Description
Technical Field
[0001] The utility model relates to the technical field of fuel pipelines, in particular to a fuel pipeline with a quick connector. Background Art
[0002] A fuel pipeline is a pipeline used to transport fuel oil and is widely used in industry. Existing fuel pipelines are all segmented structures, and the fuel pipelines are connected in sequence through joints to increase the length, so that a certain number of segmented fuel pipelines can be connected through joints to form a fuel pipeline of a specified length as needed.
[0003] There are various types of joints used for splicing fuel pipelines in the prior art. Chinese invention patent publication number CN117989395 discloses a high-pressure pipeline connection device and a method of use. The high-pressure pipeline connection device includes a pipe joint and two symmetrically arranged fastening sleeves. The pipe joint is used to connect the connected pipe, and the two fastening sleeves are used to provide a radial fastening force for the pipe joint. Specifically, the connected pipe is inserted into the pipe joint, and conical fastening sections are symmetrically arranged at both ends of the pipe joint. The conical fastening sections are provided with threads. After the connected pipe is inserted into the pipe joint, the fastening sleeve is threadedly assembled on the conical fastening section. When the fastening sleeve moves along the length direction of the pipe joint toward the middle direction of the pipe joint, the fastening sleeve can provide a radial force to the conical fastening section so that the conical fastening section is tightly pressed against the surface of the connected pipe, thereby making the connected pipe and the pipe joint tightly assembled to achieve the connection of the pipes. Although the pipe joint can be firmly assembled with the connected pipe, it still has the following defects in actual use: when the connected pipe is deformed, the connected pipe is inserted into the pipe joint and separated from the inner wall of the pipe joint. Even if the tightening sleeve thread exerts radial force on the pipe joint, the connected pipe cannot be fixed. In order to ensure the connection effect of the pipe, we provide a fuel pipe with a quick connector. Utility Model Content

[0029] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1
[0030] like Figure 1 As shown, it is a schematic diagram of the structure of the fuel pipeline with a quick connector in this embodiment. The fuel pipeline in this embodiment is formed by sequentially connecting the segmented fuel pipeline and the connector body, and multiple segmented fuel pipelines are connected through the connector body to form the required length; Figure 2 as well as Figure 3 As shown, the connector body in this embodiment includes a sub-connector 100 and a female connector 200. The sub-connector 100 and the female connector 200 are connected to form the connector body. In this embodiment, a fuel pipeline is installed on the sub-connector 100, and a fuel pipeline is also installed on the female connector 200. The fuel pipelines can be connected by connecting the sub-connector 100 and the female connector 200.
[0031] In this embodiment, in order to facilitate the docking of the sub-connector 100 and the female connector 200, the sub-connector 100 is fixedly connected to a connecting port 101 at one end relative to the female connector 200, and threads are distributed on the connecting port 101. In addition, a connecting sleeve 201 is rotatably provided at one end of the female connector 200 relative to the sub-connector 100. The connecting sleeve 201 is rotatably provided at the end of the female connector 200, and threads are also distributed on the inner wall of the connecting sleeve 201. The connecting sleeve 201 cooperates with the threads on the connecting port 101 so that the connecting sleeve 201 can be threadedly assembled on the connecting port 101, thereby making the sub-connector 100 and the female connector 200 docked and fixed.
[0032] When the connector body in this embodiment is in use, the fuel pipeline is assembled on the end of the sub-connector 100 away from the connection port 101 and the end of the female connector 200 away from the connection sleeve 201. After the fuel pipeline is connected to the sub-connector 100 and the female connector 200 respectively, the sub-connector 100 and the female connector 200 are docked, and the connection sleeve 201 is threadedly sleeved on the connection port 101. Then, the sub-connector 100 and the female connector 200 are connected, and the fuel pipeline can be connected and assembled in sequence to form a required length.
[0033] like Figure 4 as well as Figure 5 As shown, in this embodiment, a locking assembly 300 is provided at one end of the sub-joint 100 and the female joint 200 connected to the fuel pipeline, and the locking assembly 300 is used to lock the fuel pipeline at the end of the sub-joint 100 and the female joint 200. In this embodiment, the locking assembly 300 includes a threaded interface 301, and the threaded interface 301 is fixedly connected to the sub-joint 100 and the female joint 200. A threaded sleeve 302 is provided on the threaded interface 301. The threaded sleeve 302 is threadedly assembled with the threaded interface 301 and can be moved along the length direction of the threaded interface 301 by rotation. In this embodiment, a plurality of locking grooves 301a are longitudinally distributed on the threaded interface 301. When the threaded sleeve 302 moves along the threaded interface 30 When the threaded interface 301 moves in the length direction, the locking groove 301a can be driven to contract so that the threaded interface 301 is locked. In this embodiment, an inner support tube 303 is coaxially arranged in the threaded interface 301, and the inner support tube 303 is coaxially arranged with the threaded interface 301, and an annular cavity is formed between the inner support tube 303 and the threaded interface 301. In this embodiment, when the sub-connector 100 and the female connector 200 are assembled with the fuel pipeline, the end of the fuel pipeline is inserted into the annular cavity between the threaded interface 301 and the inner support tube 303. When the threaded sleeve 302 rotates and moves along the length direction of the threaded interface 301, the locking groove 301a is contracted, and the threaded interface 301 and the inner support tube 303 cooperate to tightly lock the fuel pipeline in the annular cavity.
[0034] It is worth noting that after the fuel pipeline is assembled in the annular cavity, the inner support tube 303 abuts against the inner wall of the fuel pipeline. Therefore, when the fuel pipeline is deformed, the inner support of the inner support tube 303 restores the deformation of the fuel pipeline until it is inserted into the annular cavity. The threaded interface 301 locks the fuel pipeline by moving the threaded sleeve 302, so that the fuel pipeline is fixed to the ends of the sub-connector 100 and the female connector 200, and then the fuel pipeline is connected to a specified length by docking and fixing the sub-connector 100 and the female connector 200. Example 2
[0035] like Figures 6-8 As shown, it is a structural schematic diagram of the mating component 400 in this embodiment. The difference between this embodiment and embodiment 1 is that the sub-connector 100 and the female connector 200 in this embodiment are internally assembled with the mating component 400, and the mating component 400 is used for the rapid assembly of the sub-connector 100 and the female connector 200, so that the rapid assembly of the sub-connector 100 and the female connector 200 can realize the connection of the fuel pipeline.
[0036] like Figure 7 as well as Figure 8 As shown, the mating component 400 in this embodiment includes a transition chamber 401 arranged inside the sub-connector 100 and the female connector 200, and a plurality of through holes are distributed on the transition chamber 401. When the fuel enters the sub-connector 100 and the female connector 200 through the fuel pipeline, it can pass through the transition chamber 401 through the through holes. In this embodiment, the transition chamber 401 is a conical structure, and the cone top of the transition chamber 401 is fixedly connected with a fixing cylinder 402, and the fixing cylinder 402 is a hollow structure. In this embodiment, a docking column 402a is connected to the fixing cylinder 402 located in the sub-connector 100, and a plug-in hole 402c is provided at the end of the fixing cylinder 402 located in the female connector 200. When the sub-connector 100 and the female connector 200 are docked and assembled, the docking column 402a is inserted into the fixing cylinder 402 in the female connector 200 through the plug-in hole 402c, so as to achieve the purpose of rapid positioning and assembly, and then the sub-connector 100 and the female connector 200 are docked and fixed by threading the connecting sleeve 201 on the connecting port 101.
[0037] Since the sub-connector 100 and the female connector 200 are docked and fixed by threaded assembly between the connecting sleeve 201 and the connecting port 101, the connecting sleeve 201 and the connecting port 101 are prone to loosening after long-term use, causing the sub-connector 100 and the female connector 200 on the fuel pipeline to fall off. In order to solve this problem, in this embodiment, a telescopic spring 403 is provided in the fixing cylinder 402 located in the sub-connector 100 and the female connector 200, and one end of the docking column 402a in the sub-connector 100 extends into the fixing cylinder 402 and is sealed and slidably connected with the fixing cylinder 402, the end of the docking column 402a abuts on the telescopic spring 403, and the other end of the docking column 402a extends to the outside of the fixing cylinder 402. In this embodiment, a telescopic spring 403 is provided in the fixing cylinder 402 located in the female connector 200, and one end of the telescopic spring 403 is connected to the fixing cylinder 40 2, and the other end is connected with a buffer plate 402b, which is slidably and sealedly connected to the inner wall of the fixed tube 402. In this embodiment, when the sub-connector 100 and the female connector 200 are docked and fixed, the docking column 402a is inserted into the fixed tube 402 in the female connector 200 and presses on the buffer plate 402b to compress the telescopic spring 403 in the fixed tube 402. When the sub-connector 100 and the female connector 200 are assembled, the connecting sleeve 201 is threadedly connected to the connecting port 101, and the telescopic spring 403 generates elastic force due to compression to press on the sub-connector 100 and the female connector 200, so that the connecting sleeve 201 is firmly fixed to the connecting port 101 and the loosening of the connecting sleeve 201 is avoided, thereby ensuring the stable effect after the sub-connector 100 and the female connector 200 are connected, and avoiding the problem of loosening between the sub-connector 100 and the female connector 200.
[0038] The working principle of the utility model is as follows: the fuel pipeline is respectively connected to the ends away from the sub-joint 100 and the female joint 200. Specifically, the fuel pipeline enters the annular cavity of the inner support tube 303 and the threaded interface 301 by plugging, and the threaded interface 301 is contracted by rotating the threaded sleeve 302, so that the fuel pipeline is assembled on the sub-joint 100 and the female joint 200, and then the sub-joint 100 and the female joint 200 are docked, and the docking column 402a in the sub-joint 100 is inserted into the fixing cylinder 402 in the female joint 200, and then the connecting sleeve 201 on the female joint 200 is threadedly connected to the connecting port 101 of the sub-joint 100, and the telescopic spring 403 in the fixing cylinder 402 generates a resisting force on the sub-joint 100 and the female joint 200, so that the connecting sleeve 201 is fastened to the connecting port 101, thereby ensuring the docking and stable effect of the sub-joint 100 and the female joint 200, and the fuel pipelines are connected in sequence through the sub-joint 100 and the female joint 200 to form the required length to meet the use requirements.
[0039] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
