Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. It is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments, and that all other embodiments obtained by persons of ordinary skill in the art without making creative efforts based on the embodiments in the present utility model are within the protection scope of the present utility model.

Examples:

referring to fig. 1-3, the upper side of the upper bottle cap 1 is fixedly connected with a lower bottle cap 2, the inner side of the lower bottle cap 2 is fixedly connected with a bottle cap inner plug 3, the upper bottle cap 1 can play a role in installing and fixing the lower bottle cap 2, the lower bottle cap 2 can be connected with the bottle cap inner plug 3, the inner part of the upper bottle cap 1 is fixedly connected with a threaded block 4, the upper bottle cap 1 can also install and fix the threaded block 4, the threaded block 4 can facilitate the connection between the upper bottle cap 1 and the lower bottle cap 2 and the outer bottle, and the upper bottle cap 1, the lower bottle cap 2, the bottle cap inner plug 3 and the threaded block 4 can form important parts in the existing bottle cap body.

Specifically, the height of the upper bottle cap body 1 is 10.2 mm-10.3 mm, the height of the lower bottle cap body 2 is 17.22 mm-17.42 mm, the height from the top of the lower bottle cap body 2 to the bottom of the upper bottle cap body 1 is 29.02 mm-29.62 mm, the outer diameter of the upper bottle cap body 1 is 41.7 mm-42.3 mm, the inner diameter of the upper bottle cap body 1 is 37.2 mm-37.8 mm, the outer diameter of the lower bottle cap body 2 is 40.8 mm-41.4 mm, the inner diameter of the lower bottle cap body 2 is 35mm, the distance between the bottle cap inner plugs 3 is 27.74 mm-27.78 mm, and the interval between screw blocks 4 is 4.23 mm-4.3 mm.

Specifically, the inner plug 3 of the bottle cap is shorter than the inner plug 3 of the bottle cap in the existing bottle cap, the distance between the inner sides of the inner plug 3 of the bottle cap is reduced, the gradient of the inner plug 3 of the bottle cap can be effectively reduced, accordingly, when the upper bottle cap body 1 and the lower bottle cap body 2 are connected with an external bottle body through rotation, the upper bottle cap body 1 and the lower bottle cap body 2 can smoothly rotate towards the bottle mouth, a certain torque value is achieved during rotation, meanwhile, the gradient of the inner plug 3 of the bottle cap can effectively resist the pressure brought by part of the bottle mouth to the upper bottle cap body 1 and the lower bottle cap body 2, and accordingly the protection effect on the bottle cap is improved.

The working principle and the using flow of the utility model are as follows: when the device is used, people can rotate the upper bottle cap body 1 and the lower bottle cap body 2 to the external bottle body, the direct distance of the inner plug 3 of the bottle cap is shortened when the bottle cap is rotated, and the distance between the inner sides of the two sides is relatively reduced, so that the upper bottle cap body 1 and the lower bottle cap body 2 can be smooth enough when being connected with the external bottle body, and the torque value generated during rotation can effectively resist the pressure between the bottle body and the upper bottle cap body 1 and the lower bottle cap body 2, so that the problem that some application scenes need to automatically screw a cap machine, the torque is large when the machine screw cap force is large, the top of the bottle cap can be subjected to outward extrusion force, and the top of the bottle cap has the risk of jacking up can be solved.
