[0027] In existing storage devices such as refrigerators and wine cabinets, in order to ensure the stability of the drawer connection and meet the requirements of disassembly, the two ends of the drawer along the sliding direction are fixed to the slide rail by buckles, and a lever is provided to release the buckles. The overall structure is complicated, and users need to move the lever to release the buckles in order to remove the drawer, which is inconvenient.

[0028] Therefore, referring to Figures 1 to 8 As shown, the first aspect of this utility model provides a drawer assembly for use in storage devices. Generally, the storage device includes a housing with an inner cavity, and the drawer assembly is installed in the inner cavity for storing items. The storage device here can be a refrigerator, wine cabinet, display case, etc.

[0029] Reference Figure 1 As shown, it can be understood that the drawer assembly includes a drawer body 100, a first slide rail 200, and a second slide rail 300. Specifically, the drawer body 100 and the housing are defined as either a first component or a second component.

[0030] Reference Figure 1 and Figure 2 As shown, it can be understood that in some embodiments, the first slide rail 200 is disposed on the housing and the second slide rail 300 is disposed on the drawer body 100, that is, the housing is the first component and the drawer body 100 is the second component.

[0031] Reference Figure 1 As shown, it can be understood that the first slide rail 200 and the housing can be detachably connected via screws, clips, etc., or the first slide rail 200 and the housing can be an integral structure. Similarly, the second slide rail 300 and the drawer body 100 can also be detachably connected via screws, clips, etc., or the second slide rail 300 and the drawer body 100 can be an integral structure. In this embodiment, the first slide rail 200 is detachably connected to the housing via screws, and the second slide rail 300 and the drawer body 100 are an integral structure.

[0032] Reference Figure 1 As shown, the housing has an open inner cavity facing forward. The first slide rail 200 is mounted on the inner wall of the cavity and arranged in the front-to-back direction. Correspondingly, the second slide rail 300 is located on the outer wall of the drawer body 100 and arranged in the front-to-back direction. The second slide rail 300 and the first slide rail 200 slide in the front-to-back direction, thereby enabling the drawer body 100 to slide in the front-to-back direction and be mounted on the housing. Generally, the left and right sides of the drawer body 100 are supported by the housing through the combination of the first slide rail 200 and the second slide rail 300 to ensure the sliding stability of the drawer body 100.

[0033] The following describes in detail the structure of the combination of the first slide rail 200 and the second slide rail 300 on one side of the drawer body 100, based on an embodiment in which the first slide rail 200 is disposed on the housing and the second slide rail 300 is disposed on the drawer body 100.

[0034] Reference Figures 2 to 4 As shown, the first slide rail 200 is provided with a slide groove 210 and a first clearance groove 220. The slide groove 210 is arranged in the front-to-back direction, and the slide groove 210 has an opening 211 at least at its front end. The first clearance groove 220 is disposed on the upper side wall of the slide groove 210 and located at the opening 211. That is, in the vertical direction, the width of the opening 211 is greater than the minimum width of the slide groove 210.

[0035] Reference Figure 3 , Figure 5 and Figure 6 As shown, it can be understood that the second slide rail 300 passes through the opening 211 into the slide groove 210 and is slidably installed in the slide groove 210 in the front-back direction. This achieves a sliding engagement between the second slide rail 300 and the first slide rail 200, allowing the drawer body 100 to be slidably installed in the housing in the front-back direction. It is also easy to understand that the second slide rail 300 can extend out of the slide groove 210 from the opening 211 and can disengage from the first slide rail 200 through the opening 211. A second clearance groove 310 is provided on the lower end face of the second slide rail 300. The second clearance groove 310 is located at the end of the second slide rail 300 facing the rear end of the slide groove 210; that is, the second clearance groove 310 is located on the lower end face of the rear end of the second slide rail 300. Thus, in the vertical direction, the thickness of the rear end of the second slide rail 300 is less than the maximum thickness of the second slide rail 300.

[0036] Reference Figure 2 and Figure 3 As shown, it can be understood that at least one side of the drawer body 100, on its left and right sides, is provided with a first limiting part 110. The first limiting part 110 is configured as a protruding structure and is located above the second slide rail 300. The first limiting part 110 is configured to limit the sliding direction of the drawer body 100 on the second slide rail 300. For example, when the drawer body 100 is pulled out to its maximum opening limit during the opening process, the first limiting part 110 restricts the drawer body 100 from further disengaging from the housing. When the drawer body 100 is in the closed state, the first limiting part 110 limits the drawer body 100 to prevent it from becoming loose or accidentally sliding out. Generally, the first limiting part 110 is located near the rear end of the drawer body 100 to increase the travel of the drawer body 100 and facilitate the user's access to items.

[0037] Therefore, by providing a first limiting part 110 on the drawer body 100, it is possible to prevent the drawer body 100 from detaching from the housing and to prevent the drawer body 100 from becoming loose or accidentally sliding out, which helps to ensure the connection stability of the drawer body 100.

[0038] Reference Figures 2 to 6As shown, it can be understood that the first clearance groove 220 and the second clearance groove 310 are configured to provide clearance when they approach each other, allowing one of the first slide rail 200 and the second slide rail 300 to tilt upward relative to the other, and causing the first limiting part 110 to release its restriction on the drawer body 100. Specifically, during the process of opening the drawer body 100, when the drawer body 100 is pulled out, the first clearance groove 220 and the second clearance groove 310 approach each other in the sliding direction of the drawer body 100. When the drawer body 100 is pulled out to the maximum opening limit position, the first limiting part 110 restricts the drawer body 100 from being pulled out further. When the drawer body 100 is pulled out to its maximum opening limit, the projections of the opposite ends of the first clearance groove 220 and the second clearance groove 310 on the horizontal plane in the sliding direction of the drawer body 100 coincide, that is, the projections of the rear end of the first clearance groove 220 and the front end of the second clearance groove 310 on the horizontal plane coincide; or, the projections of the first clearance groove 220 and the second clearance groove 310 on the horizontal plane partially coincide, so that the first clearance groove 220 and the second clearance groove 310 can provide clearance for the second slide rail 300 during the upward deflection relative to the first slide rail 200. The upward deflection of the second slide rail 300 relative to the first slide rail 200 can also be understood as the second slide rail 300 rotating upward around the central axis (arranged in the left-right direction) located at the front end of the second clearance groove 310. Therefore, the user can lift the front end of the drawer body 100 upwards, that is, the drawer body 100 tilts upwards or rotates upwards, causing the first limiting part 110 on the drawer body 100 to shift upwards or downwards, thereby releasing the first limiting part 110 from limiting the drawer body 100, and the user can then take out the drawer body 100, thus completing the disassembly of the drawer body 100. The operation is convenient and facilitates the maintenance of the drawer body 100 or the inside of the shell, or the cleaning of the drawer body 100.

[0039] When installing the drawer body 100, tilt the drawer body 100 so that its front end is higher than its rear end. Then, insert the rear end of the second slide rail 300 into the slide groove 210 of the first slide rail 200 through the opening 211. Next, tilt the drawer body 100 downwards until it is horizontal. Then, push the drawer body 100 into the inner cavity of the housing to complete the installation of the drawer body 100, making it convenient for users to replace drawers. The drawer body 100 has a simple disassembly and assembly structure, is easy to operate, and is easy to manufacture and assemble.

[0040] Understandably, along the sliding direction of the drawer body 100, if the first limiting part 110 is located behind the front end of the second clearance groove 310, when the drawer body 100 swings upward (i.e., the front end is lifted upward), the first limiting part 110 shifts downward; if the first limiting part 110 is located in front of the front end of the second clearance groove 310, when the drawer body 100 swings upward (i.e., the front end is lifted upward), the first limiting part 110 shifts upward. In this embodiment, the first limiting part 110 is located in front of the front end of the second clearance groove 310.

[0041] Reference Figure 3 and Figure 4 As shown, it can be understood that the groove wall of the first clearance groove 220 is configured as a first inclined surface 221, and the upper end of the first inclined surface 221 is closer to the opening 211 of the slide rail 210 than the lower end of the first inclined surface 221. That is, the outline of the first clearance groove 220 in a cross section perpendicular to the left and right direction is approximately triangular, and the front end of the first inclined surface 221 is higher than the rear end of the first inclined surface 221. Therefore, when the drawer body 100 tilts upward, the structure in the second slide rail 300 located in front of the front end of the second clearance groove 310 tilts upward, and the first clearance groove 220 can avoid the second slide rail 300, so as to disassemble or install the drawer body 100. The structure of the first clearance groove 220 is simple and easy to manufacture.

[0042] Reference Figure 3 and Figure 6 As shown, it can be understood that, similarly, the groove wall of the second clearance groove 310 is configured as a second inclined surface 311, and the lower end of the second inclined surface 311 is closer to the opening 211 of the slide rail 210 than the upper end of the second inclined surface 311. That is, the cross-sectional profile of the second clearance groove 310 in a section perpendicular to the left-right direction is approximately triangular, and the front end of the second inclined surface 311 is lower than its rear end. Therefore, when the drawer body 100 tilts upwards, the structure in the second slide rail 300 located behind the front end of the second clearance groove 310 tilts downwards, allowing the second clearance groove 310 to avoid the second slide rail 300, facilitating the disassembly or installation of the drawer body 100. The second clearance groove 310 has a simple structure and is easy to manufacture.

[0043] It is understood that in other embodiments, the walls of the first clearance groove 220 and the second clearance groove 310 can also be curved surfaces or other curved surfaces, or they can be composed of two planes at an angle to each other. For example, in a cross-section perpendicular to the left-right direction, the cross-sectional profiles of the first clearance groove 220 and the second clearance groove 310 are rectangular, trapezoidal, etc. It is sufficient that the first clearance groove 220 and the second clearance groove 310 can provide clearance; there is no specific limitation on the wall structure of the first clearance groove 220 and the second clearance groove 310, and the structural form of the wall of the first clearance groove 220 and the second clearance groove 310 can be different.

[0044] Reference Figure 2 and Figure 3 As shown, it can be understood that, in order to prevent the drawer body 100 from further detaching from the housing when it is pulled out to its maximum opening limit during the opening process, the first limiting part 110 also provides a second limiting part 230. Specifically, the second limiting part 230 is a block structure, and its upper and / or lower sides can be clearance spaces. The second limiting part 230 is located on the upper side of the first sliding rail 200 and close to one end of the opening 211 of the slide groove 210. When the second sliding rail 300 slides in conjunction with the first sliding rail 200, that is, when the drawer body 100 is slidably disposed in the housing and the drawer body 100 is not tilted upwards, on the projection plane perpendicular to the sliding direction of the drawer body 100, the projection of the first limiting part 110 and the projection of the second limiting part 230 partially or completely overlap. Thus, when the drawer body 100 is pulled out to its maximum opening limit, the first limiting part 110 abuts against the rear side of the second limiting part 230, thereby limiting the drawer body 100. The second limiting part 230 and the first limiting part 110 cooperate to restrict the drawer body 100 from being pulled out, preventing the drawer body 100 from detaching from the housing and improving safety in use.

[0045] Reference Figure 2 and Figure 3 As shown, it can be understood that the first limiting part 110 and the second limiting part 230 are configured to be offset vertically when one of the first slide rail 200 and the second slide rail 300 is tilted upward relative to the other. Therefore, when the drawer body 100 is tilted upward, the first limiting part 110 shifts downward or upward, causing the first limiting part 110 and the second limiting part 230 to be offset vertically. This allows the first limiting part 110 to pass over the second limiting part 230 when the drawer body 100 is further removed, thus avoiding the limiting effect of the second limiting part 230. In other words, the limitation on the drawer body 100 is released, allowing the user to easily remove the drawer body 100, making operation convenient. In this embodiment, when the drawer body 100 is tilted upward, the first limiting part 110 shifts upward to release the limitation on the drawer body 100.

[0046] Reference Figures 2 to 4As shown, it can be understood that, in order to achieve the purpose of limiting the drawer body 100 by the first limiting part 110 to prevent the drawer body 100 from becoming loose or accidentally sliding out when the drawer body 100 is in the closed state, the first slide rail 200 is also provided with a third limiting part 240. The third limiting part 240 is located on the upper side of the first slide rail 200 and away from the opening 211 of the slide groove 210. The third limiting part 240 and the second limiting part 230 are arranged at intervals in the sliding direction of the drawer body 100, and the third limiting part 240 is located behind the second limiting part 230. The third limiting part 240 includes a limiting groove 241 and a protrusion 242, wherein the limiting groove 241 passes through the drawer body 100 in the sliding direction, and the protrusion 242 is located on the upper side of the limiting groove 241 and protrudes downward. When the second slide rail 300 and the first slide rail 200 are in sliding engagement, that is, when the drawer body 100 is slidably disposed in the housing and the drawer body 100 is not tilted upwards, and when the first limiting part 110 is not directly below the protrusion 242, on the projection plane perpendicular to the sliding direction of the drawer body 100, the projection of the protrusion 242 coincides with a portion of the projection of the first limiting part 110, and the first limiting part 110 is configured to pass through the limiting groove 241. Therefore, during the process of closing the drawer body 100, the first limiting part 110 can pass through the limiting groove 241 from front to back, and at the same time, the first limiting part 110 passes over the protrusion 242. Generally, the third limiting part 240 has a certain elasticity in the vertical direction. During the process of the first limiting part 110 passing through the limiting groove 241, the first limiting part 110 drives the protrusion 242 to shift upward. After the first limiting part 110 passes the protrusion 242, the protrusion 242 returns to its downward position, so that the first limiting part 110 abuts against the rear side of the protrusion 242. At this time, the drawer body 100 is in a fully closed state. Therefore, without applying a pulling force to the drawer body 100, the cooperation between the protrusion 242 and the first limiting part 110 can restrict the drawer body 100 from moving out of the inner cavity of the housing, effectively preventing the drawer body 100 from loosening or accidentally sliding out, thus improving safety. When the user needs to open the drawer body 100, only a certain pulling force needs to be applied to the drawer body 100 to make the first limiting part 110 pass the protrusion 242 from back to front, so that the drawer body 100 can be easily pulled out, making the operation convenient.

[0047] Reference Figure 3 and Figure 7As shown, it can be understood that, to improve the smoothness of sliding between the first slide rail 200 and the second slide rail 300, the drawer assembly also includes a sliding module 400. Specifically, the sliding module 400 is installed between the first slide rail 200 and the second slide rail 300. The sliding module 400 includes a retainer 410 and a plurality of rolling elements 420. The retainer 410 is slidably installed in the slide groove 210 of the first slide rail 200 in the front-back direction. The plurality of rolling elements 420 are rotatably installed on the retainer 410, and the plurality of rolling elements 420 are respectively disposed between the upper side wall of the slide groove 210 of the first slide rail 200 and the upper end face of the second slide rail 300, and between the lower side wall of the slide groove 210 of the first slide rail 200 and the lower end face of the second slide rail 300. Therefore, the first slide rail 200 and the second slide rail 300 are slidably engaged by the retainer 410 sliding relative to the first slide rail 200 and the rolling element 420 rolling between the first slide rail 200 and the second slide rail 300. Generally, during the opening or closing of the drawer body 100, the moving speed of the retainer 410 is less than the moving speed of the drawer body 100, that is, the first stroke of the retainer 410 is less than the second stroke of the drawer body 100, for example, the first stroke is half of the second stroke, thus reducing the sliding resistance of the drawer body 100; at the same time, the rolling element 420 can effectively reduce the friction between the first slide rail 200 and the second slide rail 300, further reducing the sliding resistance of the drawer body 100, thereby making the drawer body 100 move smoothly and convenient for user use.

[0048] Understandably, in order to ensure the reliability of the connection between the rolling element 420 and the first slide rail 200 and the second slide rail 300, the upper side wall of the slide groove 210, the upper end face of the second slide rail 300, the lower side wall of the slide groove 210 of the first slide rail 200, and the lower end face of the second slide rail 300 are respectively provided with grooves. The grooves are arranged in the front-back direction, and part of the structure of the rolling element 420 is accommodated in the grooves.

[0049] It is understandable that the rolling element 420 can be a ball structure, such as a steel ball or a plastic ball, or part of the rolling element 420 can be a steel ball and the other part can be a plastic ball.

[0050] Reference Figure 3 and Figure 7 As shown, the cage 410 includes a mounting portion 411 and two connecting portions 412. Specifically, the two connecting portions 412 are respectively connected to the upper and lower ends of the mounting portion 411, and a portion of the structure of the connecting portion 412 is suspended relative to the mounting portion 411. Multiple rolling elements 420 are rotatably mounted on the two connecting portions 412, and a second slide rail 300 is located between the two connecting portions 412. Typically, the cage 410 is made of plastic, and the suspended structure of the connecting portion 412 can bend vertically under external force and return to its original shape after the external force is removed.

[0051] Reference Figure 4 and Figure 7 As shown, the first slide rail 200 is provided with a slot 280, which is located on the side wall of the slide groove 210 and arranged in the front-to-back direction. The mounting part 411 engages with the slot 280 and can slide along the slot 280 to prevent the retainer 410 from disengaging from the first slide rail 200 and to allow the retainer 410 to slide in cooperation with the first slide rail 200. The slot 280 is approximately located at the middle position of the first slide rail 200 in the front-to-back direction. Generally speaking, the length of the slot 280 in the front-to-back direction is the first stroke of the retainer 410.

[0052] Therefore, by providing connecting portions 412 that can be bent in the vertical direction at both the upper and lower ends of the retainer 410, when the drawer body 100 is pulled out to its maximum opening limit, the retainer 410 is located near the opening 211 of the slide rail 210. When the drawer body 100 is tilted upwards, part of the structure of the connecting portion 412 located below the first clearance groove 220 will bend upwards along with the second slide rail 300, preventing the retainer 410 from obstructing the upward tilting of the drawer body 100 and improving reliability. Thus, the second slide rail 300 can easily detach from the retainer 410 and move out from the opening 211 of the slide rail 210, thereby realizing the disassembly of the drawer body 100, which is convenient to operate.

[0053] Understandably, during the process of closing the drawer body 100, both the drawer body 100 and the retainer 410 move from front to back. There may be slippage between the rolling element 420 and the second slide rail 300, causing the retainer 410 to move at a speed lower than the normal speed. As a result, when the drawer body 100 is in the fully closed position, the retainer 410 has not yet moved to the end (i.e., the rear end) away from the opening 211 of the slide rail 210 within the first stroke. In other words, the retainer 410 has not reset, affecting the smoothness of the drawer body 100 when it is reopened.

[0054] Therefore, referring to Figure 2 and Figure 6As shown, it can be understood that the second slide rail 300 is also provided with a fourth limiting part 320. The fourth limiting part 320 is a protruding structure and is provided on the upper end surface or the lower end surface of the second slide rail 300, or the fourth limiting part 320 is provided on both the upper end surface and the lower end surface of the second slide rail 300. The fourth limiting part 320 is located at the end of the second slide rail 300 away from the second clearance groove 310, that is, close to the front end of the second slide rail 300. In this embodiment, the fourth limiting part 320 is located at the front end of the groove on the second slide rail 300. When the second slide rail 300 and the first slide rail 200 are in sliding engagement, that is, when the drawer body 100 is slidably disposed on the housing and the drawer body 100 is not tilted upward, on the projection surface perpendicular to the sliding direction of the drawer body 100, the projection of the fourth limiting part 320 coincides with the projection of the sliding module 400. Specifically, the projection of the fourth limiting part 320 coincides with the projection of the rolling element 420. Therefore, during the process of closing the drawer body 100, the fourth limiting part 320 can push the sliding module 400 to move.

[0055] Reference Figure 2 and Figure 6 As shown, it can be understood that the fourth limiting part 320 is configured to move the retainer 410 to the end away from the opening 211 of the slide rail 210 within the first stroke. Therefore, during the closing of the drawer body 100, when the rolling element 420 slips relative to the second slide rail 300, the fourth limiting part 320 first abuts against the rolling element 420 closest to the fourth limiting part 320, while the retainer 410 has not yet moved to the end away from the opening 211 of the slide rail 210 within the first stroke. As the drawer body 100 is further closed, the fourth limiting part 320 pushes the retainer 410 to move synchronously with the drawer body 100 until the drawer body 100 is fully closed. At this point, the retainer 410 moves to the end away from the opening 211 of the slide rail 210 within the first stroke, thus resetting the retainer 410 to ensure that the drawer body 100 can be smoothly pulled out again for convenient use.

[0056] It is understandable that during the process of opening the drawer body 100, both the drawer body 100 and the retainer 410 move from back to front. There may also be slippage between the rolling element 420 and the second slide rail 300, which may cause the retainer 410 to move at a speed lower than the normal speed. As a result, when the drawer body 100 is in the maximum opening limit position, the retainer 410 has not yet moved to the end (i.e., the front end) of the opening 211 near the slide rail 210 within the first stroke. In other words, the retainer 410 is not in place, which affects the smoothness of the movement of the drawer body 100 when closing the drawer body 100.

[0057] Therefore, referring to Figure 3 , Figure 6 and Figure 8As shown, it can be understood that the second slide rail 300 is also provided with an elastic part 330. The elastic part 330 is an elastic snap-fit ​​structure and is provided on the upper end surface of the second slide rail 300 or on the side of the second slide rail 300 facing the first slide rail 200. The elastic part 330 is located at one end of the second slide rail 300 near the second clearance groove 310, that is, at the rear end of the second slide rail 300. In this embodiment, in the sliding direction of the drawer body 100, the elastic part 330 is located within the range of the groove on the second slide rail 300 and near the rear end of the groove. When the second slide rail 300 and the first slide rail 200 are in sliding engagement, that is, when the drawer body 100 is slidably disposed on the housing and the drawer body 100 is not tilted upward, on the projection plane perpendicular to the sliding direction of the drawer body 100, the projection of the elastic part 330 coincides with the projection of the sliding module 400, specifically, the projection of the elastic part 330 coincides with the projection of the retainer 410. Therefore, during the opening of the drawer body 100, the elastic part 330 can push the sliding module 400 to move. Simultaneously, under external force, the elastic part 330 can deform, and after the external force is removed, the elastic part 330 can return to its original shape. Therefore, during assembly, the elastic part 330 can be prevented from obstructing the insertion of the second slide rail 300 between the two connecting parts 412 of the retainer 410.

[0058] Reference Figure 3 , Figure 6 and Figure 8 As shown, it can be understood that the elastic part 330 is configured to move the retainer 410 to one end near the opening 211 of the slide rail 210 within the first stroke. Therefore, during the opening of the drawer body 100, when the rolling element 420 slips relative to the second slide rail 300, the elastic part 330 first contacts the retainer 410. Before the retainer 410 moves to one end near the opening 211 of the slide rail 210 within the first stroke, as the drawer body 100 is further closed, the elastic part 330 pushes the retainer 410 to move synchronously with the drawer body 100 until the drawer body 100 is in the maximum opening limit position. At this point, the retainer 410 moves to one end near the opening 211 of the slide rail 210 within the first stroke, thus moving the retainer 410 into position to ensure smooth closing of the drawer body 100 for convenient use.

[0059] Reference Figure 2 and Figure 4As shown, it can be understood that during the closing of the drawer body 100, when the retainer 410 moves to the end (i.e., the rear end) away from the opening 211 of the slide groove 210 within the first stroke, although the slot 280 can limit the sliding module 400, to further improve the reliability of the limit, the first slide rail 200 is also provided with a fifth limiting part 250. The fifth limiting part 250 is a protruding structure and is provided on the upper or lower groove wall of the slide groove 210, or the upper and lower groove walls of the slide groove 210 are respectively provided with the fifth limiting part 250. The fifth limiting part 250 is located at the end of the first slide rail 200 away from the opening 211 of the slide groove 210, for example, the fifth limiting part 250 is located at the rear end of the groove on the first slide rail 200. With the second slide rail 300 slidingly engaged with the first slide rail 200, i.e., the drawer body 100 is slidably disposed on the housing and the drawer body 100 is not tilted upwards, on the projection surface perpendicular to the sliding direction of the drawer body 100, the projection of the fifth limiting part 250 coincides with the projection of the sliding module 400. Specifically, the projection of the fifth limiting part 250 coincides with the projection of the retainer 410. The fifth limiting part 250 is configured to restrict the retainer 410 from moving beyond the first stroke along the direction away from the opening 211 of the slide groove 210. Therefore, during the closing of the drawer body 100, when the rolling element 420 slips relative to the first slide rail 200, the moving speed of the retainer 410 is greater than the normal moving speed. When the drawer body 100 is not fully closed, the retainer 410 moves to the end of the first stroke away from the opening 211 of the slide rail 210. As the drawer body 100 is further closed, the retainer 410 remains stationary under the limiting action of the fifth limiting part 250 until the drawer body 100 is fully closed. This prevents the retainer 410 from moving out of the first stroke, improving reliability.

[0060] It is understandable that, for the combination of the first slide rail 200 and the second slide rail 300 located on the left and right sides of the drawer body 100, there will be a large amount of shaking during the movement of the drawer body 100 because there is no synchronous structure on the left and right sides.

[0061] Therefore, referring to Figure 3 and Figure 4 As shown, the first slide rail 200 is also provided with a first protrusion 260. The first protrusion 260 is disposed on the side wall of the slide groove 210 and located at the opening 211. The first protrusion 260 is arranged in the vertical direction and protrudes towards the second slide rail 300 along the width direction of the drawer body 100. The cross-section of the first protrusion 260 can be semi-circular, rectangular, etc. Therefore, by providing the first protrusion 260, the lateral sway of the drawer body 100 can be reduced, and the movement stability of the drawer body 100 can be improved.

[0062] It is understandable that, due to the gap between the first slide rail 200 and the second slide rail 300 in the vertical direction, when the drawer body 100 is pulled out, when the center of gravity of the drawer body 100 moves to the outside of the shell, the front end of the drawer body 100 will sink and the rear end will tilt upward, which will cause the rolling element 420 closest to the opening 211 of the slide groove 210 to bear a large force and be damaged.

[0063] Therefore, referring to Figure 3 and Figure 4 As shown, it can be understood that the first slide rail 200 is also provided with a second protrusion 270. The second protrusion 270 is disposed on the lower side wall of the slide groove 210 and located at the opening 211. The second protrusion 270 is arranged in the left-right direction and protrudes upward. The longitudinal section of the second protrusion 270 can be semi-circular, rectangular, etc. Therefore, by providing the second protrusion 270, when the drawer body 100 is pulled out, the second protrusion 270 can provide an upward support force to the drawer body 100, thereby reducing the amount of sinking of the front end of the drawer body 100. At the same time, it can share the force borne by the rolling element 420 closest to the opening 211 of the slide groove 210, improving stability and reliability.

[0064] In other embodiments, it is understood that the first slide rail 200 may be disposed on the drawer body 100, and the second slide rail 300 may be disposed on the housing; that is, the drawer body 100 is the first component, and the housing is the second component. Compared to the aforementioned embodiments, this embodiment can be understood as rotating the combination of the first slide rail 200 and the second slide rail 300 180° in the front-to-back direction, thereby swapping the installation positions of the first slide rail 200 and the second slide rail 300.

[0065] The storage device according to a second aspect of this utility model includes a housing and a drawer assembly according to a first aspect of this utility model, the drawer assembly being mounted on the housing. The storage device can be a refrigerator, wine cabinet, display case, etc.

[0066] Since the storage device adopts all the technical solutions of the drawer assembly of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments.

[0067] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
