[0002] The water pipe of an automobile heater is used to discharge the water generated by the automobile heater. During the connection process of the water pipe, a pipeline circular ring is required. Sometimes, the pipeline circular ring is not round during the production process, and in this case, an expander is needed.
[0003] The existing pipeline circular ring expander is inconvenient to operate, has low expansion efficiency, and is prone to pinching hands during the expansion process, posing a certain danger. For this reason, a pipeline circular ring expander is proposed. Summary of the Utility Model
[0004] In view of the problems existing in the above-mentioned existing expander, the present utility model is proposed.
[0005] Therefore, the purpose of the present utility model is to provide a pipeline circular ring expander, which solves the problems raised in the background art.
[0006] In order to achieve the above purpose, the present utility model provides the following technical solutions:
[0007] A pipeline circular ring expander includes a base. On one side of the top of the base, two supports are symmetrically and fixedly arranged. A rotating shaft is rotatably arranged between the two supports. A pressing rod is fixedly arranged on the shaft wall of the rotating shaft. A circular ring expansion plate is fixedly arranged on the rod wall of the pressing rod. A positioning bracket is vertically and fixedly arranged on the top of the base. The rod wall of the pressing rod passes through the inside of the positioning bracket. A circular ring supporting plate is fixedly arranged on the top of the base and inside the positioning bracket.
[0008] Preferably, installation edges are arranged on both sides of the base, and installation holes are opened on the installation edges.
[0009] Preferably, the circular ring expansion plate is an L-shaped plate body, and the circular ring expansion plate is fixedly welded to the pressing rod.
[0010] Preferably, the circular ring supporting plate is an arc-shaped plate body, and the circular ring supporting plate is fixedly welded to the base.
[0011] Furthermore, a limiting opening is opened at the lower end of the vertical part of the circular ring expansion plate. A limiting protrusion is fixedly arranged at one end of the circular ring supporting plate away from the positioning bracket. The limiting protrusion is in snap-fit with the limiting opening.
[0012] Preferably, a fixing sleeve is fixedly welded to one end of the pressing rod, and the fixing sleeve is fixedly arranged on the shaft wall of the rotating shaft.
[0013] In the above technical solution, the technical effects and advantages provided by the present utility model:
[0014] 1. In this utility model, by providing a pressure rod, a circular ring expansion plate, a positioning bracket and a circular ring support plate, the circular ring of the pipeline to be expanded is placed inside the circular ring support plate, so that the convex part of the circular ring of the pipeline to be expanded corresponds to the circular ring expansion plate. Then, the pressure rod is pressed down, so that one end of the pressure rod rotates through the rotating shaft. At this time, the circular ring expansion plate contacts the convex part of the circular ring of the pipeline and presses it flat. During this process, the positioning bracket can play a role in positioning the circular ring of the pipeline, so that the circular ring of the pipeline can be pressed into a circle and expanded at one time, improving the expansion efficiency. Since the length of the pressure rod is large enough and there is a gap between the pressure rod and the base, the phenomenon of pinching hands will not occur, improving the safety of use.
[0015] 2. In this utility model, through the limiting port and the limiting protrusion arranged between the circular ring expansion plate and the circular ring support plate, during the process of expanding the circular ring pipeline by the circular ring expansion plate, the limiting port and the limiting protrusion are clamped and matched, playing a role in limiting at this time and avoiding the phenomenon that the circular ring expansion plate expands the circular ring pipeline excessively.

[0022] In order to enable those skilled in the art to better understand the technical solutions of this utility model, the following will further introduce this utility model in detail in conjunction with the drawings.
[0023] An embodiment of this utility model discloses a pipeline circular ring expander.
[0024] The present utility model provides a pipeline ring expander as shown in Figures 1-3 Figure 1, which includes a base 1. On one side of the top of the base 1, two supports 2 are symmetrically and fixedly arranged. A rotating shaft 3 is rotatably arranged between the two supports 2. A pressure rod 4 is fixedly arranged on the shaft wall of the rotating shaft 3. One end of the pressure rod 4 is fixedly welded with a fixed sleeve 12. The fixed sleeve 12 is fixedly arranged on the shaft wall of the rotating shaft 3, so that one end of the pressure rod 4 rotates through the rotating shaft 3. A circular ring expansion plate 5 is fixedly arranged on the rod wall of the pressure rod 4. The circular ring expansion plate 5 adopts an L-shaped plate body, and the circular ring expansion plate 5 is fixedly welded with the pressure rod 4. A positioning bracket 6 is vertically and fixedly arranged on the top of the base 1. The rod wall of the pressure rod 4 passes through the inside of the positioning bracket 6. Inside the positioning bracket 6 on the top of the base 1, a circular ring support plate 7 is fixedly arranged. The circular ring support plate 7 adopts an arc-shaped plate body, and the circular ring support plate 7 is fixedly welded with the base 1. By placing the pipeline ring to be expanded inside the circular ring support plate 7, the protruding part of the pipeline ring to be expanded corresponds to the circular ring expansion plate 5. Then, the pressure rod 4 is pressed downwards, so that one end of the pressure rod 4 rotates through the rotating shaft 3. At this time, the circular ring expansion plate 5 contacts the protruding part of the pipeline ring and flattens it. During this process, the positioning bracket 6 can play a role in positioning the pipeline ring, so that the pipeline ring can be pressed into a circle and expanded at one time, improving the expansion efficiency. Since the length of the pressure rod 4 is sufficient and there is a gap between the pressure rod 4 and the base 1, the phenomenon of pinching hands will not occur, improving the use safety.
[0025] To increase the stability of use, as shown in Figures 1-2 Figure 2, both sides of the base 1 are provided with mounting edges 8, and mounting holes 9 are opened on the mounting edges 8. By inserting bolts into the inside of the mounting holes 9, the base 1 can be fixed on the mounting surface.
[0026] Finally, to be able to limit the expansion, as shown in Figures 2-3 Figure 3, a limiting port 10 is opened at the lower end of the vertical part of the circular ring expansion plate 5. A limiting protrusion 11 is fixedly arranged at one end of the circular ring support plate 7 away from the positioning bracket 6. The limiting protrusion 11 is in snap-fit with the limiting port 10. During the process of expanding the circular ring pipeline by the circular ring expansion plate 5, the limiting port 10 is in snap-fit with the limiting protrusion 11, playing a role in limiting at this time and avoiding the phenomenon that the circular ring expansion plate 6 expands the circular ring pipeline excessively.
[0027] Only some exemplary embodiments of the present utility model are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
