Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
As shown in fig. 1 and fig. 2, an automatic latch bolt structure comprises an automatic latch bolt 1, an automatic latch bolt seat 2, a control block 3 and a shell 4. The automatic latch bolt 1 is provided with: the door locking device comprises a door locking vertical flange 11, a door collision inclined flange 12, a supporting round hole 13, a limiting flange 14 and a control flange 15. The automatic oblique tongue seat 2 is provided with: the lower limiting rib 22 and the upper limiting rib 23 of the supporting round shaft 21 lock the guide groove 24. On the control block 3 are: a stop pin 31. Through the matching of the supporting round hole 13 and the supporting round shaft 21, the automatic oblique tongue 1 is sleeved on the automatic oblique tongue seat 2, and the automatic oblique tongue 1 can rotate relative to the automatic oblique tongue seat 2; the control block 3 is arranged in a locking guide groove 24 of the automatic oblique tongue seat 2, and the control block 3 can move left and right in the locking guide groove 24.
As shown in fig. 3, when the door-collision inclined flange 12 on the automatic latch bolt 1 is pushed by door-collision thrust generated by closing the door or the like, the automatic latch bolt 1 cannot rotate clockwise relative to the automatic latch bolt base 2 because the limit flange 14 abuts against the lower limit flange 22, and the door-collision thrust pushes the automatic latch bolt 1, the automatic latch bolt base 2 and the control block 3 to move rightwards integrally due to the inclined surface of the door-collision inclined flange 12, and the door is retracted into the housing 4, so that the automatic door closing is realized.
As shown in fig. 3, when the control block 3 moves to the left end of the locking guide groove 24, the control rib 15 abuts against the stop pin 31, and when the vertical door locking rib 11 on the automatic latch bolt 1 is pushed by an external force in the door locking thrust direction, the automatic latch bolt 1 cannot rotate counterclockwise relative to the automatic latch bolt seat 2 because the control rib 15 abuts against the stop pin 31; meanwhile, the door locking vertical flange 11 is vertical to the door locking thrust direction, and the door locking thrust cannot push the automatic oblique bolt 1, the automatic oblique bolt seat 2 and the control block 3 to integrally move rightwards and cannot retreat into the shell 4, so that the automatic door locking is realized.
As shown in fig. 4 and 5, when the control block 3 moves to the right of the locking guide groove 24, the control rib 15 and the stop pin 31 do not abut against each other, and when the vertical rib of the door 1 on the automatic latch bolt 1 is pushed by an external force in the direction of the pushing force of the door, as shown in the figure, the control rib 15 and the stop pin 31 do not abut against each other, the automatic latch bolt 1 will rotate counterclockwise relative to the automatic latch bolt seat 2 until the position where the control rib 15 abuts against the upper limit rib 23 is shown in the figure; at the moment, a large oblique angle is formed between the door locking vertical retaining edge 11 and the door locking thrust direction, namely the door locking vertical retaining edge 11 rotates into an oblique retaining edge, the door locking thrust pushes the automatic oblique bolt 1, the automatic oblique bolt seat 2 and the control block 3 to integrally move rightwards under the action of the oblique angle, and the automatic door is returned to the shell 4, so that the automatic door opening is realized.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modification, equivalent replacement or improvement made within the spirit and principle of the present invention should be included in the present invention.
