Technical Field

[0001] The utility model belongs to the technical field of thermal insulation boards, and in particular relates to a soft thermal insulation board for a refrigerated truck. Background Art

[0002] In the existing Chinese patent database, a patent entitled "A foam sponge insulation board that is easy to splice" is disclosed, with application number CN202321451672.5 and application date 2023-06-08. The device includes a first insulation board, a second insulation board, a first connecting board and a second connecting board. The first insulation board and the second insulation board are provided with a first connecting board and a second connecting board on opposite sides respectively. The first connecting board and the second connecting board are fixedly connected to the corresponding first insulation board and the second insulation board. The first connecting board is provided with a mounting groove inside, and the end and side of the first connecting board are provided with a plug hole and a side hole connected to the inside of the mounting groove respectively. The side of the second connecting board is fixedly installed with a first plug block, and the first plug block is slidably inserted into the inside of the mounting groove from the side hole. The plug hole is slidably inserted with a second plug block, and a hook is provided on one side of the first plug block, and a slot is provided on one side of the second plug block. When installing, the new type only needs to insert the first connecting board and the second connecting board into the mounting groove through the first plug block to complete the plugging, and then insert the second plug block into the plug hole of the first connecting board. It has a small structure and is easy to produce.

[0003] During the installation process, most of the existing insulation boards are fixed by fixing parts, which are troublesome to disassemble and difficult to reuse after disassembly and assembly, and the cost of use is high. Therefore, this article aims to propose a soft insulation board for refrigerated trucks, which is easy to disassemble and can be reused on different vehicles. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing insulation panels are mostly fixed by fixing parts during the installation process, which is troublesome to disassemble and difficult to reuse after disassembly and assembly, and the cost of use is high. In order to improve its shortcomings, the utility model provides a soft insulation panel for a refrigerated truck.

[0005] In order to achieve the above object, the utility model is realized by the following technical solutions:

[0006] A soft heat-insulating plate for a refrigerated truck comprises a block-shaped sponge core, the outer surface of the sponge core is wrapped with PVC cloth, both sides of the PVC cloth are connected to external sponges, the surface of the external sponge is provided with a burr surface, and the bottom of the sponge core is provided with a U-shaped reinforcement piece, the inner surface of an ear plate section of the reinforcement piece is connected to one side surface of the bottom of the sponge core, and the inner surface of the other ear plate section of the reinforcement piece is connected to the other side surface of the bottom of the sponge core.

[0007] Compared with the prior art, the beneficial effects of the utility model are: the overall weight of the device is lighter, the installation and disassembly is convenient, and it can be reused on different vehicles after disassembly, the thermal insulation effect is good, the setting of the reinforcement makes the entire insulation board more integrated, and plays a certain role in bottom waterproofing. The device is suitable for industrial production and has strong practicality.

[0008] As a preferred solution, the reinforcement is fixed in the sponge core via bolts.

[0009] As a preferred solution, the external sponge is bonded to the side of the PVC cloth via double-sided adhesive.

[0010] As a preferred solution, a handle is provided on the side of the sponge core body, which facilitates installation and removal of the insulation board and provides a force point.

[0011] As a preferred embodiment, the sponge core is a hard foam sponge. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a structural schematic diagram of the utility model.

[0013] Figure 2 for Figure 1 Cross-sectional view at AA in the middle.

[0014] In the figure: 1 sponge core, 2 PVC cloth, 3 external sponge, 4 burr surface, 5 reinforcement, 6 bolts,

[0015] 7 handles. DETAILED DESCRIPTION

[0016] The technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 1-2 As shown, a soft heat insulation board for a refrigerated truck includes a block-shaped sponge core 1, the outer surface of the sponge core 1 is wrapped with a PVC cloth 2, both sides of the PVC cloth 2 are connected with external sponges 3, the surface of the external sponge 3 is provided with a burr surface 4, and the bottom of the sponge core 1 is provided with a U-shaped reinforcement 5, the inner surface of one ear plate section of the reinforcement 5 is connected to one side of the bottom of the sponge core 1, and the inner surface of the other ear plate section of the reinforcement 5 is connected to the other side of the bottom of the sponge core 1. The reinforcement 5 is fixed in the sponge core 1 by bolts 6. The external sponge 3 is bonded to the side of the PVC cloth 2 by double-sided tape. A handle 7 is provided on the side of the sponge core 1. The setting of the handle 7 facilitates the installation and disassembly of the insulation board and provides a force point. The sponge core 1 is a hard foam sponge.

[0018] During installation, the operator clamps the external sponge 3 along the inner side of the frame of the rear door of the refrigerated truck into the frame, so that the external sponge 3 is in close contact with the surrounding frames of the rear door of the refrigerated truck. At the same time, the burred surface 4 on the external sponge 3 can enable the insulation boards to be connected to each other to form a larger whole board. During disassembly, the insulation board can be pulled out of the frame through the handle 7, which is convenient for reuse on different vehicles.

[0019] The present utility model is not limited to the above-mentioned embodiments. On the basis of the technical solution disclosed in the present utility model, technicians in this field can make some substitutions and deformations to some technical features therein according to the disclosed technical content without creative labor, and these substitutions and deformations are all within the protection scope of the present utility model.
