Abstract
A novel door closer end cap sealing structure comprises a door closer main body, a spring, a washer and a rear end cap, and is characterized in that the spring, the washer and the rear end cap are arranged in the door closer main body, the washer is arranged outside the rear end cap, the spring is arranged inside the rear end cap, and the spring acts on the rear end cap through pressure inside the door closer main body. A circle of a groove corresponding to the washer is arranged in the outside of the rear end cap. The novel door closer end cap sealing structure has the advantages that the washer is directly arranged in the groove in the rear end cap, and the occasion that assembly is neglected is not prone to occur; and the pressure inside the door closer main body acts on the rear end cap, the rear end cap and the door closer main body are directly tightly pressed, and a sealing effect is achieved.
Description
Technical field
The utility model relates to door closer field, specifically a kind of novel door closer end cover sealing structure.
Background technique
Door closer is a hydraulic pressure device of a upper spring-like, can door be shut automatically by discharging after compression after door is opened, and the effect that resembles swing door is arranged, and after can guaranteeing that door is unlocked, is closed to accurately, timely initial position.The meaning of door closer not only is the door autoshutdown, can also protect doorframe and door body (steadily closing), the more important thing is that door closer has become a very important do-part of modern architecture intelligent management.Door closer mainly is used in business and public building, but situation about using is at home also arranged.They have a lot of purposes, wherein topmost purposes be make the door close voluntarily, limit fire spread with the mansion in ventilation.
The working principle of door closer is: when opening the door, and the action of door body drivening rod, and driving gear is rotated, drive the tooth bar plunger to right-hand movement.The process medi-spring that moves to right at plunger is compressed, and the hydraulic oil in right chamber is pressurized also.The one-way valve spheroid in plunger left side is opened under the effect of oil pressure, and the hydraulic oil in right chamber flows in left chamber through one-way valve.After the process of opening the door was completed, because spring is compressed in opening process, the elastic potential energy of putting aside was released, and with the plunger thruster of turning left, band nutating gear and door closer connecting rod rotate, and door is closed.
The basic building block of door closer has supporting guiding element, driving gear, Returnning spring, one-way valve, tooth bar plunger, throttling valve core and housing, end cap, seal ring and connecting rod.Traditional door closer end cap is all to reach the effect of sealing by the mode of screw thread glue, "O"-ring, and this kind mode often can fill, not tighten the problem that sealing effect lost efficacy that produces because of defective or neglected loading, the mistake of screw thread glue, O type circle.The door closer end cover sealing structure that also there is no at present a kind of simple in structure, good sealing effect.
Summary of the invention
The utility model is for above technical problem, and a kind of simple in structure, easy for installation, door closer end cover sealing structure that sealing effect is good is provided.
The utility model is achieved through the following technical solutions.
A kind of novel door closer end cover sealing structure, comprise door closer main body, spring, packing ring, rear end cover, it is characterized in that spring, packing ring, rear end cover are arranged in the door closer main body, packing ring is arranged on outside rear end cover, spring is arranged on the rear end cover inboard, spring by the pressure-acting in the door closer main body on rear end cover.There is a circle groove corresponding with packing ring in the rear end cover outside.
Innovative point of the present utility model is directly packing ring to be arranged in the groove of rear end cover, is not prone to neglected loading, and passes through the interior pressure-acting of door closer main body on rear end cover, directly rear end cover and door closer main body is compressed, and reaches the effect of sealing.
Description of drawings
In accompanying drawing, Fig. 1 is the utility model structure sectional view, and Fig. 2 is the utility model rear end cover plan view, wherein:
1-door closer main body, 2-spring, 3-packing ring, 4-rear end cover.
Specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of novel door closer end cover sealing structure, comprise door closer main body 1, spring 2, packing ring 3, rear end cover 4, it is characterized in that spring 2, packing ring 3, rear end cover 4 are arranged in door closer main body 1, packing ring 3 is arranged on rear end cover 4 outsides, spring 2 is arranged on rear end cover 4 inboards, spring 2 by the pressure-acting in door closer main body 1 on rear end cover 4.There is a circle groove corresponding with packing ring 3 in rear end cover 4 outsides.
Innovative point of the present utility model is directly packing ring 3 to be arranged in the groove of rear end cover 4, is not prone to neglected loading, and passes through the interior pressure-acting of door closer main body 1 on rear end cover 4, directly rear end cover 4 and door closer main body 1 is compressed, and reaches the effect of sealing.
