The application discloses a fire spraying gun nozzle, which comprises a connecting end and a nozzle end connected with each other, the connecting end is provided with an air inlet channel, the nozzle end is internally provided with an air inlet cavity, an air outlet hole, an air outlet cavity, a gas storage cavity, a first connecting channel and a second connecting channel, one end of the air inlet cavity is communicated with the air inlet channel, the other end of the air inlet cavity is communicated with one end of the air outlet hole, the other end of the air outlet hole is communicated with the air outlet cavity, the gas storage cavity is communicated with the air inlet cavity through the first connecting channel, and the gas storage cavity is communicated with the air outlet cavity through the second connecting channel. When the fire spraying gun nozzle is used for spraying fire, combustible mixed gas is sprayed out after entering the nozzle end from the connecting end, and at the same time, the combustible mixed gas enters the gas storage cavity through the first connecting channel and is radially output to the air outlet cavity through the second connecting channel. The gas pressure radially output can slow down the speed of the mixed gas sprayed out from the air outlet hole, avoids the flame from being too far away from the nozzle end to be extinguished, and plays a role in stabilizing the flame.

The invention discloses an ejection structure for a mobile phone support product, and relates to the technical field of mobile phone support product ejection, the ejection structure comprises a mold base and a first assembly mounted on the mold base, the cross section of the mold base is U-shaped, and the first assembly comprises an ejection transmission assembly, a mold forming assembly and a guide positioning assembly; the ejection transmission assembly comprises an ejector pin bottom plate and an ejector pin panel, the ejector pin bottom plate is in transmission connection with the ejector pin panel through a guide column, and the ejector pin panel is provided with a positioning hole used for installing the ejection execution assembly; through cooperative operation of a sliding rod, a spiral groove, a limiting body and the like in the fourth assembly, linear ejection force restored by a spring is converted into stable rotary lifting motion, the ejection speed of the inclined ejection block is further reduced through the design of a large spiral lead, the lifting stability is improved, uniform power transmission is achieved in cooperation with composite ejection motion of the inclined ejection block in the 45-degree direction, and the service life of the inclined ejection block is prolonged. And the problem of unbalanced ejection of the small bracket is thoroughly solved, and the product deformation rate is reduced to an extremely low level.

The utility model discloses a truss beam formula hanging basket suspending pouring structure relates to the technical field of suspending pouring construction, including the pouring bridge and hoisting base, the top fixed connection of pouring bridge has the symmetrical laying track, and the top of two laying tracks all is provided with the sliding frame, and the top of two sliding frames all is fixedly connected with the main frame beam, and the front end fixed connection of two main frame beams has the front hanger, and the rear hanger is all provided with on two sliding frames. The utility model discloses a truss beam formula hanging basket suspending pouring structure can avoid the phenomenon of segregation that the impact force is too big when the concrete is discharged because of too high height when pouring, can change the ejection direction of concrete when pouring through the arc elbow, and the arc elbow can reduce the ejection speed of concrete, avoids the phenomenon of concrete segregation that concrete directly impacts the formwork or the steel reinforcement framework, is favorable for promoting the compactness of concrete.
