Description

Technical Field

[0001] This utility model relates to the field of novel nut technology, specifically to novel nuts. Background Technology

[0002] Nuts, as a type of fixed structural component, play a fixing role by tightening with bolts or screws, and are used in various fields.

[0003] A search revealed CN221857266U, which discloses a novel press-fit nut. The nut describes a nut that includes a nut seat and embossed teeth formed around its periphery. The nut seat has internal threads, and two symmetrical guide posts on its peripheral wall. An outer nut seat is fitted onto the nut seat via these guide posts. The guide posts have internal mounting holes, and the outer nut seat has corresponding external mounting holes. The internal and external mounting holes are connected by a mounting insert. The outer nut seat also has a locking opening that communicates with the external mounting holes and has a larger diameter. A retaining spring for fixing the mounting insert is installed within the locking opening. This invention has the advantages of high versatility and good performance.

[0004] The aforementioned patents still have shortcomings in actual use. When using existing technologies, the disassembly and assembly space is small, and when using tightening tools, the operating range is narrow, which means that the tightening tools can only be rotated multiple times over a short distance, making the operation extremely inconvenient.

[0005] Based on this, this utility model discloses a novel nut. Utility Model Content

[0006] To address the problem presented in the background art that existing technologies suffer from limited space for assembly and disassembly, and the narrow operating range of tightening tools restricts their operation to short-distance, multiple rotations, resulting in significant inconvenience, this invention provides a novel nut. The nut comprises a structural nut with an internal thread at its center, a sliding frame fitted around its exterior, and a sliding groove on each outer vertical structural surface of the structural nut. A sliding block is fixed to each vertical inner wall of the cavity enclosed by the sliding frame, and the sliding block slides within the sliding groove. Auxiliary components are mounted on the structural nut and the sliding frame.

[0007] As a further improvement to this technical solution, the auxiliary component includes a telescopic hole, and the structural nut has a telescopic hole on its block. A limiting short shaft is slidably arranged inside the telescopic hole, and a limiting spring is provided at the end of the telescopic hole near the center of the structural nut. One end of the limiting spring is connected to the inner wall of the telescopic hole, and the other end of the limiting spring is connected to the limiting short shaft. A first magnet is fixedly installed at the end of the limiting short shaft away from the limiting spring.

[0008] As a further improvement to this technical solution, the limiting spring does not deform when it is not in operation, and at this time the block of the first magnet is completely located inside the opening space of the telescopic hole.

[0009] As a further improvement to this technical solution, a structural groove is provided at a lower position on one outer structural surface of the sliding sleeve frame. A threaded hole is provided on the vertical end face of the structural groove. An insertion hole is provided at the end of the threaded hole away from the structural groove. An adsorption cavity is provided on the inner wall surface of the insertion hole near the center of the sliding sleeve frame. The adsorption cavity penetrates the frame body of the sliding sleeve frame. The opening size of the insertion hole is larger than the opening size of the threaded hole and the adsorption cavity.

[0010] As a further improvement to this technical solution, the height of the sliding sleeve is the same as the height of the structural nut. When the sliding sleeve is completely fitted outside the structural nut, the opening space of the adsorption cavity is connected to the opening space of the telescopic hole, and at this time the central axis of the adsorption cavity coincides with the central axis of the telescopic hole, and the cross-sectional radius of the adsorption cavity is the same as the cross-sectional radius of the telescopic hole.

[0011] As a further improvement to this technical solution, a screw is rotatably installed inside the threaded hole, a second magnet is fixedly installed at the end of the screw near the insertion hole, and a dial is installed at the end of the screw away from the second magnet. The cross-sectional size of the second magnet is smaller than that of the screw, and the second magnet can move with the screw in the opening space of the threaded hole. When the entire body of the second magnet is inserted into the insertion hole, the structural surface of the dial is close to but does not contact the vertical structural surface of the opposite structural groove.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0013] 1. In this new type of nut, the point of force application can be changed through the cooperation between the structural nut and the sliding sleeve, so as to realize the installation and disassembly of the nut in a narrow space, ensuring that the disassembly tool has enough room to operate, and facilitating the subsequent application of rotational force to the structural nut.

[0014] 2. In this new type of nut, with the assistance of auxiliary components, the structural nut can lock onto the sliding sleeve when no sliding sleeve is needed. When the sliding sleeve is needed, the sliding sleeve can slide along the outside of the structural nut, facilitating the installation and disassembly of the structural nut.

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Therefore, this utility model provides a new type of nut, see [reference]. Figures 1-5 As shown, the structure includes a structural nut 1 with an internal thread 2 at its center, a sliding sleeve 3 fitted around the structural nut 1, a sliding groove 4 on each outer vertical structural surface of the structural nut 1, and a sliding block 5 fixedly attached to each vertical inner wall of the cavity enclosed by the sliding sleeve 3. The sliding block 5 slides inside the sliding groove 4. Auxiliary components are installed on the structural nut 1 and the sliding sleeve 3. When the sliding sleeve 3 is fitted around the structural nut 1, the inner wall of the cavity enclosed by the sliding sleeve 3 is in contact with the outer structural surface of the structural nut 1. The height of the sliding groove 4 is less than the height of the structural nut 1. The fixed position of the sliding block 5 is located slightly lower than the body of the sliding sleeve 3. By applying a pulling force to the sliding sleeve 3, the sliding sleeve 3 can move along the structural nut 1 with the cooperation of the sliding groove 4 and the sliding block 5.

[0024] The auxiliary component includes a telescopic hole 6. The structural nut 1 has a telescopic hole 6 on its body. A limiting short shaft 7 is slidably disposed inside the telescopic hole 6. A limiting spring 9 is disposed at the end of the telescopic hole 6 near the center of the structural nut 1. One end of the limiting spring 9 is connected to the inner wall of the telescopic hole 6, and the other end is connected to the limiting short shaft 7. A first magnet 8 is fixedly installed at the end of the limiting short shaft 7 away from the limiting spring 9. The cross-sectional dimension of the first magnet 8 is smaller than that of the telescopic hole 6. The first magnet 8 can move with the limiting short shaft 7 inside the telescopic hole 6. During the process of the limiting short shaft 7 moving outward from the telescopic hole 6 under force, the limiting spring 9 is stretched and generates a reaction force. After the external force disappears, the reaction force of the limiting spring 9 allows the limiting short shaft 7 and the first magnet 8 to return to their original positions.

[0025] When the limit spring 9 is not in operation, it does not deform, and at this time the block of the first magnet 8 is completely located inside the opening space of the telescopic hole 6.

[0026] A structural groove 13 is formed on the lower part of one outer structural surface of the sliding sleeve 3. A threaded hole 10 is formed on the vertical end face of the structural groove 13. An insertion hole 11 is formed at the end of the threaded hole 10 away from the structural groove 13. An adsorption cavity 12 is formed on the inner wall surface of the insertion hole 11 near the center of the sliding sleeve 3. The adsorption cavity 12 penetrates the frame body of the sliding sleeve 3. The opening size of the insertion hole 11 is larger than the opening size of the threaded hole 10 and the adsorption cavity 12. The opening space of the structural groove 13 is cylindrical, and the central axis of the structural groove 13 coincides with the central axis of the threaded hole 10. The opening shape of the insertion hole 11 is cubic, and the cross-sectional diameters of the threaded hole 10 and the adsorption cavity 12 are both smaller than the opening edge length of the insertion hole 11.

[0027] The height of the sliding sleeve 3 is the same as the height of the structural nut 1. When the sliding sleeve 3 is completely fitted outside the structural nut 1, the opening space of the adsorption cavity 12 is connected to the opening space of the telescopic hole 6, and at this time, the central axis of the adsorption cavity 12 coincides with the central axis of the telescopic hole 6, and the cross-sectional radius of the adsorption cavity 12 is the same as the cross-sectional radius of the telescopic hole 6. When the sliding sleeve 3 is completely fitted outside the structural nut 1, the first magnet 8 can enter the interior of the insertion hole 11 through the adsorption cavity 12.

[0028] A screw 14 is rotatably mounted inside the threaded hole 10. A second magnet 15 is fixedly mounted at the end of the screw 14 near the insertion hole 11. A dial 16 is mounted at the end of the screw 14 away from the second magnet 15. The cross-sectional size of the second magnet 15 is smaller than that of the screw 14, and the second magnet 15 can move with the screw 14 in the opening space of the threaded hole 10. When the entire body of the second magnet 15 is inserted into the insertion hole 11, the structural surface of the dial 16 is close to but does not contact the vertical structural surface of the opposite structural groove 13. When the sliding sleeve 3 is completely fitted outside the structural nut 1, the rotating disk 16 rotates the screw 14 inside the threaded hole 10, causing the second magnet 15 to enter the insertion hole 11. The first magnet 8 and the second magnet 15 generate an attraction force, causing the first magnet 8 to pass through the adsorption cavity 12 and enter the inner wall of the insertion hole 11 and attract the second magnet 15, thus locking the position of the sliding sleeve 3 and preventing the sliding sleeve 3 from sliding outside the structural nut 1. At this time, the limiting spring 9 is stretched and generates a reaction force. One end of the limiting short shaft 7 is located inside the telescopic hole 6, and the other end is located inside the adsorption cavity 12.

[0029] During operation, through the cooperation of the structural nut 1, sliding sleeve 3, and auxiliary components, when disassembling the tightened structural nut 1, a turning force is first applied to the actuating disc 16. The actuating disc 16 drives the screw 14 to rotate, causing the second magnet 15 inside the insertion hole 11 to move towards the structural groove 13. The second magnet 15 gradually moves away from the area where it is attracted to the first magnet 8. As the screw 14 continues to rotate, the second magnet 15 enters the interior of the threaded hole 10, and the first magnet 8 disengages from the area where it is attracted to the second magnet 15. Within the attached range, at this time, the reaction force generated by the stretched limiting spring 9 will pull the limiting short shaft 7 into the telescopic hole 6. The first magnet 8 will then disengage from the insertion hole 11 and the adsorption cavity 12 and return to the inside of the telescopic hole 6, thereby releasing the locking effect on the sliding sleeve 3. Then, a force is applied to the sliding sleeve 3. With the cooperation of the sliding groove 4 and the sliding block 5, the sliding sleeve 3 moves along the outside of the structural nut 1, changing the point of force application on the structural nut 1, so that rotational force can be applied to the structural nut 1 in a narrow space.

[0030] In summary, this effectively solves the problem that existing technologies have limited space for disassembly and assembly, and when using tightening tools, the limited operating range means that the tightening tools can only be rotated multiple times over a short distance, making operation extremely inconvenient.
