Description

Technical Field

[0001] This utility model relates to the field of oil pipeline technology, and in particular to an oil pipeline connector that can be quickly disassembled. Background Technology

[0002] Oil pipelines are specialized pipeline systems used for long-distance transportation of oil and related products. They are one of the core infrastructures of modern energy transportation. They achieve efficient, safe, and continuous transportation through closed pipelines, and have advantages such as large transport capacity, low cost, and strong environmental protection. They are crucial to global energy supply and economic development. Pipelines are made of high-strength steel pipes, buried underground or erected in the air, and their diameter is usually 20 to 120 centimeters. Pump stations are powered by centrifugal pumps or compressors to overcome frictional resistance and drive fluid flow.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: Existing oil pipelines generally adopt traditional technologies such as flange bolt connection, welding or thread locking. Their structural design focuses on high pressure sealing and long-term stability, but ignores the need for convenience in installation and maintenance. Flange connection requires multiple sets of high-strength bolts to be tightened one by one. When disassembling, not only is it necessary to reverse the operation and repeatedly calibrate the torque, but it is also easy for the bolts to get stuck due to rust or deformation. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology is not convenient for quickly disassembling oil pipelines. Therefore, we propose an oil pipeline connector that can be quickly disassembled.

[0005] To achieve the above objectives, this application adopts the following technical solution: a quick-disassembly oil pipeline connector, comprising a first oil pipeline, a second oil pipeline disposed on the right side of the first oil pipeline, a first interface disposed between the first and second oil pipelines, a second interface disposed at the bottom of the first interface, a first positioning block fixedly connected to the bottom outer side of the first interface, a second positioning block fixedly connected to the top outer side of the second interface, a housing fixedly connected to the top of the second interface, a disc disposed inside the housing, a circular block fixedly connected to the back of the disc, a connecting block sleeved on the surface of the circular block, a limit block movably connected to the left side of the connecting block via a pin, and a motor fixedly connected to the outer side of the disc.

[0006] Preferably, a ventilation hole is provided on the right side of the box body, and a dustproof net is fixedly connected inside the ventilation hole.

[0007] Preferably, the bottom of the inner wall of the box is fixedly connected to a horizontal block, and a through hole is provided on the left side of the box.

[0008] Preferably, a sliding groove is provided on both sides of the inner wall of the through hole, and a slider is slidably connected inside the sliding groove. The inner side of the slider is fixedly connected to the surface of the limiting block.

[0009] Preferably, a fixing sleeve is fitted onto the surface of the motor, and the inner side of the fixing sleeve is fixedly connected to the outer side of the housing.

[0010] Preferably, the first positioning block and the second positioning block have positioning holes inside, and a protective block is fixedly connected to the top of the outer side of the first interface, the protective block being located on the top of the motor.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] In this utility model, the motor, disc, connecting block, pin, and limit block are connected to start the motor. The output end of the motor rotates, causing the disc to rotate. The disc rotates, causing the block to rotate. The block rotates, causing the connecting block to rotate. The connecting block rotates, causing the limit block to move. The limit block is moved into the positioning hole to position the first positioning block and the second positioning block, which is used to merge the first connection port and the second connection port for installation.

[0013] In this invention, the ventilation holes and dustproof nets allow for ventilation of the parts inside the box, preventing them from getting damp. The dustproof nets also prevent dust from entering the box. Attached Figure Description

[0020] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods without changing the essential spirit of this utility model. Therefore, the following specific embodiments and accompanying drawings are merely exemplary descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction on the technical solution of this utility model.

[0021] Reference Figures 1-4 As shown, this utility model provides a technical solution: a quick-disassembly oil pipeline connector, including a first oil pipeline 1, a second oil pipeline 2 disposed on the right side of the first oil pipeline 1, a first interface 3 disposed between the first oil pipeline 1 and the second oil pipeline 2, a second interface 4 disposed at the bottom of the first interface 3, a first positioning block 5 fixedly connected to the bottom outer side of the first interface 3, a second positioning block 6 fixedly connected to the top outer side of the second interface 4, a box body 7 fixedly connected to the top of the second interface 4, a disc 8 disposed inside the box body 7, a round block 9 fixedly connected to the back of the disc 8, and a connecting block 10 sleeved on the surface of the round block 9. The left side of the connecting block 10 is movably connected to the limiting block 11 via a pin. The outer side of the disc 8 is fixedly connected to the motor 12. Through the connection of the motor 12, disc 8, connecting block 10, pin, limiting block 11, etc., the motor 12 can be started. The output end of the motor 12 rotates, causing the disc 8 to rotate. The rotation of the disc 8 causes the circular block 9 to rotate. The rotation of the circular block 9 causes the connecting block 10 to rotate. The rotation of the connecting block 10 causes the limiting block 11 to move. The limiting block 11 is moved into the positioning hole 20 to position the first positioning block 5 and the second positioning block 6, which is used to merge and install the first connecting port and the second connecting port.

[0022] Reference Figure 3 As shown in this embodiment: a ventilation hole 13 is provided on the right side of the box body 7, and a dustproof net 14 is fixedly connected inside the ventilation hole 13. Through the setting of the ventilation hole 13 and the dustproof net 14, the parts inside the box body 7 can be ventilated to prevent the parts from getting damp. Through the setting of the dustproof net 14, dust can be prevented from entering the box body 7.

[0023] Reference Figure 4As shown in this embodiment: horizontal blocks 15 are fixedly connected to the bottom of the inner wall of the box body 7, and a through hole 16 is provided on the left side of the box body 7. The horizontal blocks 15 can limit the position of the disc 8 and prevent the disc 8 from shaking when rotating.

[0024] Reference Figure 3 As shown in this embodiment: both sides of the inner wall of the through hole 16 are provided with sliding grooves 17, and a slider 18 is slidably connected inside the sliding groove 17. The inner side of the slider 18 is fixedly connected to the surface of the limiting block 11. Through the setting of the sliding groove 17 and the slider 18, a dovetail-shaped slider 18 is correspondingly arranged at the bottom of the limiting block 11, and the two form a precise sliding fit. When the limiting block 11 is axially displaced by the driving mechanism, the slider 18 slides in a direction along the guide surface of the sliding groove 17. Its wedge-shaped contact surface effectively decomposes the radial component force, restricting the degree of freedom of the limiting block 11 to a single translational motion.

[0025] Reference Figure 4 As shown in this embodiment: a fixing sleeve 19 is fitted onto the surface of the motor 12, and the inner side of the fixing sleeve 19 is fixedly connected to the outer side of the housing 7. By setting the fixing sleeve 19, the motor 12 can be positioned to prevent the motor 12 from shaking during operation.

[0026] Reference Figure 2 As shown in this embodiment: the first positioning block 5 and the second positioning block 6 are provided with positioning holes 20 inside, and a protective block 21 is fixedly connected to the top of the outer side of the first interface 3. The protective block 21 is located on the top of the motor 12. Through the setting of the positioning holes 20, the first interface 3 and the second interface 4 can be merged in conjunction with the limiting block 11. Through the setting of the protective block 21, dust can be reduced from adhering to the surface of the motor 12.

[0027] Working principle: After the user starts the motor 12, its output end drives the disc 8 to rotate in a directional manner through the keyway or coupling; the circular block 9 embedded in the eccentric position of the disc 8 rotates synchronously, forming a compound motion trajectory; the outer circumference of the circular block 9 and the inner groove of the connecting block 10 form a sliding fit, converting the rotational torque into the reciprocating swing or linear motion of the connecting block 10; the end of the connecting block 10 is linked with the limiting block 11 through the pin, driving it to translate along the preset path; when the limiting block 11 moves to the axial alignment position of the positioning hole 20, it is embedded in the positioning hole 20 under the spring preload or the continuous drive of the motor 12, forming a rigid constraint; at this time, the limiting block 11 simultaneously engages the groove of the first positioning block 5 and the flange of the second positioning block 6, realizing the axial and circumferential double locking of the two positioning blocks, thereby ensuring that the flange sealing surfaces of the first connection port and the second connection port are completely fitted, completing the rapid docking and precise positioning of the pipeline.

[0028] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
