Abstract
Description
Technical Field
[0001] This utility model relates to the field of engine technology, specifically to an oil pipe bracket. Background Technology
[0002] An engine is a machine that converts other forms of energy into mechanical energy and is widely used in transportation, industrial equipment and other fields.
[0003] Market research has revealed that, in order to facilitate fuel tank installation for users, most off-road vehicle manufacturers place fuel tanks on either side of the cab and below the engine in the overall vehicle structure.
[0004] In actual engineering applications, most vehicle manufacturers, considering costs, usually connect the fuel line directly to the fuel tank without raising it. This can easily increase the fuel pump's suction resistance and cause insufficient pressure. It can also easily allow air to get into the fuel line, creating air lock, which often makes the engine difficult to start. Based on this need, we developed this fuel line bracket structure. Utility Model Content
[0005] The purpose of this invention is to provide an oil pipe support to address the aforementioned shortcomings in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an oil pipe bracket, comprising a bracket body, the bracket body being fixedly installed on an engine intake pipe, the bracket body being L-shaped, and having a first limiting groove and a second limiting groove provided on the bracket body; an oil inlet pipe, which is fixedly disposed in the first limiting groove; and an oil return pipe, which is fixedly disposed in the second limiting groove, with protruding rings fixedly disposed at both ends of the oil inlet pipe and the oil return pipe.
[0007] Preferably, the bracket body has two mounting holes, and each mounting hole is provided with an anti-loosening bolt.
[0008] Preferably, two hose limit marks are provided on the outer peripheral surfaces of both the oil inlet pipe and the oil return pipe.
[0009] Preferably, two horizontal plates are fixedly installed at the bottom of the support body, each horizontal plate is rotatably equipped with a rotating rod, each rotating rod is fixedly equipped with a fixing block, and each fixing block is rotatably equipped with two first hoop rings.
[0010] Preferably, each of the horizontal plates is slidably provided with a slide rod, each of the slide rods is fixedly provided with a connecting plate, and each of the connecting plates is rotatably provided with two second hoop rings.
[0011] Preferably, both the first and second hoop rings are provided with locking bolts.
[0012] In the above technical solution, the present invention provides an oil pipe bracket, which has the following beneficial effects: by fixing the bracket body at a high position of the engine, the inlet and return oil pipes are raised, so that when the engine starts, the fuel pump inlet pipe can provide fuel in time, while the fuel stored in the return oil pipe prevents air from entering, which helps to improve the flow state of fuel in the oil pipe, forming a local low-pressure oil circuit arrangement, improving the engine starting ability. At the same time, the cooperation of the convex ring, the first clamp ring, and the second clamp ring can make the hose stably connected to the inlet and return oil pipes, preventing the hose from falling off.

Detailed Implementation
[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0022] Please see Figure 1-5 An oil pipe bracket, the technical solution proposed in this utility model, includes a bracket body 1, which is fixedly installed on the engine intake pipe. The bracket body 1 is L-shaped and has a first limiting groove 4 and a second limiting groove 5. An oil inlet pipe 6 is fixedly installed in the first limiting groove 4. An oil return pipe 7 is fixedly installed in the second limiting groove 5. Both ends of the oil inlet pipe 6 and the oil return pipe 7 are fixedly provided with protruding rings 8. Since the intake pipe is located high in the engine structure, and the intake pipe is usually connected to the engine via a flange, the bracket body 1 is installed on this flange during use. The long arm end of the L-shaped bracket body 1 is fixedly connected to the flange. An arc groove 2 adapted to the intake pipe is opened on the bracket body 1. The first limiting groove 4 and the second limiting groove 5 are located on the short arm end of the bracket body 1. The oil inlet pipe 6 is welded into the first limiting groove 4. The return oil pipe 7 is welded into the second limiting groove 5. The first limiting groove 4 and the second limiting groove 5 facilitate the welding of the inlet oil pipe 6 and the return oil pipe 7. One end of the inlet oil pipe 6 and the return oil pipe 7 are connected to the fuel tank and other devices through a rubber hose, and the other end is connected to the engine and other devices through a rubber hose. That is, the inlet oil pipe 6 and the return oil pipe 7 are set between the engine and the fuel tank. The convex ring 8 can prevent the rubber hose from falling off. The height of the inlet oil pipe and the return oil pipe is raised by the bracket body 1, which can reduce the oil suction resistance and promote the accumulation of air bubbles towards the fuel tank, reducing air resistance interference. When the engine starts, the fuel pump inlet pipe provides fuel in time, and the fuel stored in the fuel pump return pipe seals the air, which helps to improve the flow state of fuel in the fuel pipe and form a local low-pressure fuel circuit arrangement, thereby improving the fuel supply efficiency, reducing the starting delay of the whole vehicle, and improving the engine starting ability.
[0023] Specifically, the bracket body 1 has two mounting holes 3, and each mounting hole 3 is equipped with an anti-loosening bolt 10; the flange has a threaded groove that matches the anti-loosening bolt 10. The two mounting holes 3 are located on the long arm end of the bracket body 1. The bracket body 1 and the flange are connected together by the anti-loosening bolt 10, thereby fixing the bracket body 1 at the high position of the engine. The anti-loosening bolt 10 can reduce the loosening of the connection caused by engine vibration.
[0024] Specifically, two hose limit marks 9 are provided on the outer circumference of both the oil inlet pipe 6 and the oil return pipe 7; for example Figure 3 As shown, the hose limit mark 9 is engraved on both ends of the oil inlet pipe 6 and the oil return pipe 7 and is a certain distance away from the convex ring 8. The hose limit mark 9 facilitates the control of the hose insertion depth. The bracket body 1 is made of steel plate and is manufactured by stamping process.
[0025] Specifically, two horizontal plates 11 are fixedly installed at the bottom of the bracket body 1. Each horizontal plate 11 has a rotating rod 12 rotatably mounted on it. Each rotating rod 12 has a fixed block 13 fixedly mounted on it, and each fixed block 13 has two first hoop rings 14 rotatably mounted on it. In the initial state, the two first hoop rings 14 are open, the rotating rods 12 are perpendicular to the horizontal plates 11, and the two horizontal plates 11 are respectively fixed on the side away from the oil inlet pipe 6 of the first limiting groove 4 and the second limiting groove 5. Both the oil inlet pipe 6 and the oil return pipe 7 are L-shaped bends. The long arms of the oil inlet pipe 6 and the oil return pipe 7 are welded to the bracket body 1. During installation, the two ends of the oil inlet pipe 6 and the oil return pipe 7 are respectively inserted into the oil inlet hose connected to the engine and the fuel tank. At the end of the oil hose, the convex ring 8 is tightly abutted against the inner wall of the hose to prevent fuel leakage from the convex ring 8. During installation, align each hose with the corresponding hose limit mark 9, and then rotate the rotating rod 12 parallel to the horizontal plate 11. At this time, each first hoop 14 is on the side of the convex ring 8 close to the bracket body 1. The ends of the oil inlet pipe 6 and oil return pipe 7 with the hose are between the corresponding two first hoop 14. Then, close each first hoop 14 and tighten them together. The hose is tightly attached to the ends of the oil inlet pipe 6 and oil return pipe 7 through the first hoop 14, and the outer circumference of the hose is squeezed and deformed, so that the hose cannot fall off from the ends of the oil inlet pipe 6 and oil return pipe 7 through the convex ring 8.
[0026] Specifically, each slide rod 16 is slidably mounted on the slide rod 16, and a connecting plate 17 is fixedly mounted on each slide rod 16. Two second hoop rings 18 are rotatably mounted on each connecting plate 17. In the initial state, the horizontal plate 11 of the slide rod 16 is close to the rotating rod 12. At this time, the second hoop rings 18 are open. When the hose is sleeved on the short arm end of the oil inlet pipe 6 and the oil return pipe 7, each slide rod 16 is moved to the end of the horizontal plate 11 away from the rotating rod 12. At this time, the short arm end of the oil inlet pipe 6 and the oil return pipe 7 is between the corresponding second hoop rings 18. Then, each second hoop ring 18 is rotated to tighten the short arm end of the oil inlet pipe 6 and the oil return pipe 7, thereby preventing the hose from falling off from the short arm end of the oil inlet pipe 6 and the oil return pipe 7.
[0027] Specifically, both the first hoop 14 and the second hoop 18 are provided with locking bolts 15; one of the first hoop 14 on the same horizontal plate 11 is provided with a locking bolt 15, and the other first hoop 14 is fixedly provided with a nut. Similarly, one of the two second hoops 18 on the same horizontal plate 11 is connected to the locking bolt 15, and the other is fixedly provided with a nut that matches the locking bolt 15. When the first hoop 14 and the second hoop 18 are closed, the locking bolt 15 is rotated to make it tightly clamp onto the hose, thereby preventing the hose from falling off.
[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
