Description

Technical Field

[0001] The invention relates to the technical field of refrigerator glass doors, in particular to a door shaft base structure for a display cabinet glass door. Background Art

[0002] At present, refrigerator glass doors are divided into two categories, with or without frames and with frames. The glass door of the frameless refrigerator is fixed by installing the upper and lower door hinges on the box body. After fixing, the glass door cannot be fine-tuned. If there is a problem with the installation and adjustment is required, the glass door hinge needs to be reinstalled. The base of the glass door with a frame is installed on the frame, which is more convenient to install than the frameless one. The base can be directly fixed on the frame. After the position and size are designed in the factory, the glass door can be directly installed, and there will be basically no problems. However, it is difficult to make the glass door 100% correct in the actual production process. In the actual transportation process, it is inevitable that some rough loading and unloading, unsafe installation during the installation process, and other unexpected situations will occur, which directly lead to the deformation of the frame and the glass door. The situation needs to be fine-tuned. If the refrigerator cannot be adjusted, the cold will leak, the door seal will wear, the glass door will sag, the insulation performance of the refrigerator will decrease, and condensation will occur around the glass door, affecting the appearance and performance. Summary of the invention

[0003] The purpose of the present invention is to solve the deficiencies of the above-mentioned technology and provide a door axis base structure for a display cabinet glass door, which can adjust the door axis position of the display cabinet glass door to ensure good fit between the glass door and the door frame.

[0004] In order to achieve the above-mentioned purpose, the present invention is a door axis base structure for a display cabinet glass door, comprising a base, an axis body and an adjusting bolt, wherein the base is a long flat plate structure, and one end of the base in the length direction is folded upward to form a folding portion, a long groove is arranged on the base along the length direction, the lower end of the axis body is arranged inside the long groove, and the axis body and the long groove are slidably connected, a connecting body is arranged on the axis body near one end of the folding portion, the connecting body extends toward one end of the folding portion of the base and bends upward to form a connecting portion, and a through hole or a slot for cooperating with the adjusting bolt is arranged on the connecting portion of the connecting body, a screw hole is arranged on the folding portion of the base corresponding to the through hole or the slot, and the adjusting bolt and the screw hole after cooperating with the through hole or the slot are connected by a thread.

[0005] In the above technical solution, the lower end of the shaft body is arranged inside the long groove, and the two are slidably connected, and the position of the shaft body in the long groove is changed by adjusting the bolt and the connecting part of the connecting body arranged on the shaft body, and the adjusting bolt and the folding part on the base are adjusted to achieve the adjustment. When the glass door and the door frame are not matched, the relative position of the shaft body on the base can be adjusted to change the position of the glass door to achieve adjustment. The relative position of the door axis can be adjusted by changing the position of the base and the shaft body by adjusting the bolt, so that the relative position of the door axis can be adjusted to change the angle of the glass door. In addition, the shaft body is confined in the long groove, and the connecting body and the base are connected by adjusting the bolt, so the axial position of the shaft body and the position in the length direction of the long groove are limited, which is simple and convenient with high stability.

[0006] A downwardly extending shell is provided at the long groove on the lower surface of the base, and the hollow section inside the shell is consistent with the size of the long groove. A sliding block is formed at the lower end of the shaft body, and the sliding block is located inside the long groove and the shell. The width of the sliding block is consistent with the width of the long groove, and the length of the sliding block is less than the length of the long groove. The lower end of the sliding block is located inside the shell. The design of this structure can set the sliding block formed at the lower end of the shaft body inside the long groove and the inner shell, so that it has high stability during the sliding process, and when it is assembled on the door frame, the sliding of the sliding block will not be interfered by external components, so as to ensure the stability and reliability of the adjustment.

[0007] Two limit blocks are arranged on the adjusting bolt near one end of the connecting body, and there is a gap between the limit blocks. When the adjusting bolt is matched with the slot on the connecting part, the two limit blocks are respectively located on both sides of the slot of the connecting part and fit with the connecting part. The design of this structure can realize the bidirectional restriction of the shaft body in the length direction of the base, and the restriction process is simple and convenient, so that the shaft body can be positioned in the long slot, and the stability after positioning is high.

[0008] A positioning hole is provided in the middle part of the base near one end of the folding part, and a limiting protrusion is provided on the side of the connecting part near the folding part, the limiting protrusion is distributed on the edge of the slot, and the distribution range of the limiting protrusion on the connecting part is smaller than the range of the positioning hole; when the sliding block contacts the shell near one end of the folding part, the limiting protrusion is located in the range of the positioning hole away from one end of the folding part; when the adjusting bolt is matched with the screw hole on the folding part, the distance between the lowermost end of the limiting block and the base is greater than the thickness of the connecting part, and less than the sum of the thickness of the limiting protrusion and the connecting part. The design of this structure is that during the assembly of the shaft body and the base, the limit block of the adjustment bolt is adjusted to the borrowing hole, and then the slot on the connection part is horizontally oriented toward the adjustment bolt, and the limit protrusion is placed inside the borrowing hole, and then the entire shaft body is rotated downward so that the sliding block at the bottom of the shaft body enters the shell, and finally the sliding block contacts the shell near the folding part. At this time, the slot is stuck on the adjustment bolt between the two limit blocks, and the limit protrusion is horizontally forward. Then the adjustment bolt can be rotated to move the shaft body away from the borrowing hole. When it moves slightly, the limit protrusion and the borrowing hole cannot match, so the entire shaft body cannot be flipped up, realizing a stable connection between the shaft body and the base, and it will not fall off during transportation and assembly, thereby improving performance. At the same time, the limit protrusion can be continuously distributed on the edge of the slot to strengthen the strength of the slot.

[0009] A fixing hole is arranged on the bottom of the shell and / or the base. The design of the fixing hole can further enhance the connection firmness between the base and the door frame.

[0010] The door shaft base structure for a display cabinet glass door obtained by the present invention can fine-tune the relative position between the shaft body and the base, and the connection stability and firmness between the shaft body and the base are high. BRIEF DESCRIPTION OF THE DRAWINGS
