Description

Technical Field

[0001] The utility model relates to the field of medical cleaning and disinfection of medical devices, in particular to a cleaning door device with an adjustable sealing gap. Background Art

[0002] The existing sealed door structure of medical cleaning and disinfection equipment has the following common structures: the first one is that the motor belt is raised and lowered synchronously, the upper part of the door frame is tightened by a lifting motor or an electric cylinder, and the lower part of the door frame is connected to the rotating shaft fixing seat on the bottom frame by a rotating shaft. The door frame can rotate around the rotating shaft fixing seat. The upper and lower parts of this structure are both fixed structures and cannot be adjusted. It has high requirements for the processing and matching of each component. The second one, proposed by patent CN104453531B, is that the motor belt is raised and lowered synchronously, and the upper part is placed horizontally with an electric push rod. The two ends of the electric push rod adopt a connecting rod structure to adjust the gap between the left and right ends. The disadvantage of this patent is that the force of the electric push rod is relatively large, and it relies on adjusting the length of the connecting rods on the left and right sides. It is difficult and cumbersome to adjust the pressing distance and to achieve fine-tuning of the pressing force. In addition, the patent for the rotating shaft that cooperates with the lower part does not reflect the ability to move back and forth to adjust the lower side gap. The third method, proposed in patent CN219464295U, uses an electric push rod to raise and lower the door frame. The bottom of the door frame is connected to a pivot mount on the bottom frame via a rotating shaft, which can be adjusted forward and backward. The upper end of the door frame is tightened by the push rod, and the push rod side is a fixed structure. This structure is adjustable at the bottom, but not at the top or left and right. Furthermore, the push rod tension force is too high, and an external microswitch is used to control the push rod's closed position. The locking force is too high, which can easily damage the rubber strip. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] A cleaning door device with adjustable sealing gap includes a cleaning door 1 and a door frame 2. The lower end of the door frame 2 is provided with a door frame shaft 17, the door frame shaft 17 is fixed on the shaft seat 19, the upper end 8 of the door frame is connected to the cylinder 3, the cylinder 3 is connected to the floating joint 10, the front end of the floating joint 10 is provided with an adjustment gasket 9, the adjustment gasket 9 is connected to the upper end 8 of the door frame, the cylinder 3 is fixed on the cylinder mounting plate 11, the shaft seat 19 and the cylinder mounting plate 11 are rigidly connected to the cabin, and pulleys or guides are installed on the two outer sides of the cleaning door 1 Block, a lifting motor 5 is provided at one end of the door frame 2, the lifting motor 5 is connected to the lifting synchronous belt 6, the lifting synchronous belt 6 is provided on the door frame 2, and a shaft adjustment plate 15 is provided at the lower end of the lifting synchronous belt 6. Threaded adjustment blocks 16 are provided at both ends of the shaft adjustment plate 15, and the adjusting thread block 16 is connected to the adjusting screw 20. The shaft adjustment plate 15 is provided on the supporting platform 7, the shaft adjustment plate 15 is connected to the shaft seat 19, the shaft seat 19 is connected to the door frame shaft 17, and a stopper 21 is provided at the lower end of the shaft adjustment plate 15.

[0019] The shaft seat 19 is fixed to the shaft adjustment plate 15 with screws. A long hole is provided on the shaft adjustment plate 15. A threaded hole is provided at the eccentric end of the door frame shaft 17. The bolts fix the stopper 21 and the door frame shaft 17 together. There are long holes on both sides of the stopper 21, and the stopper 21 and the shaft adjustment plate 15 are fixed together with screws.

[0020] The lower end of the door frame can rotate around the door frame shaft, and the door frame shaft is fixed to the shaft seat. The upper end of the door frame is connected to the cylinder, and the cylinder is fixed to the cylinder mounting plate. The shaft seat and the cylinder mounting plate are all rigidly connected to the cabin. Pulleys or guide blocks are installed on the two outer sides of the cleaning door. The cleaning door can move up and down along the inner side of the door frame through the pulleys or guide blocks under the action of the lifting device. When the upper end of the door frame is driven and tightened by the cylinder, it rotates around the rotating shaft at the lower end, driving the cleaning door to move together, so that the cleaning door presses against the rubber strip. When the upper end of the door frame is loosened by the cylinder, it rotates around the rotating shaft at the lower end, driving the cleaning door to move together, so that the cleaning door is away from the rubber strip.

[0021] Threaded adjustment blocks are welded to the front and back sides of the pivot adjustment plate. The pivot seat and pivot adjustment plate are secured together with screws. The pivot adjustment plate has an elongated hole, allowing the pivot seat to be adjusted forward and backward on the pivot adjustment seat. Once positioned, the screws on the threaded adjustment block can be used to reinforce the fixation. The door frame pivot passes through the lower end of the door frame and the pivot seat, allowing the door frame to rotate around the pivot. A threaded hole is located eccentrically at the end of the door frame pivot, and bolts are used to secure the retaining plate and door frame pivot together. The retaining plate has elongated holes on both sides, and screws are used to secure the retaining plate and pivot adjustment seat together. The retaining plate, guide rail pivot, and pivot seat as a whole can be adjusted forward and backward on the pivot adjustment seat, thereby adjusting the distance between the lower ends of the door frame and the cabin rubber strip, and thus adjusting the depth of the press fit between the lower ends of the cleaning door and the rubber strip.

[0022] A pressure-regulating valve is installed at the cylinder's air intake to adjust the intake pressure, and thus the cylinder's tension. A floating joint connects the cylinder to the door frame, allowing for a certain amount of movement in all directions. Wedge-shaped guide blocks are installed between the door frame and the cylinder's mounting plate. This ensures a gap between the guide blocks when tightening, allowing the compressed wash door to self-adjust under the reaction force of the rubber strip. When loosened, the guide blocks close, ensuring a clear distance between the wash door and the rubber strip, preventing interference with the rubber strip when the wash door opens.

[0023] A cleaning door device with an adjustable sealing gap according to the claim is characterized in that there is a certain gap between the floating joint and the door frame, and an adjusting gasket can be inserted to adjust the size of the gap, thereby fine-tuning the pressing depth between the upper side of the cleaning door and the rubber strip.
