[0024] like Figures 1-5 As shown, a steel-lined PTFE pipe includes a first steel-lined pipe body 1, a first flange 3 is installed at the end of the first steel-lined pipe body 1, the first flange 3 is fitted with a second flange 4, the second flange 4 is installed on the second steel-lined pipe body 2, and an installation mechanism 5 is provided on the first flange 3 and the second flange 4, and the first flange 3 and the second flange 4 are fixedly connected by the installation mechanism 5.

[0025] The mounting mechanism 5 includes a moving part and a locking part. The moving part is disposed on the second flange 4, and the locking part is disposed on the first flange 3. The moving part includes a movable cavity 51 opened in the second flange 4, a slide groove 52 opened in the movable cavity 51, a slider 53 slidably connected to the slide groove 52, a movable plate 55 connected to the slider 53 and inserted into the movable cavity 51, a return spring 54 disposed in the slide groove 52, a cross plate 56 connected to the outer wall of the movable plate 55, and a locking block 57 installed on the outer wall of the cross plate 56. The locking part includes a locking groove 58 uniformly opened in a circumferential manner in the first flange 3.

[0026] When the staff needs to fix and install the first steel lining pipe body 1 and the second steel lining pipe body 2, the horizontal plate 56 is pulled outwards in advance, so that the horizontal plate 56 drives the movable plate 55 to slide outwards, the movable plate 55 slides outwards in the sliding groove 52 through the sliding block 53, the pulling of the reset spring 54 generates deformation in the sliding process, at this time, the movable plate 55 drives the horizontal plate 56 and the clamping block 57 to move to the outermost end, at this time, the staff only needs to make the first flange plate 3 and the second flange plate 4 adhere to each other, so that the movable cavity 51 and the clamping groove 58 correspond, at this time, the loosened horizontal plate 56 is pulled, the restoring force of the elasticity of the reset spring 54 drives the movable plate 55 to restore, and finally the movable plate 55 drives the horizontal plate 56 to adhere to the outer wall of the first flange plate 3 and the second flange plate 4, so that the clamping block 57 is clamped with the clamping groove 58 to form fixation;

[0027] It is worth noting that the movable cavity 51 is uniformly provided with eight groups around the second flange plate 4, and the uniform arrangement of the eight groups of movable cavities 51 can ensure that the force distribution around the entire second flange plate 4 is uniform, which is helpful to prevent distortion or deformation when the pipeline is connected, and two groups of sliding grooves 52 are symmetrically arranged in each movable cavity 51, and the symmetrical sliding grooves 52 are helpful to keep the balance of the structure and ensure uniform force transmission during connection; one end of the reset spring 54 is connected with the inner wall of the sliding groove 52, and the other end of the reset spring 54 is connected with the outer wall of the sliding block 53, and the design of the reset spring 54 enables the movable plate 55 to automatically reset after operation, reduces the manual operation steps, and improves the installation efficiency;

[0028] The clamping groove 58 is equal in shape to the clamping block 57, and the equal shape of the clamping groove 58 and the clamping block 57 ensures accurate matching, thereby providing a firm mechanical connection, and the equal shape reduces the possibility of misalignment during installation, thereby ensuring the correctness and consistency of the connection.
