Description

Technical Field

[0001] This application belongs to the field of control equipment technology, and more specifically, relates to an external control box and its installation structure. Background Technology

[0002] LED display all-in-one units typically consist of two main parts: the display screen and the controller. The controller is responsible for important functions such as signal processing, power management, and system control. However, in actual installation and maintenance, the controller installation method presents significant operational inconveniences. Due to the controller's considerable weight and its usual location behind the display screen, installers must lift the heavy controller to a designated height to secure it. This manual lifting method is not only time-consuming and labor-intensive but also presents significant installation difficulties. Similarly, later maintenance or controller replacement relies on manual disassembly and transportation, resulting in low maintenance efficiency. Utility Model Content

[0003] The purpose of this application is to provide an external control box and its installation structure to solve the technical problems of high difficulty and low efficiency in the installation and maintenance of control boxes in the prior art.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] An installation structure for an external control box is provided, including a fixing member and a sliding member. The fixing member is installed on an external base and has a slot. The sliding member is slidably inserted into the slot and is installed on the external control box.

[0006] The fixing member is also provided with a movable pin, and the sliding member is provided with at least two insertion holes corresponding to the pin. Each insertion hole is arranged at intervals along the extension direction of the slot. When the pin is inserted into different insertion holes, the external control box has different mounting positions relative to the external base.

[0007] As a further improvement to the above technical solution:

[0008] Optionally, the fastener has a bent portion that bends to one side, and the slot is formed on the inner side of the bent portion.

[0009] Optionally, a first fixing member and a second fixing member are installed on the external base, wherein the opening direction of the bent portion of the first fixing member is opposite to the opening direction of the bent portion of the second fixing member.

[0010] Optionally, at least two fixing members are installed at intervals on the external base, and the number and position of the sliding members installed on the external control box correspond to the fixing members.

[0011] Optionally, the insertion hole is a strip-shaped hole, and the extending direction of the strip-shaped hole intersects with the extending direction of the slot.

[0012] Optionally, the fastener has a through hole, the main body of the pin is located on one side of the fastener, and can extend to the other side of the fastener through the through hole.

[0013] Optionally, both the fixing member and the sliding member are provided with mounting holes. The fixing member is installed on the external base by fasteners installed at the mounting holes, and the sliding member is installed on the external control box by fasteners installed at the mounting holes.

[0014] Optionally, the pin is an indexing pin, which includes a main bolt, a pin shaft, an elastic element, and a handle. The main bolt is connected to the fixing member, the pin shaft is slidably connected to the coaxial pin hole of the main bolt, one end of the pin shaft passes through the fixing member, one end of the pin shaft is connected to the handle, one end of the elastic element is connected to the main bolt, and one end of the elastic element is connected to the pin shaft.

[0015] When the handle is driven by an external force, the pin retracts into the pin hole; when the handle is removed by the external force, the pin extends out of the pin hole.

[0016] Optionally, the sliding member includes an integrally formed sliding plate portion and a base plate portion, wherein the sliding plate portion and the base plate portion are arranged parallel to each other and are respectively disposed on a misaligned plane.

[0017] This application also provides an external control box, including the mounting structure of the external control box described above.

[0018] The beneficial effects of the mounting structure for the external control box provided in this application are as follows:

[0019] The mounting structure of the external control box provided in this application includes a fixing component and a sliding component. The fixing component is mounted on an external base, which may specifically be the back of the display module. The fixing component has a longitudinally extending slot; the sliding component can slide along the slot and is rigidly connected to the control box. The fixing component is equipped with a movable pin, and the sliding component has at least two corresponding insertion holes arranged along the extension direction of the slot. By selectively inserting the pin into the insertion holes at different positions, multiple height adjustments of the control box relative to the display module can be achieved.

[0020] The installation structure of the external control box in this application involves first installing the fixing and sliding parts onto the corresponding external base and control box, respectively. Two installers then work together, each holding one end of the control box. After straightening the drooping network cables and AC cables, they push the control box upwards in a predetermined direction, accurately inserting the pin into the first socket to complete the initial mounting. Subsequently, the network cables, AC cables, keypad, and standby button cables are connected sequentially. After all electrical connections are completed, the temporary fixing is released by pulling out the pin, and the control box is pushed upwards until the pin automatically engages in the second socket for final positioning. Finally, the safety fixing screws are tightened to complete the installation. The entire adjustment process requires no additional tools and can be completed with simple insertion and pushing operations, avoiding the need for prolonged manual lifting of the control box. This significantly reduces the difficulty of installing and maintaining the internal components of the external control box, reducing physical exertion, shortening installation and maintenance time, and improving work efficiency.

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

[0044] like Figure 1 and Figure 2 As shown, this application provides an installation structure for an external control box, which includes a fixing member 1 and a sliding member 2. The fixing member 1 is installed on an external base, which can specifically be the back of the display module 4. The fixing member 1 is provided with a longitudinally extending slot 11; the sliding member 2 can slide and adjust along the slot 11 and is rigidly connected to the control box 3. The fixing member 1 is provided with a movable pin 12, and the sliding member 2 is provided with at least two insertion holes 21 arranged along the extension direction of the slot 11. By selectively inserting the pin 12 into the insertion holes 21 at different positions, the height of the control box 3 relative to the display module 4 can be adjusted to multiple levels.

[0045] The installation structure of the external control box in this application involves first installing the fixing part 1 and the sliding part 2 onto the corresponding external base and control box, respectively. Then, two installers work together, each holding one end of the control box. After straightening the drooping network cables and AC cables, they push the control box in the predetermined direction until the pin 12 is accurately inserted into the first socket 21 to complete the initial mounting. Subsequently, the network cables, AC cables, keypad, and standby button cables are connected sequentially. After all electrical connections are completed, the temporary fixing is released by pulling out the pin 12, and the control box is pushed up until the pin 12 automatically engages in the second socket 21 for final positioning. Finally, the safety fixing screws are tightened to complete the installation. The entire adjustment process requires no additional tools and can be completed with simple insertion and pushing operations, avoiding the need for manual lifting of the control box for extended periods. This significantly reduces the difficulty of installing and maintaining the internal components of the external control box, reducing physical exertion, shortening installation and maintenance time, and improving work efficiency.

[0046] like Figure 5 and Figure 6 As shown in a specific embodiment of this application, the fixing member 1 is manufactured using an integral molding process. Its structure includes a bent portion extending to one side, which is formed into a "U"-shaped bent structure by stamping. The inner side of the bent portion naturally forms a slot 11 for accommodating the sliding member 2. This integral structural design not only ensures the structural strength of the slot 11 but also avoids the stress concentration problems that may occur with traditional welding or assembly methods. The geometry of the bent portion can both meet the smooth sliding requirements of the sliding member 2 and provide a reliable positioning reference for the pin 12, ensuring the positional accuracy of the control box 3 during the mounting process.

[0047] like Figure 8 As shown in a specific embodiment of this application, a first fixing member and a second fixing member are provided on the mounting base, and the two are arranged symmetrically. The opening direction of the bent portion of the first fixing member is 180 degrees opposite to the opening direction of the bent portion of the second fixing member. This symmetrical layout design allows the two fixing members to form a mutually cooperating installation reference. Through this reverse-arranged bent portion structure, the first fixing member and the second fixing member can refer to each other during installation, ensuring the installation accuracy of the control box 3. This arrangement not only improves the accuracy of installation positioning but also enhances the stability of the overall structure, enabling the control box 3 to maintain a uniform stress state after mounting, achieving a more stable support effect.

[0048] like Figure 8As shown, in one specific embodiment of this application, at least two fixing members 1 are provided on the back of the display module 4. These fixing members 1 are evenly distributed at preset intervals on the load-bearing positions of the module frame. The control box 3 is equipped with the same number of sliding members 2, the position of each sliding member 2 matching the installation position of the fixing members 1. By setting multiple fixing members 1 and sliding members 2, the weight of the control box 3 can be evenly distributed to multiple stress points of the display module 4, effectively avoiding the problem of local stress concentration. Through multi-point support, not only is the stability of the overall structure improved, but the load strength requirements of individual connection parts are also significantly reduced, thereby extending the service life of the equipment.

[0049] like Figure 3 and Figure 4 As shown in a specific embodiment of this application, the insertion hole 21 provided on the slider 2 adopts a strip-shaped hole structure. The long axis of the strip-shaped hole forms a certain angle with the extension direction of the slot 11, so that the pin 12 has a greater positional tolerance during insertion, which can effectively compensate for positioning errors caused by installation deviations or manufacturing tolerances. The geometric features of the strip-shaped hole allow the pin 12 to have a certain displacement margin in the long axis direction of the hole, ensuring that even in the presence of assembly errors, the pin 12 can still be smoothly inserted into the insertion hole 21 to complete positioning. This not only improves the reliability of the assembly process, but also reduces the alignment accuracy requirements during installation, while maintaining the precise positioning function of the pin 12 in the extension direction of the slot 11. The cooperation between the strip-shaped hole and the pin 12 ensures both ease of installation and does not affect the stability of the final positioning.

[0050] like Figure 5 and Figure 6 As shown, in one specific embodiment of this application, the fixing member 1 is provided with a through hole structure extending through its body, the through hole extending along the thickness direction of the fixing member 1. The main body of the pin 12 is installed on one side of the fixing member 1, and its axial movement direction coincides with the axis of the through hole. When the pin 12 is in the working state, its main body can extend to the other side of the fixing member 1 through the through hole to achieve a mating connection with the insertion hole 21 on the sliding member 2.

[0051] like Figure 1 and Figure 2 As shown in a specific embodiment of this application, both the fixing member 1 and the sliding member 2 are provided with multiple mounting holes, which are arranged according to a preset spacing and position. The fixing member 1 achieves a rigid connection with the external foundation structure through its mounting holes and fasteners, ensuring the structural stability after installation. The sliding member 2 also forms a reliable connection with the external control box through its mounting holes and fasteners. This connection method ensures assembly accuracy and facilitates disassembly operations during maintenance.

[0052] like Figure 5 and Figure 6As shown, in a specific embodiment of this application, the pin 12 is specifically an indexing pin, which includes a main bolt 121, a pin 122, an elastic element, and a handle 123. The main bolt 121 is fixedly mounted on the fixing member 1, and has a coaxial pin hole inside. The pin 122 is axially slidably disposed in the pin hole of the main bolt 121, with one end of the pin 122 passing through the fixing member 1 and the other end connected to the handle 123. One end of the elastic element is connected to the main bolt 121, and the other end is connected to the pin 122. When an external force is applied to the handle 123, the pin 122 retracts axially along the pin hole; when the external force is released, the restoring force of the elastic element causes the pin 122 to automatically extend out of the pin hole. The preload of the elastic element maintains the stable extended state of the pin 122, ensuring reliable engagement with the insertion hole 21, while allowing for quick unlocking via the handle 123.

[0053] like Figure 3 and Figure 4 As shown, in one specific embodiment of this application, the slider 2 adopts an integrally molded structure, including an integrally formed slider portion 22 and a base portion 23. The slider portion 22 and the base portion 23 are arranged in parallel, but are located on different mounting planes, forming a staggered layout. The slider portion 22 is used to cooperate with the slot 11 of the fixing member 1 to realize the sliding guidance function, while the base portion 23 is fixed to the mounting surface of the control box 3 by mechanical connection. This staggered planar structure allows the slider 2 to adapt to the spatial layout requirements between the control box 3 and the display module 4 while maintaining the structural integrity.

[0054] like Figure 7 and Figure 8 As shown, this application provides an external control box, including the installation structure of the external control box in the above embodiments, and therefore also has the advantages of the installation structure of the external control box in the above embodiments.

[0055] 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.
