[0002] A flange, also called a flange plate or flange, is a part used to connect shafts and pipe ends. Currently, flanges are fixed by bolts inserted into corresponding holes. However, most flanges do not have a fastening structure, making it difficult to achieve precise alignment between flanges during installation. The flanges need to be manually supported, and their position is prone to shifting during subsequent installation. Utility Model Content
[0003] The purpose of this invention is to provide a self-fastening flange to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a self-fastening flange, comprising a flange body one, a flange body two being snapped onto one side of the flange body one, a bolt being provided inside the flange body one, a fastening structure being connected to the outside of the flange body one, the fastening structure being rotatably connected to the outside of the flange body two, a self-locking structure being connected to one side of the fastening structure, the fastening structure comprising a rotating ring, a fixed ring, and three limiting rods, a limiting ring being fixedly connected inside the rotating ring, a guide plate being fixedly connected outside the limiting rods, and three arc-shaped grooves and a guide groove being provided inside the fixed ring.
[0005] As a further preferred embodiment of this technical solution, the flange body one is connected to the flange body two by bolts, the limiting ring is rotatably connected inside the flange body two, and the three limiting rods are fixedly connected to one side of the rotating ring.
[0006] As a further preferred embodiment of this technical solution, the fixing ring is fixedly connected to the outer surface of the flange body, and the limiting rod is engaged in the arc-shaped groove.
[0007] As a further preferred embodiment of this technical solution, the guide plate is snapped into the guide groove, and the rotating ring overlaps with the fixed ring.
[0008] As a further preferred embodiment of this technical solution, the self-locking structure includes three fixed posts and three support posts. The three fixed posts are fixedly connected to one side of the fixed ring, and the three support posts are fixedly connected to one side of the fixed ring. The three fixed posts are spaced at the same distance, and the three support posts are spaced at the same distance.
[0009] As a further preferred embodiment of this technical solution, a locking plate is slidably connected to the outside of the fixing column, a fixing plate is fixedly connected to one end of the fixing column, and a spring is sleeved on the fixing column.
[0010] As a further preferred embodiment of this technical solution, the card plate is connected to the fixed plate by a spring, the limiting rod is engaged in the card plate, and the support column is engaged in the card plate.
[0011] This utility model provides a self-tightening flange, which has the following beneficial effects:
[0012] (1) This utility model sets up flange body one, flange body two and fastening structure to fit flange body one and flange body two together, and the limiting rod on the side of the rotating ring will intersect with the arc groove, driving the rotating ring to rotate inside flange body two. The limiting rod and guide plate will slide in the arc groove and guide groove respectively, and the limiting rod and guide plate will slide to the end of the arc groove and guide groove. Through the cooperation between the limiting rod, arc groove, guide groove and guide plate, the flange part can achieve the function of initial fastening between flange body one and flange body two, so that flange body one and flange body two can achieve precise alignment. No manual support is required during installation, reducing labor intensity and avoiding the phenomenon of displacement of flange body one and flange body two during installation.
[0013] (2) By setting a self-locking structure, the present invention applies a pulling force to the card plate. When the card plate slides on the surface of the fixed column, it will drive the spring to deform through the fixed plate. When the limiting rod and the guide plate slide to the end of the arc groove and the guide groove, the card plate is released. After resetting, the card plate will engage with the support column and the limiting rod, thereby locking the rotating ring and preventing the rotating ring from loosening due to external force.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0020] This utility model provides a technical solution: such as Figure 1 and Figure 4 As shown, in this embodiment, a self-fastening flange includes a flange body 1, a flange body 2 is snapped onto one side of the flange body 1, a bolt 3 is provided inside the flange body 1, a fastening structure 4 is connected to the outside of the flange body 1, the fastening structure 4 is rotatably connected to the outside of the flange body 2, a self-locking structure 5 is connected to one side of the fastening structure 4, the fastening structure 4 includes a rotating ring 401, a fixing ring 402 and three limiting rods 404, a limiting ring 403 is fixedly connected inside the rotating ring 401, a guide plate 407 is fixedly connected outside the limiting rods 404, and three arc-shaped grooves 405 and a guide groove 406 are opened inside the fixing ring 402.
[0021] like Figure 1 and Figure 3 As shown, flange body 1 is connected to flange body 2 by bolts 3. The limiting ring 403 is rotatably connected inside flange body 2. Three limiting rods 404 are fixedly connected to one side of the rotating ring 401. The fixing ring 402 is fixedly connected to the outer surface of flange body 1. The limiting rods 404 are engaged in the arc groove 405. The guide plate 407 is engaged in the guide groove 406. The rotating ring 401 overlaps with the fixing ring 402.
[0022] By setting the arc groove 405 and guide groove 406, when flange body 1 and flange body 2 are in contact, the limiting rod 404 on the side of the rotating ring 401 will intersect with the arc groove 405, causing the rotating ring 401 to rotate inside the flange body 2. The limiting rod 404 and guide plate 407 will slide in the arc groove 405 and guide groove 406 respectively, so that the arc groove 405 and guide groove 406 play a certain auxiliary role in the rotation of the rotating ring 401, and prevent the rotating ring 401 from getting stuck with the fixed ring 402 when rotating.
[0023] like Figure 4 As shown, the self-locking structure 5 includes three fixed posts 501 and three support posts 502. The three fixed posts 501 are fixedly connected to one side of the fixed ring 402, and the three support posts 502 are fixedly connected to one side of the fixed ring 402. The three fixed posts 501 and the three support posts 502 are equally spaced. A locking plate 503 is slidably connected to the outside of the fixed posts 501. A fixing plate 504 is fixedly connected to one end of the fixed posts 501. A spring 505 is sleeved on the fixed posts 501. The locking plate 503 is connected to the fixing plate 504 through the spring 505. The limiting rod 404 is locked inside the locking plate 503, and the support posts 502 are locked inside the locking plate 503.
[0024] By setting a self-locking structure 5, a pulling force is applied to the locking plate 503. When the locking plate 503 slides on the surface of the fixed column 501, it will cause the spring 505 to deform through the fixed plate 504. When the limiting rod 404 and the guide plate 407 slide to the end of the arc groove 405 and the guide groove 406, the locking plate 503 is released. After resetting, the locking plate 503 will engage with the support column 502 and the limiting rod 404, thereby locking the rotating ring 401 and preventing the rotating ring 401 from loosening due to external force.
[0025] This utility model provides a self-fastening flange, the specific working principle of which is as follows:
[0026] When the flange is installed and used, flange body 1 and flange body 2 can be fitted together. The limiting rod 404 on the side of the rotating ring 401 will intersect with the arc groove 405, causing the rotating ring 401 to rotate inside the flange body 2. The limiting rod 404 and the guide plate 407 will slide in the arc groove 405 and the guide groove 406 respectively. Then, a pulling force is applied to the clamping plate 503. When the clamping plate 503 slides on the surface of the fixed column 501, it will cause the spring 505 to deform through the fixed plate 504. When the limiting rod 404 and the guide plate 407 slide to the end of the arc groove 405 and the guide groove 406, the clamping plate 503 is released. The clamping plate 503 will be reset by the spring 505. After being reset, the clamping plate 503 will be engaged with the support column 502 and the limiting rod 404.
[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
