The top assembly includes lateral upper mounted plate 8, is fixed on the axis of cone set 7 of 8 top of upper mounted plate, is assemblied in cone The top of the axis of cone 6 in axle sleeve 7 and spring 71, the axis of cone set 7 is fixed with door 72;The lower end of the axis of cone 6 downward through Fixed plate 8, and be rectangular pyramid shape in the lower end of the axis of cone 6, at least one lateral wall is equipped with several lateral strip holes 61.It is equipped with spring slot on the top of the axis of cone 6, the lower end of the spring 71 is plugged in spring slot, and top contacts door 72.
The upper element includes that proximate matter upper cover plate 9, fixed welded plate 4 and pneumatic spring 3, the fixed welded plate 4 are solid It is scheduled on the top of pneumatic spring 3, and is fixedly connected with the bottom of proximate matter upper cover plate 9;The middle part of the proximate matter upper cover plate 9 is equipped with upper The channel of lower perforation is equipped with connecting bushing 5 in the channel;As shown in figure 3, the middle through-hole of the connecting bushing 5 is by epicone Hole 51 and lower cone hole 52 form, and the upper taper hole 51 and the lower end of the axis of cone 6 match, the lower cone hole 52 and pneumatic spring 3 31 upper end of shaft (rectangular pyramid shape) matches, and the shaft 31 of the pneumatic spring 3 is plugged in lower cone hole 52.
As shown in Fig. 2, the pneumatic spring 3 is equipped with shell 36, convex rotor 32 is equipped in shell 36;The convex rotor 32 top is fixed with shaft 31;The lower section of the convex rotor 32 is equipped with guide holder 37;The periphery of the guide holder 37 is equal Several guide grooves 38 are furnished with, 36 inner wall of the shell is equipped with and 38 matched gib block of guide groove;Shell 36 and guiding Slot 38 coordinates, make guide holder 37 can only vertical and straight movement, and cannot rotate.The bottom of the guide holder 37 is equipped with piston rod 35, institute It states one end that piston rod 35 is connect with guide holder 37 and is equipped with anti-wear cover.Support sealing shroud 33, the work are equipped in the shell 36 Stopper rod 35 passes through support sealing shroud 33, and to enhance sealing performance, sealing shroud is equipped between piston rod 35 and support sealing shroud 33 Circle.
The lower component includes proximate matter lower cover 2 and bearing 21, and the middle part of the proximate matter lower cover 2 is equipped with Open Side Down Groove, the bearing 21 is assemblied in the groove.
The base assemblies include L-shaped bottom plate 1 and the lower shaft 11 that is assemblied on the horizontal segment of bottom plate 1, institute The longitudinal sections for stating bottom plate 1 are equipped with, and the lower shaft 11 matches with the bearing 21 in proximate matter lower cover 2.
Stealthy door closer described in the utility model using pneumatic spring assembles in use, by the longitudinal sections of bottom plate 1 It is inserted into the inner cavity of the doorframe bottom ends side frame A3, and doorframe side frame A3 is fixed on by the cooperation of bolt and mounting hole 12 On bottom end, in this way, the horizontal segment of bottom plate 1 is touched with ground, play the role of carrying door body, door body will not have with ground Any contact;It is assembled together again by lower shaft 11 is corresponding with the bearing 21 in proximate matter lower cover 2, the top margin frame of door body oppresses the axis of cone 6 bottom end, when the bottom end of the axis of cone 6 is aligned with the upper taper hole 51 of connecting bushing 5, under the thrust of spring 71, the axis of cone 6 Lower end is plugged in taper hole 51, after the completion of whole assembly, don't fail to keep the axis of cone 6, shaft 31, lower shaft 11 axle center same On straight line.When dismantling door body, it is only necessary to have the strip hole 61 that (flat screwdriver) dials up the axis of cone 6 by hand, make the axis of cone 6 It is disconnected the upper taper hole 51 of axle sleeve 5, you can door body is disassembled, it is very convenient quick.
It opens the door or at closing time, active force is applied to door body with hand, since the axis of cone 6 is assemblied on doorframe upper beam A1, It is fixed, thus, connecting bushing 5, shaft 31 also remain stationary as;When door body rotates, shaft 31 is relative to proximate matter frame A2 is rotated, and the shell 36 of pneumatic spring 3 is fixed relative to door body proximate matter frame A2, so, after 31 stress of shaft, band Dynamic convex rotor 32 rotates relative to door body, and guide holder 37 moves up and down under the driving of convex rotor 32.
Since pneumatic spring 3 is assemblied in the inner cavity of the door body proximate matter tops frame A2, the weight of door body is no longer carried, is also just lost The gravity suppressing action of door body has been removed, it so, need not very great can open the door and close the door or even wind-force is slightly larger When, wind blows door body and can open the door or close the door.It is happened in order to avoid such, traditional, pneumatic spring is improved, It is specific as follows:The bottom end of the piston rod 35 is fixed with piston 34, divides in the airtight cavity above and below the piston 34 Other oiling;The outer circumference surface of the piston 34 is equipped in annular groove 34A, the annular groove 34A and is equipped with sealing ring 39;It is described Annular groove 34A is respectively equipped with upper oil hole 34B, lower oilhole 34C close to the position of internal groove side wall;On the annular groove 34A and piston 34 The cavity of side is connected to by upper oil hole 34B, and annular groove 34A is connected to the cavity of 34 lower section of piston by lower oilhole 34C.By Oiling respectively in airtight cavity above and below piston 34 increases guide holder 37 in convex rotor 32 using the resistance of oil The resistance moved up and down under driving, and then increase the resistance for opening the door and closing the door.It can be with by adjusting the pore size of upper oil hole 34B The size of required power, speed speed at closing time can be then adjusted by adjusting the aperture of lower oilhole 34C when adjustment is opened the door.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection domain within.
