Abstract

The invention of resisting collision protection thick stick belongs to the security timber wood area, it is mainly used to produce automobile bumper, road partition wall, solve damnifying the bumper because of the pursuing tail and the bruising of car body because of scrape the partition wall: the invention is a complex construction of steel and rubber-plastics or hard rubber, it has steel support(1), and it has a protect body which is stretch (2); or it is produced by rubber-plastics material or hard rubber material; the benefit is: when it is used to automobile bumper, if the pursuing tail collision occurred in middle or low speed, the bumper can give some elasticity, increase the buffering power, in order to reduce or avoid the bumper damnification; when it is used to the road partition wall, it can decrease or avoid the bruising of car body because of the scratch.

Description

Crash-resistant protects thick stick

Technical field

The invention belongs to safety and use the material field, relate to a kind of crash-resistant and protect thick stick.

Background technology

Along with rolling up of automobile, rear crash event takes place in the vital communication lines in city often, and vehicle rear-end collision much all takes place under middle low speed, and impaired then at first is the front and back bumper/spoiler of vehicle; In now, the bumper/spoiler of automobile all is that inelastic metallic material or hard plastics are made, in case knock into the back, very easily sustains damage; In addition, most highway barrier or divider wall all are that metallic material is made, in case automobile scratches, great majority all can cause hard defects to vehicle body.

Summary of the invention

The technical matters that solves: provide a kind of crash-resistant to protect thick stick, can overcome the deficiencies in the prior art, be used to manufacture Federal bumper, highway barrier or divider wall, can increase cushion effect, thereby the problem of damage bumper/spoiler in the time of can alleviating or avoid to knock into the back under the especially middle low speed of rear-end collision, and automobile scratch divider wall causes the problem of vehicle body hard defects.

The technical scheme that adopts:

Crash-resistant protects thick stick, it is characterized in that: be composite structured, have the supporter of steel, supporter compound rubber and plastic or hard rubber material constitute and certain elastomeric watch box arranged; Perhaps constitute by having certain elastomeric rubber-plastics material or hard rubber material fully.

Beneficial effect: crash-resistant protects thick stick, owing to have certain elasticity, be collided and produce certain screen resilience, be used to manufacture Federal bumper, highway barrier or divider wall, can increase cushion effect, thereby can alleviate or avoid rear-end collision especially in low speed when knocking into the back, the damage that causes to bumper/spoiler, and the hard defects that cause to vehicle body of automobile scratch divider wall.

The specific embodiment

Further explanation in detail in conjunction with the accompanying drawings;

As shown in Figure 1, in supporter 1 is encapsulated in by watch box 2 fully, and once-combined moulding is manufactured and is formed.

As shown in Figure 2, be the part encapsulated type, supporter 1 exposes a part along protecting the thick stick axis, and once-combined moulding is manufactured and formed.

As shown in Figure 3, composite structured for machinery, supporter 1 tightens together by being connected locking piece 3 mutually with watch box 2; Shown in figure (a), watch box 2 is whole continous way, and perhaps shown in figure (b), watch box 2 is a breakaway-element.

The thick stick that protects of the present invention by having certain elastomeric rubber-plastics material or hard rubber material when constituting, all adopts once moulding method to manufacture when fully.

Thick stick linearly type or the flexure type of protecting of the present invention, its cross-sectional plane is a flush type for oval, circular or a side, relative opposite side is a curved face type.

The thick stick that protects of the present invention has the supporting mechanism that is connected and fixed according to needs at corresponding position, so that be fixed together with corresponding object, and helps changing.

Claims

1, crash-resistant protects thick stick, it is characterized in that: be composite structured, have the supporter (1) of steel, supporter (1) compound rubber and plastic or hard rubber material constitute and certain elastomeric watch box (2) arranged; Perhaps constitute by having certain elastomeric rubber-plastics material or hard rubber material fully.

2, crash-resistant according to claim 1 protects thick stick, it is characterized in that: supporter (1) perhaps is the part encapsulated type in being encapsulated in by watch box (2) fully, and supporter (1) exposes a part along protecting the thick stick axis.
