[0027] Refer to Figure 3 and 4 , the utility model provides a slide rail type drawer support device, including

[0028] door panel 1;

[0029] Two parallel slide rail frames 2 for supporting the drawer box 11;

[0030] Two door panel frames 21 are respectively connected to one of the slide rail frames 2, and both door panel frames 21 are fixedly connected to the door panel 1;

[0031] Support part 3, arranged between the slide rail frame 2 and the door panel frame 21; used to generate a thrust force on the door panel frame 21, reduce the torque at the connection part of the slide rail frame 2 and the door panel frame 21, and further reduce the wear amount therebetween;

[0032] As an implementation mode, a pin shaft 24 is inserted between the slide rail frame 2 and the door panel frame 21 of the utility model; the weight of the door panel 1 generates a torque at the pin shaft 24, so that the contact positions of the pin shaft with the slide rail frame 2 and the door panel frame 21 bear loads respectively. The support part 3 generates a horizontal thrust force to reduce the load at this contact position, also reduces the torque received at the pin shaft 24, and further reduces the wear amount at the contact position, and prolongs the service life of the pin shaft, the slide rail frame 2 and the door panel frame 21.

[0033] As an embodiment, the support part 3 of the utility model is fixedly connected to the slide rail frame 2, and the support part 3 also abuts against the door panel frame 21; by the support part 3, part of the load borne by the door panel frame 21 is transferred to the slide rail frame 2, increasing the load-bearing points, reducing the force between the slide rail frame 2 and the door panel frame 21, and reducing the wear amount therebetween.

[0034] Refer to Figure 5 , as an embodiment, the support part 3 of the utility model has a hollow cavity with an open end at one end; an elastic part 31 is arranged in the hollow cavity, and the elastic part 31 is also connected to a top cover 33 arranged at the open end of the hollow cavity; the support part 3 is fixed on the slide rail frame 2, and the top cover 33 abuts against the door panel frame 21.

[0035] Optionally, the support part 3 of the utility model can be fixed on the slide rail frame 2 by screws.

[0036] The elastic member 31 is in a compressed state and generates a thrust force on the door panel frame 21 through the top cover 33. During the process of pulling out or pushing back the drawer box 11, the door panel 1 bears the pulling force or the pushing-back force; during this process, the elastic member 31 is compressed or restored, reducing the impact force and wear amount between the slide rail frame 2, the door panel frame 21 and the pin shaft, and extending the fatigue life of the two.

[0037] The elastic member 31 of the present utility model is a spring or an elastic rubber strip;

[0038] Further, the elastic member 31 is a spring, and a positioning column 32 for fixing the spring is provided in the hollow cavity of the support member 3;

[0039] Preferably, a buffer pad is provided at the position where the top cover 33 contacts the door panel frame 21 to avoid hard contact between the two and reduce the impact force. Optionally, the buffer pad is a rubber pad or a silica gel pad.

[0040] The slide rail type drawer support device of the present utility model generates a thrust force on the door panel frame 21 by arranging a support member 3 between the slide rail frame 2 and the door panel frame 21, and then generates a reverse torque at the connection part between the slide rail frame 2 and the door panel frame 21. The torque of the gravity of the door panel 1 at this position is reduced, the load at the connection part between the slide rail frame 2 and the door panel frame 21 is reduced, and further the wear amount is reduced, and the service life of the two is extended.

[0041] See Figure 1 and Figure 2 , the present utility model also provides a refrigerator, including a box body 12, and at least one layer of drawer is installed in the box body 12; the drawer has the slide rail type drawer support device described above;
