The specific embodiment
For the ease of those skilled in the art's understanding, the utility model sky spring is further specified below in conjunction with the accompanying drawing and the specific embodiment:
Shown in accompanying drawing 1-2; A kind of gate is an adjustable day spring comprises valve body 1, in the valve body chamber, has been provided with the cylinder chamber 101 of hydraulic action and the Transmission Room 102 of a gearing; Be provided with two parallel oil cylinders in the said cylinder chamber 101; Be " ∏ " shape between two parallel oil cylinders and the Transmission Room 102 and connect, in Transmission Room and oil cylinder, be provided with the transmission mechanism of forming by the planker of the wheel shaft core 2 that links to each other with door-hinge, socket wheel shaft core, the connecting rod 3 that links to each other with planker, the piston 4 that is located at link end; In Transmission Room and another oil cylinder, be provided with and regulate the dynamics adjustable mechanism that closes an angle.Described dynamics adjustable mechanism by the planker of the wheel shaft core 2 that links to each other with door-hinge, socket wheel shaft core 2, the set screw 5 that links to each other with planker, the regulating piston 6 that is located at the set screw end, be located at regulating piston 6 ends lever regulated bar 7, be located at the adjustable end cap 8 of this oil cylinder end and be socketed in set screw and regulating piston on regulating spring 15 form.The oil cylinder front end that is provided with transmission mechanism is provided with protecgulum 9, and Transmission Room 102 upper walls are provided with the gland 10 of sealing Transmission Room and socket wheel shaft core 2; Described valve body 1, protecgulum 9, adjustable end cap 8, wheel shaft core 2, gland 10 are formed a seal chamber, on the wall of valve body 1, are provided with oil circuit and oil sealing mouth.Between two parallel oil cylinders, be provided with annular oil groove 11, this section valve body is provided with assigns the adjustment valve of regulating the hydraulic-oil quantity size and the hydraulic fluid port that communicates with oil circuit; On valve body 1, also be provided with hydraulic fluid port, quick hydraulic fluid port, oil return opening at a slow speed, be oil circuit between them and be communicated with; Described quick hydraulic fluid port is corresponding with the annular oil groove between two oil cylinders; Be respectively equipped with the hydraulic fluid port adjusting device on described hydraulic fluid port at a slow speed and the quick hydraulic fluid port.Described planker comprise planker 12, down planker 13, be clipped in up and down planker and make the cam 14 of locating behind the door-hinge rotational angle.
When opening the door, door-hinge drives wheel shaft core 2, moves right through 12,13 drivening rods 3 of planker up and down, piston 4 and set screw 5, regulating piston 6, and at this moment the oil on oil cylinder inner carrier 4 the right flows into the piston left side through one way valve, realizes opening the door action.At closing time, door drives a cam 14 rotations, promotes left at the following piston of the effect of spring 4, connecting rod 3; At this moment one way valve sealing, by the laggard oiler of hydraulic fluid port throttling at a slow speed, another part is by the oil sealing mouth of protecgulum 9 in the oil part on the oil cylinder inner carrier left side; Through cannelure again by getting into oil return opening after the quick hydraulic fluid port throttling; Flow into piston the right by oil return opening again, hydraulic fluid port sealing fast, the Men Zaiguan closed procedure is closed the door from closing the door fast to change at a slow speed when piston gets into the oil sealing mouth; The oil on the piston left side receives the compressing of left side piston to buckle the right that the oil return opening of flowing through gets into piston through throttling from hydraulic fluid port at a slow speed, accomplishes and closes soon slowly.At this moment oil receives the effect of hydraulic fluid port throttling at a slow speed, and this all is the effect that receives the flow resistance of oil.Such structure is led to the assurance sealing through the oil phase that the sealing ring on the piston intercepts the piston left side and the right, and also making weares and teares between piston and the cylinder body greatly reduces, and improves application life.The body supporting power is better, and the dynamics of opening the door is lighter, and it is more steady to close a speed.And space mounting is more simple and easy with having saved the station at the top that is installed in door-hinge.
Only need regulate being located at the terminal lever regulated bar 7 of adjustable end cap 8 during adjusting, regulating spring 15 is just along with variation, finely tune out with so just can having no boundary make the user fully satisfaction close a strength, make on the same day the suitable different gate-widths of spring, weigh.
The above is a preferred embodiment of the utility model, and under the situation that does not break away from the utility model inventive concept, any conspicuous distortion and the replacement carried out all belong within the utility model protection domain.
