Description

Technical Field

[0001] This utility model relates to the field of replaceable probe coating thickness measurement technology, specifically to a replaceable probe coating thickness measurement device. Background Technology

[0002] Coating thickness gauges mainly employ two measurement principles: magnetic thickness measurement and eddy current thickness measurement. Magnetic thickness measurement, based on the principle of magnetic flux, is suitable for measuring the thickness of non-magnetic coatings on magnetic metal substrates. When the probe contacts the coating, the probe and the magnetic substrate form a closed magnetic circuit. Changes in coating thickness cause changes in the magnetic reluctance of the magnetic circuit, which in turn leads to a change in the magnetic flux through the circuit. The instrument determines the coating thickness by measuring this change in magnetic flux.

[0003] Eddy current thickness measurement utilizes the principle of eddy currents generated in a conductor by an alternating magnetic field to measure the thickness of insulating coatings on non-magnetic metal substrates. The alternating magnetic field generates eddy currents on the surface of the metal substrate; the magnitude of these eddy currents changes depending on the coating thickness. The instrument determines the coating thickness by detecting these changes in eddy currents. Both of these principles can meet the coating thickness measurement needs of different materials and application scenarios.

[0004] The probe of the coating thickness measuring instrument is the core detection component. Its performance directly determines the measurement accuracy, repeatability, and applicable scenarios. To adapt to different materials (such as magnetic materials and non-magnetic materials) or special process scenarios, the probe needs to be replaced. When replacing the probe, the instrument power must be turned off. Some instruments use a wrench to loosen the probe fixing screws and then remove the probe. Such frequent probe replacement may lead to mechanical wear and aging, reduce the stability and reliability of contact, shorten the service life of the equipment, and increase maintenance and replacement costs. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides a device for measuring coating thickness with a replaceable probe.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a coating thickness measuring device with a replaceable probe, comprising a coating thickness measuring instrument, wherein a probe is inserted into the right side of the coating thickness measuring instrument, and further comprising:

[0007] The slots are symmetrically arranged on the front and rear sides of the coating thickness measuring instrument. A partition is fixedly connected inside the slot, a sliding sleeve is fixedly connected inside the partition, a push rod is slidably connected inside the sliding sleeve, and a button is fixedly connected to one end of the push rod.

[0008] The slot is located on the front and rear sides of the probe. Two spring rods b are fixed to the inner wall of the rear side of the slot. The telescopic end of the spring rod b is fixed with a locking block, which is engaged in the slot.

[0009] Preferably, the shape of the card block is a solid right triangle.

[0010] Preferably, a spring is sleeved on the push rod, the rear side of the spring is fixedly connected to the front side of the partition, and the rear side of the spring is fixedly connected to the rear side of the button.

[0011] Preferably, the inner wall of the right side of the slot is provided with a telescopic groove, and a plurality of spring rods a are vertically and evenly fixed to the telescopic groove. A push plate is fixed to the telescopic end of the spring rod a, and the push plate is in contact with the right side of the card block.

[0012] Preferably, the coating thickness measuring instrument has two external threaded sleeves fixedly connected to its front and rear sides, and the external threaded sleeves are fitted with threaded caps.

[0013] Preferably, the position of the external threaded sleeve corresponds to the position of the button.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention solves the problem that frequent probe insertion into the groove on the right side of the coating thickness measuring instrument causes the compression block to retract into the slot. After the probe is inserted into the groove, spring rod b pushes the compression block into the slot, and spring rod a pushes the push plate to tightly insert the compression block and probe into the coating thickness measuring instrument. Pressing two buttons pushes two push rods to compress the compression block closer to each other, causing the compression block to retract into the slot. Pulling the probe allows it to be detached from the coating thickness measuring instrument. This invention solves the problem that frequent probe replacement in existing devices may lead to mechanical wear and aging, reduce contact stability and reliability, and shorten the service life of the equipment.

[0016] This invention protects the button with an external threaded sleeve and a threaded cap to prevent accidental button activation and probe detachment. Attached Figure Description

[0028] The slot 12 is located on the front and rear sides of the probe 2. Two spring rods b13 are fixed to the inner wall of the rear side of the slot 12. The telescopic ends of the spring rods b13 are fixed to the locking blocks 14, which are engaged in the slot 4.

[0029] In this embodiment, as Figures 1-2 ,as well as Figures 3-4 As shown, the probe 2 is inserted into the groove on the right side of the coating thickness measuring instrument 1. The groove compression block 14 retracts into the slot 12. After the probe 2 is inserted into the groove on the right side of the coating thickness measuring instrument 1, the spring rod b13 pushes the block 14 into the slot 4. The spring rod a10 pushes the push plate 11 to make the block 14 and the probe 2 tightly inserted into the coating thickness measuring instrument 1.

[0030] Pressing the two buttons 3 pushes the two push rods 7 to compress the locking block 14 closer to each other. The locking block 14 retracts into the slot 12. Pulling the probe 2 will disengage the probe 2 from the coating thickness measuring instrument 1. After the probe 2 is disengaged from the coating thickness measuring instrument 1, the spring 8 pushes the button 3 to return to its original position.

[0031] Example 2

[0032] The difference from Embodiment 1 is that this embodiment discloses the internal structure of slot 4:
