Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and in particular to a fire protection equipment for fire protection engineering. Background Technology

[0002] Fire protection engineering involves a wide variety of fire protection devices, which together constitute a complete fire protection system to ensure the safety of buildings and people. These devices include, but are not limited to, fire detectors, alarm buttons, smoke detectors, water pump connections, sprinkler heads, and other facilities. In addition, there are other fire protection devices such as fire elevators, fire telephones, and fire broadcasts. Together, they form a complete fire protection system that provides strong protection for the fire safety of buildings.

[0003] However, with the increasing use of fire and electricity in modern households, the frequency of household fires is also rising. Once a household fire occurs, it can easily lead to serious consequences due to delayed detection, directly causing significant loss of life and property. Therefore, exploring the characteristics of household fires and fire prevention strategies is of practical significance for reducing fire losses. Fire alarms are fire-fighting devices used in fire protection engineering, which can promptly alert people in the event of a fire, ensuring their safety. However, traditional fire alarms are usually fixed at a high place with screws. Repairing the alarm typically requires ladders or other climbing tools. Because screws cannot be quickly removed and installed, repair personnel spend more time at height, increasing safety hazards and making disassembly and repair inconvenient, thus presenting certain limitations. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art where traditional fire alarms are usually fixed at a high place with screws. When repairing the alarm, ladders or other climbing tools are usually used. Since the screws cannot be quickly removed and installed, the maintenance personnel will stay at a high place for a long time, which will increase the safety hazards and make disassembly and maintenance inconvenient. Therefore, a fire protection device for fire protection engineering is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fire-fighting device for fire protection engineering, comprising a base and a smoke detector, wherein the smoke detector is snapped onto one side of the base, and two insert rods are fixedly installed on both sides of the middle of one end of the smoke detector, each insert rod having a notch in the middle of one end, and a limiting groove on one side of each insert rod; slots are provided on both sides of the middle of one end of the base, and movable grooves are provided in the middle of both sides of the base, the slots communicating with the movable grooves; a pressing rod is slidably snapped onto the middle of the movable groove, and a limiting block is fixedly installed on the outer side of the middle of the pressing rod, the limiting block being slidably snapped onto the middle of the notch; a limiting rod is fixedly installed on one end of the limiting block, the limiting rod being inserted into the limiting groove; a spring is fixedly installed on one end of the pressing rod, and the spring is fixedly connected to one end of the movable groove.

[0006] Preferably, a sliding groove is provided above and below the center of the notch, and a sliding strip is fixedly installed above and below the center of the limiting block, with the sliding strip and the sliding groove being slidably engaged.

[0007] Preferably, a displacement groove is provided above the middle of the other end of each of the two movable grooves, and multiple limiting plates are uniformly fixedly installed above the middle of the pressing rod, with the limiting plates abutting against the two sides of the displacement groove.

[0008] Preferably, a cover plate is fixedly installed at the middle of the other end of the smoke alarm, and a smoke inlet hole is provided between the cover plate and the smoke alarm.

[0009] Preferably, an indicator light is fixedly installed on one side of the cover plate, and horn holes are opened on both sides of the middle of the other end of the smoke alarm.

[0010] Preferably, a fixing block is fixedly installed at both the upper and lower ends of the base, and an anti-corrosion layer is pasted on the other end of the base.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, when disassembling the smoke alarm for maintenance, simply press the two pressing rods inward to compress the spring. The limiting block and the limiting rod will also move and disengage from the notch and the groove. After the limiting is removed, the alarm can be removed for maintenance. During installation, align the insertion rod with the slot and insert it. Because the limiting block prevents the insertion rod from reaching the bottom, press the pressing rod to compress the spring, causing the limiting block to tilt to one side. After the insertion rod reaches the bottom, release the pressing rod. The spring will return to its original position, allowing the limiting block and the limiting rod to engage with the groove and the limiting slot respectively, thus completing the installation. By simplifying the disassembly and installation process, the time maintenance personnel spend at heights is reduced, improving safety.

[0013] 2. In this utility model, when the pressing rod is pressed, the limiting plate will abut against one side of the displacement groove to limit the movement. The limiting can remind the maintenance personnel of the progress of installation and disassembly. When the pressing rod cannot be stopped, it means that the limiting of the smoke alarm has been canceled. At this time, the smoke alarm can be removed for maintenance.

[0014] 2. In this utility model, by setting an anti-corrosion layer on one side of the base, the anti-corrosion layer is in direct contact with the wall surface, which can reduce the occurrence of corrosion of the base due to water seepage from the wall surface, thus giving the device a longer service life.

Detailed Implementation

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figure 1-5 As shown, this utility model provides a fire protection device for fire protection engineering, including a base 1 and a smoke alarm 2. The smoke alarm 2 is snapped onto one side of the base 1. Insert rods 21 are fixedly installed on both sides of the middle of one end of the smoke alarm 2. A notch 22 is opened in the middle of one end of each insert rod 21. A limiting groove 23 is opened on one side of each insert rod 21. Slots 13 are opened on both sides of the middle of one end of the base 1. Movable grooves 14 are opened in the middle of both sides of the base 1. The slots 13 and movable grooves 14 are connected. A pressing rod 15 is slidably snapped onto the middle of the movable groove 14. A limiting block 16 is fixedly installed on the outer side of the middle of the pressing rod 15. The limiting block 16 is slidably snapped onto the middle of the notch 22. A limiting rod 17 is fixedly installed on one end of the limiting block 16. The limiting rod 17 is inserted into the limiting groove 23. A spring 18 is fixedly installed on one end of the pressing rod 15. The spring 18 is fixedly connected to one end of the movable groove 14.

[0024] The specific settings and functions of this embodiment are described in detail below. When disassembling the smoke alarm 2 for maintenance, simply press the two pressing rods 15 inwards. At this time, the spring 18 will contract, and the limiting block 16 and limiting rod 17 at the end of the pressing rod 15 will also move in the direction of the spring 18's contraction. During this process, the limiting block 16 and limiting rod 17 will disengage from the notch 22 and the slide groove 24, thereby canceling the limitation on the smoke alarm 2. At this time, the operator can remove the smoke alarm 2 for maintenance. During installation, the two insert rods 2 of the smoke alarm 2 are... Align the rod with slot 13 and insert it. At this time, due to the presence of the limiting block 16, the insertion rod 21 cannot reach the bottom. The operator only needs to press the pressing rod 15 to drive the spring 18 to retract, so that the limiting block 16 is biased to one side. At this time, the insertion rod 21 can reach the bottom. Then release the pressing spring 18 on the pressing rod 15, which will drive the pressing rod 15 to reset, so that the limiting block 16 and the limiting rod 17 are respectively engaged in the slide groove 24 and the limiting groove 23, thereby completing the installation. By simplifying the disassembly process, the time that maintenance personnel spend at height is shortened, thereby improving safety and having greater practicality.

[0025] Example 2, as Figure 1 , Figure 2 and Figure 3As shown, grooves 24 are provided above and below the middle of the notch 22. Slide strips 161 are fixedly installed above and below the middle of the limiting block 16. The slide strips 161 and the grooves 24 are slidably engaged. Displacement grooves 19 are provided above the middle of the other end of the two movable grooves 14. Multiple limiting plates 20 are evenly fixedly installed above the middle of the pressing rod 15. The limiting plates 20 abut against the two sides of the displacement grooves 19. A cover plate 26 is fixedly installed in the middle of the other end of the smoke alarm 2. A smoke inlet hole 28 is provided between the cover plate 26 and the smoke alarm 2. An indicator light 27 is fixedly installed on one side of the cover plate 26. Horn holes 25 are provided on both sides of the middle of the other end of the smoke alarm 2. Fixing blocks 12 are fixedly installed at the upper and lower ends of the base 1. An anti-corrosion layer 11 is pasted on the other end of the base 1.

[0026] The overall effect of this embodiment is that, in the event of a fire, smoke will enter the smoke alarm 2 through the smoke inlet 28. At this time, the horn hole 25 will emit an alarm sound, and the indicator light 27 will flash to alert the residents. When disassembling the smoke alarm 2 for maintenance, simply press the two pressing rods 15 inward. At this time, the spring 18 will retract, and the limiting block 16 and limiting rod 17 at the end of the pressing rod 15 will move in the direction of the spring 18's retraction. During this process, the limiting block 16 and limiting rod 17 will disengage from the notch 22 and the slide groove 24, thereby releasing the limitation on the smoke alarm 2. At this time, the operator can remove the smoke alarm 2 for maintenance. During installation, align the two insertion rods 21 of the smoke alarm 2 with the slot 13. Insert the rod 21 into the wall. At this time, due to the presence of the limiting block 16, the insertion rod 21 cannot reach the bottom. The operator only needs to press the pressing rod 15 to cause the spring 18 to contract, so that the limiting block 16 is biased to one side. At this time, the insertion rod 21 can reach the bottom. Then, release the pressing spring 18 on the pressing rod 15, which will cause the pressing rod 15 to return to its original position, so that the limiting block 16 and the limiting rod 17 are respectively engaged in the sliding groove 24 and the limiting groove 23, thereby completing the installation. By simplifying the disassembly process, the time that maintenance personnel spend at high places is shortened, thereby improving safety and making it more practical. In addition, by setting an anti-corrosion layer 11 on one side of the base 1, the anti-corrosion layer 11 is in direct contact with the wall surface, which can reduce the occurrence of corrosion of the base 1 due to water seepage from the wall surface, so that the device has a longer service life.

[0027] The operating method and working principle of this device are as follows: When a fire occurs, smoke will enter the smoke detector 2 through the smoke inlet 28. At this time, the horn hole 25 will emit an alarm sound, and the indicator light 27 will flash to alert the residents. When disassembling the smoke detector 2 for maintenance, simply press the two pressing rods 15 inward. At this time, the spring 18 will retract, and the limiting block 16 and limiting rod 17 at the end of the pressing rod 15 will move in the direction of the spring 18's retraction. During this process, the limiting block 16 and limiting rod 17 will disengage from the notch 22 and the slide groove 24, thereby releasing the limiting effect on the smoke detector 2. At this time, the operator can... The smoke detector 2 can then be removed for inspection. During installation, align the two rods 21 of the smoke detector 2 with the slots 13 and insert them. At this time, due to the presence of the limiting block 16, the rods 21 cannot reach the bottom. The operator only needs to press the pressing rod 15 to cause the spring 18 to retract, causing the limiting block 16 to deflect to one side. At this time, the rods 21 can reach the bottom. Then, release the pressing spring 18 on the pressing rod 15, which will cause the pressing rod 15 to return to its original position, so that the limiting block 16 and the limiting rod 17 are respectively engaged in the slide groove 24 and the limiting groove 23, thus completing the installation. By simplifying the disassembly and installation process, the time that maintenance personnel spend at heights is reduced, thereby improving safety.
