Description

Technical Field

[0001] The utility model relates to the field of air mattress testing equipment, in particular to a point pressure device for testing an air mattress. Background Art

[0002] An air mattress is a portable mattress that can provide sleeping support and comfort by being inflated. They are usually made of soft materials such as PVC (polyvinyl chloride) or nylon, and are inflated with air to provide support. The portability of an air mattress is one of its major advantages. They can usually be inflated by a manual or electric pump, and the inflation pressure can be adjusted according to personal preferences and needs to obtain the desired hardness and comfort level. Compared with traditional mattresses, inflatable mattresses are lighter, easier to fold and carry, and are very suitable for camping, traveling and outdoor activities. In order to ensure the durability and structural stability of the inflatable mattress, some inflatable mattresses have undergone point pressure tests. These tests can evaluate the performance and stability of the mattress when it is subjected to pressure and movement (such as rolling and changes in sleeping posture) during daily use. The purpose of the point pressure test is to ensure that the inflatable mattress can provide lasting sleep support without damage or deformation.

[0003] However, existing point pressure equipment for testing air mattresses often cannot ensure that the air mattress maintains a stable position and range during the test. Since the air mattress is soft and highly mobile, the test equipment often cannot provide sufficient support or fixings to prevent the mattress from shifting or deforming during the test, which may lead to inaccurate and unreliable test results. Existing equipment also has the challenge of adapting to air mattresses of different sizes. Air mattresses come in various sizes and shapes, and the test equipment is often only suitable for mattresses of specific sizes or types. Additional manpower or auxiliary devices may be required to maintain the stability of the mattress, which increases the complexity and inconvenience of the test. Utility Model Content
