Description

Technical Field

[0001] This utility model relates to the field of spring-loaded nut technology, and in particular to a quick-assembly and disassembly structure for multi-stage spring-loaded shock-absorbing nuts. Background Technology

[0002] As modern industry develops towards higher precision and stability, vibration problems during the operation of mechanical equipment are becoming increasingly prominent. This not only affects the service life and accuracy of equipment but also poses safety hazards. In this context, multi-stage spring-loaded vibration damping nuts have emerged. With their unique structural design and damping principle, they have become key components for solving vibration problems and are widely used in many fields such as automobiles, aerospace, and industrial machinery, providing reliable assurance for the stable operation of equipment.

[0003] Spring-loaded vibration damping nuts typically consist of a nut body and elastic spring plates. These nuts utilize the elastic deformation of the spring plates to absorb and buffer vibration energy. When the nut is subjected to vibration, the spring plates deform, using elastic force to offset some of the impact force, thereby reducing the impact of vibration on the connected components. This provides damping and anti-loosening protection, ensuring the stability and reliability of the connection.

[0004] In existing technologies, some spring-loaded shock-absorbing nuts are difficult to install quickly in practical applications. Some nuts require a lot of time to adjust the spring position and ensure installation accuracy during installation, which increases the workload of installers and seriously reduces the installation speed of nuts. To solve the above problems, a multi-stage spring-loaded shock-absorbing nut quick-disassembly and assembly structure is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a quick-assembly and disassembly structure for multi-stage spring-loaded shock-absorbing nuts, aiming to improve the problem that some spring-loaded shock-absorbing nuts in the prior art cannot be quickly installed and disassembled.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The multi-stage spring-loaded shock-absorbing nut quick-release structure includes a nut body, a plate groove that is slidably connected to the outside of the nut body, a disassembly and assembly mechanism inside the nut body, and a positioning mechanism that is fixedly connected to the outside of the nut body.

[0008] The disassembly and assembly mechanism includes a conical plate, the outer side of which is slidably connected to the inside of the nut body. The inside of the nut body is slidably connected to two limiting slide plates. An oblique round rod is fixedly connected to the outer side of each of the two limiting slide plates. The outer sides of the two oblique round rods are slidably connected to the outer surface of the conical plate. A pushing component is provided at the top of the conical plate. A return spring is fixedly connected between the outer sides of the two limiting slide plates.

[0009] As a further description of the above technical solution:

[0010] The positioning mechanism includes a fixed frame, with one outer side of the fixed frame fixedly connected to the outside of the nut body. A pull plate is slidably connected inside the fixed frame, and a connecting long plate is fixedly connected to the bottom of the pull plate. The outer side of the connecting long plate contacts the outer surface of the plate groove. An elastic component is provided inside the fixed frame.

[0011] As a further description of the above technical solution:

[0012] The pushing assembly includes a threaded sleeve, the outside of which is fixedly connected to the inside of the nut body, and a rotating bolt is threadedly connected to the inside of the threaded sleeve, the bottom of which contacts the top of the tapered plate.

[0013] As a further description of the above technical solution:

[0014] The elastic component includes a guide rod, which is externally fixedly connected to the inside of the fixed frame. A limiting spring is sleeved on the outside of the guide rod, and the inside of the pull plate is slidably connected to the outside of the guide rod.

[0015] As a further description of the above technical solution:

[0016] One outer end of the limiting spring is fixedly connected to the inner wall of the fixed frame, and the other outer end of the limiting spring is fixedly connected to the outer side of the pull plate.

[0017] As a further description of the above technical solution:

[0018] An inner spring sheet is fixedly connected to the bottom of the nut body, and an outer spring sheet is fixedly connected to the bottom of the nut body.

[0019] As a further description of the above technical solution:

[0020] The inner spring is disposed on the top of the outer spring, and the nut body has a threaded connection hole on its inner top side;

[0021] As a further description of the above technical solution:

[0022] The bottom of the outer spring sheet is slidably connected to the inner bottom side of the plate groove, and the outer sides of the two limiting slide plates are slidably connected to the inner groove of the plate groove.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, by rotating the rotating bolt, the rotating bolt rotates inside the threaded sleeve, thereby pushing the conical plate. The conical plate pushes the limiting slide plate through the inclined round rod. At the same time, the return spring is stretched, causing the limiting slide plate to slide into the groove and lock. By rotating the rotating bolt in the opposite direction, the return spring causes the limiting slide plate to exit the groove, achieving the effect of quick nut disassembly and assembly. The operation is simple and can quickly complete the installation and disassembly.

[0025] 2. In this utility model, pulling the pull plate compresses the limiting spring, inserts the nut body into the plate groove, and then releases the pull plate. The limiting spring pushes the pull plate to press the connecting long plate into the plate groove for positioning, thus achieving the effect of fixing the nut's position in the plate groove. The advantage is that the nut can be positioned quickly, ensuring the stability of the nut during operation, preventing the nut from shaking in the plate groove, and enhancing the reliability of the overall structure.

[0032] 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.

[0033] Reference Figures 1 to 3The present invention provides an embodiment of a multi-stage spring-loaded shock-absorbing nut quick-disassembly and assembly structure, comprising a nut body 1, which is the core load-bearing component of the entire structure and has sufficient strength and wear resistance. The nut body 1 is externally slidably connected to a plate groove 2, which is installed on the frame or workbench of the mechanical equipment as the mounting base of the nut body 1. The nut body 1 is internally provided with a disassembly and assembly mechanism, and the nut body 1 is externally fixedly connected to a positioning mechanism.

[0034] The disassembly and assembly mechanism includes a conical plate 3, which slides up and down inside the nut body 1 and is a key moving part for realizing the disassembly and assembly function. The outside of the conical plate 3 is slidably connected to the inside of the nut body 1. The inside of the nut body 1 is slidably connected to two limiting slide plates 4. The two limiting slide plates 4 are symmetrically arranged inside the nut body 1 and play the role of limiting the position. The outer sides of the two limiting slide plates 4 are fixedly connected to a beveled round rod 5. The beveled round rod 5 can move along the conical surface when the conical plate 3 slides, thereby driving the limiting slide plates 4 to move. The outside of the two beveled round rods 5 are slidably connected to the outer surface of the conical plate 3. The top of the conical plate 3 is provided with a pushing component. The outside of the two limiting slide plates 4 is fixedly connected to a return spring 6. The return spring 6 can restore the limiting slide plates 4 to the initial position.

[0035] The pushing component includes a threaded sleeve 7, which matches the nut body 1 and has a high internal thread precision to ensure smooth engagement with the rotating bolt 8. The threaded sleeve 7 is externally fixedly connected to the inside of the nut body 1, and the rotating bolt 8 is internally threadedly connected to the threaded sleeve 7. By rotating the rotating bolt 8, it moves up and down inside the threaded sleeve 7, thereby pushing the conical plate 3 to move and realizing the disassembly and assembly function. The bottom of the rotating bolt 8 contacts the top of the conical plate 3.

[0036] Reference Figure 1 and Figure 4 The positioning mechanism includes a fixed frame 9, which serves as the basic load-bearing structure of the positioning mechanism and has a certain strength and rigidity. The outer side of the fixed frame 9 is fixedly connected to the outside of the nut body 1. The inside of the fixed frame 9 is slidably connected to a pull plate 12. The pull plate 12 drives the connecting long plate 13 to contact the plate groove 2, thereby realizing the positioning function of the nut body. The bottom of the pull plate 12 is fixedly connected to the connecting long plate 13. One end of the connecting long plate 13 is fixedly connected to the pull plate 12, and the other end contacts the surface of the plate groove 2, which can keep the position of the nut body 1 stable. The outer side of the connecting long plate 13 contacts the outer surface of the plate groove 2. The fixed frame 9 is equipped with an elastic component inside.

[0037] The elastic component includes a guide rod 10, which provides precise guidance for the sliding of the pull plate 12 and protects the limiting spring 11. The guide rod 10 is externally fixedly connected to the inside of the fixed frame 9, and the limiting spring 11 is sleeved on the outside of the guide rod 10. The limiting spring 11 provides elastic force to the pull plate 12, and the pull plate 12 keeps the connecting long plate 13 in contact with the plate groove 2 to achieve the positioning of the nut body 1. The inside of the pull plate 12 is slidably connected to the outside of the guide rod 10. One end of the limiting spring 11 is fixedly connected to the inner wall of the fixed frame 9, and the other end of the limiting spring 11 is fixedly connected to the outer side of the pull plate 12.

[0038] Reference Figure 1 and Figure 2 The bottom of the nut body 1 is fixedly connected to an inner spring sheet 14. When the inner spring sheet 14 is subjected to vibration, it can absorb part of the vibration energy through its own elastic deformation. The bottom of the nut body 1 is fixedly connected to an outer spring sheet 15. The outer spring sheet 15 plays the role of protecting the inner spring sheet 14 and further damping the vibration. The outer side of the inner spring sheet 14 is set on the top of the outer spring sheet 15. The top side of the nut body 1 is provided with a threaded connection hole 16. The threaded connection hole 16 is used to connect the components installed on the nut body 1. The bottom of the outer spring sheet 15 is slidably connected to the bottom side of the inner side of the plate groove 2. The outer sides of the two limiting slide plates 4 are slidably connected to the inner groove of the plate groove 2.

[0039] Working principle: During installation, first pull the pull plate 12. The pull plate 12 causes the connecting long plate 13 to slide on the guide rod 10. At the same time, the pull plate 12 compresses the limit spring 11. After inserting the nut body 1 into the plate groove 2, the pull plate 12 is released. The limit spring 11 restores its deformation and generates elastic force. The elastic force pushes the pull plate 12 to press the connecting long plate 13 into the plate groove 2 for positioning.

[0040] Rotate the rotating bolt 8. The rotating bolt 8 moves downward by rotating in the threaded sleeve 7. The downward movement of the rotating bolt 8 can push the conical plate 3 to slide downward. The conical plate 3 forces the oblique round rod 5 to slide outward along the conical surface. The oblique round rod 5 pushes the limiting slide plate 4 into the groove of the plate groove 2 for locking. At the same time, the return spring 6 is stretched. When subjected to vibration, the outer spring piece 15 contacts the bottom side of the plate groove 2 and elastically deforms to buffer the vibration. The remaining energy is absorbed by the inner spring piece 14 to achieve two-stage vibration reduction. When disassembling, rotate the rotating bolt 8 in the opposite direction. The return spring 6 restores its deformation and generates elastic force. The elastic force pulls the limiting slide plate 4 to reset and exit the groove to release the lock. Then pull the pull plate 12 to make the connecting long plate 13 disengage from the plate groove 2. Finally, slide the nut body 1 out along the plate groove 2.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
