Description

Technical Field

[0001] This utility model relates to the field of anti-theft technology for display screens, and in particular discloses a wall-mounted anti-theft structure for display screens. Background Technology

[0002] In existing technologies, displays (especially wall-mounted displays used in public places) often face problems such as insufficient anti-theft performance and poor installation stability during installation and fixing. Traditional wall-mounted structures often use simple hooks for suspension or external screws for fixing. Hook suspension is prone to falling off due to external force, while external screw fixing carries the risk that the screws can be easily removed and the entire display screen can be taken off. At the same time, some installation structures lack precise guidance and positioning design, which can easily lead to misalignment during installation, affecting the fixing effect. Moreover, the sealing performance is insufficient, allowing external dust and moisture to enter the display screen through the installation gaps, affecting the service life of the equipment. In addition, the locking components and installation components of existing structures often have a single contact point, which can easily loosen due to uneven stress after long-term use, further reducing the reliability of anti-theft and fixing. Utility Model Content

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a wall-mounted anti-theft structure for a display screen.

[0004] To achieve the above objectives, this utility model provides a wall-mounted anti-theft structure for a display screen, comprising a display panel and a mounting plate for use with the display panel; the side of the mounting plate away from the display panel is used to fix it to an external wall, and the side of the mounting plate near the display panel is provided with a first mounting part, and the side of the display panel near the mounting plate is provided with a first mounting groove; the bottom of the display panel is also provided with a movable locking structure, and the first mounting part protrudes into the first mounting groove; when the locking structure is in the first position, the locking structure locks with the first mounting part, fixing the display panel to the mounting plate; when the locking structure is in the second position, the locking structure disengages from the first mounting part, making it easy to remove the display panel from the mounting plate.

[0005] By engaging the first mounting part of the mounting plate with the first mounting slot of the display panel, and combining the locking structure at the bottom with the locking of the first mounting part, a stable connection between the display panel and the wall is achieved, improving anti-theft performance and avoiding the problems of simple hooks easily falling off or external screws easily being disassembled. In specific implementation, first fix the mounting plate to the wall, then align the first mounting slot of the display panel with the first mounting part of the mounting plate and make the first mounting part penetrate into the inner cavity of the display panel. Finally, by operating the locking structure at the bottom of the display panel, it is locked with the first mounting part, thus completing the installation and fixing of the display panel. The installation process is simple and the connection is reliable.

[0006] The first mounting part includes a first connecting section and a first bent section connected to the first connecting section. The first bent section has a first snap-fit ​​notch on its side for engaging with a locking structure.

[0007] The locking structure includes a lock head and a snap-fit ​​element rotatably mounted on the lock head. The display panel has a clearance hole and a rotating column communicating with the clearance hole. The rotating column has a through hole, and the clearance hole communicates with the through hole of the rotating column. The inner side wall of the rotating column has an internal thread located in the through hole, and the outer surface of the lock head has an external thread that mates with the internal thread. After the lock head passes through the clearance hole and the through hole of the rotating column in sequence, the snap-fit ​​element is rotated to engage with the first snap-fit ​​notch. Rotating the lock head locks the locking structure to the display panel.

[0008] The first mounting section forms a specific force-bearing structure through the cooperation of the first connecting section and the first bending section. Combined with the first snap-fit ​​notch and the snap-fit ​​of the locking structure, multiple stable connections between the mounting section and the locking structure are achieved, improving the overall anti-theft performance and structural strength. In specific implementation, the lock head is passed through the clearance hole of the display panel and the through hole of the rotating column in sequence. The lock head is initially positioned by the cooperation of the external thread of the lock head and the internal thread of the rotating column. Then, the snap-fit ​​element on the lock head is rotated to make it snap-fit ​​with the first snap-fit ​​notch of the first bending section. Finally, the lock head is rotated to completely lock the locking structure and the display panel, thereby achieving reliable fixation of the display panel and the mounting plate. The operation is convenient and the locking effect is stable.

[0009] The latching element includes a base disposed on the lock head, a second connecting section disposed on the base, and a first latching section bent to the second connecting section; the first latching section is used to protrude into the first latching notch.

[0010] With a stable connection between the base and the lock head, the bending structure of the second connecting section and the first snap-fit ​​section can precisely fit the shape of the first snap-fit ​​notch, so that the first snap-fit ​​section and the first snap-fit ​​notch form a surface contact abutment snap-fit, which improves the stability and uniformity of the snap-fit ​​and avoids the problem of easy loosening due to single-point contact. This further enhances the connection reliability between the locking structure and the first mounting part, thereby strengthening the overall anti-theft performance. In specific implementation, the snap-fit ​​element is fixed to the lock head through the base. After the lock head penetrates into the inner cavity of the display panel, rotating the lock head drives the snap-fit ​​element to rotate, so that the bent first snap-fit ​​section is precisely embedded in the first snap-fit ​​notch of the first mounting part. With the support of the second connecting section and the abutment between the first snap-fit ​​section and the notch, a firm snap-fit ​​fit is formed. Combined with the threaded locking of the lock head and the rotating column, double fixation is completed.

[0011] The mounting plate has a second mounting part on the side near the display panel, and the display panel has a second mounting groove on the side near the mounting plate; the second mounting part protrudes into the second mounting groove so that the display panel is hung on the mounting plate.

[0012] By adding a second mounting part and a second mounting slot, a dual mounting and positioning structure is formed with the first mounting part and the first mounting slot. This disperses the force on the display panel, avoiding structural deformation or loosening caused by long-term stress on a single mounting part. This significantly improves the overall stability of the connection between the display panel and the mounting plate. At the same time, the dual snap-fit ​​further enhances the anti-theft effect and reduces the possibility of the display panel being forcibly disassembled. In specific implementation, after the mounting plate is fixed to the wall, when installing the display panel, in addition to inserting the first mounting part into the first mounting slot, the second mounting part is simultaneously aligned with the second mounting slot and penetrates into the inner cavity of the display panel. Through the snap-fit ​​cooperation between the second mounting part and the display panel, it forms a coordinated positioning with the first mounting part in the vertical or horizontal direction, achieving stable mounting of the display panel.

[0013] The second mounting section includes a third connecting section and a first inclined section disposed on the third connecting section; the third connecting section and the first inclined section together form an angle, and the third connecting section is used to support the inner groove sidewall of the second mounting groove that abuts the display panel.

[0014] The second mounting part, through the design of the angle formed between the third connecting section and the first inclined section, can achieve stable support by the contact between the third connecting section and the display panel, distributing the weight load of the display panel. At the same time, the first inclined section can form a limit by fitting and engaging with the inner cavity of the display panel, preventing the display panel from swaying or shifting after installation. It works with the first mounting part to form a multi-directional force balance, further improving the overall stability of the connection. In specific implementation, after the second mounting part penetrates into the inner cavity of the display panel through the second mounting groove, the third connecting section fits against the inner sidewall of the display panel to form a contact support. The first inclined section, relying on the angle structure between itself and the third connecting section, is engaged in the corresponding limiting area of ​​the inner cavity of the display panel, forming a tight fit with the inner sidewall of the second mounting groove. Thus, together with the first mounting part, it achieves dual stable fixation of the display panel.

[0015] The display panel includes a housing, an LED screen mounted on the housing, and a cover plate. The housing includes a first main frame, a first side frame mounted on the upper part of the first main frame, and a second side frame mounted on the lower part of the first main frame. The side frame includes a first main body, a first protrusion mounted on the side of the first main body, and a second limiting notch mounted on the other side of the first main body. The two ends of the LED screen abut against the end faces of the first protrusions of the first side frame and the end faces of the first protrusions of the second side frame, respectively. The free end of the cover plate is provided with a second bending portion, and the cover plate is engaged in the second limiting notch via the second bending portion.

[0016] The display panel housing forms a stable frame through the first main frame, the first side frame, and the second side frame. The first protrusion of the side frame can accurately position and firmly support the LED screen, preventing the LED screen from shifting during installation or use. The cover plate is engaged with the second limiting notch of the side frame through the second bend, which not only protects the internal structure of the housing but also facilitates disassembly and maintenance. At the same time, the overall structural design makes the connection between the LED screen, the housing, and the cover plate tighter, improving the structural strength of the display panel itself and indirectly enhancing the overall stability after wall mounting. In specific implementation, the two ends of the LED screen are first positioned and installed by contacting the first protrusion end faces of the first and second side frames. Then, the second bend of the cover plate is aligned with the second limiting notch of the side frame and engaged to fix the cover plate to the housing, forming a complete display panel structure, providing a stable foundation for subsequent installation with the mounting plate.

[0017] The cover plate has a first closing part and a second closing part on its inner side; the first closing part is connected to the first mounting groove, the second closing part is connected to the second mounting groove, the inner side of the first closing part abuts against the first mounting part, and the inner side of the second closing part abuts against the second mounting part; a first opening is also provided above the first closing part, and the first mounting part protrudes out of the first closing part through the first opening and engages with the locking structure.

[0018] The bottom of both the first cover and the second cover is provided with an inclined guide portion, and the first mounting portion and the second mounting portion slide into the first cover and the second cover respectively through the inclined guide portion.

[0019] The first and second fitting parts on the inner side of the cover plate are connected to the first and second mounting slots respectively and abut against the corresponding mounting parts, forming multiple fitting supports and enhancing the tightness of the connection between the display panel and the mounting plate. The inclined guide part facilitates the quick and accurate sliding of the mounting part into the fitting part, improving installation efficiency. The first opening design of the second fitting part provides reasonable space for the second mounting part to engage with the locking structure, ensuring the effective operation of the locking mechanism. The overall structure further improves installation stability and anti-theft reliability. In specific implementation, when installing the display panel, the first and second mounting parts slide into the corresponding fitting parts along the inclined guide parts at the bottom of the first and second fitting parts respectively, so that the inner side of the fitting part is in close contact with the mounting part. The second mounting part protrudes through the first opening above the second fitting part and engages with the locking structure, achieving a fully and secure installation.

[0020] A sealing ring is provided on the side wall of the clearance hole, and the side wall of the sealing ring abuts against the side wall of the lock head.

[0021] The sealing ring on the side wall of the clearance hole abuts against the side wall of the lock head, effectively filling the gap between the lock head and the clearance hole, thus providing a seal and preventing external dust and moisture from entering the inner cavity of the display panel. This prevents internal components from being affected by moisture and dust accumulation, thus extending their service life. Simultaneously, the sealing ring's contact increases the friction between the lock head and the display panel, further enhancing the stability of the locking structure and reducing the risk of the lock head loosening due to vibration or other external forces. In practice, a sealing ring is pre-installed on the side wall of the clearance hole in the display panel. As the lock head passes through the clearance hole and the through hole of the rotating column, the sealing ring naturally and tightly abuts against the side wall of the lock head. After the locking structure is engaged with the first mounting part and the lock head is threadedly locked to the rotating column, the sealing ring remains in contact with the lock head, creating a continuous and effective sealing and auxiliary fixing effect.

[0022] The beneficial effects of this utility model are as follows: This utility model uses the first and second mounting parts of the hanging plate to cooperate with the first and second mounting slots of the display panel, respectively, and combines the locking structure with the snap-fit ​​locking of the mounting parts to form a synergistic principle of multiple positioning and fixing. Its beneficial effects are: the cooperation of the double mounting parts and mounting slots disperses the force, and the cooperation of the cover part with the counter-support significantly improves the connection stability and avoids the problem of easy loosening of a single structure; the bending snap-fit ​​and threaded locking of the locking structure and the mounting parts form a double locking, and the bending design of the snap-fit ​​element achieves surface contact snap-fit, which greatly enhances the anti-theft performance and prevents forced disassembly; the inclined guide part improves the installation efficiency, and the sealing ring plays a role in dust and water protection and auxiliary anti-loosening, extending the service life of the equipment. At the same time, the overall structure is easy to install, and the components are precisely matched, taking into account stability, anti-theft and practicality. Attached Figure Description

[0033] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0034] Please see Figures 1 to 8 As shown, this utility model discloses a wall-mounted anti-theft structure for a display screen, comprising a display panel 1 and a mounting plate 2 used in conjunction with the display panel 1. The side of the mounting plate 2 away from the display panel 1 is used to fix it to an external wall. The side of the mounting plate 2 near the display panel 1 is provided with a first mounting part 3, and the side of the display panel 1 near the mounting plate 2 is provided with a first mounting groove 4. The bottom of the display panel 1 is also provided with a movable locking structure 5, and the first mounting part 3 protrudes into the first mounting groove 4. When the locking structure 5 is in the first position, the locking structure 5 locks with the first mounting part 3, fixing the display panel 1 to the mounting plate 2. When the locking structure 5 is in the second position, the locking structure 5 disengages from the first mounting part 3, making it easy to remove the display panel 1 from the mounting plate 2.

[0035] By engaging the first mounting part 3 of the mounting plate 2 with the first mounting groove 4 of the display panel 1, and locking the first mounting part 3 with the bottom locking structure 5, a stable connection between the display panel 1 and the wall is achieved, improving the anti-theft performance and avoiding the problems of simple hooks easily falling off or external screws easily being disassembled. In specific implementation, first fix the mounting plate 2 to the wall, then align the first mounting groove 4 of the display panel 1 with the first mounting part 3 of the mounting plate 2 and make the first mounting part 3 penetrate into the inner cavity of the display panel 1. Finally, by operating the locking structure 5 at the bottom of the display panel 1, it is locked with the first mounting part 3, thus completing the installation and fixing of the display panel 1. The installation process is simple and the connection is reliable.

[0036] The first mounting part 3 includes a first connecting section 6 and a first bent section 7 connected to the first connecting section 6. The first bent section 7 has a first snap-fit ​​notch 8 on its side for engaging with the locking structure 5.

[0037] The locking structure 5 includes a lock head 9 and a snap-fit ​​element 11 rotatably mounted on the lock head 9. The display panel 1 is provided with a clearance hole 12 and a rotating column 13 communicating with the clearance hole 12. The rotating column 13 is provided with a through hole, and the clearance hole 12 is connected to the through hole of the rotating column 13. The inner side wall of the rotating column 13 is provided with an internal thread located in the through hole, and the outer surface of the lock head 9 is provided with an external thread that mates with the internal thread. After the lock head 9 passes through the clearance hole 12 and the through hole of the rotating column 13 in sequence, the snap-fit ​​element 11 is rotated to the first snap-fit ​​notch 8 to snap with it. The lock head 9 is rotated to lock the locking structure 5 to the display panel 1.

[0038] The first mounting part 3 forms a specific force-bearing structure through the cooperation of the first connecting section 6 and the first bending section 7. With the cooperation of the first snap-fit ​​notch 8 and the locking structure 5, multiple stable connections between the mounting part and the locking structure 5 are achieved, improving the overall anti-theft performance and structural strength. In specific implementation, the lock head 9 is passed through the clearance hole 12 of the display panel 1 and the through hole of the rotating column 13 in sequence. The lock head 9 is initially positioned by the cooperation of the external thread of the lock head 9 and the internal thread of the rotating column 13. Then, the snap-fit ​​element 11 on the lock head 9 is rotated to make it snap-fit ​​with the first snap-fit ​​notch 8 of the first bending section 7. Finally, the lock head 9 is rotated to completely lock the locking structure 5 and the display panel 1, thereby achieving reliable fixation of the display panel 1 and the hanging plate 2. The operation is convenient and the locking effect is stable.

[0039] The latching element 11 includes a base 14 disposed on the lock head 9, a second connecting section 15 disposed on the base 14, and a first latching section 16 bent to the second connecting section 15; the first latching section 16 is used to protrude into the first latching notch 8.

[0040] The base 14 is stably connected to the lock head 9. The bending structure of the second connecting section 15 and the first snap-fit ​​section 16 can accurately fit the shape of the first snap-fit ​​notch 8, so that the first snap-fit ​​section 16 and the first snap-fit ​​notch 8 form a surface contact snap-fit, which improves the stability and uniformity of the snap-fit ​​and avoids the problem of easy loosening due to single-point contact. This further enhances the connection reliability between the locking structure 5 and the first mounting part 3, thereby strengthening the overall anti-theft performance. In specific implementation, the snap-fit ​​element 11 is fixed to the lock head 9 through the base 14. After the lock head 9 penetrates into the inner cavity of the display panel 1, rotating the lock head 9 drives the snap-fit ​​element 11 to rotate, so that the bent first snap-fit ​​section 16 is just embedded in the first snap-fit ​​notch 8 of the first mounting part 3. With the support of the second connecting section 15 and the contact between the first snap-fit ​​section 16 and the notch, a firm snap-fit ​​fit is formed. With the threaded locking of the lock head 9 and the rotating column 13, double fixation is completed.

[0041] The mounting plate 2 has a second mounting part 17 on the side near the display panel 1, and the display panel 1 has a second mounting groove 18 on the side near the mounting plate 2; the second mounting part 17 protrudes into the second mounting groove 18 so that the display panel 1 is hung on the mounting plate 2.

[0042] By adding a second mounting part 17 and a second mounting groove 18 to cooperate, a dual mounting and positioning structure is formed with the first mounting part 3 and the first mounting groove 4. This disperses the force on the display panel 1, avoids structural deformation or loosening caused by long-term stress on a single mounting part, and significantly improves the overall stability of the connection between the display panel 1 and the mounting plate 2. At the same time, the dual snap-fit ​​also further enhances the anti-theft effect and reduces the possibility of the display panel 1 being forcibly disassembled. In specific implementation, after fixing the mounting plate 2 to the wall, when installing the display panel 1, in addition to inserting the first mounting part 3 into the first mounting groove 4, the second mounting part 17 is simultaneously aligned with the second mounting groove 18 and penetrates into the inner cavity of the display panel 1. Through the snap-fit ​​cooperation between the second mounting part 17 and the display panel 1, a coordinated positioning is formed with the first mounting part 3 in the up-down or left-right direction, so as to achieve stable mounting of the display panel 1.

[0043] The second mounting portion 17 includes a third connecting section 19 and a first inclined section 21 disposed on the third connecting section 19; the third connecting section 19 and the first inclined section 21 together form an angle, and the third connecting section 19 is used to support the inner groove sidewall of the second mounting groove 18 that abuts against the display panel 1.

[0044] The second mounting part 17, through the design of the third connecting section 19 forming an angle with the first inclined section 21, can achieve stable support by using the contact between the third connecting section 19 and the display panel 1, distributing the weight load of the display panel 1. At the same time, the first inclined section 21 can form a limit by fitting and engaging with the inner cavity of the display panel 1, preventing the display panel 1 from swaying or shifting after installation. It works with the first mounting part 3 to form a multi-directional force balance, further improving the overall stability of the connection. In specific implementation, after the second mounting part 17 penetrates into the inner cavity of the display panel 1 through the second mounting groove 18, the third connecting section 19 fits against the inner side wall of the display panel 1 to form a contact support. The first inclined section 21, relying on its angle structure with the third connecting section 19, is engaged in the corresponding limiting area of ​​the inner cavity of the display panel 1, forming a tight fit with the inner side wall of the second mounting groove 18, thereby achieving dual stable fixation of the display panel 1 together with the first mounting part 3.

[0045] The display panel 1 includes a housing, an LED screen 23 disposed on the housing, and a cover plate 24. The housing includes a first main frame 25, a first side frame 26 disposed on the upper part of the first main frame 25, and a second side frame 27 disposed on the lower part of the first main frame 25. The side frame includes a first main body 28, a first protrusion 29 disposed on the side of the first main body 28, and a second limiting notch 31 disposed on the other side of the first main body 28. The two ends of the LED screen 23 abut against the end face of the first protrusion 29 of the first side frame 26 and the end face of the first protrusion 29 of the second side frame 27, respectively. The free end of the cover plate 24 is provided with a second bending portion 100, and the cover plate 24 is engaged in the second limiting notch 31 via the second bending portion 100.

[0046] The housing of the display panel 1 forms a stable frame through the first main frame 25, the first side frame 26, and the second side frame 27. The first protrusion 29 of the side frame can accurately position and stably support the LED screen, preventing the LED screen from shifting during installation or use. The cover plate 24 is engaged with the second limiting notch 31 of the side frame through the second bending part 100, which not only protects the internal structure of the housing but also facilitates disassembly and maintenance. At the same time, the overall structural design makes the connection between the LED screen, the housing, and the cover plate 24 tighter, improving the structural strength of the display panel 1 itself and indirectly enhancing the overall stability after wall mounting. In specific implementation, the two ends of the LED screen are first positioned and installed by contacting the end faces of the first protrusion 29 of the first side frame 26 and the second side frame 27. Then, the second bending part 100 of the cover plate 24 is aligned with the second limiting notch 31 of the side frame and engaged, fixing the cover plate 24 to the housing and forming a complete display panel 1 structure, providing a stable foundation for subsequent installation and cooperation with the mounting plate 2.

[0047] The inner side of the cover plate 24 is provided with a first closing part 32 and a second closing part 33; the first closing part 32 is connected to the first mounting groove 4, and the second closing part 33 is connected to the second mounting groove 18. The inner side of the first closing part 32 abuts against the first mounting part 3, and the inner side of the second closing part 33 abuts against the second mounting part 17. A first opening 34 is also provided above the first closing part 32. The first mounting part 3 protrudes out of the first closing part 32 through the first opening 34 and engages with the locking structure 5.

[0048] The bottom of the first cover portion 32 and the second cover portion 33 are both provided with inclined guide portions 35, and the first mounting portion 3 and the second mounting portion 17 slide into the first cover portion 32 and the second cover portion 33 respectively via the inclined guide portions 35.

[0049] The first and second fitting parts 32 and 33 on the inner side of the cover plate 24 are respectively connected to the first and second mounting grooves 18 and abut against the corresponding mounting parts, forming multiple fitting supports and enhancing the tightness of the connection between the display panel 1 and the mounting plate 2. The inclined guide part 35 facilitates the quick and accurate sliding of the mounting part into the fitting part, improving installation efficiency. The design of the first opening 34 of the second fitting part 33 provides reasonable space for the second mounting part 17 to engage with the locking structure 5, ensuring the effective operation of the locking mechanism. The overall structure further improves the installation stability and anti-theft reliability. In specific implementation, when installing the display panel 1, the first mounting part 3 and the second mounting part 17 slide into the corresponding fitting part along the inclined guide part 35 at the bottom of the first and second fitting parts 32 and 33, respectively, so that the inner side of the fitting part is in close contact with the mounting part. The second mounting part 17 protrudes through the first opening 34 above the second fitting part 33 and engages with the locking structure 5, achieving a fully and secure installation.

[0050] A sealing ring 36 is provided on the side wall of the clearance hole 12, and the side wall of the sealing ring 36 abuts against the side wall of the lock head 9.

[0051] The sealing ring 36 on the side wall of the clearance hole 12 abuts against the side wall of the lock head 9, effectively filling the gap between the lock head 9 and the clearance hole 12, thus providing a seal and preventing external dust and moisture from entering the inner cavity of the display panel 1 through the gap. This prevents internal components from being affected by moisture and dust accumulation, thus extending their service life. At the same time, the abutment of the sealing ring 36 also increases the friction between the lock head 9 and the display panel 1, helping to enhance the stability of the locking structure 5 and reducing the risk of the lock head 9 loosening due to external forces such as vibration. In specific implementation, a sealing ring 36 is pre-set on the side wall of the clearance hole 12 of the display panel 1. When the lock head 9 passes through the clearance hole 12 and the through hole of the rotating column 13 in sequence, the sealing ring 36 will naturally and tightly abut against the side wall of the lock head 9. After the locking structure 5 and the first mounting part 3 are engaged and the lock head 9 and the rotating column 13 are threadedly locked, the sealing ring 36 always remains in contact with the lock head 9, forming a continuous and effective sealing and auxiliary fixing effect.

[0052] The rest of this embodiment is the same as that in Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here.

[0053] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
