Angle chain type electric window-opening machine
Technical field
The present invention relates to a kind of Chain-type electric window opening machine that is used for opening and closing windows.
Background technology
Original Chain-type electric window opening machine, the patent No. are ZL200420026983.8.Chain generally can only be accomplished the vertical operation of chain and fuselage, and the warping resistance of its chain mainly is to rely on the installation accessories of chain ends to realize, but some forms can't be used this type.Though general electric window-opening machine also can be realized unlatching at an angle when entity is installed, but owing to there is not the effect of external force, the easy bending of chain in running, chain arrives when desired location is in inactive state also can't keep the linearity of chain, thereby the unlatching that can't play forms keeps effect.
Summary of the invention
Existing electric window-opening machine warping resistance effect is bad in order to overcome, unlatching keeps the effect defect of bad, the invention provides a kind of angle chain type electric window-opening machine, this angle chain type electric window-opening machine can be realized the operation under chain and the non-perpendicular state of window opening device fuselage, played the effect of warping resistance simultaneously, satisfied of the application of those special forms window opening device.
Technical scheme of the present invention is: this angle chain type electric window-opening machine comprises main frame, main frame is connected with auxiliary body, auxiliary body comprises housing and spring, spring is positioned at housing, spring rear end is connected with bonnet, and the spring front end is connected with slide block, and slide block is positioned at protecgulum and can slides at protecgulum, guide pad lower end and protecgulum lower end are movably connected by bearing pin, and guide pad rear end and slip front are inconsistent.
During installation, guide pad directly tangentially is connected with the chain of window opening device, keeps the linear state of chain between window opening device main frame and auxiliary body, plays the effect that prevents the chain bending.The logical bearing pin of guide pad is connected the drive end bearing bracket place, realizes swaying under the effect of power source spring, realizes the angle operation of guide pad, and chain has also been realized the motion of non-perpendicular state simultaneously.Chain can warping resistance when static under the effect of guide pad.
Advantage of the present invention: auxiliary body is pure frame for movement, and power resources are in the elastic potential energy of spring.Energy-saving and environmental protection, safety also make electric window-opening machine realize a tractor serves several purposes, have expanded the range of application of window opening device.Be mainly used in Chain-type electric window opening machine, can realize of the application of how special forms electric window-opening machine.The position that goes out chain mouth (indentation, there that chain comes out from the machine internal operation) at original chain type electric window-opening device applies the external force of its traffic direction of control to chain. and after chain is static, can keep the inactive state of chain, prevent that the bending of chain from influencing the unlatching effect of forms.
