the first blank holder 410, fairlead 230, nut member 240 all synchronously moves downward, the sidewall of flexible sealing component 300 produces strain, owing to having certain distance between the lug boss 231 on fairlead 230 and slip ring 250, when operator continues to press button cap 210 downwards, lug boss 231 on fairlead 230 will be encountered slip ring 250 and promote slip ring 250 and move downward, flexible sealing component 300 is by further strain, when slip ring 250 moves downward by elasticity of compression reset components 500, due to reaction force of the compressed generation of elastic reset member 500, the dynamics that makes operator can feel to continue to press button cap 210 downwards obviously strengthens, can remind operator to be confirmed whether to continue to press button cap 210 downwards, by such design, can avoid to a great extent by mistake the touch the button misoperation of cap 210 of operator, design very hommization.When operator unclamps button, under the reset response of elastic reset member 500 and flexible sealing component 300, button cap 210, push rod 220, the first lip limit 301, the first blank holder 410, fairlead 230, nut member 240 all synchronously move upward and restPose.Slip ring 250 adopts metal material manufacture, fairlead 230 adopts plastic material manufacture, by elastic reset member 500 is supported and is terminated on slip ring 250, with elastic reset member 500 supported to the mode terminating on fairlead 230 compare, under long-term use, can avoid the friction between fairlead 230 and elastic reset member 500 and make fairlead 230 damages, improve reliability of structure.
Particularly, as depicted in figs. 1 and 2, described cover member 110 outsides offer an annular groove 112, in described annular groove 112, be provided with elastic sealing ring 170, elastic sealing ring 170 adopts elastomeric material manufactures, so that while jacket assembly 100 being installed on the shell of product, elastic sealing ring 170 plays the sealing function of a radial seal, prevent that rainwater from infiltrating interiors of products from the gap between jacket assembly 100 and the shell of product, improved the water resistance of product.
Preferably, described flexible sealing component 300 adopts silastic material manufacture, its good springiness and the anti-tear excellent performance that draws, and long-term use can be not damaged yet, improved the reliability of product.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
