Description

Technical Field

[0001] The utility model relates to the technical field of door hinges, and in particular to an opening and closing limiting mechanism of an ice-making machine door. Background Art

[0002] In refrigeration products, such as ice makers, refrigerators, display cabinets, etc., most of the door bodies mainly adopt upper and lower hinge structures. The above-mentioned refrigeration products have the following problems during use: First, when the user closes the door body with a little force, the door body will rebound, resulting in the door body not closing tightly. In addition, when the door body is in the closed state, due to the weight of the refrigerator door itself and the items loaded on the door (such as large bottles of beverages, etc.), a large inertia effect will be generated, and the door body will rotate on its own. Second, when the door body is opened, since there is no limiting structure, it is very easy to hit the surrounding walls or other obstructions, which will cause movement damage to the door body and affect the user experience. In view of this, it is necessary to improve the existing technology. Utility Model Content

[0003] The purpose of the utility model is to provide an opening and closing limit mechanism for an ice maker door, aiming to solve at least one of the technical problems existing in the above-mentioned prior art. To achieve the above-mentioned purpose, the technical solution adopted is as follows:

[0004] An ice machine door opening and closing limit mechanism comprises a cabinet and a door, wherein one side of the door is hinged to the same side of the cabinet through an upper hinge and a lower hinge;

[0005] The lower hinge includes a lower hinge seat and a lower hinge plate. The lower hinge seat is L-shaped and includes a fixed plate and a load-bearing plate. The fixed plate is fixedly connected to the bottom front side wall of the cabinet. A shaft sleeve is vertically arranged on the upper surface of the load-bearing plate. The lower hinge plate is fixedly installed on the bottom wall of the door body. A rotating shaft is vertically arranged on the lower surface of the lower hinge plate. The rotating shaft is rotatably installed in the shaft sleeve.

[0006] A first limiting column is also provided on the lower surface of the lower hinge plate, and a first clamping column is vertically provided on the cabinet body inside the load-bearing plate. The end of the first clamping column is bent inwardly to form a second clamping column, and a clamping groove is formed inside the connection between the first clamping column and the second clamping column. When the door body is closed, the first limiting column first contacts the second clamping column and causes the second clamping column to elastically displace outward. When the door body is completely closed, the second clamping column is reset and the first limiting column is clamped in the clamping groove.

[0007] A second limiting column is also provided on the lower surface of the lower hinge plate, and the outer edge of the load-bearing plate is provided with continuous arc sections and straight sections. When the door body is opening, the second limiting column can slide along the arc section.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] In addition, in the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] like Figure 1 As shown, a preferred embodiment of the utility model provides an ice maker door opening and closing limit mechanism, which includes a cabinet 1 and a door 2, and one side of the door 2 is hinged to the same side of the cabinet 1 through an upper hinge and a lower hinge.

[0021] The upper hinge includes an upper hinge plate, which is fixedly installed on the top wall of the cabinet body 1 by bolts, and the upper hinge plate extends forward from the cabinet body 1. A hinge shaft is fixed and vertically installed on the lower surface of the upper hinge plate extending out of the cabinet body 1. A hinge hole is provided on the top wall of the door body 2, and the hinge shaft on the upper hinge plate can be rotatably installed in the hinge hole.

[0022] The lower hinge includes a lower hinge seat and a lower hinge plate 3, wherein the lower hinge seat includes a fixing plate 4 and a bearing plate 5, and the lower hinge seat is L-shaped, that is, the fixing plate 4 and the bearing plate 5 are vertically fixedly connected. The fixing plate 4 is fixedly connected to the bottom front side wall of the cabinet body 1 by bolts, and a shaft sleeve 6 is vertically provided on the upper surface of the bearing plate 5. The lower hinge plate 3 is fixedly installed on the bottom wall of the door body 2 by bolts, and a rotating shaft 7 is vertically provided on the lower surface of the lower hinge plate 3, and the rotating shaft 7 is rotatably installed in the shaft sleeve 6.

[0023] Based on the above arrangement, the door body 2 is rotatably connected to the cabinet body 1 via an upper hinge and a lower hinge.

[0024] like Figure 2 As shown, a first limiting column 8 is further provided on the lower surface of the lower hinge plate 3, and the first limiting column 8 is located on the inner side of the rotating shaft 7. A first clamping column 9 is vertically provided on the cabinet body inside the load-bearing plate 5, and the first clamping column 9 is fixedly installed on the cabinet body 1 by bolts, and the end of the first clamping column 9 is bent inward to form a second clamping column 10, and a clamping groove 11 is formed inside the connection between the first clamping column 9 and the second clamping column 10.

[0025] When the door body 2 is closing, the first limiting column 8 first contacts the second clamping column 10, and causes the second clamping column 10 to elastically displace outward. When the door body is completely closed, the second clamping column 9 is reset, and the first limiting column 8 is stuck in the clamping slot 11. The clamping slot 11 limits the first limiting column 8, so that the door body 2 will not rotate by itself even if there is inertia due to its own weight, and plays a locking role in the closed state. When opening the door body, the user needs to slightly turn the door body to make the first limiting column 8 slide out of the clamping slot 11.

[0026] Furthermore, the first clamping column 9 is made of plastic material. In addition, a strip-shaped through hole 12 is provided on the first clamping column 9 along the length direction of the first clamping column 9 to increase the elasticity of the first clamping column 9 and prevent it from breaking.

[0027] like Figure 3 As shown, a second limiting column 13 is further provided on the lower surface of the lower hinge plate 3, and the second limiting column 13 is located between the first limiting column 8 and the rotating shaft 7. A continuous arc section 14 and a straight section 15 are provided on the outer edge of the load-bearing plate 5.

[0028] When the door body 2 is opening, the second limiting column 13 can slide along the arc section 14. When the door body 2 is opened to a certain angle, such as 90°, the straight section 15 contacts the second limiting column 13 and restricts the second limiting column 13 from sliding further, thereby limiting the opening angle of the door body 2. The door body 2 is effectively prevented from colliding with the surrounding walls or cabinets, thereby improving the user experience.

[0029] Most of the existing refrigeration equipment adopts embedded installation. In order to pursue integrity and aesthetics, a decorative panel is detachably installed on the front side of the door body. The style and color of the decorative panel can be freely customized according to needs.

[0030] In summary, the ice maker door opening and closing limit mechanism described in the embodiment of the utility model can lock the door body when it is closed to prevent it from rotating on its own. In addition, when the door body is opened to a certain angle, it can limit the door body to prevent it from colliding with surrounding walls or cabinets, thereby improving the user experience.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
