Description

The hydraulic pressure door closer

Technical field

The utility model relates to makes wing move to the device of unlatching or fastening position, relates in particular to the fluid pressure type door closer.

Background technology

Family and office's door leaf are artificial hand push mostly and close at present, and door is opened the back and fixed or remove the chair roof door with the magnetic-type door-inhale, and is cumbersome and fixing not firm, easily moved by wind.Existing door check great majority are by the elastic recovering force of spring door to be closed automatically, and the shortcoming of this mode is that door fits badly when spring is weak; When elasticity was strong, impact force was very big, and impact sound is very loud, damaged doorframe easily.People have further developed the fluid pressure type door closer again, as Chinese patent 92228037.1 " automatic door closer ", by the damping force to oil return, make a process of closing steady, do not have bump, noiselessness; After but this door closer is opened door, be difficult for door locked when wind-force is excessive, door to be blown the pass in stable state.

Summary of the invention

The purpose of this utility model is to provide a kind of door is opened to 90 when spending, and door stops motionless automatically; When pushing open to 100 degree positions again, door is closed again automatically; And the switching process of door is steady, reliable, no impact noise.

The purpose of this utility model is achieved in that

The utility model hydraulic pressure door closer has a hydraulic pushing device, comprises cylinder body, flexible plug, spring, anti-leakage pad housing pin, antiseepage rubber cushion, inner chamber lid; Be filled with hydraulic oil in the inner chamber of cylinder block, oil-in is arranged on the cylinder body, have cap nut to open and close on it; Slidably, spring is placed in the flexible plug in inner chamber of cylinder block for the flexible damping hole that has beyond the Great Wall, flexible plug.The activity of flexible plug is exerted pressure to spring.

The end in contact on top and the transmission montant of stretching out of stretching plug is transmitted motive force mutually; Transmission montant lower end is plugged in the transmission montant seat, can rotate within it.

The utility model hydraulic pressure door closer also has the door leaf locator, comprises horizontal drawing plate, bent arm-tie, slide-bar, shifting axle, impeller-hub; Horizontal drawing plate one end is connected with impeller-hub, and an end is connected with shifting axle, bent arm-tie one end cover slide-bar, and slide-bar can slide in the slide-bar groove on internal frame, and the bent arm-tie other end has a chute, and shifting axle can slide in groove.Have an axis hole on the transmission montant, impeller-hub passes this axis hole and transmission montant and realizes being rotationally connected, and the motive force or the hydraulic pressure thruster spring restoring force of door passed to the door leaf locator; Transmission montant top also has vertical core, communicates with above-mentioned axis hole is vertical, and built-in pearl, the spring of bumping compresses with a bolt.There is half garden recess in the impeller-hub stage casing, and the horizontal drawing plate can make impeller-hub and horizontal drawing plate rotate with the connected mode of impeller-hub, and when forwarding an ad-hoc location to, half garden recess bumps pearl and can fall in the recess just up, hinders the impeller-hub rotation.

Hydraulic pushing device and door leaf locator all are placed in the internal frame, and internal frame is made by metal material, and it has: front end-plate, front end bayonet socket, rear end bayonet socket, arm-tie platform, median septum, end plate, base plate, slide-bar groove, transmission montant shifting chute, side shaft seat.

Other has an installing plate, and the installation screw is arranged on it, is used for installing plate is fixed on upper door frame.The side shaft seat is arranged on the installing plate.By side shaft, form hinge with side shaft seat on the internal frame and be connected.

Transmission montant seat is placed in door leaf back.When door was pushed, door leaf rotated around door-hinge, and the device of remaining silent rotates around side shaft, and the active force that pushes is shunk back the flexible plug of hydraulic pushing device by the transmission montant and made length of spring compressed.In case the active force that pushes disappears, and under the elastic restoring force effect of spring, door leaf cuts out naturally.Hydraulic oil in the hydraulic pushing device inner chamber of cylinder block flows by flexible damping hole beyond the Great Wall, and the release of the energy of spring is hindered, thereby makes the action of closing the door obtain buffering.Can lead to change damping hole size and quantity during design, reach different buffering effects.

When door leaf cut out, shifting axle snapped in front end bayonet socket on the internal frame, and door is closed very firmly, and this moment, horizontal drawing plate and bent arm-tie all were in lead position.When door leaf was pushed, the transmission montant moved after in transmission montant groove, and impeller-hub drives the horizontal drawing plate, make shifting axle from the front end bayonet socket, thereupon, slide-bar and bent arm-tie all move backward, and slide-bar arrives slide-bar groove rear end, shifting axle arrives bent arm-tie corner top, spur bent arm-tie and rotate backward around slide-bar, and then make shifting axle fall into rear end bayonet socket on the internal frame, this moment, door leaf left to 90 degree, because of shifting axle is stuck, door leaf is fixed at 90 degree.

When door leaf need cut out again, again door leaf is pushed open from 90 degree, the transmission montant with after move, by the horizontal drawing plate, make shifting axle leave the rear end bayonet socket, when door leaf reaches 100 when spending, the flexible plug of pusher has been compressed to position, the end, shifting axle moves to bent arm-tie front top from bent arm-tie corner end, and impeller-hub forwards an ad-hoc location at this moment to, and the spring at transmission montant top will bump the half garden recess that pearl is pressed into the impeller-hub stage casing, impeller-hub is not temporarily rotated, thereby push when stopping, shifting axle can not fall into the rear end bayonet socket again, and pusher spring restoring force is stretched out flexible plug.By transmission montant and transmission montant seat door leaf steadily cuts out.In this process, impeller-hub, transmission montant are subjected to stretching out of the flexible plug of pusher and move forward, and by horizontal drawing plate promotion shifting axle, shifting axle drives bent arm-tie, and bent arm-tie pulling slide-bar moves forward in the lump, when slide-bar arrives the slide-bar front of the slot, bent arm-tie rotates forward around slide-bar under the promotion of shifting axle again, since bent arm-tie forward, downward rotation, the pressure that makes impeller-hub overcome spring latch lock rotates simultaneously, impeller-hub leaves above-mentioned ad-hoc location.Finally, shifting axle falls back to again in the front end bayonet socket, and each parts of door closer are got back to and closed a position.

According to above principle, can be according to different effect requirements, when door closer design and manufacturing, the set positions that the door leaf unlatching can be located and close again is on other angle.

The utility model excellent working performance, door leaf cuts out tight, opens firm position, closes the door automatically steadily, and is rational in infrastructure reliable.
