Description

Technical Field

[0001] This utility model relates to the field of corrosion-resistant screws, specifically a deep-sea pressure-resistant and corrosion-resistant screw. Background Technology

[0002] Screws are structures used to connect two workpieces using threads. To facilitate their use in deep-sea equipment, corrosion-resistant screws are required. The "Anti-corrosion Screw" disclosed in application number "202120878322.1" represents an increasingly mature technology. Its "nut is made of corrosion-resistant plastic material. The nut is fitted onto the screw rod. By unscrewing the top cap of the nut, the bolt can be easily used while protecting the screw head from corrosion. Simultaneously, by applying an anti-corrosion coating to the screw rod, corrosion of the threads on the screw surface is prevented, greatly extending the screw's service life." However, this anti-corrosion screw has the following drawbacks during use: While the plastic nut does provide corrosion protection for the screw head, the anti-corrosion effect achieved solely through this structure is not significant. Furthermore, the overall pressure resistance of the plastic screw needs improvement. Therefore, it is necessary to provide a screw that significantly improves pressure resistance and corrosion resistance, enhancing practicality. Additionally, this anti-corrosion screw is inconvenient to disassemble and assemble as needed. Therefore, it is necessary to provide an anti-corrosion screw that facilitates quick disassembly and assembly, improving ease of use. Utility Model Content

[0003] This invention provides a deep-sea pressure-resistant and corrosion-resistant screw, aiming to solve the problem that the existing corrosion-resistant screws do not have sufficient corrosion resistance and pressure resistance.

[0004] To achieve the above objectives, this utility model provides a deep-sea pressure-resistant and corrosion-resistant screw, including a screw assembly;

[0005] The screw assembly includes a screw body, a pressure-resistant rod fixedly connected to the upper end of the screw body, and connecting holes at the upper ends of both the screw body and the pressure-resistant rod. A tapered hole is formed at the lower end of the screw body, and a reinforcing rod is formed at the lower end of the connecting hole. A tapered head is detachably installed at the lower end of the reinforcing rod and is installed inside the tapered hole. A nut head is fixedly connected to the upper end of the reinforcing rod, and a hexagonal groove is formed at the upper end of the nut head. Several reinforcing strips are fixedly connected to the side surface of the pressure-resistant rod.

[0006] As a preferred embodiment of this utility model, the surfaces of both the screw body and the pressure-resistant rod are electroplated with galvanized steel.

[0007] As a preferred embodiment of this utility model, the inner wall of the connecting hole is provided with a plurality of strip grooves, and the side surface of the reinforcing rod is fixedly connected with a plurality of limiting strips, and the plurality of limiting strips are all engaged inside the strip grooves.

[0008] As a preferred embodiment of this utility model, the upper end of the pressure-resistant rod is fixedly connected with several arc-shaped pieces, and the lower end of the nut head is provided with several arc-shaped grooves, with several arc-shaped pieces being engaged inside the arc-shaped grooves.

[0009] As a preferred embodiment of this utility model, the lower end of the reinforcing rod is provided with a screw hole, and the upper end of the conical head is fixedly connected with a bolt, the bolt being threaded into the inside of the screw hole.

[0010] In a preferred embodiment of this utility model, the screw body, pressure-resistant rod, reinforcing rod, and conical head are all made of stainless steel.

[0011] In a preferred embodiment of this utility model, the cross-section of the limiting strip is triangular.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. When using the screw, the screw body is first threaded into the deep-sea equipment. At this time, the stainless steel screw body, pressure-resistant rod, reinforcing rod, and tapered head can initially provide corrosion and rust prevention and enhance its pressure resistance. Meanwhile, the reinforcing strip on the side surface of the pressure-resistant rod can further enhance the pressure resistance of the anti-corrosion screw. At the same time, the screw body and pressure-resistant rod are electroplated with galvanized steel to isolate them from the strong alkalinity in the deep sea. Compared with the anti-corrosion screw in the existing technology "An Anti-corrosion Screw", this utility model can significantly enhance the pressure resistance and anti-corrosion effect of the anti-corrosion screw through the above-mentioned structure, thereby enhancing the practicality of the anti-corrosion screw.

[0014] 2. When disassembling the anti-corrosion screw, simply remove the bolt from the screw hole to disassemble the tapered head and reinforcing rod. Then, pull the reinforcing rod out of the connecting hole to disassemble the nut head and other structures.

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.

[0022] Example 1

[0023] Please see Figures 1-5 This utility model provides a deep-sea pressure-resistant and corrosion-resistant screw, including a screw assembly 100;

[0024] The screw assembly 100 includes a screw body 101, with a pressure-resistant rod 102 fixedly connected to the upper end of the screw body 101. Both the upper ends of the screw body 101 and the pressure-resistant rod 102 are provided with connecting holes 103. The lower end of the screw body 101 is provided with a tapered hole 104. The lower end of the connecting hole 103 is provided with a reinforcing rod 105. A tapered head 106 is detachably installed at the lower end of the reinforcing rod 105. The tapered head 106 is installed inside the tapered hole 104. A nut head 107 is fixedly connected to the upper end of the reinforcing rod 105. A hexagonal groove 108 is provided at the upper end of the nut head 107. Several reinforcing strips 109 are fixedly connected to the side surface of the pressure-resistant rod 102.

[0025] In one specific embodiment, the screw assembly 100 not only significantly enhances the screw's corrosion resistance and pressure resistance, preventing seawater from corroding the screw and thus enhancing its practicality, but also facilitates quick assembly and disassembly of the various components of the corrosion-resistant screw through the cooperation of the above structures, thereby improving ease of use. In use, the screw body 101 is first threaded into the deep-sea equipment. The stainless steel screw body 101, pressure-resistant rod 102, reinforcing rod 105, and tapered head 106 provide initial corrosion and rust prevention, while also enhancing its pressure resistance. The reinforcing strip 109 on the side surface of the pressure-resistant rod 102 further enhances the pressure resistance of the corrosion-resistant screw. Subsequently, the screw body 101 and the pressure-resistant rod 102 are electroplated with galvanized steel, thus isolating them from the strong alkalinity of the deep sea, significantly enhancing the pressure resistance and corrosion resistance of the screw body 101, and thus enhancing the practicality of the corrosion-resistant screw.

[0026] Please see Figures 2-5 The surfaces of the screw body 101 and the pressure rod 102 are both electroplated with galvanized steel.

[0027] In one specific embodiment, by electroplating galvanized steel, the screw body 101 and the pressure-resistant rod 102 can significantly enhance the corrosion resistance of alkaline seawater, thus enhancing the practicality of the corrosion-resistant screw.

[0028] Please see Figures 2-5 The inner wall of the connecting hole 103 is provided with several strip grooves 111, and several limiting strips 112 are fixedly connected to the side surface of the reinforcing rod 105. The limiting strips 112 are all engaged inside the strip grooves 111.

[0029] In one specific embodiment, by snapping the limiting strip 112 into the inside of the strip groove 111, the connection strength between the reinforcing rod 105, the screw body 101, and the pressure-resistant rod 102 can be enhanced, thereby improving the safety of the screw in use.

[0030] Please see Figures 2-5 The upper end of the pressure-resistant rod 102 is fixedly connected with several arc-shaped pieces 121, and the lower end of the nut head 107 is provided with several arc-shaped grooves 122, and the several arc-shaped pieces 121 are all engaged inside the arc-shaped grooves 122.

[0031] In one specific embodiment, the arc-shaped piece 121 is snapped into the arc-shaped groove 122, thereby further enhancing the connection strength between the pressure-resistant rod 102 and the nut head 107.

[0032] Please see Figures 2-5 The lower end of the reinforcing rod 105 is provided with a screw hole 131, and the upper end of the tapered head 106 is fixedly connected with a bolt 132, which is threaded into the screw hole 131.

[0033] In one specific embodiment, the bolt 132 is threaded into the screw hole 131 to enhance the connection strength between the tapered head 106 and the reinforcing rod 105. The tapered head 106 can be disassembled by removing the bolt 132 from the screw hole 131, and the reinforcing rod 105 can then be disassembled.

[0034] Please see Figures 2-5 The screw body 101, pressure-resistant rod 102, reinforcing rod 105, and tapered head 106 are all made of stainless steel.

[0035] In one specific embodiment, the screw body 101, pressure-resistant rod 102, reinforcing rod 105, and tapered head 106, all made of stainless steel, can prevent rust and significantly enhance pressure resistance, thereby extending the screw's service life.

[0036] Please see Figures 2-5 The cross-section of the limiting strip 112 is triangular.

[0037] In one specific embodiment, the triangular limiting strip 112 can help enhance the compressive strength of the reinforcing rod 105 and the screw body 101, thereby extending the service life of the screw.

[0038] Working principle: In use, the screw body 101 is first threaded into the deep-sea equipment. The stainless steel screw body 101, pressure-resistant rod 102, reinforcing rod 105, and tapered head 106 not only provide corrosion and rust prevention but also enhance its pressure resistance. Meanwhile, the reinforcing strip 109 on the side surface of the pressure-resistant rod 102 further enhances the pressure resistance of the anti-corrosion screw. Then, the screw body 101 and pressure-resistant rod 102 are electroplated with galvanized steel to isolate them from the strong alkalinity of the deep sea, thereby significantly enhancing the pressure resistance and corrosion resistance of the screw body 101, thus improving the practicality of the anti-corrosion screw.
