Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] This utility model provides a technical solution: a handheld acoustic imaging device. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 The system includes an outer ring 1 and an inner ring 3. The inner ring 3 is located inside the outer ring 1. An annular groove 101 is formed on the inner wall of the outer ring 1. A handle 2 is installed on the outer wall of the outer ring 1. A ball bearing 4 is installed on the outer wall of the inner ring 3. A counterweight plate 5 is installed on the inner side of the inner ring 3. An acoustic imaging device 14 is mounted on the upper side of the counterweight plate 5. The acoustic imaging device 14 contains a main control circuit board. The acoustic imaging device 14 is a common and publicly disclosed mature technology product in the prior art. Its main control circuit board includes a main... The system includes components such as a control chip, power module, communication module, signal processing module, control module, and storage module. A first clamping plate 6 is provided on the rear side of the counterweight plate 5, and a second clamping plate 9 is provided on the front side of the counterweight plate 5. A screw 7 is installed on the front side of the first clamping plate 6, and limit rods 8 are installed on both sides of the screw 7. A through hole 10 is opened in the middle of the second clamping plate 9, and a limit ring 11 is installed on the front side of the through hole 10. A threaded sleeve 13 is rotatably engaged on the limit ring 11, and limit holes 12 are provided on both sides of the through hole 10.
[0021] Please see Figure 1 , Figure 2 , Figure 3The screw 7 passes through the counterweight plate 5 and then slides into the through hole 10. The screw 7 also passes through the through hole 10 and then threadedly engages with the threaded sleeve 13. The limiting rod 8 passes through the counterweight plate 5 and then slides into the limiting hole 12. The front side of the first clamping plate 6 and the rear side of the second clamping plate 9 are in contact with the acoustic imaging device 14. Therefore, rotating the threaded sleeve 13 causes the second clamping plate 9 to contract towards the first clamping plate 6, thereby clamping and fixing the acoustic imaging device 14. The ball bearing 4 is movably engaged with the annular groove 101, and the ball bearing 4 is also engaged with the outer ring... The inner ring 3 is engaged by the annular groove 101 on the inner side, allowing the inner ring 3 to rotate within the outer ring 1. Since the acoustic imaging device 14 is fixed in the lower half of the inner ring 3, the center of the inner ring 3 always faces downward. Under the action of the ball bearing 4, the inner ring 3 and the acoustic imaging device 14 will always be in a parallel state, avoiding the acoustic imaging device from tilting when held. There are two handles 2, which are symmetrically arranged, allowing for two-handed holding and reducing hand fatigue caused by single-handed use.
[0022] The handheld acoustic imaging device in this utility model consists of an outer ring 1, an inner ring 3, and an acoustic imaging device 14. Handles 2 are installed on both sides of the outer ring 1 for handheld use. An annular groove 101 is formed on the inner wall of the outer ring 1, and the inner ring 3 is located inside the outer ring 1. A ball bearing 4 is installed on the outer wall of the inner ring 3, and the ball bearing 4 engages with the annular groove 101 inside the outer ring 1, so that the inner ring 3 can rotate inside the outer ring 1.
[0023] A counterweight plate 5 is installed at the bottom of the inner ring 3, and a first clamping plate 6 is provided on the rear side of the counterweight plate 5. A second clamping plate 9 is provided on the front side of the counterweight plate 5. A screw 7 is installed on the front side of the first clamping plate 6, and limit rods 8 are provided on both sides of the screw 7. The limit rods 8 are also fixedly connected to the first clamping plate 6. A through hole 10 is opened in the middle of the second clamping plate 9, and limit holes 12 are also opened on both sides of the through hole 10. A limit ring 11 is installed on the front side of the through hole 10, and a threaded sleeve 13 is rotatably sleeved on the limit ring 11. The screw 7 on the first clamping plate 6 is an internally threaded rod. After the screw 7 and the limit rod 8 pass through the counterweight plate 5, they are inserted into the through hole 10 and the limit hole 12 on the second clamping plate 9. After the screw 7 passes through the through hole 10, it is threadedly connected to the threaded sleeve 13.
[0024] When in use, the acoustic imaging device 14 is placed on the counterweight plate 5. Rotating the threaded sleeve 13 causes the second clamping plate 9 to retract toward the first clamping plate 6, thereby clamping and fixing the acoustic imaging device 14. Since the acoustic imaging device 14 is fixed in the lower half of the inner ring 3, the center of the inner ring 3 always faces downward. Under the action of the ball bearing 4, the inner ring 3 and the acoustic imaging device 14 will always be in a parallel state, avoiding the acoustic imaging device from tilting when held, which could lead to measurement inaccuracies when the acoustic imaging device shakes. Furthermore, the outer ring 1 can be held with both hands, reducing hand fatigue caused by single-handed operation.
