[0002] A building-type civil defense alarm terminal is a device specifically designed to play a vital role in building environments. It is a crucial terminal link in the urban civil defense alarm system, primarily responsible for the timely and accurate transmission of alarm information to people within the building in emergency situations, such as air raids or major natural disasters.

[0003] The internal components of civil defense alarm notification terminals are quite delicate, requiring regular inspection and replacement in special circumstances. However, existing civil defense alarm notification terminals are generally directly fixed to the wall, making disassembly and replacement inconvenient. Furthermore, in the event of a disaster or other emergency, ensuring personal safety is paramount, and these directly wall-mounted terminals are directly subjected to the force transmitted from the wall during vibrations, potentially damaging these precision instruments. To address this technical problem, this application proposes a building-type civil defense alarm notification terminal. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of existing technologies by proposing a building-type civil defense alarm terminal. The internal shock-absorbing component uses the coordinated action of springs and cylinders, with the cylinders dynamically adjusting the buffering force to achieve all-round shock absorption within a plane. At the same time, the fixing component uses a worm gear transmission structure to control the knob, achieving a precise and firm fixed connection between the terminal and the back plate. It also has the advantages of simple operation and no need for professional tools for installation, which significantly improves construction efficiency while ensuring that it maintains a stable working state in complex environments.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A building-type civil defense alarm terminal includes an alarm device, a triangular lock, and an outer frame. The triangular lock is located on the front of the alarm device, the alarm device is located on the inner side of the outer frame, a fixing component is located on the rear of the alarm device, an inner frame is fixedly connected to the rear of the outer frame, a shock-absorbing component is located on the front of the inner frame, and a back plate is located on the front of the inner frame through the shock-absorbing component.

[0007] Furthermore, the shock-absorbing component includes a second connecting plate fixedly connected to the front side of the inner frame, a push plate fixedly connected to the rear side of the second connecting plate, a second spring provided on the rear side of the push plate, an outer shell sleeved on the outer wall of the push plate, a first connecting plate fixedly connected to the rear side of the outer shell, a cylinder provided inside the upper side of the outer shell, a first spring provided on the upper side of the cylinder, the first spring provided on the lower side of the push plate, and a connecting shaft fixedly connected to the upper side of the push plate, the connecting shaft being slidably connected inside the outer shell.

[0008] Furthermore, the fixing assembly includes a knob rotatably connected to the front side of the back plate, a worm gear fixedly connected to the rear side of the knob, a worm wheel meshing with the lower side of the worm gear, a rotating shaft fixedly connected to the left side of the worm wheel, a bevel gear one fixedly connected to the rear side of the rotating shaft, a bevel gear two meshing with the lower side of the bevel gear, a stud fixedly connected to the lower side of the bevel gear two, and a fixing plate threadedly connected to the upper side of the stud.

[0009] Furthermore, a connecting rod is fixedly connected to the upper side of the connecting shaft, and a torsion spring is provided on the upper side of the connecting rod.

[0010] Furthermore, a rotating block is rotatably connected to the upper side of the connecting rod, and a nut is provided on the upper side of the rotating block. The nut is located on the right side of the inner frame.

[0011] Furthermore, a fixing block is fixedly connected to the rear side of the alarm device, and a slot is provided on the front side of the back plate.

[0024] 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.

[0025] Reference Figure 1 An embodiment of this utility model provides a building-type civil defense alarm notification terminal, including an alarm device 1, a triangular lock 24 and an outer frame 2. The triangular lock 24 is located on the front side of the alarm device 1, the alarm device 1 is located on the inner side of the outer frame 2, a fixing component is located on the rear side of the alarm device 1, an inner frame 7 is fixedly connected to the rear side of the outer frame 2, a shock-absorbing component is located on the front side of the inner frame 7, and a back plate 3 is located on the front side of the inner frame 7 through the shock-absorbing component.

[0026] Specifically, during installation, the outer shell 10 and internal parts can be assembled, the back plate 3 can be fixed to the connecting plate 11, and the nuts 8 can be used to fix the outer shell 10 and the inner frame 7 together. The entire inner frame 7 is embedded in the wall, leaving the knob 4 exposed. There is a ring of iron sheet on the front of the inner frame 7, which can reduce the entry of sand and dust and does not affect the use of the device. The outer frame 2 is fixedly connected to the front of the inner frame 7. There is a movable door on the front of the outer frame 2, which is hollow inside and fixed by the front triangular lock 24 to prevent others from opening it at will and to reduce the entry of foreign objects. The alarm device 1 is hung on the front of the back plate 3, and the knob 4 can be turned to fix the alarm device 1.

[0027] Reference Figure 3 and Figure 4 The shock-absorbing assembly includes a second connecting plate 17 fixedly connected to the front side of the inner frame 7. A push plate 16 is fixedly connected to the rear side of the second connecting plate 17. A second spring 18 is provided on the rear side of the push plate 16. A housing 10 is fitted onto the outer wall of the push plate 16. A first connecting plate 11 is fixedly connected to the rear side of the housing 10. A cylinder 15 is provided inside the upper side of the housing 10. A first spring 14 is provided on the upper side of the cylinder 15. The first spring 14 is located on the lower side of the push plate 16. A connecting shaft is fixedly connected to the upper side of the push plate 16 and is slidably connected inside the housing 10. A connecting rod 12 is fixedly connected to the upper side of the connecting shaft. A torsion spring 25 is provided on the upper side of the connecting rod 12. A rotating block 13 is rotatably connected to the upper side of the connecting rod 12. A nut 8 is provided on the upper side of the rotating block 13 and is located on the right side of the inner frame 7.

[0028] Specifically, when the inner frame 7 shakes, it provides a lateral force to the device. When the connecting rod 12 moves to the left, it compresses spring 14 and pushes the push plate 16 to compress the air in cylinder 15. Spring 14 and cylinder 15 then provide opposing forces, which not only weakens the force transmission but also resets the device when the vibration ends. The connecting plate 17 is fixed inside the inner frame 7. Because this component is installed on both sides, it is not completely fixed, leaving space for buffering. Similarly, when force is transmitted in the forward and backward directions, the push plate 16 compresses spring 18. At the connection between the outer shell 10 and the inner frame 7, there is a connecting rod 12 and a rotating block 13. A torsion spring 25 is installed at the connection. Spring 18 plays a major role in slowing down the force transmission, while torsion spring 25 plays an auxiliary role in helping the device reset. The rotating part ensures that the device can shake slightly, reducing the direct effect of building sway and achieving a force-dissipating effect. It also facilitates the installation of the device. The forward and backward and lateral directions of the device work together to greatly mitigate the impact of natural disasters.

[0029] Reference Figure 2 , Figure 5 and Figure 6The fixing assembly includes a knob 4 rotatably connected to the front side of the back plate 3. A worm gear 9 is fixedly connected to the rear side of the knob 4. A worm wheel 21 is meshed with the lower side of the worm gear 9. A rotating shaft is fixedly connected to the left side of the worm wheel 21. A bevel gear 19 is fixedly connected to the rear side of the rotating shaft. A bevel gear 20 is meshed with the lower side of the bevel gear 19. A stud 22 is fixedly connected to the lower side of the bevel gear 20. A fixing plate 23 is threadedly connected to the upper side of the stud 22. A fixing block 5 is fixedly connected to the rear side of the alarm device 1. A slot 6 is opened on the front side of the back plate 3. A bearing is provided on the front side of the worm gear 9.

[0030] Specifically, turning knob 4 will drive the worm gear 9 behind it. The rotation of worm gear 9 will drive the rotation of worm wheel 21. The rotation of worm wheel 21 will drive the rotation of bevel gear 19. The rotation of bevel gear 19 will drive the rotation of bevel gear 20. Because stud 22 is fixedly connected to bevel gear 20, stud 22 will also rotate. Fixing plate 23 is threadedly connected to the two studs 22, so fixing plate 23 will move downward. The concave design of fixing plate 23 can better engage fixing block 5, thereby fixing the bearings at the front and rear of worm gear 9 of alarm device 1, reducing the resistance caused by rotation and facilitating rotation. In addition, worm wheel 21 and worm gear 9 have self-locking properties and will not rotate arbitrarily. Furthermore, some rubber pads are installed at the upper and lower ends of fixing plate 23, which can play a limiting and buffering role.

[0031] Working Principle: When the terminal encounters vibrations such as earthquakes, the lateral vibration will push the inner frame 7 to displace, causing the connecting rod 12 to move and compress the spring 14. Simultaneously, the push plate 16 pushes the air in the cylinder 15, absorbing the vibration energy through the elastic deformation of the spring. The damping force is adjusted by the gas buffer in the cylinder 15. Together, they generate reverse resistance, slowing the transmission of vibration to the interior of the terminal. When the vibration comes from the front-to-back direction, the push plate 16 compresses the spring 18 as the primary buffer, while the torsion spring 25 at the connection between the outer shell 10 and the inner frame 7 assists in resetting. The movable connection between the rotating block 13 and the connecting rod 12 allows the device to sway slightly to relieve force. When the knob 4 is rotated horizontally, the worm gear 9 rotates synchronously and drives the worm wheel 21 to rotate, causing the coaxial bevel gear 19 to mesh with the bevel gear 20. This causes the stud 22, which is fixedly connected to the bevel gear 20, to rotate, thereby pushing the fixed plate 23, which is threadedly connected to the stud 22, to move downwards. The concave structure of the fixed plate 23 precisely engages with the fixed block 5 of the alarm device 1, achieving a secure connection between the terminal and the back plate 3. The bearings at both ends of the worm 9 reduce rotational resistance, and the self-locking characteristic of the worm wheel 21 and worm 9 prevents the knob 4 from rotating accidentally, ensuring a stable fixed state. The rubber pads at the upper and lower ends of the fixing plate 23 provide limiting buffers during fixing, avoiding damage to components caused by hard contact, and taking into account both ease of installation and connection reliability.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
