Abstract
The utility model provides a bolt capable of being effectively prevented from falling off. The bolt capable of being effectively prevented from falling off comprises a nut, a screw rod and threads, wherein the threads are arranged on the outer wall of the screw rod, the nut is fixedly connected with the screw rod through a connecting piece, the lower end of the screw rod is provided with a bolt head, the cross section of the bolt head is in an inverted trapezoidal shape, gaskets at two sides of the connecting piece are connected with a bolt cap which is arranged at the upper end of the nut, two sides of the bolt cap are provided with check blocks, and the outer wall of the connecting piece is provided with reinforcing ribs which are vertical to the gaskets. According to the bolt capable of being effectively prevented from falling off, provided by the utility model, the use is convenient, the corrosion of the bolt can be effectively prevented by the bolt cap, thus the bolt can be more durable, the service life of the bolt can be longer, and the bolt can be effectively prevented from falling off due to the bolt head which is arranged at the lower end of the screw rod.
Description
Technical field
The utility model relates to a kind of fastening piece, particularly a kind of bolt that comes off that effectively prevents.
Background technique
Bolt is by head and screw rod (with an externally threaded cylindrical body) class fastening piece dimerous, need coordinate with nut, for being fastenedly connected two parts with through hole, this Connecting format claims bolt to connect, as nut is screwed off from bolt, have and can make these two parts separately, therefore it is to belong to removably connect that bolt connects, nut is with interior threaded hole, shape generally manifests as flat hexagonal cylindricality, also has and is flat square column type or oblate cylindricality, fitted bolt, double-screw bolt or machine screw, for being fastenedly connected two parts, make it to become an integral body.
Be placed in outdoor or outdoor bolt and usually can cause the problem of getting rusty; for anti-getting rusty brushed paint; cause like this bolt to be difficult to dismounting; so not only to the maintenance man, brought very burden; common bolt is easy to drop in section groove, and is not easy to install, and traditional bolt strength is poor; fracture or the phenomenon that comes off easily occur, affected working life.
Summary of the invention
For addressing the above problem, the utility model discloses a kind of bolt that comes off that effectively prevents, this model utility is easy to use, can effectively prevent bolt corrosion and the problem that comes off, and this bolt long service life, low cost of manufacture.
The utility model provides a kind of bolt that comes off that effectively prevents, describedly prevent that effectively the bolt that comes off from comprising nut, screw rod, and be arranged on the screw thread on described screw rod outer wall, nut is fixedly connected with described screw rod by link, in the screw rod lower end, be provided with bolt head, the cross section of described bolt head is inverted trapezoidal, and the pad of link both sides connects the nuts that is arranged on the nut upper end, the both sides of nuts are provided with block, on the outer wall of link, are provided with the stiffening rib of vertical pad.A kind of bolt that comes off that effectively prevents of the purpose of this utility model design, this model utility is easy to use, the nuts that arranges effectively prevents the corrosion of bolt, and Durability is longer more to make bolt, and the bolt head that is arranged on the screw rod lower end effectively prevents bolt falling.
The utility model discloses a kind of a kind of improvement that effectively prevents the bolt that comes off, the width of described bolt head is greater than the diameter of described screw rod.The width of this improvement bolt head is greater than the diameter of described screw rod, and purpose is effectively to prevent coming off of bolt, and can also prevent effectively that bolt is stolen, needs special tool that bolt is turned on.
The utility model discloses a kind of a kind of improvement that effectively prevents the bolt that comes off, described block equates with the width of pad, and the glue of described block and pad bonding is epoxy resin.This improvement block equates with the width of pad, and purpose is the intensity that strengthens bolt, is that bolt is more durable, longer service life.
A kind of bolt that comes off that effectively prevents of the purpose of this utility model design, this model utility is easy to use, the nuts that arranges effectively prevents the corrosion of bolt, Durability is longer more to make bolt, the bolt head that is arranged on the screw rod lower end effectively prevents bolt falling, this bolt low cost of manufacture, ageing resistance is strong.
