Description

Technical Field

[0001] This utility model relates to the field of resistance testing technology, specifically to a surface resistance testing device for non-metallic components. Background Technology

[0002] Non-metallic materials are mostly high-molecular polymers, and a significant characteristic of them is their susceptibility to static electricity buildup. When this static charge accumulates beyond a certain threshold, electrostatic discharge (ESD) can occur. To prevent ESD caused by static charge buildup during the use of non-metallic materials, it is necessary to select appropriate materials based on their surface resistance when using them in flammable and explosive environments. This necessitates accurate measurement of the material's surface resistance.

[0003] For example, a portable insulation resistance testing device disclosed in Chinese Patent Publication No. CN219695241U includes a protective shell, a testing body fixedly connected to the inner side of the protective shell, an extension line fixedly connected to the outer surface of the testing body, and a docking block fixedly connected to the end of the extension line away from the testing body. This device has the following technical problems:

[0004] When the docking block needs to test the surface resistance of non-metallic parts, the extension cable installed on the test body will be pulled away from the test body by the docking block. After the surface battery test of the non-metallic parts is completed, the extension cable and the docking block cannot be stored, which makes the docking block easily damaged by accidental collision when the test body is taken out. Utility Model Content

[0005] Therefore, this utility model provides a surface resistance testing device for non-metallic components to solve the problem that extension wires and mating blocks cannot be stored in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A surface resistance testing device for non-metallic components includes a resistance tester body.

[0008] The resistance tester body has connecting wires on both the left and right sides, and a test head is connected to one side of each connecting wire.

[0009] The resistance tester body is equipped with protective devices on its left and right sides to protect the connecting wires and test head.

[0010] The protective device includes a lifting block for guiding the connecting line, and a limiting plate for limiting the lifting block, wherein the lifting block moves up and down inside the limiting plate.

[0011] Furthermore, L-shaped grooves for limiting the positioning plate are provided on both the left and right sides of the resistance tester body, and threaded holes are machined on both the left and right sides of the resistance tester body.

[0012] Furthermore, a bolt is installed at the lower center of the limiting plate to fix the limiting plate in conjunction with a threaded hole; a magnetic block is installed at the front and rear ends of the upper part of the limiting plate; and a magnetic block is installed at the front and rear ends of the lower part of the limiting plate.

[0013] Furthermore, a limiting block is installed on the upper end of the limiting plate, and a slot for limiting the test head is provided above the limiting block. A bolt for limiting the limiting block is installed on the upper end of the limiting plate.

[0014] Furthermore, the inner walls at both ends of the limiting plate are equipped with sliders for limiting the lifting block, and the inner wall at the upper end of the limiting plate is equipped with a first roller for limiting the connecting line.

[0015] Furthermore, a handle is installed on one side of the lifting block, and sliding grooves for sliding of the slider are opened at both ends of the lifting block. Magnetic block three is installed at both ends of one side of the lifting block, and magnetic block three is magnetically attracted to magnetic block one and magnetic block two respectively.

[0016] Furthermore, the middle part of the lifting block is machined with a first through hole, a second through hole, a third through hole and a fourth through hole for the connecting wire to pass through, and the lower end of the lifting block is equipped with a second roller and a third roller for cooperating with the first roller to guide the connecting wire.

[0017] This utility model has the following advantages:

[0018] When the resistance tester body performs resistance testing on the surface of a non-metallic component, while pulling the test head, hold the handle and pull the lifting block upwards, causing magnetic block three and magnetic block one to be magnetically attracted. At this time, the connecting wire is pulled out from inside the limiting plate, making it easier for the test head to contact the surface of the non-metallic component for resistance testing. After the resistance test is completed, pull the handle downwards, simultaneously moving the lifting block downwards, so that the connecting wire is retracted into the limiting plate for protection. When magnetic block two and magnetic block three are magnetically attracted, the test head is inserted into the slot cavity, thus completing the storage of the connecting wire and the test head.

[0031] Please see Figures 1-6 This utility model provides a surface resistance testing device for non-metallic components, including a resistance tester body 100.

[0032] The resistance tester body 100 is connected to the left and right sides by connecting wires 110, and a test head 111 is connected to one side of the connecting wires 110 to facilitate resistance testing of the surface of non-metallic parts.

[0033] The resistance tester body 100 is equipped with protective devices 200 on its left and right sides to protect the connecting wire 110 and the test head 111. The protective devices 200 are detachable. The protective devices 200 include a lifting block 210 for guiding the connecting wire 110 and a limiting plate 220 for limiting the lifting block 210. The lifting block 210 moves up and down inside the limiting plate 220 to facilitate the removal of the connecting wire 110 and the test head 111 for resistance testing.

[0034] The resistance tester body 100 has L-shaped grooves 120 on both the left and right sides for limiting the position plate 220. Threaded holes 130 are machined on both the left and right sides of the resistance tester body 100, and the threaded holes 130 are machined in the middle of the lower end of the resistance tester body 100.

[0035] The lower middle part of the limiting plate 220 is equipped with a bolt 221 for fixing the limiting plate 220 with the threaded hole 130. The limiting plate 220 is a U-shaped rod, and the two ends of the U-shaped rod are connected with crossbars so that the two sides of the limiting plate 220 can slide into the groove of the L-shaped slide groove 120.

[0036] A magnetic block 222 is fixedly installed at the front and rear ends of the upper part of the limiting plate 220, and a magnetic block 223 is fixedly installed at the front and rear ends of the lower part of the limiting plate 220. The setting of magnetic blocks 222 and 223 facilitates the positioning of the lifting block 210. A limiting block 224 is installed at the upper end of the limiting plate 220. A slot 225 for limiting the test head 111 is opened on the upper part of the limiting block 224. When the lifting block 210 is at the lower end of the limiting plate 220, the lower end of the test head 111 is inserted into the slot 225. A bolt 226 for limiting the limiting block 224 is installed at the upper end of the limiting plate 220. A threaded hole is opened on one side of the limiting block 224. After the bolt 226 is screwed into the threaded hole on the limiting block 224, the limiting block 224 is fixed.

[0037] The inner walls of the front and rear ends of the limiting plate 220 are fixedly installed with sliders 227 for limiting the lifting block 210, and the inner wall of the upper end of the limiting plate 220 is installed with a first roller 228 for limiting the connecting line 110.

[0038] A handle 211 is installed on one side of the lifting block 210, and the handle 211 is located outside the limiting plate 220, which facilitates the control of the lifting block 210 to move up and down. The front and rear ends of the lifting block 210 are provided with slide grooves 218 for the slider 227 to slide. When the lifting block 210 is installed, the slider 227 and the slide groove 218 are aligned, so that the lifting block 210 slides from the upper end of the limiting plate 220 to the lower end of the limiting plate 220.

[0039] Magnetic blocks 219 are installed at both ends of one side of the lifting block 210. Magnetic blocks 219 are magnetically attracted to magnetic blocks 222 and 223 respectively. When the resistance tester body 100 is in use, the lifting block 210 is at the upper end of the limiting plate 220, and magnetic blocks 219 and 222 are magnetically attracted, so the lifting block 210 cannot move. When the resistance tester body 100 is finished using and the connecting wire 110 needs to be stored, the lifting block 210 moves to the lower end of the limiting plate 220, and magnetic blocks 219 and 223 are magnetically attracted. At this time, the test head 111 is stuck in the slot 225.

[0040] The lifting block 210 consists of two symmetrical square blocks, which are fixed together by hexagonal socket head cap screws. The middle of the lifting block 210 is machined with a first through hole 212, a second through hole 213, a third through hole 214, and a fourth through hole 215 for the connecting wire 110 to pass through. The lower end of the lifting block 210 is equipped with a second roller 216 and a third roller 217 for guiding the connecting wire 110 in conjunction with the first roller 228. The connecting wire 110 passes from the upper end of the first through hole 212 into the lower end of the cavity of the first through hole 212, and then passes from the lower end of the second roller 216 into the cavity of the second through hole 213. Subsequently, the connecting wire 110 passes from the upper end of the first roller 228 down into the cavity of the third through hole 214. The connecting wire 110 passes from the lower end of the third roller 217 into the cavity of the fourth through hole 215, and finally enters the middle of the limiting block 224, so that the test head 111 is inserted into the slot of the slot 225.

[0041] When the resistance tester body 100 performs a resistance test on the surface of a non-metallic component, while pulling the test head 111, the handle 211 is held to lift the lifting block 210 upwards, causing the magnetic block 3 219 and the magnetic block 1 222 to be magnetically attracted. At this time, the connecting wire 110 is pulled out from inside the limiting plate 220, making it easier for the test head 111 to contact the surface of the non-metallic component for resistance testing. After the resistance test is completed, the handle 211 is pulled downwards, simultaneously causing the lifting block 210 to move downwards, so that the connecting wire 110 is retracted into the limiting plate 220 for protection. When the magnetic block 223 and the magnetic block 3 219 are magnetically attracted, the test head 111 is inserted into the slot of the slot 225, thus completing the storage of the connecting wire 110 and the test head 111.

[0042] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
