Abstract
The utility model discloses an anti-rotating and easily-dismounted bolt. The anti-rotating and easily-dismounted bolt comprises a bolt head and a screw rod, wherein a plurality of conic teeth projecting downward are arranged 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, the lower end of the screw rod is arranged into a threaded section, and a shallow groove which is parallel with the axis of the screw rod is formed in the threaded section. The anti-rotating and easily-dismounted bolt has a simple structure and is convenient to use. The phenomenon that the bolt rotates with a nut is effectively prevented from occurring, and the work efficiency is improved. Due to the adoption of the design that the shallow groove is formed in the threaded section of the screw rod, lubricating oil can be filled from the part of the shallow groove when the bolt is difficult to dismount because the bolt becomes rusted, so that dismounting operation is effectively facilitated.
Description
Technical field
The utility model relates to a kind of mechanical fastener, is specially the quick detachable bolt of a kind of rotation inhibiting.
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, this moment inconvenient operation, usually be not easy to vacate two hands and turn round a bolt simultaneously, when nut began to screw, bolt was followed nut easily and is rotated together like this, make nut disposablely not screw, prolonged the operating time, inefficiency, and after long-time the use, bolt is fixed together with nut because getting rusty easily, and dismounting is convenient inadequately.
The model utility content
The purpose of this utility model provides the quick detachable bolt of a kind of rotation inhibiting, to solve bolt traditional in the prior art in use, following nut easily rotates together, make nut disposablely not screw, prolong the operating time, influenced working efficiency, and after long-time the use, bolt is fixed together with nut because getting rusty easily, dismantles inadequately problem easily.
For achieving the above object, the technical solution adopted in the utility model is:
The quick detachable bolt of a kind of rotation inhibiting, include bolt head and screw rod, it is characterized in that: the conical tooth that described bolt head lower end surface has several to protrude downwards along marginal distribution, and several conical tooths and bolt head are an integral body, described screw rod upper end is the polished rod section, the lower end is thread section, and described thread section is provided with the shallow slot parallel with screw axis.
The quick detachable bolt of described a kind of rotation inhibiting is characterized in that: described conical tooth quantity is at least three, and is evenly distributed on edge, bolt head lower end surface.
The quick detachable bolt of described a kind of rotation inhibiting, it is characterized in that: described shallow slot is at least one, and the shallow slot degree of depth is 1-3mm.
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; Employing arranges the design of shallow slot in the screw flight section, when not quick detachable because get rusty when bolt, can add lubricant oil from shallow slot, thereby make things convenient for disassembling section effectively.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the quick detachable bolt of a kind of rotation inhibiting, include bolt head 1 and screw rod 2, the conical tooth 3 that bolt head 1 lower end surface has several to protrude downwards along marginal distribution, and several conical tooths 3 are an integral body with bolt head 1, screw rod 2 upper ends are polished rod section 4, and the lower end is thread section 5, and thread section 5 is provided with the shallow slot 6 parallel with screw rod 2 axis.
Conical tooth 3 quantity are at least three, and are evenly distributed on edge, bolt head 1 lower end surface.
Shallow slot 6 is at least one, and shallow slot 6 degree of depth are 1-3mm.
Claims (3)
1. quick detachable bolt of rotation inhibiting, include bolt head and screw rod, it is characterized in that: the conical tooth that described bolt head lower end surface has several to protrude downwards along marginal distribution, and several conical tooths and bolt head are an integral body, described screw rod upper end is the polished rod section, the lower end is thread section, and described thread section is provided with the shallow slot parallel with screw axis.
