[0007] Wherein, when the locking part slides along the guide groove, the rotating seat is suitable for the movement of the locking part to rotate in a circumferential direction so that the elastic energy storage member stores energy; when the locking part moves to the locking groove, the elastic energy storage member drives the rotating seat to rotate in another circumferential direction so that the locking part slides into the locking groove.

[0008] According to some embodiments of the present invention, the guide groove is spirally arranged on the inner circumferential wall of the fixed channel, and the spiral angle of the guide groove is less than or equal to 15 degrees; or, the guide groove is circumferentially inclined on the inner circumferential wall of the fixed channel.

[0009] According to some embodiments of the present invention, the locking groove is spirally arranged on the inner circumferential wall of the fixing channel, and the spiral angle of the guide groove is greater than or equal to 20 degrees.

[0010] According to some embodiments of the present invention, the plug-in portion is provided with a movable channel along its axial direction, and the locking assembly further includes a locking rod, which is slidably disposed in the movable channel or circumferentially rotated in the movable channel to control the locking portion to separate from the locking groove.

[0011] According to some embodiments of the present invention, the locking portion is a ball that is radially movably arranged on the side of the plug-in portion and abuts against the locking rod.

[0012] According to some embodiments of the present invention, the plug-in portion is provided with elastic arms in sequence in the circumferential direction of the movable channel, the locking portion is a protrusion arranged on the outside of the elastic arm, and the locking rod is movable to control the expansion or contraction of the elastic arm when rotating or sliding.

[0013] According to some embodiments of the present invention, the elastic arm is provided with a first extension section and a second extension section connected to each other, and the inner side of the second extension section is protruded inwardly relative to the inner side of the first extension section; wherein the locking rod is provided with an outer protrusion, and when the outer protrusion slides to the inner side of the second extension section, the locking portion can remain embedded in the locking groove; when the outer protrusion slides to the inner side of the first extension section, the locking portion can be separated from the locking groove.

[0014] According to some embodiments of the present invention, if the locking rod is axially slidably arranged in the movable channel, the locking assembly further includes an elastic member arranged on the locking seat, and the elastic member is used to provide an elastic force toward the rotating seat to the locking rod so that the locking rod can be reset to the locking position; wherein, when the locking rod is displaced to the locking position, the locking rod keeps the locking portion embedded in the locking groove.

[0015] According to some embodiments of the present invention, the plug-in end of the plug-in portion is provided with a first extension opening, the end of the rotating seat away from the plug-in port is provided with a second extension opening, the locking rod is passed through the first extension opening and the second extension opening, and extends to the outer bottom of the fixed seat; and / or,

[0016] The bottom of the lock seat away from the rotating seat is provided with a clearance opening connected to the movable channel; wherein the lock rod is made of a magnetic material, and the lock rod can be moved toward the clearance opening by the magnetic attraction force from the clearance opening; and / or the lock rod can be moved toward the clearance opening by the negative pressure from the clearance opening.

[0017] In a second aspect, an embodiment of the present application provides a display device, including:

[0018] Box frame and display module;

[0019] In the above-mentioned locking mechanism, the fixing seat is assembled and connected to the box frame or connected in an integrated manner, and the locking seat is assembled and connected to the bottom shell of the display module or connected in an integrated manner.

[0020] It can be seen from the above technical scheme that the embodiment of the present application has the following advantages: during the assembly process of the display module and the box frame, the locking part is aligned with the guide groove at the port of the plug interface, the plug-in part extends from the plug interface into the fixed channel, and the locking part slides into the locking groove along the guide groove and is retained in the locking groove, thereby assembling the locking seat to the fixed component, thereby conveniently assembling the display module on the box frame. In the process of inserting the plug-in part into the fixed channel, since the guide groove is extended from the plug interface toward the other end of the fixed channel, the guide groove is also extended circumferentially, so the locking part drives the rotating seat to rotate in the positive direction during the sliding process along the guide groove, and the rotating seat pulls the elastic energy storage member to be stretched in the positive direction, and the elastic energy storage member is effectively stored. When the locking part moves to the position of the locking groove, the elastic energy storage member starts to release force to provide a circumferential force in the reverse direction to the rotating seat. As a result, the rotating seat rotates in the reverse direction under the drive of the elastic energy storage member, so that the locking part can slide into the locking groove, thereby realizing the fixed assembly connection of the locking seat to the fixed seat. Accordingly, the display module is assembled on the box frame.

[0021] It should be emphasized that the locking groove needs to lock the locking part. When the locking groove extends in the circumferential direction, the axial extension of the locking groove is small or not extended axially, so that the locking groove can lock the locking part. The present application effectively realizes that the locking part can slide into the locking groove through the provision of the elastic energy storage member; and after the elastic energy storage member releases the force, the elastic energy storage member maintains the position of the rotating seat to limit the rotation of the rotating seat, so that the locking part remains in the locking groove, thereby, the locking seat is stably assembled on the fixed component.

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0037] See also Figures 1 to 3 , a locking mechanism provided by an embodiment of the present invention, which is applied to a display device, and is described by taking the application to the display device as an example, but is not limited to being used only for the display device. The locking mechanism includes a fixing component 100 and a locking component 200, the fixing component 100 is fixed to the box frame 400 of the display device, the locking component 200 is connected to the bottom shell 310 of the display module 300 of the display device, and the locking component 200 is connected to the fixing component 100, so that the display module 300 is assembled on the box frame 400 (refer to Figure 6 and Figure 7 ).

[0038] The fixing assembly 100 includes a fixing seat 110, a rotating seat 120 and an elastic energy storage member 130. The fixing seat 110 is integrated or assembled and connected to the box frame 400. The rotating seat 120 is rotatably arranged on the fixing seat 110. The elastic energy storage member 130 is connected to the fixing seat 110 and the rotating seat 120, and is used to store energy when the rotating seat 120 rotates circumferentially. The rotating seat 120 is provided with a connecting fixing channel 121 and an insertion port 122, and the inner peripheral wall of the movable channel 2111 is provided with a guide groove 124 and a locking groove 125 extending circumferentially and facing opposite directions (refer to Figure 5 ), one end of the guide groove 124 is connected to the plug interface 122, and the other end extends away from the plug interface 122 and is connected to the locking groove 125.

[0039] The locking assembly 200 includes a locking seat 210, which is integrated or assembled on the bottom shell 310 of the display module 300. A protruding locking portion 213 is provided on the side of the plug-in portion 211. The plug-in portion 211 extends into the fixing channel 121 through the plug-in port 122, and the locking portion 213 slides into the locking groove 125 along the guide groove 124; wherein, when the locking portion 213 slides along the guide groove 124, the rotating seat 120 is adapted to rotate along a circumferential direction for the movement of the locking portion 213, so that the elastic energy storage member 130 stores energy; when the locking portion 213 moves to the locking groove 125, the elastic energy storage member 130 drives the rotating seat 120 to rotate along another circumferential direction, so that the locking portion 213 slides into the locking groove 125.

[0040] Specifically, during the assembly process of the display module 300 and the box frame 400, the locking portion 213 is aligned with the guide groove 124 at the end of the plug-in port 122, the plug-in portion 211 extends from the plug-in port 122 into the fixed channel 121, and the locking portion 213 slides into the locking groove 125 along the guide groove 124 and is retained in the locking groove 125, thereby assembling and connecting the locking seat 210 to the fixed assembly 100, thereby conveniently assembling the display module 300 to the box frame 400. In the process of inserting the plug-in portion 211 into the fixed channel 121, since the guide groove 124 is extended from the plug-in port 122 toward the other end of the fixed channel 121, the guide groove 124 is also circumferentially extended, so the locking portion 213 drives the rotating seat 120 to rotate in the positive direction during the sliding process along the guide groove 124, and the rotating seat 120 pulls the elastic energy storage member 130 to be stretched in the positive direction, and the elastic energy storage member 130 is effectively stored. When the locking portion 213 moves to the position of the locking groove 125, the elastic energy storage member 130 begins to release force to provide a circumferential force in the reverse direction to the rotating seat 120. As a result, the rotating seat 120 rotates in the reverse direction under the drive of the elastic energy storage member 130, so that the locking portion 213 slides into the locking groove 125, thereby realizing the fixed assembly connection of the locking seat 210 to the fixed seat 110. Accordingly, the display module 300 is assembled on the box frame 400.

[0041] It should be emphasized that the locking groove 125 needs to lock the locking portion 213. When the locking groove 125 extends circumferentially, the locking groove 125 has a small axial extension or does not extend axially, so that the locking groove 125 can lock the locking portion 213. The present application effectively realizes that the locking portion 213 can slide into the locking groove 125 through the provision of the elastic energy storage member 130; and after the elastic energy storage member 130 releases the force, the elastic energy storage member 130 maintains the position of the rotating seat 120 to limit the rotation of the rotating seat 120, so that the locking portion 213 remains in the locking groove 125, thereby, the locking seat 210 is stably assembled on the fixing assembly 100.

[0042] In some embodiments, reference Figure 2 and Figure 3 The guide groove 124 is spirally arranged on the inner wall of the fixed channel 121 (for details, please refer to Figure 5 ), the spiral angle of the guide groove 124 is less than or equal to 15 degrees. With this arrangement, the spiral angle of the guide groove 124 is smaller than its self-locking angle. In other words, during the circumferential extension of the guide groove 124, the guide groove 124 extends a greater length in the axial direction of the fixed channel 121. With this arrangement, when the staff pushes the locking portion 213 to slide along the guide groove 124, the locking portion 213 can drive the rotating seat 120 to rotate, thereby allowing the elastic energy storage member 130 to effectively store force for subsequent driving of the rotating seat 120 to rotate.

[0043] In other possible embodiments, the guide groove 124 is circumferentially inclined on the inner circumferential wall of the fixed channel 121, and the guide groove 124 has an inclination angle of less than 50 degrees relative to the length direction of the movable channel 2111. In other words, during the circumferential extension of the guide groove 124, the guide groove 124 extends a greater length along the length direction of the fixed channel 121. With such a configuration, when the staff pushes the locking portion 213 to slide along the guide groove 124, the locking portion 213 can drive the rotating seat 120 to rotate, so that the elastic energy storage member 130 can effectively store force for driving the rotating seat 120 to rotate later.

[0044] In some embodiments, reference Figure 2 and Figure 3 The locking groove 125 is spirally arranged on the inner wall of the fixing channel 121 (for details, please refer to Figure 5 ), the spiral angle of the guide groove 124 is greater than or equal to 20 degrees. With this arrangement, the spiral angle of the guide groove 124 is less than or equal to its self-locking angle. In other words, during the circumferential extension of the guide groove 124, the extension length of the guide groove 124 along the length direction of the fixed channel 121 is relatively small. With this arrangement, after the locking portion 213 slides into the locking groove 125, the locking portion 213 can be retained in the locking groove 125 and will not slide into the guide groove 124, so that the locking seat 210 can be firmly assembled on the fixing component 100, thereby ensuring that the display module 300 is firmly assembled on the box frame 400.

[0045] It should be noted that the locking groove 125 is arranged in a spiral shape. When the elastic energy storage member 130 drives the rotating seat 120 to rotate, the rotating seat 120 pulls the locking seat 210 toward the fixed component 100 through the locking portion 213, thereby reducing the gap between the display module 300 and the box frame 400, thereby ensuring the flatness of the display module 300.

[0046] In other possible embodiments, the locking groove 125 only extends circumferentially and does not extend axially. The locking groove 125 can also lock the locking portion 213 to prevent the locking portion 213 from escaping from the locking groove 125 and sliding into the guide groove 124, thereby ensuring that the display module 300 is firmly assembled on the box frame 400.

[0047] In order to facilitate the installation of the elastic energy storage member 130, in some embodiments, refer to Figure 2 and Figure 3 The fixed seat 110 is provided with a panel portion 111 and an end cover portion 112, and the panel portion 111 is connected to the periphery of the end cover portion 112. The rotating seat 120 is rotatably arranged at the center of the end cover portion 112, and an annular enclosed space 113 is formed between the outer circumference of the rotating seat 120 and the inner circumference of the panel portion 111 (refer to Figure 4 ); At the same time, the bottom of the rotating seat 120 is provided with a flip cover portion 126 that expands in all directions, and the flip cover portion 126 is arranged corresponding to the end cover portion 112. Among them, the inner side of the end cover portion 112 is provided with a first latch 114 extending toward the flip cover portion 126, and the inner side of the flip cover portion 126 is provided with a second latch 127 extending toward the end cover portion 112. The first latch 114 and the second latch 127 are arranged at intervals in the circumferential direction of the enclosed space 113. The elastic energy storage member 130 can be a tension spring, which is arranged in an arc shape in the enclosed space 113, one end of the tension spring is hooked on the first latch 114, and the other end is hooked on the second latch 127. Therefore, the elastic energy storage member 130 is conveniently connected to the circumferential side between the fixed seat 110 and the rotating seat 120, so that it can effectively store force when the rotating seat 120 rotates.

[0048] In some embodiments, reference Figures 2 to 4 The locking assembly 200 also includes a locking rod 220. The plug-in portion 211 is provided with a movable channel 2111 along its axial direction. The locking rod 220 is slidably disposed in the movable channel 2111 along the axial direction of the plug-in portion 211 to control the locking portion 213 to separate from the locking groove 125; alternatively, the locking rod 220 is circumferentially rotated in the movable channel 2111 to control the locking portion 213 to separate from the locking groove 125.

[0049] In specific applications, when the display module 300 needs to be disassembled, the staff controls the locking rod 220 to slide axially or rotate circumferentially, thereby controlling the locking portion 213 to shrink in the radial direction, and the locking portion 213 is radially separated from the locking groove 125, thereby releasing the axial restriction between the plug-in portion 211 and the rotating seat 120. As a result, the plug-in portion 211 can be easily pulled out of the fixed channel 121, and then the display module 300 can be easily removed from the box frame 400.

[0050] In other possible embodiments, the locking portion 213 is a locking member (not shown) elastically contracted and arranged on the side of the plug-in portion 211, and the end of the locking member is rounded. When the display module 300 is disassembled, if the user acts on the display module 300 in a direction away from the box frame 400, the locking member contracts toward the inner side of the plug-in portion 211, thereby releasing the axial restriction between the plug-in portion 211 and the rotating seat 120, so that the display module 300 can be easily disassembled from the box frame 400.

[0051] In order to enable the locking rod 220 to control the contraction of the locking portion 213, in a possible embodiment, referring to Figures 2 to 4 The plug-in portion 211 is provided with elastic arms 212 in sequence in the circumferential direction of the active channel 2111. Each elastic arm 212 can be elastically deformed outward or inward. The locking portion 213 is a protrusion provided on the outside of the elastic arm 212. The locking rod 220 is movably provided between the elastic arms 212. When the plug-in portion 211 slides circumferentially or rotates circumferentially in the active channel 2111, the locking rod 220 controls the elastic arms 212 to expand or contract, thereby controlling the locking portion 213 to protrude outward or contract inward.

[0052] In the specific application process, when the display module 300 is assembled on the box frame 400, the staff can conveniently control each elastic arm 212 to be in the unfolded state through the locking rod 220, and the locking part 213 is in the state of protruding outward, and the locking part 213 can slide into the locking groove 125 along the guide groove 124, so that the locking seat 210 is connected with the fixing assembly 100, and then the display module 300 is firmly assembled on the box frame 400. When the display module 300 needs to be removed from the box frame 400, the staff can conveniently release the restriction on the elastic arm 212 through the locking rod 220, and the elastic arm 212 can be elastically deformed inwardly, so that the locking part 213 is in a contracted state, thereby, the locking part 213 radially disengages from the locking groove 125, thereby releasing the axial restriction between the plug-in part 211 and the rotating seat 120, and the plug-in part 211 can be conveniently withdrawn from the fixing channel 121, so that the display module 300 can be conveniently removed from the box frame 400.

[0053] In order to enable the locking rod 220 to control the elastic arm 212 to elastically contract, in a specific embodiment, the elastic arm 212 is provided with a first extension section 2121 and a second extension section 2122 connected along the length direction of the elastic arm 212 (see Figure 4), the first extension section 2121 is connected to the bottom of the locking seat 210, the second extension section 2122 is arranged relative to the first extension section 2121 and close to the fixing seat 110, and the locking portion 213 is arranged outside the second extension section 2122. The inner side of the second extension section 2122 is thickened relative to the inner side of the first extension section 2121, or in other words, the inner side of the second extension section 2122 is convex inwardly relative to the inner side of the first extension section 2121.

[0054] The locking rod 220 is provided with an outer protrusion 221. When the side wall of the outer protrusion 221 abuts against the inner side of the second extension section 2122, the elastic arm 212 is in an outwardly expanded state, and the locking portion 213 is in an outwardly protruding state, so that it is embedded in the locking groove 125 to axially limit the plug-in portion 211 and the rotating seat 120, thereby ensuring that the display module 300 is firmly assembled on the box frame 400. When the side wall of the outer protrusion 221 is located on the inner side of the first extension section 2121, the elastic arm 212 can be elastically deformed inwardly, so that the locking portion 213 can be in a contracted state, so that the locking portion 213 can radially disengage from the locking groove 125, thereby releasing the axial restriction between the plug-in portion 211 and the rotating seat 120, and the plug-in portion 211 can be conveniently withdrawn from the fixing channel 121, so that the display module 300 can be conveniently removed from the box frame 400.

[0055] In other possible embodiments, a protrusion is provided on the circumferential side of the locking rod 220. When the locking rod 220 rotates in the circumferential direction, the locking rod 220 uses the protrusion to push the elastic arm 212 outward, and the elastic arm 212 is converted from a contracted state to an expanded state, so that the locking portion 213 can be embedded in the locking groove 125. When the protrusion on the circumferential side of the elastic arm 212 does not push up the elastic arm 212, the elastic arm 212 is in a contracted state, and the locking portion 213 is separated from the locking groove 125.

[0056] Instead of the above-mentioned arrangement of the locking portion 213, in other possible embodiments, the side of the plug-in portion 211 is provided with a guide hole connected to the movable channel 2111 along its radial direction, and the locking portion 213 is a ball movably arranged in the guide hole, and the inner side of the ball is in conflict with the locking rod 220. Specifically, during the axial sliding process or circumferential rotation process of the locking rod 220 in the movable channel 2111, the side wall of the locking rod 220 acts on the inner side of the ball, so that the ball bulges outward, and then the locking portion 213 remains embedded in the locking groove 125. When the side wall of the locking rod 220 releases the force on the ball, the ball can shrink toward the movable channel 2111, thereby releasing the axial restriction between the plug-in portion 211 and the rotating seat 120, and then the display module 300 can be easily removed from the box frame 400.

[0057] In some embodiments, reference Figures 2 to 4If the locking rod 220 is axially slidably arranged in the movable channel 2111, the locking assembly 200 also includes an elastic member 230 arranged on the locking seat 210, and the elastic member 230 is used to provide an elastic force toward the rotating seat 120 to the locking rod 220 so that the locking rod 220 can be reset to the locking position; wherein, when the locking rod 220 moves to the locking position, the locking rod 220 keeps the locking portion 213 embedded in the locking groove 125.

[0058] Specifically, the bottom of the locking seat 210 away from the rotating seat 120 is provided with a clearance opening 2113, and the clearance opening 2113 is connected to the active channel 2111. The locking seat 210 is connected to the bottom shell 310 of the display module 300 (refer to Figure 7 ), the elastic member 230 may be a spring disposed inside the rotating seat 120. One end of the elastic member 230 abuts against the bottom shell 310 of the display module 300, and the other end abuts against one end of the locking rod 220 close to the opening 2113, thereby, the elastic member 230 provides elastic force to the locking rod 220 toward the fixed seat 110. When the locking rod 220 is not subjected to an external force, the locking rod 220 slides toward the rotating seat 120 to a locking position under the action of the elastic member 230, at which time, the locking rod 220 restricts the locking portion 213 from contracting, so that the locking portion 213 remains in the locking groove 125, thereby allowing the display module 300 to be firmly assembled on the box frame 400.

[0059] In a specific application process, when the staff drives the locking rod 220 to shrink toward the bottom shell 310 of the display module 300, the outer protrusion 221 of the locking rod 220 slides to the inner side of the first extension section 2121, thereby releasing the restriction on the elastic arm 212. As a result, each elastic arm 212 can be elastically deformed inward, and the locking portion 213 elastically shrinks inward, so that the locking portion 213 can be separated from the locking groove 125, and then the axial restriction between the locking seat 210 and the rotating seat 120 can be released, and the display module 300 is more convenient to disassemble. When the staff stops applying force to the locking rod 220, the elastic member 230 pushes the locking rod 220 to move toward the rotating seat 120, and the locking rod 220 is reset to the locking position under the action of the elastic member 230. At this time, the outer protrusion 221 of the locking rod 220 moves to the inner side of the second extension section 2122. Therefore, each elastic arm 212 cannot be elastically deformed inward under the restriction of the locking rod 220, and the locking portion 213 on the elastic arm 212 remains in a convex state, so that it can be used to slide into the locking groove 125 along the guide groove 124, thereby achieving a stable assembly of the display module 300 on the box frame 400.

[0060] In some embodiments, reference Figure 1 and Figure 3The plug-in end of the plug-in portion 211 is provided with a first extension opening 2112, and the end of the rotating seat 120 away from the plug-in port 122 is provided with a second extension opening 123 connected to the fixed channel 121. When the plug-in portion 211 is inserted into the fixed channel 121, the plug-in end of the plug-in portion 211 is located at or close to the second extension opening 123. The lock rod 220 is provided with a pressing portion 222 connected to the outer protrusion 221, and the pressing portion 222 is provided through the first extension opening 2112 and the second extension opening 123, and extends to the outer bottom of the fixed seat 110.

[0061] In a specific application process, if the display module 300 needs to be disassembled, the staff pushes the pressing portion 222 from the back side of the box frame 400 toward the display module 300, and the locking rod 220 overcomes the elastic force of the elastic member 230 and moves toward the display module 300, and the outer protrusion 221 of the locking rod 220 slides to the inner side of the first extension section 2121, thereby releasing the restriction on the elastic arm 212. As a result, each elastic arm 212 can be elastically deformed inwardly, and the locking portion 213 is elastically contracted inwardly, so that the locking portion 213 can be separated from the locking groove 125, and then the axial restriction between the locking seat 210 and the rotating seat 120 can be released, and the display module 300 can be disassembled more conveniently. If it is necessary to re-assemble the locking seat 210 on the rotating seat 120, the staff stops acting on the pressing portion 222, and the locking rod 220 returns to the locking position under the action of the elastic member 230. The protruding portion 221 moves to the inner side of the second extension section 2122, and the locking portion 213 remains in a convex state, so that the locking portion 213 can slide into the locking groove 125 along the guide groove 124 to realize the assembly of the display module 300 on the box frame 400.

[0062] In some embodiments, reference Figure 1 , Figure 6 and Figure 7The locking rod 220 is made of a magnetic material, such as a metal material, such as iron, stainless steel, etc. The locking rod 220 can be moved toward the clearance opening 2113 by the magnetic attraction force from the clearance opening 2113. Specifically, the clearance opening 2113 is arranged to face the display module 300, and the external magnetic attraction component is placed on the front of the display module 300 and is located at a position corresponding to the clearance opening 2113. Then, the magnetic attraction component generates a magnetic attraction force toward the display module 300 to the locking rod 220 through the clearance opening 2113, and the locking rod 220 overcomes the elastic force of the elastic component 230 and moves toward the display module 300, and the outer protrusion 221 of the locking rod 220 slides to the inner side of the first extension section 2121, thereby releasing the restriction on the elastic arm 212. Thus, each elastic arm 212 can be elastically deformed inward, and the locking portion 213 can be elastically contracted inward, so that the locking portion 213 can be separated from the locking groove 125, and then the axial restriction between the locking seat 210 and the rotating seat 120 can be released, and the display module 300 is more convenient to disassemble. If the magnetic attraction member stops magnetically attracting the locking rod 220, the locking rod 220 returns to the locking position under the action of the elastic member 230, and the outer protrusion 221 moves to the inner side of the second extension section 2122, and the locking portion 213 remains in the outer protrusion state, so that the locking portion 213 can slide into the locking groove 125 along the guide groove 124, so that the display module 300 can be firmly assembled on the box frame 400.

[0063] In some embodiments, reference Figure 1 and Figure 3 , the locking rod 220 can be moved toward the clearance opening 2113 by the negative pressure from the clearance opening 2113. Specifically, the clearance opening 2113 is arranged facing the display module 300, and the suction cup of the external negative pressure source is placed on the front of the display module 300 and located at the position corresponding to the clearance opening 2113; at the same time, the display module 300 is also provided with a suction hole 320, and the suction hole 320 is located between the suction cup of the negative pressure source and the clearance opening 2113. Then, the negative pressure source extracts the air in the installation cavity through the suction hole 320. At this time, the locking rod 220 overcomes the force of the second elastic member 230 under the action of atmospheric pressure and moves toward the display module 300, and the outer protrusion 221 of the locking rod 220 slides to the inner side of the first extension section 2121, thereby releasing the restriction on the elastic arm 212. Thus, each elastic arm 212 can be elastically deformed inwardly, and the locking portion 213 can be elastically contracted inwardly, so that the locking portion 213 can be separated from the locking groove 125, and then the axial restriction between the locking seat 210 and the rotating seat 120 can be released, and the display module 300 is more convenient to disassemble. If the negative pressure source stops working, the locking rod 220 returns to the locking position under the action of the elastic member 230, and the outer protrusion 221 moves to the inner side of the second extension section 2122, and the locking portion 213 remains in the outer protrusion state, so that the locking portion 213 can slide into the locking groove 125 along the guide groove 124, so that the display module 300 can be firmly assembled on the box frame 400.

[0064] The present application also discloses a display device, referring to Figure 1 , Figure 6 and Figure 7 , including a box frame 400, a display module 300 and the above-mentioned locking mechanism, wherein the fixing seat 110 is assembled and connected or integrated with the box frame 400, and the locking seat 210 is assembled and connected or integrated with the bottom shell 310 of the display module 300.

[0065] Specifically, during the assembly process of the display module 300 and the box frame 400, the locking portion 213 is aligned with the guide groove 124 at the end of the plug-in port 122, the plug-in portion 211 extends from the plug-in port 122 into the fixed channel 121, and the locking portion 213 slides into the locking groove 125 along the guide groove 124 and is retained in the locking groove 125, thereby assembling and connecting the locking seat 210 to the fixed assembly 100, thereby conveniently assembling the display module 300 to the box frame 400. In the process of inserting the plug-in portion 211 into the fixed channel 121, since the guide groove 124 is extended from the plug-in port 122 toward the other end of the fixed channel 121, the guide groove 124 is also circumferentially extended, so the locking portion 213 drives the rotating seat 120 to rotate in the positive direction during the sliding process along the guide groove 124, and the rotating seat 120 pulls the elastic energy storage member 130 to be stretched in the positive direction, and the elastic energy storage member 130 is effectively stored. When the locking portion 213 moves to the position of the locking groove 125, the elastic energy storage member 130 begins to release force to provide a circumferential force in the reverse direction to the rotating seat 120. As a result, the rotating seat 120 rotates in the reverse direction under the drive of the elastic energy storage member 130, so that the locking portion 213 slides into the locking groove 125, thereby realizing the fixed assembly connection of the locking seat 210 to the fixed seat 110. Accordingly, the display module 300 is assembled on the box frame 400.

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.
