[0086] With reference to Figure 6 , Figure 8 and Figure 11 In some embodiments of the present application, the fixing member 400 is further provided with two plug-in parts 420 close to one end of the rear wall of the inner container 110, the two plug-in parts 420 are arranged at intervals along the width direction of the fixing member 400, and the corresponding positions of the bottom of the guide rail support 300 are provided with plug-in slots 320, and the plug-in parts 420 are connected to the plug-in slots 320.

[0087] In some embodiments of the present application, each plug-in part 420 comprises a plug-in vertical part 421 and a plug-in horizontal part 422, each plug-in vertical part 421 extends upwards along a direction perpendicular to the fixing member 400, and each plug-in horizontal part 422 extends towards each other, the plug-in slots 320 are formed with a matching horizontal part 321, and the plug-in horizontal part 422 is connected above the corresponding matching horizontal part 321.

[0088] The connection of the insertion part 420 and the insertion slot 320 facilitates positioning of the guide rail 113 support part during installation, and cooperates with the horizontal part 321 to limit the displacement of the insertion horizontal part 422 in the vertical direction, thereby improving the connection stability of the track support.

[0089] In some embodiments of the present application, an inclined section 423 is formed on the insertion horizontal part 422, and the inclined section 423 is located at one end of the insertion horizontal part 422 close to the door body.

[0090] The inclined section 423 is inclined upward in a direction away from the rear wall of the inner container 110, and the horizontal part 321 is formed with a contoured surface cooperating with the inclined section 423.

[0091] The inclined section 423 and the contoured surface cooperate to install the one end of the guide rail support part 300 provided with the insertion slot 320 in a downward direction, the inclined section 423 is connected to the horizontal part 321 along the contoured surface, and then the other end of the guide rail 113 support end is connected to the buckle part 410 through the clamping jaw 311.

[0092] The two ends of the insertion slot 320 are respectively formed with limiting end faces, and the insertion horizontal part 422 is connected to the corresponding insertion horizontal part 422 in the upward direction and positioned between the two limiting end faces.

[0093] In some embodiments of the present application, a support seat 360 is formed at the bottom of the guide rail support part 300, and the insertion slot 320 is formed on the support seat 360.

[0094] With reference to Figure 9 , the support seat 360 is further provided with an avoiding part 361, the clamping jaw 311 extends downward at the corresponding position of the avoiding part 361, the buckle upright part 411 is further provided with a positioning bend 413 extending in opposite directions, the size of the positioning bend 413 is matched with the avoiding part 361, and the positioning bend 413 and the buckle upright part 411 are connected into the corresponding avoiding part 361 in the clamping and buckling state of the clamping jaw 311 and the buckle protrusion 412.

[0095] The fixing part 400 is fixed on the bottom wall of the inner container 110 by means of adhesive, the bottom wall is pre-formed with a downward extending fixing recess 120, and the support seat 360 is located in the fixing recess 120.

[0096] In some embodiments of the present application, with reference again to Figure 8 , the circumferential side of the fixing part 400 is formed with an upward extending protection upright part 430, and the protection upright part 430 and the fixing part 400 surround a fixed position with an opening upward, and the support seat 360 is arranged in the fixed position.

[0097] In the installed state, the upper surface of the support seat 360 is flush with the bottom wall of the inner container 110, which is convenient for cleaning and better in appearance.

[0098] In some embodiments, a set of buckle assemblies and a plug-in part 420 are arranged along the length direction of the fixing part 400. During installation, first, the rail support part 300 is lifted at the end close to the door body, so that the matching horizontal part 321 is inserted into the lower side of the plug-in horizontal part 422 from front to back. When the plug-in horizontal part 422 cannot be inserted forward, it indicates that the connection between the plug-in horizontal part 422 and the matching horizontal part 321 is in place.

[0099] Then, the end of the rail support part 300 close to the door body is rotated from top to bottom, so that the pawl 311 gradually contacts the buckle protrusion 412. Under the action of the buckle protrusion 412, the pawl 311 is retracted, and when the clamping protrusion 312 moves to the lower side of the buckle protrusion 412, the pawl 311 and the clamping protrusion 312 expand outward under the restoring force of themselves. The clamping protrusion 312 is connected to the lower side of the buckle protrusion 412, realizing the buckle connection between the rail support part 300 and the fixing part 400. The plug-in part 420 cooperates with the buckle assembly to limit the front-back, left-right, and up-down six degrees of freedom of the rail support part 300, and plays a role in fixing the rail 113.

[0100] When unlocking, the auxiliary tool is used to apply force from the outside to the middle of the pawl 311, so that the clamping protrusion 312 on the pawl 311 is separated from the buckle protrusion 412. Then, the front side of the rail support part 300 is lifted upward, and then pulled obliquely upward, so that the matching horizontal part 321 is separated from the plug-in horizontal part 422, and the rail support part 300 is disassembled.

[0101] Compared with the traditional rail support part 300 which is connected by a fastening screw or other fixing mode, the buckle connection mode is beneficial to simplify the assembly process, improve the production efficiency, ensure the integrity of the inner container 110, avoid the loss of cold energy from the connection hole position in the refrigeration chamber 101, and improve the refrigeration effect.

[0102] In some embodiments of the present application, referring again to Figure 6 , the two sides of the rail support part 300 are formed with outwardly extending connecting shafts, which are located at the end of the rail support part 300 close to the door body. The connecting shafts are rotatably connected with the roller part 130. Figure 12 , the side of the drawer part 200 in contact with the rail support part 300 is formed with a pulling cross beam 220, and the roller part 130 is rollingly connected below the pulling cross beam 220.

[0103] The pulling cross beam 220 extends along the depth direction of the inner container 110. When the user pushes and pulls the drawer part 200, the pulling cross beam 220 moves forward and backward relative to the roller part 130. The rollingly connected roller part 130 and the pulling cross beam 220 can reduce the frictional force during the pushing and pulling of the drawer part 200, and save more labor.

[0104] The drawer beam 220 has a downwardly extending limiting end 221 near the rear wall of the inner liner 110, which is used to limit the maximum pull-out position of the drawer component 200.

[0105] Refer again Figure 6 The guide rail support 300 is provided with positioning recesses 330 on both sides, and positioning protrusions 230 are provided at corresponding positions on both sides of the drawer 200. The circumferential surface of the positioning protrusions 230 is an arc structure. During the process of pulling out the drawer 200, the positioning protrusions 230 move along the positioning recesses 330.

[0106] In some embodiments of this application, the end of the guide rail support 300 away from the door body is also provided with a vibration damping part 140, which is used to reduce the collision between the drawer 200 and the guide rail support 300 when the drawer is pushed in.

[0107] The vibration damping part 140 is specifically located at the end of the positioning recess 330. When the drawer part 200 is pushed inward to the innermost position, the positioning protrusion 230 contacts the vibration damping part 140. The vibration damping part 140 can buffer the drawer part 200 to prevent the drawer part 200 from colliding with the guide rail support 300 or the inner liner 110, causing noise and affecting the service life of the components.

[0108] In other embodiments, a limiting edge 340 is provided at one end of the guide rail 113 support near the door body. The limiting edge 340 extends to both sides along the guide rail 113 support.
