Technical Field

The utility model belongs to the technical field of drink equipment, a wine post is related to.

Background

Beer is a common alcoholic beverage in the present life, and is a beverage with the third consumption after water and tea in the world, the existing beer production process is generally divided into three parts of malt manufacturing, brewing and canning, and the specific steps are that after malt, rice and other raw materials are crushed, a series of processes of saccharification, fermentation, filtration and the like are carried out, and the produced liquor is poured into a wine barrel made of materials such as aluminum, stainless steel and the like for storage.

When the wine needs to be drunk or bottled, the wine needs to be led out from the wine barrel to a cup or a wine bottle; among the prior art, can be drawn smoothly for guaranteeing wine liquid, generally can install a tap additional on the wine post, install a wine pipe in the wine post, go out the integrated pressure pipe of one end of wine pipe, the tap is installed on the lateral wall of cask, the articulated handle of pressing on its lateral wall, internally mounted has the pressing piece of being connected with the handle, the one end that goes out the wine pipe and have the pressing pipe sets firmly in the tap, the other end passes the tap and stretches into the wine post, follow-up through pressing the handle drive pressing piece extrusion pressing pipe, thereby make wine liquid by a wine pipe suction and flow through pressing the pipe.

After the wine post is used, the user needs in time to wash the wine pipe to guarantee wine pipe health, avoid remaining for a long time the wine stain in the wine post bad, nevertheless go out wine pipe direct integration in the wine post, it is inconvenient to wash it, and wash the inside cleanliness factor of back wine pipe and also can't obtain effective assurance, thereby cause follow-up wine liquid that flows out by going out wine pipe and can't reach the hygienic standard.

Disclosure of Invention

The utility model aims at having the above-mentioned problem to current technique, provided a wine post, the utility model aims to solve the technical problem that: how to conveniently replace the wine pipe to ensure the sanitation of the wine.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a wine column, includes the cylinder that both ends run through, install the tap on the outer wall of cylinder top, its characterized in that, this wine column still includes plastics wine pipe, plastics wine pipe one end is connected with out the wine pipe, go out the wine pipe with the connection can be dismantled to the tap, just the tap can be controlled it opens and close to go out the wine pipe, the other end of plastics wine pipe passes from top to bottom the cylinder, just the plastics wine pipe passes the one end of cylinder is connected with and is used for the joint be connected with the distributor.

This wine post includes the cylinder that both ends run through, the tap is installed in the top department of cylinder, this wine post still includes a plastics wine pipe, the play wine pipe and the tap demountable installation of the one end of plastics wine pipe, the other end passes the cylinder downwards and connects and can be connected with the distributor, therefore, only need to install the wine pipe in the tap when the installation, plastics wine pipe is thrown down by the cylinder upper end, make this end of plastics wine pipe can freely fall and pass the cylinder, when dismantling plastics wine pipe, only need to go out wine pipe and pull down on by the tap, and take out plastics wine pipe by in the cylinder can, in view of easy dismounting, consequently this plastics wine pipe can adopt disposable wine pipe, thereby can change after the use, need not to wash, the sanitary degree of convenient operation and assurance wine.

In the wine column, one end of the plastic wine pipe, which is provided with the joint, is provided with a plurality of balancing weights, and the balancing weights are sleeved outside the plastic wine pipe and are positioned above the joint.

Go out the wine pipe and install a plurality of balancing weights with the one end that connects, the balancing weight specifically cup joints outside a wine pipe and is located the top that connects, the user is when assembling, can directly stretch into the wine post with plastics wine pipe in, make plastics wine pipe through the balancing weight of self lower extreme fall through the effect of gravity, make the lower extreme of plastics wine pipe stretch out the cylinder bottom and be connected with the distributor on the cask owing to the gravity of balancing weight, thereby need not the user and carry out manual adjustment to the lower extreme of plastics wine pipe when the assembly, guarantee the convenience of plastics wine pipe installation from this.

In foretell wine column, go out the wine pipe including the top tube and the low tube that cup joint mutually, the top tube can relative movement with the low tube realize opening and close, be equipped with the pressing part that is used for driving the top tube and pushes down in the tap, it has the handle that can drive the pressing part and push down to articulate on the tap outer wall, the draw-in groove that is used for the joint top tube is offered to the pressing part front end, the draw-in groove runs through the preceding terminal surface of pressing part, tap front end is located the mounting groove that is used for the joint low tube is offered to the draw-in groove below, the mounting groove runs through the preceding terminal surface of tap, just be equipped with the retaining member that is used for cramping the low tube in the mounting groove.

The wine column comprises a tap, a plastic wine pipe, a pressing piece, a handle, a wine outlet hole and a wine outlet hole, wherein the pressing piece is arranged in the tap, the handle can be pulled by a user after an upper pipe and a lower pipe which form the wine pipe are arranged in the tap, so that the pressing piece is pressed downwards by the handle, the upper pipe and the lower pipe can move relatively at the moment, the wine outlet hole is exposed, and wine in the wine column can flow into the upper pipe and the lower pipe from the plastic wine pipe in sequence and then flow out of the outside, so that the convenience in wine taking is ensured; the front end of the pressing piece is provided with a clamping groove, the clamping groove penetrates through the front end face of the pressing piece, the front end of the faucet is provided with a mounting groove, the mounting groove penetrates through the front end face of the faucet, when the faucet is assembled, a user can clamp an upper pipe in the clamping groove and clamp a lower pipe in the mounting groove, and the mounting groove is located below the clamping groove, so that the upper pipe and the lower pipe cannot be bent after being sleeved, in addition, a locking piece is arranged in the mounting groove, and the locking piece can clamp the lower pipe after being arranged in the mounting groove, so that the lower pipe is positioned in an auxiliary manner, and the stability of the upper pipe and the lower pipe in the faucet is further ensured; when dismantling, the user can directly pull up top tube and low tube outwards for the low tube breaks away from the retaining member and deviates from the draw-in groove, the top tube deviates from the draw-in groove simultaneously, makes the wine pipe user can dismantle and change it after finishing using, guarantees the convenience of wine pipe dismouting from this.

In the wine column, the outer walls of the two sides of the faucet are provided with clamping grooves, and the wine column further comprises a sealing cover which is clamped in the clamping grooves and fixed on the faucet through fasteners.

The draw-in groove has been seted up on the both sides outer wall of tap, a closing cap is installed to joint inslot joint, and the closing cap after the joint installation passes through the fastener to be fixed on the tap, and the closing cap can protect plastics wine pipe and play wine pipe part that exposes outside, avoids in the use foreign object mistake to bump out wine pipe and plastics wine pipe and causes the damage, also can completely cut off the dust in the air, guarantees plastics wine pipe and goes out the cleanliness factor of wine pipe.
