Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of pipe joints, in particular to a quick-connect pipe joint. Background Art
[0002] Pipe fittings are connecting tools between pipes, and are detachable connection points between components and pipes. They play an indispensable and important role in pipe fittings and are the main components of hydraulic pipes. Pipe fittings are used for linear connections such as instruments, and the connection forms include socket welding or threaded connection. They are mainly used for small-diameter low-pressure pipelines, for parts that need to be frequently assembled and disassembled, or for the final adjustment of pipelines using threaded pipe fittings. When the pipe fitting is connected to the pipeline, in order to prevent the separation of the pipeline and the pipe fitting, the pipe on the pipe fitting is generally clamped by a pipe sleeve. The pipe sleeve needs to be put on the pipe on the pipe fitting with a large force, which is time-consuming and labor-intensive. At the same time, it is not convenient to remove the pipe sleeve when replacing the pipe fitting and the pipeline. Utility Model Content

[0006] At the middle position of the other end of the first pipe clamp, a third connecting block is fixedly arranged. A first threaded hole is opened at the middle position of the third connecting block. At the middle position of the other end of the second pipe clamp, a fourth connecting block is fixedly arranged. A second threaded hole is opened at the middle position of the fourth connecting block. A bolt is arranged through the first threaded hole and the second threaded hole, and a nut is tightly sleeved on the bolt. Through the bolt and the nut, the first pipe clamp and the second pipe clamp are firmly and reliably connected together, so as to ensure that the pipeline is tightly clamped on the joint pipe.
[0007] Preferably, a plurality of layers of snap rings are uniformly and fixedly arranged on the outer wall of the joint pipe, which increases the friction force between the pipeline and the joint pipe and prevents the pipeline from disengaging from the joint pipe.
[0008] Preferably, bevels are opened at both ends of the joint pipe to facilitate the insertion of the pipeline onto the joint pipe.
[0009] Preferably, the outer diameter of the limiting block is larger than the apertures of the first through hole and the second through hole, preventing the first connecting block and the second connecting block from disengaging from the shaft rod.
[0010] Preferably, the longitudinal section of the block body is fan-shaped, which increases the contact surface between the block body and the pipeline and ensures the tight connection between the block body and the pipeline.
[0011] The beneficial effects of the present utility model are as follows: The block body is sleeved on the screw rod of the joint pipe, and the position of the block body can be adjusted according to the thickness of the pipeline. The first pipe clamp and the second pipe clamp and the joint pipe form an integral structure, which is convenient to carry. It can not only facilitate and quickly connect the joint pipe and the pipeline, but also save time and effort and is convenient for replacing the pipe joint or the pipeline.

[0018] In order to more clearly understand the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.
[0019] As Figures 1-5A quick-connect pipe joint shown in the figure includes a joint pipe 1. A pipeline is sleeved on the joint pipe 1. A screw rod 2 is vertically and fixedly arranged at the middle position on the outer wall of the joint pipe 1. A block 3 is sleeved on the screw rod 2, and the block 3 moves along the screw rod 2. A first locking nut 4 and a second locking nut 5 are tightly sleeved on the screw rod 2. Move the block 3 to make the block 3 tightly abut against the pipeline on the joint pipe 1, and then rotate the first locking nut 4 and the second locking nut 5 to limit the position of the block 3, ensuring the extrusion of the block 3 on the pipeline. The longitudinal section of the block 3 is a sector ring, which increases the contact surface between the block 3 and the pipeline and ensures the tight connection between the block 3 and the pipeline. Symmetrically fixed at the middle positions at both ends of the block 3 are shaft rods 6, which are arranged parallel to the joint pipe 1. Fixed at the end of the shaft rod 6 away from the block 3 is a limit block 7, which limits the positions of the first connecting block 10 and the second connecting block 12. The outer diameter of the limit block 7 is larger than the apertures of the first through hole 11 and the second through hole 13, preventing the first connecting block 10 and the second connecting block 12 from detaching from the shaft rod 6. Symmetrically arranged on both sides of the joint pipe 1 are a first pipe clamp 8 and a second pipe clamp 9. The pipeline on the joint pipe 1 is clamped by the first pipe clamp 8 and the second pipe clamp 9 to ensure the stable and reliable connection between the pipeline and the joint pipe 1. At one end of the first pipe clamp 8, a first connecting block 10 is fixedly arranged in parallel. A first through hole 11 is opened at the middle position of the first connecting block 10. At one end of the second pipe clamp 9, a second connecting block 12 is fixedly arranged in parallel. A second through hole 13 is opened at the middle position of the second connecting block 12. The shaft rod 6 passes through the first through hole 11 and the second through hole 13, which not only ensures the reliable connection between the first pipe clamp 8 and the second pipe clamp 9 and the shaft rod 6 and the stable positions of the first pipe clamp 8 and the second pipe clamp 9, but also enables the first pipe clamp 8 and the second pipe clamp 9 to rotate around the shaft rod 6. Fixed at the middle position of the other end of the first pipe clamp 8 is a third connecting block 14. A first threaded hole 15 is opened at the middle position of the third connecting block 14. Fixed at the middle position of the other end of the second pipe clamp 9 is a fourth connecting block 16. A second threaded hole 17 is opened at the middle position of the fourth connecting block 16. A bolt 18 is arranged through the first threaded hole 15 and the second threaded hole 17. A nut 19 is tightly sleeved on the bolt 18. Through the bolt 18 and the nut 19, the first pipe clamp 8 and the second pipe clamp 9 are firmly and reliably connected together, thereby ensuring that the pipeline is tightly clamped on the joint pipe 1.
[0020] A plurality of layers of snap rings 20 are uniformly and fixedly arranged on the outer wall of the joint pipe 1 to increase the friction between the pipeline and the joint pipe 1 and prevent the pipeline from detaching from the joint pipe 1. Grooves 21 are opened at both ends of the joint pipe 1 to facilitate the insertion of the pipeline onto the joint pipe 1.
[0021] The above are only the preferred embodiments of the present utility model. Therefore, all equivalent changes or modifications made according to the structures, features and principles described in the scope of the patent application of the present utility model are included in the scope of the patent application of the present utility model.
