The invention relates to the technical field of shared tire air supply, in particular to a tire air supply terminal and a shared use method. The terminal comprises a gas storage and release assembly which can store gas and release gas, is movable and is used for supplementing gas and / or releasing gas for a tire; the air inflation assembly is used for automatically inflating the air storage and release assembly; according to the scheme, the problems that a user needs to purchase an inflator pump, the cost is high, and charging is forgotten are solved, simultaneous use of multiple users can be met, and the actual application requirements in gas stations, parking lots and other scenes are met; the scheme is convenient and fast to operate and has the advantage of low cost, the gas storage tank, the compressor and other devices with mature technologies are adopted, the early-stage arrangement and installation cost is low, the service life of the equipment is long, the comprehensive cost of the equipment in the whole life cycle is low, and the use cost of single-time rental gas supply is low.

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.

The utility model discloses an axle inflation structure and an axle. The axle inflation structure comprises a shaft head, a hub, an air outlet assembly and an air inlet assembly. A flange of the hub is provided with an air conveying channel, and the air conveying channel forms an air outlet and an annular air inlet in the outer end face and the inner end face of the flange respectively. The inner end of the air outlet assembly is matched with the air outlet and communicated with the air conveying channel, and the outer end of the air outlet assembly is communicated to an air tap of the tire. The air inlet assembly is matched with the air inlet and communicated with the air conveying channel, the air inlet assembly comprises a fixing support fixedly connected with the shaft head, the fixing support is provided with an air inlet channel communicated with the air inlet, the inner end of the air inlet channel is connected with an air inlet pipe used for being communicated with a whole vehicle air pressure system, and an installation gap is formed between the fixing support and the flange. And a sealing ring is arranged in the mounting gap. By means of the structural design, the tire can be inflated through a whole vehicle air pressure system, automatic inflation is achieved, inflation at a designated place is not needed, and therefore tire inflation is convenient and flexible.
