Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliance strength detection, and particularly relates to a household appliance compression strength detection device. BACKGROUND

[0002] At present, the quality and safety of household appliances are concerned in the booming household appliance industry. Compression strength, as a key indicator for measuring the structural reliability of household appliances, is directly related to whether the product can withstand a certain external pressure without damage during use, thereby affecting the user experience and personal safety. The existing technology still has the following problems: 1. When detecting the compression strength of household appliances, the household appliances need to be clamped and fixed. The existing compression strength detection device cannot uniformly clamp household appliances with irregular shapes. Moreover, the clamps themselves are prone to deformation and deviation during long-term use. If the clamping force is too large, the surface of the object may be deformed, scratched, or even structurally damaged. If the clamping force is too small, the object may slide or shift during the detection process, affecting the detection results. In addition, it is difficult to detect the sliding of the sample in the clamp in a timely manner, which causes the collected pressure data to deviate from the actual pressure acting on the sample, resulting in inaccurate detection results and failing to truly reflect the compression performance of the sample in the actual use scenario, thereby affecting the evaluation of product quality.

[0003] 2. The existing compression strength detection device can only buffer a single sample test piece, so that other models of products do not have a buffering effect when being inspected. When the pressure is suddenly applied, the sample will instantly bear the full force, causing cracks or damage to the surface of the sample. The lack of buffering will accelerate the damage process, making the detection impossible under the normal stress state of the sample, and unable to accurately obtain the real compression strength data of the sample. Long-term use of the equipment will cause the parts to wear and loosen, which will also damage the stable transmission of pressure, causing pressure deflection. Pressure deflection may cause uneven stress on the equipment, which will accelerate the wear of the equipment parts, reduce the precision and service life of the equipment, and increase the maintenance cost.

[0015] The technical scheme provided by the application has at least the following technical effects or advantages: 1. By employing a clamping assembly, this invention effectively solves the problems of existing compressive strength testing devices being unable to uniformly clamp irregularly shaped household appliances, and the clamps themselves being prone to deformation and displacement during prolonged use. Excessive clamping force may cause deformation, scratches, or even structural damage to the surface of the item; insufficient force may cause the item to slide or shift during testing, affecting the test results. Furthermore, slippage of the test sample within the clamp is difficult to detect in a timely manner, causing a deviation between the collected pressure data and the actual pressure applied to the sample, resulting in inaccurate test results that fail to accurately reflect the compressive strength performance of the sample in actual use scenarios, thus affecting the assessment of product quality. This invention, through its clamping assembly, can... It can perform multi-point uniform clamping on irregularly shaped home appliances. Multi-point uniform clamping distributes force to multiple contact points, avoiding damage caused by local overload, ensuring uniform stress on the entire sample, improving the stability of the home appliance under test during clamping, and preventing deformation of the clamp during long-term use. When large stresses are generated, the clamp can switch from a rigid connection to a flexible connection. In addition, it can issue an alarm when the home appliance under test slides, reminding staff to perform maintenance. It ensures that the collected pressure data matches the actual pressure acting on the sample, improving the accuracy of the test results, and can truly reflect the compressive performance of the sample in actual use scenarios, thereby accurately assessing product quality.

[0016] 2. By employing a buffer component, this invention effectively solves the problem that existing compressive strength testing devices can only buffer a single sample, resulting in a lack of buffering effect when inspecting other models. When pressure is suddenly applied, the sample will instantly bear the full force, causing cracks and damage to the sample surface. The lack of buffering accelerates the damage process, making it impossible to conduct testing under normal stress conditions and accurately obtain the sample's true compressive strength data. Long-term use also leads to wear and loosening of equipment parts, disrupting stable pressure transmission and causing pressure deflection. This pressure deflection can cause uneven stress on the equipment, accelerating wear of equipment parts, reducing equipment accuracy and lifespan, and increasing maintenance costs. This invention, through its buffer component, can buffer different specifications of household appliances, preventing the sample from instantly bearing the full force and causing surface cracks and damage. It allows the tested sample to obtain real-time data under normal stress conditions, thus accurately obtaining the sample's true compressive strength data. It prevents pressure deflection during testing, which causes uneven stress on the equipment, improving equipment accuracy and lifespan, and reducing maintenance costs. Attached Figure Description
