Abstract
A kind of anti-theft bolt, be made up of nut-protecting sleeve (2), locking nut (4), screw (8), screw (8) is through joint (7), and the presser feet (5) on locking nut (4) is pressed in connection portion (7), and nut-protecting sleeve (2) covers locking nut (4); The cylindrical wall of nut-protecting sleeve (2) is at least provided with 3 semicircular pins (3), offers the circular hole (K) that can pass screw (8) in the bottom of the cylinder of nut-protecting sleeve (2).
Description
Technical field
The utility model relates to fastener technology, specifically relates to a kind of bolt.
Background technique
Plain bolt is made up of screw and nut, no matter bolt is generally all play connection and fixation at mechanical field or in our daily life,, so there is equipment and some Infrastructure is easy to stolen situation in the feature that it has relatively good installation and unloads.The stolen meeting of some equipment brings huge economic loss to our country and unit, has certain anti-theft feature and structure simple bolt demand is larger so a.
Summary of the invention
The purpose of this utility model is to provide a kind of anti-theft bolt.
The utility model is a kind of anti-theft bolt, is made up of nut-protecting sleeve 2, locking nut 4, screw 8, and screw 8 is through joint 7, and the presser feet 5 on locking nut 4 is pressed in connection portion 7, and nut-protecting sleeve 2 covers locking nut 4; The cylindrical wall of nut-protecting sleeve 2 is at least provided with 3 semicircular pins 3, and offering in the bottom of the cylinder of nut-protecting sleeve 2 can through the circular hole K of screw 8.
The beneficial effects of the utility model are: be difficult to the bolt of locking to open by traditional method; protect the possibility of formula theft of spiriting away; even if violence is tolled breakdown also increase the theft time; thus improve the time of early warning; adding theft cost makes some people abandon stealing this equipment, thus achieves antitheft object.
Accompanying drawing explanation
Fig. 1 is the utility model mounting structure schematic diagram, and Fig. 2 is the structural representation of gland nut 1, and Fig. 3 is the plan view of nut-protecting sleeve 2; Fig. 4 is the A direction view in Fig. 3, and Fig. 5 is the axonometric drawing of locking nut 4, and Fig. 6 is the structural representation of screw 8; reference character and corresponding name are called: gland nut 1; nut-protecting sleeve 2, pin 3, locking nut 4; presser feet 5; gap 6, joint 7, screw 8.
Embodiment
As shown in Figure 1, model utility is a kind of anti-theft bolt, is made up of nut-protecting sleeve 2, locking nut 4, screw 8, and screw 8 is through joint 7, and the presser feet 5 on locking nut 4 is pressed in connection portion 7, and nut-protecting sleeve 2 covers locking nut 4; As shown in Figure 3, Figure 4, the cylindrical wall of nut-protecting sleeve 2 is at least provided with 3 semicircular pins 3, offering in the bottom of the cylinder of nut-protecting sleeve 2 can through the circular hole K of screw 8.
As shown in Figure 4, pin 3 adjacent angular of nut-protecting sleeve 2 is 120 degree.
As shown in Figure 5, be trapezoidal presser feet 5 at least 3 cross sections that are circumferentially provided with of one end of locking nut 4.
As shown in Figure 5, on locking nut 4 the adjacent angular of presser feet 5 be 120 degree.
The gland nut 1 of anti-theft bolt of the present utility model can take out after installation is complete.
As shown in Figure 1, anti-theft bolt of the present utility model, is made up of nut-protecting sleeve 2, locking nut 4, screw 8; Screw 8 is through joint 7, and the presser feet 5 on locking nut 4 is pressed on joint 7; Nut-protecting sleeve 2 covers locking nut 4, and one end of gland nut 1 is pressed on nut-protecting sleeve 2, and the pin 3 on nut-protecting sleeve 2 is combined closely with gap 6 thus locks, and takes out gland nut 1.
As shown in Fig. 1 ~ Fig. 6; installation process of the present utility model is; screw 8 is preferentially through the joint 7 that will fix; make the threaded end of screw 8 move to maximum distance apart, screw in locking nut 4 and its presser feet 5 is combined closely with joint 7, put into nut-protecting sleeve 2 and make its pin 3 end preferentially enter screw 8; screw 8 is through circular hole K; pin 3 aligns with gap 6, screws in gland nut 1 and makes it be pressed in until pin 3 enters completely from gap 6 on nut-protecting sleeve 2, take out gland nut 1 installation.
