Description

Technical Field

[0001] The utility model relates to the technical field of door and window lock structures, in particular to a window lock mechanism and a window body. Background Art

[0002] The sliding door comprises a fixed wing leaf and a movable wing leaf, both of which are arranged parallel to the window frame. A handle is arranged on the movable wing leaf, which is used to push the movable wing leaf on the one hand and to lock the movable wing leaf on the other hand after the movable wing leaf is pulled to a specified position.

[0003] A locking structure is provided inside the movable wing leaf, which is connected to the handle through a transmission box. The movable hook of the existing locking structure is generally designed to be small, and the openings and inlets on the fixed wing leaf and the movable wing leaf are also small, which easily leads to two problems:

[0004] 1. If the openings on the fixed wing leaf and the movable wing leaf do not correspond slightly, it will affect the assembly of the locking structure, and high processing accuracy is required;

[0005] 2. The hook is small, and the contact area with the fixed wing is small, resulting in stress concentration and easy damage after long-term use. Utility Model Content

The sliding bar is located behind the fixed part, and its rear end is connected to the transmission bar, and its front end is connected to the sliding plate. The sliding plate is located in the accommodating hole, and its vertical dimension is smaller than the vertical length of the accommodating hole. An S-shaped groove is vertically opened in the sliding plate, and the two end points of the S-shaped groove are respectively located at the lower left and upper right of the sliding bar. An annular sleeve is provided in the S-shaped groove, and the limit member is connected to the annular sleeve through a first connecting member.

[0025] As a preferred embodiment, the width of the S-shaped groove is the same at all places and is arranged through the slide plate, which can not only facilitate the movement of the annular sleeve, but also reduce the friction between the annular sleeve and the slide plate or the sliding bar.

[0026] Limiting platforms are respectively arranged at the two ends of the front of the sliding bar, a vertical slideway is arranged between the two limiting platforms, the fixing parts are slidably connected to the two sides of the sliding bar, and a boss is arranged at the rear end of the sliding plate, which is connected in the slideway.

On the other hand, there is no need to consider processing errors and the assembly is simplified. No matter how it is installed, there will always be a large contact area between the extrusion plate 101 and the hook 7.

[0051] See also Figure 5-Figure 7The transmission unit includes a handle, a transmission box and a transmission bar 1. The transmission bar 1 is arranged vertically, and the upper end is connected to the direction-changing unit. By rotating the handle, the power is transmitted to the transmission bar 1 through the transmission box, and the transmission bar 1 moves vertically and can drive the direction-changing unit to move vertically. As for the transmission unit part, it is similar to the prior art, and the specific structure is not repeated.

[0054] The limiting member 4 is vertically arranged on the inner side of the front end surface of the fixing member 8 , and the upper and lower ends are connected to the extension portion 81 of the fixing member 8 through the connecting pin 5 .

[0055] The connecting pin 5 is arranged transversely, and the transverse sliding distance of the limiting member 4 on the connecting pin 5 is greater than the maximum distance between the opposite surfaces of the hook 7 and the extrusion plate 101 .

[0056] The front of the limiting member 4 is connected to the hook 7 , and the rear is connected to the direction-changing unit via the first connecting member 33 .

[0057] Under the action of the direction-changing unit, the limiting member 4 can move laterally in the fixing member 8 along the direction of the connecting pin 5 .

[0058] As one of the embodiments, the limit member 4 includes a U-shaped member, and a connecting plate 6 is arranged at the front opening position. The size of the connecting plate 6 is smaller than the width of the hook 7, and it is welded at the opening of the limit member 4. The surface is flush with the U-shaped opening of the limit member 4, and a mounting hole is opened at the center line position. The hook 7 is connected to the connecting plate 6 through a second connecting member 71.

[0059] The second connecting member 71 can be a bolt, and a transverse sliding groove is provided on the hook 7 to facilitate adjustment of the installation position of the hook 7 during assembly.

[0060] See also Figure 8 The fixing member 8 has a receiving hole 82 between the two end extensions 81 for connecting the direction changing unit. The receiving hole 82 is a rectangular hole.

[0061] Further, the direction-changing unit includes a sliding bar 2 and a slide plate 3. A groove is vertically provided at the rear of the fixing member 8. The front of the sliding bar 2 is slidably connected to the groove at the rear of the fixing member 8. The rear end thereof is connected to the transmission bar 1, and the front end is connected to the slide plate 3. The slide plate 3 is located in the receiving hole 82, and the vertical dimension is smaller than the vertical length of the receiving hole 82. An S-shaped groove 31 is vertically provided in the slide plate 3. The two ends of the S-shaped groove 31 are respectively located at the lower left and upper right of the sliding bar 2. An annular sleeve 32 is provided in the S-shaped groove 31. The stopper 4 is connected to the annular sleeve 32 through a first connecting member 33. The first connecting member can be a bolt structure, the rear end round head is stuck in the annular sleeve 32, and the front end threaded section is connected to the rear end of the stopper 4.

[0062] As a preferred embodiment, the width of the S-shaped groove is the same at all places and is arranged through the slide plate 3. This can facilitate the movement of the annular sleeve 32 and reduce the friction between the annular sleeve 32 and the slide plate 3 or the sliding bar 2.

[0063] Limiting platforms 21 are respectively provided at the two ends of the front of the sliding bar 2, and a vertical slideway 22 is provided between the two limiting platforms 21.

[0068] When it is necessary to lock the movable wing sash 9, the window locking mechanism of the movable wing sash 9 is pushed to be aligned with the extrusion plate 101 of the fixed wing sash 10, and then the handle is turned to drive the transmission bar 1 to move upward through the transmission box. The transmission bar 1 drives the slide plate 3 from the bottom end of the accommodating hole 82 to the top position. At the same time, the vertical displacement of the limit member 4 is locked by the connecting pin 5, and its lower end is connected to the annular sleeve 32 through the first connecting member 31. When the vertical displacement of the annular sleeve 32 is limited, it slides from the upper right along the S-shaped groove 31 to the lower left, and at the same time drives the limit member 4 to slide to the left end position along the connecting pin 5, and the hook 7 connected thereto is released from the extrusion plate 101 to the left, thereby realizing the locking of the movable wing sash 9 and the fixed wing sash 10.
