Description

Technical Field

[0001] This utility model relates to the field of indicator light technology, and in particular to a fault indicator light that can be replaced while energized. Background Technology

[0002] Indicator lights are devices that use light to monitor the working or positional status of circuits and electrical equipment. Indicator lights are typically used to reflect the working status of circuits, the working status and positional status of electrical equipment, etc. Equipment is generally equipped with fault indicator lights to indicate whether the equipment has malfunctioned. When the equipment malfunctions, the control system will use the communication network to make the fault indicator light light up, display the fault status, and wait for the staff to perform maintenance.

[0003] Chinese utility model patent CN220728020U discloses a fault indicator light, including a first mounting plate. A protective cover, which is transparent, is hinged to the right side wall of the first mounting plate. A fixing block is installed inside the mounting cover on the right side wall of the first mounting plate. A lamp holder is mounted on the fixing block via a mounting structure, and an indicator light is mounted on the lamp holder. Bolts are installed at all four corners of the first mounting plate, passing through the first mounting plate and threadedly connected to it. Hinges are installed on the front and rear sides of the top left end of the protective cover, with the other side of each hinge mounted on the right side wall of the first fixing plate. A groove is provided at the bottom of the protective cover. A mounting block is installed on the left side wall of the lamp holder, embedded within the fixing block. The mounting block and the fixing block engage with each other, and the outer side wall of the mounting block is slidably connected to the inner side wall of the fixing block. The fixed block corresponding to the block has mounting grooves at both its upper and lower ends. Fixed plates are installed at both the inner and outer ends of the mounting grooves. The front and rear ends of the fixed plates are fixed to the inner walls of the front and rear sides of the mounting grooves. Limiting rods and springs are fixedly installed on the inner walls of the fixed plates. The springs are respectively sleeved on the outside of the limiting rods. The other ends of the limiting rods and springs are fixed to a second mounting plate. A locking block is fixedly installed on the side wall of the second mounting plate away from the limiting rod. The mounting block corresponding to the locking block has locking grooves at both its upper and lower ends. The locking block and locking grooves engage with each other. The outer wall of the locking block is in contact with the locking groove. Connecting rods are fixedly installed on the second mounting plates on both sides of the limiting rod. The other ends of the connecting rods are slidably connected to the inner wall of the baffle. The baffle is located outside the mounting groove. The inner wall of the baffle abuts against the outer wall of the fixed block. A groove is provided on the outer wall of the baffle, and a pull rod is installed within the groove.

[0004] The existing technology requires two fingers to be inserted into the pulls on the upper and lower sides to pull the two pull rings away from each other, so that the two locking blocks disengage from their corresponding slots. Only with the help of another hand can the lamp holder be separated from the fixing block. This operation is inconvenient, especially for some large indicator lights, which require two people to complete the disassembly operation, and also increases the waste of human resources. Utility Model Content

[0005] To address the aforementioned problems, this invention provides a fault indicator light that can be replaced while the circuit is powered on.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a fault indicator light that can be replaced while energized, comprising a mounting plate, an insulating lamp holder fixed to the top of the mounting plate, a lamp tube disposed on the top of the insulating lamp holder, a locking assembly disposed on the mounting plate, the locking assembly comprising a mounting tube fixed to the top of the mounting plate and coaxially disposed with the insulating lamp holder, and a limiting block fixed to the side wall of the lamp tube, the mounting tube and the limiting block being made of insulating material, such as polytetrafluoroethylene, to improve safety when replacing the lamp tube, the side wall of the mounting tube having an L-shaped limiting groove extending to the top of the mounting tube, the limiting block slidingly engaging with the horizontal section of the limiting groove.

[0007] By adopting the above technical solution, the rotating lamp tube drives the limiting block to rotate, so that the limiting block moves along the horizontal section of the limiting groove until the limiting block moves to the vertical section of the limiting groove. At this time, the lamp tube is pulled away from the insulating lamp holder until the limiting block separates from the limiting groove, thus completing the disassembly of the insulating lamp holder and the lamp tube. The whole process can be completed by one person with one hand, which not only saves manpower, but also facilitates the operation of the device.

[0008] Furthermore, the top of the insulating lamp holder has two mounting slots. A conductive component is provided on both the insulating lamp holder and the lamp tube. The conductive component includes a conductive rod fixed to the bottom of the lamp tube and electrically connected to it, and a conductive sheet fixed to the bottom wall of the mounting slot. The conductive rod is inserted into the mounting slot, and the lower end of the conductive rod abuts against the top of the conductive sheet. The conductive sheet is connected to the power circuit. The number of conductive rods, the number of conductive sheets, and the number of mounting slots are all equal and their positions correspond one-to-one. The two mounting slots have different dimensions, and the two conductive rods have different dimensions. Both conductive rods are adapted to their corresponding mounting slots to ensure that both conductive rods can be accurately inserted into their respective mounting slots.

[0009] By adopting the above technical solution, power is transmitted to the conductive plug through the conductive sheet, and then to the lamp tube through the conductive plug, thus enabling the lamp tube to be powered on. Since the conductive sheet is located in the mounting groove, the lamp tube can be replaced while the power is on.

[0010] Furthermore, the mounting plate is provided with a support assembly, which includes an annular plate slidably fitted on the insulating lamp holder and a spring fixed between the annular plate and the mounting plate and in a contracted state. The top of the annular plate is in contact with the bottom of the lamp tube.

[0011] By adopting the above technical solution, since the top of the annular plate is in contact with the bottom of the lamp tube and the spring is in a contracted state, the restoring force generated by the spring is transmitted to the limiting block through the annular plate and the lamp tube, making the connection between the limiting block and the limiting groove more stable.

[0012] Furthermore, the mounting plate is provided with multiple through holes, and a fixing mechanism is provided on the mounting plate. The fixing mechanism includes fixing components, each of which includes three elastic blocks that are fixed to the bottom of the mounting plate and are evenly distributed about the axis of the mounting through holes, a clamping post inserted into the mounting through hole, and an annular disk fixed to the upper end of the clamping post. The inner diameter of the elastic blocks gradually decreases from top to bottom. The number of fixing components is equal to the number of mounting through holes and their positions correspond one-to-one. The fixing mechanism also includes a lifting component for driving the annular disk to rise and fall.

[0013] By adopting the above technical solution, firstly, the elastic block is inserted into the hole opened on the surface of the installation position until the mounting plate is in contact with the surface of the installation position. Then, the lifting component is operated to drive the annular disk to descend, which in turn drives the clamping columns fixed to the annular disk to descend as well. Since the inner diameter of the elastic block gradually decreases from top to bottom, the elastic block deforms towards the inner wall of the hole until the elastic block is in close contact with the inner wall of the hole, thus completing the overall fixation of the device. Then, the lifting component is operated to drive the annular disk to rise, which in turn drives the clamping columns fixed to the annular disk to rise. Since the inner diameter of the elastic block gradually decreases from top to bottom, the elastic block deforms away from the inner wall of the hole until the elastic block separates from the inner wall of the hole. At this point, the elastic block can be removed from the hole, thus completing the overall disassembly of the device. Similarly, this facilitates subsequent replacement of the device.

[0014] Furthermore, the lifting assembly includes an externally threaded tube fixed to the top of the mounting plate by welding and coaxially arranged with the lamp tube, and an internally threaded tube threadedly connected to the externally threaded tube. The bottom of the internally threaded tube is rotatably connected to the top of the annular disc.

[0015] By adopting the above technical solution, rotating the internally threaded tube, since the externally threaded tube is threadedly connected to the internally threaded tube, can cause the annular disk rotatably connected to the internally threaded tube and the clamping column fixed to the annular disk to both descend or rise, thus realizing the operation of disassembling or installing the entire device from the place of use.

[0016] Furthermore, a lampshade is threaded onto the mounting tube. The lampshade is made of insulating transparent plastic, and both the lamp tube and the insulating lamp holder are located inside the lampshade.

[0017] By adopting the above technical solution, the lampshade provides protection for the lamp tube and the insulated lamp holder. The lampshade is made of insulating transparent plastic to allow light to pass through.

[0018] Furthermore, a limiting block is fixed to the bottom of the annular plate, and a limiting groove that slides with the limiting block is provided on the top of the insulating lamp holder.

[0019] By adopting the above technical solution, the setting of the limiting block and the limiting groove improves the stability of the ring plate during movement.

[0020] Furthermore, the surface of the internally threaded tube is provided with multiple grooves.

[0021] By adopting the above technical solution, the probability of slippage when rotating the internally threaded pipe is reduced.

[0022] Furthermore, wavy grooves are provided on the sidewalls of the elastic blocks that are far apart from each other.

[0023] By adopting the above technical solution, the frictional force when the elastic block contacts the inner wall of the through hole at the installation position is improved.

[0024] Furthermore, the abutment post has a frustum-shaped structure, and the outer diameter of the frustum-shaped structure of the abutment post gradually decreases from top to bottom.

[0025] In summary, the present invention has the following beneficial effects: In this application, through the improvement of the prior art, one person can disassemble the lamp tube with one hand, which not only saves manpower, but also facilitates the operation of the device.

Detailed Implementation

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] like Figure 1-6 As shown in the embodiment of this application, a fault indicator light that can be replaced while energized is disclosed, including a mounting plate 1, a locking assembly 4, a conductive assembly 6, a support assembly 8, and a fixing mechanism 10. An insulating lamp holder 2 is fixed to the top of the mounting plate 1, and multiple mounting through holes 9 are provided through the mounting plate 1. A lamp tube 3 is provided on the top of the insulating lamp holder 2, and two mounting grooves 7 are opened on the top of the insulating lamp holder 2. The locking assembly 4 is disposed on the mounting plate 1. The locking assembly 4 includes a mounting tube 41 and a limiting block 42. The mounting tube 41 is fixed to the top of the mounting plate 1 and is coaxially arranged with the insulating lamp holder 2. An L-shaped limiting groove 5 is opened on the side wall of the mounting tube 41 and extends to the top of the mounting tube 41. The limiting block 42 is fixed to the side wall of the lamp tube 3 and slides with the horizontal section of the limiting groove 5. Both the mounting tube 41 and the limiting block 42 are made of insulating material, such as polytetrafluoroethylene, to improve the safety when replacing the lamp tube. Rotating the lamp tube 3 drives the limiting block 42 to rotate, causing the limiting block 42 to move along the horizontal section of the limiting groove 5 until the limiting block 42 moves to the vertical section of the limiting groove 5. At this time, the lamp tube 3 is pulled away from the insulating lamp holder 2 until the limiting block 42 separates from the limiting groove 5, thus completing the disassembly of the insulating lamp holder 2 and the lamp tube 3. The whole process can be completed by one person with one hand, which not only saves manpower, but also facilitates the operation of the device.

[0030] The conductive component 6 is jointly disposed on the insulating lamp holder 2 and the lamp tube 3. The conductive component 6 includes a conductive rod 61 and a conductive sheet 62. The conductive rod 61 is fixed to the bottom of the lamp tube 3 and electrically connected to the lamp tube 3. The conductive rod 61 is inserted into the mounting slot 7, and the lower end of the conductive rod 61 abuts against the top of the conductive sheet 62. The conductive sheet 62 is connected to the power circuit. The number of conductive rods 61, the number of conductive sheets 62, and the number of mounting slots 7 are all equal and their positions correspond one-to-one. The two mounting slots 7 have different sizes, and the two conductive rods 61 have different sizes. Both conductive rods 61 are adapted to the corresponding mounting slots 7 to ensure that the two conductive rods 61 can be accurately inserted into the adapted mounting slots 7. The conductive sheet 62 is fixed to the inner bottom wall of the mounting slot 7. Power is transmitted to the conductive rod 61 through the conductive sheet 62, and then to the lamp tube 3 through the conductive rod 61, thus realizing the operation of energizing the lamp tube 3. Since the conductive sheet 62 is located in the mounting slot 7, the lamp tube 3 can be replaced when the power is on.

[0031] A support assembly 8 is mounted on the mounting plate 1. The support assembly 8 includes an annular plate 81 and a spring 82. The annular plate 81 is slidably fitted onto the insulating lamp holder 2, with the top of the annular plate 81 in contact with the bottom of the lamp tube 3. The spring 82 is fixed between the annular plate 81 and the mounting plate 1 and is in a retracted state. Because the top of the annular plate 81 is in contact with the bottom of the lamp tube 3 and the spring 82 is in a retracted state, the restoring force generated by the spring 82 is transmitted to the limiting block 42 through the annular plate 81 and the lamp tube 3, making the connection between the limiting block 42 and the limiting groove 5 more stable.

[0032] The fixing mechanism 10 is mounted on the mounting plate 1 and includes a fixing component 101 and a lifting component 102. The fixing component 101 includes elastic blocks 1011, abutting posts 1012, and an annular disc 1013. Three elastic blocks 1011 are evenly distributed about the axis of the mounting through holes 9 to ensure uniform force distribution between the abutting posts 1012 and the ground mounting groove during installation. All three elastic blocks 1011 are fixed to the bottom of the mounting plate 1. The inner diameter of the elastic blocks 1011 gradually decreases from top to bottom. The abutting posts 1012 are inserted into the mounting through holes 9. The annular disc 1013 is fixed to the upper end of the abutting posts 1012. The number of fixing components 101 and the number of mounting through holes 9 are equal and their positions correspond one-to-one. First, insert the elastic block 1011 into the hole opened on the surface of the mounting position until the mounting plate 1 is in contact with the surface of the mounting position. Then, operate the lifting assembly 102 to drive the annular disk 1013 to descend, thereby causing the clamping columns 1012 fixed to the annular disk 1013 to descend as well. Since the inner diameter of the elastic block 1011 gradually decreases from top to bottom, the elastic block 1011 deforms towards the inner wall of the hole until it is in close contact with the inner wall of the hole, thus completing the overall fixation of the device. Next, operate the lifting assembly 102 to drive the annular disk 1013 to rise, thereby causing the clamping columns 1012 fixed to the annular disk 1013 to rise as well. Since the inner diameter of the elastic block 1011 gradually decreases from top to bottom, the elastic block 1011 deforms away from the inner wall of the hole until it separates from the inner wall of the hole. At this point, the elastic block 1011 can be removed from the hole, completing the overall disassembly of the device. Similarly, this facilitates subsequent replacement of the device.

[0033] The lifting assembly 102 is used to drive the annular disk 1013 to rise and fall. The lifting assembly 102 includes an externally threaded tube 1021 and an internally threaded tube 1022. The externally threaded tube 1021 is fixed to the top of the mounting plate 1 by welding and is coaxially arranged with the lamp tube 3. The internally threaded tube 1022 is threadedly connected to the externally threaded tube 1021, and the bottom of the internally threaded tube 1022 is rotatably connected to the top of the annular disk 1013. By rotating the internally threaded tube 1022, since the externally threaded tube 1021 is threadedly connected to the internally threaded tube 1022, the annular disk 1013 rotatably connected to the internally threaded tube 1022 and the clamping column 1012 fixed to the annular disk 1013 can both fall or rise, thus realizing the disassembly or installation of the entire device between the user position and the operating position.

[0034] A lampshade 11 is threaded onto the mounting tube 41. The lampshade 11 is made of insulating transparent plastic, and both the lamp tube 3 and the insulating lamp holder 2 are located inside the lampshade 11. The lampshade 11 provides protection for the lamp tube 3 and the insulating lamp holder 2. The lampshade 11 is made of insulating transparent plastic to allow light to pass through it.

[0035] A limiting block 12 is fixed to the bottom of the annular plate 81, and a limiting groove 13 is provided on the top of the insulating lamp holder 2 to slide with the limiting block 12. The setting of the limiting block 12 and the limiting groove 13 improves the stability of the annular plate 81 during movement.

[0036] The surface of the internally threaded tube 1022 has multiple grooves. This reduces the probability of slippage when rotating the internally threaded tube 1022.

[0037] The elastic blocks 1011 have corrugated grooves on their mutually spaced sidewalls. This increases the friction between the elastic blocks 1011 and the inner wall of the through hole at the installation location.

[0038] The clamping post 1012 has a frustum-shaped structure, and the outer diameter of the frustum-shaped structure of the clamping post 1012 gradually decreases from top to bottom.

[0039] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
