Description

Technical Field

[0001] This utility model belongs to the field of oil tanker metal pipe connection technology, specifically relating to a connection structure for oil tanker metal pipes. Background Technology

[0002] A gasoline vehicle is a car that uses fuel as its power source, mainly including gasoline cars and diesel cars. Gasoline cars use fuel engines to burn fuel to generate power to drive the vehicle. The fuel line is the pipeline system in a gasoline car used to transport fuel from the fuel tank to the engine combustion chamber. It plays the role of guiding fuel from the fuel tank to the engine, ensuring that the fuel can reach the combustion chamber through the appropriate path to meet the needs of engine combustion and operation.

[0003] In the process of using existing automotive oil lines, two oil lines need to be connected by a connection structure. The existing connection method is generally to use a threaded rotation method. However, when the car is in motion, the engine will be running. The engine will generate severe vibration and impact during operation. The vibration will be transmitted to the oil lines, causing the connection to loosen and resulting in oil leakage. Utility Model Content

[0004] The purpose of this utility model is to provide a simple and reasonably designed connection structure for metal pipe fittings in oil tankers in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A connection structure for a metal pipe fitting in an oil tanker includes two oil pipes and a connecting sleeve. A connecting pipe is installed at one end of each of the two oil pipes that are close to each other. Both connecting pipes are screwed into the connecting sleeve and located at both ends of the connecting sleeve. An annular retaining plate is installed on the outside of each of the two connecting pipes. Two arc-shaped plates are provided on the outside of the connecting sleeve, forming a cylindrical structure between them. The two arc-shaped plates are connected by a fixing mechanism. Each of the two arc-shaped plates has a slot and two retaining grooves on one side that are close to each other, which cooperate with the connecting sleeve. The two retaining grooves are located on both sides of the slot and cooperate with the annular retaining plate.

[0007] As a further optimization of this utility model, the connecting pipe is provided with an external thread on its exterior, and the inner wall of the connecting sleeve is provided with an internal thread that mates with the external thread.

[0008] As a further optimization of this utility model, the fixing mechanism includes a first fixing plate installed on both sides of one of the arc-shaped plates and a second fixing plate installed on both sides of the other arc-shaped plate. The corresponding first fixing plate and second fixing plate are connected by multiple fixing components. The fixing components include a screw and a nut that cooperates with the screw, as well as fixing holes opened on the first fixing plate and the second fixing plate.

[0009] As a further optimization of this utility model, sealing strips are installed on the inner walls of both sides of the slot, and one side of each sealing strip is respectively attached to the two sides of the connecting sleeve.

[0010] As a further optimization of this utility model, strip plates are installed at the top and bottom of the connecting sleeve, and a strip groove is formed on the inner wall of the slot to cooperate with the strip plates.

[0011] As a further optimization of this utility model, the top and bottom of the annular card plate are provided with limiting holes, and the inside of the card slot is equipped with a limiting rod that cooperates with the limiting holes.

[0012] The beneficial effects of this utility model are as follows: When the two arc-shaped plates are fixed during use, the two oil pipes can be locked, reducing the possibility of the two oil pipes coming apart. In addition, the loosening of the connection structure caused by the rotation between the connecting sleeve and the connecting pipe can be reduced, making it more convenient for people to use.

[0019] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] like Figures 1-5 As shown, a connection structure for a metal pipe fitting of an oil truck includes two oil pipes 1 and a connecting sleeve 3. A connecting pipe 4 is installed at one end of each oil pipe 1 that is close to each other. The two connecting pipes 4 are screwed into the connecting sleeve 3 and located at both ends of the connecting sleeve 3. An annular clamping plate 5 is installed on the outside of each connecting pipe 4. Two arc-shaped plates 2 are provided on the outside of the connecting sleeve 3, forming a cylindrical structure between the two arc-shaped plates 2. The two arc-shaped plates 2 are connected by a fixing mechanism. A groove 8 and two slots 9 are provided on one side of each arc-shaped plate 2 that are close to each other and are used to cooperate with the connecting sleeve 3. The two slots 9 are located on both sides of the groove 8 and are used to cooperate with the annular clamping plate 5. The outside of the connecting pipe 4 is provided with an external thread, and the inner wall of the connecting sleeve 3 is provided with an internal thread that is used to cooperate with the external thread.

[0021] The fixing mechanism includes a first fixing plate 7 installed on both sides of one of the arc plates 2, and a second fixing plate 15 installed on both sides of the other arc plate 2. The corresponding first fixing plate 7 and second fixing plate 15 are connected by multiple fixing components. The fixing components include a screw 16 and a nut 17 that cooperates with the screw 16, and fixing holes 10 opened on the first fixing plate 7 and the second fixing plate 15.

[0022] Sealing strips 14 are installed on both inner walls of the slot 8. One side of each sealing strip 14 is attached to the two sides of the connecting sleeve 3. When the connecting sleeve 3 is inside the slot 8, one side of the sealing strip 14 will seal the connection between the connecting sleeve 3 and the oil pipe 1, thereby reducing leakage and improving the sealing performance of the connection structure.

[0023] The top and bottom of the connecting sleeve 3 are both equipped with strip plates 6. The inner wall of the slot 8 is provided with a strip groove 13 that works with the strip plate 6. The top and bottom of the annular retaining plate 5 are both provided with limiting holes 11. The inside of the retaining groove 9 is equipped with a limiting rod 12 that works with the limiting hole 11. When the strip plate 6 is inside the strip groove 13, it can prevent the connecting sleeve 3 from rotating. Similarly, when the limiting rod 12 is inside the limiting hole 11, it can prevent the oil pipe 1 from rotating. This can reduce the possibility of the connecting sleeve 3 and the connecting pipe 4 becoming loose due to rotation.

[0024] It should be noted that, in the use of this type of metal pipe fitting connection structure, the two connecting pipes 4 are screwed into the inside of the connecting sleeve 3 from both ends. After screwing, the two arc plates 2 are joined together, forming a cylinder. At this time, the two annular clamping plates 5 installed outside the two oil pipes 1 are located in the two clamping slots 9 on both sides of the groove 8, which can lock the two oil pipes 1 and prevent them from detaching. The strip plate 6 is located in the strip groove 13, the limiting rod 12 is located in the limiting hole 11, and the connecting sleeve 3 is located in the groove 8. Then, the screw is screwed into the two fixing holes 10 corresponding to the first fixing plate 7 and the second fixing plate 15. After screwing, the nut 17 is screwed onto the outside of the screw 16 and locked by the nut 17. When the screw 16 is screwed into multiple fixing holes 10, the installation is completed.

[0025] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
