Detailed description of the invention
For enabling above-mentioned purpose of the present utility model, feature and advantage more become apparent, and are described in detail specific embodiment of the utility model below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the storage assembly in the utility model embodiment.Fig. 2 is the partial structurtes schematic diagram of the storage assembly in Fig. 1; Fig. 3 is the structural representation of the connector in Fig. 1.Fig. 4 is the structural representation of the refrigerator of the storage assembly comprised in Fig. 1.
Shown in Fig. 3, this storage assembly 2 comprises:
There is the housing 20 of storeroom 20a, being threadedly connected to the connector 21 of housing 20 by rotating along first direction, and in order to prevent connector 21 after being tightened in housing 20 along the position limiting structure 22 that the second direction contrary with first direction rotates.
Below each parts are introduced respectively.
With reference to shown in Fig. 1, housing 20 can comprise the enclosure body 201 limiting storeroom 20a and the upper cover plate 202 being fixed on enclosure body 201.In other embodiment, housing 20 also only can comprise the enclosure body 201 limiting storeroom 20a, or comprises outside enclosure body 201, upper cover plate 202, also comprises other parts.
Storeroom 20a can be vacuum storage compartment, vacuum storage environment is provided, also can for being filled with the storeroom of the character inactive gas such as nitrogen, above-mentioned two kinds of storeroom 20a reduce the oxygen content in storage ambient, be conducive to reducing bacterial reproduction speed, extend storage time.In other embodiment, the controlled atmosphere room of other types such as all right humid control storeroom.
Connector 21, for vacuum storage compartment 20a, it can for being provided with the valve gap of air extraction connector, and this air extraction connector is used for being connected with vavuum pump flexible pipe.In other embodiment, for inactive gas storeroom 20a, connector 21 can be the lid or pipe joint that are connected with the interface of this inactive gas storeroom 20a.
Connector 21, screwed by screw thread forward and be connected to housing 20, it is first direction (solid arrow in corresponding diagram 2) that this forward screws direction, correspondingly, the opposite direction second direction of this first direction is the oppositely loosening direction (dotted arrow in corresponding diagram 2) of connector 21.
With reference to shown in Fig. 1 and Fig. 2, position limiting structure 22, comprises from the jut 221 of the outside projection of connector 21 and the position-arresting part 222 being positioned at housing 20.When jut 221 reversely rotates, interfere with position-arresting part 222, thus stop the reverse rotation of jut 221, avoid connector 21 to loosen.In other embodiment, jut 221 also can be arranged on the housing 20, and position-arresting part 222 is arranged on connector 21.
With reference to shown in Fig. 2, in specific implementation process, jut 221 can comprise the shell fragment 223 from the outside projection of connector 21, and the free end of shell fragment 223 has boss 223a, and this boss 223a is used for offseting with position-arresting part 222.At connector 21 towards screwing in the rotation process of direction, boss 223a automatically can take advantage of a situation by the elasticity of shell fragment 223 and cross housing 20, or people is for pulling shell fragment 223, makes boss 223a cross housing 20; At connector 21 towards in the counter rotation of loosening direction, the shell fragment 223 being in free state can make boss 223a and position-arresting part 222 interfere, and limits its continuation and rotates towards loosening direction.
With reference to shown in Fig. 3, boss 223a, particularly, has outer peripheral face that is cylindrical or elliptical cylinder-shape.Relative to square or other there is the outer peripheral face of rib, arc-shaped circumference face can reduce the probability of other component interference on itself and path in the rotary course of jut 221 with connector 21.
With reference to shown in Fig. 2, position-arresting part 222, can by enclosure body 201, and the subregion of such as rear wall is served as, and also can by upper cover plate 202, such as, descend the subregion of flange to serve as.Be understandable that, have the boss 223a of the outer peripheral face of cylindrical or elliptical cylinder-shape and planar wall against time be linear contact lay.For strengthening limit effect, at housing 20, the stopper slot 224 enclosure body 201 being arranged there is curved wall can be specially.Be understandable that, curved wall defines position-arresting part 222, has changed linear contact lay into face contact.In other embodiment, stopper slot 224 also can be arranged on upper cover plate 202.
Still with reference to shown in Fig. 2, for making boss 223a easily pass through in connector 21 forward screwing operations, the adjoining outer walls of housing 20, at least part of region of adjoining outer walls of enclosure body 201 connects with the transitional surface 203 of depression in the present embodiment.At connector 21 along when rotating forward, this transitional surface 203 is crossed for boss 223a.In other embodiment, transitional surface 203 also can be arranged on upper cover plate 202.
For making boss 223a in forward screwing operations, easily by housing 20, and when oppositely loosening, interfere with housing 20 outer wall, with reference to shown in Fig. 3, the guiding face 223b of the free end of boss 223a screws direction at forward and is inclined upwardly.Can find out, be arranged by this mode of being inclined upwardly, boss 223a is different to the thickness of downward-extension, specifically comprises Bao Chu and Hou Chu.The end in the corresponding face that is inclined upwardly, thin place, not easily interferes with housing 20 outer wall in connector 21 forward screwing operations; Thick place make when connector 21 rotates backward and housing 20 outer wall against, be difficult to be rotated further again.
In addition, still with reference to shown in Fig. 3, guiding face 223b is convex outward, relative to plane or inner sunken face, guiding face 223b can be avoided to have corner angle, reduces the frictional force in boss 223a rotation process.
Can find out, with reference to shown in Fig. 2, connector 21 is with after housing 20 screw thread screws and is connected, boss 223a on it is against in stopper slot 224 on the housing 20, be equivalent to connector 21 is provided with a self-locking mechanism, stop connector 21 to rotate backward, because the storeroom 20a in above-described embodiment is controlled atmosphere room, thus self-locking mechanism can improve the air-tightness between connector 21 and housing 20.
In other embodiment, this storeroom 20a also can for being in communication with the outside, the storeroom used under normal atmospheric pressure (i.e. 1 atmospheric pressure).Be understandable that, for this kind of storeroom, self-locking mechanism can improve the reliability that connector 21 is connected with housing 20.
With reference to shown in Fig. 4, based on above-mentioned storage assembly 2, the utility model additionally provides a kind of refrigerator 1 comprising above-mentioned storage assembly 2.For vacuum storage compartment 20a, the air-tightness between connector 21 and vacuum storage compartment 20a improves, and can avoid vacuum environment Leakage Gas, improves hoarding effect, also can avoid vavuum pump frequent starting simultaneously, is conducive to the energy consumption reducing refrigerator 1.For character inactive gas storeroom 20a such as nitrogen, air-tightness between connector 21 and inactive gas storeroom 20a improves, inactive gas can be avoided to leak, improve hoarding effect, also can avoid, frequently to storeroom inflation, being conducive to the service life extending inactive gas generation device simultaneously.
Although the utility model discloses as above, the utility model is not defined in this.Any those skilled in the art, not departing from spirit and scope of the present utility model, all can make various changes or modifications, and therefore protection domain of the present utility model should be as the criterion with claim limited range.
