Description

Technical Field

[0001] The utility model relates to the technical field of plastic barrels, in particular to a plastic barrel with strong sealing performance. Background Art

[0002] Plastic barrels are mostly made of polyethylene, polypropylene and other plastics by blow molding and injection molding. They are used as outer packaging for liquid and solid items in the chemical, pesticide, pharmaceutical, food, hardware and electronics, electromechanical and other industries.

[0003] After searching, a Chinese patent with publication number CN216233884U discloses a plastic barrel with strong sealing performance. The technical points are: solving the problem that the sealing effect of the material pipe of the traditional plastic barrel is poor, which is easy to cause volatilization. On the other hand, traditional plastic barrels are coated with brown paint to avoid light, which makes it difficult to observe the usage of the raw materials inside the bottle. However, since it is difficult to clean the inside of the plastic barrel due to the technology, the reusability of the device is relatively poor, and it is troublesome to take out some of the internal raw materials, which is not only time-consuming and labor-intensive, but also easy to scatter when pouring.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0007] By adopting the above scheme, when using the device, first place the trapezoidal circular gasket inside the barrel body so that the bottom surface of the trapezoidal circular gasket contacts the first gasket, and then rotate the barrel cover to thread the barrel cover and the barrel body. When the barrel cover is rotated downward, the second gasket will contact the trapezoidal gasket. When the barrel cover is rotated to the limit, the trapezoidal gasket will fully squeeze the first gasket and the second gasket, so that the barrel cover can seal the barrel body, thereby achieving the effect that the device can seal the plastic barrel according to demand.

[0008] Optionally, a connection nozzle is fixedly connected to the upper surface of the barrel cover, and the connection nozzle includes an external thread and an internal thread.

[0012] Furthermore, a corrugated hose is inserted into the interior of the connecting nozzle, and a connecting head is fixedly connected to the upper end of the corrugated hose.

[0013] By adopting the above scheme, the flow direction of the liquid in the barrel body can be changed through the provided corrugated hose, which facilitates the flow of liquid into some equipment with smaller diameters, effectively avoiding waste when adding liquid. The provided connector can facilitate the installation of the corrugated hose and prevent the corrugated hose from falling into the barrel body.

[0014] Furthermore, the connector includes a circular pad and a second external thread, the pitch of the second external thread is the same as that of the internal thread, a through hole is opened inside the connector, and the lower end of the through hole is connected to the corrugated hose.

The external thread 2 can be conveniently connected with the internal thread of the connecting nozzle, and the through hole can be conveniently connected with the corrugated hose, so that the liquid in the barrel body can enter the corrugated hose conveniently.

[0016] Furthermore, a threaded hole is provided inside the barrel cover, and a sealing plug is threadedly connected to the inner wall of the threaded hole.

[0017] By adopting the above scheme, the sealing plug can be conveniently installed through the threaded hole, and the barrel can be ventilated when the liquid flows out by removing the sealing plug, thereby accelerating the outflow speed of the liquid.

[0018] Furthermore, a liquid level sensor is installed inside the barrel cover, a fixing ring is fixedly connected to the inner bottom wall of the barrel body, and the outer surface of the liquid level sensor is plugged into the fixing ring.

[0019] By adopting the above scheme, the liquid level sensor can be used to conveniently detect the liquid capacity inside the barrel body, and the bottom of the liquid level sensor can be conveniently fixed by the fixed ring, so as to prevent the internal liquid from shaking and causing the liquid level sensor to break when the barrel body moves.

[0020] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0021] 1. The utility model is provided with a barrel cover, a trapezoidal gasket, a gasket 1 and a gasket 2. When using the device, the trapezoidal round gasket is first placed inside the barrel body so that the bottom surface of the trapezoidal round gasket contacts the gasket 1, and then the barrel cover is rotated to make the barrel cover and the barrel body threadedly connected. When the barrel cover is rotated downward, the gasket 2 contacts the trapezoidal gasket. When the barrel cover is rotated to the limit, the trapezoidal gasket fully squeezes the gasket 1 and the gasket 2, so that the barrel cover can achieve a sealing effect on the barrel body, thereby achieving the effect that the device can seal the plastic barrel according to demand.

[0022] 2. The utility model is provided with components such as a sealing cover, a connecting nozzle, a connecting head and a bellows. When using the device, firstly rotate and remove the sealing cover and the sealing plug, take out the corrugated hose through the connecting head, and then turn the corrugated hose upward to threadably connect the external thread of the connecting head with the internal thread of the connecting nozzle. At this time, the barrel body is tilted, and the liquid inside will flow out through the corrugated hose, so that the device can conveniently take out part of the liquid according to needs.
