Detailed Description
The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings, in which preferred embodiments in the description are given by way of example only, and all other embodiments obtained by those skilled in the art without making any inventive effort are within the scope of protection of the present utility model.
As shown in fig. 1 to 10, the present embodiment adopts the following technical scheme: it comprises a mounting base plate 1, a door pushing plate 6 and a locking pin 7; the lock pin 7 is fixed on the door pushing pin plate 6, and the lock pin 7 is arranged towards one side of a worker, and the left door pushing pin plate 6 and the right door pushing pin plate 6 are respectively fixed on the left sliding door 8 and the right sliding door 8; two travel switches 13 are arranged on the mounting bottom plate 1, and the travel switches 13 are externally connected with an electric control end by utilizing a wire harness 14; the mounting bottom plate 1 is symmetrically provided with a V-shaped large notch 1-1 in a left-right mode; the back surface (the side far away from the staff) of the mounting bottom plate 1 is connected with a manual unlocking plate 10, and the manual unlocking plate 10 is movably connected with an unlocking pin shaft 9; it also comprises:
the two lock hooks 2 are respectively connected to the mounting bottom plate 1 in a bilateral symmetry rotation way by utilizing a shaft I11, and the lock hooks 2 are movably hooked with the lock pins 7;
The two limiting plates 3 are respectively connected to the mounting bottom plate 1 in a bilateral symmetry rotation mode through a shaft II 12, the limiting plates 3 are movably contacted with the lock pins 7, a bow-back-shaped structure 3-1 is arranged on the limiting plates 3, and a gap between the limiting plates 3 and the lock pins 7 is 3mm;
The automatic unlocking plate 5 is movably inserted with an unlocking pin shaft 9 in a strip-shaped groove formed in the automatic unlocking plate 5, and the unlocking pin shaft 9 is connected to the back surface of the locking hook 2;
The electromagnet 4 is fixed on the mounting bottom plate 1 and positioned between the two travel switches 13, and the sliding rod end of the electromagnet 4 is connected with the automatic unlocking plate 5; the electromagnet 4 is externally connected with an electric control end by using a wire harness 14.
Before the utility model is used, the mounting bottom plate is mounted on a door machine beam by using a bracket, when the door machine beam is used, the electromagnet 4 is electrified, the sliding rod of the electromagnet 4 moves upwards, so that the automatic unlocking plate 5 is driven to move upwards, the unlocking pin shaft 9 is driven to move upwards while the automatic unlocking plate 5 moves upwards, the locking hook 2 is driven to rotate around the first shaft 11 for a certain angle to open and separate from the locking pin 7, meanwhile, the limiting plate 3 rotates in the opposite direction of the rotation of the locking hook 2, when the limiting plate 3 rotates below the unlocking pin shaft 9, the rotation is stopped, the unlocking pin shaft 9 is supported, the unlocking state is kept (as shown by the state of the left limiting plate 3 and the locking hook 2 in the figure), and the electromagnet 4 is powered off and loses magnetism; when the sliding door 8 is closed, the door pushing pin plate 6 is driven to move towards the V-shaped large notch 1-1 until the lock pin 7 enters the V-shaped large notch 1-1, the lock pin 7 triggers the bow-back structure 3-1 of the limiting plate 3, so that the limiting plate 3 is pushed to rotate, at the moment, the unlocking pin shaft 9 loses support and limitation, the automatic unlocking plate 5 falls under the action of gravity, meanwhile, the lock hook 2 rotates in the opposite direction of the rotation of the limiting plate 3 under the driving of the unlocking pin shaft 9, the lock pin 7 is locked by the lock hook 2, and the sliding door cannot be opened in the door opening direction.
