Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1 to Figure 7 As shown, this embodiment proposes a pipe joint that is easy to install, including a pipe connector 1, a removable support ring 4 is installed on the inner wall of the pipe connector 1, and a filter screen 5 is fixedly connected to the inner wall of the support ring 4. The filter screen 5 can filter impurities inside the medium transported by the pipeline. When the filter screen 5 is damaged, the support ring 4 can be disassembled to complete the replacement of the support ring 4.

[0029] A fixing mechanism 2 is arranged on the outside of the pipe connector 1, and the fixing mechanism 2 includes two medium conveying pipes 201, four sliding rods 202 and four arc blocks 204 which are slidably connected to the pipe connector 1. The arc blocks 204 are slidably connected to the medium conveying pipes 201, and one end of each sliding rod 202 away from the arc block 204 is fixedly connected to a connecting plate 203, and the sliding rod 202 is fixedly connected to the arc block 204.

[0030] The outer diameter of the medium conveying pipeline 201 is the same as the inner diameter of the pipeline connector 1. The medium conveying pipeline 201, the slide rod 202 and the arc block 204 can all slide in the inner wall of the pipeline connector 1. Pulling the connecting plate 203 can drive the slide rod 202 to move, and the slide rod 202 drives the arc block 204 to move.

[0031] Two sealing gaskets 6 are arranged inside the pipe connector 1. Both sealing gaskets 6 are in contact with the support ring 4. The two sealing gaskets 6 are in contact with two medium conveying pipes 201 respectively. The sealing gaskets 6 can improve the sealing performance of the connection between the pipe and the pipe joint to avoid leakage of the medium conveyed inside the pipe.

[0032] Four guide blocks 7 are fixedly connected to the inner wall of the pipe connector 1, and two slide grooves 8 are provided on the outer surfaces of the two medium conveying pipes 201. The guide blocks 7 are adapted to the slide grooves 8. The movement of the pipe is guided by the guide blocks 7 and the slide grooves 8, making it more stable during the movement.

[0033] Two symmetrical guide rods 3 are fixedly connected to the side surfaces of the two arc blocks 204 that are away from each other. Each guide rod 3 is slidably connected to the pipe connector 1. The guide rod 3 is fixedly connected to the connecting plate 203. The movement of the arc block 204 can be guided by the guide rod 3, making it more stable during the movement.

[0034] A return spring 205 is sleeved on the outer surface of each slide rod 202 . Each return spring 205 is fixedly connected to the pipe connector 1 . The return spring 205 is fixedly connected to the arc block 204 .

[0035] After the arc block 204 moves, it will compress the return spring 205 to make it produce elastic deformation. When the arc block 204 is not affected by external force, the return spring 205 can be driven to return to the initial position under the return action of the return spring 205.

[0036] Example 2

[0037] like Figure 1 to Figure 7 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that a support plate 9 and two bidirectional threaded rods 11 are arranged below the pipe connector 1, and four fixing blocks 10 are fixedly connected to the upper surface of the support plate 9, and the fixing blocks 10 are rotatably connected to the bidirectional threaded rods 11. The outer surfaces of the two bidirectional threaded rods 11 are threadedly connected to two arc-shaped clamping plates 12 that are slidably connected to the support plate 9.

[0038] The outer surfaces of the two bidirectional threaded rods 11 are fixedly connected with handles 13, and the bidirectional threaded rods 11 can be easily rotated through the handles 13, and the comfort during rotation is improved.

[0039] In this embodiment, by rotating the bidirectional threaded rod 11, the two arc-shaped clamping plates 12 thereon can be driven to slide along the upper surface of the support plate 9, and the two arc-shaped clamping plates 12 can approach and move away from each other, thereby achieving limited support for pipe joints of different diameters, thereby reducing the possibility of breakage at the pipe joints and ensuring the stability of the pipe joint connections.

[0040] In addition, the present embodiment also proposes that two mounting blocks 14 are fixedly connected to one side and the other side of the support plate 9, and a straight groove is opened on the upper surface of each mounting block 14. The mounting block 14 can be used to conveniently install and fix the support plate 9, and the installation position can be fine-tuned, thereby achieving stable support for the connection of the pipe joint.

[0041] Working principle: When using the easy-to-install pipe joint to connect two pipes, the staff holds the pipe connector 1 and the medium delivery pipe 201 with both hands respectively, and gradually slides the medium delivery pipe 201 into the interior of the pipe connector 1. When the medium delivery pipe 201 contacts the arc surface of the arc block 204 and continues to move, the arc block 204 will be squeezed, so that the arc block 204 gradually slides into the reserved groove of the pipe connector 1. After the arc block 204 moves, it will drive the slide bar 202 to slide in the inner wall of the pipe connector 1, and the slide bar 202 drives the connecting plate 203 to move. At the same time, the arc block 204 will compress the return spring 205 to cause it to produce elastic deformation until the medium delivery pipe 201 is in contact with the arc surface of the arc block 204. The pipe 201 slides into place. At this time, under the resetting action of the resetting spring 205, the arc block 204 will be driven to slide into the reserved groove provided on the medium conveying pipe 201, so as to realize the limit fixation of the medium conveying pipe 201 and complete the connection between the pipe connector 1 and the medium conveying pipe 201. Referring to the above method, the other medium conveying pipe 201 can be slid into the pipe connector 1. When the utility model uses a pipe connector to connect two pipes, it only needs to gradually slide the two pipes into the pipe connector, so that the fixing component provided on the pipe connector can be stuck in the reserved groove on the pipe, and the installation of the pipe is completed. The whole installation process is simple and fast, and the operation is simple, which is worthy of promotion.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
