The clamp ring 13 is a large nut with single-ended serrated section engagement threads and serrated closure heads. The handle is used for rotating the gear shaft 14 to drive the compression ring 13 to rotate, so that the rear end face of the shell and the rear cover can be compressed or loosened, and when the serrated end socket of the compression ring 13 is compressed on the corresponding tooth of the rear cover, the rear cover is compressed on the rear end face of the cylinder, otherwise, the rear cover is loosened. The stopper 10 in the front and rear cover interlocking mechanism is protruded into the bottom slot of the interlocking sector plate 12 for limiting the rotation angle of the clamp ring 13.
In the above embodiment, the sealing ring is installed in the front cover to ensure the sealing of the front cover to the cylinder after the front cover is closed, and the sealing ring is fixed on the front cover by the extrusion ring.
In the above embodiment, the sealing cup is installed in the rear cover, and the rear cover is pressed on the cylinder body by rotating the pressing ring to form a seal for the cylinder body.
In the above embodiment, a limit switch may be installed on the first bracket or the second bracket to perform indication of the front cover opening/closing signal.
What is not described in detail in this specification is prior art known to those skilled in the art.
In summary, the above embodiments are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention. The invention realizes the opening and closing functions of the front cover and the rear cover of the cylinder body, and can realize the interlocking function of opening the front cover and the rear cover through the interlocking mechanism of the front cover and the rear cover, thereby ensuring the safety of equipment and preventing misoperation.
