Description

Technical Field

[0001] This utility model relates to the technical field of expandable fire alarm controller UI modules, specifically expandable fire alarm controller UI modules. Background Technology

[0002] A fire is a combustion that is out of control in time or space. It requires three elements to occur: combustible material, oxidizer, and ignition source. Firefighting is mainly achieved by controlling combustible material, isolating oxygen, and reducing temperature.

[0003] The currently used fire alarm controller UI module has an unreasonable design in its connection structure with the 3U chassis. The disassembly process is relatively complicated. Operators usually need to use multiple tools to unscrew multiple scattered fastening screws. Moreover, there are often obstructions around the screws that cannot be loosened, which further increases the difficulty of operation and affects the efficiency of maintenance and replacement. Therefore, there is an urgent need for an expandable fire alarm controller UI module to improve the above problems. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose an expandable fire alarm controller UI module to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides an expandable fire alarm controller UI module, including a UI module body and a self-locking screw. The self-locking screw is provided on the surface of the UI module body. The UI module body includes a front baffle, a protective shell, and an internal board. The tail end of the internal board is equipped with a DIN connector capable of transmitting and receiving I / O information. A handle for easy removal and removal of the protective shell is provided on one side of the front baffle. Screw holes are provided on both the upper and lower sides of the protective shell. A U-shaped chassis adapted to the UI module body is provided on the outer side of the protective shell. Through holes for easy passage of the self-locking screw are provided on the upper and lower sides of the U-shaped chassis.

[0007] The present invention is further configured to include a transmission shaft that drives the captive screw to rotate. A gear is installed at the end of the transmission shaft away from the captive screw, and a rack is provided on one side of the gear. The captive screw and the gear are connected through the transmission shaft, thereby driving the captive screw to connect with the internal thread of the screw hole.

[0008] By adopting the above technical solution, a rack is provided on one side of the gear, which serves to drive the non-detachable screw to rotate through the transmission shaft.

[0009] The present invention is further configured to include a guide frame that drives the transmission shaft to rise and fall, the outer surface of the guide frame is provided with a limiting groove, the outer surface of the transmission shaft is provided with a limiting slot, the limiting slot and the limiting groove are slidably connected, and the guide frame is S-shaped.

[0010] By adopting the above technical solution, the limiting slot and the limiting groove are slidably connected, which plays the role of driving the transmission shaft to slide through the limiting frame, and the limiting shaft can rotate inside the limiting groove.

[0011] The present invention is further configured to include a limiting shaft to prevent gear tilting, a limiting frame to restrict its rotation is provided on the outer side of the limiting shaft, a transmission rod to drive the rack to slide is provided on one side of the limiting frame, and a pull ring to facilitate pulling the transmission rod is installed at one end of the transmission rod, the pull ring being made of hard rubber.

[0012] By adopting the above technical solution, the pull ring is made of hard rubber, which facilitates the sliding of the transmission rod, and the use of hard rubber can effectively prevent hand injury.

[0013] The present invention is further configured such that: the UI module body is powered by a backplane, transmits and receives IO information through the backplane, and extends to an interactive display screen through a DIN connector.

[0014] By adopting the above technical solution, the UI module body is powered by the backplane, thereby ensuring that the UI module body can operate normally and quickly notify staff in the event of a fire.

[0015] The present invention is further configured such that: all the non-detachable screws pass through the through hole and are threaded to the screw hole, and the handle is fixedly connected to one side of the protective shell through the front baffle.

[0016] By adopting the above technical solution, the non-detachable screws all pass through the through-hole threaded connection and connect with the screw hole, which serves to fix the UI module body into the 3U chassis.

[0017] In summary, the beneficial technical effects of this utility model are as follows:

[0018] This expandable fire alarm controller UI module, with its self-locking screws, effectively prevents screw loss during assembly and disassembly, avoiding interference with other modules. The front panel and handle work together to secure the handle to one side of the protective housing, allowing operators to easily remove the UI module from the 3U chassis. An internal board with a DIN connector for transmitting and receiving I / O information allows for rapid expansion to an interactive display screen. The DIN connector enables hot-swapping of the interactive display screen. Through holes on the top and bottom sides of the 3U chassis allow self-locking screws to pass through, with threaded connections inside the screw holes. The UI module is then secured to the 3U chassis using the engagement of the self-locking screws and screw holes. A drive shaft is added for connecting the self-locking screws... The function of the lock-up screw and gear is as follows: through the cooperation of the rack and gear, the lock-up screw is rotated via the drive shaft, thus engaging with the threaded hole. The limit bracket and limit shaft work together to prevent the lock-up screw from tilting when the rack drives the gear. A limit groove is formed inside the guide bracket, and a limit slot is formed inside the drive shaft, with the limit slot and limit groove slidingly connected. The guide bracket then drives the drive shaft to rise and fall, while the limit shaft can also rotate within the limit groove. The cooperation of the drive rod and pull ring can pull or push the rack to slide, thereby driving the gear to rotate, which in turn drives the lock-up screw to rotate. Using this structure, the disassembly steps are significantly shortened, and the UI module can be disassembled and assembled without tools, greatly improving maintenance and replacement efficiency.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] Reference Figure 1 , Figure 2 and Figure 3 This utility model discloses an expandable fire alarm controller UI module, including a UI module body 1 and a captive screw 2. The surface of the UI module body 1 is provided with captive screws 2. The UI module body 1 includes a front baffle 3, a protective shell 4, and an internal board 5. The tail end of the internal board 5 is equipped with a DIN connector 6 that can transmit and receive IO information. A handle 7 is provided on one side of the front baffle 3 to facilitate the removal and removal of the protective shell 4. Screw holes 8 are provided on both the upper and lower sides of the protective shell 4. A 3U chassis 9 adapted to the UI module body 1 is provided on the outer side of the protective shell 4. Through holes 10 are provided on the upper and lower sides of the 3U chassis 9 to facilitate the passage of captive screws 2. In this embodiment, the UI module body 1 plays the role of displaying data, the captive screws 2 play the role of fixing the UI module body 1 inside the 3U chassis 9, and the front baffle 3 plays the role of limiting the depth of the UI module body 1 inside the 3U chassis 9.

[0030] Reference Figure 3 and Figure 4 It also includes a drive shaft 11 that drives the captive screw 2 to rotate. A gear 12 is installed at the end of the drive shaft 11 away from the captive screw 2. A rack 13 is provided on one side of the gear 12. The captive screw 2 and the gear 12 are connected through the drive shaft 11, which drives the captive screw 2 to connect with the internal thread of the screw hole 8. In this embodiment, the drive shaft 11 plays the role of driving the captive screw 2 to slide, the gear 12 plays the role of driving the captive screw 2 to rotate through the drive shaft 11, and the rack 13 plays the role of driving the gear 12 to rotate.

[0031] Reference Figure 4 It also includes a guide frame 14 that drives the transmission shaft 11 to rise and fall. The outer surface of the guide frame 14 is provided with a limiting groove 15, and the outer surface of the transmission shaft 11 is provided with a limiting slot 16. The limiting slot 16 and the limiting groove 15 are slidably connected. The guide frame 14 is S-shaped. In this embodiment, the guide frame 14 plays the role of driving the non-detachable screw 2 to slide through the transmission shaft 11. The limiting groove 15 is opened inside the guide frame 14, and the limiting slot 16 is opened inside the transmission shaft 11, which plays the role of locking the transmission shaft 11 inside the guide frame 14. In the use of the limiting groove 15 and the limiting slot 16, the guide frame 14 and the transmission shaft 11 are not only slidably connected, but the transmission shaft 11 can also rotate inside the limiting groove 15. The S-shaped shape of the guide frame 14 is used to realize the sliding of the transmission shaft 11 by a fixed distance.

[0032] Reference Figure 4 and Figure 5 It also includes a limiting shaft 17 to prevent the gear 12 from tilting. A limiting frame 18 is provided on the outer side of the limiting shaft 17 to limit its rotation. A transmission rod 19 is provided on one side of the limiting frame 18 to drive the rack 13 to slide. A pull ring 20 is installed at one end of the transmission rod 19 to facilitate pulling the transmission rod 19. The pull ring 20 is made of hard rubber. In this embodiment, the limiting shaft 17 is used to prevent the gear 12 from tilting during rotation. The limiting frame 18 ensures that the limiting shaft 17 can only slide up and down during rotation. The transmission rod 19 is used to connect the guide frame 14 and the rack 13 and can drive the rack 13 to slide with the guide frame 14. The pull ring 20 facilitates the application of force to drive the transmission rod 19 to slide.

[0033] Reference Figure 2 and Figure 3 The UI module body 1 is powered by the backplane, and transmits and receives IO information through the backplane. It is also extended to form an interactive display screen through the DIN connector 6. In this embodiment, the UI module body 1 is powered by the backplane, and can be used to work normally and exchange IO information. The DIN connector 6 is used to extend the interactive display screen and transmit data.

[0034] Reference Figure 2 , Figure 3 and Figure 4 The non-detachable screws 2 all pass through the through hole 10 and are threaded to the screw hole 8. The handle 7 is fixedly connected to one side of the protective shell 4 through the front baffle 3. In this embodiment, the through hole 10 facilitates the connection of the threaded part of the non-detachable screw 2 to the screw hole 8, and the handle 7 facilitates the removal and insertion of the UI module body 1 into the 3U chassis 9.

[0035] The implementation principle of this embodiment is as follows:

[0036] Under normal circumstances, the captive screw 2 will be fixed on the upper and lower sides of the 3U chassis 9 and concentric with the through hole 10. The captive screw 2 drives one end of the thread to connect the thread through the through hole 10 to the inside of the screw hole 8, thereby fixing the UI module body 1 inside the 3U chassis 9.

[0037] When it is necessary to remove the UI module body 1 from the 3U chassis 9, the index, middle, and ring fingers should be brought together and then inserted into the pull ring 20. The pull ring 20 is made of hard rubber to prevent injury to the fingers. After inserting the fingers into the pull ring 20, pull the pull ring 20 forcefully. The pull ring 20 drives the transmission rod 19 to slide inside the limit frame 18. Since the rack 13 and the guide frame 14 are both fixedly connected to one side of the transmission rod 19, during the process of pulling the transmission rod 19 through the pull ring 20, the meshing characteristics of the rack 13 and the gear 12 will drive the gear 12 to rotate. The limit shaft 17 is fixedly connected to one end of the gear 12, and the transmission shaft 11 is fixedly connected to the other end of the gear 12 and is not loosened by screws. The nail 2 and the drive shaft 11 are fixedly connected, so that the rack 13 drives the gear 12 to rotate, which will rotate together with the captive screw 2, thus pulling the threaded part of the captive screw 2 out of the screw hole 8. The captive screw 2 mainly relies on the spring to reset, and a very small part will still remain inside the screw hole 8. Therefore, an S-shaped guide bracket 14 is added. Through the limiting groove 15 opened inside the guide bracket 14 and the limiting slot 16 opened inside the drive shaft 11, the drive shaft 11 can be driven to move up and down, thus completely pulling the captive screw 2 out of the screw hole 8, thereby freeing the UI module body 1 from restriction. The handle 7 can be used to pull the UI module body 1 out from the inside of the 3U chassis 9 for repair or replacement.

[0038] As the guide frame 14 drives the transmission shaft 11 to slide up and down, the guide shaft is always concentric with the through hole 10. Since the limit frame 18 is fixedly connected to the upper and lower sides of the 3U chassis 9 and is used to lock the limit shaft 17, it can effectively prevent the gear 12 and other structures from tilting. When the non-removable screw 2 is pulled out or enters the screw hole 8, the limit shaft 17 will not only rotate inside the limit frame 18, but also slide up and down inside it. At the same time, the distance between the rack 13 and the gear 12 will also change. As the guide frame 14 drives the transmission shaft 11 to slide up and down, the limit groove 15 and the limit slot 16 are slidably connected, and the transmission shaft 11 will also rotate inside the limit groove 15. Thus, the non-removable screw 2 moves a fixed distance. When the staff operates all the above steps, they do not need to use any tools to complete the disassembly and assembly of the UI module body 1, and the disassembly and assembly efficiency is much higher than the existing fixed structure.

[0039] When installing the UI module body 1 into the 3U chassis 9, the UI module body 1 needs to be inserted into the 3U chassis 9 first. Then, the transmission rod 19 can be pushed by the pull ring 20. During this process, the threaded part of the non-removable screw 2 will automatically enter the screw hole 8, thereby fixing the UI module body 1 into the 3U chassis 9.

[0040] The UI module body 1 is powered by the backplane and transmits and receives IO information through the backplane. An interactive display screen is extended through the DIN connector 6. The interactive display screen can display the operating status of the UI module body 1 and other modules. In the event of a fire, the interactive display screen will sound an alarm to notify the staff.
