Abstract
Description
Technical Field
[0001] The present application relates to the field of refrigeration equipment, and particularly to a slide rail device, a box body assembly and a refrigerator. Background Art
[0002] As a container that can keep food or other items at a constant low temperature, the refrigerator has become one of the essential household appliances in modern families. The refrigerator usually includes a refrigerating chamber and a freezing chamber that are separated up and down to store items that need to be preserved at different temperatures. In order to facilitate the placement of some items, the refrigerating chamber and the freezing chamber are usually provided with a box body that can be pulled out.
[0003] In the related art, for the box body structure that is pulled out obliquely upward, due to the lack of a corresponding limiting mechanism, the box body is prone to slide relative to the box liner under the action of gravity, resulting in the box body being unable to stay at the target position and reducing the user experience. Summary of the Invention
[0004] The present application provides a slide rail device. The guide rail seat and the guide rail bracket of the slide rail device will not slide relative to each other under the action of gravity, and the box body can be stopped at the required position, providing a better user experience.
[0005] The present application also provides a box body assembly
[0006] The present application also provides a refrigerator.
[0007] The slide rail device of the embodiment of the present application includes: a guide rail seat, the guide rail seat extends along a first direction, the guide rail seat is provided with a first wall surface along a second direction, and the first direction is orthogonal to the second direction; a guide rail bracket, the guide rail bracket is slidably connected to the guide rail seat along the first direction; a limiting component, the limiting component includes a limiting member and a first elastic member, the limiting member can be switched between a released state and a locked state, in the locked state, the limiting member is spaced apart from the first wall surface, in the released state, the first elastic member presses the limiting member towards the direction of the first wall surface, the limiting member is movable relative to the guide rail bracket along the second direction and abuts against the first wall surface.
[0008] The slide rail device according to an embodiment of the present application. Since the limiting member is switchable between a released state and a locked state, in the locked state, the limiting member is spaced apart from the first wall surface, thereby enabling the free sliding between the guide rail bracket and the guide rail seat to avoid the problem of jamming when the guide rail bracket slides relative to the guide rail seat. Since the first elastic member presses the limiting member in the direction towards the first wall surface, the limiting member can move relative to the guide rail bracket in the second direction in the released state, and the limiting member abuts against the first wall surface. Thus, under the action of the elastic force of the first elastic member, the relative movement between the guide rail bracket and the guide rail seat can be restricted to avoid the problem that the guide rail bracket moves relative to the guide rail seat under the action of gravity. Thereby, the box body can be stopped at the desired position, improving the user experience.
[0009] In some embodiments, a plurality of positioning grooves are provided on the first wall surface, and the plurality of positioning grooves are arranged at intervals along the first direction. The guide rail seat has a first end and a second end arranged oppositely along the first direction. When the guide rail bracket moves in the direction from the first end to the second end, the limiting member is in the released state so that the limiting member extends into different positioning grooves.
[0010] In some embodiments, the limiting member has a first stop surface arranged towards the second end. In the direction from the first end to the second end, the first stop surface extends obliquely in a direction gradually away from the first wall surface. When the guide rail bracket moves in the direction from the first end to the second end, the first stop surface can slide relative to the outer edge of the positioning groove so that the limiting member disengages from the positioning groove.
[0011] In some embodiments, the limiting member has a second stop surface arranged towards the first end, and the second stop surface can abut against the inner wall surface of the positioning groove to limit the limiting member from disengaging from the positioning groove in the direction from the second end to the first end.
[0012] In some embodiments, the guide rail seat has a first end and a second end arranged oppositely along the first direction. The limiting component further includes a main housing and a locking component. The main housing is provided on the guide rail seat, and both the limiting member and the locking component are connected to the main housing. When the main housing moves to the second end, the locking component can restrict the movement of the limiting member to switch the limiting member to the locked state. When the main housing moves to the first end, the locking component and the limiting member can move relative to each other to switch the limiting member to the released state.
[0013] In some embodiments, the first wall surface is provided with a convex portion, and the convex portion is arranged near the second end. When the main housing moves to the second end, the limiting member can move in a direction away from the first wall surface under the guiding action of the convex portion, so as to switch the limiting member to the locked state.
[0014] In some embodiments, the locking member includes a guiding frame and a second elastic member. The guiding frame is slidably mounted on the main housing along the first direction, the second elastic member presses the guiding frame along the direction towards the first end, a first mating portion is provided on one side of the guiding frame facing the second end, and a second mating portion is provided on the limiting member. In the locked state, the first mating portion and the second mating portion are in alignment and mating. In the released state, the first mating portion and the second mating portion are spaced apart along the second direction.
[0015] In some embodiments, one of the first mating portion and the second mating portion is a stop rod, and the other is a groove. In the locked state, the stop rod is engaged with the groove. In the released state, the stop rod and the groove are spaced apart along the second direction.
[0016] In some embodiments, first sliding grooves are provided on both sides of the main housing along the third direction. The first direction, the second direction, and the third direction are orthogonal to each other pairwise. The guiding frame includes two first guiding rods. The two first guiding rods are arranged on both sides of the main housing along the third direction and are slidably engaged with the first sliding grooves. The stop rods are respectively connected to the two first guiding rods, and the groove is provided on the limiting member.
[0017] In some embodiments, a third mating portion is provided on one side of the guiding frame facing the first end, and a stop baffle is provided at the first end of the guide rail seat. When the third mating portion presses the stop baffle along the direction from the second end to the first end, the first mating portion and the second mating portion are spaced apart along the second direction to release the limiting member.
[0018] In some embodiments, a second sliding groove is provided in the main housing, and the limiting member has a second guiding rod. The second guiding rod slidably penetrates through the second sliding groove along the second direction; and / or, one end of the first elastic member abuts against the limiting member, and the other end of the first elastic member abuts against the main housing.
[0019] In some embodiments, a first clamping portion is provided on one of the main housing and the guide rail bracket, and a first clamping groove is provided on the other. The first clamping portion is clamped with the first clamping groove; and / or, the limiting assembly further includes a first fastener, and the first fastener penetrates through the main housing and the guide rail bracket.
[0020] In some embodiments, the slide rail device further includes rollers rotatably mounted on the guide rail bracket, and the outer wall surface of the rollers abuts against the guide rail seat.
[0021] A cabinet assembly according to another embodiment of the present application includes: an inner cabinet, a cabinet, and a slide rail device. The slide rail device is the slide rail device according to any one of the embodiments of the present application. The cabinet is slidably mounted in the inner cabinet. The guide rail seat is connected to the inner cabinet, and the guide rail bracket is connected to the cabinet. Both the guide rail seat and the guide rail bracket extend obliquely upward in the direction from the front side to the rear side of the cabinet.
[0022] In the cabinet assembly according to the embodiment of the present application, since the limiting member is switchable between a released state and a locked state, in the locked state, the limiting member is spaced apart from the first wall surface, thereby enabling the free sliding between the guide rail bracket and the guide rail seat to avoid the problem of jamming when the guide rail bracket and the guide rail seat slide. Since the first elastic member presses the limiting member toward the first wall surface, the limiting member can move relative to the guide rail bracket in the second direction in the released state, and the limiting member abuts against the first wall surface. Thus, under the action of the elastic force of the first elastic member, the relative movement between the guide rail bracket and the guide rail seat can be restricted to avoid the problem that the guide rail bracket moves relative to the guide rail seat under the action of gravity. Thereby, the cabinet can be stopped at the desired position, improving the user experience.
[0023] A refrigerator according to another embodiment of the present application includes the cabinet assembly according to the embodiment of the present application.
[0024] In the refrigerator according to the embodiment of the present application, since the limiting member is switchable between a released state and a locked state, in the locked state, the limiting member is spaced apart from the first wall surface, thereby enabling the free sliding between the guide rail bracket and the guide rail seat to avoid the problem of jamming when the guide rail bracket and the guide rail seat slide. Since the first elastic member presses the limiting member toward the first wall surface, the limiting member can move relative to the guide rail bracket in the second direction in the released state, and the limiting member abuts against the first wall surface. Thus, under the action of the elastic force of the first elastic member, the relative movement between the guide rail bracket and the guide rail seat can be restricted to avoid the problem that the guide rail bracket moves relative to the guide rail seat under the action of gravity. Thereby, the cabinet can be stopped at the desired position, improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.
[0050] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed.
[0051] For ease of description, spatially relative relationship terms may be used in the text to describe the relative positional relationship or movement of one element or feature shown in the figure relative to another element or feature. These relative relationship terms are, for example, "inside", "outside", "inner side", "outer side", "below", "beneath", "above", "over", "front", "rear", etc. Such spatially relative relationship terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or attitude change or movement state change, then these directional indications will change accordingly. For example, an element described as "below" or "beneath" other elements or features will then be oriented as "above" or "over" other elements or features. Thus, the example term "below" can include both the upper and lower orientations. The device can be oriented otherwise (rotated 90 degrees or in other directions) and the spatially relative relationship descriptors used in the text are interpreted accordingly.
[0052] The following refers to the Figures 1 to 15 slide rail device, box assembly, and refrigerator of the embodiments of the present application are described.
[0053] As Figures 1 to 4 shown, the slide rail device of the embodiments of the present application includes: a guide rail base 1, a guide rail bracket 2, and a limit assembly 3. The guide rail base 1 extends along a first direction (such as the Figure 2 front-back direction), the guide rail base 1 is provided with a first wall surface 13 along a second direction (such as the Figure 2 left-right direction), the first direction is orthogonal to the second direction, and the guide rail bracket 2 is slidably connected to the guide rail base 1 along the first direction.
[0054] The limit assembly 3 includes a limit member 31 and a first elastic member 32. The limit member 31 is switchable between a released state and a locked state. In the locked state, the limit member 31 is spaced apart from the first wall surface 13. In the released state, the first elastic member 32 presses the limit member 31 in the direction towards the first wall surface 13. The limit member 31 is movable relative to the guide rail bracket 2 along the second direction and abuts against the first wall surface 13.
[0055] According to the slide rail device of an embodiment of the present application, since the limiting member 31 is switchable between a released state and a locked state, in the locked state, the limiting member 31 is spaced apart from the first wall surface 13, whereby the guide rail bracket 2 can slide freely between the guide rail seat 1 to avoid the problem of jamming when the guide rail bracket 2 slides relative to the guide rail seat 1. Since the first elastic member 32 presses the limiting member 31 towards the first wall surface 13, the limiting member 31 can move relative to the guide rail bracket 2 in the second direction in the released state, and the limiting member 31 abuts against the first wall surface 13. Thus, under the action of the elastic force of the first elastic member 32, the relative movement between the guide rail bracket 2 and the guide rail seat 1 can be restricted to avoid the problem that the guide rail bracket 2 moves relative to the guide rail seat 1 under the action of gravity. Thereby, the box body 5 can be stopped at the required position, improving the user experience.
[0056] As Figure 2 shown, the guide rail bracket 2 is used to be mounted on the box body 5. When the user pulls and draws the box body 5, the guide rail bracket 2 can slide relative to the guide rail seat 1 in the first direction.
[0057] As Figure 2 and Figure 3 shown, the slide rail device is arranged obliquely upward in the front-to-rear direction. When the box body 5 is pulled obliquely upward in the front-to-rear direction, due to the certain weight of the box body 5, under the action of gravity, the box body 5 will give a downward component force to the guide rail bracket 2. Since the limiting member 31 can move relative to the guide rail bracket 2 in the second direction in the released state, and the limiting member 31 abuts against the first wall surface 13, therefore, under the cooperation of the limiting member 31 and the first wall surface 13, the guide rail bracket 2 will not slide downward due to the gravity of the box body 5. Thereby, the box body 5 can be stopped at the position required by the user to improve the user experience.
[0058] Optionally, as Figure 7 and Figure 12 shown, a plurality of positioning grooves 131 are provided on the first wall surface 13, and the plurality of positioning grooves 131 are arranged at intervals in the first direction. The guide rail seat 1 has a first end 11 and a second end 12 arranged oppositely in the first direction. When the guide rail bracket 2 moves in the direction from the first end 11 to the second end 12, the limiting member 31 is in the released state so that the limiting member 31 can extend into different positioning grooves 131.
[0059] As Figure 2As shown, the first end 11 is the rear end of the guide rail base 1, and the second end 12 is the front end of the guide rail base 1. That is to say, the front-back direction of the guide rail base 1 is consistent with the front-back direction during the actual use of the refrigerator. When the guide rail bracket 2 moves in the direction from the rear to the front, the limiting member 31 is in a released state so that the limiting member 31 can extend into different positioning grooves 131, thereby fixing the sliding position of the guide rail bracket 2 and further preventing the problem that the guide rail bracket 2 slides downward under the gravity of the box body 5, which is beneficial to improving the stability of the guide rail bracket 2 when it stays.
[0060] It should be noted that the number of the positioning grooves 131 can be two, three or more than three, and the present application does not limit this.
[0061] Optionally, as Figure 10 and Figure 14 shown, the limiting member 31 has a first stop surface 311, the first stop surface 311 is arranged facing the second end 12, and in the direction from the first end 11 to the second end 12, the first stop surface 311 extends obliquely in the direction gradually away from the first wall surface 13. When the guide rail bracket 2 moves in the direction from the first end 11 to the second end 12, the first stop surface 311 can slide relative to the outer edge of the positioning groove 131 so that the limiting member 31 can be disengaged from the positioning groove 131.
[0062] It can be understood that the first stop surface 311 is an inclined surface. When the guide rail bracket 2 moves in the direction from the first end 11 to the second end 12, since the limiting member 31 is movable relative to the guide rail bracket 2 in the second direction, under the guiding action of the first stop surface 311, the limiting member 31 can gradually retract and disengage from the positioning groove 131. Thus, when the user pulls the guide rail bracket 2 in the direction from the first end 11 to the second end 12 (such as Figure 2 the direction from the rear to the front in Figure 2 ), the positioning groove 131 will neither limit the movement of the guide rail bracket 2 in the direction from the first end 11 to the second end 12 nor can temporarily lock the guide rail bracket 2, greatly reducing the problem that the guide rail bracket 2 retreats in the direction from the second end 12 to the first end 11 (such as
[0063] the direction from the front to the rear in Figure 10 and Figure 14 ), so that the box body 5 can stay stably at different positions. Figure 2When there is a tendency for the guide rail bracket 2 to move in the direction from the front to the back, the second stop surface 312 can be in contact with the inner wall surface of the positioning groove 131, thereby preventing the guide rail bracket 2 from retracting in the direction from the second end 12 to the first end 11, and thus improving the stability of the box body 5 when it stays at the target position.
[0064] For example, the plane where the second stop surface 312 is located is orthogonal to the first direction to improve the stop effect of the second stop surface 312.
[0065] Optionally, as Figure 2 and Figure 6 shown, the guide rail base 1 has a first end 11 and a second end 12 arranged oppositely in the first direction. The limiting component 3 further includes a main housing 33 and a locking component 34. The main housing 33 is arranged on the guide rail base 1. Both the limiting member 31 and the locking component 34 are connected to the main housing 33. When the main housing 33 moves to the second end 12, the locking component 34 can limit the movement of the limiting member 31 to switch the limiting member 31 to the locked state. When the main housing 33 moves to the first end 11, the locking component 34 and the limiting member 31 can move relatively to switch the limiting member 31 to the released state.
[0066] It can be understood that, as Figure 14 shown, when the guide rail bracket 2 drives the main housing 33 to move in the direction towards the second end 12 until the main housing 33 moves to the extreme position of the second end 12, the locking component 34 can lock the limiting member 31. At this time, the limiting member 31 is in the locked state, that is, the limiting member 31 cannot move in the second direction and is spaced apart from the first wall surface 13. Thus, when the guide rail bracket 2 moves in the direction from the second end 12 to the first end 11, the limiting member 31 will not collide with the guide rail base 1, thereby ensuring that the guide rail bracket 2 can be reset smoothly, that is, the box body 5 retracts into the inner box.
[0067] When the guide rail bracket 2 drives the main housing 33 to move in the direction towards the first end 11 until the main housing 33 moves to the extreme position of the first end 11, the locking component 34 can unlock the limiting member 31. At this time, the limiting member 31 is in the released state, thus preparing for the next extraction of the guide rail bracket 2. Therefore, by setting the limiting component 3 as the above structure in the embodiment of the present application, the linkage effect between the limiting member 31 and the locking component 34 can be improved, and the action process is smooth and convenient for users to use.
[0068] Optionally, as Figure 12 and Figure 15As shown, the first wall 13 is provided with a protrusion 132, which is arranged near the second end 12. When the main housing 33 moves to the second end 12, the limiter 31 can move in a direction away from the first wall 13 under the guidance of the protrusion 132, so that the limiter 31 is switched to a locked state. It can be understood that when the main housing 33 moves to the second end 12 along with the guide rail bracket 2, the limiter 31 can move in a direction away from the first wall 13 under the guidance of the protrusion 132, so that the first wall 13 is separated from the limiter 31. At this time, the locking component 34 locks the limiter 31, so that the limiter 31 is switched to a locked state. By providing the protrusion 132, the slide rail device of the embodiment of the present application can automatically separate the limiter 31 from the first wall 13 when the guide rail bracket 2 is withdrawn forward to the limit position, without the need for a drive source such as a motor, which is conducive to reducing the production cost of the slide rail device, and has a simple structural design and reliable operation.
[0069] For example, Figure 12 As shown, the protrusion 132 has a guiding inclined surface 1321 , and the first stop surface 311 and the guiding inclined surface 1321 can be slidably matched in a surface contact manner to avoid jamming when the limiting member 31 contacts the protrusion 132 .
[0070] Alternatively, as Figures 7 to 10 As shown, the locking component 34 includes a guide frame 341 and a second elastic member 342. The guide frame 341 is slidably installed on the main shell 33 along the first direction. The second elastic member 342 presses the guide frame 341 in the direction toward the first end 11. The guide frame 341 is provided with a first matching portion 3411 on the side facing the second end 12, and a second matching portion 313 is provided on the limiting member 31. In the locked state, the first matching portion 3411 and the second matching portion 313 are aligned and matched. In the released state, the first matching portion 3411 and the second matching portion 313 are spaced apart along the second direction.
[0071] like Figure 14 As shown, when the guide rail bracket 2 drives the main shell 33 to move toward the second end 12 until the main shell 33 moves to the extreme position of the second end 12, the limit member 31 can move in the direction away from the first wall 13 under the guidance of the protrusion 132, thereby aligning the first matching portion 3411 and the second matching portion 313 to put the limit member 31 in a locked state.
[0072] like Figure 13 As shown, when the guide rail bracket 2 drives the main shell 33 to move toward the first end 11 until the main shell 33 moves to the extreme position of the first end 11, the first matching portion 3411 and the second matching portion 313 can be spaced apart along the second direction to unlock the limit member 31, thereby preparing for the next extraction of the guide rail bracket 2.
[0073] By arranging the locking member 34 in the above structure, the slide rail device according to the embodiment of the present application can automatically switch the state of the limiting member 31 when the guide rail bracket 2 is pulled to the limit position, improving the linkage effect between the limiting member 31 and the locking member 34. The structural design is reasonable and the use effect is good.
[0074] Optionally, as Figure 7 and Figure 10 shown, one of the first engaging portion 3411 and the second engaging portion 313 is the stop rod 34111, and the other is the groove 3131. In the locked state, the stop rod 34111 is engaged with the groove 3131, and in the released state, the stop rod 34111 is spaced apart from the groove 3131 in the second direction. It should be noted that when the limiting member 31 is in the released state, whether the limiting member 31 abuts against the first wall surface 13 or the limiting member 31 extends into the positioning groove 131, the stop rod 34111 and the groove 3131 are both spaced apart in the second direction.
[0075] Exemplarily, the first engaging portion 3411 is the stop rod 34111, and the second engaging portion 313 is the groove 3131. After the stop rod 34111 is engaged with the groove 3131, the position of the limiting member 31 can be locked to restrict the movement of the limiting member 31 in the second direction, so that the guide rail bracket 2 can be smoothly retracted to the first end 11. By arranging the first engaging portion 3411 and the second engaging portion 313 in the above structure, the slide rail device according to the embodiment of the present application is convenient for the processing and manufacturing of the first engaging portion 3411 and the second engaging portion 313, and the action is reliable.
[0076] For example, as Figure 7 and Figure 10 shown, the groove 3131 is a semi-cylindrical groove, and the cross-sectional profile of the stop rod 34111 is circular, thereby improving the smoothness when the stop rod 34111 is disengaged from or engaged with the groove 3131.
[0077] Optionally, as Figure 7 and Figure 11 shown, the main housing 33 is provided with first slideways 331 on both sides in the third direction. The first direction, the second direction, and the third direction are orthogonal to each other. The guide frame 341 includes two first guide rods 3412. The two first guide rods 3412 are arranged on both sides of the main housing 33 in the third direction and are slidably engaged with the first slideways 331. The stop rods 34111 are respectively connected to the two first guide rods 3412, and the groove 3131 is provided on the limiting member 31. It can be understood that the first guide rods 3412 can slide in the first slideways 331, and the first slideways 331 can provide position constraints for the sliding of the guide frame 341 to improve the smoothness of the sliding of the guide frame 341.
[0078] One end of the second elastic member 342 in the first direction abuts against the main housing 33, and the other end of the second elastic member 342 in the first direction abuts against the guide frame 341. The second elastic member 342 presses the guide frame 341 in the direction towards the first end 11, so that there is an elastic contact force between the stop rod 34111 and the limiting member 31. It should be noted that the elastic force of the second elastic member 342 is greater than the elastic force of the first elastic member 32. When the stop rod 34111 is stuck into the groove 3131, the elastic force of the first elastic member 32 will not drive the groove 3131 to escape from the stop rod 34111.
[0079] Optionally, as Figure 8 and Figure 10 shown, a third mating portion 3413 is provided on one side of the guide frame 341 facing the first end 11, and a stop plate 14 is provided at the first end 11 of the guide rail seat 1. When the third mating portion 3413 presses the stop plate 14 in the direction from the second end 12 to the first end 11, the first mating portion 3411 and the second mating portion 313 are spaced apart in the second direction to release the limiting member 31.
[0080] When the guide rail bracket 2 drives the main housing 33 to move in the direction towards the first end 11 until the main housing 33 moves to the limit position at the first end 11, the third mating portion 3413 can press the stop plate 14 in the direction from the second end 12 to the first end 11. Since the guide frame 341 can slide relative to the first direction, the stop rod 34111 is disengaged from the groove 3131. Under the action of the first elastic member 32, the limiting member 31 can move in the direction towards the first wall surface 13, so that the first mating portion 3411 (stop rod 34111) and the second mating portion 313 (groove 3131) can be spaced apart in the second direction to prepare for the next extraction of the guide rail bracket 2. By adopting the above structural arrangement, the slide rail device of the embodiment of the present application can automatically switch the state of the limiting member 31 when the guide rail bracket 2 is pulled to the limit position, improving the linkage effect between the various components of the slide rail device, with reasonable structural design and good use effect.
[0081] Optionally, as Figure 10 shown, a second slideway 332 is provided in the main housing 33, and the limiting member 31 has a second guide rod 314. The second guide rod 314 slidably penetrates through the second slideway 332 in the second direction. Thus, the first slideway 331 can provide guidance for the movement of the second guide rod 314 to make the movement of the limiting member 31 more stable.
[0082] As Figure 10 and Figure 11 shown, one end of the first elastic member 32 abuts against the limiting member 31, and the other end of the first elastic member 32 abuts against the main housing 33, which can improve the connection stability of the first elastic member 32. Exemplarily, the first elastic member 32 is a cylindrical spring.
[0083] Optionally, as Figure 7 and Figure 8 shown, a first clamping portion 333 is provided on one of the main housing 33 and the guide rail bracket 2, and a first clamping groove 21 is provided on the other. The first clamping portion 333 is clamped with the first clamping groove 21. Thereby, the convenience of connecting the main housing 33 and the guide rail bracket 2 can be improved. For example, the first clamping portion 333 is two hooks, and the two hooks are arranged on both sides of the main housing 33 along the third direction (up and down direction), and the hooks are clamped with the first clamping groove 21.
[0084] As Figure 7 and Figure 8 shown, the limiting component 3 further includes a first fastener 35, and the first fastener 35 passes through the main housing 33 and the guide rail bracket 2. Thereby, the reliability of connecting the main housing 33 and the guide rail bracket 2 can be improved. For example, the first fastener 35 is a bolt.
[0085] Optionally, as Figure 4 and Figure 7 shown, the slide rail device further includes a roller 4, and the roller 4 is rotatably installed on the guide rail bracket 2, and the outer wall surface of the roller 4 abuts against the guide rail seat 1. Thereby, the resistance when the guide rail bracket 2 and the guide rail seat 1 slide relative to each other can be reduced, and the noise generated by sliding friction during the operation of the slide rail device can be reduced.
[0086] As Figure 1 and Figure 2 shown, the box body assembly of another embodiment of the present application includes: a box liner, a box body 5 and a slide rail device. The slide rail device is the slide rail device of the present application. The box body 5 is slidably installed in the box liner. The guide rail seat 1 is connected to the box liner, and the guide rail bracket 2 is connected to the box body 5. Both the guide rail seat 1 and the guide rail bracket 2 extend obliquely upward in the direction from the front side of the box body 5 to the rear side of the box body 5.
[0087] According to the box body assembly of the embodiment of the present application, since the limiting member 31 can be switched between a released state and a locked state, in the locked state, the limiting member 31 is spaced apart from the first wall surface 13. Thereby, the guide rail bracket 2 and the guide rail seat 1 can slide freely, so as to avoid the problem of jamming when the guide rail bracket 2 and the guide rail seat 1 slide. Since the first elastic member 32 presses the limiting member 31 in the direction towards the first wall surface 13, the limiting member 31 can move relative to the guide rail bracket 2 in the second direction in the released state, and the limiting member 31 abuts against the first wall surface 13. Thereby, under the elastic force of the first elastic member 32, the relative movement of the guide rail bracket 2 and the guide rail seat 1 can be restricted, so as to avoid the problem that the guide rail bracket 2 moves relative to the guide rail seat 1 under the action of gravity. Thereby, the box body 5 can be stopped at the required position, and the user experience can be improved.
[0088] Optionally, as Figure 1 and Figure 2As shown, the inclination angles of the guide rail base 1 and the guide rail bracket 2 with respect to the horizontal plane are between 30° and 40°, which facilitates the daily use of the user and does not interfere with the components around the box body 5. Exemplarily, the inclination angles of the guide rail base 1 and the guide rail bracket 2 with respect to the horizontal plane are 35°.
[0089] As Figure 5 and Figure 6 shown, the bottom surface of the box body 5 is provided with a mounting block 51, and the guide rail bracket 2 is provided with a mounting groove 22. The mounting block 51 is inserted into the mounting groove 22 in the direction from top to bottom, so as to facilitate the assembly of the box body 5 and the guide rail bracket 2.
[0090] As Figure 1 and Figure 2 shown, the refrigerator of another embodiment of the present application includes the box body assembly of the embodiment of the present application.
[0091] In the refrigerator according to the embodiment of the present application, since the limiting member 31 can be switched between the released state and the locked state, in the locked state, the limiting member 31 is spaced apart from the first wall surface 13, so that the guide rail bracket 2 can slide freely relative to the guide rail base 1 to avoid the problem of jamming when the guide rail bracket 2 slides relative to the guide rail base 1. Since the first elastic member 32 presses the limiting member 31 in the direction towards the first wall surface 13, the limiting member 31 can move relative to the guide rail bracket 2 in the second direction in the released state, and the limiting member 31 abuts against the first wall surface 13. Thus, under the action of the elastic force of the first elastic member 32, the relative movement of the guide rail bracket 2 and the guide rail base 1 can be restricted to avoid the problem that the guide rail bracket 2 moves relative to the guide rail base 1 under the action of gravity. Thus, the box body 5 can be stopped at the required position, improving the user experience.
[0092] Exemplarily, as Figure 1 and Figure 2 shown, the box body assembly is arranged near the lower side of the refrigerator and has a freezing function. Since both the guide rail base 1 and the guide rail bracket 2 extend upward obliquely from the front side of the box body 5 to the rear side of the box body 5, when the user pulls out the box body 5, the box body 5 is lifted upward accordingly, which can reduce the bending amplitude of the user, so as to facilitate the user to take and place items in the box body 5, and is beneficial to improving the user experience.
[0093] As Figure 2 shown, the guide rail bracket 2 is used to be mounted on the box body 5. When the user pulls and pushes the box body 5, the guide rail bracket 2 can slide relative to the guide rail base 1 in the first direction.
[0094] As Figure 2 and Figure 3As shown, the slide rail device is arranged to slope upward in the front-to-back direction. When the box body 5 is pulled out obliquely upward in the front-to-back direction, due to the certain weight of the box body 5, under the action of gravity, the box body 5 will give a downward component force to the guide rail bracket 2. Since the limiting member 31 can move relative to the guide rail bracket 2 in the second direction in the released state, under the cooperation of the limiting member 31 and the first wall surface 13, the guide rail bracket 2 will not slide downward due to the gravity of the box body 5. Thus, the box body 5 can be stopped at the position required by the user to improve the user experience.
