Existing bolt head is mostly the hexagon or other shapes of direct-dismounted dual on the market, is easily disassembled, and what is used in the past is a variety of
The check bolt of form, but all different degrees of Shortcomings, easily produce loose phenomenon, do not possess anti-theft feature, make equipment
Increase maintenance rate, use the problem of cumbersome.
To achieve the above object, the utility model provides following technical scheme：A kind of anti-loose, anti-theft fastening bolt, including spiral shell
Bolt head, fixture, screw rod and firm layer, the surface of the bolt head is provided with bolt head groove, and bolt head rear surface is consolidated
Surely there is screw rod standing groove, the fixture is arranged on the inner hub location of screw rod standing groove, and fixture edge is provided with bullet
Property tabletting, the screw rod is fixed on the inner hub location of fixture, and screw rod lower end is provided with locking screw rod, the firm layer
Installed in the rear surface of locking screw rod.
Preferably, the bolt head groove is triangular structure, and its depth bounds is 3mm-5mm.
Preferably, the screw rod standing groove is arc-shaped structure.
Preferably, the fixture is cirque structure, and its upper surface and bolt head groove center surface soldered.
Preferably, the elastic pressuring plate is uniformly arranged in umbrella frame shape around screw rod, and elastic pressuring plate number is at least 4.
Preferably, the firm layer is anaerobism gel coating.
Compared with prior art, the beneficial effects of the utility model are：The anti-loose, anti-theft fastening bolt, in use, with it is general
Logical bolt needs to carry out locking difference by spring washer when in use, due to there is provided the elastic pressuring plate of annular arrangement, working as rotation
After tight bolt, the elastic pressuring plate being fixedly connected with bolt head is extruded generation elastic deformation, by elastic force caused by elastic pressuring plate
The elastic force of spring washer be instead of to prevent bolt looseness, product is used spring washer, effectively improve intensity,
Avoid loosening, locking screw rod lower end is provided with anaerobism gel coating, forms tough plasticity glued membrane with locking screw rod lower end after solidification, makes
Screw lock will not loosen, and be screwed as long as inserting screws into, you can reach expected anti-loosing effect, it is still removable after solidifying
Unload, the outer excessive glue of glue-line does not solidify in addition, is easy to remove, the bolt head groove that bolt head upper end is set, is exclusive triangle knot
Structure combines, and only special spanner can be opened, and other people have no way of doing it at all, and anti-detaching theft-proof effect is good, securely and reliably, cost
It is low, service life length.
