[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-3 This utility model provides an embodiment of a knob decorative locking structure, comprising a knob body 1, an upper outer side of the knob body 1 having a mounting groove 2, a plurality of friction blocks 3 uniformly fixedly connected to the outer side of the mounting groove 2, a decorative body 10 being provided on the upper part of the knob body 1, a button 7 being slidably connected to the inner wall of the decorative body 10, connecting blocks 4 being uniformly fixedly connected to the four sides of the inner wall of the knob body 1, a fixing sleeve 5 being fixedly connected to the opposite side of the connecting blocks 4, a pressing block 6 being fixedly connected to the bottom of the button 7, and the pressing block 6 being slidably connected inside the fixing sleeve 5, the knob body 1 and the... A connecting component is provided on one side of the decorative body 10 to connect the knob body 1 and the decorative body 10. The connecting component includes a limiting groove 8, which is opened on the left and right sides of the inner wall of the knob body 1. A buckle 11 is slidably connected inside the limiting groove 8. Positioning holes 9 are opened on the front and rear sides of the upper part of the knob body 1. Positioning pins 12 are slidably connected inside the positioning holes 9. The button 7 is slidably connected inside the knob body 1. The positioning pins 12 are fixedly connected to the front and rear sides of the lower part of the decorative body 10. The buckle 11 is fixedly connected to the left and right sides of the lower part of the decorative body 10.

[0029] When it is necessary to lock the knob decorative part, push the decorative part body 10 to move the buckle 11 and the positioning post 12. Under pressure, the buckle 11 slides into the limiting groove 8, and the positioning post 12 slides into the positioning hole 9 to prevent relative rotation between the knob body 1 and the decorative part body 10. This improves the production efficiency of the knob decorative part locking structure and ensures that the connection between the knob body 1 and the decorative part body 10 is firm and reliable.

[0030] Reference Figures 1-3 The knob body 1 is made of polycarbonate, the friction block 3 is made of rubber, the decorative part body 10 is made of aluminum alloy, the button 7 is made of polypropylene, and the positioning post 12 is made of stainless steel.

[0031] By using polycarbonate material to ensure the strength and durability of the knob body 1, it can withstand long-term use without being easily damaged. By using rubber material to improve the wear resistance and pressure resistance of the friction block 3, the impact of friction and pressure on the components can be effectively reduced, extending their service life. By using aluminum alloy material to improve the corrosion resistance and durability of the decorative part body 10, it can resist the erosion of the external environment and maintain the appearance and performance of the decorative part. By using polypropylene material to ensure the durability of the button 7, it can maintain good performance during frequent operation. By using stainless steel material to ensure the tensile strength and wear resistance of the positioning post 12, it can effectively resist the pulling of external forces and long-term wear, ensuring its stability and durability. In this way, the knob and decorative part can achieve higher durability and a longer service life while ensuring functionality.

[0032] Working principle: When the knob decorative part needs to be locked, push the decorative part body 10 to move the buckle 11 and the positioning post 12. Under pressure, the buckle 11 slides into the limiting groove 8, and the positioning post 12 slides into the positioning hole 9 to prevent the relative rotation of the knob body 1 and the decorative part body 10. This improves the production efficiency of the knob decorative part locking structure and ensures that the connection between the knob body 1 and the decorative part body 10 is firm and reliable.
