technical field

The utility model relates to the field of novel container equipment, in particular to a fall-proof and fall-off non-rotating tank cover.

Background technique

With the improvement of people's living standards, the number of household and commercial cans has increased sharply, and the styles of cans and lids on the market have also increased. Traditional cans use a rotary locking design, which has good airtightness, but the opening and closing process is relatively slow. It is laborious. For people with less strength, the opening and closing process of the can lid is more troublesome, and the tank body cannot provide a certain buffer when it falls off or hits a heavy object. , and the traditional tank cover uses a rotary design, which is expensive, and it is difficult to find the thread position during the tightening process of the tank cover, which may easily cause the tank body to slip or not be tightened tightly, resulting in greater losses.

Utility model content

The purpose of this utility model is to provide an anti-drop, anti-falling, non-rotating tank cover in order to solve the above problems.

The utility model realizes above-mentioned purpose through following technical scheme:

An anti-drop and anti-falling non-rotating tank cover, including a cover body, a negative pressure tube, a top plate, a button, and a first sealing ring.

When the cover body is closed, a small amount of air in the tank can flow out to form a negative pressure, which is beneficial to Due to the adsorption force of the lid, the bulge height of the second sealing ring is relatively low. When the jar falls, the external force makes the first sealing ring open. Since the bulge of the second sealing ring is relatively low, the first sealing ring When the ring is slightly opened by external force, the adsorption capacity of the second sealing ring will not be affected, thereby achieving a double sealing effect.

In order to further improve the ease of use of the non-rotating tank cover, the cover body is connected to the second sealing ring by glue, and the first seal ring is connected to the cover body by glue.

In order to further improve the convenience of use of the anti-drop, anti-fall, and non-rotating tank cover, the negative pressure tube is connected to the one-way tube through a buckle, and the negative pressure tube is connected to the negative pressure switch through a clamp.

In order to further improve the ease of use of the non-rotating tank cover, which is anti-drop and fall-off, the air guiding plate is connected to the air guiding tube through a clamp.

In order to further improve the convenience of use of the non-rotating tank cover, which is anti-falling and falling off, the cover body and the top plate are connected by a sealant.

In order to further improve the ease of use of the anti-drop, anti-fall, and non-rotating tank cover, the strut is connected to the exhaust channel through a clamp, the strut is connected to the spring through bolts, and the spring is connected to the The sealing blocks are connected by screws.

In order to further improve the ease of use of the anti-drop, anti-drop, and non-rotating tank cover, the sealing block is connected to the top plate by bolts, and the top plate is connected to the button by screws.

The beneficial effect is that it is more convenient to use, changes the traditional can lid rotary design style, has better storage effect, lower cost, simpler opening and closing process, eliminates the disadvantages of the previous can lid closure, and has better airtightness. It is made of rubber material and has a certain anti-fall ability. A negative pressure environment is formed inside the tank, which improves the problem that the tank cover is easy to slip off in the past. It has a longer service life, better effect and higher economic benefits.
