Abstract
The utility model discloses an antiskid anticorrosion 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; an insulating layer made of a soft material is wound on the outer surface of the polished rod section; 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 anticorrosion bolt disclosed by the utility model is simple in structure and is convenient to mount and use; the grabbing force of the bolt to a mounting surface is effectively improved, so that the probability that the bolt slides due to the vibration is reduced, the linkage phenomenon is avoided and the work efficiency is increased; and in addition, the antiskid anticorrosion bolt has a better anticorrosion performance and a long service life and ensures the safe operation of the equipment.
Description
Technical field
The utility model relates to a kind of mechanical fastener, is specially the corrosion-resistant bolt of a kind of skidproof type.
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, nut can not disposablely screw, and influences working efficiency, and corrosion-resistant, be subjected to corrosion to influence and lost efficacy easily, and then influence the use safety of equipment.
The model utility content
The purpose of this utility model provides the corrosion-resistant bolt of a kind of skidproof type, to solve bolt traditional in the prior art in use because former thereby easy slippages such as vibrations, follow the nut interlock during installation easily, influence fastening effect and fitting operation, and corrosion-resistant, be subjected to corrosion to influence and lost efficacy easily, and then influence the problem of the use safety of equipment.
For achieving the above object, the technical solution adopted in the utility model is:
The corrosion-resistant bolt of a kind of skidproof type, 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, and the lower end is thread section, is wound with the isolation layer that soft material constitutes on the described polished rod section outer surface, described thread section end is provided with shrinkage pool, and described shrinkage pool is interior four jiaos or interior hexagonal shrinkage pool.
The corrosion-resistant bolt of described a kind of skidproof type is characterized in that: described bolt head upper end is hexagon.
The corrosion-resistant bolt of described a kind of skidproof type is characterized in that: described isolation layer is the soft adhesive tape of insulation.
The corrosion-resistant bolt of described a kind of skidproof type 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; The design of the isolation layer of soft material formation is twined in employing at screw rod polished rod section outer surface, prevented the interior residual corrosive gas of screw or liquid effectively and bolt has been caused the corrosion influence, promote the antiseptic property of bolt, prolonged working life, guaranteed the safe operation of equipment.
