[0003] Existing steel pipe connections are generally made by threading an external pipe with the steel pipe, connecting the two stainless steel pipes together while keeping the internal pipes unobstructed. However, the connection strength is low, and the size of the external pipe must be adapted to the size of the stainless steel pipe to avoid gaps, which has certain limitations. Utility Model Content
[0004] The purpose of the utility model is to provide a stainless steel pipe internal connection processing structure to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a stainless steel pipe internal connection processing structure, comprising two steel pipe bodies, each of the two steel pipe bodies is equipped with a connecting plate at one end facing each other, an internal ring is installed at one end of the connecting plate close to the steel pipe body, an external protective shell is installed on the outside of the internal ring and on the same side of the connecting plate, a plurality of sliding grooves are provided between the external protective shell and the internal ring and on the surface of the connecting plate, a plurality of the sliding grooves are internally slidably connected with a movable arc plate, an extension pipe is installed at the other end of the connecting plate, the other end of the extension pipe is set to a threaded surface, and the threaded surfaces of the two extension pipes are threadedly sleeved with threaded rings.
[0006] Preferably, the positions of the plurality of chutes are arranged divergently from the center of the connecting disk.
[0007] Preferably, a plurality of first fixing bolts are installed in an array on the surface of the external protective shell, and the first fixing bolts pass through the external protective shell, the movable arc plate, the steel pipe body and extend to the interior of the internal ring.

[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] 1. This stainless steel pipe internal connection processing structure inserts an internal ring into the interior of the steel pipe body and changes the position of the movable arc plate so that multiple movable arc plates fit the outer surface of the steel pipe body. Multiple first fixing bolts are used to thread through the external protective shell, the movable arc plate, the steel pipe body and the internal ring in sequence. Finally, the threaded collar is threaded on the surface of the two extension pipes, and then the two extension pipes are connected together, so that the two steel pipe bodies are connected together. By setting a movable movable arc plate, the device can be applied to most steel pipe bodies of different sizes. Multiple first fixing bolts can greatly enhance the connection stability between the device and the steel pipe body.
[0013] 2.

[0021] like Figures 1 to 4 As shown, the stainless steel pipe internal connection processing structure of this embodiment includes two steel pipe bodies 1, and a connecting disk 11 is installed at the opposite ends of the two steel pipe bodies 1. The center position of the connecting disk 11 is a hollow circle structure. An internal ring 10 is installed at the end of the connecting disk 11 close to the steel pipe body 1. The size of the internal ring 10 is relatively short, and is consistent with the size of the hollow circle inside the connecting disk 11. They are fixedly connected to each other. An external protective shell 2 is installed on the outside of the internal ring 10 and on the same side of the connecting disk 11. The size of the external protective shell 2 is larger than that of the internal ring 10. The internal ring 10 is located inside the steel pipe body 1, and the external protective shell 2 is located outside the steel pipe body 1. The external protective shell 2 is located between the external protective shell 2 and the internal ring 10 and on the surface of the connecting disk 11. There are multiple slide grooves 12 in the position, and the internal sliding connection of the multiple slide grooves 12 is connected with a movable arc plate 9. The movable arc plate 9 is located at the external position of the steel pipe body 1 and can move along the length direction of the slide groove 12. An extension pipe 6 is installed at the other end of the connecting plate 11. The inner diameter of the extension pipe 6 is consistent with the inner diameter of the built-in ring 10. The other end of the extension pipe 6 is set as a threaded surface 7. The surface of the end of the extension pipe 6 away from the connecting plate 11 is provided with a threaded surface 7. The threaded surfaces 7 of the two extension pipes 6 are threadedly sleeved with threaded rings 8. It should be noted that when installing the threaded ring 8, it is necessary to cover the surface of the two threaded surfaces 7 with a circle of waterproof film, and then the threaded ring 8 is sleeved on the surface of the two threaded surfaces 7 to enhance the waterproof performance.
[0022] Specifically, the positions of the plurality of chutes 12 are arranged in a divergent shape from the center of the connecting disk 11 . When the chutes 12 are extended in the length direction, they are all connected to the center position of the connecting disk 11 .
[0023] Furthermore, a surface array of the external protective shell 2 is installed with a plurality of first fixing bolts 3, which pass through the external protective shell 2, the movable arc plate 9, the steel pipe body 1 and extend to the interior of the internal ring 10. Multiple first fixing bolts 3 are used to thread through the external protective shell 2, the movable arc plate 9, the steel pipe body 1 and the internal ring 10 in sequence, and then the steel pipe body 1 and the internal ring 10, the movable arc plate 9 and the external protective shell 2 are all threaded together, so that the external protective shell 2 can play a certain protective role.
[0024] Furthermore, a reinforcement sleeve 4 is installed on the surface of the threaded collar 8, and the reinforcement sleeve 4 includes a first plate 401 and a second plate 402. The first plate 401 and the second plate 402 have the same size and opposite directions. The two ends of the first plate 401 and the second plate 402 are threadedly connected by multiple second fixing bolts 5. A casting hole 13 is opened on the surface of the reinforcement sleeve 4. By installing the reinforcement sleeve 4 on the outside of the threaded collar 8 and reinforcing it with multiple second fixing bolts 5, and then pouring concrete into the inside of the reinforcement sleeve 4 through the casting hole 13, the concrete will fill the space between the threaded collar 8 and the reinforcement sleeve 4 to form a relatively stable structure, which can largely avoid the phenomenon of liquid inside the steel pipe overflowing from the threaded collar 8.
[0025] The method of using this embodiment is: by inserting the built-in ring 10 into the interior of the steel pipe body 1 and changing the position of the movable arc plate 9, multiple movable arc plates 9 are fit with the outer surface of the steel pipe body 1, using multiple first fixing bolts 3, threading through the external protective shell 2, the movable arc plate 9, the steel pipe body 1 and the built-in ring 10 in sequence, and finally threading the threaded collar 8 on the surface of the two extension pipes 6, and then connecting the two extension pipes 6 together, so that the two steel pipe bodies 1 are connected together. By setting a movable movable arc plate 9, the device can be applied to most steel pipe bodies 1 of different sizes, and multiple first fixing bolts 3 can greatly enhance the connection stability between the device and the steel pipe body 1.
[0026] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
