[0002] An alarm is a safety device used to issue an alarm when a safety event occurs. Alarms can be divided into various types according to different purposes and occasions, such as anti-theft alarms, smoke alarms, dangerous gas alarms, etc. They use different technical means to detect different safety risks and issue different alarm signals.

[0003] Among them, the dangerous gas alarm is used to detect whether there is dangerous gas in the surrounding air and issue an alarm when the safety threshold is exceeded. In the related art, the dangerous gas alarm mainly consists of a shell, a sensor module and an alarm mechanism. The sensor module can detect the concentration of flammable gas in the air and control the alarm mechanism to alarm; the shell is wrapped outside the sensor module and the alarm mechanism to protect the sensor module and the alarm mechanism. The dangerous gas alarm is generally stored in a high place, and when the alarm encounters an external force, it is easy to fall, thereby causing the sensor module to be damaged due to falling.

[0012] Through the above technical scheme, the driving motor is started, so that the driving motor drives the driving rod to rotate and the transmission rod drives the hydraulic piston to slide, thereby realizing the sealed sliding connection of the hydraulic piston and the hydraulic tank.

[0013] Optionally, two hydraulic pistons are arranged, and the two hydraulic pistons are arranged on the two sides of the communication part between the hydraulic tank and the bag, and the two hydraulic pistons are connected by a connecting rod, one end of the connecting rod is slidably connected with one of the hydraulic pistons, and the other end of the connecting rod is slidably connected with the other hydraulic piston.

[0014] Through the above technical scheme, the arrangement of the two hydraulic pistons accelerates the discharge of the liquid in the hydraulic tank, thereby achieving the purpose of quickly adjusting the gravity center position of the alarm.

[0015] Optionally, a liquid storage bag is further arranged in the shell, the liquid storage bag is in communication with the hydraulic tank and the bag through a communication pipe, and an adjusting assembly for adjusting the flow in the communication pipe is arranged on the shell.

[0016] Through the above technical scheme, the arrangement of the liquid storage bag on one hand makes the liquid pressure in the bag not easy to be too large, and on the other hand makes the liquid flow into the liquid storage bag, so that the gravity center of the alarm is quickly offset upward, thereby preventing the alarm from bouncing up and then falling.

[0017] Optionally, the adjusting assembly comprises two adjusting plates and an adjusting spring, the two adjusting plates are arranged on the two sides of the communication pipe and are rotatably connected to the side walls of the shell on the corresponding side, the two adjusting plates are connected by the spring, under the elastic force of the spring, the two adjusting plates clamp the communication pipe, the included angle of the two adjusting plates is arranged, and the included angle of the two adjusting plates which are in contact with the communication pipe between the liquid storage bag and the hydraulic tank is arranged towards the hydraulic tank, so that the liquid in the liquid storage bag flows into the hydraulic tank in one direction, and the included angle of the two adjusting plates which are in contact with the communication pipe between the liquid storage bag and the bag is arranged towards the liquid storage bag, so that the liquid in the bag flows into the liquid storage bag in one direction.

[0023] In summary, the present application has at least the following beneficial technical effects:

[0024] 1. When the acceleration sensor senses that the acceleration of the alarm is 9.8 m / s 2 , the control driving assembly is controlled, so that the driving assembly drives the hydraulic piston to slide, so that the liquid pressure in the hydraulic tank is increased and quickly filled into the bag, thereby adjusting the gravity of the alarm, and the side of the alarm with the bag preferentially contacts the ground, at this time, the shock-absorbing spring acts on the sensor module, so that the sensor module is not easy to be damaged, and the gravity adjusting mechanism is arranged to allow the staff to purposefully perform shock-absorbing treatment on the local sensor module, thereby saving the shock-absorbing cost of the alarm;

Detailed Implementation

[0030] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0031] This application discloses an alarm device with earthquake and drop resistance functions.

[0032] Reference Figure 1 The alarm includes a housing 100, a sensor module 200 disposed inside the housing 100, an acceleration sensor 300 disposed on the housing 100 for detecting the acceleration of the alarm, a center of gravity adjustment mechanism 400 for adjusting the center of gravity of the alarm, and a shock absorption mechanism 500 for damping the sensor module 200.

[0033] When the accelerometer 300 detects that the alarm is falling, the center of gravity adjustment mechanism 400 operates to adjust the alarm's center of gravity to the side of the shock absorption mechanism 500, thus making the alarm less likely to be damaged when it falls. At the same time, the center of gravity adjustment mechanism 400 ensures that the alarm falls from the same position, making it easier for staff to provide targeted protection at the fall location, thereby reducing the number of shock absorption mechanisms 500 and production costs.

[0034] The gravity center adjusting mechanism 400 comprises a bag 410, a hydraulic tank 420 and hydraulic pistons 430. The bag 410 is located on one side of the sensor module 200, and one side of the bag 410 is fixedly connected with the sensor module 200, and the other side is fixedly connected with the side wall of the shell 100. The hydraulic tank 420 is located on the side of the sensor module 200 close to the bottom surface of the shell 100, and the hydraulic tank 420 is fixedly connected with the bottom surface of the shell 100. A buffer rubber pad is arranged between the hydraulic tank 420 and the sensor module 200, and the buffer rubber pad is fixedly connected with the hydraulic tank 420. The hydraulic tank 420 and the bag 410 are communicated through a connecting pipe, and the connecting pipe is a hose. The hydraulic tank 420 contains a liquid, which can be water.

[0035] With reference to Figure 1 and Figure 2 The hydraulic pistons 430 are provided in two, and the two hydraulic pistons 430 are arranged on the two sides of the connecting pipe communicated with the hydraulic tank 420. The two hydraulic pistons 430 are sealingly and slidably connected with the hydraulic tank 420 in the direction of approaching or moving away from each other, and the two hydraulic pistons 430 are connected through a connecting rod 432. The two hydraulic pistons 430 are each provided with a sliding groove 431, and the sliding direction of the sliding groove 431 is perpendicular to the sliding direction of the two hydraulic pistons 430. The connecting rod 432 is rotatably connected with the bottom wall of the shell 100, and the connecting rod 432 is located between the two hydraulic pistons 430. The connecting rod 432 is hingedly connected with sliding blocks 433 at both ends, and the sliding blocks 433 are slidably connected with the sliding grooves 431 on the corresponding sides.

[0036] When one hydraulic piston 430 slides, the connecting rod 432 is synchronously driven to rotate, so that the other hydraulic piston 430 is synchronously slid, that is, the two hydraulic pistons 430 are synchronously moved in the direction of approaching or moving away from each other.

[0037] One of the hydraulic pistons 430 is connected with a driving assembly 600 for driving the hydraulic piston 430 to slide. The driving assembly 600 comprises a driving motor 610, a driving rod 620 and a transmission rod 630. The driving motor 610 is electrically connected with the acceleration sensor 300. The body of the driving motor 610 is fixedly connected with the bottom wall of the shell 100. The output shaft of the driving motor 610 is fixedly connected with one end of the driving rod 620. The other end of the driving rod 620 is rotatably connected with one end of the transmission rod 630. The other end of the transmission rod 630 is rotatably connected with the hydraulic piston 430. The rotation axes of the driving rod 620 and the transmission rod 630, and the rotation axis of the transmission rod 630 and the hydraulic piston 430 are all perpendicular to the length of the driving rod 620.

[0038] The driving motor 610 is started, so that the driving motor 610 drives the driving rod 620 to rotate, and drives the transmission rod 630 to slide the hydraulic piston 430 connected with the transmission rod 630, and drives the other hydraulic piston 430 to slide.

[0039] With reference toFigure 1 And Figure 3 In order to reduce the shaking of the sensor module 200, a liquid storage bag 700 is arranged in the shell 100, and the liquid storage bag 700 is arranged on the side of the sensor module 200 away from the bag 410, and the liquid storage bag 700 is arranged close to the bottom wall of the shell 100. The liquid storage bag 700 and the hydraulic tank 420 and the bag 410 are communicated through the communication pipe 720, and the communication pipe 720 is a flexible pipe. The shell 100 is provided with an adjusting assembly 800 for adjusting the flow in the communication pipe 720.

[0040] The adjusting assembly 800 includes two adjusting plates 810 and an adjusting spring 820, and the two adjusting plates 810 are arranged on both sides of the communication pipe 720, and one adjusting plate 810 is rotatably connected to the top wall of the shell 100, and the other adjusting plate 810 is rotatably connected to the bottom wall of the shell 100. The free ends of the two adjusting plates 810 are inclined to extend towards the communication pipe 720, so that the two adjusting plates 810 are arranged at an angle and clamp the communication pipe 720. The two adjusting plates 810 are connected by the adjusting spring 820, so that the two adjusting plates 810 clamp the communication pipe 720 under the elastic force of the adjusting spring 820. In order to prevent the communication pipe 720 from being removed from between the two adjusting plates 810, the adjusting spring 820 is provided with two adjusting springs 820, which are arranged on both sides of the communication pipe 720, and the two adjusting springs 820 are fixedly connected to one adjusting plate 810 at one end and fixedly connected to the other adjusting plate 810 at the other end.

[0041] The end of the two adjusting plates 810 is provided as an inclined surface, so that when the adjusting plate 810 clamps the communication pipe 720, the adjusting plate 810 and the communication pipe 720 are in surface contact, thereby improving the resistance stability of the adjusting plate 810 and the communication pipe 720.

[0042] In order to make the liquid in the liquid storage bag 700 flow only in one direction into the hydraulic tank 420, the angle between the two adjusting plates 810 of the adjusting assembly 800 on the communication pipe 720 between the liquid storage bag 700 and the hydraulic tank 420 is arranged towards the hydraulic tank 420. In order to make the liquid in the bag 410 flow only in one direction into the liquid storage bag 700, the angle between the two adjusting plates 810 of the adjusting assembly 800 on the communication pipe 720 between the bag 410 and the liquid storage bag 700 is arranged towards the liquid storage bag 700.

[0043] When the alarm falls to the ground, the sensor module 200 presses down the bag 410, and when the pressure in the bag 410 reaches a certain degree, the sensor module 200 continues to press down the bag 410, on the one hand, the pressure in the bag 410 continues to increase, affecting the service life of the bag 410, on the other hand, the sensor module 200 hits the bag 410, and the impact force of the sensor module 200 itself is still large, and the arrangement of the liquid storage bag 700 and the adjusting assembly 800 makes the pressure in the bag 410 increase to a certain degree, and the liquid storage bag 700 releases pressure once, prolongs the moving distance of the sensor module 200, and reduces the sensor module 200 again, so that the sensor module 200 falls in the same deceleration mode, and the sensor module 200 is not easy to be damaged due to the rebound force being too large, and in addition, the arrangement of the liquid storage bag 700 makes the center of gravity of the alarm deviate immediately after the alarm falls to the ground, so that the alarm is not easy to bounce up, and the alarm is not easy to be damaged again.

[0044] The damping mechanism 500 includes a plurality of damping springs 510, one end of the damping spring 510 is connected with the liquid storage bag 700, the other end is fixedly connected with the sensor module 200, and the damping spring 510 is located on the side of the sensor module 200 away from the bag 410.

[0045] Since the liquid storage bag 700 is soft, in order to improve the connection stability of the damping spring 510 and the liquid storage bag 700, the connecting plate 710 is fixedly connected on the liquid storage bag 700, and the plurality of damping springs 510 are fixedly connected with the connecting plate 710.

[0046] In order to prevent the sensor module 200 from shaking left and right, the telescopic rod 730 is arranged on the sensor module 200, one end of the telescopic rod 730 is fixedly connected with the sensor module 200, and the other end is fixedly connected with the connecting plate 710.

[0047] In order to prevent the liquid storage bag 700 from moving and causing the communication pipe 720 between the liquid storage bag 700 and the hydraulic tank 420 to curl and affect the backflow of the liquid in the communication pipe 720, the two adjusting plates 810 of the adjusting assembly 800 between the liquid storage bag 700 and the hydraulic tank 420 are rotationally connected with the connecting plate 710.

[0048] The implementation principle of the embodiment of the application is that when the alarm falls, the acceleration sensor 300 monitors that the acceleration of the alarm is 9.8 m / s 2 When the acceleration of the alarm is 9.8 m / s , the driving motor 610 starts to drive the driving rod 620 to rotate, and the transmission rod 630 pushes the hydraulic piston 430 to extrude the liquid in the hydraulic tank 420 into the bag 410, so as to realize damping of the sensor module 200.

[0049] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
