Description

Technical Field

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

[0002] A hydraulic pipe joint is a component used to connect high-pressure oil pipes in a hydraulic system. There are many types of hydraulic pipe joints, which can generally be divided into sleeve joints, welded joints, flared pipe joints, etc. Compared with common pipe joints, hydraulic pipe joints can withstand greater pressure, thus playing a good connection role in high-pressure oil pipes.

[0003] When using the current hydraulic pipe joint, the joint flange is welded to the hydraulic pipe using a hot melt gun. During use, the external pressure causes the hydraulic pipe to vibrate, which will reduce the stability of the connection between the joint flange and the hydraulic pipe, easily leading to cracks in the weld, thereby damaging the hydraulic pipe.

[0004] Therefore, in view of the above problems, it is necessary for the applicant to design a sealed hydraulic pipe joint to solve the problem. Utility Model Content

[0008] Through the above structural design, during use, after the hydraulic pipe is welded to the first connecting flange or the second connecting flange, the extension plate is rotated so that the extension plate is located above the hydraulic pipe, and then the pressing plate is rotated to match the outer surface of the hydraulic pipe. At the same time, the threaded rod is rotated. The rotation of the threaded rod will drive the sliding sleeve to descend, and the descending sliding sleeve will drive the pressing plate to be close to the hydraulic pipe, which will facilitate improving the stability of the hydraulic pipe and the first connecting flange or the second connecting flange, thereby protecting the hydraulic pipe and increasing the service life of the hydraulic pipe.

[0009] Furthermore, a rotating handle for saving effort is fixedly provided at one end of the threaded rod away from the sliding sleeve, and the horizontal cross-section of the rotating handle is an equilateral hexagon.

[0010] With the above structural design, the threaded rod can be rotated effortlessly by utilizing the hexagonal rotating handle.

[0011] Furthermore, a movable screw is movably provided on one side of the movable plate, and one end of the movable screw is threadedly connected to the first connecting flange or the second connecting flange.

[0012] With the above structural design, rotating the movable screw will facilitate stabilizing the movable plate.

[0013] Furthermore, a screw head is integrally fixedly provided at one end of the movable screw away from the first connecting flange or the second connecting flange, and a tool groove is provided on an outer surface of one side of the screw head for saving effort.

[0014] Through the above structural design, when in use, the tool is inserted into the tool slot and rotated, which will facilitate the rotation of the screw head. The rotation of the screw head will facilitate the rotation of the movable screw, thereby facilitating the stable connection between the movable plate and the first connecting flange or the second connecting flange.

[0015] Furthermore, the sealing gasket is located inside the first hole and the second hole, and the inner diameter of the sealing gasket is the same as the inner diameter of the first connecting flange and the second connecting flange.

[0016] Through the above structural design, the sealing gasket is used to improve the sealing degree of the connection between the first connecting flange, the second connecting flange and the hydraulic pipe, thereby preventing liquid leakage in the hydraulic pipe.

[0017] Compared with the prior art, the beneficial effects of the present invention are: the sealed hydraulic pipe joint is convenient for connecting the hydraulic pipe, the connection is stable, and the service life of the hydraulic pipe is increased. The specific contents are as follows:

[0018] During use, after the hydraulic pipe is welded to the first connecting flange or the second connecting flange, the movable plate is rotated, and the movable plate drives the extension plate to rotate. When the extension plate is located above the hydraulic pipe, the tool is inserted into the tool slot and rotated, which will facilitate the rotation of the screw head. The rotation of the screw head will facilitate the rotation of the movable screw, thereby facilitating the firm connection between the movable plate and the first connecting flange or the second connecting flange. Then, the pressing plate is rotated to match the outer surface of the hydraulic pipe, and the threaded rod is rotated at the same time. The rotation of the threaded rod will drive the sliding sleeve to descend, and the descending sliding sleeve will drive the pressing plate to close to the hydraulic pipe, which will facilitate the improvement of the stability of the hydraulic pipe and the first connecting flange or the second connecting flange, thereby protecting the hydraulic pipe and increasing the service life of the hydraulic pipe.
