Abstract
The invention discloses an anti-falling bolt assembly which comprises a bolt assembly. A circular groove is formed on a screw of the bolt assembly close to the outer end. The depth of the groove is greater than the root diameter of a thread, and the width of the groove is greater than the thickness of the nut. According to the anti-falling bolt assembly provided by the invention, after the nut looses, the anti-falling bolt assembly just falls into an anti-falling groove, so that components are prevented from separately falling into materials in a machine effectively, and the operational safety and product quality are guaranteed.
Description
Technical field:
The present invention relates to bolt, particularly the anti-drop bolt assembly used of a kind of fastening or mounting article and mechanical parts.
Background technique:
Existing bolt assembly all is to be combined with a nut with screw thread rotation on a screw rod, and the screw rod between bolt head and nut is furnished with packing ring.The problem that this traditional bolt assembly exists is, in use because of vibration or friction occur loosening after, easily nut is split away off from screw rod, fall in procedure or the material, when particularly in medicine and food service industry, using, have influence on job safety and quality of product.
Summary of the invention:
Can not break away from screw rod after the purpose of this invention is to provide a kind of nut loosening, prevent that effectively bolt assembly from use falling into the anticreep bolt assembly in the material in the machine.
Technological scheme of the present invention is finished as follows, a kind of anticreep bolt assembly, it includes a bolt assembly, it is characterized in that: have an annular groove near the outer end on the screw rod of bolt assembly, the degree of depth of groove is greater than core diameter of thread, and the width of groove is greater than the thickness of nut.
The present invention can only be shed to behind nut loosening in the anticreep groove of screw rod, prevents that effectively each assembly from separately falling in the material in the machine, guarantees job safety and quality of product.
Description of drawings:
Fig. 1 is structural representation of the present invention, and Fig. 2 is the structural representation of nut when coming off.
Embodiment:
The present invention is improvements over the prior art, it includes a bolt assembly that is comprised of the screw rod 2 of strap bolt head 1 and nut 4 thereof and packing ring 3, main improvement is to have an annular groove 5 near the outer end on screw rod, the degree of depth of groove is greater than core diameter of thread, and the width of groove is greater than the thickness of nut.When work, loosening outside slippage occurs in parts 6 vibrations even nut is fixed, and can only drop in the annular groove, has effectively prevented from falling into after screw rod from separating with its assembly disengaging the material in the machine.
Claims (1)
