Nut device with lead sealing function

Abstract

A nut device with a lead-sealing function is suitable for mounting on a base for screwing a screw. The nut device includes a nut, a wire, a spacer cap, and a lead seal. The nut is screwed onto the screw and includes a through-hole. The wire passes through the through-hole and includes two oppositely positioned ends. The spacer cap and the base define an isolation space communicating with the through-hole. The spacer cap covers the screw and includes a through-hole communicating with the outside of the isolation space. The ends protrude through the through-hole and are exposed outside the spacer cap. The lead seal seals the ends. By sealing the wire with the lead seal after it passes through the nut and is then sealed outside the spacer cap, unauthorized operation of the nut without leaving a trace can be prevented, thus improving safety.

Claims

1. A nut device with a lead-sealing function, suitable for mounting on a body for screwing a screw, the nut device comprising: a nut for screwing onto the screw, the nut including a through-hole; a wire passing through the through-hole, the wire including two oppositely arranged ends and a middle portion connecting the ends; a partition cap disposed on the body, the partition cap cooperating with the body to define a space communicating with the through-hole, the partition cap covering the screw and including a through hole communicating with the outside of the partition space, the middle portion passing through the through-hole, the ends passing through the through hole and exposed outside the partition cap; and a lead seal located outside the partition cap and sealing the ends.

2. The nut device with lead-sealing function as described in claim 1, wherein, The through hole extends along an axis.

3. The nut device with lead-sealing function as described in claim 1, wherein the base includes an external connecting portion disposed on the surface, wherein, The isolation cover also includes an inner peripheral surface surrounding an axis and facing the nut, and an inner connecting portion formed on the inner peripheral surface, which is connected to the outer connecting portion by a tongue-and-groove fit.

4. The nut device with lead-sealing function as described in claim 3, wherein, The internal connection extends circumferentially along the base.

5. The nut device with lead-sealing function as described in claim 1, wherein, The projected dimension of the lead seal toward the through hole is larger than the diameter of the through hole.

6. The nut device with lead-sealing function as described in claim 2, wherein, The distance between the lead seal and the isolation cover along the axis is less than 10 mm.
