Description

Technical Field

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

[0002] A beer keg is a device for holding beer in the prior art, which generally includes a barrel body and a beer spear arranged at the barrel mouth of the barrel body and having a liquid outlet channel. The beer spear is provided with a wine guide tube connected to the cavity in the barrel body, and an aeration device connected to the cavity in the barrel body is provided outside the barrel body. When in use, air is ventilated into the barrel body through the aeration device (in layman's terms, it can be understood as an air pump), so that the beer is pressed out from the wine guide tube under the action of pressure. The user only needs to control the opening and closing of the faucet installed on the beer spear to achieve beer drawing.

[0003] In the above context, in order to reduce the cost of the entire set of equipment, the existing technology often replaces the original pumping device with a gas cylinder filled with carbon dioxide gas. Specifically, a connecting bracket is generally injection-molded at the bottom of the wine spear, and the gas cylinder is connected to the connecting bracket. After the wine spear and the barrel body are assembled, the gas cylinder is also installed in the barrel body. When in use, it is only necessary to control the opening or closing of the gas path of the gas cylinder through the gas valve installed on the connecting bracket to achieve wine drawing.

[0004] Although the above device solves the cost problem of the equipment, it still has certain defects. Although it can ensure the connection strength of the connecting bracket, the connecting bracket will still be damaged due to bumps during the installation process. Since the wine spear and the connecting bracket are an integrated structure, they need to be replaced together, and the replacement cost is relatively high. Summary of the Invention

[0005] The purpose of the present invention is to solve the above problems in the existing technology and propose a gas cylinder connection structure for a beer barrel. The technical problem to be solved by the present invention is: how to reduce the replacement cost.

[0006] The objectives of the present utility model can be achieved through the following technical solutions: a gas cylinder connection structure for a beer keg, the beer keg including a beer spear with a fixed cover connected to the bottom, the gas cylinder connection structure including a connecting bracket, characterized in that the bottom of the beer spear also has a connecting column, the connecting bracket has an annular sleeve portion, the outer wall of the sleeve portion has a lug plate, the sleeve portion is sleeved outside the fixed cover and the lug plate is positioned opposite to the connecting column, the gas cylinder connection structure also includes a fastener, the fastener passes through the lug plate and is screwed to the connecting column and presses the lug plate onto the connecting column.

[0007] The difference between the gas cylinder connection structure of the present beer keg and the prior art is that: as the installation structure of the gas cylinder, the connecting bracket is assembled with the beer spear in a detachable manner. Specifically, the connecting bracket is sleeved on the outside of the fixed cover at the bottom of the beer spear through the sleeve portion, and the support ear plate outside the sleeve portion and the connecting column at the bottom of the beer spear are relative to each other. The fasteners pass through the through holes on the support ear plate and are screwed into the threaded holes on the connecting column, so that the fasteners and the connection cooperate to clamp the support ear plate, thereby ensuring that the connecting bracket can be firmly positioned on the beer spear, that is, ensuring its subsequent installation stability for the gas cylinder. The advantage of adopting this connection method is that under the premise of ensuring that the connection strength is not greatly reduced, if the connecting bracket is damaged due to bumps or other reasons, the connecting bracket can be removed from the beer spear and replaced separately, without having to replace it together with the beer spear, thereby achieving the purpose of reducing replacement costs.

[0008] The connecting bracket, a structure for mounting gas cylinders, comprises a plurality of lugs spaced circumferentially along the sleeve, and a plurality of connecting posts spaced around the fixed cover. The alignment of the lugs with the connecting posts, and their tightening with fasteners, ensures the stability of the sleeve connection, and thus the connection between the connecting bracket and the spear.

[0009] In the aforementioned beer barrel gas cylinder connection structure, each lug plate has an annular stopper edge on the side facing the beer spear, and the connecting post is inserted into the stopper edge. Before installing the fastener, the plug-in fit between the connecting post and the stopper edge ensures the initial positioning of the sleeve, thereby ensuring the convenience of subsequent fastener installation.

[0010] In the aforementioned gas cylinder connection structure for a beer keg, the sleeve portion has an annular rim along its inner circumference, and the fixed cover has an abutting rim along its outer circumference, with the annular rim abutting against the abutting rim. During installation, the annular rim limits the insertion depth of the sleeve portion. Furthermore, during subsequent use, the abutting engagement between the annular rim and the abutting rim ensures stable force on the connecting bracket, preventing shaking of the connecting bracket carrying the gas cylinder.

[0011] In the above-mentioned gas cylinder connection structure for beer kegs, the sleeve portion has a plurality of spaced reinforcing ribs along the inner circumference thereof, and the plurality of reinforcing ribs are integrally formed with the annular rim, thereby ensuring the structural strength of the annular rim.

[0012] Compared with the existing technology, the gas cylinder connection structure of the beer barrel has the following advantages:

[0013] The connecting bracket is sleeved on the outside of the fixed cover at the bottom of the wine spear through the sleeve part, and the connecting column at the bottom of the wine spear is pre-positioned by plugging and connecting with the limit edge on the outer wall of the sleeve part. A fastener is passed through the through-hole on the support ear plate and screwed and locked with the threaded hole on the connecting column. Under the premise of ensuring the stable connection between the connecting bracket and the wine spear, if the connecting bracket is subsequently bumped and damaged, the fastener can be unscrewed and the connecting bracket can be removed for replacement.

DETAILED DESCRIPTION

[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] like Figure 1 、 Figure 2 、 Figure 5 as well as Figure 6 As shown, in the gas cylinder connection structure of the beer barrel, the beer barrel includes a beer spear 1 and a barrel body 4. The beer spear 1 is installed at the barrel mouth of the barrel body 4 by screwing. A fixed cover 11 is installed at the bottom of the beer spear 1, which serves to protect the valve body in the beer spear 1. The gas cylinder connection structure includes a connecting bracket 2 and a plurality of fasteners 3. The fastener 3 is specifically a screw. As an alternative, it can also be a bolt. The connecting bracket 2 is specifically long and vertically arranged. The upper end is a ring-shaped sleeve portion 21, and the lower end is a mounting portion for mounting the gas cylinder and the valve.

[0023] Combine Figure 3 and Figure 4 The sleeve portion 21 is provided with an annular edge 212 along the circumferential direction, and the outer wall edge of the fixed cover 11 facing downward has a resting edge 111 along the circumferential direction. The connecting bracket 2 is sleeved on the outside of the fixed cover 11 through the sleeve portion 21 and the annular edge 212 is resting against the resting edge 111. A plurality of downwardly arranged connecting columns 12 are provided at the bottom of the wine spear 1 by injection molding. A threaded hole 121 is provided on the downwardly arranged end surface of each connecting column 12. The plurality of connecting columns 12 are arranged at intervals around the circumference of the fixed cover 11. It is worth mentioning that a plurality of reinforcing ribs 213 are arranged at intervals along the circumferential direction in the sleeve portion 21, and the plurality of reinforcing ribs 213 are injection molded integrally with the annular edge 212. The arrangement of these reinforcing ribs 213 ensures that the structural strength of the annular edge 212 is higher.

[0024] A plurality of lug plates 211 are integrally formed by injection molding on the outer wall of the sleeve portion 21. Each lug plate 211 is provided with a through-hole 2111. The lug plates 211 are spaced apart along the circumference of the sleeve portion 21. When the sleeve portion 21 is sleeved on the outside of the fixed cover 11, the position of each lug plate 211 corresponds to the position of each connecting column 12. As a further solution, a limit edge 2112 is provided around the through-hole 2111 on the side surface of each lug plate 211 facing the bottom wall of the wine spear 1. During the process, when the sleeve portion 21 is sleeved on the outside of the fixed cover 11 and the annular edge 212 is abutted against the abutting edge 111, each connecting column 12 can be plugged into each limiting edge 2112 one by one and abut against the plate surface of the support ear plate 211, thereby achieving pre-positioning of the connecting bracket 2, preventing the connecting bracket 2 from rotating during the subsequent installation process, resulting in deviation between the positions of the threaded holes 121 and the through holes 2111. Then, it is only necessary to install the fastener 3 and press the support ear plate 211 onto the connecting column 12 through the fastener 3.

[0025] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.

[0026] Although this document frequently uses terms such as the wine spear 1, fixed cover 11, abutment edge 111, connecting post 12, threaded post 121, connecting bracket 2, sleeve portion 21, support lug 211, perforation 2111, limiting edge 2112, annular edge 212, reinforcing rib 213, fastener 3, and barrel body 4, the use of other terms is not excluded. These terms are used solely to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitations is contrary to the spirit of the present invention.
