Description

Technical Field

[0001] The utility model belongs to the technical field of beverage barrels and relates to a gas cylinder connection structure of a beverage barrel. Background Art

[0002] A beverage barrel refers to a container for holding a large amount of beverages, such as water, juice or beer. The capacity of beverage barrels varies from several liters to dozens of liters, and generally a faucet is provided for pouring out beverages.

[0003] For existing beverage barrels, for example, a kind of wine barrel wine outlet structure is disclosed in Chinese patent literature [Patent No.: 202322350292.9; Application Publication No.: CN220703226U]. The wine barrel includes a barrel body. The wine outlet structure includes a wine spear with a wine outlet channel provided at the barrel mouth of the barrel body. A gas cylinder connected to the wine spear is provided in the barrel body. A wine outlet pipe communicating with the wine outlet channel is provided beside the gas cylinder. The upper end of the wine outlet pipe is connected to the wine spear through a plug-in member, and the lower end of the wine outlet pipe extends to the bottom of the barrel body and is connected to the gas cylinder through a clamping member.

[0004] For the wine barrel of this structure, a gas cylinder is provided in the barrel body. The gas cylinder is an aluminum gas cylinder. The top of the gas cylinder has an elastic snap ring. The wine spear includes a pressure regulating upper cover with a limit card slot therein. During installation, the elastic snap ring is embedded into the pressure regulating upper cover, and a certain external force is applied to make the elastic snap ring first contract inward and then expand outward elastically to reset, so that the elastic snap ring is embedded in the limit card slot, and the gas cylinder is clamped and positioned with the pressure regulating upper cover, and the gas cylinder is positioned in the barrel body. However, for the wine barrel of this structure, since the gas cylinder is an aluminum gas cylinder and has a certain elasticity, but it is positioned by an elastic clamping method, the positioning strength is low and the stability is poor, and the problem of the gas cylinder falling off exists. Moreover, the elastic snap ring is a part of the gas cylinder structure. When the elastic snap ring elastically contracts and expands, the internal volume of the gas cylinder will change slightly, which will affect the gas stability inside the gas cylinder to a certain extent. Summary of the Invention

[0005] The purpose of the utility model is to solve the above problems existing in the prior art, and propose a gas cylinder connection structure of a beverage barrel, and the technical problem to be solved is how to improve the installation stability of the gas cylinder.

[0006] The purpose of the utility model can be realized by the following technical solutions: A gas cylinder connection structure of a beverage barrel, the beverage barrel includes a barrel body and a wine spear. The wine spear and the gas cylinder are both provided in the barrel body. The connection structure is characterized in that the connection structure includes a bottle cap. The inner side wall of the bottle cap has an internal thread, the bottle mouth of the gas cylinder has an external thread, the gas cylinder is fixedly connected to the bottle cap by thread, and the bottle cap is rigidly clamped and positioned with the wine spear.

[0007] This gas cylinder is first integrated with the bottle cap through a threaded connection, and then the bottle cap is inserted into the spear, so that the bottle cap is clamped and positioned with the spear, thereby installing and positioning the gas cylinder in the barrel. The clamping and positioning of the bottle cap and the spear is a rigid clamping and positioning, which ensures that the gas cylinder will not fall off after installation, improves the stability of the gas cylinder installation, and at the same time, during the installation process, the internal volume of the gas cylinder will not be changed, making the gas inside the gas cylinder stable.

[0008] In the above gas cylinder connection structure of a beverage barrel, the bottle cap has a protruding abutting portion facing inward, and a sealing ring is embedded in the abutting portion. When the gas cylinder is threadedly locked with the bottle cap, the end face of the bottle mouth presses the sealing ring in the abutting portion.

[0009] In the above gas cylinder connection structure of a beverage barrel, the circumferential outer side wall of the bottle mouth has an outwardly protruding annular stop edge, and the opening of the bottle cap has an annular step groove. When the gas cylinder is threadedly locked with the bottle cap, the stop edge is embedded in the step groove. The stop edge and the step groove play a role in limiting the relative position of the gas cylinder and the bottle cap, and also play a role in blocking, preventing the beverage in the barrel from easily entering the threaded part.

[0010] In the above gas cylinder connection structure of a beverage barrel, several limiting pieces are fixedly connected in the spear, and the outer side wall of the bottle cap has a limiting surface. When the gas cylinder is threadedly locked with the bottle cap, the limiting pieces can abut against the limiting surface. The limiting pieces and the limiting surface play a role in limiting the relative position of the spear and the bottle cap, ensuring that the bottle cap is installed in place, thereby improving the stability of the gas cylinder installation.

[0011] In the above gas cylinder connection structure of a beverage barrel, the circumferential outer side wall of the bottle cap has an annular first clamping groove, and the spear has an annular first clamping strip. The first clamping strip is embedded in the first clamping groove to clamp and position the bottle cap and the spear. In this structure, the clamping and positioning of the bottle cap and the spear is a rigid clamping and positioning, which ensures that the gas cylinder will not fall off after installation, improves the stability of the gas cylinder installation, and at the same time, during the installation process, the internal volume of the gas cylinder will not be changed, making the gas inside the gas cylinder stable.

[0012] As another case, in the gas cylinder connection structure of a beverage barrel described above, a first annular clamping strip is provided on the circumferential outer side wall of the bottle cap, and a first clamping groove is provided in the lance in an annular shape. The first clamping strip is embedded into the first clamping groove to positionally fix the bottle cap and the lance. With this structure, the positional fixation of the bottle cap and the lance is a rigid clamping fixation, preventing the gas cylinder from falling off after installation, improving the stability of the gas cylinder installation. At the same time, during the installation process, the internal volume of the gas cylinder will not be changed, keeping the gas inside the gas cylinder stable.

[0013] In the gas cylinder connection structure of a beverage barrel described above, the bottle cap includes a bottom plate and an annular cover body. The internal thread is located on the inner side wall of the cover body. The circumferential edge of the bottom plate has a second annular clamping groove, and one end of the cover body has a second annular clamping strip. The second clamping strip is embedded and positioned in the second clamping groove to fixedly connect the bottom plate and the cover body. An air outlet valve is fixedly connected through the bottom plate. With this structure, the strength at the air outlet valve is ensured, preventing the gas cylinder from shaking when discharging gas, improving the stability when the gas cylinder discharges gas, and thus enhancing the stability of the gas cylinder installation.

[0014] In the gas cylinder connection structure of a beverage barrel described above, the gas cylinder is made of plastic material, the cover body is made of plastic material, and the bottom plate is made of aluminum. The gas cylinder and the bottle cap are fixedly connected by means of threaded connection, enabling stable installation of the gas cylinder even when the gas cylinder is made of plastic material such as PET, improving the stability of the gas cylinder installation.

[0015] Compared with the prior art, the gas cylinder connection structure of a beverage barrel provided by the present utility model has the following advantages:

[0016] 1. First, the gas cylinder is integrated with the bottle cap by means of threaded connection, and then the bottle cap and the lance are positioned by means of rigid clamping fixation, preventing the gas cylinder from falling off after installation, improving the stability of the gas cylinder installation. At the same time, during the installation process, the internal volume of the gas cylinder will not be changed, keeping the gas inside the gas cylinder stable.

[0017] 2. Both the gas cylinder and the cover body are made of plastic material, enabling the gas cylinder and the bottle cap to be fixedly connected by means of threaded connection, and also achieving stable installation of the gas cylinder, improving the stability of the gas cylinder installation.
