Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a testing device for the safety performance of an electric heating pad. Background Technology

[0002] Electric heating pads are a common household appliance widely used in physical therapy, health care, and comfort heating. Their main function is to convert electrical energy into heat energy through electric heating elements to provide warmth and comfort. However, because electric heating pads involve electrical safety and heat energy control, it is necessary to use testing equipment to test their safety performance.

[0003] Existing testing equipment typically requires manual inspection of the safety performance of electric heating pads during installation and use. It can only perform simple tests on tensile strength and cannot effectively fix the electric heating pad during the testing process, resulting in low work efficiency and adverse effects on users. To address the shortcomings of existing technology, we propose a safety performance testing device for electric heating pads. Utility Model Content

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In this utility model, the two sides of the electric heating pad are clamped by the first clamp and the second clamp.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Example 1, as Figures 1-5 As shown, an electric heating pad safety performance testing device includes a testing platform 1. Inside the testing platform 1, a first clamp 4 and a second clamp 10 are provided. The operator clamps and fixes the two sides of the electric heating pad by using the first pressure plate 6 and the second pressure plate 11 respectively. Then, the hook at the bottom of the tension gauge 12 (in the prior art) is connected to the fixing ring 9. The winding shaft 17 is rotated by the third motor 16 to wind up the traction rope 13. At the same time, the first base 8 is pulled to slide to the left, which facilitates the operator to test the tensile performance of the electric heating pad. During the stretching process, the tension gauge 12 facilitates the operator to measure the magnitude of the tension. The roller 14 supports and limits the traction rope 13 to prevent it from rubbing against the edge of the testing platform 1.

[0023] Example 2, as Figures 1-5 As shown, an electric heating pad safety performance testing device, during the stretching process, the operator starts the second motor 3, which controls the first clamp 4 to rotate back and forth, with a rotation angle not exceeding 360 degrees, to twist the electric heating pad, facilitating the operator's testing of the electric heating pad's torsion performance. After the second motor 3 stops working, the first motor 2 controls the threaded rod 22 to rotate, thereby controlling the bracket 20 to slide inside the testing platform 1. At the same time, the cylinder 21 controls the roller 28 to move downward, and the roller 28 squeezes the electric heating pad, facilitating the operator's testing of the electric heating pad's abrasion resistance.

[0024] It should be noted that this utility model is a safety performance testing device for an electric heating pad. During use, the operator clamps both sides of the electric heating pad using the first clamp 4 and the second clamp 10. Then, the hook at the bottom of the tension gauge 12 is connected to the fixing ring 9. One end of the traction rope 13 is connected to the other end of the tension gauge 12, and the other end of the traction rope 13 is fixed to the winding shaft 17. The traction rope 13 is then secured inside the groove on the inner wall of the roller 14. When the third motor 16 controls the winding shaft 17 to rotate, it winds up the traction rope 13, pulling the first... The base 8 slides to the left to test the tensile strength of the electric heating pad. The tension gauge 12 allows the staff to observe the tension of the traction rope 13. The connecting block 5 allows the staff to install and remove the first clamp 4. When the staff needs to adjust the height of the bracket 20, the pin 25 is pulled out, and the bracket 20 is lifted up to the required height. Then the pin 25 is inserted into the extension rod 23 and the inner wall of the bracket 20 to fix it, thus completing the height adjustment of the bracket 20, which greatly improves the testing efficiency.
