Abstract
The utility model discloses an anti -theft screw, including nut and double -screw bolt, the nut is including dismantling the hexagon head and the button head of connection, the double -screw bolt is located the button head and is kept away from on the one end terminal surface of hexagon head, the button head is provided with a plurality of recesses back to the one end terminal surface of double -screw bolt on, be provided with the lug with the recess one -to -one on the hexagon head, recess and lug cooperation aim at providing an anti -theft screw, and it has convenient to use, and simple structure avoids the screw by the random advantage of dismantling of people.
Description
Technical field
The utility model relates to a kind of fastening piece, and more particularly, it relates to a kind of anti-theft screw.
Background technique
What we used at present is mostly the screw adopting NBS, it is tightened or dismantles is all as spanner by conventional tool, four word screw-drivers etc. turn nut to realize, it is very convenient that this makes screw use, install, dismounting easily, but certain safety problem can be caused due to its easy-off characteristic on some special occasions and special article, such as railway, highway bridge, electric power pylon, microwave communication tower, in the facilities such as door and window, because standard screws can disassemble easily, therefore, often by lawless person as theft or destroy object, cause the hidden danger that is absolutely unsafe to these Infrastructure or directly destroyed.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of anti-theft screw.
For achieving the above object, the utility model provides following technological scheme: a kind of anti-theft screw, comprise nut and stud, described nut comprises the hexagon head and round end that removably connect, described stud is located at round end away from one end end face of hexagon head, described round end is provided with multiple groove on one end end face of stud, and described hexagon head is provided with and groove projection one to one, described groove coordinates with projection.
By adopting technique scheme, nut is divided into the hexagon head removably connected and round end, stud is arranged on round end, need tighten or knockout screw time, round end is driven to rotate realization by rotating hexagon head, and be removably connected due to hexagon head and round end, do not need to take off hexagon head during dismounting after tightening, and the utility model uses the cooperation of multiple groove and projection to realize detachable and synchronous axial system, the groove be arranged on round end does not belong to standard piece structure, conventional tool cannot be used to dismantle it, this vibrational power flow can effectively avoid screw easily to dismantle the potential safety hazard caused.
The utility model is set to further: described groove is uniformly distributed around round end shaft axis, described round end is provided with the cylindrical cavity with round end coaxial inner conductor, the described cylindrical cavity degree of depth is greater than round end thickness, on described hexagon head, corresponding circle cylindricality empty cavity position is provided with attachment post, and described cylindrical cavity coordinates with attachment post.
By adopting technique scheme, due to the thinner thickness of nut, in the utility model, again nut is divided into two-part, therefore realize connection only by groove and the cooperation of projection and round end can be made with hexagon head and be easily separated, cause tightening and use inconvenience in unloading process, in order to avoid above problem, the utility model arranges the cylindrical cavity that a degree of depth is greater than round end thickness in round end central position, and an attachment post is set on hexagon head is connected with cylindrical cavity, round end is connected with hexagon head more reliable, facilitates tightening and dismantling of screw.
The utility model is set to further: described groove is cylindrical.
By adopting technique scheme, the groove of cylindrical setting is convenient for production and easily realize the cooperation of hexagon head and round end.
The utility model is set to further: one end end face of described hexagon head round end is dorsad provided with well.
By adopting technique scheme, end face arranging well and makes this screw go for multiple standards tool ejector and tighten.
In sum, the utility model anti-theft screw has easy to use, and structure is simple, avoids the advantage that screw is arbitrarily dismantled by people.
Accompanying drawing explanation
Fig. 1 is the structural representation of anti-theft screw;
Fig. 2 is the fractionation structural representation of anti-theft screw;
Fig. 3 is the structural representation of hexagon head.
Reference character: 1, nut; 11, hexagon head; 111, well; 112, projection; 113, attachment post; 12, round end; 121, groove; 122, cylindrical cavity; 2 studs.
Embodiment
Referring to figs. 1 through Fig. 3, the utility model anti-theft screw is described further.
As depicted in figs. 1 and 2, for a kind of mode of execution of a kind of anti-theft screw of the utility model, it comprises nut 1 and stud 2, this nut 1 includes hexagon head 11 and round end 12, hexagon head 11 and round end 12 removably connect, and connect after hexagon head 11 and round end 12 synchronous axial system, stud 2 is located at round end 12 away from one end end face of hexagon head 11.
Round end 12 is provided with multiple groove 121 on one end end face of stud 2, and this groove 121 is cylindrical, and the groove 121 of cylindrical setting is convenient for production and easily realize the cooperation of hexagon head 11 and round end 12.This mode of execution further groove 121 quantity selects four, and groove 121 is uniformly distributed around round end 12 shaft axis, and hexagon head 11 is provided with and groove 121 projection 112 one to one, groove 121 coordinates with projection 112.
One end end face of hexagon head 11 round end 12 is dorsad provided with well 111, and well 111 can be straight groove, cross recess or hex slot, end face arranges well 111 and makes this screw go for multiple standards tool ejector and tighten.
In addition, due to the thinner thickness of nut 1, in the utility model, again nut 1 is divided into two-part, therefore realize connection only by groove 121 and the cooperation of projection 112 and round end 12 can be made with hexagon head 11 and be easily separated, cause tightening and use inconvenience in unloading process, in order to avoid above problem, the utility model is provided with the cylindrical cavity 122 with round end 12 coaxial inner conductor on round end 12, cylindrical cavity 122 degree of depth is greater than round end 12 thickness, on hexagon head 11, corresponding circle cylindrical cavity 122 position is provided with attachment post 113, cylindrical cavity 122 coordinates with attachment post 113, round end 12 is made to be connected more reliable with hexagon head 11 by this structure, facilitate tightening and dismantling of screw.
By adopting technique scheme, nut is divided into the hexagon head 11 and round end 12 that removably connect, stud 2 is arranged on round end 12, need tighten or knockout screw time, round end 12 is driven to rotate realization by rotating hexagon head 11, and be removably connected with round end 12 due to hexagon head 11, do not need to take off hexagon head 11 during dismounting after tightening, and the utility model uses the cooperation of multiple groove 121 and projection 112 to realize detachable and synchronous axial system, the groove 121 be arranged on round end 12 does not belong to standard piece structure, conventional tool cannot be used to dismantle it, this vibrational power flow can effectively avoid screw easily to dismantle the potential safety hazard caused.
The above is preferred implementation of the present utility model, and under not departing from the prerequisite of the utility model principle for the person of ordinary skill of the art, can also make some modification and improvement, these also should be considered as protection domain of the present utility model.
