Description

Technical Field

[0001] This utility model relates to flange bolts, and more particularly to a flange bolt with a modular assembly. Background Technology

[0002] A flange bolt is a fastener specifically designed to connect two flanges (i.e., round or square plates with bolt holes). Its main characteristic is that it is typically used to provide a robust and sealed connection in environments requiring high pressure, high temperature, or high sealing performance. The design of a flange bolt may include a head, a shank, and a flange face (also known as a gasket or integrated gasket) that may be located below the head. This flange face helps to distribute pressure and protect the joined surfaces from damage.

[0003] However, most existing flange bolts are designed as a single unit and cannot be disassembled. As a result, they may wear out in different locations during long-term use and become unusable. They are also inconvenient to carry. Therefore, how to make flange bolts separable to facilitate disassembly and assembly has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a combined assembly flange bolt that separates the flange bolt components by separating the head from the installation section, thereby extending the service life of the undamaged parts.

[0005] To achieve the above objectives, this utility model provides the following technical solution: it includes a head, a rod, and a washer located between the head and the rod. The head is located above the rod, and the rod extends axially up and down. The rod includes, from top to bottom, an installation section, a connecting section, and a mating section. The mating section is provided with an external thread in the circumferential direction. The connecting section is inserted into the head, and the installation section is detachably connected to the head.

[0006] The present invention is further configured such that: the head is provided with an installation groove for the installation segment to be inserted; both the installation segment and the connecting segment are made of rubber; the installation segment is hexagonal prism and its bottom surface abuts against the inner wall of the head; the interior of the installation segment is hollow; the connecting segment is cylindrical and the head is provided with a connecting groove corresponding to the connecting segment; the head is provided with a plurality of connecting blocks for inserting the connecting segment around the circumference of the installation groove, and the installation segment is provided with a connecting slot corresponding to each connecting block.

[0007] The present invention is further configured such that each of the connecting blocks is an arc shape with the opening facing outward.

[0008] The present invention is further configured to include an adjustment module for limiting the installation section, wherein there are two adjustment modules arranged symmetrically.

[0009] The present invention is further configured such that each of the adjustment modules includes an adjustment rod, a limiting block fixedly installed on one side of the adjustment rod, an adjustment disc fixedly installed on the other side of the adjustment rod, and a spring sleeved on the adjustment rod. The adjustment disc abuts against the head, and one end of the spring is fixedly connected to the limiting block while the other end is fixed to the inner wall of the head.

[0010] The present invention is further configured such that each of the limiting blocks is a trapezoidal shape with a narrower top and a wider bottom, and each limiting block includes an inner inclined surface.

[0011] The present invention is further configured to include a cover sleeve, the cover sleeve being made of rubber and having a head attached, and the bottom of the cover sleeve having a disassembly groove.

[0012] By adopting the above technical solution, since the bottom surface of the hexagonal prism-shaped installation section abuts against the inner wall of the head and is located above the connecting section, the installation section needs to be deformed under force during the assembly and connection of the rod with the head to forcibly pass through the connecting groove and be located in the installation groove. At this time, without the action of external force, the installation section cannot pass through the connecting groove downward to determine the relative position of the head and the rod. During the process of the connecting section being inserted into the connecting groove, it needs to forcibly pass through each connecting block so that each connecting block is inserted into the connecting section. At this time, the connecting section cannot rotate relative to the head, thus completing the connection between the rod and the head. When rotating the mating section, there will be no relative rotation between the components. In addition, since the interior of the installation section is hollow, it can facilitate the deformation of the installation section during the process of passing through the connecting groove.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-6 As shown, this utility model discloses a modular flange bolt, including a head 1, a shank 2, and a washer 3 located between the head 1 and the shank 2. The head 1 is located above the shank 2, and the shank 2 extends axially up and down. By inserting the shank 2 into the flange disc, it can be assembled with a nut (this is prior art and will not be described in detail here). The shank 2 includes, from top to bottom, an installation section 21, a connecting section 22, and a mating section 23. The mating section 23 is provided with an external thread 231 in the circumference. The connecting section 22 is inserted into the head 1, and the installation section 21 is detachably connected to the head 1 by means of fastening or other methods. Since the shank 2 of the flange bolt is divided into three sections, and the top installation section 21 is detachably connected to the head 1, when the flange bolt wears out after long-term use, the installation section 21 can be separated from the head 1, and the damaged head 1 or installation section 21 can be replaced. The undamaged part can be mated with the newly replaced head 1 or installation section 21 and continue to be used, thereby extending the service life of the undamaged part.

[0027] The head 1 is provided with a mounting groove 11 for the mounting section 21 to be inserted. Both the mounting section 21 and the connecting section 22 are made of rubber. The mounting section 21 is hexagonal prism with its bottom surface abutting against the inner wall of the head 1. The interior of the mounting section 21 is hollow. The connecting section 22 is cylindrical, and the head 1 has a connecting groove 13 corresponding to the connecting section 22. Several connecting blocks 12 for inserting the connecting sections 22 are arranged circumferentially around the mounting groove 11 on the head 1, and the mounting section 21 has a connecting slot 211 corresponding to each connecting block 12. Because the bottom surface of the hexagonal prism mounting section 21 abuts against the inner wall of the head 1 and is located above the connecting section 22, during the assembly and connection of the rod 2 with the head 1, the rod 2 is securely mounted. The mounting section 21 needs to be deformed under force to forcibly pass through the connecting groove 13 and then be located in the mounting groove 11. At this time, without the action of external force, the mounting section 21 cannot pass through the connecting groove 13 downward to determine the relative position of the head 1 and the rod 2. During the process of the connecting section 22 being inserted into the connecting groove 13, it needs to forcibly pass through each connecting plug 12 so that each connecting plug 12 is inserted into the connecting section 22. At this time, the connecting section 22 cannot rotate relative to the head 1, thus completing the connection between the rod 2 and the head 1. When rotating the mating section 23, there will be no relative rotation between the components. In addition, since the interior of the mounting section 21 is hollow, it can facilitate the deformation of the mounting section 21 during the process of passing through the connecting groove 13.

[0028] Preferably, each of the connecting blocks 12 is arranged in an arc shape with the opening facing outward. Since the opening of each connecting block 12 is arranged with the opening facing outward, during the process of inserting the connecting segment 22 into each connecting block 12, it can be more smoothly aligned with the corresponding insertion position to complete the insertion of the connecting segment 22.

[0029] In addition, it also includes adjustment modules 4 for limiting the installation section 21. Each adjustment module 4 is located at the head 1. There are two adjustment modules 4 arranged symmetrically. Since each adjustment module 4 is used to limit the installation section 21, the stability of the installation section 21 at the head 1 is further improved.

[0030] Each adjustment module 4 includes an adjustment rod 41, a limiting block 42 fixedly installed on one side of the adjustment rod 41 by welding or other means, an adjustment plate 43 fixedly installed on the other side of the adjustment rod 41 by welding or other means, and a spring 44 sleeved on the adjustment rod 41. The adjustment plate 43 abuts against the head 1. One end of the spring 44 is fixedly connected to the limiting block 42, and the other end is fixed to the inner wall of the head 1. By applying radial (inner and outer) force to each adjustment plate 43, the spring 44 can be compressed or reset, thereby causing each limiting block 42 to abut against the head 1. The installation section 21 can be separated or inserted into different positions. Specifically, when the adjustment plate 43 is moved outward, the adjustment rod 41 and the insert block move outward and compress the spring 44. At this time, the installation section 21 is separated from each limiting insert block 42 and then moves downward across the connecting groove 13 to separate the rod 2 from the head 1. Alternatively, the installation section 21 moves from bottom to top into the installation groove 11. After the force on the adjustment plate 43 is released, each limiting insert block 42 moves inward under the elastic force of the spring 44, thereby inserting the installation section 21 and limiting the installation section 21.

[0031] Preferably, each of the limiting blocks 42 is a trapezoidal shape that is narrower at the top and wider at the bottom, and each limiting block 42 includes an inner inclined surface 421. Since each limiting block 42 is a trapezoidal shape that is narrower at the top and wider at the bottom and has an inner inclined surface 421, it can be inserted into the installation section 21 more smoothly than a block with a flat rectangle on the inner side.

[0032] The system also includes a cover sleeve 5, which is made of rubber and covers the head 1. The inner wall of the cover sleeve 5 is circumferentially fitted to the head 1. The bottom of the cover sleeve 5 is provided with a disassembly groove 51. Since the inner wall of the cover sleeve 5 is circumferentially fitted to the head 1, the cover sleeve 5 cannot rotate relative to the head 1. At the same time, unauthorized personnel cannot directly contact the adjustment disc 43 and thus cannot separate the rod 2 from the head 1. When it is necessary to separate the rod 2 from the head 1, the part of the cover sleeve 5 with the disassembly groove 51 is lifted to deform it and separate it from the head 1.

[0033] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
