Detailed Description

Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

In the related art, when a new structure is installed each time, the flange nut needs to be screwed out, which can seriously affect the air tightness of equipment; according to the flange transition bolt provided by the embodiment of the utility model, the bottom of the nut is provided with the cavity by arranging the nut and the threaded rod, the cavity wall of the cavity is provided with threads so as to be connected with the existing flange bolt by the cavity with the threads, the threaded rod is arranged on the upper part of the nut, and the threaded rod is used for being matched with the matched nut so as to fix the structure to be added with the existing flange bolt; therefore, when a new structure is installed, the air tightness of the old equipment is guaranteed.

In order to better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.

Fig. 1 is a schematic structural diagram of a flange over-bolt according to an embodiment of the present invention, as shown in fig. 1, the flange over-bolt includes a nut 10 and a threaded rod 20.

The bottom of the nut 10 is provided with a concave cavity 11, and the cavity wall of the concave cavity 11 is provided with threads, so that the existing flange bolt 30 can be connected through the concave cavity 11 with the threads; that is, as shown in fig. 2, the cavity 11 is tightened onto the existing flange bolt 30 already installed on the equipment to bolt the flange over onto the existing flange bolt 30 already installed; the threaded rod 20 is arranged at the upper part of the nut cap 10, and the threaded rod 20 is used for matching with the adaptive nut 40 to fix the structure to be added and the flange excessive bolt (wherein, the structure to be added is not shown in the figure, and the gap between the adaptive nut 40 and the nut cap 10 is the installation position of the structure to be added); that is, after the flange over-bolts are fastened to the installed existing flange bolts 30 through the cavities 11, the mounting holes of the structure to be added may be installed on the threaded rods 20, and further, after the flange over-bolts are fastened by the fitting nuts 40, the structure to be added may be indirectly fastened to the installed existing flange bolts 30.

It should be noted that, in the installation process of the equipment, in order to ensure the air tightness of the equipment, the specification and the size of the flange bolt selected in the installation process are often large. When the structure is added, the stability of the structure is only required to be ensured, so that the specification and the size are not required to be large. Therefore, when the flange excessive bolts are arranged, the specification of the concave cavity 11 is set to be matched with the specification of the existing flange bolts; and the size of the threaded rod 20 is smaller than that of the conventional flange bolt.

In some embodiments, the existing flange bolts are M16 flange bolts and the mating nuts are M12 hex nuts.

In some embodiments, the length of threaded rod 20 is greater than the depth of cavity 11. It will be appreciated that the existing flange bolts are removed from the area covered by the existing flange nuts after installation of the equipment is complete; the length that can be used for the installation is shorter, often is not suitable for the installation newly-increased structure. Therefore, the length of the threaded rod 20 is greater than the depth of the cavity 11, which corresponds to the lengthening of the existing flange bolt by the flange over-bolt.

In some embodiments, nut 10 is a hex nut.

In some embodiments, the flange over bolts are subjected to a sharp angle removing process, a deburring process and a sharp edge removing process to remove sharp angles, burrs and sharp edges of the flange over bolts; so that the flange excessive bolt edge is more rounded; to prevent sharp corners, burrs and sharp edges from scratching the user.

In summary, according to the flange transition bolt provided by the embodiment of the present invention, by providing the nut and the threaded rod, the bottom of the nut is provided with the cavity, the cavity wall of the cavity is provided with the threads so as to connect the existing flange bolt through the cavity with the threads, the threaded rod is arranged on the upper portion of the nut, and the threaded rod is used for cooperating with the matched nut to fix the structure to be added with the existing flange bolt; therefore, when a new structure is installed, the air tightness of the old equipment is guaranteed.
