Description

BACKGROUND OF THE INVENTION The present invention relates to a meohamle for clamping a container to a spray gun for spraying paints and other liquids.

The best known sseohanisis for clamping liquid containers to guns are bolted connections such that the lid of the container is usually firmly attached to the gun and is provided with an internal or external thread corresponding to the thread at the rim of the container.

A further known meohanism is bayonet closures formed either instead of the thread in the previously described embodiment, or independently of the lid, such that after the yoke has been folded by the projections on the container, by means of a screw.

With the first embodiment they will be carried out. it is particularly difficult and time-consuming to catch it! and tightening of the container, whereby particularly sticky and dried coatings make it very difficult to separate the container for filling.

Ion-closures, when tightening the bayonet independently of the rotation of the container with respect to the lid, eliminate the disadvantage of the pipe joints, but the design is disproportionately complex, and is susceptible to dirt from the paints for tightening the yoke.

These disadvantages are overcome by the mechanism according to the invention, which is based on the fact that the compression screw spring forming the lid of the can lid is firmly connected to the gun body as well as the canister attached to the gun.

The mecbaniemus of the invention allows 1 quick attachment of the can as closed can to the gun. The saol pipe of the pistol is then adapted to pierce the canned wolf - attached to the gun I again by pushing the wolf against the compression screw springs * and catching the canned bottom with a support fixed to the gun body.

The mechanism according to the invention allows simple and rapid clamping of the container, while the elimination of the screw connections eliminates any defects arising during the removal of the container.

A schematic illustration of an attached container is shown in FIG. 1.

The mechanism for clamping the canister and the pistol consists of a compression screw spring 1 attached to the pistol 2, to which is also attached a support J. Saol tube 4 has an inclined trimmed cone, provided with a cutting edge J5.

With the lid 6 of the closed container (canned) laid on a solid support *, approximately the center of the tube 4 is placed approximately on the center. By pushing the container against the gun 2, the compression spring 1 is compressed so that the container / can / can be grasped by the support 3. The compression spring 1 pushes the container against the support, while the saol tube h prevents the container (can) from slipping out and its release from clamping. Dismantling is obvious from the function of the mechanism. As for the open container connection, the saol tube is slid onto the salar tube 4 against the front of the wolf 6, pressed against the spring spring 1 and gripped with the bottom against the support. as when clamping a can.

The described arrangements are exemplary only and can be varied according to the requirements of the various spray guns. For example, the container support may be attached to the gun at the point of attachment of the spring.

The mechanism according to the invention reduces the downtime of the squeezing caused by the sensing, filling and refitting of the containers to a minimum. Using canned food Replacements can be made in seconds.
