Detailed Description
The utility model is further described with reference to the following figures and embodiments.
Referring to fig. 1-2, a wear-resistant PET bottle capable of being stably placed includes: the bottle body 1 comprises a bottle body 101, a bottle bottom 102 and a bottle neck 103, wherein the bottle bottom 102 is thickened to form a weight layer 104; the bottle body 1 can be stably placed; a bottle cap 2, wherein the bottle cap 2 is installed on the bottle neck 103 in a threaded mode; the shell 3 is arranged on the bottle cap 2; the air inlet hole 4 is formed in the inner wall of the bottom of the shell 3; and the sealing plug 5 is slidably mounted in the shell 3, and the sealing plug 5 is matched with the air inlet hole 4. When the bottle cap 2 is covered, air in the bottle body 1 can enter the shell 3, and liquid filled in the bottle body 1 is effectively prevented from deteriorating.
Two sliding rods 6 are symmetrically and fixedly installed in the shell 3, a same supporting plate 7 is installed on the sliding rods 6 in a sliding mode, and the supporting plate 7 is fixedly connected with the sealing plug 5. The sliding sleeve is equipped with first spring 8 on slide bar 6, the both ends of first spring 8 respectively with slide bar 6 and backup pad 7 fixed connection. The air in the bottle body 1 can flow into the shell 3 in a single direction, and the reverse flow of the air is prevented.
A piston 9 is fixedly arranged in the bottle cap 2, and the piston 9 is connected with the inner wall of the bottle neck 103 in a sliding and sealing manner. The piston 9 is provided with an accommodating cavity 10, and the inner wall of the accommodating cavity 10 is connected with the shell 3 in a sliding and sealing manner. A second spring 11 is fixedly installed in the accommodating cavity 10, and the bottom end of the second spring 11 is fixedly connected with the shell 3. The bottom of the shell 3 is fixedly provided with a waterproof breathable film 12, and the waterproof breathable film 12 corresponds to the air inlet 4.
