Abstract
The utility model discloses an anti-rotating bolt. The anti-rotating bolt comprises a bolt head and a screw rod, wherein a plurality of conic teeth projecting downward are distributed along the edge of the lower end surface of the bolt head and arranged with the bolt head into a whole, the upper end of the screw rod is arranged into a polished rod section, and the lower end of the screw rod is arranged into a threaded section. The anti-rotating bolt has a simple structure and is convenient to use. Due to the adoption of the design that the conic teeth projecting downward are arranged along the edge of the lower end surface of the bolt head, when the bolt is connected with a nut, the conic teeth act on the surface of a part among the conic teeth and apply a certain pressure on the surface of the part, the pressure becomes bigger and bigger along with the tightening of the nut, the phenomenon that the bolt rotates with the nut is effectively prevented from occurring, and the work efficiency is improved.
Description
Technical field
The utility model relates to a kind of mechanical fastener, is specially a kind of rotation inhibiting bolt.
Background technique
Bolt is widely used in the connection between the part as mechanical fastener.Generally, can the bolt head on the screw rod be fixed by spanner when screwing nut, when nut begins to screw, be unlikely to make screw rod and then to rotate like this.And under the operating conditions that has, such as the aerial power equipment of height, wherein also use bolt connection piece, inconvenient operation was not easy to vacate two hands usually and turned round a bolt simultaneously, like this when nut begins to screw this moment, bolt is followed nut easily and is rotated together, make nut disposablely not screw, prolonged the operating time, inefficiency.
The model utility content
The purpose of this utility model provides a kind of rotation inhibiting bolt, to solve bolt traditional in the prior art in use, follows nut easily and rotates together, makes nut disposablely not screw, and has prolonged the operating time, influences the problem of working efficiency.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of rotation inhibiting bolt includes bolt head and screw rod, it is characterized in that: there are several conical tooths that protrudes downwards described bolt head lower end surface along marginal distribution, and several conical tooths are an integral body with bolt head, is the polished rod section on the described screw rod, and the lower end is thread section.
Described a kind of rotation inhibiting bolt is characterized in that: described conical tooth quantity is at least three, and is evenly distributed on edge, bolt head lower end surface.
The beneficial effects of the utility model are:
The utility model is simple in structure, easy to use, employing arranges several conical tooths that protrude in the bolt head lower end surface downwards along the edge and designs, when making bolts and nuts connect, conical tooth acts on mutually with therebetween part surface, applies certain pressure, along with screwing of nut, this pressure is more big, has prevented that effectively bolt from following the generation of nut rotation phenomenon, has improved working efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of rotation inhibiting bolt includes bolt head 1 and screw rod 2, and there are several conical tooths 3 that protrudes downwards bolt head 1 lower end surface along marginal distribution, and several conical tooths 3 are an integral body with bolt head 1, and screw rod 2 upper ends are polished rod section 4, and the lower end is thread section 5.
Claims (2)
1. rotation inhibiting bolt, include bolt head and screw rod, it is characterized in that: there are several conical tooths that protrudes downwards described bolt head lower end surface along marginal distribution, and several conical tooths and bolt head are an integral body, described screw rod upper end is the polished rod section, and the lower end is thread section.
2. a kind of rotation inhibiting bolt according to claim 1, it is characterized in that: described conical tooth quantity is at least three, and is evenly distributed on edge, bolt head lower end surface.
