[0055] Hereinafter, a drawer assembly 100 and an oven having the same according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0056] Reference Figures 1-13 As shown, the drawer assembly 100 according to the embodiment of the present invention may include: a drawer body 10 and a drawer bottom shell assembly 20. The oven according to the embodiment of the present invention includes the drawer assembly 100 according to the embodiment of the present invention.

[0057] Specifically, if Figures 1-8 As shown, a receiving cavity 101 may be provided in the drawer body 10, and the receiving cavity 101 may be used to receive items. In an embodiment where the drawer assembly 100 is used in an oven, a grill, a grilling plate, or other containers for holding food may be placed in the receiving cavity 101, or the receiving cavity 101 may be used to directly place food for grilling, or the drawer assembly 100 may be used to store common items used in the oven (such as containers, grilling ingredients, etc.). Figures 9-13 As shown, the drawer body 10 can be pulled relative to the drawer bottom shell assembly 20, and the pulling direction can be Figure 10 and Figure 12The front-to-back direction shown in FIG. 1 is for easy access to the contents and cleaning of the accommodating cavity 101 .

[0058] In an embodiment of the present invention, Figure 3 、 Figure 14-16 As shown, the two oppositely disposed side walls of the drawer body 10 (such as Figure 14 The left and right side walls (shown in the figure) can each be provided with a sliding engagement portion 11, which defines a hooking slot 112, the bottom of which is open. In some embodiments, the sliding engagement portion 11 can be provided at the top of the side wall of the drawer body 10 to facilitate processing and molding, and to facilitate positioning the majority of the drawer body 10 within the drawer bottom shell assembly 20, making the structure more compact.

[0059] The present invention imposes no particular restrictions on the specific structure of the sliding engagement portion 11, as long as it can define the hooking groove 112. In some embodiments, the sliding engagement portion 11 can be a sheet metal flange structure formed by sheet metal processing; in other embodiments, the sliding engagement portion 11 can be a strip rib, and the hooking groove 112 can be a groove formed by a process such as turning.

[0060] In an embodiment of the present invention, the connection structure between the sliding fitting portion 11 and the drawer body 10 can be flexibly set according to actual conditions. In some embodiments, the sliding fitting portion 11 can be detachably mounted on the drawer body 10 by means of fasteners, snap connections, etc., to facilitate later maintenance and replacement; in other embodiments, the sliding fitting portion 11 can be welded and fixed to the drawer body 1011 to improve the connection strength; in still other embodiments, the sliding fitting portion 11 can be integrally formed in the drawer body 10, and the sliding fitting portion 11 does not need to be assembled, the connection is firm and reliable, and the structure of the sliding fitting portion 11 is simple and easy to process. In some specific embodiments, such as Figure 3 As shown, the sliding fitting portion 11 can be formed by bending the side wall of the drawer body 10 upward, outward and then downward, so that the sliding fitting portion 11 can be integrally formed with the drawer body 10 .

[0061] like Figures 18-24 As shown, the drawer bottom shell assembly 20 may include a bottom shell 21 and a support slide 22. There may be two support slides 22, and the two support slides 22 are respectively fixed on two opposite inner side walls of the bottom shell 21. Figure 18 Each support slide 22 may be defined with a sliding groove 221, and the top of the sliding groove 221 is open, so that the sliding fitting portion 11 can be as shown. Figure 2-Figure 8 The hook is shown hooked in the sliding slot 221 on the corresponding side.

[0062] Specifically, if Figure 3 and Figure 5As shown, a portion of each supporting sliding member 22 can extend into the hooking groove 112 of the corresponding sliding fitting portion 11, and a portion of each sliding fitting portion 11 can extend into the sliding groove 221 of the corresponding supporting sliding member 22. By setting the above structure, each sliding fitting portion 11 can be slidably fitted with the supporting sliding member 22 located on the corresponding side, so that the sliding fitting portion 11 can slide along the sliding groove 221, thereby realizing the pulling and drawing of the drawer body 10.

[0063] Through the hooking cooperation between the sliding fitting part 11 and the supporting sliding member 22, the side groove wall of the sliding groove 221 can limit the sliding fitting part 11 in the horizontal direction, and the side groove wall of the hooking groove 112 can limit the supporting sliding member 22 in the horizontal direction, so that the relative position of the drawer body 10 and the drawer bottom shell assembly 20 in the horizontal direction is stable, the drawer body 10 is not prone to deflection and shaking, and the pulling and drawing are smoother.

[0064] In the related art, drawers use ball bearing slide rails. When the drawers are used frequently, the balls are easily stuck and fall off, which causes the slide rails to be easily damaged, resulting in a short service life and high maintenance costs.

[0065] The present invention utilizes a sliding engagement portion 11 and a supporting slide 22 to form a simulated sliding structure, achieving a slide rail function. This eliminates the need for a fragile ball bearing structure, making the sliding structure less susceptible to damage such as jamming and falling off. This increases the operating life of the drawer assembly 100 and reduces maintenance frequency and costs. In embodiments where the drawer assembly 100 is used in an oven, particularly a large, freestanding oven, the drawer assembly 100 is frequently used. Using the drawer assembly 100 of the present invention makes the sliding structure less susceptible to damage, reducing subsequent oven maintenance costs.

[0066] Furthermore, the sliding engagement portion 11 and the supporting slide 22 have a simple structure and are easy to assemble. Under the weight of the drawer body 10 and the weight of the contents in the accommodating cavity 101, a portion of the sliding engagement portion 11 can be stably positioned within the sliding groove 221, and the sidewalls along the hooking groove 112 can engage with the sidewalls of the sliding groove 221, preventing the sliding engagement portion 11 from disengaging from the supporting slide 22 and ensuring reliable position retention.

[0067] In an embodiment of the present invention, at least one sliding fitting portion 11 may be provided on each side wall of the drawer body 10 .

[0068] Among them, in an embodiment with a sliding fitting, as Figure 14 and Figure 15As shown, the sliding fitting can extend along the pulling direction of the drawer body 10, so that the drawer body 10 is evenly stressed, the movement is more stable, and the structural strength is high, and it can withstand the heavier drawer body 10 and the contents in the accommodating cavity 101, especially when the drawer body 10 is pulled out to a larger size, the stability of the drawer body 10 can still be guaranteed. In the embodiment where the sliding fitting portion 11 is formed by bending the side wall of the drawer body 10, the integral sliding fitting is more effective in improving the structural strength of the drawer body 10.

[0069] In an embodiment in which a plurality of sliding fitting parts 11 are provided, on the one hand, more stable and reliable support can be provided to the drawer body 10 in the pulling direction, and the length of each sliding fitting part 11 along the pulling direction can be smaller to reduce the sliding friction resistance, and on the other hand, it is convenient for the disassembly and assembly of the sliding fitting part 11 and the sliding groove 221.

[0070] According to the drawer assembly 100 of the embodiment of the present invention, the sliding rail function is realized by the cooperation of the sliding fitting part 11 and the supporting sliding member 22, eliminating the ball bearing structure, making it less prone to damage, increasing the service life, reducing maintenance costs, and having a simple structure and easy assembly, thereby reducing production costs.

[0071] Since the drawer assembly 100 according to the embodiment of the present invention has the above-mentioned beneficial technical effects, the oven according to the embodiment of the present invention realizes the sliding rail function through the cooperation of the sliding fitting part 11 and the supporting sliding member 22, eliminating the ball bearing structure, making it less prone to damage, increasing the service life, reducing maintenance costs, and having a simple structure and easy assembly, thereby reducing production costs.

[0072] In some embodiments of the present invention, Figures 18-24 As shown, at least one supporting sliding member 22 may be provided with a first limiting protrusion 222 and a second limiting protrusion 223, and in the pulling direction of the drawer body 10, the first limiting protrusion 222 and the second limiting protrusion 223 may be spaced apart. Figure 6-Figure 8 As shown, each supporting sliding member 22 is provided with a first limiting protrusion 222 and a second limiting protrusion 223 to limit the pulling and pulling stroke of the drawer body 10 from both lateral sides of the drawer body 10, so that the drawer body 10 is not prone to deflection when pulled to the extreme position.

[0073] like Figure 4-10 As shown, a limit fitting member 113 may be provided on the sliding fitting portion 11. When the drawer body 10 is pulled out, the limit fitting member 113 may engage with the first limit protrusion 222 or the second limit protrusion 223, thereby limiting the pulling stroke of the drawer body 10 and preventing the sliding fitting portion 11 from falling out of the sliding groove 221 when the drawer body 10 is pulled out, thereby making the drawer body 10 safer to use.

[0074] Specifically, if Figures 6-10 and Figures 18-24 As shown, the first limiting protrusion 222 is located in front of the second limiting protrusion 223. When the drawer body 10 is pulled out until the limiting fitting 113 abuts against the first limiting protrusion 222, it indicates that the drawer body 10 is pulled out to the limit position; when the drawer body 10 is pushed until the limiting fitting 113 abuts against the second limiting protrusion 223, it indicates that the drawer body 10 is pushed to the limit position and closed in place.

[0075] In some embodiments of the present invention, Figure 5 、 Figure 7 、 Figure 21 As shown, the first limiting protrusion 222 and the second limiting protrusion 223 can be arranged on the bottom wall of the supporting sliding member 22, and the limiting fitting member 113 can be arranged on the side wall of the portion of the sliding fitting portion 11 extending into the sliding groove 221, so that the projections of the limiting fitting member 113, the first limiting protrusion 222 and the second limiting protrusion 223 along the pulling direction at least partially overlap, thereby realizing reliable pulling stroke limitation.

[0076] Of course, the arrangement positions of the first limiting protrusion 222 and the second limiting protrusion 223 include but are not limited to the above. In some embodiments, the first limiting protrusion 222 and the second limiting protrusion 223 can also be arranged on the side wall of the supporting sliding member 22, and can also cooperate with the limiting matching member 113 to achieve the stroke limit of the drawer body 10.

[0077] In some embodiments, as Figure 5 As shown, the side wall of the protruding portion of the sliding fitting portion 11 can be located between the limiting protrusions (including the first limiting protrusion 222 and the second limiting protrusion 223) and the side groove wall of the sliding groove 221, and the limiting fitting member 113 can be located between the protruding portion of the sliding fitting portion 11 and the side groove wall of the sliding groove 221, thereby reducing the gap between the sliding fitting portion 11 and the side groove wall of the sliding groove 221, making the drawer body 10 less likely to shake in the lateral direction. In some embodiments, the limiting fitting member 113 can be located outside the protruding portion of the sliding fitting portion 11.

[0078] In some embodiments, the limiting protrusion can be fixed to the wall surface of the supporting sliding member 22 by welding, bonding, etc., which not only plays a limiting role but also can improve the structural strength of the supporting sliding member 22; in other embodiments, such as Figure 7 As shown, at least one of the first limiting protrusion 222 and the second limiting protrusion 223 can be integrally formed on the supporting sliding member 22, without the need for assembly, easy to process and form, and has a simpler structure and a more secure connection.

[0079] In some specific embodiments, Figure 7As shown, a portion of the bottom wall of the support slider 22 can be separated from the rest of the support slider 22 and then bent upward. The first limiting protrusion 222 and the second limiting protrusion 223 can both be bent in this manner. In other words, the limiting protrusions are integrally formed on the support slider 22. On the one hand, no additional parts are required to form the limiting protrusions, which reduces the number of parts and raw materials used, thereby reducing production costs and eliminating the assembly process of installing and fixing the limiting protrusions, thereby improving production efficiency. On the other hand, since the first limiting protrusion 222 and the second limiting protrusion 223 are relatively small in size, they can still provide a reliable limiting function. Therefore, the formation of the limiting protrusions by bending a portion of the support slider 22 not only does not reduce the structural strength of the support slider 22, but the resulting special-shaped structure can actually improve the structural strength of the support slider 22 to a certain extent.

[0080] In some embodiments, the limiting fitting 113 can be fixed to the wall surface of the sliding fitting portion 11 by welding, bonding, etc., which not only plays a limiting role but also can improve the structural strength of the sliding fitting portion 11; in other embodiments, such as Figure 5 As shown, the limiting fitting 113 can be formed integrally with the sliding fitting portion 11 , does not require assembly, is easy to process and form, and has a simpler structure and a more secure connection.

[0081] In some specific embodiments, Figure 5 As shown, a portion of the sidewall of the sliding fitting portion 11 can be separated from the rest of the portion and then bent outward (i.e., in a direction away from the accommodating cavity 101), thereby defining a position-limiting fitting 113. In other words, the position-limiting fitting 113 is integrally formed with the sliding fitting portion 11. On the one hand, no additional components are required to form the position-limiting fitting 113, which reduces the number of components and the amount of raw materials used, thereby reducing production costs and eliminating the assembly process of installing and fixing the position-limiting fitting 113, thereby improving production efficiency. On the other hand, since the position-limiting fitting 113 can perform a reliable position-limiting function despite its small size, the fact that it is formed by bending a portion of the sliding fitting portion 11 does not reduce the structural strength of the sliding fitting portion 11. On the contrary, the resulting special-shaped structure can improve the structural strength of the sliding fitting portion 11 to a certain extent.

[0082] In some embodiments of the present invention, Figure 5 、 Figure 24 As shown, the side wall of the sliding groove 221 extending into the hooking groove 112 can be provided with a flange 224, which is bent downward. The flange 224 can enhance the structural strength of the side wall of the sliding groove 221, so that when the sliding fitting portion 11 extends into the sliding groove 221 and moves along the sliding groove 221, the side wall of the sliding groove 221 is not easily deformed, thereby affecting the smoothness of the drawer body 10. Moreover, the drawer body 10 and its contents, which are heavier, can be supported.

[0083] In some embodiments of the present invention, the flange 224 and the side wall of the sliding groove 221 can be smoothly connected, and the smooth transition connection can be against the bottom wall of the hook groove 112. During the sliding of the sliding fitting part 11 along the sliding groove 221, the smooth transition connection can be slidably fitted with the bottom wall of the hook groove 112, and the friction resistance is small, so that the drawer body 10 can be pulled out more smoothly.

[0084] In some embodiments, as Figure 20-24 As shown, the support sliding member 22 can be a metal member, and the support sliding member 22 can be integrally formed to form a sheet metal support structure. The support sliding member 22 is easy to process and form, has high structural strength, and does not require the installation of limiting protrusions, flanges 224, etc., thereby improving production efficiency and structural reliability.

[0085] In some embodiments, as Figure 7 and Figure 18-19 As shown, the support slider 22 can be secured to the bottom housing 21 via a first fixing connector 41. This connection is simple, reliable, easy to assemble and disassemble, and is not limited by component material. Specifically, a third fixing hole 226 can be defined on the sidewall of the support slider 22 facing away from the accommodating cavity 101, and a fourth fixing hole 211 can be defined on the sidewall of the bottom housing 21 on the corresponding side. The first fixing connector 41 is inserted through the third fixing hole 226 and the fourth fixing hole 211 to connect the support slider 22 to the bottom housing 21.

[0086] In some embodiments, as Figure 20 As shown, there can be multiple third fixing holes 226, and the multiple third fixing holes 226 can be located on the sides away from each other of the first limiting protrusion 222 and the second limiting protrusion 223, so as to prevent the first fixing connector 41 from interfering with the limiting fitting 113 and affecting the sliding of the sliding fitting portion 11, and to facilitate more reliable fixation of the supporting sliding member 22. In some embodiments, the first fixing connector 41 can be a screw or bolt.

[0087] In an embodiment of the present invention, the connection between the support sliding member 22 and the bottom shell 21 includes, but is not limited to, connection via the first fixed connector 41, which only needs to meet the requirement of reliable connection between the two. In some embodiments, the support sliding member 22 and the bottom shell 21 can also be connected by clamping, welding, bonding, etc.

[0088] In some embodiments of the present invention, Figure 12-17 As shown, the outer wall of the drawer body 10 may be provided with a protrusion 12, and the protrusion 12 may be located below the sliding fitting portion 11. When the drawer body 10 is in engagement with the drawer bottom shell assembly 20, as shown in FIG. Figure 12 and Figure 13As shown, the protrusion 12 can be located below the supporting slide 22. When the drawer body 10 moves upward a certain distance, the protrusion 12 can abut against the supporting slide 22 to limit the upward displacement of the drawer body 10 and prevent the sliding fitting part 11 from falling out of the sliding groove 221, thereby preventing the drawer body 10 from falling off upward.

[0089] In such Figure 12 In the example shown, there may be multiple protrusions 12 distributed along the pulling direction, thereby ensuring that the drawer body 10 can be limited by the protrusions 12 when pulled out to any size to prevent the drawer body 10 from falling off.

[0090] In some embodiments of the present invention, Figure 15 As shown, the raised portion 12 and the drawer body 10 can be independently machined and molded. In other words, the raised portion 12 and the drawer body 10 are separate components that are connected together, for example, they can be fixedly connected or detachably connected. By designing them as independently machined and molded components, the raised portion 12 and the drawer body 10 can be made of any material, for example, the raised portion 12 can be made of plastic, and the drawer body 10 can be made of plastic or sheet metal. Furthermore, the raised portion 12 can be easily machined into any desired structure, making it easy to mold and demold, and facilitating assembly of the drawer body 10 and the drawer bottom shell assembly 20.

[0091] In some specific embodiments, Figure 13 As shown, the top surface of the protrusion 12 can be flat, which effectively prevents the drawer body 10 from falling off and facilitates pre-installation positioning. The side surface of the protrusion 12 facing the accommodating cavity 101 can be flat, so that the protrusion 12 can be in contact with the outer wall of the drawer body 10, making the installation of the protrusion 12 more stable and facilitating pre-installation positioning of the protrusion 12.

[0092] In some implementations, such as Figure 14-17 As shown, the protrusion 12 can be fixed to the drawer body 10 by the second fixing connector 42. The connection method is simple and firm. The protrusion 12 is not easy to fall off, and the protrusion 12 is easy to disassemble and replace.

[0093] In some specific embodiments, Figure 14-17 As shown, a first fixing hole 111 may be provided on the side wall of the drawer body 10, and a second fixing hole 122 may be provided on the raised portion 12. The second fixing connector 42 may pass through the first fixing hole 111 and the second fixing hole 122 to cooperate. The connection structure is simple and reliable, and the connection method is not limited by the material of the components. After the connection is completed, the head of the second fixing connector 42 may be against the side wall of the drawer body 10 and located in the accommodating cavity 101 to make the cavity wall of the accommodating cavity 101 complete. In some embodiments, the second fixing connector 42 may be a screw or a bolt, etc.

[0094] It should be noted that the connection method of the drawer body 10 and the raised portion 12 includes but is not limited to being connected by the second fixed connector 42, which only needs to meet the requirement of reliable connection between the two. In some embodiments, the drawer body 10 and the raised portion 12 can also be connected by clamping, welding, bonding, etc.

[0095] In some embodiments of the present invention, the side wall of the drawer body 10 and the raised portion 12 can be plugged together. Figure 13 and Figure 16 As shown, the side wall of the drawer body 10 may be provided with an inserting groove 103 , and a portion of the protrusion 12 may be inserted into the inserting groove 103 to achieve the connection between the protrusion 12 and the drawer body 10 .

[0096] In some embodiments, the plug-in slot 103 may have a top opening, and a portion of the protrusion 12 may be inserted into the plug-in slot 103 through the top opening, so that the slot wall of the plug-in slot 103 can support the protrusion 12, and the protrusion 12 is not easy to fall out of the plug-in slot 103, and can reliably cooperate with the supporting sliding member 22.

[0097] In some embodiments, the protrusion 12 is plugged into the drawer body 10 and connected through the second fixed connector 42, which has higher connection reliability. In addition, the plug-in structure can play a pre-positioning role, making the second fixed connector 42 easier to install.

[0098] In some embodiments, as Figure 17 As shown, the bottom wall of the raised portion 12 can be provided with two insertion portions 121, spaced apart. When the raised portion 12 is installed, one insertion portion 121 can be inserted into the insertion slot 103, while the other insertion portion 121 can be positioned outside the insertion slot 103. The two insertion portions 121 provide position control on both sides of the slot wall of the insertion slot 103, making the installation of the raised portion 12 more stable. Furthermore, since both insertion portions can be inserted into the insertion slot 103, the installation of the raised portion 12 is more flexible, which helps improve installation efficiency.

[0099] In the embodiment of the present invention, the specific structure of the protrusion 12 can be flexibly set according to actual conditions. Figure 16 As shown, in some embodiments, a portion of the side wall of the drawer body 10 can be separated from the rest of the side wall of the drawer body 10 and then bent outward to define a plug-in slot 103, which is similar to a Venetian blind structure. The structure is simple and does not require additional components to form the plug-in slot 103. The assembly process of the components is eliminated, thereby reducing production costs and improving production efficiency.

[0100] In some specific embodiments, Figure 16As shown, both ends of the bent extension portion of the side wall of the drawer body 10 can be connected to the rest of the side wall of the drawer body 10, so that both ends of the insertion groove 103 along the pulling direction are closed to prevent the protrusion 12 from falling out of the insertion groove 103 during the pulling process of the drawer body 10.

[0101] In some embodiments of the present invention, Figure 13 As shown, the protrusion 12 and the supporting sliding member 22 can be spaced apart so that the drawer body 10 can move a certain distance in the up and down directions, thereby facilitating the disassembly and assembly of the drawer body 10 and the drawer bottom shell assembly 20 .

[0102] Specifically, if Figure 9 and Figure 10 As described above, after the drawer body 10 and the drawer bottom shell assembly 20 are assembled, the limiting fitting 113 is located at the rear side of the first limiting protrusion 222 and at the front side of the second limiting protrusion 223. During the process of pulling out the drawer body 10, the limiting fitting 113 moves between the first limiting protrusion 222 and the second limiting protrusion 223. When the drawer body 10 needs to be disassembled, the drawer body 10 can be pulled out until the limiting fitting 113 and the rear surface of the first limiting protrusion 222 are in clearance, and then the drawer body 10 can be slightly lifted up to a certain height so that the limiting fitting 113 and the first limiting protrusion 222 are staggered in the vertical direction, so that the limiting fitting 113 can pass over the first limiting protrusion 222 and be disassembled as shown in FIG. Figure 13 As shown, the drawer body 10 moves to the front side of the first limiting protrusion 222. At this time, the drawer body 10 can be further pulled outward until the sliding engagement portion 11 is released from the sliding groove 221 and the supporting sliding member 22 is released from the hooking groove 112, thereby completing the separation of the drawer body 10 and the drawer bottom shell assembly 20. The distance between the protrusion 12 and the supporting sliding member 22 defines the maximum height of the drawer body 10 when it is gently lifted upward.

[0103] In some embodiments, the raised portion 12 may be a plastic part. Plastic parts are easy to process and shape, and can meet the requirements of the special-shaped structure of the raised portion 12, reducing the difficulty of the processing process. Plastic parts have strong hardness, and can cooperate with the side walls of the drawer body 10 to obtain a more stable structure. Plastic parts are also light and low in cost, making the drawer body 10 easy to draw and pull, and the drawer assembly 100 has a low production cost.

[0104] The following describes a drawer assembly 100 according to a specific embodiment of the present invention with reference to the accompanying drawings. It should be understood that the following description is merely illustrative and should not be construed as limiting the invention.

[0105] like Figures 1-8 As shown, the drawer assembly 100 may include a drawer body 10 and a drawer bottom shell assembly 20 .

[0106] like Figure 14-17As shown, the left and right walls of the drawer body 10 are respectively provided with a sliding engagement portion 11 and an insertion groove 103. The sliding engagement portion 11 has a hooking groove 112 extending in the front-to-back direction, allowing the drawer body 10 to be pulled in the front-to-back direction. The raised portion 12 is located on the outer side of the side wall of the drawer body 10 and partially inserted into the insertion groove 103.

[0107] like Figures 18-24 As shown, the drawer bottom housing assembly 20 may include a bottom housing 21 and two support slides 22. The two support slides 22 may be respectively engaged with the left and right inner side walls of the bottom housing 21. The support slides 22 define a sliding groove 221. The side wall of the sliding groove 221 adjacent to the accommodating cavity 101 is provided with a flange 224, and the bottom wall is provided with a first limiting protrusion 222 and a second limiting protrusion 223.

[0108] like Figures 1-13 As shown, a portion of the sliding fitting portion 11 on both sides of the drawer body 10 can be respectively extended into the corresponding sliding groove 221, and a portion of the supporting sliding member 22 can be extended into the corresponding hooking groove 112. The protrusion 12 is located below the supporting sliding member 22.

[0109] Among them, such as Figures 9-12 As shown, the sliding groove 221 can guide the sliding fitting part 11 in the front-to-back direction to realize the pulling and pulling of the drawer body 10; the first limiting protrusion 222 and the second limiting protrusion 223 limit the sliding fitting part 11 in the front-to-back direction to limit the pulling and pulling travel range of the drawer body 10; the protrusion 12 and the supporting sliding member 22 can limit the sliding fitting part 11 in the up and down directions, and the two side walls of the sliding groove 221 can limit the sliding fitting part 11 in the left and right directions to prevent the sliding fitting part 11 from falling out of the sliding groove 221.

[0110] The raised portion 12 is formed as a plastic limiter, the sliding fitting portion 11 is formed as a drawer flange, and the supporting sliding member 22 is formed as a sheet metal support member, forming a sliding structure to realize the slide rail function. The sliding function is realized by utilizing the characteristics of the sheet metal and plastic itself, replacing the ball bearing slide rail structure in the related technology, thereby reducing costs and subsequent maintenance costs.
