Description

Technical Field

[0001] This invention belongs to the field of hinge technology, and specifically relates to a high-efficiency detachable snap-fit ​​hinge. Background Technology

[0002] Hinges, as connectors between cabinet doors and cabinet bodies, typically do not have their hinge cups, bases, and arms easily disassembled after manufacturing. Therefore, during installation, the hinge cup is usually connected to the cabinet door first, then the door and hinge are brought close to the cabinet body, and finally the base is fixed to the cabinet side wall to complete the connection. This installation method requires the installer to hold the cabinet door with one hand and tighten screws to secure the base to the cabinet side wall with the other, increasing the difficulty and labor intensity of installation. Furthermore, holding the door with one hand makes it difficult to ensure proper alignment, potentially leading to misalignment. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to propose a high-efficiency snap-fit ​​hinge that facilitates the disassembly and assembly of cabinet doors. Using this hinge can reduce the installation difficulty and labor intensity for installers.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a high-efficiency detachable snap-fit ​​hinge, comprising a hinge cup, a hinge arm, and a base, wherein the front end of the hinge arm is hinged to the hinge cup, and the rear end of the hinge arm is movably connected to the base. The base is provided with a button, the button is provided with a hook, and the button is hinged to the base through a first pin, so that the button can rotate relative to the base around the first pin. The rear end of the hinge arm is placed on the base, and the rear end of the hinge arm is provided with a latch corresponding to the position of the hook. By rotating the button, the hook can be engaged and disengaged from the latch of the hinge arm.

[0005] When using the aforementioned hinge, simply turn the button to disengage the hook from the hinge arm, easily detaching the hinge arm from the base. At this point, the hinge cup can be individually fixed to the cabinet door, and the base to the cabinet body. Then, by holding the cabinet door, the hinge arm can be connected to the base. This eliminates the need for installers to hold the cabinet door while fixing the base to the cabinet body, reducing installation difficulty and labor intensity. Furthermore, since the base is pre-fixed independently to the cabinet body, its installation position is easily guaranteed, ensuring alignment between the cabinet door and the cabinet body, thus improving installation efficiency. The disassembly and assembly of the hinge arm and base are achieved entirely by turning the button, making cabinet door assembly and disassembly convenient and efficient.

[0006] Furthermore, the base has a snap-fit ​​at its front end, and the hinge arm has a second pin. When the button's hook engages with the hinge arm's latch, the snap-fit ​​at the front end of the base engages with the second pin of the hinge arm. By pushing the hinge arm backward, the second pin automatically engages with the snap-fit ​​at the front end of the base, making assembly convenient and ensuring a more stable fit between the hinge arm and the base.

[0007] Furthermore, the buckle is a protrusion on the left and right sides of the rear end of the hinge arm, and the left and right ends of the button are respectively provided with hooks. The hooks on the left and right ends of the button are respectively fastened to the outside of the protrusion on the left and right sides of the hinge arm, so that the connection between the hinge arm and the base is more stable.

[0008] Furthermore, the first pin is also fitted with a torsion spring, with its two legs abutting against the button and the base, respectively. The torsion spring provides a restoring force to the button, ensuring that the hook and protrusion are not easily disengaged after engagement, and that the hook automatically resets as the button rotates.

[0009] Furthermore, the rear end of the hinge arm is provided with a latch. When the hinge arm moves backward relative to the base, the latch can abut against the button and push the button to rotate in the direction where the hook disengages from the protrusion, so that the protrusion can slide to the position where it engages with the hook. When the protrusion slides to the position where it engages with the hook, the button returns to its original position under the action of the torsion spring, causing the button's hook to automatically engage with the outside of the protrusion on the hinge arm. This solution eliminates the need for manual button operation when assembling the hinge arm and the base, making assembly more convenient.

[0010] Furthermore, the base includes a bottom plate, a middle plate, and a top plate stacked sequentially. The middle plate is movably connected to the bottom plate, and the top plate is movably connected to the middle plate. The rear end of the hinge arm is positioned on the top side of the top plate. The button is hinged to the rear end of the top plate via a first pin. When the button's hook engages with the hinge arm's latch, the front end of the top plate is still engaged with the hinge arm. This design allows for fine-tuning of the cabinet door's vertical and horizontal position relative to the cabinet body through relative displacement between the middle plate and the bottom plate, and between the top plate and the middle plate.

[0011] The hinge of this invention can be installed separately on the cabinet door and the cabinet body, and can be reassembled completely by the quick connection structure between the hinge arm and the base, thereby achieving a quick connection between the cabinet door and the cabinet body. Furthermore, the cabinet door can be easily disassembled by turning the button to release the hook and the protrusion. Compared with existing hinges, the hinge of this invention can reduce the installation difficulty and labor intensity of installers, and improve installation efficiency. Attached Figure Description

[0024] Example

[0025] like Figure 1-10As shown, this embodiment provides a high-efficiency detachable snap-fit ​​hinge A, including a hinge cup 1, a hinge arm 2, and a base 3. The base 3 includes a bottom plate 32, a middle plate 33, and a top plate 34 stacked sequentially. The front and rear edges of the bottom plate 32 are respectively provided with guide grooves 321. The middle plate 33 is placed on top of the bottom plate 32, and its front and rear edges mate with the guide grooves 321. The middle plate 33 and the bottom plate 32 are also connected by a first eccentric rivet 71. By rotating the first eccentric rivet 71, the middle plate 33 can slide relative to the bottom plate 32 along the length of the guide grooves 321. The left and right edges of the middle plate 33 are respectively provided with baffles 33. 1. The baffle 331 is provided with a guide post 332. The top plate 34 is placed on the top side of the middle plate 33 and located between the two baffles 331. The left and right edges of the top plate 34 are respectively provided with top plate side plates 341. The top plate side plates 341 are provided with sliding grooves 3411 that cooperate with the guide post 332 at the corresponding positions. The top plate 34 and the middle plate 33 are also connected by a second eccentric rivet 72. In this way, by rotating the second eccentric rivet 72, the top plate 34 can slide relative to the middle plate 33 along the length direction of the sliding groove 3411. In addition, the rear end of the top plate 34 is provided with a button 4. The left and right ends of the button 4 are respectively provided with hooks 41. The button 4 is hinged to the rear end of the top plate 34 through a first pin 51, so that the button 4 can rotate relative to the rear end of the top plate 34 around the first pin 51. The front end of the top plate 34 is provided with a latch 31.

[0026] The front end of the aforementioned hinge arm 2 is hinged to the hinge cup 1. The rear end of the hinge arm 2 has hinge arm side plates 20 on both sides. The rear end of the hinge arm 2 is placed on the top side of the top plate 34. The rear end of the hinge arm 2 is provided with a buckle 21 corresponding to the position of the buckle 41. The buckle 21 can be a buckle hole or a protrusion. By rotating the button 4, the buckle 41 can be engaged with and disengaged from the buckle 21 of the hinge arm 2. When the buckle 41 of the button 4 is engaged with the buckle 21 of the hinge arm 2, the latch 31 at the front end of the top plate 34 is also engaged with the hinge arm 2.

[0027] When using the above-mentioned hinge, turn button 4 to disengage hook 41 from latch 21 of hinge arm 2, and hinge arm 2 can be easily separated from base 3. At this time, hinge cup 1 can be fixed to cabinet door 8 and base 3 can be fixed to cabinet body 9. Then, hold cabinet door to reconnect hinge arm 2 and base 3. In this way, installers do not need to hold cabinet door 8 to fix base 3 to cabinet body 9, reducing the installation difficulty and labor intensity of installers.

[0028] As an improvement to this embodiment, a second pin 52 is provided between the front ends of the two hinge arm side plates 20. When the hook 41 of the button 4 is engaged with the latch 21 of the hinge arm 2, the latch 31 at the front end of the top plate 34 is engaged with the second pin 52 of the hinge arm 2. Furthermore, in this embodiment, the latch 21 is a protrusion located on the outer side of the rear end of the two hinge arm side plates 20. Thus, by having the hooks 41 at both ends of the button 4 engage with the outer side of the protrusion on the outer side of the two hinge arm side plates 20, and then by having the latch 31 at the front end of the top plate 34 engage with the second pin 52 of the hinge arm 2, the hinge arm 2 can be securely connected to the base 3, ensuring the reliability of the connection between the cabinet door 8 and the cabinet body 9.

[0029] The first pin 51 mentioned above is also fitted with a torsion spring 6. The two legs of the torsion spring 6 abut against the button 4 and the top plate 34 respectively. The rear ends of the two hinge arm side plates 20 are respectively provided with a latch 22. When the hinge arm 2 moves backward relative to the base 3, the latch 22 can abut against the button 4 and push the button 4 to rotate in the direction of disengaging the hook 41 from the protrusion, so that the protrusion can slide to the position of engaging with the hook 41. When the protrusion slides to the position of engaging with the hook 41, the button 4 is reset under the action of the torsion spring 6, causing the hook 41 of the button 4 to automatically engage with the outside of the protrusion of the hinge arm 2. Specifically, the side of the latch 22 that abuts against the button 4 is arched, forming a contact point. As the hinge arm 2 moves backward relative to the base 3, the contact point between the latch 22 and the button 4 slides on the arched side of the latch 22. This causes the button 4 to first rotate in the direction where the hook 41 disengages from the protrusion (hereinafter referred to as the "opening direction"). After the contact point between the latch 22 and the button 4 slides to the highest position on the arched side of the latch 22, the button 4 returns to its original position under the action of the torsion spring 6 and automatically rotates in the direction where the hook 41 approaches the protrusion (hereinafter referred to as the "closing direction") until the hook 41 of the button 4 engages with the outside of the protrusion of the hinge arm 2. This allows for automatic assembly of the hinge arm 2 and the base 3 without manual operation of the button 4, making assembly more convenient. If it is necessary to disassemble the hinge arm 2 and the base 3, the button 4 can be manually rotated in the opening direction to disengage the hook 41 from the protrusion, and then the hinge arm 2 can be moved forward relative to the base 3 to complete the disassembly. Therefore, disassembly of the hinge arm 2 and the base 3 is also convenient.

[0030] When using the hinge in this embodiment, first turn button 4 in the opening direction to disengage hook 41 from the protrusion, disassemble hinge arm 2 from base 3, then fix hinge cup 1 separately to cabinet door 8 and base 3 separately to cabinet body 9. Finally, hold cabinet door 8 and move hinge arm 2 backward relative to base 3 until hook 41 of button 4 engages with protrusion of hinge arm 2 and latch 31 of top plate 34 and second pin 52 of hinge arm 2. At this time, hinge arm 2 and base 3 are reassembled to complete the connection between cabinet door 8 and cabinet body 9. If it is necessary to disassemble cabinet door 8, first turn button 4 in the opening direction to disengage hook 41 from protrusion, then hold cabinet door 8 and move hinge arm 2 forward relative to base 3. At this time, latch 31 of top plate 34 also disengages from second pin 52 of hinge arm 2, disassemble hinge arm 2 from base 3, and complete the disassembly of cabinet door 8. After the cabinet door 8 is connected to the cabinet body 9, if it is necessary to fine-tune the position of the cabinet door 8, the first eccentric rivet 71 and the second eccentric rivet 72 can be rotated respectively to achieve fine-tuning of the cabinet door 8 relative to the cabinet body 9 in the vertical and horizontal positions.

[0031] The embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
