DETAILED DESCRIPTION

[0028] In order to make the above features and advantages of the utility model more obvious and easy to understand, the following specific examples are given, and the detailed description is as follows in conjunction with the drawings.

[0029] As Figures 1-7 shown, the embodiment provides a dual-purpose ammunition lock that can be unlocked with a mechanical key, which comprises a front shell 1, a transition shell 2, a lock warehouse 3, a first armature 4, a second armature 5, a mechanical drive assembly 6, an electric control drive assembly and a detection assembly 8.

[0030] The front shell 1, the transition shell 2 and the lock warehouse 3 are arranged in sequence from left to right, the lock warehouse 3 is formed with a lock mouth 31 penetrating through both sides, and the first armature 4 and the second armature 5 are rotatably connected in the lock warehouse 3 and located on both sides of the lock mouth 31; specifically, the first armature 4 comprises a first rotating part 41, a first top limiting part 42 and a first connecting part 43, the first top limiting part 42 is located on one side of the first rotating part 41 and faces the second armature 5, and the first connecting part 43 is connected to the peripheral surface of the first rotating part 41, the first connecting part 43 is formed with an extension knob 431 extending into the transition shell 2, the transition shell 2 and the lock warehouse 3 have a strip limiting hole 21, the extension knob 431 extends from the strip limiting hole 21, and the strip limiting hole 21 is used to limit the distance of the forward and backward movement of the extension knob 431, as shown in FIG. 3, the rotation of the first armature 4 is realized by the forward and backward movement of the extension knob 431.

[0031] Preferably, the peripheral surface of the first armature 4 is formed with a limiting protrusion 44 near one side of the lock mouth 31, and the limiting protrusion 44 limits the rotation angle of the first armature 4.

[0032] The second armature 5 and the locking jaw 31 form a locking area. Specifically, the second armature 5 includes a second rotating part 51, a first extension part 52 and a second extension part 53. The first extension part 52 and the second extension part 53 are connected to one side of the second rotating part 51 and face the same direction. There is a gap between the first extension part 52 and the second extension part 53. The end of the first extension part 52 is adapted to the first abutting and limiting part 42. A pressing part 54 is formed on the circumferential surface of the second armature 5.

[0033] Preferably, the first abutting and limiting portion 42 forms a limiting notch 421, which is adapted to the end of the first extension portion 52. When the second armature 5 is in the closed state, such as Figure 5 As shown, the limiting notch 421 of the first abutting limiting part 42 corresponds to the end of the first extension part 52. When the second armature 5 rotates, the end will abut against the side wall at the limiting notch 421.

[0034] The mechanical drive assembly 6 releases the restriction on the second armature 5 by driving the first armature 4 to rotate. Specifically, the mechanical drive assembly 6 includes a lock cylinder 61 and a latch actuating armature 62. The latch actuating armature 62 is connected to the inward side of the lock cylinder 61. Specifically, the lock cylinder 61 drives the latch actuating armature 62 to rotate, such as... Figure 7 As shown, the inner end of the lock cylinder 61 has a strip-shaped block with arc-shaped ends. The latch armature 62 has a rotating groove, which is composed of two fan-shaped grooves. The strip-shaped block is located in the rotating groove. When the strip-shaped block rotates, it will spin freely for a period of time and then press against the inner wall of the rotating groove, causing the latch armature 62 to rotate.

[0035] The latch actuating armature 62 is used to move the extension actuating rod 431 back and forth. The lock cylinder 61 is installed in the front housing 1 and extends into the transition housing 2. The extension actuating rod 431 extends into the transition housing 2. The latch actuating armature 62 is located in the transition housing 2. A triangular protrusion 621 is formed at the end of the latch actuating armature 62. During the unlocking process, the inclined surface of the triangular protrusion 621 contacts the circumferential surface of the extension actuating rod 431.

[0036] The electrically controlled drive assembly releases the restriction on the second armature 5 by driving the first armature 4 to rotate. Specifically, the electrically controlled drive assembly includes a sensing panel and an electromagnetic assembly. The sensing panel is located on the outer side of the front housing, and the sensing panel and the electromagnetic assembly are electrically connected. The electromagnetic assembly includes an electromagnet 7, an iron core 71, and a return spring 72. Figure 6As shown, the electromagnet 7 surface has a sliding groove, the core 71 is clamped in the sliding groove to slide forward and backward, and the reset spring 72 is used to drive the core 71 to reset. Specifically, the core 71 is provided with a clamping table 711 at the end, the reset spring 72 is sleeved on the peripheral surface of the core 71 and located between the clamping table and the electromagnet 7, the end of the core 71 is connected with a sleeve ring 73, the extension driving rod 431 passes through the sleeve ring 73, the inner diameter of the sleeve ring 73 is larger than the diameter of the extension driving rod 431, and the core 71 drives the extension driving rod 431 to move forward and backward by pushing or retracting. Through the induction sheet, that is, the card with a chip set in the prior art, when the card is attached to the surface of the front shell 1 and is sensed by the induction panel, the induction panel generates an electrical signal to the electromagnet 7, the electromagnet 7 is energized to attract the core 71, so that the core 71 retracts to drive the extension driving rod 431 to move, thereby realizing the rotation of the first armature 4. When it is necessary to lock, the core 71 is pushed out under the action of the reset spring 72, thereby driving the first armature 4 to reset.

[0037] In another embodiment, the electromagnet assembly adopts an electrically controlled telescopic structure, such as an electric cylinder.

[0038] The detection assembly 8 further comprises a micro switch installed in the lock chamber 3 and close to the second armature 5; the peripheral surface of the second armature 5 is formed with a pressing portion 54, and the second armature 5 drives the sensing end of the micro switch by rotating the pressing portion 54, when the second armature 5 is in the open state, such as Figure 4 As shown, during the counterclockwise rotation of the limiting protrusion 44, the sensing end (the sensing end is a push plate in this scheme) of the micro switch is pressed, which represents that the second armature 5 is in the open state. The micro switch in this scheme is a product in the prior art, and will not be described here.

[0039] In this scheme, the first armature 4 is reset to the position of the second armature 5 in the closed state after each opening, which is achieved by providing a reset torsional spring at the first rotating portion 41 of the first armature 4 or by a reset pushing mode of the cylinder 7. When the lock ring is pushed into the lock opening 31, the lock ring presses against the first extension portion 52 to make the second armature 5 rotate, and the first extension portion 52 also presses against the first pressing limiting portion 42 of the first armature 4 during rotation, so that the first armature 4 is deflected and then reset. When the first armature 4 is reset, the first pressing limiting portion 42 will limit the rotation of the first extension portion 52 of the second armature 5.

[0040] In this scheme, a mechanical driving assembly or an electrically controlled driving assembly is provided in the cartridge lock to drive the first armature to rotate (that is, to mechanically unlock by a key or to unlock by card swiping by chip induction), which can ensure the rapidity of unlocking and the durability and safety of the cartridge lock.
