Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic hose production, in particular to an anti - detachment structure for a hydraulic hose. Background Technique

[0002] At present, hydraulic hoses, also known as hydraulic oil pipes, hydraulic hoses, high - pressure hoses, hydraulic pipes, steel - wire high - pressure pipes, steel - wire braided hoses, and steel - wire wound hoses, are generally divided into steel - wire braided hydraulic hoses and steel - wire wound hydraulic hoses.

[0003] In related technologies, hydraulic equipment is generally connected by hydraulic hoses. For example, in the hydraulic oil supply pipeline system adopted by a ceramic high - pressure grouting production line, the hydraulic oil in the oil tank is driven by a hydraulic pump and transported to the oil circuit block through a hydraulic hose, with a working pressure as high as 25 Mpa. When connecting the hydraulic hose, the head and tail of the hydraulic hose are provided with metal pressing joints, and the joints are connected by threads.

[0004] In view of the above - mentioned related technologies, the inventor believes that in the high - pressure tensioned state of the hydraulic hose, if the joints age or are disassembled, it is easy to cause the hydraulic hose to burst strongly, resulting in safety accidents. Based on this, the present application proposes an anti - detachment structure for a hydraulic hose to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the shortcomings of the prior art and provide an anti - detachment structure for a hydraulic hose.

[0006] The purpose of the utility model is achieved by the following technical solutions: An anti - detachment structure for a hydraulic hose includes a joint, the middle part of the outside of which is convex. Hose pipes are installed at both ends of the outside of the joint. Flange plates are installed at one ends of the outside of the two hose pipes. A plurality of threaded rods are installed on the outer surfaces on both sides of the convex part of the joint, and they respectively penetrate through the two flange plates. Hoop platforms are formed by outward convexity on both sides of the outside of the joint near the convex part. Hoop seats are sleeved on the outside of the plurality of threaded rods, and the plurality of hoop seats are respectively buckled with the two hoop platforms and enclose a circle. A plurality of uniformly - arrayed anti - retreat inclined plates are installed at both ends of the outside of the joint far from the convex part. The inside of the convex part is hollow to form a liquid storage cavity. A one - way valve is installed on one side inside the liquid storage cavity, and a sampling valve is installed outside the liquid storage cavity.

[0007] Optionally, a plurality of arc - shaped notch openings arranged in a circular array are opened on the outside of the flange plate. The plurality of threaded rods respectively penetrate through the plurality of arc - shaped notch openings, and first locking nuts are threadedly installed on the outside of the plurality of threaded rods and are attached to the outer surface of the flange plate.

[0008] Optionally, a fixed ring plate is installed on one side of the outer surfaces of multiple said ferrule seats. Multiple said threaded rods respectively penetrate through multiple fixed ring plates, and second locking nuts are threadedly installed on the outer parts of multiple said threaded rods, and they are in contact with the outer surface of the fixed ring plate.

[0009] Optionally, an installation hole is formed on one side of the inner wall of the liquid storage cavity. The one-way valve is installed in the installation hole, and the liquid outlet of the one-way valve faces inward.

[0010] Optionally, multiple said anti-retreat inclined plates are all inclined inwards, and their height is not lower than the height of the ferrule platform.

[0011] The utility model has the following advantages:

[0012] For the anti-disconnection structure of the hydraulic hose, two hoses are connected together through a joint. The middle part of the joint is convex, and multiple circumferentially arranged threaded rods are installed on the outer surfaces on both sides of the convex part. One end of the hose is installed with a flange plate, on which multiple circumferentially arranged arc-shaped notch openings are formed. The threaded rods penetrate through the arc-shaped notch openings, so that the joint and the hose can be assembled. After a locking nut is cooperatively installed on the threaded rod, the position of the hose can be fixed, playing a role in primary anti-disconnection, and the hose can also be rotated according to actual situations to avoid position interference between components.

[0013] Among them, a ferrule platform is formed on the outside of the joint near the convex part. Using multiple ferrule seats to externally buckle on the ferrule platform can play a role in secondary anti-disconnection for the hose. And a fixed ring plate is installed on the outside of the ferrule seat. The threaded rod penetrates through the fixed ring plate. While installing a locking nut on the threaded rod to fix the ferrule seat, multiple anti-retreat inclined plates are installed on both sides of the outside of the joint, which can improve the anti-disconnection effect of the hose.

[0014] A liquid storage cavity is formed inside the convex part of the joint. A one-way valve is installed on one side of its inner wall. A sampling valve is installed outside the liquid storage cavity. The liquid flowing through the joint passes through the one-way valve and is discharged from the sampling valve, which is convenient for staff to sample and detect the liquid, greatly increasing the practicability of the whole device.
