Description

Technical Field

[0001] This solution belongs to the field of oil pipe fittings, specifically involving a vibration-resistant and anti-detachment oil delivery fitting. Background Technology

[0002] Oil pipelines are the main facilities used for unloading and transferring oil. Generally, an oil pipeline is composed of multiple single pipes of the same specifications connected together. Because oil needs to withstand large transmission pressure during transportation, the connection between adjacent single pipes has high requirements.

[0003] A search revealed a utility model patent with authorization announcement number CN216618859U, which discloses an oil pipeline sealing joint. The oil pipeline sealing joint includes: a joint pipe and connectors symmetrically installed at both ends of the joint pipe. A through inner hole is provided between the joint pipe and the two connectors. Flanges are provided at both ends of the joint pipe. Positioning grooves matching the flanges are provided at the connection positions of the connectors and the joint pipe.

[0004] Traditional oil transfer joints mostly use rigid flange connections or threaded fasteners, which are prone to loosening, leakage, or even breakage under vibration conditions. Although some flexible joints can buffer vibration, they lack reliable anti-detachment structures, and long-term use still poses safety hazards. Utility Model Content

[0005] The purpose of this solution is to provide a vibration-resistant and anti-detachment oil delivery joint to address the problems of traditional oil delivery joints, which mostly use rigid flange connections or threaded fasteners and are prone to loosening, leakage, or even breakage under vibration conditions. While some flexible joints can buffer vibration, they lack a reliable anti-detachment structure, and long-term use still poses safety hazards.

[0006] To achieve the above objectives, this solution provides a vibration-resistant and anti-detachment oil delivery connector, comprising two connectors, which are movably connected by a connecting ball shaft. An oil pipe flange is bolted to each connector. A clamp first and a clamp second are fitted together on the outer sides of the connector and the oil pipe flange. The clamp first and the clamp second are hinged together, and a locking mechanism is provided between the clamp first and the clamp second.

[0007] The principle of this solution is as follows: During use, the oil pipe flange is installed at the joint with bolts. Then, clamps one and two are placed on the sides of both. The connecting plate is controlled by a pull ring, causing the retaining beads on the connecting plate to engage with the retaining block. This locks clamps one and two, ensuring stable anti-detachment protection between the joint and the oil pipe flange. Then, the other oil pipe flange is connected using the same method. In this way, the two oil pipe flanges can be connected by two joints. Since multiple connecting ball joints are provided between the two joints, there is a certain amount of room for movement between the joints, making them less prone to breakage due to vibration.

[0008] The technical advantages of this solution are as follows: by setting two original joints and sealing them together with a common sealing sleeve, and then setting multiple connecting ball shafts distributed in a ring array between the two joints, a flexible and movable connection is formed between the joints. This not only allows for multi-directional adjustment within a certain range, but also effectively absorbs vibration energy, reduces stress concentration caused by mechanical vibration, and significantly reduces the risk of metal fatigue fracture.

[0009] By installing two hinged clamps, one and two, between the oil pipe flange and the joint, and then installing a locking mechanism between the two clamps, the oil pipe flange and the joint can be stably locked together to prevent them from coming apart.

[0010] Furthermore, multiple connecting ball shafts are provided, and these multiple connecting ball shafts are distributed in a circular array along the circumference of the joint. The arrangement of multiple connecting ball shafts allows for a certain amount of movement between the joints, making them less prone to breakage due to vibration.

[0011] Furthermore, a retaining ring is fixedly connected to the outer side of each connector, and a sealing sleeve is fixedly connected to each of the retaining rings. The retaining rings and sealing sleeve provide a sealing and protective function between the two connectors.

[0012] Furthermore, the locking mechanism includes a fixing block fixedly connected to clamp one, a locking block fixedly connected to the fixing block, a hollow block fixedly connected to clamp two, a limit block slidably connected inside the hollow block, a sliding rod fixedly connected to the limit block, the sliding rod passing through the hollow block and slidably connected to the hollow block, a connecting plate fixedly connected to the end of the sliding rod, and a locking bead fixedly connected to the connecting plate, the locking bead engaging with the locking block. Through the locking mechanism, clamp one and clamp two can be locked, thereby ensuring stable anti-detachment protection between the clamp one and clamp two joints and the oil pipe flange.

[0013] Furthermore, the limiting block is equipped with ball bearings, which are slidably connected to the inner surface of the hollow block. The ball bearings reduce the friction between the limiting block and the hollow block.

[0014] Furthermore, a spring is installed inside the hollow block. One end of the spring is fixedly connected to the limiting block, and the other end of the spring is fixedly connected to the inner surface of the hollow block. Through the spring, the reaction force can be applied to the retaining bead via the limiting block, sliding rod, and connecting plate.

[0015] Furthermore, a pull ring, made of stainless steel, is fixedly connected to the connecting plate. The pull ring facilitates the lateral pulling of the connecting plate. Attached Figure Description

[0023] The basic implementation examples are as follows: Figures 1-5As shown: A vibration-resistant and anti-detachment oil delivery connector includes two connectors 1, which are movably connected by a connecting ball shaft 2. Multiple connecting ball shafts 2 are arranged in a circular array along the circumference of the connectors 1. The arrangement of multiple connecting ball shafts 2 allows for sufficient movement between the connectors 1, preventing breakage due to vibration. A fixing ring 3 is fixedly connected to the outer side of each connector 1, and a sealing sleeve 4 is fixedly connected to all fixing rings 3. The fixing rings 3 and the sealing sleeve 4 provide a sealing and protective function between the two connectors 1.

[0024] like Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, a pipe flange 5 is bolted to the connector 1. A clamp 6 and a clamp 7 are fitted together on the outer sides of both the connector 1 and the pipe flange 5. The clamps 6 and 7 are hinged together, and a locking mechanism 8 is provided between them. The locking mechanism 8 locks the clamps 6 and 7, ensuring stable anti-detachment protection between the connector 1 and the pipe flange 5. The locking mechanism 8 includes... The system includes a fixing block 81 fixedly connected to clamp 6, a locking block 82 fixedly connected to fixing block 81, a hollow block 83 fixedly connected to clamp 7, a limiting block 84 slidably connected inside the hollow block 83, a sliding rod 85 fixedly connected to the limiting block 84, the sliding rod 85 passing through the hollow block 83 and slidably connected to the hollow block 83, a connecting plate 88 fixedly connected to the end of the sliding rod 85, a retaining bead 89 fixedly connected to the connecting plate 88, and the retaining bead 89 engaging with the locking block 82. A ball bearing 86 is provided on the limiting block 84, and the ball bearing 86 is slidably connected to the inner surface of the hollow block 83. The ball bearing 86 reduces the friction between the limiting block 84 and the hollow block 83. A spring 87 is provided inside the hollow block 83, one end of the spring 87 is fixedly connected to the limiting block 84, and the other end of the spring 87 is fixedly connected to the inner surface of the hollow block 83. The spring 87 allows the reaction force to act on the retaining bead 89 via the limiting block 84, slide rod 85, and connecting plate 88. A pull ring 810, made of stainless steel, is fixedly connected to the connecting plate 88. The pull ring 810 facilitates the lateral pulling of the connecting plate 88.

[0025] The specific implementation process of this utility model is as follows: In use, the oil pipe flange 5 is installed at the joint 1 with bolts, and then the clamp 6 and clamp 7 are put on the sides of the two. The connecting plate 88 is controlled by the pull ring 810, so that the locking ball 89 on the connecting plate 88 is locked into the locking block 82. This can lock the clamp 6 and clamp 7, thereby ensuring that the clamp 6 and clamp 7 provide stable anti-detachment protection between the joint 1 and the oil pipe flange 5. Then, the other oil pipe flange 5 is connected in the same way. In this way, the two oil pipe flanges 5 can be connected by two joints 1. Since multiple connecting ball shafts 2 are provided between the two joints 1, there is a certain amount of movement space between the joints 1, which is not easy to break due to vibration.

[0026] This solution involves setting two original joints 1, with a common sealing sleeve 4 between the two joints 1, and then setting multiple connecting ball shafts 2 arranged in a ring array between the two joints 1, so that the joints 1 form a flexible movable connection. This not only allows for multi-directional adjustment within a certain range, but also effectively absorbs vibration energy, reduces stress concentration caused by mechanical vibration, and significantly reduces the risk of metal fatigue fracture.

[0027] By installing two hinged clamps, 6 and 7, between the oil pipe flange 5 and the joint 1, and then installing a locking mechanism 8 between the two clamps, the oil pipe flange 5 and the joint 1 can be stably locked together to prevent them from separating.

[0028] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model.
