Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of door and window components, in particular to an up-and-down linkage latch for a driven leaf of an aluminum-clad wooden door. Background Art
[0002] Doors are used more frequently than windows as a companion product to windows in the building's exterior envelope. The quality of doors directly affects their service life, and the most important component affecting the door's opening and closing is the hardware that supports the connection between the door frame and the leaf. In the long-term use of doors, due to the wear, deformation, and displacement of hardware, the door leaf may lose corners, be poorly sealed, fall off, or have locking problems. At this time, the above problems will be solved by adjusting the hardware, so the quality and function of the hardware are crucial to the use of the door.
[0003] With the increase in large-sized apartments, the openings are getting bigger and bigger. Single-door openings can no longer meet the requirements of large openings. There are more and more double-door openings. The active and passive doors can be opened at the same time to broaden the field of vision and increase ventilation. At the same time, it is convenient to carry large household appliances and furniture. However, the biggest problem with double-door openings is that there has been no comfortable solution for the locking of the passive fan itself. Since most active fans are directly locked on the passive fan, the locking quality of the passive fan directly affects the locking of the active fan, and also affects the watertightness, airtightness, wind pressure resistance and anti-theft performance of the entire door. At present, the most common solution for passive fan locking is the upper and lower heaven and earth pin locking. The biggest disadvantage of this is that the upper and lower parts are not connected, the closing is controlled separately, and the upper and lower parts are not unified. Once the door leaf is installed irregularly, the upper and lower parts of the door leaf are not centered, and it is difficult to lock it. When the height exceeds a certain size, it is difficult for people standing on the ground to reach the upper side latch. If you want to open the door leaf, you have to raise your feet to operate the opening and closing, which is very inconvenient. Utility Model Content

[0037] In a further embodiment of the present invention, Figure 3 The present invention is an installation example of the upper and lower linkage latches of the master and slave leaves of an aluminum-clad wooden door. In this example, the passive leaf 9 and the active leaf 10 are locked together by the intermediate transfer material 7. The transfer material 7 and the passive leaf 9 are tightly fixed together by screws. The upper and lower linkage latches are installed in the transfer material slot cavity. The upper and lower linkage latches are embedded in the cavity fork between the transfer material 7 and the passive leaf 9 to drive the upper and lower linkage steel rods 5. By shifting the linkage handle on the linkage latch body 1, the linkage handle consists of a linkage wrench 2 and a rotating push piece 3, which can control the steel rod 5 to shrink and release simultaneously in the cavity. When the steel rod 5 shrinks, the parts of the steel rod 5 that leak out of the upper and lower sides of the leaf are separated from the upper and lower frame latch slots. At this time, the passive leaf 9 is opened. When the steel rod 5 is released, the parts of the steel rod 5 that leak out of the upper and lower sides of the leaf enter the upper and lower frame latch slots. At this time, the passive leaf 9 is in a locked state.

At this time, the steel rod 5 is located in the pin block 6, and the passive fan 9 is in a locked state; when the linkage wrench 2 and the linkage bolt body 1 reach 90 degrees, the two fork sliders 41 slide to the nearest low point in the two main body slide grooves 14 respectively, the distance between the two fork sliders 41 is the smallest, and the linkage fork 42 drives the steel rod 5 to retract the maximum displacement. At this time, the steel rod 5 is separated from the pin block 6, and the passive fan 9 is in an open state.
[0041] In a further embodiment of the utility model, the utility model realizes the upper and lower locking linkage of the passive leaf 9, and the opening and closing of the passive leaf 9 of the door leaf is controlled by the rotation of the linkage wrench 2.

[0044] In a further embodiment of the utility model, the steel rod 5 has high rigidity and strength, which can ensure the performance of the door and further ensure the safety and anti-theft performance.
[0045] In a further embodiment of the utility model, each fork slider 41 is installed in a main body slide groove 14, and the fork slider 41 is limited by the main body slide groove 14, so that the sliding path of the fork slider 41 is only located in the main body slide groove 14, thereby preventing the fork slider 41 from detaching from the linkage pin body 1.
[0046] In a further embodiment of the utility model, when the linkage wrench 2 is rotated to a position perpendicular to the linkage pin body 1, the distance between the two fork sliders 41 is the smallest, and the two steel bars 5 are separated from the two pin blocks 6 on the frame 8, so that the passive fan 9 is in an open state, and the passive fan 9 can move in the frame 8.
