Described shifting block is provided with and can and makes two articulated bodies keep the open second roof pressure portion with the pivot interaction.
Be provided with transition part between the described first roof pressure portion and the second roof pressure portion, and this first roof pressure portion and the second roof pressure portion are by the transition part smooth transition.
Described flexible member is a torsion spring.
Described articulated body is provided with bearing pin, and described shifting block articulates by bearing pin and articulated body.
Described shifting block is provided with groove, and described torsion spring is installed in this groove.
Described torsion spring is connected with bearing pin.
Be equipped with axle sleeve on the described pivot, the described first roof pressure portion and the second roof pressure portion push mutually with axle sleeve.
The beneficial effects of the utility model are: the utility model is provided with the shifting block with its pivot joint in articulated body, be provided with torsion spring between shifting block and articulated body, elastic force by torsion spring can make the first roof pressure portion push mutually with pivot, two articulated bodies that drive with its flexible connection by the pivot that is extruded close up, thereby closing automatically of door that realization and articulated body are fixing or window, help the user to form the good custom of " turnover is closed the door ", " shutting the door after you ", avoid the artificial phenomenon of not exclusively closing at closing time, thereby can save the chamber with cold air or heating installation resource; This utility model can make the second roof pressure portion push mutually with pivot by the elastic force of torsion spring, open with two articulated bodies of its flexible connection by the pivot drive that is extruded, thereby door or window can be in open mode always, conveniently meet guests, transport goods, work such as ventilation.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Overview when Fig. 1 is the utility model closure state;
Overview when Fig. 2 is the utility model open mode;
Fig. 3 is an explosive view of the present utility model;
Fig. 4 is the overview of shifting block.
The specific embodiment
Referring to figs. 1 through Fig. 4, the utility model discloses a kind of self cut-off type concealed hinge, comprise the articulated body 1 of at least two hinged cranking arm 2, flexibly connecting with 2 pivots that are rotationally connected 3 of cranking arm, with pivot 3, be provided with shifting block 4 in the articulated body 1 with its pivot joint, 1 of shifting block 4 and articulated body are provided with flexible member 5, these flexible member 5 one ends withstand on the articulated body 1, and the other end withstands on the shifting block 4, and this shifting block 4 is provided with and can interacts with pivot 3 and make pivot 3 drive the first roof pressure portion 41 that articulated bodies 1 close up.Further, described shifting block 4 is provided with and can and makes two articulated bodies 1 keep the open second roof pressure portion 42 with pivot 3 interactions.
As shown in the figure, in this example, the first roof pressure portion 41 and 42 in the second roof pressure portion are provided with transition part 43, and this first roof pressure portion 41 and the second roof pressure portion 42 are by transition part 43 smooth transition, the said structure design makes pivot 3 and shifting block 4 can reduce wearing and tearing in the process of extruding, further, be equipped with axle sleeve 6 on the pivot 3, the described first roof pressure portion 41 and the second roof pressure portion 42 push mutually with axle sleeve 6, axle sleeve 6 can rotate mutually with pivot 3, make pivot 3 and the sliding friction of shifting block 4 in the process of extruding change rolling friction into, reduced frictional dissipation greatly, improved the application life of parts.
As shown in the figure, in this example, flexible member 5 is a torsion spring, and is in pressured state all the time, and torsion spring is a kind of general flexible member 5, and not only structure is little, and it is little to take up room, and low price.Articulated body 1 is provided with bearing pin 55, and shifting block 4 articulates by bearing pin 55 and articulated body 1, and shifting block 4 is provided with groove 44, and torsion spring is installed in this groove 44, and torsion spring is connected with bearing pin 55.Said structure is the decision design of this example, by the not only easily processing of above-mentioned part, easily assembling, and compact conformation, saving space.
The course of work of the present utility model is as follows: when door or window are closed; two articulated bodies 1 are in closure state; torsion spring is in pressured state; pivot 3 pushes mutually with an end of the first roof pressure portion 41; when door or window are opened; two articulated bodies 1 are opened thereupon; drive pivot 3 and crank arm and 2 slide along certain track articulated body 1 in, pivot 3 pushes the first roof pressure portion 41 when slip, if remove external force at this moment; pivot 3 pushes in the first roof pressure portion 41 under the effect of spring force so; produce a component opposite on pivot 3, make pivot 3 anti-phase motion with pivot 3 directions of motion, thus drive crank arm 2 and articulated body 1 close up; drive door or window and close, thereby realize closing automatically of door or window.But when people open door or window sometimes, do not wish the door or window shut automatically, under the above-mentioned situation of opening door and window, continue to push away or sliding door and window, the folding angle of door and window is strengthened, at this moment, pivot 3 has slided into the second roof pressure portion 42 from the first roof pressure portion 41 by transition part 43, pivot 3 pushes in the second roof pressure portion 42 under the effect of spring force, produce a component identical on pivot 3 with pivot 3 directions of motion, make pivot 3 continue to move, push up on the wall or reach the maximum stretching degree of two articulated bodies 1 up to door or window, under this state, door or window keep this opening always under the effect of elastic force.
Above-mentionedly just preferred embodiments more of the present utility model are illustrated and describe; but embodiment of the present utility model is not restricted to the described embodiments; as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model.
