Abstract

Disclosed is an automatic door closing mechanism of the refrigerator, comprising a door [1] and a body [6]. A shaft sleeve[3] is fixed on the door[1]; a shaft[5] is fixed on the body[6].The utility model is characterized in that a positioning part[7] is fixed on the shaft[5]; one end face of the positioning part[7] is contacted with one end face of the shaft sleeve[3]; one end face of the positioning part[7] comprises a horizontal surface[8] and an oblique plane[9] that forms an angle with the horizontal surface[8]; one end face of the shaft sleeve[3] comprises a horizontal surface[2] and an oblique plane[4] that forms an angle with the horizontal surface[2]. With the help of the weight of the door, when the door is closed, the oblique plane of the shaft sleeve contacts the oblique plane of the positioning part, and then the door is forced from the tangential direction of the circumference, and the tangential force drives the door to rotate to close the door.

Description

The door engine structure of refrigerator

Technical field

The utility model relates to a kind of door engine structure of refrigerator.

Background technology

In the prior art, the chamber door of refrigerator is closed the door after opening if desired, need send chamber door up to closing the door the position with hand, and therefore the operation of closing the door is not laborsaving, if utilize inertia to enforce chamber door, then impulsive force at closing time can be damaged the sealing of chamber door.Still there is not at present the mechanism that can close the door automatically after under door opening state, crossing critical point.

Summary of the invention

It is a kind of in the process of closing the door that the purpose of this utility model is to provide, and chamber door is crossed the door engine structure of the refrigerator that can close automatically after the critical point.

The technical solution of the utility model is: a kind of door engine structure of refrigerator, comprise chamber door, casing, be fixed with axle sleeve on the described chamber door, be fixed with rotating shaft on the described casing, described rotating shaft is inserted in the described axle sleeve and makes both pivotally connected, be fixed with keeper in the described rotating shaft, an end face of this keeper contacts with an end face of described axle sleeve, and an end face of described keeper comprises the keeper horizontal plane and is the keeper inclined-plane of an angle with this keeper horizontal plane; An end face of described axle sleeve comprise the axle sleeve horizontal plane and with this axle sleeve horizontal plane axle sleeve inclined-plane in a certain angle, be in complete door opening state or close fully under the state at chamber door, described axle sleeve horizontal plane contacts with the keeper horizontal plane; When chamber door was in complete door opening state and closes on the position between the state fully, described axle sleeve inclined-plane contacted with described keeper inclined-plane.

The utility model compared with prior art has following advantage:

Utilize the deadweight of chamber door, in the process of closing the door, the axle sleeve inclined-plane contacts with the keeper inclined-plane, the gravity of door can be decomposed into to the normal pressure of contact-making surface with along the power of tangent to periphery direction, this tangential force makes a rotation, close chamber door, this simple in structure, compact, there is the problem of wear out failure hardly.

Accompanying drawing 1 is a parts decomposing schematic representation of the present utility model;

Accompanying drawing 2 is the expanded view (under the door opening state) of axle sleeve and rotating shaft;

Accompanying drawing 3 is the expanded view (under the state of closing the door) of axle sleeve and rotating shaft; Wherein:

[1], chamber door; [2], axle sleeve horizontal plane; [3], axle sleeve; [4], axle sleeve inclined-plane; [5], rotating shaft; [6], casing; [7], keeper; [8], keeper horizontal plane; [9], keeper inclined-plane;

The specific embodiment

Referring to accompanying drawing 1 to accompanying drawing 3, a kind of door engine structure of refrigerator, comprise chamber door [1], casing [6], be fixed with axle sleeve [3] on the described chamber door [1], be fixed with rotating shaft [5] on the described casing [6], described rotating shaft [5] is inserted in the described axle sleeve [3] and makes both pivotally connected, be fixed with keeper [7] in the described rotating shaft [5], an end face of this keeper [7] contacts with an end face of described axle sleeve [3], and an end face of described keeper [7] comprises keeper horizontal plane [8] and is the keeper inclined-plane [9] of an angle with this keeper horizontal plane [8]; An end face of described axle sleeve [3] comprise axle sleeve horizontal plane [2] and with this axle sleeve horizontal plane [2] axle sleeve inclined-plane [4] in a certain angle, referring to accompanying drawing 2 and accompanying drawing 3, be in complete door opening state or close fully under the state at chamber door [1], described axle sleeve horizontal plane [2] contacts with keeper horizontal plane [8], and chamber door this moment [1] is in stable duty; When chamber door [1] is in complete door opening state and closes on the position between the state fully, described axle sleeve inclined-plane [4] contacts with described keeper inclined-plane [9], the gravity of chamber door [1] makes chamber door [1] be subjected to the power that circumferencial direction is tangential, and this power makes chamber door [1] to close automatically.In accompanying drawing 2 and the accompanying drawing 3, in order to represent keeper horizontal plane [8] and keeper inclined-plane [9] on the keeper [7], and the axle sleeve horizontal plane [2] on the axle sleeve [3] and axle sleeve inclined-plane [4], keeper [7] with draw after axle sleeve [3] separates, in the actual use, the end face of the end face of keeper [7] and axle sleeve [3] should be contacted.

Claims

1, a kind of door engine structure of refrigerator, comprise chamber door [1], casing [6], be fixed with axle sleeve [3] on the described chamber door [1], be fixed with rotating shaft [5] on the described casing [6], described rotating shaft [5] is inserted in the described axle sleeve [3] and makes both pivotally connected, it is characterized in that: be fixed with keeper [7] in the described rotating shaft [5], an end face of this keeper [7] contacts with an end face of described axle sleeve [3], and an end face of described keeper [7] comprises keeper horizontal plane [8] and is the keeper inclined-plane [9] of an angle with this keeper horizontal plane [8]; An end face of described axle sleeve [3] comprise axle sleeve horizontal plane [2] and with this axle sleeve horizontal plane [2] axle sleeve inclined-plane [4] in a certain angle, be in complete door opening state or close fully under the state at chamber door [1], described axle sleeve horizontal plane [2] contacts with keeper horizontal plane [8]; When chamber door [1] was in complete door opening state and closes on the position between the state fully, described axle sleeve inclined-plane [4] contacted with described keeper inclined-plane [9].
