The specific embodiment
For being illustrated more clearly in content of the present invention, with embodiment the present invention is described in further detail with two joint hollow tubes below in conjunction with accompanying drawing.
As shown in Figure 1, flat push type automatically closing door and window device of the present invention comprises shell 2, extension spring 10 and push pedal 14.One end of shell 2 is totally enclosed blind ends 21, and the other end is the through hole end 22 that is provided with through hole 7.Shell 2 inside are provided with that some sizes are nested and hollow tube 6 slidably, hollow tube 6 comprises maximum hollow tube 61 and minimum hollow tube 62, hollow tube 6 one ends are fixed with hollow piston 3, the other end stretches out shell 2 becomes free end 63, except that minimum hollow tube 62, other hollow tube free ends 63 have through hole 7.Minimum hollow tube free end 63 outer walls and maximum hollow tube through hole 7 are slidingly matched; Maximum hollow tube free end 63 outer walls and outer casing through hole 7 are slidingly matched.Closed termination of outer cover 21 ends are equipped with dismountable spring base 1, and spring base 1 is tightly connected with blind end 21.Extension spring 10 is in shell 2 and minimum hollow tube 62, and the one end is fixed on the spring base 1, and the other end is fixed on the plug 11 that is positioned at minimum hollow tube free end 63.
As depicted in figs. 1 and 2, the periphery of minimum hollow piston 32 is provided with a ring-shaped groove 50, can supply ccontaining B sealing ring 42, the width of this ring-shaped groove 50 is slightly greater than the thickness of B sealing ring 42, make B sealing ring 42 under minimum hollow piston 32 drives, do to come and go when mobile, can contact one side sidewall of ring-shaped groove 50 respectively and break away from the another side sidewall.Bottom land at ring-shaped groove 50 is provided with some the straight shape grooves 52 that pass to ring-shaped groove 50 two sides vertically; Straight shape groove 52 quantity with bottom land are identical, width equates near being provided with on the sidewalls of closed termination of outer cover 21 at ring-shaped groove 50, the position relatively, arrange radially and the straight trough 51 of straight-through ring-shaped groove 50 outer rims along sidewall; At ring-shaped groove 50 near being provided with the tiny straight trough 53 that links to each other with wherein straight shape groove 52 of bottom land and lead to ring-shaped groove 50 outer rims on the sidewalls of outer casing through hole end 22.B sealing ring 42 is slidable sealing with the inwall of maximum hollow tube 61 and cooperates, and is with ring-shaped groove 50 bottoms of minimum hollow piston 32 to contact or the noncontact cooperation.
Maximum hollow piston 31 and the structure of A sealing ring 41 and the structural similarity of minimum hollow piston 32 and B sealing ring 42 are not repeated, and its difference is that A sealing ring 41 is slidable sealing with the inwall of shell 2 and cooperates.
As shown in figures 1 and 3, the plug 11 that is positioned on the free end 63 of minimum hollow tube 62 is the flat side's 111 of an end band a cylinder 113, and a circular hole 112 is arranged on the flat side 111, is used for fixing an end of extension spring 10.Cylinder 113 is sealed and matched with the endoporus face of cylinder of minimum hollow tube 62, the middle part of cylinder 113 is fixed with a straight pin 12 that radially passes cylinder 113 centers, the part that straight pin 12 two ends exceed cylinder 113 is stuck in two place's draw-in grooves 8 of minimum hollow tube 62 end radial symmetric, and feasible mobile and rotation by plug 11 can drive minimum hollow tube 62 and do corresponding mobile and rotation.The cylinder 113 that plug 11 stretches out minimum hollow tube 62 is provided with bearing pin 13, and bearing pin 13 radially passes cylinder 113 centers and the big end of an end is little, and the small end 131 of bearing pin 13 exceeds cylinder 113 some length.
As Fig. 1, Fig. 3 and shown in Figure 4, push pedal 14 is a S plate parts independently, and push pedal 14 1 ends have opening draw-in groove 141, and an other end has installing hole 142.
During actual the use, to be positioned at the side that installing plate 9 on the closed termination of outer cover 21 is fixed on the last slide rail of horizontal sliding door, window with screw, on the frame of the horizontal sliding door that opens and closes of control, window, the small end 131 of the bearing pin 13 on the plug 11 of minimum hollow tube 62 is stuck in the opening draw-in groove 141 of push pedal 14 by screw in push pedal 14.When horizontal sliding door, window move toward the direction away from shell 2, push pedal 14 is slided outward by the elastic force that the minimum hollow tube 62 of bearing pin 13 pullings overcomes extension spring 10, because the A sealing ring 41 on the maximum hollow piston 31 and the friction area of shell 2 inner cylinder faces cause the B sealing ring 42 of its resistance on the minimum hollow piston 32 and the frictional resistance of maximum hollow tube 61 inner cylinder faces greatly, when having only minimum hollow piston 32 on being positioned at minimum hollow tube 62 to reach the free end 63 of maximum hollow tube 61, maximum hollow tube 61 is setting in motions.The free end 63 of minimum hollow tube 62 can move to the through hole end 22 that maximum hollow piston 31 arrives shell 2 always, and the pulling force of extension spring 10 this moment reaches maximum value; After door and window lost pulling force, under the elastic force effect of extension spring 10, minimum hollow tube 62 and maximum hollow tube 61 were withdrawn in the shell 2 successively, and door and window is closed.Because being provided with relatively in the ring-shaped groove 50 of hollow piston 3, ring-shaped groove 50 produces the sealing ring 4 of axial displacement, when motion is stretched out in hollow tube 6 generations, the air in hollow piston 3 closed at both ends spaces can smooth and easyly communicate, and hollow piston 3 motions are not subjected to the effect of air resistance, and the strength of opening the door is less; When hollow tube 6 produced retraction movement, the air in hollow piston 3 closed at both ends spaces flowed and is subjected to resistance, and hollow piston 3 motions are subjected to air-damped cushioning effect, thus partial offset the return active force of extension spring 10, make door closing force soft.If do not wish automatically closing door and window, can make bearing pin 13 small ends 131 break away from the opening draw-in groove 141 of push pedal 14 by rotation plug 11, safety shutoff will quit work.
The foregoing description can not be thought limiting the scope of the invention, those skilled in the art's base
Change that technical scheme of the present invention or means are made or improvement as the structure that changes spring base, push pedal, the quantity of increase and decrease hollow tube etc., all should fall within the protection domain of claim of the present invention.
