DETAILED DESCRIPTION

[0031] The following examples are used to further illustrate the content of the utility model, but do not limit the application of the utility model. Embodiment 1:

[0032] See also Figure 1-Figure 14A hinge structure includes a hinge A3 and a hinge B4 for controlling the opening and closing of a cabinet door 1 on a cabinet body 2. A shaft bushing A5 for rotating an axle pin 7 and a shaft bushing B6 for fixing the axle pin 7 are respectively connected in interference fit in the sleeve holes on one side of the hinge A3 and the hinge B4. The hinge A3 is intermittently matched with an axle pin 7 for controlling the rotation direction of the hinge B4 through the shaft bushing A5. A magnetic ring 8 for magnetic induction is fixed at one end of the axle pin 7 (the diameter of the magnetic ring 8 is smaller than the diameter of the axle pin 7). A magnetic induction module 9 for sensing the position of the magnetic ring 8 is provided through the magnetic induction of the magnetic ring 8. The magnetic induction module 9 is clamped on the other side of the hinge A3. The other end of the shaft pin 7 is provided with a keyway 10 and a key tooth 11 for engagement, and is engaged in the circular hole of the shaft bushing B6 through the keyway 10 and the key tooth 11, and is fixed in the sleeve hole of the hinge B4 through the shaft bushing B6. The sleeve hole of the hinge B4 is rotated on the upper part of the sleeve hole of the hinge A3 through the shaft pin 7. The sleeve hole of the hinge A3 and the sleeve hole of the hinge B4 are contacted and connected with an annular gasket 12 for preventing rotational friction between the hinge A3 and the hinge B4. The upper end of the annular gasket 12 is contacted and connected with the bottom of the sleeve hole of the hinge B4, and the lower end of the annular gasket 12 is contacted and connected with the top of the sleeve hole of the hinge A3.

[0033] See also Figure 1-Figure 4 and Figure 8-Figure 11 , a magnetic induction head 13 for sensing the magnetic ring 8 is protruding from the end side of the magnetic induction module 9, the magnetic induction head 13 passes through the square hole of the hinge A3 into the sleeve hole of the hinge A3 and extends to be snapped into the magnetic bayonet 14 on the end side of the shaft bushing A5, the magnetic induction head 13 is connected to the magnetic ring 8 by gap magnetic induction through the magnetic bayonet 14, the magnetic ring 8 is connected to a controller for controlling the locking position of the electronic lock 15 through the signal of the magnetic induction head 13 (the functions and structures of conventional equipment such as controllers are well known in the art, and the connection settings are also common knowledge, so no further explanation is given here, and it is not shown in the drawings), the controller controls the connection of the electronic lock 15 for locking the cabinet door 1 through the magnetic ring 8 and the magnetic induction head 13 connected by gap magnetic induction;

[0034] The electronic lock 15 includes a lock hook 151 and a lock latch 152 , and the lock latch 152 is connected to the lock hook 151 in a rotational locking manner through a controller.

[0035] See also Figure 1 , Figure 3-Figure 10 and Figure 12-14 A step A16 for interference connection is provided in the sleeve hole of the hinge A3, and a groove A17 for matching the step A16 to install the shaft bushing A5 in the sleeve hole of the hinge A3 is provided at one end of the shaft bushing A5, and the groove A17 is matched with the step A16, and the groove A17 is provided on the opposite side of the magnetic bayonet 14;

[0036] The other end of the shaft bushing A5 is divided into a plane and an inclined surface. The plane of the other end of the shaft bushing A5 is provided with two symmetrically arranged pits 18 for the hinge B4 to be positioned.

[0037] One end of the shaft bushing B6 is provided with a groove B19 for matching the shaft bushing B6 with the sleeve hole of the hinge B4. The groove B19 is provided with a step B20 fixed in the sleeve hole of the hinge B4. The shaft bushing B6 is interference-connected in the sleeve hole of the hinge B4 through the step B20 and the groove B19 provided in cooperation. The step surface of the step B20 is provided at an angle of 5 degrees with the sleeve hole center of the hinge B4, so that the inclined surface of the shaft bushing A5 and the inclined surface of the shaft bushing B6 generate an inward thrust after contact, so that there is a force of close contact between the cabinet door 1 and the cabinet body 2 under the action of its own gravity, forcing the electronic lock 15 to lock the cabinet door 1 on the cabinet body 2 under the thrust, effectively improving the fit between the cabinet door 1 and the cabinet body 2, thereby ensuring the preservation effect of the items in the cabinet body 2;

[0038] The other end of the shaft bushing B6 is divided into a plane and an inclined surface. The inclined surface of the other end of the shaft bushing B6 is rotatably contacted and connected with the inclined surface of the other end of the shaft bushing A5 through the hinge B4 and the shaft pin 7, so that the hinge structure has the function of gravity self-closing, which solves the problem that the service life of the torsion spring hinge is affected by the number of opening and closing times, and effectively improves the service life of the hinge structure;

[0039] Two symmetrically arranged protrusions 21 are provided on the plane at the other end of the shaft bushing B6 and are used to cooperate with the pit 18 to lock the hinge B4. The protrusions 21 are arranged in cooperation with the pit 18, and the bottom of the shaft bushing B6 is locked on the top of the shaft bushing A5 by cooperating with the protrusions 21 and the pit 18, so that the hinge B4 can be located on the hinge A3 at the lower limit of the shaft bushing B6 locking position, which solves the problem of damage to the hinge structure due to the reverse rotation of the cabinet door 1, and effectively improves the stability and safety of the hinge structure.

[0040] The working principle and use process of the utility model: Figure 1-Figure 14 As shown in the figure, after the hinge structure is assembled, the operator installs the hinge structure as a whole on the furniture cabinet (the functions and structures of conventional equipment such as furniture cabinets are well known in the art, and the connection settings are also common knowledge, so no further explanation is given here, and it is not shown in the drawings), the purpose of which is to make the cabinet door 1 of the furniture cabinet more easily fit closely to the cabinet body 2, thereby ensuring the preservation effect of the items in the cabinet body 2;

[0041] When the cabinet door 1 of the furniture cabinet is in a closed state, the inclined surface of the shaft bushing A5 is in a contact connection state with the inclined surface of the shaft bushing B6 (such as Fig.12As shown), at this time, the end face of the magnetic sensing head 13 is opposite to the magnetic ring 8 and can sense the magnetic force of the magnetic ring 8, and transmit the sensed magnetic force signal to the controller. The controller controls the lock latch 152 of the electronic lock 15 to rotate and lock on the lock hook 151 while receiving the magnetic force signal, so that the cabinet door 1 is tightly attached to the cabinet body 2 under the locking of the electronic lock 15;

[0042] When the cabinet door 1 of the furniture cabinet needs to be opened, the operator will first use the key to disengage the latch 152 of the electronic lock 15 from the lock hook 151, and then open the cabinet door 1. At this time, the hinge B4 will rotate synchronously with the cabinet door 1 opening, and the inclined surface of the shaft bushing B6 will rotate relatively along the inclined surface of the shaft bushing A5. At the same time, the hinge B4 will be lifted up by the action of the inclined surface, and the magnetic ring 8 on the shaft pin 7 will move up under the lifting of the hinge B4, leaving the sensing range of the magnetic sensing head 13, until the plane of the shaft bushing B6 is in contact with the plane of the shaft bushing A5. Since there is a pit 18 on the plane of the shaft bushing A5 and a protrusion 21 on the plane of the shaft bushing B6, the protrusion 21 will be stuck in the pit 18 while the plane of the shaft bushing B6 is in contact with the plane of the shaft bushing A5 (such as Fig.13 As shown), at this time, the hinge B4 will be located on the hinge A3 when the protrusion 21 is stuck in the lower limit of the pit 18. At the same time, the cabinet door 1 will stop rotating under the limit of the hinge B4 and will not rotate in the opposite direction;

[0043] When the cabinet door 1 is gently pushed closed, the inclined surface of the shaft bushing B6 moves down along the inclined surface of the shaft bushing A5 under the action of the self-gravity of the cabinet door 1, so that the cabinet door 1 has a self-closing power. At the same time, the magnetic ring 8 on the shaft pin 7 will also move down until the end surface of the magnetic ring 8 and the magnetic sensing head 13 are aligned. At this time, the magnetic sensing head 13 will sense the magnetic force of the magnetic ring 8 and transmit the sensed magnetic signal to the controller. The controller will control the rotation lock of the latch 152 of the electronic lock 15 to be located on the lock hook 151 while receiving the magnetic signal, so that the cabinet door 1 is tightly fitted on the cabinet body 2 under the locking of the electronic lock 15, completing the locking operation of the cabinet door 1 and the cabinet body 2. Embodiment 2:

[0044] See also Figure 1-Figure 14 As another object of the utility model, a furniture cabinet is provided, including a cabinet body 2 and a cabinet door 1. The above hinge structure is provided in the furniture cabinet, that is, the other side of the hinge A3 is fixed to the cabinet body 2, and the other side of the hinge B4 is fixed to the cabinet door 1. The cabinet door 1 is opened and closed with the cabinet body 2 through the hinge B4 and the hinge A3. Therefore, the furniture cabinet can obtain any beneficial effect of the hinge structure described above, which will not be repeated here.
