Abstract
The utility model discloses a penetration-preventing fence for an automobile. The penetration-preventing fence comprises a net body and a fixed supporting part, wherein the net body is formed by fixedly connecting a plurality of crisscrossed steel beams; the fixed supporting part comprises a plurality of lifting arms; the lifting arms are perpendicularly fixed with the upper part of the net body; and a plurality of supporting rods are connected between the lifting arms and the net body. The penetration-preventing fence for the automobile adopts a net structure, and disperses and absorbs a collision action force when the automobile collides into the penetration-preventing fence, so that the damage degree caused by the accident is reduced.
Description
Technical field
The utility model relates to a kind of airhandling equipment, especially a kind ofly draws the equipment that extraneous air focuses on back decentralized supply fresh air in the environment for use.
Background technology
In vehicle travels, the back vehicle is often because the safety distance and cause the generation of traffic rear-end collision of failing to remain valid, if front truck is high capacity waggon, back car is dilly such as miniature car and motor bike etc., because the front truck car weight is bigger, when then the car speed of a motor vehicle is very fast, the possibility that back car gets into when rear-end collision takes place bottom the front truck is very big, in this case, dilly serious damage can occur and grievous injury or the dead major traffic accidents that therefore chaufeur causes often occur.Also have, if roadlice and truck side bumped during vehicle travelled, can cause fuel tank and the brake system of lorry to be damaged, cause fire or brake failure, roadlice continues to move ahead after creeping into the lorry side more even, and the truck trailing wheel is pressed onto on the roadlice, will cause the rollover of two cars, leads to the tragedy of car crash.For avoiding above-mentioned accident, can crashproof support be installed at tailstock bottom and the car side bottom of lorry, but just simply be welded with several angle bar, its bulk strength is lower, even take place also can produce distortion after the slight impact, can not play crashproof effect at all.
Summary of the invention
The purpose of this utility model provides the anti-drilling hurdle of a kind of automobile, adopts net structure, will collide application force and disperse to absorb when vehicle and the collision of anti-drilling hurdle, and the damage degree that accident is caused reduces.
The utility model is to realize above-mentioned purpose like this:
The anti-drilling hurdle of automobile, comprise that net body and fixed support portion are grouped into, described net body is formed by fixedly connecting by many crisscross girder steels, the fixed support portion branch comprises many arms, arm is fixed with the upper vertical of net body respectively, also is connected with many strut bars between arm and the net body.
Wherein, described strut bar is hound, and the one end is captiveed joint with net body, and the other end is captiveed joint with arm.
Wherein, described many strut bars form a plurality of bearing surfaces, each bearing surface is made up of a plurality of L type strut bars and a hound, captive joint with arm and net body respectively in L type strut bar two ends, hound one end is in arm or net body captive joint, and the other end is captiveed joint with the turn end of a plurality of L type strut bars.
Wherein, the girder steel of described net body is the hollow circular steel pipe.
Wherein, horizontal girder steel bottom is high-intensity main girder steel, and other horizontal girder steels are secondary girder steel.
The beneficial effects of the utility model are: because the net body on anti-drilling hurdle is to adopt crisscross girder steel to form net structure, when dilly and high capacity waggon bump, the application force actv. that net body can produce collision disperses, and reduces the damage degree of vehicle.And whole net body is connected with car body by many strut bars, can improve integrally-built intensity, more effectively prevents net body flexural deformation at the bottom of the car, thereby dilly pierces the possibility of lorry bottom when reducing collision.Girder steel is to adopt the manufacturing of hollow circular steel pipe in addition, and when bumping, hollow circular steel pipe itself is collapsible, absorption collision energy that can be a large amount of.Also have, horizontal girder steel bottom adopts high-intensity steel manufacturing, as the main girder steel of whole net body, because the intensity of main girder steel is higher, can bear bigger impact force, can dilly be stopped actv., prevents that it from piercing the high capacity waggon bottom.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is the block diagram of first kind of embodiment of the utility model;
Fig. 2 is the block diagram of second kind of embodiment of the utility model.
The specific embodiment
With reference to Fig. 1, the anti-drilling hurdle of automobile, comprise net body 1 and fixed pedestal part 2 compositions, described net body 1 is formed by fixedly connecting by many crisscross girder steels 11, fixed pedestal part 2 comprises many arms 21, arm 21 is fixed with the upper vertical of net body 1 respectively, also is connected with many strut bars 22 between arm 21 and the net body 1.Because the net body 1 on anti-drilling hurdle is to adopt crisscross girder steel 11 to form net structure, when dilly (as minibus or motor bike) and high capacity waggon bump, the application force actv. that net body 1 can produce collision disperses, and reduces the damage degree of vehicle.And whole net body 1 is connected with car body by many strut bars 22, can improve integrally-built intensity, more effectively prevents net body 1 flexural deformation at the bottom of the car, thereby dilly pierces the possibility of lorry bottom when reducing collision.
The girder steel 11 of described net body 1 is the hollow circular steel pipe, and when bumping, hollow circular steel pipe itself is collapsible, absorption collision energy that can be a large amount of.
Wherein, horizontal girder steel 11 bottom is high-intensity main girder steel, and other horizontal girder steels 11 are secondary girder steel.As the main girder steel of whole net body 1, because the intensity of main girder steel is higher, can bear bigger impact force, can dilly be stopped actv., prevent that it from piercing the high capacity waggon bottom.The number on anti-drilling hurdle is installed at lorry decides according to the size on lorry and anti-drilling hurdle, the general tailstock is installed one just, and each side of vehicle then can be installed more than one.
