DETAILED DESCRIPTION

[0015] like Figure 1-4As shown: a CPVC power pipe expansion device, including a fixing seat 1, the left and right ends of the front side wall of the fixing seat 1 are respectively provided with circular grooves 2; the front side of the fixing seat 1 is provided with two fixing cylinders 3, the rear ends of the two fixing cylinders 3 are respectively in the circular grooves 2, the rear ends of the fixing cylinders 3 are clearance-matched with the inner wall of the circular groove 2, the front end outer wall of the fixing cylinder 3 is provided with four mounting holes 4, the four mounting holes 4 are evenly distributed on the front end outer wall of the fixing cylinder 3, the front end inner wall of the fixing cylinder 3 is threadedly connected with a limiting cap 5, the interior of the fixing cylinder 3 is provided with a push rod 6, the rear end of the push rod 6 passes through the circular groove 2 and is slidably matched with the circular groove 2, a synchronization plate 13 is fixedly connected between the rear ends of the two push rods 6, the middle part of the rear side wall of the fixing seat 1 is fixedly connected to one end of the cylinder barrel of the cylinder 12, The cylinder 12 is between the synchronous plate 13 and the fixed seat 1, and the piston rod of the cylinder 12 is fixedly connected to the center of the synchronous plate 13. An expansion plate 10 is provided on the inner side of the mounting hole 4. The rear ends of the left and right side walls of the expansion plate 10 are rotatably connected to the rear end of the inner wall of the mounting hole 4. The front end of the inner wall of the expansion plate 10 is fixedly connected to two connecting frames 2 11. The outer wall of the push rod 6 is fixedly connected to a fixed block 7. The outer wall of the fixed block 7 is fixedly connected to two connecting frames 1 8 at four positions of the upper, lower, left and right. A connecting rod 9 is provided between the two connecting frames 1 8 and the adjacent upper connecting frame 2 11. The two ends of the connecting rod 9 are respectively between the two connecting frames 1 8 and between the two connecting frames 2 11. The two ends of the connecting rod 9 are respectively rotatably connected to the two connecting frames 1 8 and the two connecting frames 2 11.

[0016] Two support rings 14 are slidably sleeved on the outer wall of the push rod 6 , and the two support rings 14 are fixedly connected to the front and rear ends of the inner wall of the fixed tube 3 respectively.

[0017] The support ring 14 can assist in supporting the push rod 6 and ensure the stability of the push rod 6 in moving forward and backward.

[0018] The two CPVC power pipes are respectively sleeved on the outside of the two fixed tubes 3 of the expansion device. At this time, the expansion plate 10 is in a contracted state, and the connecting rod 9 is connected between the connecting frame 1 8 and the connecting frame 2 11, but the expansion plate 10 is not fully expanded.

[0019] When expansion is required, the cylinder 12 is started, and the piston rod of the cylinder 12 contracts to push the synchronous plate 13. The synchronous plate 13 is fixedly connected to the rear ends of the two push rods 6, so the push rods 6 will also move forward synchronously. As the push rods 6 move forward, the fixed blocks 7 fixed on their outer walls will also move accordingly. The connecting frame 18 on the fixed block 7 is connected to the connecting frame 2 11 on the expansion plate 10 through the connecting rod 9. Since the two ends of the connecting rod 9 are rotatably connected to the connecting frame 18 and the connecting frame 2 11 respectively, when the connecting frame 18 moves forward, the connecting rod 9 will push the connecting frame 2 11 to make the expansion plate 10 rotate outward, thereby realizing the expansion of one end of the expansion plate 10.

[0020] As the push rod 6 continues to move forward, the expansion plate 10 continues to expand outward until a predetermined expansion size is reached. At this time, the expansion work of the two CPVC power pipes is completed at the same time.

[0021] When resetting is required, the piston rod of the cylinder 12 retracts backward, driving the push rod 6 and the fixed block 7 to move backward. Due to the action of the connecting rod 9, the expansion plate 10 rotates inward and gradually returns to the initial contracted state. The utility model only protects the mechanical part, and the functions realized by the software control part are not within the protection scope of the utility model.
