Description

Technical Field

[0001] This utility model relates to the field of manual fuel station technology, specifically a manual fuel station with quick-release pipeline connection. Background Technology

[0002] Manual grease stations, as a key component of mechanical equipment lubrication systems, primarily deliver lubricating grease to various lubrication points via pipelines through manual operation, ensuring the normal operation and service life of mechanical equipment. Traditional lubrication methods for mining hoists involve handheld grease guns to lubricate the hoist and auxiliary equipment, which suffers from drawbacks such as long operating times and insufficient lubrication. Manual grease stations, with their simple structure, flexible operation, and convenient maintenance, are widely used in scenarios where automatic lubrication is not feasible or where lubrication requirements are low. Therefore, efficient and reliable pipeline connections are crucial for ensuring a stable delivery of lubricating grease by manual grease stations and maintaining the optimal operating condition of mechanical equipment.

[0003] However, traditional manual dry oil stations mostly use welding, threaded connections, or flange connections for pipeline connections. Although welding connections offer high strength, they are difficult to disassemble. If a pipeline malfunctions or requires component replacement, maintenance is cumbersome and time-consuming, and the high temperature of welding can damage the pipeline. Threaded connections are prone to loosening due to vibration and other factors, leading to grease leakage, affecting lubrication, and even causing environmental pollution. Flange connections have problems such as complex structure, large installation space requirements, and high cost. Furthermore, the sealing gaskets are prone to leakage after aging. In practical applications, these traditional connection methods not only reduce the working efficiency of manual dry oil stations and increase maintenance costs and difficulty, but may also lead to accelerated wear of mechanical equipment due to insufficient lubrication, affecting the normal operation and service life of the equipment. Therefore, we propose a manual dry oil station with quick-release pipeline connections. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a manual dry oil station with quick-release pipeline connection, which solves the aforementioned problems.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a quick-release pipe connection manual dry oil station, comprising:

[0006] A manual fuel station, wherein the bottom of the manual fuel station is provided with symmetrically distributed exhaust pipes, and a connecting rigid pipe is inserted inside the exhaust pipe. The first connecting ring and the second connecting ring are semi-circular arc-shaped, and the first connecting ring and the second connecting ring form a complete ring. The ring is fitted onto both ends of the connecting rigid pipe, and one end of the first connecting ring and the second connecting ring is fixedly connected by bolts.

[0007] A fixing assembly is disposed between a first connecting ring and a second connecting ring. The fixing assembly includes a fixing member and a fixing spring, which are installed on both sides of the first connecting ring.

[0008] Preferably, the cylindrical surfaces on both sides of the connecting rigid tube are provided with a plurality of semi-circular friction grooves. One end of the connecting rigid tube is inserted into the interior of the exhaust pipe, and the friction grooves are in close contact with the inner wall of the exhaust pipe. The cylindrical surfaces of the connecting rigid tube are provided with annular grooves on both sides, and the annular grooves are disposed between two friction grooves.

[0009] Preferably, the first connecting ring and the second connecting ring are respectively provided with a semi-circular positioning groove one and a positioning groove two. The end faces of the first connecting ring and the second connecting ring fit together to form a complete ring. The circular grooves on both sides of the connecting tube respectively fit into the positioning groove one and the positioning groove two.

[0010] Preferably, a semi-circular friction block one and a friction block two are fixed on the inner cylindrical surface of the first connecting ring and the second connecting ring. The friction block one and the friction block two correspond to the friction groove on the cylindrical surface of the connecting hard pipe. One end of the connecting hard pipe is located inside the exhaust pipe, and the exhaust pipe is located between the connecting hard pipe and the ring.

[0011] Preferably, a rectangular fixing block is fixedly installed on both sides of the end face of the first connecting ring. The fixing block has a positioning hole inside, and the upper and lower ends of the positioning hole have movable cavities that penetrate both ends of the fixing block. The positioning hole penetrates the end face of the first connecting ring.

[0012] Preferably, the fixing component consists of a fixing member and a fixing spring. The fixing spring is sleeved on the cylindrical surface of the fixing member. The fixing member has a fixing end at its end. The fixing member and the fixing spring are disposed inside the movable cavity, and the fixing end extends through the bottom of the movable cavity to the inside of the positioning hole.

[0013] Preferably, a second fixing block is fixedly installed on both sides of the end face of the second connecting ring, and a positioning block is fixed on the end face of the second fixing block. The positioning block has a fixing hole that passes through the upper and lower ends. The positioning block is inserted into the positioning hole and fixed by the fixing end of the fixing member corresponding to the fixing hole on the positioning block.

[0014] Compared with the prior art, this utility model provides a manual dry oil station with quick-release pipeline connection, which has the following advantages:

[0015] 1. This quick-release manual fuel station features a stable connection. The friction groove on the cylindrical surface of the connecting rigid pipe fits tightly against the inner wall of the exhaust pipe, forming an initial fixation. Simultaneously, the positioning grooves one and two within the first and second connecting rings precisely engage with the circular retaining groove of the connecting rigid pipe, restricting radial movement. The friction blocks one and two on the inner wall are embedded in the friction grooves, further enhancing the connection's stability. Even under complex operating conditions, this ensures a secure connection, preventing loosening or detachment and guaranteeing stable operation of the fuel station. Convenient assembly and disassembly are key features. The fixing components consist of a fixing part and a fixing spring. During connection, the fixing spring's elasticity ensures the connection remains secure. The fixed end automatically inserts into the fixing hole of the positioning block for quick locking. During disassembly, simply pull the fixing piece to overcome the spring force and then unscrew the bolts to easily separate the connecting ring from the connecting rigid pipe. This significantly shortens installation and disassembly time and greatly improves work efficiency, making it particularly suitable for scenarios requiring frequent pipeline disassembly and assembly. In terms of sealing, the cooperation between the friction groove and friction block one and friction block two not only enhances connection stability but also effectively fills gaps, reducing the risk of leakage. The tight contact structure, combined with the insertion design of the exhaust pipe and the connecting rigid pipe, creates a multi-layered sealing protection, ensuring that no leakage occurs during the transmission of dry oil, guaranteeing the effective delivery of dry oil, and preventing dry oil leakage from causing environmental pollution.

[0027] Furthermore, multiple semi-circular friction grooves 10 are formed on the cylindrical surfaces of both sides of the connecting rigid pipe 3. One end of the connecting rigid pipe 3 is inserted into the interior of the exhaust pipe 2, and the friction grooves 10 are tightly fitted with the inner wall of the exhaust pipe 2. Circular ring grooves 9 are formed on both sides of the cylindrical surface of the connecting rigid pipe 3. The circular ring grooves 9 are located between the two friction grooves 10, which increases the friction force during connection, initially fixes the connecting rigid pipe 3, and provides a basis for subsequent positioning and engagement with the connecting ring.

[0028] Furthermore, the first connecting ring 4 and the second connecting ring 5 are respectively provided with a semi-circular positioning groove 11 and a positioning groove 15. The end faces of the first connecting ring 4 and the second connecting ring 5 fit together to form a complete ring. The circular grooves 9 on both sides of the connecting rigid pipe 3 are respectively engaged with the positioning groove 11 and the positioning groove 15, which can effectively restrict the radial movement of the connecting rigid pipe 3 and enhance the stability of the pipeline connection.

[0029] Furthermore, the inner cylindrical surfaces of the first connecting ring 4 and the second connecting ring 5 are fixed with semi-circular friction blocks 12 and 16, which correspond to the friction grooves 10 on the cylindrical surface of the connecting rigid pipe 3. One end of the connecting rigid pipe 3 is located inside the exhaust pipe 2, which is located between the connecting rigid pipe 3 and the ring, further filling the gap, enhancing the sealing and stability of the connection, and preventing the pipe from loosening and liquid leakage.

[0030] Furthermore, rectangular fixing blocks 13 are fixedly installed on both sides of the end face of the first connecting ring 4. The fixing blocks 13 have positioning holes 14 inside. The upper and lower ends of the positioning holes 14 have movable cavities that penetrate both ends of the fixing blocks 13. The positioning holes 14 penetrate the end face of the first connecting ring 4, providing space for the installation and movement of the fixing components. This is an important structural basis for realizing the secure locking of the connecting ring and the connecting rigid tube 3.

[0031] Furthermore, the fixing component consists of a fixing member 6 and a fixing spring 7. The fixing spring 7 is sleeved on the cylindrical surface of the fixing member 6. The end of the fixing member 6 is provided with a fixing end 8. The fixing member 6 and the fixing spring 7 are located inside the movable cavity, and the fixing end 8 extends through the bottom of the movable cavity to the inside of the positioning hole 14 to realize automatic locking of the connecting ring, ensuring the reliability of the connection, and facilitating disassembly.

The positioning block 18 has a fixing hole that passes through the upper and lower ends. The positioning block 18 is inserted into the positioning hole 14. The fixing end 8 at the end of the fixing member 6 is inserted into the fixing hole on the positioning block 18 to fix it. By inserting the fixing end 8 into the fixing hole of the positioning block 18, the two connecting rings are firmly fixed, ensuring the stability of the entire pipeline connection structure.

[0052] Working principle: When connecting the manual fuel station 1 to an external pipeline, first insert one end of the connecting rigid pipe 3 into the exhaust pipe 2 at the bottom of the manual fuel station 1. At this time, the friction groove 10 on the cylindrical surface of the connecting rigid pipe 3 fits tightly with the inner wall of the exhaust pipe 2, increasing the contact friction and initially fixing the position of the connecting rigid pipe 3. Next, the semi-circular first connecting ring 4 and the second connecting ring 5 are respectively fitted onto the two ends of the connecting rigid pipe 3 from both sides, so that the end faces of the first connecting ring 4 and the second connecting ring 5 fit together to form a complete ring. At this time, the ring grooves 9 on both sides of the connecting rigid pipe 3 and the first connecting ring 4 and the second connecting ring 5 fit together to form a complete ring. The positioning grooves 11 and 15, respectively, inside the two connecting rings 5 ​​are precisely aligned to achieve a locking fit, further restricting the radial movement of the connecting rigid tube 3. Simultaneously, the friction blocks 12 and 16 on the inner walls of the first connecting ring 4 and the second connecting ring 5 are embedded in the friction grooves 10 on the cylindrical surface of the connecting rigid tube 3, further enhancing the stability and sealing of the connection. Subsequently, bolts are used to fix one end of the first connecting ring 4 and the second connecting ring 5, completing the initial fixing of the rings. The fixing components play a crucial auxiliary fixing role in this process. The fixing components installed on both sides of the first connecting ring 4... The fastener 6 and the fixing spring 7 are fitted onto the cylindrical surface of the fastener 6. Initially, the fixing spring 7 is compressed, providing a pushing force to the fastener 6 into the positioning hole 14. During the engagement of the first connecting ring 4 and the second connecting ring 5, the positioning block 18 on the fixing block 17 at the end face of the second connecting ring 5 is inserted into the positioning hole 14 of the fixing block 13 of the first connecting ring 4. At this time, under the elastic force of the fixing spring 7, the fixing end 8 at the end of the fastener 6 passes through the movable cavity at the lower end of the positioning hole 14 and is precisely inserted into the fixing hole of the positioning block 18, thus securing the first connecting ring 6. 4 and the second connecting ring 5 are firmly locked, and the connecting hard pipe 3 is also stably fixed to the exhaust pipe 2 of the manual dry oil station 1, forming a stable and reliable connection structure. When it is necessary to disassemble the pipeline, simply pull the fixing part 6 outward to overcome the elastic force of the fixing spring 7, so that the fixing end 8 is disengaged from the fixing hole of the positioning block 18. Then unscrew the bolts at one end of the first connecting ring 4 and the second connecting ring 5, and the first connecting ring 4 and the second connecting ring 5 can be easily removed from the connecting hard pipe 3. Then pull out the connecting hard pipe 3 to complete the quick disassembly operation. The whole process is simple to operate and greatly improves work efficiency.
