Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings.

In fig. 1 and 2, the device comprises a lifting plate 1, a cylinder floating joint 2, a cylinder 3, a guide rod 4, a linear bearing 5, a sealant 6, an upper cover plate 7, a guide rod floating joint 8, a lifting support frame 9, a guide wheel guide side plate 10, a guide wheel 11, a guide wheel limit plate 12, a sealing door 13, a movable diagonal draw bar 14, a door edge sealing rubber strip 15 and the like.

As shown in fig. 1 and 2, the utility model relates to an automatically-controlled door with seal structure, include and install the upper cover plate 7 on the fixing base die cavity when using, the installation can make progress jacking cylinder 3 in the middle of the upper surface of upper cover plate 7, lifter plate 1 is connected to the tailpiece of the piston rod of cylinder 3, lifter plate 1's bottom surface sets up guide bar 4 respectively along length direction both ends, guide bar 4 passes upper cover plate 7 downwardly extending and sets up, lift supports 9 is connected to the lower extreme of guide bar 4, sealing door 13 is connected with lift supports 9 through activity diagonal draw bar 14, sealing door 13 sets up two rows of guide pulleys 11 of arranging along vertical direction respectively along length direction both ends, set up guide pulley direction curb plate 10 between two rows of guide pulleys 11. The two ends of the movable diagonal draw bar 14 along the length direction are respectively provided with a round hole, and the two round holes are respectively hinged with the connecting parts of the lifting support frame 9 and the sealing door 13.
