Description

An adjustable door hinge installation structure for a refrigerator

technical field

The utility model relates to an adjustable door hinge installation structure for a refrigerator, which belongs to the improvement technology of the existing door hinge installation structure for a refrigerator.

Background technique

In current refrigerators, the door hinge is a connector (as shown in Figure 1 ) between the refrigerator door and the casing, and is generally located at the top and bottom of the refrigerator. It mainly includes a door hinge fixing plate 8, on which a plurality of fixing holes 10 and a hinge shaft hole 11 are arranged, and the refrigerator door 1 and the box body 4 are connected by screws 3 or rivets. Whether the door hinge is properly installed has a great influence on whether the refrigerator door is opened and closed smoothly and whether the refrigerator is tightly sealed after the door is closed. Current door hinges generally have two structures, one of which is shown in Figure 2: the fixing holes and hinge shaft holes on the door hinge fixing plate 8 are all non-adjustable round hole structures, and the door hinge shaft and the fixing plate are solidified into a An integral door hinge, the bolt passing through the fixing hole connects the door to the refrigerator body. The position of the door and the refrigerator cannot be adjusted in this connection structure. The advantage of this structure is that there is no free space for the door hinge installation position, and the installation of the hinge is simple. Reliable, good consistency in production, but if it is necessary to adjust the installation position of the door due to the manufacturing error of some parts and the cumulative error of assembly, etc., it is necessary to disassemble all the connecting parts involved and renovate the original parts. Some parts will even be scrapped until the door is adjusted to fit properly. Such a structural process has poor operability, requires a high level of process manufacturing and sophisticated manufacturing equipment, and thus produces relatively high manufacturing costs.

Another one is shown in Figure 3, the fixing hole 10 on the fixing plate 8 adopts a waist-shaped structure, the door hinge shaft and the hinge fixing plate are connected by riveting or threading, and the two are solidified into an integral door hinge during installation. Although the structure can realize the position adjustment during the door installation, the door hinge has a relatively large free movement space, and the fluctuation of each installation position is relatively large, so the possibility of adjusting the installed door will greatly increase, and because the hinge is fixed during installation The plate is fixed by three bolts, and the adjustment can only be realized after removing the three bolts every time during the adjustment. In short, this kind of structural door needs to be adjusted frequently, and each adjustment operation is also relatively troublesome.

Utility model content

The technical problem to be solved by the utility model is to overcome the shortcomings of the existing door hinge installation structure that cannot be adjusted and the operation is relatively difficult although it can be adjusted, and provide a new adjustable door hinge installation structure with a simple structure. The door hinge installation structure is reliable in installation , high installation efficiency, good workmanship, and it is also very convenient to adjust the position between the refrigerator door and the cabinet.

The technical solution for realizing the purpose of this utility model is: an adjustable door hinge installation structure for a refrigerator, including a door hinge fixing plate and a hinge shaft, and the fixing plate is provided with a plurality of fixing holes for connecting bolts or rivets and a connecting hinge The hinge shaft hole for the shaft is characterized in that: the plurality of fixing holes are circular holes matching the cross-sectional size of the bolt or rivet, the size of the hinge shaft hole in the horizontal direction is larger than the cross-sectional size of the hinge shaft, and has Horizontally adjust the appropriate margin for the relative position of the hinge axis.

The hinge shaft hole is a strip hole or a round hole.

The length of the elongated hole or the diameter of the circular hole is 2-10 mm larger than the cross-sectional diameter of the hinge shaft.

The fixing hole of the door hinge fixing plate of the utility model adopts a common circular hole structure, and the door hinge shaft and the fixing plate are connected by threads. The two are solidified into an integral door hinge through nuts, and then the door hinge connects the door and the refrigerator body through bolt connection. Since the fixed connection of the door hinge fixing plate cannot be freely moved, the possibility of door adjustment is greatly reduced. When it is necessary to adjust the installation position of the door due to the manufacturing error of some parts and the cumulative error of assembly, etc., it is only necessary to loosen the nut on the hinge shaft, and after the door is adjusted to a suitable position, tighten the nut to complete the adjustment of the door.

Detailed ways

As shown in Figures 4, 5, and 7, the door hinge of this structure is composed of a nut 5, a washer 6, a washer 7, a door hinge fixing plate 8, and a door hinge shaft 9, and the washers 6 and 7 are optional parts of the national standard. The door hinge fixing plate 8 is provided with three circular fixing holes 10 and a strip-shaped hinge shaft hole 11 . That is, the connection between the door hinge fixing plate 8 and the box body adopts a circular fixing hole structure, and the connection between the door hinge shaft 9 and the hinge fixing plate 8 adopts an elongated hole structure, and the door hinge shaft 9 and the door hinge fixing plate 8 pass through during installation. The nut 5 is solidified into an integral door hinge, and then the door and the refrigerator body are connected by bolts through the fixing holes 10. Since the door hinge fixing plate 8 is fixedly connected with the door and the refrigerator body and cannot move freely, the possibility of adjusting the door is greatly reduced If it is necessary to adjust the installation position of the door due to the manufacturing error of some parts and the cumulative error of assembly, etc., it is only necessary to loosen the nut 5 on the door hinge shaft 9, and after the door is adjusted to a suitable position, tighten the nut to complete the door. adjustment.

The installation steps are as follows: first, the nut 5, the washer 6, the washer 7, the door hinge fixing plate 8, the door hinge shaft 9, etc. are formed into the door hinge 2; then the door hinge 2 is fixed on the bottom of the box 4 with 3 screws, Then use three screws 3 to connect the door hinge 2 to the door 1 and be fixed on the top of the casing 4. Because the door hinge fixing plate 8 and the fixing hole of the casing 4 adopt a circular hole structure, it is simple and reliable during installation, and the efficiency is relatively high. If the installation position of the door needs to be adjusted because of reasons such as part manufacturing error and assembly cumulative error, you only need to loosen the nut 5, and after the door 1 is adjusted to a suitable position, the nut 5 on the door hinge shaft 9 can be locked.

Wherein the hinge shaft hole 11 on the door hinge fixed plate 8 can also be designed as a large circular hole as shown in accompanying drawing 6, the diameter of this circular hole needs to be greater than the cross-sectional size of the door hinge shaft 9, so that it has an adjustment when needed Space. Therefore, this structure can also achieve the same technical effect as in the above-mentioned embodiments.
