Description
Technical Field
[0001] This utility model relates to the field of ultrasonic thickness gauge technology, specifically a portable thickness gauge. Background Technology
[0002] An ultrasonic thickness gauge is an instrument used to measure the thickness of materials. It uses ultrasonic technology to achieve non-contact measurement. Its working principle is based on the change in the propagation speed of ultrasonic waves in different materials. When the probe sends a pulse to the surface of the material, the beam passes through the material and is reflected back by the inner wall or bottom surface. The instrument calculates the thickness of the material based on the time of the received reflected signal.
[0003] Because ultrasonic thickness gauges are used in a variety of scenarios, high demands are placed on their portability and reliability. For example, Chinese utility model patent CN219284237U discloses a portable ultrasonic thickness gauge. This portable ultrasonic thickness gauge, through a protective module, uses a rotating protective cover to separate it from the opening of the protective shell. After placing the probe inside the protective shell, pressing the probe inwards and releasing the protective cover allows the cover to return to its original position, sealing the opening of the protective shell. When the probe needs to be removed, rotating the protective cover releases the seal. An elastic element and a movable rod work together to press a movable plate inside the protective shell, pushing the probe outwards for easy removal and providing good protection for the probe. However, this portable ultrasonic thickness gauge lacks a suitable grip structure, making it inconvenient for users to hold and carry, thus compromising its portability.
[0004] Therefore, how to effectively improve the portability of ultrasonic thickness gauges is an urgent problem to be solved in this field. Summary of the Invention
[0005] In view of the problems existing in the ease of use of existing ultrasonic thickness gauges, the purpose of this utility model is to provide a portable thickness gauge that can effectively solve the problems in the prior art.
[0006] To achieve the above objectives, the portable thickness gauge provided by this utility model includes a protective shell, a thickness gauge body, a display, and control buttons. The thickness gauge body is disposed inside the protective shell, and the display and control buttons are disposed on the upper surface of the thickness gauge body. An anti-slip hand strap is disposed on the left side of the protective shell.
[0007] The protective shell includes a shell body, a bottom anti-slip strip, side anti-slip strips, finger pads, a connecting ring, a strap, and a suction cup. The bottom anti-slip strip is provided at the front end of the shell body, the side anti-slip strips are provided on both sides of the shell body, the finger pad is provided at the lower end of the shell body, the connecting ring is fixedly connected to the lower end of the shell body, the strap is fixedly connected to the center of the connecting ring, and the suction cup is fixedly connected to the upper end of the shell body.
[0008] Preferably, the outer shell is fitted onto the outside of the thickness gauge body, and the outer shell is made of nitrile rubber.
[0009] The above technical solution incorporates a shell made of nitrile rubber, which has strong wear resistance, provides protection for the thickness gauge body, and extends the service life of the thickness gauge body.
[0010] Preferably, the lower surface of the finger pad has four arc-shaped grooves, and the strap is disposed below the finger pad.
[0011] The above technical solution incorporates a finger pad with four arc-shaped grooves that match the fingers, conforming to ergonomics. When the user holds the device, the fingers are positioned within the arc-shaped grooves of the finger pad, and the strap contacts the back of the hand, providing good positioning. The protective shell and the thickness gauge body will not slip out of the hand, ensuring good portability.
[0012] Preferably, the suction cups are provided in three identical forms, and the three suction cups are arranged in an equilateral triangle structure.
[0013] With the above technical solution, a suction cup is set up. When thickness measurement is required, the thickness gauge body can be attached to a relatively smooth vertical plane, and the thickness gauge body can be pressed to make the suction cup stick to the contact surface. There is no need to hold the thickness gauge body, and you can concentrate on using the probe to measure the thickness and observe the thickness data through the thickness gauge body.
[0014] Preferably, a fixing post is provided on the left side of the outer shell body and is interlocked with the anti-slip hand strap, and the bottom anti-slip strip, side anti-slip strip, finger pad and strap are all made of silicone rubber material.
[0015] The above technical solution utilizes silicone rubber to create a bottom anti-slip strip, side anti-slip strips, finger pads, and a strap, which enhances friction. When gripping, the fingertips contact the side anti-slip strips, while the strap and finger pads cover the palm and back of the hand. Friction alone is enough to prevent the portable thickness gauge from slipping out of the hand, improving portability. The material is also skin-friendly and comfortable to the touch. An anti-slip wrist strap is included; when holding the portable thickness gauge, the user can slip the anti-slip wrist strap onto their wrist, which, together with the strap, forms a double safety measure, preventing the portable thickness gauge from falling and being damaged. This is highly practical.
[0016] Preferably, the thickness gauge body is equipped with dual CPUs, and the thickness gauge body adopts a dual-crystal probe method.
[0017] Through the above technical solution, the thickness gauge body is equipped with dual CPUs working in tandem, with the instrument control part and data processing part working independently. The system operates at high speed and is reliable, with excellent field performance. It adopts a dual-crystal probe method, using dual-crystal probes to measure the thinning of pipe walls in internally corroded pipe fittings, and to accurately detect the true thickness of workpieces coated with paint. Combined with the echo-to-echo function of the thickness gauge body, the thickness of paint or coating can be ignored, and the true thickness of the workpiece can be accurately measured.
[0018] Preferably, the display uses a 2.4-inch true color display screen, the thickness gauge body uses three AA alkaline dry batteries as power sources, the gain range of the thickness gauge body is 0dB to 52dB, the detection range is 0.0mm to 625.0mm, the bandwidth is 0.5MHz to 15.0MHz, and the sound velocity range is 5000 to 9999m / s.
[0019] Through the above technical solution, the thickness gauge body uses three replaceable AA alkaline dry batteries as its power source. It can be used continuously by replacing the batteries. The thickness gauge body has a wide measurement range and accuracy. It is equipped with a display with a true color screen, which has a good display effect. It can obtain satisfactory observation results without the need for a sunshade under strong sunlight.
[0020] Compared with the prior art, the portable thickness gauge provided by this utility model has the following advantages:
[0021] 1. This portable thickness gauge features a shell made of nitrile rubber, offering strong wear resistance and protection, thus extending its lifespan. It includes a finger pad with four arc-shaped grooves to ergonomically fit the fingers. A suction cup is also included; when thickness measurement is required, the gauge can be placed on a smooth, vertical surface, and the suction cup will adhere firmly without needing to hold the gauge. This allows for focused use of the probe for thickness measurement. The instrument body measures thickness data and features a bottom anti-slip strip, side anti-slip strips, finger pads, and a strap made of silicone rubber, which enhances friction. When gripping, the fingertips contact the side anti-slip strips, while the strap and finger pads cover the palm and back of the hand. Friction alone is enough to prevent the portable thickness gauge from slipping out of the hand, improving portability. At the same time, the material is skin-friendly and comfortable to the touch. An anti-slip wrist strap is also included. When holding the portable thickness gauge, the user can put the anti-slip wrist strap on their wrist, which, together with the strap, forms a double safety measure, making the portable thickness gauge less likely to fall and be damaged. It is very practical.
[0022] 2. This portable thickness gauge features a dual-CPU design, with the control and data processing sections operating independently. The system boasts high-speed, reliable operation and excellent field performance. Employing a dual-crystal probe, it measures the wall thinning of corroded pipes and accurately detects the true thickness of painted workpieces. Combined with the echo-to-echo function, the thickness of the coating or paint layer can be ignored, ensuring precise measurement of the workpiece's true thickness. Powered by three AA alkaline batteries, continuous operation is achieved simply by replacing the batteries. The gauge offers a wide measurement range and high accuracy, and its true-color display provides excellent visual quality, allowing for satisfactory observation even in strong sunlight without the need for a sunshade.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0031] Example 1:
[0032] See Figures 1 to 3 as well as Figure 6 The diagram illustrates the configuration of a portable thickness gauge as provided in this example. Based on the diagram, this portable thickness gauge specifically includes a protective housing 1, a thickness gauge body 2, a display 3, and control buttons 4. The thickness gauge body 2 is housed inside the protective housing 1, and the display 3 and control buttons 4 are located on the upper surface of the thickness gauge body 2. An anti-slip hand strap 5 is located on the left side of the protective housing 1.
[0033] See further Figure 4 and Figure 5 The protective housing 1 of this portable thickness gauge specifically includes a housing body 101, a bottom anti-slip strip 102, side anti-slip strips 103, a finger pad 104, a connecting ring 105, a strap 106, and a suction cup 107. Specifically, the bottom anti-slip strip 102 is provided at the front end of the housing body 101, the side anti-slip strips 103 are provided on both sides of the housing body 101, the finger pad 104 is provided at the lower end of the housing body 101, the connecting ring 105 is fixedly connected to the lower end of the housing body 101, the strap 106 is fixedly connected to the center of the connecting ring 105, and the suction cup 107 is fixedly connected to the upper end of the housing body 101.
[0034] Furthermore, in this example, the outer shell 101 is sleeved on the outside of the thickness gauge body 2, and the outer shell 101 is made of nitrile rubber. Thus, the outer shell 101 made of nitrile rubber has strong wear resistance, provides protection for the thickness gauge body 2, and extends the service life of the thickness gauge body 2.
[0035] Furthermore, in this example, four arc-shaped grooves are formed on the lower surface of the finger pad 104, and the strap 106 is positioned below the finger pad 104. Thus, the finger pad 104, with its four arc-shaped grooves, matches the fingers, conforming to ergonomics. When the user holds the device, the fingers are positioned within the arc-shaped grooves of the finger pad 104, and the strap 106 contacts the back of the hand, providing good restraint. This prevents the protective shell 1 and the thickness gauge body 2 from slipping out of the hand, resulting in good portability.
[0036] Furthermore, in this example, three identical suction cups 107 are provided, arranged in an equilateral triangle structure. With the suction cups 107 in place, when thickness measurement is required, the thickness gauge body 2 can be placed on a relatively smooth vertical surface, and the suction cups 107 can be pressed firmly against the contact surface. There is no need to hold the thickness gauge body 2; one can concentrate on using the probe to measure thickness and observe the thickness data through the thickness gauge body 2.
[0037] Example 2:
[0038] This example presents a portable thickness gauge configuration scheme, and this example further provides an improved scheme.
[0039] Combination Figures 4 to 6 As shown, in this example, a fixing post is further provided on the left side of the outer shell body 101 and is interlocked with the anti-slip hand strap 5. The bottom anti-slip strip 102, the side anti-slip strip 103, the finger pad 104 and the strap 106 are all made of silicone rubber material.
[0040] Thus, in this example, by using a bottom anti-slip strip 102, side anti-slip strip 103, finger pad 104, and strap 106 made of silicone rubber, the friction is improved. When holding the instrument, the fingertips contact the side anti-slip strip 103, and the strap 106 and finger pad 104 cover the palm and back of the hand. The friction alone is enough to prevent the portable thickness gauge from slipping out of the hand, improving portability. At the same time, the material is skin-friendly and comfortable to the touch. An anti-slip wrist strap 5 is also provided. When the user holds the portable thickness gauge, the anti-slip wrist strap 5 is put on the wrist, which, together with the strap 106, forms a double safety measure, making it less likely for the portable thickness gauge to fall and be damaged. It is very practical.
[0041] In some implementations of this example, the thickness gauge body 2 is equipped with dual CPUs, and the thickness gauge body 2 adopts a dual-crystal probe method.
[0042] Thus, this example features a dual-CPU system in the thickness gauge body 2, with the instrument control and data processing sections operating independently. The system operates at high speed and with excellent field performance. It employs a dual-crystal probe to measure the wall thinning of pipes with internal corrosion and to accurately detect the true thickness of workpieces coated with paint. Combined with the echo-to-echo function of the thickness gauge body 2, the thickness of the paint or coating can be ignored, allowing for precise measurement of the true thickness of the workpiece.
[0043] In some embodiments of this example, the display 3 uses a 2.4-inch true color display screen, the thickness gauge body 2 uses three replaceable AA alkaline dry batteries as power sources, and the thickness gauge body 2 is specifically configured with a gain range of 0dB to 52dB, a detection range of 0.0mm to 625.0mm, a bandwidth of 0.5MHz to 15.0MHz, and a sound velocity range of 5000 to 9999m / s.
[0044] The specific composition of the thickness gauge body 2 is not limited here and can be determined according to actual needs. As an example, an existing stable and reliable design scheme can be adopted, the composition of which is well known to those skilled in the art and will not be described in detail here.
[0045] Thus, in this example, the thickness gauge body 2 uses three replaceable AA alkaline dry batteries as its power source. It can be used continuously by replacing the batteries. The thickness gauge body 2 has a wide measurement range and accuracy. It is equipped with a display 3 with a true color screen, which has a good display effect. It can obtain satisfactory observation results without the need for a sunshade under strong sunlight.
[0046] Regarding the thickness gauge based on the above scheme, its usage process will be explained in detail below, taking into account its composition.
[0047] Combination Figures 1 to 6 When using this portable thickness gauge, the user can hold it with their fingertips in contact with the side anti-slip strip 103. The strap 106 and finger pads 104 cover the palm and back of the hand. The side anti-slip strip 103, finger pads 104, and strap 106 are made of silicone rubber, which provides high friction and prevents the portable thickness gauge from slipping out of the hand. The anti-slip wrist strap 5, together with the strap 106, forms a double safety mechanism, preventing the portable thickness gauge from falling and being damaged. This is very practical and improves portability. The material is also skin-friendly and comfortable to the touch. When thickness measurement is needed, the thickness gauge body 2 can be placed on a smooth vertical surface. Pressing the thickness gauge body 2 causes the suction cup 107 to adhere firmly to the contact surface. Without needing to hold the thickness gauge body 2, the user can focus on using the probe for thickness measurement. The thickness gauge body 2 observes thickness data. It features dual CPUs working collaboratively, with the instrument control and data processing sections operating independently. The system operates at high speed and with excellent field performance. Employing a dual-crystal probe, it measures the wall thinning of corroded pipe fittings and accurately detects the true thickness of painted workpieces. Combined with the echo-to-echo function of the thickness gauge body 2, the thickness of the paint or coating can be ignored, allowing for precise measurement of the workpiece's true thickness. The thickness gauge body 2 uses three replaceable AA alkaline batteries for power; battery replacement ensures continuous operation. It boasts a wide measurement range and high accuracy, and features a true-color display 3 with excellent display quality. Satisfactory observation results can be obtained even in strong sunlight without the need for a sunshade.
[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
