Description

Technical Field

[0001] This utility model relates to the field of display device technology, and in particular to a connecting latch and display device. Background Technology

[0002] In related technologies, display devices include a frame and display units. The display units include several interconnected display modules, and each display module is mounted on the frame by a locking mechanism.

[0003] When one of the display modules needs to be repaired, the staff uses tools to unlock the locking mechanism from the back of the frame, so that the display module can be disassembled and repaired, that is, the display module can be maintained. During the disassembly process, the operation of the locking mechanism is relatively cumbersome. As can be seen from the above, the display module and the frame adopt the above connection structure, which makes the disassembly of the display module more troublesome, resulting in more troublesome maintenance of the display module. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a connecting latch and display device to facilitate the disassembly of the display module for easier maintenance.

[0005] In a first aspect, embodiments of this application provide a connecting latch, including:

[0006] A fixing component includes a connector and a pusher. The connector has a connection channel, and the connection channel forms an operation port and a insertion port at both ends of the connector. The pusher is disposed at the operation port.

[0007] The locking assembly includes a locking seat and a locking rod. The locking seat has a plug-in portion that extends into the connection channel through the plug-in interface. The plug-in portion has a guide channel that passes through the plug-in end of the plug-in portion. The locking rod is slidably disposed in the guide channel and abuts against the pusher.

[0008] The pusher is configured to be operable to push the locking rod from a first position to a second position. When the locking rod is in the first position, the locking rod keeps the plug-in portion engaged with the latch seat. When the locking rod is in the second position, the locking rod engages with the latch seat and releases the holding force that keeps the plug-in portion engaged with the connecting seat.

[0009] According to some embodiments of the present invention, the locking assembly further includes a first elastic member disposed on the locking seat. When the pushing member releases the force on the locking rod, the second elastic member is used to reset the locking rod to the first position.

[0010] According to some embodiments of the present invention, the first elastic element is sleeved on the locking rod and abuts against the locking seat and the locking rod in the axial direction of the guide channel.

[0011] According to some embodiments of the present invention, the locking rod is provided with a clearance channel along its own axial direction, and the side wall of the locking rod is provided with a clearance hole communicating with the clearance channel;

[0012] The locking assembly further includes a first locking member, which is movably disposed in the clearance hole, and the pusher is provided with a push rod that extends into the clearance channel and abuts against the first locking member;

[0013] The guide channel has a limiting groove on its channel wall. When the locking rod is in the first position, the first locking member is offset from the limiting groove, and the top rod can push the locking rod from the first position to the second position through the first locking member. When the locking rod is in the second position, the first locking member coincides with the limiting groove, and the top rod pushes the first locking member into the limiting groove.

[0014] According to some embodiments of the present invention, two or more first locking members are provided and are located sequentially in the circumferential direction of the locking rod; wherein, when the locking rod is in the second position, the top rod is located between each of the first locking members, and the first locking members are used to apply a frictional force to the top rod to restrict the sliding of the locking rod.

[0015] According to some embodiments of the present invention, the insertion end of the top rod is provided in a spike shape.

[0016] According to some embodiments of the present invention, the limiting groove is provided with a limiting surface that restricts the movement of the first locking member toward the insertion end of the insertion part, and the limiting surface is provided as a guide slope or a guide arc surface.

[0017] According to some embodiments of the present invention, the side of the plug portion is provided with a guide hole communicating with the guide channel, and the locking assembly further includes a second locking member, which is movably disposed in the guide hole;

[0018] The locking rod has a clearance groove on its side wall. When the locking rod is in the first position, the guide hole is offset from the clearance groove, and the outer peripheral wall of the locking rod abuts against the second locking member, so that the second locking member has a locking part exposed in the plug-in portion, which is used to engage with the connecting seat. When the locking rod is in the second position, the guide hole coincides with the clearance groove, and the second locking member can move toward the clearance groove to be hidden in the side of the plug-in portion.

[0019] According to some embodiments of the present invention, the fixing component further includes a mounting base and an elastic energy storage component. The connecting seat is rotatably disposed on the mounting base, the pushing component is disposed on the mounting base, and the elastic energy storage component is connected to the mounting base and the connecting seat for storing force when the connecting seat rotates circumferentially.

[0020] The insertion part is provided with a retractable locking part. The inner peripheral wall of the connecting channel is provided with a second guide groove and a locking groove that extend circumferentially and face opposite directions. One end of the second guide groove is connected to the insertion interface, and the other end extends toward the operating port and is connected to the locking groove. When the locking part slides along the second guide groove, the connecting seat is adapted to rotate in one circumferential direction to allow the elastic energy storage member to store energy. When the locking part moves to the locking groove, the elastic energy storage member drives the connecting seat to rotate in another circumferential direction to allow the locking part to slide into the locking groove.

[0021] Secondly, embodiments of this application provide a display device, including:

[0022] Box frame and display module;

[0023] The aforementioned connecting latch, wherein the connecting seat is connected to the frame, and the latch seat is assembled or integrated with the bottom shell of the display module.

[0024] As can be seen from the above technical solutions, the embodiments of this application have the following advantages: In specific applications, when the display module is assembled on the frame, the pushing component does not push the locking rod to move, and the locking rod is in the first position. At this time, the locking rod keeps the plug-in part engaged with the locking seat, thereby ensuring that the display module is stably assembled on the frame. When it is necessary to remove the display module from the frame, the operator rotates or presses the pushing component, and the pushing component pushes the locking rod to retract in the direction of the guide channel. The locking rod slides from the first position to the second position. At this time, the locking rod releases the retaining force of the plug-in part engaging with the connecting seat, and the plug-in part can be easily pulled out from the connecting channel, thereby making it easy to remove the display module from the frame.

[0025] It should be noted that when the locking rod slides to the second position, it engages with the inner wall of the locking seat, thus keeping the locking rod in the second position. Therefore, when the display module is removed from the frame, the locking rod is effectively prevented from returning to the first position, so that the locking rod does not have the retaining force to engage with the connecting seat, thereby ensuring the convenience of disassembling the display module.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0043] The present invention will now be described in further detail with reference to the accompanying drawings.

[0044] Please see Figures 1 to 3 This invention provides a connecting latch as an embodiment of the present invention. The connecting latch is applied to a display device, and the description is based on its application to a display device, but it is not limited to use only in display devices. (Refer to...) Figure 9The connecting latch includes a fixing component 100 and a latching component 200. The fixing component 100 is fixed to the display device frame 300, and the latching component 200 is connected to the bottom shell 410 of the display module 400 of the display device. The latching component 200 is connected to the fixing component 100, thereby assembling the display module 400 onto the frame 300.

[0045] Specifically, the fixing component 100 includes a connecting base 110 and a pushing member 120. The connecting base 110 is provided with a connecting channel 111, and the connecting channel 111 forms an operation port 1111 and a plug-in interface 1112 at both ends of the connecting base 110 (see reference). Figure 9 The pusher 120 is disposed at the operating port 1111. For example, the pusher 120 can be a button or a knob disposed at the operating port 1111 for operation by the operator. The locking assembly 200 includes a locking seat 210 and a locking rod 220. The locking seat 210 is provided with a plug-in portion 211 that is inserted into the connecting channel 111 through the plug-in interface 1112. The plug-in portion 211 is provided with a guide channel 212 along its own axial direction, and the guide channel 212 passes through the insertion end 2111 of the plug-in portion 211. The locking rod 220 is slidably disposed in the guide channel 212 and abuts against the pusher 120. The pusher 120 is configured to be operable to push the locking lever 220 from a first position to a second position. When the locking lever 220 is in the first position, the locking lever 220 keeps the plug portion 211 engaged with the connecting seat 110. When the locking lever 220 is in the second position, the locking lever 220 engages with the latch seat 210 and releases the holding force of the plug portion 211 engaged with the connecting seat 110.

[0046] In practical applications, when the display module 400 is assembled on the frame 300, the pushing member 120 does not push the locking rod 220 to move, and the locking rod 220 is in the first position. At this time, the locking rod 220 keeps the plug-in part 211 engaged with the locking seat 210, thereby ensuring that the display module 400 is stably assembled on the frame 300. When it is necessary to remove the display module 400 from the frame 300, the operator rotates or presses the pushing member 120, and the pushing member 120 pushes the locking rod 220 to retract towards the guide channel 212. The locking rod 220 slides from the first position to the second position. At this time, the locking rod 220 releases the retaining force of the plug-in part 211 engaged with the connecting seat 110, and the plug-in part 211 can be easily pulled out from the connecting channel 111, thereby making it easy to remove the display module 400 from the frame 300.

[0047] It should be noted that when the locking lever 220 slides to the second position, the locking lever 220 engages with the inner wall of the locking seat 210, thereby keeping the locking lever 220 in the second position. Therefore, when the display module 400 is removed from the frame 300, the locking lever 220 is effectively prevented from returning to the first position, so that the locking lever 220 does not have the retaining force of the plug 211 engaging with the connecting seat 110, thus ensuring the convenience of disassembling the display module 400.

[0048] In some embodiments, refer to Figure 3 and Figure 4 The locking assembly 200 also includes a first elastic element 230, which is disposed on the locking seat 210 and is used to provide a spring force to the locking rod 220 toward the connecting seat 110. When the pusher 120 is not acting on the locking lever 220, the locking lever 220 is held in the first position by the action of the first elastic member 230. At this time, the locking lever 220 keeps the plug-in portion 211 engaged with the connecting seat 110, thereby ensuring that the display module 400 is stably connected to the frame 300. Alternatively, when the pusher 120 is not acting on the locking lever 220, for example, when the latch seat 210 is separated from the connecting seat 110, the first elastic member 230 pushes the locking lever 220 to slide toward the insertion end 2111 of the plug-in portion 211. The locking lever 220 is reset from the second position to the first position, and the plug-in portion 211 can be used to be plugged back into the connecting channel 111 of the connecting seat 110 to engage with the connecting seat 110. This will be explained in detail later.

[0049] To facilitate the assembly of the first elastic element 230, in some specific embodiments, the guide channel 212 has a stepped surface 2121 on its inner side near the insertion end 2111, with the stepped surface 2121 facing the port of the insertion end 2111. Meanwhile, the locking rod 220 has an extended end extending from the insertion end 2111, and an annular groove 221 is provided on the side of the extended end. A fixing ring 240 is fitted and fixed within the annular groove 221. The first elastic element 230 can be a spring, fitted onto the outer side of the locking rod 220. One end of the first elastic element 230 near the insertion part 211 abuts against the stepped surface 2121, and the other end abuts against the fixing ring 240. Thus, the first elastic element 230 axially abuts between the locking rod 220 and the locking seat 210, and provides a spring force to the locking rod 220 toward the connecting seat 110 through the fixing ring 240, enabling the locking rod 220 to return from the second position to the first position toward the connecting seat 110.

[0050] It is understandable that by adopting the above-described assembly method, the first elastic element 230, the locking seat 210, the first elastic element 230, and the locking rod 220 can be easily assembled together, thus the locking assembly 200 is assembled as a whole, which allows the locking assembly 200 to be easily assembled onto the bottom shell 410 of the display module 400; or, the locking seat 210, the first elastic element 230, and the locking rod 220 are assembled as a whole, allowing the operator to easily remove the locking assembly 200 from the bottom shell 410 of the display module 400.

[0051] In other possible embodiments, the first elastic member 230 may be disposed at the bottom of the latch seat 210. One end of the first elastic member 230 abuts against the bottom shell 410 of the display module 400, and the other end abuts against the tail of the locking rod 220. Thus, the first elastic member 230 may provide an elastic force to the locking rod 220 toward the connecting seat 110, so that the locking rod 220 can be reset from the second position to the first position.

[0052] In some embodiments, refer to Figure 3 and Figure 4 The locking rod 220 has a clearance channel 222 along its axial direction, which extends through the end of the locking rod 220 near the connecting seat 110. The side wall of the locking rod 220 has a clearance hole 223 communicating with the clearance channel 222. The locking assembly 200 also includes a first locking member 250, which can be a ball bearing, but is not limited to ball bearings. For example, the first locking member 250 can also be a rod-shaped body with rounded corners at both ends. The first locking member 250 is movably disposed in the clearance hole 223 and can at least partially reside within the clearance channel 222. The inner side of the pusher 120 has a push rod 121, which extends from the end of the locking rod 220 into the clearance channel 222 and abuts against the first locking member 250.

[0053] The guide channel 212 has a limiting groove 214 on its channel wall. When the locking rod 220 is in the first position, the first locking member 250 is offset from the limiting groove 214, and part of the first locking member 250 is located in the clearance channel 222. Thus, the push rod 121 abuts against the first locking member 250, and the push rod 121 can push the locking rod 220 from the first position to the second position through the first locking member 250 (see reference). Figure 5 and Figure 6 When the locking rod 220 is in the second position, the first locking member 250 coincides with the limiting groove 214. At this time, the first elastic member 230 provides sufficient resistance to the locking rod 220, and the push rod 121 cannot continue to push the locking rod 220 towards the guide channel 212 through the first locking member 250. At the same time, instead of pushing the locking rod 220 towards the inside of the guide channel 212, the push rod 121 pushes the first locking member 250 into the limiting groove 214 (see reference). Figure 7Simultaneously, the push rod 121 passes over the first locking member 250, and the side wall of the push rod 121 abuts against the inner side of the first locking member 250, thereby keeping the first locking member 250 within the limiting groove 214. (See reference...) Figure 7 When the push rod 121 separates from the first locking member 250, the push rod 121 loses its restriction on the first locking member 250, and the first locking member 250 can move toward the relief channel 222. Therefore, the locking rod 200 can return to the first position under the action of the first elastic member 230.

[0054] It should be noted that, referring to Figure 7 When the locking rod 220 slides to the second position, under the restriction of the top rod 121, at least part of the first locking member 250 is located in the clearance hole 223 of the locking rod 220, and the other part is located in the limiting groove 214 of the plug-in part 211. With this configuration, the plug-in part 211 restricts the locking rod 220 from moving toward the pushing member 120 under the action of the first elastic member 230 through the first locking member 250, thereby keeping the locking rod 220 in the second position to facilitate the disassembly of the display module 400.

[0055] Furthermore, two or more first locking members 250 are provided, and the locking rod 220 has a number of clearance holes 223 in its circumferential direction equal to the number of first locking members 250. The first locking members 250 are movably disposed in the clearance holes 223. When the locking rod 220 is in the second position, the push rod 121 is located between each of the first locking members 250. The first locking members 250 are used to apply a sufficiently large frictional force to the push rod 121 to limit the push rod 121 from sliding towards the push member 120 under the action of external elastic force. For example, if there are two first locking members 250, when the push rod 121 pushes the two first locking members 250 into the limiting groove 214, the push rod 121 abuts against the inner sides of the two first locking members 250. At this time, the frictional force of the two first locking members 250 on the push rod 121 is greater than the elastic restoring force of the push member 120, that is, the force of the second elastic member 150 described below, so that the push rod 121 can be kept between the inner sides of the first locking members 250, thereby keeping the first locking members 250 embedded in the limiting groove 214, making it easier to disassemble the display module 400.

[0056] Furthermore, the insertion end 1211 of the push rod 121 is provided in a spike-like shape. It can be understood that when the push rod 121 pushes the locking rod 220 to the second position via the first locking member 250, due to the spike-like shape of the insertion end 1211 of the push rod 121, the frictional force between the push rod 121 and the first locking member 250 is relatively small, and the first locking member 250 is precisely located at the position of the limiting groove 214 (refer to...). Figure 5 and Figure 6Therefore, if the insert end 1211 of the push rod 121 continues to push the first locking member 250 toward the inner side of the guide channel 212, the insert end 1211 of the push rod 121 cannot maintain its contact with the surface of the first locking member 250. Therefore, as the push rod 121 continues to move toward the clearance channel 222, the insert end 1211 of the push rod 121 can smoothly push the first locking member 250 toward the limiting groove 214 using the inclined surface at its end, so that the first locking member 250 is embedded in the limiting groove 214 (see reference). Figure 7 This ensures that the locking lever 220 remains in the second position. Correspondingly, the locking lever 220 releases the retaining force that engages the plug 211 with the connector 110, so as to facilitate the disassembly of the display module 400.

[0057] In order for the first locking member 250 to slide from the second position to the first position along with the locking lever 220, in some embodiments, reference is made to... Figure 3 and Figure 4 The limiting groove 214 is provided with a limiting surface 2141, which is used to restrict the movement of the first locking member 250 toward the insertion end 2111 of the insertion part 211. The limiting surface 2141 is provided as a guide slope or as a guide arc surface.

[0058] Understandably, when the display module 400 is disassembled, the plug-in portion 211 separates from the connecting seat 110. At this time, the push rod 121 separates from the first locking member 250, thereby releasing the restriction of the push rod 121 on the first locking member 250. The first elastic member 230 provides a sufficiently large axial force to the locking rod 220, causing the locking rod 220 to drive the first locking member 250 to slide along the limiting surface 2141. It should be noted that, without the restriction of the push rod 121, the first locking member 250 slides into the clearance channel 222, thereby ensuring that the locking rod 220 slides towards the outside of the plug-in portion 211 under the action of the first elastic member 230. The limiting surface 2141 is configured as a guide slope or a guide arc surface. With this configuration, when the first elastic member 230 pushes the locking rod 220 to slide, the limiting surface 2141 can gradually push the first locking member 250 to slide into the clearance channel 222, thereby avoiding interference between the first locking member 250 and the insertion part 211.

[0059] In some embodiments, refer to Figure 3 and Figure 4The side of the insertion part 211 is provided with a guide hole 213 communicating with the guide channel 212. The locking assembly 200 also includes a second locking member 260. The second locking member 260 can be a ball bearing, but is not limited to ball bearings. For example, the second locking member 260 can also be a rod-shaped body with rounded ends. The second locking member 260 is movably disposed in the guide hole 213. The side wall of the locking rod 220 is provided with a relief groove 224. When the locking rod 220 is in the first position, the guide hole 213 and the relief groove 224 are misaligned, and the outer peripheral wall of the locking rod 220 abuts against the second locking member 260, so that the second locking member 260 has a locking part 261 exposed in the insertion part 211. The locking part 261 is used to engage with the connecting seat 110 (see reference). Figure 5 When the locking rod 220 is in the second position, the guide hole 213 coincides with the relief groove 224, and the second locking member 260 can move into the relief groove 224 to be hidden in the side of the insertion part 211 (see reference). Figure 6 and Figure 7 ).

[0060] In practical applications, refer to Figure 5 The locking seat 210 is connected to the bottom shell 410 of the display module 400. Under the action of the first elastic member 230, the locking rod 220 is located in the first position. The clearance groove 224 on the locking rod 220 is offset from the guide hole 213. The outer peripheral wall of the locking rod 220 abuts against the side of the second locking member 260 near the guide channel 212. Therefore, under the restriction of the locking rod 220, part of the second locking member 260 is exposed outside the plug-in portion 211, thereby firmly engaging with the inner side of the connecting channel 111, thus making the display module 400 securely assembled on the frame 300. (Refer to...) Figure 6 and Figure 7 If it is necessary to remove the display module 400 from the frame 300, the pusher 120 pushes the locking rod 220 to slide into the guide channel 212 and slides to the second position. The clearance groove 224 on the side wall of the locking rod 220 coincides with the guide hole 213. The second locking member 260 can move towards the clearance groove 224. Thus, the locking rod 220 releases the restriction on the second locking member 260. The second locking member 260 can move towards the clearance groove 224. The second locking member 260 is hidden in the side of the plug-in part 211, thereby releasing the axial restriction between the latch seat 210 and the fixed seat. The latch seat 210 and the fixed seat can be separated, so that the display module 400 can be easily removed from the frame 300.

[0061] Instead of the aforementioned locking portion 261, in other possible embodiments, the insertion portion 211 is provided with a plurality of elastic arms (not shown in the figure) in sequence in its circumferential direction. Each elastic arm can elastically deform outward or inward, and the locking portion 261 is a protrusion provided on the outer side of the elastic arm. The locking rod 220 is movably disposed between the elastic arms. During the axial sliding process between the elastic arms, the locking rod 220 controls the elastic arms to expand or contract, thereby controlling the locking portion 261 to protrude outward or contract inward, thereby releasing the axial constraint between the insertion portion 211 and the locking seat 210.

[0062] In some embodiments, refer to Figure 4 , Figure 8 and Figure 9 The fixing component 100 also includes a mounting base 130, a button base 140, and a second elastic element 150. The mounting base 130 is assembled or integrated with the frame 300 (see reference). Figure 10 The button base 140 is connected to the mounting base 130, and one end of the connecting base 110 is integrally connected or assembled with the mounting base 130. When the connecting base 110 and the mounting base 130 are assembled, they can be fixedly assembled or rotated, depending on actual needs. The button base 140 is used to hold the end of the connecting base 110 mounted on the mounting base 130. The inner side of the button base 140 has a pressing channel 141, one end of which communicates with the operation port 1111 of the connecting channel 111. The pusher 120 is slidably disposed within the pressing channel 141 of the button base 140, with a portion of the pusher 120 exposed at the end of the button base 140 away from the connecting base 110, to facilitate pressing by the operator. The second elastic member 150 is disposed in the pressing channel 141 of the button seat 140. The inner end of the second elastic member 150 abuts against the button seat 140, and the outer end abuts against the inner side of the push member 120. Thus, the second elastic member 150 is used to provide an outward restoring force to the push member 120.

[0063] Understandably, when the operator presses the pusher 120 inward, the pusher 120 drives the push rod 121 to slide into the clearance channel 222, thereby pushing the locking rod 220 from the first position to the second position to facilitate the disassembly of the display module 400. After the display module 400 is disassembled, the pusher 120 moves towards the bottom of the mounting base 130 under the action of the second elastic member 150, thereby resetting to the initial position in preparation for pushing the locking rod 220 again.

[0064] In some embodiments, the fixing assembly 100 further includes an elastic energy storage member 160, which 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 insertion portion 211 is provided with a retractable locking portion 261, 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 circumferentially extending and oppositely oriented second guide groove 1113 and a locking groove 1114. One end of the second guide groove 1113 communicates with the insertion interface 1112, and the other end extends toward the protrusion and connects with the locking groove 1114. When the locking part 261 slides along the second guide groove 1113, the connecting seat 110 is adapted to rotate in a circumferential direction to allow the elastic energy storage member 160 to store energy; when the locking part 261 moves to the locking groove 1114, the elastic energy storage member 160 drives the connecting seat 110 to rotate in another circumferential direction to allow the locking part 261 to slide into the locking groove 1114.

[0065] The guide groove 1113 is spirally disposed on the inner peripheral 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 peripheral wall of the connecting channel 111; and the locking groove 1114 is spirally disposed on the inner peripheral wall of the connecting channel 111, and the spiral angle of the guide groove 1113 is greater than or equal to 20 degrees.

[0066] Specifically, during the assembly process of the display module 400 and the frame 300, the locking part 261 is aligned with the port of the insertion interface 1112 of the second guide groove 1113, the insertion part 211 extends from the insertion interface 1112 into the connection channel 111, and the locking part 261 slides into the locking groove 1114 along the second guide groove 1113 and remains in the locking groove 1114, thereby assembling the locking seat 210 onto the fixing component 100, and thus conveniently assembling the display module 400 onto the frame 300. During the insertion of the plug-in part 211 into the connection channel 111, the second guide groove 1113 extends circumferentially from the plug-in interface 1112 toward the other end of the connection channel 111. Therefore, as the locking part 261 slides along the second guide groove 1113, it drives the connecting seat 110 to rotate in the forward direction. The connecting seat 110 pulls the elastic energy storage member 160 to be extended in the forward direction, effectively storing energy. When the locking part 261 moves to the position of the locking groove 1114, the elastic energy storage member 160 begins to release force, providing a reverse circumferential force to the connecting seat 110. Consequently, the connecting seat 110 rotates in the reverse direction under the drive of the elastic energy storage member 160, causing the locking part 261 to slide into the locking groove 1114. This achieves a fixed assembly connection of the locking seat 210 to the mounting base 130, and correspondingly, the display module 400 is assembled onto the frame 300.

[0067] It should be emphasized that the locking groove 1114 needs to lock the latching part 261. When the locking groove 1114 extends circumferentially, its axial extension is small or non-extensional, so that the locking groove 1114 can lock the latching part 261. This application effectively realizes that the latching part 261 can slide into the locking groove 1114 by setting the elastic energy storage member 160; moreover, after the elastic energy storage member 160 releases the force, it holds the position of the connecting seat 110 to restrict the rotation of the connecting seat 110, thereby keeping the latching part 261 in the locking groove 1114. Thus, the latching seat 210 is stably assembled on the fixing assembly 100.

[0068] In other possible embodiments, a limiting protrusion (not shown in the figure) is provided on the inner side of the connection channel 111 near the plug interface 1112. The limiting protrusion can also connect the locking seat 210 to the connection seat 110 by limiting the locking part 261, so that the display module 400 can be assembled on the frame 300.

[0069] To facilitate the installation of the elastic energy storage element 160, in some embodiments, refer to Figure 3 and Figure 8 The mounting base 130 has a surrounding plate portion 131 and an end cap portion 132, with the surrounding plate portion 131 connected to the periphery of the end cap portion 132. A connecting seat 110 is rotatably inserted through the center of the end cap portion 132, forming an annular enclosure space between the outer peripheral surface of the connecting seat 110 and the inner peripheral surface of the surrounding plate portion 131. Simultaneously, the bottom of the connecting seat 110 has a flange portion 112 that expands outwards, corresponding to the end cap portion 132. The inner side of the end cap portion 132 has a first pin 1321 extending toward the flange portion 112, and the inner side of the flange portion 112 has a second pin 113 extending toward the end cap portion 132. The first pin 1321 and the second pin 113 are spaced apart in the circumferential direction of the enclosure space. The elastic energy storage component 160 can be a tension spring. The elastic energy storage component 160 is arc-shaped and set in the enclosed space. One end of the elastic energy storage component 160 is hooked on the first pin 1321 and the other end is hooked on the second pin 113. Thus, the elastic energy storage component 160 is conveniently connected to the periphery between the mounting base 130 and the connecting seat 110, so that it can effectively store energy when the connecting seat 110 rotates.

[0070] This application also discloses a display device, including a frame 300, a display module 400 and the above-mentioned connecting latch, a connecting seat 110 connected to the frame 300, and a latch seat 210 assembled or integrated with the bottom shell 410 of the display module 400.

[0071] Understandably, the display device uses the aforementioned connecting latch. When the display module 400 is assembled on the frame 300, the pushing member 120 does not push the locking lever 220 to move, and the locking lever 220 is in the first position. At this time, the locking lever 220 keeps the plug-in part 211 engaged with the latch seat 210, thereby ensuring that the display module 400 is securely assembled on the frame 300. When it is necessary to remove the display module 400 from the frame 300, the operator rotates or presses the pushing member 120. The pushing member 120 pushes the locking lever 220 to retract towards the guide channel 212, and the locking lever 220 slides from the first position to the second position. At this time, the locking lever 220 releases the retaining force of the plug-in part 211 engaged with the connecting seat 110, and the plug-in part 211 can be easily pulled out from the connecting channel 111, thereby allowing the display module 400 to be easily removed from the frame 300.

[0072] It should be noted that when the locking lever 220 slides to the second position, the locking lever 220 engages with the inner wall of the locking seat 210, thereby keeping the locking lever 220 in the second position. Therefore, when the display module 400 is removed from the frame 300, the locking lever 220 is effectively prevented from returning to the first position, so that the locking lever 220 does not have the retaining force of the plug 211 engaging with the connecting seat 110, thus ensuring the convenience of disassembling the display module 400.

[0073] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
