[0045] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0046] See also Figures 1 to 4 , is a connection lock buckle provided in an embodiment of the present invention. Please refer to FIG. 1 to FIG. 1 , which is a connection lock buckle provided in an embodiment of the present invention. The connection lock buckle is applied to a display device, and is described by taking the application of the display device as an example, but is not limited to being used only for the display device (refer to Fig.14 The connecting lock includes a fixing component 100 and a locking component 200. The fixing component 100 is connected to the box frame 300 of the display device, and the locking component 200 is connected to the bottom shell 410 of the display module 400 of the display device. The locking component 200 is connected to the fixing component 100, so that the display module 400 is assembled on the box frame 300.

[0047] Specifically, refer to Figure 5 and Figure 6The fixing assembly 100 includes a connecting seat 110 and a pressing member 120. The connecting seat 110 is provided with a connecting channel 111. The connecting channel 111 forms a pressing port 1111 and an inserting port 1112 at both ends of the connecting seat 110 respectively. The pressing member 120 is arranged at the pressing port 1111. The pressing member 120 is provided with an elastic finger 122 for providing a retaining force. The lock assembly 200 includes a lock seat 210, a lock rod 220, a first locking member 250 and a first elastic member 230. The lock seat 210 is provided with a plug-in portion 211, the plug-in portion 211 extends into the connecting channel 111 through the plug-in port 1112, and is inserted into the pressing member 120 from the pressing port 1111. The plug-in portion 211 is provided with a guide channel 212 that passes through the plug-in end 2111 of the plug-in portion 211. The lock rod 220 is slidably arranged in the guide channel 212. The side of the plug-in portion 211 is provided with a first guide hole 213 that is connected to the guide channel 212. The first locking member 250 is movably arranged in the first guide hole 213. The side of the lock rod 220 is provided with a first give way groove 221. The first elastic member 230 is used to move toward the plug-in portion 211. The insertion direction acts on the locking rod 220 to separate the first clearance groove 221 from the first locking member 250; wherein the pressing member 120 is configured to be pressed to push the locking rod 220 to slide from the first position to the second position, when the locking rod 220 is in the first position, the first locking member 250 is staggered with the first clearance groove 221, and the locking rod 220 keeps the plug-in portion 211 and the connecting seat 110 engaged; when the locking rod 220 is in the second position, the first locking member 250 coincides with the first clearance groove 221, and the elastic finger 122 abuts against the exposed portion of the first locking member 250, so that the first locking member 250 remains embedded in the first clearance groove 221, and the locking rod 220 releases the retaining force of the plug-in portion 211 and the connecting seat 110.

[0048] The first locking member 250 may be a ball, but is not limited to a ball. For example, the first locking member 250 may also be a rod with rounded corners at both ends.

[0049] In a specific application process, when the display module 400 is assembled on the box frame 300, the pressing piece 120 does not push the locking rod 220 to move, and the locking rod 220 remains in the first position under the action of the first elastic piece 230. At this time, the locking rod 220 keeps the plug-in portion 211 engaged with the locking seat 210, thereby ensuring that the display module 400 is firmly assembled on the box frame 300; when it is necessary to remove the display module 400 from the box frame 300, the staff presses the pressing piece 120, and the pressing piece 120 pushes the locking rod 220 to shrink in the direction of the guide channel 212, and the locking rod 220 slides from the first position to the second position. At this time, the locking rod 220 releases the holding force of the plug-in portion 211 engaged with the connecting seat 110, and the plug-in portion 211 can be easily pulled out from the connecting channel 111, so that the display module 400 can be easily removed from the box frame 300, thereby facilitating the maintenance of the display module.

[0050] It should be noted that when the pressing member 120 is in the pressing process, the finger end 1222 of the elastic finger 122 abuts against the first locking member 250. As the pressing member 120 continuously approaches the plug-in portion 211, the elastic finger 122 gradually opens outward until it slides to the outermost portion of the first locking member 250. At the same time, when the locking rod 220 slides to the second position, the first clearance groove 221 coincides with the first guide hole 213, and the elastic finger 122 abuts against the exposed portion of the first locking member 250 (refer to Fig.11 and Fig.12 ), therefore, the side of the first locking member 250 is embedded in the first easing groove 221 under the action of the elastic finger 122, so that the locking rod 220 is engaged with the plug-in portion 211, and then the locking rod 220 is kept at the second position relative to the plug-in portion 211. Accordingly, the locking rod 220 releases the holding force of the plug-in portion 211 and the connecting seat 110. When the display module 400 is removed from the box frame 300, the locking rod 220 is effectively prevented from returning 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 the plug-in portion 211 and the connecting seat 110, and the display module 400 is more convenient to remove.

[0051] In some embodiments, reference Figure 4 , Figure 7 and Figure 8The fixing assembly 100 also includes a mounting base 130, a pressing base 140 and a second elastic member 150. The mounting base 130 is assembled and connected or integrated with the box frame 300. The connecting base 110 is integrated or assembled with one side of the mounting base 130. When the connecting base 110 is assembled and connected with the mounting base 130, the two can be fixedly assembled and connected or rotatably assembled and connected, which is specifically set according to actual needs. The pressing base 140 is assembled and connected to the other side of the mounting base 130. When the connecting base 110 is rotatably connected to the mounting base 130, the pressing base 140 can be used to keep the end of the connecting base 110 installed on the mounting base 130. A pressing channel 141 is provided on the inner side of the pressing base 140, and one end of the pressing channel 141 is connected to the pressing port 1111 of the connecting channel 111. The pressing member 120 is slidably disposed in the connection channel 111 of the pressing seat 140 and is snap-connected with the pressing seat 140. The pressing portion of the pressing member 120 is exposed at one end of the pressing seat 140 away from the connection seat 110, so that the staff can press the pressing member 120. The second elastic member 150 can be a spring. The second elastic member 150 is disposed 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. Therefore, the second elastic member 150 is used to provide an outward restoring force to the pressing member 120, so that the pressing member 120 is located at or reset to the position to be pressed. When the pressing member 120 is in the waiting position for pressing, the pressing protrusion 121 of the pressing member 120 and the extending end 224 of the locking rod 220 are in a separated state, and the elastic finger 122 and the first locking member 250 are in a separated state.

[0052] Specifically, before the display module 400 is assembled to the box frame 300, the pressing piece 120 is located in the pressing position under the action of the second elastic piece 150. At this time, when the plug-in part 211 is inserted into the connecting channel 111, the pressing protrusion 121 of the pressing piece 120 will not interfere with the movement of the locking rod 220, and the finger end 1222 of the elastic finger 122 will not interfere with the movement of the first locking piece 250, thereby ensuring that the plug-in part 211 can be smoothly inserted into the connecting channel 111, thereby facilitating the installation of the display module 400. When the display module 400 is detached from the box frame 300, the plug-in portion 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 not restricted by the first locking member 250, and the pressing member 120 is restored to the pressing position under the action of the second elastic member 150 to prepare for the next push of the locking rod 220. It can be seen that the setting of the second elastic member 150 facilitates the use of the pressing member 120.

[0053] Further, when the finger end 1222 of the elastic finger 122 contacts the first locking member 250, the pressing member 120 contacts the end of the locking rod 220. Specifically, during the disassembly process of the display module 400, when in the locked state, refer to Figure 4 and Fig. 9 , the pressing member 120 is in the waiting position for pressing, the inner side of the pressing member 120 is provided with a protruding pressing protrusion 121, the pressing protrusion 121 and the end of the locking rod 220 are separated, the elastic finger 122 and the first locking member 250 are separated, the locking rod 220 is in the first position, the first locking member 250 and the side wall of the locking rod 220 are in contact, and a large part of the first locking member 250 is exposed on the surface of the plug-in portion 211. In the first pressing stage, refer to Figure 4 and Fig.10 , the pressing member 120 is pressed to move toward the plug-in portion 211, and when the finger end 1222 of the elastic finger 122 contacts the side of the first locking member 250, the pressing protrusion 121 also contacts the end of the locking rod 220. In the second pressing stage, refer to Figure 4 and Fig.11 , the pressing member 120 is pressed to continue to move toward the plug-in portion 211, the pressing protrusion 121 pushes the locking rod 220 to slide toward the guide channel 212, the elastic finger 122 elastically deforms outwards and slides to the outermost portion of the first locking member 250 to provide the first locking member 250 with a force toward the first guide hole 213; 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 Fig.12 , the pressing member 120 is pressed to continue to move toward the plug-in portion 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, and the pressing protrusion 121 continues to push the locking rod 220 to slide toward 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, and the first locking member 250 is embedded inwardly into the first clearance groove 221 under the action of the elastic finger 122, so that the locking rod 220 remains in the second position to facilitate the disassembly of the display module 400.

[0054] It can be understood that in the second pressing stage, during the elastic deformation of the elastic finger 122, the pressing protrusion 121 of the pressing piece 120 also gradually pushes the locking rod 220 to slide toward the guide channel 212. With this arrangement, in the third pressing stage, the pressing piece 120 only needs to push the locking rod 220 to slide a short distance, and the first clearance groove 221 and the first guide hole 213 can overlap, thereby achieving the locking rod 220 and the plug-in part 211 being held together to facilitate the disassembly of the display module 400.

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

[0056] In some embodiments, reference Figure 4 and Figure 6 , the finger end 1222 of the elastic finger 122 is provided with a guide slope 1223 for sliding relative to the first locking member 250. Specifically, in the above-mentioned first pressing stage, when the finger end 1222 of the elastic finger 122 abuts against the first locking member 250, the guide slope 1223 abuts against the first locking member 250 accordingly. In the above-mentioned second pressing stage, the pressing member 120 is pressed to continue to move toward the direction of the plug-in portion 211, and the first locking member 250 slides relative to the guide slope 1223, thereby pushing the elastic finger 122 to elastically deform outward, thereby 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 side of the first locking member 250, so as to provide the first locking member 250 with an elastic holding force toward the first guide hole 213. It can be understood that, through the setting of the guide bevel 1223, when the pressing member 120 is pressed, the first locking member 250 can smoothly open the elastic finger 122 through the guide bevel 1223 to slide into the inner side of the elastic finger 122. As a result, the pressing member 120 can be smoothly pressed into the pressing channel 141 to push the locking 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, reference Figure 4 and Figure 6, a retaining groove 1221 is provided on the inner side of the elastic finger 122 along its length direction, and the retaining groove 1221 does not extend to the finger end 1222 of the elastic finger 122. The retaining groove 1221 is used for the first locking member 250 to be embedded, and the first locking member 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 member 250, the exposed part of the first locking member 250 is embedded in the retaining groove 1221. In the third pressing stage, when the pressing member 120 continues to move toward the plug-in portion 211, the first locking member 250 slides relative to the elastic finger 122 along the retaining groove 1221, so that the first guide hole 213 coincides with the first clearance groove 221, and then the first locking member 250 is embedded in the first clearance groove 221.

[0058] It is understandable that the elastic finger 122 can be arranged in the holding groove 1221 so that the first locking member 250 can be kept embedded in the holding groove 1221 to prevent the elastic finger 122 from being separated from the first locking member 250 under the action of the second elastic member 150. As a result, the inner side of the elastic finger 122 and the first locking member 250 can be kept in contact with each other, and the elastic finger 122 keeps the first locking member 250 embedded in the first yielding groove 221, so that the locking rod 220 is kept in the second position. In other words, under the restriction of the first locking member 250, the locking rod 220 will not be reset to the first position under the action of the first elastic member 230, so that the holding force of the plug-in portion 211 and the connecting seat 110 is always released, and the display module 400 can be easily removed from the box frame 300.

[0059] In some embodiments, reference Figure 4 and Figure 6, the first locking member 250 and the elastic fingers 122 are both provided with a plurality of them, and are provided in equal numbers, wherein the first locking members 250 are sequentially provided on the peripheral side of the plug-in portion 211, and are provided one-to-one with the elastic fingers 122. Specifically, the plug-in portion 211 is provided with a plurality of first guide holes 213 in sequence along its circumferential direction, and the first locking members 250 are movably provided one-to-one in the first guide holes 213. At the same time, the elastic fingers 122 are provided with a plurality of them, and the plurality of elastic fingers 122 are provided on the inner side of the pressing member 120, and are sequentially located around the pressing protrusion 121, and the elastic fingers 122 are provided one-to-one with the first locking member 250. It can be understood that when the locking 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 yielding groove 221. Therefore, multiple first locking members 250 cooperate to keep the locking rod 220 in the second position. The locking rod 220 always releases the retaining force of the plug-in portion 211 and the connecting seat 110, so that the plug-in portion 211 can be easily pulled out from the connecting channel 111, and then the display module 400 can be easily removed from the box frame 300.

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

[0061] It can be understood that the first elastic member 230 adopts the above-mentioned assembly method, and the lock seat 210, the first elastic member 230 and the locking rod 220 can be easily assembled together. In this way, the lock assembly 200 is assembled as a whole, so that the lock assembly 200 can be easily assembled to the bottom shell 410 of the display module 400; or, the lock seat 210, the first elastic member 230 and the locking rod 220 are assembled as a whole, and the staff can easily remove the lock 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 locking seat 210, one end of the first elastic member 230 is abutted against the bottom shell 410 of the display module 400, and the other end is abutted against the tail of the locking rod 220. Thus, the first elastic member 230 can provide an elastic force toward the connecting seat 110 to the locking rod 220, so that the locking rod 220 can be reset from the second position to the first position.

[0063] In some embodiments, reference Figure 2 , Figure 4 and Figure 5 The side of the plug-in portion 211 is provided with a second guide hole 214 connected to the guide channel 212. The lock assembly 200 also includes a second locking member 260. The second locking member 260 can be a ball but is not limited to a ball. For example, the second locking member 260 can also be a rod-shaped body with rounded corners at both ends. 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 clearance groove 222. When the lock rod 220 is in the first position, the second guide hole 214 is staggered with the second clearance groove 222 (refer to Fig. 9 ), the outer wall of the locking rod 220 abuts against the second locking member 260, so that the second locking member 260 has a locking portion exposed from the plug-in portion 211, and the locking portion is used to engage with the connecting seat 110; when the locking rod 220 is in the second position, the second guide hole 214 coincides with the second clearance groove 222 (refer to Fig.12 ), the second locking member 260 can move toward the second clearance groove 222 to be hidden in the side of the plug-in portion 211.

[0064] In a specific application, the lock seat 210 is connected to the bottom shell 410 of the display module 400, and the lock rod 220 is located at the first position under the action of the first elastic member 230, and the second clearance groove 222 on the lock rod 220 is staggered with the second guide hole 214 (refer to Fig. 9 ), the outer wall of the locking rod 220 abuts against the side of the second locking member 260 close to the guide channel 212. Therefore, under the restriction of the locking rod 220, the second locking member 260 is partially exposed outside the plug-in portion 211, thereby firmly engaging with the inner side of the connecting channel 111, thereby firmly assembling the display module 400 on the box frame 300. If it is necessary to remove the display module 400 from the box frame 300, the pressing member 120 pushes the locking rod 220 to slide into the guide channel 212 and slide to the second position. The second clearance groove 222 on the side wall of the locking rod 220 coincides with the second guide hole 214, and the second locking member 260 can move toward the second clearance groove 222 (refer to Fig.11), whereby the locking rod 220 releases the restriction on the second locking member 260, and the second locking member 260 can move toward the second give way groove 222, and the second locking member 260 is hidden in the side of the plug-in portion 211, thereby releasing the axial restriction between the locking seat 210 and the fixing seat, and the locking seat 210 and the fixing seat can be separated, so that the display module 400 can be easily removed from the box frame 300.

[0065] Instead of the above-mentioned locking 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 elastic arm can be elastically deformed outward or inward, and the locking part is a protrusion provided on the outside of the elastic arm. The locking rod 220 is movably provided between the elastic arms, and during the axial sliding process of the locking rod 220 between the elastic arms, the locking rod 220 controls the elastic arms to expand or contract, thereby controlling the locking part to protrude outward or contract inward, so that the axial restriction between the plug-in part 211 and the locking seat 210 can be released.

[0066] In some embodiments, reference Figure 7 and Figure 8 The fixing assembly 100 further includes an elastic energy storage member 160. The connecting seat 110 is rotatably disposed on the mounting base 130. The elastic energy storage member 160 is connected to the mounting base 130 and the connecting seat 110, and is used to store force when the connecting seat 110 rotates circumferentially. The plug-in portion 211 is provided with a retractable locking portion, which can be understood as the exposed portion of the second locking member 260. The inner peripheral wall of the connecting channel 111 is provided with a guide groove 1113 and a locking groove 1114 extending circumferentially and facing opposite directions (refer to Fig.13 ), one end of the guide groove 1113 is connected to the insertion port 1112, and the other end extends toward the extension port and is connected to the locking groove 1114. When the locking portion slides along the guide groove 1113, the connection seat 110 is adapted to rotate along a circumferential direction of the movement of the locking portion, so that the elastic energy storage member 160 stores energy; when the locking portion moves to the locking groove 1114, the elastic energy storage member 160 drives the connection seat 110 to rotate along another circumferential direction, so that the locking portion slides into the locking groove 1114.

[0067] Among them, the guide groove 1113 is spirally arranged on the inner 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 inclined on the inner wall of the connecting channel 111; and the locking groove 1114 is spirally arranged on the inner 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 assembly process of the display module 400 and the box frame 300, the locking part is aligned with the guide groove 1113 at the end of the plug-in port 1112, the plug-in portion 211 extends from the plug-in port 1112 into the connection channel 111, and the locking part slides into the locking groove 1114 along the guide groove 1113 and is retained in the locking groove 1114, thereby assembling and connecting the locking seat 210 to the fixing assembly 100, thereby conveniently assembling the display module 400 to the box frame 300. In the process of inserting the plug-in portion 211 into the connection channel 111, since the guide groove 1113 is extended from the plug-in port 1112 toward the other end of the connection channel 111, the guide groove 1113 is also circumferentially extended, so the locking part drives the connection seat 110 to rotate in the positive direction during the sliding process along the guide groove 1113, and the connection seat 110 pulls the elastic energy storage member 160 to be stretched in the positive 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 begins to release force to provide a circumferential force in the reverse direction to the connecting seat 110. As a result, the connecting seat 110 rotates in the reverse direction under the drive of the elastic energy storage member 160, so that the locking portion slides into the locking groove 1114, thereby realizing the fixed assembly connection of the locking seat 210 on the mounting base 130. Accordingly, the display module 400 is assembled on the box frame 300.

[0069] It should be emphasized that the locking groove 1114 needs to lock the locking part. When the locking groove 1114 extends circumferentially, the locking groove 1114 has a small axial extension or does not extend axially, so that the locking groove 1114 can lock the locking part. The present application effectively realizes that the locking part can slide into the locking groove 1114 through the provision of the elastic energy storage member 160; and after the elastic energy storage member 160 releases the force, the elastic energy storage member 160 maintains the position of the connecting seat 110 to limit the rotation of the connecting seat 110, so that the locking part remains in the locking groove 1114, thereby, the locking seat 210 is stably assembled on the fixing assembly 100.

[0070] In other possible embodiments, a limiting protrusion ring (not shown in the figure) is provided on the inner side of the connecting channel 111 near the plug-in port 1112. The limiting protrusion ring can also connect the locking seat 210 with the connecting seat 110 by restricting the locking portion, thereby assembling the display module 400 on the box frame 300.

[0071] In order to facilitate the installation of the elastic energy storage member 160, in some embodiments, refer to Figure 7 and Figure 8The mounting base 130 is provided with a panel portion 131 and an end cover portion 132, and the panel portion 131 is connected to the periphery of the end cover portion 132. The connection seat 110 is rotatably arranged in the center of the end cover portion 132, and a circular enclosure space is formed between the outer circumference of the connection seat 110 and the inner circumference of the panel portion 131; at the same time, the bottom of the connection seat 110 is provided with a flange portion 112 that expands to the periphery, and the flange portion 112 is arranged corresponding to the end cover portion 132. Among them, the inner side of the end cover portion 132 is provided with a first latch 1321 extending toward the flange portion 112, and the inner side of the flange portion 112 is provided with a second latch 113 extending toward the end cover portion 132, and the first latch 1321 and the second latch 113 are arranged at intervals in the circumferential direction of the enclosure space. The elastic energy storage member 160 can be a tension spring. The elastic energy storage member 160 is arranged in an arc shape in the enclosed 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 peripheral side between the mounting base 130 and the connecting base 110, so that it can effectively store force when the connecting base 110 rotates.

[0072] The present application also discloses a display device, referring to Figure 4 and Fig.14 , including a box frame 300, a display module 400 and the above-mentioned connecting lock: wherein the connecting seat 110 is connected to the box frame 300, and the locking seat 210 is assembled and connected or integrated with the bottom shell 410 of the display module 400.

[0073] In a specific application process, when the display module 400 is assembled on the box frame 300, the pressing piece 120 does not push the locking rod 220 to move, and the locking rod 220 remains in the first position under the action of the first elastic piece 230. At this time, the locking rod 220 keeps the plug-in portion 211 engaged with the locking seat 210, thereby ensuring that the display module 400 is firmly assembled on the box frame 300; when it is necessary to remove the display module 400 from the box frame 300, the staff presses the pressing piece 120, and the pressing piece 120 pushes the locking rod 220 to shrink in the direction of the guide channel 212, and the locking rod 220 slides from the first position to the second position. At this time, the locking rod 220 releases the holding force of the plug-in portion 211 and the connecting seat 110, and the plug-in portion 211 can be easily pulled out from the connecting channel 111, so that the display module 400 can be easily removed from the box frame 300.

[0074] It should be noted that when the pressing member 120 is in the pressing process, the finger end 1222 of the elastic finger 122 abuts against the first locking member 250. As the pressing member 120 continuously approaches the plug-in portion 211, the elastic finger 122 gradually opens outward until it slides to the outermost portion of the first locking member 250. At the same time, when the locking rod 220 slides to the second position, the first clearance groove 221 coincides with the first guide hole 213, and the elastic finger 122 abuts against the exposed portion of the first locking member 250 (refer to Fig.11 and Fig.12 ), therefore, the side of the first locking member 250 is embedded in the first easing groove 221 under the action of the elastic finger 122, so that the locking rod 220 is engaged with the plug-in portion 211, and then the locking rod 220 is kept at the second position relative to the plug-in portion 211. Accordingly, the locking rod 220 releases the holding force of the plug-in portion 211 and the connecting seat 110. When the display module 400 is removed from the box frame 300, the locking rod 220 is effectively prevented from returning 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 the plug-in portion 211 and the connecting seat 110, and the display module 400 is more convenient to remove.

[0075] 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.
