Drawings
FIG. 1 is a side view of a bridge having electromagnetic shielding functionality;
FIG. 2 is an enlarged view of a portion of FIG. 1;
fig. 3 is a structural schematic diagram of a part of the structure in the bridge frame with the electromagnetic shielding function.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Fig. 1 to fig. 3 are a side view and a partial enlarged view of a bridge 1 with an electromagnetic shielding function according to the present invention, and fig. 3 is a schematic structural view of the bridge with a cover plate 3 and an upper shielding plate 5 removed. The bridge frame 1 with the electromagnetic shielding function comprises a groove body 2, a cover plate 3, a lower shielding plate 4 and an upper shielding plate 5.
The tank body 2 is a deep-tank structure formed by processing an aluminum plate, seven mounting holes are respectively arranged at two ends of the tank body in the length direction, the number of the bottom surfaces is three, two mounting holes are respectively arranged on two side walls, and seven mounting holes are arranged at positions slightly close to the right side (under the view angle of fig. 3) in the middle part. The edges of the two sides are turned over outwards, and a convex strip 21 is processed and used for being connected with the cover plate 3.
The cover plate 3 is a shallow groove structure processed by an aluminum plate, the two side edges of the cover plate are bent outwards, and a groove 31 is processed. The groove 31 abuts against the top of the groove body 2 on one hand, and is connected with the raised line 21 arranged on the groove body 2 on the other hand. The upper shielding plate 5 is a steel screen plate, is laid on the inner wall of the cover plate 3 and is fixedly connected with the cover plate.
The lower shielding plate 4 comprises a solid steel belt and steel screen plates arranged on two sides of the steel belt, wherein the structure of the solid part is similar to that of the groove body 2 and is laid on the inner wall of the groove body 2, the screen plate part extends to two sides along the length direction of the groove body 2, and the whole length is equal to half of the length of the groove body 2. The solid part is also symmetrically provided with two groups of seven mounting holes in the same arrangement as the mounting holes arranged on the tank body 2.
In specific implementation, a plurality of bridges 1 with electromagnetic shielding function need to be connected end to form a channel for installing cables. Each of the tank bodies 2 is provided with one lower shielding plate 4, and a mounting hole arranged in the middle of the tank body 2 is aligned with a group of mounting holes on the right side (under the view angle of fig. 3) of the lower shielding plate 4 and is connected with the same through bolts. And one lower shielding plate 4 is also arranged between two adjacent groove bodies 2, and mounting holes arranged at the two ends of the groove bodies 2 are respectively aligned with the two groups of mounting holes of the lower shielding plates 4 and are connected by bolts.
Since the length of the lower shield plate 4 is the same as that of the tank body 2, this arrangement just fills the inner wall of the tank body 2. In fig. 3, in order to show the structure of the tank body, the lower shielding plate 4 provided at the head and tail ends of the tank body 2 is cut off, and only half of the lower shielding plate is shown.
After the splicing is completed and the cable is arranged, the cover plate 3 is directly fixed with the upper shielding plate 5 and is buckled on the groove body 2, and the raised strips 21 are fixedly connected with the grooves 31. After the fixing, the edges of the upper shield plate 5 of the lower shield plate 4 abut.
The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes made by the present specification can be changed, or directly or indirectly applied to other related technical fields, and all the same principles are included in the protection scope of the present invention.
