Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

Example 1

The utility model provides a protection device for high tension fuse, as shown in fig. 1-4, including casing 1, connecting block 3, apron 31, fixed plate 11 and compression spring 12, six perpendicular equipartitions place hole 2 in the casing 1, the space of placing 2 bottoms in the hole communicates with each other, place 2 inside lateral walls of hole and control relative equal rigid coupling compression spring 12 from top to bottom, the common rigid coupling fixed plate 11 of compression spring 12 end of the left and right sides, 1 top welding connecting block 3 of casing, 3 articulated apron 31 of connecting block, make apron 31 can overturn and open the closure, apron 31 marginal inside is equipped with the magnetic stripe, it is sealed to make apron 31 and 1 actuation of casing through the magnetic stripe, 1 outside bonding protective sheath 4 of casing, protective sheath 4 material is rubber, can play the cushioning effect to the impact force of external collision.
