The specific embodiment
To shown in Figure 5, the rotating shaft mechanism that the utility model is used for fridge-freezer comprises door pillar 21, locating rack as Fig. 3, and the inboard of door pillar 21 oneself bodies 2 is to evagination, and its two ends are equiped with first semiaxis 7 and second semiaxis 8 of coaxial arrangement respectively; Locating rack is an axle sleeve 5 of being located at the concave part 11 two ends place of casing 1, and by being rotatably assorted of first semiaxis 7, second semiaxis 8, axle sleeve 5, door pillar 21 rotational support are in locating rack, and the center of rotation of door pillar 21 is as the center of rotation of door body 2.Fig. 3 shows the concave part 11 that door pillar 21 rotates of dodging of the outer corner portion of being located at casing 1, and axle sleeve 5 is contained in the concave part 11 together with door pillar 21 and embeds the outer corner portion of casing 1, and the situation after the embedding illustrates with cutaway view in Fig. 5.
Continuation is referring to Fig. 5, and when door body 2 was in closed condition, the gasket of being located on the body 23 was divided into two parts of casing side and door side with the assembly of door body 2 and casing 1, wherein, the center of rotation of door body 2 is positioned at the casing side, that is, the center of rotation of door body 2 is positioned on the casing 1 and on the not gate body 2.In brief, door pillar 21 rotates in concave part 11, makes the center of rotation of door body 2 be positioned on the casing 1 thus.Beat as shown in Figure 5 in the process of opening door body 2, the distance between gasket 3 and the casing 1 is spacing minimum under the state of closing the door only.The situation that gasket and casing interference among Fig. 1 so can not occur.Owing to be subjected to the restriction of door pillar 21, the position of gasket 3 can be put into fixedly door pillar 21 position in addition, that is, door pillar 21 is arranged in the enclosing region of gasket 3, thereby prevents the situation generation that gasket opens the door and interferes.
Obviously, locating rack has numerous embodiments, a pair of axle sleeve 5 in being located at concave part 11, for example, when door pillar 21 is provided with sleeve member, when the axle part in this sleeve member and the casing 1 was rotatably assorted, locating rack can show as the minor axis of being located at a pair of coaxial arrangement in the concave part 11; Again for example, when door pillar 21 is a hollow structure, the hinged-support of a pair of coaxial arrangement is set in concave part 11, door pillar 21 can be rotationally connected with between two hinged-supports by axle spare, at this moment, locating rack shows as a pair of hinged-support with line boring.
Further, first semiaxis 7 of being located at door pillar 21 ends is set to elastic telescopic vertically, second semiaxis 8 is fixedlyed connected with the other end of door pillar 21, this moment, first semiaxis 7 and second semiaxis 8 constituted the rotating shaft of door pillar 21 jointly, when mounted, door body 2 two semiaxis 8 insert casing 1 bottom axle sleeve 5, then first semiaxis 7 are compressed, spring when treating a body 2 normal positions in first semiaxis 7 is bound to first semiaxis 7 in the upper shaft sleeve 5 of casing 1 automatically, finishes the installation of a body 2.
Except that the embodiment of above two semiaxis, rotating shaft also can be a bearing, for example, door body 21 is equipped with fixedly connected bearing, this bearing stretches out from door body 21 two ends, and in two axle sleeves in the concave part 11 one is made as elastic telescopic, thus also can be with the bearing rotational support in concave part 11.
In addition, fridge-freezer can be refrigerator or refrigerator-freezer, and refrigerator can be perpendicular opening the door (door body level is drawn back) or horizontal opening the door (the door body is upwards opened), and correspondingly, rotating shaft can vertically be arranged or lateral arrangement.
To sum up, in the rotating shaft mechanism of the present utility model, door pillar 21 rotational support are in locating rack, and door pillar 21 embeds in the outer corner portion of casing 1 together with locating rack, thereby the center of rotation of door pillar 21 is as the center of rotation of door body 2, and this center of rotation is positioned on the casing 1.
Further, rotating shaft mechanism of the present utility model also comprises the stop mechanism that opens the door, this stop mechanism that opens the door comprises the first backstop muscle 9, the second backstop muscle 9 ', wherein, the first backstop muscle 9 be located at the outside of door pillar 21 and vertically (with rotating shaft axially identical) extend, the second backstop muscle 9 is located in the concave part 11, when door body 2 is in limit opening position, the first backstop muscle 9 and the second backstop muscle 9 ' crash, with the maximum open position with limiting door body 2.The first backstop muscle 9, the second backstop muscle 9 ' can have numerous embodiments, for example all can be made as the bars that a plurality of disconnections are arranged.
In the rotating shaft mechanism of the present utility model, because the center of rotation of door body is positioned on the casing on the not gate body, this makes the door body be positioned at outside the enclosing region of door weather strip, the utility model has effectively been avoided in the switch door process situation of extruding gasket thus, and has improved that door does not close or the situation of cold draining.
And new appearance has been realized in the rotating shaft center of door body on casing.
Further, the backstop that crashes of the panel beating rotating shaft by independent stop part and casing in the prior art, contact area was big when the first backstop muscle in the utility model and the second backstop muscle crashed, and a door body opens the door, and can to bear strength bigger, and structure is more firm.
The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
