Abstract
The utility model relates to a bolt with paired holes in one end. The bolt comprises a bolt rod and a bolt head which are connected together, wherein screw threads are distributed on a part or in the whole length of the bolt rod; and the paired holes are formed in the bolt head. The bolt is simple in structure and low in cost, is convenient and practical, and can eliminate potential safety hazards, such as fall injury and work injury caused by the factor that a person is tripped by a traditional bolt head.
Description
Technical field
The utility model relates to a kind of fastening piece and kit thereof, relates in particular to paired hole, termination bolt.
Background technique
Walking on the road limit, slowly in by equipment, take a broad view on lathe and all can see hexagon head bolt and square head bolt, they are the most frequently used fastening pieces that connected and fix, be widely used among industrial and agricultural production and people's life, especially thick hexagon head bolt is used for fixing various device, lamppost, electric tower in large quantities, and first-class for various big machineries.Its corner angle of the hexagon head of hexagon head bolt are clearly demarcated and sharp keen, and the thick hexagon head under road cowl lamp post makes the people trip sometimes, even by people's tumble injury; The thick hexagon head that the indoor and outdoor main equipment is close to may trip the people, causes industrial accident; Thick and sharp keen hexagon head on big machinery both may collide with operator's head and health, bring potential safety hazard to production, also may cause very fearful accident.
Summary of the invention
Technical problem to be solved in the utility model is to provide paired hole, a kind of safe and reliable, convenient and practical termination bolt.
For addressing the above problem, paired hole, termination described in the utility model bolt is characterized in that: it comprises screw rod and the bolt head linked together; Be distributed with screw thread on one section of described screw rod or whole length; Have paired hole on described bolt head.
Described paired hole is diplopore or multipair hole.
The end that described bolt head is described screw rod, and described bolt head from end face along the described paired hole of axially having of described screw rod; Described paired hole is symmetrical in the end face center on described end face.
Described bolt head is the segment that is connected with described screw rod one end, on this spherical interior surface from spherical interior surface along the described paired hole of axially having of described screw rod; Described paired hole is symmetrical in the spherical interior surface center on described spherical interior surface.
Described bolt head is the cylinder I that is connected with described screw rod one end, on this cylinder I from end face along the described paired hole of axially having of described screw rod; Described paired hole is symmetrical in the end face center on described cylinder I end face; The length of described cylinder I is less than the length of described screw rod.
The dedicated spanner of paired hole, termination as above bolt, comprise handle and the fixed block, the movable block that are connected with described handle; The front end of described handle is respectively equipped with rotating shaft, chute, and its end is provided with uropore; The bottom of described movable block is provided with tooth bar, and this tooth bar is located in described chute; Described rotating shaft is provided with band tooth regulating wheel, and this band tooth regulating wheel is provided with tooth; Described tooth bar is meshed with described tooth, it is characterized in that: respectively be provided with a cylinder II on described fixed block and described movable block, this cylinder II is corresponding to described fixed block, described movable block one by one.
The utility model compared with prior art has the following advantages:
1, the end that in the utility model, bolt head is screw rod, be in the situation that the cross-sectional diameter of bolt total length is constant, eliminated traditional thick bolt head, but the bolt precession to bolt head end face and fixation flush even under and do not appear, the people is tripped to the potential safety hazard that causes tumble injury, industrial injury etc. thereby eliminated the conventional bolt head.
2,, in the situation that in the utility model, bolt head is segment, because segment does not have corner angle, and fixation is smooth-going transition to the bolt crown, thereby eliminated the conventional bolt head, the people tripped to the potential safety hazard that causes tumble injury, industrial injury etc.
3, in the situation that in the utility model, bolt head is short cylinder, because short cylinder does not have wedge angle, thus smoother around bolt head, reduced the conventional bolt head and the people has been tripped to the possibility that causes tumble injury, industrial injury etc.
4, the utility model is simple in structure, convenient and practical, with low cost.
