For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] See also Figures 1 to 3 The embodiment of the present application provides a waterproof coating thickness measuring needle, including a probe chamber 1, a probe 2, a driving unit 3, a first disc level 4, and a second disc level 5. The probe 2 is arranged in the probe chamber 1; the driving unit 3 is arranged on the probe chamber 1, and the driving unit 3 drives the probe 2 to move up and down along the top surface of the vertical probe chamber 1; the first disc level 4 is horizontally arranged on the top surface of the probe chamber 1; the second disc level 5 is arranged on the side of the probe chamber 1, and is perpendicular to the top surface of the probe chamber 1.

[0034] The waterproof coating thickness measuring needle provided in this embodiment can ensure that the probe 2 remains vertical when piercing the coating by setting two disc levels (one located on the top surface of the probe chamber 1 and the other located on the side of the probe chamber 1), effectively avoiding the measurement error caused by the non-vertical insertion angle of the probe 2. In addition, when the detection surface is a horizontal surface (such as the ground, etc.), the angle of the probe 2 is mainly verified by the first disc level 4 to ensure the measurement accuracy. When the detection surface is a vertical surface (such as a wall, etc.), the angle of the probe 2 is verified by the second disc level 5. This makes the waterproof coating thickness measuring needle in this embodiment suitable for waterproof coating thickness detection on horizontal or vertical surfaces, and has high adaptability.

[0035] like Figure 2 As shown, in one embodiment, the driving part 3 includes a push pin block 33, a connecting rod 32, and a pull ring 31. The pull ring 31 is slidably arranged on the probe chamber 1; one end of the connecting rod 32 is movably riveted to the pull ring 31; the push pin block 33 is movably riveted to the other end of the connecting rod 32, and the probe 2 is fixed on the push pin block 33. When measurement is required, it is only necessary to give an outward pulling force to the pull rings 31 on both sides so that the pull rings 31 on both sides are separated, thereby driving one end of the connecting rod 32 to move outward (a slit is provided on the probe chamber 1 to facilitate the movement of the connecting rod 32, so that the probe chamber 1 will not restrict the movement of the connecting rod 32), so that the other end of the connecting rod 32 presses down the push pin block 33, so that the push pin block 33 presses down the probe 2 for measurement.

[0036] In one embodiment, the driving unit 3 also includes a probe clip 34 and an elastic member 35. The other end of the pull ring 31 is located in the probe chamber 1, and the probe clip 34 is fixed to one end of the pull ring 31 located in the probe chamber 1; the elastic member 35 is sleeved on the pull ring 31, and one end of the elastic member 35 is against the probe clip 34, and the elastic member 35 is in a compressed state.

[0037] The elastic member 35 may be a spring. The elastic member 35 gives the pull ring 31 and the probe clip 34 an elastic force toward the probe 2. Under the action of this force, the pull rings 31 on both sides are retracted until the probe clip 34 clamps the probe 2. During the retraction process of the pull rings 31 on both sides, the pull ring 31 drives the connecting rod 32, so that the push needle block 33 lifts the probe 2, and then the probe 2 can be automatically retracted into the probe chamber 1 under the elastic force of the elastic member 35, and the probe 2 is fixed by the probe clip 34.

[0038] In one embodiment, a cylindrical concave surface is disposed on one side of the probe clip 34 close to the probe 2 , and the radius of the cylindrical concave surface is the same as the radius of the probe 2 , thereby facilitating the probe clip 34 to clamp the probe 2 .

[0039] In one embodiment, a cover 6 is provided on the bottom surface of the probe chamber 1, and a pinhole 61 is provided on the cover 6. The design of the cover 6 and the pinhole 61 can protect the probe 2 from damage or contamination during transportation and storage. When measurement is required, the probe 2 can be extended from the pinhole 61; when the measurement is completed, the probe 2 can be retracted into the probe chamber 1 and closed by the cover 6. This design not only facilitates the use and storage of the probe 2, but also improves the safety and reliability of the measurement.

[0040] In one embodiment, a scale ring is provided at the bottom tip of the probe 2. The design of the scale ring enables the user to visually observe the depth of the probe 2 penetrating into the coating, thereby conveniently measuring and recording. At the same time, the scale ring can also be used as a calibration tool to ensure the accuracy and reliability of the measurement.

[0041] In one embodiment, a handle 7 is provided on the outer side of the probe chamber 1, and the second disc level 5 is fixed on the handle 7. By providing the handle 7, the user can hold and operate the probe chamber 1 more conveniently.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
