Description

Technical Field

[0001] This utility model relates to the field of modern furniture technology, and in particular to a cabinet hinge. Background Technology

[0002] In the field of modern furniture manufacturing, especially in the design and production of cabinets, hinges are key hardware components that connect the cabinet body and cabinet doors and enable the opening and closing functions.

[0003] Traditional cabinet hinges typically use screws to attach the fixed and movable hinge blades to the cabinet body and door respectively. While this method provides a secure connection, it has significant drawbacks: First, the installation process is cumbersome, requiring screwdrivers and other tools for precise hole alignment, which is time-consuming and labor-intensive, impacting production and installation efficiency. Second, when disassembling the cabinet door for repair, cleaning, or replacement, the screws must be unscrewed. Repeated disassembly and reassembly can enlarge the mounting holes, damage the board material, and lead to loose connections, door sagging, and other problems, affecting the lifespan and aesthetics of the cabinet. Utility Model Content

[0004] The purpose of this invention is to provide a hinge with a stable structure and more convenient operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cabinet hinge, comprising a fixed blade and a movable blade that are hinged together, wherein the fixed blade and the movable blade are connected to the cabinet body and the cabinet door through a quick-release structure, wherein the quick-release structure comprises a receiving component and an inserting component; The insertion assembly includes a mounting base with a central insertion hole, a strip hole perpendicular to the insertion hole axis and connected to the insertion hole on the mounting base, a first insertion block slidably disposed in the strip hole, and a first return spring disposed in the strip hole for applying a spring force toward the center of the insertion hole to the first insertion block. The insertion assembly includes a plug rod that mates with a socket, and the outer wall of the plug rod has a circular hole corresponding to the first plug block; When the insertion rod is inserted into the insertion hole to the predetermined position, the first insertion block is engaged in the round hole under the action of the first reset spring.

[0006] This technical solution has fewer parts, a simpler structure, and is easier to manufacture and assemble, which helps reduce manufacturing costs and improves overall reliability due to fewer steps. During installation, simply align the insert rod and insert it into the socket of the mounting base. During insertion, the outer wall of the insert rod slides back the first insert block through contact. Once in place, the first insert block automatically springs into the round hole under spring pressure, completing the locking process. The entire process is completed in one step, requiring no screwdrivers or other tools, significantly improving installation efficiency. After locking, the first insert block radially engages with the round hole of the insert rod, forming a rigid mechanical interlock with the mounting base and the insert rod. This effectively resists axial pull-out forces, shaking, and vibrations generated by the cabinet door during daily use, avoiding the loosening and sagging problems that easily occur in traditional screw connections due to repeated stress, ensuring long-term stability.

[0007] As a further description of the above technical solution: the insertion assembly also includes a movable rod that can be axially slidably disposed in the inner cavity of the insertion rod, a second return spring disposed in the inner cavity of the insertion rod for pushing the movable rod to reset, a second insertion block radially disposed on the movable rod, and a third return spring for applying a radially outward elastic force to the second insertion block.

[0008] As a further description of the above technical solution: when the moving rod is pressed to the predetermined position, the second insert block, under the action of the third reset spring, pushes out the first insert block through the round hole to release the lock.

[0009] As a further description of the above technical solution: at least two strip holes are symmetrically arranged around the insertion hole on the mounting base, and at least two round holes are correspondingly opened on the outer wall of the insertion rod.

[0010] As a further description of the above technical solution: the outer edge of the insertion end of the insertion rod is provided with a tapered inclined surface, which is used to overcome the elastic force of the first reset spring and press the first insertion block back into the strip hole during the insertion of the insertion rod into the insertion hole.

[0011] As a further description of the above technical solution: the end of the first insertion block facing the center of the insertion hole has a hemispherical structure for sliding contact with the insertion rod.

[0012] As a further description of the above technical solution: the moving rod has a radial cylindrical groove on its body, and the second insert block and the third return spring are installed in the cylindrical groove; The second insert is compressed into the cylindrical groove by being limited by the inner wall of the insert rod.

[0013] As a further description of the above technical solution: the end of the insertion rod away from its insertion end is provided with a flange, and after the insertion rod is fully inserted, the flange abuts against the surface of the fixed blade or the movable blade.

[0014] Beneficial effects: 1. The hinge installation process requires no tools; simply align the insert component with the pre-installed receiving component and push it in. Disassembly is simple; just press the end of the moving rod to unlock and pull it out. The operation is easy and significantly improves the efficiency of installation and disassembly.

[0015] 2. In the locked state, the insertion rod of the insertion component is rigidly engaged with the mounting base of the inserted component through multiple symmetrically distributed first insertion blocks. This radial locking method distributes the force evenly and can effectively resist tension, torque and vibration from all directions, ensuring the long-term stability of the cabinet door and cabinet body connection, and avoiding the loosening problem that may occur with traditional screw connections.

[0016] 3. Unlocking is achieved by pressing the exposed moving lever. The operation point is clear and the feedback is clear. Compared with some hidden switches or buckles that require going deep into the cabinet to find and operate, this design is more ergonomic and can be easily disassembled even in poor lighting or confined space.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5This utility model provides a cabinet hinge for connecting the cabinet body 10 and the cabinet door 11. The hinge includes a fixed blade 12 and a movable blade 13 that are hinged together. The fixed blade 12 and the movable blade 13 are respectively fixed to the cabinet body 10 and the cabinet door 11 by a quick-release structure. The quick-release structure includes an insert component and an insert receiving component that cooperate with each other.

[0025] The insertion assembly is used to pre-install in the plate of the cabinet 10 or cabinet door 11, including a mounting base 14. The mounting base 14 is made by injection molding, metal processing or other methods, and is installed in the reserved hole of the cabinet 10 or cabinet door 11 by inlay, adhesive or screw fixing.

[0026] The mounting base 14 has a circular insertion hole at its center for accommodating and guiding the insertion of the component. Inside the mounting base 14, at least two strip holes 141 are symmetrically arranged around the insertion hole. In this embodiment, it is preferable to provide two strip holes 141 that are symmetrically distributed at 180 degrees. The axis of the strip hole 141 is perpendicular to the axis of the insertion hole, and its inner end is connected to the inner wall of the insertion hole.

[0027] Each slot 141 is slidably fitted with a first insert 15. The shape of the first insert 15 is adapted to the inner cavity of the slot 141, and its end facing the center of the socket is a hemispherical surface so as to cooperate with the insertion component. A first return spring 16 is installed between the first insert 15 and the bottom wall of the inner cavity of the slot 141. The first return spring 16 always applies an elastic thrust to the first insert 15 toward the center of the socket. In its natural state, the part of the first insert 15 is driven to extend into the space of the socket.

[0028] The insertion assembly includes a hollow insertion rod 17, the outer diameter of which matches the inner diameter of the insertion hole of the mounting base 14. One end of the insertion rod 17 is provided with a flange. When the insertion rod 17 is fully inserted into the insertion hole, the flange abuts against the surface of the corresponding blade, thereby axially positioning the blade and ensuring the stability of the installation.

[0029] On the outer wall of the insertion rod 17, at least two circular holes 171 are provided, which correspond to the positions of the first insertion block 15 of the insertion assembly. When the insertion rod 17 is inserted to a predetermined depth, these circular holes 171 are aligned with the strip hole 141 to accommodate the insertion of the first insertion block 15.

[0030] A movable rod 18 is slidably installed in the hollow inner cavity of the insertion rod 17. The outer diameter of the movable rod 18 is smaller than the inner diameter of the insertion rod 17, and it can slide back and forth axially in the inner cavity of the insertion rod 17. A second return spring 19 is installed between the bottom of the inner cavity of the insertion rod 17 and the inner end of the movable rod 18. The second return spring 19 is used to push the movable rod 18 to move away from the inner cavity of the insertion rod 17, so that it remains in the extended state in its natural state.

[0031] The moving rod 18 has at least two radial cylindrical grooves, in which a second insert 20 is installed. A third return spring 21 is installed between the second insert 20 and the bottom of the cylindrical groove. The third return spring 21 always applies a radially outward elastic thrust to the second insert 20. In its natural state, the second insert 20 is compressed and housed in the cylindrical groove due to the limitation of the inner wall of the insert rod 17.

[0032] To facilitate insertion, the outer edge of the insertion end of the insertion rod 17 (i.e. the end that first enters the insertion hole) is provided with a tapered guide slope; similarly, the rod body of the moving rod 18 is also provided with a slope structure for cooperating with the first insertion block 15, so as to push the first insertion block 15 when unlocking.

[0033] Usage steps: Align the insertion component with the insertion hole of the receiving component pre-embedded in the cabinet 10 or cabinet door 11, and push the insertion rod 17 forward. The inclined surface at its end first contacts the hemispherical surface of the two first insertion blocks 15 that are pushed out by the first return spring 16. As the insertion rod 17 continues to go deeper, the inclined surface will generate a radially outward component force. This component force overcomes the elastic force of the first return spring 16 and presses the two first insertion blocks 15 back into their respective strip holes 141, thereby making way for the insertion rod 17.

[0034] When the insertion rod 17 is pushed to the predetermined depth, the circular hole 171 on its outer wall moves to a position that is completely aligned with the first insertion block 15. At this time, without the obstruction of the outer wall of the insertion rod 17, the two first insertion blocks 15 are pushed inward by the first return spring 16, and their heads extend into and are locked in the circular hole 171 of the insertion rod 17. At this time, the first insertion block 15 forms a rigid connection with the mounting base 14 and the insertion rod 17, thereby firmly locking the entire insertion assembly in the mounting base 14 and completing the rapid installation of the hinge blade.

[0035] When unlocking, press the exposed end of the moving rod 18 with your finger. The moving rod 18 is pressed into the inner cavity of the insert rod 17 and compresses the second return spring 19 inside it. As the moving rod 18 goes deeper axially, the second insert block 20 inside it also moves.

[0036] When the moving rod 18 is pressed to the predetermined position, the second insert 20 on it moves to the position aligned with the circular hole 171 of the insert rod 17 and the first insert 15. At this time, under the action of the third return spring 21, the second insert 20 will pop out radially and pass through the circular hole 171, but will not enter the strip hole 141. This popping action will apply a strong radial outward pushing force to the first insert 15 which is in the circular hole 171.

[0037] The thrust overcomes the elastic force of the first return spring 16, pushing the first insert 15 completely out of the round hole 171 and back into the strip hole 141. At this time, the locking state between the insert rod 17 and the mounting base 14 is released.

[0038] While holding the moving rod 18 in place, pull the entire insertion assembly outward to easily remove the blade. After releasing the moving rod 18, press the second insertion block 20 through the round hole 171. The second insertion block 20 retracts, and the second return spring 19 pushes the moving rod 18 back to its original position, restoring the entire device to standby mode.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
