Abstract
The invention relates to an end grooving bolt. The end grooving bolt comprises a screw rod and bolt head connected to each other; one section of or the whole screw rod is distributed with threads; a groove is formed in the bolt head; by taking the axis of the screw rod as the symmetrical axis, the groove is unchanged in size and shape from the groove opening to the groove bottom. The end grooving bolt is simple in structure, convenient, practical and low in cost and eliminates the safety loopholes such as fall damage and industrial injury as a person is tripped over by the traditional bolt head.
Description
Technical field
The present invention relates to a kind of fastening piece and kit thereof, relate in particular to termination slotting bolt and dedicated spanner thereof.
Background technique
Walk on road limit, be slowly close to, take a broad view in equipment and on lathe, all can see hexagon head bolt and square head bolt, they are the most frequently used fastening pieces that connect 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 people trip sometimes, even by people's tumble injury; The thick hexagon head that indoor and outdoor main equipment is close to may trip 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 by this invention is to provide a kind of safe and reliable, convenient and practical termination slotting bolt and dedicated spanner thereof.
For addressing the above problem, termination of the present invention slotting bolt, is characterized in that: it comprises the screw rod and the bolt head that link together; In one section of described screw rod or whole length, be distributed with screw thread; On described bolt head, have groove; Described groove is take the axle of described screw rod as symmetry axis, and its size and shape is constant to bottom land from notch.
Described groove is single groove or multiple-grooved.
Described bolt head is one end of described screw rod, and described bolt head axially has the described groove take the axle of described screw rod as symmetry axis from end face along described screw rod.
Described bolt head is the segment being connected with described screw rod one end, on this segment, axially has the described groove take the axle of described screw rod as symmetry axis from spherical interior surface along described screw rod.
Described bolt head is the cylinder I being connected with described screw rod one end, in this cylinder I, axially has the described groove take the axle of described screw rod as symmetry axis from end face along described screw rod; The length of described cylinder I is less than the length of described screw rod.
The dedicated spanner of termination as above slotting bolt, comprises 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: on described fixed block and described movable block, be respectively provided with a cylinder II, this cylinder II is corresponding to described fixed block, described movable block one by one.
The present invention compared with prior art has the following advantages:
1, one end (cross-sectional diameter that is bolt total length is constant) that in the present invention, bolt head is screw rod, eliminate traditional thick bolt head, bolt can precession to bolt head end face and fixation flush even under and do not appear, people is tripped to the potential safety hazard that causes tumble injury, industrial injury etc. thereby eliminated conventional bolt head.
2,, in the situation that in the present invention, bolt head is segment, because segment does not have corner angle, and fixation is smooth-going transition to the bolt crown, people tripped to the potential safety hazard that causes tumble injury, industrial injury etc. thereby eliminated conventional bolt head.
3,, in the situation that in the present invention, bolt head is short cylinder, because short cylinder does not have wedge angle, thereby bolt head is smoother around, has reduced conventional bolt head and people has been tripped to the possibility that causes tumble injury, industrial injury etc.
4, the present invention is simple in structure, convenient and practical, with low cost.
