Description

Technical Field

[0001] This utility model relates to the field of nut technology, and in particular to a novel nut. Background Technology

[0002] A nut is a fastener that is screwed onto a bolt or threaded rod to secure the machine. It is an essential component in all manufacturing machinery. Depending on the material, nuts are classified into several types, such as carbon steel, stainless steel, and non-ferrous metals (e.g., copper). Nuts are used to tightly connect mechanical equipment. Only nuts and bolts of the same specifications can be connected together through their internal threads.

[0003] During use, nuts are threaded together with screws or studs to fix their position. After connection, the connection between the nut and the bolt is exposed to the outside. During frequent use, the end of the nut comes into contact with many impurities, or unknown liquids or solids, which causes severe corrosion of the end, affecting subsequent disassembly. At the same time, the contact of the end with many impurities accelerates the corrosion rate. Therefore, a new type of nut is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a novel nut to solve the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A novel nut includes a nut body with an internal threaded groove and a side connecting slot at one end. An annular protective cover is mounted on the side connecting slot via a rotary connecting assembly. An end arc-shaped cover is provided at the end of the annular protective cover. A side sealing assembly is provided between the annular protective cover and the nut body, and a contact sealing assembly is provided at the end of the nut body.

[0006] Preferably, the rotary connection assembly includes a connecting screw groove formed on the side connecting slot, and a connecting thread is formed on the inner wall of the annular protective cover, with the connecting thread threaded onto the connecting screw groove.

[0007] Preferably, the side sealing assembly includes a side sealing ring disposed on the side of the annular protective cover, and the side sealing ring is in contact with the side connecting groove.

[0008] Preferably, the annular protective cover has a side annular groove, and a side annular block is fixedly installed on the side of the side sealing ring, with the side annular block being movably installed in the side annular groove.

[0009] Preferably, the contact sealing assembly includes a contact sealing ring disposed at the end of the nut body.

[0010] Preferably, the end of the nut body is provided with a contact annular groove, and a contact annular block is fixedly installed on the side of the contact sealing ring, and the contact annular block is movably installed in the contact annular groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the new nut, with its annular protective cover and end arc cover, can achieve end protection, externally blocking the nut body and stud, preventing external interference, and forming a sealed protection to prevent corrosion between the nut body and the connected stud, thus increasing its service life. The side sealing component prevents liquid from seeping in after connection. The contact sealing component is designed with a contact sealing ring on the other side of the nut body. After the nut body is installed, a certain sealing effect can be achieved from both ends, ensuring the sealing of both ends of the nut body and preventing rust damage. Attached Figure Description

[0014] 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.

[0015] Example: Refer to Figure 1-4A novel nut includes a nut body 1 with an internal threaded groove 2 and a side connecting groove 3 at one end. An annular protective cover 5 is mounted on the side connecting groove 3 via a rotary connecting assembly. An end arc-shaped cover 6 is provided at the end of the annular protective cover 5. The annular protective cover 5 is connected to the side connecting groove 3, and the end arc-shaped cover 6 on the annular protective cover 5 provides end protection after the nut body 1 is installed. It blocks the external environment of the nut body 1 and the stud, preventing external interference. By forming a seal, it prevents corrosion between the nut body 1 and the connected stud, increasing their service life. A side sealing assembly is provided between the annular protective cover 5 and the nut body 1, and a contact sealing assembly is provided at the end of the nut body 1.

[0016] Specifically, the rotary connection assembly includes a connecting screw groove 4 opened on the side connection slot 3, and a connecting thread 7 opened on the inner wall of the annular protective cover 5. The connecting thread 7 is threaded onto the connecting screw groove 4. The side sealing assembly includes a side sealing ring 10 set on the side of the annular protective cover 5. The side sealing ring 10 is in contact with the side connection slot 3. A side annular groove 8 is opened on the side of the annular protective cover 5. A side annular block 9 is fixedly installed on the side of the side sealing ring 10. The side annular block 9 is movably installed in the side annular groove 8. The side sealing ring 10 forms a seal between the annular protective cover 5 and the side connection slot 3, making it difficult for liquid to seep in after connection. The connecting screw groove 4 and the connecting thread 7 enable the annular protective cover 5 to be stably connected in the side connection slot 3. The width of the annular protective cover 5 and the end arc-shaped cover 6 is relatively narrow and always located in the side connection slot 3, so as not to affect the installation and disassembly of the nut body 1.

[0017] Specifically, the contact sealing assembly includes a contact sealing ring 13 disposed at the end of the nut body 1. A contact annular groove 11 is provided at the end of the nut body 1. A contact annular block 12 is fixedly installed on the side of the contact sealing ring 13. The contact annular block 12 is movably installed in the contact annular groove 11. A contact sealing ring 13 is also provided on the other side of the nut body 1. After the nut body 1 is installed, a certain sealing effect can be achieved from both ends, ensuring the sealing of both ends of the nut body 1 and preventing rust damage.

[0018] In use: An annular protective cover 5 and an end arc-shaped cover 6 are connected to the side connecting groove 3. After the nut body 1 is installed, it can protect the end and block the external parts of the nut body 1 and the stud, preventing external interference. By forming a seal, it can prevent corrosion between the nut body 1 and the connected stud, thus increasing its service life. The side sealing ring 10 forms a seal between the annular protective cover 5 and the side connecting groove 3, making it difficult for liquid to seep in after connection. The connecting screw groove 4 and connecting thread 7 can make the annular protective cover 5 stably connected in the side connecting groove 3. A contact sealing ring 13 is also provided on the other side of the nut body 1. After the nut body 1 is installed, a certain sealing effect can be achieved from both ends, ensuring the sealing of both ends of the nut body 1 and preventing corrosion damage. It is convenient to use.
