[0053] Example 1

[0054] like Figures 1 to 5 As shown, this embodiment discloses a locking device, including a lock disk 100 and a locking mechanism and an unlocking mechanism arranged crosswise with each other, wherein the locking mechanism is selectively connected or disconnected with the lock disk 100, and when the locking mechanism is connected with the lock disk 100, the locking mechanism locks the lock disk 100; when the locking mechanism is disconnected from the lock disk 100, the locking mechanism unlocks the lock disk 100. The unlocking mechanism is used to lock the locking mechanism or unlock the locking mechanism; when the unlocking mechanism locks the locking mechanism, the locking relationship between the locking mechanism and the lock disk 100 is fixed at the same time; when the unlocking mechanism unlocks the locking mechanism, the locking relationship between the locking mechanism and the lock disk 100 is released.

[0055] Furthermore, a first elastic member 210 is provided on the locking mechanism, and a second elastic member 310 is provided on the unlocking mechanism; in this embodiment, both the first elastic member 210 and the second elastic member 310 are springs. When the lock disk 100 is locked, the first elastic member 210 is in a compressed or stretched state, and the second elastic member 310 is in a compressed or stretched state when the lock disk 100 is unlocked; when the lock disk 100 needs to be locked, an external force is applied to the locking mechanism in the direction of the lock disk 100, so that the locking mechanism moves under the action of the external force, thereby connecting with the lock disk 100 and locking the lock disk 100, and the unlocking mechanism limits the locking mechanism under the action of the second elastic member 310 to prevent the locking mechanism from loosening; at the same time, the first elastic member 310 continues to apply a force to the locking mechanism to make it move away from the lock disk 100; when the lock disk 100 needs to be unlocked, the unlocking mechanism is moved to release the limiting effect of the unlocking mechanism on the locking mechanism, and the locking mechanism automatically resets under the action of the first elastic member 210 to disconnect the connection with the lock disk 100; at the same time, the second elastic member 310 continues to apply a force to the unlocking mechanism to make it move to the locking position of the locking mechanism.

[0056] Specifically, in this embodiment, the locking mechanism includes a first locking piece 220, a first notch 221 is provided on the first locking piece 220, and the first locking piece 220 is divided into a first locking part and a second locking part by the first notch 221 as a dividing line. In this embodiment, the first locking part and the second locking part are seamlessly connected and integrally formed. The second locking part is used to connect with the lock disk 100, and a protrusion for locking the lock disk 100 is provided on the second locking part. In this embodiment, the protrusion is arranged at the bottom of the second locking part; the unlocking mechanism includes a first unlocking mechanism 320 and a second unlocking mechanism 330, and the second unlocking mechanism 330 is mainly used to limit the second elastic member 310. Among them, a second notch 321 is provided on the first unlocking mechanism 320, and the first unlocking mechanism 320 is divided into a first unlocking part and a second unlocking part with the second notch 321 as a dividing line. The second unlocking mechanism 330 is arranged at the end of the second unlocking part, and a third notch 331 is provided on the second unlocking mechanism 330 for facilitating the second unlocking part to pass through. The second elastic member 310 is arranged on the second unlocking part, and one end of the second elastic member 310 abuts against the second contact part, and the other end abuts against the second unlocking mechanism 330.

[0057] When the lock disk 100 needs to be locked, a force is applied to the locking mechanism in the direction of the second notch 321, so that the first notch 221 moves in the direction of the second notch 321, and at the same time, the first elastic member 210 is compressed or stretched to continuously apply a force to the locking mechanism to move it away from the lock disk 100; when the first notch 221 moves to the position of the second notch 321, the second notch 321 withdraws from the first notch 221 under the action of the restoring force of the second elastic member 310, and at the same time, the unlocking mechanism is pressed against the position of the first notch 221 by the restoring force of the second elastic member 310, thereby achieving locking; at this time, the second locking portion is connected to the lock disk 100, and the second unlocking portion presses against the position of the first notch 221 to limit the first locking plate 220.

[0058] When the lock plate 100 needs to be unlocked, a force is applied to the unlocking mechanism in the direction of the first notch 221, so that the second notch 321 moves in the direction of the first notch 221, and at the same time, the second elastic member 310 is compressed or stretched, and the second elastic member 310 continuously applies a force to the unlocking mechanism to make it move to the position of the locking mechanism; when the second notch 321 moves to the position of the first notch 221, the first notch 221 withdraws from the second notch 321 under the action of the reset force of the first elastic member 210, and at the same time, the locking mechanism is pressed against the position of the second notch 321 by the reset force of the first elastic member 210, thereby achieving unlocking; at this time, the second locking portion leaves the lock plate 100 and presses against the position of the second notch 321, and the end of the second unlocking portion extends from the third notch 331. That is, the second locking portion restricts the movement of the first unlocking mechanism 320, thereby releasing the limit of the first unlocking mechanism 320 on the locking mechanism.

[0059] Specifically, the first elastic member 210 is arranged in the longitudinal direction of the locking mechanism. When a force is applied to the locking mechanism in the direction of the lock disk 100, the first elastic member 210 is stretched, and the locking mechanism and the first notch 221 are displaced in the longitudinal direction; the second elastic member 310 is arranged in the transverse direction of the unlocking mechanism. When a force is applied to the first unlocking mechanism 320 toward the second unlocking mechanism 330, the second elastic member 310 is compressed, and the unlocking mechanism and the second notch 321 are displaced in the transverse direction.

[0060] Furthermore, the first locking plate 220 is arranged longitudinally, the first locking portion and the second locking portion are respectively arranged above and below the first notch 221, the locking disk 100 is located below the second locking portion, and the first elastic portion provides an upward pulling force for the locking mechanism; when the second locking portion is locked and connected to the locking disk 100, the first elastic member 210 is stretched; the first unlocking mechanism 320 is arranged horizontally, and the first unlocking mechanism 320 moves left and right relative to the first locking plate 220 to limit or release the locking mechanism; when the first unlocking mechanism 320 moves toward the second unlocking mechanism 330, the second elastic member 310 is compressed, and at this time the first unlocking mechanism 320 releases the limit on the locking mechanism, so that the second locking portion is disconnected from the locking disk 100, thereby unlocking the locking disk 100.

[0061] Preferably, the first locking piece 220 and the first unlocking mechanism 320 are vertically connected to each other.

[0062] Furthermore, the locking mechanism further comprises a frame 240 that plays a supporting role, and the frame 240 comprises a vertical surface 241 and a horizontal surface 242 connected in an L shape, wherein the vertical surface 241 is arranged parallel to the first locking plate 220, and a sliding column 250 and a fixed column 260 for being movably connected to the first locking plate 220 are arranged on the vertical surface 241. In this embodiment, the fixed column 260 is a bolt, and the fixed column 260 passes through the sliding column 250 and the first locking plate 220, and is then fixedly connected to the vertical surface 241. The first unlocking mechanism 320 passes through the vertical surface 241, and is then connected to the first locking plate 220; the first locking plate 220 is provided with a movable position 222 for installing the sliding column 250, and the first locking plate 220 moves up and down on the movable position 222; the fixed column 260 passes through the sliding column 250 and is fixedly connected to the vertical surface 241, so that the first locking plate 220 can move up and down relative to the vertical surface 241.

[0063] Specifically, one end of the first elastic member 210 is connected to the vertical surface 241, and the other end is connected to the first locking plate 220, wherein the vertical surface 241 is provided with a first connecting position 244 for connecting the first elastic member 210, and the first locking plate 220 is provided with a second connecting position 223 for connecting the first elastic member 210; when the first locking plate 220 locks the lock disk downward, the first elastic member 210 is in a stretched state.

[0064] Among them, the horizontal plane 242 is arranged between the first locking plate 220 and the locking disk 100, and a fourth notch 243 is provided on the horizontal plane 242 for the first locking part to pass through; when the first locking plate 220 moves downward, the bottom of the first locking plate 220 passes through the fourth notch 243 and is connected to the locking plate to lock the locking disk 100.

[0065] Furthermore, when the locking device is installed on a lamp, the frame 240 can be a horizontal frame on the lamp, wherein the locking device is connected to the lamp through the frame 240 .

[0066] Furthermore, the locking mechanism further includes a slide plate 270 for isolating the vertical surface 241 and the first locking plate 220. The slide plate 270 is used to isolate the vertical surface 241 and the first locking plate 220 on the one hand, and on the other hand, it can also assist the first locking plate 220 in sliding up and down, so that the first locking plate 220 moves more smoothly. In this embodiment, the slide plate 270 is arranged between the vertical surface 241 and the first slide plate 270, and the fixing column 260 passes through the slide plate 270 and is fixedly connected to the vertical surface 241; the first unlocking mechanism 320 passes through the vertical surface 241 and the slide plate 270 in the transverse direction in turn, and is connected to the first locking plate 220.

[0067] Example 2

[0068] like Figures 6 to 8 As shown, this embodiment discloses another locking device, which includes a lock disk 100 and a locking mechanism and an unlocking mechanism that are cross-arranged with each other, wherein the locking mechanism is selectively connected to or disconnected from the lock disk 100, and when the locking mechanism is connected to the lock disk 100, the locking mechanism locks the lock disk 100; the unlocking mechanism is used to lock the locking mechanism or unlock the locking mechanism; when the unlocking mechanism locks the locking mechanism, the locking relationship between the locking mechanism and the lock disk 100 is fixed at the same time; when the unlocking mechanism unlocks the locking mechanism, the locking relationship between the locking mechanism and the lock disk 100 is released.

[0069] Further, the locking mechanism is provided with a first elastic member 210, and the unlocking mechanism is provided with a second elastic member 310; in this embodiment, the first elastic member 210 and the second elastic member 310 are both springs. The first elastic member 210 is in a compressed or stretched state when the lock disk 100 is locked, and the second elastic member 310 is in a compressed or stretched state when the lock disk 100 is unlocked; when the lock disk 100 needs to be locked, an external force is applied to the locking mechanism in the direction of the lock disk 100, so that the locking mechanism moves under the action of the external force, thereby connecting with the lock disk 100 and locking the lock disk 100, and the unlocking mechanism limits the locking mechanism under the action of the second elastic member 310 to prevent the locking mechanism from loosening; when the lock disk 100 needs to be unlocked, the unlocking mechanism is moved to release the limiting effect of the unlocking mechanism on the locking mechanism, and the locking mechanism automatically resets under the action of the first elastic member 210 to disconnect from the lock disk 100.

[0070] Specifically, in this embodiment, the locking mechanism includes a first pressing member 410, a guide member 420 and a fixing member 430 which are arranged in sequence. The first pressing member 410 is arranged to penetrate the guide member 420 and the fixing member 430, and one end of the first pressing member 410 which passes through the fixing member 430 is selectively connected to or disconnected from the lock disk 100; the unlocking mechanism is arranged between the guide member 420 and the fixing member 430, and the first pressing member 410 is further provided with a first notch 411 for abutting against the unlocking mechanism; the first elastic member 210 is arranged between the guide member 420 and the fixing member 430.

When the locking disk 100 needs to be locked, the first pressing member 410 is pressed to move the first pressing member 410 toward the locking disk 100, thereby connecting with the locking disk 100 and locking the locking disk 100. At the same time, the unlocking mechanism protrudes from the first notch 411 under the action of the second elastic member 310, thereby limiting the first pressing member 410 and preventing the first pressing member 410 from loosening.

[0071] Furthermore, when the first pressing member 410 is connected to the locking disk 100, the first elastic member 210 is in a compressed state; when the unlocking mechanism moves out of the first slot 411 to disconnect the first pressing member 410 from the locking disk 100, the second elastic member 310 is in a compressed state.

[0074] When the lock disk 100 needs to be unlocked, the first unlocking member 510 is pushed to move the guide bar 513 toward the second mounting opening 521, so that the first protrusion 512 withdraws from the first slot 411. Under the action of the restoring force of the first elastic member 210, the first pressing member 410 drives the first slot 411 to reset itself to disconnect from the lock disk 100.

[0075] Furthermore, the first pressing member 410, the guide member 420, the first unlocking member 510, the second unlocking member 520 and the fixing member 430 are arranged in sequence from top to bottom, and the first pressing member 410 passes through the guide member 420, the first unlocking member 510, the second unlocking member 520 and the fixing member 430 in sequence; the fixing member 430 is provided with a second slot for installing the first elastic member 210, the first elastic member 210 is longitudinally arranged in the second slot, and the size of the first elastic member 210 is arranged to increase from top to bottom; the first pressing portion is provided with a second protrusion 412 for abutting against the first elastic member 210; the second elastic member 310 is transversely arranged on the guide strip 513, and the first unlocking member 510 drives the first protrusion 512 to move left and right to abut or release the abutment with the first slot 411.

[0076] Furthermore, the first unlocking member 510 is also provided with a third protrusion which is longitudinally arranged and used to push the first unlocking member 510 to move left and right. The third protrusion is arranged on the opposite side of the second elastic member 310 .

[0077] Specifically, in the present embodiment, when it is necessary to lock the lock disk 100, an external force is applied to the first pressing member 410 in the direction of the lock disk 100, so that the first pressing member 410 moves in the direction of the lock disk 100 to achieve a locking connection with the lock disk 100. At the same time, when the first notch 411 on the first pressing member 410 moves downward, the first protrusion 512 on the first unlocking member 510 is acted upon by the second elastic member 310 to move toward the first notch 411 and abut against the first notch 411, thereby limiting and fixing the first pressing member 410, and further fixing the locking relationship between the first pressing member 410 and the lock disk 100.

[0078] When the lock plate 100 needs to be unlocked, the third protrusion is first pushed to move toward the direction of the second elastic member 310, thereby driving the first protrusion 512 to leave the first notch 411, and the first notch 411 and the first pressing member 410 are reset upward under the action of the first elastic member 210, thereby releasing the connection between the first pressing member 410 and the lock plate 100, and unlocking is achieved. At the same time, when the first pressing member 410 is reset upward, the first protrusion 512 abuts against the second protrusion 412 of the first pressing member 410, and the limiting relationship between the first notch 411 and the first unlocking member 510 is released, and the second elastic member 310 is now in a compressed state.
