Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation, in particular to a novel thermal insulation structure. Background Art

[0002] Currently, most vending machines on the market have freezers that can keep food fresh to increase the shelf life of food. The freezers used in existing vending machines are generally composed of multiple insulation boards, and in order to improve the overall structural strength, most manufacturers will install a metal frame on the outside of the insulation board. In actual use, the inventor found that since the insulation board and the metal frame are directly fixed by screws, external heat will enter the freezer through multiple fixed screws, causing water droplets to easily form inside the freezer, which has an adverse effect on the insulation effect of the freezer and further increases the energy consumption of the freezer. Therefore, the utility model proposes a new insulation structure. Summary of the invention

[0003] The utility model provides a novel heat preservation structure to solve the problems mentioned in the above background technology.

[0004] The purpose of the utility model is achieved by the following methods:

[0005] A novel thermal insulation structure comprises a frame and an thermal insulation board, wherein the thermal insulation board is fixedly connected to the frame via a connecting assembly, wherein the connecting assembly comprises screws and a plastic limiter, wherein the plastic limiter is provided with a threaded hole for cooperating with the screw, and the screw is connected and cooperated with the threaded hole.

[0006] Furthermore, the plastic limiting component is composed of a main body and a limiting protrusion, and the limiting protrusion is integrally formed at one end of the main body.

[0007] Furthermore, the main body is arranged in a cylindrical shape.

[0008] Furthermore, the plastic limiting member passes through the frame and the insulation board, and the screw is in abutment with the frame or the insulation board.

[0009] Furthermore, the plastic limiting piece passes through the insulation board, and the screw passes through the frame to be connected and matched with the threaded hole, and is limitedly abutted against the frame.

[0010] The utility model improves the connection mode between the insulation board and the frame, and uses the cooperation of the plastic stopper and the screw to tightly connect the insulation board and the frame. At the same time, the design of the plastic stopper can also isolate the heat transfer from the screw, effectively preventing the external heat from entering the freezer through the screw, thereby improving the insulation effect of the freezer, reducing the energy consumption of the freezer, and thus greatly improving the insulation effect. In addition, the plastic stopper plays a buffering role to reduce the generation of friction, extend the service life of the insulation structure, and improve the practicality and convenience of the insulation structure.

[0016] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0017] Embodiment 1:

[0018] In this embodiment, Figure 1 As shown, a novel thermal insulation structure specifically implemented includes a frame 1 and a thermal insulation board 2. The thermal insulation board 2 is fixedly connected to the frame 1 through a connecting assembly. The connecting assembly includes a screw 3 and a plastic stopper 4. The plastic stopper 4 is provided with a threaded hole for matching with the screw 3. The screw 3 is connected and matched with the threaded hole. In this embodiment, the plastic stopper 4 passes through the thermal insulation board 2, and the screw 3 passes through the frame 1 to connect and match with the threaded hole, and is limitedly abutted against the frame 1.

[0019] Furthermore, the plastic limiting component 4 is composed of a main body 401 arranged in a cylindrical shape and a limiting protrusion 402 . The limiting protrusion 402 is integrally formed at one end of the main body 401 . The limiting protrusion 402 is used for limiting cooperation with the frame 1 or the insulation board 2 .

[0020] like Figure 2As shown, the insulation structure in this embodiment can be combined into a box body 5 when actually used, so as to be used in different scenarios, such as vending machines, freezers, etc. When used in combination, the insulation boards 2 of two adjacent insulation structures need to fit tightly, and the frame 1 is used to ensure the stability of the box body 5 after combination, and plays a role in shaping and fixing.

[0021] The utility model improves the connection mode between the insulation board 2 and the frame 1, and uses the cooperation of the plastic stopper 4 and the screw 3 to tightly connect the insulation board 2 and the frame 1. At the same time, the design of the plastic stopper 4 can also isolate the heat transfer from the screw 3, effectively preventing external heat from entering the freezer through the screw, thereby improving the insulation effect of the freezer, reducing the energy consumption of the freezer, and thus greatly improving the insulation effect. In addition, the plastic stopper 4 plays a buffering role to reduce the generation of friction, extend the service life of the insulation structure, and improve the practicality and convenience of the insulation structure.

[0022] Embodiment 2:

[0023] The difference between this embodiment and the first embodiment lies in the arrangement of the connection components, such as Figure 3-4 As shown, in this embodiment, the plastic limiter 4 passes through the frame 1 and the insulation board 2 , and the screw 3 is in abutment with the frame 1 or the insulation board 2 .
