Description

Technical Field

[0001] This invention belongs to the field of engineering component technology, specifically relating to quick-connect devices, and more particularly to a quick-installation pipeline connection system and its working method. Background Technology

[0002] During the use of existing engineering equipment, it is necessary to clean its interior. This requires the installation of an internal cleaning component to achieve the cleaning purpose. At the same time, without disassembling the housing, compressed air from the outside can be directly blown onto the internal cleaning component through an air pipe connector for maintenance without disassembly.

[0003] However, cleaning internal cleaning components requires high-pressure gas to meet the cleaning needs. When existing air pipe connectors connect external air pipes and air inlets, air leakage occurs when high-pressure gas is injected because the air pipe cannot fit tightly with the air inlet. At the same time, the vibration effect of high-pressure gas can also cause the air pipe connectors to loosen.

[0004] Therefore, there is an urgent need to develop a new quick-installation pipeline connection system and its working method to solve the technical problem of air leakage at the pipe joints when cleaning internal cleaning components with high-pressure gas.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Summary of the Invention

[0008] In one optional embodiment, the air inlet is stepped, so that the outer ring and the inner ring are threadedly connected to the outer stepped portion and the inner stepped portion of the air inlet, respectively.

[0009] In one optional embodiment, the connecting device includes: an outer ring, an inner ring, an inner movable component, and a locking component; the inner movable component is located in the inner ring and is movably guided to the inner ring, and the locking component is movably connected to both the inner ring and the inner movable component; when an outer tube of different diameter is inserted into the inner movable component, the inner movable component moves towards the air inlet in the inner ring, and the diameter of the inner movable component gradually decreases during the movement to clamp the outer tube and drive the outer tube to move towards the air inlet; when the locking component locks the inner movable component to the inner ring, the locking component abuts against the outer ring.

[0010] In one optional embodiment, the inner movable component includes: two movable semi-rings and two guide units; the inner diameter of the inner ring is gradually increased, and the inner diameter gradually increases from the side of the inner ring closer to the air inlet to the other side; the two movable semi-rings are located in the inner ring and are arranged in a ring shape; the two movable semi-rings are respectively connected to the inner ring through corresponding guide units; when the two movable semi-rings are inserted into outer tubes of different diameters, the two movable semi-rings move towards the air inlet in the inner ring through the corresponding guide units, and the diameter of the ring formed by the two movable semi-rings gradually decreases during the movement, so as to clamp the outer tube and drive the outer tube to move towards the air inlet.

[0011] In one optional embodiment, the guiding unit includes: a moving block and a guide post; two moving holes are provided on the inner sleeve ring, and two guide grooves are provided on the inner sleeve ring, with the guide grooves communicating with the corresponding moving holes; the moving block passes through the corresponding moving hole and is connected to the movable half-ring, and the guide post is elastically connected to the corresponding moving block and extends into the guide groove; the moving block drives the movable half-ring to move along the guide groove in the inner sleeve ring via the guide post, and the diameter of the ring formed by the two movable half-rings is consistent with the inner diameter of the inner sleeve ring, that is, when the two movable half-rings move towards the air inlet in the inner sleeve ring, the diameter of the ring formed by the two movable half-rings gradually decreases during the movement.

[0012] In one optional embodiment, the locking assembly includes: a plurality of locking blocks; a locking groove is formed on the movable block, and the guide post extends into the locking groove; a snap-fit ​​recess is provided in the guide groove; the locking blocks are movably connected to the corresponding locking grooves respectively; when the movable half-ring moves towards the air inlet in the inner sleeve until the movable block abuts against the movable hole, the locking block moves towards the guide post in the locking groove to push the guide post into the snap-fit ​​recess, thereby locking the movable half-ring and the inner sleeve.

[0013] In one optional embodiment, the guide post is provided with a guide ramp, and the guide ramp is positioned toward the locking block, that is, the locking block pushes the guide post to move through the guide ramp.

[0014] In one optional embodiment, the outer tube is provided with an outward folding portion, and the inner sleeve is provided with a guide folding portion; when the outward folding portion abuts against the guide folding portion and continues to move, the outward folding portion folds outward along the guide folding portion until it abuts against the air inlet, that is, the edge of the outer tube folds outward and abuts against the air inlet.

[0015] In one optional embodiment, the outward-folding portion and the guide folding portion are both arranged in a frustum shape and in opposite directions.

[0016] Secondly, this disclosure also provides a method of operating the quick-connect pipe connection system as described above, comprising: when an outer pipe of different diameter is inserted into the inner movable component of the connection device, the inner movable component drives the outer pipe to move toward the air inlet until the edge of the outer pipe folds outward and abuts against the air inlet and the locking component of the connection device locks the inner movable component and the inner sleeve ring, and prevents high-pressure gas from separating the outer pipe from the air inlet at the air inlet; and when the locking component locks the inner movable component and the inner sleeve ring, the locking component abuts against the outer sleeve ring to prevent the outer sleeve ring from moving relative to the air inlet.

[0017] The beneficial effects of this invention are that the inner movable component can adapt to outer tubes of different diameters, while clamping the outer tube and moving it toward the air inlet, so that the outer tube is turned outward and fits tightly with the air inlet. Even if high-pressure gas overflows at the air inlet, it can push the outer tube to fit more closely with the air inlet. Furthermore, after the locking component locks the inner movable component and the inner collar, the locking component can abut against the outer collar, ensuring that the entire connection device will not loosen, further improving the stability of the connection between the inner and outer pipes.

[0040] Research has revealed that diesel engines require an air filter assembly during operation. To adapt diesel engines to different operating environments, the air filter assembly can be maintained without disassembly by directly blowing compressed air from the outside through an air pipe connector onto the internal cleaning components without removing the air filter housing. However, cleaning the internal cleaning components requires high-pressure gas. Existing air pipe connectors, when connecting the external air pipe to the air inlet, cannot achieve a tight seal with the air inlet, leading to air leakage during high-pressure gas injection. Furthermore, the vibration effect of high-pressure gas can cause the air pipe connector to loosen.

[0041] Based on the above research, the present disclosure provides a quick-installation pipeline connection system, a diesel engine and its working method, which can adapt to outer pipes of different diameters. At the same time, it clamps the outer pipe and moves it toward the air inlet, so that the outer pipe is turned outward and fits tightly with the air inlet, ensuring that the connection device as a whole will not loosen, and further improving the stability of the connection between the inner pipeline and the outer pipe.

[0042] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0043] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0044] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0045] like Figures 1 to 7As shown, at least one embodiment provides a quick-connect pipe connection system, comprising: a housing 1, an inner cleaning component 2, an inner pipe 3, a connecting device 4, and an outer pipe 5; wherein the inner cleaning component 2 is located inside the housing 1, and each air inlet 31 of the inner pipe 3 is arranged facing the inner cleaning component 2; the outer ring 41 and the inner ring 42 of the connecting device 4 are respectively threadedly connected to the air inlet 32 ​​of the inner pipe 3, and the outer ring 41 is located outside the inner ring 42 and is threadedly connected to the inner ring 42; when the inner movable component 43 of the connecting device 4 is inserted... When different diameter outer tubes 5 are inserted, the inner movable component 43 drives the outer tube 5 to move towards the air inlet 32 ​​until the edge of the outer tube 5 folds outward and abuts against the air inlet 32, and the locking component 44 of the connecting device 4 locks the inner movable component 43 and the inner sleeve 42, preventing the high-pressure gas from separating the outer tube 5 from the air inlet 32 ​​at the air inlet 32; and when the locking component 44 locks the inner movable component 43 and the inner sleeve 42, the locking component 44 abuts against the outer sleeve 41 to prevent the outer sleeve 41 from moving relative to the air inlet 32.

[0046] Specifically, the outer pipe 5 is connected to a high-pressure air pump, and the high-pressure gas is input into the inner pipe 3 through the outer pipe 5 to clean the inner cleaning component 2.

[0047] Specifically, the internal cleaning component 2 can be an air filter element, used in the diesel engine air filter assembly.

[0048] In at least one embodiment, the inner movable component 43 can adapt to outer tubes 5 of different diameters and clamp the outer tube 5 to move towards the air inlet 32, so that the outer tube 5 is turned outward and closely fits the air inlet 32. Even if the high-pressure gas overflows at the air inlet 32, it can push the outer tube 5 to fit more closely with the air inlet 32. After the locking component 44 locks the inner movable component 43 and the inner collar 42, the locking component 44 can abut against the outer collar 41 to ensure that the connection device 4 as a whole will not loosen, further improving the stability of the connection between the inner pipe 3 and the outer pipe 5.

[0049] In at least one embodiment, please refer to Figure 4 The air inlet 32 ​​is stepped, so that the outer ring 41 and the inner ring 42 are threadedly connected to the outer stepped portion and the inner stepped portion of the air inlet 32, respectively.

[0050] Specifically, the air inlet 32 ​​is designed in a stepped shape, and the outer ring 41 and the inner ring 42 are threaded to the air inlet 32 ​​through the outer stepped part and the inner stepped part, respectively. At the same time, the outer ring 41 and the inner ring 42 are also threaded to each other, which facilitates the disassembly of the air pipe and improves the firmness and stability of the connection between the air pipe and the inlet air.

[0051] In at least one embodiment, please refer to Figure 5The connecting device 4 includes an outer ring 41, an inner ring 42, an inner movable component 43, and a locking component 44. The inner movable component 43 is located in the inner ring 42 and is movably guided to the inner ring 42. The locking component 44 is movably connected to both the inner ring 42 and the inner movable component 43. When an outer tube 5 of different diameter is inserted into the inner movable component 43, the inner movable component 43 moves towards the air inlet 32 ​​within the inner ring 42, and the diameter of the inner movable component 43 gradually decreases during the movement to clamp the outer tube 5 and drive the outer tube 5 to move towards the air inlet 32. When the locking component 44 locks the inner movable component 43 to the inner ring 42, the locking component 44 abuts against the outer ring 41.

[0052] Specifically, the outer ring 41 serves to connect the air inlet 32 ​​and facilitates the assembly of the inner ring 42 onto the outer ring 41.

[0053] Specifically, the inner collar 42 serves to install the inner moving component 43 and the locking component 44.

[0054] Specifically, the inner movable component 43 moves towards the air inlet 32 ​​within the inner sleeve 42, which can clamp the outer tube 5 and move it towards the air inlet 32 ​​together until the edge of the outer tube 5 folds outward and abuts against the air inlet 32, which also improves the sealing between the outer tube 5 and the air inlet 32.

[0055] Specifically, as the inner movable component 43 moves toward the air inlet 32, its diameter gradually decreases until it matches the outer tube 5, thus clamping the outer tube 5 and moving it toward the air inlet 32 ​​together. Meanwhile, since the outer tube 5 is made of flexible material, the inner movable component 43 and the inner sleeve 42 fit more tightly, resulting in a better sealing effect.

[0056] Specifically, the locking component 44 can move within the inner movable component 43, thereby locking the inner movable component 43 and the inner collar 42, thus playing a limiting role. At the same time, the locking component 44 abuts against the outer collar 41, which can prevent the outer collar 41 from shifting under the vibration of high-pressure gas.

[0057] In at least one embodiment, please refer to Figure 6The inner movable component 43 includes two movable semi-rings 431 and two guide units 432. The inner diameter of the inner ring 42 is gradually increased, and the inner diameter gradually increases from the side of the inner ring 42 closest to the air inlet 32 ​​to the other side. The two movable semi-rings 431 are located in the inner ring 42 and are arranged in a ring shape. The two movable semi-rings 431 are respectively connected to the inner ring 42 through corresponding guide units 432. When the two movable semi-rings 431 are inserted into outer tubes 5 of different diameters, the two movable semi-rings 431 move towards the air inlet 32 ​​in the inner ring 42 through the corresponding guide units 432. The diameter of the ring formed by the two movable semi-rings 431 gradually decreases during the movement, so as to clamp the outer tube 5 and drive the outer tube 5 to move towards the air inlet 32.

[0058] Specifically, the function of the two movable half-rings 431 is to expand or contract. When the two movable half-rings 431 expand in the inner ring 42, they can loosen the outer tube 5. When the two movable half-rings 431 contract in the inner ring 42, they can clamp the outer tube 5.

[0059] Specifically, the two movable semi-rings 431 are matched with the inner ring 42 with a gradually changing inner diameter, which can achieve the clamping of the outer tube 5.

[0060] In at least one embodiment, please refer to Figure 6 The guiding unit 432 includes a moving block 4321 and a guide post 4322. Two moving holes 421 are provided on the inner ring 42, and two guide grooves 422 are provided on the inner ring 42, with the guide grooves 422 communicating with the corresponding moving holes 421. The moving block 4321 passes through the corresponding moving hole 421 and connects to the movable half-ring 431. The guide post 4322 is elastically connected to the corresponding moving block 4321 and extends into the guide groove 422. The moving block 4321 drives the movable half-ring 431 to move along the guide groove 422 within the inner ring 42 via the guide post 4322. The diameter of the ring formed by the two movable half-rings 431 is consistent with the inner diameter of the inner ring 42. That is, when the two movable half-rings 431 move towards the air inlet 32 ​​within the inner ring 42, the diameter of the ring formed by the two movable half-rings 431 gradually decreases during the movement.

[0061] Specifically, since the movable block 4321 is guided and engaged with the guide groove 422 through the guide post 4322, and the movable block 4321 is connected to the movable half ring 431, the movable block 4321 can be moved along the F1 direction.

[0062] Specifically, since the inner diameter of the inner ring 42 is gradually changed, and a guide groove 422 is provided on the inner ring 42, when the guide post 4322 moves along the guide groove 422, it is equivalent to the two movable half rings 431 being able to expand or contract. When the two movable half rings 431 expand, they can loosen the outer tube 5, and the outer tube 5 can be pulled out from between the two movable half rings 431. When the two movable half rings 431 contract, they clamp the outer tube 5. At the same time, the two movable half rings 431 move in the F1 direction, which can drive the outer tube 5 to move in the F1 direction, that is, drive the outer tube 5 to move towards the air inlet 32 ​​in the inner ring 42.

[0063] In at least one embodiment, please refer to Figure 7 The locking assembly 44 includes: a plurality of locking blocks 441; a locking groove 4321a is provided on the movable block 4321, and the guide post 4322 extends into the locking groove 4321a; a snap-fit ​​recess 423 is provided in the guide groove 422; the locking blocks 441 are movably connected to the corresponding locking grooves 4321a; when the movable half ring 431 moves towards the air inlet 32 ​​in the inner sleeve 42 until the movable block 4321 abuts against the movable hole 421, the locking block 441 moves towards the guide post 4322 in the locking groove 4321a to push the guide post 4322 into the snap-fit ​​recess 423, that is, to lock the movable half ring 431 and the inner sleeve 42.

[0064] Specifically, the locking block 441 is used to push the guide post 4322 to move. After the guide post 4322 is pushed into the locking recess 423, the moving block 4321 can no longer move in the moving hole 421, that is, the movable half ring 431 and the inner ring 42 are locked.

[0065] In at least one embodiment, please refer to Figure 7 The guide post 4322 is provided with a guide slope 4322a, and the guide slope 4322a is positioned toward the locking block 441, that is, the locking block 441 pushes the guide post 4322 to move through the guide slope 4322a.

[0066] Specifically, the guide post 4322 is elastically connected to the moving block 4321 through an elastic element. When the guide post 4322 moves to the locking recess 423, pressing the locking block 441 can squeeze the guide post 4322 into the locking recess 423 through the guide slope 4322a, thereby forming a limiting relationship. The moving block 4321 can no longer move, that is, it locks the movable half ring 431 and the inner ring 42.

[0067] In at least one embodiment, please refer to Figure 4The outer tube 5 is provided with an outwardly folded portion 51, and the inner sleeve 42 is provided with a guide folding portion 424; the outwardly folded portion 51 and the guide folding portion 424 are both arranged in a frustum shape and are in opposite directions; when the outwardly folded portion 51 abuts against the guide folding portion 424 and continues to move, the outwardly folded portion 51 folds outward along the guide folding portion 424 until it abuts against the air inlet 32, that is, the edge of the outer tube 5 folds outward and abuts against the air inlet 32.

[0068] Specifically, when the outward-folding part 51 folds outward on the guide folding part 424, it can ensure that the edge of the outer tube 5 is close to the air inlet 32. At the same time, the outward-folding shape can guide the overflowing high-pressure gas to exert force on the outward-folding part 51, so that the outward-folding part 51 and the guide folding part 424 are closer together, that is, improve the sealing between the two.

[0069] Based on the same technical concept, at least one embodiment also provides a method of operation using the quick-connect pipe connection system as described above, which includes: when an outer pipe 5 of different diameter is inserted into the inner movable component 43 of the connecting device 4, the inner movable component 43 drives the outer pipe 5 to move toward the air inlet 32 ​​until the edge of the outer pipe 5 is turned outward and abuts against the air inlet 32, and the locking component 44 of the connecting device 4 locks the inner movable component 43 and the inner sleeve 42, and prevents high-pressure gas from separating the outer pipe 5 from the air inlet 32 ​​at the air inlet 32; and when the locking component 44 locks the inner movable component 43 and the inner sleeve 42, the locking component 44 abuts against the outer sleeve 41 to prevent the outer sleeve 41 from moving relative to the air inlet 32.

[0070] In summary, the present invention can adapt to outer tubes of different diameters through the inner movable component, while clamping the outer tube and moving it towards the air inlet, so that the outer tube is turned outward and closely fits the air inlet. Even if high-pressure gas overflows at the air inlet, it can push the outer tube to fit the air inlet even more closely. Furthermore, after the locking component locks the inner movable component and the inner collar, the locking component can abut against the outer collar, ensuring that the entire connection device will not loosen, further improving the stability of the connection between the inner and outer tubes.

[0071] In the description of the embodiments of the present invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" 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 the present invention based on the specific circumstances.

[0072] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as a second element, component, region, layer, or segment.

[0073] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.
