Abstract
The utility model aims at resolving the problem that an existing stud is not easy to disassemble in replacement, and discloses a stud convenient to disassemble. The stud comprises a middle threaded rod and heads at two ends of the threaded rod, threads are formed on the heads, the threaded rod is arranged to be a regular hexagon column body, and distances between opposite vertexes of the regular hexagon column body are equal to the diameter of the threaded rod. When studs assembled on a machine base and a machine shell are damaged or need disassembling, a spanner is used for clamping a regular hexagon in the middle of the threaded rod, the spanner is rotated to disassemble the studs, and special tools are not needed to be used.
Description
Technical field
The utility model relates to a kind of bolt, specifically is a kind of easy-to-dismount stud bolt.
Background technique
Stud bolt is stud, and stud bolt is that there is screw thread at a kind of two ends and the centre is the double-screw bolt of polished rod.This bolt is used in the intensity height, the occasion that fastening space is little, and as component such as casing, supports, perhaps connecting body thickness is very big, when needing bolt length very long, also can use stud bolt.Tapped hole is arranged on the body, stud is screwed into earlier in the tapped hole, put other coupling nut screwing clamping again.Because annex is often dismounting, screw thread can wear and tear or damage, and need change stud bolt.The stud bolt model of enumerating on the car gage spare handbook has models such as Q120, Q121, Q123, Q124, Q125, Q128, Q129.But it is cylindric that the middle polished rod of all standard dual head bolts partly is, and can't clamp during replacing, is difficult for demolition.
Summary of the invention
The purpose of this utility model is to solve existing stud bolt not easily detachable defective when changing, and a kind of easy-to-dismount stud bolt is provided.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of easy-to-dismount stud bolt, the screw rod in the middle of comprising and the head at screw rod two ends, head has screw thread, and screw rod is arranged to the regular hexagon cylinder, and the distance on the relative summit of regular hexagon cylinder equals the diameter of screw rod.When the stud bolt on being assemblied in support, casing damages or need dismantle, block the regular hexagon at screw rod middle part with spanner, rotating spanner unloads double threaded screw.
When stud bolt described in the utility model fracture, draw button, when needing to change, can dismantle easily and need not special tool.
Description of drawings
Fig. 1 is the structural representation of the utility model stud bolt.
Fig. 2 is cross section, screw rod middle part.
Among the figure, 1-screw rod, 2-head.
Embodiment
Below in conjunction with accompanying drawing the claimed technological scheme of the utility model is done and to be specified.
As shown in Figure 1, a kind of easy-to-dismount stud bolt described in the utility model, the screw rod 1 in the middle of comprising and the head 2 at screw rod 1 two ends, head has screw thread, screw rod 1 is arranged to the regular hexagon cylinder, and the distance on the relative summit of regular hexagon cylinder equals the diameter of screw rod 1.
During manufacturing, the mode of employing extruding is squeezed into the regular hexagon cylinder with the screw rod 1 of bolt, as shown in Figure 2, make in the cylinder of screw rod 1 part of the largest contours line on its e limit and stud bolt and connect, so just can not influence the passing property of stud bolt, hexagonal opposite side S can use the dismounting of standard openings spanner close to gage length.
It is for the ease of using spanner that screw rod 1 is arranged to non-cylinder, overcome the slip of spanner when blocking cylindrical body, therefore, also screw rod 1 can be arranged to quadrilateral cylinder, octagonal cylinder, or be to leave the plane conduct of even number symmetry and the surface of contact of spanner at screw rod 1 middle part surface.
Protection domain of the present utility model is not limited to above mode of execution; for those skilled in the art; the application can various deformation and change, all in the application spirit and principle within do any modification, improve and be equal to replacement and all should be included within the utility model protection domain.
