[0002] Refer to Figure 1 As shown, during the actual assembly of the air valve, the valve core 110 needs to be assembled into the valve body 100. Since the valve core 110 and the valve body 100 are generally connected by threads, the valve core 110 needs to be screwed into the valve body 100. However, since there is no force application point provided at the top of the cylindrical valve core 110, it is very difficult for manual labor to directly screw the valve core 110 completely into the valve body 100 from the outside. Moreover, the processing efficiency of manual screwing is low, and the assembly quality cannot be effectively guaranteed. Therefore, improvement is needed. Summary of the Utility Model

A downwardly arranged pressing drive cylinder is installed at the center of the top plate. A connecting bracket is installed on the telescopic shaft of the pressing drive cylinder, and the connecting bracket is connected to the moving seat. A sleeve penetrating the moving seat downward is arranged at the center of the moving seat. A pressing and limiting seat is installed at the bottom of the sleeve. A screwing shaft is installed vertically in the sleeve and extends to the bottom of the pressing and limiting seat. A pressing head protrusion is installed at the bottom of the screwing shaft. A screwing sleeve handle is sleeved on the screwing shaft. A valve body limiting and supporting seat is installed on the bottom plate below the pressing head protrusion.

[0005] In the above technical solution, during actual operation, only need to embed the valve body onto the valve body limit support seat of this equipment and fix it, then place the valve core into the valve body. First, manually screw in a small section, and then turn on the downward pressing drive cylinder. The downward pressing drive cylinder drives the moving seat to press down, so that the pressing head protrusion is embedded in the valve core. Then, drive the screwing shaft to rotate by repeatedly turning the sleeve handle (when turning the sleeve handle forward, it can drive the screwing shaft to rotate together, but when turning the sleeve handle backward, the screwing shaft does not rotate). Drive the pressing head protrusion to rotate through the screwing shaft, and drive the valve core to rotate. Then, under the cooperation of the downward pressing drive cylinder and the pressing limit seat, continuously screw the valve core into the valve body until the valve core is screwed in place. Then, the downward pressing drive cylinder drives the moving seat to reset, and withdraw the assembled component from the pressing head protrusion. The operation is very convenient, and effectively improves the assembly efficiency and assembly quality between the valve core and the valve body.

[0006] Preferably, a shaft head is installed at the top of the screwing shaft, and the shaft head is detachable, which is convenient for the installation and replacement of the sleeve handle.

It can well screw the valve core into the valve body, with high assembly efficiency and good assembly quality. During actual work, only need to embed the valve body on the valve body limit support seat of this equipment and fix it, then put the valve core into the valve body. First, manually screw it in a short section, and then turn on the downward pressing drive cylinder. The downward pressing drive cylinder drives the moving seat to press down, so that the pressing head protrusion is embedded in the valve core. Then, repeatedly drive the screwing shaft to rotate by turning the sleeve handle (when turning the sleeve handle forward, it can drive the screwing shaft to rotate together, but when turning the sleeve handle backward, the screwing shaft does not rotate). Drive the pressing head protrusion to rotate through the screwing shaft, and drive the valve core to rotate. Then, under the cooperation of the downward pressing drive cylinder and the pressing limit seat, continuously screw the valve core into the valve body until the valve core is screwed in place. Then, the downward pressing drive cylinder drives the moving seat to reset, and withdraw the assembled component from the pressing head protrusion. The operation is very convenient, and effectively improves the assembly efficiency and assembly quality between the valve core and the valve body. Description of the Drawings
