Abstract
Description
Technical Field
[0001] This application relates to the field of nut technology, specifically stainless steel torsion nuts. Background Technology
[0002] Stainless steel breakaway nuts, as a unique type of fastener, play a crucial role in many fields. Their core advantages lie in their superior anti-theft and fastening performance. Structurally, they are typically composed of an inner sleeve and an outer sleeve. The inner surface of the inner sleeve is threaded for a tight fit with the screw. The outer sleeve uses a common standard nut shape for easy installation. When an external force is applied to the outer sleeve, it drives the inner sleeve to rotate synchronously. The interaction between the inner sleeve and the tightening nut generates tension, achieving initial tightening. As the external force continues to increase, when a specific torque is reached, the outer sleeve separates from the inner sleeve. The outer sleeve enters a free rotation state, while the inner sleeve is firmly fixed to the screw and cannot be tightened again, thus achieving the purpose of preventing removal and theft.
[0003] However, some problems still exist in the current use. The main issue is that the torsion bar stands upright on the nut, which poses many hidden dangers. For example, if it stands horizontally in areas where equipment is running or people are active, it can easily cause leg injuries. Folding the torsion bar when not in use can reduce protruding parts, lower the risk of people tripping or being scratched, improve workplace safety, and greatly reduce the overall space occupied. For the storage and transportation of nuts and other parts, more items can be placed in a limited space, improving space utilization. However, the shock absorption effect on the nut is not good. If multiple protective measures are added, when the nut is subjected to vibration or external force, multiple anti-loosening components will work together to improve the anti-loosening effect. To solve the above problems, a stainless steel torsion nut is proposed. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides a stainless steel torsion nut, which has the advantages of high flexibility of folding torsion bars and excellent shock absorption effect with multiple anti-loosening measures, thus solving the problems mentioned in the background technology.
[0005] To achieve the above objectives, this application provides the following technical solution: a stainless steel torsion nut, comprising a torsion nut body, a torsion mechanism, a first torsion bar, a folding mechanism, a limiting mechanism, a sealing mechanism, and a multiple anti-loosening mechanism. The folding mechanism includes a fixing block fixedly connected to one end of the first torsion bar. There are two fixing blocks, and a pin is provided inside each of the two fixing blocks. A support rod is fixedly connected to the surface of the pin. A second torsion bar is fixedly connected to one end of the support rod. Positioning holes are provided on the surfaces of both the first and second torsion bars. Positioning pins are inserted into the positioning holes. Threaded grooves are provided on the surface of the positioning pins. There are two threaded grooves, and nuts are threadedly connected to the surfaces of both threaded grooves.
[0006] The above solution, by setting up a toggle mechanism, facilitates the operation of the nut, providing a more convenient point of force application. Compared to directly rotating the nut body, using the toggle mechanism allows for more effortless and precise control of the nut's rotation, especially suitable for situations requiring larger torque or where operating space is limited. By incorporating a folding mechanism, the first and second toggle rods can be connected via a fixed block, pin, and support rod, allowing the toggle rods to fold and unfold. This design allows for adjustment of the toggle rod's length and shape according to actual usage needs. When not in use, it folds up for easy storage and reduces space occupation; when in use, it unfolds to obtain sufficient lever arm to rotate the nut, improving operational flexibility and convenience. The limiting mechanism locks the folded second torsion bar, ensuring its stability. The sealing mechanism effectively prevents dust, moisture, and impurities from entering the nut, protecting its threads and other critical parts from corrosion and wear, extending its lifespan, and improving its reliability in harsh environments. Multiple anti-loosening mechanisms enhance the nut's anti-loosening performance, preventing it from loosening under vibration and impact conditions, ensuring connection reliability. The combination of various anti-loosening measures addresses nut loosening from different angles, such as friction-based and mechanical anti-loosening, making it suitable for applications requiring high connection stability.
[0007] Furthermore, the torsion mechanism includes a through hole on the surface of the torsion nut body, and a first torsion bar is fixedly connected inside the through hole.
[0008] The above solution provides an installation point for the first torsion bar by setting a through hole. The first torsion bar, in conjunction with the second torsion bar, allows for a skillful rotation of the torsion nut body.
[0009] Furthermore, the limiting mechanism includes a limiting hole provided on the surface of the second torsion bar, a support block is fixedly connected to the surface of the torsion nut body, and a limiting rod is inserted into the inside of the support block.
[0010] The above scheme provides an insertion point for the limiting rod by setting a limiting hole, a storage point for the limiting rod by setting a support block, and a fixation point for the second torsion bar by setting a limiting rod.
[0011] Furthermore, the sealing mechanism includes an adhesive layer disposed on the top of the torsion nut body, and a sealing ring is overlapped on the top of the adhesive layer.
[0012] The above solution, by setting an adhesive layer, can fix the sealing ring in place, and by setting the sealing ring, can block dust, moisture or impurities.
[0013] Furthermore, the multiple anti-loosening mechanism includes a magnetic layer disposed at the bottom of the torsion nut body, an anti-loosening washer overlapping the bottom of the magnetic layer, an elastic sheet overlapping the bottom of the anti-loosening washer, an elastic washer overlapping the bottom of the elastic sheet, and a fixing box fixedly connected to the bottom of the elastic washer. There are two fixing boxes, and a limit plate is inserted into the interior of each of the two fixing boxes. A limit block is inserted into the interior of the fixing box and the interior of the limit plate. There are two limit blocks, and the anti-loosening washer is made of ferrous material.
[0014] The above solution achieves a tighter fit between the torsion nut body and the anti-loosening washer by setting a magnetic layer. The anti-loosening washer, elastic sheet, and elastic washer, along with the limiting plate, provide multiple shock absorption for the torsion nut body. The fixing box provides a storage space for the limiting plate, and the limiting block locks the limiting plate in place.
[0015] Furthermore, an LED light and a button are fixedly mounted on the surface of the first torsion bar.
[0016] The above solution, by setting LED lights and buttons, can provide illumination to dark areas.
[0017] Furthermore, a miniature gravity sensor is installed inside the torsion nut body, and an audible light is fixedly installed on the surface of the torsion nut body.
[0018] The above solution, by setting up a gravity sensor and an audible light, can transmit data on the falling of the broken nut and use the audible light to alert the user, making it easier to quickly locate the falling position and improving search efficiency.
[0019] Furthermore, dustproof boxes are fixedly connected to the surfaces of both fixed blocks, and cover plates are movably connected to the surfaces of both dustproof boxes via hinges. Magnetic blocks are provided on the sides of both the dustproof boxes and the cover plates, and there are four sets of magnetic blocks.
[0020] The above solution, by setting up a dustproof box and cover, can effectively block external dust from the area of the pin shaft after oiling, and by setting up a magnet, can lock the cover.
[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0022] This stainless steel torsion nut features a torsion-shifting mechanism, facilitating easy operation and providing a more convenient point of force application. Compared to directly rotating the nut body, the torsion-shifting mechanism allows for more effortless and precise control of the nut's rotation, making it particularly suitable for situations requiring higher torque or where operating space is limited. A folding mechanism connects the first and second torsion bars via a fixed block, pin, and support rod, allowing the torsion bars to be folded and unfolded. This design allows for adjustment of the torsion bar's length and shape according to actual usage needs. When not in use, it folds up for easy storage and reduces space occupation; when in use, it unfolds to obtain sufficient lever arm to rotate the nut, improving operational flexibility and convenience. By setting a limiting mechanism, the second torsion bar after folding can be locked, ensuring its stability. By setting a sealing mechanism, dust, moisture, impurities, etc. can be effectively prevented from entering the nut, protecting the nut's threads and other critical parts from corrosion and wear, extending the nut's service life, and improving its reliability in harsh environments. By setting multiple anti-loosening mechanisms, the nut's anti-loosening performance is enhanced, preventing the nut from loosening under vibration, impact, and other conditions, ensuring the reliability of the connection. The combined use of multiple anti-loosening measures can solve the problem of nut loosening from different angles, such as friction anti-loosening and mechanical anti-loosening, which is suitable for occasions with high requirements for connection stability.

A second torsion bar 304 is fixedly connected to one end of the support rod 303. The surface of the first torsion bar 202 and the second torsion bar 304 are connected to each other. The surface of 04 is provided with positioning holes 305. Positioning pins 306 are inserted into the positioning holes 305. The surface of the positioning pins 306 is provided with threaded grooves 307. There are two threaded grooves 307. Nuts 308 are threadedly connected to the surfaces of the two threaded grooves 307.

[0035] Please see Figure 1 , Figure 4 , Figure 5 and Figure 6The sealing mechanism 5 includes an adhesive layer 501 disposed on the top of the torsion nut body 1, with a sealing ring 502 overlapping the top of the adhesive layer 501. The adhesive layer 501 secures the sealing ring 502 and provides a barrier against dust, moisture, or impurities. The combination of the adhesive layer 501 and the sealing ring 502 effectively blocks external dust, moisture, or impurities. The multiple anti-loosening mechanism 6 includes a magnetic layer 601 disposed at the bottom of the torsion nut body 1, with an anti-loosening washer 602 overlapping the bottom of the magnetic layer 601. An elastic sheet 603 overlaps the bottom of the anti-loosening washer 602, and an elastic washer 604 overlaps the bottom of the elastic sheet 603. Two fixing boxes 605 are fixedly connected to the bottom of each fixing box 605, and each fixing box 605 has a limit plate 606 inserted inside. Two limit blocks 607 are inserted into the interior of the limiting plate 606. The anti-loosening washer 602 is made of iron. By setting a magnetic layer 601, the broken nut body 1 can be more tightly fitted with the anti-loosening washer 602. By setting the anti-loosening washer 602, elastic sheet 603 and elastic washer 604, and working with the limiting plate 606, the broken nut body 1 is provided with multiple shock absorption effects. By setting a fixing box 605, the limiting plate 606 can be provided with a storage position. By setting the limit blocks 607, the limiting plate 606 can be locked. By setting the anti-loosening washer 602, elastic sheet 603 and elastic washer 604, the limiting plate 606 is inserted into the external threaded post groove, and then the limit blocks 607 are inserted into the fixing box 605 and the limiting plate 606, thereby achieving the purpose of anti-loosening and shock absorption of the broken nut body 1.
[0036] Please see Figure 1 and Figure 3 An LED light 7 and a button 8 are fixedly installed on the surface of the first torsion bar 202. The LED light 7 and the button 8 can provide illumination for dark areas. A miniature gravity sensor 9 is installed inside the broken nut body 1. A sound light 10 is fixedly installed on the surface of the broken nut body 1. The gravity sensor and the sound light 10 can transmit data on the falling of the broken nut body 1 and make a sound call out through the sound light 10, which can facilitate quick location of the falling position and improve search efficiency. Dustproof boxes 11 are fixedly connected to the surfaces of the two fixing blocks 301. The surfaces of the two dustproof boxes 11 are movably connected to the cover plates 12 through hinges. Magnetic blocks 13 are provided on the sides of the dustproof boxes 11 and the sides of the cover plates 12. There are four sets of magnetic blocks 13. By setting the dustproof boxes 11 and the cover plates 12, the area of the pin 302 after being coated with oil can be blocked from external dust. The cover plates 12 can be locked by setting the magnets.
[0037] In this embodiment, the stainless steel torsion nut utilizes the rotation of the pin 302 to fold the second torsion bar 304. This aligns with the insertion of the positioning pin 306 into the positioning hole 305, and the screw nut 308 into the threaded groove 307, thereby locking the first torsion bar 202 and the second torsion bar 304. By manipulating the first torsion bar 202 and the second torsion bar 304, the torsion nut body 1 can be installed with minimal effort. The limiting rod 403 further restricts the movement of the second torsion bar 304. The fixed effect is achieved by inserting the limiting rod 403 through the support block 402 into the limiting hole 401, thereby locking the folded second torsion bar 304. The adhesive layer 501 and the sealing ring 502 are used to block external dust, moisture or impurities. The anti-loosening washer 602, elastic sheet 603 and elastic washer 604 are used to insert the limiting plate 606 into the external threaded post groove, and then the limiting block 607 is inserted into the fixing box 605 and the limiting plate 606, thereby achieving the purpose of preventing loosening and shock absorption of the torsion nut body 1.
[0038] The working principle of the above embodiment is as follows: First, by utilizing the rotational characteristics of the pin 302, the second torsion bar 304 is erected. Then, the positioning pin 306 is inserted into the positioning hole 305, and the nut 308 is screwed into the threaded groove 307, thereby locking the second torsion bar 304. Then, the torsion nut body 1 is positioned at the external threaded post. After that, the second torsion bar 304 is moved, thereby installing the torsion nut body 1 on the external threaded post. After installation, the anti-loosening washer 602, the elastic plate 603, and the elastic washer 604 are all installed at the bottom of the torsion nut body 1. Then, the limiting plate 606 is inserted through the fixing box 605 into the threaded groove of the external threaded post. Then, the limiting block 607 is inserted into the fixing box 605 and the limiting plate 606, thereby locking the limiting plate 606. Subsequently, the anti-loosening washer 602, the elastic plate 603, and the elastic washer 604 can be used to perform multiple locking and locking of the torsion nut body 1. After the anti-loosening and shock absorption are completed, the positioning pin 306 can be removed, then the second torsion bar 304 can be folded, and the limiting rod 403 can be inserted through the support block 402 into the limiting hole 401 to lock the second torsion bar 304. If there is external dust, moisture or impurities during use, the sealing ring 502 can be used to cover the inside of the broken nut body 1. If the installation area is particularly dark when installing the broken nut body 1, the button 8 can be pressed to illuminate the dark area with the LED light 7, which will facilitate subsequent work. At the same time, if the broken nut body 1 is accidentally dropped on the ground, the micro gravity sensor 9 and the sound light 10 can be activated to transmit the signal of the drop to the sound light 10, which will then make a sound for personnel to quickly locate it. Finally, when the pin 302 needs to be filled with oil, the dust box 11 and the cover plate 12 can be used to cover the external dust.
