[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0023] Example: Figure 1-4 As shown, the present invention provides a plastic bottle cap structure, including a bottle cap body 1, and an anti-loss mechanism 2 is provided on the outside of the bottle cap body 1.
[0024] The anti-loss mechanism 2 includes a mounting ring 11. By connecting and fixing the mounting ring 11 to the plastic bottle body 17, the bottle cap body 1 can be connected to the plastic bottle body 17, allowing the bottle cap body 1 to float outside the bottle cap after the plastic bottle is opened. A mounting shell 13 is fixedly connected to the left side of the mounting ring 11. An opening 12 is provided at the connection point between the mounting ring 11 and the mounting shell 13. A screw 14 is threadedly connected to the middle of the left side wall of the mounting shell 13. Rotating the screw 14 allows the arc-shaped clamp 15 to move towards the plastic bottle body 17. The right end of the screw 14 is rotatably connected to the arc-shaped clamp 15. After the arc-shaped clamp 15 contacts the plastic bottle body 17, continued pressure can cause the mounting ring to... 11. The arc-shaped clamp 15 is fixedly connected to the front and rear ends of the middle of the left side wall. The limiting rods 16 can restrict the arc-shaped clamp 15, making it more stable during the movement inside the mounting shell 13. The limiting rods 16 pass through and slide on the front and rear ends of the middle of the left side wall of the mounting shell 13. The middle of the right side wall of the outer periphery of the mounting ring 11 is fixedly connected to the connecting line 10. The end of the connecting line 10 away from the mounting ring 11 is fixedly connected to the connecting block 9. The connecting block 9 is rotatably connected to the middle of the top wall of the dust cover 6. The dust cover 6 can block external dust, thereby preventing dust from entering the interior of the bottle cap body 1 and causing pollution to the interior of the plastic bottle body 17.
[0025] The arc-shaped clamp 15 is fitted with the opening 12 with a clearance. The arc-shaped clamp 15 is located inside the mounting shell 13. The arc-shaped clamp 15 can pass through the opening 12 and fit against the plastic bottle body 17. At the same time, it can move left and right inside the mounting shell 13.
[0026] The inner side of the mounting ring 11 is provided with a plastic bottle body 17, which is threadedly connected to the bottle cap body 1. After moving the bottle cap body 1 to the top of the plastic bottle body 17, rotating the bottle cap body 1 can seal the plastic bottle body 17.
[0027] The bottle cap body 1 has multiple sets of annularly distributed friction-enhancing grooves 3 on its outer side and internal threads 8 on its inner side. The friction-enhancing grooves 3 can increase the friction between the hand and the bottle cap body 1, thereby reducing the difficulty of opening the bottle.
[0028] The bottle cap body 1 has a drain pipe 4 that runs through and is fixedly connected to the middle of the top wall. The drain pipe 4 is located inside the dust cover 6 and can drain the liquid inside the bottle cap body 1 without leaving the plastic bottle body 17.
[0029] The dust cover 6 is provided with a hinge 5 on the rear side. The dust cover 6 is rotatably connected to the bottle cap body 1 through the hinge 5. Rotating the dust cover 6 can insert the sealing plug 7 into the drain pipe 4 or pull it out from the drain pipe 4.
[0030] Among them, a sealing plug 7 is fixedly connected to the middle of the inner bottom wall of the dust cover 6. The sealing plug 7 is in clearance fit with the drain pipe 4. The sealing plug 7 can be inserted into the inside of the drain pipe 4 to perform secondary sealing, so as to avoid liquid contamination of the top of the bottle cap body 1.
[0031] Working principle: After the mounting ring 11 is placed on any position outside the plastic bottle body 17, the screw 14 is rotated. The rotation of the screw 14 causes the arc-shaped clamp 15 to move closer to the plastic bottle body 17. The limiting rod 16 can restrict the arc-shaped clamp 15, so that it moves stably to the right during the movement inside the mounting shell 13. With the cooperation of the arc-shaped clamp 15 and the plastic bottle body 17, the mounting ring 11 is fixed, so that it can be installed on the outside of plastic bottle bodies 17 of different sizes. The bottle cap body 1 is connected to the dust cover 6 using the hinge 5, and then the dust cover 6 is connected and fixed to the mounting ring 11 using the connecting line 10. Finally, the mounting ring 11 is connected to the plastic bottle body 17, so that the bottle cap body 1 will not be lost after being separated from the plastic bottle body 17, and the bottle cap will not be obstructed by the anti-loss mechanism 2 during the rotation of the bottle cap.
