[0001] This utility model relates to the field of fire telephone switchboards, and in particular to a quick-install fire telephone switchboard. Background Technology

[0002] Fire telephones are dedicated communication devices for fire protection systems, essential for fire systems and providing a convenient and rapid means of communication during fires or emergencies. They offer quick and easy communication when a fire alarm sounds, making them indispensable in fire control and alarm systems. Fire telephone systems have dedicated communication lines, allowing on-site personnel to communicate with the fire control room via landlines. The fire control room can communicate with on-site fire telephone extensions through the main switchboard to guide personnel in evacuation and escape, and on-site personnel can also report real-time situations through the extensions. However, existing fire telephone switches often use screws for installation, requiring screwdrivers and other tools, making installation cumbersome and increasing costs. Furthermore, fire telephones in the main switchboard often lack designated placement space, leading to improper placement and affecting subsequent use.

[0003] Chinese Patent Publication No. CN221978983U discloses a fire telephone switchboard with a simple structure, mainly addressing the problems of complex structure and high production cost of existing fire telephone switchboards. This fire telephone switchboard includes a chassis, a circuit board installed inside the chassis, and a telephone handset installed on the front of the chassis. The chassis consists of a front panel and a back cover. The front panel has a display window and a keypad window, and symmetrically arranged fixed edges perpendicular to the panel on the top and bottom sides. Each fixed edge has screw holes for connection with the back cover. The circuit board is fixed to the back of the panel. Through the above design, this utility model has a simple and ingenious structure. The fixed edges on the panel and the surrounding edging of the back cover form a sealed cavity, sealing the circuit board inside. The assembly of the entire fire telephone switchboard is completed by fixing the chassis with screws, simplifying the design process and reducing the overall production cost. This patent requires a large number of screws for fixing, making installation more complex and increasing installation costs.

[0004] Chinese Patent Publication No. CN217693395U discloses a novel fire telephone switchboard, comprising a housing with a connecting assembly inside.

[0007] A quick-installation fire telephone switchboard is constructed, comprising a housing, a chamber within the housing, a control board installed within the chamber, a display screen and indicator lights connected to the control board, and buttons connected to the control board on the housing. The housing is characterized by having a housing groove, a housing installed within the housing groove, a fire telephone connected to the control board housed within the housing, and a buckle on the side of the housing to secure the housing within the housing groove.

[0008] Preferably, the housing is provided with an outer flange, the area of ​​which is larger than the area of ​​the housing groove. When the housing is installed into the housing groove, the housing groove exerts a squeezing force on the locking block, causing the locking buckle to move. When the housing is installed into the housing groove, the squeezing force of the housing groove on the locking buckle disappears, the locking block resets and locks tightly with the housing groove.

[0009] Preferably, gaps are provided on both sides of the housing. When the housing is installed into the housing groove, the housing groove pushes the buckle to move, and the buckle deforms and resets after installation, locking with the housing groove.

[0010] When the housing is installed into the housing slot, the deformation of the side of the housing slot causes the buckle to move, and after installation, the deformation of the housing slot resets, causing the buckle to move and lock into the housing slot.

[0011] Preferably, the side of the housing is provided with ribs, which limit the position of the housing after installation. The housing has a trapezoidal cross-section and is provided with a foolproof part. The fire telephone is connected to the control board via a spring wire.

[0012] Preferably, a support platform is provided inside the housing, and the fire telephone is placed on the support platform. The width of the support platform is smaller than the width of the housing, so that a spring wire cavity is formed inside the housing. The spring wire is placed inside the spring wire cavity, and a limit rib is provided on the inner wall of the housing.

[0013] Preferably, the housing includes a base with an upper opening, a face cover is provided at the base opening, the control board is placed on the base, base limiting plates are provided on the left and right sides of the base, a face cover side end plate is provided on the face cover corresponding to the base limiting plate, the outer wall of the face cover side end plate contacts the inner wall of the base limiting plate, and the face cover extends along the left and right sides to form an extension plate.

[0014] Preferably, the base has base side plates on the front and rear sides, guide posts on the base side plates, and a cover side plate on the cover corresponding to the base side plates. The cover side plates are connected to the side of the base through the guide posts, and the cover side plates and the base side plates are connected by a snap-fit ​​structure.

[0015] Preferably, the upper part of the guide post is an inclined post, the cover side plate includes a first side plate and a second side plate, and an inclined side plate connecting the first side plate and the second side plate, the outer wall of the first side plate is in contact with the inner wall of the base side plate, the second side plate is flush with the base side plate, the first side plate is provided with a latch, and the base side plate is provided with a base latch block corresponding to the latch.

[0016] Preferably, the base has support columns on its inner walls around its perimeter, the support columns limit the position of the control plate, and the upper end of the support columns contacts the lower end face of the base side plate.

[0017] Preferably, magnets are provided at both the housing and the contact area of ​​the fire telephone. A fastening block is provided on the housing to install the magnets on the housing. A detection hole is also provided on the housing, and a sensor for detecting the fire telephone is installed in the detection hole.

[0018] The beneficial effects of this utility model are as follows: By setting elastic buckles on the side of the housing, when the housing is installed into the casing, the elastic buckles deform due to the housing groove. After reaching the maximum deformation point, continued pressing until the elastic buckle returns to its original position with a sound, the housing is installed and secured to the casing. Simultaneously, ribs limit the housing's movement, preventing it from shaking after installation. The trapezoidal housing shape facilitates installation, allowing for quick completion without the need for screws, thus improving production efficiency and reducing production costs. Furthermore, the use of guide pillars and support pillars between the cover and base facilitates the connection and assembly of the cover and base, resulting in a more stable and aesthetically pleasing assembly.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] A preferred embodiment of this utility model is a quick-installation fire telephone switchboard; such as... Figure 1-3 As shown, the device includes a housing 6 with an internal cavity. A control panel 7 is housed within the cavity, along with indicator lights 3 and buttons 4 connected to the control panel. The status of the fire telephone is observed through the indicator lights 3, and dialing or other related controls are performed via the buttons 4. A display screen 2 connected to the control panel 7 is also mounted on the housing 1, displaying information. A fire telephone 1 is also connected to the housing for communication, and the fire telephone is connected to the control panel via a spring wire 100 for signal transmission.

[0033] Specifically, such as Figure 3-8As shown, the housing 6 includes a base 61 with an opening only at the top and an internal cavity, and a cover 60 located at the opening of the base. The control board is installed inside the base cavity, and the indicator lights 3, buttons, and display screen are mounted on the cover and electrically connected to the control board. A step 610 is provided inside the base cavity, positioned in the middle, leaving cavities 613 on both sides of the base cavity. The control board 7 is placed on the step, and electronic components 701 are connected to both sides of the control board, positioned within the cavities, allowing the control board to be stably installed on the step. To facilitate connection between the control board and external devices, terminal holes 611 are provided at the bottom of the step. Corresponding terminal holes are provided on the control board, with connecting terminals 700 extending through the terminal holes and protruding from the base for easy wiring. To reduce the contact area between the control board and the step, reinforcing ribs 616 are provided on the step. These ribs are distributed horizontally and vertically in a staggered pattern, along the bottom of the base. Specifically, staggered reinforcing ribs are distributed on both the step 610 and the bottom of the cavity 613, thereby increasing the strength of the base. Placing the control board on the reinforcing ribs also reduces its contact area, improving its heat dissipation. Furthermore, to facilitate terminal connection, a recess 612 is provided on the outside of the base corresponding to the step. The terminal hole 611 communicates with this recess, allowing the connecting wires to be connected. This facilitates connection and prevents the base from pressing on the connecting wires during installation, improving the base's safety. Support columns 614 are also provided on the inner walls of the base, contacting the control board to prevent it from wobbling.

[0034] Furthermore, such as Figure 4-5 and Figure 8As shown, to facilitate the installation of the faceplate 60 and the base 61, base limiting plates 615 are provided on the left and right sides of the base. The height of the left and right limiting plates is higher than that of the top and bottom sides. Faceplate side end plates 604 are provided on the left and right sides of the faceplate corresponding to the base limiting plates 615. When the faceplate is connected to the base, the inner side of the base limiting plate and the outer side of the faceplate side end plate are in contact with each other. At the same time, the upper end of the support column is in contact with the lower end 601 of the faceplate side plate, and the support column supports and limits the faceplate. When the faceplate side end plate is in contact with the support column, the faceplate and the base are connected in place, which facilitates the installation and connection of the faceplate and the base. To facilitate insertion of the faceplate into the base, the faceplate side plate includes a second side plate 6012 and a first side plate 6010, as well as an inclined connecting plate 6011 connecting the first and second side plates. The inclined connecting plate ensures that the distance between the two sets of first side plates is less than the distance between the two sets of second side plates, and the distance between the two sets of second side plates is equal to the distance between the base side plates. When the faceplate is inserted into the base, the inner wall of the first side plate contacts the outer wall of the base side plate until the lower end of the faceplate side plate 601 rests on the support column. At this point, the second side plate is positioned above the base side plate, making the second side plate and the faceplate side plate flush. To further facilitate insertion, a guide post 618 is provided on the base side plate, and an inclined post 6180 is provided above the guide post to guide the faceplate insertion into the base.

[0035] Furthermore, such as Figure 4 and Figure 8 As shown, a base locking block 617 is provided on the side plate of the base, and a corresponding face cover locking slot 602 is provided on the side plate of the face cover 601. When the face cover is connected to the base, the base locking block engages with the face cover locking slot to lock the base and the face cover together. A face cover extension plate 605 is provided on the side of the face cover side plate 604. The face cover extension plate makes the face cover area larger than the base area, and the locking hole is located on the extension plate, making it easier to lock the fire telephone switchboard after it is fixed, and at the same time, the base is not visible, which improves the aesthetics. A locking post 603 is provided on the face cover. The locking post is connected to the control board and provides downward pressure to the control board, making the control board more stable in the base.

[0036] Furthermore, such as Figure 1-3 and Figure 8-11As shown, the cover 60 has a housing groove 600, and the housing 5 is placed in the housing groove. The fire telephone 1 is placed inside the housing. To facilitate the installation of the housing and the base, four sets of housing clips 507 are provided on the side, and an outer flange 502 is provided at the top of the housing. When the housing is inserted through the housing groove, it can be fixed in the housing groove by the housing clips. At the same time, the outer flange is above the housing groove, indicating that the housing is installed in place. The housing clips have gaps 508 on both sides to give them a certain degree of elasticity. During installation, the housing clips can be pushed to move by engaging the housing groove. When the pushing force is removed, the housing clips will return to their original shape and lock into the housing groove. Ribs 506 are also provided on both sides of the housing clips. The ribs are engaged with the housing groove to make the housing tighter and more stable after installation in the housing groove. To facilitate installation, the casing features a trapezoidal guide structure on both sides. This design involves cutting the casing from the side to create a trapezoidal cross-section, allowing for easy insertion into the casing slots and even force application. The casing is inserted along the slots and pressed down parallel to the surface. As the clips contact the slots, the downward pressure gradually increases. A "click" sound indicates the clips have reached their designated position and are securely fastened, preventing the casing from being pulled out. Ribs further prevent the casing from wobbling horizontally or vertically, ensuring greater stability after installation. Additionally, a foolproof end 502 is provided at one end of the casing to prevent reverse installation.

[0037] Furthermore, such as Figure 8-11 As shown, a support platform 500 is provided inside the housing. The width of the support platform is smaller than the width of the housing, leaving a spring wire cavity 509 between the side wall of the support platform and the inner side wall of the housing. The fire telephone is placed on the support platform, and the spring wire can be placed in the spring wire groove for easy collection and placement of the spring wire. To facilitate the fixing of the fire telephone inside the housing, support limiting ribs 504 are provided on the front and rear inner side walls of the housing. The support limiting ribs are L-shaped, and the fire telephone is placed on the support limiting ribs for front and rear limiting. Lateral limiting ribs 511 are provided on the left and right inner side walls of the housing to limit the fire telephone in the left and right directions. A detection hole 501 is provided on the support platform. A pressure sensor or detection sensor can be installed in the detection hole to detect the placement of the fire telephone and provide corresponding status indication in conjunction with indicator lights. The housing is provided with a sound transmission hole 505 corresponding to the sound transmission position of the fire telephone, and a fastening block 510 is provided on the outer wall of the support platform. A magnet (not shown in the figure) can be installed at the fastening block. A corresponding magnet is installed on the fire telephone. The attraction between the magnets can realize the attraction force to place the fire telephone in place, so as to facilitate the placement of the fire telephone.

[0038] It should be understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
