And in the life of reality, because the operating of machinery shakes, workpiece occurs loosening, it is necessary to often tight in screw and nut junction
Gu nut, so getting off wastes time and energy, and wastes time, and then causes production efficiency to reduce, then how to reduce production process
In often fastening screw turn into people it is to be resolved the problem of.Therefore, a kind of screw with slotted will be provided by needing badly.
Utility model content
The purpose of this utility model is to provide a kind of screw with slotted, to solve the problems mentioned in the above background technology.
To achieve the above object, the utility model provides following technical scheme：
Connected in the middle part of a kind of screw with slotted, including lead screw, one end of the lead screw and the bottom surface of screw terminal, the spiral shell
A side wall of the screw mandrel away from screw terminal is provided with the screw fluting on vertical direction, and the bottom surface of the screw terminal is wear-resisting with buffering
The top surface of pad is seamless contact, and the buffering wear-resistant pad is connected through a screw thread with lead screw, and the buffering wear-resistant pad is provided with edge
Several shock relieve vents of circumferentially equidistant distribution.
It is preferred that, the one end of the lead screw away from screw terminal is provided with lead, and lead is in circular arc or truncated cone-shaped.
It is preferred that, the quantity of screw fluting to be one or more along the circumferentially equidistant distribution of lead screw, and screw fluting
Shapes and sizes it is constant and extend on lead from bottom land and notch.
It is preferred that, the lead and screw terminal are structure as a whole with lead screw.
It is preferred that, the screw terminal uses hexagon screw terminal or hexagon socket head cap screw head or with open screw fluting
Screw terminal.
Compared with prior art, the beneficial effects of the utility model are：The utility model in lead screw by being provided with spiral shell
Silk fluting, and the quantity of screw fluting is one or more along the circumferentially equidistant distribution of lead screw, changes traditional fastened by screw
Part needs the situation that frequent clamp nut loosens to ensure workpiece to be difficult, due to slow provided with seamless contact in the bottom surface of screw terminal
Rush wear-resistant pad so that coefficient is fastened between lead screw and workpiece and is increased, eventually through nut so that workpiece is close by screw
Connection, improve reinforcing and locking property, and shock relieve vent is provided with buffering wear-resistant pad so that shook in the operating of machinery
The effect of damping can be played in journey.The utility model have it is simple in construction, easily manufactured, with low cost, reinforce locking etc. excellent
Point, is conducive to preventing that whole screw from producing the purpose of fictitious force square during assembling with nut, while being also beneficial to ensure spiral shell
The service life of silk is extended, so as to increase the Reusability of whole screw.
Brief description of the drawings
Fig. 1 is the utility model structural representation；
Fig. 2 is the utility model structure upward view.
In figure：1 lead screw, 2 screw terminals, 3 screws fluting, 4 buffering wear-resistant pads, 5 shock relieve vents, 6 leads.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：
A kind of screw with slotted, including lead screw 1, one end of lead screw 1 in the middle part of the bottom surface of screw terminal 2 with being connected, lead screw 1
One end away from screw terminal 2 is provided with lead 6, and lead 6 is in circular arc or truncated cone-shaped, is easy to play a part of guiding, leads
It is structure as a whole to post 6 and screw terminal 2 with lead screw 1, improves fastness, screw terminal 2 uses hexagon screw terminal
Hexagon socket head cap screw head or with open screw slot screw terminal, with Mutiple Choice, lead screw 1 away from screw terminal 2 one
Side wall is provided with the screw fluting 3 on vertical direction, and the quantity of screw fluting 3 is one or more circumferential etc. along lead screw 1
Away from distribution, and the shapes and sizes of screw fluting 3 are constant and extend on lead 6 from bottom land and notch, by increasing capacitance it is possible to increase screw
Tightness between nut, plays the effect reinforced and loosened, and the bottom surface of screw terminal 2 is seamless with the top surface for buffering wear-resistant pad 4
Contact, buffering wear-resistant pad 4 is connected through a screw thread with lead screw 1, convenient for assembly, and buffering wear-resistant pad 4 is provided with circumferentially equidistant point
Several shock relieve vents 5 of cloth, facilitate firm between screw and workpiece, the service life of screw are also can guarantee that, while can also increase
Plus the Reusability of screw.
The utility model in lead screw 1 by being provided with screw fluting 3, and the quantity of screw fluting 3 is one or more
Along the circumferentially equidistant distribution of lead screw 1, changing traditional screw fastener needs frequent clamp nut to ensure that workpiece is difficult pine
