Description

Technical Field

[0001] This utility model belongs to the technical field of mosaic display equipment, specifically relating to a self-locking mosaic indicator. Background Technology

[0002] In industries such as nuclear power, coal, railway, aviation, and chemical engineering, massive mosaic-style instrument control panels often house thousands of instruments. These instruments, each with multiple display functions, work together to ensure the stable operation of the control panel. Therefore, the operational stability of the mosaic-style instrument control panel is closely related to the stability of the instruments installed on it.

[0003] According to the Chinese invention patent application with application number "202310445174.8", the mosaic indicator is simply plugged into the base of the mosaic instrument control panel. Since the mosaic indicator is frequently installed and removed as needed, the connection between the mosaic indicator and the base is very easy to loosen due to frequent installation and removal, which reduces the installation stability of the mosaic indicator and thus affects the working stability of the mosaic instrument control panel. Utility Model Content

[0004] The technical problem to be solved by this utility model is how to improve the installation stability of mosaic indicator. In view of the shortcomings of the prior art, a self-locking mosaic indicator is provided.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A self-locking mosaic indicator includes a display component and a mounting component. The display component includes a light-transmitting plate and an indicator light. A plug is installed within the mounting component. The display component snaps onto the upper open end of the mounting component, and the plug extends out from the lower end face of the mounting component. The indicator light is used to emit light toward the light-transmitting plate. The plug is electrically connected to the indicator light and is used to insert into a base. An insertion rod extends downward from the edge of the mounting component. The lower end of the insertion rod extends horizontally to form a locking portion. The top wall of the locking portion gradually extends downward away from the insertion rod. The locking portion is used to insert into a locking interface of the base.

[0007] Compared to existing technologies, the advantages of this invention include: A self-locking mosaic indicator is formed by a display component and a mounting component. The display component has a light-transmitting plate, while the mounting component houses a plug and an indicator light. The plug can be electrically connected to the indicator light and can be inserted into the base of the mosaic instrument control panel, thus enabling the indicator light to illuminate and extinguish. When the indicator light is on, the light is transmitted through the light-transmitting plate to the display component, achieving an indicating effect and ensuring the normal operation of the mosaic instrument control panel. Furthermore, the display component snaps onto the upper opening of the mounting component, allowing for easy connection between the display component and the mounting component. This connection facilitates both the installation and removal of the display component and the installation of the plug within the mounting component. The plug can extend from the lower end of the mounting component, facilitating insertion into the base and ensuring the self-locking mosaic indicator operates smoothly within the mosaic instrument control panel. The electrical connection stability on the mosaic instrument control panel is improved. Simultaneously, the edge of the mounting component extends downwards to form an insertion rod, and the lower end of the insertion rod extends horizontally to form a locking part. This locking part can be inserted into the locking interface of the base, thereby improving the ease of installation and removal of the self-locking mosaic indicator on the mosaic instrument control panel through locking. Furthermore, the top wall of the locking part gradually extends downwards away from the insertion rod, i.e., it is tilted downwards. After the locking part is inserted into the locking interface, the top wall of the locking part cooperates with the locking interface to prevent the self-locking mosaic indicator from being accidentally detached from the mosaic instrument control panel by external force, achieving self-locking and improving its installation stability on the base. At the same time, when the self-locking mosaic indicator needs to be removed, the external force generates an upward tilting component between the top wall of the locking part and the locking interface, releasing the self-lock, thus facilitating the removal of the self-locking mosaic indicator with less effort.

[0008] Optionally, the mounting assembly includes a mounting shell and a protective shell. The mounting shell is mounted on the lower end of the protective shell, the insertion rod is located on the mounting shell, the protective shell is a hollow structure with openings at the top and bottom, the protective shell has a built-in circuit board, the plug is mounted on the lower end surface of the circuit board, and the indicator light is mounted on the circuit board.

[0009] Optionally, the protective shell includes an upper shell and a lower shell, both of which are hollow structures with openings at the top and bottom, and are fitted together to clamp the circuit board. The upper shell and the lower shell are detachably connected.

[0012] Optionally, the mounting assembly further includes a support plate with a mounting opening for the plug to pass through. The support plate covers the lower opening of the protective shell, and the mounting shell has a support block that engages with the protective shell to clamp the support plate.

[0013] Optionally, the plug has an alignment member on its side wall, and the support plate has an alignment port that communicates with the mounting port and is used for the alignment member to pass through.

[0014] Optionally, the display component further includes a connecting shell, which is a hollow structure with openings at the top and bottom. The light-transmitting plate is installed inside the connecting shell, and the connecting shell is detachably connected to the mounting shell.

[0015] Optionally, the lower end face of the connecting shell is provided with a snap-fit ​​block, and the side wall of the mounting shell is provided with a snap-fit ​​interface, the snap-fit ​​block being used to be installed in the snap-fit ​​interface.

[0027] An embodiment of this utility model provides a self-locking mosaic indicator, including a display component 1 and a mounting component 2; the display component 1 includes a light-transmitting plate 11; the mounting component 2 is equipped with a plug 21 and an indicator light, the display component 1 is snapped onto the upper open end of the mounting component 2, the plug 21 extends out of the lower end face of the mounting component 2, the indicator light is used to emit light toward the light-transmitting plate 11, the plug 21 is electrically connected to the indicator light and is used to insert into the base; the edge of the mounting component 2 extends downward to form an insertion rod 22, the lower end of the insertion rod 22 extends horizontally to form a locking part 221, the top wall of the locking part 221 extends downward away from the insertion rod 22, and the locking part 221 is used to insert into the locking interface of the base.

[0028] In this embodiment, as Figure 1 As shown, a self-locking mosaic indicator is composed of a display component 1 and a mounting component 2. The display component 1 has a light-transmitting plate 11, while the mounting component 2 houses a plug 21 and an indicator light. The plug 21 can be electrically connected to the indicator light and can be inserted into the base of the mosaic instrument control panel, thus enabling the indicator light to illuminate and extinguish. When the indicator light is on, the light is transmitted through the light-transmitting plate 11 to the display component 1, achieving an indication effect and ensuring the normal operation of the mosaic instrument control panel. Furthermore, the display component 1 snaps onto the upper opening of the mounting component 2, allowing for easy connection between the display component 1 and the mounting component 2. This connection facilitates both the installation and removal of the display component 1 on the mounting component 2 and the installation of the plug 21 within the mounting component 2. The plug 21 can extend from the lower end of the mounting component 2, making it easy to insert into the base, thereby ensuring the self-locking mosaic indicator's electrical connection on the mosaic instrument control panel. Connection stability; at the same time, the edge of the mounting component 2 extends downward to form an insertion rod 22, and the lower end of the insertion rod 22 extends horizontally to form a locking part 221. The locking part 221 can be inserted into the locking interface of the base, thereby improving the ease of installation and removal of the self-locking mosaic indicator on the mosaic instrument control panel through the locking method. Moreover, the top wall of the locking part 221 gradually extends downward away from the insertion rod 22, that is, it is set downward. With this setting, after the locking part 221 is inserted into the locking interface, the top wall of the locking part 221 can cooperate with the locking interface to prevent the self-locking mosaic indicator from being dislodged from the mosaic instrument control panel by external force caused by accidental touch, thereby achieving self-locking and improving its installation stability on the base. At the same time, when the self-locking mosaic indicator needs to be removed, the external force generates an upward tilting component force between the top wall of the locking part 221 and the locking interface, releasing the self-locking, thereby making it easier to remove the self-locking mosaic indicator with less effort.

[0029] Optionally, the mounting assembly 2 includes a mounting shell 23 and a protective shell 24. The mounting shell 23 is mounted on the lower end of the protective shell 24, and the insertion rod 22 is located on the mounting shell 23.

The protective shell 24 contains a circuit board 243, and the plug 21 is mounted on the lower end surface of the circuit board 243. The circuit board 243 is electrically connected to the indicator light.

[0030] In this optional embodiment, such as Figure 1 and Figure 2 As shown, to ensure the display stability of the light-transmitting plate 11, a mounting assembly 2 is formed by a mounting shell 23 and a protective shell 24.

The protective shell 24 is a hollow structure with openings at the top and bottom, so that the circuit board 243 can be installed inside the protective shell 24 and the circuit board 243 is protected by the protective shell. On this basis, the plug 21 is installed on the circuit board 243, and the circuit board 243 is electrically connected to the indicator light to form a PCBA light board. After the plug 21 is inserted into the base, the PCBA light board can transmit light through the light-transmitting plate 11 to the display assembly 1, so as to achieve the indication effect of the self-locking mosaic indicator.

[0031] Optionally, the protective shell 24 includes an upper shell 241 and a lower shell 242.

[0032] In this optional embodiment, such as Figure 2 and Figure 3 As shown, to ensure the installation stability of the circuit board 243, an upper housing 241 and a lower housing 242 are arranged to form a protective shell 24. Both the upper housing 241 and the lower housing 242 are hollow structures with openings at the top and bottom, and they clamp the circuit board 243 together. This ensures the positional stability of the circuit board 243 and facilitates the electrical connection between the circuit board 243 and the indicator light through the hollow upper housing 241. At the same time, the upper housing 241 and the lower housing 242 are detachably connected.

[0034] In this optional embodiment, in order to ensure accurate alignment of the upper housing 241 and the lower housing 242, such as Figure 2 and Figure 3 As shown, a first slot 2411 and a first protrusion 2412 are provided on the lower end face of the upper housing 241. Correspondingly, a second slot 2421 and a second protrusion 2422 are provided on the upper end face of the lower housing 242. With this arrangement, when the upper housing 241 and the lower housing 242 are connected, the first protrusion 2412 can be placed in the second slot 2421, and the second protrusion 2422 can be placed in the first slot 2411. This ensures accurate alignment of the upper housing 241 and the lower housing 242, and improves the efficiency of assembling the protective shell 24.

[0035] Optionally, the lower end face of the upper housing 241 is provided with a blind hole, the lower housing 242 is provided with a through hole running vertically through it, the edge of the circuit board 243 is provided with a notch, and the protective shell 24 also includes a connector 244, which is used to pass through the through hole and the notch in sequence and is detachably connected to the blind hole.

[0036] It should be noted that connector 244 is a connecting screw, and correspondingly, the blind hole is a threaded hole. There are four connectors 244, and correspondingly, there are also four through holes, four notches, and four blind holes.

[0037] In this optional embodiment, to further ensure the installation stability of the circuit board 243, such as Figure 2 and Figure 3 As shown, a blind hole is provided on the lower end face of the upper housing 241, and a through hole is provided on the lower housing 242. At the same time, a notch is provided on the edge of the circuit board 243. The protective shell 24 is also provided with a connector 244. The connector 244 can pass through the through hole and the notch in sequence, and then be detachably connected to the blind hole. Thus, the connector 244 achieves a stable connection between the upper housing 241 and the lower housing 242, and the mutual limiting of the connector 244 and the notch further ensures the installation stability of the circuit board 243.

[0038] Optionally, the mounting assembly 2 also includes a support plate 25, which has a mounting opening 251 for the plug 21 to pass through. The support plate 25 covers the lower opening of the protective shell 24. The mounting shell 23 has a support block, which cooperates with the protective shell 24 to clamp the support plate 25.

[0039] In this optional embodiment, such as Figure 2 and Figure 3As shown, in order to ensure the isolation effect of the circuit board 243 and thus the working stability of the self-locking mosaic indicator, the mounting assembly 2 is also provided with a support plate 25. The support plate 25 covers the lower opening of the protective shell 24, thereby achieving protection and isolation of the circuit board 243. On this basis, the support plate 25 is provided with a mounting port 251, and the plug 21 can extend through the mounting port 251, thereby ensuring the stable installation of the plug 21. At the same time, the mounting shell 23 is provided with a support block, which can cooperate with the protective shell 24 to clamp the support plate 25, thereby ensuring the installation stability of the support plate 25 and thus ensuring the isolation effect of the circuit board 243.

[0040] It should be noted that, as Figures 1 to 3 As shown, the support plate 25 also has through holes. Before the protective shell 24 and the circuit board 243 are formed into a whole by the connector 244, the connector 244 passes through the through holes on the support plate 25, so that the protective shell 24, the circuit board 243 and the support plate 25 are formed into a whole. Finally, the support block and the display component 1 are clamped together to achieve stable installation.

[0041] Optionally, the side wall of the plug 21 is provided with an alignment member, and the support plate 25 is also provided with an alignment port 252, which communicates with the mounting port 251 and is used for the alignment member to pass through.

[0042] In this optional embodiment, such as Figure 2 and Figure 3 As shown, in order to ensure the accurate installation of the plug 21, an alignment member is provided on the side wall of the plug 21. Correspondingly, an alignment port 252 is provided on the support plate 25. The alignment port 252 is connected to the mounting port 251 and allows the alignment member to pass through. With this arrangement, when the plug 21 passes through the mounting port 251, the alignment port 252 can cooperate with the alignment member to limit the movement, ensuring the accurate installation of the plug 21.

[0043] Optionally, the display assembly 1 also includes a connecting shell 12, which is a hollow structure with openings at the top and bottom. The light-transmitting plate 11 is installed inside the connecting shell 12, and the connecting shell 12 is detachably connected to the mounting shell 23.

[0044] In this optional embodiment, such as Figure 1 and Figure 2As shown, in order to ensure the structural stability of the light-transmitting plate 11 during installation and thus ensure the indication effect, the display component 1 is also provided with a connecting shell 12. The connecting shell 12 is a hollow structure with openings at the top and bottom. In this way, the light-transmitting plate 11 can be installed inside the connecting shell 12, and the connecting shell 12 protects the light-transmitting plate 11. At the same time, the opening of the connecting shell 12 ensures the indication effect of the indicator light when the light is transmitted through the light-transmitting plate 11. On this basis, the connecting shell 12 can be detachably connected to the mounting shell 23, which can ensure the ease of disassembly and assembly of the self-locking mosaic indicator and the connection stability between the display component 1 and the mounting component 2.

[0045] Optionally, the lower end face of the connecting shell 12 is provided with a snap-fit ​​block 121, and the side wall of the mounting shell 23 is provided with a snap-fit ​​interface 231.
