Description

Technical Field

[0001] This utility model belongs to the field of carpet testing technology, specifically relating to a carpet electrostatic testing device. Background Technology

[0002] Carpets are floor coverings made from natural fibers such as cotton, linen, wool, silk, and grass yarn, or chemically synthesized fibers, through hand or machine processes of weaving, tufting, or spinning. Humans and objects constantly rub against carpets, and due to the material of carpets, static electricity is generated during this friction; therefore, static electricity testing of carpets is necessary.

[0003] In existing carpet static electricity testing devices, when testing the static electricity generated by carpet friction, a constant pressure is applied to the carpet surface for friction. However, the friction of a human body walking is not easy to imitate, leading to inaccuracies in the test. Utility Model Content

[0004] The purpose of this invention is to provide a carpet electrostatic detection device with a simple structure that can simulate the friction state of two types of carpets to closely simulate the friction brought about by walking on the carpet. It has high accuracy, strong practicality, and is suitable for widespread application.

[0005] This utility model provides the following technical solution: a carpet electrostatic detection device, including a base, with upright support frames fixed on the front and rear sides of the base, a drive platform fixed in the middle of the base and the drive platform having a through connecting plate, an electric telescopic rod fixed below the drive platform by a bracket, a lifting rod connected to the output end of the electric telescopic rod, the lifting rod being connected to the middle of the connecting plate via a first rotating shaft, and spring rods installed between the two sides of the connecting plate and the lifting rod via a second rotating shaft, the two spring rods being symmetrical to each other;

[0006] A top plate is fixed between the two support frames, and a pressure plate is provided between the two support frames below the top plate. Symmetrical columns are fixed on both sides of the upper end of the connecting plate. The columns are located on both sides of the middle part of the pressure plate and are connected to it through a connecting shaft.

[0007] The drive platform is fixedly provided with side plates on both sides of the connecting plate. The two side plates are provided with through holes near the sides, and a top rod is slidably provided at the through holes.

[0008] Preferably, the upper two sides of the pressure plate have an arc-shaped cross-section, and the upper end of the pressure plate is covered with a friction surface.

[0009] Preferably, a control seat is fixedly mounted on the support frame, the control seat is connected to the circuit signal of the electric telescopic rod, and a measuring capacitor is provided on the pressure plate.

[0010] Preferably, the top rod is located on one side of the centerline of the connecting plate, and the height of the top rod is such that the carpet can be clamped between the friction surface and the top plate.

[0011] The beneficial effects of this utility model are: simple structure, ability to simulate the friction states of two types of carpets, closely mimicking the friction generated when walking on a carpet, high precision, and strong practicality, as detailed below:

[0012] (1) This utility model is equipped with a pressure plate. When detecting static electricity of the carpet, the carpet is passed through the pressure plate and the top plate by the pulling mechanism. At this time, the electric telescopic rod operates and pushes the connecting plate upward, causing the pressure plate to rise. The friction surface on the pressure plate applies pressure to the carpet. When the carpet passes by, the measuring capacitor on the pressure plate detects the static electricity generated by friction. This detection speed is relatively fast. When the friction static electricity generated during simulated walking is detected, the top rod can be inserted to change the rising mode of the pressure plate.

[0013] (2) This utility model is equipped with a connecting plate. According to the friction generated by the human body walking on the carpet, the friction distance is small, and the friction pressure will increase and then decrease. After the top rod is inserted, the electric telescopic rod lifts the connecting plate. Under the action of the spring rod, the connecting plate and the pressure plate connected to it are parallel to the top plate, clamping the carpet. When the electric telescopic rod continues to lift, it squeezes the top rod, causing the connecting plate to tilt. At this time, the pressure plate deflects. As the tilt of the connecting plate intensifies, the pressure plate tilts and the carpet slides slightly. The force applied to the carpet at this point increases to simulate the effect of the human body stepping on the carpet. After squeezing, the electric telescopic rod pulls the pressure plate down and releases the carpet. At this time, the carpet pulling mechanism pulls the carpet to the next position to align with the pressure plate for the next operation. Attached Figure Description

[0022] The structural features of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] See Figure 1-3 A carpet electrostatic detection device includes a base 1, with upright support frames 2 fixedly mounted on the front and rear sides of the base 1. A drive platform 4 is fixedly mounted on the base 1 in the middle of the two support frames 2. A through connecting plate 5 is mounted on the drive platform 4. When not in use, the connecting plate 5 is locked inside the drive platform 4. An electric telescopic rod 6 is fixedly mounted below the drive platform 4 by a bracket. The output end of the electric telescopic rod 6 is connected to a lifting rod 13, which provides an upward thrust. The lifting rod 13 is connected to the middle of the connecting plate 5 through a first rotating shaft 14. Spring rods 15 are installed on both sides of the connecting plate 5 and between the lifting rod 13 through a second rotating shaft 16. The two spring rods 15 are symmetrical to each other and keep the connecting plate 5 horizontal when it is not subjected to external force.

[0024] See Figure 1 , 4A top plate 11 is fixed between two support frames 2, and a pressure plate 8 is located below the top plate 11 between the two support frames 2. The carpet is rubbed between the top plate 11 and the pressure plate 8. The upper two sides of the pressure plate 8 have an arc-shaped cross section, which allows for a larger contact area when deflected. A friction surface 10 is laid on the upper end of the pressure plate 8, which simulates the friction of the sole of a shoe against the carpet. Symmetrical columns 7 are fixed on both sides of the upper end of the connecting plate 5. The columns 7 are located on both sides of the middle of the pressure plate 8 and are connected to it through a connecting shaft 9. Side plates 12 are fixed on both sides of the connecting plate 5. The two side plates 12 have through holes near the sides. A top rod 17 is slidably installed in the through holes. The top rod 17 is located on one side of the center line of the connecting plate 5. The height of the top rod 17 is sufficient to allow the carpet to be clamped between the friction surface 10 and the top plate 11. After the top rod 17 is manually inserted, the connecting plate 5 moves to the top rod 17 and deflects, causing the pressure plate 8 to deflect, thus simulating stepping on the carpet.

[0025] See Figure 1 The support frame 2 is fixedly equipped with a control seat 3, which is connected to the circuit signal of the electric telescopic rod 6. The pressure plate 8 is equipped with a measuring capacitor. The control seat 3 controls the two movement states of the electric telescopic rod 6 and displays the measurement reading of the measuring capacitor.

[0026] This utility model of carpet electrostatic detection device has a simple structure and can simulate the friction state of two types of carpets to closely simulate the friction brought about by walking on the carpet. It has high accuracy, strong practicality, and is suitable for widespread application.

[0027] For specific usage, please refer to... Figure 1-3 When detecting static electricity in the carpet, the carpet is pulled through the space between the pressure plate 8 and the top plate 11 via a pulling mechanism. At this time, the electric telescopic rod 6 operates, pushing the connecting plate 5 upwards and causing the pressure plate 8 to rise. The friction surface 10 on the pressure plate 8 applies pressure to the carpet. As the carpet passes over it, the measuring capacitor on the pressure plate 8 detects the static electricity generated by friction. This detection method is relatively fast. When simulating the static electricity generated by walking on the carpet, the friction distance is small, and the friction pressure gradually increases and then decreases. After inserting the top rod 17, the electric telescopic rod 6 lifts the connecting plate 5. Under the action of the spring rod 15... At this time, the connecting plate 5 and its connected pressure plate 8 are parallel to the top plate 11, clamping the carpet. As the electric telescopic rod 6 continues to rise, it squeezes the top rod 17, causing the connecting plate 5 to tilt. At this time, the pressure plate 8 deflects. As the tilt of the connecting plate 5 intensifies, the pressure plate 8 slightly slides against the carpet, increasing the force applied to the carpet at that point to simulate the effect of a person stepping on the carpet. After squeezing, the electric telescopic rod 6 pulls the pressure plate 8 down, releasing the carpet. The carpet pulling mechanism pulls the carpet to the next position aligned with the pressure plate 8 for the next operation. The two movement states of the electric telescopic rod 6 are controlled by the control seat 3, and the measurement reading of the measuring capacitor is displayed.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
