A door body assembly 100 and a refrigerator 600 of a refrigerator 600 according to an embodiment of the present invention will be described below with reference to FIGS.

As shown in FIGS. 1 to 6, a door body assembly 100 of a refrigerator 600 according to an embodiment of the present invention. The door body assembly 100 of the refrigerator 600 includes a door body 10, a hinge fixing plate 20, a hinge shaft 30, a boss 40, and a screw 50.

Specifically, as shown in FIGS. 1 to 6 , the hinge fixing plate 20 is spaced apart from the door body 10 , and the door body 10 is provided with a mounting groove 110 . The hinge shaft 30 is fixed on the hinge fixing plate 20, and one end of the hinge shaft 30 extends into the mounting groove 110. The hinge shaft 30 is provided with a first limiting portion 310 and a threaded through hole 320 extending therethrough along the axis. A second limiting portion 410 is disposed on the sleeve 40, and the sleeve 40 is located in the mounting slot 110. The sleeve 40 is disposed at one end of the hinge shaft 30. The first limiting portion 310 cooperates with the second limiting portion 410 to define The sleeve 40 is movable relative to the hinge shaft 30 in its axial direction. The screw 50 is threaded into the threaded through hole 320, and one end of the screw 50 passes through one end of the hinge shaft 30 and abuts against the sleeve 40.

For example, as shown in the example of FIG. 3, the door body 10 and the hinge fixing plate 20 may be spaced apart in the up and down direction (up and down direction as shown in FIG. 3), and the left end of the hinge fixing plate 20 may be attached to the casing of the refrigerator 600. 610 fixed connection. A hinge shaft 30 is provided on the hinge fixing plate 20, and the hinge shaft 30 extends in the up and down direction (up and down direction as shown in FIG. 3). The lower end of the door body 10 may be provided with a mounting groove 110. As shown in FIG. 3, the mounting groove 110 may be a cylindrical mounting groove 110.

The upper end of the hinge shaft 30 projects into the mounting groove 110, and the lower end of the hinge shaft 30 is fixedly coupled to the hinge fixing plate 20. The inside of the hinge shaft 30 is provided with a threaded through hole 320 which penetrates the hinge shaft 30 in the up and down direction (up and down direction as shown in FIG. 3), and the screw 50 is bored in the threaded through hole 320. A sleeve 40 matching the shape of the mounting groove 110 may be embedded in the mounting groove 110. The sleeve 40 has a downward opening, and the sleeve 40 is disposed above the hinge shaft 30, and the upper end of the screw 50 and the shaft Set 40 to offset. As shown in FIG. 5, a first limiting portion 310 may be disposed on the outer peripheral wall of the hinge shaft 30. Accordingly, a corresponding portion of the first limiting portion 310 may be disposed on the inner peripheral wall of the sleeve 40. The second limiting portion 410, the limit fit between the first limiting portion 310 and the second limiting portion 410 can make the sleeve 40 be along the axial direction of the hinge shaft 30 (ie, the up and down direction shown in FIG. 5) The movement and the relative rotation of the sleeve 40 and the hinge shaft 30 in the circumferential direction can be prevented.

It should be noted that the hinge fixing plate 20 is fixed on the casing 610 of the refrigerator 600, and the hinge shaft 30 is fixedly connected with the hinge fixing plate 20, so that the hinge shaft 30 and the hinge fixing plate 20 are always maintained with respect to the casing 610 of the refrigerator 600. Stationary state. The screw 50 is threaded into the threaded through hole 320 of the hinge shaft 30, and the hinge shaft 30 can be screwed with the screw 50, that is, the screw 50 can be rotated relative to the hinge shaft 30 when the screw 50 is rotated relative to the hinge shaft 30. The screw 50 is also moved relative to the hinge shaft 30 in its axial direction. For example, when the screw 50 rotates relative to the hinge shaft 30 (eg, the screw 50 rotates clockwise relative to the hinge shaft 30), the screw 50 moves downwardly relative to the hinge shaft 30 in its axial direction; when the screw 50 rotates relative to the hinge shaft 30 When the screw 50 is rotated counterclockwise with respect to the hinge shaft 30, the screw 50 is moved upward relative to the hinge shaft 30 in the axial direction thereof.

Since the screw 50 is movable relative to the hinge shaft 30 in its axial direction, the sleeve 40 engaged with the screw 50 can also move as the screw 50 moves. It should be noted that the first limiting portion 310 is disposed on the hinge shaft 30. The second limiting portion 410 is matched with the first limiting portion 310. The first limiting portion 310 is coupled to the first limiting portion 310. The limit fit between the second limiting portions 410 prevents relative rotation of the sleeve 40 and the hinge shaft 30 in the circumferential direction, so that the sleeve 40 can be oriented in the axial direction of the hinge shaft 30 (ie, as shown in FIG. 5). The up and down direction) moves. For example, as shown in FIG. 3, when the screw 50 moves upward, the screw 50 can drive the sleeve 40 to move upward, thereby driving the door body 10 to move upward; when the screw 50 moves downward, the door body 10 acts on its own gravity. The lower movement moves as the screw 50 moves.

Thereby, the elevation adjustment of the height of the door body 10 in the up and down direction can be achieved. Therefore, when the door body 10 of the refrigerator 600 is displaced in the up and down direction due to long-term use, or the size error caused by the production of the door body 10 causes the heights of the left and right door bodies 10 of the refrigerator 600 to be inconsistent, the refrigerator 600 can be adjusted. The door body assembly 100 conveniently adjusts the height of the door body 10 to maintain the overall appearance of the refrigerator 600.

According to the door assembly 100 of the refrigerator 600 according to the embodiment of the present invention, when the screw 50 is rotated, the screw 50 can be moved in the up and down direction, since the upper end of the screw 50 is offset from the sleeve 40 embedded in the mounting groove 110 of the door body 10. . Therefore, when the screw 50 moves in the up and down direction, the sleeve 40 and the door body 10 can be moved in the up and down direction, thereby realizing the height adjustment of the door body 10 in the up and down direction, the structure is simple, the operation is convenient, and the left and right doors of the refrigerator 600 are effectively overcome. The height of the body 10 does not affect the overall aesthetics of the refrigerator 600.

According to some embodiments of the present invention, one of the first limiting portion 310 and the second limiting portion 410 is a limiting groove 311 extending along the axis of the hinge shaft 30, and the other is adapted to the limiting groove 311. The limiting protrusion 411 is provided. In other words, the first limiting portion 310 can be formed as a limiting groove 311 extending along the axial direction of the hinge axis 30, and the second limiting portion 410 can be formed as a limiting convex corresponding to the limiting groove 311. From 411.

For example, as shown in the example of FIG. 5, on the outer peripheral wall of the hinge shaft 30, a limit groove 311 is provided along the axial direction of the hinge shaft 30 (i.e., the up and down direction shown in FIG. 5), and accordingly, A limiting protrusion 411 matching the limiting groove 311 is disposed on the inner peripheral wall of the sleeve 40, and the limiting protrusion 411 is along the axial direction of the sleeve 40 (ie, the up and down direction shown in FIG. 5) extend. Thus, when the sleeve 40 is disposed over the hinge shaft 30, the first limiting portion 310 and the second limiting portion 410 can define that the sleeve 40 can be along the axial direction of the hinge shaft 30 (ie, as shown in FIG. 5). The movement in the up and down direction is shown to move, and the relative rotation between the sleeve 40 and the hinge shaft 30 is prevented when the door body 10 is rotated. In order to prevent the rotation of the sleeve 40 when the door body 10 is rotated, the adjustment of the height of the door body 10 is caused.

In other embodiments of the present invention, the first limiting portion 310 may also be formed as a limiting protrusion 411 extending in the axial direction of the hinge shaft 30, and correspondingly, the second limiting portion 410 on the sleeve 40 The limiting groove 311 is formed to be matched with the limiting protrusion 411.

Further, the limiting recess 311 may be one, and the limiting protrusions 411 may be one or a plurality of spaced apart in the axial direction of the hinge shaft 30. That is, the limiting recess 311 may be one, and the limiting protrusion 411 may be formed as one corresponding to the limiting recess 311 or may be formed as multiple matching with the limiting recess 311. It can be understood that when the limiting groove 311 is one and the limiting protrusion 411 is plural, the plurality of limiting protrusions 411 are located in the same axial direction along the hinge axis 30, and the plurality of limiting protrusions The 411 are spaced apart along the axial direction of the hinge shaft 30.

For example, as shown in FIG. 6, a groove may be provided on the outer peripheral wall of the hinge shaft 30 in the axial direction (i.e., the up and down direction shown in Fig. 6), on the inner peripheral wall of the sleeve 40, along the Two limiting protrusions 411 are disposed in the same axial direction of the hinge shaft 30. The two limiting protrusions 411 can be respectively disposed at the upper end and the lower end of the inner wall of the sleeve 40. Of course, the limiting protrusion 411 can also be along A plurality of the hinge shafts 30 are spaced apart in the axial direction. Thereby, the processing of the stopper groove 311 and the stopper projection 411 is facilitated.

In other embodiments of the present invention, the limiting recesses 311 may be plural, and the plurality of limiting recesses 311 are spaced apart in the circumferential direction of the hinge shaft 30. The limiting protrusions 411 may be a plurality of, and the plurality of limiting protrusions 411 are in one-to-one correspondence with the plurality of limiting grooves 311. For example, as shown in the examples in FIGS. 4 and 5, on the outer peripheral wall of the hinge shaft 30, two limit positions are arranged along the axial direction of the hinge shaft 30 (i.e., the up and down direction shown in FIGS. 4 and 5). The groove 311 and the two limiting grooves 311 are symmetrically arranged. Correspondingly, two limiting projections 411 extending in the axial direction of the hinge shaft 30 are disposed symmetrically on the inner peripheral wall of the sleeve 40. Thus, by the limit fit between the limiting groove 311 and the limiting protrusion 411, it can be further defined that only the axial direction can occur between the sleeve 40 and the hinge shaft 30 (ie, as shown in FIGS. 4 and 5). Relative movement of the up and down direction) prevents relative rotation between the sleeve 40 and the hinge shaft 30, thereby improving the door group The piece 100 adjusts the reliability of the height of the door body 10. Certainly, the number of the limiting recesses 311 may also be multiple. Accordingly, the limiting protrusions 411 are plural, and the limiting protrusions 411 and the limiting recesses 311 are matched in one-to-one correspondence.

According to some embodiments of the invention, the end faces of the free ends 4111 of the limiting projections 411 are planar or curved faces. It should be noted that the free end 4111 of the limiting protrusion 411 refers to the other end opposite to the end of the sleeve 40 fixed to the limiting protrusion 411. For example, as shown in the example in FIG. 5, two limit projections 411 are provided symmetrically on the inner peripheral wall of the boss 40 in the axial direction of the boss 40 (i.e., the up and down direction shown in FIG. 5). One end of the limiting protrusion 411 is fixed on the inner peripheral wall of the sleeve 40, and the other end of the limiting protrusion 411 is the free end 4111 of the limiting protrusion 411. The free end 4111 of the limiting protrusion 411 can be arranged either as a flat surface or as a curved surface. As shown in FIG. 5, the free end 4111 of the limiting projection 411 is disposed in a plane, and a chamfer is provided between the free end 4111 and the side wall. Thereby, the manufacturing of the stopper projection 411 is facilitated, so that the production cost can be reduced.

The two positioning portions 510 are adapted. For example, as shown in the example of FIG. 5, the sleeve 40 is sleeved over the hinge shaft 30, and the screw 50 is threaded through the threaded through hole 320 of the hinge shaft 30, the upper end of the screw 50 and the inside of the sleeve 40. The top wall is offset. A first positioning portion 420 may be disposed at a position opposite to the screw 50 on the inner top wall of the sleeve 40. Accordingly, the upper end of the screw 50 may be provided with a second positioning portion 510 adapted to the first positioning portion 420. . Thereby, the positioning assembly between the screw 50 and the sleeve 40 can be facilitated during the assembly process of the door body assembly 100 to improve assembly efficiency.

Further, one of the first positioning portion 420 and the second positioning portion 510 is a positioning protrusion 421, and the other is a positioning groove 511. For example, as shown in the example of FIG. 3, a cylindrical positioning projection 421 extending downward (up and down direction as shown in FIG. 3) may be disposed at a position opposite to the screw 50 on the inner top wall of the boss 40. Accordingly, a cylindrical positioning groove 511 which is recessed downward is provided at the upper end of the screw 50. The sleeve 40 and the screw 50 can be positioned by the positioning protrusion 421 and the positioning groove 511 to facilitate assembly of the door assembly 100. It is to be understood that a proper gap may be provided between the cylindrical positioning protrusion 421 and the cylindrical positioning groove 511 to facilitate relative rotation of the upper end of the screw 50 and the sleeve 40 to facilitate adjustment of the height of the door body 10.

In some embodiments of the present invention, the end face of the other end of the screw 50 is provided with an adjustment groove 520 having a "+" shape or a "-" shape. For example, as shown in the example of FIG. 5, an adjustment groove 520 is provided at the lower end of the screw 50, and the shape of the adjustment groove 520 is "+". In other embodiments of the present invention, the adjustment groove 520 may also be set to " -"shape. Therefore, the screw 50 can be twisted from the lower end of the screw 50 by using a cross-shaped or a flat-shaped screwdriver to realize the vertical movement of the screw 50, thereby moving the door body 10 of the sleeve 40 in the up and down direction to adjust the height of the door body 10. Easy to operate and flexible to adjust.

According to some embodiments of the present invention, the other end of the hinge shaft 30 may have an annular mounting groove 330 in which the hinge fixing plate 20 is snapped. For example, as shown in the example in FIG. 3, the lower end of the hinge shaft 30 may be provided with The annular mounting groove 330 has an annular mounting groove 330 having a radial radius smaller than a radial radius at the remaining position at the lower end of the hinge shaft 30, and the height of the annular mounting groove 330 in the up and down direction (up and down direction as shown in FIG. 3) The thickness at the position where the hinge fixing plate 20 is fitted with the hinge shaft 30 (i.e., the thickness of the hinge fixing plate 20 shown in FIG. 3 in the up and down direction) is equal, so that the hinge shaft 30 can be stably fixed to the hinge fixing plate 20, preventing the hinge from being hinged. Relative movement between the shaft 30 and the hinge fixing plate 20 occurs. It is to be understood that the hinge fixing plate 20 may include two pieces that are divided along the axial direction of the hinge shaft 30, and the two hinge fixing plates 20 abut the fitting holes of the hinge shaft 30 to be matched with the annular mounting groove 330, thereby The hinge fixing plate 20 is snapped into the annular mounting groove 330 of the hinge shaft 30.

In other embodiments of the present invention, the hinge shaft 30 can also be fixedly mounted on the hinge fixing plate 20 by a riveted joint, whereby the stability of the connection between the hinge shaft 30 and the hinge fixing plate 20 can be enhanced, and the hinge shaft can be prevented. A relative movement occurs between the 30 and the hinge fixing plate 20. Of course, the hinge shaft 30 and the hinge fixing plate 20 can also be fixedly assembled by welding or other connection.

The door body assembly 100 of the refrigerator 600 according to an embodiment of the present invention will be described in detail below with reference to FIGS. 1 through 6 in a specific embodiment. It is to be understood that the following description is only illustrative and not restrictive.

As shown in FIG. 3, the lower end of the hinge fixing plate 20 is provided with an annular mounting groove 330, and the hinge fixing plate 20 is firmly seated in the annular mounting groove 330. A cylindrical mounting groove 110 is provided below the door body 10, and an upper end of the hinge shaft 30 projects into the mounting groove 110.

As shown in FIG. 4 and FIG. 5, the outer peripheral wall of the hinge shaft 30 is symmetrically disposed with two limiting grooves 311 extending in the axial direction of the hinge shaft 30 (ie, the up and down direction shown in FIG. 5) at the hinge. A threaded through hole 320 is formed through the inside of the shaft 30. The screw 50 is threaded into the interior of the hinge shaft 30 by a threaded connection with the threaded through hole 320. As shown in FIG. 3, a sleeve 40 adapted to the shape of the mounting groove 110 is disposed in the mounting groove 110, and the sleeve 40 is sleeved over the hinge shaft 30. As shown in FIG. 4 and FIG. 5, the inner peripheral wall of the sleeve 40 is symmetrically disposed with two limiting protrusions 411. The end surface of the free end 4111 of the limiting protrusion 411 is a flat surface, and the limiting protrusion 411 and the limiting position are arranged. The groove 311 is engaged with the limit, and the movement between the sleeve 40 and the hinge shaft 30 is defined only in the axial direction of the hinge shaft 30 (i.e., the up and down direction shown in Figs. 4 and 5). The upper end of the screw 50 is provided with a cylindrical positioning groove 511 (as shown in FIG. 3). The inner top wall of the sleeve 40 is provided with a downwardly extending cylindrical positioning protrusion 421 through which the screw 50 passes.

Due to the hinge shaft 30 Fixed to the hinge fixing plate 20, the hinge fixing plate 20 is fixedly coupled to the housing 610 of the refrigerator 600, and therefore, the hinge shaft 30 and the hinge fixing plate 20 are in a stationary state with respect to the housing 610 of the refrigerator 600. The screw 50 is threaded into the threaded through hole 320 of the hinge shaft 30, and the hinge shaft 30 can be screwed with the screw 50, that is, the screw 50 can be rotated relative to the hinge shaft 30 when the screw 50 is rotated relative to the hinge shaft 30. The screw 50 is also moved relative to the hinge shaft 30 in its axial direction. For example, when the screw 50 is rotated relative to the hinge shaft 30 (eg, the screw 50 is rotated clockwise relative to the hinge shaft 30), the screw 50 is moved downward relative to the hinge shaft 30 in its axial direction; when the screw 50 is relative to the hinge shaft 30 When the rotation (for example, the screw 50 rotates counterclockwise with respect to the hinge shaft 30), the screw 50 moves upward in the axial direction thereof relative to the hinge shaft 30.

Since the screw 50 is movable relative to the hinge shaft 30 in its axial direction, the sleeve 40 that matches the screw 50 can also move with the movement of the screw 50. It should be noted that the first limiting portion 310 is disposed on the hinge shaft 30. The second limiting portion 410 is matched with the first limiting portion 310. The first limiting portion 310 is coupled to the first limiting portion 310. The cooperation between the second limiting portions 410 prevents relative rotation of the sleeve 40 and the hinge shaft 30 in the circumferential direction, so that the sleeve 40 can be oriented in the axial direction of the hinge shaft 30 (ie, as shown in FIG. 5 Direction) move. For example, as shown in FIG. 3, when the screw moves upward, the screw 50 can drive the sleeve 40 to move upward, thereby driving the door body 10 to move upward; when the screw 50 moves downward, the door body 10 is under the action of its own gravity. The screw 50 moves downward as the screw 50 moves.

A refrigerator 600 according to an embodiment of the present invention includes the door body assembly 100 of the refrigerator 600 described above.

According to the refrigerator 600 of the embodiment of the present invention, by rotating the screw 50 of the door assembly 100, the screw 50 can be moved in the up and down direction when the screw 50 rotates, since the upper end of the screw 50 abuts against the sleeve 40 embedded in the mounting groove 110 of the door body 10. . Therefore, when the screw 50 moves in the up and down direction, the sleeve 40 and the door body 10 can be moved in the up and down direction, thereby realizing the height adjustment of the door body 10 in the up and down direction, the structure is simple, the operation is convenient, and the left and right doors of the refrigerator 600 are effectively overcome. The height of the body 10 does not affect the overall aesthetics of the refrigerator 600.
