Abstract
The utility model discloses an outer hexagon bolt, including screw rod portion, hexagon head in the top of screw rod portion is connected, its characterized in that: the outside of interior hexagonal head is equipped with non-metallic's outer hexagonal head, and outer hexagonal head has the hexagonal heavy vestibule that matches interior hexagonal head, and the backing ring of the first body structure of outer hexagonal head is connected to the bottom of outer hexagonal head, and the backing ring fills up the bottom terminal surface of interior hexagonal head. The utility model discloses from the backing ring that can carry out spot welding with non-metal material fastening terminal surface in the area, the size that increases the hexagon head simultaneously is in order to make things convenient for pulling the operation to the bolt to have the locking function of stopping concurrently.
Description
Technical Field
The utility model relates to a fastener product, concretely relates to outer hexagon bolt.
Background
For some connectors with fastening end faces made of nonmetal materials, the metal bolts obviously cannot be used for spot welding connection operation on the fastening end faces, the bolts made of the nonmetal materials need to be specially processed, the maximum defect of the bolts made of the nonmetal materials is that the strength is not enough, and some materials are not easy to process. In addition, if not carry out spot welding and connect, for preventing to connect the back not hard up, generally set up retaining ring or split pin and be used for the stopping of bolt at the screw rod portion rod end of outer hex bolts at present, the assembly is inconvenient, and the structure can be comparatively complicated, though play the effect of connecting the stopping moreover, hardly play the effect of connecting locking.
Disclosure of Invention
The utility model aims at providing a not enough to prior art, the utility model aims at providing a from area can carry out the backing ring of spot welding with non-metal material fastening terminal surface, increase the size of hexagon head simultaneously and pull the operation with the convenience to the bolt to have the outer hexagon bolt of stopping locking function concurrently.
The utility model discloses a through following technical scheme implementation:
outer hexagon bolt, including screw rod portion, hexagon head in the top connection of screw rod portion, its characterized in that: the outside of interior hexagonal head is equipped with non-metallic's outer hexagonal head, and outer hexagonal head has the hexagonal heavy vestibule that matches interior hexagonal head, and the backing ring of the first body structure of outer hexagonal head is connected to the bottom of outer hexagonal head, and the backing ring fills up the bottom terminal surface of interior hexagonal head.
The outer hexagonal head is made of plastic.
The lower terminal surface of screw rod portion is equipped with the shrinkage pool, and the shrinkage pool makes the lower extreme tip of screw rod portion form thin-walled cylinder structure, and the section of thick bamboo wall of thin-walled cylinder is equipped with the incision of a plurality of axial directions, forms the bar body between the adjacent incision.
According to the outer hexagon bolt of the technical scheme, although the backing ring made of the non-metal material is only integrated with the outer hexagon head, the outer hexagon head is tightly matched with the inner hexagon head, so that after the backing ring made of the non-metal material and the connecting piece fastening end face made of the non-metal material are connected in a spot welding mode, the whole outer hexagon bolt is equivalently fixed in a spot welding mode. If the screw rod end of the outer hexagon bolt is not fixed by spot welding, when the screw rod end of the outer hexagon bolt is exposed out of the connector, the strip-shaped body at the screw rod end can be turned outwards to play a role in tightly riveting the connector and a role in stopping and preventing looseness, and the structure is simple.
Drawings
The utility model discloses there is following figure:
figure 1 is a schematic structural diagram of the present invention,
figure 2 is a top view in elevation of figure 1,
fig. 3 is a bottom view of fig. 1.
Detailed Description
As shown in the figure, the utility model discloses an outer hexagon bolt, including screw part 6, hexagon head 2 in screw part 6's top is connected, screw part 6 and interior hexagon head 2 are the metal material, interior hexagon head 2's the outside is equipped with non-metal material's outer hexagon head 4, outer hexagon head 4 has the hexagonal heavy vestibule 1 that matches interior hexagon head 2, the chamber wall of hexagonal heavy vestibule 1 is equipped with little arch 3 and prevents deviating from spacing to interior hexagon head 2, the backing ring 5 of the integrative structure of outer hexagon head 4 is connected and outer hexagon head, the bottom terminal surface of hexagon head 2 including backing ring 5 pads, outer hexagon head 4 and backing ring 5 are the plastics material. The lower end face of the screw rod part 6 is provided with a concave hole 7, the concave hole 7 enables the lower end part of the screw rod part 6 to form a thin-wall cylinder structure, the cylinder wall of the thin-wall cylinder is provided with a plurality of notches 8 in the axial direction, and strip-shaped bodies 9 are formed between every two adjacent notches 8.
Claims (3)
