[0031] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0032] In the description of this application, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back, etc.) are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the mechanism or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0034] The existing LED display power supply boxes are usually fixed to the cabinet frame with buckles or screws, which makes it inconvenient to disassemble and assemble the power supply box.

[0035] Please see Figures 1 to 14 This embodiment provides a display device 100, which includes a housing frame 30, a display panel, a power supply box 20, and a lock 10. The lock 10 enables the power supply box 20 to be quickly fixed and disassembled from the housing frame 30.

[0036] The front side of the enclosure frame 30 is equipped with a display panel for displaying images. A power supply box 20 is located on the rear side of the enclosure frame 30. The power supply box 20 is electrically connected to the display panel to provide power or transmit data. The enclosure frame 30 can be die-cast from aluminum profiles to form a rectangular frame structure. An assembly area 31 for mounting the power supply box 20 can be provided in the middle of the rear side of the enclosure frame 30. Connecting plates 21 are provided at both ends of the power supply box 20. The connecting plates 21 are fixedly connected to the box body and extend along the length of the power supply box 20. Each connecting plate 21 has a through hole 211 for a lock 10 to pass through, allowing the power supply box 20 to be assembled into the assembly area 31 of the enclosure frame 30.

[0037] Please see Figures 2 to 7 In this embodiment, the lock 10 includes a rotating member 11 and a locking member 12.

[0038] The rotating component 11 includes a locking rod 111 and a gripping part 113. The gripping part 113 is fixedly disposed at one end of the locking rod 111, and a locking part 112 is provided on the peripheral wall of the other end of the locking rod 111 away from the gripping part 113. The locking component 12 includes a locking body 121, a first limiting part 122, and a second limiting part 123. The locking body 121 is provided with a locking hole 1214, which is used for the locking part 112 on the locking rod 111 to enter the locking body 121. The first limiting part 122 and the second limiting part 123 are disposed in the locking body 121 and are used to cooperate with the locking part 112.

[0039] When the gripping part 113 rotates the locking bar 111 in the first direction, the locking part 112 gradually abuts against the first limiting part 122, and drives the locking bar 111 to move toward the locking member 12 to lock the device to be locked. When the gripping part 113 rotates the locking bar 111 in the second direction opposite to the first direction, the locking part 112 gradually abuts against the second limiting part 123, and drives the locking bar 111 away from the locked member 12 to unlock the device to be locked.

[0040] Specifically, such as Figure 1 and Figure 2 As shown, one end of the locking lever 111 is provided with a grip portion 113, which has a knob structure for easy gripping and rotation by the user. The grip portion 113 can be fixedly connected to the locking lever 111 or detachably connected. A locking portion 112 for locking function is formed on the peripheral wall of the other end of the locking lever 111. The locking lever 111 passes through the through hole 211 on the connecting plate 21 of the power supply box 20. The locking member 12 is fixedly installed at a corresponding position on the housing frame 30. The locking member 12 includes a locking body 121 with an internal receiving cavity, and a first limiting portion 122 and a second limiting portion 123 disposed in the receiving cavity. The first limiting portion 122 and the second limiting portion 123 are configured to gradually contact the locking portion 112 on the locking lever 111 in different rotational directions, and correspondingly produce a guiding effect that pushes the locking lever 111 inward or outward.

[0041] like Figure 3 As shown, during the installation of the power box 20, the user can first align the power box 20 with the assembly area 31 on the enclosure frame 30, and then pass one end of the locking rod 111 through the through hole 211 on the connecting plate 21 and insert it into the lock hole 1214 of the locking member 12. Subsequently, the user rotates the gripping part 113 of the lock 10, causing the locking rod 111 to rotate in the first direction. As the rotation proceeds, the locking part 112 gradually slides along the first limiting part 122 in the locking member 12, thereby driving the locking rod 111 to move towards the enclosure frame 30, so that a reliable locking force is generated between the power box 20 and the enclosure frame 30, and the power box 20 is firmly installed in the enclosure frame 30.

[0042] During disassembly, the user rotates the gripping part 113 in the opposite direction, and the locking part 112 gradually contacts the second limiting part 123. Under the push of the second limiting part 123, the locking rod 111 moves outward, disengaging it from the clamping position of the housing frame 30. At this time, the power box 20 can be easily removed, achieving quick disassembly, which is especially suitable for lockable devices such as the power box 20 that require quick replacement.

[0043] Please see Figure 5 and Figure 6 In some embodiments, the locking body 121 includes a base plate 1212, a top plate 1211, and a support column 1213. The support column 1213 connects the top plate 1211 and the base plate 1212 to form a receiving cavity therebetween. A lock hole 1214 is provided on the top plate 1211 and communicates with the receiving cavity. A first limiting part 122 is provided on the top plate 1211, and a second limiting part 123 is provided on the base plate 1212. The bottom surface of the first limiting part 122 and the top surface of the second limiting part 123 are spaced apart from each other to form a channel for the locking part 112 to pass through.

[0044] Specifically, four support columns 1213 are provided, arranged circumferentially along the locking body 121, to fix the top plate 1211 and the bottom plate 1212 together, so that the locking body 121 forms a rectangular frame structure. A lock hole 1214 is provided on the top plate 1211, which communicates with the receiving cavity. The lock hole 1214 is approximately rectangular and matches the front projection shape of the locking part 112 on the locking rod 111, so that the end of the locking rod 111 and the locking part 112 of the rotating member 11 can enter the locking body 121.

[0045] like Figure 5 and Figure 10 As shown, the top plate 1211 has first screw holes 1215 at both ends of the lock hole 1214. The housing frame 30 has a locking component mounting area 32, which has a through hole 321 matching the lock hole 1214 and a second screw hole 322 corresponding to the first screw hole 1215. This allows the fastening screw to pass through the first screw hole 1215 and the second screw hole 322 to securely fix the locking body 121 to the housing frame 30.

[0046] like Figure 6 As shown, to avoid interference between the fastening screws and the base plate 1212, the base plate 1212 is provided with a clearance notch 1216 corresponding to the screw hole of the top plate 1211. The clearance notch 1216 is semi-circular, which provides leeway for the fastening screw to pass through the base plate 1212 smoothly, so as to facilitate the fixing of the locking body 121 to the box frame 30.

[0047] Please continue reading. Figure 2 and Figure 3In this embodiment, a first limiting part 122 is provided on the inner side of the top plate 1211. The first limiting part 122 protrudes toward the bottom plate 1212, and the thickness of the protrusion of the first limiting part 122 gradually increases along the first direction. When the locking part 112 rotates along the first direction, the bottom surface of the first limiting part 122 can press against the locking part 112, so that the locking rod 111 moves toward the locking member 12. A second limiting part 123 is provided on the inner side of the bottom plate 1212. The second limiting part 123 protrudes toward the top plate 1211, and the thickness of the protrusion of the second limiting part 123 gradually increases along the second direction. When the locking part 112 rotates along the second direction, the top surface of the second limiting part 123 can gradually press against the locking part 112, so that the locking rod 111 moves away from the locking member 12.

[0048] Specifically, such as Figure 3 As shown, the bottom surface of the first limiting part 122 gradually slopes downward along the first rotation direction of the locking rod 111 to form an inclined structure. The top surface of the second limiting part 123 gradually slopes upward along the second rotation direction to form a relative inclined surface. That is, a parallel and spaced limiting channel is formed between the bottom surface of the first limiting part 122 and the top surface of the second limiting part 123, which is used for the passage of the locking part 112 at the end of the locking rod 111.

[0049] When the locking lever 111 drives the locking part 112 to rotate around the first direction, the locking part 112 gradually presses against the bottom slope of the first limiting part 122. That is, the locking part 112 gradually slides along the bottom slope of the first limiting part 122 towards a thicker position. The bottom slope of the first limiting part 122 applies a downward pressing force to the locking part 112, thereby gradually pressing the locking lever 111 towards the locking member 12 during rotation. This allows the power box 20 and other locking devices to be pushed towards the housing frame 30, achieving a tightening effect as the rotation progresses.

[0050] When the locking lever 111 drives the locking part 112 to rotate in the second direction (i.e., opposite to the first direction), the outer edge of the locking part 112 will press against the top inclined surface of the second limiting part 123. During continuous rotation, it will move along the top inclined surface of the second limiting part 123 to a higher position, causing the locking lever 111 to move outward relative to the locking member 12. Therefore, during the unlocking operation, the locking lever 111 can be actively pushed out, allowing the locking part 112 to smoothly disengage from the receiving cavity of the locking member 12, thus achieving a reliable unlocking function.

[0051] Through the wedge-shaped thickness variation structure of the first limiting part 122 and the second limiting part 123, the lock 10 can automatically generate the required axial displacement auxiliary force during locking and unlocking, realizing the two-way self-service function of "automatic pressing upon rotation" and "automatic disengagement upon reverse rotation", effectively improving the ease of operation of the lock 10.

[0052] Please see Figure 6In some embodiments, two first limiting portions 122 are provided, respectively disposed on both sides of the lock hole 1214 of the top plate 1211, and the two first limiting portions 122 are centrally symmetrically arranged around the lock hole 1214. That is, each first limiting portion 122 has a gradually increasing protrusion thickness along a first direction, so that its bottom slope together forms a limiting guide area with a double slope structure around the lock hole 1214. Correspondingly, the second limiting portions 123 are also disposed in pairs on the bottom plate 1212, with the two second limiting portions 123 respectively arranged at positions corresponding to the two first limiting portions 122 of the top plate 1211, and also having a gradually thickening wedge-shaped structure.

[0053] Through the cooperation of the two sets of limiting structures, the locking rod 111 can achieve stable and reliable axial displacement under the action of guiding force and extrusion force on both sides during locking and unlocking.

[0054] Please see Figure 7 In some embodiments, the locking part 112 includes a first lock head 1121 and a second lock head 1122. The first lock head 1121 and the second lock head 1122 protrude from opposite sides of the peripheral wall of the locking rod 111, are located at the same height of the locking rod 111, and are centrally symmetrically arranged with respect to the axis of the locking rod 111.

[0055] Specifically, in order to enable the locking part 112 to cooperate with the two sets of limiting part structures, the locking part 112 includes a first lock head 1121 and a second lock head 1122 that are centrally symmetrical, so that the locking part 112 is always subjected to force on both sides during locking and unlocking, thereby achieving a stable guiding effect.

[0056] When the locking lever 111 rotates in the first direction to enter the locking process, the first locking head 1121 and the second locking head 1122 simultaneously contact the two first limiting parts 122 located at their corresponding positions. As the rotation angle increases, each locking head slides along the thicker part of its corresponding first limiting part 122. At this time, the compressive force exerted by the two first limiting parts 122 on the two locking heads is symmetrical.

[0057] During the unlocking process, as the locking lever 111 rotates in the second direction, the first locking head 1121 and the second locking head 1122 respectively come into contact with the top surfaces of the two second limiting parts 123. As the rotation angle increases, the two locking heads simultaneously move up along the inclined top surface of the second limiting parts 123, ensuring that the thrust exerted by the two second limiting parts 123 on the locking heads remains symmetrical. This allows the locking lever 111 to be smoothly pushed out of the receiving cavity axially.

[0058] Through the coordinated action of the double locking heads and double limiting parts, the locking rod 111 receives a uniform downward or upward axial thrust, allowing it to move stably toward the locking member 12 without deflection, jamming, or structural wear caused by unilateral force. Simultaneously, the double-sided cooperation improves the synchronicity of the locking action, enabling the locking part 112 to accurately enter the positioning area of ​​the receiving cavity, making the locking process smoother and more reliable.

[0059] Please see Figure 7 and combined Figure 3 In some embodiments, both the first lock head 1121 and the second lock head 1122 are provided with opposing first abutment surfaces 1123 and second abutment surfaces 1124. The first abutment surface 1123 faces the grip portion 113 and gradually moves away from the grip portion 113 along a first direction. The second abutment surface is opposite to the grip portion 113 and gradually moves closer to the grip portion 113 along a second direction.

[0060] Specifically, the first lock head 1121 and the second lock head 1122 have an arc-shaped structure. The side facing the grip portion 113 forms a first abutment surface 1123, while the side away from the grip portion 113 forms a second abutment surface 1124. The two abutment surfaces transition naturally on the arc surface of the lock head without any sharp edges, enabling smooth contact during rotation.

[0061] like Figure 3 As shown, the first contact surface 1123 and the first contact surface 1123 are parallel guide slopes. Their inclination direction is the same as that of the bottom surface of the first limiting part 122 and the top surface of the second limiting part 123, but the inclination angle is slightly greater than that of the first limiting part 122 and the second limiting part 123, so as to prevent the locking part 112 from interfering with the limiting part and getting stuck.

[0062] During the locking process, the user rotates the grip 113 in the first direction, causing the first contact surface 1123 to abut against the bottom surface of the first limiting part 122, thus lowering the locking rod 111. During the unlocking process, the user rotates the grip 113 in the second direction, causing the second contact surface 1124 to abut against the top surface of the second limiting part 123, thus raising the locking rod 111.

[0063] Please see Figure 6 In some embodiments, the locking bar 111 includes a bar segment 1111, an abutment platform 1112, and a connecting segment 1113. The connecting segment 1113 is used to be fixedly connected to the gripping part 113, and the abutment platform 1112 is disposed between the bar segment 1111 and the connecting segment 1113 to press against the device to be locked.

[0064] Specifically, the rod segment 1111 has a circular cross-section, used to pass through the through hole 211 on the connecting plate 21 of the power box 20 and cooperate with the locking member 12. The connecting segment 1113 is located at the other end of the locking rod 111. The cross-section of the connecting segment 1113 can be non-circular, such as elliptical, polygonal, or irregularly shaped with flat guide edges, so that after the connecting segment 1113 is inserted into the grip part 113, even if it is not completely fixed, it cannot rotate within the mounting hole 213, thereby preventing relative rotation between the locking rod 111 and the grip part 113. The grip part 113 is provided with a non-circular mounting groove corresponding to the shape of the connecting segment 1113. After the connecting segment 1113 is inserted, it is locked by screws 114, so that the grip part 113 and the locking rod 111 form a stable and non-rotatable integral structure.

[0065] The abutment platform 1112 is located between the rod section 1111 and the connecting section 1113, and is a boss structure with an outer diameter significantly larger than that of the rod section 1111. When the user rotates the locking rod 111 in the first direction to lock it, the locking part 112 gradually comes into contact with the first limiting part 122 and generates an axial driving force, causing the locking rod 111 to move as a whole toward the locking member 12. As the locking rod 111 moves, the abutment platform 1112 located between the rod section 1111 and the connecting section 1113 presses against the outer surface of the connecting plate 21 of the power box 20. The abutment platform 1112 converts the axial movement of the locking rod 111 into a pressing force on the power box 20, so that the connecting plate 21 of the power box 20 is tightly attached to the corresponding installation area of ​​the enclosure frame 30, and the power box 20 is securely locked onto the enclosure frame 30.

[0066] During unlocking, the grip 113 rotates the locking lever 111 in the second direction, causing the locking part 112 to slide along the top surface of the second limiting part 123 and generate a reverse axial thrust, thereby gradually releasing the pressing force of the abutment platform 1112 on the power box 20 connecting plate 21. When the locking part 112 is completely separated from the second limiting part 123, the locking lever 111 returns to its initial position, at which point the abutment platform 1112 no longer applies pressure, and the power box 20 can be removed.

[0067] Please see Figures 11 to 14 In some embodiments, the connecting plate 21 of the power supply box 20 is provided with a guide groove 212, which is arranged in an arc shape. The gripping part 113 of the rotating member 11 is provided with a guide post 1131 that matches the guide groove 212. The guide post 1131 can move along the extension direction of the guide groove 212 to guide the rotation of the gripping part 113.

[0068] Specifically, the connecting plate 21 of the power supply box 20 is provided with an arc-shaped guide groove 212. This guide groove 212 extends along the rotation direction of the grip 113 and follows an arc-shaped trajectory to limit the maximum rotatable angle of the grip 113. The depth of the guide groove 212 can be designed according to the size of the guide post 1131 of the grip 113, so that the guide post 1131 can slide smoothly in the groove without dislodging. The guide post 1131 on the grip 113 is usually a cylindrical protrusion with a diameter slightly smaller than the width of the guide groove 212 to ensure that the guide post 1131 can slide smoothly along the guide groove 212 during rotation.

[0069] When the user operates the grip 113 to lock or unlock, the guide post 1131 remains within the guide groove 212, pushing the grip 113 to rotate along a predetermined trajectory. Simultaneously, the guide post 1131, constrained by the arc-shaped wall of the guide groove 212, limits the rotation range of the grip 113, ensuring it can only move within an allowable angle range, thus preventing excessive rotation that could cause structural damage or rotational failure.

[0070] Please see Figures 11 to 14 In some embodiments, the grip portion 113 has a groove 1132 on the side facing the locking portion 112. The groove 1132 is arc-shaped, and positioning holes 1133 are provided at both ends of the groove 1132. The connecting plate 21 is provided with glass beads 22 that match the groove 1132. When the glass beads 22 slide along the groove 1132 to the positioning hole 1133, tactile feedback is generated to indicate that the grip portion 113 has rotated to the positioning position.

[0071] Specifically, the slide groove 1132 extends along the rotation direction of the locking rod 111, and its cross-section has a groove-shaped structure, including a bottom surface and limiting walls on both sides. Positioning holes 1133 are respectively provided at both ends of the slide groove 1132. The diameter of the positioning holes 1133 is slightly larger than the width of the slide groove 1132, so that the positioning holes 1133 form local concave areas at both ends of the slide groove 1132. When the glass bead 22 enters this concave area, it can produce a distinct "locking" tactile sensation, thus forming a positioning structure.

[0072] The power supply box 20 has a mounting hole 213 on its connecting plate 21, and the glass bead 22 is housed in the mounting hole 213. The glass bead 22 mainly consists of a shell, a spring, and a glass bead. The shell has an inverted conical cavity inside, and the spring is located in the cavity of the shell to push the glass bead outward, so that the glass bead always partially protrudes from the outside of the shell to contact the slide groove 1132.

[0073] During the locking or unlocking rotation, the arc-shaped groove 1132 of the grip 113 moves relative to the glass bead 22 on the connecting plate 21. Under the action of the spring force, the glass bead continuously presses against the bottom surface of the groove 1132 and slides along the path of the groove 1132. Because the glass bead is pushed by the spring, it exhibits slight damping on the surface of the groove 1132, giving the grip 113 moderate resistance when rotating, which can prevent accidental operation caused by excessive rotation. When the grip 113 rotates and the glass bead slides to the positioning hole 1133 at one end of the groove 1132, the glass bead will automatically spring into the positioning hole 1133 under the action of the spring force, producing a distinct "click" tactile sensation and a slight sound, providing the user with clear tactile and auditory feedback. At this time, the grip 113 is slightly locked at this angle position, indicating to the user that it has been rotated to the predetermined locking or unlocking position.

[0074] Please see Figure 13 In some embodiments, the connecting plate 21 of the power supply box 20 has a clear indicator mark 214 around the through hole 211. The indicator mark 214 corresponds to the rotation angle of the grip 113. When the grip 113 is rotated to the locked position, the reference point on its exterior or on the knob is aligned with the locked indicator mark 214, visually indicating that the lock 10 is currently in the locked state; when the grip 113 is rotated to the unlocked position, its reference point is aligned with the unlocked indicator mark 214, thereby indicating the unlocked state.

[0075] In summary, this embodiment provides a lock 10 and a display device 100. The rotating part 11 of the lock 10 is rotatably mounted on the power supply box 20 of the display device 100, and the locking part 12 of the lock 10 is fixed to the housing frame 30 of the display device 100. The locking part 112 on the locking rod 111 of the rotating part 11 can extend into the locking part 12 on the housing frame 30. The locking part 12 is provided with a first limiting part 122 and a second limiting part 123. The two limiting parts can form a clear rotation guide path, so that the rotation angle of the locking rod 111 changes synchronously with the locking (unlocking) displacement. The user only needs to rotate the grip part 113 to move the locking rod 111 toward or away from the locking part 12 to complete the locking and unlocking of the power supply box 20. The lock 10 has a simple overall structure, is easy to operate, has high locking reliability, and has good processing adaptability and practical value.
