[0028] Example

[0029] See also Figures 1 to 5 As shown:

[0030] The utility model provides a supporting device for preventing a refrigerator door from sagging, comprising a refrigerator body 10, a refrigerator door 20, a supporting portion 30 and a movable portion 40.

[0031] The support part 30 is installed on the refrigerator body 10, and an elastic member that can be extended and retracted in the vertical direction is provided on the support part 30; the movable part 40 is installed at the bottom of the refrigerator door 20, and is clamped with the support part 30, and the elastic member of the support part 30 is squeezed during the clamping process between the movable part 40 and the support part 30.

[0032] Through such an arrangement, the movable part 40 can be provided with an upward supporting force by the supporting part 30 after being engaged with the supporting part 30, so that the refrigerator door 20 is supported by the upward supporting force from the bottom, thereby preventing the refrigerator door 20 from falling during actual use, thereby making the use of the refrigerator door 20 more stable and extending the normal service life of the refrigerator door 20.

[0033] The support portion 30 is mainly composed of a vertical plate 31 , a clamping plate 32 and a rotating member.

[0034] During actual installation, one side of the vertical plate 31 is fitted and connected to the refrigerator body 10 by screws; there are two clamping plates 32, which are respectively vertically connected to the other side of the vertical plate 31, and a gap for installing the rotating part is provided between the two clamping plates 32; the two sides of the rotating part are respectively rotatably connected to the inner walls of the two clamping plates 32, and a clamping plate 36 is provided on the outside of the rotating part, and a torsion spring is provided at the connection between the rotating part and the clamping plate 32 to drive the rotating part to return to its original position; the movable part 40 is clamped with the clamping plate 36, and pushes the rotating part to rotate during the clamping process with the clamping plate 36.

[0035] By such arrangement, the movable part 40 can be engaged or separated with the clamping plate 36 during the opening and closing process of the refrigerator door 20. Due to the provision of the torsion spring, the rotating member can reset itself. At the same time, when the movable part 40 is engaged with the clamping plate 36, the clamping plate 36 can also provide an upward supporting force to the movable part 40.

[0036] The rotating member is mainly composed of a first rotating drum 33 and a second rotating drum 34 .

[0037] The movable part 40 includes a horizontal fixed plate 41, a triangular push plate 43 and a snap-on pin 44; the top of the horizontal fixed plate 41 is fitted and connected to the bottom of the refrigerator door 20; there are two triangular push plates 43, which are respectively vertically connected to one end of the bottom of the horizontal fixed plate 41; the two ends of the snap-on pin 44 are respectively vertically connected to the inner walls of the two triangular push plates 43, and the middle part of the snap-on pin 44 is snap-connected with the slot on the snap-on plate 36.

[0038] The two ends of the first rotating drum 33 are rotatably connected to the two clamping plates 32 respectively. The torsion spring is installed at the connection between the first rotating drum 33 and the clamping plates 32 to drive the first rotating drum 33 to rotate and then reset.

[0039] The second rotating drum 34 is sleeved on the first rotating drum 33 and fixedly connected thereto; the clamping plate 36 is vertically connected to the outer wall of the first rotating drum 33 .

[0040] Through such a configuration, the snap-in plate 36, under the push of the snap-in pin 44, drives the second rotating drum 34 and the first rotating drum 33 to rotate simultaneously until the refrigerator door 20 is completely closed, thereby satisfying the requirement of driving the snap-in pin 44 to move when the refrigerator door 20 is opened and closed, and making the snap-in and snap-out process between the snap-in pin 44 and the snap-in plate 36 smoother.

[0041] The first rotating drum 33 and the second rotating drum 34 are both hollow. The elastic member mainly comprises a support column 35, a return spring 351, a limit plate 37 and a support plate 38.

[0042] The first drum 33 and the second drum 34 are both provided with through holes through which the support column 35 passes, and the opening of the through hole of the second drum 34 is smaller than the diameter of the hole, so that a limiting groove is formed inside the through hole of the second drum 34 .

[0043] An annular limiting ring 352 is mounted on the support column 35, and the annular limiting ring 352 is fixedly connected to the support column 35. During actual installation, the annular limiting ring 352 is located in the limiting groove; the return spring 351 is mounted on the support column 35, the top of the return spring 351 abuts against the top inner wall of the limiting groove, and the bottom of the return spring 351 abuts against the annular limiting ring 352.

[0044] Through such an arrangement, when the bottom of the support column 35 is subjected to an upward thrust, the annular limit ring 352 and the support column 35 can be displaced upward at the same time, thereby compressing the return spring 351. When the upward thrust at the bottom of the support column 35 is released, the return spring 351 pushes the annular limit ring 352, thereby driving the support column 35 to reset.

[0045] There are two limiting plates 37 , which are respectively vertically connected to the vertical plates 31 , and the limiting plates 37 are provided with long strip limiting holes 371 along the vertical direction.

[0046] A first pin is provided at the bottom of the support plate 38, and the two ends of the first pin are respectively inserted into the long strip-shaped limiting holes 371 of the two limiting plates 37. A second pin is provided at the top of the support plate 38, and the two ends of the second pin are vertically connected to the inner walls of the two sides of the second rotating drum 34, and the second rotating drum 34 is provided with a movable hole for the support plate 38 to swing when the second rotating drum 34 rotates; the bottom of the support column 35 is in contact with the top of the support plate 38.

[0047] Through such a configuration, when the snap-in pin 44 pushes the snap-in plate 36 to drive the second rotating drum 34 to rotate, it simultaneously drives the top of the support plate 38 to deflect until the top of the support plate 38 forms abutment with the bottom of the support column 35, and at this time the snap-in connection between the snap-in pin 44 and the snap-in plate 36 is completed.

[0048] It also includes an annular ring 42 ; the annular ring 42 is closely connected to the other end of the bottom of the horizontal fixed plate 41 ; the top of the support column 35 is in contact with the annular ring 42 .

[0049] Similarly, when the engagement between the engaging pin 44 and the engaging plate 36 is released, the second rotating drum 34 is reset under the drive of the first rotating drum 33. At this time, the top of the supporting plate 38 is synchronously driven to deflect, so that the abutting connection between the top of the supporting plate 38 and the bottom of the supporting column 35 is released, and the supporting column 35 is reset under the drive of the reset spring 351, so that the abutting connection between the top of the supporting column 35 and the annular ring 42 is released. This completely releases the connection between the movable part 40 at the bottom of the refrigerator door 20 and the supporting part 30 on the refrigerator body 10, and does not affect the opening and closing of the refrigerator door 20.

[0050] It also includes an abutment pin 372, an abutment spring and an abutment base; the abutment base is fixed between the two limit plates 37; one end of the abutment pin 372 is sleeved in the abutment base and can slide in the horizontal direction of the abutment base, the other end of the abutment pin 372 abuts against one side of the support plate 38, and the abutment end of the abutment pin 372 and the support plate 38 is set in a bullet shape; the abutment spring is set in the abutment base and sleeved in the middle of the abutment pin 372. A circular arc groove is provided at the abutment point between the support plate 38 and the abutment pin 372.

[0051] With such an arrangement, when the abutment pin 372 abuts against the support plate 38 under the push of the abutment spring, the top of the support plate 38 abuts against the bottom of the support column 35 more stably.

[0052] The length of the clamping slot on the clamping plate 36 is the same as the maximum return circumference of the torsion spring.

[0053] It should be noted that if the embodiments of the present invention involve directional indications such as up, down, left, right, front, back, etc., then the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0054] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist.

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
