Referring to fig. 1 to 3, the present invention provides an automatic latch mechanism, which is installed on the passive leaf of various vertical hinged doors. This automatic bolt mechanism includes: the mounting seat 1, the bolt component 2 and the elastic movement component 3; the elastic movement assembly 3 comprises: a latch tongue 31, a rotating piece 32, a guide rod 33, a return spring 34 and a spring stop piece 35.

The upper portion of the mounting seat 1 is provided with a first through hole, the guide rod 33 comprises a first rod portion 331 and a second rod portion 332 which form a certain angle with each other, the first rod portion 331 is connected with the plug pin component 2, the middle upper portion of the first rod portion 331 is embedded into the first through hole, so that the first rod portion 331 can slide up and down in the first through hole, and the second rod portion abuts against the other end of the rotating sheet 32. The end, far away from the guide rod 33, of the first through hole is provided with the spring blocking piece 35, the spring blocking piece 35 is provided with a third through hole, and the bolt component 2 penetrates through the third through hole. Specifically, the return spring 34 is sleeved on the latch assembly 2 and is disposed in the first through hole, one end of the return spring 34 abuts against the spring blocking piece 35, and the other end of the return spring abuts against the end of the first rod portion 331. The first rod part 331 and the second rod part 332 mutually form an angle of 90-180 degrees. The contact position of the second rod part 332 and the rotating sheet 32 is a plane, so that the relative movement is continuous and smooth, and the phenomenon of clamping cannot occur.

The rotating piece 32 is rotatably mounted on the mounting base 1, and specifically, may be mounted on the mounting plate 13 at the lower portion of the mounting base 1. In this embodiment, the rotating plate 32 is in a "T" shape, and is provided with an installation position, the installation position is hinged to the installation plate 13 of the installation seat through a rotating pin, one end of the rotating plate 32 abuts against the latch tongue 31, the other end of the rotating plate abuts against the second rod 332, the length from the end part of the other end of the rotating plate 32 to the installation position is greater than the length from the end part of one end of the rotating plate 32 to the installation position, and in this structure, the torque generated when the return spring 34 pushes the rotating plate 32 to rotate is greater, so that the latch tongue 31 is pushed to reset. Both ends of the rotating sheet 32 are spherical structures, so that the transition is smooth when the rotating sheet 32 rotates, and the rotating sheet 32 is favorable to rotate so as to avoid clamping the rotating sheet 32.

A second through hole (not marked) is formed in the lower portion of the mounting base 1; the latch tongue 31 is slidably mounted on the second through hole, and one end of the latch tongue protrudes outwards after passing through the second through hole, so that the latch tongue 31 can collide with the driving fan to generate extrusion. Specifically, the method comprises the following steps: the mounting plate of the mounting base 1 is provided with a containing cavity 12 for containing the latch bolt 31, the containing cavity 12 is communicated with the second through hole, and the latch bolt 31 plays a role in guiding and stabilizing the latch bolt 31 when sliding on the second through hole. The latch tongue 31 comprises a tongue piece 311 and a push rod 312, the tongue piece 311 is arranged at one end of the latch tongue 31, which is abutted against the rotating sheet 32, and is abutted against one end of the rotating sheet 32, and the contact position of the latch tongue 31 and the rotating sheet 32 is a plane, so that the relative movement is continuous and smooth, and the phenomenon of clamping cannot occur. The width of the tongue piece 311 is larger than the aperture of the second through hole, so that the latch tongue 31 cannot be pulled out from the accommodating cavity 12. The top end of the push rod 312 far from the tongue piece 311 is provided with at least one inclined surface, so that the pushing action of the main fan is more easily received to enable the latch tongue 31 to slide in the accommodating cavity 12.

Bolt subassembly 2 include screw rod 21 and with bolt 22 that screw rod one end is connected, screw rod 21 one end with bolt 22 threaded connection, the screw rod 21 other end adopt the screw thread mode with first pole portion 331 is connected. The length of the latch assembly 2 can be adjusted according to the length of the screw 21 screwed into the latch 22 and the first rod 331 by adopting a threaded connection mode, so that the automatic latch structure can be suitable for door leaves of various sizes. As shown in fig. 2, the automatic latch mechanism is installed at the upper and lower positions of the passive leaf of the double-leaf vertical hinged door, when the active leaf is closed, the active leaf door collides with the latch tongue 31 and presses the top end inclined surface of the push rod 311, the latch tongue 31 moves leftwards, the tongue piece 311 presses one end of the rotating piece 32 leftwards, due to the hinged connection between the installation position of the rotating piece 32 and the installation seat, the pushing force of the tongue piece 311 is converted into clockwise rotation of the rotating piece 32, at this time, the other end of the rotating piece 32 pushes the second rod part 332 of the guide rod upwards, further the first rod part 331 is pushed upwards, the return spring 35 is compressed, at this time, the latch assembly 2 rises upwards along with the first rod part 331, and the latch assembly 2 is inserted into a jack arranged in a door frame or other peripheral devices, so as to lock the latch mechanism.

Similarly, when the active fan pushes away, the elastic action of the return spring 35 pushes the first rod part 331 of the guide rod 33 to move downward and simultaneously pushes the second rod part 332 to move downward, the second rod part 332 exerts a force on the rotating piece 332, the rotating piece 32 rotates counterclockwise, the latch tongue 31 is pushed to move rightward, and the latch tongue 31 returns to the original position. It should be mentioned that an opening is disposed on the upper side of the accommodating cavity 12 far from the end of the second through hole, when the rotating piece 32 pushes the latch tongue 31 to move rightwards, the rotating piece 32 rotates anticlockwise, and one end of the rotating piece can be accommodated in the opening, so as to prevent the accommodating cavity 12 from obstructing the movement of the rotating piece 32.

To sum up, the utility model provides an automatic bolt mechanism, install on passive fan, when the initiative fan is opened or is closed, the initiative fan collides with the bolt tongue and extrudes or breaks away from, bolt tongue lateral motion drives the rotor plate and pushes up or release downwards, bolt subassembly realizes rising certain height or descends certain height under return spring's effect to realize automatic locking or unblock process, can shorten the length of bolt subassembly, does benefit to the processing and the equipment of bolt subassembly, labour saving and time saving; the mechanism is provided with the screw rod with adjustable length, and can adjust the extension amount and the extension length of the latch pin assembly, thereby well meeting the requirements of door leaves with various sizes, in particular to an ultrahigh door.

The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
