Abstract
Description
Technical Field
[0001] This application relates to the technical field of flange plates, and more specifically, to an anti - detachment flange plate. Background Art
[0002] A flange is also called a flange convex disc or a flange. A flange is a part used to connect between shafts and is used for connecting between pipe ends. The existing sealed flange is used in daily use. The main working principle of the flange is that the two sealing surfaces of the bolts squeeze the flange gasket to form a seal.
[0003] The publication number CN218914070U discloses a flange plate. By providing a plurality of oil drainage holes, it is convenient to drain and clean the accumulated oil inside the oil collecting groove. By providing a protective ring, it can prevent the accumulated oil from flowing to one surface of the flange plate through the oil drainage holes before cleaning. By providing an installation groove and a sealing ring, it is convenient to strengthen the sealing effect between the first flange plate and the second flange plate.
[0004] Although the above patent can strengthen the sealing effect between the first flange plate and the second flange plate, only bolts are used for fastening between the first flange plate and the second flange plate. When the flange plate is used for a long time, due to the influence of internal liquid and other medium pressures and the external environment, relative shaking or rotation may occur between the flange plates, which will cause the loosening of fasteners such as bolts for fixing. The relative rotation between the flange plates will also accelerate the loosening of the fasteners, still resulting in a decline in the sealing performance. Summary of the Utility Model
[0005] In order to solve the above problems, this application provides an anti - detachment flange plate.
[0006] The anti - detachment flange plate provided by this application adopts the following technical solutions:
[0007] An anti - detachment flange plate includes a first flange plate. A second flange plate is provided at the bottom of the first flange plate. An anti - detachment component is provided on the outer sides of the first flange plate and the second flange plate.
[0008] There are multiple groups of anti - detachment components. Each group of anti - detachment components includes a limiting member. The inner wall of the limiting member is arc - shaped. Two limiting blocks are provided at both the inner top and inner bottom of the limiting member. Two sliding grooves are provided at the opposite ends of the first flange plate and the second flange plate. Each limiting block is slidably connected to the corresponding sliding groove. Through holes are opened inside the first flange plate, the second flange plate, and the limiting member. A fixing screw is provided inside the through hole. The first flange plate, the second flange plate, and the limiting member are connected by the fixing screw.
[0009] Through the above technical solution, the anti-loosening component can tightly connect the first flange, the second flange and the limiting member together. The limiting member restricts the displacement of the flange in the radial and transverse directions, avoiding shaking and offset, improving the sealing performance, enhancing the stability and reliability of the flange connection, reducing the risk of problems such as leakage caused by displacement, and being applicable to various scenarios requiring stable connection.
[0010] Further, nuts are threadedly connected to both ends of each fixing screw, and every two nuts are respectively in contact with the top and bottom of the corresponding limiting member.
[0011] Through the above technical solution, the nuts are in close contact with the limiting member during the tightening process, ensuring that the limiting member is in close fit with the flange and strengthening the stability of the flange connection.
[0012] Further, anti-loosening patterns are provided on the opposite sides of the first flange and the second flange, and each anti-loosening pattern is a serrated pattern.
[0013] Through the above technical solution, when the first flange has a tendency to rotate relative to the second flange, the mutual blocking between the serrations will generate resistance to prevent the relative rotational displacement between the first flange and the second flange.
[0014] Further, each nut is hexagonal, and friction grooves are provided at both ends of each nut.
[0015] Further, a slider is slidably connected inside each friction groove, and a limiting plug is provided at one end of each slider.
[0016] Further, each limiting plug is L-shaped, and each limiting plug respectively penetrates through the corresponding limiting member.
[0017] Further, a plurality of limiting grooves are provided inside the first flange and the second flange, and the bottom end of each limiting plug is inserted into the corresponding limiting groove.
[0018] Further, the plurality of limiting plugs are used to fix the nuts.
[0019] Through the above technical solution, after the nuts are tightened, the limiting plugs are manually inserted into the limiting grooves to form a lock on the nuts, restricting the rotation of the nuts, maintaining the pre-tightening force, making the flange connection more stable, reducing the possibility of displacement, improving the sealing performance again, and the overall design enhancing the reliability and safety of the flange connection.
[0020] In summary, the present application includes at least the following beneficial technical effects:
[0021] (1) Through the setting of the anti - detachment component, the present utility model can tightly connect the first flange, the second flange and the limiting member together. The limiting member restricts the displacement of the flange in the radial and transverse directions, avoiding shaking and offset, improving the sealing performance, enhancing the stability and reliability of the flange connection, reducing the risk of problems such as leakage caused by displacement, and being applicable to various scenarios requiring stable connection.
[0022] (2) During the tightening process of the hexagonal nuts at both ends of the fixing screw of the present utility model, they are in close contact with the limiting member, ensuring that the limiting member is closely attached to the flange, strengthening the stability of the flange connection. And after the nuts are tightened, the limiting plug is manually inserted into the limiting groove to lock the nuts, restricting the rotation of the nuts, maintaining the pre - tightening force, making the flange connection more stable, reducing the possibility of displacement, and improving the sealing performance again. The overall design enhances the reliability and safety of the flange connection. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0030] Refer to Figures 1 - 5 , an anti - detachment flange, including a first flange 1, a second flange 2 is provided at the bottom of the first flange 1, and an anti - detachment component is provided on the outer sides of the first flange 1 and the second flange 2;
[0031] There are multiple anti - detachment components. Each anti - detachment component includes a limiting member 3. The inner wall of the limiting member 3 is arc - shaped. There are two limiting blocks 9 at both the inner top and inner bottom of the limiting member 3. There are two sliding grooves 6 at the opposite ends of the first flange 1 and the second flange 2. Each limiting block 9 is slidably connected to the corresponding sliding groove 6. Through - holes are provided inside the first flange 1, the second flange 2, and the limiting member 3. A fixing screw 4 is provided inside the through - hole. The first flange 1, the second flange 2, and the limiting member 3 are connected by the fixing screw 4.
[0032] The inner wall of the limiting member 3 is arc - shaped and can fit well on the outer sides of the first flange 1 and the second flange 2. Since the limiting blocks 9 at the top and bottom of its inner wall are slidably connected to the sliding grooves 6 at the opposite ends of the flange, during installation, the limiting blocks 9 are placed into the sliding grooves 6 to achieve preliminary positioning of the limiting member 3, enabling it to slide and adjust along the sliding grooves 6 on the outer sides of the first flange 1 and the second flange 2 to ensure the accurate relative position between the limiting member 3 and the flange.
[0033] When the limiting movement of the limiting member 3 reaches the appropriate position, at this time, the through - holes inside the first flange 1, the second flange 2, and the limiting member 3 are aligned with each other. Then, the fixing screw 4 is inserted into the through - hole, and two nuts 7 are tightened to the corresponding fixing screw 4 through threaded connection so that they are in contact with both ends of the limiting member 3, tightly connecting the first flange 1, the second flange 2, and the limiting member 3 together. Because the limiting member 3 closely fits on the outer sides of the first flange 1 and the second flange 2 and is fixed by the fixing screw 4 and the nuts 7, it restricts the displacement of the first flange 1 and the second flange 2 in the radial and transverse directions, and can prevent the first flange 1 and the second flange 2 from shaking or shifting in the radial and transverse directions, improving the sealing performance.
[0034] Refer to Figures 4 - 5 , nuts 7 are thread - connected to both ends of each fixing screw 4. Two nuts 7 are respectively in contact with the top and bottom of the corresponding limiting member 3. Each nut 7 is hexagonal. Friction grooves 10 are provided at both ends of each nut 7. A slider 11 is slidably connected inside each friction groove 10. A limiting plug 12 is provided at one end of each slider 11. Each limiting plug 12 is L - shaped. Each limiting plug 12 respectively penetrates the corresponding limiting member 3. Multiple limiting grooves 8 are provided inside the first flange 1 and the second flange 2. The bottom end of each limiting plug 12 is inserted into the corresponding limiting groove 8. The multiple limiting plugs 12 are used to fix the nuts 7.
[0035] The nuts 7 at both ends of the fixing screw 4 are connected by threads. During the tightening process, the two nuts 7 are in close contact with the top and bottom of the limiting member 3 respectively. The hexagonal design of the nut 7 facilitates the use of tools such as wrenches to hold the top of the nut 7 for operation. By tightening the nut 7, the limiting member 3 is subjected to pressure from the nut 7, thereby ensuring the close fit between the limiting member 3 and the first flange 1 and the second flange 2, and thus strengthening the stability of the entire flange connection.
[0036] When the nut 7 is tightened, the slider 11 is located at the topmost end of the friction groove 10. There is a certain frictional force between the friction groove 10 and the slider 11. Therefore, the slider 11 will not displace without the action of an external force. At this time, the limiting plug 12 is located at the top of the limiting member 3 and will not affect the tightening of the nut 7.
[0037] After the tightening is completed, the limiting plug 12 is manually moved downward through the limiting member 3 and inserted into the limiting groove 8 of the first flange 1 and the second flange 2, thus forming a lock on the nut 7, which will limit the rotation of the nut 7 and reduce the possibility of the nut 7 rotating during a long period, thereby maintaining the pre-tightening force between the fixing screw 4 and the nut 7, making the connection between the first flange 1 and the second flange 2 more stable, further reducing the possibility of displacement of the first flange 1 and the second flange 2, and improving the sealing performance again.
[0038] Refer to Figures 2 - 3 On the opposite sides of the first flange 1 and the second flange 2 facing each other, anti-loosening threads 5 are provided. Each anti-loosening thread 5 is a serrated thread.
[0039] When the first flange 1 and the second flange 2 are connected together, the serrated anti-loosening threads 5 on the opposite sides of the first flange 1 and the second flange 2 facing each other will engage with each other. The shape characteristics of the serrated threads enable them to form a mechanical interlocking structure when in contact.
[0040] Because the shape of the serrated thread is a regular long-strip triangular tooth-like structure, when the serrated threads on the opposite sides of the first flange 1 and the second flange 2 come into contact with each other, the teeth on the first flange 1 can be inserted into the recessed parts between the teeth of the second flange 2 (similar to a jigsaw puzzle), making the threads of the first flange 1 and the second flange 2 fit together.
[0041] Therefore, when the first flange 1 has a tendency to rotate relative to the second flange 2, the mutual blocking between the teeth will generate resistance to prevent the relative rotational displacement between the first flange 1 and the second flange 2.
[0042] Working principle: First, when installing the anti-loosening flange, place the second flange 2 at the bottom, then place the first flange 1 correspondingly above the second flange 2. Next, pick up the limiting member 3 and align the limiting blocks 9 at the top and bottom of its inner wall with the sliding grooves 6 at the opposite ends of the first flange 1 and the second flange 2 and place them in. At this time, the limiting member 3 can be slid along the sliding groove 6 to adjust its position, ensuring that the limiting member 3 can closely fit on the outside of the first flange 1 and the second flange 2 and the relative position is accurate. When the limiting member 3 moves to the appropriate position, the through holes inside the first flange 1, the second flange 2, and the limiting member 3 are aligned with each other. Then, insert the fixing screw 4 into the through hole, and then screw nuts 7 onto both ends of the fixing screw 4. The nuts 7 are designed in a hexagonal shape, which is convenient for operating with tools such as wrenches. During the process of tightening the nuts 7, the two nuts 7 are in close contact with the top and bottom of the limiting member 3 respectively, so that the limiting member 3 is subjected to the pressure from the nuts 7, thereby ensuring that the limiting member 3 is closely attached to the first flange 1 and the second flange 2. When the nuts 7 are tightened, the slider 11 is at the topmost end of the friction groove 10. At this time, the limiting plug 12 is at the top of the limiting member 3, which does not affect the tightening operation of the nuts 7. After tightening, manually move the limiting plug 12 downward so that it penetrates the limiting member 3 and inserts into the limiting groove 8 inside the first flange 1 and the second flange 2, thus forming a lock on the nuts 7, restricting the rotation of the nuts 7, maintaining the pre-tightening force between the fixing screw 4 and the nuts 7, making the connection between the first flange 1 and the second flange 2 more stable. At the same time, anti-loosening patterns 5 with serrated patterns are provided on the opposite sides of the first flange 1 and the second flange 2 facing each other. When the first flange 1 and the second flange 2 are connected together, the serrated patterns are engaged with each other. Due to their shape characteristics, the serrations on the first flange 1 can be embedded into the recessed parts between the serrations of the second flange 2, forming a mechanical interlocking structure. When the first flange 1 has a tendency to rotate relative to the second flange 2, the mutual blocking between the serrations will generate resistance, preventing the relative rotational displacement between the first flange 1 and the second flange 2.
[0043] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
