Description

Technical Field

[0001] This utility model relates to the field of furniture technology, specifically to a slide rail structure and a pull-out basket. Background Technology

[0002] In furniture, drawer slides have become an indispensable core component due to their convenience. However, traditional drawer slide designs have significant technical bottlenecks: when the drawer slides are folded up, if the furniture tilts due to unexpected factors, the drawer slides can easily slide relative to the weight of the storage components they are connected to, causing the drawer slides to extend on their own, affecting the safety and structural stability of the furniture. Utility Model Content

[0003] This utility model provides a sliding rail structure to solve the problem in the prior art where, when furniture with a sliding rail structure tilts due to unexpected factors, the sliding rail structure in the folded state easily slides relative to the storage components it is connected to and extends on its own under the influence of gravity.

[0004] To achieve the above objectives, the present invention adopts the following technical solutions:

[0005] A slide rail structure includes a first slide rail assembly and a second slide rail assembly that are interlocked and can slide relative to each other. The first slide rail assembly is used to be fixedly installed on a mounting carrier, and the second slide rail assembly is used to be fixedly installed on both sides of a storage component.

[0006] The first slide rail assembly includes a first rail body and a first roller disposed within the first rail body. The first roller is disposed near one end of the first rail body and abuts against the second rail body. A baffle is disposed on the first rail body at the end away from the first roller, and the baffle is used to limit the sliding stroke of the second slide rail assembly relative to the first slide rail assembly.

[0007] The second slide rail assembly includes a second rail body and a second roller disposed within the second rail body;

[0008] A limiting member is also provided at the end of the first rail body away from the first roller. When the slide rail structure is tilted in the retracted state, the limiting member can prevent the second roller from rolling past the limiting member.

[0009] Furthermore, the first track body includes a first top plate, a first side plate, and a bottom plate that are fixedly connected. The first top plate, the first side plate, and the bottom plate form a shape that is open on one side, that is, the first track body has a cross-section of a shape.

[0010] The second track body includes a second top plate and a second side plate that are fixedly connected, and the second top plate and the second side plate form an L-shape.

[0011] With the first slide rail assembly and the second slide rail assembly engaged, the first roller abuts against the lower surface of the second top plate, and the second roller abuts against the upper surface of the bottom plate.

[0012] The limiting component is set on the base plate.

[0013] Furthermore, the limiting member is arched in shape, arching towards the interior of the first rail body;

[0014] The distance from the lower edge of the second roller to the upper surface of the second top plate is less than the distance from the top of the limiting member to the lower surface of the first top plate.

[0015] Furthermore, the limiting member is wedge-shaped and protrudes towards the interior of the first rail body, with the inclined side of the limiting member away from the baffle.

[0016] The distance from the lower edge of the second roller to the upper surface of the second top plate should be less than the distance from the top of the limiting member to the lower surface of the first top plate.

[0017] Furthermore, the limiting member is an elastic member, which can extend and retract in a direction perpendicular to the base plate;

[0018] Without being affected by external forces, the distance from the lower edge of the second roller to the upper surface of the second top plate is greater than the distance from the top of the limiting member to the lower surface of the first top plate.

[0019] The distance from the lower edge of the second roller to the upper surface of the second top plate should be less than the distance from the lower surface of the first top plate to the upper surface of the bottom plate.

[0020] A pull-out basket includes a basket frame, a basket net, and a handle. The basket net is laid on the basket frame for carrying and storing items. A set of the aforementioned slide rail structures are mirror-symmetrically arranged on both sides of the basket frame. A first slide rail assembly is used to be fixedly installed on the mounting carrier, and a second slide rail assembly is fixedly connected to both sides of the basket frame. The handle is located at the front end of the pull-out basket in the opening direction.

[0021] The beneficial effects of this utility model are as follows:

[0022] The slide rail mechanism provided in this utility model introduces a limiting member, so that when the slide rail structure is tilted in the stored state, the limiting member can prevent the second roller from rolling past the limiting member. However, when the slide rail mechanism is manually pulled out, the second roller can be driven to roll past the limiting member, thereby achieving the "soft locking" effect of the slide rail mechanism.

[0037] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0038] like Figure 1-12 As shown in the figure, this utility model embodiment provides a slide rail structure and a drawer basket, wherein the slide rail structure is as follows: Figure 3-12As shown, the slide rail structure includes a first slide rail assembly 1 and a second slide rail assembly 2 that are interlocked and can slide relative to each other. The first slide rail assembly 1 is used to be fixedly installed on the mounting carrier such as a cabinet or bracket, and the second slide rail assembly 2 is used to be fixedly installed on both sides of storage components such as drawers or pull baskets, so that the storage component can be pulled out and installed on the mounting carrier.

[0039] The first slide rail assembly 1 includes a first rail body 11 and a first roller 12 disposed within the first rail body 11. The first roller 12 is disposed near one end of the first rail body 11, and a baffle 112 is disposed on the end of the first rail body 11 away from the first roller 12; specifically as follows: Figure 7 and Figure 12 As shown, both the baffle 112 and the first roller 12 limit the sliding stroke of the second slide rail assembly 2 relative to the first slide rail assembly 1, and the combination of the baffle 112 and the first roller 12 prevents the first slide rail assembly 1 and the second slide rail assembly 2 from separating during relative sliding. The first rail body 11 includes a first top plate 1101, a first side plate 1102 and a bottom plate 1103 fixedly connected. The first top plate 1101, the first side plate 1102 and the bottom plate 1103 form a single-sided open [ shape, that is, the first rail body 11 has a [ shaped cross section;

[0040] The second slide rail assembly includes a second rail body 21 and a second roller 22 disposed within the second rail body 21. The second rail body 21 includes a second top plate 2101 and a second side plate 2102 fixedly connected. The second top plate 2101 and the second side plate 2102 form an L-shape, that is, the second rail body 21 has an L-shaped cross-section.

[0041] When the first slide rail assembly 1 and the second slide rail assembly 2 are engaged with each other, the first roller 12 abuts against the lower surface of the second top plate 2101, and the second roller 22 abuts against the upper surface of the bottom plate 1103, so that the second slide rail assembly 2 is supported by the first slide rail assembly 1 and can slide relative to the first slide rail assembly 1.

[0042] As a major improvement of this utility model, such as Figure 7As shown, a limiting member 111 is also provided at the end of the first rail body 11 away from the first roller 12. The limiting member 111 is specifically provided on the base plate 1103. During the storage process of the slide rail structure, the second roller 21 rolls past the limiting member 111 and reaches the position of the baffle 112, so that the slide rail structure is in the storage state. When the slide rail assembly is in the storage state and the slide rail structure tilts, the limiting member 111 can prevent the second roller 22 from rolling past the limiting member 111. That is, the limiting member 111 is used to lock the position of the second roller 22 (the blocking effect means that when pushing or pulling the second slide rail assembly 2 so that the second roller 22 passes past the limiting member 111 from both sides, the user needs to exert force, that is, the "blocking" under the condition of no external force interference, thereby realizing the "soft locking" of the slide rail structure in the storage state).

[0043] Specifically, in one embodiment, the limiting member 111 is an arch shape that arches towards the inside of the first rail body 11, so that the limiting member can also prevent the second roller 22 from rolling over the limiting member 111, while reducing the wear of the second roller 22 and the limiting member 111 when the second roller 22 passes over the limiting member 111; obviously, under this working principle, the distance d1 from the lower edge of the second roller 22 to the upper surface of the second top plate 2101 is less than the distance d2 from the top of the limiting member 111 to the lower surface of the first top plate 1101.

[0044] In another specific embodiment, such as Figure 8 As shown, the limiting member 111 is wedge-shaped, protruding towards the interior of the first rail body 11 (i.e., the two sides of the limiting member 111 are inclined and vertical surfaces, respectively). The inclined side of the limiting member 111 is away from the baffle 112. Obviously, during the slide rail structure's retraction process, the second roller 22 can roll directly over the limiting member 111 via its inclined surface. However, when the slide rail assembly is tilted in the retracted state, the second roller 22 is blocked by the vertical surface of the wedge-shaped limiting member 111. However, it cannot slide past the limit member 111. When pulling out the second slide rail assembly 2, the user needs to press down the end of the second rail body 21 away from the second roller 22 and use the lever principle to lift the second roller 22 so that the second roller 22 can pass past the limit member 111 and the slide rail structure can continue to open. Obviously, under this working principle, the distance d1 from the lower edge of the second roller 22 to the upper surface of the second top plate 2101 is less than the distance d2 from the top of the limit member 111 to the lower surface of the first top plate 1101.

[0045] In another embodiment, such as Figure 9As shown, the limiting member 111 is an elastic member (such as a hydraulic spring, mechanical spring, air spring, etc.). The limiting member 111 can extend and retract in a direction perpendicular to the base plate 1103. When the second slide rail assembly 2 is pushed and pulled so that the second roller 22 passes over the limiting member 111 from both sides, due to the obstruction of the limiting member 111, the user needs to exert force to make the second roller 22 abut against the limiting member 111 and compress the limiting member 111 longitudinally so that the second roller 22 can pass over the limiting member 111, thereby realizing the "soft locking" effect of the slide rail structure in the storage state.

[0046] Obviously, under this working principle, when not affected by external forces, the distance d1 from the lower edge of the second roller 22 to the upper surface of the second top plate 2101 is greater than the distance d2 from the top of the limiting member 111 to the lower surface of the first top plate 1101; the distance d1 from the lower edge of the second roller 22 to the upper surface of the second top plate 2101 should be less than the distance d3 from the lower surface of the first top plate 1101 to the upper surface of the bottom plate 1103.

[0047] like Figures 1-2 As shown, the pull-out basket provided by this utility model includes a basket frame 31, a basket net 32, and a handle 33. The basket net 32 ​​is laid on the basket frame 31 and is used to carry and store items. A set of slide rail structures are mirror-symmetrically arranged on both sides of the basket frame 31. The first slide rail assembly 1 is used to be fixedly installed on the mounting carrier, and the second slide rail assembly 2 is fixedly connected to both sides of the basket frame 31. The handle 33 is located at the front end of the pull-out direction of the basket and is used by the user to hold and pull out the basket.

[0048] The slide rail mechanism provided in this utility model introduces a limiting member, so that when the slide rail structure is tilted in the stored state, the limiting member can prevent the second roller from rolling past the limiting member. However, when the slide rail mechanism is manually pulled out, the second roller can be driven to roll past the limiting member, thereby achieving the "soft locking" effect of the slide rail mechanism.

[0049] The embodiments described above merely illustrate the implementation of this utility model, and should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
