Description

Multi-angle open concealed hinge

technical field

The utility model relates to the technical field of hidden hinges, in particular to a multi-angle opening hidden hinge.

Background technique

With the improvement of people's living standards and the acceleration of the pace of life, people's awareness of prevention is also increasing. Therefore, there are various anti-theft doors and steel doors sold on the market, each of which has a different design concept, and strives to meet the anti-theft requirements of different users.

Anti-theft doors and steel doors on the market generally adopt C-shaped stamping adjustable concealed chains, and the opening angle of the door leaf is narrow, generally around 90 degrees. It will bring a lot of inconvenience to users when installing and using it in public places or narrow corridors . Because anti-theft doors and steel doors are usually installed on the outer wall and opened outwards, the existing hidden chains cannot be opened to more than 90 degrees, and do not have the function of positioning and opening. After opening, they are easy to rotate, which hinders the user's life and Work.

Utility model content

In view of the above disadvantages, the purpose of this utility model is to provide a multi-angle open concealed hinge with ingenious and reasonable structural design, convenient use, large opening angle, and positionable opening.

In order to achieve the above object, the technical solution provided by the utility model is:

A multi-angle open concealed hinge, which includes an angular profile, a first hinge body and a second hinge body, the middle section of the angular profile is bent at a right angle to form a right-angle part, and the upper part of the vertical wall of the right-angle part is concave inward Insert to form a card position, and a positioning protrusion matching the card position is provided on the plate body, a small arc-shaped part and a large arc-shaped part inclined upward are sequentially provided on the horizontal wall of the angular profile, and the first hinge The whole of the body is C-shaped, and the whole of the second hinge body is L-shaped. One end of the first hinge body is arranged on the inside of the right-angle part of the angular profile through the re-pin shaft, and the other end protrudes from the angular profile and the second hinge. One end of the second hinge body is fixed, and the other end of the second hinge body is arranged on the plate body through the rotating pin shaft. The connection between the small arc portion and the large arc portion forms a positioning recess. When the plate body is opened to 110 degrees, the positioning protrusion of the plate body is just stuck on the positioning recess, realizing the purpose of positioning and opening 110 degrees. When the plate body continues to open, the positioning protrusion of the plate body slides out of the positioning concave position and opens to 160 degrees. Under the limit of the protrusion of the small arc part, the purpose of positioning and opening 160 degrees is realized. Except for the large arc part It can form a positioning concave position with the small arc-shaped part, and also play a role of deformation buffer, effectively avoiding the damage of the board due to vigorous opening, and prolonging the service life.

The beneficial effects of the utility model are: the utility model has ingenious and reasonable structural design, small volume, and can be concealed inside the angular profile when closed, ensuring that the hinges are not exposed when the door leaf is closed, and greatly improving the overall firmness of the door leaf. The crowbar cannot directly damage the hinge, which greatly improves the safety performance; when opening and closing, the positioning concave position on the angular profile and the positioning protrusion of the plate body can be positioned to open at 110 degrees or 160 degrees, not only The opening angle is wide and has a positioning effect, which brings convenience to people's use. In addition, the utility model has a compact and simple overall structure, is easy to realize, and has low cost, which is conducive to wide popularization and application.

Below in conjunction with accompanying drawing and embodiment, the utility model is further described.

Detailed ways

Embodiment, referring to Fig. 1, Fig. 2 and Fig. 3, this embodiment provides a multi-angle open concealed hinge, which includes an angular profile 1, a first hinge body 2 and a second hinge body 3, the angular profile The middle section of 1 is bent at a right angle to form a right-angle part 11, and the upper part of the vertical wall of the right-angle part 11 is inwardly recessed to form a card position 12, and a positioning protrusion matching the card position 12 is provided on the board body 4 41, one side of the positioning protrusion 41 is provided with a mounting seat 42 on the plate body 4, and the horizontal wall of the angular profile 1 is sequentially provided with a small arc-shaped part 13 and a large arc-shaped part 14 inclined upward. One end of a hinge body 2 is arranged on the inner side of the right angle part 11 of the angular profile 1 through a revolving pin shaft. The whole of the first hinge body 2 is C-shaped, and the other end of the hinge body 2 protrudes from the angular profile 1 through screws and the second. One end of the hinge body 3 is fixed, and the whole of the second hinge body 3 is L-shaped, and the other end thereof is connected with the mounting seat 42 on the plate body 4 through a revolving pin shaft.

Preferably, the lower part of the vertical wall protrudes outward to form a limiting protrusion 16, the lower side of the limiting protrusion 16 is bent inward, and then extends horizontally for a certain distance to form a bottom edge fixing part 17, which is convenient The installation is fixed and the stability is good. The free end of the large arc portion 14 extends horizontally for a certain distance, and then bends downward to form a side fixing portion 18 . Easy to install, good structural stability and high safety. An end of the side fixing portion 18 is bent upward toward one side of the right-angle portion 11 to form an upper rib 19 . An end of the bottom edge fixing portion 17 is bent upward to form the lower retaining edge 10 . An upper rib 19 and a lower rib 10 are provided, which not only have a better positioning effect, but also are not easy to scratch the hands during installation, which brings convenience to installation and use.

When the plate body 4 (equivalent to the door leaf) is closed, the multi-angle opening hidden hinge of the utility model can conceal the angular profile 1 to ensure that the hinge is not exposed when the door leaf is closed, which greatly improves the overall firmness of the door leaf. The stick cannot directly damage the hinge, which greatly improves the safety performance.

When the angle a of the plate body 4 is opened to 110 degrees, the positioning protrusion 41 of the plate body 4 is just stuck on the positioning recess 15, and the purpose of positioning and opening 110 degrees is realized. When the plate body 4 continues to open, the positioning protrusion 41 of the plate body 4 slides out of the positioning recess 15, and when the plate body 4 opens at an angle b to 160 degrees, it is forced by the protrusion limit of the small arc portion 13 to realize positioning Turn on the purpose of 160 degrees. It has different opening angles, which brings convenience to people.
