[0054] The realization of the objectives, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to Figures 1 to 9.

[0055] This application proposes a lock-release mechanism 10 .

[0056] 1 to 9 , in some embodiments of the lock-release mechanism 10 of the present application, the lock-release mechanism 10 includes:

[0057] A locking rod 11, wherein a locking groove 111 is formed on an outer circumferential surface of the locking rod 11, and the locking groove 111 extends along the circumference of the locking rod 11; and

[0058] A locking hook 12 is movably provided on a peripheral side of the locking rod 11 and is used for plugging and cooperating with the locking groove 111 . An end of the locking hook 12 facing away from the locking rod 11 is used for connecting to the light board 30 .

[0059] The locking rod 11 is rotatable along its axial direction and has a locking position and a releasing position. The locking groove 111 includes a first groove body 111a and a second groove body 111b sequentially connected along the circumference of the locking rod 11.

[0060] When the locking rod 11 is in the locking position, the first groove 111a and the locking hook 12 are arranged opposite to each other, so that the locking hook 12 is locked in the first groove 111a;

[0061] When the locking rod 11 is at the releasing position, the second slot 111 b and the locking hook 12 are arranged opposite to each other, so that the locking hook 12 is released from the second slot 111 b.

[0062] In this embodiment, the lock-release mechanism 10 includes a lock rod 11 and a lock hook 12. One end of the lock hook 12 is used to connect to the light board 30, and the other end can be locked and released with the lock slot 111 of the lock rod 11 to achieve locking and releasing of the light board 30. Specifically, the outer circumferential surface of the lock rod 11 is provided with a lock slot 111. The lock slot 111 extends along the circumference of the lock rod 11 and includes a first slot body 111a and a second slot body 111b connected in sequence. The lock hook 12 is movably arranged on the circumferential side of the lock rod 11 and is used to connect to the light board 30. When the lock rod 11 rotates about its axial direction, it can drive the lock slot 111 to move relative to the lock hook 12, so that the first slot body 111a or the second slot body 111b of the lock slot 111 moves to a position opposite to the lock hook 12. When the first slot 111a moves to a position facing the locking hook 12, the locking hook 12 can be locked in the first slot 111a, and then the light board 30 can be locked; when the second slot 111b moves to a position facing the locking hook 12, the locking hook 12 can be detached from the second slot 111b, and then the light board 30 can be released.

[0063] It should be noted that in the related art, the display device 100 generally includes a light board 30 and a housing 20. The housing 20 can quickly lock the light board 30 through an electronic lock to ensure data security. However, the structure of the electronic lock is relatively complex and the cost of use is high.

[0064] Therefore, it can be understood that the technical solution of the present application can achieve locking and releasing cooperation between the lock rod 11 and the lock hook 12. By rotating the lock rod 11, the lock groove 111 on the lock rod 11 can lock or release the lock hook 12, thereby completing the locking and releasing of the light board 30, which is relatively convenient to operate. In addition, the structure of the lock rod 11 and the lock hook 12 is relatively simple, which helps to reduce the cost of using the lock release mechanism 10.

[0065] 5 or 6 , in some embodiments of the lock release mechanism 10 of the present application, the lock hook 12 includes:

[0066] a connecting portion 121 , wherein a first end of the connecting portion 121 is used to connect to the light board 30 , and a second end of the connecting portion 121 is movably disposed in the locking slot 111 ; and

[0067] a stopper 122 connected to an end of the connecting portion 121 facing away from the light board 30 , configured to be inserted into the locking slot 111 and movably arranged along an extension direction of the locking slot 111 so as to reciprocate between the first slot body 111 a and the second slot body 111 b ;

[0068] The cross-sectional area of ​​the stopper 122 is larger than the cross-sectional area of ​​the notch of the first groove 111a, so that the stopper 122 can be stopped in the first groove 111a, so that the locking hook 12 is locked in the first groove 111a;

[0069] The cross-sectional area of ​​the stopper 122 is smaller than the cross-sectional area of ​​the notch of the second groove 111 b , so that the stopper 122 can be disengaged from the second groove 111 b , thereby releasing the locking hook 12 from the second groove 111 b .

[0070] In this embodiment, a locking groove 111 is formed on the outer peripheral surface of the locking rod 11. The locking groove 111 includes a first groove body 111a and a second groove body 111b connected in sequence along the circumference of the locking rod 11. The cross-sectional area of ​​the groove of the first groove body 111a is smaller than the cross-sectional area of ​​the second groove body 111b; the locking hook 12 includes a connecting portion 121 and a stop portion 122. Among them, the cross-sectional area of ​​the connecting portion 121 is not larger than the cross-sectional area of ​​the first groove body 111a, so that the connecting portion 121 can freely enter or disengage from the locking groove 111, that is, the connecting portion 121 is movably arranged in the locking groove 111; the cross-sectional area of ​​the stopping portion 122 is larger than the cross-sectional area of ​​the first groove body 111a, and is not larger than the cross-sectional area of ​​the second groove body 111b, so that the stopping portion 122 can only freely enter or disengage from the second groove body 111b, that is, the stopping portion can be locked in the first groove body 111a when it is arranged opposite to the first groove body 111a, and can be disengaged from the first groove body 111a when it is arranged opposite to the second groove body 111b.

[0071] 3 , in some embodiments of the lock-release mechanism 10 of the present application, the lock rod 11 is provided with a plurality of lock slots 111 , and the plurality of lock slots 111 are sequentially spaced along the length direction of the lock rod 11 ;

[0072] There are a plurality of locking hooks 12 , and each locking hook 12 corresponds to one locking slot 111 .

[0073] In this embodiment, a plurality of locking grooves 111 are provided on the outer circumference of the locking rod 11. The plurality of locking grooves 111 are sequentially spaced along the length of the locking rod 11. Each locking groove 111 can be used to engage with a locking hook 12 for locking and releasing. This arrangement allows each locking hook 12 to be connected to a light board 30, so that a single locking rod 11 can lock and release multiple light boards 30 through multiple locking hooks 12. Of course, the technical solution of the present application is not limited to this. In some embodiments, multiple locking hooks 12 can also be connected to a light board 30 to improve the locking stability of the light board 30.

[0074] Referring to Figures 2 to 7, in some embodiments of the lock-release mechanism 10 of the present application, the lock-release mechanism 10 further includes a rotating member 13, which is disposed at one end of the lock rod 11 and is used to drive the lock rod 11 to rotate so that the lock rod 11 can switch between the locking position and the release position.

[0075] In this embodiment, a rotating member 13 is provided at the end of the locking rod 11 and is used to drive the locking rod 11 to rotate about its axial direction, so that the locking rod 11 switches between the locking position and the releasing position, thereby locking or releasing the locking hook 12 and the light board 30. The rotating member 13 can be driven by manual rotation or can be configured as a power drive mechanism, which is not limited here.

[0076] 5 to 7 , in some embodiments of the lock-release mechanism 10 of the present application, an insertion hole 112 is provided at one end of the lock rod 11 facing the rotating member 13 , and an insertion block 131 is provided at one end of the rotating member 13 facing the lock rod 11 , and the insertion hole 112 and the insertion block 131 are plugged into each other.

[0077] In this embodiment, the socket 112 and the insert block 131 are both extended along the axial direction of the locking rod 11 . By plugging the socket 112 and the insert block 131 into each other, the locking rod 11 and the rotating member 13 can be easily aligned in the axial direction of the locking hook 12 .

[0078] 5 to 7 , in some embodiments of the lock-release mechanism 10 of the present application, a first fixing hole 113 communicating with the insertion hole 112 is defined on the outer wall of the lock rod 11, and a second fixing hole 132 is defined on the outer wall of the insert block 131. The first fixing hole 113 and the second fixing hole 132 are disposed opposite each other along the radial direction of the lock rod 11.

[0079] The lock-release mechanism 10 further includes a positioning member 14 configured to pass through the first fixing hole 113 and the second fixing hole 132 in sequence.

[0080] In this arrangement, by passing the positioning member 14 through the first fixing hole 113 and the second fixing hole 132 in sequence, the positioning member 14 can be fixedly engaged with the locking rod 11 and the insert 131 of the rotating member 13 respectively, thereby realizing the limited fixation of the locking rod 11 and the rotating member 13 in the radial direction of the locking rod 11, thereby improving the position stability between the locking rod 11 and the rotating member 13.

[0081] 4 , in some embodiments of the lock-release mechanism 10 of the present application, a limiting hole 114 is further provided on the outer side wall of the lock rod 11 , and the limiting hole 114 is extended along the circumference of the lock rod 11 .

[0082] In this embodiment, the limiting hole 114 is configured to engage with a limiting structure on the outside of the lock rod 11 to improve the installation stability of the lock rod 11. Furthermore, the limiting hole 114 extends circumferentially along the lock rod 11. Thus, when the lock rod 11 rotates about its axial direction, the limiting hole 114 can move relative to the limiting structure on the outside. In other words, while the limiting structure limits the lock rod 11, it does not interfere with the rotational movement of the lock rod 11, thereby affecting the release function of the lock release mechanism 10.

[0083] In some embodiments of the lock-release mechanism 10 of the present application, the lock-release mechanism 10 further includes a bearing seat 16 , wherein a shaft hole 161 is defined in the bearing seat 16 , and the locking rod 11 is rotatably disposed in the shaft hole 161 .

[0084] In this embodiment, the bearing seat 16 is provided to limit the radial position of the locking rod 11, thereby improving the positional stability of the locking rod 11. In some embodiments, the lock-release mechanism 10 may further include a sleeve that is sleeved around the circumference of the locking rod 11 to reduce rotational friction on the locking rod 11 and facilitate rotational switching of the locking rod 11 between the locked position and the released position.

[0085] Please refer to Figures 8 and 9. In some embodiments of the lock release mechanism 10 of the present application, the lock release mechanism 10 further includes a connecting member 15, and the two ends of the connecting member 15 are respectively used to be detachably connected to the ends of the two locking rods 11, so that one of the locking rods 11 can drive the other locking rod 11 to rotate through the connecting member 15.

[0086] In this embodiment, by making the two ends of the connecting member 15 detachably connected to the ends of the locking rods 11 respectively, the function of motion transmission can be achieved, so that the two adjacent locking rods 11 can achieve synchronous rotation through the connecting member 15.

[0087] This application also provides a display device 100, which includes the lock-release mechanism 10 described in any of the aforementioned embodiments. The specific structure of the lock-release mechanism 10 is similar to that described in any of the aforementioned embodiments. Because the display device 100 provided in this application is applicable to all of the technical solutions in all of the aforementioned embodiments, it possesses at least all of the beneficial effects brought about by the aforementioned technical solutions, which will not be detailed here.

[0088] 1 and 2 , in some embodiments of the lock-release mechanism 10 of the present application, the display device 100 includes:

[0089] A housing 20 having an accommodating space with an opening on one side formed therein;

[0090] a light board 30 , the light board 30 covering the opening; and

[0091] The locking and releasing mechanism 10 is provided in the housing 20 and connected to the light board 30 so as to lock the light board 30 in the opening.

[0092] In this embodiment, the display device 100 includes a shell 20, a light panel 30 and a lock release mechanism 10. The end of the lock release mechanism 10 can protrude from the outside of the shell 20 so that the rotating part 13 of the lock release mechanism 10 can be exposed outside the shell 20. In this way, it is convenient for the user to drive the lock release mechanism 10 to rotate through the rotating part 13.

[0093] In some embodiments, through-holes are respectively formed at opposite ends of the housing 20, and the two ends of the locking mechanism 10 are respectively exposed through the through-holes. In this way, on the one hand, the through-holes can limit the locking mechanism 10, thereby improving the positional stability of the locking mechanism 10. On the other hand, part of the structure of the locking mechanism 10 can be exposed outside the housing 20, so as to facilitate connection and coordination with external devices. For example, in some embodiments, the display device 100 includes a plurality of housings 20, which are arranged side by side and can be spliced ​​together, and each housing 20 is provided with a locking mechanism 10. In this arrangement, the locking mechanisms 10 between adjacent housings 20 can be connected by the connecting member 15 of the aforementioned embodiment, so that the locking mechanisms 10 in the adjacent housings 20 can transmit motion to achieve the locking and releasing function of the plurality of light panels 30 synchronously, which is conducive to improving the convenience of locking and releasing the light panels 30 in the same row in the display device 100.
