A sealing device is mainly used for sealing the mouth of a small-particle solid bag such as rice, flour, powder and the like, when in use, one corner of the bag penetrates through a through hole of a connecting part 102 and a base 101, and the exposed corner part is cut off after the corner penetrates out; then, the remaining corner portions are turned outwards to the outer side of the connecting portion 102, and then the turning-outwards portions are fixed by using the locking ring 200, namely, the locking ring 200 is sleeved on the connecting portion 102, the turning-outwards portions are fixed on the connecting portion 102 under the locking of the locking ring 200, and the turning-outwards portions are locked by the locking ring 200 and cannot be separated from the connecting portion 102 because the base 101 is arranged at the lower portion of the connecting portion 102; finally, the locking ring 200 is fixed by the sealing cover 300, thereby completing the sealing of the bag. The sealing device has good sealing air tightness, can be easily opened after sealing, does not damage the structure of the bag body, is very convenient for daily use, and has strong practicability and applicability; the sealing device is small in size, convenient to carry, high in sealing speed, environment-friendly and practical, and sealing can be completed without power equipment; the sealing device can be made of environment-friendly plastics, metals, wood and other materials, so that the cost is low; in addition, this closing device still has easy operation, and the bag solid particle thing trafficability characteristic is good, advantage that can used repeatedly.

In this embodiment, the connecting portion 102 has a hollow tubular structure, the base 101 has an annular structure disposed along the circumferential direction of the connecting portion 102, and the base 101 is disposed at one end of the connecting portion 102.

The base 101 is disposed at one side of the connecting portion 102 and is fixedly connected to the connecting portion 102, the base 101 is designed to limit the locking ring 200, when in use, the locking ring 200 is sleeved on the connecting portion 102 to fix the everted portion of the bag, and the base 101 is disposed at the bottom of the connecting portion 102 to prevent the locking ring 200 from falling off. The base 101 is designed to have a ring-shaped structure so that there is no corner when mounting or dismounting the base, which enhances comfort, and the circular base 101 is also adapted to the shape of the port of the locking ring 200 because the port of the locking ring 200 has a ring shape.

In this embodiment, the diameter of the base 101 is greater than or equal to the diameter of the locking ring 200.

In use, after the locking ring 200 fixes the everted portion of the bag, the front end of the locking ring 200 is closely attached to one side of the base 101, and the reason why the diameter of the base 101 is greater than or equal to the diameter of the locking ring 200 is to prevent the locking ring 200 from being separated from the connecting portion 102, thereby further enhancing the stability of the closure.

In the present embodiment, the inner height of the securing ring 200 is the same as the height of the connecting part 102, and the inner height of the closure cap 300 is the same as the outer height of the securing ring 200.

The locking ring 200 and the connecting portion 102 are set to the same height, so that when the locking ring 200 is fitted on the connecting portion 102 during use, the gap between the two is reduced, the airtightness is enhanced, and a better sealing effect is achieved.

In the present embodiment, the diameter of the securing ring 200 is adapted to the connecting portion 102, and the diameter of the seal cover 300 is adapted to the securing ring 200.

Under the condition that the sizes of the locking ring 200 and the connecting part 102 are matched with each other, when the bag is used, the outward turning part of the bag body is fixed, so that the connection between the locking ring 200 and the connecting part 102 is more fit and tighter; in the same way, under the condition that the sizes of the locking ring 200 and the sealing cover body 300 are matched with each other, when the sealing device is used, the locking ring 200 and the sealing cover body 300 are connected more closely, and the air tightness of the whole sealing device is better.

In this embodiment, the locking ring 200 has an inner annular surface 202 and an outer annular surface 201, and both the inner annular surface 202 and the outer annular surface 201 are provided with threads. An external thread 103 is formed on the outer side of the connection part 102 to be screwed with the inner circumferential surface 202 of the locking ring 200, an internal thread 302 is formed on the inner side of the closure lid body 300 to be screwed with the outer circumferential surface 201 of the locking ring 200, the locking ring 200 is screwed with the connection part 102, and the closure lid body 300 is screwed with the locking ring 200.

In use, the inner circumferential surface 202 of the locking ring 200 is provided with threads, and the outer side of the connecting portion 102 is provided with external threads 103 matching the threads of the inner circumferential surface 202 of the locking ring 200, so that the locking ring 200 and the connecting portion 102 can be in threaded connection, and when the locking ring 200 fixes the bag inside-out part, the locking ring 200 can firmly fix the bag inside-out part under the action of the threads.

When in use, the outer ring surface 201 of the locking ring 200 is provided with threads, and the inner wall of the sealing cover body 300 is provided with inner threads 302 matched with the threads of the outer ring surface 201 of the locking ring 200, so that the locking ring 200 and the sealing cover body 300 can realize threaded connection, after the locking ring 200 fixes the outward turning part of the bag, the sealing cover body 300 is sleeved on the locking ring 200, and then the sealing cover body 300 is screwed in a preset direction, thus completing the sealing. The locking ring 200 is screwed with the closure cap 300, so that the locking ring 200 and the coupling assembly 100 can be fixed. When this closing device is opened to needs, only need rotate along opposite direction of predetermineeing, can seal lid 300 in order to open to realize this closing device's used repeatedly, practice thrift the cost more, convenient operation, simple does not need extra equipment moreover, and the hand machine can accomplish and seal, practices thrift the environmental protection more, also has the practicality more.

In this embodiment, a groove 301 is formed on the inner wall of the sealing cover 300, and the extending direction of the groove 301 is the same as the opening direction of the sealing cover 300.

The groove 301 is rectangular and is vertically arranged along the inner wall of the sealing cover 300, and the groove 301 is arranged to make the gas in the bottle diffuse out along with the groove 301 when the sealing device is opened, so that the sealing cover 300 is more easily opened. It should be noted here that although the groove 301 is provided in the closure lid 300, the airtightness of the entire closure device is not affected.
