[0045] The present application will be further described in detail below in combination with the drawings.

[0046] Please refer to Figures 1 to 4 , a connecting lock buckle provided by an embodiment of the present application, please refer to FIG. 1 to FIG. 4, a connecting lock buckle provided by an embodiment of the present application, which is applied to a display device, and is described by taking the application to the display device as an example, but is not limited to be used only in the display device (refer to Figure 14 ). The connecting lock buckle comprises a fixed component 100 and a lock buckle component 200, the fixed component 100 is connected to a box frame 300 of the display device, the lock buckle component 200 is connected to a bottom shell 410 of a display module 400 of the display device, the lock buckle component 200 is connected with the fixed component 100, so as to assemble the display module 400 on the box frame 300.

[0047] Specifically, also refer to Figure 5 and Figure 6The fixed assembly 100 comprises a connecting seat 110 and a pressing piece 120. The connecting seat 110 is provided with a connecting channel 111, and the connecting channel 111 forms a pressing opening 1111 and a plug-in opening 1112 at two ends of the connecting seat 110 respectively. The pressing piece 120 is arranged in the pressing opening 1111, and the pressing piece 120 is provided with an elastic finger 122 for providing a holding force. The lock assembly 200 comprises a lock seat 210, a lock rod 220, a first locking piece 250 and a first elastic piece 230. The lock seat 210 is provided with a plug-in part 211, the plug-in part 211 extends into the connecting channel 111 through the plug-in opening 1112, and the plug-in part 211 is arranged in the pressing piece 120 from the pressing opening 1111. The plug-in part 211 is provided with a guide channel 212 penetrating the plug-in part 211. The lock rod 220 is slidingly arranged in the guide channel 212. The side of the plug-in part 211 is provided with a first guide hole 213 communicating with the guide channel 212. The first locking piece 250 is movably arranged in the first guide hole 213. The side of the lock rod 220 is provided with a first displacement slot 221. The first elastic piece 230 is arranged to act on the lock rod 220 in the plug-in direction of the plug-in part 211, so that the first displacement slot 221 is separated from the first locking piece 250. The pressing piece 120 is configured to be pressed to push the lock rod 220 to slide from the first position to the second position. When the lock rod 220 is in the first position, the first locking piece 250 is misaligned with the first displacement slot 221, and the lock rod 220 keeps the plug-in part 211 clamped with the connecting seat 110. When the lock rod 220 is in the second position, the first locking piece 250 is aligned with the first displacement slot 221, and the elastic finger 122 abuts against the exposed part of the first locking piece 250, so that the first locking piece 250 is kept embedded in the first displacement slot 221, and the lock rod 220 releases the holding force of the plug-in part 211 clamped with the connecting seat 110.

[0048] The first locking piece 250 can be a ball, but is not limited to a ball. For example, the first locking piece 250 can also be a rod-shaped body with rounded corners at two ends.

[0049] In the specific application process, when the display module 400 is assembled on the box frame 300, the pressing piece 120 does not push the lock rod 220 to move, and the lock rod 220 keeps in the first position under the action of the first elastic piece 230. At this time, the lock rod 220 keeps the plug-in part 211 clamped with the lock seat 210, thereby ensuring that the display module 400 is stably assembled on the box frame 300. When it is needed to disassemble the display module 400 from the box frame 300, the worker presses the pressing piece 120, and the pressing piece 120 pushes the lock rod 220 to shrink in the direction of the guide channel 212, and the lock rod 220 slides from the first position to the second position. At this time, the lock rod 220 releases the holding force of the plug-in part 211 clamped with the connecting seat 110, and the plug-in part 211 can be conveniently pulled out of the connecting channel 111, thereby the display module 400 can be conveniently disassembled from the box frame 300, and the maintenance of the display module is facilitated.

[0050] It should be noted that when the pressing member 120 is pressed, the finger end 1222 of the elastic finger 122 abuts against the first locking member 250, and as the pressing member 120 continuously approaches the insertion portion 211, the elastic finger 122 gradually spreads outward until it slides to the outermost part of the first locking member 250. At the same time, when the locking rod 220 slides to the second position, the first displacement slot 221 coincides with the first guide hole 213, and the elastic finger 122 abuts against the exposed part of the first locking member 250 (see Figure 11 With Figure 12 ), therefore, the side part of the first locking member 250 is embedded into the first displacement slot 221 under the action of the elastic finger 122, so that the locking rod 220 is clamped with the insertion portion 211, and further, the locking rod 220 is kept in the second position relative to the insertion portion 211, correspondingly, the locking rod 220 releases the holding force of the insertion portion 211 clamped with the connecting seat 110. When the display module 400 is detached from the box frame 300, the locking rod 220 is effectively prevented from resetting to the first position under the action of the first elastic member 230, so that the locking rod 220 does not have the holding force of clamping the insertion portion 211 with the connecting seat 110, and the display module 400 is more convenient to detach.

[0051] In some embodiments, referring to Figure 4 , Figure 7 With Figure 8The fixed assembly 100 further comprises a mounting base 130, a pressing seat 140 and a second elastic member 150. The mounting base 130 is assembled or integrally connected with the box frame 300. The connecting seat 110 is integrally connected or assembled with one side of the mounting base 130. When the connecting seat 110 is assembled with the mounting base 130, the two can be fixedly assembled or rotatably assembled, which is specifically set according to actual needs. The pressing seat 140 is assembled with the other side of the mounting base 130. When the connecting seat 110 is rotatably connected with the mounting base 130, the pressing seat 140 can be used to keep the end of the connecting seat 110 mounted on the mounting base 130. The inner side of the pressing seat 140 is provided with a pressing channel 141, one end of the pressing channel 141 being communicated with the pressing opening 1111 of the connecting channel 111. The pressing member 120 is slidably arranged in the connecting channel 111 of the pressing seat 140 and is buckled with the pressing seat 140. The pressing part of the pressing member 120 is exposed at the end of the pressing seat 140 away from the connecting seat 110, so as to facilitate the staff to press the pressing member 120. The second elastic member 150 can be a spring. The second elastic member 150 is arranged in the pressing channel 141 of the pressing seat 140. The inner end of the second elastic member 150 abuts against the pressing seat 140, and the outer end abuts against the inner side of the pressing member 120. Thus, the second elastic member 150 is used to provide an outward reset force to the pressing member 120, so that the pressing member 120 is located or reset to the pressing position. When the pressing member 120 is at the pressing position, the pressing protrusion 121 of the pressing member 120 is in a separated state with the extending end 224 of the lock rod 220, and the elastic finger 122 is in a separated state with the first locking member 250.

[0052] Specifically, before the display module 400 is assembled to the box frame 300, the pressing member 120 is located at the pressing position under the action of the second elastic member 150. At this time, during the process of inserting the insertion part 211 into the connecting channel 111, the pressing protrusion 121 of the pressing member 120 does not interfere with the movement of the lock rod 220, and the finger end 1222 of the elastic finger 122 does not interfere with the movement of the first locking member 250, so as to ensure that the insertion part 211 can be smoothly inserted into the connecting channel 111, thereby facilitating the installation of the display module 400. After the display module 400 is separated from the box frame 300, the insertion part 211 is separated from the connecting channel 111, and the first locking member 250 is separated from the elastic finger 122. At this time, the elastic finger 122 is restored to the pressing position under the action of the second elastic member 150 without the restriction of the first locking member 250, so as to prepare for the next time to push the lock rod 220. It can be seen that the second elastic member 150 is arranged to facilitate the use of the pressing member 120.

[0053] Furthermore, when the fingertip 1222 of the elastic finger 122 abuts against the first locking member 250, the pressing member 120 abuts against the end of the locking rod 220. Specifically, during the disassembly process of the display module 400, in the locked state, refer to... Figure 4 and Figure 9 The pressing member 120 is in the pressing position. A raised pressing protrusion 121 is provided on the inner side of the pressing member 120. The pressing protrusion 121 is separated from the end of the locking rod 220. The elastic finger 122 is separated from the first locking member 250. The locking rod 220 is in the first position. The first locking member 250 abuts against the side wall of the locking rod 220. A large portion of the first locking member 250 is exposed on the surface of the insertion portion 211. During the first pressing stage, refer to... Figure 4 and Figure 10 The pressing member 120 is pressed and moves towards the insertion part 211. When the fingertip 1222 of the elastic finger 122 abuts against the side of the first locking member 250, the pressing protrusion 121 also abuts against the end of the locking rod 220. In the second pressing stage, refer to Figure 4 and Figure 11 The pressing member 120 is pressed to continue moving toward the insertion portion 211. The pressing protrusion 121 pushes the locking rod 220 to slide toward the guide channel 212. The elastic finger 122 elastically deforms outward and slides to the outermost part of the first locking member 250 to provide a force toward the first guide hole 213 to the first locking member 250. At this time, the first locking member 250 is located near the first clearance groove 221, but has not slid into the second positioning groove. In the third pressing stage, refer to Figure 4 and Figure 12 The pressing member 120 is pressed to continue moving toward the insertion part 211. At this time, the first locking member 250 slides relative to the elastic finger 122 along the length direction of the elastic finger 122. The pressing protrusion 121 continues to push the locking rod 220 to slide into the guide channel 212, and the locking rod 220 slides to the second position. At this time, the first clearance groove 221 coincides with the first guide hole 213. Under the action of the elastic finger 122, the first locking member 250 is inserted into the first clearance groove 221, thereby keeping the locking rod 220 in the second position to facilitate the disassembly of the display module 400.

[0054] Understandably, during the second pressing stage, as the elastic finger 122 undergoes elastic deformation, the pressing protrusion 121 of the pressing member 120 gradually pushes the locking rod 220 to slide into the guide channel 212. With this configuration, during the third pressing stage, the pressing member 120 only needs to push the locking rod 220 to slide a small distance, allowing the first clearance groove 221 and the first guide hole 213 to overlap, thereby enabling the locking rod 220 to engage with the insertion part 211, facilitating the disassembly of the display module 400.

[0055] In other possible embodiments, the pressing member 120 is in contact with the end of the lock rod 220 when the inner side of the elastic finger 122 is in contact with the outermost part of the first locking member 250. Specifically, in the first pressing stage, the pressing protrusion 121 is not in contact with the protruding end 224 of the lock rod 220 when the finger end 1222 of the elastic finger 122 is in contact with the first locking member 250; instead, in the second pressing stage, the pressing protrusion 121 is in contact with the protruding end 224 of the lock rod 220 when the elastic finger 122 slides to the outermost part of the first locking member 250.

[0056] In some embodiments, referring to Figure 4 and Figure 6 The finger end 1222 of the elastic finger 122 is provided with a guide slope 1223 for sliding against the first locking member 250. Specifically, in the first pressing stage, the finger end 1222 of the elastic finger 122 is in contact with the first locking member 250, and accordingly, the guide slope 1223 is in contact with the first locking member 250. In the second pressing stage, the pressing member 120 is pressed to continue moving in the direction of the insertion portion 211, and the first locking member 250 slides against the guide slope 1223, thereby pushing the elastic finger 122 to elastically deform outward, and further enabling the first locking member 250 to slide to the inner side of the elastic finger 122, or in other words, the elastic finger 122 slides to the outermost part of the first locking member 250 to provide the first locking member 250 with an elastic contact force in the direction of the first guide hole 213. It can be understood that, through the provision of the guide slope 1223, the first locking member 250 can smoothly spread the elastic finger 122 through the guide slope 1223 to slide into the inner side of the elastic finger 122 during the pressing of the pressing member 120, and thus, the pressing member 120 can be smoothly pressed into the pressing channel 141 to push the lock rod 220 to slide from the first position to the second position, thereby facilitating the disassembly of the display module 400.

[0057] In some embodiments, referring to Figure 4 and Figure 6The inner side of the elastic finger 122 is provided with a retaining groove 1221 along the length direction of the elastic finger 122, the retaining groove 1221 does not extend to the finger end 1222 of the elastic finger 122, the retaining groove 1221 is used for embedding the first locking piece 250, and the first locking piece 250 can slide in the retaining groove 1221. It can be understood that in the second pressing stage, when the elastic finger 122 is unfolded and slides to the outermost part of the first locking piece 250, the exposed part of the first locking piece 250 is embedded in the retaining groove 1221. In the third pressing stage, when the pressing piece 120 continues to move towards the plug-in part 211, the first locking piece 250 slides along the retaining groove 1221 relative to the elastic finger 122, so that the first guide hole 213 is coincided with the first displacement groove 221, and then the first locking piece 250 is embedded in the first displacement groove 221.

[0058] It can be understood that the elastic finger 122 is embedded in the retaining groove 1221, so that the first locking piece 250 can be prevented from being separated from the elastic finger 122 under the action of the second elastic piece 150. Thus, the inner side of the elastic finger 122 can be kept in abutment with the first locking piece 250, the elastic finger 122 keeps the first locking piece 250 embedded in the first displacement groove 221, so that the lock rod 220 keeps in the second position. In other words, under the limitation of the first locking piece 250, the lock rod 220 cannot be reset to the first position under the action of the first elastic piece 230, so that the retaining force of the plug-in part 211 and the connecting seat 110 is always released, and the display module 400 can be conveniently detached from the box frame 300.

[0059] In some embodiments, referring to Figure 4 and Figure 6The first locking members 250 and the elastic fingers 122 are provided in equal numbers, and the first locking members 250 are sequentially arranged on the circumferential side of the plug-in part 211 and correspond to the elastic fingers 122 one by one. Specifically, the plug-in part 211 is sequentially provided with a plurality of first guide holes 213 along the circumferential direction thereof, and the first locking members 250 are movably arranged in the first guide holes 213 one by one. Meanwhile, the elastic fingers 122 are provided in a plurality of numbers, and the plurality of elastic fingers 122 are arranged on the inner side of the pressing member 120 and sequentially located around the pressing protrusions 121, and the elastic fingers 122 are arranged one by one corresponding to the first locking members 250. It can be understood that when the lock rod 220 is in the second position, each elastic finger 122 abuts against the corresponding first locking member 250, so that each first locking member 250 is embedded in the first displacement slot 221, and therefore, the plurality of first locking members 250 cooperate to keep the lock rod 220 in the second position, and the lock rod 220 always releases the holding force of the plug-in part 211 and the connecting seat 110, so that the plug-in part 211 can be conveniently pulled out of the connecting channel 111, and the display module 400 can be conveniently disassembled from the box frame 300.

[0060] In order to facilitate the assembly of the first elastic member 230, in some specific embodiments, with reference to Figure 4 and Figure 5 The inner circumferential wall of the guide channel 212 is provided with a stepped surface 2121 facing the plug-in end 2111, the side of the lock rod 220 is provided with an annular groove 223, the annular groove 223 is sleeved and fixed with a fixing ring 240, and the fixing ring 240 is located between the stepped surface 2121 and the plug-in end 2111. The first elastic member 230 can adopt a spring, the first elastic member 230 is sleeved on the outer side of the lock rod 220, one end of the first elastic member 230 away from the plug-in end 2111 abuts against the stepped surface 2121, and the other end abuts against the fixing ring 240. Therefore, the first elastic member 230 is axially abutted between the lock rod 220 and the lock catch seat 210, and provides a spring force to the lock rod 220 towards the connecting seat 110 through the fixing ring 240, so that the lock rod 220 can be reset from the second position to the first position towards the connecting seat 110.

[0061] It can be understood that the first elastic member 230 adopts the above assembly mode, and the lock catch seat 210, the first elastic member 230 and the lock rod 220 can be conveniently assembled together, so that the lock catch assembly 200 is assembled as a whole, thereby facilitating the assembly of the lock catch assembly 200 to the bottom shell 410 of the display module 400; or the lock catch seat 210, the first elastic member 230 and the lock rod 220 are assembled as a whole, and the staff can conveniently disassemble the lock catch assembly 200 from the bottom shell 410 of the display module 400.

[0062] In other possible embodiments, the first elastic member 230 can be arranged at the bottom of the lock seat 210, one end of the first elastic member 230 abutting against the bottom shell 410 of the display module 400, and the other end abutting against the tail of the lock rod 220. Thus, the first elastic member 230 can provide an elastic force to the lock rod 220 towards the connecting seat 110, so that the lock rod 220 can be reset from the second position to the first position.

[0063] In some embodiments, referring to Figure 2 、 Figure 4 and Figure 5 , the side of the plug-in part 211 is provided with a second guide hole 214 communicating with the guide channel 212, and the lock assembly 200 further comprises a second locking member 260, which can be a ball but is not limited to a ball only, for example, the second locking member 260 can also be a rod-shaped body with rounded corners at both ends, and the second locking member 260 is movably arranged in the second guide hole 214; wherein the side wall of the lock rod 220 is provided with a second accommodation slot 222, when the lock rod 220 is in the first position, the second guide hole 214 is staggered with the second accommodation slot 222 (see Figure 9 ), the outer peripheral wall of the lock rod 220 abuts against the second locking member 260, so that the second locking member 260 has a lock part exposed outside the plug-in part 211, and the lock part is used for clamping with the connecting seat 110; when the lock rod 220 is in the second position, the second guide hole 214 coincides with the second accommodation slot 222 (see Figure 12 ), the second locking member 260 can move towards the second accommodation slot 222 to hide in the side of the plug-in part 211.

[0064] In a specific application, the lock seat 210 is connected to the bottom shell 410 of the display module 400, the lock rod 220 is in the first position under the action of the first elastic member 230, the second accommodation slot 222 on the lock rod 220 is staggered with the second guide hole 214 (see Figure 9 ), the outer peripheral wall of the lock rod 220 abuts against the side of the second locking member 260 close to the guide channel 212, thus, the second locking member 260 is partially exposed outside the plug-in part 211 under the limitation of the lock rod 220, so as to stably clamp with the inner side of the connecting channel 111, and further to stably assemble the display module 400 on the cabinet frame 300. If it is needed to disassemble the display module 400 from the cabinet frame 300, the pressing member 120 pushes the lock rod 220 to slide towards the guide channel 212 and to the second position, the second accommodation slot 222 on the side wall of the lock rod 220 coincides with the second guide hole 214, and the second locking member 260 can move towards the second accommodation slot 222 (see Figure 11), thus the lock rod 220 releases the restriction on the second locking member 260, the second locking member 260 can move towards the second displacement slot 222, the second locking member 260 is hidden in the side of the plug-in part 211, thereby releasing the axial restriction between the lock seat 210 and the fixed seat, the lock seat 210 and the fixed seat can be separated, so that the display module 400 can be conveniently disassembled from the box frame 300.

[0065] Instead of the above-mentioned lock part, in other possible embodiments, the plug-in part 211 is sequentially provided with a plurality of elastic arms (not shown in the figure) in the circumferential direction thereof, each of the elastic arms can be elastically deformed outwardly or inwardly, and the lock part is a protruding part provided on the outside of the elastic arm. The lock rod 220 is movably arranged between the elastic arms, and during the axial sliding of the lock rod 220 between the elastic arms, the lock rod 220 controls the expansion or contraction of the elastic arms, thereby controlling the outward protrusion or inward contraction of the lock part, so that the axial restriction between the plug-in part 211 and the lock seat 210 can be released.

[0066] In some embodiments, referring to Figure 7 With Figure 8 , the fixed assembly 100 further comprises an elastic energy storage member 160, the connecting seat 110 is rotatably arranged on the mounting base 130, and the elastic energy storage member 160 is connected with the mounting base 130 and the connecting seat 110, for storing energy when the connecting seat 110 rotates circumferentially. Wherein, the plug-in part 211 is provided with a retractable lock part, which can be understood as the exposed part of the second locking member 260, and the inner circumferential wall of the connecting channel 111 is provided with a circumferentially extending and oppositely directed guide groove 1113 and a locking groove 1114 (refer to Figure 13 ), one end of the guide groove 1113 is connected with the plug-in port 1112, the other end extends towards the outlet and is connected with the locking groove 1114. When the lock part slides along the guide groove 1113, the connecting seat 110 is adapted to rotate in a circumferential direction to make the elastic energy storage member 160 store energy; when the lock part moves to the locking groove 1114, the elastic energy storage member 160 drives the connecting seat 110 to rotate in the other circumferential direction to make the lock part slide into the locking groove 1114.

[0067] Wherein, the guide groove 1113 is spirally arranged on the inner circumferential wall of the connecting channel 111, and the spiral angle of the guide groove 1113 is less than or equal to 15 degrees; or, the guide groove 1113 is circumferentially inclinedly arranged on the inner circumferential wall of the connecting channel 111; and, the locking groove 1114 is spirally arranged on the inner circumferential wall of the connecting channel 111, and the spiral angle of the guide groove 1113 is greater than or equal to 20 degrees.

[0068] Specifically, during the assembling process of the display module 400 and the cabinet frame 300, the locking portion is aligned with the guide groove 1113 and located at the port of the insertion port 1112, the insertion portion 211 extends into the connecting channel 111 from the insertion port 1112, the locking portion slides along the guide groove 1113 into the locking groove 1114 and is kept in the locking groove 1114, so as to assemble and connect the locking seat 210 to the fixing assembly 100, and then conveniently assemble the display module 400 to the cabinet frame 300. During the process of inserting the insertion portion 211 into the connecting channel 111, since the guide groove 1113 extends circumferentially during the process of extending from the insertion port 1112 to the other end of the connecting channel 111, the locking portion drives the connecting seat 110 to rotate forward during the process of sliding along the guide groove 1113, the connecting seat 110 pulls the elastic energy storage member 160 to be elongated in the forward direction, and the elastic energy storage member 160 is effectively stored. When the locking portion moves to the position of the locking groove 1114, the elastic energy storage member 160 starts to release the force to provide the connecting seat 110 with a circumferential force in the reverse direction, so that the connecting seat 110 reversely rotates under the drive of the elastic energy storage member 160, so as to make the locking portion slide into the locking groove 1114, and then realize the fixed assembly and connection of the locking seat 210 to the mounting base 130, and correspondingly, the assembly of the display module 400 to the cabinet frame 300.

[0069] It should be emphasized that the locking groove 1114 needs to lock the locking portion, and the locking groove 1114 needs to extend less or not extend axially when extending circumferentially, so as to lock the locking portion. The present application effectively realizes that the locking portion can slide into the locking groove 1114 by the setting of the elastic energy storage member 160, and after the elastic energy storage member 160 releases the force, the elastic energy storage member 160 keeps the position of the connecting seat 110 to limit the rotation of the connecting seat 110, so as to keep the locking portion in the locking groove 1114, thereby stably assembling the locking seat 210 to the fixing assembly 100.

[0070] In other possible embodiments, a limiting convex ring (not shown in the figure) is arranged on the inner side of the connecting channel 111 close to the insertion port 1112, and the limiting convex ring can also connect the locking seat 210 and the connecting seat 110 by limiting the locking portion, so as to assemble the display module 400 to the cabinet frame 300.

[0071] In order to facilitate the installation of the elastic energy storage member 160, in some embodiments, the elastic energy storage member 160 is arranged on the connecting seat 110. Figure 7 In order to facilitate the installation of the elastic energy storage member 160, in some embodiments, the elastic energy storage member 160 is arranged on the connecting seat 110. Figure 8The mounting base 130 is provided with a baffle part 131 and an end cover part 132, and the baffle part 131 is connected to the periphery of the end cover part 132. The connecting seat 110 is rotatably arranged at the center of the end cover part 132, and an annular surrounding space is formed between the outer periphery of the connecting seat 110 and the inner periphery of the baffle part 131. Meanwhile, the bottom of the connecting seat 110 is provided with a flange part 112 which is expanded to the periphery, and the flange part 112 is arranged corresponding to the end cover part 132. The inner side of the end cover part 132 is provided with a first latch 1321 which extends towards the flange part 112, and the inner side of the flange part 112 is provided with a second latch 113 which extends towards the end cover part 132. The first latch 1321 and the second latch 113 are arranged in the circumferential direction of the surrounding space. The elastic energy storage member 160 can be a tension spring, and the elastic energy storage member 160 is arranged in an arc shape in the surrounding space. One end of the elastic energy storage member 160 is hooked on the first latch 1321, and the other end is hooked on the second latch 113. Thus, the elastic energy storage member 160 is conveniently connected to the periphery between the mounting base 130 and the connecting seat 110, so that the elastic energy storage member 160 can effectively store energy when the connecting seat 110 rotates.

[0072] The application also discloses a display device, which refers to Figure 4 and Figure 14 , comprising a cabinet frame 300, a display module 400 and the above-mentioned connecting lock buckle. The connecting seat 110 is connected to the cabinet frame 300, and the lock buckle seat 210 is assembled or integrally connected with the bottom shell 410 of the display module 400.

[0073] In the specific application process, when the display module 400 is assembled on the cabinet frame 300, the pressing member 120 does not push the lock rod 220 to move, and the lock rod 220 remains in the first position under the action of the first elastic member 230. At this time, the lock rod 220 keeps the insertion part 211 clamped with the lock buckle seat 210, so as to ensure that the display module 400 is stably assembled on the cabinet frame 300. When it is needed to disassemble the display module 400 from the cabinet frame 300, the worker presses the pressing member 120, and the pressing member 120 pushes the lock rod 220 to shrink towards the direction of the guide channel 212. The lock rod 220 slides from the first position to the second position. At this time, the lock rod 220 releases the holding force of the insertion part 211 clamped with the connecting seat 110, and the insertion part 211 can be conveniently pulled out from the connecting channel 111, so that the display module 400 can be conveniently disassembled from the cabinet frame 300.

[0074] It should be noted that when the pressing piece 120 is pressed, the finger end 1222 of the elastic finger 122 abuts against the first locking piece 250, and as the pressing piece 120 continuously approaches the plug-in part 211, the elastic finger 122 gradually spreads outward until sliding to the outermost part of the first locking piece 250. At the same time, when the locking rod 220 slides to the second position, the first displacement slot 221 is coincided with the first guide hole 213, and the elastic finger 122 abuts against the exposed part of the first locking piece 250 (refer to Figure 11 With Figure 12 ), therefore, the side part of the first locking piece 250 is embedded into the first displacement slot 221 under the action of the elastic finger 122, so as to make the locking rod 220 clamped with the plug-in part 211, and further make the locking rod 220 kept in the second position relative to the plug-in part 211, correspondingly, the locking rod 220 releases the holding force of the plug-in part 211 clamped with the connecting seat 110. When the display module 400 is detached from the box frame 300, the locking rod 220 is effectively prevented from resetting to the first position under the action of the first elastic piece 230, so that the locking rod 220 does not have the holding force of making the plug-in part 211 clamped with the connecting seat 110, and the display module 400 is more convenient to detach.

[0075] The technical means disclosed in the present application is not limited to the technical means disclosed in the above-mentioned embodiments, and also includes the technical solutions composed of any combination of the above technical features. It should be noted that for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements are also considered to be within the scope of protection of the present application.
