Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0028] Please refer to Figures 1 to 3, the present utility model provides a new technical solution: a device for testing the electrical conductivity of a graphene functional conductive material, including a housing 1, a housing cover 2 is arranged on the upper side of the housing 1, a handle 3 is fixedly connected to the left side of the housing cover 2, locking blocks are arranged on the left sides of the housing 1 and the housing cover 2, and the housing 1 and the housing cover 2 are locked by the locking blocks. A connecting rotating shaft 4 is rotatably connected between the housing 1 and the housing cover 2, and the housing 1 and the housing cover 2 are rotatably connected through the connecting rotating shaft 4. A carrying rod 5 is arranged on the outer side of the housing 1, and the carrying rod 5 is rotatably connected to the front side and the rear side of the housing 1 respectively. A storage battery 6 is fixedly connected to the inside of the housing 1, a positive electrode 7 and a negative electrode 8 are fixedly connected to the upper side of the storage battery 6, and the positive electrode 7 and the negative electrode 8 are arranged front and back. Detection mechanisms are arranged on both the housing cover 2 and the storage battery 6, and the detection mechanism can test the electrical conductivity of the graphene material. The detection mechanism includes a support plate 9, a first spring 10, a mounting groove 11, a detector 12, a display screen 13, a pressing plate 14 and a second spring 15.

[0029] Furthermore, the support plate 9 is arranged on the upper side of the storage battery 6, the support plate 9 is arranged between the positive electrode 7 and the negative electrode 8, the upper side of the support plate 9 can be in contact with the test material, the first spring 10 is fixedly connected to the lower side of the support plate 9, and the lower end of the first spring 10 is fixedly connected to the upper side of the storage battery 6. The mounting groove 11 is opened on the lower side of the housing cover 2, the detector 12 is fixedly connected to the inside of the mounting groove 11, the display screen 13 is fixedly connected to the upper side of the housing cover 2, the lower end of the display screen 13 extends into the mounting groove 11, the display screen 13 is fixedly connected to the detector 12, and the display screen 13 can display the data detected by the detector 12. The pressing plate 14 is fixedly connected to the lower side of the detector 12, the lower side of the pressing plate 14 can be in contact with the test material, the second spring 15 is fixedly connected to the upper side of the pressing plate 14, and the upper end of the second spring 15 is fixedly connected to the detector 12. Both the pressing plate 14 and the second spring 15 are conductive materials, and the thrust of the second spring 15 is greater than the thrust of the first spring 10.

[0030] Further, when starting the test, first unlock the locking block. Then, open the housing cover 2 through the handle 3. The housing cover 2 will rotate around the connecting rotating shaft 4. As a result, the first spring 10 will change from the compressed state to the extended state, pushing the support plate 9 upward. Then, place the graphene material on the upper side of the support plate 9. After that, pull the handle 3 to close the housing cover 2. Then, the pressing plate 14 will contact the upper side of the graphene material. Since the pushing force of the second spring 15 is greater than that of the first spring 10, the graphene material will be pressed to move downward until the lower side of the material contacts the positive electrode 7 and the negative electrode 8. Only then will the second spring 15 start to change to the compressed state. At this time, the storage battery 6, the positive electrode 7, the negative electrode 8, and the graphene material form a circuit. At the same time, the pressing plate 14 contacts the upper side of the graphene material. Through the conductivity of the pressing plate 14 and the second spring 15, the current of the graphene material will be transmitted to the detector 12. Then, the detector 12 will detect the current and obtain the result data. Finally, the result data will be displayed on the display screen 13.

[0031] Further, after completing the test, pull the handle 3 to open the housing cover 2. Then, the graphene material is no longer pressed by the pressing plate 14. The first spring 10 starts to reset from the compressed state. The first spring 10 will push the support plate 9 to reset. The support plate 9 pushes the graphene material upward. Then, the graphene material no longer contacts the positive electrode 7 and the negative electrode 8. At this time, touching the graphene material will not cause electric shock. Thus, it can be taken out. In this way, it is possible to avoid the staff from contacting the live part during the test, thereby avoiding the occurrence of electric shock when using the test device and improving the safety of the test device.

[0032] Working principle: When starting the test, first unlock the locking block. Then, open the housing cover 2 through the handle 3. The housing cover 2 will rotate around the connecting rotating shaft 4. As a result, the first spring 10 will change from the compressed state to the extended state, pushing the support plate 9 upward. Then, place the graphene material on the upper side of the support plate 9. After that, pull the handle 3 to close the housing cover 2. Then, the pressing plate 14 will contact the upper side of the graphene material. Since the pushing force of the second spring 15 is greater than that of the first spring 10, the graphene material will be pressed to move downward until the lower side of the material contacts the positive electrode 7 and the negative electrode 8. Only then will the second spring 15 start to change to the compressed state. At this time, the storage battery 6, the positive electrode 7, the negative electrode 8, and the graphene material form a circuit. At the same time, the pressing plate 14 contacts the upper side of the graphene material. Through the conductivity of the pressing plate 14 and the second spring 15, the current of the graphene material will be transmitted to the detector 12. Then, the detector 12 will detect the current and obtain the result data. Finally, the result data will be displayed on the display screen 13.

[0033] Further, after the test is completed, pull the handle 3 to open the shell cover 2. As a result, the graphene material is no longer pressed by the pressing plate 14. Then, the first spring 10 starts to reset from the compressed state. The first spring 10 will push the support plate 9 to reset, and the support plate 9 pushes the graphene material to move upward. As a result, the graphene material is no longer in contact with the positive electrode 7 and the negative electrode 8. At this time, touching the graphene material will not result in electric shock, and thus it can be taken out.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
