[0022] Example 1

[0023] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0024] like Figure 1-2 As shown, the utility model provides a quick-connect device for coating a functional layer on a plastic pipe, which is characterized by comprising a fixing part, a quick-connect device body 3, a connecting part, a tube-pulling and pressing component 5, and a connecting pipe. The middle part of the quick-connect device body 3 is connected to the connecting pipe through the connecting part and the tube-pulling and pressing component 5, and the left and right ends of the quick-connect device body 3 are respectively connected to the plastic pipe 1 through the fixing part.

[0025] The fixing part is the locking screw 2.

[0026] The connecting part is the inverted buckle steel sheet 4.

[0027] The connecting pipe is the high-temperature resistant connecting pipe 6.

[0028] Embodiment 2

[0029] A quick pipe connection device for coating a functional layer on a plastic pipe includes a fixing part, a main body of the quick connection device, a connecting part, a pipe pulling pressing part, and a connecting pipe.

[0030] There are two main bodies of the quick connection device, which are connected to each other through a connecting part, a pipe pulling pressing part, and a connecting pipe. Threaded holes are provided at the other ends of these two main bodies of the quick connection device, and they can be tightly connected to the plastic pipe through threads. This design makes the connection process more firm and ensures that there will be no loosening during use.

[0031] A pipe pulling pressing part is installed inside the main body of the quick connection device. A connecting part is installed at the front end of the pipe pulling pressing part. Although the connecting part and the pipe pulling pressing part are in contact, they are not directly connected. The upper end of the connecting part is installed inside the main body of the quick connection device.

[0032] The fixing part is a locking screw, which plays a role in fixing the main body of the quick connection device and the plastic pipe, ensuring the stability of the entire connection process.

[0033] The connecting part is an inverted buckle steel sheet. This design can effectively prevent the connection from falling off and improve the reliability of the connection.

[0034] The connecting pipe is a high-temperature resistant connecting pipe, which can withstand relatively high temperatures, is suitable for connecting plastic pipes in various high-temperature environments, and has a certain pressing recovery elasticity. It can withstand a certain amount of external force extrusion deformation and has a locking connection function in cooperation with the external force extrusion deformation of the connecting part.

[0035] The connecting part includes a connecting portion and a fixing portion, which are connected at an obtuse angle to ensure the stability of the connection by restricting relative displacement.

[0036] The pipe pulling pressing part is composed of a push plate and a moving part. The push plate and the moving part are connected through a connecting part. The top end of the moving part is a pointed structure, which can more easily insert under the connecting part. The contact between the top end of the moving part and the connecting part enables the connecting pipe to return to its original state after losing the external force extrusion of the connecting part, achieving the effect of disconnecting the high-temperature resistant connecting pipe from the main body of the quick connection device, making the pipe pulling process smoother and reducing the resistance during pipe pulling.

[0037] Generally speaking, this rapid pipe connection device for coating functional layers on plastic pipes improves the connection speed and stability through its unique structure and design, and is applicable to the connection section in the continuous production process of plastic pipes.

[0038] Embodiment 3

[0039] When two plastic pipes 1 need to be coated with functional layers, at present, most of them first coat the previous plastic pipe 1 on the coating equipment, and then stop the machine to prepare for the coating of the next section of plastic pipe 1, where the two sections of plastic pipes 1 are separated.

[0040] When the present utility model is in use: the high-temperature resistant connecting pipe 6 can be pulled out from the quick connection device main body 3 by pressing the pipe pulling pressing component 5. After being pulled out, the present utility model becomes a component with a high-temperature resistant connecting pipe 6, a pipe pulling pressing component 5, an inverted buckle steel sheet 4 and a half part of the quick connection device main body 3 on one side, while the other side only has a pipe pulling pressing component 5, an inverted buckle steel sheet 4 and a half part of the quick connection device main body 3.

[0041] Then, the part of the component with the high-temperature resistant connecting pipe 6 is connected to the previous plastic pipe 1 to be coated through the locking screw 2, and the other part of the component without the high-temperature resistant connecting pipe 6 is connected to the next plastic pipe 1 to be coated through another locking screw 2. After both parts are connected, the high-temperature resistant connecting pipe 6 is directly inserted into the other part of the component without the high-temperature resistant connecting pipe 6 again, and is clamped by the inverted buckle steel sheet 4, so that the two discontinuous plastic pipes 1 can be connected into a whole to realize the coating operation without stopping the machine.

[0042] When the two sections of plastic pipes 1 need to be disassembled, the operation can be carried out by pressing the pipe pulling pressing component 5 to achieve rapid pulling out, so as to quickly disassemble the two sections of plastic pipes 1.

[0043] The locking screw 2 is completely rotated into the quick connection device main body 3, and the pre-drilled plastic pipe 1 is installed on the quick connection device main body 3. The locking screw 2 is screwed out to connect the pipe 1 with the quick connection device main body 3.

[0044] The inverted buckle steel sheet 4 is a steel sheet with a non-return function. When the connecting pipe is inserted, the inverted buckle steel sheet 4 is in a one-way locking state. After the high-temperature resistant connecting pipe 6 is inserted to the bottom, the inverted buckle of the inverted buckle steel sheet 4 has a locking effect on the high-temperature resistant connecting pipe 6. Press the pipe pulling pressing component 5 to enter, expand the inverted buckle locking range of the inverted buckle steel sheet 4, and the high-temperature resistant connecting pipe 6 can be pulled out.
