Abstract
The invention discloses a door closer with a volute spiral spring, and belongs to the technical field of hardware of doors and windows. The door closer with the volute spiral spring comprises a door closer body, a driving rod and a driven rod, wherein the door closer body comprises a transmission shaft and a shell; the transmission shaft is rotatably connected with the shell; the volute spiral spring is arranged on the transmission shaft and is fixedly connected with the shell; one end of the driving rod is fixedly connected with the transmission shaft; the other end of the driving rod is hinged to the driven rod; a hydraulic damper is arranged on the driven rod; and a door body hinged end is arranged on the driven rod. The volute spiral spring is used as an energy storage component, so that the structure of the energy storage component is quite simple and is compact in structure. The hydraulic damper is arranged on the driven rod, two ends of the hydraulic damper are respectively hinged to the driven rod and a door body, so that the driven rod becomes a two-force bar, namely, when the door body is opened or closed, the hydraulic damper is always tensioned or pressed along the direction of the driven rod, the performance of the hydraulic damper can be high, and the service life of the hydraulic damper is prolonged.
Description
Technical field
The present invention relates to door and window hardware part technical field, be specifically related to a kind of scroll spring 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 scroll spring 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 scroll spring door closer, it is characterized in that, including door closer body, driving lever, follower lever, described door closer body includes by power transmission shaft, shell, described power transmission shaft is rotationally connected with shell, it is provided with scroll spring on described power transmission shaft, described scroll spring is fixing with shell to be connected, described driving lever one end is fixing with power transmission shaft to be connected, the other end is hinged with described follower lever, follower lever arranges hydraulic damper and follower lever is provided with door body hinged end.
Further, described scroll spring is arranged on the inside of shell.
Further, described scroll spring has two, is separately positioned on upper wall and the lower wall of shell.
Beneficial effects of the present invention:
Present invention scroll spring is as energy storage component, the structure making energy storage component is extremely simple, compact conformation, and hydraulic damper is arranged on follower lever, two ends are hinged respectively at follower lever and door body so that follower lever becomes 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, can extend its life-span by the performance of hydraulic damper to more preferably.
Accompanying drawing explanation
Fig. 1 is a kind of scroll spring door closer schematic diagram that the present invention provides；
Fig. 2 is the body profile of a kind of scroll spring 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 scroll spring door closer that the present invention provides, including body 1, driving lever 2, follower lever 3；Door closer body 1 comprises power transmission shaft 6, shell 7, scroll spring 5.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 6 stretches out that body 1 and driving lever 2 is fixing to be connected, 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, moment of torsion does work, and stores energy in scroll spring 5, after the external force acted in door body 4 is removed, release energy in scroll spring 5, it is that power transmission shaft 6 rotates, drives 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.
As preferably, scroll spring 5 arranges two, provides more powerful spinning force, the two scroll spring 5 to be arranged in shell 7 for power transmission shaft 6 internal, and upper wall and each one of lower wall, scroll spring 5 is bolted with the inwall of shell 7.
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.
Claims (3)
1. a scroll spring door closer, it is characterized in that, including door closer body, driving lever, follower lever, described door closer body includes that, by power transmission shaft, shell, described power transmission shaft is rotationally connected with shell, and described power transmission shaft is provided with scroll spring, described scroll spring is fixing with shell to be connected, described driving lever one end is fixing with power transmission shaft to be connected, and the other end is hinged with described follower lever, follower lever arranges hydraulic damper and follower lever is provided with door body hinged end.
