Abstract
The utility model relates to a shielding cylinder of anti-interference equipment. The shielding cylinder includes a first shielding cylinder body, a second shielding cylinder body, a third shielding cylinder body, a fourth shielding cylinder body, a fifth shielding cylinder body and a sixth shielding cylinder body which are arranged from top to bottom; the fracture surface of the first shielding cylinder body is arc-shaped; the lower end of the first shielding cylinder body is welded with the upper end of the second shielding cylinder body; the lower end of the third shielding cylinder body is welded with the upper end of the fourth shielding cylinder body; the lower end of the fifth shielding cylinder body is welded with the upper end of the sixth shielding cylinder body; the second shielding cylinder body and the third shielding cylinder body are in a conjoined structure; and the fourth shielding cylinder body and the fifth shielding cylinder body are in a conjoined structure. According to the shielding cylinder of the utility model, based on the improvement of molds, five welding gaps in the prior art can be decreased to three welding gaps at present, and at the same time, the treatment performed on the welding gaps is decreased, and as a result, an R arc position of a product is not prone to deformation, the size of the product can be ensured better, and production capacity can be improved, and production cost and labor intensity of workers can be reduced.
Description
Technical field
The utility model relates to the structure of the shielding cylinder of anti-tampering equipment.
Background technology
The effect of shielding cylinder be with shielding cylinder with component, circuit, sub-assembly, the interference source of cable or whole system is surrounded, and prevents that interfere with electromagnetic field is to outdiffusion; Or with shielding cylinder with receiving circuit, equipment or system are surrounded, and prevent that they are subjected to the influence of external electromagnetic field.Existing shielding cylinder comprises first shielding cylinder, secondary shielding cylindrical shell, the 3rd shielding cylinder, the 4th shielding cylinder, the 5th shielding cylinder and the 6th shielding cylinder that sets gradually from top to bottom, neighbouring two shielding cylinders adopt welding, form five road weld seams, the per pass commissure need be polished, make inefficiency, and increased production cost and working strength of workers.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, to provide a kind of weld seam few shielding cylinder.
The purpose of this utility model is achieved in that shielding cylinder, comprise first shielding cylinder, secondary shielding cylindrical shell, the 3rd shielding cylinder, the 4th shielding cylinder, the 5th shielding cylinder and the 6th shielding cylinder that set gradually from top to bottom, the section of first shielding cylinder is curved, the upper end section of secondary shielding cylindrical shell is curved, the section of the 5th shielding cylinder is curved, and the section of the 6th shielding cylinder is curved; The upper end welding of the lower end of described first shielding cylinder and secondary shielding cylindrical shell, the upper end welding of the lower end of the 3rd shielding cylinder and the 4th shielding cylinder, the upper end welding of the lower end of the 5th shielding cylinder and the 6th shielding cylinder, described secondary shielding cylindrical shell and the 3rd shielding cylinder disjunctor arrange, and the 4th shielding cylinder and the 5th shielding cylinder disjunctor arrange.
The improvement of the utility model by mould makes secondary shielding cylindrical shell and the 3rd shielding cylinder disjunctor setting, the 4th shielding cylinder and the 5th shielding cylinder disjunctor arrange, weld seam was reduced to three present road weld seams by five former road weld seams, reduced the processing of commissure simultaneously, product R arc place is not yielding, size more can guarantee, has also improved production capacity, reduces production costs and working strength of workers.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
As shown in Figure 1, be shielding cylinder, comprise first shielding cylinder 1, secondary shielding cylindrical shell 2, the 3rd shielding cylinder 3, the 4th shielding cylinder 4, the 5th shielding cylinder 5 and the 6th shielding cylinder 6 that set gradually from top to bottom, the section of first shielding cylinder 1 is curved, the upper end section of secondary shielding cylindrical shell 2 is curved, the section of the 5th shielding cylinder 5 is curved, and the section of the 6th shielding cylinder 6 is curved.The upper end welding of the lower end of first shielding cylinder 1 and secondary shielding cylindrical shell 2, secondary shielding cylindrical shell 2 and the 3 disjunctor settings of the 3rd shielding cylinder, the upper end welding of the lower end of the 3rd shielding cylinder 3 and the 4th shielding cylinder 4, the 4th shielding cylinder 4 and the 5 disjunctor settings of the 5th shielding cylinder, the upper end welding of the lower end of the 5th shielding cylinder 5 and the 6th shielding cylinder 6.
