Description

The Rear Door structure of refrigerated vehicle carriage

Technical field

The utility model belongs to refrigerator car technical field, in particular to a kind of Rear Door structure of refrigerated vehicle carriage.

Background technique

Refrigerator car is the closed transport van for transport frozen or fresh-keeping cargo, is usually used in transport frozen food Product, dairy produce, vegetable and fruit, vaccine drug etc..

The back door of traditional refrigerated vehicle carriage is that a hollow door-plate is first arranged, then using the foam filled door-plate of AB glue 3mm medium-density plate and color steel plate are finally pasted in hollow part inside and outside door-plate, and limit the overall thickness of rear door plate It is made as 68mm, meets the requirement for installing adhesive tape on subsequent technique.

But the Rear Door structure of above-mentioned traditional refrigerated vehicle carriage there is a problem of it is following: in traditional handicraft, above-mentioned knot Structure will use skeleton 1 ' to be fixed, complex manufacturing technology, and heat insulation effect is poor.

Therefore, it is simple that a kind of structure can how be provided, saving member, and the good refrigerated vehicle carriage of heat insulation effect Back door structure, becoming those skilled in the art has technical problem to be solved.

Utility model content

In view of the above shortcomings of the prior art, the technical problem to be solved by the utility model is to how to provide a kind of knot Structure is simple, saving member, and the back door structure of the good refrigerated vehicle carriage of heat insulation effect.

In order to solve the above-mentioned technical problem, the utility model uses the following technical solution:

A kind of Rear Door structure of refrigerated vehicle carriage, including symmetrical two Rear Doors being vertically arranged, the Rear Door For layer structure, which is characterized in that layered structure is adhered to the high density by a high-density foam plate layer and two The leading flank of foam sheet and the PVC board layer of trailing flank are constituted.

In this way, the utility model directly uses high-density foam plate layer and two PVC board layer bondings, relative to traditional work Skill has the advantages that following: 1. without being fabricated to hollow rear filling AB glue foaming for Rear Door, and manufacture craft is simpler；2. need not It is additionally welded and fixed using skeleton, saves component；3. the saturating warm nature energy that high-density foam plate layer foams relative to AB glue More preferably, make that condensation will not occur between two PVC board layers, further enhance the thermal insulation property of Rear Door；4. can be straight The thickness for connecing adjustment PVC board layer and high-density foam plate layer, allows the overall thickness of Rear Door to be more easily set as 68mm, full The requirement of adhesive tape is installed on sufficient subsequent technique.

Further, the PVC board layer with a thickness of 15mm, the high-density foam plate layer with a thickness of 38mm.

In this way, the thickness distribution of PVC board layer and high-density foam plate layer is more reasonable, guaranteeing stable structure, heat insulating ability While can be good, also make the overall thickness 68mm of Rear Door, meets the requirement for installing adhesive tape on subsequent technique.

Further, the Rear Door is provided with column, the Rear Door on the side of Rear Door described in another It is provided with lock in the middle part of the PVC board layer surface of rear side, the PVC board layer surface upper and lower part on rear side of the Rear Door It is provided with hinge, is additionally provided on the PVC board layer on rear side of the Rear Door to install the column, hinge and the peace of lock Fill hole.

In this way, being convenient to assemble column, hinge and lock on Rear Door.

It further, further include horizontally disposed stiffening plate, the stiffening plate is covered on outside the mounting hole, with closing The opening of the mounting hole.

In this way, stiffening plate enhances the structural strength of Rear Door.

It further, further include self-tapping screw, the self-tapping screw passes through and fixes the stiffening plate and the PVC board Layer.

In this way, being fixed using self-tapping screw, convenient for assembly and disassembly.

Further, the stiffening plate with a thickness of 5mm.

In this way, the enough self-tapping screws of the thickness of 5mm carry out guaranteeing a preferable enhancing Rear Door structure across fixation While effect, the weight of itself is not increased additionally also.

It further, further include built-in fitting, the rear table of the PVC board layer on front side of the built-in fitting and the Rear Door Face is fixedly connected by horizontal bolt, and one end of the bolt is placed in the PVC board layer, and the other end extends to described pre-buried Part is outer can connect with the high-density foam plate layer.

In this way, built-in fitting and PVC board layer are bolted to connection as an entirety, be more convenient subsequent PVC board layer and The connection of high-density foam plate layer.

Further, the Rear Door is inclined outwardly and is vertically arranged oblique for a front end close to the side of the column Face.

In this way, more convenient be sealed the side of Rear Door.
