Description

Technical Field

[0001] This utility model relates to the field of sealing cap technology, and in particular to a sealing cap for a rubber bucket. Background Technology

[0002] Packaging drums are a type of packaging structure widely used for the storage and transportation of various liquids. They are characterized by being unbreakable, rust-free, and lightweight, and also have advantages such as good oil resistance and strong corrosion resistance. They are widely used in industries such as chemical, pesticide, pharmaceutical, food, hardware, electronics, and electromechanical. Most existing packaging drums have simple methods of fixing the lid and the drum body, which means that the liquid inside the packaging drum is prone to shaking during storage and transportation, resulting in poor sealing. Moreover, for drums containing components that are easy to solidify, the lid and the drum body are prone to sticking together, making it very inconvenient to open.

[0003] Therefore, considering the aforementioned technical problems, it is necessary to provide a new technical solution. Utility Model Content

[0004] The purpose of this invention is to provide a sealing cap for a plastic bucket that offers better sealing performance and is easier to open.

[0005] To solve the above-mentioned technical problems, this utility model provides a sealing cap for a glue bucket, the specific technical solution of which is as follows:

[0006] A sealing cap for sealing a plastic bucket with a smooth inner wall includes a cap body, a sealing groove is provided on the outer circumferential wall of the cap body, and a sealing ring is tightly fixed in the sealing groove. The sealing groove and the sealing ring are multiple and mutually compatible.

[0007] The upper surface of the cover has a first threaded hole with internal threads at its center. A first nut is threaded into the first threaded hole. One end of the first nut is adapted to the first threaded hole, and the other end is larger than the first threaded hole and exposed on the outside of the cover. The end of the first nut located on the outside of the cover has a second threaded hole with internal threads. The second threaded hole is a blind hole, and a second nut is threaded into the second threaded hole. The size of the second nut is smaller than the size of the first nut.

[0008] Preferably, the side of the cover facing the inside of the glue bucket is concave in an arc shape from the periphery to the center to form a spherical cavity, which communicates with the first threaded hole.

[0009] Preferably, the second threaded hole is T-shaped, and the shape of the second nut is adapted to the second threaded hole so that the second nut is concealed in the second threaded hole.

[0010] Preferably, the central axes of the first nut and the second nut are collinear.

[0011] Preferably, the diameter of the sealing ring is greater than the depth of the sealing groove so that the sealing ring protrudes from the sealing groove and abuts against the inner wall of the glue bucket.

[0012] Preferably, the sealing groove and the sealing ring are two mutually compatible ones, with the two sealing grooves located near the upper and lower ends of the cover, and the sealing grooves arranged in a ring around the circumference of the cover.

[0013] The sealing cap for a rubber bucket of this utility model has the following beneficial effects:

[0014] The sealing cap for the glue bucket of this utility model uses a sealing groove on the cap body to fix the sealing ring, and the elasticity of the sealing ring to achieve a tight fit between the cap body and the glue bucket, preventing liquid from overflowing. The cavity structure at the bottom of the cap body can also effectively guide the liquid flow when shaken, preventing excessive pressure relief on the periphery of the cap body, further improving the sealing effect. At the same time, the combination of large and small nuts in the form of a push-button cap makes it easier to open the nuts and remove the cap body with tools such as hooks, effectively reducing the situation where the cap cannot be opened due to the solidification of easily solidified liquids.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Example

[0021] Please see Figures 1 to 2 A sealing cap for sealing a plastic bucket with a smooth inner wall includes a cap body 1. A sealing groove 11 is provided on the outer side wall of the cap body 1. A sealing ring 4 is tightly fixed in the sealing groove. The sealing groove and the sealing ring are multiple layers that are mutually compatible.

[0022] The upper surface of the cover 1 has a first threaded hole 13 with internal threads at its center. A first nut 2 is threaded into the first threaded hole. One end of the first nut is adapted to the first threaded hole, and the other end is larger than the first threaded hole and exposed on the outside of the cover. The end of the first nut located on the outside of the cover has a second threaded hole 21 with internal threads. The second threaded hole is a blind hole, and a second nut 3 is threaded into the second threaded hole. The size of the second nut is smaller than the size of the first nut.

[0023] The cover 1 has an arc-shaped indentation on the side facing the inside of the glue bucket, forming a spherical cavity 12, which is connected to the first threaded hole.

[0024] The second threaded hole 21 is T-shaped, and the shape of the second nut is adapted to the second threaded hole so that the second nut can be hidden in the second threaded hole.

[0025] The central axes of the first nut 2 and the second nut 3 are collinear.

[0026] The diameter of the sealing ring 4 is greater than the depth of the sealing groove 11 so that the sealing ring protrudes from the sealing groove and abuts against the inner wall of the glue bucket.

[0027] The sealing groove 11 and the sealing ring 4 are two mutually compatible grooves. The two sealing grooves are located near the upper and lower ends of the cover 1, and the sealing grooves are arranged in a ring around the circumference of the cover.

[0028] In this embodiment, when using the sealing cap for the glue bucket, the liquid is poured into the glue bucket for storage. The first nut 2 is screwed into the first threaded hole 13 in the center of the cap body. Then, the cap body is placed on top of the glue bucket and pressed down. The cap body is sealed tightly with the glue bucket through the sealing ring. Then, the second nut 3 is screwed into the second threaded hole of the first nut. This allows the small nut and the large nut to cooperate to distribute the force and prevent loosening. At the same time, it gives the first nut a fine adjustment capability. When the first nut is stuck by the solidifying liquid, the first nut can be unscrewed by the cooperation of the second nut.

[0029] The beneficial effects of this utility model are as follows: the sealing ring is fixed by the sealing groove on the cover, and the elasticity of the sealing ring is used to achieve a tight fit between the cover and the glue bucket, preventing liquid from overflowing. The cavity structure at the bottom of the cover can also effectively guide the liquid flow when shaken, preventing excessive pressure relief of the liquid on the periphery of the cover, further improving the sealing effect. At the same time, the combination of large and small nuts in the form of a push-type cover makes it easier to open the nuts and remove the cover with tools such as hooks, effectively reducing the situation where the cover cannot be opened due to the solidification of easily solidified liquids.

[0030] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications and variations to the above embodiments within the scope of the present invention.
