[0001] This application belongs to the field of display device technology, and more specifically, relates to a door lock device and a display device. Background Technology

[0002] When installing a fixed display panel in a lightbox, a door lock device is required to secure it. However, in related technologies, the door lock device presents inconvenience for installing and removing the display panel. Summary of the Invention

[0003] The purpose of this application is to provide a door lock device and a display device to improve or solve the technical problem in the related art that the door lock device is inconvenient to install on the display panel.

[0004] To achieve the above objectives, in a first aspect, this application provides a door lock device, comprising: The first item has a first part; And a telescopic mechanism, which is provided on the first piece, with a free end at one end; A first space is provided between the free end and the first part; The free end is provided with an inclined surface, so that when the inclined surface is subjected to a force applied by the mounting member of the display panel in the first direction, the free end moves in the second direction to a first position so that the mounting member moves in the first direction into the first space. When the mounting component is located within the first space, the free end returns to the second position along the second direction so that the free end and the first part lock the mounting component in the first space; The first direction intersects with the second direction, and the first direction is the thickness direction of the mounting component.

[0005] In the above technical solution, the free end of the telescopic mechanism is provided with an inclined surface. When the mounting component of the display panel is subjected to force in the first direction, the free end can move to the first position in the second direction, allowing the mounting component to smoothly enter the first space. Subsequently, the free end can return to the second position to lock the mounting component in the first space. This ingenious design makes the installation process of the display panel simple and convenient, without complicated operating steps or additional tools, greatly improving installation efficiency and reducing installation difficulty.

[0006] Furthermore, the telescopic mechanism includes: A fastener, fixed to the first member, has a receiving cavity; one end of the receiving cavity has a first opening; And an elastic element, extending along the second direction, is disposed in the receiving cavity, one end of which is the free end, and the other end is connected to the interior of the receiving cavity; the free end can extend out from the first opening.

[0007] In the above technical solution, the fixing component is firmly set on the first component, and its receiving cavity provides a dedicated space for the elastic component, so that the elastic component has a clear movement path and spatial restriction during the telescopic movement, avoiding the elastic component from shaking or shifting when subjected to force, and ensuring the stability and reliability of the overall structure of the telescopic mechanism.

[0008] Furthermore, the outer side of the receiving cavity is provided with a second opening extending in a second direction; the elastic element includes: The locking part has one end as the free end, which is used to extend from the first opening; The unlocking part has one end connected to the outside of the locking part, and the other end protrudes from the second opening; The elastic part has one end for connecting to the other end of the locking part, and the other end for connecting to the inner wall of the receiving cavity; When a force is applied to the unlocking part in the second direction, the unlocking part is used to move the free end to a first position so that the mounting part is separated from the first space.

[0009] In the above technical solution, a second opening extending in a second direction is provided on the outer side of the receiving cavity, and the unlocking part of the elastic element protrudes from the second opening, providing an intuitive and easily accessible entry point for the unlocking operation. Users do not need complicated searching or special tools; when unlocking is required, they can directly apply force in the second direction to the unlocking part, greatly simplifying the unlocking process and improving the convenience and efficiency of the operation.

[0010] Furthermore, the first component is provided with a position adjustment part for adjusting the relative position of the first part and the mounting component along a first direction; the position adjustment part and the free end hold the mounting component in the first space.

[0011] In the above technical solution, the position adjustment part, used to adjust the relative position of the first part and the mounting part along the first direction, enables the door lock device to adapt to display panel mounting parts of different thicknesses or positions. In practical applications, the thickness of the mounting parts may vary for display panels of different specifications and models. The position adjustment part allows for flexible adjustment of the relative position of the first part and the mounting part in the first direction, ensuring that regardless of changes in the thickness or position of the mounting part, it can cooperate with the free end to securely lock the mounting part within the first space. This greatly expands the applicability of the door lock device and improves its versatility and compatibility.

[0012] Furthermore, the position adjustment unit includes: Mounting holes are provided in the first part; A threaded connector, wherein the shank of the threaded connector is threadedly connected to the mounting hole to adjust the relative position of the first part and the mounting part along a first direction; The head of the threaded connector and the free end fix the mounting component in the first space.

[0013] In the above technical solution, the shank of the threaded connector is threadedly connected to the mounting hole, and this threaded engagement method enables precise linear adjustment. By rotating the threaded connector, its shank will make precise linear movement along a first direction within the mounting hole, thereby allowing for fine adjustment of the relative position between the first part and the mounting component. Compared to some coarse adjustment methods, this threaded adjustment can meet the needs of scenarios with extremely high requirements for installation position accuracy.

[0014] Secondly, this application provides a display device including the aforementioned door lock device.

[0015] Furthermore, the display device includes a lightbox and a display panel; the lightbox has a lightbox frame; one side of the lightbox frame has a rotating part, and the other side of the lightbox frame is equipped with the door lock device; one side of the display panel is rotatably connected to the lightbox frame through the rotating part; the other side of the display panel is equipped with the mounting component. When the display panel rotates around the rotating part on one side, the mounting member applies a force toward the inclined surface in a first direction to lock the mounting member within the first space.

[0016] In the above technical solution, when the display panel rotates around the rotating part, the mounting component applies a force towards the inclined plane in the first direction, thereby automatically locking itself within the first space. This locking method requires no complicated operation from the user; simply rotating the display panel normally is sufficient to lock it, making the operation very convenient. Furthermore, when unlocking is needed, the mounting component can be disengaged from the first space through appropriate operations, opening the display panel. The entire process is simple and easy to understand, making it convenient for users.

[0017] Furthermore, the first component of the door lock device is provided with a first side and a second side opposite to each other along the first direction, the telescopic mechanism is provided on the first side, and the second side is provided with a fixing plate; the fixing plate is detachably connected to the light box frame along the first direction.

[0018] In the above technical solution, the fixing piece is detachably connected to the light box frame along the first direction. When installing the door lock device, the fixing piece can be fixed to the light box frame with a tool along the first direction, thus avoiding occupying the space between the display panel and the light box frame.

[0019] Furthermore, the rotating part includes a rotating connector, and one side of the display panel is rotatably connected to the lightbox frame through the rotating connector.

[0020] In the above technical solution, by precisely connecting the rotating connector to both the display panel and the lightbox frame, the display panel can rotate around the axis of the rotating connector. This rotating connection method is not only simple and reliable in structure, but also easy to install and disassemble. When maintenance or replacement of the display panel is required, it allows for quick operation and improves work efficiency.

[0021] Furthermore, the first component of the door lock device includes a fixing plate; the fixing plate is detachably connected to the light box frame along a first direction.

[0022] In the above technical solution, the fixing plate provides a clear positioning reference for the connection between the door lock device and the light box frame. During assembly, operators can quickly and accurately align the fixing plate with the corresponding installation position on the light box frame based on the hole positions, shape, and other features on the fixing plate. This precise positioning avoids repeated adjustments due to installation position deviations, greatly shortening assembly time and improving assembly efficiency.

[0023] This application provides a door lock device and a display device, which employs a first component, a telescopic mechanism, and a first space. The free end of the telescopic mechanism is provided with an inclined surface, and the first component is provided with a first part. When the inclined surface of the free end is subjected to a force applied by a mounting member of the display panel along a first direction, the free end moves along a second direction to a first position so that the mounting member moves along the first direction into the first space. When the mounting member is located in the first space, the free end returns to a second position along the second direction so that the free end and the first part lock the mounting member in the first space. Thus, the door lock device of this application can realize convenient installation of the display panel. Attached Figure Description

[0034] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0035] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0036] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0037] 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 that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0038] To improve or solve the technical problem of inconvenient installation of the door lock device 17 on the display panel 15 in related technologies, this application provides a door lock device 17 (see reference). Figures 1-5 As shown, it includes: a first component 1, a telescopic mechanism 3, and a first space 6; the first component 1 has a first part 2; the telescopic mechanism 3 is located on one side of the first component 1, and one end of the telescopic mechanism 3 has a free end 4; the first space 6 is located between the free end 4 and the first part 2; the free end 4 has an inclined surface 5, so that when the inclined surface 5 is subjected to a force applied by the mounting member 7 of the display panel 15 along a first direction, the free end 4 moves along a second direction to a first position 10 so that the mounting member 7 moves along the first direction into the first space 6; when the mounting member 7 is located in the first space 6, the free end 4 returns to a second position 9 along the second direction so that the free end 4 and the first part 2 lock the mounting member 7 in the first space 6; the first direction intersects the second direction, and the first direction is the thickness direction of the mounting member 7.

[0039] See Figure 2 and Figure 4 As shown, the first direction can be the X direction, and the second direction can be the Y direction. A telescopic mechanism 3 is provided on the left side of the first part 1, and a free end 4 is provided on the upper part of the telescopic mechanism 3. A first space 6 is formed between the free end 4 and the first part 2. An inclined surface 5 is provided on the free end 4.

[0040] When the inclined surface 5 is subjected to the X-direction force from the mounting component 7 of the display panel 15, the inclined surface 5 drives the free end 4 to move in the Y-direction until the uppermost end 11 of the free end 4 moves to the first position 10 along the Y-direction. At this time, the mounting component 7 enters the first space 6 under the action of the force.

[0041] Meanwhile, after the mounting component 7 enters the first space 6, since the uppermost end 11 of the free end 4 is not blocked by the mounting component 7, the free end 4 of the telescopic mechanism 3 gradually returns from the first position 10 to the second position 9, thereby fixing the mounting component 7 in the first space 6 and completing the installation of the display panel 15.

[0042] In the above technical solution, the free end 4 of the telescopic mechanism 3 is provided with an inclined surface 5. When the mounting component 7 of the display panel 15 is subjected to force in the first direction, the free end 4 can move to the first position 10 in the second direction, allowing the mounting component 7 to smoothly enter the first space 6. Subsequently, the free end 4 can return to the second position 9 to lock the mounting component 7 in the first space 6. This ingenious design makes the installation process of the display panel 15 simple and convenient, without complicated operating steps or additional tools, greatly improving installation efficiency and reducing installation difficulty.

[0043] Therefore, this application employs a first component 1, a telescopic mechanism 3, and a first space 6; the free end 4 of the telescopic mechanism 3 is provided with an inclined surface 5, and the first component 1 is provided with a first part 2; when the inclined surface 5 of the free end 4 is subjected to a force applied by the mounting member 7 of the display panel 15 along the first direction, the free end 4 moves along the second direction to the first position 10 so that the mounting member 7 moves along the first direction into the first space 6; when the mounting member 7 is located in the first space 6, the free end 4 returns to the second position 9 along the second direction so that the free end 4 and the first part 2 lock the mounting member 7 in the first space 6, thereby enabling the door lock device 17 of this application to achieve convenient installation of the display panel 15.

[0044] Furthermore, the telescopic mechanism 3 includes a fixing member 14 and an elastic member; the fixing member 14 is fixed to the first member 1 and has a receiving cavity; one end of the receiving cavity has a first opening 20; the elastic member extends along the second direction and is disposed in the receiving cavity, one end of the elastic member is a free end 4, and the other end of the elastic member is connected to the interior of the receiving cavity; the free end 4 can extend out from the first opening 20.

[0045] See Figure 1 As shown, the telescopic mechanism 3 includes a fixing member 14 and an elastic member. The upper end of the receiving cavity has a first opening 20. The upper end of the elastic member is provided with a free end 4. The lower end of the elastic member is connected to the interior of the receiving cavity. The free end 4 extends out from the first opening 20.

[0046] In the above technical solution, the fixing member 14 is firmly set on the first member 1. Its accommodating cavity provides a dedicated space for the elastic member, so that the elastic member has a clear movement path and spatial restriction during the telescopic movement, avoiding the elastic member from shaking or shifting when subjected to force, and ensuring the stability and reliability of the overall structure of the telescopic mechanism 3.

[0047] Furthermore, the outer side of the receiving cavity is provided with a second opening 22 extending in the Y direction; the elastic element includes a locking part 23, an unlocking part 12, and an elastic part 21; the upper end of the locking part 23 is a free end 4, and the upper end of the locking part 23 is used to extend out from the first opening 20; one end of the unlocking part 12 is connected to the outer side of the locking part 23, and the other end of the unlocking part 12 extends out from the second opening 22; one end of the elastic part 21 is used to connect to the other end of the locking part 23, and the other end of the elastic part 21 is used to connect to the inner wall of the receiving cavity; when a force is applied to the unlocking part 12 in the Y direction, the unlocking part 12 is used to drive the free end 4 to move to the first position 10, so that the mounting part 7 is separated from the first space 6.

[0048] See Figure 4 As shown, when it is necessary to separate the display panel 15 from the door lock device 17, the unlocking part 12 is pulled down along the Y direction, thereby driving the locking part 23 to move in the Y direction and then pressing the elastic part 21 downward, so that the uppermost end 11 of the free end 4 moves from the second position 9 to the first position 10, thereby facilitating the separation of the mounting part 7 from the first space 6.

[0049] When disassembling the display panel 15, the unlocking part 12 can be turned by hand or tool to compress the elastic part 21 downward along the Y direction, so that the locking part 23 moves downward along the Y direction, and the mounting part 7 can be removed from the first space 6.

[0050] In the above technical solution, a second opening 22 extending in a second direction is provided on the outer side of the receiving cavity, and the unlocking part 12 of the elastic member extends out from the second opening 22, providing an intuitive and easily accessible entrance for the unlocking operation. Users do not need complicated searching or special tools; when unlocking is required, they can directly apply force in the second direction to the unlocking part 12, greatly simplifying the unlocking process and improving the convenience and efficiency of the operation.

[0051] Furthermore, the first part 1 is provided with a position adjustment part for adjusting the relative position of the first part 2 and the mounting part 7 along the first direction; the position adjustment part and the free end 4 hold the mounting part 7 in the first space 6.

[0052] Understandably, the position adjustment unit includes a telescopic rod or a rod that can move in the X-axis, such as a screw or bolt. The tightness of the mounting component 7 within the first space 6 can be adjusted through the cooperation of the position adjustment unit and the free end 4.

[0053] When multiple door lock devices 17 are installed at the same time, the display panel 15 is relatively large, and there will be a height difference between the multiple mounting parts 7 of the display panel 15. When locking, there may be situations where the lock is not tight or the gap is loose. In this case, it is necessary to adjust the position adjustment part, adjust it outward along the X direction to increase the gap, and adjust it inward to decrease the gap, to ensure that all door lock devices 17 can be fully locked without looseness.

[0054] In the above technical solution, the position adjustment part for adjusting the relative position of the first part 2 and the mounting part 7 along the first direction allows the door lock device 17 to adapt to mounting parts 7 of display panels 15 with different thicknesses or positions. In practical applications, the thickness of the mounting part 7 of display panels 15 of different specifications and models may vary. The position adjustment part can flexibly adjust the relative position of the first part 2 and the mounting part 7 in the first direction, ensuring that no matter how the thickness or position of the mounting part 7 changes, it can cooperate with the free end 4 to securely lock the mounting part 7 in the first space 6, greatly expanding the applicability of the door lock device 17 and improving its versatility and compatibility.

[0055] Furthermore, the position adjustment part includes a mounting hole 24 and a threaded connector 25; the mounting hole 24 is provided in the first part 2; the rod of the threaded connector 25 is threadedly connected to the mounting hole 24 to adjust the relative position of the first part 2 and the mounting member 7 in the X direction; the head and free end 4 of the threaded connector 25 fix the mounting member 7 in the first space 6.

[0056] See Figure 1 and Figure 4 As shown, the position adjustment part includes a mounting hole 24 and a threaded connector 25; the threaded connector 25 is installed in the mounting hole 24 along the X direction and is threadedly connected to the mounting hole 24, so that by rotating the threaded connector 25 in the mounting hole 24, the head of the threaded connector 25 moves along the X direction and changes position within the first space 6, thereby realizing the adjustment of the installation position of the mounting part 7 within the first space 6.

[0057] In the above technical solution, the rod of the threaded connector 25 is threadedly connected to the mounting hole 24. This threaded connection enables precise linear adjustment. By rotating the threaded connector 25, its rod will make precise linear movement along a first direction within the mounting hole 24, thereby allowing for fine adjustment of the relative position between the first part 2 and the mounting part 7. Compared to some coarse adjustment methods, this threaded adjustment can meet the needs of scenarios requiring extremely high precision in installation position.

[0058] Alternatively, the threaded connection can be a bolt or a screw.

[0059] Furthermore, the fastener 14 is detachably connected to the outer side of the first piece 1.

[0060] For example, see Figure 1 As shown, the fastener 14 is detachably connected to the first piece 1 through the threaded hole 13.

[0061] In the above technical solution, the detachable connection method allows the fastener 14 and the first piece 1 to be operated separately during installation. The operator can first accurately install the first piece 1 into the predetermined position, for example, by fixing the first piece 1, which includes structures such as the position adjustment part, to a suitable location on the equipment frame, and then easily install the fastener 14 onto the outside of the first piece 1. This step-by-step installation method avoids installation difficulties caused by the complexity of the overall structure, and is especially suitable for scenarios with limited space or restricted installation viewing angles, greatly simplifying the installation process and improving installation efficiency.

[0062] This application also provides a display device 19, see reference. Figures 6-8 As shown, it includes a door lock device 17.

[0063] Furthermore, the display device 19 includes a light box 26 and a display panel 15; the light box 26 is provided with a light box frame 18; a rotating part 16 is provided on the left side of the light box frame 18, and a door lock device 17 is installed on the right side of the light box frame 18; the left side of the display panel 15 is rotatably connected to the light box frame 18 through the rotating part 16; a mounting member 7 is installed on the right side of the display panel 15; when the left side of the display panel 15 rotates around the rotating part 16, the mounting member 7 applies a force in the X direction toward the inclined plane 5 to lock the mounting member 7 in the first space 6.

[0064] For example, on the right locking surface of the light box frame 18, two door lock devices 17 are installed on the same axis, and on the left locking surface of the light box frame 18, two rotating parts 16 are installed on the same axis.

[0065] In the above technical solution, when the display panel 15 rotates around the rotating part 16, the mounting part 7 applies a force towards the inclined surface 5 in the first direction, thereby automatically locking itself within the first space 6. This locking method requires no complex operation from the user; simply rotating the display panel 15 normally is sufficient to lock it, making the operation very convenient. Simultaneously, when unlocking is required, the mounting part 7 can be disengaged from the first space 6 through appropriate operations, opening the display panel 15. The entire process is simple and easy to understand, facilitating user operation. Compared to locking the display panel 15 with screws, this method improves locking efficiency, operability, and convenience; compared to locking the display panel 15 with a key lock, it effectively reduces the structural space.

[0066] Optionally, the rotating part 16 includes a rotating connector, and one side of the display panel 15 is rotatably connected to the light box frame 18 through the rotating part 16.

[0067] In the above technical solution, by precisely connecting the rotating connector to both the display panel and the lightbox frame, the display panel can rotate around the axis of the rotating connector. This rotating connection method is not only simple and reliable in structure, but also easy to install and disassemble. When maintenance or replacement of the display panel is required, it allows for quick operation and improves work efficiency.

[0068] Optionally, the rotating connector includes a hinge.

[0069] In the above technical solution, the hinge structure is relatively compact and occupies less space. It does not excessively increase the overall size and thickness of the equipment, which is conducive to the miniaturization of the equipment.

[0070] The relevant technology uses screws and key locks for fixing. Fixing the display panel 15 to the lightbox 26 using screws and key locks requires tools, which necessitates a relatively large tool operating space within the lightbox 26. However, the space within the lightbox 26 is limited, making it difficult to provide sufficient tool operating space, thus resulting in difficulties in installing the display panel 15.

[0071] To solve the above problems, the first component of the door lock device is provided with a first side and a second side opposite to each other along the first direction, the telescopic mechanism is provided on the first side, and the second side is provided with a fixing plate; the fixing plate is detachably connected to the light box frame along the first direction.

[0072] In the above technical solution, the fixing piece is detachably connected to the light box frame along the first direction. When installing the door lock device, the fixing piece can be fixed to the light box frame with a tool along the first direction, thus avoiding occupying the space between the display panel and the light box frame.

[0073] For example, see Figure 7 and Figure 8 As shown, the first component 1 of the door lock device 17 includes a retaining plate 8. (See reference...) Figure 8 As shown, the first side is located on the front side of the first piece (on the same side as the display panel 15), and the second side of the first piece is located on the rear side. The fixing piece 8 is fixed to the rear side of the first piece, and the fixing piece 8 is detachably connected to the light box frame 18 along the X direction.

[0074] The fixing piece 8 is detachably connected to the light box frame 18 along the X direction; thus, when installing the door lock device 17, the fixing piece 8 can be fixed to the light box frame 18 from the rear side of the first piece along the X direction using a tool, avoiding occupying the space between the display panel 15 and the light box frame 18 arranged along the Z direction as tool operating space.

[0075] For example, the fixing piece 8 is detachably connected to the light box frame 18 along the X direction via a threaded connector. Using this connection method, the threaded connector can be installed and removed along the X direction with a screwdriver when installing and removing the door lock device 17, thereby completing the installation and removal of the door lock device 17.

[0076] In the above technical solution, the fixing piece 8 provides a clear positioning reference for the connection between the door lock device 17 and the light box frame 18. During assembly, the operator can quickly and accurately align the fixing piece 8 with the corresponding installation position on the light box frame 18 based on the hole positions, shape, and other features on the fixing piece 8. This precise positioning avoids repeated adjustments due to installation position deviations, greatly shortening assembly time and improving assembly efficiency.

[0077] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
