Description

Technical Field

[0001] This utility model relates to the field of refrigerators, and in particular to a refrigerator door cover mounting structure. Background Technology

[0002] An important component of a frost-free refrigerator is the air vent that connects the refrigerator compartment and the freezer compartment, and the air vents located within the air vent. An air vent cover needs to be installed on top of the air vent to protect it and also serve a decorative purpose. Currently, the air vents are directly bolted to the inner wall of the refrigerator liner. This method requires workers to perform several bolt fixing operations, which increases the workload and makes the bolts prone to falling off after prolonged use. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide a simple and easy-to-install damper cover installation structure.

[0004] The technical solution adopted by this utility model to solve the problem is: a refrigerator door cover mounting structure, comprising:

[0005] The refrigerator liner has an air vent at the bottom and an inwardly recessed locking groove on the rear side.

[0006] An electric damper, wherein the electric damper is arranged within a damper hole;

[0007] The damper cover includes a main cover body and an insertion ring disposed at the bottom of the main cover body. A ventilation hole is formed in the insertion ring, which extends to the upper surface of the main cover body. An elastic locking member with elasticity is disposed on the rear side of the main cover body and is used to be embedded in the locking groove. The insertion ring is movably inserted into the damper hole.

[0008] When the elastic engaging member is embedded in the engaging groove, the top surface of the elastic engaging member faces the top surface of the engaging groove, and the top of the elastic engaging member is either gapped or overfitted with the top surface of the engaging groove.

[0009] As a further improvement to the above technical solution, the damper hole includes a wide hole at the top and a narrow hole at the bottom of the wide hole. A lower shell cover is inserted into the wide hole. A shell cavity is provided at the top of the lower shell cover. A through hole is provided at the bottom of the shell cavity, extending to the bottom of the lower shell cover. An embedded ring plate is provided at the bottom of the lower shell cover, inserted into the narrow hole and surrounding the through hole. The inner wall of the shell cavity is flush with the inner wall of the ventilation hole.

[0010] As a further improvement to the above technical solution, the bottom of the left and right sides of the insertion ring is provided with downward protruding insertion ends, and the left and right side walls of the lower shell cover are provided with insertion notches for the insertion ends to be inserted therein.

[0011] As a further improvement to the above technical solution, the length of the plug-in end gradually decreases from top to bottom.

[0012] As a further improvement to the above technical solution, the cavity is provided with an annular edge that surrounds the perforation and protrudes upward.

[0013] As a further improvement to the above technical solution, the lower end of the locking groove extends to the outer periphery of the damper hole.

[0014] As a further improvement to the above technical solution, the elastic engaging member is arc-shaped, and the bottom surface of the engaging groove is also arc-shaped. When the elastic engaging member is embedded in the engaging groove, the inner end face of the elastic engaging member completely abuts against the bottom surface of the engaging groove.

[0015] As a further improvement to the above technical solution, the elastic engaging component is plate-shaped.

[0016] The beneficial effects of this utility model are as follows: During installation, insert the plug ring at the bottom of the damper cover into the damper hole and push it back. At this time, the elastic locking component will first adhere to the inner wall of the refrigerator liner and be located above the locking groove. Then, press the damper cover down forcefully so that the plug ring is fully inserted into the damper hole. At this time, the elastic locking component is flush with the locking groove in the height direction, and the elastic locking component is embedded in the locking groove and adheres to the inner wall of the locking groove under its own elasticity. At this time, the installation is completed. After installation, the top surface of the elastic locking component is directly facing the top surface of the locking groove, and the top of the elastic locking component is either gapped or over-fitted with the top surface of the locking groove. Therefore, it is not possible to directly remove the damper cover upwards because the top of the elastic locking component will be pressed against the top surface of the locking groove. If you want to remove the damper cover, you need to pry the elastic locking component outwards so that the top of the elastic locking component is disengaged from the locking groove before you can remove the damper cover. With this solution, the installation of the damper cover is more convenient and faster, and the installation effect is stable and not easy to fall off. Attached Figure Description

[0024] Reference Figures 1 to 2 A refrigerator door cover mounting structure, comprising:

[0025] The refrigerator inner liner 10 has an air vent 12 at its bottom and an inwardly recessed locking groove 11 on its rear side.

[0026] An electric damper is arranged inside the damper hole 12;

[0027] The damper cover 20 includes a main cover body 21 and an insertion ring 22 disposed at the bottom of the main cover body 21. A ventilation hole 201 is formed in the insertion ring 22, which extends to the upper surface of the main cover body 21. An elastic locking member 23 is disposed on the rear side of the main cover body 21 and is used to be embedded in the locking groove 11. The insertion ring 22 is movably inserted into the damper hole 12.

[0028] When the elastic engaging member 23 is embedded in the engaging groove 11, the top surface of the elastic engaging member 23 faces the top surface of the engaging groove 11, and the top of the elastic engaging member 23 is either gapped or overfitted with the top surface of the engaging groove 11.

[0029] During installation, insert the insertion ring 22 at the bottom of the damper cover 20 into the damper hole 12 and push it back. At this time, the elastic locking member 23 will first adhere to the inner wall of the refrigerator inner liner 10 and be located above the locking groove 11. Then, press down the damper cover 20 forcefully so that the insertion ring 22 is fully inserted into the damper hole 12. At this time, the elastic locking member 23 is flush with the locking groove 11 in the height direction, and the elastic locking member 23 is embedded in the locking groove 11 and adheres to the inner wall of the locking groove 11 under its own elasticity. At this time, the installation is completed. After installation, the top surface of the elastic locking component 23 faces the top surface of the locking groove 11, and there is a gap or over-fit between the top of the elastic locking component 23 and the top surface of the locking groove 11. Therefore, it is impossible to directly remove the damper cover 20 upwards, because the top of the elastic locking component 23 will press against the top surface of the locking groove 11. To remove the damper cover 20, the elastic locking component 23 needs to be pried outwards so that its top disengages from the locking groove 11 before the damper cover 20 can be removed. With this solution, the installation of the damper cover 20 is more convenient and faster, and the installation effect is stable and not easy to fall off.

[0030] In this solution, the elastic engaging member 30 can be rod-shaped. Considering the need to increase the contact area between the elastic engaging member 30 and the inner wall of the engaging groove 11, it is preferable that the elastic engaging member 30 is plate-shaped.

[0031] Further optimization is preferred, where the damper hole 12 includes a wide hole portion 121 at the top and a narrow hole portion 122 at the bottom of the wide hole portion 121. A lower shell cover 30 is inserted into the wide hole portion 121. A shell cavity 31 is provided at the top of the lower shell cover 30. A through hole 32 extending to the bottom of the lower shell cover 30 is provided at the bottom of the lower shell cover 30. An embedded ring plate 33 is provided at the bottom of the lower shell cover 30, which is inserted into the narrow hole portion 122 and surrounds the outside of the through hole 32. The inner wall of the shell cavity 31 is flush with the inner wall of the ventilation hole 201. For easy positioning, the bottom of the left and right sides of the insertion ring 22 is preferably provided with downwardly protruding insertion ends 24. Insertion notches 35 are provided on the left and right side walls of the lower shell cover 30 for the insertion ends 24 to be inserted therein. Further optimization is preferred, where the length of the insertion ends 24 gradually decreases from top to bottom, thereby facilitating the insertion of the insertion ends 24 into the insertion notches 35.

[0032] Further optimization is preferred, with an annular edge 34 that surrounds the periphery of the perforation 32 and protrudes upwards, thereby preventing droplets from falling directly along the perforation 32.

[0033] Further optimization is preferred, with the lower end of the locking groove 11 extending to the outer periphery of the damper hole 12.

[0034] Further optimization is preferred, the elastic engaging member 23 is arc-shaped, and the bottom surface of the engaging groove 11 is also arc-shaped. When the elastic engaging member 23 is embedded in the engaging groove 11, the inner end face of the elastic engaging member 23 completely abuts against the bottom surface of the engaging groove 11, thereby making the overall structure lack stress concentration points and thus more stable.

[0035] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
