Bolt need to be matched by head and screw rod (having externally threaded cylindrical body) a kind of fastener dimerous with nut It closes, for being fastenedly connected two parts for having through-hole.This type of attachment claims to be bolted.As nut is revolved from bolt Under, and the two parts can be made to separate, therefore being bolted is to belong to be detachably connected.
Bolt is divided into common bolt by the force way of connection and has the bolt of articulation hole.Common bolt is mainly held Axial stress is carried, it can also be with not high lateral stressed of bearing requirements.The bolt of articulation hole will be used in the dimensional fits in hole When by cross force.
Bolt is divided by head shape turret head, round end, square spigot, countersunk head etc..Wherein turret head is It is most common.General countersunk head, which is used in, requires the connection smooth place for not having protrusion of rear surface, because countersunk head may be screwed in part.Circle Head can also be screwed into part.The screwing force of square toes can more greatly, but size is very big.There are also the dedicated stud of welding, one Head has screw thread, can be welded on part, the direct nutting in another side.
Field is set up at present steel tower, metal frame, senior executive's guardrail etc. are tampered in order to prevent, generally use antitheft spiral shell Bolt, the general naked leakage in head of existing anti-theft bolt (antitheft using the unidirectional groove of multiple groups) outside, are easy to lead with contacting rain water Cause is got rusty, and screw rod is easy to loosen, for this purpose, we have proposed a kind of anti-theft bolts of loosing-proof rust-proof to come into operation, on solving State problem.
Utility model content
The purpose of this utility model is to provide it is a kind of can loosing-proof rust-proof anti-theft bolt, to solve in above-mentioned background technique The problem of proposition.
To achieve the above object, the utility model provides the following technical solutions: it is a kind of can loosing-proof rust-proof anti-theft bolt, packet Protection shell is included, the bottom of the protection shell is fixed with elastic extruding plate, and the inner cavity of the protection shell is equipped with bolt head, The bottom of the bolt head is fixed with plectane, and the lower section of the plectane is equipped with stripper plate, solid between the plectane and stripper plate Surely it is equipped with spring, the top of the spring and low side are fixedly connected at the top of plectane bottom and stripper plate respectively, the extruding The bottom of plate is fixed with elastomeric pad, the lower section screw rod of the elastomeric pad, the top of the screw rod through elastomeric pad and Stripper plate simultaneously extends to the top of stripper plate and is fixedly connected with the bottom of plectane, and the spring is socketed on stripper plate, the spiral shell Bolt head is equipped with tightens mouth, and the internal chamber wall of the tightens mouth is equipped with unidirectional tooth.
Preferably, the bolt head is up-narrow and down-wide formula conical structure.
Preferably, the tightens mouth is circle, and the unidirectional tooth is evenly arranged on the inner wall of tightens mouth.
Preferably, the center point of the stripper plate, which is equipped with, penetrates hole, and is greater than the diameter of screw rod through the diameter in hole.
Preferably, the inner cavity of the protection shell is equipped with internal screw thread, and the annular outer wall of the stripper plate is equipped with and interior spiral shell The compatible external screw thread of line.
Compared with prior art, the utility model has the beneficial effects that this bolt is during bolt is tightened, elastic cushion Sector-meeting contacts to form extruding with fixed object surface, with screw rod screw in Object Depth lengthening, will so that elastomeric pad backward Movement, compressed spring, so that this bolt has good anti-loosening effect, being equipped with includes protection shell, when bolt is fixed, spiral shell Bar is located inside fixated body, and bolt head and stripper plate are located at the outside of fixated body, by protection shell and squeezes Plate is fixed, and the part of the naked leakage of bolt outside is protected, avoidable and contacting rain water, preventing bolt from getting rusty influences fixed effect Fruit, protect shell screw direction and bolt to screw direction identical, be equipped with elastic extruding plate, the fixation for protecting shell can be reinforced Effect.
Detailed description of the invention
Fig. 1 is the utility model section figure;
Fig. 2 is the utility model bolt head top view;
Fig. 3 is the utility model bolt front view.
In figure: 1 bolt head, 2 plectanes, 3 protection shells, 4 elastomeric pads, 5 screw rods, 6 stripper plates, 7 springs, 8 tightens mouths, 9 Unidirectional tooth, 10 elastic extruding plates.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 1-3, the utility model provides a kind of technical solution: it is a kind of can loosing-proof rust-proof anti-theft bolt, including Shell 3 is protected, the bottom of the protection shell 3 is fixed with elastic extruding plate 10, and the inner cavity of the protection shell 3 is equipped with bolt First 1, the bottom of the bolt head 1 is fixed with plectane 2, and the lower section of the plectane 2 is equipped with stripper plate 6, the plectane 2 and extruding Spring 7 is fixed between plate 6, the top of the top of the spring 7 and low side respectively with 2 bottom of plectane and stripper plate 6 is fixed Connection, the bottom of the stripper plate 6 are fixed with elastomeric pad 4, the lower section screw rod 5 of the elastomeric pad 4, the screw rod 5 Top is through elastomeric pad 4 and stripper plate 6 and extends to the top of stripper plate 6 and is fixedly connected with the bottom of plectane 2, the spring 7 are socketed on stripper plate 6, and the bolt head 1 is equipped with tightens mouth 8, and the internal chamber wall of the tightens mouth 8 is equipped with unidirectional tooth 9.
