Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydraulic pipe fitting technology, specifically a leak-proof hydraulic pipe fitting. Background Technology
[0002] Hydraulic pipe fittings are components used in hydraulic systems to connect high-pressure oil pipes to each other. They can also connect different hydraulic components (such as pumps, delivery lines, directional valves, shut-off valves, hydraulic motors, hydraulic cylinders, etc.) to form a closed-loop hydraulic system. Hydraulic pipe fittings ensure a firm and reliable connection between oil pipes or hydraulic components through different connection methods and sealing structures.
[0003] Existing hydraulic pipe fittings often result in insecure connections during assembly, leading to gaps and leaks. Therefore, we propose a leak-proof hydraulic pipe fitting to address these issues. Utility Model Content
[0004] Purpose of the utility model: In view of the problem that hydraulic pipe joints in the prior art are not securely connected during the connection process, which can easily lead to gaps at the joint and leakage, this utility model proposes a leak-proof hydraulic pipe joint.
[0005] Technical solution: A leak-proof hydraulic pipe fitting includes a pipe body, a fitting, and a mating block. The fitting is located at the front end of the pipe body and is mated with the mating block. A rubber sleeve is provided on the outside of the fitting and is fitted at the connection between the fitting and the mating block. A first rubber ring is provided at one end of the rubber sleeve and is fitted on the outside of the fitting. A second rubber ring is provided at the other end of the rubber sleeve and is fitted on the outside of the mating block. The mating block and the fitting are connected and fixed by a clamp.
[0006] Preferably, the clamp is composed of a first annular block and a second annular block, and the inner sides of the first annular block and the second annular block are provided with grooves. The front end of the connector is provided with a first convex ring, and the front end of the mating block is provided with a second convex ring. The first convex ring and the second convex ring are both engaged inside the grooves.
[0007] Preferably, the front end of the mating block is provided with a connecting ring, the outer wall of the connecting ring is provided with threads, the inner wall of the joint is provided with threads corresponding to the connecting ring, and the connecting ring is inserted into the interior of the joint when the mating block is connected to the joint.
[0008] Preferably, the first annular block and the second annular block are connected by a connector, and the first annular block and the second annular block can be opened and closed by the connector. A fixing block is provided on the other side of the first annular block and the second annular block. The first annular block and the second annular block are fixed by fixing bolts and fixing nuts, and the fixing bolts pass through the round holes on the surface of the fixing blocks on both sides and are connected to the fixing nuts.
[0009] Preferably, the surface of the docking block is provided with an annular groove, and the second rubber ring is engaged with the outside of the annular groove.
[0010] Preferably, the outer side of the mating block is provided with a second retaining ring, and the second retaining ring passes through the rubber sleeve to engage the second rubber ring inside the annular groove. The outer side of the joint is provided with a first retaining ring, and the first retaining ring passes through the rubber sleeve to engage the first rubber ring at the end of the joint.
[0011] Beneficial effects: Compared with the prior art, the significant features of this utility model are:
[0012] (1) By setting a rubber sleeve, after the joint and the mating block are mated, the rubber sleeve extends from the end of the joint and is placed on the end of the mating block, so that the connection between the joint and the mating block is wrapped by the rubber sleeve. The two ends of the rubber sleeve are respectively provided with a first rubber ring and a second rubber ring. The first rubber ring and the second rubber ring are respectively locked to the end of the joint and the mating block by a retaining ring, so that the rubber sleeve is fixed to the outside of the joint and the mating block. The rubber sleeve can seal the mating point, thereby preventing leakage.
[0013] (2) After the joint and the mating block are mated, the rubber sleeve is wrapped around the outside of the joint and the mating block. Then, the clamp is used to lock the joint and the mating block together. The rubber sleeve at the mating point is also clamped inside the groove by the clamp, so that the joint and the mating block are more firmly connected and the sealing is better, and it is not easy for leakage to occur.
