Description

Technical Field

[0001] The utility model relates to the technical field of sealing and storing Chinese herbal medicines, in particular to a sealing and storing device for Chinese herbal medicines. Background Art

[0002] Sealed jars are one of the commonly used devices for sealing and storing Chinese herbal medicines. Sealed jars are containers made of glass, plastic, ceramics and other materials. Sealed jars include a jar body and a jar cover. A sealing ring is sleeved at the bottom edge of the jar cover. When the jar cover is closed, the sealing ring fits tightly against the inner wall of the jar body, which can achieve good sealing storage.

[0003] There are many kinds of sealed cans, among which there is a large-diameter sealed can, which allows the hand to be fully inserted into the can body to take and place Chinese herbal medicines. Due to its large-diameter structure, the friction between the sealing ring and the can body is large. When opening the can lid, a large force is required to complete the opening of the can lid. The can body itself is large and cannot be grasped. The can body can only be supported by one hand and then the can lid is opened with a large force. However, when the can lid is separated from the can body, the operator is likely to push the can body, causing the can body to shift. In severe cases, the can body may shift out of the table, causing the medicinal materials to scatter. Based on this, a Chinese herbal medicine sealing and storage device is provided.

[0017] The connecting air pipe is symmetrically fixed on the inner side of the annular airbag and communicated with the inner cavity of the annular airbag. The connecting air pipe passes through the through hole and is connected to the exhaust pipe. The compressed air inside the annular airbag is discharged outward through the channel composed of the connecting air pipe, the exhaust pipe and the exhaust hole, so as to reduce the extrusion force on the sealing strip.

[0018] As a further solution of the utility model: the outer wall diameter of the annular airbag in the initial state is larger than the inner wall diameter of the large-diameter tank, and the bottom of the annular airbag is a conical surface;

[0019] A plurality of sealing strips are evenly arranged along the vertical direction.

[0020] As a further solution of the utility model: a sealing gasket is sleeved on the outer side of the threaded cylinder, and the sealing gasket is located at the bottom of the blocking threaded cylinder and is used to seal between the blocking threaded cylinder and the threaded cylinder.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] By setting up a sealing assembly, a good seal between the cover assembly and the large-diameter tank body is achieved. At the same time, the sealing threaded tube is moved upward to release the blockage of the exhaust hole, so that the compressed air inside the annular airbag is discharged, and the inside of the annular airbag is restored to normal pressure. At this time, the squeezing force between the sealing strip and the inner wall of the large-diameter tank body is reduced. After that, the cover assembly can be easily pulled up as a whole by simply pulling the spherical block upward. Compared with the traditional operation method, it is not only easier, but also can effectively prevent the large-diameter tank body from deflecting, tipping, etc. due to uneven force.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figures 1 to 3 In the embodiment of the utility model, a Chinese herbal medicine sealing and storage device comprises a large-caliber tank body 1 and a cover body assembly 2, wherein the cover body assembly 2 comprises a tank cover 201, a docking ring 202, a threaded cylinder 204, a plugging threaded cylinder 205, and a spherical block 206;

[0029] The docking ring 202 is fixed to the bottom of the tank cover 201, and an annular groove 203 is provided on the outer side of the docking ring 202. The threaded cylinder 204 is fixed to the center of the top of the tank cover 201. The plugging threaded cylinder 205 is threadedly connected to the outer side of the threaded cylinder 204. The spherical block 206 is fixed to the top of the plugging threaded cylinder 205, and is used to take the tank cover 201.

[0030] A sealing assembly 3 is provided on the outside of the docking ring 202, and the sealing assembly 3 is used to achieve sealing between the docking ring 202 and the inner wall of the large-diameter tank body 1. The sealing assembly 3 includes a sealing unit and a drag reduction unit. The sealing unit is used to achieve sealing operation between the docking ring 202 and the large-diameter tank body 1, and the drag reduction unit is used to reduce the friction resistance between the sealing unit and the inner wall of the large-diameter tank body 1, so as to facilitate the opening operation of the tank cover 201;

[0031] The sealing unit includes an annular airbag 301, an annular clamping strip 302, and a sealing strip 303:

[0032] The annular clamping strip 302 is integrally formed on the inner side of the annular airbag 301, and the annular airbag 301 is sleeved on the outer side of the docking ring 202. The annular clamping strip 302 is clamped on the inner side of the annular clamping groove 203 to provide a limiting force for the installation of the annular airbag 301. The sealing strip 303 is integrally formed on the outer side of the annular airbag 301. When the docking ring 202 is plugged into the inner side of the large-diameter tank body 1, the sealing strip 303 and the annular airbag 301 are deformed and contracted. The contraction of the annular airbag 301 increases the internal pressure, and a reverse force is generated to make the sealing strip 303 closely fit the inner side of the large-diameter tank body 1, thereby achieving sealing between the docking ring 202 and the large-diameter tank body 1.

[0033] The drag reduction unit includes a connecting air pipe 304, an exhaust pipe 305, and an exhaust hole 306;

[0034] The exhaust pipe 305 is fixed to the bottom of the tank cover 201 and penetrates the tank cover 201 and communicates with the inner cavity of the threaded cylinder 204. The exhaust hole 306 is opened on the side of the inner wall of the threaded cylinder 204 and penetrates to the outside of the threaded cylinder 204.

[0035] A through hole 207 is symmetrically formed on the inner side of the docking ring 202 and extends to the outer side of the docking ring 202;

[0036] The connecting air pipe 304 is symmetrically fixed on the inner side of the annular airbag 301 and is connected to the inner cavity of the annular airbag 301. The connecting air pipe 304 passes through the through hole 207 and is connected to the exhaust pipe 305. The compressed air inside the annular airbag 301 is discharged outward through the channel formed by the connecting air pipe 304, the exhaust pipe 305 and the exhaust hole 306, so as to reduce the extrusion force on the sealing strip 303.

[0037] In this embodiment: the large diameter of the large-diameter tank body 1 makes it easy for the user to put his hand into the large-diameter tank body 1 to place or take out the Chinese herbal medicine. When covering the large-diameter tank body 1, it is only necessary to hold the spherical block 206 to cover the cover assembly 2 on the top of the large-diameter tank body 1. During this process, when the docking ring 202 is inserted into the large-diameter tank body 1, the sealing strip 303 and the annular airbag 301 are in contact with the inner wall of the large-diameter tank body 1 and deformed by force. The sealing strip 303 is forced to bend upward, and the annular airbag 301 is forced to shrink and the air inside is compressed (it should be noted that at this time, the sealing threaded cylinder 205 and the threaded cylinder 204 are in a completely tightened state, that is, at this time, the sealing threaded cylinder 205 blocks the exhaust hole 306, which is used to disconnect the inner cavity of the annular airbag 301 from the external space);

[0038] The compressed air will provide a reverse thrust to the sealing strip 303, so that the sealing strip 303 is closely attached to the inner wall of the large-diameter tank body 1, thereby ensuring the sealing of the cover assembly 1 and the large-diameter tank body 1, and providing a good sealing environment for the storage of Chinese herbal medicines;

[0039] When you need to take Chinese herbal medicine, the steps are as follows:

[0040] First, the spherical block 206 is rotated, and the spherical block 206 drives the plugging threaded cylinder 205 to rotate, so that the plugging threaded cylinder 205 and the threaded cylinder column 204 are loosened, and the plugging threaded cylinder 205 will move upward. When the plugging threaded cylinder 205 moves up to the misalignment with the exhaust hole 306, it can stop. At this time, the compressed air in the annular airbag 301 is discharged through the channel composed of the connecting air pipe 304, the exhaust pipe 305, and the exhaust hole 306. The inside of the annular airbag 301 returns to normal pressure. At this time, the squeezing force between the sealing strip 303 and the inner wall of the large-diameter tank body 1 is reduced. After that, only the spherical block 206 needs to be pulled upward to easily pull the cover assembly 2 upward as a whole, and then the cover assembly 2 can be conveniently opened. Compared with the traditional operation method, it is not only easier, but also can effectively prevent the large-diameter tank body 1 from deflecting or tipping due to uneven force.

[0041] It should be additionally explained that: after the cover assembly 2 is separated from the large-diameter tank body 1, the annular airbag 301 and the sealing strip 303 will be reset under the action of their own elasticity, and then the sealing threaded cylinder 205 can be tightened to perform the secondary covering operation.

[0042] Please refer to Figures 1 to 3 , the outer wall diameter of the annular airbag 301 in the initial state is larger than the inner wall diameter of the large-diameter tank body 1, and the bottom of the annular airbag 301 is a conical surface;

[0043] A plurality of sealing strips 303 are evenly arranged along the vertical direction.

[0044] In this embodiment: this structure enables the annular airbag 301 and the sealing strip 303 to be fully deformed when in contact with the inner wall of the large-diameter tank body 1, thereby providing sufficient squeezing force for sealing;

[0045] Multiple sealing surfaces are realized by multiple sealing strips 303, thereby achieving a good sealing effect.

[0046] Please refer to Figures 1 to 3 A sealing gasket 208 is sleeved on the outer side of the threaded cylinder 204 . The sealing gasket 208 is located at the bottom of the plugging threaded cylinder 205 and is used to seal between the plugging threaded cylinder 205 and the threaded cylinder 204 .

[0047] In this embodiment: when the sealing threaded barrel 205 and the threaded column 204 are tightened, the sealing threaded barrel 205 will squeeze the sealing gasket 208, and the sealing gasket 208 will deform to fill the gap between the sealing threaded barrel 205 and the threaded column 204 and between the sealing threaded barrel 205 and the tank cover 201, thereby ensuring that the sealing threaded barrel 205 seals the exhaust hole 306.

[0048] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
