Abstract

The utility model relates to a head cover plate, in particular to a head cover plate used for the top of products such as refrigerator, disinfector. The head cover plate comprises a metal main board and a plastic skirt edge. The main board with holes or pits arranged at fringe thereof is embedded into the skirt edge whose plastic is filled in the holes or pits at fringe of the main board, thus to make the main board and the skirt edge firmly connected. The main board is high in strength and low in cost.

Description

A kind of lamina tecti

The utility model relates to a kind of lamina tecti, particularly a kind of lamina tecti that is used for refrigerator, disinfection cupboard.

At present, various household electrical appliance kinds are tired many, and China's per-capita housing is also lower, make that many families are be in placed in the middle putting and worried of various household electrical appliance, what some people can stack stacks as far as possible, but, concerning high refrigerator of popularity rate and disinfection cabinet, be plastics mostly because of its top cover, its intensity is not high, if it will be very dangerous that products such as electric cooker, micro-wave oven are placed its top, though if the lamina tecti of products such as refrigerator-disinfection cabinet can be increased with metal manufacturing intensity, its production cost will rise, and influence the competitiveness of product in market.

The purpose of this utility model refrigerator that cost is low with regard to providing a kind of intensity height, the lamina tecti that disinfection cabinet is used.

The technical solution of the utility model is:

A kind of lamina tecti comprises mainboard and limit skirt, it is characterized in that: be embedded with the limit skirt around the mainboard.

The described lamina tecti of above-mentioned utility model, it is characterized in that: mainboard is made with metal material, and the limit skirt is plastics; The part of mainboard built-in edges skirt has some holes allows the plastic edge skirt pass these holes when the embedding injection forming, reaches the purpose of firm connection and release local stress, and wherein the bore dia the closer to the edge is big more.

The described lamina tecti of above-mentioned utility model, its feature also is: mainboard is made with metal material, and limit skirt injection-moulding plastic, wherein the edge of mainboard built-in edges skirt is provided with pit and inserts in the pit when the embedding injection forming by the plastic edge skirt, and limit skirt and mainboard are connected firmly.

Owing to adopted technical scheme described in the utility model, the intensity of lamina tecti is big and production cost is low, and the plastics proportion descends greatly, and the product distortion is little, also helps environmental protection.

The explanation of accompanying drawing drawing:

Fig. 1 is the refrigerator structure stereogram of the utility model when being used for the refrigerator top cover plate.

Fig. 2 is the independent stereogram of lamina tecti among Fig. 1.

Fig. 3 and Fig. 5 are respectively mainboard marginal portion A-A cutaway view along Fig. 2 when being provided with hole and pit.

Fig. 4 is the vertical view of mainboard among Fig. 3.

Be further described below in conjunction with accompanying drawing.

In conjunction with the accompanying drawings 1, Fig. 2, Fig. 3 and Fig. 4 as can be seen, the lamina tecti 1 that is positioned at refrigerator body 2 tops is made up of metal mainboard 4 and plastic edge skirt 3; Wherein mainboard 4 setting-ins are gone in the limit skirt 3, the part of mainboard 4 built-in edges skirts 3 (being the edge) has wherein keep to the side the more Kong Yueda of edge of some holes (5 and 6), to discharge the local stress of limit skirt 3, the limit skirt 3 that with plastics is material is in process of injection molding, and its plastics are filled directly into the hole (5 and 6) at mainboard 4 edges.

Fig. 5 is that limit skirt 3 plastics in process of injection molding of plastics are filled directly into pit 7 as can be seen equally, and mainboard 4 is combined firmly with limit skirt 3.

Certainly the also direct method of injection moulding setting-in of the method for attachment of metal mainboard 4 and plastic edge skirt 3; With screw that it is fixing with mainboard 4 as independent injection mo(u)lding limit skirt 3 back, also the method for available riveted joint is fixed, and also can be in advance the metal mainboard 4 at center be installed to the casing top, and after the filled heat insulation layer, installation limit skirt is not done to state at this more in the casing.
