[0026] The following is a detailed description of the embodiments of the utility model in conjunction with the accompanying drawings. It should be clear that the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1-6 As shown, in some illustrative embodiments, a key management device is provided, including: a key card 1, a locking assembly 2, a card box 3, a box plate 4, a circuit board 5, a panel 6 and a display screen 7.

[0028] The panel 6 is arranged in a cabinet, and the space in the cabinet is divided into two spaces, front and back. The space in front of the panel 6 is the operation space for the key access personnel. The box plate 4 and the display screen 7 in this embodiment are located in the front of the panel 6. The space in the back of the panel 6 is used to accommodate the data processing part, such as the controller, power supply, wiring harness, etc. At the same time, the locking assembly 2, the card box 3 and the circuit board 5 in this embodiment are located in the back of the panel 6.

[0029] The key card 1 comprises a casing 101 , a card plate 102 , and a U-shaped buckle 103 .

[0030] The clamping plate 102 is disposed in the casing 101 and can move in the casing 101. Position-limiting lock grooves 104 are provided on both sides of the clamping plate 102, and a stop pin 105 is provided on the inner shell wall of the casing 101. The stop pin 105 is embedded in the position-limiting lock groove 104, that is, the end of the stop pin 105 extends into the groove space of the position-limiting lock groove 104. The stop pin 105 realizes the position-limiting effect on the clamping plate 102, so that the clamping plate 102 cannot completely escape from the casing 101.

[0031] Optionally, a reset spring is disposed in the sleeve shell 101, and one end of the reset spring is connected to the inner shell wall of the sleeve shell 101, and the other end is connected to the rear end of the card plate 102, so as to realize automatic reset of the card plate 102. The reset of the card plate 102 can also be realized through other existing structural forms.

[0032] A hinge seat 106 and a clamp seat 107 are respectively disposed on both sides of the front end of the clamp plate 102. One end of the U-shaped buckle 103 is hinged to the hinge seat 106, and the other end is plugged into the clamp seat 107. Figure 6 As shown, a notch 1071 is provided on the holder 107, and two arc-shaped protrusions 1072 are symmetrically arranged on the inner wall of the notch 1071. Arc-shaped grooves matching the arc-shaped protrusions 1072 are arranged on both sides of one end of the U-shaped buckle 103 plugged into the holder 107. The matching means that the arc-shaped protrusions 1072 can be embedded in the arc-shaped grooves.

[0033] The clamping plate 102 and the U-shaped buckle 103 together constitute a mounting mechanism for fixing the key, and the position of the hinge seat 106 and the clamping seat 107 is the opening and closing position of the mounting mechanism. When the key needs to be replaced, the U-shaped buckle 103 is pulled out of the casing 101 until the opening and closing position is located outside the casing 101. At this time, the U-shaped buckle 103 is pried open to separate the U-shaped buckle 103 from the clamping seat 107 to form an opening. After the key is replaced, the U-shaped buckle 103 is buckled, and the end of the U-shaped buckle 103 is reinserted into the notch 1071, and the arc-shaped protrusion 1072 is again embedded in the arc-shaped groove to complete the closure of the U-shaped buckle 103.

[0034] The clamping seat 107 and the U-shaped buckle ring 103 are made of metal with a certain degree of deformation ability, so the above clamping method is feasible.

[0035] After the U-shaped buckle 103 is closed, the U-shaped buckle 103 can be pushed into the shell 101. Furthermore, the reset spring resets the position of the clamping plate 102 and tightens the clamping plate 102, so that the opening and closing position is hidden in the shell 101. The connection is stable and not easy to fall off during use. In addition, the method of changing the key is also convenient. You only need to pull out the mounting mechanism and open the U-shaped buckle 103.

[0036] The locking assembly 2 includes: an electromagnetic lock 201, a first locking tongue 202, a second locking tongue 203, and a contact switch 204. The electromagnetic lock 201 is a normally closed electromagnetic lock with power off effected by a spring. When the power is off, the first locking tongue 202 and the second locking tongue 203 are bounced up by the spring inside the electromagnetic lock 201 to lock the housing 101 and the card plate 102. When the power is on, the first locking tongue 202 and the second locking tongue 203 are attracted to the original position and lose the limiting effect on the housing 101 and the card plate 102.

[0037] The shell wall of the casing 101 is provided with a first long hollow groove 1011 at a position corresponding to the position-limiting lock groove 104. The first lock tongue 202 is arranged on the electromagnetic lock 201 and is adapted to the position-limiting lock groove 104, and the adaptation means that the first lock tongue 202 can be embedded in the position-limiting lock groove 104. When the key card 1 is pushed into the cartridge 3, the casing 101 pushes the inclined surfaces of the first lock tongue 202 and the second lock tongue 203 in sequence, so that the first lock tongue 202 and the second lock tongue 203 are retracted to the original position. When the position-limiting lock groove 104 reaches the position of the first lock tongue 202, the first lock tongue 202 bounces up and passes through the first long hollow groove 1011 and then is embedded in the position-limiting lock groove 104, thereby completing the locking of the mounting mechanism.

[0038] The slot width of the locking slot 109 is smaller than the top width of the first locking tongue 202 , so that the first locking tongue 202 cannot be embedded in the locking slot 109 .

[0039] The card box 3 is arranged on the back of the panel 6 for accommodating the key card 1. A through slot communicating with the opening of the card box 3 is provided on the panel 6, and the card box plate 3 is arranged at the opening of the card box 3 and is arranged together with the display screen 7 on the front of the panel 6.

[0040] The two sides of the housing 101 are provided with locking slots 109, and the cartridge 3 is provided with a second long hollow slot 1012 at the position corresponding to the locking slot 109. The second lock tongue 203 is arranged on the electromagnetic lock 201 and is adapted to the locking slot 109, and the adaptation means that the second lock tongue 203 can be embedded in the locking slot 109. When the key card 1 is pushed into the cartridge 3, the housing 101 pushes the inclined surfaces of the first lock tongue 202 and the second lock tongue 203 in turn, so that the first lock tongue 202 and the second lock tongue 203 are retracted to the original position. When the locking slot 109 reaches the position of the second lock tongue 203, the second lock tongue 203 pops up and passes through the second long hollow slot 1012 and then is embedded in the locking slot 109, completing the locking of the key card 1. When the locking assembly 2 is stuck to the key card 1, it can also lock the card plate 102, so that the mounting mechanism cannot be pulled out at the same time, and the locking degree is higher, further reducing the risk of unauthorized use of the key.

[0041] The casing 101 is also provided with a top block 110 for use with the contact switch 204. A card reading coil is provided on the circuit board 5. An installation sink is provided on the outer surface of the casing 101, and an electronic tag 8 is provided in the installation sink. The controller is connected with the card reading coil, the electromagnetic lock 201, the display screen 7, and the contact switch 204. The card reading coil is used to read the information of the electronic tag 8. The controller controls the locking and opening of the electromagnetic lock 201 and the display status of the display screen. After the key card 1 is locked in the cartridge 3, the top block 110 contacts the contact switch 204, and the contact switch 204 notifies the controller that the key card 1 has been inserted in place. The controller controls the card reading coil to start, starts to read the information in the electronic tag 8, transmits the information to the host computer, and displays the key information on the display screen 7 in real time.

[0042] The electromagnetic lock 201 and the contact switch 204 are arranged on the circuit board 5, and the circuit board 5 is fixed to the side of the cassette 3 by screws. A mounting platform 9 is arranged at the cassette opening of the cassette 3, and a first threaded hole and a first through hole are provided on the mounting platform 9, and a second threaded hole and a second through hole are provided on the panel 6, and the positions of the first threaded hole and the second threaded hole correspond to each other, and the positions of the first through hole and the second through hole correspond to each other. The cassette 3 is fixed to the back of the panel 6 by screws, that is, the screws are screwed into the first threaded hole and the second threaded hole, so as to complete the fixing of the cassette 3. An installation pin 401 adapted to the first through hole and the second through hole is arranged on the cassette plate 4, and the installation pin 401 is inserted into the first through hole and the second through hole, so as to complete the fixing of the cassette plate 4.
