It will also be understood that the terms “comprising” and / or “having” as used in this specification specify the presence of the described features, numbers, steps, operations, components, elements or combinations thereof, without excluding the presence or addition of one or more other features, numbers, steps, operations, components, elements or groups thereof.

[0019] refer to Figures 1 to 2 According to a preferred embodiment of the flange pin positioning mechanism of the present invention, it should be noted that the structure of the flange pin positioning mechanism is as follows: Figure 1 As shown, it is mounted on an outer flange 10. Those skilled in the art should understand that the outer flange 10 has an opening and a cavity 101, the opening being connected to the cavity 101 and also connected to the outside.

[0020] It is worth mentioning that the flange pin positioning mechanism includes an annular fixing ring 20, which is fixed to the bottom wall of the cavity 101. Specifically, the bottom wall of the cavity 101 has an annular mounting groove 102, and the annular fixing ring 20 can be directly placed in the annular mounting groove 102 to position the annular fixing ring 20. The connection between the annular fixing ring 20 and the inner wall of the outer flange 10 can be implemented as a welded connection, thereby defining the annular fixing ring 20.

[0021] It is worth mentioning that the wall surface forming the annular mounting groove 102 has a plurality of evenly distributed first mounting holes 103, and the annular fixing ring 20 has a plurality of evenly distributed second mounting holes 201, and the plurality of second mounting holes 201 correspond one-to-one with the plurality of first mounting holes 103.

[0022] It is worth mentioning that the flange pin positioning mechanism also includes a plurality of pin assemblies 30, which respectively cooperate with a plurality of first mounting holes 103, and the other end of each pin assembly passes through the corresponding second mounting hole 201 and is located in the cavity 101.

[0023] Each of the aforementioned pin assemblies 30 includes an elastic element 31 and a pin rod 32. One end of the elastic element 31 is placed on the bottom wall of the first mounting hole 103, and the other end engages with the pin rod 32. The end of the pin rod 32 engaging with the elastic element 31 is located in the first mounting hole 103. The end of the pin rod 32 facing away from the elastic element 31 passes through the second mounting hole 201 and is located within the cavity 101. The connection between the elastic element 31 and the pin assembly can be implemented as a contact fit or welding fixation. The size of the first mounting hole 103 is smaller than the size of the second mounting hole 201. That is, after the first mounting hole 103 and the second mounting hole 201 are simultaneously formed by an external drill bit, the size of the second mounting hole 201 will be enlarged to facilitate the subsequent installation of the pin assembly 30 and the movement of the pin rod 32, preventing the pin rod 32 from getting stuck.

[0024] It is worth mentioning that each of the aforementioned pin assemblies 30 also includes a limiting ring 33, which is threadedly connected to the second mounting hole 201. The position of the limiting ring 33 is then directly fixed by welding. To ensure that the second mounting hole 201 can penetrate the annular fixing ring 20 after being enlarged, the enlargement is performed on the bottom wall forming the cavity 101, so that the first mounting hole 103 becomes a stepped hole. In addition, the center of the limiting ring 33 has a connecting hole, which is directly opposite the corresponding first mounting hole 103. The pin rod 32 has a rotating part 321 and an extension part 322. The rotating part 321 is connected to the extension part 322, which is integrally formed by machining. Furthermore, the cross-sectional dimension of the rotating part 321 is larger than that of the extension part 322.

[0025] Specifically, the size of the connecting hole is also larger than the size of the first mounting hole 103, and the rotating part 321 is configured to be rotatably connected to the connecting hole so as to pass through the connecting hole and be placed inside the first mounting hole 103. The end of the elastic member 31 cooperates with the rotating part 321, and the extension part 322 passes through the connecting hole and is placed on the outside.

[0026] Furthermore, the pin assembly 30 also includes a guide rod 34, which is fixed to the bottom wall forming the first mounting hole 103. The elastic element 31 is sleeved on the guide rod 34, and the rotating part 321 has a movable hole at its end opposite to the extension part 322. The end of the guide rod 34 is slidably connected to the movable hole. That is, the diameter of the movable hole is larger than the cross-sectional size of the guide rod 34, and the guide rod 34 can be fixed to the bottom wall forming the first mounting hole 103 by a threaded connection, i.e., by drilling a threaded hole at the bottom of the first mounting hole 103 to facilitate the installation of the guide rod 34. Those skilled in the art should understand that when the rotating part 321 passes through the connecting hole, the rotating part 321 is slidably connected to the first mounting hole 103. That is, the rotating part 321 can compress the elastic member 31 so that the end of the extension part 322 away from the rotating part 321 can be directed towards or away from the annular fixing ring 20, so that the subsequent plurality of pins 32 cooperate with the corresponding external hole structure to define the position of the external flange 10.

[0027] It is worth mentioning that, in this embodiment, the flange pin positioning mechanism has a simple structure, does not involve complex manufacturing processes or expensive materials, and is highly economical. At the same time, for manufacturers, the flange pin positioning mechanism provided in this application is easy to produce and inexpensive, which is more conducive to controlling production costs and further facilitates product promotion and use.

[0028] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The function and structural principle of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from these principles.
