Abstract
A novel refrigerator door shaft sleeve with four-freedom-degree limit comprises a shaft sleeve body, wherein the shaft sleeve body is provided with a door shaft hole for installing a door shaft; the lower part of the outer wall of the shaft sleeve body is provided with at least two elastic fins; and the clearance between the upper end of each elastic fin and a protruding retaining ring is greater than the thickness of a door shell. The novel refrigerator door shaft sleeve with four-freedom-degree limit provided by the utility model is convenient to assemble and excellent in reliability.
Description
Technical field
The utility model belongs to a kind of refrigerator doors axle sleeve.
Background technology
The door-hinge cover of refrigerator plays the effect that connects door-hinge and door shell, avoids door-hinge and door shell directly to rub, and mainly contains two kinds of citation forms at present: a kind of is that alignment pin and available self-tapping screw and the fixing structure of door shell are arranged; Another kind is that no alignment pin can not be used self-tapping screw and the fixing structure of door shell.
The door-hinge cover that has alignment pin installs time-consuming expense material, also fixing with self-tapping screw behind the door-hinge cover reeve door shell, just can avoid door-hinge cover play up and down.And the door-hinge cover that does not have alignment pin install after play up and down not only, also can left-right rotation, produce friction with door shell.
Summary of the invention
In order to overcome the relatively poor deficiency of assembling trouble, reliability of current refrigerator door-hinge cover, the utility model provides a kind of novel four-degree-of-freedom easy to assembly, that reliability is good spacing refrigerator doors axle sleeve.
The utility model solves the technical scheme that its technical problem adopted:
The refrigerator doors axle sleeve that a kind of novel four-degree-of-freedom is spacing; Comprise the axle sleeve body; Said axle sleeve body has the door-hinge hole that supplies door-hinge to install; At least two elasticity fins are installed in the outer wall bottom of said axle sleeve body, and the gap between the upper end of said elasticity fin and the said overhanging back-up ring is greater than the thickness of door shell.
Further; The open upper end place of said axle sleeve body is provided with overhanging back-up ring; The alignment pin of restriction left-right rotation is installed in the junction of said axle sleeve body and overhanging back-up ring; The upwards elasticity fin of play of two restrictions is installed in the outer wall bottom of said axle sleeve body, and two elasticity fins are symmetrically distributed in the both sides of axle sleeve body.
The technical conceive of the utility model is: alignment pin directly is connected with the door-hinge cover, has increased by two elasticity fins again on its two limits, the mounting plane that the end face of elasticity fin and door-hinge overlap have one be slightly larger than door shell thickness the gap.
Aim at the door-hinge trepanning on the door shell to it, directly inject door shell, beginning elasticity fin shrinks; The elasticity fin flicks at once after being inserted into the end, has withstood door shell, does not allow it moving up and down; And alignment pin has limited its rotation, and door-hinge cover itself has limited its moving all around.
The beneficial effect of the utility model mainly shows: easy to assembly, reliability is good.

Fig. 1 is the structural representation of the door-hinge cover of the utility model;
Fig. 2 is the upward view of Fig. 1;
Fig. 3 is the scheme of installation of door-hinge cover;
Fig. 4 is the sketch map in the door-hinge hole on the body.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1～Fig. 4; The refrigerator doors axle sleeve that a kind of novel four-degree-of-freedom is spacing; Comprise the axle sleeve body; Said axle sleeve body has the door-hinge hole 1 that supplies door-hinge to install, and at least two elasticity fins 3 are installed in the outer wall bottom of said axle sleeve body, and the gap between the upper end of said elasticity fin 3 and the said overhanging back-up ring is greater than the thickness of door shell.
The open upper end place of said axle sleeve body is provided with overhanging back-up ring; The alignment pin 2 of restriction left-right rotation is installed in the junction of said axle sleeve body and overhanging back-up ring; The outer wall bottom of said axle sleeve body install two restrictions upwards 3, two elasticity fins of elasticity fin of play be symmetrically distributed in the both sides of axle sleeve body.
With reference to Fig. 4; Have door-hinge hole 5 on the door shell; Said door-hinge hole supplies the door-hinge cover to install; Have on the said door-hinge hole and supply alignment pin alignment pin groove of installing and the fin groove that supplies the elasticity fin to install, the ultimate range between the center of circle in said fin groove and door-hinge hole is between elasticity fin lower ends external diameter and elasticity fin nature deployed condition maximum outside diameter.
In the present embodiment, alignment pin 2 directly is connected with the door-hinge cover, has increased by two elasticity fins 3 again on its two limits, the mounting plane that the end face of elasticity fin 3 and door-hinge overlap have one be slightly larger than door shell thickness the gap.
The course of work is: aim at the door-hinge hole on the door shell to it, directly inject door shell, beginning elasticity fin shrinks; The elasticity fin flicks at once after being inserted into the end, has withstood door shell, does not allow it moving up and down; And alignment pin has limited its rotation, and door-hinge cover itself has limited its moving all around.
Present embodiment adopts the spacing door-hinge cover of four-degree-of-freedom, as long as one inject its in door shell, has just limited immediately all around up and down and rotates four degree of freedom.
