[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-Figure 3 As shown, a multifunctional sound level meter with a portable structure includes a sound level meter body 1, a test microphone 11 is fixedly connected to the top of the sound level meter body 1, a mounting groove 12 is provided at the rear end of the sound level meter body 1, a protective mechanism 2 is plugged into the outer wall of the sound level meter body 1, a dustproof mechanism 3 is plugged into the rear of the sound level meter body 1, the protective mechanism 2 includes a protective block 21, the outer wall of the protective block 21 is plugged into the outer wall of the sound level meter body 1, a semicircular groove is provided on the outer wall of the protective block 21, and the dustproof mechanism 3 includes a dustproof net 31, and the outer wall of the dustproof net 31 is plugged into the rear of the sound level meter body 1.

[0025] The sound level meter body 1 is protected by the protection mechanism 2 to reduce damage to the sound level meter body 1 when it falls. The dustproof net 31 can be replaced or cleaned later by quickly disassembling the dustproof mechanism 3.

[0026] like Figure 2 , Figure 3 As shown, one end of the protective block 21 is fixedly connected to a protective strip 22, the outer wall of the protective strip 22 is slidably connected to the outer wall of the sound level meter body 1, the bottom end of the protective block 21 is fixedly connected to a U-shaped buffer block 23, the inner wall of the U-shaped buffer block 23 is movably connected to the bottom of the sound level meter body 1, and the bottom end of the U-shaped buffer block 23 is fixedly connected to a lifting ring 24.

[0027] When the sound level meter body 1 falls and hits the ground, because the protective block 21, the protective strip 22 and the U-shaped buffer block 23 are located outside the sound level meter body 1, when the sound level meter body 1 falls, it is highly likely that the protective block 21, the protective strip 22 and the U-shaped buffer block 23 will first contact the ground, thereby avoiding direct contact between the sound level meter body 1 and the ground as much as possible, reducing damage to the sound level meter body 1, and achieving a protective effect.

[0028] like Figure 3 , Figure 4 As shown, the bottom end of the inner cavity of the U-shaped buffer block 23 is fixedly connected with four positioning blocks 25 in a rectangular array, the outer wall of the positioning block 25 is plugged into the bottom of the sound level meter body 1, the top of the protective block 21 is slidably connected with a limiting plate 26, the outer wall of the limiting plate 26 is plugged with a fixing plate 29, the bottom end of the fixing plate 29 is fixedly connected to the top of the protective block 21, the outer wall of the limiting plate 26 is plugged into the inner wall of the sound level meter body 1, one end of the limiting plate 26 is fixedly connected with a spring 28, and one end of the spring 28 is fixedly connected to one end of the fixing plate 29.

[0029] When it is necessary to maintain the sound level meter body 1 or replace the protective device of the outer wall of the sound level meter body 1, pull the limit plate 26, and at the same time, the limit plate 26 drives the spring 28 to extend, so that the outer wall of the limit plate 26 is no longer plugged into the inner wall of the sound level meter body 1, and then the lifting ring 24 can be pulled downward to drive the U-shaped buffer block 23 and the protective block 21 to move downward synchronously, so that the positioning block 25 is no longer plugged into the inner wall of the sound level meter body 1, thereby separating the sound level meter body 1 from the protective mechanism 2, and then the sound level meter body 1 can be maintained or the protective mechanism 2 can be replaced, which makes it easy to disassemble.

[0030] like Figure 3 , Figure 4 As shown, a guide block 27 is fixedly connected to the bottom end of the limiting plate 26 , and an outer wall of the guide block 27 is slidably connected to the top of the protection block 21 , and the guide block 27 has a T-shaped appearance.

[0031] When the limiting plate 26 moves, it drives the guide block 27 to slide on the inner wall of the protection block 21, and the limiting plate 26 is limited by the guide block 27 to prevent the limiting plate 26 from falling off.

[0032] like Figure 2 , Figure 5 As shown, the rear end of the dustproof net 31 is fixedly connected to a toggle block 32, the outer wall of the protective block 21 is fixedly connected to three connecting blocks 33 in a circular array, the rear end of the connecting block 33 is fixedly connected to an elastic block 34, the outer wall of the connecting block 33 is slidably connected to the inner wall of the mounting groove 12, the outer wall of the elastic block 34 is plugged into the inner wall of the sound level meter body 1, and the elastic block 34 has a semi-spherical shape.

[0033] When the sound level meter body 1 is working, the heat dissipation effect of the heat dissipation port is reduced due to excessive dust on the dustproof net 31. The toggle block 32 can be rotated, and the toggle block 32 drives the dustproof net 31 to rotate synchronously. The dustproof net 31 drives the connecting block 33 to rotate synchronously on the inner wall of the sound level meter body 1. The connecting block 33 drives the elastic block 34 to rotate synchronously, so that the elastic block 34 is deformed, and the outer wall of the elastic block 34 is no longer plugged into the inner wall of the sound level meter body 1. When the toggle block 32 can no longer rotate, the dustproof net 31 can be taken out and cleaned, which has the effect of quick disassembly.

[0034] The working principle of the utility model is as follows: when in use, the staff can pick up the sound level meter body 1 and carry it by holding the protective block 21 with their fingers, and at the same time, the rope can be passed through the hanging ring 24, and the rope and the hanging ring 24 are tied together, thereby preventing the sound level meter body 1 from being lost. The sound level meter body 1 can also be carried in this way, which has the effect of being easy to carry. When the sound level meter body 1 falls and falls on the ground, because the protective block 21, the protective strip 22 and the U-shaped buffer block 23 are located outside the sound level meter body 1, when the sound level meter body 1 falls, the protective block 21, the protective strip 22 and the U-shaped buffer block 23 are located outside the sound level meter body 1. When the body 1 falls, the protection block 21, the protection strip 22 and the U-shaped buffer block 23 are most likely to contact the ground first, thereby avoiding direct contact between the sound level meter body 1 and the ground as much as possible, reducing the damage to the sound level meter body 1, and achieving a protective effect. Later, when the sound level meter body 1 needs to be maintained or the protective device on the outer wall of the sound level meter body 1 needs to be replaced, the limit plate 26 is pulled to make the limit plate 26 drive the guide block 27 to slide on the inner wall of the protection block 21, and the guide block 27 limits the limit plate 26 to prevent the limit plate 26 from falling off. When the limit plate 26 drives the spring 28 to extend, the outer wall of the limit plate 26 is no longer plugged into the inner wall of the sound level meter body 1, and then the lifting ring 24 can be pulled downward to drive the U-shaped buffer block 23 and the protective block 21 to move downward synchronously, so that the positioning block 25 is no longer plugged into the inner wall of the sound level meter body 1, thereby separating the sound level meter body 1 from the protective mechanism 2, and then the sound level meter body 1 can be maintained or the protective mechanism 2 can be replaced, which has the effect of facilitating disassembly. Later, if the sound level meter body 1 is working, the dust on the dustproof net 31 is too To prevent the heat dissipation effect of the heat dissipation port from being reduced, the toggle block 32 can be rotated, and the toggle block 32 drives the dustproof net 31 to rotate synchronously, and the dustproof net 31 drives the connecting block 33 to rotate synchronously on the inner wall of the sound level meter body 1, and the connecting block 33 drives the elastic block 34 to rotate synchronously, so that the elastic block 34 is deformed, and the outer wall of the elastic block 34 is no longer plugged into the inner wall of the sound level meter body 1. When the toggle block 32 can no longer rotate, the dustproof net 31 can be taken out and cleaned, which has the effect of quick disassembly, thereby greatly improving the user experience.
