Embodiment
In order that of the present utility model realize that technological means, creation characteristic, reached purpose and effect are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
As shown in figures 1-4, a kind of plane formula waterproof captive screw, including：Pedestal 11, screw 12, the pedestal 11 are set
Put between a target part 21 and two target parts 22, the outside of pedestal 11 is provided with base nut 14, screw 12 is arranged in pedestal 11,
One end outer sheath that screw 12 is inserted into pedestal 11 is provided with spring 13, and the pedestal 11 includes screw head accommodating chamber 111, bullet
Spring accommodating chamber 112, screw end accommodating chamber 114, provided with pedestal between spring accommodating chamber 112 and screw end accommodating chamber 114
Screwed hole 113, the outside of pedestal 11 is provided with pedestal external screw thread 115, and base nut 14 is arranged on pedestal 11 by pedestal external screw thread 115
The groove 116 of sealing ring one is provided with the downside of outside, the upper end of pedestal 11, the upper end of nail head accommodating chamber 111 is provided with the groove 117 of sealing ring two, spiral shell
Follow closely the lower end of end accommodating chamber 114 and be provided with the groove 118 of sealing ring three.
Junction is provided with sealing ring 3 17 between the target part 22 of pedestal 11 and two, and sealing ring 3 17 is arranged on sealing ring
In three grooves 118.
Junction is provided with sealing ring 1 between the target part 21 of pedestal 11 and one, and sealing ring 1 is arranged on sealing ring
In one groove 116.
Junction is provided with sealing ring 2 16 between the screw 12 and pedestal 11, and sealing ring 2 16 is arranged on the groove of sealing ring two
In 117.
The head type of screw 12 can be hexagon socket head or crosshead or manifold or hexagonal flower-shape head, the middle part of screw
For cylindrical bar, cylinder shank diameter is smaller than screw external screw thread specification.
The spacing target part 21 of boss of the pedestal the top, height of the height compared with the screw head of same specification of boss
It is low, coordinate the screw head accommodating chamber 111 on pedestal top, screw head is completely embedded into cavity after fastening, in production after assembling
