Abstract
The utility model discloses a kind of door closer stored energy mechanism, relate to door and window hardware technical field, comprise bent axle, connecting rod, piston, housing, plunger shaft, Compressed Gas, the gas rotating through the motion compresses plunger shaft of connecting rod and piston when door body is opened by bent axle, reach the object of energy storage, after the external force on door-plate is removed, the gas push piston in plunger shaft, piston makes crank rotation by connecting rod, reaches and a body is closed automatically.The energy storage that door-plate rotates gets up by the utility model effectively, changes traditional spring energy agency, makes whole door closer structure more simply compact.
Description
Technical field
The utility model relates to door and window hardware device technical field, is specifically related to a kind of stored energy mechanism of door closer.
Background technology
The existing door that closes adopts spring as stored energy mechanism more, when opening the door, and the action of door body drivening rod, and travelling gear is rotated, drive tooth bar plunger to move to the right.In the process that plunger moves to right, spring is compressed, storage power; After door opening action completes, the elastic potential energy release that spring is put aside, band nutating gear and door closer link rotatable, make a closedown.
When adopting this spring as stored energy mechanism, due to spring release energy uneven, the hydraulic oil of buffer damping of generally all arranging in pairs or groups, causes whole door closer structure too meticulous numerous and diverse, and volume is comparatively large, and fault rate is higher.
Utility model content
It is simple that the purpose of this utility model is to provide a kind of structure, the door closer stored energy mechanism that unitary construction is light.Its simple and clear structure greatly reduces the fault occurrence probability of door closer, and storage power is more steady with the process released energy.
For realizing the utility model object, the technical scheme of employing is: a kind of door closer stored energy mechanism, is characterized in that, comprise housing, be provided with piston in housing, and piston and inner walls form plunger shaft, rotates and be provided with power transmission shaft in housing; Described power transmission shaft is connected with connecting rod, and is connected with piston drive by connecting rod, has Compressed Gas in described plunger shaft.
Further, in described plunger shaft, Compressed Gas is nitrogen.
Further, the power transmission shaft on described housing is bent axle.
Further, described bent axle and connected mode between connecting rod are that sliding bearing is connected.
Further, the connection of described connecting rod and piston adopts rotating pin to connect.
The beneficial effects of the utility model:
The utility model enormously simplify door closer stored energy mechanism, reduces the probability of failure of door closer, makes stored energy mechanism storing, more steady when releasing energy simultaneously.
Accompanying drawing explanation
Fig. 1 is the door closer stored energy mechanism generalized section that the utility model provides.
Detailed description of the invention
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
Fig. 1 shows the stored energy mechanism of a kind of door closer that the utility model provides, door closer stored energy mechanism, comprises the housing 2 that inside is formed with plunger shaft 3, described housing 2 is rotatably connected to power transmission shaft 1, and power transmission shaft 1 to be in transmission connection piston 5 by connecting rod 4; Wherein, power transmission shaft 1, connecting rod 4 and piston 5 define a transmission mechanism, as preferably, power transmission shaft 1 adopts bent axle, in order to the connection of bent axle and connecting rod 4 is become more flexible, to greatest extent less because of friction off-energy, this syndeton being set to sliding bearing and connecting, had been both sliding bearing in one end that connecting rod 4 is connected with bent axle; Because its rotational angle is less between connecting rod 4 and piston 5, the energy of friction loss can accept, therefore the rotating pin adopted between connecting rod 4 with piston 5 is connected; In order to increase the shift motion of piston 5, described plunger shaft 3 is arranged to " recessed " type, and under the prerequisite that storage of potential energy total amount remains unchanged, piston 5 has longer stroke.Compressed air suits 6 in described plunger shaft, as preferably, Compressed Gas 6 selects nitrogen.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
