[0001] This utility model relates to the field of fire protection control technology, specifically to a fire protection linkage control device. Background Technology
[0002] Fire alarm linkage devices are the core control component of a fire protection system. They are responsible for coordinating the automatic response of various fire protection equipment when a fire occurs, ensuring efficient fire suppression and personnel evacuation. They are integrated systems that automatically control fire protection facilities (such as sprinklers, smoke exhaust, and emergency lighting) within a building by triggering preset logic through fire alarm signals.
[0003] In the prior art, such as the fire alarm linkage device with application number 201810675241.4, the device comprises a monitoring linkage device, a rocker arm, a voice controller, a main unit, a fixed base plate, and screw fixing ports. The monitoring linkage device is located below the main unit. The main unit is connected to the monitoring linkage device through the rocker arm. The monitoring linkage device and the main unit cooperate to control the operation of the monitoring linkage device through voice commands.
[0004] In the above, the opening and closing of the fire door is achieved by turning the rocker arm, which basically realizes the function of fire protection. However, after reading the technical solution, it is found that the device has too many screws and fixed base plates. When the device needs to replace internal parts or be disassembled for maintenance, this method will make the device difficult to disassemble and affect normal maintenance. Utility Model Content
[0005] The purpose of this utility model is to provide a fire-fighting linkage control device, which aims to solve the problem of inconvenient maintenance caused by the fixed installation method in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a fire box assembly, the fire box assembly including a top shell, a base shell fitted to the top shell, a stabilizing docking member fitted to the base shell, the stabilizing docking member including a side rod adapted to be installed on the side of the top shell, an outer connecting block provided on the lower surface of the side rod, and a stabilizing cylinder fitted to the side rod, the outer surface of the stabilizing cylinder being fixedly connected to the base shell, and a limiting groove being formed on the inner wall surface of the stabilizing cylinder, the limiting groove being movably engaged with the outer connecting block, and an outer stabilizing member fitted to the base shell.
[0007] The outer stabilizing member includes a placement groove provided on the side of the base shell, an intermediate column is fixedly connected to the inner side of the placement groove, and a first connecting rod is rotatably sleeved on the outer surface of the intermediate column.
[0008] A second link is placed beside the first link. There is a distance between the second link and the first link at the middle rotation point, and the center of the second link is rotatably connected to the intermediate column.
[0009] The top outer surface of the second connecting rod is fixedly connected to a recessed seat, which is an open U-shaped right-angled seat.
[0010] The number of limiting grooves is several, and the several limiting grooves are arranged at equal intervals.
[0011] A straight spring is provided on the bottom upper surface of the stabilizing cylinder, and the center of the straight spring is aligned with the center of the stabilizing cylinder.
[0012] The first and second connecting rods are arranged in an X-shape, and a counterweight is provided on the end face of the second connecting rod.
[0013] The inner side of the insert is engaged with an abutment block, and the top of the abutment block is fixed to the top shell.
[0014] The inner cavity of the base shell is provided with internal components, and a fire extinguishing box is fitted to the side of the internal components.
[0015] The stabilizing cylinder is a cylindrical straight cylinder, and both the stabilizing cylinder and the placement groove are placed vertically.
[0016] Compared with the prior art, the beneficial effects of this utility model are: (1) Through the cooperation of the base shell and the stable docking part, the base shell and the top shell can be stably separated, and through the docking cooperation of the side rod, the outer block and the stable cylinder, the top shell can be vertically separated along the upper surface of the base shell, which facilitates the maintenance and upkeep of the internal components. The disassembly between the shells is convenient, eliminating the trouble of repeated disassembly of the fixed installation. The snap-fit between the outer block and the limiting groove allows the side rod to remain stable when it is separated, avoiding the shaking of the base shell and the top shell during disassembly, reducing the collision and wear of the internal components, and indirectly saving the time for the replacement and maintenance of the internal components. The internal components can be given priority protection. Physical maintenance, along with shortened replacement and maintenance times, ensures better device fastening and installation. The straight spring installed on the upper surface of the inner wall of the stabilizing cylinder provides thrust to the lower surface of the side rod because the side rod is no longer compressed, helping the side rod to be pulled out more quickly. The placement groove allows the first connecting rod to rotate stably on the surface of the middle column. After the internal parts are maintained, the top shell can be pressed along the direction of the placement groove. Through the rotational force, the reaction force acts on the lower surface of the top shell, making the pressing and descent of the top shell more stable and generating downward pressure on the insert. Continuously pulling the top shell will make the pulling force greater than the downward pressure, thereby allowing the abutment block to slide out from inside the insert.
[0017] (2) By setting the insert, the top shell has a buffer point when it is pressed down, which reduces the damage when the top shell is pressed down and indirectly ensures the integrity of the parts when the device is disassembled. In addition, the straight spring is set in the stabilizing cylinder so that the lower surface of the top shell is elastically supported when it is pressed down. Through the continuous balance between the downward pressure and the elastic force, the top shell is finally kept in a fixed position, which reflects the easy and stable disassembly of the device.

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1 and 2This utility model provides a fire alarm linkage control device, including a fire alarm box assembly 100. The fire alarm box assembly 100 includes a top shell 101, a base shell 102 fitted to the top shell 101, and a stabilizing docking member 103 fitted to the base shell 102. The stabilizing docking member 103 includes a side rod 1031 adapted to be installed on the side of the top shell 101. The lower surface of the side rod 1031 is provided with an outer connecting block 1032, and the side rod 1031 is mated with a stabilizing cylinder 1033. The outer surface of the stabilizing cylinder 1033 is fixedly connected to the base shell 102, and a limiting groove 1034 is formed on the inner wall surface of the stabilizing cylinder 1033. The limiting groove 1034 is movably engaged with the outer connecting block 1032. The base shell 102 is fitted with an outer stabilizing member 104.
[0025] In the above, the base shell 102 and the stabilizing docking part 103 cooperate to allow the base shell 102 and the top shell 101 to be stably separated. The side rod 1031, the outer block 1032 and the stabilizing cylinder 1033 are connected to allow the top shell 101 to be vertically separated along the upper surface of the base shell 102. This facilitates the maintenance and upkeep of the internal components 105. The disassembly between the shells is convenient, eliminating the trouble of repeated disassembly of fixed installations. The engagement of the outer block 1032 and the limiting groove 1034 allows the side rod 1031 to remain stable when it is separated, preventing the base shell 102 and the top shell 101 from shaking during disassembly. This reduces the impact and wear on the internal components 105, indirectly saving the replacement and maintenance time of the internal components 105. The internal components 105 can be given priority for physical maintenance, and the shortened replacement and maintenance time also ensures better fastening and installation of the device.
[0026] In this embodiment, the outer stabilizing member 104 includes a placement groove 1041 provided on the side of the base shell 102, an intermediate column 1043 is fixedly connected to the inner side of the placement groove 1041, and a first connecting rod 1042 is rotatably sleeved on the outer surface of the intermediate column 1043.
[0027] Preferably, by setting the placement groove 1041, the first connecting rod 1042 can rotate stably on the surface of the intermediate column 1043. After the internal parts are maintained, the top shell 101 can be pressed along the direction of the placement groove 1041. Through the rotational force, the reaction force is applied to the lower surface of the top shell 101, making the pressing and descent of the top shell 101 more stable. Finally, the lower surface of the top shell 101 is precisely connected with the base shell 102, realizing the integrated installation of the device.
[0028] A second link 1044 is placed beside the first link 1042. There is a distance between the second link 1044 and the first link 1042 at the middle rotation point, and the center of the second link 1044 is rotatably connected to the middle column 1043.
[0029] Preferably, the rotational connection of the second link 1044 to the intermediate column 1043 allows the top shell 101 to receive more rotational force support when pressed down, ensuring that the displacement of the top shell 101 remains vertically upward when pressed down or pulled out. At the same time, the symmetrically arranged first link 1042 and second link 1044 ensure that the end face of the top shell 101 is subjected to balanced force and uniform support. This balance ensures that the top shell 101 will not be crushed, facilitating repeated installation and disassembly and demonstrating the ease of assembly of the device.
[0030] In a further preferred embodiment, such as Figure 3 and Figure 4 As shown, a recessed seat 1045 is fixedly connected to the top outer surface of the second connecting rod 1044. The recessed seat 1045 is a right-angled seat with an open U-shape.
[0031] The number of the limiting grooves 1034 is several, and the distribution of the several limiting grooves 1034 is equidistant.
[0032] A straight spring 1035 is provided on the bottom upper surface of the stabilizing cylinder 1033. The center of the straight spring 1035 is aligned with the center of the stabilizing cylinder 1033. The first connecting rod 1042 and the second connecting rod 1044 are arranged in an X-shape, and a counterweight is provided on the end face of the second connecting rod 1044.
[0033] The use of the insert seat 1045 provides a buffer point when the top shell 101 is pressed down, reducing the risk of damage to the top shell 101 during this process. This indirectly ensures the integrity of the parts during disassembly. The use of a straight spring 1035 inside the stabilizing cylinder 1033 provides elastic support to the lower surface of the top shell 101 when it is pressed down. Through the continuous balance between the downward pressure and the elastic force, the top shell 101 is kept in a fixed position, demonstrating the device's easy and stable disassembly characteristics.
[0034] Furthermore, such as Figure 2 and Figure 4 As shown, the inner side of the insert 1045 is engaged with an abutment block 1046, and the top of the abutment block 1046 is fixed to the top shell 101.
[0035] The inner cavity of the base shell 102 is provided with an internal component 105, and a fire extinguishing box 106 is fitted on the side of the internal component 105.
[0036] The stabilizing cylinder 1033 is a cylindrical straight cylinder, and both the stabilizing cylinder 1033 and the placement groove 1041 are placed vertically.
[0037] It is worth noting that the cooperation between the internal component 105 and the fire extinguishing box 106 enables the device to have fire safety features, and the cylindrical straight tube design of the stabilizing cylinder 1033 can ensure that the top shell 101 is not easily tilted when disassembled, ensuring smooth disassembly.
[0038] Working principle: First, the connection between the fire box assembly 100 and the fire extinguishing box 106 is cut off. Then, the top shell 101 is lifted. The side rod 1031 on the lower surface of the top shell 101 will cause the external block 1032 connected to its side to disengage from the limiting groove 1034 opened on the inner side of the stabilizing cylinder 1033. Multiple limiting grooves 1034 are provided. During the disengagement process, they can help lift and stabilize the external block 1032. The external block 1032 is always pulled out vertically from the upper surface of the base shell 102. The straight spring 1035 installed on the upper surface of the inner wall of the stabilizing cylinder 1033 is further supported by the side rod 1031. Because the side rod 1031 is relieved of its own compression, the straight spring 1035 provides a pushing force to the lower surface of the side rod 1031, which helps the side rod 1031 to be lifted and pulled out more quickly, saving some disassembly time.
[0039] At the same time, the abutment block 1046 installed on the surface of the top shell 101 will drive the insert 1045 to move synchronously. Then, the first connecting rod 1042 and the second connecting rod 1044 installed at the bottom of the insert 1045 will rotate and stretch around the surface of the intermediate column 1043. The end face will generate downward pressure on the insert 1045. The top shell 101 will be continuously pulled up, and the pulling force will be greater than the downward pressure, so that the abutment block 1046 will slide out from the inside of the insert 1045. The top shell 101 will then be completely removed, realizing the maintenance of the internal components 105.
[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
