Description

Technical Field

[0001] This utility model relates to the field of specimen bottle technology, specifically a sealing device for immersion specimen bottles. Background Technology

[0002] Currently, specimen bottles mainly prevent the evaporation of preservatives and the intrusion of external dust by using a frosted joint between the bottle body and the cap. The frosted texture inevitably creates a tiny gap between the bottle body and the cap. The soaking solutions currently used are mainly formalin and alcohol, both of which are highly volatile. This not only causes gas to escape, reducing the concentration of the soaking solution and decreasing the preservative effect, thus accelerating the deterioration of the specimen, but also, formalin has carcinogenic effects, and its volatilization can have adverse effects on the human body. Therefore, further sealing of the specimen bottle is particularly important.

[0003] Currently, methods for further sealing specimen bottles include traditional paraffin wax, plaster, and petroleum jelly. These sealing methods achieve a sealing effect by applying paraffin wax, plaster, or petroleum jelly to the connection between the stopper and the bottle mouth. However, they are difficult to fill the gap between the stopper and the bottle mouth and there is a risk of the stopper falling off or breaking, resulting in poor sealing performance. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a sealing device for immersion specimen bottles. To solve the above-mentioned technical problems, this utility model adopts the following technical solution:

[0006] The specimen bottle has an opening and a sealing assembly on its upper side, and a base at its bottom for supporting the specimen bottle. The sealing assembly includes a stopper and five sets of sealing rings. The sealing rings are evenly spaced on the surface of the stopper. The stopper is inserted into the opening of the bottle, and the sealing rings are used to seal the opening of the specimen bottle.

[0007] An inflation assembly includes a squeeze-type inflation ball, an inflation tube, and an air bladder. The air bladder is positioned between adjacent sealing rings. The squeeze-type inflation ball inflates the air bladder through the inflation tube. Once inflated, the air bladder fills the gap between the bottle stopper and the bottle opening, thereby further filling the gap between the bottle stopper and the bottle opening under the sealing effect of the sealing rings.

[0008] Preferably, the airbag is provided with an inflation port, and the bottle stopper is provided with a first inflation channel and a second inflation channel. The first inflation channel is connected to the inflation port, and the second inflation channel is connected to the inflation tube. The hand-squeezed inflatable ball inflates the airbag through the second inflation channel and the first inflation channel.

[0009] Preferably, an air-locking assembly is provided between the second inflation channel and the inflation tube. The air-locking assembly includes a fixing block, an inflation nozzle, an inflation hose, and a compression chamber. The compression chamber is located at the center of the fixing block. The inflation hose originates inside the compression chamber and is made of an elastic material. One end of the inflation hose is connected to the inflation nozzle, and the other end is connected to the second inflation channel. The inflation nozzle is placed on the upper surface of the fixing block, and the inflation tube is inserted into the inflation nozzle for inflation.

[0010] Preferably, two sets of push-pull rods are provided through both sides of the fixing block. The push-pull rods move horizontally within the fixing block. One end of the push-pull rod is provided with a push block. The reciprocating horizontal movement of the push block controls the opening and closing of the inflation hose. Thus, after the airbag is inflated, the push block closes the inflation hose. When it is necessary to open the bottle stopper, the push block slides outward to open the inflation hose, and gas is ejected from the inflation nozzle.

[0011] Preferably, the fixing block has a locking block on each side, the surface of the locking block has a locking groove, one end of the push rod has a pushing head, the upper and lower surfaces of the pushing head have elastic blocks, a telescopic spring is provided between the pushing head and the fixing block, the elastic block controls the opening and closing of the inflation hose by moving out and locking in the locking groove, when the inflation hose needs to be closed, the elastic block is locked in the locking groove, and the pushing block closes the inflation hose.

[0012] Beneficial effects: This utility model discloses a sealing device for immersion specimen bottles. The sealing ring on the surface of the bottle stopper is used to seal the bottle mouth of the specimen bottle. On this basis, an air bladder is set between the sealing rings, so that under the sealing effect of the sealing rings on the specimen bottle, the air bladder is further used to seal the gap between the bottle stopper and the bottle mouth of the specimen bottle, ensuring the airtightness of the specimen bottle. When it is necessary to close the inflation hose, the elastic block is engaged in the slot, and the pushing block closes the inflation hose to prevent the gas in the air bladder from escaping.
