Description

Technical Field

[0001] The invention relates to the technical field of rubber hoses, and in particular to an anti-aging rubber hose for an engine. Background Art

[0002] In the engine's operating system, hoses, as key components for transporting liquids or gases, play an indispensable role. Traditional engine hose connection technology has long had many drawbacks and is unable to meet the stringent requirements of modern engines for stability, durability, and safety under complex operating conditions.

[0003] Conventional hose connection methods in the past mostly relied on clamps to achieve fixation and sealing with the engine. This type of clamp usually has a square hole design, and its original intention was to facilitate tightening operations. However, in actual use scenarios, especially when the engine is in a high-temperature working environment, the metal clamp expands due to heat, and the hole wall of the square hole will inevitably exert concentrated and uneven pressure on the outer wall of the hose. Long-term operation of the engine is also accompanied by high-frequency vibration. Under this working condition, this uneven pressure will continuously impact the same position of the hose, causing the outer wall of the hose to be easily crushed, thereby destroying the overall structural integrity of the hose, greatly accelerating the aging process of the hose, and seriously shortening the service life of the hose.

[0004] Moreover, the contact between the traditional clamp and the hose or the matching connecting pipe is mostly linear contact, with limited contact area, and it is difficult to ensure the sealing effect. Once the seal is not good, the transported liquid or gas is prone to leakage, which not only wastes energy, but also may cause safety hazards due to the contact between the leaked material and the high-temperature parts of the engine. For example, fuel leakage may cause fire accidents, and coolant leakage may cause engine overheating and damage. Summary of the invention

[0019] As a further technical solution, the rotating member has an abutment portion, and the first fixed member and the second fixed member both have a clearance groove. After the rotating member rotates, a fixed space is formed between the abutment portion and the clearance groove, and the locking member has a locking portion, which extends into the fixed space and is used to lock the rotating member.

[0020] As a further technical solution, the first fixing member, the second fixing member, and the clamping strip are arranged in a plurality of rows, the entrance of the adjacent installation cavity leads to the exit of another installation cavity, and the annular portion is arranged in a plurality of rows, and the plurality of the annular portions are respectively located in a plurality of the installation cavities.

[0021] As a further technical solution, the locking piece is slidably arranged on the connecting piece, the first fixing piece and the second fixing piece away from the end of the hose both have a first sliding groove, the locking piece has a sliding portion, and the sliding portion is slidably arranged in the first sliding groove, and the locking piece is configured so that after the clamping bar clamps the hose, the locking portion is inserted into the fixed space.

[0027] The working principle and beneficial effects of the present invention are:

[0028] In the present invention, the hose is the main part of the whole system, which is used to transport liquid or gas. The hose is made of aging-resistant materials to ensure that it can maintain good performance and life in high temperature, high pressure and chemical corrosion environment. The locking tube sleeve is arranged on the outside of the hose for connecting with the engine. The design of the locking tube ensures the tight connection between the hose and the engine interface to prevent leakage. The connecting piece is arranged on the locking tube to fix the clamping strip and other related parts. The connecting piece is usually made of metal material with high strength and corrosion resistance to ensure reliability for long-term use. Both ends of the clamping strip are arranged on the connecting piece and are pressed on the locking tube in an arc shape. The clamping strip has an arc groove, which faces the side away from the axis of the hose. After the clamping strip is tightened, the locking tube and the hose can be firmly fixed to the engine to prevent loosening and leakage. The locking piece is used to further fix the clamping strip to ensure that it can remain tightened under vibration and impact conditions.

[0029] The design of the arc-shaped clamping strip allows the clamping force to be evenly distributed on the locking tube, rather than concentrated at a certain point or edge, thereby reducing local pressure on the hose and avoiding local damage. Compared with the clamping hoop of the prior art, the arc-shaped clamping strip does not have a square hole designed for easy tightening, which avoids the hole wall of the square hole pressing the hose, thereby preventing the outer wall of the hose from being crushed under high temperature and high-frequency vibration, and slowing down the aging of the hose. The design of the arc-shaped clamping strip allows the clamping strip to exert more uniform pressure on the locking tube, reducing damage to the locking tube by the edge of the clamping strip and extending the service life of the locking tube. When there is no locking tube, the arc-shaped clamping strip can be directly pressed onto the hose, effectively reducing the damage to the hose caused by the clamping strip, thereby reducing the accelerated aging of the hose caused by damage to the outer surface.

[0030] The arc design of the clamping strip increases the contact area with the locking tube, improves the sealing, and effectively prevents liquid or gas leakage. The combined design of the locking piece and the clamping strip ensures the stability of the connection and can remain tight even under vibration and impact conditions.

In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0048] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0050] Reference Figure 1 to Figure 13 , which is the first embodiment of the present invention, proposes an aging-resistant hose for an engine, including a hose 1, a locking tube 2 arranged at the end of the hose 1 for connecting to the engine, a connecting piece 3 arranged on the locking tube 2, both ends of a clamping strip 4 are arranged on the connecting piece 3, the clamping strip 4 is an arc-shaped strip, pressed on the locking tube 2, the clamping strip 4 has an arc-shaped groove 401, the arc-shaped groove 401 faces away from the axis of the hose 1, and the back side is pressed on the hose 1, and the locking piece 5 is arranged on the connecting piece 3 and is located on one side of the connecting piece 3.

[0051] In this embodiment, the hose 1 is the main part of the whole system, which is used to transport liquid or gas. The hose 1 is made of aging-resistant materials to ensure that it can maintain good performance and life in high temperature, high pressure and chemical corrosion environments. The locking tube 2 is sleeved on the outside of the hose 1 for connection with the engine. The design of the locking tube 2 ensures the tight connection between the hose 1 and the engine interface to prevent leakage. The connector 3 is arranged on the locking tube 2 to fix the clamping strip 4 and other related components. The connector 3 is usually made of metal material with high strength and corrosion resistance to ensure long-term reliability. Both ends of the clamping strip 4 are arranged on the connector 3 and are pressed on the locking tube 2 in an arc shape. The clamping strip 4 has an arc groove 401, which faces the side away from the axis of the hose 1. After the clamping strip 4 is tightened, the locking tube 2 and the hose 1 can be firmly fixed on the engine to prevent loosening and leakage. The locking piece 5 is used to further fix the clamping strip 4 to ensure that it can remain in a tight state under vibration and impact conditions.

[0052] The design of the arc-shaped clamping strip 4 makes the clamping force evenly distributed on the locking tube 2, rather than concentrated at a certain point or edge, thereby reducing the local pressure on the hose 1 and avoiding local damage. Compared with the clamping hoop of the prior art, the arc-shaped clamping strip 4 does not have a square hole designed for easy tightening, which avoids the hole wall of the square hole pressing the hose 1, thereby preventing the outer wall of the hose 1 from being crushed under high temperature and high-frequency vibration, and slowing down the aging speed of the hose 1. The design of the arc-shaped clamping strip 4 makes the pressure of the clamping strip 4 on the locking tube 2 more uniform, reduces the damage to the locking tube 2 by the edge of the clamping strip 4, and extends the service life of the locking tube 2. When there is no locking tube 2, the arc-shaped clamping strip 4 can be directly pressed on the hose 1, effectively reducing the damage caused by the clamping strip 4 to the hose 1, thereby reducing the accelerated aging of the hose 1 caused by damage to the outer surface.

[0053] The arc-shaped design of the clamping strip 4 increases the contact area with the locking tube 2, improves the sealing performance, and effectively prevents liquid or gas leakage. The combined design of the locking piece 5 and the clamping strip 4 ensures the stability of the connection and can maintain a tight state even under vibration and impact conditions.

[0054] Further, the connecting member 3 includes a first fixing member 301, which is arranged on the locking tube 2. The first fixing member 301 has an arc-shaped limit groove 3011. There are two arc-shaped limit grooves 3011, which are respectively located on both sides of the first fixing member 301. The second fixing member 302 is arranged on the first fixing member 301. An installation cavity 303 is formed between the first fixing member 301 and the second fixing member 302. The installation cavity 303 has an entrance 304 and an exit 305. The arc-shaped limit groove 3011 leads to the installation cavity 303. The rotating member 306 is rotatably arranged in the installation cavity 303. The rotating member 306 has a fixing groove 3061. There are several fixing grooves 3061. Both ends of the clamping strip 4 pass through an arc-shaped limit groove 3011 and a fixing groove 3061.

[0055] In this embodiment, two arc-shaped limit grooves 3011 are symmetrically distributed on both sides of the first fixing member 301 and meet the requirement of the clamping bar 4 passing through. The second fixing member 302 is assembled and connected with the first fixing member 301 by bolts. During assembly, it fits tightly with the first fixing member 301 to form a complete installation cavity 303 with an entrance 304 and an exit 305. The rotating member 306 is arranged in the installation cavity, and multiple fixed grooves 3061 are arranged in order along the rotating member 306, so that both ends of the clamping bar 4 can be accurately inserted.

[0056] The connector 3 is assembled with bolts, which greatly simplifies the assembly process. Compared with traditional complex welding or riveting methods, bolt assembly does not require professional welding equipment and difficult operating skills. Ordinary maintenance personnel can quickly and accurately connect the first fixing member 301, the second fixing member 302 and related accessories with simple tools such as conventional wrenches according to the pre-drilled holes and threaded designs. In the rapid assembly link of the engine production line, or in the scenarios of daily equipment maintenance and hose replacement, the assembly time is greatly shortened, work efficiency is improved, and the equipment downtime caused by time-consuming assembly is reduced, which meets the needs of efficient production and operation.

[0057] The bolt assembly ensures the convenience and versatility of the connector 3 without sacrificing structural stability. When the engine is subjected to complex working conditions such as vibration, impact, and temperature changes, the components fit tightly and work together to firmly fix the clamping strip 4, so that the hose 1 and the engine interface always maintain a high-strength connection state, eliminating the potential for loosening and leakage, ensuring the safe and stable transmission of liquid or gaseous media in the hose, and ensuring stable and efficient operation of the engine.

[0058] When the rotating member 306 rotates to the specified position, the clamping strip 4 is tightly wound around its periphery, forming a physical connection structure similar to "encircling reinforcement". This winding method significantly increases the contact area between the clamping strip 4 and the rotating member 306, and the pressure distribution is more uniform, which effectively disperses the tightening force borne by the hose 1 and the locking tube 2, avoids the occurrence of stress concentration points, and reduces the risk of component wear, deformation, or even damage due to excessive local force. At the same time, the locking operation of the rotating member 306 is implemented with the help of the locking member 5, which further enhances the mechanical stability. Even in extreme scenarios where the engine encounters high-intensity vibrations such as high-frequency and large-amplitude vibrations generated when the engine is running at high speed, and the instantaneous impact force caused by sudden acceleration and sudden braking of the vehicle is transmitted to the engine connection part, the relative positions between the components are still stable, which effectively guarantees the reliability of the connection between the hose 1 and the engine interface, prevents undesirable phenomena such as loosening and displacement, and lays a solid foundation for the stable operation of the engine system.

[0059] The clamping bar 4 is wrapped around the rotating part 306 and is firmly locked in a stable structure, which plays a key supporting role in the sealing of the connection between the hose 1 and the engine. During the operation of the engine, whether it is transporting liquid media such as fuel and coolant, or transmitting gaseous media such as exhaust gas, the tight and stable connection structure can effectively prevent the leakage of the medium. During long-term operation, the sealing performance of traditional hose connections is prone to gradual decline due to factors such as vibration and aging. However, this design relies on the unique synergistic mechanism of the rotating part 306 and the clamping bar 4 to continuously maintain a good sealing state, reduce the risk of environmental pollution caused by medium leakage, energy waste problems and possible engine failure hazards, greatly improve the engine's working safety and environmental protection, extend the stable operation cycle of the equipment, and reduce the frequency and cost of operation and maintenance.

[0060] Furthermore, the rotating member 306 has an annular portion 3062, which is located in the installation cavity 303. The fixing groove 3061 passes through the annular portion 3062. The annular portion 3062 has two fixing grooves 3061. After the rotating member 306 rotates, the clamping bar 4 is tightened, and the arc groove 401 at one end of the clamping bar 4 presses the other end of the clamping bar 4 onto the annular portion 3062.

[0061] In this embodiment, the annular portion 3062 of the rotating member 306 is combined with a unique tightening method of the clamping strip 4 to construct an extremely stable connection structure. When the rotating member 306 rotates to cause the clamping strip 4 to tighten, the arc groove 401 of the clamping strip 4 at one end presses the clamping strip 4 at the other end on the annular portion 3062. This design cleverly utilizes the principle of mechanical interaction. With the help of the fit and compression of the arc groove 401, the clamping strips 4 at both ends are closely related and coordinated. Compared with the conventional single-direction clamping method, the clamping and tightening force on the locking tube 2 is greatly enhanced. During the entire operation of the engine, whether it is facing high-frequency vibration: such as periodic vibration generated by high-speed rotation of the engine, or encountering sudden and severe impacts such as sudden collisions, sudden braking, and other extreme situations during vehicle driving, the external force impact transmitted to the engine, the structure can rely on its own stable characteristics to firmly connect the hose 1 to the engine, effectively eliminate the risk of loosening and separation, ensure stable transmission of the medium, and extend the time for the hose system to withstand complex working conditions, so as to "escort" the long-term reliable operation of the engine.

[0062] This structure in which one end of the clamping strip 4 is pressed onto the annular portion 3062 with the aid of the arc groove 401 has an outstanding sealing and protective effect on the connection between the hose 1 and the engine. In the tightened state, the clamping strips 4 at both ends fit tightly against the annular portion 3062, and the seamless docking makes it almost impossible for the liquid or gas medium to leak. In view of the operating requirements of strictly preventing and controlling fuel leakage when transporting fuel to the engine and preventing coolant from overflowing when transporting coolant, even in complex situations such as the engine running for a long time causing thermal expansion and contraction of components, and frequent operating condition switching causing pressure fluctuations, it can still maintain a reliable sealing state, greatly reducing energy waste and environmental pollution caused by leakage, as well as potential hidden dangers of engine combustion abnormalities, overheating damage, etc., which meets the requirements of green, efficient, and safe operation of the engine, and enhances the overall stability and durability of the equipment.

[0063] Furthermore, the side walls of the inlet 304 and the outlet 305 are each provided with a guide groove 307 , and the rotating member 306 is provided with a rotating portion 3064 , and the rotating portion 3064 is rotatably disposed in the guide groove 307 .

[0064] In this embodiment, the guide groove 307 provided on the side wall of the inlet 304 and the outlet 305 cooperates with the rotating part 3064 of the rotating member 306 to construct a smooth and precise running track for the rotation operation. When the engine operating conditions change frequently and it is necessary to adjust the tightening degree of the clamping bar 4 to adapt to different working conditions, the rotating part 3064 rotates along the guide groove 307, effectively limiting the degree of freedom of the rotating member 306 and avoiding unnecessary deviation, shaking or jamming. The guide groove 307 is like a guide rail, ensuring that each rotation action is carried out stably along the preset path, so that the clamping bar 4 can accurately and smoothly change the tightening or loosening state, ensuring that the stability of the connection between the hose 1 and the engine is not affected during the dynamic adjustment process, thereby maintaining the continuous and reliable transportation of the engine medium, reducing the risk of connection failure due to abnormal rotation, and at the same time, after the first fixing member 301 is connected to the second fixing member 302, the first fixing member 301 and the second fixing member 302 position the rotating member 306.

[0065] The guide structure greatly enhances the overall mechanical stability of the connector 3. Since the rotating part 3064 is firmly constrained in the guide groove 307, even if the engine encounters high-intensity vibration, such as the engine vibrating violently when the vehicle is driving on a rough road, or the high-frequency jitter caused by the high-speed operation of the engine, the rotating part 306 can rely on the guide groove 307 to maintain its original position and stably bear the force, avoiding additional wear, deformation or damage to itself and the connected clamping strip 4, the first fixing part 301 and the second fixing part 302 due to disordered shaking. During long-term operation, it effectively slows down the aging speed of the components, prolongs the service life of the connector 3 and even the entire hose system, reduces the frequency and cost of equipment maintenance, improves the overall durability of the equipment, and lays a solid foundation for the long-term and stable operation of the engine.

[0066] For maintenance personnel or operators, the design of the guide groove 307 and the rotating part 3064 significantly improves the convenience of operation. When performing hose connection adjustment, daily maintenance or emergency repair, it is only necessary to simply rotate the rotating part 306, and with the help of the clear and definite guidance of the guide groove 307, the tightening or loosening operation of the clamping bar 4 can be easily and quickly realized without the assistance of complex tools or precise alignment operations. This not only saves operation time and reduces labor intensity, but also can respond in time in emergency situations to ensure that the engine quickly returns to the best operating state.

[0067] Furthermore, the rotating member 306 has an abutment portion 3063, and the first fixing member 301 and the second fixing member 302 both have a clearance groove 3021. After the rotating member 306 rotates, a fixed space 3022 is formed between the abutment portion 3063 and the clearance groove 3021. The locking member 5 has a locking portion 501, which extends into the fixed space 3022 for locking the rotating member 306.

[0068] In this embodiment, the abutment portion 3063 of the rotating member 306 cooperates with the clearance grooves 3021 of the first fixing member 301 and the second fixing member 302 to form a dedicated fixed space 3022 after being rotated and adjusted into place, for the locking portion 501 of the locking member 5 to be embedded and locked, thereby constructing an extremely stable mechanical locking structure. This design fully considers the complexity and severity of the engine operating environment. Whether it is continuous high-frequency vibration, such as the regular shaking generated when the engine runs at high speed for a long time, or encountering sudden and strong impacts, such as the external force transmitted to the engine by emergency braking or collision of the vehicle, the locking portion 501 can tightly restrain the rotating member 306 in the fixed space 3022, so that it maintains a predetermined position, and prevents loosening and displacement caused by external interference. In this way, it is ensured that the holding strip 4 always maintains a stable tightening state, firmly connects the hose 1 to the engine, lays a solid foundation for the stable and safe transmission of the medium, greatly prolongs the time the hose system can withstand harsh working conditions, and ensures long-term reliable operation of the engine.

[0069] By cleverly setting the abutment portion 3063, the clearance groove 3021 and the matching locking mechanism, the entire connection structure is endowed with excellent precision adaptation capability and flexible adjustment characteristics. When the engine is switched between different operating conditions, maintenance personnel or operators can rotate the rotating member 306 as needed to accurately change the tightening degree of the clamping bar 4, and after adjusting to the ideal state, use the locking member 5 to quickly lock it.

[0070] The stable locking structure effectively disperses and buffers the external forces applied to various components during the operation of the engine, reducing the risk of component wear and deformation caused by frequent vibration and impact. Under reliable locking, the rotating member 306, the first fixing member 301, the second fixing member 302 and the locking member 5 work together more stably and orderly, the aging speed is slowed down, and the frequency of replacement and maintenance due to component damage is reduced.

[0071] Furthermore, the first fixing member 301, the second fixing member 302, and the clamping strip 4 are arranged in a plurality, the entrance 304 of the adjacent installation cavity 303 leads to the exit 305 of another installation cavity 303, and the annular portion 3062 is arranged in a plurality, and the plurality of annular portions 3062 are respectively located in a plurality of installation cavities 303.

[0072] In this embodiment, a plurality of first fixing members 301, second fixing members 302, clamping strips 4 and annular portions 3062 are arranged in sequence to construct a distributed and coordinated stable connection system. Compared with a single connection structure, this design of multiple groups arranged in parallel greatly enhances the overall strength and stability of the connection between the hose 1 and the engine. When the engine is running at high intensity and produces severe vibrations, or encounters sudden impact forces such as when the vehicle is driving on bumpy roads, rapid acceleration and sudden braking, each connection unit evenly disperses the external force, effectively preventing excessive local stress from causing loosening and damage to components, ensuring that the hose 1 is always tightly and reliably attached to the engine interface, ensuring stable and uninterrupted transmission of the medium, and laying a solid foundation for the long-term safe operation of the engine.

[0073] Multiple sets of connection structures are arranged in parallel with inherent redundancy. Even if a set of components, such as a clamping bar 4, a rotating part 306 or a fixed part, is accidentally damaged or degraded, the remaining healthy units can still maintain basic connection functions and sealing, ensuring the normal operation of the engine and avoiding the shutdown of the entire machine due to local failures. In daily equipment maintenance and troubleshooting, the problem unit can be repaired and replaced at a fixed point without disassembling the hose system as a whole, greatly shortening the maintenance time, reducing labor intensity and operation and maintenance costs.

[0074] Furthermore, the locking member 5 is slidably arranged on the connecting member 3, and the first fixing member 301 and the second fixing member 302 away from the end of the hose 1 both have a first sliding groove 3023, and the locking member 5 has a sliding portion 502, and the sliding portion 502 is slidably arranged in the first sliding groove 3023. The locking member 5 is configured so that after the clamping strip 4 clamps the hose 1, the locking portion 501 is inserted into the fixed space 3022.

[0075] In this embodiment, the design that the locking member 5 is slidably arranged on the connecting member 3 greatly optimizes the locking operation process. When it is necessary to fasten the hose 1 to the engine, the maintenance personnel only need to push the locking member 5 so that the sliding part 502 slides smoothly along the first slide groove 3023 to achieve the fixing of the first fixing member 301 and the second fixing member 302 at the end. After fixing, the rotating member 306 is rotated until the clamping bar 4 clamps the hose 1 to a suitable degree, and the locking member 5 is continued to be pushed to slide, so that the locking part 501 can be accurately inserted into the fixing space 3022, and the locking of the rotating member 306 is completed, thereby stabilizing the entire connection structure. After the locking is completed, the first fixing member 301, the second fixing member 302 and the locking member 5 are further connected and fixed by bolts. This sliding design avoids complex alignment operations and improves assembly efficiency. Especially in scenarios with high efficiency requirements such as engine assembly production lines, it can significantly shorten the assembly time of the hose connection.

[0076] During equipment maintenance and overhaul, the operation of the sliding locking member 5 is easier. Maintenance personnel can easily release or adjust the connection state by sliding the locking member 5, which is convenient for checking, replacing or repairing the hose 1, the clamping bar 4 and other components without complicated disassembly and reassembly processes, further reducing the difficulty and cost of operation and maintenance, and improving the maintainability and overall operation efficiency of the equipment.

[0077] Furthermore, it also includes a mounting member 6, which is arranged on the connecting member 3 and is located at an end away from the locking member 5. The rotating member 306 passes through the mounting member 6, and the mounting member 6 has a second slide groove 601. The sliding member 7 has a sliding portion 701, and the sliding portion 701 is slidably arranged in the second slide groove 601. There are two sliding members 7, which are respectively arranged on both sides of the second slide groove 601. The sliding member 7 has a contact surface 702 and an arc-shaped giving way surface 703. After the rotating member 306 rotates, the contact surface 702 contacts or cancels the contact with the contact portion 3063, and the arc-shaped giving way surface 703 contacts or cancels the contact with the rotating portion 3064.

[0078] In this embodiment, the mounting member 6 serves as the positioning cornerstone of the sliding member 7. With the help of the second slide groove 601, a clear and stable motion trajectory is defined for the sliding member 7. The sliding member 7 serves to guide the unidirectional rotation of the rotating member 306. With the help of the ingenious matching mechanism between the abutment surface 702 and the abutment portion 3063 of the rotating member 306 and the arc-shaped yielding surface 703 and the rotating portion 3064, the unidirectional rotation characteristic of the rotating member 306 provides great convenience for the operator. When it is necessary to tighten the clamping strip 4 to strengthen the connection between the hose 1 and the engine, the operator only needs to rotate the rotating member 306 in a single direction. This unidirectional rotation design avoids confusion of direction during operation, and there is no need to worry about the clamping strip 4 failing to tighten normally or becoming loose due to the wrong rotation direction.

[0079] Compared with structures without one-way rotation restrictions, operators do not need to spend extra time to determine the correct direction of rotation, and the possibility of repeated adjustments due to operational errors is also reduced. For example, when reconnecting the hose 1 after engine repair or regular maintenance, the one-way rotating rotating part 306 allows the operator to quickly and accurately complete the tightening operation of the clamping strip 4, significantly improving work efficiency. Because the one-way rotation makes the tightening operation more convenient, the operator can more efficiently tighten the clamping strip 4 to the appropriate degree to ensure a tight and stable connection between the hose 1 and the engine. During engine operation, this tight connection is crucial to preventing media leakage and maintaining system stability. After the installation is completed, the mounting part 5 can be removed and reused, further saving related costs.

[0080] Furthermore, the sliding member 7 has an arcuate guide surface 704, the arcuate guide surface 704 is connected to the abutment surface 702, the abutment surface 702 is connected to the arcuate yielding surface 703, and the rotating member 306 is configured so that when the rotating member 306 rotates forward, the rotating portion 3064 passes through the abutment surface 702 and the arcuate yielding surface 703 in sequence, and when the rotating member 306 reverses, the abutment portion 3063 abuts against the abutment surface 702.

[0081] In this embodiment, the arc-shaped guide surface 704 provided on the sliding member 7 is connected with the abutment surface 702 and the arc-shaped clearance surface 703, providing an extremely accurate guide path for the rotation of the rotating member 306. When the operator needs to tighten the holding bar 4, that is, when the rotating member 306 rotates forward, the rotating portion 3064 can pass through the arc-shaped guide surface 704, the abutment surface 702 and the arc-shaped clearance surface 703 in sequence. This design makes the rotation process like moving along a preset track, effectively avoiding the rotating member 306 from deviating from the correct path or getting stuck during the rotation process, and greatly improving the smoothness and accuracy of the rotation operation.

[0082] This precise guidance further enhances the convenience of operation. The operator only needs to rotate the rotating member 306 in the specified forward direction, without worrying about complex adjustments or direction control during the rotation process, and can complete the tightening operation of the clamping bar 4 more easily and quickly, which significantly improves work efficiency, especially in scenarios such as engine assembly production lines or equipment maintenance sites where high operating speed and accuracy are required. The advantages are more obvious.

[0083] When the rotating member 306 is reversed, the design of the abutment portion 3063 abutting against the abutment surface 702 plays a key role in limiting the rotation. This mechanism effectively prevents the rotating member 306 from rotating in an unexpected direction, ensures that the tightening operation of the clamping bar 4 can only be performed in the prescribed forward direction, and avoids the loosening of the clamping bar 4 or the unstable connection state due to misoperation.

[0084] Furthermore, the mounting member 6 has a fixed end 602 which is inserted into the guide groove 307 . There are two fixed ends 602 . The distance between the two fixed ends 602 is greater than the diameter of the rotating member 306 . The mounting member 6 has a through hole 603 which leads to the inlet 304 . The rotating member 306 has a straight groove 308 .

[0085] In this embodiment, the design of inserting the fixed end 602 of the mounting member 6 into the guide groove 307 provides a very stable positioning effect for the mounting member 6 itself. The two fixed ends 602 are respectively embedded in the guide groove 307, just like the positioning pins embedded in the track, which accurately determine the position of the mounting member 6 and effectively prevent it from being displaced or shaken due to external forces such as vibration and impact during the operation of the engine. This stable positioning not only ensures the stability of the mounting member 6 itself, but also lays the foundation for the reliability of the sliding member 7 connected thereto and the entire connection structure.

[0086] At the same time, since the distance between the two fixed ends 602 is greater than the diameter of the rotating member 306, while ensuring that the mounting member 6 is firmly installed, sufficient space is reserved for the rotation of the rotating member 306, so that it can rotate smoothly under the constraint of the mounting member 6, avoiding interference or jamming due to insufficient space, further strengthening the mechanical properties of the entire connection structure, and ensuring the stability of the connection between the hose 1 and the engine, so that it can still operate reliably under complex and changeable engine operating conditions.

[0087] The through hole 603 provided in the mounting member 6 leads to the inlet 304, which greatly facilitates the operator in operating the rotating member 306. The operator can directly observe the inlet 304 and part of the internal structure through the through hole 603, so as to more accurately understand the position and state of the rotating member 306.

[0088] In addition, the slot 308 of the rotating member 306 further facilitates the operation. The operator can use a suitable tool such as a slotted screwdriver to insert the slot 308, and then rotate the rotating member 306 in the required direction. This operation method is simple and direct, and does not require complex auxiliary equipment or special skills. In scenarios such as engine maintenance and debugging, the connection state of the hose 1 can be adjusted quickly and efficiently, thereby improving the operation and maintenance efficiency.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
