AI Technical Summary
When using existing acoustic equipment, the LCD screen is prone to self-rotation due to prolonged exposure, causing test interruptions.
The LCD screen module is connected to the base by rotation. The combination of square rods, square tubes, sliding plates and locking rods, combined with wedge grooves and spring design, achieves stable fixation of the LCD screen and prevents it from rotating on its own.
This effectively prevents the device from closing due to the LCD screen's rotation during long-term use, ensuring the continuity and stability of the test.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.
[0021] Reference Figures 1-3 An acoustic detector includes a base 1, on which an LCD screen module 2 is rotatably connected. Two symmetrical clearance grooves 3 are formed on the upper surface of the base 1. A rotating column 7 is rotatably connected within the clearance grooves 3. A square tube 4 is welded to the outer circumference of the rotating column 7. Two symmetrical fixing blocks 6 are bolted to one side of the LCD screen module 2. A square rod 5 is rotatably connected to one side of the fixing blocks 6. Multiple grooves 9 are formed on the square rod 5, which slides within the square tube 4. A square groove 8 is formed on one side of the square tube 4, and the square groove 8 is connected to the square tube 4. The internal connection is made of two symmetrical sliding plates 11 in the square groove 8. The upper surface of the sliding plate 11 is fixedly connected to a block 12 by bolts. A locking rod 13 is rotatably connected between the two blocks 12, and the locking rod 13 is embedded in one of the grooves 9. With the provided square rod 5 and square tube 4, after the device is unfolded, the locking rod 13 is embedded in one of the grooves 9 to fix the square rod 5 and square tube 4, thereby fixing the LCD screen module 2 and preventing it from rotating and causing the device to close during long-term use.
[0022] In this invention, two fixing plates 14 are bolted to the inner walls of both sides of the square groove 8. Slide rods 10 are bolted to the lower surfaces of the fixing plates 14, with the other end of each slide rod 10 fixed to the bottom inner wall of the square groove 8. All slide rods 10 pass through and slidably connect to the sliding plate 11. The slide rods 10 guide the sliding plate 11 as it moves up and down along the square groove 8, preventing it from tilting and causing the locking rod 13 to fail to stably embed into the corresponding groove 9. Springs 15 are welded to the lower surfaces of multiple fixing plates 14. The other end of each spring 15 is fixed to the upper surface of the slide plate 11. Each spring 15 is sleeved on the outside of the slide rod 10. The inner wall of one side of the groove 9 is a wedge-shaped structure. The multiple grooves 9 are spaced at the same interval. Corner guards 16 are provided at the four corners of the base 1 and the four corners of the LCD module 2. A handle 17 is provided on one side of the base 1. The handle 17 is made of rubber. Multiple sets of heat dissipation holes are opened on both sides of the housing of the base 1. The multiple sets of heat dissipation holes on the same side are spaced apart.
[0023] The use of this utility model involves the following steps:
[0024] S1: When the LCD module 2 is unfolded, the square rod 5 slides along the inner wall of the square tube 4, and the wedge structure on the groove 9 squeezes the clamping rod 13 to move along the square groove 8. After the unfolding is completed, the clamping rod 13 is embedded in one of the grooves 9, so that the square rod 5 cannot move in the opposite direction in the square tube 4, thereby fixing the LCD module 2.
[0025] S2: When adjustment is needed, move the slide plate 11 upwards to completely disengage the lever 13 from the groove 9, then move the square rod 5 along the inner wall of the square tube 4 to adjust the unfolding angle of the LCD module 2.
[0026] Furthermore, the terms "installation," "setup," "connection," and "socketing" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections via an intermediate medium, or internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
