[0002] A pipeline is a device made up of pipes, pipe fittings, valves, etc., used to transport gases, liquids, or fluids containing solid particles.
[0003] In existing pipelines, flanges are typically installed at the ends of the pipes, and two flanges are connected together using multiple bolts, thus connecting the ends of the two pipes together.
[0004] While the above-mentioned pipe connection method can connect two pipes together, it becomes quite cumbersome if the pipes are long and multiple bolts are needed to fix each two pipe sections. Therefore, a pipe connection structure that is faster and has more stable connection strength is needed. Summary of the Invention
[0005] In view of this, the present invention provides a fuel pipeline connection structure resistant to alcohol corrosion. The present invention can quickly connect the ends of two pipelines together and ensure the connection strength of the two pipelines.
[0006] To solve the above-mentioned technical problems, this utility model provides a fuel pipeline connection structure resistant to alcohol corrosion, including a fixing member disposed at one end of the pipeline, and a movable member disposed at the other end of the pipeline corresponding to the fixing member, wherein the fixing member can be connected to the movable member.
[0007] The fastener includes a fixed pipe installed at one end of the pipe, a storage groove inside the fixed pipe, the storage groove being located at the end of the fixed pipe away from the pipe, a thread on the outside of the fixed pipe, and a rotating ring installed on the outside of the fixed pipe via a bearing, the rotating ring being able to rotate on the outside of the fixed pipe, and several threaded rods being hinged on the rotating ring, with nuts on the threaded rods, the nuts and threaded rods being threadedly engaged.
[0008] The movable component includes a positioning ring at the other end of the pipe, which can be inserted into the placement groove.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to Figures 1-4. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the scope of protection of this utility model.
[0025] As shown in Figures 1-4: It includes a fixing member 100 set at one end of the pipe, and a movable member 200 is provided at the other end of the pipe corresponding to the fixing member 100. The fixing member 100 and the movable member 200 can be quickly connected together. When the fixing member 100 and the movable member 200 are connected together, the ends of the two pipes can be connected together.
[0026] The fastener 100 includes a fixed tube 101 disposed at one end of the pipe. The fixed tube 101 is coaxially disposed with the pipe. A storage groove 102 is provided at the end of the fixed tube 101 away from the pipe. The storage groove 102 is used to place a positioning ring 201. The outside of the fixed tube 101 is also provided with threads. A rotating ring 103 is also provided on the outside of the fixed tube 101 through a bearing. The rotating ring 103 can rotate on the outer wall of the fixed tube 101. Several lead screws 104 are hinged on the rotating ring 103. In this embodiment, there are four lead screws 104, which are arranged in a ring array on the rotating ring 103. Each lead screw 104 is provided with a nut 105. The nuts 105 can rotate on the lead screw 104. The rotation of the nuts 105 on the lead screw 104 allows them to move left and right on the outside of the lead screw 104.
[0027] The movable component 200 includes a positioning ring 201 disposed at the other end of the pipe. The positioning ring 201 is coaxially disposed with the pipe. A movable ring 202 is also slidably disposed on the pipe corresponding to the positioning ring 201. The movable ring 202 can move left and right on the pipe. A threaded hole 203 is provided in the movable ring 202 corresponding to the thread on the outside of the fixed pipe 101. After the movable ring 202 moves to the outside of the fixed pipe 101, it rotates until the fixed pipe 101 is located in the threaded hole 203 on the movable ring 202. A number of positioning blocks 204 are also provided on the outside of the movable ring 202 corresponding to the lead screw 104. In this embodiment, there are also 4 positioning blocks 204, which are arranged in a ring array on the outer wall of the movable ring 202. A relief groove 205 is provided on the positioning block 204 corresponding to the lead screw 104. In this embodiment, the relief groove 205 is a U-shaped structure and is disposed through the positioning block 204. After the lead screw 104 rotates, it can be screwed into the relief groove 205 on the positioning block 204.
[0028] When connecting the pipes, the two pipes are placed coaxially and abutted together, allowing the positioning ring 201 on the movable part 200 to insert into the storage groove 102 on the fixed pipe 101 until the positioning ring 201 abuts against the side wall of the storage groove 102. Then, the movable ring 202 is slid to the end of the fixed pipe 101 and rotated. After the movable ring 202 rotates to the outside of the fixed pipe 101, the rotating ring 103 is rotated, causing the lead screw 104 to rotate to the position corresponding to the positioning block 204. Then, the lead screw 104 is rotated until it rotates into the positioning block 204. The screw 104 is inserted into the clearance groove 205, and then the nut 105 on the screw 104 is rotated. The nut 105 rotates and moves toward the rotating ring 103 until the nut 105 abuts against the side wall of the positioning block 204, thereby limiting the screw 104. The screw 104 will not rotate on the rotating ring 103, which indirectly limits the rotating ring 103 and the fixed pipe 101. That is, the distance between the fixed pipe 101 and the movable ring 202 will not be increased, thereby realizing the connection between the fixed part 100 and the movable part 200, so that the ends of the two pipes can be connected together.
[0029] As shown in Figures 1 and 4
[0030] The positioning ring 201 and the storage groove 102 are both conical frustum structures and are matched in size and shape. That is, after the positioning ring 201 is inserted into the storage groove 102, the outer surface of the positioning ring 201 can fit into the storage groove 102, so there will be no gap between the two pipes, and the liquid or solid material transported in the pipe will not leak out from the pipe connection.
[0031] As shown in Figures 1 and 4
[0032] Both the positioning ring 201 and the fixing tube 101 are made of rubber. Using rubber not only increases the friction between the positioning ring 201 and the fixing tube 101, meaning that the positioning ring 201 can fit more closely to the storage groove 102, but also prevents the fixing part 100 or the moving part 200 from being damaged by hard collision when the two pipes are connected and installed.
[0033] As shown in Figure 4
[0034] A retaining ring 206 is also provided on the outside of the positioning ring 201. The retaining ring 206 is located on the end of the positioning ring 201 that is close to the pipe. Corresponding to the retaining ring 206, a limiting ring 207 is provided on the end of the movable ring 202 that is away from the fixed pipe 101. That is, the limiting ring 207 and the retaining ring 206 cooperate to prevent the movable ring 202 from falling off the pipe. When connecting the fixed part 100 and the movable part 200, the movable ring 202 should be rotated until the limiting ring 207 abuts against the retaining ring 206 to stop the rotation of the movable ring 202, and then the screw 104 should be rotated.
[0035] As shown in Figure 2,
[0036] The nut 105 is also provided with a force-applying component 106, which facilitates the application of force to the nut 105. In this embodiment, the force-applying component 106 is two arc-shaped plates provided on the nut 105. That is, the nut 105 can be rotated on the lead screw 104 by twisting the arc-shaped plates. The force-applying component 106 can also be other structures that facilitate the rotation of the nut 105.
[0037] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0038] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
