Description
Technical field
The utility model belongs to automobile steel sheet technical field, relates to a kind of coating-plating enclosed load compartment back door steel plate particularly.
Background technology
Coating steel plate refers to and carries out coating modification to surface of steel plate, by degrease, recrystallization annealing, coating-plating and subsequent treatment process, obtains high strength, corrosion resistant steel plate.Coating steel plate has lightweight, attractive in appearance and good Corrosion Protection, provide a kind of novel raw material to building industry, shipbuilding industry, Rail car manufacture industry, furniture industry, electric utility etc., serve with the good result such as steel generation wood, efficient construction, economize energy, preventing pollution.
Van is called van again, is mainly used in the various article of hermetically sealed transport, and the van of Special Category can also transporting chemical dangerous goods, because it has maneuverability, the advantage that easy to operate, freight volume is large and be subject to extensive use.The multiplex steel plate assembling of carriage back door of existing van is made, but the intensity of existing back door steel plate is lower, easily impaired, distortion when causing being hit; In addition, existing back door steel plate exists when assembling with side steel plate and is connected imprecise problem, easily makes extraneous air enter in compartment.
Summary of the invention
The utility model is to solve the problems of the technologies described above, and provides a kind of intensity high and connect closely reliable coating-plating enclosed load compartment back door steel plate.
The technical solution of the utility model is: a kind of coating-plating enclosed load compartment back door steel plate, comprise coating-plating steel plate body, described coating-plating steel plate body comprises the substrate be made up of boiling steel or killed steel, the outside of substrate is provided with honeycomb layer and coated layer successively, coating-plating steel plate body is in " L " type, coating-plating steel plate body comprises bending connecting portion and support portion, the outer surface of bending connecting portion is provided with at least one projection be made up of rubber, the middle part of support portion is provided with plug housing, support portion is provided with radial convex tendon centered by plug housing, four edges of support portion are provided with latticed convex tendon.
Preferably, described radial convex tendon is be arranged symmetrically with up and down centered by the horizontal center line of plug housing.
Preferably, described plug housing is welded on coating-plating steel plate body.
Closer, the quantity of described projection is four.
Preferably, described radial convex tendon and coating-plating steel plate body are made into integration.
Preferably, described latticed convex tendon and coating-plating steel plate body are made into integration.
The beneficial effects of the utility model are: first, by selecting boiling steel or killed steel as substrate, honeycomb layer and coated layer is set gradually in the outside of substrate, its mechanical property can not only be improved, ensure that substrate does not ftracture, coating does not depart from, coating steel plate can also be made to have excellent high temperature resistant, atmospheric corrosion resistance, anti-oxidant and electrochemical protection performance, improve the service life of carriage back door steel plate;
Secondly, steel plate body design is become to comprise the L-type of bending connecting portion, can conveniently with the assembling of side steel plate, projection on multiple differing heights directions of being made up of rubber is set simultaneously on bending connecting portion, multi-sealed effect can be played, guarantee to connect closely reliable, avoid extraneous air to enter in compartment;
Finally, the support portion of steel plate body arranges radial convex tendon centered by plug housing, latticed convex tendon is set at the edge of steel plate body, local strengthening can be carried out to steel plate upper stress concentrated position, thus the intensity of whole steel plate can be improved, be damaged after avoiding being hit and be out of shape.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional schematic diagram of the present utility model.
In figure, 1, coating-plating steel plate body, 2, plug housing, 3, radial convex tendon, 4, latticed convex tendon, 5, substrate, 6, honeycomb layer, 7, coated layer, 8, bending connecting portion, 9, protruding, 10, support portion.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in detail.
As depicted in figs. 1 and 2; a kind of coating-plating enclosed load compartment back door of the present utility model steel plate; comprise coating-plating steel plate body 1; particularly; compound color coated steel sheet body 1 comprises the substrate 5 be made up of boiling steel or killed steel, is provided with the honeycomb layer 6 that can improve its intensity and the coated layer 10 that can improve its chemoproection performance in the outside of substrate 5 successively.Select boiling steel or killed steel as substrate; honeycomb layer and coated layer is set gradually in the outside of substrate; its mechanical property can not only be improved; ensure that substrate does not ftracture, coating does not depart from; coating steel plate can also be made to have excellent high temperature resistant, atmospheric corrosion resistance, anti-oxidant and electrochemical protection performance, improve the service life of carriage back door steel plate.
Coating-plating steel plate body 1 comprises bending connecting portion 8 and support portion 10, and its monnolithic case, in " L " type, is provided with at the outer surface of bending connecting portion 8 projection 9 be made up of rubber that four are positioned at differing heights position.Adopt rubber to make protruding, when back door steel plate is connected with side steel plate, because extruding force can make it deform to rubber convex role, and then fit tightly on back door steel plate and side steel plate, guarantee that it connects closely reliable, avoid extraneous air to enter in compartment.
The middle part of support portion 10 is welded with the plug housing 2 for switch back door, and support portion 10 is provided with radial convex tendon 3 centered by plug housing 2, and four edges of support portion 10 are provided with latticed convex tendon 4.Particularly, radial convex tendon 3 is in being arranged symmetrically with up and down centered by the horizontal center line of plug housing 2, and radial convex tendon 3 and latticed convex tendon 4 are all made into integration with coating-plating steel plate body 1.The benefit that two diverse locations arrange two kinds of multi-form reinforcement convex tendons on support portion is, for different concentrated stresses, can arrange different reinforcement version, can improve the intensity of whole steel plate, is damaged and is out of shape after avoiding being hit.
Although the foregoing describe detailed description of the invention of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these change and amendment all falls into protection domain of the present utility model.
