Abstract

The utility model relates to a fire door butt hinge. The fire door butt hinge is mainly formed by that a plurality of elliptical holes are opened on a first butt hinge sheet, and a first teeth-bar-shaped saw tooth is formed under the position of the intermediate section of the first butt hinge sheet; a second butt hinge sheet is arranged corresponding to the position under the first butt hinge sheet, a plurality of bolt holes are opened on the second butt hinge sheet corresponding to the positions of the elliptical holes, and a second teeth-bar-shaped saw tooth is form on the intermediate section of the second butt hinge sheet; by that the saw teeth between the two butt hinge sheets are mutually engaged, and by that screw nails are penetrated in the elliptical holes and the bolt holes, the two butt hinge sheets are combined, to prevent the slide of the butt hinge sheets caused by the vibration of a fire door when the fire door is opened or closed, so the fire door can be opened and closed conveniently; simultaneously, the utility model can also make the relative positions of the two butt hinge sheets adjusted, so the space between the fire door and a door frame is adjusted.

Description

Fire door butt hinge

The utility model relates to a kind of labeled door hinge, mainly is to be formed with sawtooth in the hinge plate below, and is meshing with each other with another saw-toothed hinge plate in top, causes sliding phenomenon because of labeled door to prevent hinge plate when opening and closing, and makes labeled door can be convenient to open and close.

The existing labeled door hinge of generally commonly using (as shown in Figure 4), mainly be to be used in hinge plate (A) to be provided with some through holes (B), this hinge plate (A) is located at labeled door (C) top position, be provided with corresponding screw (D) corresponding to hinge plate (A) through hole (B) position simultaneously, and utilize screw (E) that hinge plate (A) is installed in labeled door (C) top, make labeled door (C) able to turn on or off by being located at labeled door (C) top hinge plate (A) drive labeled door (C).But this labeled door hinge has easily because of through hole (B) and screw (D) and is difficult for aligning and can't proofreaies and correct under the situation of its relative distance, may cause labeled door (C) to open and close and have some setbacks because of the distance between labeled door (C) and hinge plate (A) and when incorrect.In addition, engage (as shown in Figure 5) of the iron doorframe of generally commonly using and iron gate, promptly when the point of the G among the figure and F point during at a distance of 5mm, and H point and I point are when colliding together, the unlatching of labeled door just has some setbacks, and have to adjust the distance that F point and G order is 3mm, but this moment F point with the G point between apart when differing from half screw hole, can't crack a joke at D point side place and tighten up a screw (as shown in Figure 4), then need labeled door (C) is renewed again.Therefore, commonly use the good design of labeled door hinge real non-,, and the necessity that is improved is arranged so its practicality is not good.

Main purpose of the present utility model is to provide a kind of labeled door hinge in order to overcome above-mentioned the deficiencies in the prior art part, this labeled door hinge is that the hinge plate below is designed to zigzag, and be meshing with each other with another saw-toothed hinge plate in top, preventing that hinge plate from causing slip because of labeled door when opening and closing, and make labeled door be convenient to open and close.

Another purpose of the present utility model provides the relative position that can adjust between hinge plate, also is convenient to adjust simultaneously the distance between labeled door and doorframe.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is the three-dimensional exploded view of labeled door hinge of the present utility model;

Fig. 2 is the enforcement illustration of labeled door hinge of the present utility model;

Fig. 3 be labeled door hinge of the present utility model in conjunction with sectional view;

Fig. 4 is an outward appearance exploded view of commonly using hinge;

Fig. 5 is an embodiment vertical view of commonly using structure;

The utility model is a kind of labeled door hinge (1) (as shown in Figure 1), from then on can find out the overall structure of this creation among the figure, this design mainly is to be provided with several elliptical apertures (20) in hinge plate (2), and hinge plate (2) middle section position below is formed with spline-simulating sawtooth (21), be provided with another hinge plate that can be fixed in the labeled door end face (3) corresponding to hinge plate (2) below, this hinge plate (3) locates to be formed with some screws (30) side by side corresponding to elliptical aperture (20), and place, top, hinge plate (3) stage casing also is formed with spline-simulating sawtooth (31), and utilize the sawtooth (21) (31) between two hinge sheet (2) (3) to be meshing with each other, utilize screw (4) to be arranged in elliptical aperture (20) and the screw (30) simultaneously, so that two hinge sheet (2) (3) is fixed, preventing that hinge plate from causing slip because of labeled door when opening and closing, and make labeled door be convenient to the location.

As shown in Figure 2, be the enforcement illustration of the utility model labeled door hinge.Utilize screw (4) to pass elliptical aperture (20) the two hinge sheet (2) (3) of labeled door hinge of the present utility model and in the sealed screw (30) to another hinge plate (3), and make hinge plate (2) (3) be fixed to labeled door (5) top one side position, the location because the sawtooth (21) (31) of hinge plate (2) (3) is meshing with each other, thereby can prevent suitably that labeled door (5) from causing the bad phenomenon of slip when opening and closing vibrations, and provide the labeled door advantage that (5) are easy to locate.

As shown in Figure 3, for the utility model labeled door hinge in conjunction with sectional view, when if the collocation of the spacing between labeled door (5) and doorframe is also incorrect, may cause labeled door (5) to produce and open and close bad phenomenon, therefore can utilize the elliptical aperture (20) on the hinge plate of the present utility model (2) to make transverse moving left and right, and the spacing between change hinge plate (2) and hinge plate (3), can adjust simultaneously the spacing size between labeled door (5) and doorframe, open and close advantage smoothly thereby labeled door (5) is had.

Comprehensive the above, compare and more can reach the enhancement effect with commonly using structure on the overall structure of the present utility model, make it more increase practical effect.To those skilled in the art, may do a lot of change and modification to specific embodiment according to the above description, but still not break away from protection domain of the present utility model, so claim of the present utility model is limited by claims.

Claims

1, a kind of labeled door hinge mainly is to be provided with several elliptical apertures in hinge plate, is provided with another hinge plate corresponding to the hinge plate below, and the corresponding elliptical aperture of this hinge plate is formed with some screws side by side, it is characterized in that:

Two hinge plate middle section positions are formed with the spline-simulating sawtooth, and it is fixing to utilize sawtooth between two hinge plates to be meshing with each other, and wears in elliptical aperture and the screw with screw, and two hinge plates are tightened up.
