This application is a continuation of International Application No. PCT/CN2018/114001, filed Nov. 5, 2018, which claims priority to Chinese Patent Application No. 201711436729.3, filed on Dec. 26, 2017, the entire contents of both of which are incorporated herein by reference.
The present disclosure relates to door body accessories and, more particularly, to a positionable hidden hydraulic hinge configured to connect a door leaf with a door frame.
The accessory that connects the door leaf with the door frame and that has an automatic door closing function is referred to as a door closer. Currently, the door closer used for a room door is often installed at the back of the room door, which is also referred to as an exposingly installed door closer, such as a damping hinge disclosed in patent number 201610744065 published by the Chinese national patent office. The disadvantages of such a door closer include: 1. not aesthetically pleasing, and tending to ruin the overall effect of the room door; 2. an exposed part of such type of a door closer has a safety risk for a child in the family; 3. the room door is often not fully closed due to design issues. On the other hand, traditional mechanical hinges, although installed in a hidden manner, cannot achieve the effect of gradual door closing, and do not have a positioning function. It is very inconvenient to use when the door cannot be positioned after being opened. In the current market, although some hydraulic hinges have a hydraulic buffer function, they are all designed for exposed installations, with the hydraulic part configured in a shaft, and the hinge shaft is relatively thick and large. Such a configuration not only has a complex structure, and a short lifetime, but also affects the aesthetics of the door and does not provide a certain degree of fire retardance.
The main technical issue to be addressed by the present disclosure is, to provide a positionable hidden hydraulic hinge, which has a simple structure, and is safe to use.
To solve the above technical issues, the present disclosure provides a positionable hidden hydraulic hinge, which includes a non-movable device body configured to be connectable with a door frame, a rotatable device body configured to be connectable with a door leaf, and a hinge configured to connect the non-movable device body and the rotatable device body. The positionable hidden hydraulic hinge also includes a linkage assembly. A positioning mechanism and a hydraulic pressure-resisting mechanism are disposed inside the rotatable device body. The linkage assembly is configured to penetrate throughout the hinge to respectively pivotably connect, at two ends, with the non-movable device body and an inner mechanism of the rotatable device body.
In some embodiments, the non-movable device body and the rotatable device body are configured to be respectively buried (or concealed) in the door frame and the door leaf.
In some embodiments, a positionable hidden hydraulic hinge of the present disclosure includes a hinge, a non-movable device body configured to be connectable with the hinge, and a rotatable device body and a linkage assembly configured to be connectable with the hinge. The non-movable device body and the rotatable device body are configured to be respectively buried in a side edge frame of the room door and a corresponding door frame of the room door. The rotatable device body is provided with a positioning mechanism and a hydraulic pressure-resisting mechanism. The linkage assembly is configured to be connectable with the non-movable device body and the rotatable device body.
In some embodiments, the non-movable device body includes a curved rod fixing base, the curved rod fixing base is configured to be fixedly connectable with the hinge.
In some embodiments, the rotatable device body includes a bearing guiding base, and a hydraulic chamber body. The bearing guiding base is configured to be fixedly connectable with the hinge. The hydraulic chamber body is configured to be fixedly connectable with the bearing guiding base. An interior of the hydraulic chamber body is provided with an end cover of the chamber body, a sealing sleeve of a piston rod, a piston, and a spring.
In some embodiments, the linkage assembly includes a curved rod, a connecting rod, and a bearing. The curved rod is configured to be connectable with the curved rod fixing base through a pin. The connecting rod is configured to be connectable with the curved rod through a pin. Two connecting ends of the connecting rod and the curved rod are respectively provided with a bearing.
The advantages of the present disclosure include: a positionable hidden hydraulic hinge includes a non-movable device body configured to be connectable with a door frame, a rotatable device body configured to be connectable with a door leaf, and a hinge configured to be connectable with the non-movable device body and the rotatable device body. The positionable hidden hydraulic hinge also includes a linkage assembly. A positioning mechanism and a hydraulic pressure-resisting mechanism are disposed inside the rotatable device body. The linkage assembly is configured to penetrate throughout the hinge to respectively pivotably connect, at two ends, with the non-movable device body and an inner mechanism of the rotatable device body. The disclosed structure is simple and compact, convenient for hidden installation, and safe to use.
Next, the present disclosure will be explained in detail through specific embodiments in combination with the accompanying drawings.

In a positionable hidden hydraulic hinge of the present disclosure, when implemented, as shown in
The disclosed structure can achieve a hydraulic, internally disposed, hidden hinge that is positionable, which can automatically close the door, and which has a hydraulic buffer. Compared to existing technologies, because the presently disclosed device can be installed in a concealed or hidden manner, the overall effect of the room door installation is significantly enhanced. The structure is simple, reasonable, and the device performance is stable, the lifetime is long, and the cost is low. The device of the present disclosure is positionable, can automatically close the door, has a hydraulic buffer for anti-wind and anti-hand jamming, has a stable performance, long lifetime, and is useful and durable.
The above content is a further detailed description of the present disclosure with reference to specific embodiments. This cannot be interpreted as indicating that the specific embodiments of the present disclosure are only limited to these descriptions. A person having ordinary skills in the art can perform simple derivation or substitution without departing from the principle of the present disclosure, which should be regarded as being within the scope of protection of the present disclosure.
