Abstract
The utility model discloses an efficient anti-linkage bolt. The efficient anti-linkage 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; and a concave hole is formed in the end part of the lower end of the screw rod, and the concave hole is an internal quadrangular or internal hexagonal concave hole. The efficient anti-linkage 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 and the concave hole is formed in the end part of the screw rod, the phenomenon that the bolt rotates with a nut can be 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 efficient anti-interlock 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 may and then rotate, make nut disposablely not screw, prolonged the operating time, inefficiency.
The model utility content
The purpose of this utility model provides a kind of efficient anti-interlock bolt, to solve bolt traditional in the prior art in use, may follow nut to rotate 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 efficient anti-interlock bolt, 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 end, described screw rod lower end is provided with shrinkage pool, and described shrinkage pool is interior four jiaos or interior hexagonal shrinkage pool.
Described a kind of efficient anti-interlock bolt, it 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, make when 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; Employing arranges the design of shrinkage pool in the screw rod end, can be stuck in the shrinkage pool by instrument when bolting on, and further prevents the bolts and nuts interlock, 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 efficient anti-interlock bolt, 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, and screw rod 2 upper ends are polished rod section 4, and the lower end is thread section 5, end, screw rod 2 lower end is provided with shrinkage pool 6, and shrinkage pool 6 is interior four jiaos or interior hexagonal shrinkage pool.
Claims (2)
1. efficiently prevent the interlock bolt for one kind, 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 end, described screw rod lower end is provided with shrinkage pool, and described shrinkage pool is interior four jiaos or interior hexagonal shrinkage pool.
2. a kind of efficient anti-interlock 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.
