Embodiment
In order to there be understanding clearly to technical characteristics of the present utility model, object and effect, now contrast accompanying drawing and embodiment of the present utility model is described.
As Figure 1-Figure 4, the utility model proposes a kind of anti-theft bolt component, comprise sleeve 1 and bolt 2, one end of sleeve 1 is opening end, the other end of sleeve 1 is provided with through hole 11, and the radius of through hole 11 is less than the radius of the head 21 of bolt 2, and the radius of through hole 11 is more than or equal to the radius of the screw rod 22 of bolt 2, screw rod 22 is located at the side of head 21, and the opposite side eccentric setting of head 21 has pin 23; The head 21 of bolt 2 is sheathed in sleeve 1 and the screw rod 22 of bolt 2 can pass through hole 11 be located at outside sleeve 1.
When anti-theft bolt component of the present utility model uses, the head 21 of bolt 2 is positioned at sleeve 1, and screw rod 22 is connected with oil pumping unit reduction gearbox port lid, because the opposite side eccentric setting of head 21 has pin 23, therefore use common instrument, cannot stretch in sleeve 1, and open the bolt 2 being provided with pin 23, thus effectively prevent malice from opening the behavior of port lid, stop stealing of speed reduction gear box oil.
The head 21 of bolt 2 is cylindricality, and screw rod 22 and head 21 are coaxially arranged, the axis of pin 23 and the axis being parallel of head 21, the axis of the axis runout head 21 of pin 23.Through hole 11 and sleeve 1 concentric of sleeve 1 are arranged.In a concrete mode of execution, the head 21 of bolt 2 is cylindrical.
The internal diameter of sleeve 1 is 25% to 40% of head 21, and the axial length of sleeve 1 is 2 times of head 21 length to 3 times.In the present embodiment, the internal diameter of sleeve 1 is 30% of head 21, and the axial length of sleeve 1 is 210% of head 21 length.
The utility model also proposed a kind of with described anti-theft bolt component with the use of spanner 3, spanner 3 comprises inserted link 31, one end of inserted link 31 is provided with the groove 311 matched with head 21 and pin 23, one end of spanner 3 can insert sleeve 1 opening end and with the corresponding grafting of head 21 of bolt 2.During use, spanner 3 is stretched into the opening end of sleeve 1, and with the corresponding grafting of head 21 of bolt 2, drive bolt 2 rotational fastener by rotary spanner 3 or take off.
In a concrete mode of execution, inserted link 31 is cylindric.The force application rod 32 that inserted link 31 can be made to rotate is provided with at the other end of inserted link 31.Particularly, the other end of inserted link 31 has been disposed radially the first through hole 312, and the radius of force application rod 32 is less than or equal to the radius of the first through hole 312, and force application rod 32 can insert the first through hole 312 and drive force application rod 32 to rotate.By rotation urging bar 32, thus band wrench 3 turn bolt 2, to save manpower.
