AI Technical Summary

Technical Problem

Due to the thermal expansion, cold and shrinkage of foaming materials and the annular temperature, the size fluctuates greatly. Combined with the deviation of the hinge installation hole, the middle joints of the two doors and the height of the cross refrigerator door are uneven. The traditional solution increases the adjustment of the gasket, but wastes materials and is easily lost. Moreover, the connection between the traditional foot between the refrigerator door and the box is prone to forward tilt and thread loosening.

Method used

A coaxial anti-detachment hinge for up and down adjustment of refrigerator door body is adopted, including the hinge main body, bottom angle, hinge shaft and steel sleeve injection molded in the bottom angle. The threaded part of the hinge shaft is connected to the internal thread of the steel sleeve to achieve adjustable upper and lower positions of the door body, and the problem of forward tilt opening of the door is solved by moving the bottom foot forward.

Benefits of technology

The upper and lower positions of the refrigerator door body are adjusted, solving the problems of forward tilt and bottom corner falling off, improving the flatness and stability of the refrigerator door, and avoiding the problems of waste of materials and easy loss in traditional methods.

Description

Technical field:

[0001] The utility model relates to a coaxial anti-drop hinge for adjusting a refrigerator door up and down and a refrigerator, belonging to the technical field of refrigerators. Background technology:

[0002] The refrigerator door body is affected by the thermal expansion and contraction of the foam material and the ambient temperature, and the door body size fluctuates to a certain extent. In addition, due to the deviation of the hinge mounting holes, most refrigerators have problems such as uneven center seams between the two doors and unequal heights of cross refrigerator doors. The traditional solution is to add gaskets for adjustment, which wastes materials and is easy to lose.

[0003] With the development of thinner and lighter refrigerator materials and smaller presses, the traditional base is between the refrigerator door and the box, and the risk of the product, especially large refrigerators, tipping forward when the door is opened is invisibly increased.

[0004] Moreover, the traditional base threaded connection is prone to problems such as plastic screw thread stripping and base loosening if rotated too many times.

[0005] Therefore, it is necessary to improve the existing technology to solve the shortcomings of the existing technology. Utility model content:

[0006] The utility model aims to solve the problems existing in the above-mentioned prior art and provides a coaxial anti-detachment hinge for adjusting the refrigerator door up and down and a refrigerator, which can realize the adjustable up and down position of the door body and solve the problems of the door body tilting forward and the bottom corner falling off.

[0007] The utility model adopts the following technical scheme: a coaxial anti-detachment hinge for adjusting the refrigerator door up and down, comprising a hinge body, a bottom angle, a hinge shaft and a steel sleeve injection-molded in the bottom angle, the hinge shaft comprising a smooth portion located in the upper section and a threaded portion located in the lower section, an internal thread matching the threaded portion is formed on the inner surface of the steel sleeve, the hinge body is threadedly connected to the threaded portion and is located above the bottom angle.

[0008] Furthermore, the lower surface of the steel sleeve is located above the lower surface of the bottom angle.

[0009] Furthermore, when the threaded portion of the hinge shaft is screwed and installed on the steel sleeve, the lower end of the hinge shaft extends beyond the lower surface of the steel sleeve.

[0010] Furthermore, a hexagonal sink is provided at the bottom of the hinge shaft.

[0011] Furthermore, the upper end of the hinge shaft is installed in the refrigerator door.

[0012] The utility model also adopts the following technical solution: a refrigerator, characterized in that the aforementioned coaxial anti-detachment hinge for adjusting the refrigerator door up and down is used.

[0013] The utility model has the following beneficial effects: the utility model is used for the coaxial anti-detachment hinge and refrigerator for adjusting the refrigerator door up and down, solves the problem of the refrigerator door tilting forward by moving the base forward and the fulcrum forward; and realizes the up and down adjustment of the door by changing the relative position of the hinge body and the hinge axis. Description of the drawings:

[0014] Figure 1 The utility model is a schematic diagram of a coaxial anti-drop hinge for adjusting a refrigerator door up and down.

[0015] Figure 2 This is another schematic diagram of the coaxial anti-drop hinge for adjusting the refrigerator door up and down according to the utility model.

[0016] Figure 3 It is a schematic diagram of the installation of the hinge axis and the bottom angle of the utility model. Specific implementation method:

[0017] The utility model is further described below in conjunction with the accompanying drawings.

[0018] The utility model discloses a coaxial anti-drop hinge for adjusting a refrigerator door up and down, comprising a hinge body 1, a bottom corner 2, a hinge shaft 3 and a steel sleeve 4 injection-molded in the bottom corner 2, wherein the lower surface of the steel sleeve 4 is located above the lower surface of the bottom corner 2.

[0019] The hinge shaft 3 includes a smooth portion 30 at the upper section and a threaded portion 31 at the lower section. An internal thread (not shown) matching the threaded portion 30 is formed on the inner surface of the steel sleeve 4. When the threaded portion 31 of the hinge shaft 3 is screwed onto the steel sleeve 4, the lower end of the hinge shaft 3 extends beyond the lower surface of the steel sleeve 4.

[0020] The hinge body 1 is threadedly connected to the threaded portion 31 and is located above the bottom corner 2 .

[0021] The utility model is a coaxial anti-detachment hinge for adjusting the refrigerator door up and down, and its working principle is as follows: the upper end of the hinge shaft 3 is installed in the refrigerator door, and the bottom of the hinge shaft 3 is provided with a hexagonal sink (not shown in the figure). The hinge shaft 3 is twisted with a hexagonal wrench to change the relative position between the hinge shaft 3 and the hinge body 1. During the actual assembly of the cabinet, the hinge body 1 is tightly connected to the bottom of the refrigerator cabinet. The relative position of the hinge body 1 and the hinge shaft 3 changes, thereby realizing the relative change of the height position of the door body and the cabinet.

[0022] The bottom foot 2 of the coaxial anti-detachment hinge for adjusting the refrigerator door up and down moves forward, thereby causing the fulcrum to move forward. After the door is opened, the force arm of the door body bearing material is reduced, and the force arm of the center of gravity of the box is increased, thereby effectively improving the problem of the door tilting forward when opened.

[0023] The utility model is used for the coaxial anti-slip hinge for adjusting the refrigerator door up and down, wherein the steel sleeve 4 is threadedly connected to the hinge shaft 3 through an internal thread. After assembly, the part of the hinge shaft 3 exposed from the steel sleeve 4 at the bottom is riveted, and the shaft diameter of the bottom of the hinge shaft 3 is increased and larger than the internal thread hole of the steel sleeve 4, thereby achieving anti-slipping without affecting the adjustment function of the base foot.

[0024] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
