Description

Technical Field

[0001] The utility model relates to the technical field of noise detection equipment, in particular to a noise detection equipment which is easy to carry. Background Art

[0002] With the acceleration of industrialization and the increasing severity of urban noise pollution, noise detection has become increasingly important. Existing noise detectors lack protective structures, and their test ends are very susceptible to collisions by external factors during carrying or when not in use, causing the noise detectors to have inaccurate measurements or be damaged, making them inconvenient to carry.

[0003] In order to address the above problems, a Chinese patent with the existing announcement number CN219694356U proposes a portable noise detector, which facilitates the extension of the detector body for detection and retraction for protection through a telescopic component. When retracting into the shell, the arc-shaped groove of the bayonet clamps the shift block, and cooperates with the spring at the bottom to fix the detector in the shell. The anti-collision strip in the shell, the anti-collision cotton on the second cover plate and the spring at the bottom for the extension and retraction of the detector provide comprehensive protection for the detector body, making it safer to carry.

[0004] However, although the above-mentioned portable noise detector can control the contraction of the detector body through the telescopic component, and then comprehensively protect the detector body through anti-collision strips, anti-collision cotton and springs, thereby making it safer to carry, when the portable noise detector protects the detector body through multiple anti-collision strips, due to the irregular shape of the detector body, the protection range of the anti-collision strips on the detector body is limited, resulting in the problem of reduced protection effect on the detector body. Therefore, the utility model provides a noise detection device that is easy to carry to meet the needs. Utility Model Content

[0034] like Figures 1 to 5 As shown, an embodiment of the utility model provides a noise detection device that is easy to carry, including a cylinder 1, which defines a cavity 10 inside, the cylinder 1 has an opening connected to the cavity 10, and a sealing cover 2 is detachably connected to the opening of the cylinder 1. A pressure plate 17 is movably provided in the cavity 10, and a device body 8 is provided on the pressure plate 17. A movable rod 18 is provided at one end of the pressure plate 17 away from the device body 8. A compressed air bag 15 is provided in the cylinder 1, and one end of the movable rod 18 away from the pressure plate 17 contacts with the compressed air bag 15. A protective air bag 13 is arranged on the inner wall of the cylinder 1 around the device body 8. The protective air bag 13 has a fitting surface similar to the outer wall of the device body 8 when inflated, and the protective air bag 13 is connected to the compressed air bag 15 through a pipe 14.

[0035] Specifically, when the device body 8 is moved toward the cavity 10, the device body 8 pushes the pressure plate 17 to move toward the inside of the cavity 10, and the pressure plate 17 applies pressure to the compressed airbag 15 through the movable rod 18, so that the compressed airbag 15 is compressed and the gas is discharged into the protective airbag 13, so that the protective airbag 13 changes from a compressed state to an expanded state, and then the cylinder 1 is sealed with the sealing cover 2. At this time, all-round protection of the device body 8 can be achieved. The overall structure is simple to operate, which improves the protection effect of the device body 8, and solves the problem that when the existing noise detection equipment uses multiple anti-collision strips to protect the detector body, due to the irregular shape of the detector body, the protection range of the anti-collision strips on the detector body is limited, resulting in reduced protection effect on the detector body.

[0036] It should be noted that the protective airbag 13 is fixed to the inner wall of the cylinder 1. When the protective airbag 13 is inflated, there is a gap between the protective airbag 13 and the device body 8 to ensure that the device body 8 can be taken out along the cavity 10. At the same time, the end of the device body 8 close to the opening is the detection end, and the other end is a cylindrical structure. When the device body 8 is taken out along the cavity 10, the device body 8 will squeeze the protective airbag 13, so that the air in the protective airbag 13 flows back into the compressed airbag 15, thereby realizing gas circulation; further, an operating port (not shown in the figure) is inserted into the cylinder 1 to realize the control of the device body 8. For details, please refer to the patent document with announcement number CN219694356U.

[0037] like Figure 4 As shown, in the present embodiment, a movable plate 16 is fixedly connected between the movable rod 18 and the compression airbag 15, a movable groove 20 for the movable plate 16 to move is provided in the cylinder 1, the compression airbag 15 is located in the movable groove 20, a spring 19 is sleeved on the movable rod 18, the spring 19 is located in the cavity 10, the pipe 14 is connected with the end of the protective airbag 13 close to the opening of the cylinder 1, specifically, when the pressure plate 17 moves toward the movable groove 20, the pressure plate 17 will squeeze the spring 19, so that when the sealing cover 2 is opened, the equipment body 8 can automatically slide out along the cavity 10 under the elastic force of the spring 19, and at the same time, the provision of the movable plate 16 can increase the contact area between the movable rod 18 and the compression airbag 15.

[0038] like Figures 2 to 4 As shown, in the present embodiment, a resistance tube 7 which can be in contact with the device body 8 is fixedly connected to the sealing cover 2, and the resistance tube 7 is a hollow structure with openings at both ends. The resistance tube 7 can be sleeved on the detection end of the device body 8, and a sponge 12 is fixedly connected inside the resistance tube 7. An embedding ring 11 is fixedly connected to the sealing cover 2, and the embedding ring 11 is sleeved on the resistance tube 7. The embedding ring 11 can be embedded in the cavity 10 and fit with the inner wall of the cylinder 1. Specifically, when the sealing cover 2 seals the cylinder 1, the resistance tube 7 is sleeved on the detection end of the device body 8. When the sealing cover 2 moves toward the cylinder 1, the resistance tube 7 pushes the device body 8 to move into the cavity 10. At the same time, the embedding ring 11 is embedded in the cavity 10 and fits with the inner wall of the cylinder 1, and the sponge 12 can be in contact with the detection end of the device body 8, so as to avoid damage to the device body 8, improve the protection effect on the device body 8, and facilitate its later carrying.

[0039] like Figures 3 to 5As shown, in this embodiment, the sealing cover 2 is provided with a limiting hole 6, and the cylinder 1 is provided with a limiting assembly 9 for limiting the limiting hole 6. The limiting assembly 9 includes a support plate 91, which is fixedly connected to the cylinder 1, a control rod 92, which is rotatably connected to the support plate 91 through a rotating shaft 95, and a limiting block 93 for limiting the limiting hole 6 is fixedly connected to the control rod 92, and a torsion spring 94 is sleeved on the rotating shaft 95. The two ends of the torsion spring 94 are fixedly connected to the support plate 91 and the control rod 92 respectively. The control rod 92 includes a control end 921 and a connecting end 922, and the connecting end 922 is fixedly connected to the limiting block 93, and the control end 921 is inclined outward. It is fixedly connected to one end of the connection end 922 away from the limit block 93. Specifically, when the sealing cover 2 is fitted with the opening of the cylinder 1, the sealing cover 2 pushes the limit block 93 and the control rod 92 to rotate outward. When the limit block 93 is aligned with the limit hole 6, the limit block 93 limits the limit hole 6 under the action of the torsion spring 94, thereby realizing the limitation of the sealing cover 2 and the cylinder 1. When the sealing cover 2 needs to be opened, it is only necessary to press and hold the control end 921 and move it toward the cylinder 1 so that the limit block 93 is disengaged from the limit hole 6, thereby realizing automatic limitation of the sealing cover 2, improving the disassembly and assembly efficiency of the cylinder 1 and the sealing cover 2, and facilitating the carrying of the equipment body 8.

[0040] like Figure 1 and Figure 2 As shown, in this embodiment, it also includes a shoulder strap 5, both ends of which are fixedly connected to the top of the cylinder 1, and a handle 3 is fixedly connected to the bottom of the cylinder 1. The handle 3 is provided with anti-slip grooves 4. Specifically, the shoulder strap 5 facilitates the carrying of the cylinder 1 of the device body 8, and the handle 3 facilitates the user to use the device body 8.

[0041] Working principle:

[0042] When the device body 8 is moved into the cavity 10, the abutment tube 7 is sleeved on the detection end of the device body 8. When the sealing cover 2 moves toward the cylinder 1, the abutment tube 7 pushes the device body 8 to move into the cavity 10, so that the device body 8 pushes the abutment plate 17 to move into the cavity 10. The abutment plate 17 applies pressure to the compressed airbag 15 through the movable rod 18 and the movable plate 16, so that the compressed airbag 15 is compressed and the gas is discharged into the protective airbag 13, so that the protective airbag 13 changes from a compressed state to an expanded state, thereby protecting the device body 8. When the sealing cover 2 fits with the opening of the cylinder 1, the limit assembly 9 The sealing cover 2 is limited; when the device body 8 is moved out of the cavity 10, it is only necessary to release the limit on the sealing cover 2 through the limit assembly 9. At this time, the device body 8 is pushed to move outside the cylinder 1 under the elastic force of the spring 19, so that the gas in the protective airbag 13 flows back to the compression airbag 15. The overall structure is simple to operate, which improves the protection effect of the device body 8 and solves the problem that when the existing noise detection equipment uses multiple anti-collision strips to protect the detector body, the irregular shape of the detector body limits the protection range of the anti-collision strips on the detector body, resulting in reduced protection effect on the detector body.
