Abstract
The invention discloses a door closer. The door closer is provided with a fixed support, wherein the head of the fixed support is rotatably connected with a linked crank arm, the internal cavity of the fixed support is provided with a hydraulic cylinder, the head of the hydraulic cylinder is connected with an adjusting shaft fixedly arranged on the linked crank arm, the tail of the hydraulic cylinder is fixedly connected with the fixed support, and the head of the linked crank arm is provided with a rubber bump wheel; the fixed support is provided with a fixed hole; the tail of the hydraulic cylinder is fixedly connected with the fixed support by virtue of a locating pin, and a rubber idler wheel is fixedly connected with the linked crank arm by virtue of the locating pin; and the head of the hydraulic cylinder is fixedly connected with the adjusting shaft by virtue of bolts. The door closer disclosed by the invention has the advantages that the door closer is of a hydraulic type, force strength can be adjusted according to different occasion requirements, a door frame and decorations arranged on the door frame, such as glass, are effectively protected, safety is high, and the door closer is easy to popularize.
Description
Technical field
The present invention relates to a kind of closing device, especially relate to a kind of door closer.
Background technology
General door because individual's dynamics is different, can door frame cause certain damage in the course of time when closing, for the door that glass is installed, maybe be because door closer not to be installed, and effort to close is excessive may shake glass bad; And after sometimes door is unlocked, can not be closed to initial position accurately, timely.Existing door closer is spring structure mostly, and this door closer can not be regulated the size of closing a power, has certain limitation.
Summary of the invention
Technical problem to be solved by this invention provides a kind of can the change and closes a door closer of dynamics size.
In order to solve the problems of the technologies described above; The present invention realizes through following technical scheme: a kind of door closer, have fixed support, and said fixed support head rotation is connected with the interlock connecting lever; Be provided with hydraulic cylinder in the internal cavities; The head of said hydraulic cylinder be fixedly installed on the regulating shaft of interlock on the connecting lever and be connected, afterbody is fixedly connected with fixed support, the head of said interlock connecting lever is provided with rubber and hits wheel.
Install for ease, further, said fixed support is provided with fixing hole.
Connection for the ease of between the constituent parts is fixed, and more further, is fixedly connected through alignment pin between said hydraulic cylinder afterbody and the fixed support, is fixedly connected through alignment pin between said rubber roll and the interlock connecting lever.
In order to make things convenient for regulator solution cylinder pressure dynamics size, further, be connected through bolt between said hydraulic cylinder head and the regulating shaft.
Compared with prior art, usefulness of the present invention is: this door closer is a fluid pressure type, can require the strength of adjustment size according to different occasions, effectively protects doorframe and is installed in the decorations such as glass on the doorframe, and is safe, is easy to popularize.
Description of drawings:
Below in conjunction with accompanying drawing the present invention is further specified.
Fig. 1 is a kind of door closer structural representation of the present invention.
Among the figure: 1, fixed support; 2, hydraulic cylinder; 3,6, alignment pin; 4, regulating shaft; 5, interlock connecting lever; 7, rubber hits wheel; 8, fixing hole.
The specific embodiment:
Describe the present invention below in conjunction with the accompanying drawing and the specific embodiment:
A kind of door closer shown in Figure 1; Have fixed support 1, said fixed support 1 head rotation is connected with interlock connecting lever 5, is provided with hydraulic cylinder 2 in the internal cavities; The head of said hydraulic cylinder 2 be fixedly installed on the regulating shaft 4 of interlock on the connecting lever 5 and be connected; Afterbody is fixedly connected with fixed support 1, and the head of said interlock connecting lever 5 is provided with rubber and hits wheel 7, effectively alleviates bump; For the ease of door closer being installed in the doorframe top, said fixed support 1 is provided with fixing hole 8; Be fixedly connected through alignment pin 3 between said hydraulic cylinder 2 afterbodys and the fixed support 1, be fixedly connected through alignment pin 6 between said rubber roll 7 and the interlock connecting lever 5; In order to make things convenient for the dynamics size of regulator solution cylinder pressure 2, be connected through bolt between said hydraulic cylinder 2 heads and the regulating shaft 4.
During installation, through fixing hole 8 door closer is fixedly mounted on the doorframe top, according to demand; Degree of tightness through bolt between screwdriver regulator solution cylinder pressure 2 heads and the regulating shaft 4; And then realize realizing hydraulic cylinder 2 dynamics size variation regulating to closing a dynamics, imitate the protection doorframe and be installed in the decorations such as glass on the doorframe; Safe, be easy to popularize.
It is emphasized that: above only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction; Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
