[0017] In the description of the utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc., should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components; a fixed connection can be welding or gluing. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0018] like Figure 1The multi-end movable connection structure shown includes a tube body 1, which is a hollow metal tube structure. The two ends of the tube body 1 are respectively connected to a first connecting ring 2, and the first connecting ring 2 is a metal ring with a concave cross-section. The central outer side of the tube body 1 is wrapped with a second connecting ring 3. The second connecting ring 3 is two metal rings symmetrically arranged up and down. A connecting block 4 is connected to one side of the metal ring, and the second connecting ring 3 is connected to the limiting groove 7 on one side, and the other side is connected to the first connecting column 5 through the connecting block 4. The center line of the first connecting column 5 is perpendicular to the center line of the tube body 1. One side of the limiting groove 7 is connected to the slide groove 8, and the end of the slide groove 8 is connected to the second connecting column 10. The center line of the second connecting column 10 is perpendicular to the center lines of the tube body 1 and the first connecting column 4.

[0019] The upper and lower connecting pipes of the tube body 1 realize the gas-liquid transportation function. The ends of the movable parts that move left and right are inserted into the limit groove 7 to limit the left and right movable space. The first connecting column 4 is connected to the groove body on the external movable part to limit the movable range of the movable part. The slide groove 8 limits the forward and backward movement range of the movable part. The second connecting column 10 is connected to the groove body on the external movable part to limit the movable range of the movable part. The entire structure can be connected and limited in multiple directions and directions, realizing the integration of the connection structure and the reasonable planning of the space.

[0020] A first connecting hole 6 is provided on the inner edge of the first connecting ring 2. The center line of the first connecting hole 6 is parallel to the center line of the tube body 1. The first connecting hole 6 passes through the tube body 1 to facilitate the connection of the pipes at the upper and lower ends of the tube body 1. After the interface of the pipe wraps around the first connecting ring 2, it is fastened with a connecting piece through the first connecting hole 6 to avoid the fastener being too large and affecting the adjacent structure.

[0021] The second connecting post 10 is provided with a second connecting hole 11 , which can facilitate the connection and fixation between the second connecting post 10 and other movable parts.

[0022] The chute 8 is a metal structure with a concave shape in longitudinal section. The notch depth is low at one end of the chute 8, and the notch depth is high at the end connected to the second connecting column 10. The bottom surface of the chute 8 forms a step or a slope to avoid liquid accumulation in the chute 8. The structure of the chute 8 with one end higher and the other end lower serves to strengthen the chute structure, increase the contact area at the connection end with the second connecting column 10, and avoid deformation during the connection process with the second connecting column 10.

[0023] A baffle 9 is provided between the slide groove 8 and the second connecting column 10. The baffle 9 can evenly distribute the force of the second connecting column 10, increase the contact area, and enhance the stability of the overall structure. The baffle 9 is a circular metal sheet to reduce the contact of sharp edges with surrounding components.

[0024] One end of the first connecting column 4 is connected to the connecting block 12 , and the other end is provided with a circle of annular groove 5 to facilitate the fitting connection.

[0025] The diameter of the end of the tube body 1 connected to the second connecting ring 3 is smaller than the diameters of the two ends of the tube body 1 , which on the one hand increases the pressure in the tube body 1 and on the other hand reduces the space occupied by the overall structure.

[0026] The limiting groove 7 is a tubular structure with one end open and the other end closed. The side of the limiting groove 7 is connected to the second connecting ring 3. The longitudinal section of the limiting groove 7 is rectangular, which limits the upward, downward, leftward and rightward movement range of the movable part.

[0027] The above description is based on the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the content of the specification. Its technical scope must be determined according to the scope of the claims.
