[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figure 3-Figure 5 The utility model provides an embodiment: a natural gas alarm device that is easy to install, including a shell 1, the bottom of the shell 1 is connected to a base plate 2 by a snap buckle, and a plurality of card blocks 3 are fixedly connected to the bottom of the base plate 2, and the plurality of card blocks 3 are connected to the fixing base 5 by a snap assembly 4. This connection method makes the installation of the device more convenient, without the need for complex tools and tedious steps. In actual installation scenarios, whether it is self-installation by home users or batch installation in commercial places, it can be completed easily and quickly, greatly saving installation time, effectively reducing installation difficulty, and improving installation efficiency. At the same time, the snap connection between the plurality of card blocks 3 and the fixing base 5 can ensure that the device remains in a stable position after installation The fixing base 5 is provided with a card slot 7 on the top, a slide 2 16 on the left side of the inner wall of the card slot 7, a slide 6 on the right side of the fixing base 5, and an anti-pollution cover 9 is fixedly connected to the front end of the bottom of the fixing base 5. The anti-pollution cover 9 can effectively prevent dust, oil and other impurities from entering the key part of the bottom of the device connected to the fixing base 5, avoiding the accumulation of impurities affecting the normal operation and the possible damage to the device such as corrosion, thereby extending the service life of the device. The top of the inner side of the anti-fouling cover 9 is fixedly connected with a suction cup 15, and the top of the suction cup 15 is rotatably connected with a pressure block 10. Limiting holes 11 are provided on the top of the left and right sides of the pressure block 10, and a mounting hole 12 is provided at the front end of the right side of the fixing seat 5. A spring 13 is provided inside the mounting hole 12, and the spring 13 is connected to the limiting hole 11 through a limiting pin 14. When the device is installed, press the device as a whole on the mounting surface (such as a wall, etc.). As the pressure block 10 rotates, the suction cup 15 connected to the bottom will gradually fit closely with the mounting surface. During the fitting process, the air in the suction cup 15 will be gradually squeezed out, thereby A negative pressure is formed between the surfaces, generating an adsorption force, so that the suction cup 15 can be tightly adsorbed on the installation surface, further enhancing the stability and sealing of the device after installation, and further preventing external dust, moisture, etc. from entering the interior through the gap between the bottom of the device and the installation surface, thereby improving the protection performance of the device. When the device is firmly attracted to the installation surface, the pressure block 10 can be connected and cooperated with the spring 13 set in the installation hole 12 opened at the front end of the right side of the fixing seat 5 through the limiting holes 11 opened at the top of the left and right sides thereof and the limit pin 14. Due to the elastic action of the spring 13, the rotation of the pressure block 10 will be restricted to prevent the suction cup 15 from losing its adsorption force due to accidental touch.

[0031] Reference Figure 1 、 Figure 5 and Figure 6A speaker 22 is provided at the rear end of the top of the shell 1. The speaker 22 can emit a loud and clear alarm in time when an abnormal situation such as excessive natural gas concentration occurs, so that people around can know the dangerous situation in the first time and take corresponding measures, which greatly improves the warning effect of the device and ensures the safety of people and the environment. A card slot 28 is provided on the front side of the fixing seat 5. The inner wall of the card slot 28 fits with the outer side of the pressure block 10. This fitting design enables the pressure block 10 to maintain better stability and position accuracy during rotation and operation, further ensuring the reliability of the suction cup 15 and the installation surface. Adsorption, thereby enhancing the stability of the entire device after installation, a power interface 21 is provided on the front side of the shell 1, and the locking assembly 4 includes a push block 17. The push block 17 is slidably connected to the slide groove 16. The push block 17 can slide smoothly in the slide groove 16, which is convenient for the card block 3 and When the fixing seat 5 performs the locking operation, it performs corresponding auxiliary pushing and other actions to make the locking process smoother and more efficient. The left side of the pushing block 17 is fixedly connected to the limit block 18, and the left side of the limit block 18 is fixedly connected to multiple springs 2 19. The limit block 18 is connected to the slide groove 2 16 through multiple springs 2 19. When the block 3 is locked in the slot 1 7 or moved out of the slot 1 7, the limit block 18 can move back and forth in time through the pushing force of the spring 2 19 by the pushing block 17, playing the role of locking and auxiliary reset. The inner wall of the slot 1 7 is in contact with the outer side of the block 3, and the inner wall of the slot 1 7 is relatively provided with multiple fixing blocks 20. The locking assembly 4 is in contact with the side close to the multiple fixing blocks 20. This close fitting relationship can further ensure the stability of the block 3 in the slot 1 7 and ensure the stability of the device after installation. The shape of the fixing seat 5 is L-shaped and the shape of the limit pin 14 is U-shaped.

[0032] Working principle: First, perform the preliminary assembly of the device, connect the shell 1 to the base plate 2 through the buckle, then align the multiple blocks 3 at the bottom of the base plate 2 with the card slot 7, slide slot 1 6 and slide slot 2 16 on the fixing seat 5, and prepare for the card installation. When the card block 3 is engaged with the fixing seat 5, the push block 17 slides in the slide slot 6 to assist in pushing. At the same time, the limit block 18 applies thrust to the multiple springs 2 19 through the push block 17 and moves back and forth in time, so that the card block 3 smoothly enters the card slot 7 along the slide to complete the engagement. In this process, the locking component 4 is tightly fitted with the multiple fixed blocks 20 on the inner wall of the card slot 7 to ensure stability. After the device is installed, press it as a whole on the installation surface (such as a wall, etc.). At this time, rotate the pressure block 10, and its bottom The suction cup 15 connected to the upper part gradually fits tightly with the installation surface. During the fitting process, the air in the suction cup 15 is gradually squeezed out to form negative pressure to generate adsorption force, so that the suction cup 15 is tightly adsorbed on the installation surface. When the device is firmly adsorbed on the installation surface, the pressure block 10 is connected and matched with the spring 13 and the limit pin 14 in the installation hole 12 opened at the front end of the right side of the fixing seat 5 through the limit holes 11 opened at the top of the left and right sides. Under the elastic action of the spring 13, the rotation of the pressure block 10 is limited to prevent accidental touch from causing the suction cup 15 to lose its adsorption force. When abnormal conditions such as excessive natural gas concentration occur, the speaker 22 at the rear end of the top of the shell 1 will promptly issue a loud and clear alarm sound so that people around can be aware of the dangerous situation and take measures.
