Description

Technical Field

[0001] The utility model relates to the technical field of metal connectors, in particular to a movable hinge. Background Art

[0002] A movable hinge is a mechanical device used to connect two solids and allow relative rotation between them. It usually consists of movable components or foldable materials. The design of the movable hinge allows an object to rotate freely in two or more directions, thus achieving flexible movement of the object. Such hinges are very common in daily life and industrial applications, such as the opening and closing of doors and windows, the assembly and disassembly of furniture, etc.

[0003] Now, the structure of some hinge products is a hydraulic structure; the principle is to utilize hydraulic buffer technology to provide an ideal buffer effect through high-density oil flowing directionally in a sealed container; the function is resistance and buffering; the technological process of manufacturing this product is stamping and injection molding of hardware parts to achieve the effects of silence and resistance functions. However, the resistance effect of some hinges is not ideal. When the door of the existing hinge product is closed, there is a resistance effect, and when the door is closed, the angle of the resistance point is too small to achieve the resistance effect of an effective 95-degree round-trip stroke. Moreover, due to the structural problems of the existing product itself, it can only achieve resistance in a single direction, cannot achieve bidirectional resistance, and cannot achieve buffering and resistance pausing effects at any angle. The resistance effect needs to be improved. Summary of the Utility Model

Specific implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Referring to Figures 1-5 , the movable hinge includes a main body contact locking plate 1. A page contact locking plate 7 is provided on one side of the main body contact locking plate 1. A page position angle braking bottom rod 4 is rotatably provided on the page contact locking plate 7. A damper mechanism 8 is rotatably provided on the page contact locking plate 7 on one side of the page position angle braking bottom rod 4. The damper mechanism 8 includes a resistance rod 82. One end of the resistance rod 82 is rotatably provided on the page position angle braking bottom rod 4. An installation shell 81 is provided at the other end of the resistance rod 82 away from the page position angle braking bottom rod 4. A cavity is opened in the installation shell 81. The resistance rod 82 is inserted into the cavity of the installation shell 81. A damping block 83 is provided inside the installation shell 81. The damping block 83 contacts the resistance rod 82. The damping block 83 is used to play an effective damping role.

[0023] Moreover, an installation groove 811 is provided in the installation shell 81. The damping block 83 is installed at the installation groove 811. The upper surface of the damping block 83 contacts the resistance rod 82. A rubber block 821 is provided in the middle of the bottom surface of the resistance rod 82. The rubber block 821 contacts the damping block 83. The contact between the rubber block 821 and the damping block 83 generates damping.

[0024] At the same time, one side of the installation shell 81 is rotatably connected to a main position angle braking bottom rod 3. The middle of the main position angle braking bottom rod 3 is rotatably connected to the page position angle braking bottom rod 4. The other end of the main position angle braking bottom rod 3 away from the installation shell 81 is rotatably connected to the main body contact locking plate 1. The page position angle braking bottom rod 4 is used to play a connecting role.

[0025] Moreover, a main position angle braking upper rod 2 is rotatably arranged on the other side of the main position angle braking bottom rod 3 on the main body contact locking plate 1. At the other end of the angle braking upper rod 2 away from the main body contact locking plate 1, an angle braking pressure spring 5 is connected and arranged. At the other end of the angle braking pressure spring 5 away from the angle braking upper rod 2, it is connected and arranged on the main position angle braking bottom rod 3. The angle braking pressure spring 5 is used for resetting.

[0026] In addition, a page position angle braking upper rod 6 is externally covered on the damper mechanism 8. The middle of the page position angle braking upper rod 6 is rotatably installed on the main position angle braking bottom rod 3. One end of the page position angle braking upper rod 6 is rotatably installed at the end of the main position angle braking upper rod 2 away from the main body contact locking plate 1.

The movable hinge as a whole is made of stainless steel, making its corrosion resistance better, and while having high strength, its weight is also relatively low.

The resistance rod 82 moves within the installation shell 81, and the damping block 83 contacts the rubber block 821, thereby playing a role in buffering resistance.

[0029] And for the main body contact locking plate 1, the main position angle braking upper rod 2, the main position angle braking bottom rod 3, the page position angle braking bottom rod 4, the angle braking pressure spring 5, the page position angle braking upper rod 6, the page contact locking plate 7, and the damper mechanism 8 in this article, the pin 9 is used to achieve the rotational connection.

And it adopts a physical activity extrusion structure, does not require the use of hydraulic oil, does not have an oil leakage phenomenon, can achieve a fireproof and flame-retardant effect, can be installed on a fire door, and is not affected by seasons and temperature.
