Description

Technical Field

[0001] The invention relates to the technical field of flange connection, in particular to a rotary self-locking anti-fatigue flange. Background Art

[0002] With the rapid development of science and technology, new design concepts and technologies are constantly emerging in the field of flange connection technology. For example, the research and development of various self-locking flanges have provided certain technical references for the development of rotary self-locking anti-fatigue flanges. For example, some self-locking flanges have achieved rapid connection and locking between flanges through special structural design, thereby improving connection efficiency and sealing. In the use of rotary self-locking anti-fatigue flanges, the self-locking purpose is generally achieved through the movement of the flange neck through its internal ratchet structure. Since the flange is connected to a heavier pipe during use, it is easy to cause the internal ratchet structure on one side of the flange connected to the heavier pipe to jump and wear excessively when the flange rotates during long-term rotation. This affects the self-locking of the flange while affecting the operating efficiency of the heavier pipe. Summary of the Invention

[0003] The object of the present invention is to provide a rotating self-locking anti-fatigue flange to solve the problems raised in the above background technology.

[0004] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0005] The present invention is a rotary self-locking anti-fatigue flange, comprising a main body and:

[0006] An expansion mechanism is installed inside the main body;

[0007] The auxiliary mechanism is fixedly arranged inside the main body.

[0009] A rotating assembly is arranged inside the main body through a fixing member;

[0010] The sliding component is slidably arranged inside the rotating component.

[0011] Furthermore, the expansion mechanism includes a sliding block 1 slidably arranged on the top of the sliding assembly, and the expansion mechanism includes:

[0012] A support assembly is slidably arranged on top of the sliding assembly;

[0013] The clamping assembly is fixedly arranged on the outside of the supporting assembly.

[0014] Furthermore, the auxiliary mechanism includes a fixed ring fixedly arranged inside the rotating assembly, and the auxiliary mechanism includes:

[0015] The swing component is fixedly arranged inside the rotating component.

[0016] Furthermore, the rotating assembly includes a flange rotatably connected to the outer surface of the flange neck, and an annular groove is formed inside the flange;

[0017] The outer surface of the flange neck is fixedly connected to the inner wall of the main body.

[0018] Furthermore, the fixing member includes a gear ring fixedly connected to the inner wall of the annular groove, and the inner wall of the gear ring is meshedly connected with a rotating block;

[0019] Wherein, the inner wall of the rotating block is fixedly connected to the outer surface of the flange neck.

[0020] Furthermore, the sliding assembly includes an arc block 1 fixedly connected to the outer surface of the flange neck, a sliding plate is provided on the outer surface of the arc block 1, the side wall of the sliding plate is slidingly connected to the arc block 2, and two strip grooves are provided on the side of the arc block 2 close to the sliding plate.

[0021] Furthermore, the support assembly includes an arc-shaped rod 1 fixedly connected to a side wall of the sliding block, a side of the arc-shaped rod 1 away from the sliding block 1 is slidably connected to the sliding block 2, and a side of the two sliding blocks 2 close to each other is fixedly connected to an arc spring;

[0022] The outer surface of the sliding block 1 is slidably connected to the inside of the strip groove, and the end of the arc rod 1 connected to the sliding block 1 is rotatably connected to the outer surface of the sliding plate.

[0023] Furthermore, the clamping assembly includes a folding ring fixedly connected to the side of the two sliding blocks that are away from each other. The outer surface of the folding ring is provided with a plurality of rectangular grooves, and the interior of the folding ring is provided with a wave groove.

[0024] Furthermore, the swing assembly includes a rotating bar slidably connected to the side wall of the fixed ring, the inner wall of the rotating bar is rotatably connected to a plurality of arc-shaped rods 2, and the interior of the folding ring is fixedly connected to a plurality of springs;

[0025] Among them, the outer surface of the fixed ring is fixedly connected to the inner wall of the annular groove, one end of the rotating bar is fixedly connected to the side wall of the sliding block 2, and the end of the arc rod 2 away from the rotating bar is slidably connected to the inside of the rectangular groove.

[0026] The present invention has the following beneficial effects:

[0027] 1. The present invention drives the flange neck to rotate by rotating the main body. When the flange neck rotates, the arc block 1 is driven to rotate, thereby contacting the sliding plate and then pushing the sliding plate to slide in the process of continuing to rotate. When the sliding plate slides, the arc rod 1 is pushed to slide and the folding ring is squeezed to shrink the folding ring. When the folding ring shrinks, the internal folding part thereof is bulged to contact the outer surface of the flange neck. In this way, after the flange is connected to a heavier pipe, the internal ratchet structure is easily subjected to the weight of the heavier pipe, which may cause jumping and excessive wear during long-term rotation of the flange. This improves the quality of the internal ratchet structure of the flange during movement and the operating efficiency of the pipeline.

[0028] 2. In the present invention, during the process of the two sliding blocks pushing the folding ring to fold, one of the sliding blocks will synchronously push the rotating bar to rotate around the center of the flange neck on the fixed ring, and then push a plurality of arc rods to slide toward the center of the flange neck inside the rectangular groove. During the sliding process of the arc rods, the folding ring will be squeezed to achieve the effect of fixing the folding ring during the rotation of the flange neck, effectively avoiding the situation where the heavier pipe is driven to rotate and deflected due to the friction of the folding ring caused by excessive rotational force during rotation, further protecting the heavier pipe when it is in operation, and improving the efficiency of the device during operation.

[0029] 3. According to the present invention, the rotation of the flange neck will drive the second sliding block to squeeze the folding ring. In the process of the folding ring being squeezed and folded, the gap of the wave groove becomes larger when the folding ring folds and the squeezing force on the spring is reduced, so that the spring begins to extend and squeezes the folding ring in contact with the outer surface of the flange neck, thereby increasing the friction between the raised part of the folding ring and the outer surface of the flange neck, further slowing down the inertia of the heavier pipe when it rotates through the main body, preventing the flange neck from rotating too fast due to the excessive weight of the heavier pipe, improving the safety of the heavier pipe when it runs through the device, and protecting the overall quality of the heavier pipe during operation.

[0030] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] See also Figures 1-10 As shown, the present invention is a rotating self-locking anti-fatigue flange, comprising a main body 1, and further comprising:

[0046] The expansion mechanism 2 is installed inside the main body 1;

[0047] The auxiliary mechanism 3 is fixedly arranged inside the main body 1. When the main body 1 starts to rotate, it will synchronously drive the expansion mechanism 2 located inside the main body 1 to start running. During the operation of the expansion mechanism 2, it will exert a reaction force on the main body 1 to achieve a buffering effect. During the operation of the expansion mechanism 2, it will drive the auxiliary mechanism 3 to run synchronously.

[0048] The main body 1 includes a flange neck 111 fixedly connected to the interior of the main body 1. The main body 1 includes:

[0049] The rotating assembly 11 is arranged inside the main body 1 through a fixing member;

[0050] The sliding component 12 is slidably arranged inside the rotating component 11. During the operation of the main body 1, the rotating component 11 inside the main body 1 will be driven to start running. During the operation of the rotating component 11, the flange neck 111 inside it will synchronously drive the sliding component 12 inside the rotating component 11 to start running.

[0051] The expansion mechanism 2 includes a sliding block 211 slidably disposed on the top of the sliding assembly 12. The expansion mechanism 2 includes:

[0052] A support assembly 21 is slidably disposed on top of the sliding assembly 12;

[0053] The clamping assembly 22 is fixedly arranged on the outside of the supporting assembly 21. During the operation of the sliding assembly 12, the supporting assembly 21 located on the top thereof will be driven to start synchronous operation. During the operation of the supporting assembly 21, the clamping assembly 22 located on the outside thereof will be driven to start operation.

[0054] The auxiliary mechanism 3 includes a fixed ring 311 fixedly arranged inside the rotating assembly 11, and the auxiliary mechanism 3 includes:

[0055] The swinging assembly 31 is fixedly arranged inside the rotating assembly 11. During the operation of the rotating assembly 11, the swinging assembly 31 located inside the rotating assembly 11 will run synchronously under the drive of the rotating assembly 11. During the operation of the swinging assembly 31, the effect of slowing down the rotating flange neck can be achieved.

[0056] The rotating assembly 11 includes a flange 112 rotatably connected to the outer surface of the flange neck 111 , and an annular groove 113 is formed inside the flange 112 ;

[0057] Among them, the outer surface of the flange neck 111 is fixedly connected to the inner wall of the main body 1. When the flange neck 111 starts to rotate, since the inner wall of the flange plate 112 is rotatably connected to the outer surface of the flange neck 111, when the flange neck 111 is driven to rotate on one side of the main body 1, the flange plate 112 at the other end of the flange neck 111 will be fixed on the heavier pipe, thereby allowing the heavier pipe to operate normally.

[0058] The fixing member includes a gear ring 114 fixedly connected to the inner wall of the annular groove 113, and the inner wall of the gear ring 114 is meshedly connected with a rotating block 115;

[0059] Among them, the inner wall of the rotating block 115 is fixedly connected to the outer surface of the flange neck 111. During the rotation of the flange neck 111, since the flange plate 112 and the gear ring 114 located inside the annular groove 113 do not rotate synchronously, when the flange neck 111 rotates, the rotating block 115 will be driven to contact the gear ring 114 during rotation and self-lock after the rotation is completed.

[0060] The sliding assembly 12 includes an arc block 121 fixedly connected to the outer surface of the flange neck 111, and a sliding plate 122 is provided on the outer surface of the arc block 121. The side wall of the sliding plate 122 is slidably connected to the arc block 2 123. The arc block 2 123 has two strip grooves 124 on one side close to the sliding plate 122. During the rotation of the arc block 121, it will contact the sliding plate 122, thereby pushing the sliding plate 122 to slide from the center of the main body 1 to the outside on the arc block 2 123. During the sliding process of the sliding plate 122 on the arc block 2 123, a thrust will be applied to the arc rod 1 212.

[0061] The support assembly 21 includes an arc-shaped rod 1 212 fixedly connected to the side wall of the sliding block 1 211. The side of the arc-shaped rod 1 212 away from the sliding block 1 211 is slidably connected to the sliding block 213. The sides of the two sliding blocks 213 close to each other are fixedly connected to the arc spring 214.

[0062] Among them, the outer surface of the sliding block 211 is slidably connected to the inside of the strip groove 124, and the end of the arc rod 1 212 connected to the sliding block 1 211 is rotatably connected to the outer surface of the sliding plate 122. When the arc rod 1 212 is pushed on the strip groove 124 to drive the sliding block 1 211 to slide, the sliding block 1 211 will drive one end of the arc rod 1 212 connected to it to slide and then push the end of the arc rod 1 212 away from the sliding block 1 211 to slide on the arc block 2 123, so that the arc rod 1 212 gradually moves to a state parallel to the sliding plate 122. During the sliding process of the arc rod 1 212, the sliding block 213 at the top of the arc rod 1 212 will be driven to slide synchronously. During the sliding process of the two sliding blocks 213, a pulling force will be applied to the arc spring 214 to make it open.

[0063] The clamping assembly 22 includes a folding ring 221 fixedly connected to the side of the two sliding blocks 213 away from each other. The outer surface of the folding ring 221 is provided with a plurality of rectangular grooves 222, and the interior of the folding ring 221 is provided with a wave groove 223. In the process of the two sliding blocks 213 pushing the folding ring 221 to fold, one of the sliding blocks 213 will synchronously push the rotating bar 312 to rotate around the center of the flange neck 111 on the fixed ring 311. In the process of the rotation of the rotating bar 312, it will push a plurality of arc rods 2 313 to slide inside the rectangular groove 222 toward the center of the flange neck 111.

[0064] The swing assembly 31 includes a rotating bar 312 slidably connected to the side wall of the fixed ring 311. The inner wall of the rotating bar 312 is rotatably connected to a plurality of arc-shaped rods 313. The interior of the folding ring 221 is fixedly connected to a plurality of springs 314.

[0065] Among them, the outer surface of the fixed ring 311 is fixedly connected to the inner wall of the annular groove 113, one end of the rotating bar 312 is fixedly connected to the side wall of the sliding block 213, and the end of the arc rod 213 away from the rotating bar 312 is slidably connected to the inside of the rectangular groove 222. When the flange neck 111 rotates and drives the sliding block 213 to squeeze the folding ring 221, the gap of the wave groove 223 becomes larger when the folding ring 221 is folded, and the spring 314 is extended. During the extension of the spring 314, the folding ring 221 in contact with the outer surface of the flange neck 111 will be squeezed, thereby increasing the friction between the raised part of the folding ring 221 and the outer surface of the flange neck 111.

[0066] When in use, when the heavier pipe connected to the main body 1 is rotated, the rotation of the heavier pipe will drive the main body 1 and the side connected to it and the flange neck 111 to rotate synchronously. During the rotation of the flange neck 111, the flange 112 and the gear ring 114 located inside the annular groove 113 will not rotate synchronously. Therefore, when the flange neck 111 rotates, the rotating block 115 will be driven to contact the gear ring 114 during rotation and self-lock after the rotation is completed. During the rotation of the flange neck 111, the arc block 121 will be driven to rotate synchronously. The arc block 121 rotates synchronously. During the rotation of the arc block 121, it contacts the sliding plate 122, thereby pushing the sliding plate 122 to slide from the center of the main body 1 to the outside on the arc block 2 123. During the sliding of the sliding plate 122 on the arc block 2 123, a thrust is applied to the arc rod 1 212. When the arc rod 1 212 is pushed and drives the sliding block 1 211 to slide on the strip groove 124, the sliding block 1 211 drives one end of the arc rod 1 212 connected thereto to slide, thereby pushing the arc rod 1 212 away from the sliding block 1 One end of 211 slides on arc block 2 123, so that arc rod 1 212 gradually moves to a state parallel to sliding plate 122. During the sliding process of arc rod 1 212, it will drive sliding block 213 on the top of arc rod 1 212 to slide synchronously. During the sliding process of the two sliding blocks 213, a pulling force is applied to the arc spring 214 to make it open. At the same time, during the process of the two sliding blocks 213 moving away from each other, the folding ring 221 is squeezed to make it shrink. During the shrinkage of the folding ring 221, the protrusion inside it Part of it will contact the outer surface of the flange neck 111, thereby generating friction when the flange neck 111 rotates, thereby slowing down the speed of the flange neck 111 when rotating. This reduces the situation where the flange is connected to a heavier pipe and used for too long, and the heavier pipe may rotate too fast due to insufficient friction of the flange when rotating, causing wear at the connection between the heavier pipe and the flange and the ratchet structure inside the flange. This ensures the overall quality of the flange and internal structure during operation and effectively reduces the occurrence of accidents.

[0067] When the two sliding blocks 213 push the folding ring 221 to fold, one of the sliding blocks 213 will synchronously push the rotating bar 312 to rotate around the center of the flange neck 111 on the fixed ring 311. During the rotation of the rotating bar 312, it will push several arc rods 213 to slide inside the rectangular groove 222 toward the center of the flange neck 111, thereby squeezing the folding ring 221 so that it can be prevented from rotating itself during the rotation of the flange neck 111 due to the rotation of the flange neck 111. At the same time, during the resetting process, the rotating bar 312 will rotate. The two sliding blocks 213 are both connected to the folding ring 221, so they will pull the folding ring 221 to expand as a whole. When the folding ring 221 expands, the arc rod 2313 on the rotating bar 312 will rotate to assist the folding ring 221 in resetting and prevent it from shifting during the resetting process. The rotation of the rotating bar 312 drives the arc rod 2313 to support the folding ring 221, effectively avoiding the situation where the heavier pipe is rotated due to excessive rotational force and the friction force of the folding ring 221, thereby driving the folding ring 221 to rotate and causing deviation. The heavier pipe is further protected when it is in operation, thereby improving the efficiency of the device during operation.

[0068] When the folding ring 221 is not squeezed by the sliding block 213, the folding ring 221 itself is in an open state. When the folding ring 221 is in this state, its two ends will stretch the whole. During the stretching process, the gap of the wave groove 223 inside the folding ring 221 will become smaller due to the pulling. In the process of the gap of the wave groove 223 becoming smaller, the spring 314 inside it will be squeezed and contracted. Then, when the flange neck 111 rotates and drives the sliding block 213 to squeeze the folding ring 221, the wave groove 223 will be squeezed when the folding ring 221 is folded. The gap of the wave groove 223 becomes larger and the spring 314 is extended. During the extension process of the spring 314, the folding ring 221 in contact with the outer surface of the flange neck 111 is squeezed, thereby increasing the friction between the raised part of the folding ring 221 and the outer surface of the flange neck 111, further slowing down the inertia of the heavier pipe when it rotates through the main body 1, preventing the flange neck 111 from rotating faster due to the excessive weight of the heavier pipe, thereby improving the safety of the heavier pipe when it runs through the device and protecting the overall quality of the heavier pipe during operation.
