[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a height-adjustable bracket for an environmental noise detection device, comprising a support platform 1, a plurality of sleeve rods 2 are rotatably connected to the outside of the support platform 1, a fixed block 4 is fixedly connected to the other end of the sleeve rod 2, a limiting groove 5 is provided inside the fixed block 4, a spring 6 is fixedly connected to the inside of the limiting groove 5, a limiting block 7 is fixedly connected to the other end of the spring 6, a pull rod 8 is fixedly connected to one side of the limiting block 7, a clamping block 9 is fixedly connected to the other side of the limiting block 7, a sliding rod 3 is slidably connected to the inside of the sleeve rod 2, a plurality of positioning holes 10 are provided on the outside of the sliding rod 3, a clamping assembly is provided on the top of the support platform 1, the outside of the limiting block 7 is slidably connected to the inside of the limiting groove 5, the spring 6 is sleeved on the outside of the pull rod 8, and the other end of the clamping block 9 passes through the inner wall of the sleeve rod 2 and is engaged with the inside of the positioning hole 10.

[0024] Specifically, the support platform 1 is connected with a plurality of sleeve rods 2, and the slide rod 3 is fixed inside the sleeve rod 2 by a snap-fitting manner, so that the support platform 1 can be supported. At the same time, a foot is fixed to the bottom end of the slide rod 3, so that the bracket can remain stable when placed on the ground and will not shake during detection. By pulling the pull rod 8, the movement of the pull rod 8 drives the limit block 7 to move, so that the limit block 7 slides inside the limit groove 5 and compresses the spring 6. The movement of the limit block 7 can be limited by the limit groove 5, so that the limit block 7 will drive the card block when it moves. 9 moves, so that the block 9 is disengaged from the positioning hole 10, and then the slide bar 3 is pulled outward to adjust the length of the leg of the bracket, thereby realizing the height adjustment of the bracket, so that the noise detection equipment can detect environmental noise at different heights, thereby improving the accuracy of detection and the flexibility of use of the bracket. The spring 6 pull rod 8 will return to its original state after being released, and the elastic force is released to push the limit block 7 to move, so that the block 9 enters the interior of one of the positioning holes 10, thereby fixing the slide bar 3. Multiple positioning holes 10 can meet the needs of users to adjust to different heights, thereby improving the flexibility of use.

[0025] Reference Figure 3 The clamping assembly includes a support block 15, which is fixedly connected to the top of the support platform 1. The top of the support platform 1 is rotatably connected to a rotating shaft 16, the outside of the rotating shaft 16 is fixedly connected to a worm gear 17, the top of the rotating shaft 16 is fixedly connected to a rotating rod 18, both ends of the rotating rod 18 are rotatably connected to a moving rod 19, the other end of the moving rod 19 is rotatably connected to a slider 20, the top of the slider 20 is fixedly connected to a clamping plate 21, and the upper inner part of the support block 15 is fixedly connected to a guide rod 22, and the outer part of the guide rod 22 is slidably connected to the inner parts of the two sliders 20.

[0026] Specifically, the support table 1 plays a role of fixed support for the support block 15, so that the support block 15 can fix the noise detection equipment through the clamping assembly, and the rotation of the worm gear 17 causes the rotating shaft 16 to rotate, thereby driving the rotating rod 18 to rotate inside the support block 15. At this time, the moving rods 19 connected at both ends of the rotating rod 18 will move accordingly, thereby pulling the slider 20 to slide along the guide rod 22 through the other end of the moving rod 19, wherein the guide rod 22 can play a role of limiting and guiding, so that the slider 20 maintains horizontal and linear movement, and drives the clamping plate 21 to move, so that the two clamping plates 21 are close to each other to achieve clamping and fixing of the noise detection equipment, which can maintain the stability of the detection equipment, thereby improving the accuracy of the detection result, and at the same time, different detection equipment can be fixed, thereby improving the adaptability of the bracket.

[0027] Reference Figure 1The bottom of the support platform 1 is rotatably connected to a screw rod 11, the external thread of the screw rod 11 is connected to a threaded sleeve 12, the external rotatable connection of the threaded sleeve 12 is connected to multiple connecting rods 13, the bottom end of the screw rod 11 is fixedly connected to a handle 14, and the other ends of the multiple connecting rods 13 are respectively rotatably connected to the external parts of multiple sleeve rods 2.

[0028] Specifically, the screw rod 11 can be driven to rotate by rotating the handle 14, so that the threaded sleeve 12 can move under the limit of multiple connecting rods 13. While moving, the threaded sleeve 12 will move through one end of the connecting rod 13, so that the other end of the connecting rod 13 pulls the sleeve rod 2 toward the center, so that the multiple legs of the bracket can be retracted to reduce the occupied space when not in use, and the stability of the bracket can be improved when the legs are spread out.

[0029] Reference Figure 4 A worm 23 is rotatably connected to the top of the support platform 1 near the worm wheel 17 , one end of the worm 23 is fixedly connected to a knob 24 , and the outer side of the worm 23 is meshedly connected to the outer side of the worm wheel 17 .

[0030] Specifically, the worm 23 can be rotated by turning the knob 24. When the worm 23 rotates, it drives the worm wheel 17 to rotate, thereby causing the worm wheel 17 to rotate, so that the clamping assembly is operated through the rotating shaft 16, thereby clamping and fixing the noise detection equipment, and improving the stability of the equipment during use.

[0031] Working principle: When using this bracket, the bracket can be placed on the ground, and the noise detection equipment can be placed above the support block 15. Then, the worm 23 can be rotated by turning the knob 24, thereby rotating the worm gear 17. The worm gear 17 can drive the rotating shaft 16 to rotate, thereby rotating the rotating rod 18, which can drive the moving rod 19 connected at both ends to move. The moving rod 19 can drive the slider 20 to slide along the guide rod 22. At the same time, the slider 20 can drive the splint 21 to move, so that the two splints 21 are close to each other, thereby clamping and fixing the environmental noise detection equipment, so that the detection equipment can remain stable during the raising process of the bracket, avoiding errors caused by shaking. Then, by pulling the external pull rod 8 of the fixed block 4 on one of the sleeve rods 2, the movement of the pull rod 8 drives the limit block 7 to move, so that the limit block 7 slides inside the limit groove 5, compressing the spring 6, and at the same time, the limit block 7 drives the block 9 to move, so that the block 9 is separated from the positioning hole 10, and then the slide bar 3 is pulled outward, and the pull rod 8 is released after adjusting to a suitable position, so that the spring 6 returns to its original state and pushes the limit block 7 to move, and then the block 9 enters the inside of one of the positioning holes 10, thereby fixing the slide bar 3, repeating the above operation to adjust the other sleeve rods 2, realizing the height adjustment of the bracket, so that the noise detection device can detect environmental noise at different heights, improving the accuracy of the detection and the flexibility of the bracket. At the same time, by rotating the handle 14 to drive the screw rod 11 to rotate, the threaded sleeve 12 can be moved, and then the sleeve rod 2 is driven to approach the center through the other end of the threaded sleeve 12, so that the multiple legs of the bracket can be retracted, thereby reducing the occupied space when not in use, and improving the stability of the bracket when the legs are open.
