Description

Technical Field

[0001] The utility model belongs to the field of hinges. Background Art

[0002] At present, hinges are installed on the refrigerator door body to enable the refrigerator door to open. However, most of the existing hinges do not have damping. When opening the door, if the force is large, it is easy to hit other objects, and the use is not safe enough. Therefore, damped hinges have emerged on the market. However, the resistance of the existing damped hinges is fixed and cannot be adjusted. Under the condition of limited space, if the damping is insufficient, there will still be a collision when opening the door, and the applicability is not ideal. Summary of the Utility Model

[0003] In view of the defects of the existing damped hinges, the technical problem to be solved by the utility model is to provide a damped hinge with a relatively simple structure and the resistance of which can be freely adjusted according to requirements.

[0004] To achieve the above object, according to one aspect of the utility model, the utility model is realized by the following technical measures: A damped hinge, comprising: a main body and a hinge part. An installation part is provided on the main body, and the installation part enables the main body to be installed on the door body.

[0005] The main body is U-shaped and is composed of two vertical plates and a horizontal plate connecting the two vertical plates. A through slot is provided on the horizontal plate.

[0006] The hinge part includes: a push rod, a swing arm, a rotating shaft and a spring.

[0007] The push rod is arranged in the main body, and a guiding slot is provided on the upper side of the push rod and cuts through the push rod. The upper side of the push rod is hinged to the main body through a pin shaft I passing through the guiding slot. A spring resisting rod is also provided on the push rod.

[0008] The spring is sleeved on the push rod and is located between the pin shaft I and the spring resisting rod.

[0009] One end of the swing arm passes through the through slot and is hinged to the lower side of the push rod through a pin shaft II. A rotating shaft is also provided on the swing arm. Rotating the rotating shaft can make the swing arm drive the push rod to rotate outwards to compress the spring.

[0010] For this damped hinge, by rotating the rotating shaft, the swing arm drives the push rod to rotate outwards to compress the spring, and the damping strength is freely adjusted according to the degree of spring compression.

[0011] Furthermore, a notch is provided in the middle of the two vertical plates of the main body. Through the notch, the middle parts of the two vertical plates can be bent outwards to form a fixing part. The design of this fixing part not only facilitates production but also is convenient for fixing.

[0012] Further, an insertion interface is provided at the lower end of the push rod, and one end of the swing arm passing through the through slot is inserted into the insertion interface and pinned by a pin II.

[0013] Further, the swing arm is composed of a swing arm seat, an insertion joint, and a connecting rod. A screw hole is provided on the swing arm seat. The insertion joint is used to connect the lower end of the push rod. The connecting rod is composed of a cross bar and an inclined bar. The cross bar is connected to the swing arm seat, and the inclined bar is connected to the insertion joint.

[0014] Further, the rotating shaft is composed of a sleeve column, a bolt, and a nut. The sleeve column is composed of a left sleeve column and a right sleeve column. A plug column with a diameter smaller than that of the left sleeve column extends from the right side of the left sleeve column. The plug column passes through the swing arm, and the left sleeve column and the right sleeve column can clamp the swing arm by passing the bolt through and tightening the nut with the bolt. By rotating the bolt, the push rod can be driven to rotate outward to compress the spring.

[0015] Compared with the prior art, the advantages of the present utility model are as follows: on the premise of maintaining the damping effect of the hinge, the magnitude of the damping can be freely adjusted by the user according to their own usage requirements.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] For descriptive purposes, the present disclosure may use spatial relative terms such as "beneath", "below", "under", "lower", "above", "over", "upper", and "side (e.g., as in "side wall")" to describe the relationship of one component to another (other) component as shown in the drawings. In addition to the orientation depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacturing. For example, if the device in the drawings is flipped over, a component described as "beneath" or "under" another component or feature will then be positioned "above" the other component or feature. Thus, the exemplary term "beneath" can encompass both the "above" and "below" orientations. In addition, the device may be otherwise positioned (e.g., rotated 90 degrees or at other orientations), and accordingly, the spatial relative descriptors used herein are to be interpreted accordingly.

[0022] As Figure 1 and Figure 2 shown, a damping hinge provided in this embodiment includes: a main body 1 and a hinge portion 2. The main body 1 is U-shaped and is composed of two vertical plates 3 and a horizontal plate 4 connecting the two vertical plates 3. A notch is formed in the middle of the two vertical plates 3 of the main body 1. Through the notch, the middle parts of the two vertical plates 3 can be bent outward to form a mounting portion 14, and the mounting portion 14 enables the main body 1 to be mounted on the refrigerator door body. A through slot is formed in the horizontal plate 4 of the main body 1. The hinge portion 2 includes a push rod 5, a swing arm 6, a rotating shaft 7, and a spring 8. The push rod 5 is movably fixed in the main body 1, and a guiding slot 9 penetrating through the push rod 5 is formed on the upper side of the push rod 5. The upper side of the push rod 5 is hinged to the main body 1 by a pin shaft I 10 passing through the guiding slot 9. A spring resisting rod 11 is further fixed on the push rod 5. The spring 8 is sleeved on the push rod 5 and is located between the pin shaft I 10 and the spring resisting rod 11. One end of the swing arm 6 passes through the through slot and is hinged to the lower side of the push rod 5 by a pin shaft II 12. A rotating shaft 7 is further provided on the swing arm 6. Rotating the rotating shaft 7 can enable the swing arm 6 to drive the push rod 5 to rotate outward to compress the spring 8.

[0023] As a preferred structure, an insertion interface 15 is machined at the lower end of the push rod 5. One end of the swing arm 6 passing through the through slot is inserted into the insertion interface 15 and is pinned by the pin shaft II 12. Such a setting is more reliable. The swing arm 6 is composed of a swing arm seat 16, an insertion joint 17, and a connecting rod 18. A screw hole 19 is further machined on the swing arm seat 16 for fixing. The insertion joint 17 is used to connect the lower end of the push rod 5. The connecting rod 18 is composed of a cross bar and an inclined bar. The cross bar is connected to the swing arm seat 16, and the inclined bar is connected to the insertion joint 17.

[0024] Further, the above-mentioned rotating shaft 7 is preferably composed of a sleeve column 20, a bolt 21 and a nut 22. The sleeve column 20 is composed of a left sleeve column 23 and a right sleeve column 24. A plug column with a diameter smaller than that of the left sleeve column 23 extends from the right side of the left sleeve column 23. The plug column passes through the swing arm 6, and the left sleeve column 23 and the right sleeve column 24 can clamp the swing arm 6 by passing the bolt 21 through and screwing the nut 22 with the bolt 21.

[0025] During use, the swing arm 6 is fixed on the outer shell of the refrigerator, and the main body 1 is fixed on the refrigerator door. By reversing the bolt 21, the push rod 5 swings outwards. During the swinging process of the push rod 5, the guide groove 9 will move upwards, so that the spring 8 presses against the pin shaft I 10. The amount of extrusion is determined according to the needs of the user. In this way, the hinge has a damping effect.
