Description
Technical field
The utility model relates to the technical field of blind hinge, is specifically related to a kind of multi-angle and opens blind hinge.
Background technology
Along with the raising day by day of people's living standard and the quickening of rhythm of life, the prevention awareness of people is also strengthened day by day.So the security door sold on the market, steel door are varied, it has different design concepts separately, makes every effort to the antitheft requirement that can reach different user.
Security door on market, steel door etc. generally adopt C type punching press adjustable dark hinge, and opened door leaf angle is narrower, generally at about 90 degree, in public places or narrow corridor is installed and used its and understand and bring inconvenience to user.Because security door, steel door, be usually arranged on wall face and outwards open, existing dark hinge can not be opened to being greater than 90 degree, and does not have the function of opening location, after opening, easily rotates, hampers life and the work of user.
Utility model content
For above-mentioned deficiency, the purpose of this utility model is, provide a kind of smart structural design, rationally, easy to use, opening angle is large, and the multi-angle can locating unlatching opens blind hinge.
For achieving the above object, technical scheme provided by the utility model is:
A kind of multi-angle opens blind hinge, it comprises horn shape section bar, first hinge bodies and the second hinge bodies, the middle section position of described horn shape section bar is at right angles bent to form right angle portion, the vertical wall top in this right angle portion inwardly concaves formation screens, and on plate body, be provided with the positioning convex suitable with this screens, the horizontal wall of this horn shape section bar is provided with successively the little curved portions and large curved portions that tilt upward, the entirety of the first hinge bodies is C font, the entirety of the second hinge bodies is L-shaped, one end of first hinge bodies is arranged on inside the right angle portion of described horn shape section bar by axle of shipping and reselling on another market, one end that the other end stretches out horn shape section bar and the second hinge bodies fixes, the other end of this second hinge bodies is arranged on plate body by axle of shipping and reselling on another market.Junction between little curved portions and large curved portions is formed locates recess, and when plate body is opened into 110 degree, the positioning convex of plate body is just in time stuck on the recess of location, realizes the object of location unlatching 110 degree.When plate body continues to open, the positioning convex of plate body skids off location recess, be opened into 160 degree, under spacing under the pressure of the projection of little curved portions, realize the object of location unlatching 160 degree, large curved portions, except forming the effect of locating recess with little curved portions, also plays deformation cushioning effect, effectively avoiding causing plate body to occur breaking phenomenon because opening energetically, increasing the service life.
The beneficial effects of the utility model are: the utility model smart structural design, rationally, volume is little, in horn shape section bar that can be hidden during closedown, when ensureing that door leaf cuts out, hinge does not expose, improve the integral firmness of door leaf dramatically, crowbar cannot directly destroy hinge, greatly improves security performance; During opening and closing, matched with the positioning convex of plate body by the location recess on horn shape section bar, can locate and be open at 110 degree or 160 degree of places, not only opening angle exists, and has locating effect, uses bring convenience to people, the utility model compact overall structure, simple in addition, be easy to realize, cost is low, is beneficial to wide popularization and application.
Below in conjunction with accompanying drawing and embodiment, the utility model is further illustrated.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is structural representation when opening 110 degree of the present utility model.
Fig. 3 is structural representation when opening 160 degree of the present utility model.
Detailed description of the invention
Embodiment, see Fig. 1, Fig. 2 and Fig. 3, a kind of multi-angle that the present embodiment provides opens blind hinge, it comprises horn shape section bar 1, first hinge bodies 2 and the second hinge bodies 3, the middle section position of described horn shape section bar 1 is at right angles bent to form right angle portion 11, the vertical wall top in this right angle portion 11 inwardly concaves and forms screens 12, and on plate body 4, be provided with the positioning convex 41 suitable with this screens 12, one side position of corresponding positioning convex 41 is provided with mount pad 42 in plate body 4, the horizontal wall of this horn shape section bar 1 is provided with successively the little curved portions 13 and large curved portions 14 that tilt upward, one end of first hinge bodies 2 is arranged on inside the right angle portion 11 of described horn shape section bar 1 by axle of shipping and reselling on another market, the entirety of the first hinge bodies 2 is C font, its the other end is stretched out horn shape section bar 1 and is fixed by one end of screw and the second hinge bodies 3, the entirety of this second hinge bodies 3 is L-shaped, its the other end is connected with the mount pad 42 on plate body 4 by axle of shipping and reselling on another market.
Preferably, form spacing preiection 16 in the bottom outwardly convex of described vertical wall, the lower side of this spacing preiection 16 bends inwards, and then horizontal-extending certain distance forms base fixed part 17, and convenient installation is fixed, good stability.The free end horizontal-extending certain distance of described large curved portions 14, is then bent to form side fixed part 18 downwards.Be convenient to install, structural stability is good, and safety is high.The direction, side in the end of described side fixed part 18 upwards described right angle portion 11 is bent to form rib 19.The end of described base fixed part 17 is upwards bent to form lower stop edge 10.Be provided with rib 19 and lower stop edge 10, not only there is good locating effect, and not easily scratch staff when mounted, bring convenience to installing and using.
When closing plate body 4 (being equivalent to door leaf), the utility model multi-angle is opened in the hidden horn shape section bar 1 of blind hinge energy, when ensureing that door leaf cuts out, hinge does not expose, improve the integral firmness of door leaf dramatically, crowbar cannot directly destroy hinge, greatly improves security performance.
When the angle a to 110 opening plate body 4 spends, the positioning convex 41 of plate body 4 is just in time stuck on the recess 15 of location, realizes the object of location unlatching 110 degree.When plate body 4 continues to open, the positioning convex 41 of plate body 4 skids off location recess 15, when plate body 4 opening angle b to 160 spend, under spacing under the pressure of the projection of little curved portions 13, realizes the object of locating unlatching 160 degree.There is different opening angles, use to people and bring convenience.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change above-mentioned embodiment and revise.Therefore, the utility model is not limited to detailed description of the invention disclosed and described above, also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although employ some specific terms in this manual, these terms just for convenience of description, do not form any restriction to the utility model.As described in the utility model above-described embodiment, adopt structure same or analogous with it and other hinge obtained, all in the utility model protection domain.
