Abstract
The utility model provides anti-theft bolts which are formed by providing a certain of longitudinal groove on the common bolts and nuts. The method of fixing objects is the same as that of the common bolts, except adjusting one longitudinal groove on the screw hat to cooperate with one longitudinal groove on the screw, then, a square peg is inserted in the grooves. The root of the square peg will be cut for preventing being thieved and the nut hat will be unable to rotate or move; the root of the square peg will be reserved for preventing loosing and the screw hat can be rotated by moving away the square peg. Thus, the functions of anti-theft and anti-loose are all performed.
Description
One, technical field
The utility model relates to a kind of securing means of object, especially relates to the antitheft and anti-loosening anti-theft bolt of a kind of energy.
Two, background technique
At present, known bolt is made up of screw and nut.When connecting object, the object that will connect has bored the hole earlier, then screw is penetrated, and the nut of screwing on is tightened nut again, and object has connected with regard to fastened.But the connection of this bolt can not be antitheft and anti-loosening, often causes some public place objects stolen, or coping screw loosening and some mechanical accidents occur.
Three, model utility content
The purpose of this utility model is to overcome the deficiency that existing bolt can not be antitheft and anti-loosening, thus provide a kind of not only can fastening object, and novel anti-theft bolt that can also be antitheft and anti-loosening.
This anti-theft bolt is achieved by the following technical solution: it is to open several longitudinal flutings on common screw and nut, when fastening object, identical with the usage of plain bolt, certain bar longitudinal fluting on the nut is alignd with certain bar longitudinal fluting on the screw, a square pin can be knocked in the groove.As antitheft, then that the neat undercut of square pin is disconnected, nut again can not rotate and dismantle; As anti-loosening, then with surplus one section of square pin root, in the time of will dismantling later on, can rotating screw cap as long as square pin is just extracted.So just can reach the antitheft and anti-loosening purpose of energy.
Anti-theft bolt according to technique scheme is made in fastening article, reaches antitheft and anti-loosening purpose easily, is characterized in opening several longitudinal flutings and with a square pin, simple in structure like this, effect is more outstanding on screw and nut.
Four, description of drawings
The nut structure schematic representation of Fig. 1, anti-theft bolt of the present utility model.
The screw structural schematic representation of Fig. 2, anti-theft bolt of the present utility model.
Schematic representation after Fig. 3, anti-theft bolt of the present utility model are installed.
Among the figure: 1-nut, 2-screw, 3-square pin.
Five, embodiment
Below in conjunction with drawings and Examples anti-theft bolt of the present utility model is described further.
As shown in Figure 1 and Figure 2: anti-theft bolt of the present utility model, it is respectively to open several longitudinal flutings on common screw 2 and nut 1, when fastening object, identical with the usage of plain bolt, certain bar longitudinal fluting on the nut 1 is alignd with certain bar longitudinal fluting on the screw 2, then, shown in Figure 3, again square pin 3 is knocked in the groove.As antitheft, then that square pin 3 neat undercuts are disconnected, nut 1 again can not rotate and dismantle; As anti-loosening, then with surplus one section of square pin 3 roots, in the time of will dismantling later on, can rotating screw cap 1 as long as square pin 3 is just extracted.So just can reach the antitheft and anti-loosening purpose of energy.
