Description

Technical Field

[0001] This utility model relates to the field of sock performance testing technology, and in particular to a sock performance testing device that simulates walking. Background Technology

[0002] Socks are a type of clothing worn on the feet. They are necessities in people's daily lives and are also consumables. When socks are worn, they tightly wrap around the feet. Since people move through their feet, friction usually occurs between the socks and the inside of the shoes. Over time, this can cause the socks to become thin and eventually become damaged. Therefore, the abrasion resistance of socks is usually tested during the sock production process.

[0003] Current methods for testing the abrasion resistance of socks rely on manual operation. This involves placing socks one by one on a foot model and manually rubbing them against a surface similar to shoe material to evaluate the abrasion resistance of the socks. This testing method is not only time-consuming and lengthy, but also increases the workload of the testers, resulting in low overall work efficiency. Furthermore, it cannot simulate the movement of walking, which is the main dynamic process during actual wear of socks, such as walking. Therefore, existing testing methods cannot accurately reflect the abrasion resistance of socks in real-world usage scenarios. Hence, we have introduced a new sock performance testing device that simulates walking. Utility Model Content

[0004] The main objective of this invention is to provide a sock performance testing device that simulates walking, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A sock performance testing device simulating walking includes a frame with a road base on its platform. A connecting frame is fixedly connected to the upper front of the frame, and a motor is fixedly installed at the left end of the connecting frame. The output end of the motor is connected to a double-crankshaft via a coupling. The double-crankshaft is connected to two thigh rods via pins. The ends of the two thigh rods away from the double-crankshaft are each connected to a calf rod via pins. A combined sample is placed at the ends of the two calf rods away from the thigh rods. The rear ends of the two calf rods are connected to connecting rods via pins. Pulleys are provided at the upper left and upper right ends of the frame, and connecting ropes are slidably connected inside the two pulleys. A weight is provided at the lower end of each connecting rope, and the ends of the two connecting ropes away from the weights are fixedly connected to the two connecting rods respectively. A control panel is provided at the lower front of the frame.

[0007] Preferably, the upper surface of the road surface base is a replaceable wear-resistant material layer, and the wear-resistant material layer includes sandpaper, rubber, or fabric to simulate different road surface friction characteristics.

[0008] By adopting the above technical solution, different walking surfaces such as gravel roads, rubber tracks, or carpets can be simulated by changing different abrasion-resistant material layers, thereby more comprehensively testing the abrasion resistance of socks.

[0009] Preferably, the motor is a variable frequency motor, and its speed can be adjusted within the range of 0-1000 rpm.

[0010] By adopting the above technical solution, the stress and friction experienced by socks at different speeds, such as slow walking, normal walking, and fast walking, can be simulated by adjusting the motor speed, which helps to evaluate the durability of socks in various sports scenarios.

[0011] Preferably, the double-crankshaft is made of high-strength alloy steel.

[0012] By adopting the above technical solution, wear and deformation can be prevented during frequent movement, ensuring the reliability and stability of the testing device.

[0013] Preferably, an angle sensor is provided at the connection between the thigh bar and the calf bar.

[0014] By adopting the above technical solution, the angle sensor can accurately record the motion posture of the leg simulation mechanism. This data is very important for analyzing the force and performance changes of socks under different walking postures.

[0015] Preferably, the connecting rope is a high-strength nylon rope, and the counterweight includes multiple counterweights of different weights.

[0016] By adopting the above technical solution, the high-strength nylon rope has high strength and wear resistance, can withstand the tension of the hammer, ensure the normal operation of the testing device, and extend the service life of the connecting rope.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By combining a motor, double crankshaft, thigh bar, connecting rod, and calf bar, the movement of the legs during human walking can be simulated relatively accurately. This simulation allows the socks to experience stress and friction similar to actual wearing and walking during the test, thus more accurately evaluating the durability of the socks. For example, in actual walking, the flexion and extension movements of the human leg will cause the socks to be stretched, compressed, and rubbed in different parts. Through the linkage of the mechanical structure, these movements can be reproduced, simulating human walking and making the test results more practically meaningful.

[0019] 2. Road surface bases can be used to simulate different walking surfaces, such as rough ground and smooth ground. By changing the different abrasion-resistant materials on the upper surface of the road surface base, the abrasion resistance of socks under different friction environments can be tested. For example, for outdoor hiking socks, a rougher road surface base can be set up to test the durability of the socks under different environments. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Please refer to Figures 1-3. This utility model provides a technical solution:

[0028] A sock performance testing device simulating walking includes a frame 1. A road base 2 is provided on the platform of the frame 1. A connecting frame 3 is fixedly connected to the upper front end of the frame 1. A motor 4 is fixedly installed on the left end of the connecting frame 3. The output end of the motor 4 is connected to a double-crankshaft 5 through a coupling. The double-crankshaft 5 is connected to two thigh rods 6 through axle pins. The ends of the two thigh rods 6 away from the double-crankshaft 5 are each connected to a calf rod 7 through axle pins. A combined sample 8 is provided at the ends of the two calf rods 7 away from the thigh rods 6. The rear ends of the two calf rods 7 are each connected to a connecting rod 9 through axle pins. Pulleys 10 are provided at the upper left and upper right ends of the frame 1. Connecting ropes 11 are slidably connected inside the two pulleys 10. A weight 12 is provided at the lower end of the two connecting ropes 11. The ends of the two connecting ropes 11 away from the weight 12 are respectively fixedly connected to the two connecting rods 9. A control panel 13 is provided at the lower front end of the frame 1.

[0029] In this embodiment, the upper surface of the road base 2 is a replaceable wear-resistant material layer, which includes sandpaper, rubber, or fabric to simulate different road surface friction characteristics. The motor 4 is a variable frequency motor, and its speed can be adjusted within the range of 0-1000 rpm. The double crankshaft 5 is made of high-strength alloy steel.

[0030] The above scheme allows for the simulation of different walking surfaces, such as gravel roads, rubber tracks, or carpets, by replacing different wear-resistant material layers on the road surface base 2. This enables a more comprehensive test of the socks' abrasion resistance. By adjusting the speed of the motor 4, the stress and friction experienced by the socks at different speeds, from slow walking and normal walking to fast walking, can be simulated, which helps to evaluate the durability of the socks in various sports scenarios. In addition, the double crankshaft 5 is made of high-strength alloy steel, which can prevent wear and deformation during frequent movement, ensuring the reliability and stability of the testing device.

[0031] In this embodiment, an angle sensor is provided at the connection between the thigh bar 6 and the calf bar 7, the connecting rope 11 is a high-strength nylon rope, and the weight 12 includes multiple counterweights of different weights.

[0032] Through the above scheme: the angle sensor can accurately record the movement posture of the leg simulation mechanism. This data is very important for analyzing the stress and performance changes of the socks under different walking postures. In addition, the high-strength nylon rope has high strength and wear resistance, and can withstand the tension of the weight 12, ensuring the normal operation of the testing device and extending the service life of the connecting rope 11. Furthermore, the pressure exerted on the socks by people of different weights can be simulated by adding or removing counterweights.

[0033] It should be noted that this utility model is a sock performance testing device that simulates walking. During use, the sock to be tested is fixed on the combined sample 8, and the motor 4 is started. The output end of the motor 4 transmits power to the double-crankshaft 5 through a coupling. The motor 4 can be set to different speeds according to the testing requirements, thereby controlling the simulated walking speed. The double-crankshaft 5 begins to rotate under the drive of the motor 4. The double-crankshaft 5 is connected to two thigh rods 6 through axle pins. The rotational motion of the double-crankshaft 5 drives the thigh rods 6 to reciprocate. The oscillation of the thigh rods 6 is transmitted to the calf rods 7 through the axle pins. The calf rods 7 also perform corresponding oscillations under the drive of the thigh rods 6. In this way, the coordinated movement of the thigh rods 6 and the calf rods 7 simulates the leg movement during human walking. The flexion and extension movements of the leg are controlled by connecting rods 9 at the rear ends of the two lower leg rods 7 via axle pins. The connecting rods 9 act similarly to the hamstrings in the human body, ensuring the continuity of leg movement. When the lower leg rods 7 move, the weights 12 exert a pulling force on the lower leg rods 7 through the action of the connecting ropes 11 and pulleys 10. This pulling force simulates the pressure exerted by the feet on the socks when the human body walks. Different weights of weights 12 can simulate the pressure exerted on the socks by people of different weights. Furthermore, by changing the different wear-resistant materials on the upper surface of the road base 2, the wear resistance of the socks under different friction environments can be tested. The entire sock performance testing device, through the linkage of the mechanical structure, can simulate the human walking motion, making the test results more practical and thus more accurately evaluating the durability of the socks.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
