Description

Anti-pinch door automatic closing hydraulic hinge

This creation is about a hydraulic hinge, especially an anti-pinch door automatic closing hydraulic hinge.

Press, the hinge that is usually installed on the door, only used as a pivotal connection between the door frame and the door panel. After the door panel is pushed open, it must be pushed back and closed by human power. However, the conventional hinge has an automatic return function, and most of them are utilized. The spring acts directly on the hinge and has no cushioning design and positioning function, which is easy to cause damage to the mechanism. The existing hinge has a design buffer mechanism, and the friction mechanism or the pneumatic mechanism is used, and the design complexity is high, and in some occasions, the door panel must be automatically opened and closed after being pushed open, such as a sanitary compartment in a public place, so that the manufacturer develops. In the patent "No. 91204090", "Hinge Structure Improvement", as shown in FIG. 1, the hinge 1 is composed of an upper plate A11, a lower plate A12 and a pivot A13.

When the hinge 1 of the conventional hinge is implemented, please refer to FIG. 1 , the flaps A11 and A121 of the upper plate A11 and the lower plate A12 are respectively locked on the door leaf and the partition wall by screwing elements, and The side of the door leaf is fixed to the wall of the compartment; when the door leaf is pushed open, the annular inclined surface A113 of the cylinder A112 of the upper door A11 is moved upward by the cam surface A131 of the pivot A13, and When the door leaf is opened, the annular inclined surface of the upper plate piece A11 can be moved downward by the cam surface A131 of the pivot A13 by the weight of the door leaf itself, so that the door leaf can be automatically closed.

However, the conventional hinge A1 is constructed by the above, and although the purpose of automatically returning the door leaf can be achieved, since the positioning sleeve A122 of the cylinder A112, the pivot A13 and the lower plate A12 are made of plastic, and the cylinder The A112 and the upper plate door A11 and the positioning sleeve A122 and the lower plate A12 are tightly coupled to each other to have a good combination, but the cylinder A112 and the upper plate When the sheet A11 is combined, or excessively squeezed, the cylinder A112 is deformed, and the cam surface A131 of the pivot A13 is also deformed along with it. Similarly, the positioning sleeve A122 is combined with the lower plate A12. When excessively squeezing, the positioning sleeve A122 is deformed, so that the tooth portion A132 and the tooth groove A123 are not well matched, thereby causing the assembly A112 and the pivot A13 and the positioning sleeve A122 and the pivot A13 to lose precision. , which affects the smoothness of the door closing and the accuracy of the door angle adjustment. In addition, the upper door A11 is only engaged with the pivot A13 by the cylinder A112, and the door can be removed by lifting up, which is easy to cause the risk of the door leaf being stolen.

Therefore, how to improve the precision of the hinge of the hinge and avoid the theft of the door leaf is the direction that the relevant manufacturers engaged in the industry are eager to study and improve, in order to meet the user's use needs.

Therefore, in view of the above problems and deficiencies, the creators have collected relevant information, and through multi-party assessments and considerations, and through years of experience in the industry, through continuous trials and revisions, they have designed such anti-pinch tips. The birth of the patent for the creation of automatic closing hydraulic hinges.

The second purpose of the present invention is to provide an anti-pinch automatic door closing hydraulic hinge. When the door leaf and the door frame are non-parallel, the piston module and the brake module are forced to rotate at the bottom end of the piston module. The positioning pin moves downward from the spiral groove of the brake module, and the upper and lower fins can be rotated to a parallel angle, thereby generating the function of automatically homing and closing the door.

Another object of the present invention is to provide an anti-pinch automatic closing hydraulic hinge, which is designed to improve the buffering hinge of the conventional air pressure control. It can produce a leak and cause a reduction in buffering effect.

The anti-pinch automatic closing hydraulic-type hinge capable of achieving the above-mentioned novel purpose comprises at least a body having a movable mechanism and a positioning mechanism, the movable mechanism having an upper wing and a hollow pipe a piston module is disposed, and a control component is disposed at a top end of the hollow tube portion; the positioning mechanism is provided with a lower wing piece and an accommodating space for placing a brake module, and the top side of the positioning mechanism forms at least one strip shape a groove for limiting the movement range of the positioning pin of the piston module, the screw module is further provided with a spiral groove; and a set of rings is disposed between the movable mechanism and the positioning mechanism.
