Detailed implementation

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

[0029] The hinge quick installation structure of the present invention, as Figures 1 to 4 shown, includes a base assembly 1 and a hinge arm assembly 2. The base assembly 1 is used for installing and connecting the cabinet body, and the hinge arm assembly 2 is used for hinging the hinge cup 3. The hinge cup 3 is used for installing on the back of the cabinet door. A lock 6 is hinged at the rear part of the hinge arm assembly 2, so that the lock 6 can swing relative to the hinge arm assembly 2. A lock hook 7 is hinged at the front part of the hinge arm assembly 2, so that the lock hook 7 can swing relative to the hinge arm assembly 2. A rear locking tooth 121 is provided at the rear end of the base assembly 1, and a front locking tooth 122 is provided at the front end of the base assembly 1. As Figure 1 shown, when the base assembly 1 and the hinge arm assembly 2 are in a connected state, that is, when the hinge is in use, the lock 6 is clamped to the rear locking tooth 121, and the lock hook 7 is clamped to the front locking tooth 122. As Figure 1 shown, the lock 6 is connected with a lock upper spring 63 for driving the lock 6 to swing. In other words, the lock upper spring 63 can drive the lock 6 to swing counterclockwise to lock and connect the rear locking tooth 121. The lock hook 7 is connected with a lock hook upper spring 73 for driving the lock hook 7 to swing. In other words, the lock hook upper spring 73 can drive the lock hook 7 to swing clockwise to lock and connect the front locking tooth 122.

[0030] As Figure 3 and Figure 4 shown, the base assembly 1 and the hinge arm assembly 2 can be detachably separated. As Figure 5As shown in the figure, the first installation operation of the base assembly 1 and the articulated arm assembly 2: First, the base assembly 1 can be installed on the inner wall of the cabinet door through self-tapping screws, and the hinge cup 3 is installed on the back of the cabinet door. Then, the articulated arm assembly 2 is tilted relative to the base assembly 1, and the rear end of the articulated arm assembly 2 is leaned against the inner wall of the cabinet. At this time, the lock 6 is located behind the rear engaging tooth 121. Then, the articulated arm assembly 2 is moved forward, so that the rear engaging tooth 121 is relatively inserted into the lock 6, that is to say, the lock 6 is clamped with the rear engaging tooth 121. Then, the lock hook 7 swings counterclockwise (the lock hook locking spring 73 is further elastically deformed), and then the front end of the articulated arm assembly 2 is swung and leaned against the inner wall of the cabinet, and the lock hook 7 is released. The elastic restoring force of the lock hook locking spring 73 drives the lock hook 7 to swing clockwise. Thus, as Figure 1 shown, the lock hook 7 is buckled on the front engaging tooth 122, that is to say, the front engaging tooth 122 is relatively inserted into the lock hook 7, that is to say, the lock hook 7 is clamped with the front engaging tooth 122; as Figure 1 shown, the lock 6 is kept clamped with the rear engaging tooth 121 by the elastic restoring force of the lock locking spring 63, and the lock hook 7 is kept clamped with the front engaging tooth 122 by the elastic restoring force of the lock hook locking spring 73, so that the base assembly 1 and the articulated arm assembly 2 can maintain a stable installation connection state. As Figure 7 shown, the second installation operation of the base assembly 1 and the articulated arm assembly 2: The articulated arm assembly 2 is tilted relative to the base assembly 1 (the front end of the articulated arm assembly 2 is relatively close to the inner wall of the cabinet, and the rear end of the articulated arm assembly 2 is relatively far from the inner wall of the cabinet). Then, the articulated arm assembly 2 is moved backward, so that the front engaging tooth 122 is relatively inserted into the lock hook 7, the lock 6 is swung clockwise, and then the rear end of the articulated arm assembly 2 is swung and leaned against the inner wall of the cabinet. When the rear engaging tooth 121 is in position corresponding to the lock 6, the lock 6 is released, and the elastic restoring force of the lock locking spring 63 drives the lock 6 to swing counterclockwise, so that the lock 6 is clamped with the rear engaging tooth 121. As can be seen from the above, the hinge quick installation structure of the present invention uses the lock locking spring 63 and the lock hook locking spring 73 to realize the self-locking (clamping) action, so that the installation process of the base assembly 1 and the articulated arm assembly 2 is relatively fast, that is to say, the installation process of the cabinet door and the cabinet body is relatively fast. Moreover, due to the hinge quick installation structure of the present invention, the front end of the articulated arm assembly 2 and the front end of the base assembly 1 can be connected first, or the rear end of the articulated arm assembly 2 and the rear end of the base assembly 1 can be connected first. Thus, the installation operation of the articulated arm assembly 2 and the base assembly 1 is relatively flexible, so it is more conducive to the flexible installation of the cabinet door.

[0031] Furthermore, as Figure 9 shown, the lock hook 7 is formed with a front hook groove 71 for clamping the front engaging tooth 122. As Figure 1 shown, that is to say, the clamping structure between the lock hook 7 and the front engaging tooth 122 is specifically that the front hook groove 71 is clamped with the front engaging tooth 122. As Figure 9As shown, a hook outer edge 711 is formed at a position corresponding to the front hook groove 71 of the locking hook 7. Specifically, a hook portion 710 is formed on the outer side of the front hook groove 71. Thus, the inner wall of the front hook groove 71 can be understood as the "hook inner edge", and the hook outer edge 711 is the outer edge of the hook portion 710. As Figure 6 and Figure 10 shown, a pushing edge 1222 is formed on one side of the front locking tooth 122 for pushing the hook outer edge 711 to swing the locking hook 7 open. As Figure 5 and Figure 6 shown, during the first installation operation of the above-mentioned base assembly 1 and the articulated arm assembly 2, when the front end of the articulated arm assembly 2 is swung towards the inner wall of the cabinet, as Figure 6 shown, the hook outer edge 711 will contact the pushing edge 1222. The reaction force of the pushing edge 1222 on the hook outer edge 711 (as Figure 6 shown by the dotted arrow in) forms a counterclockwise moment about the swing axis of the locking hook 7, so that the locking hook 7 swings counterclockwise to open. The hook outer edge 711 slides along the pushing edge 1222. During this period, the locking spring 73 of the locking hook is further elastically deformed. When the front locking tooth 122 moves relatively to align with the front hook groove 71, the elastic restoring force of the locking spring 73 of the locking hook drives the locking hook 7 to swing clockwise, so that the front locking tooth 122 is inserted into the front hook groove 71 by itself relatively. In other words, it can avoid the need for the user to swing the locking hook 7 counterclockwise by hand (overcoming the elastic restoring force of the locking spring 73 of the locking hook). Instead, after the user connects the rear locking tooth 121 to the lock catch 6, by pushing and pressing the articulated arm assembly 2 in the left-right direction, the pushing edge 1222 can push open the locking hook 7, which is beneficial to the more convenient installation of the base assembly 1 and the articulated arm assembly 2. As Figure 11 shown, the lock catch 6 is formed with a rear hook groove 61. As Figure 1 shown, specifically, the rear locking tooth 121 is clamped in the rear hook groove 61. As Figure 1 shown, the rear hook groove 61 is arranged with an opening forward, and the front hook groove 71 is arranged with an opening backward.

[0032] Furthermore, as Figure 10 shown, the pushing edge 1222 is convex arc-shaped. As Figure 6 shown, during the process of connecting the locking hook 7 and the front locking tooth 122, the pushing edge 1222 swings relative to the articulated arm assembly 2 approximately around the position of the rear locking tooth 121. Thus, the pushing edge 1222 will slide and roll relative to the hook outer edge 711. Since the pushing edge 1222 is convex arc-shaped, it can better adapt to the swing of the pushing edge 1222 relative to the hook outer edge 711. Thus, the frictional resistance of the relative rolling between the pushing edge 1222 and the hook outer edge 711 is smaller, which can reduce the jamming situation. The hook outer edge 711 can be an arc edge.

[0033] Furthermore, as Figures 1 to 4As shown, the articulated 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 in the shape of a grooved shell. 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 a locking hook hinge pin 70. That is to say, the locking hook hinge pin 70 extends in the up and down direction, and the locking hook hinge pin 70 is adapted to pass through the locking hook 7 and the inner arm 22. As Figure 1 shown, the latch 6 is specifically hinged to the inner arm 22 through a latch hinge pin 60. As Figure 9 shown, a limiting convex portion 72 is formed on the locking hook 7. As Figure 4 shown, the limiting convex portion 72 and the front hook groove 71 are respectively located on both sides of the locking hook hinge pin 70. As Figure 8 shown, the inner arm 22 is formed with an inner arm top plate 221 and inner arm side plates 222. The upper and lower ends of the inner arm top plate 221 are integrally connected to the corresponding inner arm side plates 222 respectively. As Figure 2 and Figure 4 shown, the locking hook 7 is arranged between the upper and lower inner arm side plates 222. As Figure 4 shown, the limiting convex portion 72 can be attached to and connected to the inner arm top plate 221 by the elastic restoring force of the locking hook upper spring 73. As mentioned above, the elastic restoring force of the locking hook upper spring 73 can drive the locking hook 7 to swing clockwise. As the locking hook 7 swings clockwise, when the limiting convex portion 72 moves to abut against the inner arm top plate 221, the inner arm top plate 221 blocks the further clockwise swing of the locking hook 7. As Figure 4 shown, the locking hook 7 can be made to stop at a certain angular position relative to the inner arm 22. Thus, as Figure 5 and Figure 6 shown, when the locking hook 7 swings around the position of the rear latching tooth 121 and approaches the front latching tooth 122, the position where the outer hook edge 711 contacts the pushing edge 1222 is relatively stable, which is beneficial to the pushing edge 1222 to easily push open the outer hook edge 711 and is beneficial to the stable installation of the articulated arm assembly 2 and the base assembly 1.

[0034] Further, as Figure 8 shown, the inner arm side plate 222 includes a baffle portion 2221. As Figure 1 Combined with Figure 4 shown, the baffle portion 2221 abuts against the outside of the front latching tooth 122 and the locking hook 7. That is to say, when the front latching tooth 122 moves up and down relative to the inner arm 22, it will be blocked by the baffle portion 2221, which can prevent the front latching tooth 122 from being vertically displaced from the front hook groove 71 and is beneficial to the stable connection between the locking hook 7 and the base assembly 1. And, as Figure 5 and Figure 6As shown, during the connection of the locking hook 7 and the front engaging tooth 122, when the pushing edge 1222 contacts the outer hook edge 711, the front engaging tooth 122 has already abutted against the inner side of the corresponding inner arm side plate 222, and the inner arm side plate 222 guides the relative movement between the front engaging tooth 122 and the locking hook 7, thus facilitating the stable installation of the base assembly 1 and the articulated arm assembly 2.

[0035] Furthermore, as Figure 2 , Figure 4 and Figure 5 shown, the upper locking spring 73 of the locking hook is set as a torsion spring. The upper locking spring 73 of the locking hook is sleeved on the locking hook hinge pin 70. One end of the upper locking spring 73 of the locking hook is connected to the locking hook 7, and the other corresponding end of the upper locking spring 73 of the locking hook is connected to the inner arm 22. Compared with setting the upper locking spring 73 of the locking hook as a compression spring or a tension spring, setting the upper locking spring 73 of the locking hook as a torsion spring enables the upper locking spring 73 of the locking hook to be sleeved on the locking hook hinge pin 70, thus facilitating a smaller occupied space for the combined structure of the upper locking spring 73 of the locking hook and the locking hook hinge pin 70.

[0036] Furthermore, as Figure 10 shown, the base assembly 1 is formed with a positioning groove 123, and the inner arm 22 is provided with a positioning shaft 223. The positioning shaft 223 extends in the up and down direction. As Figure 8 shown, a positioning shaft mounting hole 2201 is formed on the inner arm 22. The positioning shaft 223 passes through the positioning shaft mounting hole 2201, and both ends of the positioning shaft 223 are riveted to the edge part of the positioning shaft mounting hole 2201 correspondingly. As Figure 1 shown, the positioning shaft 223 is adaptively arranged in the positioning groove 123, thus preventing the relative front and back displacement between the inner arm 22 and the base assembly 1. When installing the base assembly 1 and the articulated arm assembly 2, during the swinging of the articulated arm assembly 2 relative to the base assembly 1, the positioning shaft 223 swings into the positioning groove 123.

[0037] Furthermore, as Figure 2 and Figure 3 shown, the base assembly 1 includes an up and down adjustment seat 12 and a mounting seat 11 for installing and connecting the cabinet body. Two screw mounting holes 1101 in total, front and back, are formed at the bottom of the mounting seat 11. The self-tapping screw can pass through the screw mounting hole 1101 and be screwed with the cabinet body. The up and down adjustment seat 12 is arranged in the mounting seat 11. A sliding guide pin 101 is provided on the mounting seat 11. The sliding guide pin 101 is adaptively passed through the up and down adjustment seat 12, and the up and down adjustment seat 12 can slide slightly up and down in the mounting seat 11. As Figure 10 shown, the rear engaging tooth 121 is specifically formed at the rear end of the up and down adjustment seat 12, the front engaging tooth 122 is specifically formed at the front end of the up and down adjustment seat 12, and the positioning groove 123 is specifically formed at the top of the up and down adjustment seat 12. As Figure 1 and Figure 3As shown in the figure, a vertically adjustable eccentric pin 13 is rotatably connected to the bottom of the mounting seat 11. The eccentric part of the vertically adjustable eccentric pin 13 is arranged inside the vertically adjustable seat 12. Therefore, by rotating the vertically adjustable eccentric pin 13, the eccentric part of the vertically adjustable eccentric pin 13 can push the vertically adjustable seat 12. Since the vertically adjustable seat 12 is adaptively arranged inside the inner arm 22 in the vertical direction, the inner arm 22 and the vertically adjustable seat 12 can be moved up and down together for adjustment. Since the hinge arm 21 covers the outside of the inner arm 22 and the inner wall of the hinge arm 21 abuts against the outer wall of the inner arm 22, the hinge arm 21 cannot be displaced up and down relative to the inner arm 22. Therefore, rotating the vertically adjustable eccentric pin 13 can adjust the vertical position of the cabinet door; As Figure 1 and Figure 2 shown in the figure, a front-back adjustable eccentric pin 5 is rotatably connected to the hinge arm 21. The eccentric part of the front-back adjustable eccentric pin 5 is arranged in a long hole extending in the vertical direction on the inner arm 22. Therefore, rotating the front-back adjustable eccentric pin 5 can make the hinge arm 21 move back and forth relative to the inner arm 22 for adjustment; As Figure 1 and Figure 2 shown in the figure, a left-right adjustable screw 4 is screwed to the hinge arm 21. One end of the left-right adjustable screw 4 is slidably clamped to the inner arm 22. Therefore, rotating the left-right adjustable screw 4 can make the hinge arm 21 and the inner arm 22 move slightly relative to each other in the left-right direction for adjustment. As Figure 2 shown in the figure, a guiding V-shaped groove 1102 extending in the vertical direction is formed at the bottom of the mounting seat 11, as Figure 10 shown in the figure, the vertically adjustable seat 12 is formed with sliding teeth 124, and the sliding teeth 124 are triangular, as Figure 2 and Figure 3 shown in the figure, the sliding teeth 124 are adaptively and slidably arranged in the guiding V-shaped groove 1102. Therefore, the guiding V-shaped groove 1102 plays a role in sliding guidance for the vertically adjustable seat 12.

[0038] Furthermore, as Figure 1 and Figure 11 shown in the figure, an unlocking handle 62 is formed at the rear end of the lock catch 6, and the unlocking handle 62 protrudes backward from the hinge arm assembly 2, as Figure 7As shown in the figure, when the base assembly 1 and the articulated arm assembly 2 perform the above-mentioned second installation operation, the user can hook the unlocking handle 62 with a finger to swing the unlocking handle 62 clockwise to open it, and then swing the rear end of the articulated arm assembly 2 around the position of the front locking tooth 122 and lean it against the inner wall of the cabinet. The operation is relatively convenient. Moreover, when it is necessary to disassemble and separate the base assembly 1 and the articulated arm assembly 2, first hook the unlocking handle 62 with a finger to swing the unlocking handle 62 clockwise to open it, and then swing the rear end of the articulated arm assembly 2 away from the inner wall of the cabinet, that is, make the rear locking tooth 121 relatively disengage from the lock catch 6, and then pull the articulated arm assembly 2 forward to make the front locking tooth 122 relatively disengage from the front hook groove 71. During the disassembly process of the articulated arm assembly 2 and the base assembly 1, the lock hook 7 can swing and shift slightly around the lock hook hinge pin 70 correspondingly with the movement of the articulated arm assembly 2, which can reduce the jamming situation encountered during the disassembly of the articulated arm assembly 2. As Figure 1 shown, the lock catch locking spring 63 is arranged between the inner arm top plate 221 and the unlocking handle 62, and the lock catch locking spring 63 is a compression spring.

[0039] Furthermore, as Figure 11 shown, anti-slip teeth 621 are formed on the unlocking handle 62. Therefore, when the unlocking handle 62 is hooked by a finger, the anti-slip teeth 621 contact the finger, which can prevent the finger from slipping easily.
