Description

Refrigerator heating pipe fixing structure and refrigerator Technical Field The application relates to the technical field of refrigerator manufacturing, in particular to a refrigerator heating pipe fixing structure and a refrigerator. Background The heating pipe is used as an important component of the defrosting system of the refrigerator, and the reliability and the production efficiency of the refrigerator can be directly affected by the stability and the convenience of installation of the heating pipe. The existing heating pipe is usually fixed by adopting a metal iron sheet structure, and the heating pipe is manually reset after being embedded by manually breaking off the iron sheet, so as to realize fixation. However, the fixing mode has low installation efficiency, the iron sheet is easy to generate plastic deformation in the repeated breaking and resetting processes, the iron sheet cannot be tightly fixed, the problems of offset, loosening, even falling off and the like of the installation position of the heating pipe possibly occur, the heat transfer effect and defrosting performance of the heating pipe are affected, and in the disassembling process, the iron sheet is required to be broken at the moment and limited by an operation space, the iron sheet or peripheral parts are easy to damage in the operation, and the maintenance cost and time are increased. Disclosure of utility model Accordingly, there is a need for a heating pipe fixing structure and a refrigerator which are free from plastic deformation, have high reliability, are more convenient to install, and can simplify the maintenance and replacement processes. In order to solve the technical problems, the application provides the following technical scheme: The refrigerator heating pipe fixing structure comprises a mounting plate and two elastic arms, wherein clamping holes with openings are formed in the side edges of the mounting plate, one elastic arm is arranged on each of two sides of each opening, the two elastic arms are connected with the mounting plate and surround the mounting plate to form a shrinkage opening, the shrinkage opening is communicated with the openings, and the caliber of the shrinkage opening is smaller than that of the openings; And the two elastic arms can move oppositely and elastically deform in response to the extrusion of the heating pipe, so that the necking is opened, and the heating pipe is clamped into the clamping hole through the opening. It can be understood that by arranging the mounting plate and the two elastic arms, the two elastic arms are respectively arranged on two sides of the opening of the clamping hole on the mounting plate and form a shrinkage opening communicated with the opening in a surrounding manner, when the heating pipe enters from the shrinkage opening, the two elastic arms are extruded by the heating pipe to elastically deform and move back to back so as to enable the shrinkage opening to open, and the heating pipe can be smoothly clamped into the clamping hole through the opening to realize fixation. Therefore, the two elastic arms can be automatically deformed in response to extrusion to enable the necking to be opened or reset, the fixing of the heating pipe is achieved, an operator is not required to manually break off and then manually reset in the fixing process, the operation is simpler and faster, the two elastic arms are elastically deformed in the process and can automatically reset, the heating pipe can be tightly fixed, the problems of offset, looseness, even falling and the like of the installation position of the heating pipe are avoided, meanwhile, when the heating pipe is detached, the heating pipe is pushed out to the necking position, the necking is automatically opened by the deformation of the elastic arms in response to extrusion, therefore, a fixing structure or peripheral components are not damaged, the easy detachment of the heating pipe is achieved, and the time and the cost of maintenance are saved. In one embodiment, an expansion section is arranged at one end of each elastic arm far away from the mounting plate, a flaring is formed between the two expansion sections, and the caliber of the flaring is larger than that of the necking. It can be understood that the expansion section that sets up has certain guide effect to the heating pipe, and the setting of flaring makes the alignment rate of heating pipe when inserting promote, has improved the efficiency of assembly, and when the heating pipe extrusion gets into the throat, expansion section can disperse the atress, avoids the elastic arm to excessively warp or fracture because of local stress is too big, has promoted the durability of structure. In one embodiment, the flaring is horn-shaped, and the horn-shaped flaring is provided with a small-caliber end and a large-caliber end which are oppositely arranged, and the small-caliber end is communicated with the necking. It can be understood that the sm
