DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3 A stainless steel welded air duct structure with a stable connection includes a bracket 1 and a tube body 2 arranged on the inner side of the bracket 1. The inner side of the bracket 1 is provided with a reinforcing structure for improving the stability of the tube body 2.

[0025] like Figure 1 As shown, the reinforcement structure includes a rubber block 3 fixedly connected to the inner top wall and the inner bottom wall of the bracket 1 respectively, a frame 4 fixedly connected to the other side of the rubber block 3, an elastic telescopic rod 5 fixedly connected to the inner side of the frame 4, a fixing plate 6 fixedly connected to one end of the piston rod of the elastic telescopic rod 5, and a rubber pad 7 fixedly connected to the other side of the fixing plate 6.

[0026] The upper surface of the top frame 4 is provided with a reinforcing component for further improving the connection stability.

[0027] It should be noted that the bracket 1 is composed of a bottom plate 101, a top plate 102 and four support rods 103, and the four support rods 103 are respectively fixedly connected to the four corners of the upper surface of the bottom plate 101, and the top plate 102 is fixedly connected between the top ends of the four support rods 103, the top frame 4 is fixedly connected to the bottom of the top rubber block 3, the bottom frame 4 is fixedly connected to the upper surface of the bottom rubber block 3, the top elastic telescopic rod 5 is fixedly connected to the inner top wall of the top frame 4, the bottom elastic telescopic rod 5 is fixedly connected to the inner bottom wall of the frame 4, the bottom of the top frame 4 is provided with a movable opening adapted to the fixed plate 6, and the upper surface of the bottom frame 4 is provided with a movable opening adapted to the fixed plate 6.

[0028] The strengthening component includes two threaded tubes 8 fixedly connected to the upper surface of the top frame 4, a threaded shaft 9 threadedly connected to the inner side of the threaded tube 8, a connecting plate 10 rotatably connected to the bottom end of the threaded shaft 9, and a first fixing frame 11 fixedly connected to the bottom of the connecting plate 10. The two threaded tubes 8 are respectively located on the left side and the right side of the top rubber block 3. The bottom end of the threaded shaft 9 sequentially penetrates the upper surface of the top frame 4 and the bottom of the top frame 4 and is rotatably connected to the corresponding connecting plate 10. The left side of the upper surface of the bottom frame 4 and the right side of the upper surface of the bottom frame 4 are fixedly connected with a second fixing frame 12. The left first fixing frame 11 corresponds to the left second fixing frame 12 up and down, and the right first fixing frame 11 corresponds to the right second fixing frame 12 up and down.

[0029] In addition, the tube body 2 is composed of two short tubes and two flanges, and the two tube bodies 2 are connected to each other through the flanges. The reason why the rubber block 3 is provided in the present technical solution is that the rubber block 3 can absorb the vibration generated during the use of the tube body 2.

[0030] The working principle of the above embodiment is:

[0031] First, two short tubes are connected to form a tube body 2 through a flange, and then the fixing plate 6 is squeezed and the tube body 2 is placed on the inner side of the second fixing frame 12, and then the fixing plate 6 is loosened. Under the action of the reset deformation characteristics of the elastic telescopic rod 5, the fixing plate 6 moves closer to the position of the flange of the tube body 2, and the fixing plate 6 then drives the rubber pad 7 to press against the flange of the tube body 2. When both the upper and lower sides of the flange are pressed, the flange can more evenly disperse various forces from the pipeline or equipment. This force dispersion effect enables each connection point to bear a relatively small force, thereby reducing the risk of single-point overload and improving the stability of the entire connection. Secondly, firmly pressing against the upper and lower sides of the flange helps to eliminate gaps and looseness at the connection. By firmly pressing against the upper and lower sides of the flange, it can be ensured that the connection always remains tightly fitted, eliminating gaps and looseness, thereby improving the stability of the connection.

[0032] Subsequently, the threaded shaft 9 is rotated, and the threaded shaft 9 moves downward on the inner side of the threaded tube 8. In the process of moving downward, the threaded shaft 9 drives the connecting plate 10 to move downward, and the connecting plate 10 drives the first fixing frame 11 to move downward and contact with the tube body 2, and then the tube body 2 is clamped by the second fixing frame 12, so as to achieve fixed support for the tube body 2.

[0033] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
