Detailed Description
The present utility model will be further specifically described below by way of examples in order to make the objects, technical solutions and advantages of the present utility model more apparent.
Example 1
Referring to fig. 2-3, the quick assembly pipe joint comprises a copper joint body and a clamping sleeve 4, wherein the joint body comprises an integrally machined interface connection part 1 and a pipe inserting part 2, an oil duct is formed by penetrating the inside of the interface connection part 1, external threads matched with the interface are arranged on the outer surface of the interface connection part and are used for being fixedly connected with the interface, and external hexagons are arranged in the opposite middle parts of the joint body, so that the joint body can be conveniently screwed into the interface by using a spanner.
The pipe inserting part 2 is provided with a pipe inserting opening 3, the pipe inserting opening 3 is communicated with an oil duct in the interface connecting part 1, the inner diameter of the pipe inserting opening is matched with the outer diameter of a pipe, the clamping sleeve 4 is in threaded fit with the pipe inserting part 2, one end of the clamping sleeve 4 is opened and sleeved on the pipe inserting part 2, and the outer end face of the other end is provided with a penetrating opening matched with the outer diameter of the pipe for the pipe to pass through.
In the above-mentioned structure, the terminal surface of pipe grafting portion 2 is the conical surface, and the outer terminal surface inboard of cutting ferrule 4 is equipped with the wedge face 6 that corresponds with this conical surface for when cutting ferrule 4 was screwed up, wedge face 6 extrudeed conical surface 5, because the material of joint body is the copper that the ductility is preferred in this embodiment, consequently can make the port of pipe grafting portion 2 produce deformation to the inboard, makes the port size of pipe grafting portion 2 diminish, thereby can produce the fastening effect to the pipe. In practical application, the difference of the inclination angles of the conical surface 5 and the wedge surface 6 can be changed to make the extrusion deformation more easy, for example, the included angle between the wedge surface and the axial direction is slightly larger than the included angle between the conical surface and the axial direction.
In this embodiment, the outer surface of the ferrule 4 is also provided with an external hexagonal profile for facilitating the screwing of the wrench.
The pipe joint of this embodiment can be when leaving the factory with cutting ferrule 4 pre-installation on pipe grafting portion 2, will twist it to wedge face 6 and conical surface 5 contact but do not exert the extrusion force (manual tightening can,) at this moment, the port of pipe grafting portion 2 does not take place deformation. In specific implementation, after the interface connection part 1 is screwed on the interface of the lubrication system through a wrench, the pipe is inserted into the pipe inserting part 2, and then the clamping sleeve 4 is screwed through the wrench, so that the assembly can be completed.
Example 2
Referring to fig. 4, the difference between the present embodiment and embodiment 1 is that the present embodiment further provides a bushing core 7 in the pipe socket 3, specifically, the outer diameter of the bushing core 7 matches with the inner diameter of the pipe, the inside of the bushing core 7 is communicated with the oil passage in the interface connection portion 1, and the function of the bushing core 7 is to support the inside of the pipe, so that the fastening effect is more stable and firm after the assembly is completed.
Of course, the outer diameter at the end of the core 7 can be designed to be slightly smaller in order to facilitate insertion of the tube.
The above embodiments are provided to illustrate the technical concept and features of the present utility model and are intended to enable those skilled in the art to understand the content of the present utility model and implement the same, and are not intended to limit the scope of the present utility model.
