Description

Technical Field

[0001] This utility model relates to the field of measurement technology for film-type microwave absorbing materials, and in particular to a thickness measuring device for film-type microwave absorbing materials. Background Technology

[0002] Film-type microwave absorbing materials (thin film microwave absorbing materials) are functional thin film materials made by using flexible polymer materials as the matrix and combining them with high magnetic permeability materials (such as ferrite, magnetic nanoparticles) or carbon-based materials (such as graphene, carbon nanotubes).

[0003] When inspecting the thickness of existing film-type microwave absorbing materials, it is necessary to first lift the film-absorbing material and then place it between the two round heads to test the thickness. During the test, since the upper and lower round heads of the thickness gauge and the film-absorbing material are not on the same horizontal plane, the test results will have errors. Each inspector has a different technique, and the test results will also be biased, which will affect the measurement accuracy. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the existing technology, when inspecting the thickness of film-type microwave absorbing materials, it is necessary to first lift the film-type microwave absorbing material and then place it between two round heads to test the thickness. During the test, because the upper and lower round heads of the thickness gauge and the film-type microwave absorbing material are not on the same horizontal plane, the test results are inaccurate. Furthermore, each inspector's technique is different, and the test results are also biased, which in turn affects the measurement accuracy.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a thickness measuring device for a film-type microwave absorbing material, comprising an operating table, a planar thickness measuring component provided at the rear end of the operating table, the planar thickness measuring component including a slot, a thickness gauge provided inside the slot, a base plate connected to the bottom of the thickness gauge, and locking blocks fixedly connected to both outer surfaces of the thickness gauge.

[0006] Furthermore, the outer surface of the card block is in contact with the inner wall of the card slot, and a sliding connection is formed between the card block and the card slot.

[0007] Furthermore, each of the four bottom corners of the base plate is connected to a convenient disassembly and assembly component, which includes a sleeve.

[0008] Furthermore, a spring is connected inside the sleeve, and a hand-tightening bolt is connected through the inside of the spring.

[0009] Furthermore, a limiting block is fixedly connected to the surface of the hand-tightening bolt, and threaded holes are opened on the bottom surface of the operating table that matches the four sets of hand-tightening bolts.

[0010] Furthermore, the limiting block and the spring form an elastic structure, and the hand-tightening bolt, after passing through the sleeve, forms a threaded connection with the threaded hole.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the thickness gauge measures the thickness of the sample by clamping the material between the upper and lower round heads. The thickness gauge is directly embedded and fixed on the operating table, so that the surface of the lower round head of the thickness gauge is flush with the table. During the test, it is only necessary to lift the upper round head of the thickness gauge and move the absorbing film horizontally on the table so that it is located between the upper and lower round heads for thickness measurement, which improves the accuracy of material measurement.

[0012] 2. In this utility model, when the thickness gauge needs to be disassembled for inspection and maintenance, the hand-tightening bolt can be turned to remove the thickness gauge from the fixing. After the thickness gauge is inspected and repaired, the hand-tightening bolt can be tightened to fix it. At the same time, the elasticity of the spring will also reduce the possibility of the hand-tightening bolt loosening, thus improving the disassembly and assembly efficiency.

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Examples, such as Figure 1 - Figure 4As shown, this utility model provides a thickness measuring device for a film-type microwave absorbing material, including an operating table 1. A planar thickness measuring component 2 is provided at the rear end of the operating table 1. The planar thickness measuring component 2 includes a slot 201. A thickness gauge 202 is provided inside the slot 201. A base plate 203 is connected to the bottom of the thickness gauge 202. A locking block 204 is fixedly connected to both outer surfaces of the thickness gauge 202.

[0018] like Figure 2 As shown, the outer surface of the card block 204 is in contact with the inner wall of the card slot 201, and a sliding connection is formed between the card block 204 and the card slot 201.

[0019] like Figure 1 - Figure 3 As shown, each of the four corners of the bottom of the base plate 203 is connected to a convenient disassembly and assembly component 3, which includes a sleeve 301.

[0020] like Figure 4 As shown, a spring 302 is connected inside the sleeve 301, and a hand-tightening bolt 303 is connected through the inside of the spring 302.

[0021] like Figure 2 and Figure 4 As shown, a limiting block 304 is fixedly connected to the surface of the hand-tightening bolt 303, and threaded holes are opened on the bottom surface of the operating table 1 that matches the four sets of hand-tightening bolts 303.

[0022] like Figure 4 As shown, the limiting block 304 and the spring 302 form an elastic structure, and the hand-tightening bolt 303 passes through the sleeve 301 and forms a threaded connection with the threaded hole.

[0023] The embodiment achieves the following effect: the thickness gauge 202 is directly pushed into the slot 201 via the two side locking blocks 204. The thickness gauge 202 measures the thickness of the sample by clamping the material between the upper and lower round heads. The thickness gauge 202 is directly embedded and fixed on the operating table 1, so that the surface of the lower round head of the thickness gauge 202 is flush with the table. During testing, it is only necessary to lift the upper round head of the thickness gauge 202 and move the absorbing film horizontally on the table to position it between the upper and lower round heads for thickness measurement, which improves the accuracy of material measurement. When it is necessary to disassemble the thickness gauge 202... During disassembly, inspection, and maintenance, the hand-tightening bolt 303 can be rotated in the opposite direction to remove its front end from the threaded hole, thus removing the thickness gauge 202 from its fixation. After the thickness gauge 202 has been inspected and repaired, it can be pushed into the slot 201 and then the hand-tightening bolt 303 can be tightened to fix it. At the same time, the elastic force of the spring 302 will also push the limit block 304 upward, which can reduce the possibility of the hand-tightening bolt 303 loosening and improve the disassembly and assembly efficiency. The improved device does not require picking up the diaphragm absorbing material for testing, improving efficiency while providing higher accuracy.
