Utility model content
The purpose of this utility model is just to provide one to solve the problem, under the equipment that can use in a liquid, facility need external cord body (pipe, line body) to adopt the condition of sealing means, make full use of mode that compact heap coordinates with rubber ring and form the sealed wiring device effectively carrying out anti-high pressure under liquid.
To achieve these goals, the technical solution adopted in the utility model is: the sealed wiring device of anti-high pressure under a kind of liquid, comprise Binding post/stud and nut, described Binding post/stud and nut offer winding displacement hole, described Binding post/stud is fixed on workpiece, described Binding post/stud front end surface offers the hole slot that cross section is U-shaped, compact heap is provided with in hole slot, the front end of described compact heap is positioned at the circular arc position bottom hole slot, the inner top surface of nut is close in the rear end of compact heap, the front end surface of described compact heap concaves formation arc surface, O-ring seals is provided with between the front end surface of described compact heap and the bottom surface of hole slot, the middle part of described compact heap offers the through hole corresponding with winding displacement hole along its length.
As preferably, described Binding post/stud front end is connected with its thread by stroke screw thread, and described Binding post/stud end is provided with binding thread, is threaded with workpiece by binding thread.
As preferably, described Binding post/stud is provided with base away from nut one end, described base and Binding post/stud one-body molded, be provided with sealing ring between described base and workpiece madial wall.
As preferably, described winding displacement hole, hole slot, through hole are positioned on same axis, and line body to be installed passes from nut through after Binding post/stud, O-ring seals, compact heap, briquetting successively.
As preferably, between described nut and compact heap, be also provided with the briquetting reducing relative friction forces, described briquetting offer the winding displacement hole corresponding with nut.
As preferably, described O-ring seals can be flexible graphite sealing ring or flexible asbestos seal ring.
Compared with prior art, the utility model has the advantage of: the utility model makes full use of the mode that compact heap coordinates with rubber ring, when liquid depth≤3500 meter, effectively prevent the situation that liquid leaks at line outlet, use is more reliable, practical and sealing property is better, and electric wire body does not need strip off to decompose wiring, avoided welding position and liquid comes into contact.Can be used for sealing the equipment, the facility electric wire body leading-out terminal that use in a liquid.Also can be used for the pipe fitting in on-liquid environment or the sealing of line body.
