Description

Technical Field

[0001] This utility model belongs to the field of engine pipe fittings technology, specifically relating to a misalignment prevention boss for the sealing port of an automotive engine pipe fitting. Background Technology

[0002] As the automotive industry places increasingly higher demands on quality control, error-proofing technologies are constantly evolving. Error-proofing methods that prevent errors from occurring at the physical level through product design innovation have become an important development direction. Error-proofing methods that utilize geometric differences, such as bosses, grooves, and irregularly shaped holes, to force parts to have a unique installation orientation or position are widely used. The error-proofing boss on the sealing port of automotive engine pipes is a specific application of this error-proofing concept.

[0003] Chinese patent publication number CN218913023U discloses a rubber-plastic composite seal for automotive engines, comprising a first seal, a second seal, a limiting post, and a straight-section support ring. One end of the second limiting ring is rotatably connected to a support shaft. This rubber-plastic composite seal for automotive engines, through the setting of the first limiting ring, enhances the stability between the support cylinder and the second seal. The coordinated arrangement of the arc-shaped plate, the limiting post, and the second support groove achieves a long service life. The support post prevents the third limiting ring from shaking. The coordinated arrangement of the support shaft, the arc-shaped square rod, and the straight-section support ring prevents the components from dispersing.

[0004] However, current engine pipe fitting technology has the following problems: Currently available pipe fittings require accurate connection during assembly; otherwise, it may lead to problems such as engine oil leaks and air leaks. Therefore, we propose a misalignment prevention boss for automotive engine pipe fitting sealing ports. Utility Model Content

[0005] The purpose of this invention is to provide a misalignment prevention boss for the sealing port of an automotive engine pipe, which can solve the problem in related technologies where pipes need to be accurately connected during assembly, otherwise it may lead to problems such as engine oil leakage and air leakage.

[0006] The specific technical solution adopted by this utility model is as follows: A misalignment prevention boss for a sealing port of an automotive engine pipe component includes a first pipe component, a second pipe component disposed on the outside of the first pipe component, and a misalignment prevention connection device disposed inside the first pipe component. The error-proof connection device includes a retainer, which is fixedly connected to the inside of the pipe fitting. The retainer has a groove inside, and a telescopic spring is fixedly connected to the inner wall of the groove. A ball is fixedly connected to the other end of the telescopic spring away from the groove, and the circumferential surface of the ball is slidably connected to the inner wall of the groove.

[0007] The back side of the second pipe fitting is fixedly connected with a buckle, and the side of the buckle is provided with a slot. A sponge pad is fixedly connected to the circumferential surface of the second pipe fitting.

[0008] The number of the ferrule, slot, telescopic spring and ball is set to two, and they are symmetrical to each other along the vertical central axis of the first pipe fitting. The function of the telescopic spring is to reset when no force is applied.

[0009] The ball slides on the inner wall of the slot. There are two slots, which are symmetrical about each other along the vertical central axis of the buckle. The function of the slot is to allow the ball to retract when it is subjected to a squeezing force.

[0010] The outer surface of the pipe fitting is provided with a sealing device, which includes a sealing ring. The sealing ring is disposed on the outer surface of the pipe fitting. A fixing plate is fixedly connected to the circumferential surface of the pipe fitting. A sliding groove is opened on the front side of the fixing plate. A slider is slidably connected to the inner wall of the sliding groove. A support rod is fixedly connected to the top of the slider. A clamping plate is fixedly connected to the top of the support rod.

[0011] The clamping plate has a through groove on its side, and a bolt is threaded to the inner wall of the through groove. A nut is threaded to the circumferential surface of the bolt. A return spring is fixedly connected to the inner wall of the slide groove. The end of the return spring away from the slide groove is fixedly connected to the side of the slider. The function of the slide groove is to support the slider and limit the displacement trajectory of the slider.

[0012] The number of the fixed plate, slide, slider, support rod, clamping plate and return spring is set to two, and they are symmetrical to each other along the vertical central axis of the cable. The number of the through groove, bolt and nut is set to two, and they are symmetrical to each other along the vertical central axis of the pipe fitting. The function of the bolt and nut is to better fix the clamping plate.

[0013] The technical effects achieved by this utility model are as follows: 1. This utility model, through the design of an error-proof connection, allows for the connection of pipe fitting one and pipe fitting two by manually moving the two fittings towards the first fitting. As the two fittings move towards the first fitting, the buckle moves into the first fitting. When the buckle moves, it passes through the middle of the sleeve. When the front end of the buckle passes through the middle of the sleeve, the ball will lock the buckle's groove due to the restoring force of the telescopic spring. This allows for the connection of pipe fitting one and pipe fitting two, thus preventing incorrect assembly problems during the connection process that could lead to engine oil or air leaks, affecting engine performance and reliability.

[0014] 2. This utility model, through its sealed design, ensures that the clamping plate comes into contact with the sealing ring when it moves, thereby clamping the sealing ring. When the clamping plate clamps the sealing ring, it can be fixed by bolts and nuts. By rotating the bolts and tightening the nuts, the two clamping plates can be fixed in place, allowing the clamping plates to better clamp the sealing ring. This ensures the sealing of the connection, avoids insufficient lubrication and cooling failure caused by seal leakage, and ensures stable power output. Attached Figure Description

[0017] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0018] like Figure 1-5 As shown, a misalignment prevention boss for a sealing port of an automotive engine pipe includes a pipe fitting 1, a pipe fitting 2 is provided on the outside of the pipe fitting 1, and a misalignment prevention connection device 3 is provided inside the pipe fitting 1. The error-proof connection device 3 includes a sleeve 31, which is fixedly connected to the inside of the pipe fitting 1. A groove 32 is opened inside the sleeve 31. A telescopic spring 33 is fixedly connected to the inner wall of the groove 32. A ball 34 is fixedly connected to the other end of the telescopic spring 33 away from the groove 32. The circumferential surface of the ball 34 is slidably connected to the inner wall of the groove 32. The back side of the second pipe fitting 2 is fixedly connected with a buckle 35, and the side of the buckle 35 is provided with a slot 36. The circumferential surface of the second pipe fitting 2 is fixedly connected with a sponge pad 37. The number of sleeve 31, groove 32, telescopic spring 33 and ball 34 is set to two, and they are symmetrical to each other along the vertical central axis of pipe fitting 1. The function of telescopic spring 33 is to reset when no force is applied. The ball 34 slides on the inner wall of the slot 32. There are two slots 36, which are symmetrical about each other along the vertical central axis of the buckle 35. The function of the slot 32 is to allow the ball 34 to retract when it is subjected to a squeezing force. Based on the above structure, when connecting engine pipes, the error-proof connection device 3 can be used. By manually moving pipe 2 towards pipe 1, the buckle 35 will move into pipe 1. When the buckle 35 moves, it will pass through the middle of the sleeve 31. When the buckle 35 passes through the middle of the sleeve 31, it will press against the ball 34. When the ball 34 is pressed by the buckle 35, it will retract backward due to the extension spring 33. When the front end of the buckle 35 passes through the middle of the sleeve 31, the ball 34 will lock into the slot 36 of the buckle 35 due to the restoring force of the extension spring 33. Thus, pipe 1 and pipe 2 can be connected, which also prevents incorrect assembly problems during the connection process, which could lead to engine oil leaks, air leaks, etc., affecting the engine's performance and reliability.

[0019] like Figure 1-5 As shown, a sealing device 4 is provided on the outside of the pipe fitting 1. The sealing device 4 includes a sealing ring 41, which is disposed on the outer surface of the pipe fitting 1. A fixing plate 42 is fixedly connected to the circumferential surface of the pipe fitting 1. A sliding groove 43 is provided on the front and side sides of the fixing plate 42. A slider 44 is slidably connected to the inner wall of the sliding groove 43. A support rod 45 is fixedly connected to the top of the slider 44. A clamping plate 46 is fixedly connected to the top of the support rod 45. The clamping plate 46 has a through groove 47 on its side. The inner wall of the through groove 47 is threaded with a bolt 48. The circumferential surface of the bolt 48 is threaded with a nut 49. The inner wall of the slide groove 43 is fixedly connected with a return spring 410. The end of the return spring 410 away from the slide groove 43 is fixedly connected to the side of the slider 44. The function of the slide groove 43 is to support the slider 44 and limit the displacement trajectory of the slider 44. The number of fixed plate 42, slide 43, slider 44, support rod 45, clamping plate 46 and return spring 410 is set to two, and they are symmetrical to each other along the vertical central axis of cable 3. The number of through groove 47, bolt 48 and nut 49 is set to two, and they are symmetrical to each other along the vertical central axis of pipe fitting 1. The function of bolt 48 and nut 49 is to better fix clamping plate 46. According to the above structure, after the pipe fittings are connected, the sealing device 4 can be used. The slider 44 moves inside the groove 43. When the slider 44 moves, it will drive the clamping plate 46 to move through the support rod 45. When the clamping plate 46 moves, it will contact the sealing ring 41, thereby clamping the sealing ring 41. When the clamping plate 46 clamps the sealing ring 41, it can be fixed by bolts 48 and nuts 49. By rotating and tightening the nuts 49 on the bolts 48, the two clamping plates 46 can be fixed, so that the clamping plate 46 can better clamp the sealing ring 41, thereby ensuring the sealing of the connection part, avoiding insufficient lubrication and cooling failure caused by sealing leakage, and ensuring stable power output.
