Compared with prior art, the beneficial effects of the present invention are:
(1) the combined type hex bolts is by being provided with main thread bar and deputy thread bar, so that the length of the combined type hex bolts
Degree can be flexibly changed according to the actual situation.
(2) the combined type hex bolts is by being provided with boss and cross cavity, so that the combined type hex bolts is not having
It can use boss when having spanner and cross cavity replaced with hand or screwdriver, facilitate installation.
(3) the combined type hex bolts is by setting umbellate form nut, so that the combined type hex bolts is in outdoor from rain
Water erosion.
(4) the combined type hex bolts is by being provided with plain cushion, so that the combined type hex bolts avoids scraping during installation
Spend part to be installed.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1-3 is please referred to, a kind of embodiment provided by the invention: a kind of combined type anticorrosion bolt, including boss 1, umbrella
Type nut 3, spring washer 4, smooth surface screw rod 5, main thread bar 6, deputy thread bar 8, cruciform groove 9, screw thread 10, plain cushion 12 and threading hole
16, the underface of boss 1 is equipped with connector 2, and the shape of boss 1 is consistent with bolt head 14, is regular hexagon, and boss
1 upper surface offers cross bore, so that cross cavity 15 is not blocked, and the underface of connector 2 is connected with bolt head 14, umbrella
Connector 2 is fixedly connected at the upside port of type nut 3, umbellate form nut 3 and the surface of plain cushion 12 are enclosed with one layer of gum cover,
And the gum cover is made of silicone gum rubber material, so that umbellate form nut 3 is protected, is prolonged the service life, the centre of elastic slice 4 is worn
It is inserted with newel 13, newel 13 and the junction of bolt head 14 are provided with several anti-slop serrations, and the surface of newel 13 is attached
