Abstract
The invention discloses a hydraulic damping door closer, and belongs to the technical field of door and window hardware. The hydraulic damping door closer comprises a door closer body, a driving rod and a driven rod, wherein the door closer body comprises a transmission shaft, a connecting rod, a piston and a housing; the transmission shaft is in rotating connection with the housing; the piston is in transmission connection with the transmission shaft; the piston and the housing form a closed piston chamber in which an energy storing spring is arranged; one end of the driving rod is fixedly connected with the transmission shaft while the other end of the driving rod is hinged with the driven rod; a hydraulic damper and a door body hinging end are arranged on the driven rod. With the adoption of the hydraulic damping door closer, a door body can be smoothly opened and closed, and the impacting and collision can be reduced, so that the service life of the door body can be prolonged; in addition, the hydraulic damping door closer is simple in structure, convenient to maintain, and small in used space.
Description
Technical field
The present invention relates to door and window hardware part technical field, be specifically related to a kind of hydraulic damp door closer.
Background technology
Existing door closer is mainly based on hydraulic door-closer, and basic building block includes supporting guide, travelling gear, back-moving spring, check valve, tooth bar plunger, throttling valve core and housing, end cap, sealing ring and connecting rod.Generally, by travelling gear, back-moving spring, check valve, tooth bar plunger, throttling valve core concentrated setting in housing, then realizing being automatically switched off of door body by connecting rod, fault rate is high.
Documents CN203640468U discloses a kind of hydraulic damp door closer, damage because of clashing into prevent door leaf and doorframe, it is ensured that the stable closedown of door body, the driving lever in door closer is arranged to hydraulic damper, and roller is set at auxiliary rod end, arrive the minimum destruction to door body.But being arranged on driving lever by hydraulic damper, and driving lever uses fixing connection with door closer body, this may result in driving lever and there is stress problem, on driving lever, i.e. there is a moment of flexure, affect the performance of hydraulic damper, reduction of service life.
Summary of the invention
It is an object of the invention to provide a kind of hydraulic damp door closer, its structure more optimizes simply, and fault rate is relatively low.
For realizing the object of the invention, the technical scheme used is: a kind of hydraulic damp door closer, it is characterized in that, including door closer body, driving lever, follower lever, described door closer body includes by power transmission shaft, connecting rod, piston, shell, described power transmission shaft is rotationally connected with shell, described piston is connected with transmission shaft driven, piston constitutes, with shell, the plunger shaft closed, it is provided with energy-stored spring in described plunger shaft, described driving lever one end is fixing with power transmission shaft to be connected, the other end is hinged with described follower lever, hydraulic damper is set on follower lever and follower lever is provided with door body hinged end.
Further, the power transmission shaft on described housing is bent axle.
Further, between described bent axle and connecting rod, connected mode is that sliding bearing is connected.
Further, described connecting rod is connected with the rotating pin that is connected by of piston.
Beneficial effects of the present invention:
Present invention energy-stored spring mates with the external diameter of energy-stored spring as energy storage component, the area of section of plunger shaft, energy-stored spring can be made to be not likely to produce axis cheap；Use crankshaft and piston is as drive mechanism, simpler reliably compared with traditional rackwork；Follower lever arranges hydraulic damper, makes compressed gas more steady when the potential energy of release accumulation is to close door body, it is to avoid door body is damaged because of collision.And hydraulic damper is arranged on follower lever, two ends are hinged respectively at follower lever and door body, follower lever is made to become two power bars, i.e. door body is when opening or closing, the stress of hydraulic damper is tension or in compression along follower lever direction all the time, its life-span can be extended by the performance of hydraulic damper to more preferably.
Accompanying drawing explanation
Fig. 1 is a kind of hydraulic damp door closer schematic diagram that the present invention provides；
Fig. 2 is the body profile of a kind of hydraulic damp door closer that the present invention provides.
Detailed description of the invention
Below by specific embodiment and combine accompanying drawing the present invention is described in further detail.
Fig. 1 shows a kind of hydraulic damp door closer that the present invention provides, including body 1, driving lever 2, follower lever 3；Door closer body 1 comprises power transmission shaft 5, shell 6, plunger shaft 7, connecting rod 8 and piston 9；Door body 4 is hinged with follower lever 3 one end, on follower lever 3, hydraulic damper is set, the other end of follower lever is hinged with driving lever 2, what power transmission shaft 5 rotated is connected on shell, one end of power transmission shaft 5 stretches out that body 1 and driving lever 2 is fixing to be connected, the plunger shaft 7 that shell 6 is closed with piston 9 stroke, piston 9 is connected with transmission shaft driven by connecting rod 8 with power transmission shaft 5；Being provided with energy-stored spring 10 in plunger shaft 7, wherein, the diameter of section of plunger shaft 7 mates with the external diameter of energy-stored spring 10, it is to avoid energy-stored spring 10 produces journal offset under operating mode of stretching frequently.
As preferably, power transmission shaft 5 is bent axle, forms the drive mechanism being similar to automobile engine with connecting rod 8, piston 9.
When door body 4 is opened, moment when door body 4 being opened by follower lever 3 and driving lever 2 is delivered on bent axle 5, bent axle 5 is by being in transmission connection that connecting rod 8 is formed, torque axis is melted into along connecting rod thrust, promoting piston 9 to move, the compressed air in plunger shaft 7 is compressed further, and volume reduces, pressure increases, and potential energy increases.After the external force acted in door body 4 is removed, release energy in plunger shaft 7, promote piston 9 so that produce, because of promoting of connecting rod 8, the moment rotated on bent axle 5, drive driving lever 2, follower lever 3, make door body 4 close.Door body 4 opens or closes when, the hydraulic damper on follower lever 3 all can play cushioning effect, it is to avoid door body 4 is by violent shock.
The foregoing is only the preferred embodiment of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
