Description

Technical Field

[0001] The utility model relates to a refueling machine, in particular to a high-sealing refueling machine. Background Art

[0002] A gas station is a place where cars add fuel. It is mainly composed of three parts: an underground oil storage tank, a refueling column and a management room. Its main task is to store, preserve and supply fuel and lubricants for automobiles.

[0003] The refueling route for a car is from the oil tank through the oil pipeline, oil pump, oil gun and other components to the vehicle tank. After refueling, the oil gun will be put back into the storage tank on the body. At this time, if gasoline still remains on the oil gun, it may drip onto the storage tank of the body during storage and then escape into the air: 1. Not only will it cause energy waste, but the mixture of oil and gas and air will easily form an explosive mixture, posing a major safety hazard to gas stations and the surrounding environment; 2. Oil and gas leakage is not only prone to fire and explosion accidents, but its volatiles are also potentially harmful to human health, such as irritation to the eyes and respiratory tract. Long-term contact may cause skin allergies and nervous system damage. A good refueling port seal can prevent operators from direct contact with oil and gas, ensuring their occupational health and safety.

[0004] Therefore, how to prevent the oil gas remaining on the surface of the oil gun from flowing out of the body and entering the outside after the oil gun is placed in the storage tank has become an urgent problem to be solved by those skilled in the art. Summary of the invention

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a high-seal fuel dispenser in which the oil and gas remaining in the spray gun after being loaded into the storage tank cannot flow out of the body beyond the second sealing ring.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: it consists of a machine body, a refueling pipe and a spray gun, the length direction of the machine body extends up and down, one end of the refueling pipe is fixed to the spray gun and the other end is fixed to the machine body, a storage groove for the spray gun is provided on the left side of the machine body and a cover plate is provided on the left side of the storage groove, a socket for the spray gun is provided on the cover plate, a first sealing ring is provided on the circumference of the refueling pipe, a second sealing ring is provided on the cover plate on the socket, and a positioning groove with a shape and size adapted to the first sealing ring is provided on the second sealing ring.

[0007] The utility model is further configured as follows: the first sealing ring is arranged in a stepped shape from left to right and narrowed from top to bottom.

[0008] The utility model is further configured as follows: it also includes a plurality of bolts, the cover plate is provided with a plurality of through holes, the body is provided with screw holes corresponding to the through holes, each of the bolts is inserted into one of the through holes and matched with the corresponding screw hole thread.

[0009] The utility model is further configured as follows: it also includes a lower hook, which is fixedly connected to the machine body, and the lower hook includes a lower fixed section and a lower limit section, the lower fixed section is fixedly connected to the machine body and extends left and right in length, and the lower limit section is located above the lower fixed section and is perpendicular to the lower fixed section in length.

[0010] The utility model is further configured as follows: it also includes an upper hook, the upper hook includes an upper fixed section and an upper limit section, the length direction of the upper fixed section extends left and right and is rotatably installed on the machine body, the upper limit section is located above the lower limit section and is against the lower limit section, and the upper limit section and the lower limit section are detachably connected.

[0011] The utility model is further configured as follows: an upper magnet is arranged on the upper limit segment, and a lower magnet is arranged on the lower limit segment.

[0012] The utility model is further configured as follows: the upper limit segment is arranged to be inclined from left to right from top to bottom, and the lower limit segment is arranged to be inclined from right to left from top to bottom.

[0013] By adopting the above technical scheme, since there is a first sealing ring on the circumference of the refueling pipe, when the spray gun is installed in the storage tank, the first sealing ring cooperates with the second sealing ring, and the first sealing ring is located in the positioning groove, so the oil and gas remaining on the spray gun can drip downward into the storage tank, but if the oil and gas in the storage tank flows outward, it can be restricted by the first sealing ring and the second sealing ring and cannot flow out of the body, so as to avoid the oil and gas escaping into the air to cause energy waste, and mixing with air to form an explosive mixture, which poses a major safety hazard to the gas station and the surrounding environment, and reduce the fire outbreak accidents caused by oil and gas leakage.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1-Figure 6As shown, the utility model discloses a high-seal fuel dispenser, which is composed of a body 1, a fueling pipe 2 and a spray gun 3. The length direction of the body 1 extends up and down, one end of the fueling pipe 2 is fixed to the spray gun 3 and the other end is fixed to the body 1. During the fueling process of the fuel dispenser, the oil is transported from the oil tank to the vehicle tank via the oil pipeline, the oil pump, the oil gun and other components (this is the prior art and will not be elaborated on here). A storage groove 11 for the spray gun 3 to be placed is arranged on the left side of the body 1, and a cover plate 12 is arranged on the left side of the storage groove 11, and a plug hole 121 for the spray gun 3 to be inserted is arranged on the cover plate 12. A first sealing ring 21 is arranged circumferentially on the fueling pipe 2, and a second sealing ring 123 is arranged on the cover plate 12 on the plug hole 121, and a shape and size of the first sealing ring are arranged on the second sealing ring 123 The first sealing ring 21 is adapted to the positioning groove 1231. Since there is a first sealing ring 21 on the circumference of the refueling pipe 2, when the spray gun 3 is installed in the storage groove 11, the first sealing ring 21 cooperates with the second sealing ring 123, and the first sealing ring 21 is located in the positioning groove 1231. Therefore, the oil and gas remaining on the spray gun 3 can drip downward into the storage groove 11, but if the oil and gas in the storage groove 11 flows outward, it can be restricted by the double-layer shielding of the first sealing ring 21 and the second sealing ring 123 and cannot flow out of the body 1, thereby improving the sealing of the body 1 in the storage groove 11, so as to avoid the oil and gas escaping into the air and causing energy waste, and mixing with air to form an explosive mixture, which poses a major safety hazard to the gas station and the surrounding environment, and reduce the fire outbreak accidents caused by oil and gas leakage.

[0028] Preferably, the first sealing ring 21 is arranged in a stepped shape from left to right and narrowed from top to bottom. 1. Since the first sealing ring 21 is arranged in a narrowed shape from left to right, and the positioning groove 1231 on the second sealing ring 123 is adapted to the shape of the first sealing ring 21, after the spray gun 3 is placed in the storage groove 11, if the oil and gas flow outward from the storage groove 11, it will first be blocked by the right end face of the second sealing ring 123 with a larger width. If the oil and gas pass over the right end face of the second sealing ring 123, it also needs to pass over the first sealing ring 21. 1. The left side of the sealing ring 21 can flow to the outside of the body 1, thereby improving the sealing of the storage groove 11; 2. Since the right side of the first sealing ring 21 has the smallest width, and the left side of the second sealing ring 123 located at the positioning groove 1231 has the largest width, therefore, when the spray gun 3 is placed into the storage groove 11, the rightmost side of the first sealing ring 21 on the refueling pipe 2 will first enter the leftmost side of the second sealing ring 123, thereby allowing the first sealing ring 21 to enter the positioning groove 1231 more smoothly and thus achieve cooperation with the second sealing ring 123.

[0029] It also includes a number of bolts (not shown in the figure), the cover plate 12 is provided with a number of through holes 122, the body 1 is provided with screw holes 14 corresponding to each through hole 122, each of the bolts is inserted into one of the through holes 122 and threadedly matched with the corresponding screw hole 14. Since the cover plate 12 and the body 1 are detachably connected by bolts, if the second sealing ring 123 is worn during use and the second sealing ring 123 needs to be cleaned, the second sealing ring 123 can be accessed and cleaned by removing the cover plate 12 from the body 1. If the second sealing ring 123 needs to be replaced, it can be achieved by directly replacing the cover plate 12 without disassembling the entire body 1, thereby providing convenience for replacing and repairing the second sealing ring 123.

[0030] Among them, it also includes a lower hook 4, which is fixedly connected to the body 1, and the lower hook 4 includes a lower fixed section 41 and a lower limit section 42. The lower fixed section 41 is fixedly connected to the body 1 by welding or the like and extends left and right in length. The lower limit section 42 is located above the lower fixed section 41 and is perpendicular to the lower fixed section 41 in length. Since the lower hook 4 includes the lower limit section 42 and the lower fixed section 41, and the lower limit section 42 is located above the lower fixed section 41, when the refueling pipe 2 needs to be stored, it can be wrapped around the refueling pipe 2 so that the part of the refueling pipe 2 located above the lower fixed section 41 can be blocked by the limit section to the left, so that it can be stably located on the lower limit section 42 without the action of external force.

[0031] In addition, it also includes an upper hook 5, which includes an upper fixed section 51 and an upper limit section 52. The length direction of the upper fixed section 51 extends left and right and is rotatably installed on the body 1, and the upper limit section 52 is located above the lower limit section 42 and is against the lower limit section 42. Since the upper limit section 52 of the upper hook 5 is located above the lower limit section 42, and the upper fixed section 51 is rotatably installed on the body 1, the upper limit section 52 and the lower limit section 42 are detachably connected by Velcro, magnetic suction, etc. Therefore, under the action of gravity, the upper limit section 52 can be against the lower limit section 42, so that the part of the refueling pipe 2 wrapped around the lower limit section 42 can be stably located between the upper limit section 52 and the lower limit section 42, so that the refueling pipe 2 can be easily hung on the body 1, which is convenient for the operator to quickly take and put during the refueling process, improve work efficiency, and avoid safety hazards caused by random placement. At the same time, a stable support point is provided for the refueling pipe 2 during the refueling process. This structural design allows the refueling pipe 2 to remain stable during the refueling process, avoiding oil leakage caused by shaking or accidental collision, and improving the safety of the refueling operation.

[0032] Preferably, an upper magnet 521 is provided on the upper limit segment 52, and a lower magnet 421 is provided on the lower limit segment 42. The upper limit segment 52 and the lower limit segment 42 of the upper hook 5 are detachably connected through the mutual attraction of the upper magnet 521 and the lower magnet 421. This magnetic design not only ensures the stability of the refueling pipe 2 and the spray gun 3 in the hanging state to prevent accidental falling off, but also allows the operator to easily remove the spray gun 3 and the refueling pipe 2 when needed, which is easy to operate and improves the convenience of using the refueling pump.

[0033] Preferably, the upper limit segment 52 is inclined from left to right from top to bottom, and the lower limit segment 42 is inclined from right to left from top to bottom. In addition to wrapping the refueling pipe 2 and placing it on the lower fixed segment 41, the spray gun 3 can be temporarily placed on the lower fixed segment 41 during operation. At this time, the upper limit segment 52 and the lower limit segment 42 are inclined from left to right and from right to left respectively, forming an anti-accidental touch structure. This design can cleverly cover the trigger part of the spray gun 3, avoid accidental splashing or leakage of oil due to accidental touching of the trigger, and enhance the safety of the refueling operation.
