2results about How to "Realize automatic inflation" patented technology

The utility model discloses a kind of automatic inflating balls, including hollow sphere, hollow sphere is the elastic sphere of being able to elastically deform, recessed with inflation hole on the ball wall of hollow sphere, inflation hole is through the inside and outside of hollow sphere along the wall thickness direction of hollow sphere;When automatic inflation, under the extrusion of hollow sphere, extrusion of external force is removed, hollow sphere can elastically deform and restore to original sphere shape under the action of its own elastic force, during the recovery of hollow sphere, external gas enters hollow sphere through inflation hole;The average diameter of hollow sphere is ball diameter D;The average wall thickness T of hollow sphere satisfies the following function: T=T 127 × (D / 127) M , the aperture H of inflation hole of hollow sphere satisfies the following function: H=H 127 × (D / 127) 0.5 ;By this, it realizes the automatic inflation of ball, without inflator, experience is strong, and can quickly recover, and good resilience.

This utility model provides an automatic testing bench for the calorific value of building materials, belonging to the technical field of calorific value testing equipment. It includes a support frame, a rotating mechanism, an insulated container, an extraction mechanism, and a filling mechanism. Through the coordinated operation of the rotating mechanism, extraction mechanism, and filling mechanism, automatic filling, handling, and testing of oxygen bombs are achieved. The operator only needs to place multiple oxygen bombs and add building material powder at once; the system can then complete the filling, transfer, and testing processes sequentially according to a preset program, eliminating the need for manual operation. This design not only significantly improves testing efficiency but also frees the operator's hands, allowing them to perform other tasks simultaneously. Furthermore, the automated process reduces human error and improves the accuracy and consistency of test data. The automated design of the filling mechanism avoids the potential dangers of manual operation of high-pressure oxygen, reduces safety risks during the testing process, and ensures the personal safety of the testing personnel.
