So set, by the axial rotation adjusting screw 7, movable part 25 can adjust the angle of first branch 31 or second branch 32 in the accommodation groove relative to the cover plate, avoid the cantilever between hinge arm 3 and the cover plate, guarantee the gravity center of hinge arm 3 to be located in the accommodation groove, avoid the increase of torque, even if long -term use, will not occur the connection slack, deviation and fall off between hinge arm 3 and cabinet body, greatly prolongs the service life.
[0052] Specifically, define the branch arm hinged with hinge cup 1 as first branch 31, and the branch arm connected with base 2 as second branch 32, define the cover plate with movable part 25 as second cover plate 22, and the other cover plate as first cover plate 21, as shown in Figure 2 , Figure 3 In the embodiment, the first cover plate 21 is provided with a notch, and the notch is provided with a pair of extended side walls in the direction towards the second cover plate 22, i.e. in the direction opposite to the direction indicated by the arrow Z, the planes where the two side walls are located are respectively perpendicular to the direction indicated by the arrow X, and the half-enclosed space formed by the two side walls and the second cover plate 22 is the accommodation groove in the embodiment, and the second branch 32 can move in the accommodation groove. Figure 3
[0053] Please refer to Figure 4 , Figure 4 As a perspective view of the second arm 32 in the embodiment, the second arm 32 comprises a bending part 321 and a plug-in part 322, the bending part 321 is used for hinged connection with the first arm 31, and when the door body is closed relative to the cabinet body, i.e. when the hinged cup 1 is retracted relative to the base 2, the bending part 321 plays a role of limiting the hinged cup 1; the plug-in part 322 is used for plugging into the accommodating groove and connecting with the base 2. The aforementioned adjusting screw 7 penetrates through the fifth through hole 323 on the plug-in part 322, the fifth through hole 323 is configured as a threaded hole, the adjusting screw 7 is screwed with the fifth through hole 323, and is positioned Figure 3 The adjusting screw 7 can move in the sliding groove 23 along the direction indicated by the Y arrow, the direction indicated by the Y arrow is defined as a first direction, the second arm 32 is plugged into the accommodating groove along the first direction, the direction indicated by the X arrow is defined as a second direction, and the direction indicated by the Z arrow is defined as a third direction, the first direction, the second direction and the third direction are perpendicular to each other. The modular adjustable hinge in the embodiment further comprises a first adjusting pin 5, the first adjusting pin 5 is sequentially provided in the seventh through hole 325 on the second arm 32 and the first positioning hole 251 on the movable part 25, and is riveted with the first positioning hole 251; specifically, the movable part 25 in the embodiment is configured as a movable sheet, the movable sheet is integrally formed with the second cover plate 22, and a semi-encircling truncated notch is arranged between the movable sheet and the second cover plate 22, i.e. the movable sheet can move relative to the second cover plate 22 in the third direction. The first adjusting pin 5 in the embodiment is configured as an eccentric pin, when the first adjusting pin 5 is axially rotated, the second arm 32 can move in the accommodating groove along the first direction, and in the process of moving of the second arm 32, the adjusting screw 7 can slide in the sliding groove 23, since the adjusting screw 7 abuts against the side wall of the sliding groove 23, it can play a role of maintaining the movement stability of the second arm 32, so that the second arm 32 moves under the limiting action of the side wall of the first cover plate 21 gap and the side wall of the sliding groove 23, and the first adjusting pin 5 can adjust the position of the end of the second arm 32 in the accommodating groove.
[0054] Specifically, please refer to Figure 8 and Figure 9 , Figure 8 and Figure 9 are two limit positions of the second arm 32 moving in the first direction in the accommodating groove, Figure 8 the end of the second arm 32 abuts against the side wall of the accommodating groove of the base 2 in the first direction, Figure 9 the end of the second arm 32 is away from the side wall of the accommodating groove in the first direction, by rotating the first adjusting pin 5 clockwise or counterclockwise, the relative position of the second arm 32 in the first direction can be adjusted, which is equivalent to adjusting the position of the hinged arm 3 relative to the base 2 in the second direction, so as to adjust the size of the gap between the door body and the cabinet body when the door body is installed, and achieve the best alignment effect.
[0055] It should be noted that the eccentric pin is a special bolt with eccentric structure, the axis of the threaded shaft does not coincide with the geometric center of the nut, but has a certain offset relative to the geometric center of the nut. When the eccentric pin rotates, the threaded shaft is limited to rotate in the threaded hole, and the nut rotates with the threaded shaft with offset, thereby pushing the structure abutting with the nut to move to realize the displacement and adjustment function.
[0056] Further, since the adjusting screw 7 is screwed with the fifth through hole 323 on the second branch arm 32, when the adjusting screw 7 is axially rotated, the engagement position of the adjusting screw 7 and the thread of the fifth through hole 323 changes, and the relative position of the second branch arm 32 and the second cover plate 22 in the Z direction can be adjusted; at the same time, the end of the second branch arm 32 away from the fifth through hole 323, specifically at the seventh through hole 325 of the second branch arm 32, since the first adjusting pin 5 is riveted with the movable piece, the movable piece has the freedom of movement in the Z direction relative to the second cover plate 22 under the action of its own elastic stress, so that when the adjusting screw 7 adjusts the position of the fifth through hole 323 in the Z direction, the position of the movable piece in the Z direction can be adaptively adjusted, realizing the angle adjustment of the second branch arm 32 relative to the second cover plate 22. It can be understood that, by axially rotating the adjusting screw 7, the angle of the second branch arm 32 around the axis in the X direction can be adjusted; this setting method using the elastic stress of the movable piece instead of adding a movable shaft not only reduces the assembly difficulty, but also can compress the production cost, facilitating mass production. More preferably, as shown in Figure 7 , compared with the state diagram of the second branch arm 32 in Figure 1 , Figure 7 , when the adjusting screw 7 is axially rotated, the second branch arm 32 moves to the limit position that it can move in the Z direction, that is, when the adjusting screw 7 adjusts the second branch arm 32 to rotate to the maximum angle formed by the second branch arm 32 relative to the second cover plate 22, the second branch arm 32 will not be separated from the containing groove, and the highest point of the movement of the second branch arm 32 in the Z direction will not be higher than the plane where the first cover plate 21 is located. In this way, the side wall of the gap of the first cover plate 21 can always be clamped in the X direction to the second branch arm 32, avoiding the cantilever between the hinge arm 3 and the cover plate, ensuring that the center of gravity of the hinge arm 3 is located in the containing groove, avoiding the increase of torque, even if used for a long time, the connection between the hinge arm 3 and the cabinet body will not be loose, offset and fall off, greatly prolonging the service life.
[0057] As an optional embodiment, please refer to Figure 2The third branch 33 is hingedly connected to one end of the second branch 32 and to the other end of the hinge cup 1, so as to enhance the stability of the connection between the hinge cup 1 and the second branch 32.
[0058] Further, referring to Figure 5 The modular adjustable hinge further comprises a chassis 4, both ends of the chassis 4 along the Y direction are respectively provided with a pair of sliding blocks, for the sake of distinction, the two pairs of sliding blocks are defined as a first sliding block 41 and a second sliding block 42, the cross sections of the first sliding block 41 and the second sliding block 42 along the X direction are both configured as concave shapes, used for clamping connection to the second cover plate 22 of the base 2 and capable of sliding relative to the second cover plate 22, the chassis 4 is provided with a second positioning hole 43, in combination with Figure 3 The first cover plate 21 is provided with a through slot 26, the through slot 26 can expose a plurality of through holes on the second cover plate 22 in the Z direction, a second adjusting pin 6 is arranged at the second through hole 27, the second adjusting pin 6 is sequentially arranged through the second through hole 27 and the second positioning hole 43 and is riveted with the second positioning hole 43, the second adjusting pin 6 is similar to the first adjusting pin 5 and is configured as an eccentric pin, when the second adjusting pin 6 is axially rotated, the position of the chassis 4 relative to the second cover plate 22 in the X direction can be adjusted, as shown in Figure 7 Figure 7 The first sliding block 41 on one side of the chassis 4 moves to abut against the base 2 in the X direction and reaches the limit position, and it can be known in the same way that the first sliding block 41 on the other side can also move to abut against the base 2 on the other end, that is, the chassis 4 can move in the position interval of the base 2 on both ends in the X direction, in this way, the door body can move relative to the cabinet body in the first direction, so as to compensate for the error generated during installation, so that the door body and the cabinet body reach the best alignment state and ensure the smoothness and sealing performance of opening and closing.
[0059] Preferably, since the first adjusting pin 5 and the second adjusting pin 6 are both configured as eccentric pins, in order to avoid motion interference, the seventh through hole 325 and the second through hole 27 for arranging the first adjusting pin 5 and the second adjusting pin 6 are both configured as waist-shaped holes.
[0060] In this embodiment, the first adjusting pin 5 and the adjusting screw 7 are arranged on the plug-in part 322 of the second branch 32, the second adjusting pin 6 is arranged on the second cover plate 22 of the base 2, and the second adjusting pin 6 is located in the through slot 26 opened on the first cover plate 21, so that the adjustment of the modular adjustable hinge by the operator is more simplified and intuitive, and the probability of incorrect adjustment is reduced. The operator can operate these mechanisms in sequence along the second direction, so as to adjust the positional relationship between different components, reduce the complexity of adjustment, and avoid the interference problem that may occur during multi-direction and multi-point adjustment.
[0061] The adjusting screw 7, the first adjusting screw 5 and the second adjusting screw 6 can be used to adjust the relative displacement of the modular adjustable hinge in three directions of the three-dimensional space, so that the end face can be as flat as possible after installation, and the gap is small, the appearance is beautiful, and the service life of the modular adjustable hinge is prolonged.
[0062] As an optional embodiment, the modular adjustable hinge can include a damping assembly (not shown in the figure) installed in the hinge cup 1 to provide damping force when the hinge arm 3 rotates relative to the hinge cup 1, prevent the impact force from being too large when the hinge arm and the hinge cup are directly closed, affect the connection tightness, and then affect the service life. The setting of the damping assembly can effectively prolong the service life.
[0063] It can be understood that, in order to enhance the connection stability of the modular adjustable hinge of the embodiment and the door body and the cabinet body, please refer to Figure 3 to Figure 5 , the second cover plate 22 is provided with a first through hole 24, the second branch arm 32 is provided with a sixth through hole 324, the first through hole 24 and the sixth through hole 324 are communicated, and the corresponding position on the bottom disc 4 is also provided with a through hole for screwing, and the screw is sequentially screwed into the hinge arm 3, the base 2 and the bottom disc 4, thereby enhancing the connection strength; The second cover plate 22 is also provided with a third through hole 28 and a fourth through hole 29, the third through hole 28 and the fourth through hole 29 are arranged in pairs and are arranged at both ends of the second through hole 27 in the X direction, and the positions corresponding to the third through hole 28 and the fourth through hole 29 on the bottom disc 4 are provided with through holes for screwing; Preferably, since the hinge arm 3 in the embodiment can relatively displace in three directions of the three-dimensional space relative to the base 2, in order to improve the assembly adaptability, the first through hole 24, the third through hole 28 and the fourth through hole 29 are all configured as rectangles, of course, they can also be other shapes, as long as they can ensure that they have relative movement intervals in the X direction and the Y direction, respectively, and leave enough space for the screw installed in the cabinet.
[0064] Embodiment two
[0065] This embodiment is another embodiment different from embodiment one, and the repeated parts will not be described here.
[0066] Specifically, please refer to Figure 6 , Figure 6is a perspective exploded view of the second arm 32 in this embodiment. The movable part 25 in this embodiment is configured as a fixed block 3222, which is provided with a seventh through hole 325 for passing the first adjusting peg 5 therethrough. Compared with the first embodiment, the second arm 32 in this embodiment is shorter and is provided with only two through holes, i.e., a fifth through hole 323 and a sixth through hole 324. The fifth through hole 323 is configured as a threaded hole for passing and threadedly connecting the adjusting screw 7. Of course, the second arm 32 in this embodiment can also be regarded as the second arm 32 in the first embodiment being disassembled into the fixed block 3222 and a rotating block 3221. The fixed block 3222 is provided at one end with a first shaft hole 326, and the rotating block 3221 is provided at one end with a second shaft hole 327. A connecting pin shaft 3223 penetrates the first shaft hole 326 and the second shaft hole 327, so that the fixed block 3222 and the rotating block 3221 can relatively rotate about the connecting pin shaft 3223. The fixed block 3222 is provided at both ends along the X direction with rectangular protrusions, and the corresponding positions on the side wall of the first cover plate 21 extending toward the second cover plate 22 are provided with limiting grooves. The rectangular protrusions can be slidably inserted into the limiting grooves, thereby realizing the relative fixing of the position of the fixed block 3222 and the base 2 in the Z direction. The adjusting screw 7 is axially rotated, and the rotating block 3221 is rotated about the connecting pin shaft 3223 relative to the fixed block 3222 due to the change in the engagement position of the thread of the adjusting screw 7 and the fifth through hole 323, thereby adjusting the relative position of the second arm 32 and the second cover plate 22 in the Z direction.
[0067] In summary, the modular adjustable hinge provided in the present application can adjust the angle of the first arm 31 or the second arm 32 in the accommodating groove relative to the cover plate by axially rotating the adjusting screw 7, thereby avoiding the cantilevering of the hinge arm 3 and the cover plate, ensuring that the center of gravity of the hinge arm 3 is located in the accommodating groove, avoiding the increase in torque, and even if used for a long time, the connection between the hinge arm 3 and the cabinet body will not be loose, deviated, or detached, thereby greatly prolonging the service life.
