Abstract
The utility model discloses a dedicated theft-proof bolt connecting piece for traffic equipment and traffic sign boards, which comprises a theft-proof nut, a bolt corresponding to the theft-proof nut and a U-shaped connecting groove with a sinking tube; wherein, the screw cap of the bolt is square, and is glidingly matched with the inside of the U-shaped connecting groove. When using the utility model, connect the back side of the U-shaped connecting groove with the connected piece (for example, a traffic sign board) by welding or making the two as a whole, put the screw cap into the U-shaped connecting groove, put the screw through a second connected piece (for example, the post of the sign board) and then fix the screw with the nut. Since the screw cap is fixed with the U-shaped connecting groove and can not turn, only dedicated tools are needed to revolve the nut when assembly and disassembly; the operation is very convenient.
Description
Technical field
The utility model relates to a kind of connector, specifically is the special-purpose anti-theft bolt connector of a kind of traffic route facility and sign board, be mainly used in traffic route facility and sign board and the bar of fixing them or be connected.
Background technology
Existing traffic route facility and sign board are that common screw bolt and nut is easy to often cause losing of facility and sign board with the general tool dismounting with adopting common screw bolt and nut, its shortcoming being connected of the bar of fixing them and seat.I disclose a kind of " anti-theft bolt and nut " in the utility model patent of patent No. ZL02285884.9, principal character is that the outer rim of this nut and nut is circular, adopts common instrument it can not to be dismantled, and reaches antitheft purpose.But also having deficiency, is exactly will block nut and nut simultaneously with special tool when mounted, operates very inconvenient.
Summary of the invention
The purpose of this utility model just provides a kind of traffic route facility and the special-purpose anti-theft bolt connector of sign board, to solve the problem of existing anti-theft nut and bolt inconvenient operation when loading and unloading.
The technical solution of the utility model is: comprise circular anti-theft nut, the bolt that cooperates with this anti-theft nut, reducing U-shaped link slot, the nut of this bolt is rectangle (comprising square), cooperates with the slides within of described U-shaped link slot.
When using the utility model, the back side of U-shaped link slot is connected with connected piece (as sign board), can adopts welding or be structure as a whole, in screw cap imbedded U-shaped link slot with connected piece, screw rod passes another connected piece (as the vertical rod of sign board), uses nut fastening then.Because nut is not blocked and can rotate by the U-shaped link slot,, made things convenient for many so when loading and unloading, only need get final product with special tool turn anti-theft nut.
Description of drawings
Fig. 1 is the axial structural representation of the utility model screw bolt and nut;
Fig. 2 is the right view of Fig. 1;
Fig. 3 is the sectional view of the utility model when using.
The specific embodiment
Referring to Fig. 1～Fig. 3, the utility model comprises circular anti-theft nut 3, the bolt that cooperates with anti-theft nut 3, reducing U-shaped link slot 5, and the nut 1 of described bolt is a square (also rectangle), cooperates with the slides within of described U-shaped link slot 5.When using the utility model, the back side of U-shaped link slot 5 is connected with connected piece 4 (as sign board), can adopt and weld or integrative-structure.When connecting nut 1 is inserted in the U-shaped link slot 5, screw rod 2 passes another connected piece 6 (as the vertical rod of sign board), uses anti-theft nut 3 fastening then.Because nut 1 is not blocked and can rotate by U-shaped link slot 5, so only need get final product with special tool turn nut 3 when loading and unloading, operation is very easy.
