[0048] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0049] See also Figures 1 to 3 , a locking assembly 200 provided in an embodiment of the present invention, please refer to FIG. 1 to FIG. , a locking assembly 200 provided in an embodiment of the present invention, the locking assembly 200 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 locking assembly 200 includes a fixing assembly 100 and a locking assembly 200. The fixing assembly 100 is connected to a box frame 300 of the display device. The locking assembly 200 is connected to a bottom shell 410 of a display module 400 of the display device. The locking assembly 200 is connected to the fixing assembly 100, so that the display module 400 is assembled on the box frame 300.

[0050] Specifically, the fixing assembly 100 includes a mounting base 130, a connecting base 110 and a pressing member 120. The connecting base 110 is connected to the mounting base 130, and the two can be connected in an integrated manner or assembled. The connecting base 110 is provided with a connecting channel 111, and the connecting channel 111 forms an insertion port 1112 and a clearance port 1111 at both ends of the connecting base 110, respectively. The pressing member 120 can be pressed and set on the mounting base 130, and is set corresponding to the clearance port 1111. The locking assembly 200 includes a locking base 210, a locking rod 220 and a first elastic member 230. The lock seat 210 is provided with an inserting portion 211, the inserting portion 211 extends into the connecting channel 111 through the inserting port 1112, the inserting end 2111 of the inserting portion 211 is inserted into the inner side of the pressing member 120, and the inserting portion 211 is provided with a guide channel 212 that passes through the inserting end 2111 of the inserting portion 211. The lock rod 220 is slidably disposed in the guide channel 212, and the first elastic member 230 is used to act on the lock rod 220 in the inserting direction of the inserting portion 211, so that the lock rod 220 is located at the first position or slides from the first position to the second position.

[0051] Among them, the pressing piece 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 locking rod 220 provides a retaining force for the plug-in portion 211 to be clamped with the connecting seat 110; when the locking rod 220 is in the second position, the pressing piece 120 is clamped with the mounting base 130 and releases the retaining force for the plug-in portion 211 to be clamped with the connecting seat 110.

[0052] 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 provides a holding force for the plug-in portion 211 to be connected to the connecting seat 110, 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 for the plug-in portion 211 to be connected to 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 400.

[0053] It should be noted that when the locking rod 220 slides to the second position, the pressing piece 120 is engaged with the mounting base 130, so that the locking rod 220 is maintained in the second position. Therefore, when the display module 400 is removed 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 provide a retaining force to the plug-in portion 211 to engage with the connecting seat 110, thereby ensuring the convenience of disassembly of the display module 400.

[0054] In some embodiments, reference Figures 3 to 5 The fixing assembly 100 further includes a pressing seat 140, which facilitates the installation of the pressing member 120. Specifically, the end of the connecting seat 110 close to the clearance opening 1111 is connected to one side of the mounting base 130, and the edge of the mounting base 130 is provided with a lug, which is fixedly assembled on the box frame 300 by screws, so as to facilitate the mounting base 130 to be assembled on the box frame 300. At the same time, the pressing seat 140 is assembled and connected to the side of the mounting base 130 away from the connecting seat 110, or the two are connected in an integrated manner. The mounting base 130 is provided with a pressing channel 141 running through both ends thereof, and one end of the pressing channel 141 is arranged corresponding to the clearance opening 1111.

[0055] The pressing member 120 is slidably disposed in the pressing channel 141 , and at least one of the inner side of the pressing seat 140 and the inner side of the pressing member 120 is provided with an elastic clamping claw 122 , which can be elastically deformed to be snap-connected with the other one. For example, the elastic claw 122 is arranged on the pressing piece 120, and the elastic claw 122 is elastically deformed during the sliding of the pressing piece 120 to be snap-connected with the pressing seat 140 to keep the locking rod 220 in the second position; or, the elastic claw 122 is arranged on the inner side of the pressing seat 140, and the elastic claw 122 is elastically deformed during the sliding of the pressing piece 120 to be snap-connected with the pressing piece 120 to keep the locking rod 220 in the second position; or, the elastic claw 122 is provided on the pressing seat 140 and the elastic claw 122 is also provided on the inner side of the pressing piece 120, and the elastic claw 122 on the pressing seat 140 is snap-connected with the elastic claw 122 on the pressing piece 120 to keep the locking rod 220 in the second position.

[0056] In the specific application process, when the display module 400 needs to be disassembled, the staff presses the pressing member 120 to move in the direction of the plug-in portion 211. The inner side of the pressing member 120 is provided with a pressing column 121, which abuts against the protruding end 223 of the locking rod 220, and pushes the locking rod 220 to slide from the first position to the second position with the movement of the pressing member 120. The locking rod 220 releases the holding force of the plug-in portion 211 and the connecting seat 110, thereby facilitating the disassembly of the display module 400 from the box frame 300. In the process of the pressing member 120 sliding along the pressing channel 141, the elastic clamping claw 122 gradually deforms elastically. When the locking rod 220 slides to the second position, the elastic clamping claw 122 just realizes the buckle connection. At this time, the locking rod 220 can be used to keep the elastic clamping claw 122 in the buckle connection. Therefore, the elastic clamping claw 122 keeps the locking rod 220 in the second position, thereby facilitating the disassembly of the display module 400.

[0057] In some embodiments, reference Figure 3 and Figure 4 The fixing assembly 100 also includes a second elastic member 150, which can be a spring. The second elastic member 150 is arranged in the pressing channel 141, and one end of the second elastic member 150 is abutted against one end of the pressing seat 140 close to the mounting base 130, and the other end is abutted against the pressing member 120. Therefore, the second elastic member 150 is used to provide an elastic force in the opposite direction of the pressing to the pressing member 120, so that the pressing member 120 can be reset to the position to be pressed, in preparation for pushing the locking rod 220 next time.

[0058] Furthermore, when the locking rod 220 is in the second position, the locking rod 220 acts on the elastic clamping claw 122 so that the elastic clamping claw 122 maintains the snap connection. Specifically, when the pressing member 120 pushes the locking rod 220 to slide from the first position to the second position, the locking rod 220 just acts on the elastic clamping claw 122, and the elastic elastic clamping claw 122 maintains this posture, thereby achieving the above-mentioned snap connection, and then keeping the pressing member 120 in the pressed position. Because the pressing member 120 overcomes the elastic force of the first elastic member 230 and resists the locking rod 220, the locking rod 220 is maintained in the second position under the action of the pressing member 120, and the locking rod 220 releases the retention force of the plug-in portion 211 and the connecting seat 110, thereby facilitating the disassembly of the display module 400. When the plug-in portion 211 and the locking rod 220 are separated from the connecting seat 110, the locking rod 220 releases the holding force on the elastic clamp 122, and the elastic clamp 122 returns to its initial state. The elastic clamp 122 releases its snap connection, thereby releasing the snap connection between the pressing member 120 and the pressing seat 140. The pressing member 120 returns to the waiting position under the action of the second elastic member 150 to prepare for the next push of the locking rod 220.

[0059] In some specific embodiments, referring to Figure 3 , Figure 5 and Figure 6 The inner side of the pressing seat 140 is provided with a plurality of locking claws 143 along its circumferential direction. The locking claws 143 can be extended toward the clearance opening 1111 or toward the pressing member 120. The locking claws 143 are located around the locking rod 220, and each locking claw 143 is provided with a first locking portion 1431. Meanwhile, the inner side of the pressing member 120 is provided with a pressing column 121 extending toward the clearance opening 1111. The pressing column 121 is used to contact with the protruding end 223 of the locking rod 220 to push the locking rod 220 to slide from the first position to the second position. The elastic claws 122 are provided on the inner side of the pressing member 120 and are located around the pressing column 121. Each elastic claw 122 is provided with a second locking portion 1221. When the locking rod 220 is in the second position, the first locking portion 1431 and the second locking portion 1221 are snap-connected along the axial direction of the pressing channel 141 to limit the pressing member 120 from resetting to the pressing position under the action of the second elastic member 150, thereby keeping the locking rod 220 in the second position.

[0060] Among them, when the lock rod 220 is in the second position, the lock claw 143 can be understood as an elastic claw, and the lock rod 220 is located on the inner side of the lock claw 143. The lock rod 220 can keep the lock claw 143 in an open state, so that the first lock part 1431 is snap-connected with the second lock part 1221 (not shown in the figure). Alternatively, the lock rod 220 is located on the inner side of the elastic claw 122, and the lock rod 220 can keep the elastic claw 122 in an open state, so that the first lock part 1431 is snap-connected with the second lock part 1221.

[0061] Specifically, when the pressing seat 140 pushes the locking rod 220 to slide toward the guide channel 212, the second locking portion 1221 slides along the outer side of the locking claw 143 and gradually deforms elastically outward. When the second locking portion 1221 passes over the position of the first locking portion 1431, the second locking portion 1221 is elastically reset to be snap-connected with the first locking portion 1431. At this time, the locking rod 220 acts on the locking claw 143 or the elastic claw 122 to keep the first locking portion 1431 snap-connected with the second locking portion 1221. When the plug-in portion 211 is separated from the connecting seat 110, the locking rod 220 releases the restriction on the locking claw 143 or the elastic claw 122, and the first locking portion 1431 is separated from the second locking portion 1221. At this time, the pressing member 120 is restored to the waiting position under the action of the second elastic member 150 to prepare for the next push of the locking rod 220.

[0062] In further specific embodiments, reference is also made to Figure 7The pressing seat 140 is provided with an annular boss 142 located at the pressing channel 141 at the end near the mounting base 130, and one end of the first elastic member 230 is held against the annular boss 142 to be held on the pressing seat 140. The inner edge of the annular boss 142 is provided with locking jaws 143 in sequence along its circumferential direction. The locking jaws 143 extend toward the pressing member 120 and gradually shrink. The locking jaws 143 are located around the plug-in portion 211 and the locking rod 220; wherein the first locking portion 1431 is a circumferential protrusion provided on the locking jaw 143, and the second locking portion 1221 is a circumferential protrusion provided on the elastic jaw 122. Among them, along the circumferential direction of the pressing channel 141, a clearance gap is reserved between adjacent locking jaws 143, the clearance gap is used to make room for the extension arm of the elastic jaw 122, and the first locking portion 1431 overlaps with the second locking portion 1221 in the circumferential direction.

[0063] When the pressing member 120 slides toward the plug-in portion 211, the elastic clamping claw 122 slides in the clearance gap, and the second locking portion 1221 passes over the first locking portion 1431 along the outer side of the first locking portion 1431 to be snap-connected with the second locking portion 1221. The locking rod 220 is located between the elastic clamping claws 122 to limit the elastic clamping claws 122 from contracting with each other.

[0064] Specifically, during the pressing process of the pressing member 120, the claw end of the elastic claw 122 abuts against the end of the locking claw 143, and as the pressing member 120 continues to push, the extension arm of the elastic claw 122 slides in the clearance gap, and the second locking portion 1221 gradually moves along the outer side of the first locking portion 1431 toward the clearance opening 1111, and the second locking portion 1221 elastically deforms outward under the action of the second locking portion 1221. When the second locking portion 1221 passes over the first locking portion 1431, the elastic deformation of the second locking portion 1221 begins to reset, thereby being snap-connected with the first locking portion 1431; at the same time, the pressing column 121 just pushes the locking rod 220 to the second position (refer to Figures 10 to 12 ).

[0065] It is understandable that, referring to Figures 6 to 9When the lock bar 220 is in the second position, the inner side of the elastic clamping claw 122 is provided with a convex rib 1223 along its length direction, and the convex rib 1223 abuts against the side of the lock bar 220, so that the elastic clamping claw 122 is in an unfolded state under the restriction of the lock bar 220 to ensure that the first locking portion 1431 and the second locking portion 1221 are in a snap-connected state. Therefore, the pressing member 120 remains in a pressed state, and the pressing member 120 overcomes the force of the first elastic member 230 to keep the lock bar 220 in the second position, thereby facilitating the disassembly of the display module 400. When the display module 400 needs to be disassembled, the locking rod 220 is separated from the connecting seat 110 along with the plug-in portion 211. The elastic clamp 122 shrinks toward the space between the locking clamps 143 without the restriction of the locking rod 220. Correspondingly, the second locking portion 1221 also moves toward the space between the locking clamps 143 to separate from the first locking portion 1431. At this time, the locking clamp 143 releases the axial restriction of the elastic clamp 122. Under the action of the second elastic member 150, the locking clamp 143 slides away from the yield outlet 1432 between the ends of the locking clamp 143. Therefore, the pressing member 120 is restored to the waiting position under the action of the second elastic member 150 to prepare for the next push of the locking rod 220.

[0066] It should be noted that when the elastic jaw 122 slides away from the locking jaw 143 from the clearance outlet 1432, the locking jaw 143 can be elastically deformed outwards, so that the elastic jaw 122 can smoothly slide away from the locking jaw 143. Of course, the size of the clearance outlet 1111 is set large enough, and when the elastic jaw 122 slides away from the clearance outlet 1432, the locking jaw 143 does not need to be deformed.

[0067] In some embodiments, reference Figure 8 and Fig. 9 , the extension length of the elastic clamping claw 122 toward the clearance opening 1111 is greater than the extension length of the pressing column 121 toward the clearance opening 1111; and / or, the extended end 223 of the locking rod 220 is retracted in the space between the locking clamping claws 143, so that when the second locking portion 1221 slides to the outside of the first locking portion 1431, the pressing column 121 does not abut against the locking rod 220 (refer to Fig.10 and Fig.11 ).

[0068] It is understandable that when the pressing member 120 is pressed and moves toward the plug-in portion 211, the elastic clamping claw 122 abuts against the locking clamping claw 143 and deforms outward, and the pressing end of the pressing seat 140 and the extended end 223 of the locking rod 220 still maintain a small distance (refer to Fig.11), when the second locking portion 1221 moves forward along the outer wall of the first locking portion 1431, the pressing end of the pressing seat 140 abuts against the protruding end 223 of the locking rod 220 and pushes the locking rod 220 to slide from the first position to the second position (refer to Fig.12 It should be noted that, when the first locking portion 1431 moves relative to the second locking portion 1221, the pressing column 121 pushes the locking rod 220 to shrink in the direction of the guide channel 212. Therefore, when the second locking portion 1221 passes over the first locking portion 1431, the pressing column 121 will not excessively push the locking rod 220 in the direction of the guide channel 212, thereby ensuring that the rib 1223 on the inner side of the elastic clamping claw 122 can be supported on the side of the locking rod 220, thereby ensuring that the elastic clamping claw 122 is in an expanded state. In this way, the second locking portion 1221 is kept in a snap connection with the first locking portion 1431 to overcome the first elastic member 130 and keep the locking rod 220 in the second position.

[0069] In some embodiments, reference Figures 6 to 9 , the claw end of each locking claw 143 is provided with an extended first positioning convex strip 144, and the pressing column 121 is arranged between each first positioning convex strip 144. For example, four elastic claws 122 are provided, and the four elastic claws 122 are provided with first positioning convex strips 144 extending toward the pressing member 120. Four second positioning convex strips 1211 are arranged around the pressing column 121, and the pressing column 121 is located between the four first positioning convex strips 144. The second positioning convex strips 1211 around the pressing column 121 are arranged one by one with the first positioning convex strips 144, so that the pressing column 121 positions the four elastic claws 122 respectively to prevent the four elastic claws 122 from elastically deforming inward. In this way, when the second locking portion 1221 slides along the outer side of the first locking portion 1431 toward the yield opening 1111, the second positioning ridges 1211 around the pressing column 121 effectively limit the inward deformation of the elastic clamping claw 122 through the first positioning ridges 144, thereby ensuring that the second locking portion 1221 can smoothly pass over the first locking portion 1431 along the outer side of the first locking portion 1431, thereby ensuring the smoothness of the pressing member 120 when being pressed.

[0070] In order to facilitate the assembly of the first elastic member 230, in some specific embodiments, refer to Figure 3 and Figure 5The 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 222, and a fixing ring 240 is sleeved and fixed on the annular groove 222, 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.

[0071] 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.

[0072] 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.

[0073] In some embodiments, reference Figure 1 , Figure 2 and Figure 5 The side of the plug-in portion 211 is provided with a guide hole 213 connected to the guide channel 212. The lock assembly 200 also includes a locking member 250. The locking member 250 can be a ball but is not limited to a ball. For example, the locking member 250 can also be a rod-shaped body with rounded corners at both ends. The locking member 250 is movably arranged in the guide hole 213; wherein the side wall of the locking rod 220 is provided with a clearance groove 221. When the locking rod 220 is in the first position, The guide hole 213 is staggered with the clearance groove 221, and the outer peripheral wall of the locking rod 220 is abutted against the locking member 250, so that the locking member 250 has a locking portion exposed from the plug-in portion 211, and the locking portion is used to be snapped with the connecting seat 110; when the locking rod 220 is in the second position, the guide hole 213 and the clearance groove 221 coincide with each other (refer to the figure), and the locking member 250 can move toward the clearance groove 221 to be hidden in the side of the plug-in portion 211.

[0074] 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 clearance groove 221 on the lock rod 220 is staggered with the guide hole 213 (refer to Fig. 9 ), the outer wall of the locking rod 220 abuts against the side of the locking member 250 close to the guide channel 212. Therefore, under the restriction of the locking rod 220, the locking member 250 is partially exposed to the outside of 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 piece 120 pushes the locking rod 220 to slide into the guide channel 212 and slide to the second position. The clearance groove 221 on the side wall of the locking rod 220 coincides with the guide hole 213, and the locking piece 250 can move toward the clearance groove 221 (refer to the figure). As a result, the locking rod 220 releases the restriction on the locking piece 250, and the locking piece 250 can move toward the clearance groove 221. The locking piece 250 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. 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.

[0075] 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.

[0076] In some embodiments, reference Figures 2 to 4 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. Among them, the plug-in portion 211 is provided with a retractable locking portion, which can be understood as the exposed portion of the locking member 250. 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.

[0077] 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 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 degrees.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] In order to facilitate the installation of the elastic energy storage member 160, in some embodiments, refer to Figure 2 and Figure 4 The 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 connecting 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 connecting seat 110 and the inner circumference of the panel portion 131; at the same time, the bottom of the connecting 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 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 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 pin (not shown in the figure), and the other end is hooked on the second pin 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.

[0082] The present application also discloses a display device, which, with reference to Figures and Figures, includes 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.

[0083] 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 provides a holding force for the plug-in portion 211 to be connected to the connecting seat 110, 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 for the plug-in portion 211 to be connected to 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 400.

[0084] It should be noted that when the locking rod 220 slides to the second position, the pressing piece 120 is engaged with the mounting base 130, so that the locking rod 220 is maintained in the second position. Therefore, when the display module 400 is removed 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 provide a retaining force to the plug-in portion 211 to engage with the connecting seat 110, thereby ensuring the convenience of disassembly of the display module 400.

[0085] 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.
