Description
Technical Field
[0001] This invention relates to the technical field of assembling and disassembling drawers and sliding rails, and specifically to a quick-release assembly of drawers and sliding rails. Background Technology
[0002] The current assembly of drawers and sliding rails typically involves a connecting post at the front of the sliding rail, a rear hook at the rear, a connecting hole at the bottom of the drawer side panel corresponding to the connecting post, and a slot at the rear of the drawer corresponding to the rear hook. When installing the drawer and sliding rails, the connecting post must be aligned with the connecting hole at the bottom of the drawer, and the rear hook with the slot, making disassembly inconvenient.
[0003] Alternatively, a modular assembly structure can be provided between the drawer and the slide rail to achieve quick disassembly and assembly. See Chinese Invention Patent Publication No. CN121987034A for a quick disassembly and assembly mechanism for a drawer and slide rail, which includes a quick-release component for connecting the slide rail. The quick-release component includes an elastic element and a first connecting member that elastically locks the slide rail. After the first connecting member locks the slide rail, the elastic element deforms under pressure to unlock the slide rail. After the first connecting member separates from the slide rail, the first connecting member is released, causing the elastic element to release its elastic force, and the first connecting member elastically returns to its initial position to lock the slide rail, thus achieving quick disassembly and assembly between the quick-release component and the slide rail. The modular assembly structure is generally relatively large. Summary of the Invention
[0004] This invention proposes a quick-release assembly for drawers and sliding rails, which mainly realizes a quick-release structure between drawers and sliding rails, facilitating the installation and disassembly of drawers and sliding rails.
[0005] A quick-release assembly for drawers and slides designed for this purpose includes a directional assembly structure for connecting the drawer and slides, and also includes an elastic element and a pre-positioning locking structure for connecting the drawer and slides, wherein the elastic element and the directional assembly structure are configured to cooperate with each other. During assembly, the drawer and the moving slide are positioned and connected to the pre-positioning locking structure through the directional assembly structure and trigger the deformation of the elastic element. The elastic element releases its elastic force to drive the drawer to move towards the pre-positioning locking structure until the pre-positioning locking structure locks the drawer and the moving slide. During disassembly, the drawer moves in the direction of unlocking the pre-positioned locking structure under the action of external force, and separates the drawer from the moving slide, so as to achieve quick disassembly and assembly between the drawer and the moving slide.
[0006] The pre-positioning locking structure and the directional assembly structure are arranged at a front-to-back interval at the connection and mating position between the drawer and the moving rail. The pre-positioning locking structure is used to connect the front of the drawer and the moving rail, and the directional assembly structure is used to connect the rear of the drawer and the moving rail, so as to achieve front-to-back fixation between the drawer and the moving rail.
[0007] During assembly, the installation direction of the elastic element that drives the drawer to move is the same as the direction of movement of the moving rail.
[0008] The directional assembly structure includes a positioning part disposed on the rear connector and a positioning block for cooperating with the positioning block; during assembly, the positioning block is inserted into the positioning part.
[0009] The rear connector is provided with a mounting part for fixing the elastic element.
[0010] The rear connector is fixedly installed on the rear of the drawer's side panel, and the positioning block is installed on the rear of the moving rail.
[0011] The side plate is provided with an assembly part for accommodating the moving rail; during assembly, the moving rail is enclosed in the assembly part.
[0012] The pre-positioning locking structure includes a locking groove and a locking tongue; during assembly, the locking tongue is positioned on the locking groove, so that the pre-positioning locking structure provides a pre-positioning connection between the drawer and the moving rail in the unlocked state; when the locking tongue is locked on the inside of the locking groove, it locks the drawer and the moving rail.
[0013] The lock groove is located at the front of the drawer's side panel, and the lock tongue protrudes from the rear of the sliding rail. The latch includes a locking end and a limiting side. During assembly, the side plate is supported on the moving rail, and the locking end of the latch enters the lock groove. When the drawer moves in the locking direction under the action of external force, the limiting side and the inner end face of the lock groove limit the engagement, and the locking end and the upper part of the lock groove lock the position, thereby achieving the locking position and switching the pre-positioning locking structure from the pre-positioning assembly state to the locking state.
[0014] A linear guide is provided between the lock groove and the lock tongue to guide the drawer to move linearly during disassembly and assembly, so that the lock groove and the lock tongue can engage to lock or unlock.
[0015] The beneficial technical effects of the present invention are as follows: 1. The pre-positioning locking structure first pre-positions the drawer and the slide rail during the assembly process, so that the drawer is pre-positioned in an unlocked state.
[0016] 2. The elastic element and the directional assembly structure are set in a corresponding manner. During assembly, after the drawer and the moving rail are positioned and connected through the directional assembly structure and the pre-positioning locking structure, the elastic element is triggered to deform and release the elastic force, driving the drawer to move towards the pre-positioning locking structure until it is locked. The installation is convenient, and under the action of elasticity, the drawer and the moving rail are kept locked, preventing the drawer from falling off the moving rail at will.
[0017] 3. During disassembly, simply apply external force to the drawer to move it in the unlocking direction of the pre-positioned locking mechanism to separate the drawer from the slide rail. The disassembly operation can be completed without the aid of tools, simplifying the disassembly process.
[0018] 4. The drawer and the sliding rail are initially guided and positioned by a directional assembly structure, and then the drawer is automatically moved to the locking position by an elastic element, realizing a quick-installation structure between the drawer and the sliding rail.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. In order to make the above-mentioned objects, features and advantages of this application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0030] See Figures 1-10A quick-release assembly of a drawer and a sliding rail includes a directional assembly structure 3 for connecting a drawer 1 and a sliding rail 2, and also includes an elastic element 4 and a pre-positioning locking structure 5 for connecting the drawer 1 and the sliding rail 2, wherein the elastic element 4 and the directional assembly structure 3 are configured to cooperate with each other. During assembly, drawer 1 and moving rail 2 are positioned and connected to pre-positioning locking structure 5 through directional assembly structure 3 and trigger elastic element 4 to deform. Elastic element 4 releases elastic force to drive drawer 1 to move towards pre-positioning locking structure 5 until pre-positioning locking structure 5 locks drawer 1 and moving rail 2. During disassembly, drawer 1 moves in the unlocking direction of the pre-positioned locking structure 5 under the action of external force, and separates drawer 1 from the moving rail 2, so as to realize quick disassembly and assembly between drawer 1 and moving rail 2.
[0031] The pre-positioning locking structure 5 has a pre-positioning function. During assembly, drawer 1 and moving rail 2 are first pre-positioned by the directional assembly structure 3 and the pre-positioning locking structure 5. At this time, part of drawer 1 is connected to moving rail 2, triggering the deformation of elastic element 4. Elastic element 4 releases its elastic force, driving drawer 1 to move towards the pre-positioning locking structure 5 until it is locked, facilitating installation. During disassembly, only external force needs to be applied to drawer 1 to move it in the unlocking direction to separate drawer 1 from moving rail 2. No tools are required, making the operation simple and quick, and realizing the rapid disassembly and assembly of the screwless fasteners between drawer 1 and moving rail 2.
[0032] The pre-positioning locking structure 5 and the directional assembly structure 3 are arranged at a front-to-back interval at the connection and engagement position between the drawer 1 and the moving rail 2. The pre-positioning locking structure 5 is used to connect the front part of the drawer 1 and the moving rail 2, and the directional assembly structure 3 is used to connect the rear part of the drawer 1 and the moving rail 2, thereby achieving front-to-back fixation between the drawer 1 and the moving rail 2.
[0033] The pre-positioning locking structure 5 and the directional assembly structure 3 are set at a front-to-back interval at the connection and mating position between the drawer 1 and the moving rail 2, forming two connection points at the front and rear of the drawer 1 and the moving rail 2 respectively, realizing the front-to-back connection between the drawer 1 and the moving rail 2.
[0034] During assembly, the installation direction of the elastic element 4 in driving the drawer 1 to move is the same as the movement direction of the moving rail 2.
[0035] During assembly, the installation direction of the elastic element 4 driving the drawer 1 to move is the same as the direction of movement of the moving rail 2, so that when the elastic element 4 releases its elastic force, the drawer 1 slides to the locking position along the extension direction of the moving rail 2. During disassembly, the drawer 1 is pushed along the direction of the moving rail 2, making disassembly and assembly convenient.
[0036] The directional assembly structure 3 includes a positioning part 302 disposed on the rear connector 301 and a positioning block 303 for cooperating with the positioning block 303; during assembly, the positioning block 303 is inserted into the positioning part 302.
[0037] During assembly, the positioning block 303 is inserted into the positioning part 302. Through the interlocking of the positioning part 302 and the positioning block 303, the relative position between the drawer 1 and the moving rail 2 is initially guided and limited, so that the drawer 1 is already on the correct assembly trajectory before the subsequent elastic element 4 drives the movement, thus ensuring the alignment accuracy when the elastic element 4 drives the drawer 1 to move.
[0038] The rear connector 301 is provided with a mounting part 304 for fixing the elastic member 4.
[0039] The mounting part 304 is provided on the rear connector 301, so that the elastic element 4 and the directional assembly structure 3 are integrated on the same component (rear connector 301).
[0040] The rear connector 301 is fixedly installed at the rear of the side panel 101 of the drawer 1, and the positioning block 303 is installed at the rear of the moving rail 2.
[0041] The rear connector 301 is fixedly installed at the rear of the side panel 101 of the drawer 1, the positioning block 303 is installed at the rear of the moving rail 2, and the orientation assembly structure 3 is located at the rear end connection between the drawer 1 and the moving rail 2, so that the rear of the drawer 1 and the rear of the moving rail 2 can achieve positioning and cooperation in the initial assembly stage.
[0042] The side plate 101 is provided with an assembly part 102 for accommodating the moving rail 2; during assembly, the moving rail 2 is covered in the assembly part 102.
[0043] The assembly part 102 is provided on the side plate 101. The moving rail 2 is covered in the assembly part 102 during assembly to prevent the drawer 1 and the moving rail 2 from shifting in the left and right directions during the assembly process.
[0044] The pre-positioning locking structure 5 includes a locking groove 501 and a locking tongue 502. During assembly, the locking tongue 502 is positioned on the locking groove 501, so that the pre-positioning locking structure 5 provides a pre-positioning connection between the drawer 1 and the moving rail 2 in the unlocked state. When the locking tongue 502 is locked on the inside of the locking groove 501, the drawer 1 and the moving rail 2 are locked.
[0045] The pre-positioning locking structure 5 achieves two states through the cooperation of the locking groove 501 and the locking tongue 502. In the unlocked state, the locking tongue 502 is positioned on the locking groove 501, and the drawer 1 and the moving rail 2 are in a pre-positioned connection state. When the locking tongue 502 is locked on the inside of the locking groove 501, the drawer 1 and the moving rail 2 switch to the locked state, realizing the fixed connection between the drawer 1 and the moving rail 2. When disassembling, the locking tongue 502 exits from the inside of the locking groove 501, and the pre-positioning locking structure 5 switches from the locked state back to the unlocked state, which facilitates the disassembly of the drawer 1. The pre-positioning locking structure 5 has a locked state, a pre-positioned state, and an external force unlocking state. It is easy to operate and realizes the quick assembly and disassembly between the drawer 1 and the moving rail 2.
[0046] The locking groove 501 is located at the front of the side panel 101 of the drawer 1, and the locking tongue 502 protrudes from the rear of the moving rail 2. The latch 502 includes a locking end 5021 and a limiting side 5022. During assembly, the side plate 101 is supported on the moving rail 2, and the locking end 5021 of the latch 502 enters the lock groove 501. When the drawer 1 moves in the locking direction under external force, the limiting side 5022 engages with the inner end face of the lock groove 501, and the locking end 5021 locks against the upper part of the lock groove 501, thus achieving a locked position and switching the pre-positioned locking structure 5 from the pre-positioned assembly state to the locked state. The lock groove 501 has a certain length, providing space for relative movement between the drawer and the moving rail, facilitating disassembly and assembly.
[0047] During assembly, the side plate 101 is supported on the moving rail 2, and the locking end 5021 of the locking tongue 502 enters the locking groove 501. At this time, the drawer 1 and the moving rail 2 are in a pre-positioned connection state. When the drawer 1 moves in the locking direction under the action of external force (actually under the action of elasticity), the limiting side 5022 and the inner end face of the locking groove 501 limit the engagement, and the locking end 5021 and the upper part of the locking groove 501 are locked in place. The locking is achieved by the limiting engagement between the limiting side 5022 and the inner end face of the locking groove 501. The locking end 5021 and the upper part of the locking groove 501 are locked in place. The locking end 5021 abuts against the upper end face of the locking groove 501. When the drawer 1 is lifted up, it is blocked by the locking end 5021, so that the drawer 1 cannot be arbitrarily disengaged from the moving rail 2.
[0048] A linear guide 503 is provided between the lock groove 501 and the lock tongue 502 to guide the drawer 1 to move linearly during disassembly and assembly, so that the lock groove 501 and the lock tongue 502 cooperate to lock or unlock.
[0049] The linear guide 503 is disposed between the lock groove 501 and the lock tongue 502, and the drawer 1 moves linearly along the direction defined by the linear guide 503 during the disassembly and assembly process.
[0050] In this embodiment, the rear of the side plate 101 is provided with a plug-in cavity 103, and one end of the rear connector 301 is provided with a plug-in rib 305 for inserting into the plug-in cavity 103. The rear of the side plate 101 is provided with a first fixing hole 104 and a second fixing hole 105 corresponding to the plug-in cavity 103. The rear connector 301 is provided with a first fastening hole 307 corresponding to the first fixing hole 104 and a second fastening hole 306 corresponding to the second fixing hole 105. A first screw is inserted between the first fixing hole 104 and the first fastening hole 307, and a second screw is inserted between the second fastening hole 306 and the second fixing hole 105, so that the rear connector 301 is fixedly connected to the rear of the side plate 101.
[0051] In this embodiment, the moving rail 2 is made of metal profile. The locking tongue 502 and the positioning block 303 are fixed to the moving rail 2 as an inseparable whole. It can be understood that the moving rail 2 is equipped with structures such as the locking tongue 502 and the positioning block 303 through corresponding metal processing technology. The locking tongue 502 and the positioning block 303 are located on the upper part of the moving rail 2.
[0052] In this embodiment, the elastic element 4 includes an installation end 402 that is interference-fitted onto the installation part 304 and an action end 401 that acts on the positioning block 303.
[0053] In this embodiment, the positioning block 303 includes a vertically arranged vertical segment and a horizontally extended horizontal segment. One end of the vertical segment is fixed on the moving rail 2, and the other end of the vertical segment is connected to the horizontal segment. The horizontal segment is used to insert the positioning part 302, and the vertical segment is used to cooperate with the working end 401 of the elastic member 4.
[0054] In this embodiment, the transverse segment is provided with a guide slope end for guiding it into the positioning part 302.
[0055] In this embodiment, drawer 1 is detachably mounted on cabinet 6 via a slide rail assembly. The slide rail assembly includes a fixed rail 7 fixed to the inside of cabinet 6 and a movable rail 2 connected to drawer 1. The fixed rail 7 is fixed to the inside of cabinet 6 with screws.
[0056] In this embodiment, the elastic element 4 is an elastic block (plastic), which can be replaced by a metal elastic element or a spring.
[0057] During installation, the operator first lifts the front end of drawer 1 upwards, so that drawer 1 is tilted with the front higher than the back. Then, drawer 1 is moved towards the moving rail 2, so that the positioning block 303 at the rear of drawer 1 is inserted into the positioning part 302 on the rear connector 301, thus achieving directional assembly connection between the rear of drawer 1 and moving rail 2. At this time, the rear of drawer 1 is inserted and fixed to moving rail 2, but the front of drawer 1 is not yet connected to moving rail 2, and the entire drawer 1 is tilted with the front higher than the back relative to moving rail 2.
[0058] Subsequently, the operator lowers the front end of drawer 1, causing the bottom of the front side panel 101 of drawer 1 to gradually approach and be supported on the moving rail 2. During this downward movement, the locking tongue 502 located at the front of the moving rail 2 enters the locking groove 501 located at the front of the side panel 101 of drawer 1 as the front of drawer 1 descends. The locking end 5021 of the locking tongue 502 enters the locking groove 501, so that the pre-positioning locking structure 5 is in the pre-positioning connection state. When the front end of drawer 1 is fully placed in place, the bottom of the side panel 101 is entirely supported on the moving rail 2.
[0059] After drawer 1 is placed downwards, the elastic element 4 is pressed by the vertical section of the positioning block 303. The elastic element 4 releases its elastic force, driving the entire drawer 1 to move along the extension direction of the moving rail 2 toward the locking direction of the pre-positioning locking structure 5. This causes the limiting side 5022 of the latch 502 to abut against the inner end face of the lock groove 501 for limiting engagement. At the same time, the locking end 5021 of the latch 502 is locked above the inner side of the lock groove 501. The pre-positioning locking structure 5 switches from the pre-positioning assembly state to the locking state.
[0060] During disassembly, the operator only needs to apply a reverse external force to drawer 1, causing drawer 1 to move in the unlocking direction of the pre-positioned locking structure 5. The locking end 5021 of the locking tongue 502 will exit the locking position of the locking groove 501. Then, the front end of drawer 1 will be lifted upward, so that the entire drawer 1 is in an inclined state with the front higher than the back. The positioning block 303 will exit from the positioning part 302, and at the same time, the locking tongue 502 will exit from the locking groove 501, so that drawer 1 can be completely removed from the moving rail 2.
[0061] During assembly, the fixed rail 7 of the slide rail assembly is fixed on the inside of the cabinet 6. When the moving rail 2 slides out of the cabinet 6, it is convenient to install the drawer 1 on the moving rail 2.
[0062] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
