Description

Technical Field

[0001] This utility model relates to the field of thickness gauge technology, specifically a height-adjustable thickness gauge. Background Technology

[0002] An ultrasonic thickness gauge is a type of thickness gauge that measures thickness based on the principle of ultrasonic pulse reflection. When an ultrasonic pulse emitted by the probe passes through the object being measured and reaches the material interface, the pulse is reflected back to the probe. The thickness of the material being measured is determined by accurately measuring the time it takes for the ultrasonic wave to travel through the material.

[0003] Existing ultrasonic thickness gauges are typically used by holding the probe head in one hand and the main body of the ultrasonic thickness gauge in the other. However, the detection distance of the handheld probe head is often limited by the user's range of motion. When ultrasonic detection is required at a high place, it is often difficult to detect quickly, which can easily affect the overall working efficiency of the ultrasonic thickness gauge.

[0004] Chinese patent discloses an adjustable-height ultrasonic thickness gauge (authorization announcement number CN220729191U). This patented technology uses a sliding structure to allow the probe head to move on the wall, making it easier to detect high walls. This significantly improves the overall efficiency of the probe head and solves the problem that the detection range of existing ultrasonic thickness gauges is often limited by the user's range of movement, thereby greatly improving the ease of use of the ultrasonic thickness gauge.

[0005] However, it has certain drawbacks: while it achieves height adjustment through sliding wheels, a suction fan, and an electric push rod, the sliding wheels and mechanical locking device are prone to insufficient friction on vibrating or uneven walls, causing the probe to accidentally shift or fall off. The negative pressure suction of the suction fan fails on rough surfaces due to large gaps, causing the equipment to shake. In summary, its height adjustment requires the coordinated operation of multiple components (such as motor-driven transmission wheels, sliding wheels, and push rod extension and retraction), which is cumbersome. It has poor stability and low efficiency in high-altitude operations, severely limiting its applicability in complex industrial scenarios. Utility Model Content

[0006] The purpose of this invention is to provide a height-adjustable thickness gauge to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A height-adjustable thickness gauge includes a thickness gauge body, a signal line is plugged into the upper end of the thickness gauge body, and a probe is fixedly connected to one end of the signal line;

[0009] The probe is provided with a height adjustment mechanism, which includes a slide tube. A fixing bolt is threaded through the left end of the upper surface of the slide tube, and a sliding plate is slidably connected inside the slide tube. A fixing sleeve is fixed to the left end of the sliding plate, and a fixing bolt is threaded through the left side surface of the fixing sleeve. A pressing mechanism is provided at the right end of the slide tube.

[0010] As a further embodiment of this utility model: the thickness gauge body includes a host, the front surface of the host is provided with a display screen, and the front surface of the host is provided with an operation button located below the display screen.

[0011] As a further embodiment of this utility model: the pressing mechanism includes a C-shaped plate, a pressure plate is slidably connected inside the C-shaped plate, slide rods are movably connected through the four corners of the pressure plate, and multiple springs are fixedly connected to the lower surface of the pressure plate.

[0013] As a further improvement of this utility model, the signal line is plugged into the upper part of the host.

[0014] As a further embodiment of this utility model: the right end of the slide tube is fixed to the left side surface of the pressure plate, and the lower ends of the slide rod and the spring are both fixed to the inner lower surface of the C-shaped plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The sliding locking design of the slide tube and slide plate in this invention supports stepless adjustment of the probe height, allowing for flexible adaptation to different measurement scenarios without the need for tools, significantly expanding the operating range. The spring buffer mechanism in the pressing mechanism not only avoids damage caused by rigid collision between the probe and the measuring surface, but also ensures stable contact during measurement. Combined with the ultrasonic time-difference algorithm, it achieves high-precision detection. In summary, the probe and adjustable height mechanical structure enhance the equipment's adaptability to complex industrial environments such as high temperatures and confined spaces, balancing measurement efficiency and operational safety, and greatly improving its practical value.

[0021] Please see Figure 1 In this embodiment of the present invention, a height-adjustable thickness gauge includes a thickness gauge body 1, the thickness gauge body 1 includes a host 2, a display screen 3 is provided on the front surface of the host 2, and an operation button 4 is provided on the front surface of the host 2 below the display screen 3. A signal line 5 is inserted into the upper end of the thickness gauge body 1, the signal line 5 is inserted into the upper end of the host 2, and a probe 6 is fixedly connected to one end of the signal line 5.

[0022] Display screen 3 is used for real-time visualization of output information, including measurement results, working status, etc.

[0023] Operation button 4 is used to select measurement mode or material calibration, etc.

[0024] Probe 6 is an ultrasonic probe that emits high-frequency sound waves and receives echoes, calculating the thickness of the object based on the time difference.

[0025] exist Figures 1-3 In the middle: The probe 6 is provided with a height adjustment mechanism 7 on the outside. The height adjustment mechanism 7 includes a slide tube 8. The upper surface of the slide tube 8 is threadedly connected to the left end of a fixing bolt 9. The slide tube 8 is slidably connected to a slide plate 10. The lower end of the fixing bolt 9 is attached to the upper surface of the slide plate 10. The left end of the slide plate 10 is fixedly connected to a fixing sleeve 11. The fixing sleeve 11 is movably sleeved on the outside of the probe 6. The left side surface of the fixing sleeve 11 is threadedly connected to a fixing bolt 12. The right end of the fixing bolt 12 is attached to the left side surface of the probe 6. The right end of the slide tube 8 is provided with a pressing mechanism 13. The pressing mechanism 13 includes a C-shaped plate 14. The C-shaped plate 14 is slidably connected to a pressure plate 15. The right end of the slide tube 8 is fixedly connected to the left side surface of the pressure plate 15. The four corners of the pressure plate 15 are movably connected to slide rods 16. The lower surface of the pressure plate 15 is fixedly connected to multiple springs 17. The lower ends of the slide rods 16 and springs 17 are fixedly connected to the lower inner surface of the C-shaped plate 14.

[0026] Figure 1 The probe end of the middle probe 6 is facing downwards;

[0027] The lower surface of the C-shaped plate 14 is attached to the wall. Pressing the pressure plate 15 can drive the probe 6 to move towards the wall through the sliding tube 8, sliding plate 10, and fixing sleeve 11 until it is attached to the wall. This is used to measure the thickness of the wall at a higher position.

[0028] The slide plate 10 slides in the slide tube 8 and is fixed by the fixing bolt 9, which makes it easy to adjust the extension length of the slide plate 10, thereby adjusting the measurement height.

[0029] The working principle of this utility model is as follows: First, a coupling agent is applied to the surface of the probe 6. Then, the lower surface of the C-shaped plate 14 is attached to the wall. The pressure plate 15 is pressed down, and the spring 17 is compressed, causing the slide tube 8 to move the slide plate 10 and the fixing sleeve 11 toward the wall until the detection end of the probe 6 is in close contact with the wall. The probe 6 emits ultrasonic waves and receives the echoes. The host 2 calculates the thickness based on the sound wave time difference, and the result is displayed on the display screen 3. The fixing bolt 9 is loosened, and the slide plate 10 inside the slide tube 8 is slid to adjust the extension length of the probe 6 to adapt to different height requirements. The fixing bolt 9 is then locked to fix the position.
