Description

A convenient sealing device

technical field

The utility model relates to the improvement of the structure of a sealing device, in particular to a portable sealing device.

Background technique

Sealing devices have long been widely used in different fields, and corresponding sealing technologies have been adopted in different fields to improve sealing performance. As consumers pay more and more attention to health, people pay more attention to whether the materials they use are healthy, hygienic and safe materials that are harmless to the human body, such as PC materials, PE materials, PP materials, tempered glass materials and high borosilicate materials. glass material etc.

For example, the lids of common sealed cans, bottles, boxes and other devices are made of PP and silicone materials, and use the principle of vacuum negative pressure to have a sealing effect. The general sealing device formed, for example, the shape of the sealed tank includes the tank body and the tank cover, the joint surface of the tank cover and the tank body is provided with a circumferential groove, the circumferential groove is provided with a sealing ring, and the lower opening of the sealing ring There is a hook, the hook is matched with the lower opening of the tank cover. After adopting this structure, there are two seals between the tank body and the tank cover. The first seal is through the convex surface of the sealing ring, and the second seal is through the upper opening. The side seal, the lower hook buckle can make the sealing ring installed firmly, not deformed and prevent the hand from being scratched by the cover.

What needs to be pointed out in this case is that the above sealing structure and the existing container sealing ring device usually use a sealing ring in the sealing cover and seal by tightening. This kind of sealing effect is poor, inconvenient to use, and does not form an effective sealing system.

Therefore, in view of the above aspects, it is necessary to make reasonable improvements to the prior art.

Utility model content

Aiming at the above defects, the utility model provides a portable sealing device with simple and reasonable structure, convenient processing, high production efficiency, better sealing effect, firmness and durability, so as to solve many deficiencies in the prior art.

In order to achieve the above object, the utility model adopts the following technical solutions:

A convenient sealing device, which is composed of a locking upper cover, a sealing middle cover, a hat-shaped lower cover and a sealing ring. Tighten the upper cover and the cap-shaped lower cover, wherein the bottom surface of the locking upper cover has a cylindrical limit structure extending downward. The outer surface of the cylindrical structure is provided with positioning columns, and the inner surface of the cylindrical structure is provided with bosses. The locking upper cover is fixedly connected with the sealing middle cover through a cylindrical structure; the central part of the cap-shaped lower cover has a columnar body protruding upwards, and the upper and lower ends of the columnar body are respectively provided with a cap top and a cap bottom , a sealing ring is added at the lower edge of the cap-shaped lower cover.

If the locking upper cover is rotated 90° clockwise, the cap-shaped lower cover is lifted upwards, and the boss rotates to the bottom of the cap, driving the sealing ring to move upward.

If the upper cover is locked and rotated 90° counterclockwise, the boss rotates to the top of the cap, which drives the sealing ring to move down.

If the cylinder limiting structure rotates, the rotation angle of the cylinder limiting structure is only rotated by 90° due to the control of the limiting groove.

The beneficial effects of the portable sealing device described in the utility model are:

(1) Simple and reasonable structure, convenient processing, high production efficiency, good sealing effect, firm and durable;

(2) When in use, when the locking upper cover is rotated 90° clockwise, the cap-shaped lower cover is lifted upwards, and the boss rotates to the bottom of the cap, driving the sealing ring to move up to achieve the sealing effect; otherwise, when the locking upper cover When rotating 90° counterclockwise, the boss rotates to the top of the cap, which will drive the sealing ring to move down, which cannot achieve the sealing effect and is easy to take out;

(3) By sealing the limit groove at the middle through hole of the middle cover, when the cylinder limit structure rotates, the rotation angle of the cylinder limit structure can only be rotated by 90° due to the control of the limit groove.
