Specifically, after the upper end enclosure is locked, the foot-operated switch mechanical linkage device (foot-operated linkage device) can be locked or unlocked in the controller according to the use state of a user, and the user can be ensured not to open the upper end enclosure when a product runs.

The invention relates to a quick-opening type sealing scheme with mechanical and electrical design, which comprises a locking mode, a pedal mechanical linkage mode, an electrical control logic, an electrical control pedal linkage locking mode and a cantilever design mode. The adopted electric control logic is as follows: 1. the controller detects the pressure value in the cylinder; 2. the controller marks the running state of the equipment: when the controller detects that the pressure in the cylinder body and the atmospheric pressure are in a balanced state through the pressure sensor, whether the equipment is in an operating state is judged, if the equipment is in the operating state, the electromagnetic coil is kept in a power-off locking state, and when the equipment is in a shutdown state and the pressure inside and outside the cylinder body is in the balanced state, the electromagnetic coil is electrified, so that the electromagnetic bolt is retracted, and a pedal type door opening mechanism (namely a pedal linkage device) is unlocked.

Example 2

As shown in fig. 4 to 7, a pressure vessel quick-opening structure includes: the device comprises a cylinder body 11, an upper seal head 12, a lower seal head 9 and a rotating device, wherein the upper seal head 12 and the lower seal head 9 are respectively arranged at the top end and the bottom end of the cylinder body 11 to form a container with a closed cavity inside; one side of the rotating device is fixed on the cylinder body 11, and the other side of the rotating device is connected with the upper sealing head 12 and used for realizing the opening and closing of the upper sealing head 12; a sealing ring is arranged on the inner wall of the upper end enclosure 12, and after the upper end enclosure 12 is closed and is closed with the cylinder body 11, the sealing ring is deformed under the combined action of the upper end enclosure 12 and the cylinder body 11, so that the upper end enclosure 12 and the cylinder body 11 are sealed and locked; a locking device is commonly connected between the upper end enclosure 12 and the cylinder body 11, and when the upper end enclosure 12 is pushed upwards under the action of pressure in the cylinder body 11, the upper end enclosure 12 and the cylinder body 11 are fastened by the locking device; the pressure sensor for detecting pressure is arranged in the cylinder body 11, the locking device is electrically connected with the controller, the pressure sensor is electrically connected with the controller, when the pressure sensor detects that the cylinder body 11 is in an openable state, a signal is sent to the controller to control the locking device to unlock, so that the upper sealing head 12 and the cylinder body 11 are in a separable state, and meanwhile, the upper sealing head 12 is opened by utilizing the rotating device.

In the embodiment, the locking device is composed of a seal head tooth sleeve ring 16 and a cylinder body tooth sleeve ring 17, the seal head tooth sleeve ring 16 is connected with the upper seal head 12 through a slide rail, and the seal head tooth sleeve ring 16 rotates around the central shaft of the upper seal head 12 along the slide rail; a handle 18 is arranged on the head tooth lantern ring 16, a plug pin hole 21 is formed in one side of the handle 18, an electric plug pin used for locking the head tooth lantern ring 16 is connected into the plug pin hole 21, the electric plug pin is connected with an electromagnetic solenoid coil, and the electromagnetic solenoid coil is electrically connected with a controller; the cylinder gear lantern ring 17 is fixedly connected with the top of the cylinder 11; a plurality of teeth I19 are arranged in the circumferential direction of the head tooth lantern ring 16, and a plurality of teeth II 20 which are matched and connected with the teeth I are arranged in the circumferential direction of the barrel tooth lantern ring 17; the teeth I19 and the teeth II 20 are provided with gaps, and when the upper seal head 12 is pushed upwards under the action of pressure in the cylinder 11, the teeth I19 and the teeth II 20 are in contact connection and used for fastening the upper seal head 12 and the cylinder 11 to prevent the upper seal head 12 from being pushed; when the pressure sensor detects that the barrel body 11 is in an openable state, the controller controls the electromagnetic solenoid to be powered on, the electric plug is recycled, the seal head gear sleeve ring 16 is unlocked and can rotate, the handle 18 is manually rotated to drive the seal head gear sleeve ring 16, the teeth I19 and the teeth II 20 are staggered, the tight connection between the seal head gear sleeve ring 16 and the barrel body gear sleeve ring 17 is released, the upper seal head 12 can be opened upwards by utilizing the rotating device at the moment, and the quick-opening design is realized. The surface where teeth I19 and II 20 contact has a small slope, which is to facilitate the feel of the turn, giving a significant feedback confirming that the closure tooth collar 16 is sliding in place.

In this embodiment, the rotating device is composed of a cantilever 1 and a cantilever support 15, one side of the cantilever 1 is fixedly connected with the top end of an upper end enclosure 12 through a cantilever fixing nut 14, the end part of the other side is rotatably connected with the cantilever support 15 through a cantilever fixing shaft 13, the cantilever support 15 is fixed on the outer wall of a cylinder 11, and the opening and closing of the upper end enclosure 12 are realized through the rotation of the cantilever 1 around the cantilever support 15 (the upper end enclosure 12 can be automatically opened, the upper end enclosure 12 can also be manually opened, and when the upper end enclosure 12 is automatically opened, the cantilever 1 can be controlled by a motor to drive the upper end enclosure 12 to rotate and open).
