Description

Technical Field

[0001] This invention relates to the technical field of display devices, and more particularly to a locking mechanism and a display device. Background Technology

[0002] In related technologies, display devices include a frame and display units. Each display unit comprises several interconnected display modules, which are mounted on the frame via a locking mechanism. When maintenance is required on one of the display modules, workers use tools to unlock the locking mechanism from the back of the frame, allowing for disassembly and repair of the display module—essentially post-maintenance. The operation of the locking mechanism during disassembly is quite cumbersome. As can be seen, the aforementioned connection structure between the display module and the frame makes disassembly of the display module difficult, leading to complicated maintenance. Summary of the Invention

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a locking mechanism and a display device, which facilitates the disassembly of the display module, thereby simplifying the maintenance of the display module.

[0004] In a first aspect, embodiments of this application provide a locking mechanism, including:

[0005] A locking assembly includes a locking seat and a locking member. The locking seat has a plug-in portion, and the locking member is movably disposed on the side of the plug-in portion and is at least partially exposed on the outside of the plug-in portion.

[0006] A fixing component includes a fixing base and a pushing member, wherein the fixing base is provided with a connecting channel and a plug-in interface for the plug-in portion to extend into the connecting channel, the locking member is engaged with the inner side of the connecting channel, and the pushing member is slidably disposed in the connecting channel so as to act on the locking member;

[0007] The pusher can be pushed to retract the locking member, thereby releasing the axial restriction between the insertion part and the fixing seat.

[0008] According to some embodiments of the present invention, the locking assembly further includes:

[0009] The first elastic element is used to reset the pusher away from the insertion interface;

[0010] The movable rod has a guide channel and a connected extension port in the insertion part. The movable rod is slidably disposed in the guide channel. One end of the movable rod extends into the connecting channel through the extension port to abut against the pusher. The side of the movable rod has a clearance groove to make way for the locking member.

[0011] The second elastic element is disposed in the locking seat and is used to act on the movable rod in the direction toward the fixed seat;

[0012] When the pusher pushes the recess of the movable rod to coincide with the locking member, the locking member can move toward the recess to be hidden in the side of the connecting seat; when the second elastic member causes the recess of the movable rod to be misaligned with the locking member, the side wall of the movable rod causes the locking member to be partially exposed in the side of the insertion part.

[0013] According to some embodiments of the present invention, the bottom of the connecting seat away from the fixed seat is provided with a clearance opening communicating with the guide channel; wherein, the movable rod is made of a magnetic material, and the movable rod can be moved toward the clearance opening by a magnetic attraction force from the clearance opening; or, the movable rod can be moved toward the clearance opening by a negative pressure from the clearance opening.

[0014] According to some embodiments of the present invention, the fixing assembly further includes a limiting member, which is at least partially elastically disposed in the connecting channel to restrict the movement of the movable rod toward the pushing member; wherein, when the locking member enters the connecting channel or after entering the connecting channel, the insertion portion pushes the limiting member to make way for the movable rod, and the movable rod can move toward the pushing member under the action of the second elastic member; or

[0015] The pushing member includes a push rod portion and elastic grippers disposed around the push rod portion. The movable end of the elastic grippers is used to restrict the movement of the movable rod toward the push rod portion. When the locking member enters the connecting channel or after entering the connecting channel, the insertion portion pushes the elastic grippers to expand outward to make way for the movable rod. The movable rod can move toward the push rod portion under the action of the second elastic member.

[0016] According to some embodiments of the present invention, if the fixing component includes a limiting member, the limiting member includes a connecting sleeve and a plurality of limiting claws, the connecting sleeve is elastically slidably disposed in the connecting channel or fixedly disposed in the connecting channel, the pushing member is provided with a push rod portion slidably disposed inside the connecting sleeve, and the limiting claws are sequentially connected to the four sides of the connecting sleeve to restrict the movement of the movable rod toward the push rod portion;

[0017] The insertion part pushes the limiting claw to expand in all directions to make way for the movable rod, and the movable rod can move toward the push rod part under the action of the second elastic member.

[0018] According to some embodiments of the present invention, the end of the movable rod is provided with a first guide slope that slides relative to the limiting member; and / or, the end of the plug portion is provided with a second guide slope that slides relative to the limiting member; and / or, the limiting member is provided with a third guide slope that slides relative to the plug portion and the movable rod.

[0019] According to some embodiments of the present invention, the pusher is further provided with an elastic arm connected to the periphery of the push rod portion, the elastic arm being located between the adjacent limiting jaws, and the end of the elastic arm being provided with a limiting arm extending circumferentially to the outside of the limiting jaws;

[0020] The outer side of the limiting gripper is provided with a limiting surface facing the insertion interface. When the push rod pushes the clearance groove of the movable rod to coincide with the locking member, the limiting arm abuts against the limiting surface.

[0021] According to some embodiments of the present invention, the inner side of the limiting gripper is provided with a reinforcing rib, and the side wall of the insertion part is provided with a strip-shaped through groove for making way for the reinforcing rib.

[0022] According to some embodiments of the present invention, the fixing assembly further includes a button and a retaining sleeve. The connecting channel forms a pressing port at the end of the fixing seat away from the locking seat. The button is disposed in the connecting channel and connected to the end of the push member away from the movable rod. The retaining sleeve is connected to the pressing port to restrict the button from sliding away from the connecting channel. The button has a pressing portion extending to the outside of the retaining sleeve. The first elastic member axially abuts against the connecting sleeve and the button.

[0023] Secondly, this application also discloses a display device, comprising:

[0024] Box frame and display module;

[0025] In the aforementioned locking mechanism, the fixing base is connected to the frame, and the locking base is connected to the bottom shell of the display module.

[0026] As can be seen from the above technical solutions, the embodiments of this application have the following advantages: When the display module is installed on the frame, the plug-in part is inserted into the connecting channel through the plug interface, and the exposed part of the locking member is engaged with the inner side of the connecting channel, thereby assembling the display module on the frame. When it is necessary to disassemble the display module, the force of the first elastic member is overcome, and the pushing member moves towards the plug interface under the action of external force. The pushing member acts directly or indirectly on the locking member, thereby causing the exposed part of the locking member to retract, thereby releasing the locking member from the connecting seat, and thus releasing the axial restriction between the locking seat and the fixed seat. At this time, the locking seat can be easily separated from the connecting seat, thereby making it easy to disassemble the display module from the frame, and making the maintenance of the display module more convenient.

[0047] The present invention will now be described in further detail with reference to the accompanying drawings.

[0048] Please see Figures 1 to 4 This invention provides a locking mechanism applied to a display device, and the description is based on an example of its application to a display device, but is not limited to display devices. The locking mechanism includes a locking component 100 and a fixing component 200. The fixing component 200 is fixed to the frame 400 of the display device, and the locking component 100 is connected to the bottom shell 320 of the display module 300 of the display device. The locking component 100 can be connected to the fixing component 200, thereby assembling the display module 300 onto the frame 400.

[0049] Specifically, the locking assembly 100 includes a locking seat 110 and a locking member 130. The locking seat 110 is provided with a plug portion 112, and one or more locking members 130 are provided. Each locking member 130 is movably disposed on the periphery of the plug portion 112 and can be at least partially exposed on the outside of the plug portion 112.

[0050] The fixing assembly 200 includes a fixing base 210, a pushing member 220, and a first elastic member 230. The fixing base 210 is provided with a connecting channel 211 along its axial direction. The connecting channel 211 forms an insertion interface 213 at one end of the fixing base 210 near the locking base 110. The insertion part 112 is inserted into the connecting channel 211 through the insertion interface 213. The locking member 130 is engaged with the inner side of the connecting channel 211. For example, the connecting channel 211 is provided with an annular protrusion 212 at the position of the insertion interface 213, and the locking member 130 is engaged with the inner side of the annular protrusion 212. The pusher 220 is slidably disposed in the guide channel 1121 so as to act on the locking member 130. The pusher 220 can be pushed so that the locking member 130 can retract to the side of the insertion part 112 to release the axial restriction between the insertion part 112 and the fixed seat 210. The first elastic member 230 is disposed in the fixed seat 210 and is used to act on the pusher 220 in a direction away from the insertion interface 213 so as to reset the pusher 220.

[0051] The latch base 110 and the bottom shell 320 of the display module 300 can be connected by assembly, such as by screws. The latch base 110 and the bottom shell 320 of the display module 300 can also be connected as an integral unit, such as by integral molding or by welding. The mounting base 210 and the frame 400 can be connected by assembly, such as by screws. The mounting base 210 and the frame 400 can also be connected as an integral unit, such as by integral molding or by welding.

[0052] In practical applications, when the display module 300 is installed on the frame 400, the plug-in part 112 is inserted into the connecting channel 211 through the plug-in interface 213. The exposed part of the locking member 130 is engaged with the inner side of the connecting channel 211, thereby assembling the display module 300 onto the frame 400. When it is necessary to disassemble the display module 300, the pushing member 220 moves towards the plug-in interface 213 under the action of external force, overcoming the force of the first elastic member 230. The pushing member 220 acts directly or indirectly on the locking member 130, thereby causing the exposed part of the locking member 130 to retract, thereby releasing the locking member 130 from the connecting seat 110, and thus releasing the axial restriction between the locking seat 110 and the fixing seat 210. At this time, the locking seat 110 can be easily separated from the connecting seat 110, thereby allowing the display module 300 to be easily disassembled from the frame 400 without the need for tools, making the maintenance of the display module 300 more convenient.

[0053] In one specific embodiment, reference is made to... Figures 5 to 7The locking assembly 100 also includes a movable rod 120 and a second elastic member 140. The insertion portion 112 has a guide channel 1121 along its axial direction. The insertion end of the insertion portion 112 has an extension port 1123 communicating with the guide channel 1121. The movable rod 120 is slidably disposed in the guide channel 1121, and one end of the movable rod 120 extends into the connecting channel 211 through the extension port 1123 to abut against the pusher 220. The side of the insertion portion 112 has a guide hole 1122, and the locking member 130 is a ball bearing disposed within the guide hole 1122. Simultaneously, the side of the movable rod 120 has an annular clearance groove 121, which allows the locking member 130 to move into the clearance groove 121, thus concealing it within the side of the locking seat 110. The second elastic member 140 is disposed on the locking seat 110 and acts on the movable rod 120 in the direction toward the fixed seat 210. When the pusher 220 pushes the clearance groove 121 of the movable rod 120 to coincide with the locking member 130, the locking member 130 can move toward the clearance groove 121 to be hidden in the side of the connecting seat 110; when the second elastic member 140 causes the clearance groove 121 of the movable rod 120 to be misaligned with the locking member 130, the side wall of the movable rod 120 causes part of the locking member 130 to be exposed in the side of the insertion part 112.

[0054] In practical applications, the locking seat 110 is connected to the bottom shell 320 of the display module 300. Under the action of the second elastic member 140, the clearance groove 121 on the movable rod 120 is offset from the guide hole 1122. That is, the outer peripheral wall of the movable rod 120 abuts against the side of the locking member 130 near the guide channel 1121. Therefore, under the restriction of the movable rod 120, part of the locking member 130 is exposed on the outside of the plug-in portion 112, thereby being securely engaged with the inner side of the connecting channel 211, so that the display module 300 is securely assembled on the frame 400. If it is necessary to remove the display module 300 from the frame 400, the pusher 220 pushes the movable rod 120 to slide into the guide channel 1121. The clearance groove 121 on the side wall of the movable rod 120 coincides with the guide hole 1122, and the locking member 130 can move towards the clearance groove 121. Thus, the movable rod 120 releases the restriction on the locking member 130, and the locking member 130 can move towards the clearance groove 121. The locking member 130 is hidden in the side of the plug-in part 112, thereby releasing the axial restriction between the latch seat 110 and the fixed seat 210. The latch seat 110 and the fixed seat 210 can be separated, so that the display module 300 can be easily removed from the frame 400.

[0055] In some embodiments, refer to Figures 5 to 7Along the axial direction of the movable rod 120, the clearance groove 121 has a first groove wall 122 and a second groove wall 123 with opposite sides. The first groove wall 122 and the second groove wall 123 are inclined outwards, that is, the first groove wall 122 and the second groove wall 123 are inclined outwards, and the first groove wall 122 is located on the side of the second groove wall 123 that is closer to the display module 300. Understandably, the first groove wall 122 is set as an outwardly expanding inclined surface. During the sliding process of the movable rod 120 along the guide channel 1121, the movable rod 120 can smoothly act outward on the locking member 130 using the first groove wall 122, thereby pushing the locking member 130 to move outward along the guide hole 1122. Thus, the movable rod 120 can smoothly slide along the guide channel 1121 and engage the locking member 130 with the fixed seat 210. At the same time, when it is necessary to pull out the movable rod 120, the movable rod 120 can smoothly act outward on the locking member 130 using the second groove wall 123, thereby pushing the locking member 130 to move outward along the guide hole 1122. Thus, the movable rod 120 can be smoothly pulled out from the guide channel 1121, thereby facilitating the disassembly of the locking buckle.

[0056] In some embodiments, refer to Figures 5 to 7 The locking base 110 also has a connecting bottom 111 connected to the insertion part 112. The connecting bottom 111 is used for assembly or integrated connection with the bottom shell 320 of the display module 300. The inner side of the connecting bottom 111 has a mounting cavity 1111. The end of the guide channel 1121 away from the extension port 1123 is connected to the mounting cavity 1111, and the movable rod 120 extends into the mounting cavity 1111. The bottom of the connecting bottom 111 away from the insertion part 112 has a clearance opening 1112. More precisely, the clearance opening 1112 is located on the side of the connecting bottom 111 close to the bottom shell 320 of the display module 300. The second elastic element 140 can be a spring and is disposed in the mounting cavity 1111. One end of the second elastic element 140 abuts against the bottom shell 320 of the display module 300, and the other end abuts against the end of the movable rod 120 near the display module 300. Thus, the second elastic element 140 acts on the movable rod 120 in the direction of the insertion part 112. With this arrangement, the movable rod 120 and the second elastic element 140 can be conveniently installed on the inside of the latch seat 110 through the mounting cavity 1111.

[0057] In some embodiments, refer to Figures 5 to 7The movable rod 120 is made of a magnetic material, such as a metal material like iron or stainless steel. The movable rod 120 can be moved towards the clearance opening 1112 by the magnetic force from the clearance opening 1112. Specifically, the clearance opening 1112 faces the display module 300, and the outer magnetic member is placed on the front of the display module 300, positioned corresponding to the clearance opening 1112. Then, the magnetic member generates a magnetic force towards the display module 300 through the clearance opening 1112. The movable rod 120 overcomes the force of the second elastic member 140 and moves towards the display module 300. The clearance groove 121 of the movable rod 120 moves to the position of the locking member 130, which can then move towards the clearance groove 121, thereby releasing the axial restriction between the locking seat 110 and the fixing seat 210, thus facilitating the disassembly of the display module 300.

[0058] In some embodiments, refer to Figures 5 to 7 The movable rod 120 can be moved towards the clearance opening 1112 by negative pressure from the clearance opening 1112. Specifically, the clearance opening 1112 is positioned facing the display module 300, and the suction cup of the outer negative pressure source 500 is placed on the front of the display module 300 and located at the position corresponding to the clearance opening 1112; at the same time, the display module 300 is also provided with a suction hole 310 (see reference). Figure 8 The suction hole 310 is located between the suction cup of the negative pressure source 500 and the clearance opening 1112. Then, the negative pressure source 500 draws out the air from the mounting cavity 1111 through the suction hole 310. At this time, the movable rod 120 moves towards the display module 300 under the action of atmospheric pressure, overcoming the force of the second elastic element 140. The clearance groove 121 of the movable rod 120 moves to the position of the locking element 130. The locking element 130 can move towards the clearance groove 121, thereby releasing the axial restriction between the locking seat 110 and the fixed seat 210, thus facilitating the disassembly of the display module 300.

[0059] Furthermore, the locking seat 110 also includes a movable adhesive 150 disposed in the mounting cavity 1111, and a movable rod 120 passing through and connected to the movable adhesive 150. This arrangement ensures that the section of the movable rod 120 near the clearance opening 1112 is within a sealed space. The negative pressure source 500 can fully remove the gas from the mounting cavity 1111 through the suction hole 310, placing the mounting cavity 1111 under a large negative pressure. Under atmospheric pressure, the movable adhesive 150 can deform towards the clearance opening 1112, causing the movable rod 120 to move towards the clearance opening 1112. This allows the clearance groove 121 of the movable rod 120 to move to the position of the locking member 130, thereby releasing the axial restriction between the locking seat 110 and the fixed seat 210.

[0060] Furthermore, the movable adhesive 150 is a negative pressure cover disposed inside the mounting cavity 1111. The negative pressure cover has a negative pressure port 1521 located at the relief opening 1112, and the movable rod 120 is partially located inside the negative pressure cover. Specifically, the negative pressure cover includes a cover portion 151 and a surrounding portion 152. The surrounding portion 152 is connected to the periphery of the cover portion 151. The cover portion 151 is corrugated and is located approximately at the bottom of the mounting cavity 1111 near the guide channel 1121. The movable rod 120 passes through and is connected to the center of the cover portion 151. The outer peripheral surface of the surrounding portion 152 is fitted against the inner wall of the mounting cavity 1111, and a negative pressure port 1521 is formed at the relief opening 1112. One section of the movable rod 120 is located inside the negative pressure cover. Thus, the movable rod 120 is sealed to the mounting cavity 1111 through the negative pressure cover. When the connecting latch is assembled on the display module 300, the edge of the surrounding part 152 away from the cover part 151 is sealed to the bottom shell 320 of the display module 300, and the suction hole 310 on the display module 300 is connected to the inside of the negative pressure cover through the negative pressure port 1521.

[0061] In practical applications, the negative pressure source 500 can fully extract the gas from the negative pressure cover through the suction hole 310. Under atmospheric pressure, the cover part 151 deforms towards the display module 300 through the corrugated part, and the movable rod 120 moves towards the display module 300. The clearance groove 121 of the movable rod 120 moves to the position of the locking member 130, and the locking member 130 can move towards the clearance groove 121, thereby releasing the axial restriction between the locking seat 110 and the fixed seat 210.

[0062] In some embodiments, refer to Figure 4 and Figure 9 The fixing component 200 also includes a limiting member 240, which is at least partially elastically disposed in the connecting channel 211 and located near the insertion interface 213. The pushing member 220 is provided with a pushing end 2211 for pushing the movable rod 120, and the limiting member 240 is used to restrict the movement of the movable rod 120 toward the pushing end 2211 of the pushing member 220. Specifically, when the locking member 130 enters or after entering the connecting channel 211, the insertion portion 112 pushes the limiting member 240 to make way for the movable rod 120, and the movable rod 120 can move toward the pushing end 2211 of the pushing member 220 under the action of the second elastic member 140.

[0063] Specifically, during the assembly process of the display module 300 and the frame 400, in the first insertion stage, refer to Figure 4Under the action of the second elastic member 140, the movable rod 120 is extended from the extension port 1123, and the clearance groove 121 of the movable rod 120 is misaligned with the locking member 130, with part of the locking member 130 exposed outside the insertion part 112. Therefore, when the insertion part 112 of the latch seat 110 is inserted into the connecting channel 211, the end of the movable rod 120 preferentially abuts against the limiting member 240. In the second insertion stage, the insertion part 112 continues to move toward the connecting channel 211, and the movable rod 120, under the restriction of the limiting member 240, overcomes the force of the second elastic member 140 and slides toward the guide channel 1121 until the movable rod 120 is substantially hidden in the guide channel 1121. At this time, the clearance groove 121 of the movable lever 120 moves to the position of the locking member 130, and the locking member 130 can move toward the clearance groove 121 to hide in the side of the latch seat 110, thereby preparing for sliding into the connecting channel 211 (see reference). Figure 10 In the third insertion stage, the insertion part 112 continues to move toward the connection channel 211, with its end abutting against the limiting member 240. As the insertion part 112 continues to move toward the connection channel 211, it gradually pushes open the limiting member 240, thereby making way for the movable rod 120. Before the insertion part 112 fully pushes open the limiting member 240, the locking member 130 partially or completely slides into the connection channel 211. Therefore, although the limiting member 240 has made way for the movable rod 120, the locking member 130, because it is partially located in the limiting groove, restricts the movement of the movable rod 120 toward the pushing end 2211 of the pushing member 220. In the fourth insertion stage, after the insertion part 112 fully pushes open the limiting member 240, the insertion part 112 continues to move towards the connection channel 211. The locking member 130 is in a retracted state and moves inward along the connection channel 211 until the bottom of the connection 111 abuts against the end of the fixing seat 210, and the limiting member 240 just moves to the inner side of the annular protrusion 212 (see reference). Figure 11 At this time, under the action of the second elastic member 140, the movable rod 120 moves toward the pushing end 2211 of the pushing member 220. The movable rod 120 pushes the locking member 130 out of the guide hole 1122 through the first groove wall 122 and locks it inside the annular protrusion 212. Because the second elastic member 140 keeps the movable rod 120 in the extended state from the extension port 1123, the side wall of the movable rod 120 restricts the movement of the locking member 130 toward the guide channel 1121, thereby making the locking member 130 firmly locked inside the annular protrusion 212, and thus making the display module 300 firmly assembled on the frame 400.

[0064] As can be seen from the above, a limiting member 240 is provided in the connecting channel 211. During the insertion of the plug part 112 into the connecting channel 211, the limiting member 240 causes the movable rod 120 to retract into the guide channel 1121, thereby causing the relief groove 121 to coincide with the locking member 130, and thus allowing the locking member 130 to be hidden in the side of the plug part 112. With this configuration, the locking member 130 is less likely to interfere with the insertion of the plug part 112 into the connecting channel 211, and the locking member 130 can also move into the connecting channel 211 along with the plug part 112, thereby engaging with the side of the connecting channel 211. At the same time, after the locking member 130 moves into place, the second elastic member 140 can automatically extend the movable rod 120 from the extension port 1123, thereby keeping part of the locking member 130 exposed on the outside of the plug part 112, thus securely engaging with the side of the connecting channel 211.

[0065] In one possible embodiment, reference is made to... Figure 4 , Figure 9 and Figure 12 The limiting member 240 includes a connecting sleeve 241 and multiple limiting claws 242. The connecting sleeve 241 is elastically slidably disposed in the connecting channel 211 in a direction away from the insertion interface 213 by means of a first elastic member 230 or other elastic members. In other words, the first elastic member 230 provides an elastic force to the connecting sleeve 241 toward the insertion interface 213. Alternatively, the connecting sleeve 241 may be fixedly disposed on the inner wall of the connecting channel 211. The pushing member 220 has a push rod portion 221 slidably disposed inside the connecting sleeve 241, and the end of the push rod portion 221 near the insertion interface 213 is the pushing end 2211. Limiting claws 242 are sequentially connected around the connecting sleeve 241. Each limiting claw 242 extends toward the insertion interface 213. A limiting protrusion 2421 is provided on the inner side of the end of the limiting claw 242 near the insertion interface 213. The limiting protrusion 2421 is used to restrict the movement of the movable rod 120 toward the pushing end 2211 of the push rod part 221. The insertion part 112 pushes the limiting protrusion 2421 of the limiting claw 242 to expand outward to make way for the movable rod 120. The movable rod 120 can move toward the pushing end 2211 of the push rod part 221 under the action of the second elastic member 140.

[0066] In practical application, during the insertion of the plug-in portion 112 into the connecting channel 211, the limiting protrusion 2421 of the limiting claw 242 abuts against the movable rod 120, causing the movable rod 120 to retract into the guide channel 1121. This allows the clearance groove 121 to coincide with the locking member 130, thereby allowing the locking member 130 to be hidden within the side of the plug-in portion 112. As the plug-in portion 112 continues to move towards the connecting channel 211, the movable rod 120 overcomes the force of the first elastic member 230 and pushes the connecting sleeve 241 away from the plug-in interface 213 through the limiting protrusion 2421 of the limiting claw 242, thus allowing the locking member 130 to remain in a retracted state and slide into the connecting channel 211. Of course, in other embodiments, the connecting sleeve 241 may not need to be slidable, and the locking member 130 may remain in a retracted state and slide into the connecting channel 211, which will not be described in detail here. When the first elastic element 230 is compressed to a certain extent, its elastic force is greater than that of the second elastic element 140. At this time, the end of the insertion part 112 acts on the limiting protrusion 2421 of the limiting claw 242. Under the action of the insertion part 112, each limiting claw 242 elastically deforms outward, causing the limiting protrusion 2421 of the limiting claw 242 to unfold in all directions, releasing the resistance force on the movable rod 120. Therefore, after the locking member 130 moves into position, the movable rod 120 moves towards the push rod part 221 under the action of the second elastic element 140, so that the locking member 130 is exposed, allowing the display module 300 to be securely mounted on the frame 400. When the insertion part 112 separates from the connecting channel 211, each limiting claw 242 returns to its initial position, preparing to restrict the movable rod 120 next time.

[0067] It is understandable that the limiting member 240 adopts the above-mentioned structural form. The overall structure of the limiting member 240 is relatively simple and easy to assemble. The cooperation of multiple limiting claws 242 can effectively limit the movable rod 120 and prevent the limiting claws 242 from being opened by the action of the second elastic member 140.

[0068] In other possible embodiments, multiple limiting members 240 may be provided, which are radially slidably disposed around the fixed base 210 and elastically disposed with respect to the fixed base 210. In application, the insertion part 112 overcomes the elastic force of each limiting member 240 and pushes each limiting member 240 to slide in all directions, thereby making way for the movable rod 120.

[0069] In a different embodiment than the aforementioned limiting member 240, the pushing member 220 includes a push rod portion 221 and elastic grippers (not shown in the figure) disposed around the push rod portion 221. The push rod portion 221 is elastically slidably disposed in the connecting channel 211, and the end of the push rod portion 221 near the insertion interface 213 is the pushing end 2211. The elastic grippers are sequentially connected around the push rod portion 221, and each elastic gripper extends toward the insertion interface 213. An elastic protrusion is provided on the inner side of the end of the elastic gripper near the insertion interface 213. The elastic protrusion is used to restrict the movement of the movable rod 120 toward the pushing end 2211 of the push rod portion 221. The insertion portion 112 pushes the elastic protrusion of the elastic gripper to expand outward to make way for the movable rod 120, and the movable rod 120 can move toward the pushing end 2211 of the push rod portion 221 under the action of the second elastic member 140.

[0070] In practical application, during the insertion of the plug-in part 112 into the connecting channel 211, the elastic protrusions of the elastic claws abut against the movable rod 120, causing the movable rod 120 to retract into the guide channel 1121. This allows the clearance groove 121 to coincide with the locking member 130, thereby allowing the locking member 130 to be hidden within the side of the plug-in part 112. As the plug-in part 112 continues to move into the connecting channel 211, the end of the plug-in part 112 acts on the elastic protrusions of the elastic claws. Under the action of the plug-in part 112, each elastic claw elastically deforms outward, causing the elastic protrusions of the elastic claws to expand outward, releasing the holding force on the movable rod 120. Therefore, after the locking member 130 has moved into place, the movable rod 120 moves towards the push rod part 221 under the action of the second elastic member 140, exposing the locking member 130 so that the display module 300 is securely mounted on the frame 400.

[0071] In some embodiments, refer to Figure 4 and Figure 9 The end of the movable rod 120 is provided with a first guide slope 124 that slides relative to the limiting member 240; and / or, the end of the plug-in part 112 is provided with a second guide slope 1124 that slides relative to the limiting member 240; and / or, the limiting member 240 is provided with a third guide slope 2422 that slides relative to the plug-in part 112 and the movable rod 120.

[0072] For ease of explanation, this application uses the simultaneous provision of a first guide slope 124, a second guide slope 1124, and a third guide slope 2422 as an example. In the second insertion stage described above, the first guide slope 124 and the third guide slope 2422 are in contact. As the insertion part 112 moves toward the connecting channel 211, the movable rod 120 utilizes the relative sliding of the first guide slope 124 and the third guide slope 2422 to push the limiting gripper 242 out at a small angle, thereby allowing the insertion end of the insertion part 112 to smoothly insert between the limiting parts, further pushing the limiting gripper 242 out. In the third insertion stage described above, the insertion part 112 utilizes the relative sliding of the second guide slope 1124 and the third guide slope 2422 to further push the limiting gripper 242 out, making way for the movable rod 120. As can be seen from the above, the solution of this application can be implemented relatively smoothly by setting the first guide slope 124, the second guide slope 1124 and the third guide slope 2422.

[0073] In order to keep the pusher 220 in a pressed state so that the movable rod 120 remains retracted within the guide channel 1121, in some embodiments, refer to Figure 9 , Figure 12 and Figure 13 The pusher 220 is also provided with multiple elastic arms 222, which are sequentially connected around the push rod portion 221 and extend toward the insertion interface 213. Each elastic arm 222 is located between the gaps of adjacent limiting claws 242. The end of the elastic arm 222 is provided with a limiting arm 2221 extending circumferentially to the outside of the limiting claw 242. The outer side of the limiting claw 242 is provided with a limiting surface 2423 facing the insertion interface 213. When the push rod portion 221 pushes the clearance groove 121 of the movable rod 120 to coincide with the locking member 130, the limiting arm 2221 abuts against the limiting surface 2423.

[0074] Specifically, when it is necessary to remove the display module 300 from the frame 400, the push rod 221 moves toward the movable rod 120 under the action of external force, and pushes the movable rod 120 to slide into the guide channel 1121. At this time, the clearance groove 121 of the movable rod 120 coincides with the locking member 130, and the locking member 130 can move toward the clearance groove 121 to hide in the side of the plug-in part 112, thereby releasing the axial restriction between the fixing seat 210 and the locking seat 110, and thus facilitating the removal of the display module 300 from the frame 400. When the push rod 221 pushes the movable rod 120 to the guide channel 1121, the elastic arm 222 elastically deforms outward, and the limiting arm 2221 slides along the outside of the limiting gripper 242 to the position of the limiting surface 2423, and moves to the limiting surface 2423 under the restoring force of the elastic arm 222, that is, the limiting arm 2221 is hung on the limiting surface 2423. At this time, the limiting surface 2423 restricts the pusher 220 to reset under the action of the first elastic member 230 through the limiting arm 2221, thereby keeping the push rod 221 against the movable rod 120, and thus keeping the movable rod 120 in the guide channel 1121. Therefore, the locking member 130 remains unlocked from the fixed seat 210, and the operator does not need to keep pressing the pusher 220, which further facilitates the disassembly of the display module 300. Especially when a single display module 300 is connected to the frame 400 through multiple locking mechanisms, the operator can unlock each locking mechanism in sequence without keeping it pressed, making the operation more convenient. When the display module 300 is separated from the frame 400, the limiting claw 242 retracts inward, the limiting surface 2423 releases the restriction on the limiting arm 2221, and the pusher 220 resets to its initial position under the action of the first elastic member 230.

[0075] To increase the strength of the limiting gripper 242, in some embodiments, refer to Figure 9 , Figure 12 and Figure 13 The limiting gripper 242 has a raised reinforcing rib 243 on the inner side of the limiting protrusion 2421, and the reinforcing rib 243 extends to the inner side of the extension arm of the limiting gripper 242. Thus, the reinforcing rib 243 increases the strength of the end of the limiting gripper 242, effectively restricting the movable rod 120. Meanwhile, the side wall of the insertion part 112 has a strip-shaped through groove 1125 along its length (see reference). Figure 3 The strip-shaped through groove 1125 extends through the inner side of the insertion portion 112 and the insertion end of the insertion portion 112. When the insertion portion 112 is inserted between the limiting protrusions 2421 of the elastic gripper, the reinforcing rib 243 is embedded in the strip-shaped through groove 1125. In other words, the strip-shaped through groove 1125 makes way for the reinforcing rib 243, thus enabling the present application to be implemented.

[0076] In some embodiments, refer to Figure 4 and Figure 9The fixing assembly 200 also includes a button 250 and a retaining sleeve 260. A pressing port 214 is formed at the end of the fixing base 210 away from the locking seat 110 in the connecting channel 211. The retaining sleeve 260 is threadedly connected to the connecting channel 211 through the pressing port 214. The button 250 is disposed within the connecting channel 211, and the retaining sleeve 260 is used to prevent the button 250 from sliding out of the connecting channel 211. The inner end of the button 250 is fixedly connected to the push rod portion 221 of the pusher 220, and the outer end of the button 250 is provided with a pressing portion 251 extending to the outside of the retaining sleeve 260, allowing the operator to press the button 250 inward through the pressing portion 251. Meanwhile, the first elastic element 230 can be a spring. The first elastic element 230 is sleeved on the outside of the push rod portion 221 and abuts against the inside of the button 250 and the connecting sleeve 241 of the push member 220. That is, the end of the connecting sleeve 241 away from the first elastic element 230 abuts against the side wall of the fixed base 210. Thus, the first elastic element 230 causes the connecting sleeve 241 to slide elastically in the connecting channel 211 away from the insertion interface 213.

[0077] In practical application, when the operator presses the pressing part 251 of the button 250, the button 250 overcomes the elastic force of the first elastic member 230 and drives the push rod part 221 of the push member 220 to move towards the movable rod 120, thereby pushing the movable rod 120 to slide to the inside of the guide channel 1121, thus unlocking the locking seat 110 from the connecting seat 110. When the button 250 is stopped being pressed, the first elastic member 230 pushes the button 250 to reset backward, thereby driving the push member 220 to reset backward to its initial position.

[0078] This application also discloses a display device, as shown in the reference. Figures 1 to 4 The device includes a frame 400, a display module 300, and the aforementioned locking mechanism. The fixing seat 210 is connected to the frame 400, and the locking seat is connected to the bottom shell 320 of the display module 300. When the fixing seat 210 is connected to the locking seat 110, the display module 300 is thus assembled onto the frame 400.

[0079] The latch base 110 and the bottom shell 320 of the display module 300 can be connected by assembly, such as by screws. The latch base 110 and the bottom shell 320 of the display module 300 can also be connected as an integral unit, such as by integral molding or by welding. The mounting base 210 and the frame 400 can be connected by assembly, such as by screws. The mounting base 210 and the frame 400 can also be connected as an integral unit, such as by integral molding or by welding.

[0080] It is understandable that the display device uses the above-mentioned locking mechanism. When the display module 300 is disassembled from the frame 400, the plug part 112 is inserted into the connection channel 211 through the plug interface 213, and the exposed part of the locking member 130 is engaged with the inner side of the connection channel 211, so that the display module 300 is assembled on the frame 400. When the display module 300 needs to be disassembled, the force of the first elastic member 230 is overcome, and the pushing member 220 moves toward the insertion interface 213 under the action of external force. The pushing member 220 acts directly or indirectly on the locking member 130. As a result, the pushing member 220 causes the exposed part of the locking member 130 to retract to the side of the insertion part 112. The locking member 130 is released from the engagement with the connecting seat 110, thereby releasing the axial restriction between the locking seat 110 and the fixing seat 210. At this time, the locking seat 110 can be easily separated from the connecting seat 110, so that the display module 300 can be easily removed from the frame 400.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
