Description
Technical field
The utility model relates to the Domestic hinge of a kind of Domestic hinge, particularly a kind of self-closing.
Background technology
At present, the hinge that furniture is used is generally one-part form, and its structure comprises pivoted arm and hinge cup, and pivoted arm is provided with base, and and the hinge cup between be provided with articulated elements.Articulated elements comprises outer articulated elements and interior articulated elements, and outer articulated elements and interior articulated elements are hinged with following installation shaft with the last installation shaft of pivoted arm respectively, and last installation shaft is provided with spring, and an end of spring withstands on outer articulated elements outer wall, and the other end withstands on the fixed axis of pivoted arm.When closing door leaf,, outer articulated elements can be resetted fast by the effect of spring force., because the reset speed of outer articulated elements is very fast, so the speed that door leaf cuts out is also very fast.Except bigger noise occurs at closing time, influence outside operate as normal, the life, also can occur because of the too fast phenomenon that crushes a hand of door leaf closing velocity, safety and poor reliability, therefore the Domestic hinge of traditional one-part form can not satisfy higher instructions for use.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of structure firm, safe and reliable Domestic hinge.
The purpose of this utility model is achieved in that a kind of Domestic hinge, comprise pivoted arm and hinge cup, pivoted arm is provided with base, and and hinge cup between be provided with outer articulated elements and interior articulated elements, outer articulated elements and interior articulated elements are hinged with the last installation shaft and the following installation shaft of pivoted arm respectively, last installation shaft is provided with spring, one end of spring withstands on outer articulated elements outer wall, the other end withstands on the fixed axis of pivoted arm, it is characterized in that: have cavity on the described base, be provided with buffer in the cavity.
Described buffer comprises sealed at both ends cylinder body, be located at the piston rod in the cylinder body and be fixed on piston on the piston rod, have the external seal groove on the outer surface of piston, external seal groove both sides are provided with seal along having damping hole and return port on the piston axis direction in the external seal groove.
The tail end of described cylinder body and pivoted arm are for being movably hinged.
The exposed junction of described piston rod and interior articulated elements are for being movably hinged.
Have interior seal groove between described piston and the piston rod, interior seal groove is provided with seal.
The two ends of described cylinder body are equipped with y-shaped ring.
Seal is an O-ring seals on the described piston.
The utility model is by improving existing Domestic hinge, is provided with buffer on the base of the pivoted arm of hinge.By the damping effect of band damping hole piston in motion process in the buffer, the closing speed of articulated elements reduces in making, thus the closing speed of the door leaf that slows down, and articulated elements drives the buffer action in driving with spring simultaneously, makes the reliability of buffering stronger.Therefore, the hinge for furniture of this structure can effectively prevent to crush because of the door leaf closing velocity is too fast a hand, high safety.
Description of drawings
Fig. 1 is the structural representation of the utility model most preferred embodiment.
Fig. 2 is a piston structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
According to Figure 1 and Figure 2, Domestic hinge of the present utility model comprises pivoted arm 1 and hinge cup 2, pivoted arm 1 is provided with base 3, and and hinge cup 2 between be provided with outer articulated elements 9 and interior articulated elements 4, outer articulated elements 9 is hinged with the last installation shaft and the following installation shaft of pivoted arm 1 respectively with interior articulated elements 4.Last installation shaft is provided with spring 5, and an end of spring 5 withstands on outer articulated elements 9 outer walls, and the other end withstands on the fixed axis of pivoted arm 1.Have cavity on the base 3, be provided with buffer in the cavity.Buffer comprises sealed at both ends cylinder body 6, piston rod 7 and piston 8, and wherein the tail end of cylinder body 6 and pivoted arm 1 be for being movably hinged, and in order to improve the sealing of cylinder body 6, two ends are equipped with y-shaped ring in cylinder body 6; Piston rod 7 is located in the cylinder body 6, and an end stretches out outside the cylinder body 6, and is movably hinged with interior articulated elements 4; 8 in piston is fixed on the piston rod 7.Have external seal groove 10 on the external surface of piston 8, the both sides of seal groove 10 are along having damping hole 11 and return port 12 on piston 8 axis directions outside, and external seal groove 10 is provided with seal 13.Seal groove 14 in having between piston 8 and the piston rod 7, interior seal groove 14 is positioned on the inner surface of piston 8.In order to guarantee the sealing between piston 8 and the piston rod 7, on interior seal groove 14, be provided with seal 15. Seal 13,15 is O-ring seals.When door leaf cuts out, articulated elements 4 actions in spring 5 drives, piston rod 7 affects protruding down at interior articulated elements 4, because piston 8 external seal grooves 10 and interior seal groove 14 are equipped with seal, the damping oil of cylinder body 6 one sides can only flow to opposite side by damping hole 11, because damping hole 11 diameters are very little, piston rod 7 outwardly directed speed have been limited, thereby interior articulated elements 4 is around the velocity of rotation reduction of installation shaft down, make that the door leaf closing speed is slack-off, effectively prevent to crush a hand because of the door leaf closing velocity is too fast.When door leaf was opened, articulated elements 4 resetted in spring 5 drove, and piston rod 7 slides in the cylinder body 6.Damping oil flows to opposite side by return port 12, and return port 12 diameters are bigger, and it is very little that piston rod 7 enters the damping action that cylinder body 6 is subjected to, thereby interior articulated elements 4 is unaffected around the velocity of rotation of installation shaft down, and door leaf can be opened fast.
