Abstract

The utility model relates to a glass guard bar of a rearview mirror on a lorry squab panel, which is a strip sheet-metal component, wherein the sheet-metal component is formed by punching a strip sheet; both ends of the sheet-metal component are provided with flattening parts (11) with mounting holes; the sheet-metal component is bent in the same circular measure towards the same side at positions close to the flattening parts (11) of both ends, so that the whole sheet-metal component is in a shape of an arrow bow. The glass guard bar has the advantages that: the manufacturing is simple; and the whole surface of the glass guard bar can be subjected to surface treatment effectively, so that the service life of the glass guard bar is increased.

Description

Truck cab rear view window glass guard bar

Technical field

The utility model relates to a kind of attached selectable unit (SU) on the lorry, particularly truck cab rear view window glass guard bar.

Background technology

Usually be separated by with rear end panel between truck cab and the loading space, as shown in Figure 1, on the rear view window 2 of rear end panel 1 glass be installed, glass guard bar 3 is installed on the rear view window 2, directly clash into glass and cause viteous fracture to prevent the goods in the loading space.At present, this glass guard bar is that the steel pipe two ends are flattened and bending, bore fixed orifice at the flat position at steel pipe two ends, be installed on the rear end panel 1 this glass guard bar made from steel pipe thus, when carrying out surface treatments such as phosphatization, steel duct can not be handled, and rainwater easily enters and stockpiles therein from glass guard bar upper end, causes the glass guard bar easily from the corrosion gradually of socket inside, especially the lower end corrosion of glass guard bar is fast especially, has reduced its service life.

The utility model content

It is simple that problem to be solved in the utility model just provides a kind of processing and manufacturing, the truck cab rear view window glass guard bar of long service life.

Technical problem to be solved in the utility model is to realize by such technical scheme, it is a strip shape plate work piece, this plate work piece is to form through punching press with strip shape sheet material, the two ends of plate work piece are the evener that is provided with mounting hole, plate work piece is bending with radian ground to the same side near evener place, two ends, and it is arc to make whole plate work piece form arrow.

Because the utility model adopted the strip shape plate work piece, it is easy to make processing, simultaneously when carrying out surface treatment such as phosphatization, can both effectively handle everywhere, not being blocked forms the surface-treated dead angle, thereby prevents corrosion, increases the service life of truck cab rear view window glass guard bar.

Owing to adopted technique scheme, the advantage that the utlity model has is: make processing simply, increased the service life of truck cab rear view window glass guard bar.

Description of drawings

Description of drawings of the present utility model is as follows:

Fig. 1 installs and uses scheme drawing for the truck cab rear view window glass guard bar of background technology;

Fig. 2 is a front view of the present utility model;

Fig. 3 is a birds-eye view of the present utility model;

Fig. 4 is the A-A cut away view of Fig. 2.

Among the figure: 1. rear end panel; 2. rear view window; 3. glass guard bar; 11. evener; 12. fixed orifice; 13. reinforced rib.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

As Fig. 2, shown in Figure 3, the utility model is the strip shape plate work piece, described plate work piece is to form through punching press with strip shape sheet material, the two ends of plate work piece are the eveners 11 that is provided with mounting hole 12, plate work piece is bending with radian ground to the same side near evener 11 places, two ends, and it is arc to make whole plate work piece form arrow.

The utility model is the strip shape sheet metal, when carrying out surface treatments such as phosphatization, can both effectively handle everywhere, can increase the service life of glass guard bar.

As Fig. 2, shown in Figure 4, the further spirogyrate of the direction that arches upward of the plate work piece whole plate work piece of middle mind-set along its length becomes reinforced rib 13, the effect of reinforced rib 13 is the intensity that increases the glass guard bar, makes it to bear the more large impact power from goods, avoids the damage of rear view window glass.

The advantage that the utlity model has is: make processing simply, surface treatment can both effectively be carried out everywhere in its surface, has increased its service life.

Claims (2)
