[0002] In existing dumbbell assembly systems, dumbbell plates are often fixed using traditional nuts or split self-locking nuts.

[0003] However, these designs generally have the following problems: First, the locking effect is poor, which can easily cause the dumbbell plates to slip during use, posing a safety hazard; second, the split structure design is complex, inconvenient to use, and parts are easily scattered and lost, increasing the user's usage costs and the manufacturer's after-sales service pressure; in addition, traditional nuts often have a rough appearance and poor feel, affecting the user experience.

[0004] Based on this, an integrated self-locking anti-stripping nut is designed. Utility Model Content

[0005] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides an integrated self-locking anti-slip nut, which effectively solves the problems raised in the above background.

[0006] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: an integrated self-locking anti-slip nut, comprising a nut body, a wedge-shaped locking sleeve, a notch, a plum blossom handle, an internal thread, a chamfered surface and a hollow groove, wherein one end of the nut body is connected to a wedge-shaped locking sleeve, one end of the wedge-shaped locking sleeve is provided with a notch, and one end of the nut body is connected to a plum blossom handle, and the nut body, the wedge-shaped locking sleeve and the plum blossom handle are an integrally formed structure.

[0007] Preferably, an internal thread is provided inside the nut body, and a chamfered surface is provided at one end of the nut body.

[0008] Preferably, hollow grooves are distributed around the inner circumference of the wedge-shaped locking sleeve.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] 1. This utility model avoids the tedious installation steps of the split structure through the integrated design, reduces the user's use cost and time, simplifies the use process, and the integrated design does not require additional parts, avoids the problem of scattered parts and loss, and reduces the manufacturer's after-sales service pressure;

[0011] 2. The new and unique wedge-shaped locking sleeve design significantly improves the locking effect, ensuring that the dumbbell pieces are stable and do not fall off, and effectively enhancing the locking force;

[0012] 3. The new model's beautiful appearance, smooth feel and convenient rotation operation greatly enhance the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] Embodiment 1, by Figure 1-Figure 3 The utility model includes a nut body 1, a wedge-shaped locking sleeve 2, a notch 3, a plum blossom handle 4, an internal thread 5, a chamfered surface 6 and a hollow groove 7. One end of the nut body 1 is connected to the wedge-shaped locking sleeve 2, and the wedge-shaped locking sleeve 2 is provided with a notch 3. One end of the nut body 1 is connected to the plum blossom handle 4. The nut body 1, the wedge-shaped locking sleeve 2 and the plum blossom handle 4 are an integrally formed structure.

[0021] An internal thread 5 is provided inside the nut body 1, and a chamfered surface 6 is provided at one end of the nut body 1;

[0022] Hollow grooves 7 are distributed around the inner circumference of the wedge-shaped locking sleeve 2 .

[0023] Working Principle: The anti-slip nut structure is an integrated structure of the nut body 1, the wedge-shaped locking sleeve 2 and the plum blossom handle 4. It is made of high-quality PP material by injection molding, realizing an integrated design. No additional assembly is required, which prevents the scattered loss of parts. The nut body 1 is internally provided with an internal thread 5 for connecting to the dumbbell rod; its outer end is directly connected to the wedge-shaped locking sleeve 2. The unique design of the wedge-shaped locking sleeve 2 can automatically lock the dumbbell pieces when rotating to ensure that they are stable and do not fall off.

[0024] The design of the plum blossom handle 4 not only increases the aesthetics, but also makes it easier for users to rotate the anti-drop nut, thereby improving the convenience of use. The plum blossom design of the handle increases the hand contact area, reduces hand fatigue, and improves the user experience.

[0025] The surface of the product has been finely processed with arcs, chamfers and hollowing, which not only ensures the beautiful appearance, but also avoids the problem of scratching or scratching the hands during use. At the same time, this treatment also enhances the toughness and strength of the product and extends its service life.

[0026] The design of the wedge-shaped locking sleeve 2 utilizes the wedge principle. When the nut is rotated, the wedge-shaped locking sleeve 2 will gradually compress the gap between the dumbbell piece and the nut body 1, forming a strong locking force, effectively preventing the dumbbell piece from slipping during use.
