Description

Technical Field

[0001] This utility model relates to the field of silver fiber fabric technology, specifically to a device for testing the conductivity of silver fiber fabric. Background Technology

[0002] Silver fibers, obtained by coating nylon fibers with a silver layer, are used to make electromagnetic shielding fabrics. Due to their excellent radiation protection performance, these fabrics are widely used in maternity radiation protection clothing. The electromagnetic shielding principle of radiation protection clothing mainly relies on the closed circuit formed by the silver-plated fibers. The conductivity directly affects the quality of electromagnetic shielding performance. The thickness of the silver-plated layer on the surface of the nylon fibers is the key to determining the resistivity of the silver-plated fibers. Generally speaking, there is a certain deviation in the silver-plated layer on the fiber surface. Radiation protection fabrics woven from substandard silver-plated fibers will inevitably affect the radiation protection performance of the electromagnetic shielding fabric. Therefore, before making radiation protection clothing, it is necessary to test the conductivity of the silver fiber fabric.

[0003] A search revealed a silver fiber resistance testing device published in China on July 16, 2014, with patent publication number CN103926464A. The device is described as follows: it includes a base, a test frame mounted on the base, two connecting columns on the test frame for supporting and guiding the silver fiber to be tested, and pulling components at both ends of the silver fiber to be tested that apply an initial tension to both ends of the fiber to be tested, thereby horizontally straightening the silver fiber placed between the two connecting columns. A testing instrument for testing the resistance of this portion of the silver fiber is connected to the silver fiber between the two connecting columns.

[0004] Although the aforementioned existing technical solution can measure quickly, has a wide testing range, and effectively ensures the radiation protection performance of silver fiber fabric, the device uses two counterweights to stretch the silver fiber, which makes the silver fiber fabric prone to skew on the device and reduces the stability of the device. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a conductivity testing device for silver fiber fabrics, thereby solving the problem mentioned in the background technology that silver fiber fabrics are prone to skew on the device, reducing the stability of the device.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a conductivity testing device for silver fiber fabric, comprising a base and two upper clamping plates. A control groove is formed at the top of the base, and a bidirectional threaded rod is rotatably connected inside the control groove. One end of the bidirectional threaded rod passes through the control groove and is connected to a rotating handle. Two mating threaded parts are threaded onto the bidirectional threaded rod, and the tops of both threaded parts pass through the control groove and are connected to connecting seats. Lower clamping plates are fixedly connected to the tops of both connecting seats. Two through holes are formed at positions far apart on the two lower clamping plates. The two upper clamping plates are respectively located above the two lower clamping plates. Two sliding rods that are slidably connected to the through holes are fixedly connected to the bottom ends of the two upper clamping plates. A connecting plate is fixedly connected to the bottom ends of the two sliding rods. A spring is provided between the connecting plate and the lower clamping plates. A 7-shaped plate is fixedly connected to the top of the base, and a testing instrument is mounted on the top of the 7-shaped plate. The testing instrument has two wires, and one end of each wire has a fixing block connected to the upper clamping plate. A probe is mounted on the fixing block.

[0009] By employing the above technical solution, the two upper clamping plates are pulled respectively, placing the two ends of the silver fiber fabric between the upper and lower clamping plates. At this time, the spring pushes the connecting plate, sliding rod, and upper clamping plates to move, thereby making the upper and lower clamping plates cooperate to clamp and fix the silver fiber fabric. Then, rotating the rotating handle drives the bidirectional threaded rod to rotate, which drives the two threaded parts to move, thereby moving the connecting seat, lower clamping plate, and upper clamping plate. This causes the equipment to move the two ends of the silver fiber fabric, thus achieving the purpose of stretching the silver fiber fabric flat. At this time, the two probes are pressed tightly against the two ends of the silver fiber fabric. At this time, the conductivity of the silver fiber fabric can be detected by testing instruments through the two probes, thereby preventing the silver fiber fabric from tilting and improving the stability of the equipment.

[0010] Optionally, anti-slip pads are provided at the bottom of the two upper clamping plates and at the top of the two lower clamping plates.

[0011] By adopting the above technical solution, the anti-slip mat is used to increase the friction between the silver fiber fabric and the equipment, thereby improving the stability of the equipment.

[0012] Optionally, the top of the base is provided with a scale, and each of the two connecting seats is fixedly connected with a pointer that matches the scale.

[0013] By adopting the above technical solution, the scale and pointer work together to conveniently display the current position of the two connectors, thereby facilitating the determination of the distance between the two probes and indicating the length of the fabric being tested.

[0014] Optionally, both of the fixing blocks are provided with corrugated tubes at their top ends, and the wires are located inside the corrugated tubes.

[0015] By adopting the above technical solution, the corrugated pipe is used to support the connection between the wire and the fixing block, thereby preventing the wire from bending excessively and reducing the probability of wire damage.

[0016] Optionally, each of the four corners of the top of the base is provided with a rotating seat, and a lifting handle is rotatably connected to the four rotating seats.

[0017] By adopting the above technical solution, the lifting handle is used to facilitate personnel to hold and move the equipment, thereby improving the convenience of the equipment.

[0018] (III) Beneficial Effects

[0019] In summary, this utility model has at least one of the following beneficial technical effects:

[0020] This silver fiber fabric conductivity testing device works by pulling two upper clamping plates, placing the two ends of the silver fiber fabric between the upper and lower clamping plates respectively. A spring then pushes the connecting plate, sliding rod, and upper clamping plates to move, causing the upper and lower clamping plates to engage and clamp the silver fiber fabric. Rotating the rotating handle drives a bidirectional threaded rod, which in turn moves two threaded components, thereby moving the connecting seat, lower clamping plate, and upper clamping plate. This causes the device to move the two ends of the silver fiber fabric, stretching it flat. Two probes are then positioned close to the two ends of the silver fiber fabric, allowing testing instruments to detect its conductivity. This method prevents the silver fiber fabric from tilting and improves the stability of the device. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Reference Figures 1-4 A conductivity testing device for silver fiber fabric includes a base 1 and two upper clamping plates 2. A control groove is formed at the top of the base 1, and a bidirectional threaded rod 3 is rotatably connected inside the control groove. One end of the bidirectional threaded rod 3 passes through the control groove and is connected to a rotating handle 4. Two mating threaded parts 5 are threaded onto the bidirectional threaded rod 3. The tops of both threaded parts 5 pass through the control groove and are connected to connecting seats 6. Lower clamping plates 7 are fixedly connected to the tops of both connecting seats 6. Two through holes are formed at positions far apart on the two lower clamping plates 7. The two upper clamping plates 2 are located above the two lower clamping plates 7. Two sliding rods 8, which are slidably connected to the through holes, are fixedly connected to the bottom ends of the two upper clamping plates 2. Connecting plates 9 are fixedly connected to the bottom ends of the two sliding rods 8. A spring 10 is provided between the connecting plate 9 and the lower clamping plates 7. A 7-shaped plate 11 is fixedly connected to the top of the base 1. A testing instrument 12 is mounted on the top of the 7-shaped plate 11. Two wires 13 are provided on the testing instrument 12. One end of each conductor 13 is equipped with a fixing block 14 connected to the upper clamping plate 2. The fixing block 14 is equipped with a probe 15. Pulling the two upper clamping plates 2 respectively places the two ends of the silver fiber fabric between the two upper clamping plates 2 and the lower clamping plate 7. At this time, the spring 10 pushes the connecting plate 9, the sliding rod 8 and the upper clamping plate 2 to move, so that the upper clamping plate 2 and the lower clamping plate 7 cooperate to clamp and fix the silver fiber fabric. At this time, rotating the rotating handle 4 drives the bidirectional threaded rod 3 to rotate. The bidirectional threaded rod 3 drives the two threaded parts 5 to move, thereby driving the connecting seat 6, the lower clamping plate 7 and the upper clamping plate 2 to move. This causes the equipment to move the two ends of the silver fiber fabric, thereby achieving the purpose of stretching the silver fiber fabric flat. At this time, the two probes 15 are respectively close to the two ends of the silver fiber fabric. At this time, the test instrument 12 can be used to detect the conductivity of the silver fiber fabric through the two probes 15, thereby avoiding the silver fiber fabric from tilting and improving the stability of the equipment.

[0029] Reference Figures 1-4Anti-slip pads 16 are provided at the bottom of the two upper clamping plates 2 and at the top of the two lower clamping plates 7. The anti-slip pads 16 are used to increase the friction between the silver fiber fabric and the equipment, thereby improving the stability of the equipment.

[0030] Reference Figure 1 and Figure 2 The top of the base 1 is provided with a scale 17. Each of the two connecting seats 6 is fixedly connected with a pointer 18 that matches the scale 17. The scale 17 and the pointer 18 work together to conveniently display the current position of the two connecting seats 6, so as to facilitate the determination of the distance between the two probes 15 and thus indicate the length of the fabric being tested.

[0031] Reference Figure 1 and Figure 2 Both fixing blocks 14 have a corrugated tube 19 at their top ends. The wire 13 is located inside the corrugated tube 19. The corrugated tube 19 is used to support the connection between the wire 13 and the fixing block 14, so as to prevent the wire 13 from being bent excessively and reduce the probability of the wire 13 being damaged.

[0032] Reference Figure 1 The base 1 has four rotating seats at the top corners, and each of the four rotating seats is rotatably connected to a lifting handle 20. The lifting handle 20 is used to facilitate personnel to hold and move the equipment, thereby improving the convenience of the equipment.

[0033] In summary, the working principle and process of this silver fiber fabric conductivity testing device are as follows: First, pull the two upper clamping plates 2 respectively, placing both ends of the silver fiber fabric between the upper clamping plates 2 and the lower clamping plate 7. At this time, the spring 10 pushes the connecting plate 9, the sliding rod 8, and the upper clamping plate 2 to move, thus engaging the upper clamping plate 2 and the lower clamping plate 7 to clamp and fix the silver fiber fabric. Then, rotating the rotating handle 4 drives the bidirectional threaded rod 3 to rotate, which in turn moves the two threaded parts 5, thereby moving the connecting seat 6, the lower clamping plate 7, and the upper clamping plate 2. This causes the device to move both ends of the silver fiber fabric, achieving the purpose of stretching the silver fiber fabric flat. At this point, the two probes 15 are tightly attached to both ends of the silver fiber fabric, and it can then be used. The testing instrument 12 uses two probes 15 to detect the conductivity of the silver fiber fabric, thereby preventing the silver fiber fabric from tilting and improving the stability of the equipment. The anti-slip pad 16 is used to increase the friction between the silver fiber fabric and the equipment, thereby improving the stability of the equipment. The scale 17 and pointer 18 work together to easily display the current position of the two connecting seats 6, so as to facilitate the judgment of the distance between the two probes 15 and to indicate the length of the fabric being tested. The corrugated tube 19 is used to support the connection position of the wire 13 and the fixing block 14, thereby preventing the wire 13 from being excessively bent and reducing the probability of damage to the wire 13. The lifting handle 20 is used to facilitate personnel to hold and move the equipment, thereby improving the convenience of the equipment.

[0034] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
