AI Technical Summary
Traditional hose connections are prone to fall off during vibration, especially in large pipe diameter pipelines. Due to the thickness of the pipe wall and limited clamp strength, the dual action of external vibration and internal fluid pressure, the rubber hose is more likely to fall off, reducing system reliability and causing economic losses.
A steel pipe connecting device is designed, including a first pipe fitting and a second pipe fitting, and a stable connection is achieved through a connecting pipe, a sealing groove, a sealing block, a connecting piece and a connecting mechanism. The connecting mechanism consists of a movable ring, a fixed block, a movable rod, a support spring, a top block, a limit block and a limit slot. The stable connection of the pipe fittings is achieved by rotating the movable ring, extruding the top block, pushing the movable rod and a limit block into the limit slot, so as to achieve a stable connection of the pipe fittings.
The device has high connection mode, which can effectively prevent the hose from falling off after the connection is completed, and it is simple and convenient to operate, improving the reliability and efficiency of the system.

[0002] A pipeline is a device connected by pipes, pipe connectors and valves for conveying gas, liquid or fluid with solid particles. Usually, the fluid is pressurized by blowers, compressors, pumps and boilers, and then flows from the high-pressure part of the pipeline to the low-pressure part. The fluid can also be conveyed by its own pressure or gravity. Pipelines are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial installations.
[0003] Traditional hose connections are mostly clamped and fixed with clamps, but during vibration, rubber hoses can easily come off, especially for large-diameter pipelines. Due to the thick pipe wall, the pipe mouth cannot be rolled, the strength of the clamp is limited, and the transported fluid (oil, water, gas) has a certain pressure. Under the dual effects of external vibration and internal fluid pressure, the rubber hose will be more likely to fall off, which will reduce the working reliability of the entire system and cause certain economic losses to users.

DETAILED DESCRIPTION
[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.
[0018] See also Figure 1-3 In this embodiment, a steel pipe connecting device capable of preventing a hose from falling off comprises a first pipe fitting 1, a second pipe fitting 2 is arranged on the right side of the first pipe fitting 1, a connecting pipe 3 is fixed on the side opposite to the first pipe fitting 1 and the second pipe fitting 2, a sealing groove 4 is provided on the right side of the left connecting pipe 3, a sealing block 5 is fixed on the left side of the right connecting pipe 3, a connecting piece 6 is arranged outside the connecting pipe 3, circular holes 7 are provided on the left and right sides of the connecting piece 6, and a connecting mechanism 8 is arranged on the connecting piece 6.
[0019] It should be noted that the provision of the sealing groove 4 of the sealing block can improve the sealing performance after the first pipe 1 and the second pipe 2 are connected.
[0020] See also Figure 1-3 In order to improve the stability of the connection between the first pipe fitting 1 and the second pipe fitting 2 and improve the convenience of operation, the connecting mechanism 8 includes a movable ring 801 threadedly connected to the left and right sides of the outer surface of the connecting member 6, and a fixing block 802 is fixed on the opposite side of the inner wall of the two movable rings 801. The connecting mechanism 8 also includes a plurality of fixing holes 803 opened on the left and right sides of the outer surface of the connecting member 6, and a movable rod 804 is slidably connected in the fixing hole 803. A support spring 805 is movably sleeved on one side of the outer surface of the movable rod 804 close to the movable ring 801, a top block 806 is fixed to the end of the movable rod 804 close to the movable ring 801, and a limiting block 807 is fixed to the end of the movable rod 804 away from the top block 806. The connecting mechanism 8 also includes a plurality of limiting grooves 808 opened on the outer surface of the connecting pipe 3 close to the limiting block 807.
[0021] The connecting tube 3 is a circular tube, and the two connecting tubes 3 are respectively inserted into the two circular holes 7 and are clearance-matched therewith, so that the gap between the connecting tube 3 and the connecting piece 6 is smaller and the stability after connection is higher.
[0022] At the same time, the sealing groove 4 is an annular groove, and the sealing block 5 is an annular sealing block. The sealing block 5 is inserted into the sealing groove 4 and matched with the gap therein, which can improve the sealing between the first pipe fitting 1 and the second pipe fitting 2 and is beneficial to the subsequent transportation.
[0023] In addition, the side of the top block 806 away from the support spring 805 is tightly fitted with the fixed block 802 , and the fixed block 802 is in the shape of a ring-shaped inclined surface, which makes it easy to push the top block 806 to move through the fixed block 802 .
[0024] It can be understood that the two ends of the support spring 805 are respectively abutted between the fixed block 802 and the connecting piece 6, and the two movable rings 801 are symmetrically distributed on the left and right. The elasticity of the support spring 805 can also make the limit block 807 automatically move out of the limit groove 808, which is conducive to improving the convenience of operation.
[0025] Finally, the number of limit blocks 807 and limit grooves 808 is equal. The limit blocks 807 enter and exit the limit grooves 808 and cooperate with the clearance therein. The limit grooves 808 are evenly distributed on the outer surface of the connecting pipe 3 in a circular ring shape, so that the limit blocks 807 can be accurately inserted into the limit grooves 808, and the operation is more efficient and convenient.
[0026] The working principle of the above embodiment is as follows: when connecting the first pipe 1 with the second pipe 2, first insert the connecting pipe 3 on the first pipe 1 into the left side of the connecting piece 6, and then insert the connecting pipe 3 on the second pipe 2 into the right side of the connecting piece 6. During this process, the sealing block 5 is inserted into the sealing groove 4, thereby improving the sealing between the first pipe 1 and the second pipe 2. Then, the two movable rings 801 are rotated to move to the opposite side. During the movement, the top block 806 is squeezed by the fixed block 802, and the movable rod 804 is pushed by the top block 806 to move to the side close to the connecting pipe 3. At the same time, the limit block 807 is inserted into The limiting groove 808 fixes the first pipe fitting 1 and the second pipe fitting 2 together. Since the top block 806 squeezes the supporting spring 805 and gives it elastic potential energy during the process of pushing the movable rod 804, when the two movable rings 801 are rotated to move to the opposite side, the top block 806 is not pushed by the fixed block 802. Therefore, the limiting block 807 can be moved out of the limiting groove 808 under the action of the elastic potential energy of the supporting spring 805, so that the first pipe fitting 1 and the second pipe fitting 2 can be quickly disassembled. The operation is simple and convenient, and it can prevent the hose from falling off after the connection is completed, which is more practical.
