Abstract
The utility model relates to a theftproof fastener, which solves the problem that outdoor installation components are easy to steal under the condition of unmanned attendance. The utility model is characterized in that the utility model is provided with a screw bolt (1) which is provided with a neck replaces a hexagonal screw bolt and screw nut connection pair through the tight screwing of an end surface wrenching and screwing body type screw nut (2), and plays the action of clamping fasteners and connected components. The screw bolt which is matched with a special hole spacer (6) plays the action of preventing the owned screw bolt body from rotating, and a rotatable protection ring (3) which is matched with the wrenching and screwing body type screw nut, (2) prevents the component from rotating and loosing, and plays the theftproof action of the component is provided.
Description
The utility model belongs to the outdoor member of mechanical type and connects fastener, is specifically related to a kind of anti-theft fastening piece.
At present, multiple member all adopts the bolt and nut auxiliary connection to connect in connection is fastening.This kind method is installed very easily out of doors and is stolen by the people, if adopt the antitheft mode of destroying rib-loop, not only to maintenance or change and to be connected member and to bring inconvenience, can not reuse, and behind the destruction rib-loop, reduced the load-bearing capacity that bolt, nut auxiliary connection connect, it connects fastening reliability and has also reduced.
The purpose of this utility model provides a kind of common tool and can't dismantle, and has antitheft characteristics, and is recyclable multiplexing, do not reduce the anti-theft fastening piece of fastening performance again.
Version of the present utility model is, makes band neck bolts (1) and end face and removes and twist after body formula nut (2) screws, and plays the connecting elements effect, cooperated the effect that prevents that the body of bolt itself from rotating with profile hole pad (6).It is to play the role of fastening after screwing with band neck bolt (1) that end face is removed stubborn body (2), and has cooperated antitheft effect with rotatable guard collar (3).
Adopt the utility model to compare with hex bolts fastening means commonly used, has following advantage: 1, use the fastening outdoor facilities of this securing member, need not destroy screw thread, tightness is strong, and the fastening screw thread that will destroy of outdoor use bolt and nut, promptly reduce the fastening performance of bolt and nut, can not reuse again, also increased the expense and the trouble of maintenance.2, use this securing member safe and reliable, do not have specific purpose tool can't steal facility, theftproof performance is good.3, this securing member can be reused, and is easy to maintenance, and the auxiliary connection that especially is useful for outdoor member connects engineering, has reduced use cost.
Detailed structure of the present utility model is provided by accompanying drawing or embodiment
Accompanying drawing 1
(1) is band neck bolt
(2) remove stubborn carrying or nut for end face
(3) be rotatable guard collar
(4) or (5) for being connected object
(6) be easy shape hole sheet
The utility model is a kind of rotating guard collar of body formula nut that utilizes end face to remove to twist, and band neck bolt is with after the profile hole sheet cooperates, the novel anti-theft securing member of replacement hex bolts, nut auxiliary connection.
Embodiment is at first to be with neck bolt (1) and easy shape hole pad (6) to be assembled together, after will being connected member (5) or (4) and aligning, band neck bolt (1) the profile hole pad (6) that insertion assembles, end face being removed stubborn body formula nut (2) is assembled together with rotatable guard collar (3) again, be screwed on the band neck bolt (1), be screwed onto to be adjacent to hand and be connected member (4) or (5), be screwed onto with specific purpose tool and need use torque.Because of removing to twist on formula nut (2) and the hexagonal nut profile commonly used very big difference (being cone shape) is arranged during dismounting, thereby want to remove with worker commonly used is loosening that to twist formula nut (2) be extremely impossible, and rotatable guard collar (3) blindage is arranged, play the antitheft effect of outdoor member.
Claims (1)
- Its feature of a kind of anti-theft fastening piece is removed by band neck bolt (1), end face and is twisted body formula nut (2), guard collar (3), profile hole pad (6) and form, described band neck bolt (1) and profile hole pad (6) combination, end face tightens that formula nut (2) is end face structure, cone shape cooperates composition with guard collar (3), and guard collar (3) is rotatable.
