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.

Fig. 1 is outline drawing of the present invention, show dragline type air damper of the present invention assembled after state.
The principal character of each constituent part is as follows:
As shown in Figure 3, cylindrical shell 6, its inside is provided with cavity, one end open, and one end closes; Cylindrical shell 6 outer wall upper and lower side is respectively provided with an installing hole 61, cylindrical shell 6 is fixed on the screw column 91 of gloves casing 9 by installing hole 61 and screw; The top of cylindrical shell 6 is provided with cylindrical shell hole clipping 62, is positioned at two side walls, connects cover 2 for the grab 22 be provided with by cover.
As shown in Fig. 5, Fig. 6, Fig. 7, piston 4 is provided with hook hole 41, for installing stay cord 1; The centre of piston 4 is provided with air vent 43, and the two ends of air vent 43 are lateral surface 44 and medial surface 45, and the lateral surface 44 of piston 4 is provided with the air intake duct 46 of same air vent 43 connection, and the medial surface 45 of piston 4 is provided with the air discharge duct 47 of same air vent 43 connection; Piston 4 is provided with spring base 42, and back-moving spring 3 is installed on the spring base 42 of piston 4.
As shown in Figure 8, I-shaped valve 7, be made up of elastomeric material, its shaft 73 has the inner face 71 of umbrella shape and the outer face 72 of umbrella shape, I-shaped valve 7 through piston 4 air vent 43 by interior outer face 71 and 72 can be up and down be connected in piston 4 air vent 43, the end face outside 72 of I-shaped valve 7 is covered on air intake duct 46, and the inner side end 71 of I-shaped valve 7 is covered on air discharge duct 47, is provided with gap between the shaft 73 of the I-shaped valve air vent 43 with piston 4.
The mode that dragline type damper is assemblied in glove box is as follows:
As shown in Figure 9, Figure 10, dragline type air damper is screwed on the screw column 91 of gloves casing 9 by the installing hole 61 of cylindrical shell 6, and the line cover 11 of stay cord 1 one end hangs on the hook 81 of glove box lid 8.
The dragline type damper course of work is as follows:
Usual glove box is in the closed condition of Fig. 9.When opening glove box lid 8, as shown in figure 11, case lid 8 is rotated down around axis hole 82 and produces tensile force f 1 under dead-load moment effect, tensile force f 1 pulls piston 4 to rise by stay cord 1, back-moving spring 3 is compressed, piston 4 rises and makes cylindrical shell 6 inner chamber generation negative pressure F2(F2 be less than F1), under suction function, I-shaped valve 7 is adsorbed to be moved to the inside, end face outside 72 fits in the lateral surface 44 of piston 4 and forms air inlet tunnel on the part being covered in air intake duct 46, air enters the inner chamber of cylindrical shell 6 by the gap between the shaft 73 of air inlet tunnel and I-shaped valve 7 and the air vent 43 of piston 4, dragline type air damper enters air-suction state, along with piston speed increase time, because air inlet tunnel is very little, air inlet be not enough to fill piston 4 rise produce space, in chamber, vacuum increases, and negative pressure F2 increases, until the F2 increased identical with F1 with the elastic force sum of back-moving spring 3 after, stay cord speed becomes at the uniform velocity, and glove box lid 8 uniform rotation is opened.When closing glove box lid 8, as shown in figure 12, under the thrust of back-moving spring 3, piston 4 moves down and makes cylindrical shell 6 inner chamber produce malleation, at positive pressure, I-shaped valve 7 is pushed and moves laterally, thus end face outside 72 is with the lateral surface 44 separation formation exhaust clearance of piston 4, air is vented by the air discharge duct 47 of piston 4 and the gap between the shaft 73 of I-shaped valve 7 and the air vent 43 of piston 4, and dragline type air damper enters exhaust condition.
According to the load of glove box, the air intake duct of different size can be set, the air intake duct of reduced size can be set when load is larger, when load is less, larger air intake duct can be set.
As another embodiment of the present invention, air inlet can be offered to replace the air intake duct on piston at cylinder body bottom, same damping function can be realized.
