In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0041] See also Figures 1 to 3 , is a connection mechanism provided by an embodiment of the present invention, the locking mechanism is applied to a display device (refer to Fig.10 and Fig.11 ), and the application of the display device is used as an example for explanation, but it is not limited to the display device. The locking mechanism includes a locking component 100 and a fixing component 200, the fixing component 200 is fixed to the box frame 400 of the display device, the locking component 100 is connected to the bottom shell 310 of the display module 300 of the display device, and the locking component 100 is connected to the fixing component 200, so that the display module 300 is assembled on the box frame 400.

[0042] The lock assembly 100 includes a lock seat 110, a lock rod 120 and a first elastic member 130. The lock seat 110 is assembled or integrally connected to the bottom shell 310 of the display module 300. The lock seat 110 is provided with a protruding plug-in portion 112, the plug-in portion 112 is provided with a plug-in end, and a lock portion 113 is provided on the side of the plug-in portion 112. The lock rod 120 is slidably disposed on the inner side of the plug-in portion 112 along the axial direction of the plug-in portion 112, and extends from the plug-in end 1123 of the plug-in portion 112. The first elastic member 130 is disposed on the lock seat 110, and is used to provide an elastic force to the lock rod 120 toward the plug-in end 1123 of the plug-in portion 112.

[0043] The fixing assembly 200 includes a connecting seat 210 and a knob 220. The connecting seat is connected to the box frame 400. The connecting seat 210 is provided with a fixing channel 211. The fixing channel 211 forms an insertion port 2111 and an extension port 2112 at both ends of the connecting seat 210. The insertion port 2111 is located at the front side of the box frame 400, and the extension port 2112 is located at the back side of the box frame 400. When the locking seat 110 is assembled with the connecting seat 210, the plug-in portion 112 extends into the fixing channel 211 through the plug-in port 2111, and the locking portion 113 is engaged with the connecting seat 210. The knob 220 is rotatably connected to one end of the connecting seat 210 away from the locking seat 110, and the inner side of the knob 220 conflicts with the extension end of the locking rod 120; wherein, when the knob 220 is rotated, it pushes the locking rod 120 to shrink toward the plug-in portion 112 to release the holding force of the locking rod 120 on the locking portion 113.

[0044] In specific application, when the display module 300 is assembled on the box frame 400, the first elastic member 130 makes the locking rod 120 extend toward the direction of the knob 220. At this time, the locking rod 120 maintains the position of the locking portion 113, so that the plug-in portion 112 and the connecting seat 210 remain in a clamping state, thereby ensuring that the display module 300 is firmly assembled on the box frame 400 at its rear side. When it is necessary to release the axial restriction between the plug-in portion 112 and the connecting seat 210, the staff rotates the knob 220 circumferentially, and the knob 220 pushes the locking rod 120 to shrink toward the plug-in portion 112 during the rotation process. The locking rod 120 releases the holding force of the locking portion 113 toward the inner peripheral wall of the fixing channel 211, thereby releasing the axial restriction between the plug-in portion 112 and the connecting seat 210, and the plug-in portion 112 can be easily withdrawn from the fixing channel 211, and then the display module 300 can be easily removed from the box frame 400 for maintenance.

[0045] It should be noted that the locking rod 120 is in contact with the knob 220 , and when the plug-in portion 112 is pulled out of the fixing channel 211 , the locking rod 120 can be separated from the connecting seat 210 along with the plug-in portion 112 , thereby ensuring that the display module 300 can be normally disassembled.

[0046] In some embodiments, reference Figures 2 to 4The fixing assembly 200 also includes a mounting base 230, which is assembled and connected or integrated with the box frame 400, and one end of the connecting seat 210 is integrated or assembled with the mounting base 230. When the connecting seat 210 is assembled on the mounting base 230, the two can be fixedly assembled and connected, or can be rotatably assembled and connected. The specific setting is based on actual needs. This application takes the rotational assembly as an example for explanation. The mounting base 230 is provided with a first guide groove 234 located in the circumferential direction of the connecting seat 210. The first guide groove 234 is spirally arranged, or the first guide groove 234 is circumferentially inclined. The knob 220 is provided with a knob 224, and the knob 224 is rotatably arranged in the first guide groove 234. One or more first guide grooves 234 can be provided. If a plurality of first guide grooves 234 are provided, the first guide grooves 234 are located around the connecting seat 210. As shown in the attached drawings, two first guide grooves 234 are provided and located at two opposite positions of the mounting base 230. Correspondingly, the knob 220 is provided with a screw-on portion 224 at two opposite positions. The two screw-on portions 224 are rotatably disposed in the two first guide grooves 234 respectively, so that the knob 220 is rotatably disposed on the mounting base 230.

[0047] Specifically, the knob 220 works during the rotation process, and the knob portion 224 moves circumferentially along the first guide groove 234. During the circumferential movement of the knob portion 224 along the first guide groove 234, the first guide groove 234 causes the knob portion 224 to move toward the lock seat 110, thereby driving the knob 220 to move toward the lock seat 110, and the inner side of the lock seat 110 pushes the locking rod 120 to shrink toward the inner side of the plug-in portion 112, and the locking rod 120 releases the retention force of the locking rod 113 toward the inner peripheral wall of the fixing channel 211, thereby releasing the axial restriction between the plug-in portion 112 and the connecting seat 210, so as to facilitate the disassembly of the display module 300. It can be understood that the mounting base 230 is provided with the first guide groove 234 so that the knob 220 can push the locking rod 120 to retract in the direction of the plug-in portion 112 during the rotation process. With this arrangement, the connection structure between the knob 220 and the mounting base 230 is simple, the manufacturing difficulty and the assembly difficulty are also low, and it is suitable for mass production.

[0048] In other possible embodiments, the knob 220 is provided with a circumferentially extending arc-shaped protrusion at the position where the locking rod 120 abuts, and the locking rod 120 is provided with a circumferentially extending arc-shaped groove (not shown in the figure) at the end of the locking rod 120 close to the knob 220. During the circumferential rotation of the knob 220, the arc-shaped protrusion cooperates with the arc-shaped groove, and the inner side of the knob 220 can also push the locking rod 120 to contract toward the plug-in portion 112, and the knob 220 itself remains stationary in the axial direction.

[0049] In some specific embodiments, referring to Figure 2 , Figure 4 and Figure 5 The mounting base 230 is provided with a guide circumferential surface 233 facing the bottom of the lock seat 110, and the guide circumferential surface 233 is located around the connecting seat 210. The first guide groove 234 is provided on the outer peripheral side of the mounting base 230 and is located on the guide circumferential surface 233 of the mounting base 230, or in other words, the first guide groove 234 is provided on the guide circumferential surface 233 and passes through the outer peripheral side of the mounting base 230. Of course, the first guide groove 234 can also be provided only on the outer peripheral side of the connecting seat 210 and not located on the guide circumferential surface 233.

[0050] Meanwhile, the knob 220 includes a bottom cover 221 and a rotating ring 222. The rotating ring 222 is connected to the periphery of the bottom cover 221. The outer peripheral side of the rotating ring 222 is provided with anti-slip grooves to facilitate the rotation of the knob 220. Lugs 223 are respectively provided at two opposite positions on the edge of the rotating ring 222. The lugs 223 of the rotating buckle 224 are provided on the inner peripheral side of the lugs 223 and are provided in a rod-shaped body. Specifically, when the knob 220 is assembled on the bottom of the mounting base 230 away from the locking seat 110, the protruding end of the locking rod 120 abuts against the inner side of the bottom cover 221, the rotating ring 222 is provided around the mounting base 230, and the two rotating buckles 224 are respectively embedded in the first guide grooves 234 and slide along the first guide grooves 234. Among them, a guide slope 2241 is provided at the inner end of the turn button portion 224 and on the side away from the bottom cover portion 221. When the knob 220 is assembled on the mounting base 230, the guide slope 2241 can be used to push the lug 223 to elastically deform outward on the surrounding side of the mounting base 230, so that the turn button portion 224 can pass over the surrounding side of the mounting base 230 to be embedded in the first guide groove 234.

[0051] It is understandable that the first guide groove 234 is configured as the above-mentioned structural form, the connection structure between the knob 220 and the mounting base 230 is simple, and the knob 220 can be easily assembled on the mounting base 230, thereby facilitating the production of the connection structure.

[0052] In some embodiments, reference Figures 3 to 5 The fixing assembly 200 also includes a second elastic member 250, which is connected to the mounting base 230 and the knob 220, and is used to restore the knob 220 to its starting position when it is not rotated. As a result, the knob 220 moves away from the plug-in portion 112 under the action of the second elastic member 250 to prepare for the next push of the locking rod 120.

[0053] In order to facilitate the assembly of the second elastic member 250, a retaining seat 240 is provided at the bottom of the mounting base 230 near the knob 220, and a clearance hole 241 is provided at the center of the retaining seat 240. An annular convex edge 225 is provided on the inner side of the bottom cover 221, and the annular convex edge 225 is rotatably penetrated in the clearance hole 241, so that the knob 220 is rotatably set on the retaining seat 240, and then rotatably set on the mounting base 230. At the same time, the clearance hole 241 is used to make way for the extended end of the locking rod 120, so that the extended end of the locking rod 120 can be abutted against the inner side of the knob 220. Among them, a first latch 235 extending toward the bottom cover 221 is provided at the bottom of the mounting base 230 near the bottom cover 221, and a second latch 226 extending toward the mounting base 230 is provided on the inner side of the bottom cover 221, and the first latch 235 and the second latch 226 are spaced apart in the circumferential direction of the outer side of the retaining seat 240. The second elastic member 250 can be a tension spring. The second elastic member 250 is disposed between the outer circumference of the retaining seat 240 and the inner circumference of the rotating ring portion 222. One end of the second elastic member 250 is hooked on the first latch 235, and the other end is hooked on the second latch 226 (see Figure 6 ), whereby the second elastic member 250 is connected between the knob 220 and the mounting base 230 to provide the knob 220 with a rotational force in a circumferential direction.

[0054] Specifically, during the forward rotation of the knob 220, the first latch 235 and the second latch 226 move away from each other in the circumferential direction, the second elastic member 250 is stretched, the knob 224 moves circumferentially along the first guide groove 234, and drives the knob 220 to move toward the extension opening 2112, so as to push the lock bar 120 to shrink toward the inner side of the plug-in portion 112. When the display module 300 is completely disassembled, the plug-in portion 112 is separated from the fixed channel 211, and the knob 220 rotates in the opposite direction under the action of the second elastic member 250, and the knob 224 returns to the starting position of the first guide groove 234 along the first guide groove 234, and moves the knob 220 away from the extension opening 2112, so as to prepare for the next push of the lock bar 120. It can be seen that the provision of the second elastic member 250 facilitates the reuse of the knob 220.

[0055] In order to keep the knob 220 in the rotated position, in a further specific embodiment, Figures 3 to 5 The lock seat 110 and the knob 220 can be circumferentially engaged with each other so that the knob 220 can remain in the unlocked position after rotation; wherein, when the knob 220 is in the unlocked position, the lock rod 120 releases the retaining force of the lock portion 113 toward the inner wall of the fixed channel 211, or in other words, when the staff is operating the knob 220 and rotating it, when the knob 220 completes the pushing of the lock rod 120, the position of the knob 220 can be understood as the unlocked position.

[0056] It can be understood that when the knob 220 is in the unlocked position, since the knob 220 is circumferentially engaged with the lock seat 110, the knob 220 will not return to its original position when it is not rotated under the action of the second elastic member 250. Therefore, the inner side of the knob 220 keeps the lock rod 120 in a compressed state, so that the lock rod 120 remains in an unrestricted state with respect to the lock portion 113, thereby facilitating the removal of the plug-in portion 112 from the fixed channel 211, and the display module 300 can be easily removed from the box frame 400 for maintenance; at the same time, when the display module 300 is disassembled from the box frame 400, the lock seat 110 and the knob 220 are also separated, and the lock seat 110 releases the restriction on the knob 220. The knob 220 is reset to its original position when it is not rotated under the action of the second elastic member 250, so as to prepare for the next push of the lock rod 120.

[0057] Further, refer to Figure 1 , Figure 4 and Figure 5 The locking seat 110 is also provided with a mounting bottom 111 connected to the plug-in portion 112, and the mounting bottom 111 is used for assembly connection or integration connection with the bottom shell 310 of the display module 300 (refer to Fig.10 and Fig.11 ). The first elastic member 130 is disposed on the inner side of the mounting bottom 111, one end of the first elastic member 130 abuts against the bottom shell 310 of the display module 300, and the other end abuts against the inner end of the locking rod 120, thereby providing an elastic force toward the insertion end 1123 to the locking rod 120. The mounting bottom 111 is provided with a connecting arm 1111 extending toward the knob 220, and a buckle portion 2231 is provided on the outer side of the lug 223. The connecting arm 1111 is located on the circumferential motion path of the buckle portion 2231, and the buckle portion 2231 is used to be buckled with the connecting portion to maintain the position of the knob 220 after rotation.

[0058] Specifically, when the knob 220 rotates in the circumferential direction, the connecting arm 1111 is elastically deformed outward, or the lug 223 is elastically deformed inward, or the two are deformed to avoid each other, and the buckle portion 2231 passes over the inner side of the connecting arm 1111. After the buckle portion 2231 passes over the connecting arm 1111, the connecting arm 1111 returns to its previous shape. At this time, the connecting arm 1111 limits the resetting movement of the buckle portion 2231, and the buckle portion 2231 is circumferentially abutted against the connecting arm 1111 under the action of the second elastic member 250, so that the knob 220 is kept in the unlocked position, and then the knob 220 maintains the compression force on the lock rod 120, thereby, the plug-in portion 112 and the connecting seat 210 are kept in the unlocked state, so as to facilitate the disassembly of the display module 300.

[0059] In some embodiments, reference Figures 3 to 5The connecting seat 210 is rotatably arranged on the mounting base 230, and the fixing assembly 200 further includes an elastic energy storage member 260, which is connected to the mounting base 230 and the connecting seat 210 and is used to store energy when the connecting seat 210 rotates circumferentially. The inner peripheral wall of the fixing channel 211 is provided with a second guide groove 2113 and a locking groove 2114 extending circumferentially and facing opposite directions (refer to Figure 7 ), one end of the second guide groove 2113 is connected to the insertion port 2111, and the other end extends toward the extension port 2112 and is connected to the locking groove 2114. When the locking portion 113 slides along the second guide groove 2113, the connecting seat 210 is adapted to rotate along a circumferential direction of the movement of the locking portion 113, so that the elastic energy storage member 260 stores energy; when the locking portion 113 moves to the locking groove 2114, the elastic energy storage member 260 drives the connecting seat 210 to rotate along another circumferential direction, so that the locking portion 113 slides into the locking groove 2114.

[0060] Specifically, during the assembly process of the display module 300 and the box frame 400, the locking portion 113 is aligned with the end of the second guide groove 2113 located at the plug interface 2111, the plug-in portion 112 extends from the plug interface 2111 into the fixing channel 211, and the locking portion 113 slides into the locking groove 2114 along the second guide groove 2113 and is retained in the locking groove 2114, thereby assembling the locking seat 110 to the fixing component 200, thereby conveniently assembling the display module 300 on the box frame 400. In the process of inserting the plug-in portion 112 into the fixed channel 211, since the second guide groove 2113 is extended from the plug-in port 2111 toward the other end of the fixed channel 211, the second guide groove 2113 is also extended circumferentially, so the lock portion 113 drives the connection seat 210 to rotate in the positive direction during the sliding process along the second guide groove 2113, and the connection seat 210 pulls the elastic energy storage member 260 to be stretched in the positive direction, and the elastic energy storage member 260 is effectively stored. When the lock portion 113 moves to the position of the locking groove 2114, the elastic energy storage member 260 begins to release force to provide a circumferential force in the reverse direction to the connection seat 210, thereby, the connection seat 210 rotates in the reverse direction under the drive of the elastic energy storage member 260, so that the lock portion 113 slides into the locking groove 2114, and then the lock seat 110 is fixedly assembled and connected to the mounting base 230, and accordingly, the display module 300 is assembled on the box frame 400.

[0061] It should be emphasized that the locking groove 2114 needs to lock the locking portion 113. When the locking groove 2114 extends circumferentially, the locking groove 2114 has a small axial extension or does not extend axially, so that the locking groove 2114 can lock the locking portion 113. The present application effectively realizes that the locking portion 113 can slide into the locking groove 2114 through the provision of the elastic energy storage member 260; and after the elastic energy storage member 260 releases the force, the elastic energy storage member 260 maintains the position of the connecting seat 210 to limit the rotation of the connecting seat 210, so that the locking portion 113 remains in the locking groove 2114, thereby, the locking seat 110 is stably assembled on the fixing assembly 200.

[0062] In other possible embodiments, a limiting protrusion is provided on the inner side of the fixing channel 211 near the plug-in port 2111 . The limiting protrusion can also connect the locking seat 110 with the connecting seat 210 by restricting the locking portion 113 , thereby assembling the display module 300 on the box frame 400 .

[0063] Instead of the above-mentioned arrangement of the locking portion 113, in other possible embodiments, the side of the plug-in portion 112 is provided with a guide hole 1122 connected to the movable channel 1121 along its radial direction, and the locking portion 113 is a ball movably arranged in the guide hole 1122, and the inner side of the ball is in conflict with the locking rod 120. Specifically, during the axial sliding process or circumferential rotation process of the locking rod 120 in the movable channel 1121, the side wall of the locking rod 120 acts on the inner side of the ball, so that the ball bulges outward, and then the locking portion 113 remains embedded in the locking groove 2114. When the side wall of the locking rod 120 releases the force on the ball, the ball can shrink toward the movable channel 1121, thereby releasing the axial restriction between the plug-in portion 112 and the connecting seat 210, and then the display module 300 can be easily removed from the box frame 400.

[0064] In some specific embodiments, the second guide groove 2113 is spirally disposed on the inner peripheral wall of the fixed channel 211 (see Figure 7 ), the spiral angle of the second guide groove 2113 is less than or equal to 15 degrees. With this arrangement, the spiral angle of the second guide groove 2113 is smaller than its self-locking angle. In other words, during the circumferential extension of the second guide groove 2113, the second guide groove 2113 extends a greater length in the axial direction of the fixed channel 211. With this arrangement, when the staff pushes the locking portion 113 to slide along the second guide groove 2113, the locking portion 113 can drive the connecting seat 210 to rotate, thereby allowing the elastic energy storage member 260 to effectively store force for subsequent driving the connecting seat 210 to rotate.

[0065] In some embodiments, the locking groove 2114 is spirally disposed on the inner wall of the fixing channel 211 (see Figure 7), the spiral angle of the locking groove 2114 is greater than or equal to 20 degrees. With this arrangement, the spiral angle of the locking groove 2114 is greater than or equal to its self-locking angle. In other words, during the circumferential extension of the locking groove 2114, the locking groove 2114 has a smaller extension length along the length direction of the fixed channel 211. With this arrangement, after the locking portion 113 slides into the locking groove 2114, the locking portion 113 can be retained in the locking groove 2114 and will not slide into the second guide groove 2113, so that the locking seat 110 can be firmly assembled on the fixing component 200, thereby ensuring that the display module 300 is firmly assembled on the box frame 400.

[0066] It should be noted that the locking groove 2114 is arranged in a spiral shape. When the elastic energy storage member 260 drives the connecting seat 210 to rotate, the connecting seat 210 pulls the locking seat 110 toward the fixing component 200 through the locking portion 113, thereby reducing the gap between the display module 300 and the box frame 400, thereby ensuring the flatness of the display module 300.

[0067] In order to facilitate the installation of the elastic energy storage member 260, in some embodiments, refer to Figures 3 to 5 The mounting base 230 is provided with a panel portion 231 and an end cover portion 232, and the panel portion 231 is connected to the periphery of the end cover portion 232. The connecting seat 210 is rotatably arranged in the center of the end cover portion 232, and a circular enclosed space is formed between the outer circumference of the connecting seat 210 and the inner circumference of the panel portion 231; at the same time, the bottom of the connecting seat 210 is provided with a flange portion 212 that expands to the periphery, and the flange portion 212 is arranged corresponding to the end cover portion 232. Among them, the inner side of the end cover portion 232 is provided with a third latch 236 extending toward the flange portion 212, and the inner side of the flange portion 212 is provided with a fourth latch 213 extending toward the end cover portion 232, and the third latch 236 and the fourth latch 213 are arranged at intervals in the circumferential direction of the enclosed space. The elastic energy storage member 260 can be a tension spring. The elastic energy storage member 260 is arranged in an arc shape in the enclosed space. One end of the elastic energy storage member 260 is hooked on the third pin 236, and the other end is hooked on the fourth pin 213. Thus, the elastic energy storage member 260 is conveniently connected to the peripheral side between the mounting base 230 and the connecting base 210, so that it can effectively store force when the connecting base 210 rotates.

[0068] In a specific embodiment, referring to Figure 3 and Figure 8The plug-in portion 112 is provided with a guide channel along its axial direction, and the guide channel passes through the plug-in end 1123 of the plug-in portion 112. The lock rod 120 is slidably arranged in the guide channel, and one end of the lock rod 120 extends into the fixed channel 211 through the plug-in end 1123 to interfere with the knob 220. A guide hole 1122 is provided on the side of the plug-in portion 112, and the lock portion 113 is a ball disposed in the guide hole 1122. At the same time, an annular clearance groove 121 is provided on the side of the lock rod 120, and the clearance groove 121 is used to make way for the lock portion 113, and the lock portion 113 can move toward the clearance groove 121 so as to be hidden in the side of the plug-in portion 112. Among them, when the first elastic member 130 causes the clearance groove 121 of the locking rod 120 to be staggered with the locking portion 113, the side wall of the locking rod 120 causes the locking portion 113 to be partially exposed on the side of the plug-in portion 112, and the locking portion 113 can slide into the locking groove 2114 along the second guide groove 2113, so that the locking seat 110 is firmly connected to the connecting seat 210; when the knob 220 pushes the clearance groove 121 of the locking rod 120 to overlap with the locking portion 113, the locking portion 113 can move toward the clearance groove 121 to be hidden in the side of the connecting seat 210.

[0069] In specific applications, under the action of the first elastic member 130, the give way groove 121 on the locking rod 120 is staggered with the guide hole 1122, that is, the outer peripheral wall of the locking rod 120 and the side of the locking portion 113 close to the guide channel are abutted. Therefore, under the restriction of the locking rod 120, the locking portion 113 is partially exposed to the outside of the plug-in portion 112, so as to be firmly connected with the inner side of the fixing channel 211, thereby making the display module 300 firmly assembled on the box frame 400. If it is necessary to remove the display module 300 from the box frame 400, the knob 220 pushes the locking rod 120 to slide into the guide channel, and the clearance groove 121 on the side wall of the locking rod 120 coincides with the guide hole 1122, and the locking portion 113 can move toward the clearance groove 121. As a result, the locking rod 120 releases the restriction on the locking portion 113, and the locking portion 113 can move toward the clearance groove 121. The locking portion 113 is hidden in the side of the plug-in portion 112, thereby releasing the axial restriction between the locking seat 110 and the mounting base 230, and the locking seat 110 and the mounting base 230 can be separated, so that the display module 300 can be easily removed from the box frame 400.

[0070] Instead of the above-mentioned locking portion 113, in a possible embodiment, referring to Figures 3 to 9The plug-in portion 112 is provided with a plurality of elastic arms 1124 in sequence in the circumferential direction thereof, each elastic arm 1124 being capable of elastically deforming outward or inward, and the locking portion 113 being a protrusion provided on the outside of the elastic arm 1124. The locking rod 120 is movably provided between the elastic arms 1124, and during the axial sliding process of the locking rod 120 between the elastic arms 1124, the locking rod 120 controls the elastic arms 1124 to expand or contract, thereby controlling the locking portion 113 to protrude outward or contract inward.

[0071] In order to enable the locking rod 120 to control the elastic arm 1124 to elastically contract, in a specific embodiment, an inner convex portion 1125 is provided on the inner side of the end of the elastic arm 1124, and the locking rod 120 is provided with an outer convex portion 122. When the side wall of the outer convex portion 122 abuts against the inner side of the inner convex portion 1125, the elastic arm 1124 is in an outwardly expanded state, and the locking portion 113 is in an outwardly convex state, so as to be embedded in the locking groove 2114, so as to axially limit the plug-in portion 112 and the connecting seat 210, thereby ensuring that the display module 300 is firmly assembled on the box frame 400. When the outer protrusion 122 is staggered with the inner protrusion 1125, the elastic arm 1124 can be elastically deformed inward, so that the locking portion 113 can be in a contracted state. Therefore, the locking portion 113 can radially disengage from the locking groove 2114, thereby releasing the axial restriction between the plug-in portion 112 and the connecting seat 210, and the plug-in portion 112 can be easily pulled out from the fixing channel 211, so that the display module 300 can be easily removed from the box frame 400.

[0072] The present application also discloses a display device, referring to Figure 1 , Figure 3 , Fig.10 and Fig.11 , including a box frame 400, a display module 300 and the above-mentioned connection structure, wherein the connecting seat 210 is connected to the box frame 400, and the locking seat 110 is assembled and connected or integrated with the bottom shell 310 of the display module 300.

[0073] It is understandable that when the display module 300 is assembled on the box frame 400, the first elastic member 130 makes the locking rod 120 in the direction of the knob 220 in an extended state. At this time, the locking rod 120 maintains the position of the locking portion 113, so that the plug-in portion 112 and the connecting seat 210 remain in a clamping state, thereby ensuring that the display module 300 is firmly assembled on the box frame 400 at its rear side. When it is necessary to release the axial restriction between the plug-in portion 112 and the connecting seat 210, the staff rotates the knob 220 circumferentially, and the knob 220 pushes the locking rod 120 to shrink in the direction of the plug-in portion 112 during the rotation process. The locking rod 120 releases the holding force of the locking portion 113 toward the inner peripheral wall of the fixing channel 211, thereby releasing the axial restriction between the plug-in portion 112 and the connecting seat 210, and the plug-in portion 112 can be easily withdrawn from the fixing channel 211, and then the display module 300 can be easily removed from the box frame 400 for maintenance.

[0074] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above-mentioned technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
