This design reduces the protection of the display screen, making it easy for it to be scratched or even damaged when the user holds the noise detector and it collides with other objects. This affects the normal use of the noise detector and makes it less practical overall. Summary of the Invention

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figure 1-5 As shown, this utility model is an environmental noise detection device, including a detector body 1, and further including: a detection probe 2 fixedly mounted on the top of the detector body 1, a protective cover 3 distributed at the front end of the detector body 1, and an anti-slip grip pad 4 fixedly mounted on the outer side wall of the protective cover 3, a guide block 5 fixedly mounted on the inner side wall of the protective cover 3, and a positioning rod 6 penetrating through the inner side of the guide block 5, the guide block 5 being symmetrically distributed along the vertical center line of the protective cover 3, and the outer diameter of the guide block 5 being adapted to the inner diameter of the guide groove 9, a first auxiliary sliding plate 7 sleeved on the outer side of one end of the positioning rod 6, and a first spring 8 fixedly connected to the surface of one end of the first auxiliary sliding plate 7, the two ends of the first spring 8 being fixedly connected to the surface of one end of the first auxiliary sliding plate 7 and the inner side wall of the guide block 5, respectively, a guide groove 9 being opened on the side wall of the detector body 1, and a positioning hole 10 communicating with one side of the guide groove 9, the positioning hole 10 being symmetrically distributed along the vertical center line of the detector body 1, and the inner diameter of the positioning hole 10 being adapted to the outer diameter of the positioning rod 6, and a support structure being fixedly installed on the back of the detector body 1;

[0025] During operation, when the protective cover 3 is needed to protect the display screen on the surface of the detector body 1, the positioning rod 6 is first pulled laterally. At this time, the lateral movement of the positioning rod 6 causes the first auxiliary sliding plate 7 to move laterally as well, improving the stability of the positioning rod 6 during the lateral movement. At the same time, the lateral movement of the positioning rod 6 will cause the first spring 8 to deform and generate a reverse force. Therefore, when the positioning rod 6 moves to one side of the positioning hole 10, the lateral pulling force applied to the positioning rod 6 is released. At this time, the reverse force generated by the deformation of the first spring 8 will cause the positioning rod 6 to move laterally as well, thereby inserting one end of the positioning rod 6 into the inside of the positioning hole 10, thereby achieving the positioning treatment of the guide block 5. This allows the protective cover 3 to cover the surface of the detector body 1 in all directions, effectively protecting the surface of the detector body 1 and preventing scratches caused by bumps during subsequent use.

[0026] The support structure includes a fixed base 11, a rotating rod 12, a locking hole 13, and a support rod 14. The fixed base 11 is fixedly installed on the back of the main body 1 of the detector, and the bottom of the fixed base 11 is connected to the rotating rod 12. The rotating rod 12 is rotatably connected to the fixed base 11 through a bearing seat. The rotating rod 12 is symmetrically distributed along the vertical center line of the fixed base 11. The side wall of the rotating rod 12 is provided with a locking hole 13. The locking holes 13 are equidistantly distributed on the side wall of the rotating rod 12, and the inner diameter of the locking hole 13 is adapted to the outer diameter of the locking rod 16. The bottom of the rotating rod 12 is provided with a support rod 14.

[0027] When it is necessary to use the support rod 14 to support and limit the main body 1 of the detector during operation, first rotate the rotating rod 12 so that it rotates along the fixed base 11, and then pull the support rod 14 so that the support rod 14 slides along the side wall of the rotating rod 12, which facilitates subsequent adjustment of the position of the support rod 14 and makes it easier to support and limit the main body 1 of the detector.

[0028] A second spring 15 is fixedly connected to the inner side of one end of the support rod 14, and a locking rod 16 is fixedly connected to the other end of the second spring 15. The two ends of the second spring 15 are respectively fixedly connected to the inner side wall of the support rod 14 and the inner side of one end of the locking rod 16. The outer diameter of the locking rod 16 is matched with the inner diameter of the lock hole 13, and the locking rod 16 is symmetrically distributed along the vertical center line of the support rod 14. A second auxiliary sliding plate 17 is sleeved on the outer side of one end of the locking rod 16.

[0029] During operation, when the support rod 14 is needed to support the entire detector body 1, the support rod 14 is pulled, causing it to slide along the rotating rod 12. When the support rod 14 slides to the appropriate position, the locking rod 16 is moved to one side of the lock hole 13. At this time, the lateral force applied to the locking rod 16 disappears. Since the locking rod 16 will compress the second spring 15 during lateral movement, causing it to deform, the reverse force generated by the deformation of the second spring 15 can be used to achieve the lateral reset of the locking rod 16. Then, one end of the locking rod 16 is inserted into the inside of the lock hole 13, thereby achieving the positioning of the support rod 14. This facilitates the subsequent use of the support rod 14 to better support the detector body 1. The second auxiliary sliding plate 17 is used to improve the stability of the locking rod 16 during lateral movement.

[0030] The positioning rod 6 is slidably connected to the guide block 5 through the first auxiliary slide plate 7, and the outer diameter of the positioning rod 6 is adapted to the inner diameter of the positioning hole 10;

[0031] When the positioning rod 6 is subjected to a lateral force, it will drive the first auxiliary slide plate 7 to move laterally. At this time, the setting of the first auxiliary slide plate 7 can improve the stability of the positioning rod 6 during the lateral movement.

[0032] Positioning holes 10 are symmetrically distributed on both sides of the main body 1 of the detector, and the positioning holes 10 and the main body 1 of the detector form an integrated structure;

[0033] During operation, the positioning holes 10 are symmetrically distributed on both sides of the main body 1 of the detector, and the inner diameter of the positioning holes 10 is matched with the outer diameter of the positioning rod 6. Therefore, when one end of the positioning rod 6 is inserted into the inner side of the positioning hole 10, it is convenient to use the engagement of the positioning rod 6 and the positioning hole 10 to achieve the positioning of the protective cover 3.

[0034] The lock holes 13 are evenly distributed along the side wall of the rotating rod 12, and the inner diameter of the lock holes 13 is adapted to the outer diameter of the lock rod 16;

[0035] During operation, since the size of the lock hole 13 is compatible with the size of the lock rod 16, when one end of the lock rod 16 is inserted into the inside of the lock hole 13, it is convenient to achieve a stable connection between the support rod 14 and the rotating rod 12, so that the support rod 14 can be used to support the entire detector body 1.

[0036] Working principle: When the protective cover 3 is needed to protect the display screen on the surface of the detector body 1, the positioning rod 6 is pulled laterally. This lateral movement of the positioning rod 6 causes the first spring 8 to deform via the first auxiliary slide plate 7, generating a reverse force. Then, when the positioning rod 6 moves to one side of the positioning hole 10, the lateral pulling force applied to the positioning rod 6 is released. The reverse force generated by the deformation of the first spring 8 then causes the positioning rod 6 to move laterally, thus inserting one end of the positioning rod 6 into the inside of the positioning hole 10. This achieves the positioning of the guide block 5, allowing the protective cover 3 to fully cover the surface of the detector body 1, thereby protecting the surface of the detector body 1. To provide effective protection and prevent scratches on the surface of the main body 1 of the detector from impacts during subsequent use, when the support rod 14 is needed to support and limit the main body 1 of the detector, the rotating rod 12 is rotated to rotate along the fixed base 11, and then the support rod 14 is pulled, and the support rod 14 slides along the rotating rod 12. When the support rod 14 slides to the appropriate position, the locking rod 16 is moved to one side of the lock hole 13. At this time, the reverse force generated by the deformation of the second spring 15 is used to input one end of the locking rod 16 into the inside of the lock hole 13, thereby realizing the positioning of the support rod 14 and facilitating better support of the main body 1 of the detector using the support rod 14 in the future.

[0037] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
