Abstract
The utility model discloses an antiskid bolt which comprises a bolt head and a screw rod, wherein a conical transitional skew wall is arranged between the lower end of the bolt head and the screw rod; a plurality of antiskid convex ribs are symmetrically distributed on the transitional skew wall along the axis of the bolt head; a polished rod section is arranged at the upper end of the screw rod; a thread section is arranged at the lower end of the screw rod; and a concave hole is formed in the end part of the screw rod and is an inner quadrangular or inner hexagonal concave hole. The antiskid bolt disclosed by the utility model is simple in structure and is convenient to mount and use; due to the adoption of the design that the transitional skew wall is arranged between the bolt head and the screw rod and the antiskid convex ribs are arranged on the transitional skew wall, the grabbing force of the bolt to a mounting surface is effectively improved, the probability that the bolt slides due to the vibration is reduced; and due to the adoption of the design that the concave hole is formed in the end part of the screw rod, the screw rod can be fixed by using a tool during mounting, the linkage phenomenon is effectively avoided and the work efficiency is increased.
Description
Technical field
The utility model relates to a kind of mechanical fastener, is specially a kind of anti-skidding bolt.
Background technique
Bolt generally is used for fastening, location, in use can make the bolt sliding transfer because of reasons such as vibrations, some non-skid feature will be based upon on the fastened basis of bolt, such as elastic washer, but in the application that prevents from being shifted, because bolt does not possess fastened condition, a lot of anti-skidding measures can't be used, and bolt is followed the nut interlock when mounted easily, and nut can not disposablely screw, and influences working efficiency.
The model utility content
The purpose of this utility model provides a kind of anti-skidding bolt,, and follows nut easily when installing and links because former thereby easy slippages such as vibrations to solve bolt traditional in the prior art in use, influences the problem of fastening effect and fitting operation.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of anti-skidding bolt, include bolt head and screw rod, it is characterized in that: be provided with the conical transition skew wall between described bolt head lower end and the screw rod, described transition skew wall upper edge bolt head axis is symmetrically distributed with several anti-skidding convex tendons, described screw rod upper end is the polished rod section, the lower end is thread section, and described screw rod end is provided with shrinkage pool, and described shrinkage pool is interior four jiaos or interior hexagonal shrinkage pool.
Described a kind of anti-skidding bolt is characterized in that: described bolt head upper end is hexagon.
Described a kind of anti-skidding bolt is characterized in that: described transition skew wall upper edge skew wall stringcourse is provided with annular anti-skidding convex tendon.
The beneficial effects of the utility model are:
The utility model is simple in structure, easy to install, adopt the transition skew wall is set between bolt head and screw rod, and the design of anti-skidding convex tendon is set at the transition skew wall, promote the grasping force of bolt for attachment face effectively, made bolt not be subject to influence of vibration and sliding phenomenon takes place; Employing arranges the design of shrinkage pool in the screw rod end, can fix screw rod by instrument during installation, has avoided the generation of interlock phenomenon effectively, 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 anti-skidding bolt, include bolt head 1 and screw rod 2, be provided with conical transition skew wall 3 between bolt head 1 lower end and the screw rod 2, transition skew wall 3 upper edge bolt heads 1 axis is symmetrically distributed with several anti-skidding convex tendons 4, and screw rod 2 upper ends are polished rod section 5, and the lower end is thread section 6, screw rod 2 ends are provided with shrinkage pool 7, and shrinkage pool 7 is interior four jiaos or interior hexagonal shrinkage pool.
Bolt head 1 upper end is hexagon, and transition skew wall 3 upper edge skew wall stringcourses are provided with annular anti-skidding convex tendon 8.
