Description

Technical Field

[0001] This utility model relates to the field of indicating device technology, and more specifically, to a building safety indicating device. Background Technology

[0002] Safety indicators used in buildings are typically installed on walls and at safety exits to indicate exits to people in emergency situations.

[0003] Some safety indicators are installed on ceilings or high places, mainly for long-distance guidance in daily or non-emergency situations. However, in the event of a fire that produces a large amount of smoke, since smoke or heat rises, these high-altitude indicators will be the first to be engulfed by smoke, causing them to lose their intended guiding effect.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a safety indicator device for buildings.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: The building safety indicator includes a hollow housing, a hollow directional marker slidably connected to the back of the housing, a telescopic component for driving the directional marker to slide along the height direction of the housing, and a receiving groove formed on the side wall of the housing, within which a prompting part is provided. The telescopic component comprises several telescopic rods, one end of which communicates with the interior of the housing, and the other end of which communicates with the interior of the directional indicator. A limiting plate is provided on the bottom surface of the housing, which abuts against the directional indicator and limits the length of the telescopic rods. The limiting plate has high-temperature softening properties. The prompting part includes a clicker and a hammer rod for striking the clicker. The hammer rod slides along the height direction of the receiving groove via an elastic element. A retaining piece that limits the length of the elastic piece is slidably connected in the receiving groove. A pull rope is fixedly connected to the inner wall of the retaining piece away from the receiving groove. The other end of the pull rope is fixedly connected to a pointer.

[0007] The present invention is further configured such that: a through groove is provided inside the telescopic rod, which communicates with the inside of the housing and the inside of the indicator; a plurality of light bulbs are provided inside the indicator; and a wire for supplying power to the light bulbs is provided inside the through groove.

[0008] The present invention is further configured such that: a plurality of winding posts are fixedly connected to the inner wall of the housing, the first wire is wound on the plurality of winding posts, and a plurality of second light bulbs are disposed inside the housing.

[0009] The present invention is further configured such that: a sliding groove for sliding of the snap-fit ​​piece is provided on the side wall of the receiving groove, and the snap-fit ​​piece has elastic deformation properties.

[0010] The present invention is further configured such that: when the snap-fit ​​piece abuts against the hammer rod, the length of the elastic element is at its shortest, the width of the clicker is less than the depth of the receiving groove, and the thickness of the clicker gradually decreases from the center to the periphery.

[0011] The present invention is further configured such that: a connecting piece for fixing the housing is fixedly connected to the top of the back side of the housing, and the thickness of the connecting piece is the same as the thickness of the pointer.

[0012] In summary, this utility model has the following beneficial effects: Since both high temperature and smoke move upwards, and the limiting plate is located on the bottom surface of the housing, the limiting plate will first come into contact with the high temperature and soften. It will then hang down around its connection with the housing. At this time, the limitation of the limiting plate on the indicator disappears, the length of the telescopic rod increases, and the limiting plate will slide downwards under the action of the limiting rod, allowing the limiting plate to move to a lower and unsubmerged place, ensuring a good indicating effect of the device. Furthermore, the setting of the hammer rod and the clicker provides a better prompting effect. Attached Figure Description

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] The building uses safety indicator devices, such as Figure 1 and Figure 2As shown, the device includes a hollow housing 1 containing several light bulbs 2 connected in series via wires 2. The surface of the housing 1 is made of a light-transmitting material, allowing the light from the light bulbs 2 to shine through stably, ensuring good directional performance. A hollow directional marker 2 is slidably connected to the back of the housing 1, containing several light bulbs 1 connected in series via wires 1. Both light bulbs 1 and 2 are individually powered via wires 1 and 2, respectively, to prevent damage to the circuit supplying power to the housing 1 from affecting the power supply to the directional marker 2. A telescopic component is provided on the back of the housing 1 to drive the directional marker 2 to slide along the height of the housing 1, allowing the directional marker 2 to slide downwards under the action of a telescopic rod 4, enabling it to move to a position with less smoke. This ensures that even if the housing 1, located at a higher position, is submerged in smoke, the directional marker 2 can still provide directional guidance.

[0017] like Figures 1-3 As shown, the telescopic component is configured as a multi-section telescopic rod 4, made of aluminum alloy with a fire-retardant coating on its outer wall. Aluminum alloy is characterized by high structural strength and light weight. The fire-retardant coating ensures the normal use of the telescopic rod 4 in a fire environment. Different numbers of telescopic rods 4 can be selected according to the actual height. Each section of the telescopic rod 4 has a groove, which does not extend through the length of a single section. A slider is integrally formed on its outer wall, allowing it to slide within the groove. The groove and slider are used to achieve telescopic movement between the multiple sections of the telescopic rod 4 without adjacent sections becoming disjointed. The telescopic rod 4 has a through groove communicating with the interior of the housing 1 and the interior of the indicator 2. The wire is... Encased within a through groove, the wire 1 is protected from direct exposure to air, preventing it from being worn or contaminated. Several winding posts 10 are fixedly connected to the inner wall of the housing 1, and the wire 1 is wound around the winding posts 10. Since the length of the telescopic rod 4 can be changed, the overall length of the wire 1 needs to be increased. When the telescopic rod 4 is in the retracted state, it will be wound around the winding posts 10, preventing the longer wire 1 from piling up inside the housing 1 and getting tangled with the second wire, thus affecting its sliding in the through groove. When the length of the telescopic rod 4 increases, the indicator 2 will apply a pulling force to the wire 1, causing it to slide over the winding posts 10 and into the through groove, ensuring continuous power supply to the several light bulbs.

[0018] like Figure 1 and Figure 2As shown, the bottom surface of the housing 1 is provided with a limiting plate 5 that abuts against the pointer 2 and limits the length of the telescopic rod 4. In the initial state, the pointer 2 will not protrude from the housing 1, preventing premature exposure and potential damage during daily use. The limiting plate 5 is made of thermoplastic, which has the property of softening at high temperatures. In the initial state, it can maintain a rigid state to provide stable support for the pointer 2. The softening temperature of the limiting plate 5 is between 100°C and... At 150°C, when a fire produces high-temperature gas, the hardness of the limiting plate 5 decreases, causing it to droop downwards at its connection with the housing 1, thus losing its support effect on the indicator 2. Since there is no limiting structure inside the telescopic rod 4, when the support of the limiting plate 5 for the indicator 2 disappears, the indicator 2 will fall downwards under its own weight, thus stretching the telescopic rod 4. The telescopic rod 4 is used to stably fix the indicator 2. The telescopic rod 4 is rigid, and one end of the telescopic rod 4 is fixedly connected to the housing 1. Therefore, the indicator 2 is not easy to shake after being hit, ensuring the stable indication effect of the indicator 2. A damping rod can be added inside the telescopic rod 4 to prevent the indicator 2 from falling too fast and vibrating, which would cause the vibration force to be transmitted to its connection with the telescopic rod 4, reducing the connection strength between the indicator 2 and the telescopic rod 4.

[0019] like Figures 1-3As shown, a receiving groove 3 is provided on the side wall of the housing 1, and a prompting part is provided in the receiving groove 3. The prompting part is placed in the receiving groove 3, and the housing 1 is set at a high position to avoid accidental activation of the prompting part. The prompting part includes a clicker 6 and a hammer rod 7 for striking the clicker 6. The loud sound generated by the prompting part is used to better alert people to the occurrence of a fire. The clicker 6 is made of high tin bronze, and the thickness of the clicker 6 gradually decreases from the center to the periphery. The hammer rod 7 is positioned corresponding to the center of the clicker 6, which allows the vibration to be transmitted from the center to the periphery, thereby generating more overtones. The hammer rod 7 slides along the height direction of the receiving groove 3 via an elastic element, which is a spring. Sliding grooves 11 are provided on both sides of the receiving groove 3 in the width direction. A locking piece 8 for limiting the length of the elastic piece is slidably connected in the sliding groove 11. In the initial state, the locking piece 8 and the hammer rod 7 are connected in a sliding groove 11. When the bottom surfaces of rods 7 abut against each other, the elastic element is in its shortest length state under the pressure applied by the snap-fit ​​piece 8. When the snap-fit ​​piece 8 slides out of the sliding groove 11, the pressure on the elastic element disappears, allowing it to be stretched under its own elastic properties and the pulling force applied by the hammer rod 7. This allows the hammer rod 7 to strike the clicker 6 and produce a cueing sound, enabling people to react more quickly. When the elastic element is compressed for a long time, it stores elastic potential energy. When the elastic element is no longer compressed by the snap-fit ​​piece 8, the potential energy of the compressed elastic element will be converted into kinetic energy and move downward, allowing the hammer rod 7 to strike the clicker 6. However, the elastic element will rush past the equilibrium position under the action of inertia, causing energy to be repeatedly converted between potential energy and kinetic energy, thus forming reciprocating vibration until it is completely consumed by frictional resistance. During this process, the elastic element will extend and contract multiple times, driving the hammer rod 7 to strike the clicker 6 multiple times.

[0020] like Figures 1-3As shown, a pull rope 9 is fixedly connected to the side of the snap-fit ​​piece 8 away from the inner wall of the receiving groove 3. The other end of the pull rope 9 is fixedly connected to the indicator 2. The pull rope 9 does not have elastic deformation properties, but the snap-fit ​​piece 8 does. As the indicator 2 slides downward, the distance between the two ends of the pull rope 9 gradually increases. However, since the length of the pull rope 9 itself does not change, the indicator 2 applies a pulling force to the snap-fit ​​piece 8 through the pull rope 9, allowing the snap-fit ​​piece 8 to slide out of the sliding groove 11. Since the indicator 2 applies a downward pulling force to the snap-fit ​​piece 8, the snap-fit ​​piece 8's elastic deformation properties allow it to better bend downward with the direction of the force, preventing it from being unable to slide out due to its rigidity and abutting against the inner wall of the sliding groove 11. In this case, the width of the clicker 6 is less than the depth of the receiving groove 3. In order to ensure the stable propagation of sound, the receiving groove 3 penetrates through the side wall of the housing 1. Reducing the width of the clicker 6 can enhance the protection of the clicker 6 and prevent hard objects from contacting the clicker 6 and causing it to produce sound that may mislead people. Several connecting pieces 12 for fixing the housing 1 are fixedly connected to the top of the back of the housing 1. The connecting pieces 12 have fixing holes, which allow screws to pass through the fixing holes to fix the housing 1 to the wall. The thickness of the connecting pieces 12 is the same as the thickness of the pointer 2 and the maximum diameter of the telescopic rod 4, so that the pointer 2 and the telescopic rod 4 can abut against the wall, ensuring that the housing 1 can always remain horizontal when fixed.

[0021] Working principle: When no fire occurs, the limiting plate 5 provides support for the indicator 2. At this time, the telescopic rod 4 is in a retracted state, and the locking piece 8 in the sliding groove 11 provides support for the hammer rod 7, thus keeping the elastic element in a compressed state. When a fire occurs, the limiting plate 5 softens due to high temperature, thus losing its support effect on the indicator 2. At this time, the indicator 2 will move downward under its own weight, thereby pulling the telescopic rod 4 and stretching it to its longest state. Therefore, even when the smoke submerges the housing 1, the indicator 2 can still guide people. During the downward movement of the indicator 2, the pulling rope 9 applies a pulling force to the locking piece 8, pulling it out of the sliding groove 11, allowing the hammer rod 7 to fall downward and strike the clicker 6, making the clicker 6 make a sound, thus alerting people.

All technical solutions falling within the scope of this utility model's concept are protected.
