Detailed Description

The present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1, the protective airtight door with the self-locking device in the present embodiment includes a door leaf 1 and a door panel 2 installed on the door leaf 1; the door is characterized by also comprising a limiting lock rod 3 which is rotatably arranged on the door leaf 1 and a limiting sliding plate 4 which is slidably arranged on the door leaf 1 and limits the limiting lock rod 3; through the arrangement of the limiting lock rod 3, the door plate 2 is limited and locked by the rotation of the limiting lock rod 3 along the rotating shaft 5, so that the door plate 5 is convenient to self-lock, the door locking efficiency is improved, and the labor intensity of workers is reduced; through the setting of spacing slide 4, utilize spacing slide 4 to carry on spacingly to spacing locking lever 3 to be convenient for spacing to spacing locking lever 3.

Referring to fig. 1-5, a rotating shaft 5 is installed on the limit lock rod 3 by welding; the door leaf 1 is provided with a rotating groove 101 matched with the rotating shaft 5; the door plate 2 is provided with a locking groove 201 matched with the limit locking rod 3; the limiting lock rod 3 is also provided with a limiting boss 301 matched with the limiting sliding plate 4; a limiting plate 501 is mounted on the rotating shaft 5 through a screw; the rotating shaft 5 is limited and installed on the door leaf 1 through a limiting plate 501; the door leaf 1 is provided with a sliding groove 102 matched with the limiting sliding plate 4; a guide boss 103 is arranged in the sliding groove 102; the limiting sliding plate 4 is provided with a guide groove 401 matched with the guide boss 103 and a limiting groove 402 matched with the limiting boss 301; a pull rod 403 is further installed on the limiting sliding plate 4 through welding; the guide groove 401 on the limit sliding plate 4 is matched with the guide boss 103 in the sliding groove 102 to slide along the guide boss 403, so that the function of guiding the sliding of the limit sliding plate 4 is achieved; the limiting lock rod 3 is limited through the matching of the limiting groove 402 on the limiting sliding plate 4 and the limiting boss 301 on the limiting lock rod 3, so that the limiting lock rod 3 is limited conveniently; the pull rod 403 on the limit sliding plate 4 pulls the limit sliding plate 4 to move along the guide boss 103, so that the limit sliding plate 4 is convenient to move.

Referring to fig. 1, a plurality of mounting seats 104 are further installed on the door leaf 1 by welding; the door panel 2 is provided with a rotating block 202 matched with the mounting seat 104; a rotating pin 203 is connected and installed between the installation seat 104 and the rotating block 202.

In the utility model, when the protective airtight door needs to be closed, the door plate 2 is pushed to rotate along the rotating pin 203 to be closed with the door leaf 1, the door plate 2 pushes the limiting sliding plate 4 to move along the guide boss 103 into the sliding groove 102 before closing to lose limiting force on the limiting locking rod 3, and simultaneously, after the limiting locking rod 3 loses the limiting force, the limiting locking rod 3 falls into the locking groove 201 on the door plate 2 because the weight of the limiting locking rod 3 rotates along the rotating shaft 5, so that the door plate 2 is locked and limited; when the protective airtight door needs to be opened, firstly the limiting lock rod 3 is pulled to rotate in the opposite direction along the rotating shaft 5, meanwhile, the limiting sliding plate 4 is pulled to move outwards along the guide boss 103 through the pull rod 403, so that the limiting groove 402 on the limiting sliding plate 4 is matched with the limiting boss 301 on the limiting lock rod 3, the limiting lock rod 3 is limited, and then the door plate 2 is pulled to rotate along the rotating pin 203 to open the door.

The above embodiments are illustrative of the present invention, and are not intended to limit the present invention, and any simple modifications of the present invention are within the scope of the present invention.
