Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to a hydraulic system pipe joint sleeve. Background Art

[0002] The hydraulic system is a mechanism that compresses liquid and transmits pressure through pipes. The system has the advantages of high efficiency, precision and stability. Connecting pipes are a vital component of the hydraulic system. They are used to connect various parts and keep the system running stably. The connection between hydraulic pipes requires the use of joint sleeves to form a closed hydraulic circuit.

[0003] After the threaded joint on the current hydraulic hose is threadedly connected to the joint sleeve, there is no corresponding protective structure at the threaded joint part. When it is hit by a collision, it is easy to deform and leak. At the same time, the threaded joint and the joint sleeve are also prone to loosening due to factors such as vibration, resulting in leakage. For this reason, we propose a hydraulic system pipe joint sleeve. Utility Model Content

[0004] The purpose of the utility model is to provide a hydraulic system pipe joint sleeve, which has the function of protecting the hydraulic hose threaded joint to prevent the threaded joint connection from being deformed and damaged due to impact, and at the same time limits the rotation of the threaded joint to prevent loosening between the threaded joint and the joint sleeve, thereby avoiding leakage. It solves the problem that the threaded joint on the current hydraulic hose has no corresponding protective structure after being threadedly connected to the joint sleeve, and is prone to deformation and leakage when subjected to collision. At the same time, the threaded joint and the joint sleeve are also prone to loosening due to factors such as vibration, thereby causing leakage.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a hydraulic system pipe joint sleeve, comprising a joint sleeve body and a hydraulic hose, one end of the hydraulic hose is fixedly connected to a threaded joint, the outer surface of the joint sleeve body is provided with connecting threads near both ends, the outer surface of the joint sleeve body is slidably sleeved with sliding sleeves near both ends, the outer sides of the two sliding sleeves are fixed with mounting mouth limit sleeves, and the outer sides of the two limit sleeves are provided with limit sockets, the outer surfaces of the two sliding sleeves are provided with threaded holes, and locking screws are movably inserted into the threaded holes.

[0006] Preferably, the threaded joint and the joint sleeve body are fixedly connected via connecting threads.

[0007] Preferably, a horizontal cutout is provided at a middle position on the outer surface of the joint sleeve body.

[0008] Preferably, a limit ring is provided on the outer surface of the joint sleeve body near the two connection thread positions.

[0009] Preferably, an annular limiting groove is provided on the outer surface of the joint sleeve body near the two connecting thread positions, and the limiting snap ring is located inside the annular limiting groove.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] The utility model provides a hydraulic hose threaded joint to play a protective role by arranging a joint sleeve body, a connecting thread, a hydraulic hose, a threaded joint, a sliding sleeve, a threaded hole, a locking screw, a limiting sleeve and a limiting socket, so as to prevent the threaded joint connection from being deformed and damaged due to impact, and at the same time limit the rotation of the threaded joint, and prevent the threaded joint and the joint sleeve from loosening, thereby avoiding leakage. The sliding sleeves and the limiting sleeves at both ends of the joint sleeve body are slid toward the middle to expose the connecting threads at both ends of the joint sleeve body, and then the threaded joint is fixed to the two ends of the joint sleeve body through the connecting thread to complete the connection of the two hydraulic hoses, the sliding sleeve is slid to insert the threaded joint into the limiting socket, and then the locking screw is turned so that the end of the locking screw contacts the outer surface of the joint sleeve body, and the sliding sleeve and the limiting sleeve are fixed. Since the threaded joint is located inside the limiting sleeve, the threaded joint can be prevented from being deformed due to impact, and at the same time limit the rotation of the threaded joint, and loosening between the threaded joint and the joint sleeve body is avoided, thereby avoiding leakage.

[0012] The utility model provides a horizontal cutout, which makes it easy to use a wrench to clamp and fix the joint sleeve body, so as to facilitate the rotation of the threaded joint, so that the threaded joint is fixed on the joint sleeve body.

[0013] The utility model provides an annular limiting groove and a limiting clamping ring, thereby limiting the sliding sleeve on the joint sleeve body, so as to prevent the sliding sleeve from slipping off the joint sleeve body. BRIEF DESCRIPTION OF THE DRAWINGS
