Description

Technical Field

[0001] This utility model belongs to the field of flange technology, and specifically relates to a flange structure for connection and sealing. Background Technology

[0002] The term "flange" is a general term, usually referring to a disc-shaped metal body with several holes around its perimeter for fixing and connecting other things. This type of object is widely used in machinery.

[0003] Existing flanges are installed by simply closing the flange and inserting bolts through the mounting holes into the internal threaded holes. This makes it easy to fix the flange in place. However, after the flange is fixed, it is not convenient to reinforce the fixing bolts. When subjected to external forces or vibrations after installation, some bolts may loosen, and in severe cases, bolts may fall off, reducing the stability of the installation. Loose areas result in poor sealing, affecting the stability of the flange during fixed installation. Therefore, this utility model proposes a flange structure for connection and sealing. Utility Model Content

[0004] The purpose of this utility model is to provide a flange structure for connection and sealing, so as to solve the problems mentioned in the background art, which are that after the flange is fixedly installed, it is not convenient to strengthen the fixing bolts. When the flange is subjected to external force or vibration after installation, the bolts will loosen locally, and in severe cases, the bolts will fall off, reducing the stability of the installation and resulting in poor sealing at the loose parts.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flange structure for connection and sealing, comprising a flange structure body, the flange structure body including a main plate, an extension ring integrally provided on the upper surface of the main plate, mounting holes equally spaced along the edge of the main plate, and the flange structure body further comprising:

[0006] A reinforced fixing mechanism is provided, which includes a pushing component located inside the main disk on one side of the mounting hole, a compression reinforcing component provided on one end side of the pushing component, a limit reset component provided on the lower surface of the compression reinforcing component, and a clamping adjustment component provided on the upper surface edge of the main disk.

[0007] A reinforced connection sealing mechanism is provided, and the reinforced connection sealing mechanism includes a rotary mounting assembly disposed on the outer surface of an extension ring, wherein the outer surface of the rotary mounting assembly is provided with a reinforced sealing assembly.

[0008] Preferably, the pushing component includes a downward control groove formed on one side of the mounting hole, an inclined push plate is provided inside the downward control groove, a push rod is provided at the top of the inclined push plate, and a ball bearing rolls on one side of the bottom end of the inclined push plate.

[0009] Preferably, the compression reinforcement assembly includes an anti-slip reinforcement plate slidably connected to one side of the downward control groove, the end surface of the anti-slip reinforcement plate being in contact with the surface of the ball.

[0010] Preferably, the limiting reset assembly includes a limiting groove formed at the bottom of the lower control groove, a limiting block is fixed to one end of the lower surface of the anti-slip reinforcement plate, the limiting block is slidably connected to the inside of the limiting groove, and a reset spring is fixed at the connection between the side of the limiting block and the end of the limiting groove.

[0011] Preferably, the clamping adjustment assembly includes an internally threaded annular groove formed at the edge of the upper surface of the main disc, and the end of the push rod extends into the interior of the internally threaded annular groove. An externally threaded pressure ring is threadedly connected to the interior of the internally threaded annular groove, and an internal hexagonal groove is formed on the surface of the externally threaded pressure ring.

[0012] Preferably, the rotary mounting assembly includes an external thread structure disposed on the outer surface of the extension ring, and the outer surface of the extension ring is threadedly connected to an internal thread mounting ring via the external thread structure.

[0013] Preferably, the reinforced sealing assembly includes a surrounding sealing ring that is fixedly mounted on the outer surface of the internally threaded mounting ring by screws, and the bottom end of the surrounding sealing ring matches the bottom edge structure of the main disc, and the top end of the surrounding sealing ring contacts the top surface of the extension ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By designing a reinforced fixing mechanism, the rotating external threaded pressure ring can push the push rod and the downward control groove downward. When the downward control groove moves downward, the ball bearings contact the end of the anti-slip reinforcement plate, squeezing and moving the anti-slip reinforcement plate until it is limited and squeezed onto the outer surface of the fixing bolt for reinforcement and installation. At the same time, multiple bolts are reinforced, which facilitates tight clamping and fixing. This makes it less likely for the bolts to loosen from the flange structure body when subjected to external forces and vibrations after the flange structure body is installed, thus improving the reinforcement, fixation and stability of the flange structure body during fixed installation and use.

Detailed Implementation

[0022] 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.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a flange structure for connection and sealing, including a flange structure body 100, the flange structure body 100 including a main plate 101, an extension ring 102 integrally provided on the upper surface of the main plate 101, and mounting holes 103 equidistantly opened on the edge of the main plate 101. The flange structure body 100 is also provided with:

[0024] The strengthening and fixing mechanism includes a pushing component located inside the main plate 101 on one side of the mounting hole 103. A compression reinforcement component is provided on one end of the pushing component. A limit reset component is provided on the lower surface of the compression reinforcement component. A clamping adjustment component is provided on the upper surface edge of the main plate 101. After the flange structure body 100 is installed, the strengthening and fixing mechanism can further strengthen the fixing bolts and flange structure body 100 for more stable use.

[0025] In order to facilitate the pushing, pressing, and reinforcing installation of the anti-slip reinforcement plate 1039 by means of the pushing component, in this embodiment, preferably, the pushing component includes a downward control groove 1034 opened on one side of the mounting hole 103. The downward control groove 1034 is provided with an inclined push plate 1035. The top of the inclined push plate 1035 is provided with a push rod 1033. A ball bearing 1030 rolls on one side of the bottom end of the inclined push plate 1035. When the push rod 1033 and the inclined push plate 1035 are subjected to force and move downward, the ball bearing 1030 is driven to contact the end surface of the anti-slip reinforcement plate 1039 to press and reinforce the anti-slip reinforcement plate 1039.

[0026] In order to facilitate the compression reinforcement installation of the fixing bolts through the compression reinforcement component, in this embodiment, preferably, the compression reinforcement component includes an anti-slip reinforcement plate 1039 slidably connected to one side of the downward control groove 1034. The end surface of the anti-slip reinforcement plate 1039 is in contact with the surface of the ball bearing 1030. When the inclined push plate 1035 moves downward, the ball bearing 1030 contacts the surface of the anti-slip reinforcement plate 1039 and drives the anti-slip reinforcement plate 1039 to be compressed and moved, so as to facilitate the anti-slip reinforcement plate 1039 to be compressed on the surface of the fixing bolt for reinforcement installation.

[0027] In order to facilitate the limited movement and compression reinforcement of the anti-slip reinforcement plate 1039 by means of the limiting and resetting assembly, in this embodiment, preferably, the limiting and resetting assembly includes a limiting groove 1036 formed at the bottom of the lower control groove 1034, a limiting block 1037 is fixed to one end of the lower surface of the anti-slip reinforcement plate 1039, the limiting block 1037 is slidably connected to the inside of the limiting groove 1036, so that when the anti-slip reinforcement plate 1039 moves, the limiting block 1037 can be driven to slide stably within the limiting groove 1036. A reset spring 1038 is fixed at the connection between the side of the limiting block 1037 and the end of the limiting groove 1036, and after being loosened, the deformation of the reset spring 1038 quickly resets the limiting block 1037 and the anti-slip reinforcement plate 1039.

[0028] In order to facilitate the pressing and tightening installation of the push rod 1033 by means of the pressing and adjusting assembly, in this embodiment, preferably, the pressing and adjusting assembly includes an internal threaded annular groove 1031 opened at the edge of the upper surface of the main plate 101, and the end of the push rod 1033 extends into the interior of the internal threaded annular groove 1031. An external threaded pressure ring 1032 is threadedly connected to the interior of the internal threaded annular groove 1031. The surface of the external threaded pressure ring 1032 is provided with an internal hexagonal socket, which facilitates the wrench to engage in the internal hexagonal socket and rotate the external threaded pressure ring 1032. This allows the external threaded pressure ring 1032 to rotate inside the internal threaded annular groove 1031, pressing and tightening the push rod 1033 and the inclined push plate 1035 for installation.

[0029] The reinforced connection sealing mechanism includes a rotary mounting assembly disposed on the outer surface of the extension ring 102. The outer surface of the rotary mounting assembly is provided with a reinforced sealing assembly, which can reinforce the sealing of the flange structure body 100 during fixed installation.

[0030] To facilitate the rotational fixing of the surrounding sealing ring 1021 onto the outer surface of the extension ring 102 via the rotary mounting assembly, and for ease of installation and use, in this embodiment, preferably, the rotary mounting assembly includes an external thread structure 1023 disposed on the outer surface of the extension ring 102. An internal thread mounting ring 1022 is threadedly connected to the outer surface of the extension ring 102 via the external thread structure 1023. The internal thread mounting ring 1022 can be rotated and mounted via the external thread structure 1023, thereby allowing the surrounding sealing ring 1021 to be rotated and mounted for sealing and use.

[0031] To facilitate the reinforced sealing installation of the flange structure body 100 through the reinforced sealing assembly, in this embodiment, preferably, the reinforced sealing assembly includes a surrounding sealing ring 1021 fixedly installed on the outer surface of the internal threaded mounting ring 1022 by screws, and the bottom end of the surrounding sealing ring 1021 matches the bottom edge structure of the main plate 101, and the top end of the surrounding sealing ring 1021 contacts the top surface of the extension ring 102. When the extension ring 102 closes the external mounting point, the end of the surrounding sealing ring 1021 and the outer surface are pressed tightly against the inner bottom end and inner surface of the mounting point for sealing and fixing. The bottom end of the surrounding sealing ring 1021 then seals with the external mounting surface, facilitating simultaneous sealing installation at multiple locations and enhancing the sealing installation.

[0032] The working principle and usage process of this utility model: When using this type of flange structure with connection and sealing, the first step is installation. The internal threaded mounting ring 1022 can be rotated onto the outer surface of the extension ring 102 through the external thread structure 1023, thereby completely closing the surrounding sealing ring 1021 on the outer surface of the extension ring 102. The bottom end of the surrounding sealing ring 1021 is closed to the bottom edge of the main plate 101. During installation, when the extension ring 102 is embedded into the external installation location, the extension ring 102 and the surrounding sealing ring 1021 are engaged at the corresponding external installation location. The end of the surrounding sealing ring 1021 is pressed against the inner surface and bottom end of the installation location. At the same time, after the main plate 101 is closed and fixed, the bottom end of the surrounding sealing ring 1021 tightly presses and seals the main plate 101 with the external installation surface, thereby facilitating the installation of the flange structure body 100 with multiple tight-press sealing and installation, and enhancing the sealing performance of the installation.

[0033] Then, when the flange structure body 100 is installed, after the bolts pass through the mounting holes 103 and are fixedly installed, the wrench engages in the internal hexagonal socket and drives the external thread pressure ring 1032 to rotate inside the internal thread annular groove 1031. When the external thread pressure ring 1032 rotates, it pushes the push rod 1033 and the downward control groove 1034 downward. When the downward control groove 1034 moves downward, it contacts the end of the anti-slip reinforcement plate 1039 through the ball bearing 1030 and squeezes and moves the anti-slip reinforcement plate 1039 until the anti-slip reinforcement plate 1039 is limited and moved inside the limit groove 1036 by the limit block 1037 and squeezed onto the outer surface of the fixing bolt for reinforcement and installation. At the same time, multiple bolts are reinforced, which facilitates tight clamping and fixing. This makes it less likely for the bolts to loosen from the flange structure body 100 when it is subjected to external forces and vibrations after installation, thus improving the reinforcement and stability of the flange structure body 100 during fixed installation and use.
