Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, specifically a combined multifunctional nut. Background Technology

[0002] Bolted connections are a common type of connection in engineering structures. They typically use the engagement of bolts and nuts to tightly connect two or more components together, utilizing the friction or bearing capacity of the threads. When the nut is tightened, the threads on the bolt and nut mesh with each other. The rotation of the nut pulls the bolt threads downward, causing the bolt to stretch. This generates tensile force at the connection point, making the two connected components come into close contact and compress. This connection method has advantages such as simple structure, easy disassembly, and reliable connection.

[0003] A combination nut is a special type of nut composed of multiple parts. It has a unique structure and function, is highly adaptable, and is widely used in connection applications requiring high reliability and safety, such as machinery, automobile manufacturing, and aerospace.

[0004] Existing modular nuts require considerable effort and time to rotate and tighten when connected to screws with long thread sections, resulting in low assembly efficiency. To improve the assembly efficiency of modular nuts, a modular multi-functional nut is proposed. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a combined multifunctional nut to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a combined multifunctional nut, comprising a main body, the main body being composed of a fixing sleeve and a nut block, the nut block being composed of a first nut block and a second nut block connected to each other, and the first nut block and the second nut block being connected to each other through a connecting structure, a protrusion being fixedly installed on the outer wall of the end of the nut block, and a threaded hole being opened on the inner wall of the nut block for threaded connection with a screw rod, the outer wall of the fixing sleeve being opened with a mating groove corresponding to the nut block, and the end of the fixing sleeve being opened with a groove corresponding to the protrusion and communicating with the mating groove, and the groove cooperating with the protrusion to restrict the nut block, the end of the fixing sleeve being opened with a through hole corresponding to the screw rod to ensure that the fixing sleeve can be fitted into the screw rod.

[0007] By adopting the above technical solution, users no longer need to rotate the nut from the bottom of the long screw all the way to the fixed point. Instead, they can directly assemble and install the nut block at the point where it needs to be fixed, which simplifies the process of rotating and tightening the nut and thus improves the assembly efficiency.

[0008] Furthermore, a set of inserts are installed on the outer walls of both the first nut block and the second nut block, and the inserts on the outer walls of the first nut block and the second nut block are staggered. The outer walls of both the first nut block and the second nut block are provided with slots corresponding to the inserts, and the first nut block and the second nut block are connected to each other through slots and inserts.

[0009] By adopting the above technical solution, the precise docking of the first nut block and the second nut block can be achieved, thereby ensuring that the threads on the inner walls of the first nut block and the second nut block can be precisely aligned.

[0010] Furthermore, the outer corner of the insert and the corner of the slot opening are designed at bevels to guide the insert into the slot.

[0011] By adopting the above technical solution, the convenience for users when connecting the first nut block and the second nut block is improved.

[0012] Furthermore, the diameter of the through hole is greater than the diameter of the threaded hole and less than the diameter of the end of the nut block located inside the fixing sleeve, and the diameter of the through hole is less than the diameter of the mating groove.

[0013] By adopting the above technical solution, the nut block will not detach from the fixed sleeve during rotation, thus ensuring the stability of the fastening structure.

[0014] Furthermore, multiple sets of protrusions are fixedly installed at equal angles on the outer wall end of the nut block, and the protrusions are designed in a rectangular block shape with beveled corners at the ends.

[0015] By adopting the above technical solution, the groove can be used to better restrict the nut block, preventing the nut block and the fixing sleeve from moving during rotation and thus making it impossible to tighten.

[0016] Furthermore, after the nut block is installed into the mating groove, the nut block is in contact with the inner wall of the mating groove, and the cross-section of one end of the nut block is trapezoidal.

[0017] By adopting the above technical solution, a tight fit is ensured between the nut block and the fixing sleeve.

[0018] Furthermore, the fixing sleeve has a polygonal design, and the thickness of the fixing sleeve is greater than the thickness of the nut block.

[0019] By adopting the above technical solution, the top position of the fixing sleeve is subjected to axial force from the bolt and nut body during the fastening process, and is pressed between the connecting parts, which increases the contact area and disperses the pressure.

[0020] In summary, the present invention has the following main advantages:

[0021] This invention, by providing a through hole at the end of the fixing sleeve, allows the fixing sleeve to be inserted into a long screw first. The first and second nut blocks are then connected to each other in the middle of the screw via inserts and slots. This eliminates the need for the user to rotate the nut from the bottom of the long screw to the fixing point, reducing the time and effort spent on rotating the nut. The design of the inserts and slots makes the connection between the nut blocks more precise. The fixing sleeve then secures the two nut blocks together to form a nut block assembly. Once the fixing sleeve and nut blocks are combined into a nut, a rotational force is applied to the outer wall of the nut for tightening, forming a stable fastening structure. By simplifying the nut rotation and tightening process, quick assembly and disassembly are achieved, improving assembly efficiency. Simultaneously, the top of the fixing sleeve is subjected to axial force from the bolt and nut during tightening, pressing it between the connecting parts, increasing the contact area and dispersing pressure, thereby reducing wear and deformation between the connecting parts and extending the service life of the fastening structure.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] A combination multi-functional nut, such as Figure 1 - Figure 5As shown, it includes main body 1.

[0031] Specifically, the main body 1 consists of a fixing sleeve 10 and a nut block 11. The nut block 11 is composed of a first nut block 111 and a second nut block 112 connected to each other. This allows the user to directly assemble and install the nut block 11 at the point where it needs to be fixed, without having to rotate the nut from the bottom of the long screw all the way to the fixing point. This simplifies the nut rotation and tightening process and improves assembly efficiency. The first nut block 111 and the second nut block 112 are connected to each other through a connecting structure to ensure that the first nut block 111 and the second nut block 112 can be accurately aligned. A protrusion 14 is fixedly installed on the outer wall of the end of the nut block 11, and a protrusion 14 is opened on the inner wall of the nut block 11. The fixed sleeve 10 has a threaded hole 113 for threaded connection with the screw. The outer wall of the fixed sleeve 10 has a mating groove 12 corresponding to the nut block 11 to ensure that the fixed sleeve 10 and the nut block 11 are tightly installed. The end of the fixed sleeve 10 has a groove 15 corresponding to the protrusion 14 and communicating with the mating groove 12. The groove 15 cooperates with the protrusion 14 to restrict the nut block 11, thereby preventing the nut block 11 and the fixed sleeve 10 from separating when the user performs rotation operation, and further ensuring the stability of the fastening structure. The end of the fixed sleeve 10 has a through hole 13 corresponding to the screw to ensure that the fixed sleeve 10 can be fitted into the screw.

[0032] Please see Figure 1 - Figure 5 Each of the first nut block 111 and the second nut block 112 has a set of inserts 17 installed on its outer wall. The inserts 17 on the outer walls of the first nut block 111 and the second nut block 112 are staggered. Each of the first nut block 111 and the second nut block 112 has a slot 16 corresponding to the insert 17 on its outer wall. This is to achieve precise docking of the first nut block 111 and the second nut block 112. The first nut block 111 and the second nut block 112 are connected to each other through the slots 16 and the inserts 17, thereby ensuring that the threads on the inner walls of the first nut block 111 and the second nut block 112 can be precisely aligned.

[0033] Please see Figure 1 - Figure 5 The outer corner of the insert 17 and the opening corner of the slot 16 are designed at an angle to guide the insert 17 into the slot 16, which improves the convenience for the user when connecting the first nut block 111 and the second nut block 112.

[0034] Please see Figure 1 - Figure 5The diameter of the through hole 13 is larger than the diameter of the threaded hole 113 and smaller than the diameter of the end of the nut block 11 located inside the fixing sleeve 10. This ensures that the fixing sleeve 10 can be fitted into the screw through the through hole 13. The diameter of the through hole 13 is smaller than the diameter of the mating groove 12, so that the nut block 11 will not come out of the fixing sleeve 10 during rotation, thus ensuring the stability of the fastening structure.

[0035] Please see Figure 1 - Figure 5 Multiple sets of protrusions 14 are fixedly installed at equal angles on the outer wall end of the nut block 11 to better cooperate with the groove 15 to restrict the nut block 11 and prevent the nut block 11 and the fixing sleeve 10 from moving during rotation, which would prevent them from being tightened. The protrusions 14 are rectangular blocks with beveled corners at the ends, which makes it easier for the protrusions 14 to be inserted into the groove 15.

[0036] Please see Figure 1 - Figure 5 After the nut block 11 is installed into the mating groove 12, the nut block 11 is in contact with the inner wall of the mating groove 12, ensuring that the nut block 11 and the fixing sleeve 10 are tightly installed, and the cross section of one end of the nut block 11 is trapezoidal.

[0037] Please see Figure 1 - Figure 5 The fixed sleeve 10 has a polygonal design, which makes it easy for users to rotate the fixed sleeve 10 with tools, reducing the difficulty of operation. In addition, the thickness of the fixed sleeve 10 is greater than the thickness of the nut block 11, so that the top position of the fixed sleeve 10 is subjected to axial force from the bolt and nut body 1 during the tightening process, and is pressed between the connecting parts, which increases the contact area and disperses the pressure.

[0038] The working principle of this utility model is as follows: When using this combined multifunctional nut to thread-tighten a long screw, the user first needs to insert the fixing sleeve 10 into the long screw along one end of the through hole 13. The first nut block 111 and the second nut block 112 are aligned one nut below the screw fixing point, thus quickly reaching the required fixing position, simplifying the tightening process and improving assembly efficiency. Inserts 17, whose outer walls are staggered, are inserted into the corresponding slots 16 to form a complete nut block 11. During this process, the beveled design of the slot 16 opening corners guides the inserts 17 into the slot 16, facilitating alignment of the threaded surfaces of the first nut block 111 and the second nut block 112. This ensures precise engagement of the threads inside the first nut block 111 and the second nut block 112 to form a threaded hole 113. The threaded hole 113 then tightly engages with the threads on the screw, securing the pre-fitted sleeve. The fixing sleeve 10 of the long screw is installed on the nut block 11, so that the mating groove 12 opened on the outer wall of the fixing sleeve 10 fits with the outer wall of the nut block 11. At the same time, multiple sets of protrusions 14 installed at equal angles at the end of the nut block 11 enter into multiple sets of grooves 15 opened at the end of the mating groove 12, so that the outer wall of the protrusion 14 fits with the inner wall of the groove 15. The protrusion 14 and the groove 15 cooperate to restrict the nut block 11, thereby ensuring that the nut block 11 is firmly fixed by the fixing sleeve 10. After the fixing sleeve 10 and the nut block 11 form the nut body 1, a tool is used to apply rotational force to the outer wall of the nut body 1, so that the nut body 1 rotates to the fixed point and is tightened, thus completing the quick installation and fastening operation. During the fastening process, the top position of the fixing sleeve 10 is subjected to axial force from the bolt and the nut body 1 and is pressed between the connecting parts, which increases the contact area and disperses the pressure, so that the bolt and the nut body 1 form a stable fastening structure.

[0039] During use, if it is necessary to disassemble the connector, a tool is first used to apply a reverse rotational force to the nut body 1, rotating and moving the nut body 1 by the distance of one nut. Then, force is applied to the fixing sleeve 10 to force the fixing sleeve 10 and the nut block 11 installed on its inner wall to separate. Finally, the nut block 11 is split into the first nut block 111 and the second nut block 112, thereby completing the quick disassembly operation and further improving the assembly efficiency.
