Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic hoses, in particular to a hydraulic hose connecting joint. Background Art

[0002] Hydraulic hoses are flexible pipes used to transport hydraulic oil (or other hydraulic fluids) within hydraulic systems. Because hydraulic systems typically operate at high pressures, hydraulic hoses must possess excellent pressure resistance. This capability is determined by the materials and structural design of the inner and outer layers. Hydraulic hoses must be used in a variety of complex installation environments and must be able to bend and twist to accommodate equipment layouts. Good flexibility and a small bend radius facilitate installation and use, minimizing space requirements.

[0003] When connecting hydraulic hoses, a connector is required. Chinese utility model patent publication number CN214618373U discloses a hydraulic hose connector, comprising a first connector, a connector threadedly connected to the top of the connector, an inner tube slidably connected to the interior of the connector, and a second connector slidably connected to the other side of the inner tube. In this utility model, a screw is rotated to cause the screw to begin to rotate, driving a slider to begin horizontally translating left and right within the connector. The slider then drives the connecting block to perform translational movement near a groove within the connector's inner column. This utility model can also be disassembled and inspected in reverse for troubleshooting. By rotating the second connector, the connector is disengaged from the first connector, and the second connector is pulled horizontally and translated left and right, driving the inner tube to begin sliding within the first and second connectors. This mechanism effectively solves the problem of insufficient distance between the hoses while also achieving better pressure relief and easing.

[0004] However, during use, the utility model uses a large number of threaded connections, which makes it inconvenient to disassemble and assemble the entire device. At the same time, when the joints are rubbed by the outside world, they may fall off, which cannot meet production needs. Therefore, a hydraulic hose connection joint is proposed to solve the above problems. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a hydraulic hose connection joint, which has the advantage of easy disassembly and assembly of the device, and solves the problem that the entire device may be inconvenient to disassemble and assemble due to the use of a large number of threaded connections. At the same time, when the joint is rubbed by the outside world, it may fall off, which cannot meet production needs.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: a hydraulic hose connection joint, comprising a main butt joint and a butt joint pipe provided at the bottom of the main butt joint, wherein the butt joint pipe is provided with a quick-release butt joint structure capable of butt jointing and fixing with the main butt joint;

[0007] The quick-release docking structure includes an elastic sleeve slidably connected to the outer surface of the docking pipe, the bottom of the main docking joint is fixedly connected to an insertion head extending into the interior of the docking pipe, the elastic sleeve is fixedly connected to a side close to the docking pipe with an extrusion block, the outer surface of the docking pipe is fixedly connected to a limit block capable of limiting the elastic sleeve, a reset spring is fixedly connected between the limit block and the extrusion block, and the interior of the docking pipe is slidably connected to a positioning steel ball extending into the interior of the insertion head.

[0008] Furthermore, a through hole is provided inside the docking pipe for the movement of a positioning steel ball, and a positioning groove is provided on the outer surface of the insertion head to match the positioning steel ball.

[0009] Furthermore, the outer wall of the limit block fits with the inner wall of the elastic sleeve, the return spring is slidably connected to the outer surface of the docking pipe, and a limit ring capable of limiting the insertion head is fixedly connected to the inner wall of the docking pipe.

[0010] Furthermore, the outer surface of the main joint is slidably connected to a threaded sleeve extending to the outer surface of the elastic sliding sleeve, and the threaded sleeve and the elastic sliding sleeve are connected in a threaded manner.

[0011] Furthermore, a first hose is provided on the side of the main joint away from the insertion head, and the bottom of the first hose is fixedly connected to an external threaded connector extending into the interior of the main joint, and the connection between the external threaded connector and the main joint is a threaded connection.

[0012] Furthermore, a rubber sealing ring capable of positioning the external threaded connector is fixedly connected to the inner wall of the main joint, and a sealing gasket is fixedly connected to the side of the external threaded connector close to the rubber sealing ring.

[0013] Furthermore, a second hose is fixedly provided on one end of the docking pipe away from the main docking joint, and a connecting sleeve is installed between the docking pipe and the second hose.

[0014] Compared with the prior art, the present invention provides a hydraulic hose connection joint with the following features:

[0015] Beneficial effects:

[0016] 1. The hydraulic hose connection joint is provided with a reset spring and a limit block, and then an extrusion block is provided, so that the elastic sleeve can be elastically displaced on the outer surface of the docking pipe. Then, a positioning steel ball is provided. When the elastic sleeve moves downward, the positioning steel ball can slide slightly left and right. At this time, the insertion head is inserted into the docking pipe, and the insertion head will squeeze the positioning steel ball. When the insertion head is fully inserted, the elastic sleeve moves upward due to the action of the reset spring. At this time, the extrusion block squeezes the positioning steel ball, thereby achieving the effect of fixing the insertion head and facilitating disassembly and assembly by the staff.

[0017] 2. The hydraulic hose connection joint facilitates the positioning of the insertion head by providing a limit ring, so that the positioning groove on the insertion head can directly match the positioning steel ball and achieve a sealing effect. The elastic sleeve and the main joint can be fixed for a second time by providing a threaded sleeve, thereby improving the anti-falling performance and solving the problem that the entire device may be inconvenient to disassemble and assemble due to the use of a large number of threaded connections. At the same time, when the joint is rubbed by the outside world, it may fall off, which cannot meet the production needs. BRIEF DESCRIPTION OF THE DRAWINGS
