Description

Technical Field

[0001] This invention relates to the field of electronic information technology, specifically to a wired alarm controller that is easy to install and remove. Background Technology

[0002] A wired alarm controller is a widely used device in the field of security protection. It is mainly used to receive, process, and display alarm signals from various detectors. It usually consists of an alarm control host, detectors, and signal lines connecting the two. There are many types of wired alarms, the most common of which include combustible gas wired alarms, smoke detectors, and heat detectors. Combustible gas alarms are designed to detect leaks of combustible gases, such as natural gas, liquefied petroleum gas, and hydrogen.

[0003] In existing technologies, when combustible gas detectors use a split-wire system, each detector's signal has its own dedicated transmission channel. During use, different detectors are connected to the alarm's main board to detect combustible gases in the environment and provide feedback. However, as the functions of alarms become increasingly complex, the number of connected wires gradually increases. When the wires lack guidance in the middle, they are prone to tangling and knotting, which not only affects the aesthetics but, more seriously, can cause mutual interference between signals, affecting the accuracy of combustible gas concentration detection. In some places with extremely high safety requirements, such as chemical plants and gas stations, inaccurate detection signals can lead to serious safety accidents.

[0004] Secondly, traditional connection methods lack flexibility when dealing with varying numbers of detectors and their cables. During installation, maintenance, cable replacement, or adding / removing detectors, the tangled wiring makes it difficult for installers to connect the wires quickly and accurately, increasing installation time and difficulty. Furthermore, once installation is complete, if a wiring fault occurs, the tangled wiring makes it difficult for maintenance personnel to quickly locate the fault, often requiring large-scale disassembly of the entire cable system. This is cumbersome, time-consuming, and costly, significantly impacting normal equipment operation. It necessitates spending considerable time troubleshooting and repairing, affecting production efficiency, causing signal interference, and impacting the performance of the alarm system, potentially leading to the risk of combustible gas leaks not being detected and alarmed in a timely manner during maintenance.

[0005] Therefore, a convenient, split-line alarm controller was proposed to solve the above problems. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a conveniently installed and dismantled wired alarm controller to solve the problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a conveniently installed and dismantled split-line alarm controller, comprising: a housing, a main board fixedly connected inside the housing, a collection hole provided below the main board, a cable storage and installation mechanism provided below the main board, and an adaptation and positioning mechanism provided on the cable storage and installation mechanism;

[0008] The cable storage and installation / removal mechanism is used to effectively store different detector cables during the process of connecting the detector and the alarm mainboard, and can flexibly adjust and install the cables according to the specific number of detector cables.

[0009] The adaptive and tidying positioning mechanism is used to clamp and tidy up the cable during the storage process to prevent the cable from becoming tangled and to accommodate cables of different thicknesses.

[0010] Preferably, the cable storage and installation mechanism includes an L-shaped positioning block, which is fixedly connected to the housing. Two guide rods are fixedly connected to the symmetrical planes of the two L-shaped positioning blocks. A control screw is provided between the two guide rods. The control screw is rotatably connected to the L-shaped positioning block. Five assemblies are slidably connected to the guide rods and the outer ring of the control screw. A threaded plug is rotatably connected to the end of each assembly near the smaller L-shaped block of the L-shaped positioning block. The threaded plug is threadedly connected to the control screw. Each of the five assemblies is rotatably connected to a connecting rod on the side near the housing. The connecting rod is rotatably connected to the end of the larger L-shaped block of the L-shaped positioning block.

[0011] Preferably, the cable storage and installation / removal mechanism further includes an installation / removal cavity, which is fixedly connected to the upper and lower sides of the assembly. An arc-shaped block is rotatably connected to the inner wall of the installation / removal cavity. An auxiliary spring is fixedly connected to one end of the arc-shaped block near the installation / removal cavity. The end of the auxiliary spring away from the arc-shaped block is fixedly connected to the installation / removal cavity. A U-shaped body is attached to the side of the assembly away from the housing. Both ends of the side of the U-shaped body near the assembly are fixedly connected with snap-fit ​​buckles.

[0012] Preferably, the adaptive positioning mechanism includes a slide rail, which is fixedly connected to a U-shaped body. A groove is formed in the middle of the slide rail, and a connecting strip is rotatably connected to the groove. Fixed plates are rotatably connected to both ends of the connecting strip. A return torsion spring is fixedly connected to the connecting strip and the fixed plate. A positioning body is fixedly connected to the end of each of the two fixed plates away from the connecting strip. The positioning body is slidably connected to the slide rail. A slide rod is slidably connected to both sides of the middle of the positioning body. A buffer spring is sleeved on the outer ring of the slide rod. The two ends of the buffer spring are fixedly connected to the two positioning bodies respectively. An adapter spring is fixedly connected to the middle of the side of the positioning body that is close to each other. An arc-shaped plate is fixedly connected to the end of the adapter spring away from the positioning body. An abutment rod is fixedly connected to the side of each of the two positioning bodies away from the slide rod.

[0013] Preferably, the L-shaped positioning block is composed of a large L-shaped block and a small L-shaped block, and the L-shaped positioning block has a built-in drive power output terminal that is fixedly connected to the L-shaped positioning block.

[0014] Preferably, the arc-shaped blocks and auxiliary springs are arranged symmetrically in two sets with the center point of the mounting and dismounting cavity as the axis, and the snap-fit ​​buckles are snapped into the two arc-shaped blocks.

[0015] Preferably, the curved plate is made of rubber.

[0016] Compared with the prior art, the present invention provides a conveniently installed and dismantled split-wire alarm controller, which has the following advantages:

[0017] 1. The cable storage and installation mechanism, through the forward and reverse rotation of the control screw, drives the threaded plug to move on the control screw, thereby adjusting the spacing between the assembly. After the detector cable is stored in the arc plate, the cable is installed in a specific position in an orderly manner. When the spacing is reduced, the clamping mechanism is pushed to clamp and fix the cable, avoiding the cable messiness, making cable management more standardized, reducing the risk of misoperation and failure caused by cable disorder, and ensuring the stability of the relative position between detectors. In environments affected by vibration or external forces, the stable spacing helps to reduce the displacement between detectors, thereby ensuring the reliability of cable connection, preventing the adverse effects of detector position changes on cable connection, and improving the stability of the entire alarm system. At the same time, the orderly cable layout also facilitates the quick location of fault points and shortens the troubleshooting time.

[0018] 2. Furthermore, the use of snap-fit ​​buckles and arc-shaped blocks assists in the installation and removal of the U-shaped body and the assembly. The clamping structure is designed for installation and removal based on the number of cables, improving the flexibility of installation and disassembly. In actual installation and use, installers can flexibly select the number and position of the appropriate positioning mechanism according to the specific detectors and their cable quantity and layout, and quickly complete the installation work. When equipment maintenance, cable replacement, or adding or removing detectors is required, it can be easily disassembled without large-scale disassembly of the entire cable system, saving maintenance time and costs and reducing the impact on the normal operation of the equipment.

[0019] 3. Through the adaptation and positioning mechanism, when the positioning body moves closer on the slide rail, the adapter spring centers the arc plate close to the cable. This cable organization and fixation helps maintain the stability of the cable connection, thereby ensuring accurate data transmission. The cooperation of the slide rail, positioning body, arc plate and other structures can organize the cables of the same detector into the same set of arc plates. The orderly cable layout effectively avoids the messy distribution of cables, thereby preventing signal interference caused by the mixing of cables between different detectors, such as poor signal coupling, etc., thus reducing false alarms or inaccurate alarms, and improving the accuracy and reliability of the alarm system. With the help of the adapter spring, the arc plate can adaptively adjust according to the different thicknesses of the cables, so that cables of various specifications can be properly fixed. This function, which adapts to cables of different thicknesses, not only meets the fixing requirements of different detector cables, but also makes it easier to pinpoint the location of faults in individually stored cables. By inspecting the cables of specific detectors, the scope of fault diagnosis can be quickly narrowed down, improving the efficiency of fault diagnosis and facilitating subsequent maintenance and repair work. Furthermore, a stable cable connection can ensure the accurate transmission of combustible gas detection data, avoiding false alarms or data loss due to loose cables or poor contact.

[0040] A further embodiment: Please refer to Figures 5 to 9 As shown:

[0041] The adaptive straightening and positioning mechanism 3 is used to clamp and straighten cables during storage to prevent them from becoming tangled and is compatible with cables of different thicknesses. The adaptive straightening and positioning mechanism 3 includes a slide rail 31, which mainly assists in the horizontal movement of the positioning body 36. The slide rail 31 is fixedly connected to the U-shaped body 210. A groove 32 is provided in the middle of the slide rail 31, and a connecting strip 33 is rotatably connected to the groove 32. Fixed plates 34 are rotatably connected to both ends of the connecting strip 33. Return torsion springs 35 are fixedly connected to the connecting strip 33 and the fixed plates 34.

A slide bar 37 is attached, which is mainly used to assist the stability of the centering movement of the positioning body 36. A buffer spring 38 is sleeved on the outer ring of the slide bar 37. The two ends of the buffer spring 38 are fixedly connected to the two positioning bodies 36 respectively. An adapter spring 39 is fixedly connected to the middle of the side of the positioning body 36 that is close to each other. An arc plate 310 is fixedly connected to the end of the adapter spring 39 that is away from the positioning body 36. The arc plate 310 is mainly used to cooperate with the adapter spring 39 to straighten cables of different thicknesses. The arc plate 310 is made of rubber. A stop rod 311 is fixedly connected to the side of the two positioning bodies 36 that is away from the slide bar 37. The stop rod 311 is mainly used to abut against each other and push the positioning body 36 to center and move, thereby positioning the cable.

[0042] The working principle of all the content in the above embodiments is as follows:

[0043] In the initial state: the detector cable is not connected to the main board 11, the built-in power supply of the L-shaped positioning block 21 is not activated to drive the control screw 23 to rotate, there is a distance between the aggregates 24, and the contact rods 311 do not contact each other.

[0044] The following describes the working process of the cable storage and installation mechanism 2, which effectively stores different detector cables and allows for flexible adjustment and installation based on the specific number of detector cables during the connection of the detectors and the alarm mainboard:

[0045] In use, after the various combustible gas detectors are installed, the cables are threaded into the housing 1 through the collection hole 12. Then, according to the detector type, the cables of the same detector are passed through a set of arc-shaped plates 310 for initial cable collection, to organize and distinguish the cables of various detectors. Then, the other end of the cable is connected to the main board 11. When the external detector detects combustible gas, the detected abnormality is converted into an electrical signal and sent to the main board 11. After the main board 11 receives the alarm signals from each detector, it issues a warning. After each detector is collected and stored in its respective set of arc-shaped plates 310, the built-in power supply of the L-shaped positioning block 21 is activated, and the output end drives the control screw 23 to rotate in the forward direction. When the control screw 23 rotates in the forward direction, the threaded plug 26 is connected to the control screw 23 by a thread, which drives the threaded plug 26 to move towards one end of the large L-shaped block on the control screw 23. As the threaded plug 26 moves, the aggregate 24 slides towards one end of the large L-shaped block through the threaded plug 26. With the assistance of the guide rod 22, horizontal movement is ensured. The connecting rod 25 further connects the aggregates 24. Therefore, when the threaded plug 26 drives the aggregate 24 at one end to move, the other aggregates 24 sliding on the guide rod 22 move closer to each other on the guide rod 22 through the deflection of the connecting rod 25, which gathers the cables scattered in the arc plate 310 closer together and avoids the cables from getting tangled.

[0046] Based on the above, the U-shaped body 210 that is snapped onto the assembly 24 can be installed or removed according to the number of detectors installed. When installing the U-shaped body 210, after aligning the U-shaped body 210 with the assembly 24, it moves towards the assembly 24. The snap fasteners 211 at both ends of the U-shaped body 210 move towards the assembly 24 simultaneously. Then, with the assistance of the installation and removal cavities 27 at both ends of the assembly 24, the snap fasteners 211 gradually approach the arc-shaped blocks 28 inside the installation and removal cavities 27. Under the action of the arc-shaped surface of the snap fasteners 211, they gradually resist the arc-shaped blocks 28 and shift to both sides, causing the auxiliary spring 29 to contract. Then, when the snap fasteners 211 continue to push, the snap fasteners 211 snap into the arc-shaped blocks 28. Under the action of the restoring force of the auxiliary spring 29, the arc-shaped blocks 28 are pushed to return to their original state, and the snap fasteners 211 snap into the two arc-shaped blocks 28, thus completing the installation and removal of the assembly 24 and the installation and removal cavity 27.

[0047] With the cable storage and installation mechanism 2 in place, the threaded plug 26 moves on the control screw 23 under the forward and reverse rotation of the control screw 23, thereby adjusting the spacing between the aggregates 24. After the detector cable is stored in the arc plate 310, the cable is installed in a specific position in an orderly manner. When the spacing is reduced, the clamping mechanism is pushed to clamp and fix the cable, avoiding the cable messiness, making cable management more standardized, reducing the risk of misoperation and failure caused by cable messiness, and ensuring the relative position stability between detectors. In environments affected by vibration or external force, the stable spacing helps to reduce the displacement between detectors, thereby ensuring the reliability of cable connection, preventing the adverse effects of detector position changes on cable connection, and improving the stability of the entire alarm system. At the same time, the orderly cable layout also facilitates the quick location of fault points and shortens the fault troubleshooting time.

[0048] Furthermore, with the cooperation of the snap-fit ​​211 and the arc-shaped block 28, the installation and removal of the U-shaped body 210 and the assembly body 24 are assisted. The installation and removal design of the clamping structure according to different cable quantities improves the flexibility of installation and disassembly. In actual installation and use, installers can flexibly select the number and position of the matching positioning mechanism 3 according to the specific detector and its cable quantity and layout to quickly complete the installation work. When equipment maintenance, cable replacement or detector addition or removal is required, it can be easily disassembled without large-scale disassembly of the entire cable system, saving maintenance time and costs and reducing the impact on normal equipment operation.

[0049] Please refer to the above work process. Figures 1 to 6 .

[0050] The following describes the working process of the fitting and positioning mechanism 3, which clamps and organizes cables during storage to prevent them from becoming tangled and is compatible with cables of different thicknesses:

[0051] In use, according to the above-described motion process, the rotation of the control screw 23 drives multiple assemblies 24 to move closer to each other. Since the U-shaped body 210 is mounted on the assemblies 24, the U-shaped body 210 moves closer to each other synchronously when the assemblies 24 move closer. Then, during the process of the U-shaped body 210 moving closer, the abutment rods 311 set on the U-shaped body 210 move closer to each other synchronously until they are in contact. After the abutment rods 311 are in contact, the abutment force pushes the two positioning bodies 36 to move closer on the slide rail 31 through the abutment rods 311. The centering movement of the two positioning bodies 36 is synchronously pushed by the presence of the adapter spring 39 to move the two arc-shaped plates 310 closer to each other. Since the arc-shaped plates 310 house cables, when the arc-shaped plates 310 are close together... At the same time, the cables stored in the arc plate 310 are constrained, and the cables of the same detector are organized into the same set of arc plates 310 for storage. Further, when the positioning bodies 36 on the U-shaped body 210 approach each other, they simultaneously push the two fixing plates 34 to move relative to each other. The relative movement of the fixing plates 34 pushes the two ends of the linkage bar 33 to deflect respectively, so that the linkage bar 33 rotates on the groove 32. The torsion springs connected to the two ends of the linkage bar 33 and the fixing plates 34 are twisted. When the cables are removed and the storage is released, under the action of the reset torsion spring 35, the two ends of the linkage bar 33 are pushed to deflect in the opposite direction, and then the fixing plates 34 at both ends of the linkage bar 33 are pushed to move towards the two ends of the slide rail 31 to complete the reset operation.

[0052] With the adaptation and positioning mechanism 3 in place, when the positioning body 36 moves closer to the slide rail 31, the adapter spring 39 centers the arc plate 310 closer to the cable. This cable straightening and fixing helps maintain the stability of the cable connection, thereby ensuring accurate data transmission. The cooperation of the slide rail 31, positioning body 36, arc plate 310 and other structures can straighten the cables of the same detector into the same set of arc plates 310 for storage. The straight cable layout effectively avoids the messy distribution of cables, thereby preventing signal interference caused by the mixing of cables between different detectors, such as poor signal coupling, etc., thus reducing false alarms or inaccurate alarms, and improving the accuracy and reliability of the alarm system. With the help of the adapter spring 39, the arc plate 310 can adaptively adjust according to the different thicknesses of the cables, so that cables of various specifications can be properly fixed. This function, which adapts to cables of different thicknesses, not only meets the fixing requirements of different detector cables, but also makes it easier to pinpoint the location of faults in individually stored cables. By inspecting the cables of specific detectors, the scope of fault diagnosis can be quickly narrowed down, improving the efficiency of fault diagnosis and facilitating subsequent maintenance and repair work. Furthermore, a stable cable connection can ensure the accurate transmission of combustible gas detection data, avoiding false alarms or data loss due to loose cables or poor contact.
