Abstract

This utility model discloses an installation structure for a refrigerator main control board base box, including a refrigerator shell and a main control board base box. The refrigerator shell has mounting holes, and the main control board base box has a flange, a conduit, and a spring clip. During installation, the main control board base box is first tilted and the conduit is inserted into the inside of the refrigerator shell along the front side of the mounting hole. Then, the main control board base box is lowered. At this point, the guide slope at the bottom of the spring clip abuts against the outer edge of the rear side of the mounting hole, compressing the spring clip inward. This allows the end of the spring clip to pass from the outside of the refrigerator shell through the mounting hole to the inside of the refrigerator shell. The spring clip then resets, allowing its end to abut against the inner surface of the refrigerator shell. Simultaneously, the flange above the spring clip restricts further downward movement of the main control board base box, thus fixing the main control board base box to the refrigerator shell. This method allows for quick and convenient installation of the main control board base box, and it is also less prone to falling off, exhibiting strong stability.

Description

Technical Field

[0001] This utility model relates to the field of refrigerators, and in particular to an installation structure for the main control board bottom box of a refrigerator. Background Technology

[0002] A key component of a refrigerator is the main control board box and the main control board housed within it. To facilitate maintenance of the main control board, the main control board box is typically mounted directly on the outer surface of the refrigerator shell. It contains conduits connecting to the refrigerator shell, allowing electrical connections between internal components and the main control board. Currently, the main control board box is usually secured to the refrigerator shell using four sets of bolts and four sets of mounting holes. This method has two drawbacks: firstly, the need for four bolts increases production time; secondly, the traditional reliance on bolts for fixation necessitates tight tightening, and since the main control board box and the portion of the refrigerator shell where it's mounted are often not made of metal, workers frequently apply excessive force, causing cracks in the box or shell, making it impossible to secure the bolts. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide an installation structure for the main control board box of a refrigerator that is easy to install and has a low dependence on bolts.

[0004] The technical solution adopted by this utility model to solve the above problems is: an installation structure for the main control board bottom box of a refrigerator, comprising:

[0005] The refrigerator shell has mounting holes that extend through the inside and outside.

[0006] The main control board base box has a cavity. The outer periphery of the main control board base box has a flange. The front end of the main control board base box has a wire conduit located below the flange and extending outward. The wire conduit connects to the cavity. The rear side of the main control board base box has an elastic buckle located below the flange. The end of the elastic buckle extends upward and gradually tilts towards the outside of the main control board base box so that the bottom of the elastic buckle forms an inclined guide slope.

[0007] The main control board base box is installed into the mounting hole and the flange abuts against the outer surface of the refrigerator shell. The wire conduit is located at the lower end of the refrigerator shell. The elastic buckle can pass through the mounting hole from the outside of the refrigerator shell under the action of the guide slope, and the end of the elastic buckle can abut against the inner side of the refrigerator shell.

[0008] As a further improvement to the above technical solution, a set of mounting holes is provided on the flange, and a connecting hole is provided on the refrigerator shell that is opposite to the mounting hole. Positioning locking bolts are installed in the mounting hole and the connecting hole.

[0009] As a further improvement to the above technical solution, a connecting platform is provided on the flange on the same side as the conduit. A connecting cavity is provided on the connecting platform. An insertion hole communicating with the connecting cavity is provided on the outer side of the connecting platform. A grounding plug is provided on the edge of the mounting hole, facing the insertion hole. The grounding plug can be inserted into the connecting cavity along the insertion hole. The connecting hole is provided on the grounding plug, and the mounting hole is arranged on the bottom surface of the connecting cavity.

[0010] As a further improvement to the above technical solution, the mounting hole is provided with an internal thread that mates with the positioning bolt.

[0011] As a further improvement to the above technical solution, the edge of the mounting hole is provided with a mating notch that engages with the elastic buckle. The width of the mating notch is less than the length of the elastic buckle end deformed towards the outside of the main control board bottom box in its natural state.

[0012] As a further improvement to the above technical solution, the front end of the main control board box is provided with two wire conduits, which are evenly arranged on both sides of the front end of the main control board box.

[0013] As a further improvement to the above technical solution, a sealing gasket is provided between the flange and the outer surface of the refrigerator shell.

[0014] As a further improvement to the above technical solution, the two conduits are tilted toward the left and right sides of the main control board bottom box to form a diffuse shape, and the maximum distance between the two conduits is not greater than the maximum length of the mounting hole.

[0015] The beneficial effects of this utility model are as follows: During installation, the main control board base box is first placed at an angle and the wire tube is inserted into the inside of the refrigerator shell along the front side of the mounting hole. During this process, the flange is located on the outer surface of the refrigerator shell, so that the wire tube and the flange above the wire tube clamp a part of the refrigerator shell at the front edge of the mounting hole. Then, the main control board base box is lowered down. At this time, the guide slope at the bottom of the elastic buckle abuts against the outer edge of the rear side of the mounting hole, thereby compressing the elastic buckle inward, so that the end of the elastic buckle can pass through the mounting hole from the outside of the refrigerator shell to the inside of the refrigerator shell. When the end of the elastic buckle enters the inside of the refrigerator shell, since the guide slope is no longer restricted, the elastic buckle resets, so that the end of the elastic buckle undergoes elastic deformation outward and resets, so that the end of the elastic buckle can abut against the inner side of the refrigerator shell. At the same time, the flange above the elastic buckle also restricts the main control board base box from moving further downward, thereby completing the work of fixing the main control board base box to the refrigerator shell. In this way, the main control board back box is quick and easy to install, and it is not easy to fall off, with strong stability. Attached Figure Description

[0023] Reference Figures 1 to 2 An installation structure for a refrigerator's main control board base box, comprising:

[0024] The refrigerator shell 10 (not fully shown in the attached drawing) has mounting holes 11 that extend through the inside and outside.

[0025] The main control board base box 20 has a cavity 21. A flange 22 is provided on the outer periphery of the main control board base box 20. A wire conduit 23 is provided at the front end of the main control board base box 20 below the flange 22 and extending outward. The wire conduit 23 is connected to the cavity 21. An elastic buckle 24 is provided at the rear side of the main control board base box 20 below the flange 22. The end of the elastic buckle 24 extends upward and gradually tilts towards the outside of the main control board base box 20 so that the bottom of the elastic buckle 24 forms an inclined guide slope.

[0026] The main control board base box 20 is installed into the mounting hole 11 and the flange 22 abuts against the outer surface of the refrigerator shell 10. The wire conduit 23 is located at the lower end of the refrigerator shell 10. The elastic buckle 24 can pass through the mounting hole 11 from the outside of the refrigerator shell 10 under the action of the guide slope, and the end of the elastic buckle 24 can abut against the inner side of the refrigerator shell 10.

[0027] During installation, first tilt the main control board base box 20 and insert the wire conduit 23 into the refrigerator shell 10 along the front side of the mounting hole 11. During this process, the flange 22 is located on the outer surface of the refrigerator shell 10, so that the wire conduit 23 and the flange 22 above the wire conduit 23 clamp the part of the refrigerator shell 10 at the front edge of the mounting hole 11. Then, lower the main control board base box 20. At this time, the guide slope at the bottom of the elastic buckle 24 abuts against the outer edge of the rear side of the mounting hole 11, thereby compressing the elastic buckle 24 inward, so that the end of the elastic buckle 24 can be released from the outer edge of the mounting hole 11. The outer side of the refrigerator shell 10 extends beyond the mounting hole 11 to the inner side of the refrigerator shell 10. When the end of the elastic buckle 24 enters the inner side of the refrigerator shell 10, the elastic buckle 24 resets because the guide slope is no longer restricted. This causes the end of the elastic buckle 24 to elastically deform outward and reset, allowing it to abut against the inner surface of the refrigerator shell 10. Simultaneously, the flange 22 above the elastic buckle 24 restricts further downward movement of the main control board base box 20, thus completing the process of fixing the main control board base box 20 to the refrigerator shell 10. In this way, the installation of the main control board base box 20 is quick and convenient, and it is not easily detached, exhibiting strong stability.

[0028] If it is necessary to further secure the main control board base box 20 and the refrigerator shell to further strengthen the connection, it is only necessary to provide a set of mounting holes 11 on the flange 22, and to provide a connection hole on the refrigerator shell 10 that is opposite to the mounting holes 11. Positioning locking bolts are installed in the mounting holes 11 and the connection holes. The connection strength can be enhanced by a set of mounting holes 11, and the tightening degree of the positioning locking bolts on the set of mounting holes 11 does not need to reach the tightening degree of the prior art.

[0029] Considering that the main control board box generally requires grounding, and to simplify the structure, it is preferable to provide a connecting platform 25 on the flange 22 on the same side as the conduit 23. The connecting platform 25 has a connecting cavity, and the outer side of the connecting platform 25 has an insertion hole communicating with the connecting cavity. The edge of the mounting hole 11 has a grounding insert 30 facing the insertion hole. The grounding insert 30 can be inserted into the connecting cavity along the insertion hole. The connecting hole is located on the grounding insert 30, and the mounting hole 11 is located on the bottom surface of the connecting cavity. Furthermore, it is preferable that the mounting hole 11 has an internal thread that mates with the positioning bolt, so that the positioning locking bolt can be directly screwed into the mounting hole 11.

[0030] Further optimization is preferred, the edge of the mounting hole 11 is provided with a mating notch 12 that cooperates with the elastic buckle 24. The width of the mating notch 12 is less than the length of the elastic buckle 24's end deformed towards the outside of the main control board bottom box 20 in its natural state, so as to facilitate the elastic buckle 24 to be snapped into the inside of the refrigerator shell 10.

[0031] Preferably, the front end of the main control board base box 20 is provided with two wire conduits 23. The two wire conduits 23 are evenly arranged on both sides of the front end of the main control board base box 20. Preferably, the two wire conduits 23 are inclined towards the left and right sides of the main control board base box 20 to form a diffuse shape. The maximum distance between the two wire conduits 23 is not greater than the maximum length of the mounting hole 11.

[0032] In a further improvement, a sealing gasket is provided between the flange 22 and the outer surface of the refrigerator shell 10, thereby improving the sealing performance.

[0033] 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.
