Description

Technical Field

[0001] This utility model relates to the field of flange bolt technology, and more specifically, to a structure for preventing the loosening of plum blossom flange bolts. Background Technology

[0002] A plum blossom flange bolt is a type of flange bolt with a special head design. Its head is shaped like a plum blossom, combining the fastening performance of a flange bolt with the unique advantages of a plum blossom head.

[0003] Currently, to improve their anti-loosening performance, capillary flange bolts are equipped with anti-loosening structures. However, common anti-loosening structures have poor anti-loosening effect and are not easy to disassemble later. For example, a capillary flange bolt with anti-loosening technology disclosed in CN216768057U includes a receiving part, an anti-slip part movably disposed on the receiving part, and a locking part threaded on the receiving part. The receiving part includes a screw, the anti-slip part includes a washer sleeved on the screw, and the washer has an engagement plate on the side facing the locking part. The locking part includes a second support plate, the bottom end of the second support plate has an annular engagement tooth, and the annular engagement tooth engages with the engagement plate. Guide grooves are opened on the top of both sides of the outer edge of the screw.

[0004] As can be seen from the above-disclosed scheme, the bolt is engaged with the meshing plate on the washer by the annular meshing teeth on the second support plate to ensure that the bolt does not fall off. When the second support plate and the meshing plate are squeezed against each other, the meshing teeth will be damaged, reducing the meshing firmness. Moreover, the washer can also move axially after engagement. When squeezed, the squeezing force will act on the nut, which will cause the nut to move axially and cause stripping, thereby reducing the bolt's anti-loosening performance. Furthermore, the meshing teeth of the second support plate and the washer will be deformed after engagement, which will make it inconvenient to disassemble the screw later. At the same time, the bolt can only be reused after the parts are replaced. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a structure for preventing the loosening of plum blossom flange bolts. This structure, through the design of an anti-loosening plate, guide groove, locking groove, and locking block, prevents the anti-loosening plate from rotating and moving axially after the compression nut is tightened, greatly improving the anti-loosening effect of the bolt. Furthermore, the elastic plate, when compressed by the compression nut, causes the locking block to insert into the locking groove, and automatically resets after the compression nut is released, thus automatically disengaging the locking block from the locking groove, facilitating subsequent bolt disassembly and improving ease of use.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A type of anti-loosening plum blossom flange bolt structure includes a bolt body, which includes a threaded rod. A nut is fixedly connected to one end of the threaded rod, and a compression nut is threaded onto the surface of the threaded rod. One end of the threaded rod has radially symmetrical guide grooves, and the inner wall of the guide grooves has evenly spaced retaining grooves. An anti-loosening component is slidably connected to the surface of the threaded rod, and a clamping component is movably connected to the inner wall of the anti-loosening component. One end of the clamping component is located within the guide groove. This anti-loosening plum blossom flange bolt structure, through the design of the anti-loosening plate, guide groove, retaining grooves, and retaining block, prevents the anti-loosening plate from rotating and axially moving after the compression nut is tightened, greatly improving the anti-loosening effect of the bolt. Furthermore, the elastic plate, when compressed by the compression nut, causes the retaining block to insert into the retaining groove; after the compression nut is removed, it automatically resets, allowing the retaining block to automatically disengage from the retaining groove, facilitating subsequent bolt disassembly and improving ease of use.

[0008] Furthermore, the anti-detachment component includes an anti-detachment plate with a sliding hole at its center. The inner wall of the sliding hole is slidably connected to the surface of the screw. The inner wall of the sliding hole has radially symmetrical receiving grooves. The sliding hole allows the anti-detachment plate to slide axially on the surface of the screw. At the same time, through the receiving grooves connected to it, one end of the locking block is placed inside the sliding hole, thereby restricting the anti-detachment plate from rotating on the surface of the screw.

[0009] Furthermore, the clamping assembly includes an elastic plate, which is arc-shaped. One end of the elastic plate is fixedly connected to a limiting block, and the other end of the elastic plate is fixedly connected to a clamping block. When the elastic plate is compressed, the clamping block extends out of the receiving groove, thereby clamping the clamping block with the groove.

[0010] Furthermore, the surface of the anti-detachment plate has radially symmetrical limiting grooves. The bottom of the limiting grooves is connected to the receiving groove, and the inner wall of the limiting grooves is movably connected to the surface of the elastic plate. The limiting grooves allow the elastic plate to automatically reset after it is released from the compression of the compression nut, thereby causing the locking block to automatically disengage from the locking groove.

[0011] Furthermore, the surfaces of the card block and the limiting block are slidably connected to the inner wall of the storage groove, one end of the card block is provided with an inclined surface, the surface of the card block is slidably connected to the inner wall of the guide groove, and the inclined surface has a guiding function to facilitate the card block entering the card groove.

[0012] Furthermore, a first washer is movably connected to the surface of the nut, and a spring washer is fixedly connected to the surface of the first washer, which has the function of shock absorption and anti-loosening.

[0013] Furthermore, a second pad is movably connected to one end of the compression nut, and a spring sheet is fixedly connected to the surface of the second pad, which has the function of shock absorption and anti-loosening.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] This solution, through the design of anti-loosening plates, guide grooves, slots, and blocks, ensures that after the nut is tightened, the anti-loosening plate can prevent it from rotating and also prevent it from moving axially, greatly improving the anti-loosening effect of the bolt.

[0016] This solution uses an elastic plate that allows the locking block to insert into the slot when compressed by the nut. After the compression from the nut is released, the locking block automatically resets and disengages from the slot, facilitating subsequent bolt disassembly and improving ease of use.

Detailed Implementation

[0024] 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. Example 1

[0025] Please see Figure 1-5A type of anti-loosening plum blossom flange bolt structure includes a bolt body 1, which includes a bolt 14. One end of the bolt 14 is fixedly connected to a nut 11, which is hexagonal (existing technology). A compression nut 2, also hexagonal, is threaded onto the surface of the bolt 14. One end of the bolt 14 has radially symmetrical guide grooves 15, which restrict the rotation of an anti-loosening plate 31. The inner wall of the guide grooves 15 has evenly spaced slots 16. An anti-loosening component 3 is slidably connected to the surface of the bolt 14. The anti-loosening component 3 includes an anti-loosening plate 31. A sliding hole 34 is formed at the center of the anti-loosening plate 31. The inner wall of the sliding hole 34 is slidably connected to the surface of the bolt 14. The inner wall of the sliding hole 34 has radially symmetrical receiving grooves 32, allowing the anti-loosening plate 31 to... The screw 14 slides axially on its surface, and through the receiving groove 32 connected to it, one end of the locking block 43 is placed in the sliding hole 34, thereby restricting the anti-detachment plate 31 from rotating on the surface of the screw 14. The anti-detachment component 3 can prevent the squeezing force from acting on the surface of the squeezing nut 2 after the bolt is locked. The inner wall of the anti-detachment component 3 is movably connected to the clamping component 4. The clamping component 4 includes an elastic plate 41, which is arc-shaped. One end of the elastic plate 41 is fixedly connected to the limit block 42, and the other end of the elastic plate 41 is fixedly connected to the locking block 43. When the elastic plate 41 is squeezed, the locking block 43 extends out of the receiving groove 32, thereby locking the locking block 43 with the locking groove 16. The clamping component 4 is used to fix the locking position of the anti-detachment component 3. One end of the clamping component 4 is placed in the guide groove 15.

[0026] The surface of the anti-detachment plate 31 has radially symmetrical limiting grooves 33. The bottom of the limiting grooves 33 is connected to the receiving groove 32. The inner wall of the limiting grooves 33 is movably connected to the surface of the elastic plate 41. The limiting grooves 33 allow the elastic plate 41 to automatically reset after it is released from the compression of the compression nut 2, thereby allowing the locking block 43 to automatically disengage from the locking slot 16. The surfaces of the locking block 43 and the limiting block 42 are slidably connected to the inner wall of the receiving groove 32. One end of the locking block 43 is provided with an inclined surface 44. The surface of the locking block 43 is slidably connected to the inner wall of the guide groove 15. The inclined surface 44 has a guiding function, which facilitates the locking block 43 to enter the locking slot 16.

[0027] The surface of the nut 11 is movably connected to the first washer 12, and the surface of the first washer 12 is fixedly connected to the spring washer 13, which has the function of shock absorption and anti-loosening. One end of the compression nut 2 is movably connected to the second washer 21, and the surface of the second washer 21 is fixedly connected to the spring piece, which has the function of shock absorption and anti-loosening.

[0028] When using this anti-loosening plum blossom flange bolt structure, firstly, the first washer plate 12 is placed on the bolt 14. Then, one end of the bolt 14 is passed through the threaded hole of the workpiece, and then the anti-loosening plate 31 is fitted. At this time, one end of the symmetrical locking block 43 is in the two guide grooves 15. Then, the compression nut 2 is tightened clockwise. At this time, the anti-loosening plate 31 contacts the surface of the workpiece, which causes the compression nut 2 to compress the elastic plate 41. The elastic plate 41 is compressed, causing the locking block 43 to extend out of the receiving groove 32. The locking block 43 extending out of the receiving groove 32 allows one end to be inserted into the locking groove 16 at this position, thus preventing loosening. Plate 31 is positioned on the surface of screw 14. At this time, the workpiece is pressed against the anti-detachment plate 31. The pressing force will not act on the pressing nut 2, so that the pressing nut 2 will not slide axially under the action of external force and cause stripping. When it is necessary to disassemble the bolt, the pressing nut 2 can be removed counterclockwise. The pressing nut 2 is disassembled counterclockwise to release it from the pressing of the anti-detachment plate 31 and the elastic plate 41. At this time, the elastic plate 41 is reset, which causes the locking block 43 to retract into the receiving groove 32, so that one end of it is disengaged from the locking groove 16. At this time, the anti-detachment plate 31 can be axially moved and disassembled on the surface of screw 14.

[0029] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
