Abstract

The invention relates to the technical field of hydraulic manifold blocks, and particularly discloses a hydraulic manifold block abutting joint structure, which includes an abutting pipe, wherein an annular layer is fitted with the surface of the abutting pipe; oval spheres are uniformly inlaid on the surface of the annular layer; an oval cavity is formed inside each oval sphere; a shape-changingcavity is formed between every two oval spheres inlaid on the surface of the annular layer. According to the invention, the oval spheres inlaid on the surface of the annular layer cooperate with the oval cavities formed inside the oval spheres and the shape-changing cavities formed inside the annular layer, the oval spheres have the shape-changing effect, so that the threads formed on the inner wall of an oil port are fulled with the oval spheres, that is, the device is tightly fitted with the oil port, and then is matched with the threads formed on the inner wall of the abutting pipe, therefore, the effect that the manifold block can be used through the abutting joint structure after the threads on the inner wall of the oil pipe slip, is achieved.

Description

technical field [0001] The invention relates to the technical field of hydraulic oil circuit blocks, in particular to a butt joint structure of hydraulic oil circuit blocks. Background technique [0002] The oil circuit block is a collection of dispersed hydraulic oil circuits. The oil block is simply a block that controls the work of hydraulic oil. Usually made of metal. For each hydraulic system, the oil circuit block needs to be designed individually according to the hydraulic schematic diagram. Its advantage is to simplify the installation, overhaul, replacement and later maintenance of the hydraulic system. [0003] The existing hydraulic oil block generally connects the valve and the oil port through a mounting plate and corresponding pipelines. However, when the existing valve and the oil port are connected, it may be impossible to connect the valve with the oil block due to the threaded wire inside the oil port, thus making the oil block unusable.
