Abstract

The utility model discloses a guardrail theftproof bolt assembly, including the bolt body, bolt body top sets up the mushroom head, and the hole is seted up to the upper end of mushroom head, downtheholely sets up four wedges, and adjacent wedge is 90 and sets up on the horizontal plane for the bolt body can only unidirectional rotating, screw thread in the double -screw bolt portion thread coupling nut of bolt body, nut is reverse screw thread. The texture of this practicality in the nut passes through the tapping of cross screwdriver for the bolt body is with clockwise wrong income nut, screw up fixed, but can the clockwise rotation construction bolt, reverse then because of there being the slope, make the cross screwdriver put forth effort, thereby unable dismantlement reaches the theftproof purpose.

Description

A kind of guardrail anti-theft bolt component

Technical field

The utility model relates to a kind of anti-theft bolt component, specifically a kind of guardrail anti-theft bolt component.

Background technique

Existing guardrail bolt assembly parts are many, it is complicated to install, and be easily disassembled, public guardrail facility is easily stolen, existing rail bolt assembly at least have four and more than.

Model utility content

The purpose of this utility model is to provide a kind of guardrail anti-theft bolt component, to solve the problem proposed in above-mentioned background technology.

For achieving the above object, the utility model provides following technological scheme:

A kind of guardrail anti-theft bolt component, comprise bolt body, bolt body top arranges mushroom head, and hole is offered in the upper end of mushroom head, arranges four wedge-shaped blockss in hole, and adjacent wedge-shaped blocks, in the horizontal plane in 90 ° of settings, makes bolt body can only one-way rotation; The shaft of described bolt body is threaded nut, and the screw thread in nut is reverse thread.

As further program of the utility model: arrange fixed plate between the mushroom head of bolt body and nut.

As the utility model further scheme: one end end face contacted with fixed plate of nut arranges projection, and fixed plate is offered the hole corresponding with convex shape.

Compared with prior art, the beneficial effects of the utility model are: form theft-prevention structure by bolt body, nut, fixed plate three part, nut is placed in railing inside, the shape of the hole on fixed plate and nut side projection matches, fixed plate is sleeved on nut high spot, plays the effect that hold-doun nut is adjacent to railing.Texture in nut, by cross screwdriver tapping, makes bolt body to be screwed into nut clockwise, tightens fixing, but can turn clockwise construction bolt, reversing then because there being the gradient, cross screwdriver cannot be puted forth effort, thus cannot dismantle, reaching antitheft object.

Accompanying drawing explanation

Fig. 1 is the structural representation of bolt body.

Fig. 2 is the structure plan view of bolt body.

Fig. 3 is the mounting structure figure of bolt body, nut and fixed plate.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

Refer to Fig. 1 ~ 3, in the utility model embodiment, a kind of guardrail anti-theft bolt component, comprise bolt body 1, bolt body 1 top arranges mushroom head 3, and hole 2 is offered in the upper end of mushroom head 3, arranges four wedge-shaped blockss 4 in hole 2, adjacent wedge-shaped blocks 4, in the horizontal plane in 90 ° of settings, makes bolt body 1 can only one-way rotation;

The shaft of described bolt body 1 is threaded nut 5, and the screw thread in nut 5 is reverse thread, thus the construction bolt that can turn clockwise, reversing then because there being the gradient, cross screwdriver tapping cannot be puted forth effort, thus cannot dismantle.

Between the mushroom head 3 of bolt body 1 and nut 5, fixed plate 6 is set, one end end face contacted of nut 5 is arranged protruding 8, and fixed plate 6 is offered the hole 7 corresponding with protruding 8 shapes, thus prevent fixed plate 6 from rotating with fixed plate 6.

This practicality is made up of bolt body 1, nut 5, fixed plate 6 three part, nut 5 is placed in railing inside, outside hole on fixed plate 67 and nut 5, the shape of protruding 8 matches, and fixed plate 6 is sleeved on protruding 8 places of nut 5, plays the effect that hold-doun nut 5 is adjacent to railing.Texture in nut 5 by cross screwdriver tapping, then by bolt body 1 to be screwed into nut 5 clockwise, is tightened fixing, but can turn clockwise construction bolt, reversing then because there being the gradient, cross screwdriver cannot be puted forth effort, thus cannot dismantle, reaching antitheft object.

To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any reference character in claim should be considered as the claim involved by limiting.

In addition, be to be understood that, although this specification is described according to mode of execution, but not each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technological scheme in each embodiment also through appropriately combined, can form other mode of executions that it will be appreciated by those skilled in the art that.
