Description

Technical Field

[0001] This utility model belongs to the field of fire protection equipment technology, specifically relating to a fire signal transmission and relay device in a building. Background Technology

[0002] There are many types of fire alarm signal transmission devices in buildings, among which manual fire alarms are one. Manual fire alarms mainly consist of temperature sensing elements, conductive elements, alarm signal transmitters, and audible and visual alarm devices. However, it should be noted that although temperature sensing elements (such as thermocouples and thermistors) are common components of fire detectors and are used to sense changes in ambient temperature, some manual fire alarms may not directly rely on temperature sensing elements to trigger the alarm. Instead, the alarm system may be activated directly through manual operation (such as pressing an alarm button).

[0003] The installation height of manual fire alarms shall not be less than 1.3 meters. This standard is usually set based on the average height of normal adults and ease of operation. Therefore, for most adults, operating the alarm at this height will not pose any difficulty or inconvenience.

[0004] It is worth noting that this height standard may pose a practical operational obstacle for certain groups, such as people with dwarfism and children under 1.3 meters tall. These individuals may have difficulty reaching or effectively operating manual fire alarms installed at 1.3 meters or higher due to their height limitations, potentially affecting their ability to respond quickly and protect themselves in emergencies. Therefore, the needs of these special groups should be fully considered when designing and installing fire alarm systems, and appropriate measures should be taken, such as adding low-level alarms or using other forms of fire warning devices, to ensure that all individuals can promptly and effectively report an emergency and seek assistance. Utility Model Content

[0005] The purpose of this invention is to provide a fire alarm signal transmission device for buildings, aiming to solve the practical operational obstacles that may exist for people with dwarfism and children under 1.3 meters in height. These individuals may have difficulty reaching or effectively operating manual fire alarms installed at 1.3 meters or higher due to their height limitations, which may affect their ability to react quickly and protect themselves in emergencies.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fire signal transmission device for buildings, including a fire alarm, wherein a button is installed on the surface of the fire alarm, and a set of symmetrical upper recesses are provided at the upper end of the back of the fire alarm;

[0007] The back of the fire alarm device has a set of symmetrical recesses at the lower end. A mounting plate is movably installed between each upper and lower recess. Each mounting plate has a mounting plate fixedly installed at both ends. A lifting ring is fixedly installed at the bottom of the fire alarm device, and a connecting rope is wound around the lifting ring.

[0008] To enable the fire alarm to be adjusted vertically after being installed on two mounting plates, as a preferred embodiment of this utility model for a building fire signal transmission device, the fire alarm has a mounting groove on its back side wall, a spring is installed inside the mounting groove, a side groove is provided on the outer wall of the mounting plate away from the sliding groove, a fixing plate is fixedly installed on the inner wall of the side groove, the fixing plate is movably installed in the mounting groove on the side away from the side groove, and the surface of the fixing plate is connected to the bottom of the spring.

[0009] In order to prevent the mounting plate from detaching from the upper recess after it is installed inside the upper recess, as a fire signal transmission device in a building according to this utility model, preferably, a protrusion is fixedly installed on one side of the inner wall of the upper recess, and a sliding groove is provided on one side of the outer wall of the mounting plate. The internal size of the sliding groove is adapted to the size of the protrusion, and the mounting plate is installed in the upper recess through the sliding groove and the protrusion.

[0010] In order to connect the two mounting plates together, as a fire signal transmission device in a building according to this utility model, preferably, a connecting rod is fixedly connected between the top ends of the two mounting plates, and the connecting rod and the two mounting plates form an "n" shaped structure.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] When in use, the fire alarm is installed between two mounting plates, and then the mounting plates are fixed to the wall of the building where it is to be installed using mounting feet. When in use, if the operator is too short to press the button, the operator can pull the lifting ring downwards using the connecting rope. When the lifting ring moves downwards, it will move the fire alarm downwards, and the fire alarm will move downwards along the track of the two mounting plates. In this way, the height of the fire alarm can be lowered, so that people who are too short can effectively press the button in an emergency. Attached Figure Description

[0019] 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.

[0020] Please see Figure 1-4 The present invention provides the following technical solution: a fire signal transmission device in a building, including a fire alarm 1, a button 2 installed on the surface of the fire alarm 1, and a set of symmetrical upper recesses 3 opened at the upper end of the back of the fire alarm 1.

[0021] When a fire is discovered, locate the fire alarm 1 and press button 2. The fire alarm 1 transmits the signal to the alarm signal transmitter through the internal conductive element, and finally emits a fire warning signal through the audible and visual alarm device. This will alert people in the vicinity that a fire has occurred. Since this technical solution is a mature existing technology, it will not be described in detail in this application document.

[0022] The fire alarm 1 has a set of symmetrical recesses 4 at the lower back. A mounting plate 5 is movably installed between each upper recess 3 and lower recess 4. A mounting plate 5 is fixedly installed at both ends of each mounting plate 5. A lifting ring 7 is fixedly installed at the bottom of the fire alarm 1, and a connecting rope 8 is wound around the lifting ring 7.

[0023] When the fire alarm 1 is installed on the wall of a building through the mounting plate 5, the fire alarm 1 will have sufficient reserved length for the wiring according to the subsequent pull-down length, so as to ensure that the wiring will not be short-circuited when the fire alarm 1 is pulled down.

[0024] Preferably, the fire alarm 1 has a mounting groove 11 on its back side wall, and a spring 12 is installed inside the mounting groove 11. The mounting plate 5 has a side groove 51 on its outer wall away from the sliding groove 53. A fixing piece 52 is fixedly installed on the inner wall of the side groove 51. The fixing piece 52 is movably installed in the mounting groove 11 on the side away from the side groove 51, and the surface of the fixing piece 52 is connected to the bottom of the spring 12. A protrusion 31 is fixedly installed on one side inner wall of the upper recess 3. A sliding groove 53 is provided on one side outer wall of the mounting plate 5. The internal dimensions of the sliding groove 53 are adapted to the dimensions of the protrusion 31. The mounting plate 5 is installed in the upper recess 3 through the sliding groove 53 and the protrusion 31.

[0025] After the mounting plate 5 is installed inside the upper recess 3 and the lower recess 4, the mounting plate 5 will be restricted by the fixing piece 52 and the protrusion 31, so that the mounting plate 5 cannot be detached from the interior of the upper recess 3 and the lower recess 4.

[0026] In practical use, the fire alarm 1 is first installed between two parallel mounting plates 5. Then, the mounting plates 5 are firmly fixed to the building wall where they are to be installed by using the mounting feet 6. This process ensures the safety and stability of the entire alarm device.

[0027] In practice, operators may encounter situations where their height limits prevent them from directly reaching and pressing button 2 on the fire alarm 1. To address this issue, the fire alarm 1 in this technical solution is equipped with a connecting rope 8 and a lifting ring 7. When the operator finds that their height is insufficient to directly operate button 2, they can easily grab the connecting rope 8 and pull it downwards, causing the lifting ring 7 to descend. The downward movement of the lifting ring 7 will cause the entire fire alarm 1 to move smoothly and steadily downwards along the preset trajectory of the mounting plate 5.

[0028] When the fire alarm 1 moves down, it will drive the spring 12 to move downward through the mounting groove 11. When the spring 12 moves, it will be blocked by the fixing plate 52, so the spring 12 will be compressed. Therefore, when the connecting rope 8 is released after use, the spring 12 will automatically reset, thus sending the fire alarm 1 back to its original position.

[0029] This process not only simplifies operation but, more importantly, greatly improves the usability and inclusiveness of the fire alarm 1. It allows even shorter individuals to quickly and effectively press button 2 in emergencies, triggering the alarm mechanism promptly and saving valuable time for safe evacuation and emergency rescue within the building. This design reflects meticulous consideration of the needs of various groups and technological innovation, ensuring that fire safety equipment can achieve maximum effectiveness for different users.

[0030] Preferably, a connecting rod 54 is fixedly connected between the top ends of the two mounting plates 5, and the connecting rod 54 and the two mounting plates 5 form an "n" shaped structure.

[0031] The two mounting plates 5 are connected into a single structure by a connecting rod 54, which ensures the firmness between the two mounting plates 5.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
