The 3rd, the type guide rail is not considered fool proof, and installation personnel anti-situation occurs adorning easily when assembling, and installation personnel must be confirmed the front and back of guide rail earlier, can install, and occurs setup error easily for some installation personnels of lacking experience.
The utility model content
At the defective that exists in the prior art, the purpose of this utility model is to provide a kind of panel beating guide rail of communication equipment, turn over setting in the bending edges of fixing hole place, can not take unnecessary space, evade securing member the device on the machine dish PCB is produced interference, the utility model guide rail is formed by two identical rail guide piece left-hand threads of structure in addition, therefore there is not the anti-problem of adorning, need not consider the fool proof design, need not reduce fixing hole quantity simultaneously, the fastness that keeps the panel beating guide rail to install.
For reaching above purpose, the technical scheme that the utility model is taked is: a kind of panel beating guide rail of communication equipment, the rail guide piece that comprises the strip that two structures are identical, the middle part of each described rail guide piece has base portion, a side of described rail guide piece is the bending edges that vertical base portion is provided with, described base portion two ends are provided with ventilation slot, ventilation slot forms guide-track groove away from a side and another side of rail guide piece adjacent thereto of bending edges, one end and the base portion side of described rail guide piece are respectively equipped with L shaped connecting pin, connecting pin is positioned at the relative side of bending edges, the end that described rail guide piece does not have connecting pin is the plane of structure plate that vertical base portion is provided with, also be provided with fixed head between the ventilation slot of described plane of structure plate and vicinity, be equipped with an assembly hole on described fixed head and the base portion, described connecting pin end is equipped with an installing hole.
On the basis of technique scheme, the connecting pin of described base portion side and the assembly hole on the matrix are not located along the same line.
On the basis of technique scheme, described two rail guide piece centers symmetry fastens and is provided with, and two bending edges are positioned at the same side and are oppositely arranged.
On the basis of technique scheme, described bending edges is provided with a plurality of fixing holes.
On the basis of technique scheme, a side of described plane of structure plate is provided with conductive fabric.
The beneficial effects of the utility model are: described panel beating guide rail is fastened by two rail guide pieces and is provided with, and its bending edge homonymy is relative, is contained in the inboard behind the fastening, can not take too much position, is fit to use in the cramped construction equipment; Two rail guide piece structures are identical simultaneously, do not have the fool proof problem of installation, install simple and convenient; Bending edges is installed after the securing member, can not produce the device on the machine dish PCB and interfere, and need not reduce fixing hole quantity simultaneously, the fastness that keeps the panel beating guide rail to install.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 3 and Figure 4, the panel beating guide rail of the utility model communication equipment comprises the rail guide piece of the strip that two structures are identical, the middle part of each rail guide piece all has base portion 1, and a side of described rail guide piece is the bending edge 2 that vertical base portion 1 is provided with, and bending edges 2 is provided with a plurality of fixing holes 21.The two ends of described base portion 1 also are respectively equipped with ventilation slot 3, ventilation slot 3 forms guide-track groove 4 away from a side of bending edges 2 and another side of rail guide piece adjacent thereto, one end of described base portion 1 side and rail guide piece is equipped with L shaped connecting pin 5, described connecting pin 5 is positioned at the relative side of described bending edge 2, and described connecting pin 5 ends are parallel to plane, base portion 1 place.The end that described rail guide piece does not have connecting pin 5 is the plane of structure plate 6 that vertical base portion 1 bending is provided with, also be provided with fixed head 7 between the ventilation slot 3 of described plane of structure plate 6 and vicinity, described plane of structure plate 6 also is parallel to base portion 1 extension and is provided with mounting panel 11, and mounting panel 11 is provided with through hole 12.The end of described L shaped connecting pin 5 is provided with installing hole 51, is equipped with assembly hole 8 on described fixed head 7 and the base portion 1, and the assembly hole 8 on the connecting pin 5 of base portion 1 side and the base portion 1 is not on same straight line.The end that described rail guide piece does not have fixed head 7 is provided with assembled plate 9, and assembled plate 9 is provided with conjugate foramen 10.
