Description

Novel anti-splashing and anti-spraying metal throat

Technical Field

The utility model relates to a vehicle field, in particular to novel prevent metal larynx that splashes, back flush.

Background

When the automobile is refueled, a fuel filling pipe arranged at the inlet of a fuel tank of the automobile needs to be used, the fuel filling pipe needs to be arranged into a proper structure to be arranged when in use, a throat opening for positioning is arranged at the end of the fuel filling pipe, and a fuel gun is used for filling fuel into the fuel filling pipe through the throat opening. And because the oil filling pipe, oil gun and the oil tank that both connect separately are sealed, then when carrying out the oiling, atmospheric pressure imbalance often can appear and cause the danger of damage to the oil tank structure, for this reason, then need set up the outside and be linked together and big enough gas outlet in the side of larynx mouth for guarantee the stability of the atmospheric pressure of refueling in-process.

In the common throat opening, only one strip-shaped air outlet is arranged on the side surface of the common throat opening, so that the air outlet quantity is ensured, but the air outlet has a certain width, so that oil is easy to splash out of the air outlet when being refueled; on the other hand, the throat comprises an access pipe with a larger size and a positioning pipe with a smaller size, and when the oil gun extends into the throat from the access pipe, the oil gun often collides with the positioning pipe, so that the oil gun or the throat is damaged. In addition, because the filler pipe is generally longer, often need set up corresponding structure in its a plurality of positions and fix simultaneously, just can stabilize the installation to it.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a novel prevent metal larynx that splashes, back-spray.

According to an aspect of the utility model, a novel prevent splashing, metal throat of back flush is provided, including a throat, the throat is including the pipe and the registration arm that let in that are linked together, the size that lets in the pipe is greater than the registration arm, and side on the registration arm is provided with a gas outlet, and the outside of gas outlet is equipped with the blend stop of slope.

The throat opening of the utility model is arranged on the oil injection pipe, and a plurality of fixing structures are arranged on the oil injection pipe, and a baffle strip is arranged outside the gas outlet of the throat opening at the end part of the throat opening, so that on one hand, the oil injection pipe can be stably arranged to ensure that the oil injection work is smoothly carried out; on the other hand, when refueling, not only guaranteed the air output, avoided the oiling pipe inside and outside to form the atmospheric pressure difference and cause oil to spill over, can play the effect that blocks to oil simultaneously, make it be difficult to follow gas outlet department spill.

In some embodiments, one end of the barrier strip is connected to the air outlet, and the other end of the barrier strip extends toward the inlet pipe. Therefore, the position and the shape of the barrier strip are set, and the oil splashing from the air outlet can be effectively blocked.

FIG. 2 is a second schematic view of the throat of FIG. 1;

FIG. 3 is a schematic view showing the structure in which the throat of FIG. 1 is attached to the filler pipe.

In the figure: the device comprises an oil injection pipe 1, a throat opening 2, an air outlet 3, an upper lifting ring 11, a lower fixing frame 12, a middle fixing frame 13, an inlet pipe 21, a positioning pipe 22, a thread line 23 and a blocking strip 31.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Fig. 1 schematically shows a structure of a novel splash-proof, back-spray metal throat according to an embodiment of the present invention, and fig. 2 shows another angle structure of the throat in fig. 1. As shown in fig. 1-2, the throat 2 mainly includes an access pipe 21 and a positioning pipe 22 which are integrally formed, wherein the access pipe 21 has a large size, and the positioning pipe 22 has a small size, wherein one end of the positioning pipe 22 can be attached to the filler pipe 1, and an oil gun can be inserted from the access pipe 21 and filled with oil. The overall length of the throat 2 from the end of the inlet pipe 21 to the end of the positioning pipe 22 is preferably in the range of 55mm to 75mm, which is suitable for most of the filler pipes 1, and the size of each specific part can be designed and selected according to actual conditions. Furthermore, to prevent erosion by oil, the throat 2 is preferably made of stainless steel or mild steel.

A thread 23 is integrally formed on the access pipe 21, and the thread 23 protrudes from the inside of the access pipe 21, so that the outside of the thread is in a groove shape on the access pipe 21; wherein the length of the thread 23 only has to be once around the lead-in pipe 21. When the oil gun is extended into the access pipe 21, the thread 23 can be mutually extruded with the oil gun from the periphery to play a certain sealing role, so that the oil can be prevented from overflowing from the pipe orifice of the access pipe 21 during oil injection.

The side surface of the positioning pipe 22 is provided with an air outlet 3, the air outlet 3 is approximately in a strip shape, and the length of the air outlet 3 is enough to ensure the air outlet quantity of the throat 2. And a barrier strip 31 is provided on the outside of the air outlet 3. Wherein, taking the air outlet 3 as a standard, the whole of the barrier strip 31 is inclined, one end of the barrier strip is connected with the air outlet 3, and the other end extends towards the direction of the inlet pipe 21 and gradually gets away from the air outlet 3 along with the extension of the barrier strip.

Fig. 3 shows a structure in which the throat of fig. 1 is attached to the filler pipe. As shown in fig. 3, the throat 2 may be mounted on the upper end of a filler pipe 1. The upper portion of the filler pipe 1 is inclined with a considerable inclination, and may be provided with some curvature as required. And an upper lifting ring 11 is arranged at the lower side of the upper part of the oil filling pipe 1, when the oil filling pipe 1 is held by hands, the hands can pass through the upper lifting ring 11, so that the holding is more stable, and certain protection effect can be achieved for the hands.

The filler pipe 1 is also inclined, but the inclination thereof is small and closer to horizontal. And the end of the lower part of the oil filling pipe 1 is provided with a lower fixing frame 12, wherein the middle part of the lower fixing frame 12 is provided with an invagination structure, and the two ends are in a horizontal plate shape, the end of the lower part of the oil filling pipe 1 can be arranged in the invagination structure, and the flat plates at the two ends are fixedly connected by using connecting pieces such as screws, and the end of the lower part of the oil filling pipe 1 can be fixedly installed.

In addition, can also set up a well mount 13 in the middle part of notes oil pipe 1, specifically for notes oil pipe 1 changes the comparatively gentle position of lower part department from the upper portion, can install the middle part of notes oil pipe 1 through well mount 13, can avoid because notes oil pipe 1 overlength and lead to the condition emergence that the middle part is tenesmic.

When using this notes oil pipe 1 and throat 2 to refuel, can align the lower extreme of notes oil pipe 1 with the oil tank of car, and use the oil gun to let in oil from throat 2 of the upper end of notes oil pipe 1, then oil can infuse the oil tank of vehicle smoothly through notes oil pipe 1, because gas outlet 3 and blend stop 31's existence, on the one hand, can guarantee the air output, avoid annotating oil pipe 1 inside and outside formation atmospheric pressure difference and cause oil to spill over, on the other hand, blend stop 31 also can play the effect that blocks up to oil, make it be difficult for following 3 spills of gas outlet more, thereby reduced the jam of oil, spill over and the condition such as splash.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
