Abstract

The utility model relates to a hinge installed on doors, windows, furniture and bags, particularly a positioning hinge. The positioning hinge comprises two metal blades with screw holes; the two metal blades are hinged together through hinges. Position-limiting structures are uniformly distributed and arranged on the surface of a shaft sleeve of a rotating blade; a locking mechanism is arranged on a plane of a fixed blade which is matched with the shaft sleeve of the rotating blade; the locking mechanism is matched with the position-limiting structures to make the rotating blade positioned. The positioning hinge not only makes doors, windows and box covers opened or closed neatly, but also has definite damping action when opened and makes opened doors, window sashes or box covers positioned at required positions. The noise generated when used can be eliminated.

Description

Locational hinge

The utility model relates to and is used for the hinge installed on door, window, furniture, the case and bag, particularly a kind of Locational hinge.

The hinge that widely used common hinge is made of two metal blades rotates by central axis.Be generally used for above door, window, furniture, the case and bag etc., because common hinge rotates flexibly, in use also exist certain defective, be installed on the door and window as common hinge, open the door, when windowing if be subjected to the influence of wind-force, door can take place every now and then frequently clash into doorframe, window and window frame, people's rest is interfered.When blowing, door and window is got rapidly by wind and opens or closes, and not only fierce impact sound can take place, and can make door, window glass because of the bump fragmentation, causes damage.When common hinge is installed on tool box, the electricity meter box, because common hinge rotates flexibly, case lid can't arbitrarily be located, and during use, after opening case lid, it often opens or self-return automatically to be subjected to the external force effect.Common hinge is installed on the case and bag, and when opening case and bag, a necessary hand steered case lid is taken article on the other hand, and is very inconvenient.

The purpose of this utility model is to provide a kind of Locational hinge, be installed in the Locational hinge on door, window, the case and bag, not only make door, window, case lid switch flexible, and can certain damping action and can be with door, sash or the case lid relative positioning opened on the desired position be arranged opening door, sash and case lid.Can eliminate the noise that produces when using, easy to use.

The utility model is achieved in that a kind of Locational hinge, comprise two metal blades that have screw hole, be hinged together by hinge, the uniform position limiting structure that is provided with on the axle sleeve surface of moving blade, the fixed blade plane of matching with the moving blade axle sleeve is provided with locking mechanism, and locking mechanism matches with position limiting structure and makes the moving blade location.

Because the uniform position limiting structure that is provided with on the axle sleeve surface of the moving blade of Locational hinge, fixed blade is provided with the locking mechanism that matches with moving blade axle sleeve upper limit structure, moving blade can be locked on the desired position easily.Moving vane is installed on door leaf, sash or the case lid during installation, and fixed blade is installed on doorframe, window frame or the casing, not only opens flexibly, and by the lock function on the moving blade, door leaf, sash or case lid is locked on the desired position easily.Because locking mechanism is the elastic compression frictional fit with cooperating of position limiting structure, Locational hinge is in damping state all the time and locatees at any time when switch rotates, thereby in the influence of opening the door, be subjected to when windowing wind-force, also impingement phenomenon can not occur.When Locational hinge is installed on the casing, open case lid, Locational hinge can make case lid be positioned on the desired position, can hold up case lid without hand, uses very convenient.

Fig. 1 looks the agent structure schematic diagram for the master of the utility model embodiment 1, and Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1, and the master of Fig. 3 the utility model embodiment 2 looks the agent structure schematic diagram, and Fig. 4 is the B-B sectional structure schematic diagram of Fig. 3.

Below in conjunction with accompanying drawing the utility model is further described

A kind of Locational hinge, comprise two metal blades that have screw hole, be hinged together by hinge, the uniform position limiting structure that is provided with on axle sleeve 2 surfaces of moving blade 1, fixed blade 3 planes of matching with the axle sleeve 2 of moving blade 1 are provided with locking mechanism, and locking mechanism matches with position limiting structure and makes the moving blade location.Embodiment 1 as shown in Figure 1 and Figure 2, position limiting structure is the prismatic surface 4 in the surperficial uniform setting of the axle sleeve 2 of moving blade 1, the elastic spring 5 of locking mechanism on fixed blade 3 planes, fixedly installing, the free end of elastic spring 5 is a curved surface, and the prismatic surface 4 on the axle sleeve 2 of the curved surface of elastic spring 5 and moving blade 1 matches.Rely on the squeezing action power of the prismatic surface 4 of 5 pairs of axle sleeves 2 of elastic spring, make that the opening and closing degree of two blade faces is relatively stable, constitute the locating effect of hinge, the size of its opening and closing detent force is influenced by the width of the prismatic surface 4 of the elastic force of elastic spring 5 and axle sleeve 2.In application, locate dynamics with the different respective design of product variety.Embodiment 2 as shown in Figure 3, Figure 4, position limiting structure is being provided with locating hole 6 for radial equipartition on axle sleeve 2 surfaces of moving blade 1, fixed blade 3 planes are provided with spring latch lock 7, and spring latch lock 7 is gone up uniform locating hole 6 with axle sleeve 2 surfaces of moving blade 1 and matched.It is relatively stable to make that two blade faces are opened the degree of closing, and constitutes the locating effect of hinge.
