Description

Technical Field

[0001] This utility model belongs to the technical field of ultrasonic thickness gauges, and in particular relates to a high-precision ultrasonic thickness measuring instrument. Background Technology

[0002] Ultrasonic thickness gauges measure 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 is determined by accurately measuring the propagation time of the ultrasonic wave within the material. This principle can be used to measure various materials that allow ultrasonic waves to propagate at a constant speed within them.

[0003] Because ultrasonic thickness gauges require a lead wire to connect the gauge and the probe, existing ultrasonic thickness gauges cannot protect the lead wire plug, which may detach under external force. Secondly, the probe does not have a protective structure, and it may be damaged if dropped or impacted, thus having a certain impact. Therefore, there is an urgent need for a high-precision ultrasonic thickness measuring instrument to solve the above problems. Utility Model Content

[0004] To solve the above problems, this utility model provides a high-precision ultrasonic thickness measuring instrument, which is achieved through the following technical solution.

[0005] A high-precision ultrasonic thickness measuring instrument includes an ultrasonic measuring instrument body and a connecting wire. One end of the connecting wire is electrically connected to the ultrasonic measuring instrument body via a plug, and the other end of the connecting wire is fixedly connected to an ultrasonic probe. The instrument also includes:

[0006] A positioning frame is fixedly connected to the top of the ultrasonic measuring instrument body for limiting the plug engagement.

[0007] A protective cover is fitted over the ultrasonic probe for protection.

[0008] Furthermore, the positioning frame has two limiting slots, and two symmetrical slots are provided inside the positioning frame, with limiting mechanisms installed inside the slots.

[0009] Furthermore, the limiting mechanism includes a baffle and a slide rod. One end of the baffle is rotatably connected to the slot, and the slide rod is fixedly connected to the inside of the slot. One end of the slide rod is movably connected to a movable seat. A spring fixed on the movable seat is sleeved on the slide rod. A support rod is rotatably connected to the movable seat, and the other end of the support rod is rotatably connected to the baffle.

[0010] Furthermore, one end of each of the two baffles is pressed against the outer surface of the plug.

[0011] Furthermore, the angle range of rotation between the baffle and the positioning frame is 0-30°.

[0012] Furthermore, the top of the protective cover is movably connected to the guide line, and the bottom of the protective cover is covered with a fixing cover, which is fixedly connected to the protective cover by a hanging rope.

[0013] Furthermore, the protective cover is made of plastic, and the fixing cover is made of rubber.

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-4 As shown, the present invention has the following specific embodiments.

[0027] Example 1

[0028] A high-precision ultrasonic thickness measuring instrument includes an ultrasonic measuring instrument body 1 and a connecting wire 2. One end of the connecting wire 2 is electrically connected to the ultrasonic measuring instrument body 1 through a plug 21, and the other end of the connecting wire 2 is fixedly connected to an ultrasonic probe 22. The instrument also includes:

[0029] Positioning frame 3 is fixedly connected to the top of the ultrasonic measuring instrument body 1 and is used to lock and limit the plug 21.

[0030] Protective cover 4 is fitted onto ultrasonic probe 22 for protection.

[0031] In this embodiment, as Figure 1 As shown, the plug 21 of the lead wire 2 can be connected to the socket on the ultrasonic measuring instrument body 1. The positioning frame 3 set on the ultrasonic measuring instrument body 1 can limit the connected plug 21 to prevent the lead wire 2 from being pulled off by external force. The protective cover 4 can be put on the ultrasonic probe 22 for protection. The structure is reasonable, has better protection effect, and can improve the durability of the device.

[0032] Example 2

[0033] The positioning frame 3 has two limiting slots 31, and the positioning frame 3 has two symmetrical slots 32 inside, with a limiting mechanism installed inside the slots 32.

[0034] Preferably, the limiting mechanism includes a baffle 33 and a slide rod 34. One end of the baffle 33 is rotatably connected to the slot 32, and the slide rod 34 is fixedly connected to the inside of the slot 32. One end of the slide rod 34 is movably connected to a movable seat 341. A spring 342 fixed on the movable seat 341 is sleeved on the slide rod 34. A support rod 343 is rotatably connected to the movable seat 341, and the other end of the support rod 343 is rotatably connected to the baffle 33.

[0035] Preferably, one end of each of the two baffles 33 is pressed against the outer surface of the plug 21;

[0036] Preferably, the angle range of rotation between the baffle 33 and the positioning frame 3 is 0-30°.

[0037] In this embodiment, as Figure 2 and 3 As shown, when the plug 21 is inserted into the limiting slot 31, it is pressed into the limiting slot 31 by external force. During the insertion process, the plug 21 presses against the baffle 33, and the compressed baffle 33 can rotate and be inserted into the slot 32. At this time, the angle between the baffle 33 and the positioning frame 3 is 0°. The baffle 33 pushes the movable seat 341 to move on the slide rod 34 through the rotating support rod 343, and the movable seat 341 compresses and stores energy in the spring 342 until the plug 21 is inserted into the limiting slot 31. At this time, the stored energy in the spring 342 is released. The position is adjusted so that the movable seat 341 is reset. The movable seat 341 pushes the baffle 33 to reset through the support rod 343. At this time, the baffle 33 and the positioning frame 3 form a 30° angle, so that one end of the baffle 33 is pressed against the plug 21. Conversely, when the plug 21 and the limiting slot 31 are disassembled, the baffle 33 is pressed into the slot 32, and the plug 21 can be disassembled from the limiting slot 31. This makes it easy to disassemble and assemble the plug 21 and the positioning frame 3. The positioning frame 3 can lock and limit the plug 21 to prevent the plug 21 from falling off the ultrasonic measuring instrument body 1.

[0038] Example 3

[0039] The top of the protective cover 4 is movably connected to the lead wire 2, and the bottom of the protective cover 4 is covered with a fixing cover 41. The fixing cover 41 is fixedly connected to the protective cover 4 by a hanging rope 411.

[0040] Preferably, the protective cover 4 is made of plastic and the fixing cover 41 is made of rubber.

[0041] In this embodiment, as Figure 4 As shown, the protective cover 4 is used to fit onto the ultrasonic probe 22. When the ultrasonic probe 22 is in use, the fixing cover 41 and the protective cover 4 are opened to facilitate the protection and use of the ultrasonic probe 22.

[0042] The working principle of this utility model:

[0043] When using the device, firstly, the plug 21 of the lead wire 2 can be connected to the socket on the ultrasonic measuring instrument body 1;

[0044] Then, the positioning frame 3 on the ultrasonic measuring instrument body 1 can limit the connection of the plug 21. When the plug 21 is inserted into the limiting slot 31, it is pressed into the limiting slot 31 by external force. During the insertion process, the plug 21 presses against the baffle 33. The compressed baffle 33 can rotate and be inserted into the slot 32. At this time, the angle between the baffle 33 and the positioning frame 3 is 0°. The baffle 33 pushes the movable seat 341 to move on the slide rod 34 through the rotating support rod 343, and the movable seat 341 compresses and stores energy in the spring 342 until the plug 21 is inserted into the limiting slot 31. When the device is in operation, the stored energy spring 342 releases its energy and resets, thereby pushing the movable seat 341 to reset. The movable seat 341 pushes the baffle 33 to reset via the support rod 343. At this time, the baffle 33 and the positioning frame 3 form a 30° angle, so that one end of the baffle 33 presses against the plug 21. Conversely, when the plug 21 and the limiting slot 31 are disassembled, the baffle 33 is pressed into the slot 32, and the plug 21 can be disassembled from the limiting slot 31, which facilitates the disassembly and assembly of the plug 21 and the positioning frame 3. The positioning frame 3 can lock and limit the plug 21 to prevent the plug 21 from detaching from the ultrasonic measuring instrument body 1.

[0045] Finally, the protective cover 4 can be fitted onto the ultrasonic probe 22 for protection. The protective cover 4 is used to fit onto the ultrasonic probe 22. When the ultrasonic probe 22 is in use, the fixing cover 41 and the protective cover 4 are opened to facilitate the protection and use of the ultrasonic probe 22.

[0046] With its reasonable structure, it provides better protection and improves the durability of the device.
