Abstract
The utility model provides a titanium alloy spring bolt comprises top cap, garter -type spring and screw rod, the top cap be solid hexahedron, the bottom surface is equipped with the ring flange under the top cap, the ring flange is discoid, the bottom surface area of ring flange is greater than the bottom surface area of top cap, the central line of ring flange and the central line of top cap are on a level straight line, be equipped with the bump under the ring flange on the bottom surface, the bump be circular solder joint, the bottom surface is equipped with the garter -type spring under the ring flange, and the garter -type spring both ends are equipped with spring holder and lower spring holder respectively, go up the spring holder and tightly weld with the bump, and lower spring holder one side is tightly fixed with the garter -type spring, is equipped with the wave stripe on the lower spring holder another side, be equipped with the screw rod under the ring flange on the bottom surface, inside the screw rod passed the spring, the screw rod was cylindric, the central line of screw rod central line and ring flange point -blank, the screw rod is equipped with the screw all around respectively, the screw rod bottom is equipped with a lug, the lug for round platform form, the radius that the screw rod was being kept away from to the lug is slightly little, makes things convenient for in the screw rod embedding parts.
Description
Technical field:
This use is novel relates to a kind of bolt, particularly relates to a kind of titanium alloy spring bolt.
Background technique:
Bolt is a kind of very general connection standard part, all uses in daily life.In the using process of bolt, pressure is not had between bolt and parts, bolt is caused easily to occur to loosen with parts joint, the soundness of bolts and nuts is directly caused to obtain destruction, make bolts and nuts occur to loosen the phenomenon even come off, great inconvenience is caused to people.
Model utility content:
For the deficiency of above-mentioned technology, the utility model devises a kind of titanium alloy spring bolt, is made up of top cover, annular spring and screw rod.
The technical solution adopted for the present invention to solve the technical problems is: described top cover is solid hexahedron, top cover bottom surface is provided with flange plate, flange plate is discoid, the base area of flange plate is greater than the base area of top cover, and the center line of flange plate and the center line of top cover are on a horizontal linear; Flange plate bottom surface is provided with salient point, and salient point number is four, and adjacent two salient points are apart from equal, and described salient point is circular solder joint; Flange plate bottom surface is provided with annular spring, annular spring two ends are respectively equipped with upper spring seat and lower spring cup, described upper spring seat and lower spring cup are as circular metal plate, upper spring seat tightly welds with salient point, lower spring cup one side is tightly fixing with annular spring, and lower spring cup another side is provided with wave stripe; Flange plate bottom surface is provided with screw rod, screw rod is through spring inner, screw rod is cylindric, the center line of pitch line and flange plate point-blank, screw rod surrounding is respectively equipped with screw thread, is provided with a projection bottom screw rod, and described projection is round table-like, projection is smaller at the radius surface away from screw rod, facilitates in screw rod built in items.
The beneficial effects of the utility model: convenient be connected with parts and be connected firmly, convenient disassembly.
Accompanying drawing illustrates:
Fig. 1 is main TV structure figure of the present utility model;
Wherein, 1-top cover, 2-annular spring, 3-screw rod.
Embodiment:
The utility model devises a kind of titanium alloy spring bolt, be made up of top cover 1, annular spring 2 and screw rod 3, described top cover 1 is solid hexahedron, top cover 1 bottom surface is provided with flange plate, flange plate is discoid, the base area of flange plate is greater than the base area of top cover, and the center line of flange plate and the center line of top cover, on a horizontal linear, guarantee flange plate and top cover uniform force; Flange plate bottom surface is provided with salient point, and salient point number is four, and adjacent two salient points are apart from equal, and described salient point is circular solder joint; Flange plate bottom surface is provided with annular spring 2, annular spring 2 two ends are respectively equipped with upper spring seat and lower spring cup, described upper spring seat and lower spring cup are as circular metal plate, upper spring seat tightly welds with salient point, lower spring cup one side is tightly fixing with annular spring, and lower spring cup another side is provided with wave stripe; Flange plate bottom surface is provided with screw rod 3, and screw rod is through spring inner, and screw rod 3 is cylindric, and point-blank, screw rod 3 surrounding is respectively equipped with screw thread to the center line of pitch line and flange plate, increases the friction between screw rod 3 and parts; Be provided with a projection bottom screw rod 3, described projection is round table-like, and projection is smaller at the radius surface away from screw rod 3, facilitates in screw rod 3 built in items.
The utility model by arranging an annular spring on flange plate bottom surface, by upper spring seat, annular spring is fixed on flange plate, extrudes part to be fixed by lower spring cup, increase the active force between screw rod and part, prevent part from occurring to loosen, very easy to use.
