[0041] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0042] Reference below Figures 1-9 The following describes a cabinet lock cylinder 10, an electronic lock, and a communication equipment cabinet according to an embodiment of the present invention.

[0043] The cabinet lock cylinder 10 of the embodiment of the present invention includes a locking shaft 1 , a driving member 2 , a core body 3 and a first lock tongue 4 .

[0044] The locking shaft 1 has a first end and a second end that are relatively arranged along its axial direction. The driving member 2 is arranged at the first end so that the locking shaft 1 can be driven to rotate by the driving member 2. A spiral guide groove 11 and a reset linear groove 12 are provided on the outer peripheral wall of the locking shaft 1. The spiral guide groove 11 is connected with the reset linear groove 12. The spiral guide groove 11 and the reset linear groove 12 form an unlocking position 101 and a locking position 102 at the connection point; the first lock tongue 4 is arranged on the end of the core body 3 away from the driving member 2, and the core body 3 has a limiting protrusion 32. The limiting protrusion 32 can be alternately movably arranged in the spiral guide groove 11 and the reset linear groove 12 to drive the first lock tongue 4 to extend into or exit the locking hole 621 to achieve unlocking and locking.

[0045] The cabinet lock cylinder 10 of the present invention is characterized by providing a spiral guide groove 11 and a reset linear groove 12 on the outer peripheral wall of the locking shaft 1. The limiting protrusion 32 is alternately arranged in the spiral guide groove 11 and the reset linear groove 12, thereby driving the first lock tongue 4 to extend into or out of the locking hole 621 to achieve unlocking and locking. In other words, the motion structure adopts a fixed track (the spiral guide groove 11 and the reset linear groove 12) to have a limited trajectory during movement and will not be subject to any forward resistance. In addition, the driving member 2 moves in one direction, which makes it easier to control the driving member 2 and makes the lock cylinder structure more stable and reliable. The driving member 2 is used to drive the locking shaft to move between the locked position and the unlocked position 101. When the limiting protrusion 32 is in the locked position 102, unlocking can only be achieved by rotating the driving member 2. When the cabinet lock cylinder 10 is subjected to external impact or suction, the limiting protrusion 32 will not leave the locked position, preventing the electronic lock from automatically unlocking.

[0046] Therefore, the cabinet lock cylinder 10 according to the embodiment of the present invention has the advantage of high control convenience.

[0047] like Figure 3 、 Figure 6 and Figure 7 As shown, the core 3 includes a cylinder 31 and a limiting protrusion 32 provided on the inner peripheral wall of the cylinder 31 . The cylinder 31 is slidably sleeved on the locking shaft 1 , and one end of the cylinder 31 is connected to the first locking tongue 4 .

[0048] The cabinet lock cylinder 10 of the present embodiment improves the stability of the fit between the core 3 and the locking shaft 1 by arranging the core 3, which includes a cylindrical body 31 and a limiting protrusion 32 provided on the inner circumferential wall of the cylindrical body 31, and the cylindrical body 31 is slidably mounted on the locking shaft 1. Furthermore, the cylindrical body 31 can also limit the sliding trajectory of the limiting protrusion 32. As a result, the cabinet lock cylinder 10 has the advantage of good structural stability.

[0049] like Figure 3 、 Figure 4 、 Figure 6 and Figure 7 As shown, the cabinet lock core 10 of the embodiment of the present invention also includes a reset spring 5. The end of the cylinder 31 connected to the first lock tongue 4 is a seal. The reset spring 5 is arranged in the cylinder 31, and the two ends of the reset spring 5 are respectively connected to the locking shaft 1 and the seal. The reset spring 5 is used to apply a force to the core 3 to move the core 3 to the locking position 102.

[0050] Optionally, the cross-sectional area of ​​the cylinder 31 is larger than the cross-sectional area of ​​the core 3 so as to form a limiting step portion between the cylinder 31 and the core 3 .

[0051] In the cabinet lock core 10 of the present embodiment, the return spring 5 disposed within the cylinder 31 can apply a force to the core body 3 to move the core body 3 toward the locked position 102. This allows the first lock tongue 4 to automatically extend into the locking hole 621 to achieve locking, thereby providing the cabinet lock core 10 with the advantage of high security.

[0052] like Figure 3 and Figure 4 As shown, the reset spring 5 is a compression spring, and the reset linear groove 12 extends along the axial direction of the locking shaft 1. The reset linear groove 12 has an unlocking end (unlocking position 101) and a locking end (locking position 102) arranged opposite to each other along the axial direction of the locking shaft 1. The unlocking end is arranged near the driving member 2. The two ends of the spiral guide groove 11 are connected to the two ends of the reset linear groove 12 to form the unlocking position 101 and the locking position 102 at the connection point. The driving member 2 can drive the locking shaft 1 to rotate, thereby driving the first locking tongue 4 to exit the locking hole 621. The compression spring can drive the cylinder 31 to move in a direction away from the driving member 2, thereby driving the first locking tongue 4 to extend into the locking hole 621. It can be understood that the unlocking position 101 and the locking position 102 are at the two ends of the reset linear groove 12.

[0053] The cabinet lock core 10 of the present invention, by configuring the return spring 5 as a compression spring, can apply a force to the core body 3 to move the core body 3 toward the locked position 102. Thus, the first lock tongue 4 is automatically inserted into the locking hole 621 to achieve locking, thereby providing the cabinet lock core 10 with the advantage of high security.

[0054] The electronic lock of the present utility model embodiment includes a lock body 20, a sensor, a locking member 30, and a cabinet lock core 10 according to any of the above items. The lock body 20 has a limiting cavity and a limiting groove. The locking member 30 is arranged on the lock body 20. The locking member 30 has a locking hole 621. The locking hole 621 and the limiting groove are arranged correspondingly in the axial direction of the locking shaft 1. The locking shaft 1 and the driving member 2 are arranged in the limiting cavity. The core 3 and the first lock tongue 4 are movably arranged in the limiting cavity. In the locked position 102, the first lock tongue 4 can extend out of the limiting groove and penetrate into the locking hole 621. The sensor is electrically connected to the driving member 2. The locking member 30 has a second lock tongue 64 that engages the cabinet body. It can be understood that the notch of the limiting groove is arranged toward the locking member 30.

[0055] The electronic lock of the present invention has the advantage of high control convenience. In addition, the lock body 20, sensor, and locking member 30 are provided, and the second lock tongue 64 of the locking member 30 engages with the cabinet body to achieve locking. This can replace the original mechanical lock, making the electronic lock more stable and reliable.

[0056] Optionally, the electronic lock of the embodiment of the present invention further includes a control mainboard, which is electrically connected to the sensor and the driving member 2 .

[0057] Furthermore, the controller can draw power through the NFC channel, communicate with the control terminal (such as a mobile phone) while drawing power, unlock after successful authentication, and achieve unlimited battery life without the need for a built-in battery.

[0058] The lock features a passive design, requiring no internal batteries, and uses Bluetooth or NFC technology for wireless remote control. Furthermore, the lock's appearance matches the mechanical lock slots reserved for communication cabinets, making it a direct replacement for existing mechanical locks, facilitating easy installation and use.

[0059] like Figures 3 to 9 As shown, the locking member 30 includes a handle 61, a lock beam 62, a limit shaft 63 and a second lock tongue 64. The limit shaft 63 is rotatably arranged on the lock body 20. One end of the handle 61 is hinged to one end of the limit shaft 63. The limit shaft 63 extends along an axial direction perpendicular to the locking axis 1. The other end of the limit shaft 63 is connected to the second lock tongue 64. The second lock tongue 64 has a limit portion. A limit hole is provided on the cabinet. In the unlocking position 101, the limit portion corresponds to the limit hole to achieve unlocking. The other end of the handle 61 is connected to the lock beam 62. The lock body 20 has an insertion slot 711. In the locking position 102, the lock beam 62 is inserted into the insertion slot 711. The lock beam 62 has a locking hole 621. The first lock tongue 4 can extend out of the limit slot and penetrate into the locking hole 621.

[0060] The electronic lock of the embodiment of the utility model is characterized by dividing the locking member 30 into a handle 61, a lock beam 62, a limiting shaft 63, and a second lock tongue 64. The second lock tongue 64 is mechanically fixed to the cabinet body. To unlock the second lock tongue 64, the first lock tongue 4 must be unlocked first. When the cabinet door is frequently used, the cabinet door can be closed simply by engaging the second lock tongue 64 with the cabinet body. When locking is required, the first lock tongue 4 can extend out of the limiting groove and penetrate into the locking hole 621 for electronic locking. When unlocking, the signal controls the driving member 2 to rotate to achieve the unlocked position 101. Therefore, the electronic lock has the advantages of wide application scenarios and high convenience.

[0061] In addition, one end of the locking member 30 along the axial direction of the locking shaft 1 is hinged to the lock body 20, and the other end of the locking member 30 has a locking beam 62, which hinges the locking member 30 to the lock body 20. This not only ensures that the locking member 30 does not separate from the lock body 20 when in the unlocked position 101, thereby preventing it from being lost during repeated unlocking and locking, but also serves as a positioning function, so that locking can be achieved by simply pressing the locking member 30 downward. In the locked position 102, it can also cooperate with the core body 3 to form a whole, realizing the anti-theft function of the electronic lock.

[0062] Optionally, the limiting portion may be a triangular, quadrangular, pentagonal or hexagonal column, and the shape of the limiting hole is consistent with the shape of the limiting portion.

[0063] like Figures 8 and 9 As shown, the lock body 20 includes a lock shell 71 and a first limiting plate 72 and a second limiting plate 73 arranged in the limiting cavity of the lock shell 71, the core body 3 and the first lock tongue 4 are movably arranged in the lock shell 71, the first limiting plate 72 and the second limiting plate 73 are arranged in the lock shell 71 along the axial direction of the locking shaft 1 so as to divide the limiting cavity into an installation cavity and a limiting cavity, the driving member 2 is arranged in the installation cavity, and the locking shaft 1 is rotatably passed through the first limiting plate 72, the core body 3 is slidably arranged in the limiting cavity, and the second limiting plate 73 has a limiting groove.

[0064] The electronic lock of the present embodiment has the advantage of good structural stability by dividing the lock body 20 into a lock housing 71 and a first limiting plate 72 and a second limiting plate 73 disposed within a limiting cavity of the lock housing 71. The locking shaft 1 is rotatably passed through the first limiting plate 72, the core 3 is slidably disposed within the limiting cavity, and the second limiting plate 73 can limit the core 3.

[0065] It can be understood that, relative to the first limiting plate 72 , the second limiting plate 73 is disposed closer to the locking beam 62 .

[0066] Furthermore, the electronic lock of the embodiment of the present invention further includes two partitions arranged in the transverse direction of the limiting cavity, and the two partitions are arranged at intervals to form the limiting cavity of the core 3.

[0067] like Figure 4 As shown, the electronic lock of the embodiment of the present invention also includes an elastic member 8, and one end of the handle 61 along the axial direction of the locking shaft 1 is hinged to the outer wall of the lock shell 71, and the other end of the handle 61 has a lock beam 62, and the lock shell 71 has an insertion groove 711. In the locking position 102, the lock beam 62 is inserted into the insertion groove 711 and elastically abuts against the elastic member 8.

[0068] In the electronic lock of this embodiment, in the locked position 102, an elastic member 8 is provided to abut the lock beam 62 and eject the unlocked lock beam 62. During use, the handle 61 is manually rotated to unlock the second lock tongue 64 from the cabinet. The elastic member 8 can eject the hidden handle 61, indicating that mechanical unlocking is possible. As a result, this electronic lock offers the advantage of convenient operation.

[0069] like Figure 4 As shown, the elastic member 8 is a torsion spring, and a positioning column is provided on the lock body 20. The positioning column has a positioning groove. The main body of the torsion spring is passed through the positioning column, and one end of the torsion spring is stuck in the positioning groove. In the locking position 102, the torsion spring can elastically abut against the lock beam 62.

[0070] The electronic lock of the embodiment of the present invention is configured such that the elastic member 8 is a torsion spring, one end of which is clamped in the positioning groove. In the locked position 102, the torsion spring can elastically abut against the lock beam 62. When unlocking, the locking member 30 can be ejected. The electronic lock has the advantage of being easy to operate.

[0071] The embodiments of the present invention are not limited to this. For example, in other embodiments, an elastic limiting groove is provided on the lock body 20, and the elastic member 8 is arranged in the elastic limiting groove. The elastic limiting groove extends in a direction perpendicular to the locking axis 1, and the opening of the elastic limiting groove is arranged toward the lock beam 62, and in the locking position 102, the elastic member 8 abuts against the lock beam 62.

[0072] The electronic lock of the embodiment of the present utility model has an elastic limiting groove provided on the lock body 20, and the elastic limiting groove extends in a direction perpendicular to the locking shaft 1. Therefore, the electronic lock has the advantage of a simple structure.

[0073] During operation, the sensor is installed in the lock body 20, the core 3 and the first lock tongue 4 are installed in the limiting cavity, and the controller controls the rotation of the driving member 2, which causes the locking shaft 1 to rotate accordingly, thereby driving the cylinder 31 and the limiting protrusion 32 to move along the locking shaft 1, thereby enabling the first lock tongue 4 to extend into or out of the locking hole 621 to lock the locking member 30. After this part is unlocked, the elastic member 8 can eject the lock beam 62, and then the handle 61 is rotated. When the second lock tongue 64 is aligned with the limiting hole, the cabinet door can be unlocked.

[0074] The communication equipment cabinet of the embodiment of the present invention includes a cabinet body, a cabinet door and an electronic lock according to any one of the above items. The cabinet door is hinged on the cabinet body, the lock body 20 and the cabinet lock core 10 are arranged on the cabinet door, and the locking member 30 is engaged with the cabinet body.

[0075] Therefore, the communication equipment cabinet of the embodiment of the present invention has the advantage of high control convenience.
