Description

[Technical Field]

[0001] This utility model relates to the field of drawer slide rail connection technology, and in particular to a quick-installation adjustment device for drawer slide rails. [Background Technology]

[0002] Drawer slides are widely used in furniture, cabinets, medical equipment, and other fields. The ease of installation and disassembly directly affects assembly efficiency and maintenance convenience. Traditional slides are typically fixed with screws, requiring repeated adjustments and tightening of multiple screws during installation, which is cumbersome and time-consuming. Especially in situations requiring frequent disassembly and assembly (such as equipment maintenance and modular furniture), traditional fixing methods are inefficient and result in a poor user experience.

[0003] To address this issue, some quick-release structures have emerged in existing technologies, such as elastic latches and push-pull locks. However, these solutions still have the following shortcomings: First, most quick-release structures require the use of both hands or tools, making it impossible to lock / unlock quickly with one hand; second, if there is a lateral deviation between the slide rail and the drawer during installation, the fixed position needs to be readjusted, and fine-tuning is not possible while the drawer is locked; moreover, some latch structures are prone to loosening under vibration or long-term load, leading to slide rail displacement or abnormal noise.

[0004] Furthermore, existing quick-release mechanisms typically rely on complex spring or slider structures, which not only increase manufacturing costs but may also affect service life due to component wear. Therefore, there is an urgent need for a slide rail quick-release device that is easy to operate, has reliable locking, and is adjustable to meet the requirements of efficient installation and long-term stable use. [Utility Model Content]

[0005] The purpose of this utility model is to provide a quick-installation adjustment device for drawer slides, which aims to solve the problems of cumbersome installation and operation of slides and lack of convenient locking function in the prior art.

[0006] This utility model is achieved through the following technical solution:

[0007] A quick-release adjustment device for drawer slides includes a connecting base, on which a lateral adjustment mechanism is provided. The lateral adjustment mechanism is movably connected to a locking device for fixing the slide. The locking device includes a locking base that can cooperate with the lateral adjustment mechanism to generate lateral displacement. A locking member is hinged on the locking base and can be switched to a locked state with the slide by a toggle. An elastic part is provided between the locking base and the locking member to keep them relatively stationary.

[0008] As described above, a quick-release adjustment device for a drawer slide rail includes a limiting groove on the connecting base, a hinge part on the locking base, a hinge hole corresponding to the hinge part on the locking member, and a fastener at the bottom of the connecting base that passes through the limiting groove and the hinge hole in sequence and connects to the hinge part.

[0009] As described above, a quick-release adjustment device for a drawer slide rail has a locking part on its side end that can be locked in conjunction with the slide rail. The locking part has a receiving cavity on the side facing the connecting base. The elastic part is placed in the receiving cavity, and one end of it abuts against the inner wall of the receiving cavity.

[0010] As described above, in a quick-release adjustment device for a drawer slide, the elastic part is integrally formed with the locking base.

[0011] As described above, a quick-release adjustment device for a drawer slide rail has a slot on the connecting base and a buckle on the locking base that can be connected to the slot. The width of the slot is greater than the width of the buckle to facilitate the lateral adjustment of the locking base relative to the connecting base.

[0012] As described above, a quick-release adjustment device for a drawer slide rail has a first limiting part on the locking base, and a second limiting part at one end of the locking member that can abut against the first limiting part to limit its rotation range.

[0013] As described above, a quick-release adjustment device for a drawer slide rail includes a lateral adjustment mechanism comprising a threaded groove on the connecting base, a lateral adjustment member on the threaded groove, and a first helical mounting position corresponding to the threaded groove on the locking base facing the connecting base. The lateral adjustment member includes a helical segment threadedly connected to the threaded groove, and an operating part connected to the helical segment. A first adjustment hole is provided on the locking base for the operating part to be exposed. When the operating part is rotated, the locking base moves relative to the connecting base along the axial direction of the helical segment.

[0014] As described above, in a quick-release adjustment device for a drawer slide, the locking element has an anti-slip protrusion on its side.

[0015] As described above, a quick-release adjustment device for drawer slides is provided on the connecting base, which is also equipped with a height adjustment mechanism for adjusting the height of the drawer.

[0016] As described above, a quick-release adjustment device for a drawer slide rail includes a height adjustment mechanism comprising a sliding adjustment block. A corresponding sliding mounting position is provided on the connecting base. The sliding adjustment block includes a wedge-shaped block, one end of which is connected to a transition section. A screw is fixedly connected to one end of the transition section. The screw is threadedly connected to a threaded knob. A second helical mounting position is provided on the connecting base to accommodate the screw and the threaded knob. A mounting cover is detachably connected to the connecting base relative to the sliding mounting position and the second helical mounting position. A second adjustment hole is provided on the mounting cover to expose the threaded knob.

Detailed Implementation Methods

[0028] To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0029] Please see Figures 1 to 8 This embodiment provides a quick-release adjustment device for drawer slides, including a connecting base 1 that can be fixed to the bottom of the drawer. The connecting base 1 is provided with a horizontal adjustment mechanism 2. The horizontal adjustment mechanism 2 is movably connected to a locking device 3 for fixing the slide. The locking device 3 includes a locking base 31 that can cooperate with the horizontal adjustment mechanism 2 to generate horizontal displacement. The locking base 31 is hinged with a locking member 32 that can be switched to a locked state with the slide by a toggle. An elastic part 33 is provided between the locking base 31 and the locking member 32 to keep the two relatively stationary.

[0030] Specifically, the quick-release adjustment device for the drawer slide rails in this embodiment includes a connecting base 1. This connecting base 1 is conveniently fixed to the bottom of the drawer or other components requiring slide rail installation, for example, by using screws through screw holes. A lateral adjustment mechanism 2 is provided on the connecting base 1. This lateral adjustment mechanism 2 allows for fine-tuning of the lateral position of subsequently connected components. In this embodiment, the lateral adjustment mechanism 2 can be a lateral groove provided on the connecting base 1, which, in conjunction with a corresponding slider or threaded adjustment structure, achieves lateral displacement.

[0031] A locking device 3 is movably connected to the horizontal adjustment mechanism 2. The core function of the locking device 3 is to quickly lock or release the drawer slide (not shown in the figure) and allow position adjustment via the horizontal adjustment mechanism 2.

[0032] Specifically, the locking device 3 includes a locking base 31. The locking base 31 cooperates with the lateral adjustment mechanism 2. For example, the locking base 31 can be a slider that slides in the groove of the lateral adjustment mechanism 2, or it can be connected to the lateral adjustment mechanism 2 by threads, so that the entire locking device 3 can generate lateral displacement under the guidance of the lateral adjustment mechanism 2, which facilitates precise alignment with the installation position of the slide rail.

[0033] A locking element 32 is hinged to the locking base 31. The hinge structure allows the locking element 32 to rotate relative to the locking base 31. The locking element 32 is designed with a specific shape, such as having claws, protrusions, teeth, etc. When the user moves the locking element 32 with their finger or other tools, it can switch between at least two states: one state is the locked state, in which the claws or protrusions of the locking element 32 will engage or abut against specific parts of the drawer slide rail (not shown in the figure), such as the preset holes or edges on the slide rail, thereby fixing the slide rail; the other state is the unlocked state, in which the locking element 32 rotates to a position that does not interfere with the slide rail, allowing the slide rail to separate from the drawer.

[0034] To ensure the locking member 32 remains stably in either the locked or unlocked state and prevents accidental switching, an elastic portion 33 is provided between the locking base 31 and the locking member 32. In this embodiment, the elastic portion 33 can be a spring sheet, a torsion spring, or a piece of elastic rubber. When the locking member 32 is not moved to the locked or unlocked position, the elastic portion 33 provides a certain preload or forms a stable locking point, keeping the locking member 32 and the locking base 31 relatively stationary. Only when a certain external force is applied to move the locking member 32 can the force of the elastic portion 33 be overcome, and its state be switched. This not only ensures the reliability of the locking but also provides a good operating feel.

[0035] To lock the drawer and slide rails, first fix the connecting base 1 to the bottom of the drawer. Then, align the drawer and slide rails. By toggling the locking element 32 to the unlocked state, align the part of the slide rail that needs to be secured with the locking element 32, and then toggle the locking element 32 again to the locked state. The locking element 32 will then quickly lock the slide rail, completing the initial fixation. The elastic part 33 ensures that the locking element 32 remains stably in the locked state.

[0036] If lateral adjustment is required to accommodate the gap between the locking element and the fixed end of the slide rail, the locking base 31 can be slid by operating the lateral adjustment mechanism 2, causing the entire locking device 3 to move laterally towards the slide rail until it reaches a position where it can lock with the slide rail. When it is necessary to separate the drawer from the slide rail, simply move the locking element 32 again to overcome the holding force of the elastic part 33, switching it back to the unlocked state, and then separate the two.

[0037] By switching the locking element 32, the slide rail can be quickly locked and unlocked, greatly simplifying the installation and disassembly process and improving assembly efficiency, especially suitable for occasions requiring frequent adjustments or maintenance. The presence of the elastic part 33 ensures that the locking element 32 remains stable in both locked and unlocked states, preventing accidental loosening or state switching due to vibration or other reasons, thus guaranteeing connection reliability. The overall structural design is relatively simple and compact, and the operation is intuitive and easy to understand, lowering the barrier to entry for users.

[0038] Furthermore, as a preferred embodiment of this solution and not a limitation, the connecting base 1 is provided with a limiting groove 11, the locking base 31 is provided with a hinge portion 311, the locking member 32 is provided with a hinge hole 321 corresponding to the hinge portion 311, and a fastener 12 is provided at the bottom of the connecting base 1, which passes through the limiting groove 11 and the hinge hole 321 in sequence and is connected to the hinge portion 311.

[0039] In this embodiment, a limiting groove 11 is provided on the connecting base 1. This limiting groove 11 is a slender groove extending laterally, and its length determines the maximum range of lateral adjustment that the locking device 3 can perform. A hinge portion 311 is provided on the locking base 31 of the locking device 3. This hinge portion 311 is not only the structural basis for the hinged rotation of the locking member 32, but also serves as the component connecting the locking base 31 and the connecting base 1. In this embodiment, the hinge portion 311 can be a boss with internal threads or a suitable connecting hole. Correspondingly, a hinge hole 321 is provided on the locking member 32, the size and position of which are adapted to the hinge portion 311 on the locking base 31 to realize the rotation of the locking member 32 relative to the locking base 31.

[0040] A fastener 12 is provided at the bottom of the connecting base 1. The fastener 12, for example, can be a bolt or a capped screw, with its shank passing through the limiting groove 11 on the connecting base 1 from bottom to top, then through the hinge hole 321 on the locking member 32, and finally connecting with the hinge portion 311 on the locking base 31, for example, by threading.

[0041] Fastener 12 serves three functions simultaneously: firstly, it connects locking base 31 and connecting base 1; secondly, it acts as a rotation axis for locking element 32; and thirdly, it slides within the limit range of the limiting groove 11 to achieve lateral adjustment. This multi-functional integrated design reduces the number of parts and simplifies the overall structure and assembly process. The limiting groove 11 provides a clear, controlled path and a defined adjustment range for lateral adjustment, making the adjustment operation more precise and convenient.

[0042] Furthermore, as a preferred embodiment of this solution and not a limitation, the locking member 32 has a locking part 322 on its side end that can be locked in conjunction with the slide rail, and the locking member 32 has a receiving cavity 323 on the side facing the connecting base 1. The elastic part 33 is placed in the receiving cavity 323, and one end of it abuts against the inner wall of the receiving cavity 323.

[0043] In this embodiment, the locking member 32, which can be rotated by tossing, has a locking part 322 on its side end, that is, the end that interacts with the drawer slide (not shown) during the locking operation. This locking part 322 can be designed in a specific shape, such as a hook, protrusion, or pressure plate, and its shape and size are adapted to match a preset structure on the drawer slide, such as a hole, edge, or groove. The locking part 322 can effectively engage or abut against the slide, achieving reliable locking. When the locking member 32 is tossed to a certain position, both are unlocked.

[0044] In order to accommodate and position the elastic part 33, the locking member 32 has a receiving cavity 323 on its side facing the connecting base 1, providing an installation space for the elastic part 33.

[0045] An elastic part 33, such as an elastic cantilever beam, compression spring, spring sheet, or elastic rubber block, is placed inside the receiving cavity 323. At least one end of the elastic part 33 abuts against the inner wall of the receiving cavity 323, and the other end is connected to the locking base 31. When the user moves the locking member 32, causing the locking part 322 to align with the locking end of the slide rail as preset, the locking member 32 is released, and the elastic part 33 deforms, causing the locking part 322 to automatically lock with the slide rail. Conversely, the user needs to move the locking member 32 to cause the elastic part 33 to deform elastically, so that the locking part 322 can disengage from the slide rail.

[0046] Furthermore, as a preferred embodiment of this solution and not a limitation, the elastic portion 33 is integrally formed with the locking base 31. In this embodiment, the elastic portion 33 is not a separate part independent of the locking base 31, but is integrally formed with the locking base 31. This means that the locking base 31 and the elastic portion 33 are manufactured as a single component during the manufacturing process. This can be achieved by selecting suitable materials, such as engineering plastics or spring steel with good elasticity, and employing specific molding processes such as injection molding, stamping, etc.

[0047] In terms of specific structure, the elastic part 33 can be an elastic structural feature extending from the main body of the locking base 31:

[0048] Optionally, the elastic part 33 can be a cantilever beam structure with a certain length and flexibility;

[0049] Optionally, the elastic part 33 can be a curved spring part that can undergo elastic deformation under external force.

[0050] By combining the locking base 31 and the elastic part 33 into one, the total number of parts in the entire device is reduced. Since there is no need to install a separate elastic element, the assembly steps are reduced, which can improve production efficiency and reduce the possibility of assembly errors.

[0051] Furthermore, as a preferred embodiment of this solution and not a limitation, the connecting base 1 is provided with a slot 13, and the locking base 31 is provided with a buckle 312 that can be connected to the slot 13. The width of the slot 13 is greater than the width of the buckle 312 so as to allow the locking base 31 to be adjusted laterally relative to the connecting base 1.

[0052] In this embodiment, in addition to the limiting groove 11 and fastener 12 structures mentioned above, a slot 13 is additionally provided on the connecting base 1. Simultaneously, a buckle 312 correspondingly connected to the slot 13 is provided on the locking base 31. The slot 13 is designed to extend laterally, and its length in the lateral direction is greater than the dimension of the buckle 312 in that direction, allowing the buckle 312 to slide laterally within the slot 13. This engaging structure of the slot 13 and buckle 312, together with the limiting groove 11 and fastener 12, provides additional guidance for the locking base 31 during lateral adjustment, preventing unnecessary rotation or offset during sliding and making the adjustment process smoother. It should be noted that the engagement of the buckle 312 and the slot 13 itself serves to connect and fix the locking base 31 to the connecting base 1.

[0053] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the locking base 31 is provided with a first limiting part 313, and one end of the locking member 32 is provided with a second limiting part 324 that can abut against the first limiting part 313 to limit its rotation range.

[0054] In order to precisely control the rotation range of the locking member 32 relative to the locking base 31, prevent excessive rotation from causing damage to the component or failure of function, and ensure that it can accurately stop at the preset locked or unlocked position, a first limiting part 313 is provided on the locking base 31. The first limiting part 313 may be a block, a protrusion, or an edge of a specific shape protruding from the surface of the locking base 31.

[0055] Accordingly, a second limiting part 324 is provided at one end of the locking member 32, or at a position on its rotation path where it will contact the first limiting part 313. The second limiting part 324 may also be a protrusion, a specific shaped end face or edge, designed to physically abut against the first limiting part 313 on the locking base 31 when the locking member 32 rotates to the end of its stroke.

[0056] By physically limiting the movement, the locking element 32 is effectively prevented from exceeding its designed rotation range due to excessive operating force or accidental force, thereby avoiding damage to the hinge structure, the elastic part 33, or the locking element 32 itself.

[0057] Furthermore, as a preferred embodiment of this solution and not a limitation, the lateral adjustment mechanism 2 includes a threaded groove 21 provided on the connecting base 1, a lateral adjustment member 22 provided on the threaded groove 21, and a first helical mounting position 314 corresponding to the threaded groove 21 provided on the locking base 31 facing the connecting base 1. The lateral adjustment member 22 includes a helical segment 221 threadedly connected to the threaded groove 21, and an operating part 222 connected to the helical segment 221. A first adjustment hole 315 is provided on the locking base 31 to expose the operating part 222. When the operating part 222 is rotated, the locking base 31 is displaced relative to the connecting base 1 along the axial direction of the helical segment 221.

[0058] In this embodiment, a threaded groove 21 is provided on the connecting base 1. This threaded groove 21 has a threaded structure, which can be understood as a structure equivalent to a nut fixed on the connecting base and associated with the groove for threaded engagement with the adjusting component. A lateral adjusting component 22 is provided in the threaded groove 21. The lateral adjusting component 22 is the core component for realizing the adjustment action. It includes a helical segment 221, which has an external thread that matches the internal thread of the threaded groove 21, so that the helical segment 221 can be threadedly connected to the threaded groove 21. The helical segment 221 is also connected to an operating part 222, which is the part for the user to apply rotational torque. For example, it can be a knob, a screw head, or other structure that is easy to operate manually or with tools.

[0059] On the locking base 31, on the side facing the connecting base 1, there is a first helical mounting position 314 corresponding to the threaded groove 21. The function of this first helical mounting position 314 is to establish a kinematic connection between the locking base 31 and the lateral adjustment member 22, but it does not usually directly participate in the threaded engagement. For example, it can be a smooth through hole or a groove / ring structure that can constrain a part of the lateral adjustment member 22, such as a collar or a non-threaded section, so that the lateral adjustment member 22 can rotate relative to the locking base 31, but in the axial direction, i.e., the lateral adjustment direction, the locking base 31 will move with the axial position change of the lateral adjustment member 22.

[0060] Meanwhile, a first adjustment hole 315 is provided on the locking base 31. The position and size of this hole are designed so that the operating part 222 of the lateral adjustment member 22 can pass through or be exposed, making it convenient for the user to access and rotate the operating part 222 from the outside of the locking base 31.

[0061] The threaded drive mechanism can convert rotational motion into minute linear displacement, thereby achieving very precise lateral position adjustment. It also has self-locking properties, meaning that once the adjustment is in place, even if subjected to a certain external force or vibration, the locking base 31 can maintain its position without the need for additional locking steps to fix the adjustment position.

[0062] Furthermore, as a preferred embodiment of this solution and not a limitation, the locking member 32 has an anti-slip protrusion 325 on its side end. The locking member 32 is a component that the user directly moves to switch the slide rail locking state. In order to facilitate the user to apply force and prevent the fingers from slipping during operation, in particular, in this embodiment, the side end of the locking member 32, that is, the area where the user's fingers or tools contact the moving operation, is provided with an anti-slip protrusion 325.

[0063] The anti-slip protrusion 325 can be one or more surface features designed to increase contact friction, for example:

[0064] One or more ribs arranged in a certain direction;

[0065] A knurled area;

[0066] A series of small dots or diamond-shaped protrusions;

[0067] Or other forms of roughening, textured surface structures.

[0068] The anti-slip protrusions 325 increase the coefficient of friction between the user's fingers and the contact surface of the locking element 32, providing better grip. Even if the user's fingers are oily, wet, or wearing gloves, it is easier to apply sufficient force to the locking element 32, making the operation of the entire quick-release adjustment device more convenient, comfortable, and user-friendly.

[0069] Furthermore, as a preferred embodiment of this solution and not a limitation, the connecting base 1 is also provided with a height adjustment mechanism 4 for adjusting the height of the drawer. The height adjustment mechanism 4 includes a sliding adjustment block 41. The connecting base 1 is provided with a corresponding sliding mounting position 14. The sliding adjustment block 41 includes a wedge block 411 that can extend between the slide rail and the bottom of the drawer. One end of the wedge block 411 is connected to a transition section 412. One end of the transition section 412 is fixedly connected to a screw 413. The screw 413 is threadedly connected to a threaded knob 414. The connecting base 1 is provided with a second spiral mounting position 15 that accommodates the screw 413 and the threaded knob 414. The connecting base 1 is detachably connected with a mounting cover 16 relative to the sliding mounting position 14 and the second spiral mounting position 15. The mounting cover 16 is provided with a second adjustment hole 161 for the threaded knob 414 to be exposed. When the threaded knob 414 is rotated, the wedge block 411 extends into the slide rail and the bottom of the drawer, causing the distance between them to change.

[0070] In this embodiment, the connecting base 1 not only has the aforementioned lateral adjustment mechanism 2 and locking device 3, but also additionally has a structure for installing and accommodating the height adjustment mechanism 4. The height adjustment mechanism 4 includes a sliding adjustment block 41, which is installed in the sliding mounting position 14 of the connecting base 1 and can slide along the sliding mounting position 14. The key functional part of the sliding adjustment block 41 is a wedge block 411. This wedge block 411 is designed with an inclined surface, and its position is set to extend into the gap between the installed drawer slide rail and the bottom of the drawer.

[0071] The wedge block 411 is connected to a screw 413 via a transition section 412. The screw 413 is fixedly connected to the transition section 412, forming an integral extension of the sliding adjusting block 41. A second helical mounting position 15 is also provided on the connecting base 1. This second helical mounting position 15 is used to accommodate the aforementioned screw 413 and a threaded knob 414 threadedly connected to it. The structure of the second helical mounting position 15 constrains the threaded knob 414, allowing it to rotate but preventing or making axial displacement difficult.

[0072] To protect the internal mechanisms, a mounting cover 16 is detachably connected to the connecting base 1. This mounting cover 16 covers the sliding mounting position 14 and the second screw mounting position 15. A second adjustment hole 161 is provided on the mounting cover 16, the position of which corresponds to the threaded knob 414, so that a part of the threaded knob 414 is exposed, making it convenient for the user to rotate it through this hole.

[0073] When the drawer height needs to be adjusted, the user can use a suitable tool or their fingers to rotate the threaded knob 414 through the second adjustment hole 161. Since the threaded knob 414 is constrained to rotate only by the second screw mounting position 15 and the mounting cover 16, its rotation forces the threaded screw 413 to move axially. The axial movement of the screw 413 causes the entire sliding adjustment block 41, which is fixed to it, to slide within the sliding mounting position 14. As the sliding adjustment block 41 slides, the depth to which the wedge block 411 extends into the gap between the drawer slide rail and the bottom of the drawer changes. Due to the wedge-shaped surface of the wedge block 411, its linear sliding is converted into a change in the vertical pushing force on the bottom of the drawer. When the wedge block 411 extends deeper, it forces the bottom of the drawer to rise relative to the slide rail; when it retracts, it allows the bottom of the drawer to fall relatively. This achieves the adjustment of the drawer height.

[0074] With the addition of height adjustment mechanism 4, in addition to enabling quick installation / removal and lateral adjustment, height adjustment function is further integrated, making drawer installation and adjustment more comprehensive and convenient.

[0075] Working principle of this utility model:

[0076] This embodiment discloses a quick-installation adjustment device for drawer slides, the core of which lies in quick locking and multi-directional adjustment. The main body of the device is fixed to the bottom of the drawer via a connecting base. The key locking device is movably connected to the base and includes a locking element that can be hinged and rotated around the locking base. By moving the locking element, the user can quickly engage or disengage the locking part from the preset position of the slide rail, achieving quick installation and removal of the slide rail. The presence of an elastic part ensures that the locking element can be stably maintained in the locked or unlocked position, preventing accidental loosening. To achieve precise positioning, the entire locking device can be moved left and right relative to the connecting base via a lateral adjustment mechanism. Furthermore, a height adjustment mechanism is also integrated. By rotating the threaded knob, the screw and sliding adjustment block connected to it are moved, causing the wedge block to extend into or retract from the gap between the bottom of the drawer and the slide rail, thereby conveniently adjusting the vertical height of the drawer using the wedge principle.

[0077] In summary, this device combines manual quick locking, lateral fine-tuning, and optional height adjustment functions, significantly improving the efficiency, accuracy, and convenience of drawer installation.

[0078] The above are implementation methods provided in conjunction with specific content, and it is not intended that the specific implementation of this application is limited to these descriptions. Any methods or structures that are similar to those of this application, or any technical deductions or substitutions made based on the concept of this application, should be considered within the scope of protection of this application.
