Abstract
The invention discloses a stay rope type air damper, comprising a cylindrical body, a cylinder cover, a stay rope, a return spring, a piston, an O-shaped ring, and an H-shaped valve. The cylindrical body is provided with an inner cavity. The inner cavity is provided with the piston. The piston is provided with the return spring. The cylinder cover is connected with the upper end of the cylindrical body. The stay rope passes through the return spring and the cylinder cover and is connected with the piston. At least an end of the stay rope is out of the cylindrical body. The O-shaped ring is arranged on the circular groove on the periphery of the piston, so that the piston and the inner wall surface of the cylindrical body form seal. The H-shaped valve is respectively provided with umbrella-shape end faces on two sides of the inner side and outer side of the piston. The H-shaped valve passes through a venthole and is clamped with the venthole of the piston in an up-down moving manner through the inner umbrella-shape end face and the outer umbrella-shape end face. On the basis of reducing components, simplifying structure, and reducing cost, the stay rope type air damper reduces exhaust noise and improves damping capacity.

Specific embodiment：
With reference to Fig. 1～Figure 12, the embodiment of dragline type air damper of the present invention described further below, but the present embodiment
It is not limited to the present invention, the analog structure of every employing present invention and its similar change, the protection of the present invention all should be listed in
Scope.
Dragline type air damper, it includes：Drawstring 1, cover 2, back-moving spring 3, piston 4, O-ring 5, cylinder 6, I-shaped
Valve 7；Drawstring 1 two ends are provided with line set 11；Drawstring 1 one end is installed on the hook hole 41 of piston 4, drawstring 1 other end by line set 11
Stretch out the outer hook 81 being linked into glove box lid 8 by line set 11 of cylinder 6；Cover 2, there is through hole 21 centre, is through drawstring 1 and installs
In cylinder 6 upper end；Back-moving spring 3, is through drawstring 1 and is installed on the spring base 42 of piston 4；Piston 4, is installed in cylinder 6
Chamber, can move back and forth in cylinder 6；O-ring 5, is installed in the annular groove 48 of piston 4, in cylinder 6 internal face with piston 4 periphery
Between seal；Cylinder 6, inside is provided with cavity, accommodates each constituting parts；I-shaped valve 7, through piston 4 passage 43 pass through inside and outside
Umbrella shape end face 71 and 72 can be connected in passage 43 up and downly.
Fig. 1 is the outline drawing of the present invention, shows the state after the completion of dragline type air damper assembling of the present invention.
The principal character of each constituent part is as follows：
As shown in figure 3, cylinder 6, it is internally provided with cavity, one end open, one end closes；Cylinder 6 outer wall upper and lower side respectively sets
An installing hole 61, cylinder 6 is had to be fixed on the screw column 91 of glove casing 9 by installing hole 61 and screw；The top of cylinder 6
It is provided with cylinder hole clipping 62, positioned at two side walls, the grab 22 for being provided with by cover connects cover 2.
As shown in Fig. 5, Fig. 6, Fig. 7, piston 4 is provided with hook hole 41, for installing drawstring 1；The centre of piston 4 is provided with ventilation
Hole 43, the two ends of passage 43 are lateral surface 44 and medial surface 45, and the lateral surface 44 of piston 4 is provided with what same passage 43 connected
Air inlet duct 46, the medial surface 45 of piston 4 is provided with the air discharge duct 47 that same passage 43 connects；Piston 4 is provided with spring base 42, multiple
Position spring 3 is installed on the spring base 42 of piston 4.
As shown in figure 8, I-shaped valve 7, it is made up of elastomeric material, its shaft 73 has the inner face 71 of umbrella shape and the outer of umbrella shape
End face 72, I-shaped valve 7 passes through the passage 43 of piston 4 can be connected in piston 4 by interior outer face 71 and 72 up and downly
Passage 43, the end face outside 72 of I-shaped valve 7 is covered on air inlet duct 46, and the inner side end 71 of I-shaped valve 7 is covered in aerofluxuss
On groove 47, the shaft 73 of I-shaped valve is provided with gap between the passage 43 of piston 4.
The mode that dragline type antivibrator is assemblied in glove box is as follows：
As shown in Figure 9, Figure 10, dragline type air damper is screwed in glove box by the installing hole 61 of cylinder 6
On the screw column 91 of body 9, the line set 11 of drawstring 1 one end hangs on the hook 81 of glove box lid 8.
Dragline type antivibrator work process is as follows：
Generally glove box is in the closed mode of Fig. 9.When opening glove box lid 8, as shown in figure 11, case lid 8 is in deadweight
It is rotated down generation pulling force F1 around axis hole 82, pulling force F1 pulls piston 4 to rise by drawstring 1, back-moving spring 3 quilt under moment loading
Compression, piston 4 rises makes cylinder 6 inner chamber produce negative pressure F2 (F2 is less than F1), and under suction function, I-shaped valve 7 is inwardly adsorbed
Side shifting, end face outside 72 fits in the lateral surface 44 of piston 4 and is covered in formation air inlet tunnel on a part for air inlet duct 46
Road, the gap that air passes through between the shaft 73 of air inlet tunnel and I-shaped valve 7 and the passage 43 of piston 4 enters the interior of cylinder 6
Chamber, dragline type air damper enters air-suction state；When increasing with piston speed, due to air inlet tunnel very little, enter QI-insufficiency
With fill piston 4 rise produce space, intracavity vacuum increase, negative pressure F2 increase, until increase F2 with back-moving spring 3 bullet
After power sum is identical with F1, drawstring speed is changed at the uniform velocity, and glove box lid 8 uniform rotation is opened.When closing glove box lid 8, such as
Shown in Figure 12, under the thrust of back-moving spring 3, piston 4 moves down makes cylinder 6 inner chamber produce malleation, in positive pressure
Under, I-shaped valve 7 is promoted outside side shifting, thus end face outside 72 separates with the lateral surface 44 of piston 4 forms exhaust clearance, empty
Gas passes through the gap aerofluxuss between the air discharge duct 47 of piston 4 and the shaft 73 of I-shaped valve 7 and the passage 43 of piston 4, dragline type
Air damper enters exhaust condition.
According to the load of glove box, different size of air inlet duct can be set, load can arrange reduced size when larger
Air inlet duct, load less when larger air inlet duct can be set.
As another embodiment of the present invention, air inlet can be opened up to replace the air inlet duct on piston in cylinder body bottom,
Can achieve same damping function.
