The utility model content
The purpose of the utility model is the deficiency to prior art, provide a kind of simple in structure, cost of manufacture is low, good and Vehicular door long service life of shock-proof effect is used the aeroelasticity automatic switch.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
The described a kind of Vehicular door of the utility model is used the aeroelasticity automatic switch; It comprises cylinder body; An end is provided with rotating shaft seal circle and spacer successively in the said cylinder body; Piston rod one end passes the rotating shaft seal circle and is fixedly connected with the spacer piston interior with being located at cylinder body, and the piston rod other end stretches out outside the cylinder body; Be connected with stage clip between said piston and the cylinder body other end bottom; Form cavity between said piston and the spacer, cylinder body is provided with gas port, and said gas port is communicated with cavity.
Further, be provided with plain washer between said rotating shaft seal circle and the cylinder body end face.
Further, said cavity is provided with cushion pad.
Further, said piston rod passes piston one end end and nut is spirally connected fixing.
Further, pad is provided with plain washer and spring washer between said nut and the piston.
Further, be provided with plain washer between said stage clip and the cylinder base.
Further, said outer wall of cylinder block one side is provided with fixed head.
After adopting said structure, the utility model beneficial effect is: the utility model drives piston and piston rod and moves right through to the gas port inflation; After losing heart through gas port; Under the effect of stage clip, piston and piston rod are moved to the left, thereby effectively realize the keying of car door.The utility model is simple in structure, and cost of manufacture is low, and is easy to use.
Description of drawings
Fig. 1 is the utility model sectional structure sketch map.
Among the figure:
1, piston rod; 3, plain washer; 4, rotating shaft seal circle; 5, spacer; 7, cushion pad; 9, piston; 11, spring washer; 12, nut; 13, fixed head; 14, cylinder body; 15, stage clip; 17, gas port; 18, cavity.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1; The described a kind of Vehicular door of the utility model is used the aeroelasticity automatic switch; It comprises cylinder body 14, stage clip 15, piston 9 and piston rod 1, and above-mentioned several parts constitute the utility model agent structure, and cylinder body 14, stage clip 15 and piston rod 1 all adopt metal material to process and form; The piston 9 general plastic materials that adopt are processed.
Aforementioned body modular construction annexation is following:
An end is provided with rotating shaft seal circle 4 and spacer 5 successively in the said cylinder body 14, and particularly, said rotating shaft seal circle 4 is located at spacer 5 outer ends; Be provided with plain washer 3 between said rotating shaft seal circle 4 and cylinder body 14 end faces, mainly play cushioning effect.
Pistons 9 in said piston rod 1 one ends pass rotating shaft seal circle 4 and spacer 5 and are located at cylinder body 14 are fixedly connected; Particularly; Piston rod 1 one ends pass piston 9 and nut 12 and are spirally connected fixingly, and pad is provided with plain washer 3 and spring washer 11 between said nut 12 and the piston 9, a cushioning effect.Certainly, the utility model also can adopt other form to be fixedly connected.Piston rod 1 other end stretches out outside the cylinder body 14 and is connected with car door.
Be connected with stage clip 15 between said piston 9 and cylinder body 14 other ends bottom, be provided with plain washer 3 between said stage clip 15 and cylinder body 14 bottoms.
Form cavity 18 between said piston 9 and the spacer 5, cylinder body 14 is provided with gas port 17, and said gas port 17 is communicated with cavity 18.Said gas port 17 connects extraneous source of the gas, and when source of the gas during to gas port 17 inflations, cavity 18 internal pressure superchargings promote piston 9 and piston rod 1 and move down, piston rod 1 pulling car door opening, and this moment, stage clip 15 was in compressive state; When gas port 17 lost heart, under the effect of stage clip 15, piston 9 and piston rod 1 moved up, and promoted closing of the door.
Be provided with cushion pad 7 in the said cavity 18, the extruding between main damper piston 9 and the spacer 5.
