Description

Technical Field

[0001] This utility model relates to the field of mechanical parts technology, and more specifically, to a threaded sleeve made of a special material. Background Technology

[0002] In the field of mechanical connections, threaded sleeves are widely used as an important auxiliary connection component in the assembly of various equipment and structures.

[0003] Based on the above, the inventors have discovered that ordinary threaded sleeves tightly connect mechanical parts through internal threads and are easy to disassemble when used alone. However, some mechanical parts need to function as nuts, but due to the special materials, it is impossible to tap the threads on the parts themselves. Therefore, nuts need to be embedded within the mechanical parts, but the manufacturing process cannot embed the nuts through injection molding, which fails to meet the usage requirements. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a threaded sleeve made of a special material, aiming to achieve a more practical purpose. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a special material threaded sleeve that can achieve a stable connection with special material parts through its own structural design and provide a reliable internal thread connection function. This effectively solves the problem that some mechanical parts are made of special materials that cannot be directly tapped, and the process makes it difficult to embed the nut by injection molding. In such cases, the parts cannot have a built-in nut to achieve the nut function.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A special material threaded sleeve includes a threaded sleeve body, a nut integrally formed on the top of the threaded sleeve body, a self-tapping thread on the outer side of the threaded sleeve body, a nut fixedly connected to the inner side of the threaded sleeve body, a plurality of anti-slip grooves on the self-tapping thread, and a plum blossom groove on the top of the nut.

[0009] Furthermore, the angle of the self-tapping thread is 20-30 degrees.

[0010] Furthermore, the nut has a threaded hole, and the inner side of the threaded hole is provided with an internal thread.

[0011] Furthermore, the internal thread on the nut has a specification of M6X1.0-6H.

[0012] Furthermore, several of the aforementioned anti-slip grooves are distributed in a ring at equal intervals.

[0013] Furthermore, the bottom width of the anti-slip groove is 1.0-1.2mm, and the angle of the anti-slip groove is 30 degrees.

[0014] Furthermore, a through hole is provided at the top of the nut, and the through hole on the nut is connected to the threaded hole on the nut, and the two holes are of the same size.

[0015] 3. Beneficial Effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] This solution, by incorporating self-tapping threads, allows for direct drilling into special material parts, enabling the threaded sleeve body to be tapped and installed. This simplifies the assembly process and improves installation efficiency, making it particularly suitable for special material parts that cannot be directly tapped. The anti-slip groove design effectively enhances the friction between the threaded sleeve body and the part, preventing loosening during use and improving the stability and reliability of the connection. The Torx groove facilitates tightening with a Torx wrench or corresponding screwdriver. Compared to traditional slotted or Phillips head grooves, it transmits torque more effectively, reduces the risk of slippage, and makes installation and disassembly more effortless and convenient. The nut fixedly connected inside the threaded sleeve body provides a standard internal thread connection, meeting the requirements for mating with bolts and other connectors. This achieves the nut function for special material parts, solving the problem of not being able to incorporate nuts due to material and process limitations. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0031] Example:

[0032] Please see Figures 1-5 A special material threaded sleeve includes a threaded sleeve body 1, a nut 2 integrally formed on the top of the threaded sleeve body 1, a self-tapping thread 3 on the outer side of the threaded sleeve body 1, and a nut 4 fixedly connected to the inner side of the threaded sleeve body 1. Several anti-slip grooves 5 are opened on the self-tapping thread 3, and a plum blossom groove 6 is opened on the top of the nut 2. In use, the threaded sleeve body 1 and the nut 2 are integrally formed, which enhances the overall structural strength, avoids the possible breakage or loosening of the split structure under stress, and extends the service life of the threaded sleeve.

[0033] See Figure 1 The self-tapping thread 3 has a tooth angle of 20-30 degrees, which can ensure a balance between cutting performance and connection strength during use.

[0034] See Figure 4 Nut 4 has a screw hole, and the inside of the screw hole has an internal thread.

[0035] See Figure 4 The internal thread specification on nut 4 is M6X1.0-6H.

[0036] See Figure 1 and Figure 3 Several anti-slip grooves 5 are distributed in a ring at equal intervals. During use, the additional anti-slip grooves 5 can effectively enhance the friction between the threaded sleeve body 1 and the parts, prevent the structure from loosening during use, and improve the stability and reliability of the connection.

[0037] See Figure 5 The bottom width of the anti-slip groove 5 is 1.0-1.2mm, and the angle of the anti-slip groove 5 is 30 degrees.

[0038] See Figure 2 A through hole is provided on the top of the nut 2, and the through hole on the nut 2 is connected to the screw hole on the nut 4, and the two holes are the same size.

[0039] Working Principle: During use, firstly, based on the material properties and connection requirements of the part to be installed, drill a pilot hole at the preset installation position of the part that matches the outer diameter of the threaded sleeve body 1. The diameter of the pilot hole should be slightly smaller than the maximum outer diameter of the self-tapping thread 3 on the outer side of the threaded sleeve body 1 to ensure that the self-tapping thread 3 can smoothly cut the material to form a stable connection. Then, insert a Torx wrench or a Torx screwdriver of the corresponding size into the Torx groove 6 at the top of the nut 2, apply axial pressure, and rotate clockwise. At this time, the self-tapping thread 3 on the outer side of the threaded sleeve body 1 begins to cut threads on the inner wall of the pilot hole of the part. As the screwing depth increases, the annularly distributed anti-slip grooves 5 on the self-tapping thread 3 will embed into the part material, further enhancing the friction between the threaded sleeve and the part, effectively preventing loosening during subsequent use. When the bottom of the nut 2 is in contact with the surface of the part, stop screwing in. At this time, the nut 4, which is fixedly connected to the inner side of the threaded sleeve body 1, is connected to the outside through the through hole at the top of the nut 2. The matching bolt can be directly passed through the part to be connected and screwed into the internal thread of the nut 4 to achieve a stable connection with other mechanical parts. The entire installation process does not require additional tapping or injection molding embedding processes, which can enable parts made of special materials to obtain reliable internal thread connection function.
