Referring to fig. 2 to 3, the latch structure 100 according to the embodiment of the present invention includes a locking pin 120 connected to a doorframe 300, a latch 110 connected to an emergency exit 200, and a guide 130 connected to the doorframe 300 and located below the locking pin 120. Preferably, the guide 130 is spaced apart from the locking pin 120.

The locking member 110 has an unlocking position far from the locking pin 120 and a locking position locked with the locking pin 120, and the locking member 110 can reciprocate between the unlocking position and the locking position by opening and closing the safety door 200 toward the doorframe 300. Normally, when the emergency exit 200 is closed with the doorframe 300, the locking member 110 moves from the unlocking position to the locking position and is locked with the locking pin 120, at this time, the guide member 130 is attached to the lower edge of the locking member 110, when the emergency exit 200 is deviated downwards due to the gravity, the locking member 110 moves from the shackle position to the lower side of the locking position and is abutted against the guide member 130, and at this time, the guide member 130 can guide the locking member 110 to move upwards to the locking position, so that the locking member 110 is locked with the locking pin 120.

The utility model discloses a set up guide 130 and make emergency exit 200 when because dead weight skew downwards, hasp piece 110 can be raised to the lock position by guide 130, has just so realized the alignment of hasp piece 110 with locking pin 120 again to hasp piece 110 and locking pin 120 lock.

Referring to fig. 2 to 3, specifically, the locking member 110 is provided with a locking groove 111, and when the locking member 110 is located at the locking position, the locking pin 120 is inserted into the locking groove 111 to limit the displacement of the locking pin 120. Preferably, the locking groove 111 is provided with an upper edge of the locking member 110, so as to widen the alignment error between the locking groove 111 and the locking pin 120, and facilitate the fastening of the locking member 110 and the locking pin 120.

Referring to fig. 2 to 3, the locking pin 120 includes a slideway disposed on the door frame 300 and a bolt 121 slidably connected to the slideway, the bolt 121 has an avoiding position and a limiting position, the bolt 121 can move between the avoiding position and the limiting position, when the bolt 121 moves from the limiting position to the avoiding position, the bolt moves from the locking piece 110, the locking piece 110 can move to the fastening position, at this time, the bolt 121 moves from the avoiding position to the limiting position to be inserted into the locking groove 111, so as to realize the fastening of the locking piece 110 and the locking pin 120, when a door needs to be opened, the bolt 121 moves from the limiting position to the avoiding position, the locking piece 110 can be separated from the locking pin 120, and the safety door 200 can be opened. Preferably, the limiting position is located below the avoiding position to be matched with the position of the locking groove 111.

Referring to fig. 2, the locking pin 120 further includes an elastic member 122, one end of the elastic member 122 is connected to the door frame 300, and the other end is connected to the bolt 121, and the elastic member 122 has a compressed state generating an elastic restoring force when the bolt 121 moves from the retracted position to the advanced position and a released state releasing the elastic restoring force to move the bolt 121 from the advanced position to the retracted position. The elastic member 122 enables the locking pin 120 to have resilience force when moving from the avoiding position to the limiting position, so that the operation steps are saved, and the labor is saved.

Referring to fig. 2 to 3, specifically, the locking pin 120 further includes a limiting sleeve 123 and a handheld rod 124 connected to the plug 121, and the plug 121 and the elastic element 122 are sleeved in the limiting sleeve 123. The stop collar 123 provides a slide for the locking pin 120, prevents the bolt 121 from breaking away from the preset slide, and prevents the bolt 121 from being damaged or deformed by external collision. The hand-held lever 124 facilitates manipulation of the latch 121 by a user and facilitates adjustment of the position of the latch 121.

Alternatively, the guide 130 has a first chamfered surface facing the locking member 110, and the first chamfered surface can guide the locking member 110 to move upward to the locking position when interfering with the locking member 110. The first chamfered surface can provide an upward component force to the locking member 110 when abutting against the locking member 110, so as to lift the locking member 110 to the fastening position and fasten the locking pin 120.

Referring to fig. 2 to 3, preferably, the guide 130 is cylindrical and is rotatably connected to the door frame 300 by taking an axis thereof as a rotation axis. This reduces the frictional force between the locking member 110 and the guide member 130, so that the fastening process of the safety door 200 to the doorframe 300 is more labor-saving. Preferably, the guide 130 is a bearing and has a mounting flap 131 to prevent dislocation of the bearing.

Referring to fig. 2 to 3, preferably, the locking pin 120 has a second chamfered surface 1210 facing the locking member 110, and the locking member 110 can drive the plug pin 121 to move from the limiting position to the avoiding position when abutting against the second chamfered surface 1210. The locking pin 120 realizes self-locking through the second chamfered surface 1210, and a force towards an avoiding position can be applied to the locking pin 120 through the movement of the locking piece 110 without applying a force to the locking pin 120 by a user, so that the locking piece 110 can move to a locking position smoothly.

Referring to fig. 2 to 3, preferably, the locking element 110 has a third oblique surface 1101 facing the guide 130, and the third oblique surface 1101 is used for guiding the locking element 110 to move from the unlocking position to the locking position. The third inclined plane 1101 guides the locking element 110 so as to guide the locking element 110 to move upwards when abutting against the guiding element 130.

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.
