Description

Technical Field

[0001] This utility model relates to the field of screw wear-resistant technology, specifically to a rust-proof and wear-resistant screw. Background Technology

[0002] Screws, as fundamental mechanical parts, are widely used in various fields. In industry, from automobile manufacturing and machining to aerospace, almost all mechanical equipment relies on screws to connect and secure components. For example, numerous components inside a car engine are tightly connected by screws, ensuring the engine's stability under high-speed operation and complex conditions. Screws on aerospace vehicles play an extremely critical role, ensuring they remain secure and reliable even in extreme environments to guarantee flight safety. In daily life, screws are ubiquitous in furniture assembly and appliance repair, providing convenience and stability to people's lives.

[0003] Most screws are made of metal, which is very easy to rust in humid, acidic, or alkaline environments. Screws are often exposed to the outdoors, and factors such as rain, moisture in the air, and industrial pollution will accelerate the corrosion of screws. After the screw rusts, the rust will increase the friction between the screw and the nut. Forced disassembly may cause the screw to break, further increasing the difficulty and cost of maintenance. Therefore, a rust-proof and wear-resistant screw is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is as follows: to provide a rust-proof and wear-resistant screw with high practicality, simple operation and simple structure, which solves the problem mentioned in the background art that most screws are made of metal and are very easy to rust in humid, acidic and alkaline and other corrosive environments. Screws are often exposed to the outdoor environment, and factors such as rain, moisture in the air and industrial pollution will accelerate the corrosion of screws. After the screw rusts, the rust will increase the friction between the screw and the nut. Forced disassembly may cause the screw to break, further increasing the difficulty and cost of maintenance.

[0005] The objective of this utility model can be achieved through the following technical solutions: A rust-proof and wear-resistant screw includes a fixing plate, with snap-fit ​​components fixedly connected to both sides of the fixing plate. A protective cover is provided on the top surface of the fixing plate. A screw body is fixedly connected inside the fixing plate, and an oil injection component is provided inside the screw body. Each of the two snap-fit ​​components includes a connecting spring fixedly connected to both sides of the fixing plate. A snap-fit ​​rod is sleeved inside each of the two connecting springs, and a pull plate is fixedly connected to one side of each of the two connecting springs. The oil injection component includes an oil injection pipe disposed inside the screw body. Four oil outlet pipes are fixedly connected to one end of the oil injection pipe, and a sealing cap is threadedly connected to the outside of the oil injection pipe.

[0006] As a further embodiment of this utility model: positioning plates are fixedly connected to both sides of the protective cover, and two sets of insertion interfaces are opened on the outer side of the protective cover. The two sets of snap-fit ​​rods are inserted into the inside of the insertion interfaces. The snap-fit ​​rods serve to fix the protective cover.

[0007] As a further embodiment of this utility model: the top surface of the fixing plate is provided with a storage groove, and the protective cover is inserted into the inside of the storage groove. By setting the protective cover, the contact of external water molecules with the screw body can be reduced, thereby reducing the possibility of corrosion.

[0008] As a further embodiment of this utility model: four sets of oil grooves are provided on the outer side of the screw body, and the four sets of oil outlet pipes are all arranged inside the oil grooves. The oil grooves enable the lubricating oil to flow, thereby lubricating the screw body.

[0009] As a further embodiment of this utility model: a nut is threadedly connected to the outer side of the screw body, and a connector is fixedly connected to the bottom surface of the screw body. The nut serves to fix the screw body in place.

[0010] As a further embodiment of this utility model: the outer side of the screw body is coated with a corrosion-resistant layer, and a sealing gasket is fixedly connected to the bottom surface of the fixing plate. The sealing gasket helps to prevent water molecules from entering the screw body.

[0011] As a further embodiment of this utility model: a handle is fixedly connected to one side of each of the two sets of pull plates, and an anti-slip sleeve is fitted on the outside of each of the two sets of handles. The anti-slip sleeve helps to prevent the user's hand from slipping.

[0012] The beneficial effects of this utility model are: 1. With the snap-fit ​​assembly and protective cover, after the screws are installed, the sealing gasket fits tightly against the wall or other surfaces. Pulling the pull plate moves the snap-fit ​​rod, which is in a stretched state. Insert the protective cover into the storage slot, release the pull plate, and the connecting spring moves the snap-fit ​​rod back to its original position. The snap-fit ​​rod then inserts into the connector, securing the protective cover. The protective cover isolates the screws from the external environment, preventing oxygen and moisture in the air from contacting the screw surface, thus reducing the possibility of rust.

[0013] 2. With the oil injection component in place, after installation, unscrew the sealing cap to open it from the outside of the oil injection pipe, adding lubricating oil into the pipe. The lubricating oil enters the oil groove and lubricates the screw body. After oil injection, unscrew the sealing cap again to seal the oil injection pipe, preventing oil from flowing out. Regularly injecting lubricating oil will form a lubricating film on the thread surface, effectively reducing the coefficient of friction, reducing wear, and extending the screw's service life. It also prevents the metal surface from sticking due to heat and pressure generated by friction between the threads, ensuring normal disassembly and installation. Attached Figure Description

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-4As shown, a rust-proof and wear-resistant screw includes a fixing plate 1. Both sides of the fixing plate 1 are fixedly connected to snap-fit ​​components 2. Through the snap-fit ​​components 2, the screw body 4 can be installed and removed from the protective cover 3 as needed. The top surface of the fixing plate 1 is provided with the protective cover 3. The screw body 4 is fixedly connected inside the fixing plate 1. An oil injection component 5 is provided inside the screw body 4. The oil injection component 5 lubricates the screw body 4, reducing the screw's coefficient of friction. Both sets of snap-fit ​​components 2 include connecting springs 201 fixedly connected to both sides of the fixing plate 1. Both sets of connecting springs 201 have snap-fit ​​rods 202 sleeved inside them. A pull plate 203 is fixedly connected to one side of each set of connecting springs 201. The oil injection component 5 includes an oil injection pipe 501 located inside the screw body 4. One end of the oil injection pipe 501 is fixedly connected to four sets of oil outlet pipes 502. A sealing cap 503 is threadedly connected to the outer side of the oil injection pipe 501. Positioning plates 6 are fixedly connected to both sides of the protective cover 3. Two sets of insertion interfaces 7 are opened on the outer side of the protective cover 3. Two sets of snap-fit ​​rods 202 are inserted into the inside of the insertion interface 7. The snap-fit ​​rods 202 serve to fix the protective cover 3. The top surface of the fixing plate 1 is provided with a storage groove 8, and the protective cover 3 is inserted into the inside of the storage groove 8. The protective cover 3 can reduce the contact of external water molecules with the screw body 4, thereby reducing the possibility of corrosion. Four sets of oil grooves are provided on the outer side of the screw body 4, and four sets of oil outlet pipes 502 are all located inside the oil grooves. The oil grooves allow the lubricating oil to flow, thereby lubricating the screw body 4. The screw body 4 is threaded with a nut 9 on its outer side, and a connector 10 is fixedly connected to the bottom surface of the screw body 4. The nut 9 serves to fix the screw body 4 in place. The outer side of the screw body 4 is coated with a corrosion-resistant layer, and a sealing gasket 11 is fixedly connected to the bottom surface of the fixing plate 1. The sealing gasket 11 prevents water molecules from entering the screw body 4. Each of the two sets of pull plates 203 has a handle 12 fixedly connected to one side. Both sets of handles 12 have anti-slip sleeves on their outer sides. The anti-slip sleeves prevent the user's hands from slipping.

[0019] The above parameters and models can be selected according to actual needs. The working principle of this utility model is as follows: After the screw is installed, the sealing gasket 11 is tightly attached to the wall, etc. Pull the pull plate 203. The movement of the pull plate 203 drives the snap-fit ​​rod 202 to move. At this time, the connecting spring 201 is in a stretched state. The protective cover 3 is inserted into the inside of the storage slot 8. Release the pull plate 203. The connecting spring 201 drives the snap-fit ​​rod 202 to reset. The snap-fit ​​rod 202 is inserted into the inside of the insertion interface 7 to fix the protective cover 3. The protective cover 3 can isolate the screw from the external environment and prevent oxygen and moisture in the air from contacting the screw surface, thereby reducing the possibility of rust. After installation, unscrew the sealing cap 503 from the outside of the oil injection pipe 501 and add lubricating oil into the oil injection pipe 501. The lubricating oil enters the oil groove and lubricates the screw body 4. After the oil injection is completed, unscrew the sealing cap 503 again to seal the oil injection pipe 501 and prevent oil from flowing out of the oil injection pipe 501. Lubricating oil can be injected periodically to form a lubricating film on the thread surface, which effectively reduces the coefficient of friction, reduces wear, and extends the service life of the screw. At the same time, it can also prevent the metal surface from sticking due to the heat and pressure generated by friction between the threads, ensuring normal disassembly and installation.
