Description
Technical field
The utility model relates to a kind of spring fastening bolt.
Background technique
Current bolt specification is on the market varied, but general configuration is similar, the occasion just used is different, after long-time use, bolt head long term exposure outside, is easy to cause surface oxidisation to be worn and torn, thus cannot dismantles, and common bolt inside cannot be fastening, cause easily getting loose in particular circumstances.
Model utility content
The technical problems to be solved in the utility model is: for solving above-mentioned Problems existing, provide a kind of spring fastening bolt, solve plain bolt top get rusty easily wearing and tearing and bottom cannot fastening anti-loose problem.
The utility model solves the technological scheme that its technical problem adopts: a kind of spring fastening bolt, the screw rod comprising bolt head and be fixedly connected with bolt head bottom, inside screw is provided with through hole, through hole inner diameter diminishes from top to bottom gradually, through hole lower ending opening position is provided with two gap, gap from top to bottom width broadens gradually, the nearly lower ending opening position of through hole madial wall is fixedly connected with baffle plate, the saddle bar for supportting large gap is provided with in through hole, the high-strength spring for supporting saddle bar is provided with between baffle plate upper surface and saddle bar lower surface, bolt head offers blind round hole, blind hole bottom surface and cross screw bolt criticize corresponding groove, groove inner bottom surface offers the opening corresponding with through hole, bolt head upper hinge is connected with lid, the corresponding blind hole position of lid lower surface is fixedly connected with projection, convex lower surface central position is fixedly connected with for the push rod corresponding with saddle bar, lid is fixedly connected with bolt head by protruding blind hole of inserting.
Further, in order to prevent saddle bar cannot resilience, saddle bar outer surface be provided with lubricating layer.
Further, in order to increase antirust area, lid outer diameter is identical with bolt head outer diameter length.
Further, in order to promote antirust ability, projection diameter is identical with blind hole inner diameter length.
The beneficial effects of the utility model are, spring fastening bolt of the present utility model protects bolt top by top cover, prevent from getting rusty, and support the diameter bottom king-bolt, not only extend the working life of bolt, and prevent bolt from getting loose.
