Abstract

The utility model relates to a self-positioning type hinge, which is characterized in that a rotary blade which is provided with a screw hole and a fixed blade are mutually hinged through a hinge shaft to form the utility model. At least an irregular polygonal positioning cam is arranged on the periphery of the hinge shaft, and a positioning top block, the amount of which is corresponding to the positioning cam is arranged between the fixed blade and the positioning cam; a positioning spring is arranged in the positioning top block, one end of the positioning spring is fixed with the positioning top block, and the other end of the positioning spring is fixed with the fixed blade; the positioning cam is matched with the positioning top block to cause the rotary blade to be positioned. The utility model has the advantages that the design structure is simple, doors, windows, etc. can be opened and closed limberly, and the doors and the windows which are opened can be correspondingly positioned on needed positions to avoid noise caused by impact of the doors and the windows and to avoid loss caused by fragmentation of glass; the utility model also has certain vicarious function for door closers and ground springs; simultaneously, the utility model has a door holder function and a door attraction function. The utility model is suitable for various doors, windows, tool boxes and furniture.

Description

Self-align hinge

Technical field

The utility model belongs to life haberdashery and hardware articles for use, particularly relates to a kind of door and window can being opened and relative positioning and self-align hinge simple in structure.

Background technology

The hinge that the hinge that present known door and window uses constitutes by two common hinges, rotate by central axis, be generally used for above door and window and the furniture etc., because common hinge rotates flexibly, in use also exist certain defective, as be installed on the door and window, when blowing, owing to be subjected to the influence of wind-force, door and window is got rapidly by wind and opens or closes, not only fierce impact sound can take place, and can make glass of door and window broken because of bump, cause damage; When common hinge was installed on case and bag or the tool box, because it rotates flexibly, case lid can't be fixed, and after opening case lid, it often opens or self-return automatically to be subjected to the external force effect, must take article on the other hand with a hand steered case lid, and is very inconvenient.Although occur some Locational hinges in the near future, because of its complex structure, cause difficulty of processing big, the cost height.

Summary of the invention

The utility model provides a kind of simple in structure, easy to use for solving the technical problem that exists in the known technology, can be on desired location with the door and window relative positioning opened, and the low self-align hinge of cost.

The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:

Self-align hinge, mainly be to be hinged by the hinge axle by moving blade that has screw hole and fixed blade to constitute, at least be provided with a positioning cam in hinge axle periphery, at the location jacking block that fixedly is provided with between hinge and positioning cam with its respective numbers, be fixed with retainer spring in the jacking block of location, positioning cam matches with the location jacking block to make and rotates the hinge location.

The utility model can also adopt following technical measures to realize:

Described positioning cam is irregular polygonal.

Described retainer spring one end is fixed with the location jacking block, and the other end and fixed blade are fixed.

Advantage and the good effect that the utlity model has are: project organization is simple, not only make switches such as door and window, case lid flexible, and can be on the desired position with the door and window opened or case lid relative positioning, noise and the broken loss that causes of glass have been avoided because of the generation of door and window bump, door closer and ground spring there are certain substitution effect, are fit to be applied on door and window, furniture or the tool box.

Description of drawings

Fig. 1 is an overall structure schematic diagram of the present utility model;

Fig. 2 is that the A---A of Fig. 1 is to sectional view;

Fig. 3 is that the utility model is in the state diagram of opening 100 ° of angles;

Fig. 4 is that the utility model is in the state diagram of opening 60 ° of angles;

Fig. 5 is that to be in closure be 0 ° state diagram to the utility model.

The specific embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

See also Fig. 1-Fig. 5, self-align hinge comprises moving blade 1 and the fixed blade 2 that has screw hole, by hinge axle 4 formation that is hinged, on the hinge axle, be provided with hinge axle sleeve 3, hinge axle periphery is provided with a positioning cam 5 at least, this cam is irregular polygonal, 5 location jacking blocks 6 that are provided with its respective numbers between fixed blade 2 and positioning cam, in the jacking block of location retainer spring 7 is housed, positioning cam matches with the location jacking block and makes the moving blade location, retainer spring one end is fixed with the location jacking block, and the other end and fixed blade are fixed.It is 0 degree, 60 degree, 100 degree and 180 degree that positioning cam is provided with four rest points, rest point is 0 when spending, hinge is tight closed condition, and certain closing force is arranged, and the location jacking block to the reinforcing of the center of positioning cam, makes its rotation under the retainer spring active force, positioning cam rotates to angle when being 60 ° under external force, can orientate half opening-wide state as, when rotating to 100 °, for opening-wide state and the effect of fixed door is arranged.When positioning cam rotates an angle when cutting the peak that does not reach rest point under external force, self-align hinge can set back automatically, if surpass the peak of this setting, it can slide to second rest point automatically.

Claims

1. self-align hinge, mainly be by hinge axle (4) formation that is hinged by the moving blade that has screw hole (1) and fixed blade (2), it is characterized in that: be provided with a positioning cam (5) at least in hinge axle periphery, at the location jacking block (6) that fixedly is provided with between hinge and positioning cam with its respective numbers, be fixed with retainer spring (7) in the jacking block of location, positioning cam matches with the location jacking block to make and rotates the hinge location.

2. according to claim 1. self-align hinge is characterized in that: described positioning cam is irregular polygonal.
