[0022] Example

[0023] Please see Figures 1-4This utility model provides a technical solution: a pipe installation and fixing device with adjustable inner diameter, including a support structure 100 and an adjustment and fixing structure 200.

[0024] Please see Figure 1 and Figure 2 The support structure 100 includes a support frame 110, a lower support plate 120 and an upper cover plate 130. The support frame 110 is fixed to the lower support plate 120, and the upper cover plate 130 is installed on the lower support plate 120 through a connector 140.

[0025] The support frame 110 includes a horizontal plate 111, on which vertical plates 112 are symmetrically fixed. The vertical plates 112 are fixed to the lower support plate 120. Nail holes 113 are provided on both sides of the horizontal plate 111, allowing for easy connection with external screws or bolts for fixation. First notches 121 are provided on both sides of the lower support plate 120, and second notches 131 matching the first notches 121 are provided on both sides of the upper cover plate 130. The connector 140 includes ear plates 141, symmetrically fixed on both sides of the second notches 131. Threaded posts 142 are rotatably connected between the ear plates 141, engaging with the first notches 121. A nut 143 is threaded to the end of the threaded post 142. The connector 140 connects the lower support plate 120 and the upper cover plate 130, facilitating assembly and disassembly.

[0026] Please see Figures 1-4 The adjusting and fixing structure 200 is circumferentially installed on the lower support plate 120 and the upper cover plate 130. The adjusting and fixing structure 200 includes a threaded rod 210, a fixing plate 220 and a limiting member 230. The threaded rod 210 is threaded through the lower support plate 120 and the upper cover plate 130. The fixing plate 220 is rotatably connected to one end of the threaded rod 210. Extension plates 221 are fixed on both sides of the fixing plate 220. The limiting member 230 is circumferentially fixed between the extension plate 221, the lower support plate 120 and the upper cover plate 130.

[0027] Both the lower support plate 120 and the upper cover plate 130 have threaded holes that match the threaded rod 210. The other end of the threaded rod 210 is keyed to a rotating handle 211. The threaded holes here allow the threaded rod 210 to extend and retract easily, while the rotating handle 211 allows the threaded rod 210 to be rotated easily.

[0028] The limiting member 230 includes a first fixed seat 231 and a second fixed seat 232. The first fixed seat 231 is fixed to both sides of the lower support plate 120 and the upper cover plate 130, and the second fixed seat 232 is fixed to the extension plate 221. A telescopic part 233 is installed between the first fixed seat 231 and the second fixed seat 232. The telescopic part 233 includes a sleeve 2331 and a telescopic rod 2332. The sleeve 2331 is rotatably connected to the first fixed seat 231, and a sliding plate 233 is fixed to one end of the telescopic rod 2332. 3. The sliding plate 2333 is slidably connected inside the sleeve 2331. The other end of the telescopic rod 2332 is rotatably connected to the second fixed seat 232. A spring 2334 is also sleeved on the telescopic rod 2332. The spring 2334 is located on one side of the sliding plate 2333. Here, the extension and retraction of the limiting member 230 can limit the fixed plate 220 and the extension plate 221, which is conducive to the back and forth movement of the fixed plate 220 and the extension plate 221 and their close contact with the pipeline, thereby improving the stability of the installation and fixing.

[0029] Specifically, the working principle of this adjustable inner diameter pipe installation and fixing device is as follows: During use, the threaded rod 210 can be rotated by rotating the handle 211 according to the pipe specifications, causing the threaded rod 210 to move back and forth on the lower support plate 120 and the upper cover plate 130. In this way, the fixing plate 220 and the extension plate 221 will move back and forth with the threaded rod 210 under the action of the limiting member 230, thereby changing the inner diameter formed by multiple fixing plates 220 and multiple extension plates 221. After reaching the appropriate position, the upper cover plate 130 is locked onto the lower support plate 120. At this time, the threaded post 142 is locked onto the second notch 131 and tightened with the nut 143. In this way, it is easier to deal with different specifications of pipes during the pipe installation and fixing process, thereby improving the flexibility of use and the convenience of operation. At the same time, the extension plate 221 can increase the contact area with the pipe, making the installation and fixing more stable.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
