Abstract
Description
Technical Field
[0001] The utility model relates to the field of composite skins, in particular to a firm glass fiber reinforced plastic skin. Background Art
[0002] With the rapid development of the communications industry, the demand for communications cabinets is increasing. Most traditional cabinets use steel sheet metal as the cabinet shell. During long-term use, the cabinet shell made of steel sheet metal will be affected by the external environment and corroded. Therefore, in order to make the cabinet shell made of steel sheet metal have good corrosion resistance, technicians compound a layer of fiberglass plate on the outside of the steel plate. The fiberglass plate and the steel plate are usually compounded with adhesives. Since the composite surfaces of traditional fiberglass plates and steel plates are smooth and flat surfaces, the composite firmness of the fiberglass plate and the steel plate in the later stage is poor and the adhesive is prone to overflow in large quantities during the composite process, which is not conducive to the high-quality production of fiberglass skins. Utility Model Content
[0003] In order to solve the above-mentioned problems, the utility model provides a strong fiberglass skin, including a fiberglass panel and a steel plate, the fiberglass panel is arranged on the upper end surface of the steel plate, a rectangular wire groove is arranged on the upper end surface of the steel plate near the outer edge, each side of the rectangular wire groove is provided with an elliptical notch, a plurality of circular holes are evenly opened on the upper end surface of the steel plate, annular grooves are arranged on the circular holes, wire grooves are arranged between each annular groove and are connected to each other through the wire grooves, and the circular hole passes through the upper surface and the lower surface of the steel plate.
[0004] Preferably, the rectangular wire groove, the annular groove and the wire groove are interconnected.
[0005] Preferably, the upper end surface of the steel plate is configured to be a rough matte surface.
[0006] Preferably, an adhesive is provided between the fiberglass reinforced plastic panel and the steel plate and the panel and the steel plate are laminated by the adhesive.
[0007] The beneficial effects of the utility model are as follows: the utility model has reasonable structural design, is easy to use, can make the composite between the glass fiber reinforced plastic panel and the steel plate more firm, and can also reduce the overflow of the adhesive between the glass fiber reinforced plastic panel and the steel plate during the composite process. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] The present invention will be described by way of examples with reference to the accompanying drawings, in which:

[0010] Figure 2It is a schematic diagram of the top view structure of the steel plate of the utility model;
[0011] Figure 3 It is a side view structural diagram of a circular hole of the utility model;
[0012] In the figure: 1. Fiberglass panel; 2. Steel plate; 3. Rectangular wire duct; 4. Oval notch; 5. Circular hole; 6. Annular groove; 7. Wire duct. DETAILED DESCRIPTION
[0013] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.
[0014] Any feature of this specification, unless otherwise specified, can be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise specified, each feature is only an example of a series of equivalent or similar features.
[0015] like Figure 1 , 2 A strong FRP skin as shown in 3 comprises a FRP panel 1 and a steel plate 2, wherein the FRP panel 1 is arranged on the upper end surface of the steel plate 2, a rectangular wire groove 3 is arranged on the upper end surface of the steel plate 2 near the outer edge, an elliptical notch 4 is arranged on each side of the rectangular wire groove 3, a plurality of circular holes 5 are evenly opened on the upper end surface of the steel plate 2, annular grooves 6 are arranged on the circular holes 5, wire grooves 7 are arranged between each annular groove 6 and are connected to each other through the wire grooves 7, and the circular holes 5 pass through the upper and lower surfaces of the steel plate 2.
[0016] The rectangular wire groove 3, the annular groove 6 and the wire groove 7 are connected to each other.
[0017] The upper end surface of the steel plate 2 is configured to be a rough matte surface.
[0018] An adhesive is provided between the fiberglass panel 1 and the steel plate 2 and the fiberglass panel 1 and the steel plate 2 are compounded by the adhesive.
[0019] During use, the circular holes 5 can divide a large bonding surface into small bonding surfaces when the FRP panel 1 and the steel plate 2 are compounded using a large amount of adhesive, thereby avoiding relative displacement between the FRP panel 1 and the steel plate 2 during compounding.
[0020] The arrangement of the rectangular wire groove 3, annular groove 6 and wire groove 7 can squeeze excess adhesive into the rectangular wire groove 3, annular groove 6 and wire groove 7 for circulation when the FRP panel 1 and the steel plate 2 are compounded, and by filling excess adhesive into the rectangular wire groove 3, annular groove 6 and wire groove 7, overflow of excess adhesive can be effectively reduced.
[0021] The oval notch 3 is provided to gather part of the adhesive flowing from the annular groove 6 and the wire groove 7 into the rectangular wire groove 3 to be filled in the oval notch 3, thereby further reducing the overflow of excess adhesive.
[0022] The upper end surface of the steel plate 2 is set to a rough rough surface, which can further avoid relative displacement when the FRP panel 1 and the steel plate 2 are composited, and can also improve the composite firmness of the FRP panel 1 and the panel 2.
[0023] The beneficial effects of the utility model are as follows: the utility model has reasonable structural design, is easy to use, can make the composite between the glass fiber reinforced plastic panel and the steel plate more firm, and can also reduce the overflow of the adhesive between the glass fiber reinforced plastic panel and the steel plate during the composite process.
