CN202254606U - Door shelf of refrigerator - Google Patents

Abstract

The utility model relates to a door shelf of a refrigerator, in particular to a cover for the door shelf of the refrigerator, which aims to solve the problems that the conventional cover for the door shelf of the refrigerator cannot be simultaneously opened and closed smoothly, makes large noises and cannot be closed without collision. The door shelf of the refrigerator comprises a door shelf base, a door shelf support and a door shelf cover, wherein the door shelf cover is connected with the door shelf support through a torsion spring; one end of the torsion spring is clamped into a corresponding sliding slot of the door shelf support; and the other end of the torsion spring is fixed on the door shelf cover. The falling speed of the door shelf cover is reduced through a resetting force caused by elastic deformation of the spring, the collision between the door shelf cover and the base is avoided, large noises are avoided, the door shelf is protected, and the service life of the door shelf is prolonged.

Description

A kind of refrigerator doors shelf

Technical field

The utility model relates to this member of door compartment of refrigerator, especially relates to the lid of refrigerator doors shelf.

Background technology

Shelf on the refrigerator doors is equipped with this member of lid, thereby can be so that be positioned over article health in the door compartment, be difficult for dropping.But present door compartment lid is assembled up through rotating shaft, so just is easy to generate two problems; One is if the tension of assembling, door compartment lid open-close having some setbacks very so, and another one is; If assembling is loose excessively, becomes flexible easily in the time of shelf lid open and close, and be easy to generate sound when closing; Simultaneously, collision gate shelf base in closing course also causes the damage of door compartment lid and base easily for a long time.Therefore, in the time of how can realizing the lid open closed of door compartment, promptly do not have the sound of portion's article direct collision, folding freely and smoothly again becomes urgent problem in the assembling of refrigerator doors shelf.

The utility model content

Can not realize smooth and easy folding simultaneously to present refrigerator doors shelf lid; And there are not sound, the closed problem of collisionless; The utility model provides a kind of refrigerator doors shelf; Comprise that door compartment base, door compartment support and the door compartment lid, said door compartment lid is wound with a torque spring through its two ends rotating shaft and door compartment support and connection in the said rotating shaft; One end of said torque spring is stuck in the groove of said door compartment support, and an other free end passes " ︵ " shape chute of said door compartment support and places in the draw-in groove on the said door compartment lid.

As the improvement of the utility model, the free end that said torque spring is positioned at draw-in groove is provided with torsion spring and emits.

Owing to adopted torque spring as connecting elements at refrigerator doors shelf lid with between supporting, replaced the mode of original direct rotating shaft rotational fixation, so can be suitable in assembling loosen; So just guaranteed the smooth and easy of door compartment lid open-close; Simultaneously, because the process that falls of door compartment lid is the deformation process of torque spring, so the restoring force that itself has can interact with gravity; Reduce the active force of gravity to the door compartment lid; Thereby make door compartment cap closure process obtain buffering, not only avoided the sound, and reduced the impact force between door compartment lid and the door compartment base; Thereby make door compartment lid and base all obtain protection, prolonged the service life of each parts of door compartment.Because the outer wall of rotating shaft is to be screw-shaped, so the frictional force when further increasing it and falling reduces the impulsive force of door compartment lid to the door compartment base.Simultaneously, this structure makes that also fixing of torque spring is more firm.

Simultaneously, owing to the utility model discloses free end that said torque spring is positioned at draw-in groove and be provided with torsion spring and emit; Thereby guarantee torque spring and the door compartment lid smoothness of fixation stability property and rotation each other; Make that torque spring in use is not easy from chute, to skid off, guaranteed the stability that torque spring uses.

In a word; After having adopted above technical scheme, the contrast of the utility model and prior art, the restoring force that the elastic deformation through spring brings has slowed down the speed that the door compartment lid falls; Solved the problem of clashing between door compartment lid and the base; Not only avoid the generation of the huge sound, and protected the door compartment member, prolonged the service life of door compartment.

Wherein 1-door compartment base, 2-door compartment lid, the support of 3-door compartment, 4-chute, 5-torque spring, 6-rotating shaft, 5-1-torsion spring emit, 2-1-torque spring draw-in groove.

The specific embodiment

Embodiment 1

As depicted in figs. 1 and 2, the refrigerator doors door compartment supports 3 by door compartment base 1, door compartment lid 2, door compartment and constitutes.Wherein, connect the two ends of torque spring 5 through torque spring 5 between door compartment lid 2 and door compartment support 3; One end is fixed on door compartment and supports above 3; An other end is a movable end, is stuck in door compartment and supports in the chute 4 on 3, after chute 4 is passed on its top; Insertion is positioned at the torque spring draw-in groove 2-1 above the door compartment lid 2, and torsion spring is installed is emitted 5-1 on its top.When door compartment lid 2 opens and closes, drive torque spring 5 and in chute 4, slide.The hollow space of torque spring 5 is enclosed within above the rotating shaft 6.The original state of torque spring 5 is door compartment lid 2 open modes, and when door compartment lid 2 was closed, torque spring produced elastic deformation; Therefore has restoring force; This restoring force forms a pair of rightabout strength with the gravity that makes door compartment lid 2 fall to closing, thereby has reduced the speed and vigor that door compartment lid 2 falls, and has formed the cushion effect that door compartment lid 2 falls; Thereby reached the impulsive force that weakens between door compartment lid 2 and the door compartment base 1; Avoid collision each other, not only solved the problem of collision sound, and prolonged the service life of each member of door compartment.

Claims (2)

1. refrigerator doors shelf; Comprise that door compartment base (1), door compartment support (3) and door compartment lid (2); Said door compartment lid (2) supports (3) through its two ends rotating shaft (6) and door compartment and is connected; It is characterized in that: be wound with a torque spring (5) in the said rotating shaft (6); One end of said torque spring (5) is stuck in the groove of said door compartment support, and an other free end passes " ︵ " shape chute (4) of said door compartment support and places in the draw-in groove (2-1) on the said door compartment lid (2).

2. a kind of refrigerator doors shelf as claimed in claim 1 is characterized in that: the free end that said torque spring is positioned at draw-in groove (2-1) is provided with torsion spring and emits.
