[0020] The present utility model will be further described in detail below with reference to the drawings and through specific embodiments. The following embodiments are only descriptive and do not limit the protection scope of the present utility model.

[0021] Please refer to Figures 1-4, the present utility model provides a technical solution: a noise analyzer for airflow detection with a buffer mechanism, including a rubber sleeve 1. The rubber sleeve 1 can protect the noise analyzer body 2. The noise analyzer body 2 is sleeved inside the rubber sleeve 1, and the noise analyzer body 2 can perform noise analysis. A buffer column 3 is arranged on the front surface of the rubber sleeve 1. The buffer column 3 is used to set corresponding components. A cavity is formed inside the buffer column 3. A fixing plate 4 is fixedly arranged at a position near the middle inside the buffer column 3. The fixing plate 4 is used to fix corresponding components. Silicone guide columns 5 are fixedly arranged on both the front and back surfaces of the fixing plate 4. The silicone guide columns 5 play a supporting role. Link rods 6 are arranged at positions near both the front and back ends inside the buffer column 3. The link rods 6 are used to play a connecting role. Extension rubber balls 7 are arranged on both the front and back surfaces of the buffer column 3. The extension rubber balls 7 can extend outwards to extend the contact distance between the noise analyzer body 2 and the ground. Guide grooves 8 are formed on the opposite sides of the two link rods 6 facing each other. The guide grooves 8 facilitate the movement of the silicone guide columns 5. Buffer springs 9 are fixedly arranged on the opposite sides of the two silicone guide columns 5 facing away from each other. The buffer springs 9 play a role in buffering and energy absorption.

[0022] Furthermore, the number of buffer columns 3 arranged is several, and an equal distance design is adopted between every two buffer columns 3. Among them, the buffer column 3 is used to set corresponding components.

[0023] Furthermore, the rear end of the buffer column 3 penetrates through the rubber sleeve 1 and extends to its outside. The buffer column 3 is fixedly connected with the rubber sleeve 1. Among them, with this design, the buffer column 3 is limited.

[0024] Furthermore, the opposite sides of the two link rods 6 facing away from each other penetrate through the buffer column 3 and extend to its outside. The link rods 6 are movably connected with the buffer column 3. Among them, the link rods 6 are used to play a connecting role.

[0025] Furthermore, the opposite sides of the two extension rubber balls 7 facing away from each other are fixedly connected with the link rods 6. Among them, the extension rubber balls 7 can extend outwards to extend the contact distance between the noise analyzer body 2 and the ground.

[0026] Furthermore, the opposite sides of the two silicone guide columns 5 facing away from each other extend into the inside of the guide grooves 8 and are in contact with the inner walls of the guide grooves 8. The silicone guide columns 5 are movably connected with the guide grooves 8. The guide grooves 8 facilitate the movement of the silicone guide columns 5.

[0027] Furthermore, the opposite sides of the two buffer springs 9 facing away from each other are fixedly connected with the inner walls of the guide grooves 8. Among them, the buffer springs 9 play a role in buffering and energy absorption.

[0028] Working principle: When the device falls and is impacted, the rubber sleeve 1 can protect the noise analyzer body 2 from the top, both sides and the rear end, avoiding direct contact with the ground. Through the extension rubber balls 7 provided, when the front and rear ends are collided, since the extension rubber balls 7 extend out a certain distance, they will first contact the ground, avoiding the contact between the noise analyzer body 2 and the ground, thus playing a role in protecting the noise analyzer body 2. And when the extension rubber balls 7 are subjected to impact force, they will drive the connecting rod 6 provided on the buffer column 3 to move. The movement of the connecting rod 6 will drive the buffer spring 9 and the silica gel guide column 5 to compress and buffer, buffering and absorbing the impact force.

[0029] It can be known from the above working process that:

[0030] This noise analyzer for airflow detection with a buffer mechanism, by setting the rubber sleeve 1, the buffer column 3, the extension rubber balls 7 and the buffer spring 9, makes the device more portable and improves the protection performance during use. It can protect the front end of the device, bringing convenience to the user, improving the practicability of the device, and meeting the user's needs.
