The utility model speed of closing the door is mild, promptly is that the speed of closing the door early stage is slow, and the later stage speed of closing the door is accelerated a little, and does not produce big sound at closing time, avoids wind that door leaf is patted doorframe, can shield to door leaf and doorframe, and automatically door be closed tight.It is simple in structure, stable and reliable working performance.
Four, description of drawings
Below in conjunction with accompanying drawing structure of the present utility model is further described:
Fig. 1, be structural representation of the present utility model.
Five, the specific embodiment
In the drawings, the utility model door closer comprises slide cartridge (3), guide rod (4), spring (5), piston (6), spacing card pad (10) and Connection Block A (1), Connection Block B (9).Piston (6) is in slide cartridge (3), one end of guide rod (4) is fixed on the piston (6), and its other end passes the outside of slide cartridge (3) left end and be connected with Connection Block A (1) by straight pin A (2), spring (5) is enclosed within on the guide rod (4), its two ends be separately fixed at that piston (6) is gone up and the end cap inwall of slide cartridge (3) left end on, the exposing partly to be positioned at of guide rod (4) is with between straight pin A (2) and slide cartridge (3) left end and can carries out spacing spacing card pad (10) to guide rod (4), slide cartridge (3) right-hand member is connected in Connection Block B (9) by straight pin B (7), the design of the right-hand member of slide cartridge (3) be useful on the air of discharging slide cartridge (3) and regulate the pore of discharged air flow and on this pore the corresponding regulating the qi flowing in the channels screw (8) that is equipped with, in inwall design the boss that sticks out is arranged near slide cartridge (3) right-hand member.When the utility model is installed, Connection Block A (1) and Connection Block B (9) are separately fixed on door leaf and the doorframe.When using-and this is door opening state: guide rod (4) drives piston (6) and moves to slide cartridge (3) left end, spring (5) is compressed, the people leaves after this door, spring (5) tension force promotes piston (6) and moves to slide cartridge (3) right-hand member, drive by guide rod (4), by guide rod (4) by being installed in Connection Block A (1) on the door leaf door is closed-this is for closing the door state: in the process of piston (6) motion, air in the compression slide cartridge (3), and the air between slide cartridge (3) inner carrier (6) and slide cartridge (3) right-hand member can only outwards be discharged gradually and on a small quantity by the pore of slide cartridge (3) right-hand member, therefore, air pressure between slide cartridge (3) inner carrier (6) and slide cartridge (3) left end is high slightly, so spring (5) resets slowly, correspondingly, close the door and also can only carry out gently, when piston (6) is crossed the lug boss position of close slide cartridge (3) right-hand member, owing to slide cartridge (3) inner carrier (6) right side hyperbar air cross piston (6) flow to its left side air pressure on slide cartridge (3) inner carrier (6) right side is plunged, be the pressure moment increasing of propelling piston (6) to the motion of slide cartridge (3) right-hand member, the later stage speed that close the door this moment is accelerated a little, thereby door is firmly closed tight.
