Description

Technical Field

[0001] This utility model relates to the field of engine pipeline interfaces, specifically an engine pipeline interface anti-detachment structure. Background Technology

[0002] The engine pipeline interface anti-detachment structure is a specially designed structure to ensure that the connection between the lubricating oil addition pipeline and the engine is secure and not easily detached. This structure effectively prevents pipeline loosening or detachment caused by factors such as vibration and impact through a specific locking mechanism or fastening device, thereby ensuring smooth lubricating oil addition and normal engine operation. It is usually located on the engine in a location that is convenient for lubricating oil addition. It not only enhances the reliability of pipeline connection, but also improves the overall safety and stability of the engine. This anti-detachment structure design fully considers the complexity and harshness of the engine's working environment and is an indispensable and important component in engine maintenance.

[0003] Chinese patent CN220770452U discloses a pipe interface connection structure, including a sleeve and a connecting pipe. The sleeve has an annular groove concentric with the sleeve, and a matching sealing ring is fitted in the annular groove. This utility model uses a sleeve to connect two mating connecting pipes. The groove on the side of the end of the connecting pipe is matched with the locking block in the sleeve to achieve axial constraint. The sealing ring seals the gap between the pipe and the sleeve to prevent leakage. This utility model has a simple structure, is easy to process and manufacture, and is convenient for connecting pipes.

[0004] The pipe interface connection structure of the above patent relies on the friction between the locking block and the fixed position to achieve the restriction after rotation and locking. However, long-term use will reduce the friction, resulting in a decrease in the locking and anti-loosening effect. Even if the locking block slides into the fixed position, it is easy to fall off. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-detachment structure for engine pipeline interfaces. After the connecting ring slides into the outside of the extension tube and rotates, the roller will contact the protruding strip inside the second mounting groove. The protruding strip will cause the roller to rotate, and the rotation of the roller will push the pressing piece, so that the pressing piece is tightly attached to the connecting ring, thereby restricting the connecting ring and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an engine pipeline interface anti-detachment structure, including an extension tube, a connecting ring provided on one side of the outer side of the extension tube, and a first mounting groove provided on both sides of the inner side of the connecting ring, the first mounting groove extending through and to both ends of the connecting ring, a second mounting groove extending around the center of the connecting ring on one side of the two first mounting grooves, a protruding strip being provided around the inside of the second mounting groove, and the protruding strip being welded and fixed to the connecting ring, a fixing block being provided inside the two first mounting grooves, and a roller being provided at one end of the fixing block.

[0007] Preferably, the fixing block is welded and fixed to the outer wall of the extension tube, and the roller is embedded inside the fixing block and rotatably connected to the inside of the fixing block.

[0008] Preferably, the roller has a through-hole, and a threaded rod is provided through the through-hole, with the outside of the threaded rod engaging with the internal thread of the mounting hole.

[0009] Preferably, sliding blocks are provided on both sides of the outer side of the threaded rod, and the sliding blocks are welded and fixed to the outer wall of the threaded rod. A sliding rail is provided on the outside of the sliding block, and the sliding rail is recessed inside the fixed block. The outside of the sliding block and the inside of the sliding rail are slidably connected.

[0010] Preferably, a pressing plate is provided at the end of the threaded rod facing the connecting ring, and the pressing plate is rotatably connected to the threaded rod.

[0011] Preferably, the two second mounting slots are mirror-distributed on both sides inside the connecting ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In this invention, after the connecting ring moves toward the extension tube and rotates to fix the connecting ring, the fixing block drives the roller and the pressing plate to slide together in the first mounting groove and move into the second mounting groove. The sliding of the roller in the second mounting groove causes the protruding strip to drive the roller to rotate. The rotation of the roller causes the mounting hole to form a threaded engagement with the outside of the threaded rod. The threaded engagement, combined with the sliding block sliding in the sliding rail, causes the roller to rotate and causes the pressing plate to press tightly against the connecting ring, thereby fixing the connecting ring. Fixing is achieved by sliding and rotation. The additional pressing plate for fixing is hidden between the extension tube and the connecting ring. The restriction is achieved by pressing and will not reduce the restriction and anti-fall-off ability due to long-term use. Attached Figure Description

[0021] The present invention will be further described below with reference to specific embodiments.

[0022] Example 1

[0023] like Figure 1 As shown, an engine pipeline interface anti-detachment structure of this embodiment includes an extension tube 1. The extension tube 1 is used to connect to the lubricant storage position inside the engine. The extension tube 1 also facilitates the filling and emptying of lubricant. A connecting ring 2 is provided on one side of the extension tube 1. After the anti-detachment structure wraps the extension tube 1, the connecting ring 2 can wrap the extension tube 1. The two sides inside the connecting ring 2 are provided with first mounting grooves 4, and the first mounting grooves 4 penetrate through and extend to both ends of the connecting ring 2. The reserved first mounting grooves 4 can facilitate the lateral sliding of the extension tube 1 and facilitate the insertion of the connecting ring 2.

[0024] Among them, such as Figure 2 As shown, a fixing block 7 is provided inside each of the two first mounting slots 4, and the fixing block 7 is welded and fixed to the outer wall of the extension tube 1. When the connecting ring 2 is slid laterally into the outside of the extension tube 1, the fixing block 7 can slide in the first mounting slot 4.

[0025] In addition, in order to facilitate locking of the connecting ring 2 and prevent the connecting ring 2 from falling off, a second mounting groove 5 is provided on one side of the two first mounting grooves 4 around the center of the connecting ring 2. The two second mounting grooves 5 are mirror-distributed on both sides inside the connecting ring 2, and the fixing block 7 slides laterally in the first mounting groove 4.

[0026] To ensure a tight fit with connecting ring 2 and prevent connecting ring 2 from falling off, such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a protruding strip 6 is arranged around the inside of the second mounting groove 5, and the protruding strip 6 is welded and fixed to the connecting ring 2. A roller 8 is provided at one end of the fixing block 7. When the connecting ring 2 slides laterally to the outside of the extension tube 1, the roller 8 will fit against the outside of the protruding strip 6.

[0027] The roller 8 is embedded inside the fixing block 7 and rotatably connected to the interior of the fixing block 7. When the connecting ring 2 rotates and the fixing block 7 moves within the second mounting groove 5, the protruding strip 6 causes the roller 8 to rotate. Figure 6 As shown, a mounting hole 11 is provided through the inside of the roller 8, and a threaded rod 10 is provided through the inside of the mounting hole 11. The outside of the threaded rod 10 is threaded with the inside of the mounting hole 11. When the roller 8 slides along the second mounting groove 5, the rotation of the roller 8 will produce a threaded engagement with the threaded rod 10.

[0028] In addition, in order to limit the rotation of the threaded rod 10, sliding blocks 13 are provided on both sides of the outer side of the threaded rod 10, and the sliding blocks 13 are welded and fixed to the outer wall of the threaded rod 10. A sliding rail 12 is provided on the outside of the sliding block 13, and the sliding rail 12 is recessed inside the fixed block 7. The outside of the sliding block 13 and the inside of the sliding rail 12 are slidably connected. After the mounting hole 11 is threadedly engaged with the threaded rod 10 and relative movement occurs with the threaded rod 10, the sliding rail 12 will restrict the sliding block 13, causing the rotational movement of the threaded rod 10 to change into a transverse linear movement. The transverse linear movement will push the threaded rod 10 to extend out of the roller 8.

[0029] The threaded rod 10 extends from the roller 8 and can contact and press the connecting ring 2. Pressing the connecting ring 2 can fix the connecting ring 2. In order to increase the friction coefficient between the connecting ring 2 and the threaded rod 10, and to increase the contact area between the threaded rod 10 and the connecting ring 2, a pressing piece 9 is provided at the end of the threaded rod 10 facing the connecting ring 2. The pressing piece 9 is rotatably connected to the threaded rod 10. When the roller 8 slides and rotates in the second mounting groove 5, the pressing piece 9 will continue to press against the connecting ring 2. The threaded engagement combined with the pressing piece 9 and the connecting ring 2 can press against and restrict the connecting ring 2.

[0030] like Figure 2 and Figure 6 As shown, the extension tube 1 is provided with a filling block 3 inside, and the filling block 3 is welded and fixed to the connecting ring 2. When the connecting ring 2 is inserted into the outside of the extension tube 1, the filling block 3 will fill the outside of the extension tube 1 together with the connecting ring 2. The outside of the filling block 3 is connected to the internal slot of the extension tube 1.

[0031] Working principle: When the anti-detachment structure is used to seal the outside of the extension tube 1, the connecting ring 2 is aligned with the fixing block 7 through the first mounting groove 4 inside. The connecting ring 2 moves toward the extension tube 1, and the fixing block 7 slides in the first mounting groove 4 until the roller 8 and the pressing plate 9 move to the position of the second mounting groove 5. Rotating the connecting ring 2 will cause the protruding strip 6 to rotate the roller 8. The rotation of the roller 8 will cause the mounting hole 11 to engage with the external thread of the threaded rod 10. The thread engagement causes the threaded rod 10 and the pressing plate 9 to move toward the connecting ring 2. As the connecting ring 2 continues to rotate, the pressing plate 9 presses tightly against the connecting ring 2, thus fixing the connecting ring 2.
