TECHNICAL FIELD

[0001] The utility model relates to mechanical parts technical field especially relates to a novel round nut with locking and anti-loose function. BACKGROUND

[0002] In prior art, commonly used round nut locking anti-loose structure mainly has two kinds: the first kind is to adopt round nut plus stop washer or locking buckle, this mode requires machining U-shaped groove on the shaft, but machining U-shaped groove on the shaft not only will result in the increase of processing difficulty and cost, also will reduce the strength of the shaft, especially for the shaft of larger size, it is quite inconvenient to machine U-shaped groove, secondly, the installation and adjustment of stop washer or locking buckle are more complex, the control precision of axial gap is difficult to guarantee, and the locking is not firm or too tight easily appears, in addition, the installation process of this mode needs to accurately clamp the stop ear or locking buckle into the groove, its operation is more cumbersome, and error is easy to occur. And the second kind is to adopt double round nut, this mode can realize effective locking, but needs larger installation space, thereby will increase the volume and weight of equipment, leads to difficult to apply in narrow space. More importantly, whether it is to adopt stop washer structure or double round nut structure, when disassembling, it needs to disassemble the nut laboriously, the operation is inconvenient, increases the difficulty and time cost of maintenance, reduces the maintenance efficiency of equipment. These problems limit the application range and performance promotion of existing round nut locking anti-loose structure. SUMMARY

[0003] Therefore, in order to solve the above problems, the utility model discloses a novel round nut with locking and anti-loose function, which comprises a nut and a screw, the nut is uniformly provided with a plurality of threaded holes and a plurality of mounting holes in the circumferential direction, the threaded holes and the mounting holes are annularly distributed, and the threaded holes and the mounting holes are alternately arranged, and the screw is arranged in the threaded hole.

[0016] The technical scheme of the utility model will be described clearly and completely in conjunction with the drawings, obviously, the described embodiment is a part of the embodiment of the utility model, not all embodiments. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the scope of protection of the utility model.

[0017] In the description of the utility model, it is understood that the orientation or position relationship indicated by "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "horizontal", "vertical" and the like is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the utility model, and does not indicate or imply that the indicated device or element must have a particular orientation, so it cannot be understood as a limitation on the utility model.

[0018] It needs to be specially pointed out that "horizontal", "vertical" in the utility model are all used to illustrate approximate position relationship, and not strict "horizontal plane" or "vertical plane".

[0019] like Figures 1-3 The image shows a novel round nut with locking and anti-loosening functions according to a preferred embodiment, comprising: a nut 1 and a screw 2. The nut 1 has a plurality of threaded holes 3 and a plurality of mounting holes 4 evenly distributed along its circumference. The threaded holes 3 and the mounting holes 4 are arranged in a ring, and the threaded holes 3 and the mounting holes 4 are alternately arranged in sequence. The screw 2 is disposed in the threaded hole 3. Furthermore, the mounting holes 4 can be used for preliminary fixing and positioning of the nut 1, which helps to ensure precise control of axial clearance.

[0020] Furthermore, as a preferred embodiment, an outer groove 5 is provided on the outer wall of the nut 1.

[0021] Furthermore, as a preferred embodiment, an inner groove 6 is provided on the inner wall of the nut 1.

[0022] Furthermore, as a preferred embodiment, the outer groove 5 is arranged in a ring shape, and the center of the outer groove 5 coincides with the center of the nut 1.

[0023] Furthermore, in a preferred embodiment, the inner groove 6 is arranged in a ring shape, and the center of the inner groove 6 coincides with the center of the nut 1.

[0024] Furthermore, as a preferred embodiment, the outer groove 5 is disposed around the inner groove 6, and the outer groove 5 and the inner groove 6 maintain a certain distance along the axial direction. Furthermore, by providing the outer groove 5 and the inner groove 6, it is beneficial to reduce the weight of the nut 1 and avoid stress concentration, thereby increasing the structural strength of the nut 1.

[0025] Furthermore, in a preferred embodiment, the mounting hole 4 is directly opposite the outer groove 5 and the inner groove 6.

[0026] Furthermore, in a preferred embodiment, the threaded hole 3 is positioned directly opposite the outer groove 5 and the inner groove 6, and the threaded hole 3 penetrates the nut 1 axially, connecting the outer groove 5 and the inner groove 6.

[0027] Furthermore, as a preferred embodiment, the number of threaded holes 3 is at least three, and the number of mounting holes 4 is at least two.

[0028] The working principle of this utility model is as follows: First, the nut 1 is sleeved on the external rotating shaft, and the internal thread 7 of the nut 1 is engaged with the external thread of the rotating shaft. Then, a bolt is installed in the mounting hole 4, and the nut 1 is initially fixed to the outer shell of the rotating shaft by the bolt. Then, the screw 2 is screwed into the threaded hole 3. When the screw 2 is pre-tightened, the radial pressure generated by the screw 2 will cause static friction between the internal thread of the nut 1 and the external thread of the rotating shaft. The static friction force resists the rotational tendency caused by the axial load, thereby achieving a firm connection between the nut 1 and the rotating shaft. The nut 1 is firmly locked on the rotating shaft. When it is necessary to disassemble the nut 1, it is only necessary to loosen the screw 2 and the bolt to remove the nut 1 from the rotating shaft. The disassembly and assembly process is relatively simple and will not damage the structure of the rotating shaft.

[0029] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
