Abstract
The utility model relates to an inserting automatic door closing device, which is composed of a host, a pull nail, and a bent lever, wherein, the host is inserted inside the lateral wall of a doorframe, the pull nail is fixed at the appropriate place of the lateral wall of a door leaf corresponding to the host, and the bent lever is connected with the host and the pull nail. When the door leaf rotates, the bent lever and the pull nail can get into and get out the host flexibly; when the door leaf closes, the bent level and the pull nail get into the host completely. Any part of the automatic door closing device is not exposed, and the closing velocity of the door leaf can be changed by adjusting the buffering of a cushion cylinder inside the host.
Description
The utility model relates to a kind of automatic door closer.
Present widely used door closer is made up of main frame and linkage, main frame is fixed on door leaf top, linkage one end is installed in doorframe top, and the other end links to each other with the output shaft of main frame, and the weak point of existing door closer is that profile is not beautiful, structure backwardness, easy oil leakage, fragile.
The purpose of this utility model provides a kind of good looking appearance, novel structure, dependable performance, long-lived automatic door closer.
The utility model is achieved in that the flush type automatic door closer is by main frame, blind rivet, curved bar three parts are formed, main frame is inlaid in the doorframe lateral wall, blind rivet is fixed on door leaf lateral wall and the corresponding appropriate location of main frame, the interchangeable installation site of main frame and blind rivet, curved bar connects main frame and blind rivet, when door leaf rotates, curved bar and blind rivet can advance neatly, go out main frame, after door leaf cuts out, curved bar and blind rivet all enter in the main frame, and any part of automatic door closer does not all expose, when opening door leaf, people's active force withdraws from main frame by door leaf lateral wall towing blind rivet and curved bar, drive the back-moving spring compression in the main frame, after door leaf is opened, in case people's active force is removed, the restoring force of back-moving spring is that towing curved bar and blind rivet enter main frame in the main frame, the drive door leaf cuts out, and is equipped with in the main frame and the synchronization-moving cushion cylinder of back-moving spring, adjusts the damping of cushion cylinder, can change the speed that curved bar and blind rivet enter main frame, thereby change the closing velocity of door leaf.
The utility model compared with prior art has hidden, good looking appearance, dependable performance, advantage such as not fragile is installed, and can be widely used in the vertical hinged door that various needs are closed automatically.
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail:
Fig. 1 is the utility model mounting means schematic diagram.
Fig. 2 is the structure chart of the utility model most preferred embodiment.
Main frame (3) is by housing (4), traction plunger (5), back-moving spring (6), cushion cylinder (10), coupling bar compositions such as (8), three parallel circular holes are arranged on housing (4), traction plunger (5), back-moving spring (6), cushion cylinder (10) is assemblied in respectively in these three circular holes, traction plunger (5), back-moving spring guide rod (7), the end of cushion cylinder cylinder body (9) is all hinged with coupling bar (8), because the effect of coupling bar (8), traction plunger (5), back-moving spring (6), the motion of cushion cylinder (10) in housing (4) is synchronous, the piston (14) of cushion cylinder (10) is fixed on the housing (4), one way valve (11) and throttle orifice (12) are arranged on the piston (14), when contracting in the cushion cylinder (10), the hydraulic oil of rodless cavity by one way valve (11) undamped enter rod chamber, so cushion cylinder (10) contracts in can be fast, when cushion cylinder (10) is overhanging, one way valve (11) is closed, the hydraulic oil of rod chamber damping is arranged enters rodless cavity through throttle orifice (12), it is slower when so cushion cylinder (10) is overhanging, rotate adjustment screw (13), can change the damping of throttle orifice (12), thereby change the overhanging speed of cushion cylinder (10), when the flush type automatic door closer uses, main frame (3) is inlaid in the doorframe lateral wall, blind rivet (1) is fixed on door leaf lateral wall and the corresponding appropriate location of main frame (3), curved bar (2) is hinged with traction plunger (5) and blind rivet (1) on the main frame (3), when door leaf rotates, curved bar (2) and blind rivet (1) can advance neatly, go out main frame (3) and go up the circular hole at traction plunger (5) place, after door leaf cuts out, curved bar (2) and blind rivet (1) all enter the circular hole at traction plunger (5) place, the any part of automatic door closer does not all expose, when opening door leaf, people's active force withdraws from main frame (3) by door leaf lateral wall towing blind rivet (1) and curved bar (2), drive outside the traction plunger (5) and move, by coupling bar (8), make in back-moving spring (6) compression and the cushion cylinder (10) and contract, because undamped when contracting in the cushion cylinder (10), so door leaf can be opened fast, after door leaf is opened, in case people's active force is removed, the restoring force of back-moving spring (6) promptly by move in coupling bar (8) the towing traction plunger (5) and cushion cylinder (10) overhanging, moving curved bar (2) of the interior shipper pole of traction plunger (5) and blind rivet (1) enter in the main frame (3), door leaf cuts out, cushion cylinder (10) has damping when overhanging, overhanging speed is slower, so limited the closing velocity of door leaf, rotate adjustment screw (13), can change the damping of cushion cylinder (10), thereby change the door leaf closing velocity.
Claims (1)
1, a kind of automatic door closer that is applicable to various vertical hinged doors, form by main frame (3), blind rivet (1), curved bar (2) three parts, it is characterized in that main frame (3) is inlaid in the doorframe lateral wall, blind rivet (1) is fixed on door leaf lateral wall and the corresponding position of main frame (3), and curved bar (2) connects main frame (3) and blind rivet (1).
