Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and in particular to a drawer assembly and cabinet body that prevents the drawer from falling off. Background Technology

[0002] Furniture such as cabinets usually need to be equipped with drawers to hold items. The traditional wooden drawer slides in the existing technology use milled wide grooves in the board to achieve sliding, without a locking structure design. When the user pulls out the drawer beyond the preset travel or is overloaded, the drawer is prone to completely falling out, which poses a safety hazard of drawer slippage and injury.

[0003] Some drawer components have been improved; see [link / reference]. Figure 1 As shown, Figure 1 This is a structural diagram of an existing anti-slip drawer. Building upon the traditional sliding structure of milled, wide grooves in wooden drawer slides, a limiting block is added to the top panel of the cabinet. When drawer 100 is pulled out to the end of its travel, its rear end plate rigidly interferes with the limiting block 300, mechanically locking drawer 100 to prevent it from slipping out.

[0004] The applicant has discovered that the existing drawer anti-fall-off structures have at least the following technical problems:

[0005] 1. Visually exposed defects: In order to achieve the maximum drawer pull-out stroke, the limit block must be fixed to the front end of the top panel of the cabinet. This results in the limit block being exposed in the gap between the drawer and the cabinet when the drawer is closed, which damages the visual integrity of the cabinet.

[0006] 2. Installation location limitations: The installation height of the limit block must match the back panel of the drawer, which forces the existence of a top panel / shelf structure on the top of the drawer, resulting in design location limitations.

[0007] 3. Difficult installation in confined spaces: The step-by-step installation logic of "installing the drawer first and then the limiting block" requires the operator to complete the three-dimensional positioning of the limiting block and the screw tightening within the confined space of the drawer, making the assembly difficult. Utility Model Content

[0008] The purpose of this utility model is to provide an anti-fall-off drawer assembly and cabinet to solve the technical problems of limited installation location and difficult installation of the anti-fall-off structure of drawers in the prior art; the various technical effects of the preferred technical solution among the many technical solutions provided by this utility model are described in detail below.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] The anti-fall-off drawer assembly provided by this utility model includes a drawer body, a guide rail, and a slide groove, wherein:

[0011] Of the guide rail and the slide rail, one is provided on the side wall of the drawer body, and the other is provided on the side panel of the cabinet. The guide rail and the slide rail are slidably connected.

[0012] The chute includes a chute body and a constricted groove that are connected to each other. The width of the constricted groove is smaller than the width of the chute body, thereby forming a limiting step at the connection between the two.

[0013] When the drawer is pulled out to its limit position, the drawer tilts downward under the action of gravity, and the limiting step abuts against the guide rail, thereby restricting the drawer from being pulled out further; when the drawer is lifted up under the support of external force and is in a horizontal state, the guide rail can disengage from the groove at the constriction groove.

[0014] Preferably, the side of the constriction groove facing away from the slide body is the open side, and the side of the slide body facing away from the constriction groove is the closed side.

[0015] Preferably, the guide rail protrudes from the side panel of the cabinet, and the guide rail includes a guide strip and a locking block, wherein:

[0016] The locking block is fixed to one end of the guide strip, and the width of the locking block is greater than the width of the guide strip. When the drawer is pulled out to its limit position, the drawer tilts downward under the action of gravity, and the limiting step abuts against the locking block.

[0017] The width of the locking block is not greater than the width of the constriction groove. When the drawer is in a horizontal state under external force, the locking block can disengage from the slide groove at the constriction groove.

[0018] Preferably, the width of the slide body is greater than the width of the guide rail, and the drawer can undergo relative displacement in the vertical direction between itself and the guide rail under external force.

[0019] Preferably, the guide strip is a straight strip structure.

[0020] Preferably, the guide rail is an integrally molded structure, and the guide rail is located on opposite sides of the cabinet.

[0021] Preferably, the slide groove further includes a flared groove, which is connected to one end of the constricted groove away from the slide groove body, and the width of the flared groove gradually increases in the direction away from the constricted groove.

[0022] Preferably, the grooves are formed on opposite sides of the drawer.

[0023] Preferably, the guide rail is horizontally arranged; when the drawer is in a horizontal state, the slide is horizontally arranged.

[0024] This utility model also provides a cabinet body, including a cabinet side panel and the aforementioned anti-fall-off drawer assembly.

[0025] The anti-fall-off drawer assembly and cabinet provided by this utility model have the following advantages compared with the prior art: A limiting step is formed at the connection between the slide rail body and the constricted groove. When the drawer is pulled out to its limit, it tilts downwards under gravity. At this time, the limiting step abuts against the guide rail, preventing the drawer from being pulled out further. When the drawer needs to be disassembled, external force supports the drawer, keeping it horizontal, allowing the guide rail to disengage from the constricted groove and the drawer to be disassembled. The above-mentioned anti-fall-off drawer assembly facilitates drawer assembly and disassembly, and has a simple structure and is easy to use. Attached Figure Description

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0038] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] This utility model provides a drawer assembly and cabinet body that prevents the drawer from falling off. When the drawer is pulled out to its limit position, it tilts downward under the action of gravity. At this time, the limiting step abuts against the guide rail, which can limit the drawer from being pulled out further. When the drawer needs to be disassembled, external force supports the drawer, making the drawer horizontal. The guide rail can disengage from the groove at the constriction groove, and the drawer can be disassembled.

[0040] The following is combined Figures 2-8 The technical solution provided by this utility model will be described in more detail.

[0041] Example 1:

[0042] like Figures 2-8 As shown, the anti-fall-off drawer assembly provided by this utility model includes a drawer body 100, a guide rail 1, and a slide 2. One of the guide rail 1 and the slide 2 is disposed on the side wall of the drawer body 100, and the other is disposed on the cabinet side panel 200. The guide rail 1 and the slide 2 are slidably connected. In this embodiment, the slide 2 is disposed on the drawer, and the guide rail 1 is disposed on the cabinet side panel 200. The slide 2 includes a connected slide body 21 and a narrow groove 22. The width of the narrow groove 22 is smaller than the width of the slide body 21, thus forming a limiting step 211 at the connection point. When the drawer is pulled out to its limit position, the drawer tilts downwards under gravity, and the limiting step 211 abuts against the guide rail 1, thereby restricting the drawer from being pulled out further. When the drawer is lifted under external force and is in a horizontal state, the guide rail 1 can disengage from the slide 2 at the narrow groove 22.

[0043] See Figures 2-4 As shown, the narrow groove 22 refers to the narrow-width groove segment connected to the slide body 21. Specifically, it can be formed by changing the spacing between the side walls of the slide 2, and a limiting step 211 is formed at the narrowed part of its width, as shown in the figure. Figure 4 and Figure 5 As shown. The limiting step 211 refers to the abrupt change in width at the connection between the slide body 21 and the constriction groove 22, specifically manifested as an inwardly protruding blocking surface on the side wall of the slide 2. See [reference needed]. Figure 4 and Figure 5 As shown, when the drawer is pulled out to its limit position, the limiting step 211 abuts against the guide rail 1, preventing the drawer from being pulled out further.

[0044] Specifically, when a drawer is fully extended, its center of gravity shifts forward, causing the pulled end of the drawer to droop naturally, such as... Figure 5 As shown, the slide 2 tilts with the drawer, causing the limiting step 211 to contact the guide rail 1. At this time, the guide rail 1 is confined within the constriction groove 22 and cannot slide further, forming a physical lock. When it is necessary to disassemble the drawer, see [reference needed]. Figure 8 As shown, applying external force to lift the drawer and restore it to a horizontal state, after the guide rail 1 aligns with the constriction groove 22, it can slide along the constriction groove 22. This process can be completed by lifting the drawer and keeping it horizontal, avoiding the difficulty of tightening screws in a confined space.

[0045] Through the above technical solution, this application achieves anti-detachment function by utilizing a gravity-triggered self-locking mechanism while maintaining the normal sliding function of the drawer, thus avoiding the exposed limiting structure from disrupting the visual integrity of the cabinet. The slide groove 2 structure can adapt to different cabinet side panel 200 positions, breaking through the dependence of traditional limiting blocks on the top panel structure. The cooperation between the guide rail 1 and the slide groove 2 simplifies the drawer installation and disassembly process to an angle adjustment action, effectively improving assembly efficiency and reducing operational difficulty.

[0046] As an optional implementation, see Figure 4 and Figure 5 As shown, the side of the constriction groove 22 that is away from the slide body 21 is the open side, and the side of the slide body 21 that is away from the constriction groove 22 is the closed side.

[0047] The open side refers to the open groove structure formed at the end of the slide 2. Specifically, it can be achieved by milling sheet metal to form a through-channel, which is used to guide the guide rail 1 to disengage from the slide 2 in a specific direction. The closed side refers to the non-through groove structure set at the beginning of the slide 2.

[0048] As an optional implementation, see Figures 3-8 As shown, the guide rail 1 protrudes from the cabinet side panel 200. The guide rail 1 includes a guide bar 11 and a locking block 12. The locking block 12 is fixed to one end of the guide bar 11, and the width of the locking block 12 is greater than the width of the guide bar 11. When the drawer is pulled out to its limit position, the drawer tilts downward under the action of gravity, and the limiting step 211 abuts against the locking block 12. The width of the locking block 12 is not greater than the width of the constriction groove 22. When the drawer is in a horizontal state under the support of external force, the locking block 12 can disengage from the slide groove 2 at the constriction groove 22.

[0049] See Figure 6 As shown, when the drawer is closed, the latch 12 is located in the slide groove 2 near the closed side. (See Figure 12) Figure 7 As shown, when the drawer is pulled to its limit position, the locking block 12 abuts against the limiting step 211, preventing the drawer from being pulled out further. See [reference needed]. Figure 8 As shown, when it is necessary to disassemble the drawer, lift the drawer up and keep it horizontal. The locking block 12 can slide out of the groove 2 from the constricted opening to separate the drawer from the cabinet.

[0050] As an optional implementation, see Figure 8 As shown, the width of the slide body 21 is greater than the width of the guide rail 1, and the drawer can undergo relative displacement in the vertical direction between itself and the guide rail 1 under the support of external force.

[0051] The above structure, see Figure 8 As shown, when it is necessary to disassemble the drawer, lift the drawer up and keep it horizontal. Since the width of the slide body 21 is greater than the width of the guide rail 1, the locking block 12 can slide out of the slide 2 from the constricted part, realizing the separation of the drawer from the cabinet.

[0052] As an optional implementation, see Figure 3As shown, the guide bar 11 is a straight strip structure. A straight strip structure refers to a strip-shaped component with a continuous, straight extension. During assembly, the guide bar 11 is aligned with the slide groove 2 along the straight direction, and matching can be achieved by adjusting the alignment accuracy of a single axis. During the sliding of the drawer, the contact surface between the guide bar 11 and the slide groove 2 forms a continuous linear support, so that the friction load is evenly distributed along the length direction, avoiding local stress concentration.

[0053] As an optional implementation, the guide rail 1 is a one-piece molded structure, located on opposite sides of the cabinet. During processing, the guide rail 1 is formed into a continuous and uninterrupted integral structure through a one-piece molding process, eliminating the gaps at the joints of traditional split guide rails, thereby avoiding the problem of jamming caused by local deformation of the guide rail during drawer sliding.

[0054] When the above structure is applied to a cabinet, the guide rail 1 is usually a one-piece cut wooden structure.

[0055] As an optional implementation, see Figure 4 , Figure 5 As shown, the slide 2 also includes a flared groove 23, which is connected to the end of the constricted groove 22 away from the slide body 21. The width of the flared groove 23 gradually increases in the direction away from the constricted groove 22.

[0056] The flared groove 23 features a gradually expanding design, forming a guide slope from the open end to the narrowed end. This slope provides lateral guidance when the guide rail 1 is inserted into the slide groove 2. The sidewalls of the flared groove 23 gradually constrain the guide rail 1 to a position matching the width of the narrowed groove 22, ultimately allowing it to slide accurately into the narrowed groove 22. During this process, the gradual width variation of the flared groove 23 allows for a certain degree of lateral offset in the initial insertion stage. This gradual guidance eliminates positional deviations and reduces the initial alignment accuracy requirements between the guide rail 1 and the narrowed groove 22 during assembly.

[0057] As an optional implementation, see Figure 2 and Figure 3 As shown, the slide groove 2 is formed on the opposite sides of the drawer, which improves the stability of the sliding structure between the drawer and the cabinet.

[0058] As an optional implementation, see Figure 2 and Figure 3 As shown, the guide rail 1 is horizontally positioned; when the drawer is in a horizontal position, the slide 2 is also horizontally positioned. The horizontal positioning of the guide rail 1 ensures that the drawer maintains a linear motion reference when sliding in a single direction, facilitating the pulling, closing, or disassembly of the drawer.

[0059] In this embodiment, the anti-fall-off drawer assembly is installed by fixing the guide rail 1 to the cabinet side panel 200. When the drawer needs to be pulled out, it is pulled outwards, and the drawer tilts downwards due to its own weight, completing the mechanical self-locking. To remove it, the drawer is pulled outwards to its travel limit position. See [link to documentation]. Figure 4 and Figure 5 As shown, after the drawer's limiting step 211 collides with the locking block 12 and generates feedback, the drawer box needs to be lifted vertically so that the locking block 12 is located in the constriction groove 22 before it can be separated.

[0060] Example 2:

[0061] This embodiment provides a cabinet, including a cabinet side panel 200 and the aforementioned anti-fall-off drawer assembly.

[0062] The cabinet in this embodiment can be a wooden cabinet.

[0063] The cabinet in this embodiment uses the aforementioned anti-fall-off drawer assembly. The locking block 12 and the narrow groove 22 are vertically offset, and the locking block 12 abuts against the limiting step 211, locking the drawer when it is pulled to its limit position. This completely hides the traditional exposed limiting block, achieving a clean appearance with no visible parts. It offers high installation flexibility, breaking through the fixed installation position limitations of the original solution, and can be installed in any location within the cabinet that meets space requirements. Operation is simple and efficient; the drawer automatically locks itself after being pushed in, eliminating the need for precise alignment and disassembly. Simply pull the drawer out to the limiting point and lift it lightly to separate it.
