Abstract
The utility model discloses a plastic cover plate used for a filter and a tower mounted amplifier. The plastic cover plate comprises a cover plate body. Reinforcing ribs are arranged on an interior surface of the cover plate body. The cover plate body is an injection-molded piece. The cover plate body is molded by plastic through injection molding, so that costs of the cover plate is lowered and the cover plate is light. Meanwhile, the additionally-arranged reinforcing ribs help to guarantee strength of the cover plate body. The plastic cover plate is suitable for the filter and the tower mounted amplifier.
Description
Technical field
The utility model relates to the waterproofing protection parts of communicating by letter of putting for filter and tower, specifically a kind of plastic cover plate of putting for filter and tower.
Background technology
Before the utility model proposes, the cover plate major part that filter and tower are produced in letting pass already forms by aluminum profile extrusion or magnesium alloy pressure-casting.But because the aluminium cover plate is by the Tool in Milling moulding, thus the serious waste of material not only caused easily, and also the efficient of making is low, tool damage is serious, has greatly increased manufacturing cost.And magnesium alloy pressure-casting generally adopts die casting to form, although efficient is higher, the market price of magnesium alloy is comparatively expensive, has increased manufacturing cost and finished weight is larger.
The utility model content
The purpose of this utility model is the deficiency that exists in order to solve the above-mentioned background technology, propose a kind of lightweight, cost is low and simple in structure is used for the plastic cover plate that filter and tower are put.
The utility model adopts following technical scheme for achieving the above object: a kind of plastic cover plate of putting for filter and tower, comprise cover board body, and described cover board body inner surface is provided with reinforcement, described Cover Plate Body Is moulding.By adopting the described cover board body of injection molding, reduced cost and lightweight, simultaneously, the reinforcement that adds has guaranteed the intensity of cover board body.
In such scheme, described cover board body outer surface is arcuate structure, is convenient to like this cover board body demoulding, certainly also can be designed to other structures.
In such scheme, the both sides of described arcuate structure are respectively equipped with chamfering.Because the thickness of arcuate structure both sides is excessive, is unfavorable for moulding, so by adopting the mode of design chamfering, the thickness of small arcuate structure both sides is convenient to moulding.
In such scheme, described cover board body and reinforcement are monolithic construction.
The utility model by adopting the described cover board body of injection molding, has reduced cost and lightweight on the one hand; On the other hand, the reinforcement that adds has guaranteed the intensity of cover board body; On the one hand, this external surface of plate is designed to arcuate structure again, is conducive to the cover board body demoulding; At last, add respectively chamfering in the both sides of arcuate structure, be conducive to moulding.
In sum, the utlity model has lightweight, cost is low and the characteristics such as simple in structure.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Description of drawings
Fig. 1 is the main TV structure schematic diagram of present embodiment;
Fig. 2 is the sectional structure schematic diagram along A-A line among Fig. 1.
In the drawings, cover board body 1, reinforcement 2, arcuate structure 3, chamfering 4.
Embodiment
Embodiment: a kind of plastic cover plate of putting for filter and tower as shown in Figure 1, comprise cover board body 1, described cover board body 1 inner surface is provided with reinforcement 2, and described cover board body 1 is moulding.By adopting the described cover board body 1 of injection molding, reduced cost and lightweight, simultaneously, the reinforcement 2 that adds has guaranteed the intensity of cover board body 1.
Above-mentioned cover board body 1 outer surface is arcuate structure 3, is convenient to like this cover board body 1 demoulding.The both sides of described arcuate structure 3 are respectively equipped with chamfering 4.Because the thickness of arcuate structure 3 both sides is excessive, is unfavorable for moulding, so by adopting the mode of design chamfering 4, the thickness of small arcuate structure 3 both sides is convenient to moulding.Described cover board body 1 and reinforcement 2 adopt integrated injection forming.Described reinforcement 2 can be netted or honeycomb coaly.
The utility model has reduced cost and lightweight by adopting the described cover board body 1 of injection molding; The reinforcement 2 that adds has guaranteed the intensity of cover board body 1; Plate body 1 outer surface is designed to arcuate structure 3, is conducive to cover board body 1 demoulding; Both sides at arcuate structure 3 add respectively chamfering 4, are conducive to moulding.
Below only be preferred embodiment of the present utility model, in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
