The specific embodiment
To combine accompanying drawing and embodiment that the utility model is done further detailed description below:
Shown in Fig. 1 to 4; It is a kind of door hinge with pooling feature, and it comprises shell 8 that inner casing and base can be installed, be fixed on hinge pot 1 on the door-plate, first rotating shaft 4, second rotating shaft 12, the 3rd rotating shaft 6, " U " shape rotating shaft 13, connector 2, moving part 3, back-moving spring 5, oil hydraulic cylinder snubber 9 and the impeller 7 that is rotationally connected with oil hydraulic cylinder snubber 9; Wherein impeller 7 is rotationally connected with shell 8 through the 3rd rotating shaft 6, and what oil hydraulic cylinder snubber 9 rotated is located on the shell 8; Connector 2 one ends are rotationally connected through first rotating shaft 4 and shell 8, and the other end through " U " shape rotating shaft 13 one and hinge pot 1 are rotationally connected; One end of moving part 3 is rotationally connected with shell 8 through second rotating shaft 12, and the other end is rotationally connected with hinge pot through another axle of " U " shape rotating shaft 13; Back-moving spring 5 is set in first rotating shaft 4; Oil hydraulic cylinder snubber 9 is rotationally connected through bearing pin 10 and impeller 7; The utility model characteristics are on said moving part 3, to be provided with briquetting 31, and described back-moving spring 5 is a torsion spring, and the card base 52 at torsion spring middle part cooperates with briquetting 31, and the card base 51 at torsion spring both ends is resisted against respectively on two walls of shell 8; Described impeller 7 is a frame section; On two walls of impeller 7, be provided with elongated hole 71, the longitudinal axis L of said elongated hole 71 and the 3rd rotating shaft 6 are provided with two linking arms 32 on moving part 3 on a radial line; Said two linking arms 32 cooperate with two walls of impeller 7; In elongated hole 71, be provided with relatively turnable driving bearing pin 11, the two ends of said driving bearing pin 11 are rotationally connected with two linking arms 32 respectively, and the length of elongated hole 71 can be arranged in hinge pot 1 with the end that guarantees shell 8.
When door was opened, briquetting 31 was pressed onto the end with the card base 52 at torsion spring middle part, and briquetting 31 and the state that card base 52 forms greater than 90 degree are realized self-locking, and at this moment, hinge pot 1 is can be among a small circle in free movable and can closure.When door was closed, under external force, hinge pot 1 was rotated around " U " shape rotating shaft 13; Connector 3 begins along with the swing of " U " shape rotating shaft 13 to rotate, and the briquetting 31 above the moving part 3 also rotates along with the rotation of moving part 3, when briquetting 31 turns to along with moving part 3 under briquetting 31 and the state of card base 52 formation less than 90 degree; The reaction force of back-moving spring 5 is stirred briquetting 31, makes moving part 3 rotate, and moving part 3 drives hinge pot 1 and rotates; At this moment, hinge pot 1 need not be borrowed the external force effect and begun auto-closing, and the driving bearing pin 11 that is fixed on simultaneously on the connector 3 slides in the elongate slots 71 of impeller 7; When driving bearing pin 11 slided into elongate slots 71 stress points of impeller 7, impeller 7 began to rotate, through bearing pin 10 pulling oil hydraulic cylinder snubbers 9; Under the effect of oil hydraulic cylinder snubber 9, hinge pot 1 slow even velocity is closed, up to complete closure; This moment, card base 52 was pushed down the side of briquetting 31, made hinge pot 1 that bigger closing force arranged.
In the present embodiment, for the intensity of reinforced company's moving part 3, on moving part 3, be provided with reinforcing rib position 33.
