Abstract
The utility model relates to a wind-proof door closer. The utility model relates to an invention of the working structure of the door closer and the improvement of the opening positioning device. The utility model comprises a dynamic return device arranged in a casing; a sliding work rod (1) of the dynamic return device can hinge a connecting rod (2); the connecting rod (2) can hinge a work block (3); the work block (3) is arranged on the casing by a shaft and a bearing; a swinging block (4) which is positioned at the outer part of the casing and is fixedly connected with the work block (3) is provided with a door-closing connecting rod (5); the door-closing connecting rod (5) is movably connected with a movable sleeve (6); the movable sleeve (6) can hinge a fixed frame (7). The designed door closer according to the utility model not only has the door closing function, but also has the wind-proof and positioning action. The utility model has the advantages of simple structure, convenient installation, and long service life.
Description
The utility model belongs to the improvement invention of door closer.
In the prior art, existing multiple structure on the power return mechanism market of door closer, as the formula of surging, pneumatic type, mechanical type etc., technique effect is more satisfactory, and just the crank structure more complicated of its return of closing the door is long as crank, influence the effect of closing the door, the long-term use damaged easily.Moreover the door closer of market circulation does not mostly have the positioning and wind preventing structure, and is easy to use in order to pass in and out sometimes, need open a period of time to door, but most of door closer structures are not all accomplished this point, bring many inconvenience.
In view of the shortcoming that prior art exists, the utility model aims to provide a kind of door closer that is provided with connecting rod crank mechanism, closes the door to reach, the purpose of windproof location.
The utility model is to finish as follows: a kind of windproof door closer, comprise and be provided with the power return mechanism in the housing, the slip working beam and the rod hinge connection of described power return mechanism, connecting rod and operation block are hinged, operation block is arranged on the housing by axle, bearing, be positioned at the outer swinging block of fixedlying connected with operation block of housing and be provided with and close a connecting rod, this closes a connecting rod and survives with movable sleeve and be connected, and movable sleeve and fixed mount are hinged; Described swinging block is provided with the bar cover, bar cover with close a connecting rod and cooperate, the shell wall that bar overlaps is provided with adjustment screw and is fixed; Be provided with connecting pin between described operation block and the swinging block, the arc-shaped slot that matches with connecting pin is arranged on the housing.
Press the windproof door closer of the utility model theme design, simple in structure, windproof positioning function is superior, long service life.
The utility model has following accompanying drawing
Fig. 1 is a front view of the present utility model
Fig. 2 is a vertical view of the present utility model
Fig. 3 is user mode figure of the present utility model
Accompanying drawing has been represented structure of the present utility model, below in conjunction with accompanying drawing embodiment is described in further detail: comprise being provided with the power return mechanism in the housing, power return mechanisms such as the formula of surging, pneumatic type, mechanical type are arranged.The utility model adopts slip working beam (1) to cooperate with back-moving spring, slip working beam (1) is hinged with connecting rod (2), connecting rod (2) is hinged with operation block (3), operation block (3) is arranged on the housing by axle, bearing, being positioned at the outer swinging block (4) of fixedlying connected with operation block (3) of housing is provided with and closes a connecting rod (5), this closes a connecting rod (5) and survives with movable sleeve (6) and be connected, movable sleeve (6) is hinged with fixed mount (7), described housing is fixedly installed on the doorframe, and fixed mount fixedly installs on the door.Described swinging block (4) is provided with bar cover (8), bar cover (8) with close a connecting rod (5) and cooperate, the shell wall of bar cover (8) is provided with adjustment screw (9) and is fixed, so just can reach to adjust and close a length of connecting rod work, to adapt to the installing and locating of different door with doorframe by adjustment screw (9).Be provided with connecting pin (10) between described operation block (3) and the swinging block (4), the arc-shaped slot (11) that matches with connecting pin (10) is arranged on the housing, and the setting of the shape of arc-shaped slot (11), length, width should adapt with the working condition of connecting pin (10).Simultaneously, this arc-shaped slot (11) is to the limited tailor-made usefulness of the operating angle of swinging block (4).When door closer uses, under the returning spring effect of power return mechanism, reach application target.When the closing a connecting rod and be opened to a certain degree of door closer, when promptly door is opened to required angle, when crank-link mechanism enters the self-locking position just, realize windproof positioning function, when needs at closing time, one group at door, under the effect of spring restoring force, close automatically.
