Description

Technical Field

[0001] The utility model relates to the technical field of insulating material thickness detection, in particular to an instrument for automatically detecting the thickness of insulating materials. Background Art

[0002] The main function of a solid electrical insulator is to prevent current or voltage from leaking along a path where it should not flow. By testing its thickness, it can be ensured that the insulator can effectively isolate current and voltage, thereby protecting the safe operation of circuits and equipment. The insulation thickness is designed based on its ability to safely withstand various possible voltage conditions during its expected service life. Testing the thickness can verify whether the insulator meets the design requirements and ensure that it will not break down during use due to insufficient thickness.

[0003] However, when testing the thickness of the insulating material used for the cable sheath, since it is necessary to directly sample from the cable, the sampled product has a certain arc shape. Therefore, during the test, the curvature will cause the test result to be inaccurate. Therefore, an automatic insulation material thickness meter is needed to solve the above problem. Utility Model Content

[0004] The utility model aims to provide an automatic thickness detection instrument for insulating materials, which has the advantage of conveniently detecting the thickness of insulating materials with curvature, and solves the problem that the detection result is easily inaccurate when the insulating materials have curvature.

[0005] To achieve the above object, the utility model provides the following technical solutions: an automatic insulating material thickness detection instrument, comprising a base and a display mechanism, a top plate movably mounted on the upper surface of the base, a detection hole is opened in the middle of the upper surface of the top plate, and also includes a shell;

[0006] The shell is movably installed above the detection hole;

[0007] Among them, a distance sensor is embedded in the shell, and an electric telescopic rod is fixedly installed on the top of the shell;

[0008] Wherein, the distance sensor is electrically connected to the display mechanism through a connecting wire.

[0009] When using an automatic insulating material thickness meter in the technical solution, the insulating part is placed on the upper surface of the base to ensure that it is located below the reserved groove, the insulating part is clamped by the top plate and the opposite side of the base, the insulating part is flattened by the top plate and the limit spring, and due to the presence of the detection hole, the insulating part at the detection hole position can be used for detection, and the electric telescopic rod is started to adjust the height of the bottom of the shell, and after the bottom of the shell contacts the insulating part, the pressure sensor is used to prevent the shell from applying pressure to the insulating part. At this time, the distance between the insulating part and the distance sensor can be measured by the distance sensor, and the data is displayed on the display mechanism. At this time, the electric telescopic rod can be closed, and the insulating part can be pulled out from between the bottom plate and the base. At the same time, the electric telescopic rod is started again, so that the bottom shell moves down and the bottom contacts the upper surface of the base. At this time, the distance between the distance sensor and the upper surface of the base can be measured by the distance sensor and displayed on the display mechanism. The thickness of the insulating part is obtained by subtracting the data.

[0010] Preferably, slide bars are fixedly installed at the four corners of the upper surface of the base, and the front and rear ends of the upper surface of the base are elastically connected to the top plate through limit springs.

[0011] This design allows the top plate to move vertically above the base flexibly to accommodate insulation of varying thicknesses. The elastic connection ensures that the top plate can apply appropriate pressure when flattening the insulation while avoiding overpressure that could damage the material.

[0012] Preferably, the tops of the four sliding rods are fixedly connected by a connecting frame, a mounting frame is fixedly installed on the inner side of the connecting frame, and the top of the electric telescopic rod is embedded and installed on the inner side of the mounting frame.

[0013] This structural design makes the movement of the electric telescopic rod more stable and precise, ensuring the accuracy and repeatability during the measurement process. At the same time, the fixed connection between the connecting frame and the mounting frame also enhances the stability of the overall structure.

[0014] Preferably, reserved holes are respectively opened at the four corners of the upper surface of the top plate, the slide rod is slidably installed in the reserved holes, a reserved groove is opened on the lower surface of the top plate, an insulating part is clamped on the side opposite to the base, and a lifting frame is fixedly installed on the upper surface of the top plate.

[0015] This design allows the top plate to hold the insulation in the same position and to perform the lifting operation via the lifting frame, ensuring the stability and accuracy of the insulation during measurement.

[0016] Preferably, the insulating member is movably placed on the upper surface of the base below the reserved groove, and the width of the insulating member is smaller than the width of the reserved groove and larger than the width of the detection hole.

[0017] This size design ensures that the insulating part will not slip out of the reserved groove during the measurement process. At the same time, the size limit of the detection hole ensures the accuracy of the measurement. The width limit of the insulating part also enables it to be fully covered during measurement, thereby improving the reliability of the measurement results.

[0018] Preferably, the lifting frame is made of hard rubber material, has a triangular structure and does not contact the mounting frame.

[0019] The hard rubber material provides good durability and elasticity, ensuring that the lifting frame is not easily damaged during long-term use. The triangular structure design provides stability. At the same time, the design that does not contact the mounting frame avoids additional friction and wear, and improves the smoothness of operation.

[0020] Preferably, the size of the bottom of the shell matches the size of the detection hole, a pressure sensor is embedded and installed on the outer side of the bottom of the shell, and the pressure sensor is electrically connected to the electric telescopic rod.

[0021] This design allows the shell to fit tightly against the detection hole, ensuring stability during the measurement process. The electrical connection of the pressure sensor can monitor and adjust the pressure in real time to ensure the accuracy of the measurement.

[0022] Preferably, the monitoring end of the distance sensor is located at the bottom, and the height of the bottom of the distance sensor is higher than the height of the bottom of the shell.

[0023] This design enables the distance sensor to measure the thickness of the insulating part more accurately. The setting of the bottom height also avoids direct contact between the sensor and the insulating part, reduces measurement errors, and improves measurement accuracy.

[0024] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0025] The utility model movably installs the shell above the detection hole. This design makes the shell height adjustable according to the thickness of the insulating material, ensuring that the bottom of the shell always keeps in contact with the surface of the insulating material during measurement. In cooperation with the top plate and the base, the spread insulating member can be detected, and the detection position is located at the detection hole. The distance sensor is embedded in the shell so that the sensor can be closer to the surface of the insulating material, thereby improving the measurement accuracy. The electric telescopic rod can adjust the distance between the shell and the insulating material to ensure that the shell and the material surface are closely fitted. The display mechanism is directly electrically connected to the distance sensor and can display the measurement result in real time, making it convenient for the operator to read and record data, thereby achieving the effect of convenient thickness detection of insulating materials with curvature.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Example

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the utility model is: an automatic insulating material thickness detection instrument, including a base 1 and a display mechanism 7, a top plate 4 is movably mounted on the upper surface of the base 1, a detection hole 14 is opened in the middle of the upper surface of the top plate 4, and a shell 3;

[0034] Specifically, by movably installing the shell 3 above the detection hole 14, this design allows the height of the shell 3 to be adjusted according to the thickness of the insulating material, ensuring that the bottom of the shell 3 always maintains contact with the surface of the insulating material during measurement. In conjunction with the top plate 4 and the base 1, the spread insulating member 5 can be detected, and the detection position is located at the detection hole 14. The distance sensor 12 is embedded in the shell 3, so that the sensor can be closer to the surface of the insulating material, thereby improving the measurement accuracy. The electric telescopic rod 11 can adjust the distance between the shell 3 and the insulating material to ensure that the shell 3 is tightly fitted to the material surface. The display mechanism 7 is directly electrically connected to the distance sensor 12, and can display the measurement results in real time, making it convenient for the operator to read and record data, thereby achieving the effect of facilitating thickness detection of insulating materials with curvature.

[0035] Furthermore, slide bars 10 are fixedly installed at the four corners of the upper surface of the base 1, and the front and rear ends of the upper surface of the base 1 are elastically connected to the top plate 4 through limit springs 2.

[0036] This design enables the top plate 4 to flexibly move vertically above the base 1 to accommodate insulating members 5 of different thicknesses. The elastic connection ensures that the top plate 4 can apply appropriate pressure when flattening the insulating member 5 while avoiding overpressure damage to the material.

[0037] Furthermore, the tops of the four slide rods 10 are fixedly connected by a connecting frame 6 , a mounting frame 8 is fixedly installed on the inner side of the connecting frame 6 , and the top of the electric telescopic rod 11 is embedded and installed on the inner side of the mounting frame 8 .

[0038] This structural design makes the movement of the electric telescopic rod 11 more stable and precise, ensuring the accuracy and repeatability during the measurement process. At the same time, the fixed connection between the connecting frame 6 and the mounting frame 8 also enhances the stability of the overall structure.

[0039] Furthermore, reserved holes 13 are respectively opened at the four corners of the upper surface of the top plate 4, and the sliding rod 10 is slidably installed in the reserved holes 13. A reserved groove is opened on the lower surface of the top plate 4. An insulating part 5 is clamped on the side opposite to the base 1, and a lifting frame 9 is fixedly installed on the upper surface of the top plate 4.

[0040] This design allows the top plate 4 to fix the insulating member 5 at the same position and perform a lifting operation through the lifting frame 9, thereby ensuring the stability and accuracy of the insulating member 5 during the measurement process.

[0041] Furthermore, the insulating member 5 is movably placed on the upper surface of the base 1 below the reserved groove, and the width of the insulating member 5 is smaller than the width of the reserved groove and larger than the width of the detection hole 14 .

[0042] This size design ensures that the insulating member 5 will not slip out of the reserved groove during the measurement process. At the same time, the size limit of the detection hole 14 ensures the accuracy of the measurement. The width limit of the insulating member 5 also enables it to be fully covered during measurement, thereby improving the reliability of the measurement result.

[0043] Furthermore, the lifting frame 9 is made of hard rubber material, has a triangular structure and does not contact the mounting frame 8 .

[0044] The hard rubber material provides good durability and elasticity, ensuring that the lifting frame 9 is not easily damaged during long-term use. The triangular structure design provides stability. At the same time, the design of non-contact with the mounting frame 8 avoids additional friction and wear, thereby improving the smoothness of operation.

[0045] Furthermore, the size of the bottom of the shell 3 matches the size of the detection hole 14 , and a pressure sensor is embedded and installed on the outer side of the bottom of the shell 3 , and the pressure sensor is electrically connected to the electric telescopic rod 11 .

[0046] This design enables the housing 3 to fit closely with the detection hole 14, ensuring stability during the measurement process, and the electrical connection of the pressure sensor can monitor and adjust the pressure in real time to ensure the accuracy of the measurement.

[0047] Furthermore, the monitoring end of the distance sensor 12 is located at the bottom, and the bottom height of the distance sensor 12 is higher than the bottom height of the housing 3 .

[0048] This design enables the distance sensor 12 to measure the thickness of the insulating member 5 more accurately. The setting of the bottom height also avoids direct contact between the sensor and the insulating member 5, reduces measurement errors, and improves measurement accuracy.

[0049] When the utility model is used, the insulating member 5 is placed on the upper surface of the base 1 to ensure that it is located below the reserved groove, the insulating member 5 is clamped by the top plate 4 and the side opposite to the base 1, and the insulating member 5 is flattened by the top plate 4 and the limit spring 2. Due to the existence of the detection hole 14, the insulating member 5 at the position of the detection hole 14 can be used for detection, and the electric telescopic rod 11 is started, so that the height of the bottom of the shell 3 can be adjusted. After the bottom of the shell 3 contacts the insulating member 5, the pressure sensor is used to prevent the shell 3 from applying pressure to the insulating member 5. At this time, the distance between the insulating member 5 and the distance sensor 12 can be measured by the distance sensor 12, and the data is displayed on the display mechanism 7. At this time, the electric telescopic rod 11 can be closed, and the insulating member 5 can be pulled out from between the bottom plate and the base 1. At the same time, the electric telescopic rod 11 is started again, so that the bottom shell moves downward and the bottom contacts the upper surface of the base 1. At this time, the distance between the distance sensor 12 and the upper surface of the base 1 can be measured by the distance sensor 12, and displayed on the display mechanism 7. The thickness of the insulating member 5 is obtained by subtracting the data.
