Description

Technical Field

[0001] This utility model relates to the field of hydraulic pipe connection technology, specifically a hydraulic pipe connector with an adjustment structure. Background Technology

[0002] Hydraulic pipe fittings are parts that connect pipelines in a hydraulic system or mount pipelines onto hydraulic components. They are a general term for connectors that can be installed and removed in a fluid passage. With the development of the machinery industry and the improvement of various technical indicators, the requirements for hydraulic pipe fittings are becoming increasingly stringent. Hydraulic pipe fittings can be further divided into hydraulic hoses, high-pressure ball valves, quick couplings, compression fittings, welded fittings, high-pressure hoses, transition fittings, tee fittings, non-standard fittings, flared fittings, right-angle fittings, rotary fittings, quick couplings, stainless steel fittings, and copper fittings.

[0003] Existing hydraulic hose fittings are one-piece designs. When connecting hydraulic hoses, the end face of the hydraulic hose needs to be in full contact with the fitting before the connection is secured by threads. However, in practical use, when the distance between two hydraulic hoses is too large, the fitting cannot be directly connected, requiring multiple fittings to be used with connecting conduits, thus increasing the connection cost. Therefore, this invention proposes a hydraulic hose connector with an adjustment structure to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a hydraulic pipe connector with an adjustment structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic pipe connector with an adjustment structure, comprising: a connecting pipe, both ends of which are connected to threaded seats through adjustment components, and a sealing ring is fixedly installed inside the threaded seats;

[0006] The adjusting components include a fixed plate, a movable sleeve, and an extension cylinder. The fixed plate consists of several pieces that are evenly fixed on the outer wall of the connecting pipe. The movable sleeve is slidably fitted onto the outer wall of the connecting pipe and fixed by bolts. A connecting sleeve is fixedly installed at one end of the movable sleeve, and a sealing ring is fixedly installed at the inner end of the connecting sleeve.

[0007] One end of the extension tube is inserted into the connecting sleeve and fixed by the adjusting bolt, and the threaded seat and the other end of the extension tube are fixedly connected.

[0008] Preferably, a plurality of limiting holes are evenly provided on the outer walls of both ends of the connecting pipe.

[0009] Preferably, a threaded sleeve is fixedly installed on the outer wall of the movable sleeve, and the inner port of the threaded sleeve is connected to the inner end of the movable sleeve.

[0010] Preferably, the outer wall of the bolt and the inner wall of the threaded sleeve are threaded together, and the lower end of the bolt passes through the threaded sleeve and is inserted into the limiting hole.

[0011] Preferably, several fixing plates are uniformly fixedly installed on the outer wall of the extension tube, and one end of the adjusting bolt passes through the fixing plate and the fixing plate in sequence and is threaded with a nut.

[0012] Preferably, a slope is provided on the inner side of one end of the extension tube.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By adjusting and fixing the position of the movable sleeve on the connecting pipe according to the distance between the two hydraulic pipes to be connected, one end of the adjusting bolt passes through the through holes on the first and second fixing plates in sequence and is threaded with a nut. By tightening the nut, one end of the extension cylinder is driven to move towards the inner end of the connecting sleeve, and is tightly pressed against the outer wall of the connecting pipe by the ramp and the sealing ring, thus sealing the extension cylinder and the connecting pipe. This allows the position of the threaded seat to be adjusted to connect two hydraulic pipes at different distances. The operation is simple and reduces costs. Attached Figure Description
