Abstract
The utility model provides a titanium alloy clamp bolt, by the top cap, screw rod and the connecting block that sets up between top cap and screw rod are constituteed, the top cap is discoid, the top cap below is equipped with the connecting block, the connecting block is the cake form, the connecting block diameter is 25 of top cap diameter, the connecting block side evenly is equipped with the latch, latch quantity is 18~26, the latch is for dispersing the form, the latch is evenly dispersed to top cap one end by connecting block one end, all latch outer lane lines form a round platform, the great one side of this round platform floor space is the same with the top cap floor space, the below connecting screw rod of connecting block, wherein, it is little that the diameter of top cap, connecting block, screw rod is the coefficient demultiplication in proper order, and the coefficient is 0.8, and the screw rod diameter is 0.8 times of connecting block diameter promptly, and the connecting block diameter is 0.8 times of the top cap diameter, the screw rod side evenly is equipped with the external screw thread, external screw thread from anticlockwise even the encircleing to the screw rod bottom in screw rod top, and the external screw thread width is 0.05~0.1 times of the screw rod diameter, and the screw rod bottom is equipped with the chamfer, and the chamfer is 15~30, and the bolt of being convenient for inserts.
Description
Technical field:
This use is novel relates to a kind of bolt, particularly relates to a kind of titanium alloy hold-down bolt.
Background technology:
Bolt is a kind of in order to fixing working standard part, has a wide range of applications in parts are fixing with the connection of parts.In existing bolt, when bolt be connected with equipment again through nut supporting fixing time, bolt very easily occurs to loosen or connect there is leakage point, not only easily causes the fault of equipment, and there is great potential safety hazard, brings inconvenience to user.
Utility model content:
For the deficiency of above-mentioned technology, this utility model devises a kind of titanium alloy hold-down bolt, is made up of top cover, screw rod and the contiguous block that is arranged between top cover and screw rod.
It is discoid that this utility model solves the technical scheme is that top cover of its technical problem, top cover is connected with contiguous block, contiguous block is round pie, contiguous block diameter is the 2/5 of cap diameter, and contiguous block side is uniformly provided with latch, and latch quantity is 18～26, latch is divergent shape, latch is uniformly dispersed to top cover one end by contiguous block one end, and all latch outer rings line forms a round platform, and this round platform bigger side floor space is identical with top cover floor space；Contiguous block be connected below screw rod, wherein, top cover, contiguous block, screw rod diameter reduce again in coefficient successively, coefficient is 0.8, and namely screw diameter is 0.8 times of contiguous block diameter, and contiguous block diameter is 0.8 times of cap diameter；Screw rod side is uniformly provided with external screw thread, and external screw thread is from screw tip uniform ring counterclockwise around to screw rod, and external screw thread width is 0.05～0.1 times of screw diameter, is provided with chamfering bottom screw rod, and chamfering is 15 °～30 °, it is simple to bolt inserts.
The beneficial effects of the utility model: stable connection, firmly.
Accompanying drawing illustrates:
Fig. 1 is main TV structure figure of the present utility model；
Wherein, 1-top cover, 2-screw rod, 3-contiguous block.
Detailed description of the invention:
This utility model devises a kind of titanium alloy hold-down bolt, it is made up of top cover, screw rod and the contiguous block that is arranged between top cover and screw rod, top cover is discoid, top cover is connected with contiguous block, contiguous block is round pie, contiguous block diameter is the 2/5 of cap diameter, contiguous block side is uniformly provided with latch, latch quantity is 18～26, latch is divergent shape, latch is uniformly dispersed to top cover one end by contiguous block one end, and all latch outer rings line forms a round platform, and this round platform bigger side floor space is identical with top cover floor space；Contiguous block be connected below screw rod, wherein, top cover, contiguous block, screw rod diameter reduce again in coefficient successively, coefficient is 0.8, and namely screw diameter is 0.8 times of contiguous block diameter, and contiguous block diameter is 0.8 times of cap diameter；Screw rod side is uniformly provided with external screw thread, and external screw thread is from screw tip uniform ring counterclockwise around to screw rod, and external screw thread width is 0.05～0.1 times of screw diameter, is provided with chamfering bottom screw rod, and chamfering is 15 °～30 °, it is simple to bolt inserts.
This utility model reaches the compression effect of screw rod by arranging contiguous block between top cover and screw rod, it is ensured that stable connection, firmly.Contiguous block side is provided with the latch of 18～26 divergent shapes, more deep along with screw rod, and the compression effect of latch also becomes apparent from, very easy to use.
