Abstract
The utility model discloses a novel hydraulic damping door closer belongs to door and window five metals technical field, including door closer body, driving lever, the driven lever that adopts compressed gas as energy storage device, the bent axle fixed connection on the door closer body is connected with the rotation to the driving lever, and the driving lever is articulated with the driven lever, and the driven lever AND gate body is articulated, and is provided with hydraulic damper on the driven lever, the bent axle passes through connecting rod formation transmission with the piston to be connected, and the piston forms confined piston chamber with the body shell, and the piston intracavity is full of compressed gas as energy storage device. The utility model discloses can realize steadily opening and closing of a body, reduce and strike and the collision, prolong a life -span of the body, and simple structure, it is convenient to maintain, and occupation space is less.
Description
Technical field
The utility model relates to door and window hardware technical field, is specifically related to a kind of novel hydraulic damping door closer.
Background technology
Existing door closer is mainly based on hydraulic door-closer, and basic building block comprises supporting guide, travelling gear, back-moving spring, one way valve, tooth bar plunger, throttling valve core and housing, end cap, sealing ring and connecting rod.Usually, by travelling gear, back-moving spring, one way valve, tooth bar plunger, throttling valve core concentrated setting in housing, then realize the automatic closedown of door body by connecting rod, complex structure, fault rate is high.
Publication number be CN203640468U patent document discloses a kind of hydraulic damp door closer, damage because of clashing into prevent door leaf and doorframe, ensure the stable closedown of door body, driving lever in door closer is arranged to hydraulic damper, and roller is set at auxiliary rod end, arrive the minimum destruction of opposite house body.But be arranged on driving lever by hydraulic damper, and driving lever and door closer body adopt is be fixedly connected with, this will cause driving lever to there is stressed problem, namely there is a moment of flexure on driving lever, affects the performance of hydraulic damper, reduction of service life.
Summary of the invention
The purpose of this utility model is to provide a kind of novel hydraulic damp door closer, and its structure is optimized simply more, and fault rate is lower.
For realizing the utility model object, the technical scheme adopted is: a kind of novel hydraulic damping door closer, it is characterized in that, comprise door closer body, driving lever, follower lever, described door closer body comprises housing, be provided with piston in housing, piston and inner walls form plunger shaft, rotate 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, described driving lever one end is fixedly connected with power transmission shaft, the other end and described follower lever hinged, follower lever arranges hydraulic damper, and follower lever is provided with a body hinged end.
Further, in described plunger shaft, Compressed Gas is nitrogen.
Further, the power transmission shaft on described housing is bent axle.
Further, described power transmission shaft 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 Compressed Gas replaces spring as energy storage component, simplifies the structure; Use crankshaft and piston as transmission mechanism, more simple and reliable compared with traditional rackwork; Follower lever arranges hydraulic damper, making Compressed Gas discharging when the potential energy that gathers closes body more steady, avoiding a body to damage because of collision.And hydraulic damper is arranged on follower lever, two ends respectively at follower lever and door body hinged, follower lever is made to become two power bars, namely door body is when opening or closing, hydraulic damper stressed all the time along follower lever direction tension or pressurized, by the performance of hydraulic damper to better, its life-span can be extended.
Accompanying drawing explanation
Fig. 1 is a kind of novel hydraulic damping door closer schematic diagram that the utility model provides;
Fig. 2 is the body sectional drawing of a kind of novel hydraulic damping door closer 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 a kind of novel hydraulic damping door closer that the utility model provides, and comprises body 1, driving lever 2, follower lever 10; Fig. 2 shows the structure of door closer body, and door closer body 1 comprises bent axle 5, shell 6, plunger shaft 7, connecting rod 8 and piston 9.Door body 4 is hinged with follower lever 10 one end, follower lever 10 is arranged hydraulic damper 3, the other end and the driving lever 2 of follower lever are hinged, what bent axle 5 rotated is connected on shell, one end of bent axle 5 is stretched out body 1 and is fixedly connected with driving lever 2, the plunger shaft 7 that shell 6 is closed with piston 9 stroke, piston 9 is connected with transmission of crankshaft by connecting rod 8 with bent axle 5; Be full of Compressed Gas in plunger shaft 7, as preferably, Compressed Gas selects safety, free of contamination nitrogen.
When door body 4 is opened, moment when being opened by door body 4 by follower lever 10 and driving lever 2 is delivered on bent axle 5, what bent axle 5 was formed by connecting rod 8 is in transmission connection, torque axis is changed into along connecting rod thrust, promote piston 9 to move, the compressed air in plunger shaft 7 compresses further, and volume reduces, pressure increase, potential energy increases.When acting on after the external force on a body 4 removes, releasing energy in plunger shaft 7, promoting piston 9, to make on bent axle 5, because the promotion of connecting rod 8 produces the moment of rotating, to drive driving lever 2, follower lever 10, a body 4 is closed.When door body 4 opens or closes, the hydraulic damper 3 on follower lever 10 can play cushioning effect, avoids a body 4 to be subject to violent shock.
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.
