Abstract
The utility model provides a screw with a convex point. The screw comprises a screw head and a screw rod. A connection piece is arranged between the screw head and the screw rod, self-tapping threads are arranged on the periphery of the screw rod, and a protruding block is arranged on the connection piece and is in an inverse-triangle shape. According to the screw with the convex point, through the convex point, the screw can easily penetrates into a hard wood block and can not fall down easily due to vibration of a machine, and through the self-tapping threads, the screw can easily penetrates deeply into an object.
Description
Technical field
The utility model relates to a kind of fastening piece, particularly a kind of screw with spur.
Background technique
Fastening piece is also referred to as standard piece in market, that two or more parts (or member) are fastenedly connected the general name that becomes class mechanical parts that adopt when whole, its feature is that description is various, the performance purposes is different, and standardization, seriation, unitized strong.Fastening piece is most widely used mechanical basic part, is in great demand.
Common screw is with object fixedly the time, if fix or be subjected to for a long time the vibration of machine, the phenomenon that usually comes off, cause the fault of machine, affected the working life of machine, general screw needs very large power that screw and object are fixed, but also the phenomenon of fracture easily occurs.
Summary of the invention
For addressing the above problem, the utility model discloses a kind of screw with spur, the setting of spur makes screw more easily go deep into the hard wooden unit, and do not allow to be subject to machine vibration and come off, the setting of Thread Forming TF makes screw can more easily go deep into object, fixation.
The utility model provides a kind of screw with spur, comprises screw head, screw rod, is provided with link between described screw head and screw rod, is provided with Thread Forming TF in described screw rod outer rim, and described link is provided with projection, and described projection is del.A kind of screw with spur of the purpose of this utility model design, the setting of spur makes screw more easily go deep into the hard wooden unit, and do not allow to be subject to machine vibration and come off, the setting of Thread Forming TF, make screw can more easily go deep into object, this model utility is simple in structure, easy to use, and fabricating cost is low.
The utility model discloses a kind of a kind of improvement of the screw with spur, described projection is arranged on the outer ring of described link.This improvement is arranged on projection the outer ring of link, and purpose makes screw can more easily go deep into object, the convenient use.
The utility model discloses a kind of a kind of improvement of the screw with spur, described projection is at least 3.This improvement is at least 3 with the projection setting, and purpose makes screw more easily go deep into the hard wooden unit, improves the working efficiency of screw.
The utility model discloses a kind of a kind of improvement of the screw with spur, described link is trapezoidal.This improvement link is set to trapezoidal, and purpose makes screw can stablize fixed object.
A kind of screw with spur of the purpose of this utility model design, the setting of spur makes screw more easily go deep into the hard wooden unit, and do not allow to be subject to machine vibration and come off, the setting of Thread Forming TF, make screw can more easily go deep into object, this model utility is simple in structure, easy to use, and fabricating cost is low.
