Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic accessories, and in particular relates to a novel hydraulic pipe joint. Background Art

[0002] Hydraulic pipe joints are commonly used in hydraulic pipe fittings and are mainly used for transitional connections of hydraulic pipes. The existing hydraulic pipe joints are very simple in design and are mostly composed of a joint body, an input end, and an output end. However, traditional hydraulic pipe joints do not have a pressure relief device, which can easily lead to safety accidents such as leakage in high-pressure hydraulic pipes.

[0003] When the hydraulic pressure in the hydraulic pipe joint body is high, the connection between the hydraulic pipe joint body and the hydraulic pipe is prone to leakage, causing internal liquid to leak out, making the hydraulic system unstable and affecting its service life.

[0004] Therefore, a new hydraulic pipe joint is needed to solve the above problems. Utility Model Content

[0007] Based on the above, the locking mechanism includes a slideway opened on the joint body, a through groove is provided between the slideway and the flow hole, a locking rod is slidably provided in the through groove, the end of the locking rod close to the flow hole is an inclined surface, a connecting rod is slidably provided in the slideway, one end of the connecting rod is connected to the locking rod, and the other end of the connecting rod is connected to a push plate that slides against the joint body, and an elastic support rod that applies elastic force to the locking rod is provided in the slideway; the side wall of the pipe joint is provided with a locking groove corresponding to the locking rod.

[0010] Based on the above, a rubber skin is provided on the pipe joint.

[0011] The utility model has substantial characteristics and progress compared with the prior art. Specifically, the utility model has the following advantages:
