Description

Technical Field

[0001] This utility model relates to the field of furniture hinges, specifically to a quick-installation structure for hinges. Background Technology

[0002] Currently, hinges include a hinge arm, a hinge cup, and a base. The base is used to install on the cabinet body, and the hinge cup is used to install on the cabinet door. The hinge cup is hinged to the front end of the hinge arm, and the hinge arm connects to the base. To facilitate quick installation or separation of the cabinet door and the cabinet body, the mounting base of some hinges is detachable. The mounting base is fixed to the inner wall of the cabinet body by self-tapping screws, such as the "Quick-install Furniture Hinge" in Chinese Utility Model Patent Publication No. CN215485431U. This hinge has a latch with a positioning hook. The positioning hook engages with a second fork, and the first fork is adapted to a second positioning pin. A compression spring is provided between the latch and the inner arm to drive the positioning hook to engage with the second fork. The positioning hook can swing away from the second fork, and the first fork can disengage from the second positioning pin. The assembly process of the mounting base and the inner arm... The process involves first using your finger to swing the latch counterclockwise, shortening the compression spring. Then, the first fork connects to the second positioning pin. Releasing the latch causes the spring's restoring force to swing it clockwise, engaging the positioning hook into the second fork. When the door panel needs to be removed from the cabinet, you can use your finger to swing the latch counterclockwise, disengaging the positioning hook from the second fork. Then, pull the hinge arm to the left (in practical applications, this means moving the hinge arm and inner arm forward together relative to the cabinet), disengaging the first fork from the second positioning pin. This allows for convenient and quick installation and removal of the door panel. However, this installation structure is a one-way installation structure, meaning the front end of the inner wall must first connect to the front end of the mounting base. This single installation method is not conducive to flexible cabinet door installation, so existing hinge technology needs improvement. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a hinge quick-installation structure, which is more conducive to the flexible installation of cabinet doors.

[0004] The objective of this utility model is achieved through the following technical solution.

The upper and lower ends of the inner arm top plate are integrally connected to the corresponding inner arm side plates. The locking hook is disposed between the upper and lower inner arm side plates. The limiting protrusion can be abutted against the inner arm top plate by the elastic restoring force of the locking spring on the locking hook.

[0009] Preferably, the inner arm side plate includes a baffle portion, which abuts against the outer side of the front buckle tooth and the locking hook.

[0010] Preferably, the locking spring on the hook is a torsion spring, which is sleeved on the hinge pin of the hook. One end of the locking spring is connected to the hook, and the other end of the locking spring is connected to the inner arm.

[0011] Preferably, the base assembly has a positioning groove, the inner arm has a positioning shaft, the positioning shaft extends in the vertical direction, and the positioning shaft is adapted to be disposed in the positioning groove.

Detailed Implementation

[0028] The present invention will now be further described with reference to the accompanying drawings.

[0029] The hinge quick-installation structure of this utility model, such as Figures 1 to 4 As shown, the assembly includes a base assembly 1 and a hinged arm assembly 2. The base assembly 1 is used to install and connect the cabinet body, and the hinged arm assembly 2 is used to hinge a hinge cup 3. The hinge cup 3 is used to install on the back of the cabinet door. A latch 6 is hinged to the rear of the hinged arm assembly 2, so the latch 6 can swing relative to the hinged arm assembly 2. A hook 7 is hinged to the front of the hinged arm assembly 2, so the hook 7 can swing relative to the hinged arm assembly 2. The rear end of the base assembly 1 is provided with a rear latch tooth 121, and the front end of the base assembly 1 is provided with a front latch tooth 122. Figure 1 As shown, when the base assembly 1 and the hinge arm assembly 2 are connected, that is, when the hinge is in use, the latch 6 engages with the rear latch tooth 121, and the latch hook 7 engages with the front latch tooth 122. Figure 1 As shown, the latch 6 is connected to a latch locking spring 63 for driving the latch 6 to swing. In other words, the latch locking spring 63 can drive the latch 6 to swing counterclockwise so that the latch 6 locks onto the rear latch tooth 121. The hook 7 is connected to a hook locking spring 73 for driving the hook 7 to swing. In other words, the hook locking spring 73 can drive the hook 7 to swing clockwise so that the hook 7 locks onto the front latch tooth 122.

[0030] like Figure 3 and Figure 4 As shown, the base assembly 1 and the hinged arm assembly 2 can be detached and separated. Figure 5As shown, the first installation operation of the base assembly 1 and the hinge arm assembly 2 is as follows: First, install the base assembly 1 on the inner wall of the cabinet door using self-tapping screws, install the hinge cup 3 on the back of the cabinet door, then tilt the hinge arm assembly 2 relative to the base assembly 1, and then move the rear end of the hinge arm assembly 2 towards the inner wall of the cabinet. At this time, the latch 6 is located behind the rear latch tooth 121. Then move the hinge arm assembly 2 forward so that the rear latch tooth 121 is inserted into the latch 6, that is, make the latch 6 engage with the rear latch tooth 121. Then swing the latch hook 7 counterclockwise (the latch hook locking spring 73 further elastically deforms), and then swing the front end of the hinge arm assembly 2 towards the inner wall of the cabinet, releasing the latch hook 7. The elastic restoring force of the latch hook locking spring 73 drives the latch hook 7 to swing clockwise. Thus, as shown... Figure 1 As shown, the locking hook 7 is fastened onto the front locking tooth 122, meaning that the front locking tooth 122 is inserted into the locking hook 7, and the locking hook 7 engages with the front locking tooth 122; as shown Figure 1 As shown, the latch 6 is held in place by the elastic restoring force of the latch spring 63, maintaining engagement with the rear latch tooth 121; the hook 7 is held in place by the elastic restoring force of the hook spring 73, maintaining engagement with the front latch tooth 122. This ensures a stable installation connection between the base assembly 1 and the hinge arm assembly 2. Figure 7 As shown, the second installation operation of the base assembly 1 and the hinge arm assembly 2 is as follows: the hinge arm assembly 2 and the base assembly 1 are tilted relative to each other (the front end of the hinge arm assembly 2 is relatively close to the inner wall of the cabinet, while the rear end of the hinge arm assembly 2 is relatively far away from the inner wall of the cabinet), and then the hinge arm assembly 2 is moved backward so that the front latch 122 is inserted into the locking hook 7. The locking buckle 6 is swung clockwise, and then the rear end of the hinge arm assembly 2 is swung towards the inner wall of the cabinet. When the position of the rear latch 121 corresponds to the locking buckle 6, the locking buckle 6 is released. The elastic restoring force of the locking spring 63 drives the locking buckle 6 to swing counterclockwise, so that the locking buckle 6 engages with the rear latch 121. As can be seen from the above, the quick-installation hinge structure of this utility model utilizes the locking spring 63 and the locking hook spring 73 to achieve a self-locking (clamping) action, thus making the installation process of the base assembly 1 and the hinge arm assembly 2 relatively quick. That is to say, the installation process of the cabinet door and the cabinet body is relatively quick. Moreover, due to the quick-installation hinge structure of this utility model, the front end of the hinge arm assembly 2 can be connected to the front end of the base assembly 1 first, or the rear end of the hinge arm assembly 2 can be connected to the rear end of the base assembly 1 first. Therefore, the installation operation of the hinge arm assembly 2 and the base assembly 1 is more flexible, which is more conducive to the flexible installation of the cabinet door.

[0031] Furthermore, such as Figure 9 As shown, the locking hook 7 has a front hook groove 71 for engaging the front buckle tooth 122, as... Figure 1 As shown, the specific engagement structure between the locking hook 7 and the front buckle tooth 122 is that the front hook groove 71 engages with the front buckle tooth 122, as shown. Figure 9As shown, the locking hook 7 has a hook outer edge 711 formed at the corresponding position of the front hook groove 71. Specifically, a hook portion 710 is formed on the outer side of the front hook groove 71. Therefore, the inner wall of the front hook groove 71 can be understood as the "hook inner edge", while the hook outer edge 711 is the outer edge of the hook portion 710. Figure 6 and Figure 10 As shown, a pushing edge 1222 is formed on one side of the front locking tooth 122 for pushing the outer edge 711 of the hook to allow the locking hook 7 to swing open. Figure 5 and Figure 6 As shown, during the first installation operation of the base assembly 1 and the hinge arm assembly 2, when the front end of the hinge arm assembly 2 is swung against the inner wall of the cabinet, as... Figure 6 As shown, the outer edge 711 of the hook will contact the pushing edge 1222, and the reaction force of the pushing edge 1222 on the outer edge 711 of the hook (such as...) Figure 6 (As shown by the dashed arrow in the image) A counterclockwise torque is generated about the swing axis of the hook 7, causing the hook 7 to swing counterclockwise and open. The outer edge 711 of the hook slides along the pushing edge 1222. During this process, the locking spring 73 of the hook further deforms elastically. When the front buckle 122 moves to the position aligned with the front hook groove 71, the elastic restoring force of the locking spring 73 drives the hook 7 to swing clockwise, so that the front buckle 122 automatically inserts into the front hook groove 71. In other words, it avoids the need for the user to manually (overcome the elastic restoring force of the locking spring 73) swing the hook 7 counterclockwise. Instead, after connecting the rear buckle 121 to the latch 6, the user can push the hinge arm assembly 2 in the left and right directions to make the pushing edge 1222 push open the hook 7, which facilitates the installation of the base assembly 1 and the hinge arm assembly 2. Figure 11 As shown, the latch 6 has a rear hook groove 61, as... Figure 1 As shown, specifically, the rear buckle tooth 121 engages with the rear hook groove 61, as... Figure 1 As shown, the rear hook groove 61 is designed to open forward, and the front hook groove 71 is designed to open backward.

[0032] Furthermore, such as Figure 10 As shown, the extrusion edge 1222 is a convex arc shape, as... Figure 6 As shown, during the process of connecting the locking hook 7 to the front latch tooth 122, the push edge 1222 swings approximately around the position of the rear latch tooth 121 relative to the hinge arm assembly 2. As a result, the push edge 1222 will slide and roll relative to the hook outer edge 711. Since the push edge 1222 is convex arc-shaped, it can better adapt to the swing of the push edge 1222 relative to the hook outer edge 711. Therefore, the frictional resistance of the push edge 1222 and the hook outer edge 711 rolling relative to each other is small, which can reduce the jamming situation. The hook outer edge 711 can be a rounded edge.

[0033] Furthermore, such as Figures 1 to 4As shown, the hinge arm assembly 2 includes a hinge arm 21 and an inner arm 22. The hinge arm 21 covers the outside of the inner arm 22. Both the hinge arm 21 and the inner arm 22 are slotted shell structures. Specifically, the front end of the hinge arm 21 is hinged to the hinge cup 3, and the locking hook 7 is hinged to the inner arm 22 through the locking hook hinge pin 70. That is to say, the locking hook hinge pin 70 extends in the vertical direction and is adapted to pass through the locking hook 7 and the inner arm 22. Figure 1 As shown, the latch 6 is specifically hinged to the inner arm 22 via the latch hinge pin 60. (As...) Figure 9 As shown, a limiting protrusion 72 is formed on the locking hook 7, such as Figure 4 As shown, the limiting protrusion 72 and the front hook groove 71 are located on both sides of the locking hook hinge pin 70, as... Figure 8 As shown, the inner arm 22 has an inner arm top plate 221 and an inner arm side plate 222. The upper and lower ends of the inner arm top plate 221 are integrally connected to the corresponding inner arm side plates 222, as shown. Figure 2 and Figure 4 As shown, the locking hook 7 is located between the upper and lower inner arm side plates 222, as... Figure 4 As shown, the limiting protrusion 72 can abut against the inner arm top plate 221 through the elastic restoring force of the locking spring 73. As mentioned above, the elastic restoring force of the locking spring 73 can drive the locking hook 7 to swing clockwise. As the locking hook 7 swings clockwise, when the limiting protrusion 72 moves to abut against the inner arm top plate 221, the inner arm top plate 221 prevents the locking hook 7 from swinging further clockwise. Figure 4 As shown, the locking hook 7 can be stopped at a certain angle relative to the inner arm 22, thus, as Figure 5 and Figure 6 As shown, when the locking hook 7 swings approximately around the rear latching tooth 121 and moves towards the front latching tooth 122, the contact position between the hook outer edge 711 and the pushing edge 1222 becomes more stable, which makes it easier for the pushing edge 1222 to push open the hook outer edge 711 and facilitates the stable installation of the hinge arm assembly 2 and the base assembly 1.

[0034] Furthermore, such as Figure 8 As shown, the inner arm side plate 222 includes a baffle portion 2221, as... Figure 1 Combination Figure 4 As shown, the baffle portion 2221 abuts against the outer side of the front buckle tooth 122 and the locking hook 7. This means that when the front buckle tooth 122 moves up and down relative to the inner arm 22, it is blocked by the baffle portion 2221, thus preventing misalignment between the front buckle tooth 122 and the front hook groove 71, which is beneficial for a stable connection between the locking hook 7 and the base assembly 1. Furthermore, as... Figure 5 and Figure 6As shown, during the connection between the locking hook 7 and the front buckle 122, when the pushing edge 1222 contacts the outer edge 711 of the hook, the front buckle 122 is already against the inner side of the corresponding inner arm side plate 222. The inner arm side plate 222 then guides the relative movement of the front buckle 122 and the locking hook 7, which is beneficial to the stable installation of the base assembly 1 and the hinge arm assembly 2.

[0035] Furthermore, such as Figure 2 , Figure 4 and Figure 5 As shown, the locking spring 73 on the hook is a torsion spring, which is sleeved on the hook hinge pin 70. One end of the locking spring 73 is connected to the hook 7, and the other end of the locking spring 73 is connected to the inner arm 22. Compared with setting the locking spring 73 as a compression spring or a tension spring, setting the locking spring 73 as a torsion spring allows the locking spring 73 to be sleeved on the hook hinge pin 70, which helps to make the combined structure of the locking spring 73 and the hook hinge pin 70 occupy less space.

[0036] Furthermore, such as Figure 10 As shown, the base assembly 1 has a positioning groove 123, and the inner arm 22 is provided with a positioning shaft 223, which extends in the vertical direction, as shown. Figure 8 As shown, a positioning shaft mounting hole 2201 is formed on the inner arm 22, and a positioning shaft 223 passes through the positioning shaft mounting hole 2201. The two ends of the positioning shaft 223 are riveted to the edges of the positioning shaft mounting hole 2201. Figure 1 As shown, the positioning shaft 223 is adapted to be disposed within the positioning groove 123, thus preventing the inner arm 22 from shifting relative to the base assembly 1. When the base assembly 1 and the hinge arm assembly 2 are installed, during the swinging process of the hinge arm assembly 2 relative to the base assembly 1, the positioning shaft 223 swings into the positioning groove 123.

[0037] Furthermore, such as Figure 2 and Figure 3 As shown, the base assembly 1 includes an adjustable height seat 12 and a mounting base 11 for mounting and connecting the cabinet. The bottom of the mounting base 11 has two screw mounting holes 1101 (front and back). Self-tapping screws can pass through the screw mounting holes 1101 and be screwed onto the cabinet. The adjustable height seat 12 is located inside the mounting base 11. The mounting base 11 is provided with a sliding guide pin 101, which adapts to pass through the adjustable height seat 12. The adjustable height seat 12 can slide slightly up and down within the mounting base 11. Figure 10 As shown, the rear retaining tooth 121 is specifically formed at the rear end of the upper and lower adjusting seat 12, the front retaining tooth 122 is specifically formed at the front end of the upper and lower adjusting seat 12, and the positioning groove 123 is specifically formed at the top of the upper and lower adjusting seat 12. Figure 1 and Figure 3As shown, the bottom of the mounting base 11 is rotatably connected to an eccentric adjusting pin 13. The eccentric part of the eccentric adjusting pin 13 is located inside the adjusting seat 12. Rotating the eccentric adjusting pin 13 causes the eccentric part of the eccentric adjusting pin 13 to push the adjusting seat 12. Since the adjusting seat 12 is adapted to fit within the inner arm 22 in the vertical direction, the inner arm 22 and the adjusting seat 12 can move up and down together for adjustment. Because the hinge arm 21 covers the outside of the inner arm 22, and the inner wall of the hinge arm 21 is against the outer wall of the inner arm 22, the hinge arm 21 cannot move up and down relative to the inner arm 22. Therefore, rotating the eccentric adjusting pin 13 can adjust the cabinet door up and down. Figure 1 and Figure 2 As shown, the hinge arm 21 is rotatably connected to a front-to-back adjusting eccentric pin 5. The eccentric part of the front-to-back adjusting eccentric pin 5 is located in an elongated hole extending vertically on the inner arm 22. Therefore, rotating the front-to-back adjusting eccentric pin 5 allows the hinge arm 21 to move back and forth relative to the inner arm 22 for adjustment. Figure 1 and Figure 2 As shown, the hinge arm 21 is screwed with a left-right adjusting pin 4. One end of the left-right adjusting pin 4 is slidably engaged with the inner arm 22. Therefore, rotating the left-right adjusting pin 4 allows the hinge arm 21 and the inner arm 22 to move and adjust relative to each other in a small range in the left-right direction. Figure 2 As shown, the bottom of the mounting base 11 has a guide V-shaped groove 1102 extending in the vertical direction, as... Figure 10 As shown, the upper and lower adjusting seat 12 has a sliding tooth 124, which is triangular in shape, as shown in the figure. Figure 2 and Figure 3 As shown, the sliding tooth 124 is adapted to slide within the guide V-groove 1102, so the guide V-groove 1102 plays a sliding guiding role for the upper and lower adjusting seat 12.

[0038] Furthermore, such as Figure 1 and Figure 11 As shown, an unlocking handle 62 is formed at the rear end of the latch 6. The unlocking handle 62 protrudes rearward from the hinge arm assembly 2, as shown. Figure 7As shown, when performing the second installation operation of the base assembly 1 and the hinge arm assembly 2, the user can use their finger to hook and pull the unlocking handle 62 to make the unlocking handle 62 swing open in the clockwise direction. Then, the rear end of the hinge arm assembly 2 can be swung approximately around the position of the front latch 122 and moved towards the inner wall of the cabinet, making the operation more convenient. Moreover, when it is necessary to disassemble the base assembly 1 and the hinge arm assembly 2, first use your finger to hook and pull the unlocking handle 62 to make the unlocking handle 62 swing open in the clockwise direction. Then, swing the rear end of the hinge arm assembly 2 away from the inner wall of the cabinet, that is, make the rear latch 121 disengage from the latch 6. Then, pull the hinge arm assembly 2 forward to make the front latch 122 disengage from the front hook groove 71. During the disassembly process of the hinge arm assembly 2 and the base assembly 1, the locking hook 7 can swing and shift slightly around the locking hook hinge pin 70 with the movement of the hinge arm assembly 2, which can reduce the jamming situation encountered when disassembling the hinge arm assembly 2. Figure 1 As shown, the locking spring 63 is located between the inner arm top plate 221 and the unlocking handle 62, and the locking spring 63 is a compression spring.

[0039] Furthermore, such as Figure 11 As shown, anti-slip teeth 621 are formed on the unlocking handle 62. When the finger hooks the unlocking handle 62, the anti-slip teeth 621 contact the finger, which can prevent the finger from slipping easily.
