention provides a fuel gun 7, this embodiment is a further improvement on the first or second embodiment, the main improvement is that, see Figure 6 As shown, positioning grooves 3c21 are respectively provided on the surface of the flange spring seat 3c2 connecting the self-sealing spring 3b and the jumper spring 3d.

[0062] Specifically, the positioning groove 3c21 is correspondingly arranged on the surface of the flange spring seat 3c2, which can further fix the positions of the self-sealing spring 3b and the jumper spring 3d in the vacuum cap assembly 1, and reduce the relative distance between the spring and the flange spring seat 3c2. move to prevent the spring from detaching from the flange base 3c, thereby improving the reliability of the vacuum cap assembly 1 .

Abstract

The invention relates to the technical field of fuel oil filling and oil gas recycling, in particular to an oil filling gun. The oil filling gun is internally provided with a vacuum cap component, thevacuum cap component comprises a self-sealing component and a gun jumping device, wherein the gun jumping device comprises a self-sealing reset block, a self-sealing spring, a base seat, a gun jumping spring, a diaphragm component, a rolling needle and a rolling needle lifting handle and is connected through a connection part, the base seat is fixed inside a cavity body of the oil filling gun, the self-sealing spring and the gun jumping spring act on the base seat independently, the two ends of the self-sealing spring are connected to the base seat and the self-sealing reset block correspondingly, and the two ends of the gun jumping spring are connected to the base seat and the diaphragm component correspondingly. According to the oil filling gun provided by the invention, stress of the self-sealing spring and the stress of the gun jumping spring are both absorbed by the base seat and the base seat is fixedly installed inside the oil filling gun, so that mutual interference between the gun jumping spring and the self-sealing spring is prevented, reduction of unnecessary gun jumping is facilitated, and the reliability of the oil filling gun is greatly improved.

Description

technical field [0001] The invention relates to the field of fuel filling, in particular to a fueling gun and fueling equipment. Background technique [0002] Specifically, the vacuum cap assembly includes a self-sealing assembly and a jumper device, etc. The self-sealing assembly can open the oil valve by adjusting the needle roller in the vacuum cap assembly to engage with the main shaft. The gun jumping device can choose whether to jump the gun according to the vacuum degree, so as to ensure the safety of use. Both the self-styled component and the jumper device are provided with springs, and the movement of the self-styled component and the jumper device can only be realized by relying on the spring. [0003] For example, in the refueling gun provided in the prior art, the spring of the self-sealing assembly and the spring of the jumper device act together on the self-sealing reset block. When the oil pressure of the refueling gun decreases, the force on the spring of ...
