It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and implementation methods. It should be understood that the implementation methods described herein are only used to explain this application and are not used to limit this application.

[0020] The utility model provides the following Figure 1 , Figure 2 , Figure 3 , Figure 4 A metal pipe connection structure is shown, comprising a first connecting ring 1 and a second connecting ring 2, wherein the first connecting ring 1 is fixedly connected to a first connecting flange 3 on a side away from the second connecting ring 2, and the second connecting ring 2 is fixedly connected to a second connecting flange 4 on a side away from the first connecting ring 1, two rotating clamps 5 are fixedly connected to the outer side of the first connecting ring 1, and two clamping grooves 6 cooperating with the rotating clamps 5 are provided on the inner side of the second connecting ring 2, and limiting components 7 are provided at the two clamping grooves 6 on the second connecting ring 2.

[0021] like Figure 1 , Figure 2 , Figure 3 As shown, in the present invention, a plurality of mounting holes 8 are provided on the first connecting flange 3 and the second connecting flange 4 to facilitate the installation of the metal pipe.

[0022] like Figure 1 As shown, in the present invention, an opening for the rotating block 5 to pass through is provided at the clamping groove 6 on the inner side of the second connecting ring 2, so as to facilitate the rotating block 5 to enter the clamping groove 6 to connect the first connecting ring 1 and the second connecting ring 2.

[0023] like Figure 3 and Figure 4 As shown, the limit assembly 7 in the utility model includes a limit box 7.1 embedded in the second connecting ring 2, a fixed block 7.2 is fixedly connected in the limit box 7.1, a limit block 7.3 is slidably connected in the limit box 7.1, a connecting rod 7.4 that passes through the fixed block 7.2 is fixedly connected to one side of the limit block 7.3, a pulling block 7.5 is fixedly connected to one end of the connecting rod 7.4, the limit block 7.3 and the fixed block 7.2 are connected by a spring 7.6 sleeved on the outside of the connecting rod 7.4, a limit groove 7.7 that cooperates with the limit block 7.3 is provided on the rotating clamping block 5, a slider 7.8 is fixedly connected to the top of the limit block 7.3, a slide groove 7.9 for the slider 7.8 to slide is provided on the top wall of the limit box 7.1, and a through hole for the connecting rod to pass is provided on the fixed block 7.2; the surface of the limit block 7.3 close to the opening is an inclined surface.

[0024] The rotation block 5 is limited and fixed by the limit assembly 7. When the rotation block 5 enters the clamping groove 6 and rotates, the rotation block 5 contacts the limit block 7.3 and squeezes it. Since one side of the limit block 7.3 is an inclined surface, the limit block 7.3 slides to one side after being squeezed and slides into the inside of the limit box 7.1. At this time, the spring 7.6 is in a compressed state, and the rotation block 5 continues to rotate until the limit groove 7.7 on the rotation block 5 rotates to the limit block 7.3. At this time, the rotation block 5 does not When the limit block 7.3 is squeezed, the elastic potential energy of the spring 7.6 will restore it to its original state, so that the limit block 7.3 moves into the limit groove 7.7 to limit and fix the rotating block 5, thereby improving the stability of the connection; when disassembling it, the pull block 7.5 is pulled in the same way, and the limit block 7.3 is driven to move through the connecting rod 7.4 and moved to the inside of the limit box 7.1. At this time, the first connecting ring 1 is rotated in the opposite direction to make the rotating block 5 rotate in the opposite direction to the opening, so that the first connecting ring 1 and the second connecting ring 2 are disassembled.

[0025] Working principle: When the utility model is implemented, the first connecting flange 3 and the second connecting flange 4 are respectively connected to the ports of two metal pipes. When connecting the two metal pipes, the rotating block 5 on the outside of the first connecting ring 1 is first aligned with the opening on the inside of the second connecting ring 2, and then the rotating block 5 is inserted into the clamping groove 6 through the opening, and then the first connecting ring 1 is rotated to make the rotating block 5 rotate in the clamping groove 6, and the rotating block 5 is limited and fixed by the limiting component 7 on the second connecting ring 2, thereby improving the stability of the connection.

Although the present invention has been described in detail with reference to the aforementioned implementation modes, a person skilled in the art should understand that the technical solutions described in the aforementioned implementation modes can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the implementation modes of the present invention.
