[0097] In some embodiments, as shown in Figures 1 to 3 The refrigerator 100 further includes a guide rail 40, which is slidably connected to the fixed rail in the storage compartment and connected to the drawer door 30, so that the drawer door 30 can be pulled and slid relative to the cabinet 10 to open and close the access opening.

[0098] Optionally, the guide rail 40 is usually provided with two, which are respectively located at both sides of the drawer door 30 in the width direction of the cabinet 10. In this way, the stability of the installation of the drawer door 30 can be ensured, and the middle position can be avoided to place a storage container, such as a drawer box 50.

[0099] As shown in Figures 1 to 3 The drawer door 30 provided by the embodiments of the present application includes a door body 31, which is in contact with the cabinet 10 to close the access opening.

[0100] Optionally, the edge of the door body 31 is provided with a door sealing member 60 to improve the sealing performance when closing the access opening.

[0101] In some embodiments, as shown in Figure 3 and Figure 4 The drawer door 30 includes a door panel 32, which is arranged along the length direction of the cabinet (corresponding to the X-axis direction in the drawings) with the door body 31. The door panel 32 is located outside the door body 31 and is an appearance part of the drawer door.

[0102] In some embodiments, as shown in Figures 3 to 5As shown, the drawer door 30 includes a door frame 33, which is located at the edge of the door core 31 and the door panel 32. The door core 31, the door panel 32, and the door frame 33 together enclose a receiving cavity 30a. An insulation structure can be formed in the receiving cavity 30a, such as by foaming to form an insulation layer, to insulate the storage room and improve the insulation and heat insulation effect of the drawer door 30. That is, the receiving cavity 30a is used to hold foam material. By filling the receiving cavity 30a with foam material, the drawer door 30 can have insulation and heat insulation properties.

[0103] Optionally, the door frame 33 can be glued to the door panel 32, or the door frame 33 can form a receiving groove, and the door panel 32 can be interference-fitted into the receiving groove; in this way, there is no need to set a fixing structure on the door panel 32, which helps to ensure the appearance of the door panel 32. The door frame 33 and the door core 31 can be snapped together, glued, etc.

[0104] An example, such as Figure 5 As shown, the door frame 33 can be ring-shaped, surrounding the edges of the door core 31 and the door panel 32. The door frame 33 can be an integral structure or a separate structure. For example, the door frame 33 may include a first side frame 331, a second side frame 332, a first end cap 333, and a second end cap 334. The side frames of the first side frame 331 and the second side frame 332 are along the width direction of the housing (corresponding to...). Figure 5 The first end cap 333 and the second end cap 334 are arranged opposite and spaced apart along the Y-axis direction of the housing, and are along the height direction of the housing (corresponding to the height direction of the housing). Figure 5 The two side frames (in the Z-axis direction) are arranged opposite to each other and spaced apart, and the first end cap 333 is connected to the first side frame 331 and the second side frame 332, and the second end cap 334 is connected to the first side frame 331 and the second side frame 332. For example, the first end cap 333 is connected to the top of the first side frame 331 and the second side frame 332 in the height direction of the box, and the second end cap 334 is connected to the bottom of the first side frame 331 and the second side frame 332 in the height direction of the box.

[0105] Another example, such as Figure 6 As shown, the door panel 32 is in the width direction of the cabinet (corresponding to) Figure 6 Side panels 32a can be formed on both sides of the door frame 33 (in the Y-axis direction) by bending towards the door liner 31. The door frame 33 may include a first end cover 333 and a second end cover 334. The first end cover 333 and the second end cover 334 are along the height direction of the box body (corresponding to the height direction of the box body). Figure 6 The two side plates 32a are arranged opposite each other and spaced apart in the Z-axis direction, and the first end cover 333 is connected between the two side plates 32a and the second end cover 334 is connected between the two side plates 32a. For example, the first end cover 333 is connected to the top of the two side plates 32a in the height direction of the box, and the second end cover 334 is connected to the bottom of the two side plates 32a in the height direction of the box.

[0106] Please refer to Figures 4 to 6 The drawer door 30 provided by the embodiments of the present application comprises a fixing seat 34 arranged in the accommodating cavity 30a, and the two ends of the fixing seat 34 in the preset direction are connected with the door frame 33, the fixing seat 34 is connected with the guide rail 40, so as to realize the fixed connection between the guide rail 40 and the drawer door 30.

[0110] In some embodiments, as shown in Figures 6 to 9 The side of the fixing seat 34 facing the door body 31 is provided with a first positioning part 34a, and the guide rail 40 is provided with a second positioning part 41 opposite to the first positioning part 34a, one of the first positioning part 34a and the second positioning part 41 is a positioning column, and the other of the first positioning part 34a and the second positioning part 41 is a positioning hole, for example, the side of the fixing seat 34 facing the door body 31 is provided with a positioning column, the guide rail 40 is provided with a positioning hole opposite to the positioning column, and the door body 31 is provided with a first through hole 311 for the positioning column to pass through, so that the positioning column can be exposed to the door body 31, and the positioning column and the positioning hole on the guide rail 40 can be aligned and installed.

[0111] Optionally, the first positioning part 34a is provided in multiple, and the multiple first positioning parts 34a are arranged in a spaced manner. Correspondingly, the second positioning part 41 on the guide rail 40 and the first through hole 311 on the door body 31 are both provided in multiple and arranged one by one corresponding to the first positioning part 34a, so as to further improve the firmness of the installation of the guide rail 40.

The connecting hole 42 can be a through hole with threads on the hole wall surface, or a through hole without threads on the hole wall surface.

[0113] Optionally, a plurality of threaded holes 34b are provided, and the plurality of threaded holes 34b are arranged at intervals. Correspondingly, the connecting holes 42 on the guide rail 40 and the second through holes 312 on the door shell 31 are each provided with a plurality of holes and are arranged one-to-one corresponding to the threaded holes 34b, thereby facilitating the improvement of the firmness of the installation of the guide rail 40.

[0114] Please refer to Figure 9 and Figure 10 The fixing seat 34 provided by the embodiments of the present application includes a first seat body 341 and a second seat body 342, one end of the first seat body 341 in a preset direction is connected with the door frame 33, one end of the second seat body 342 in the preset direction is connected with the door frame 33, the second seat body 342 and / or the first seat body 341 is connected with the guide rail 40, so as to realize the connection of the fixing seat 34 and the guide rail 40, and the second seat body 342 is movably connected with the first seat body 341, and the second seat body 342 can move along the preset direction relative to the first seat body 341, so as to adjust the overall size of the fixing seat 34 in the preset direction.

[0115] When the preset direction is configured as the height direction of the cabinet (corresponding to the Z-axis direction in Figure 10 ), the second seat body 342 can move along the height direction of the cabinet relative to the first seat body 341, so as to adjust the overall height of the fixing seat 34 in the height direction of the cabinet, so that the fixing seat 34 can be adapted to door frames 33 of different heights, thereby improving the versatility of the fixing seat 34. For refrigerator products of different sizes, the mold of the fixing seat 34 does not need to be changed, and only the length of the fixing seat 34 in the height direction of the cabinet needs to be changed by moving the second seat body 342 and the first seat body 341 in the height direction of the cabinet, so that the fixing seat 34 can be applied to refrigerator drawer doors 30 of different heights, thereby facilitating the improvement of the production efficiency of the refrigerator and the reduction of the development cost and production cost of the refrigerator.

[0116] At this time, when there are two fixed seats 34, the two fixed seats 34 are arranged at intervals along the width direction of the box, and the two fixed seats 34 are respectively connected to the door frame 33 at both ends in the height direction of the box. The first seat body 341 of the two fixed seats 34 is fixedly connected to the ends of the two guide rails 40, or the second seat body 342 of the two fixed seats 34 is fixedly connected to the ends of the two guide rails 40.

[0117] When the preset direction is configured as the width direction of the box, the fixing seat 34 extends laterally (corresponding to the Y-axis direction in the attached figure). There is one fixing seat 34. The two ends of the fixing seat 34 in the width direction of the box are respectively connected to the door frame 33, and the two ends of the fixing seat 34 in the width direction of the box are respectively fixedly connected to the ends of the two guide rails 40.

[0118] When the preset direction is configured as the width direction of the box (corresponding to...) Figure 10 When the second seat 342 moves relative to the first seat 341 along the width direction of the cabinet (in the Y-axis direction), the overall width of the fixed seat 34 in the width direction of the cabinet can be adjusted so that the fixed seat 34 can be adapted to door frames 33 of different widths, thereby improving the versatility of the fixed seat 34. For refrigerator products of different sizes, there is no need to change the mold of the fixed seat 34. It is only necessary to move the second seat 342 and the first seat 341 in the width direction of the cabinet to change the length of the fixed seat 34 in the width direction of the cabinet, so that it can be adapted to refrigerator drawer doors 30 of different widths. This is conducive to improving the production efficiency of the refrigerator and reducing the development and production costs of the refrigerator.

[0119] At this time, when there is one fixed seat 34, the two ends of the fixed seat 34 in the width direction of the box are respectively connected to the door frame 33, and the first seat body 341 and the second seat body 342 are respectively fixedly connected to the ends of the two guide rails 40.

[0120] In some embodiments, such as Figure 11 As shown, one of the first base 341 and the door frame 33 is provided with a first positioning post 3411, and the other of the first base 341 and the door frame 33 is provided with a first positioning hole 335. That is, when the first base 341 is provided with the first positioning post 3411, the first end cap 333 of the door frame 33 is provided with a first positioning hole 335 opposite to the first positioning post 3411. When the first base 341 is provided with the first positioning hole 335, the first end cap 333 of the door frame 33 is provided with a first positioning post 3411 opposite to the first positioning hole 335. The first positioning post 3411 passes through the first positioning hole 335, thereby playing a positioning role in the assembly of the first base 341 and the door frame 33, making it convenient to assemble the first base 341 to the designated position of the door frame 33.

[0121] Optionally, two first positioning posts 3411 are provided, and the two first positioning posts 3411 are arranged at intervals along the width direction of the first seat body 341. Correspondingly, two first positioning holes 335 are provided, and the two first positioning holes 335 are arranged at intervals along the width direction of the first seat body 341 and correspond to the first positioning holes 335 one by one, and a first positioning post 3411 is arranged in a first positioning hole 335, thereby facilitating the firm installation of the first seat body 341.

[0122] Further, in the width direction of the first seat body 341, the size of one of the first positioning holes 335 is greater than the size of the first positioning post 3411 matched therewith.

[0123] Due to inevitable machining errors, in the actual installation process, the first positioning post 3411 and the corresponding first positioning hole 335 will inevitably be misaligned, so that the first positioning post 3411 cannot be arranged in the first positioning hole 335 one by one. By making the size of one of the first positioning holes 335 in the width direction of the first seat body 341 greater than the size of the first positioning post 3411 matched therewith in the width direction of the first seat body 341, the positions of the two first positioning holes 335 relative to the corresponding first positioning posts 3411 can be easily adjusted to ensure that the first positioning post 3411 can be arranged in the first positioning hole 335 one by one, thereby ensuring that the first seat body 341 can be smoothly installed to the door frame 33.

[0124] Optionally, one of the first positioning holes 335 can be a strip hole, an oval hole, or a waist-shaped hole, and the first positioning post 3411 matched therewith is a circular post.

[0125] It should be explained that when the two ends of the fixed seat 34 in the height direction of the cabinet are connected with the door frame 33 respectively, the width direction of the first seat body 341 is the width direction of the cabinet; and when the two ends of the fixed seat 34 in the width direction of the cabinet are connected with the door frame 33 respectively, the width direction of the first seat body 341 is the height direction of the cabinet.

[0126] In some embodiments, as Figure 12As shown, one of the second seat body 342 and the door frame 33 is provided with a second positioning column 3421, and the other of the second seat body 342 and the door frame 33 is provided with a second positioning hole 336, that is, when the second seat body 342 is provided with the second positioning column 3421, the second end cover 334 of the door frame 33 is provided with the second positioning hole 336 opposite to the second positioning column 3421, and when the second seat body 342 is provided with the second positioning hole 336, the second end cover 334 of the door frame 33 is provided with the second positioning column 3421 opposite to the second positioning hole 336, and the second positioning column 3421 is arranged in the second positioning hole 336, thereby playing a positioning role in the assembly of the second seat body 342 and the door frame 33, and facilitating the assembly of the second seat body 342 to the specified position of the door frame 33.

[0127] Optionally, the second positioning column 3421 is provided with two second positioning columns 3421 arranged in the width direction of the second seat body 342. Correspondingly, the second positioning hole 336 is provided with two second positioning holes 336 arranged in the width direction of the second seat body 342 and corresponding to the second positioning hole 336, and a second positioning column 3421 is arranged in a second positioning hole 336, thereby facilitating the firmness of the installation of the second seat body 342.

[0128] Further, in the width direction of the second seat body 342, the size of one of the second positioning holes 336 is greater than the size of the second positioning column 3421 matched therewith.

[0129] Due to inevitable machining errors, in the actual installation process, the second positioning column 3421 and the corresponding second positioning hole 336 will inevitably be misaligned, so that the second positioning column 3421 cannot be arranged in the second positioning hole 336 one by one. By making the size of one of the second positioning holes 336 in the width direction of the second seat body 342 greater than the size of the second positioning column 3421 matched therewith in the width direction of the second seat body 342, the positions of the two second positioning holes 336 relative to the corresponding second positioning column 3421 can be conveniently coordinated to ensure that the second positioning column 3421 can be arranged in the second positioning hole 336 one by one, thereby ensuring that the second seat body 342 can be smoothly installed to the door frame 33.

[0130] Optionally, one of the second positioning holes 336 can be a strip-shaped hole, an oval hole or a waist-shaped hole, and the second positioning column 3421 matched therewith is a circular column.

[0131] It should be explained that when the two ends of the fixed seat 34 in the height direction of the box body are connected with the door frame 33 respectively, the width direction of the second seat body 342 is the width direction of the box body; and when the two ends of the fixed seat 34 in the width direction of the box body are connected with the door frame 33 respectively, the width direction of the second seat body 342 is the height direction of the box body.

[0132] In the present application, the first seat body 341 and the door frame 33 can be connected by clamping, screwing, bonding, etc.

[0133] Optionally, as shown in Figure 11 One of the first seat body 341 and the door frame 33 is provided with a first buckle 3412, and the other of the first seat body 341 and the door frame 33 is provided with a first clamping groove 337 arranged correspondingly with the first buckle 3412, for example, the first seat body 341 is provided with the first buckle 3412, and the door frame 33 is provided with the first clamping groove 337 arranged correspondingly with the first buckle 3412, when the first seat body 341 is connected to the door frame 33 in alignment, the first buckle 3412 is detachably clamped in the first clamping groove 337, so as to realize the clamping connection of the first seat body 341 and the door frame 33, and the installation mode is relatively simple and easy to operate.

[0134] In the present application, the second seat body 342 and the door frame 33 can be connected by clamping, screwing, bonding, etc.

[0135] Optionally, as shown in Figure 12 One of the second seat body 342 and the door frame 33 is provided with a second buckle 3422, and the other of the second seat body 342 and the door frame 33 is provided with a second clamping groove 338 arranged correspondingly with the second buckle 3422, for example, the second seat body 342 is provided with the second buckle 3422, and the door frame 33 is provided with the second clamping groove 338 arranged correspondingly with the second buckle 3422, when the second seat body 342 is connected to the door frame 33 in alignment, the second buckle 3422 is detachably clamped in the second clamping groove 338, so as to realize the clamping connection of the second seat body 342 and the door frame 33, and the installation mode is relatively simple and easy to operate.

[0136] In some embodiments, as shown in Figure 13 and Figure 14 The first seat body 341 is provided with a sliding groove 3413 and a notch 3414 in communication with the sliding groove 3413, the sliding groove 3413 extends along a preset direction, and the notch 3414 is located at an end surface of the first seat body 341 in the preset direction, the second seat body 342 is inserted into the sliding groove 3413 from the notch 3414, and the second seat body 342 is slidably arranged in the sliding groove 3413, so as to adjust the overall size of the fixing seat 34 in the preset direction.

[0137] In this way, when it is necessary to adjust the size of the fixing seat 34 in the preset direction, the second seat body 342 can be pulled out of the sliding groove 3413 or retracted into the sliding groove 3413, so as to change the overall size of the fixing seat 34 in the preset direction, and in this process, the sliding groove 3413 can guide the sliding of the second seat body 342, so as to improve the sliding stability of the second seat body 342 during the sliding process, and facilitate the adjustment of the overall size of the fixing seat 34 in the preset direction.

[0138] In addition, since the second seat 342 is embedded inside the first seat 341, compared with the side-by-side arrangement of the second seat 342 and the first seat 341, the overall width of the fixed seat 34 is smaller, reducing the occupancy of the fixed seat 34 on the receiving cavity, thereby allowing more foaming material to be accommodated in the receiving cavity and improving the heat insulation and thermal insulation performance of the drawer door 30.

[0139] Understandably, in other embodiments, a gear may be provided in one of the first seat 341 and the second seat 342, and a rack may be provided in the other of the first seat 341 and the second seat 342. By utilizing the meshing connection between the rack and the gear, the second seat 342 can also be moved relative to the first seat 341 in a preset direction to adjust the overall size of the fixed seat 34 in the preset direction.

[0140] In some embodiments, such as Figure 15 and Figure 16 As shown, the first seat 341 is provided with a first through groove 3415 that runs through the length of the box body. In this way, the foaming material can be filled into the first through groove 3415 of the first seat 341. On the one hand, it can enhance the installation stability of the fixed seat 34 in the receiving cavity and enhance the overall structural strength of the drawer door; on the other hand, it can increase the amount of foaming material and improve the heat insulation effect of the drawer door.

[0141] In some embodiments, the second seat 342 is provided with a second through groove 3423 extending along the length of the box body, so that the foaming material can be filled into the second through groove 3423 of the second seat 342. On the one hand, it can enhance the installation stability of the fixed seat 34 in the receiving cavity and enhance the overall structural strength of the drawer door; on the other hand, it can increase the amount of foaming material and improve the heat insulation and heat insulation effect of the drawer door.

[0142] In some embodiments, the first base 341 has a first groove wall 341a, a second groove wall 341b, a third groove wall 341c, and a fourth groove wall 341d. The second groove wall 341b and the first groove wall 341a are arranged opposite to each other and spaced apart along the length of the housing. The third groove wall 341c is connected between the first groove wall 341a and the second groove wall 341b. The fourth groove wall 341d is connected between the first groove wall 341a and the second groove wall 341b. The first groove wall 341a, the second groove wall 341b, the third groove wall 341c, and the fourth groove wall 341d together form a groove 3413 with the opening 3414 facing the second base 342. The second base 342 is inserted into the groove 3413 from the opening 3414. The second base 342 is slidably disposed in the groove 3413 to adjust the overall size of the fixed base 34 in a preset direction.

[0143] The second through slot 3423 has a through slot portion 3423a located in the sliding slot 3413, which is arranged at least partially corresponding to the first through slot 3415 in the length direction of the cabinet. In this way, the foaming material can enter the through slot portion 3423a located in the sliding slot 3413 through the first through slot 3415, so that the through slot portion 3423a located in the sliding slot 3413 can also be filled with foaming material, thereby further increasing the amount of foaming material and further improving the heat preservation and insulation effect of the drawer door.

[0144] It can be understood that when the entire second through slot 3423 is located in the sliding slot 3413, the through slot portion 3423a corresponds to the entire second through slot 3423.

[0145] In some embodiments, as shown in Figure 16 and Figure 17 , one of the groove wall surface of the sliding slot 3413 and the outer surface of the second seat body 342 is provided with a limiting recess 3416, and the other is provided with a limiting protrusion 3424, that is, when the groove wall surface of the sliding slot 3413 is provided with the limiting protrusion 3424, the outer surface of the second seat body 342 is provided with the limiting recess 3416; and when the groove wall surface of the sliding slot 3413 is provided with the limiting recess 3416, the outer surface of the second seat body 342 is provided with the limiting protrusion 3424. The limiting protrusion 3424 and the limiting recess 3416 are inserted, which can adopt clearance fit or transition fit between the second seat body 342 and the sliding slot 3413, so as to reduce the friction between the second seat body 342 and the sliding slot 3413, while avoiding the second seat body 342 from being separated from the sliding slot 3413.

[0146] As an embodiment, the limiting recess 3416 is provided with a plurality of limiting recesses 3416 arranged at intervals in a predetermined direction, and the limiting protrusion 3424 is provided with one limiting protrusion 3424 which can be inserted with any limiting recess 3416 to change the position of the second seat body 342 in the sliding slot 3413, thereby changing the overall size of the fixing seat 34 in the predetermined direction.

[0147] Specifically, when the second seat body 342 is pulled out of the sliding groove 3413 or pushed into the sliding groove 3413, the limiting protrusion 3424 inserted in the limiting groove 3416 is pulled out of the limiting groove 3416, so that the second seat body 342 can slide in the sliding groove 3413 to adjust the overall size of the fixing seat 34 in the preset direction. When the size of the fixing seat 34 in the preset direction is adjusted to the target size, the limiting protrusion 3424 is not inserted in the limiting groove 3416 as before, but is inserted in another limiting groove 3416, so as to fix the second seat body 342 in the sliding groove 3413, avoiding the second seat body 342 from being separated from the sliding groove 3413.

[0148] As another embodiment, the limiting protrusion 3424 is provided in plurality, the plurality of limiting protrusions 3424 are arranged along the preset direction at intervals, the limiting groove 3416 is provided in one, and the limiting groove 3416 can be inserted with any one of the limiting protrusions 3424 to change the position of the second seat body 342 in the sliding groove 3413, so as to change the overall size of the fixing seat 34 in the preset direction.

[0149] Specifically, when the second seat body 342 is pulled out of the sliding groove 3413 or pushed into the sliding groove 3413, the limiting protrusion 3424 inserted in the limiting groove 3416 is pulled out of the limiting groove 3416, so that the second seat body 342 can slide in the sliding groove to adjust the overall size of the fixing seat 34 in the preset direction. When the size of the fixing seat 34 in the preset direction is adjusted to the target size, the limiting groove 3416 is not inserted with the limiting protrusion 3424 as before, but is inserted with another limiting protrusion 3424, so as to fix the second seat body 342 in the sliding groove 3413, avoiding the second seat body 342 from being separated from the sliding groove 3413.

[0150] As another embodiment, the limiting protrusion 3424 is provided in plurality, the plurality of limiting protrusions 3424 are arranged along the preset direction at intervals, the limiting groove 3416 is provided in one, and the limiting groove 3416 can be inserted with any one of the limiting protrusions 3424 to change the position of the second seat body 342 in the sliding groove 3413, so as to change the overall size of the fixing seat 34 in the preset direction.

[0151] Specifically, when the second seat 342 is pulled out of the slide groove 3413 or pushed into the slide groove 3413, the limiting protrusion 3424 inserted in the limiting groove 3416 will be pulled out of the limiting groove 3416, allowing the second seat 342 to slide in the slide groove 3413 to adjust the overall size of the fixing seat 34 in the preset direction. When the size of the fixing seat 34 in the preset direction is adjusted to the target size, the limiting groove 3416 is not inserted with the previously inserted limiting protrusion 3424, but is inserted with other limiting protrusions 3424 to fix the second seat 342 in the slide groove 3413 and prevent the second seat 342 from falling out of the slide groove 3413.

[0152] Optionally, the limiting groove 3416 can be an arc-shaped protrusion, and the limiting protrusion 3424 can be an arc-shaped groove. This makes it convenient to pull the limiting groove 3416 out of the limiting protrusion 3424 or insert the limiting groove 3416 into the limiting protrusion 3424 when the second seat 342 is pulled out of the slide groove 3413 or pushed into the slide groove 3413.

[0153] like Figures 18 to 20 As shown, the second groove wall 341b is provided with four limiting grooves 3416, which are sequentially named first limiting groove 3416a, second limiting groove 3416b, third limiting groove 3416c, and fourth limiting groove 3416d. In a predetermined direction, the first limiting groove 3416a is furthest from the groove opening. The second seat 342 is provided with four limiting protrusions 3424, which are sequentially named first limiting protrusion 3424a, second limiting protrusion 3424b, third limiting protrusion 3424c, and fourth limiting protrusion 3424d. In a predetermined direction, the first limiting protrusion 3424a is closest to the first limiting groove 3416a.

[0154] Figure 18 The fixed base 34 is shown to be at its shortest length in the preset direction. At this time, it can be considered that the second base 342 is almost inserted into the slide groove of the first base 341. It is used for the drawer door 30 with the smallest height or width. At this time, the four limiting protrusions on the second base 342 and the four limiting grooves in the slide groove match one by one. The stability of the second base 342 in the slide groove is the highest and the volume is the smallest. The fixed base 34 in this state is also convenient for transportation.

[0155] Figure 19 The fixed seat 34 is shown to be the longest in the preset direction. At this time, it can be regarded that the second seat 342 is almost entirely located in the groove of the first seat 341. It is used for the drawer door 30 with the smallest height or width. At this time, only the first limiting protrusion 3424a and the fourth limiting groove 3416d are inserted.

[0156] Figure 20 It is shown that the size of the fixing seat 34 in the preset direction is between the shortest size and the longest size, at this time the first limiting protrusion 3424a is inserted with the second limiting groove 3416b, the second limiting protrusion 3424b is inserted with the third limiting groove 3416c, and the third limiting protrusion 3424c is inserted with the fourth limiting groove 3416d.

[0157] It can be understood that the number of limiting protrusions 3424 and limiting grooves 3416, and the distance between adjacent two limiting protrusions 3424 and the distance between adjacent two limiting grooves 3416, can be designed according to several common heights or widths of the drawer door 30 on the market, so that the size of the fixing seat 34 in the preset direction can be suitable for drawer doors 30 of different heights or widths, so as to achieve the purpose of generalization and reduce the cost of repeated mold opening.

[0158] In some embodiments, as shown in Figures 21 to 23 The surface of the first slot wall 341a towards the second slot wall 341b is provided with a guide protrusion 3417 extending in the preset direction, and the surface of the second seat body 342 towards the first slot wall 341a is provided with a guide groove 3425 extending in the preset direction, and the guide protrusion 3417 is slidably arranged in the guide groove 3425.

[0159] Among them, the first through groove 3415 includes a first sub-through groove 3415a arranged on the first slot wall 341a and a second sub-through groove 3415b arranged on the guide protrusion 3417, the first sub-through groove 3415a and the second sub-through groove 3415b are communicated, the second through groove 3423 penetrates the bottom surface of the guide groove 3425, and the through groove part 3423a of the second through groove 3423 is arranged corresponding to the second sub-through groove 3415b in the length direction of the box body, so that the foaming material can enter the through groove part 3423a located in the sliding groove 3413 through the first sub-through groove 3415a and the second sub-through groove 3415b, so that the through groove part 3423a located in the sliding groove 3413 can also be filled with foaming material, thereby further increasing the amount of foaming material and further improving the heat preservation and heat insulation effect of the drawer door.

[0160] The guiding protrusion 3417 and the guiding groove 3425 can guide the sliding of the second seat body 342 relative to the first seat body 341, improve the sliding stability of the second seat body 342 during the sliding, and facilitate adjustment of the overall size of the fixing seat 34 in the preset direction. In addition, the first through groove 3415 weakens the structural strength of the first groove wall 341a, and the guiding protrusion 3417 can reinforce the first groove wall 341a to compensate for the weakening of the structural strength of the first groove wall 341a caused by the first through groove 3415.

[0161] In some embodiments, as shown in Figure 21 and Figure 22 the third groove wall 341c is provided with a plurality of first protrusions 3418 arranged at intervals in the preset direction, and the plurality of first protrusions 3418 respectively abut against the second seat body 342. In this way, the plurality of first protrusions 3418 can not only enhance the structural strength of the third groove wall 341c and the strength of the first seat body 341, but also reduce the contact area between the third groove wall 341c and the second seat body 342, reduce the friction between the third groove wall 341c and the second seat body 342, and facilitate the sliding of the second seat body 342 relative to the sliding groove 3413, thereby facilitating adjustment of the overall size of the fixing seat 34 in the preset direction.

[0162] In some embodiments, the fourth groove wall 341d is provided with a plurality of second protrusions 3419 arranged at intervals in the preset direction, and the plurality of second protrusions 3419 respectively abut against the second seat body 342. In this way, the plurality of second protrusions 3419 can not only enhance the structural strength of the fourth groove wall 341d and the strength of the first seat body 341, but also reduce the contact area between the fourth groove wall 341d and the second seat body 342, reduce the friction between the fourth groove wall 341d and the second seat body 342, and facilitate the sliding of the second seat body 342 relative to the sliding groove 3413, thereby facilitating adjustment of the overall size of the fixing seat 34 in the preset direction.

[0163] In some embodiments, the first through groove 3415 includes a plurality of first sub-through grooves 3415a arranged on the first groove wall 341a, and the plurality of first sub-through grooves 3415a are arranged in a matrix along the length direction of the first seat body 341 and the width direction of the first seat body 341.
