Lock body and sliding door and window

[0025] [Example 1]

[0026] Such as figure 1 with figure 2 As shown, the overall structure diagram and the mating structure diagram of the lock body of Embodiment 1 of the present invention.

[0027] The flat sliding door and window include a door window (not shown in the figure), a first door panel cavity 15, and a second door panel cavity 16. The door panel slides back and forth in the two door panel cavities. The first door panel cavity 15 and the second door panel cavity 16 are arranged on the first tapping mechanism 1. The first tapping mechanism 1 can move along with the sliding track fixed on the door panel. In addition, the sliding track fixed on the door frame The track is not movable. The end of the sliding track is provided with a second tapping mechanism 2. The second tapping mechanism 2 is designed with a first door panel cavity 25, a second door panel cavity 26, a first door panel cavity 15 and a first door panel cavity 25 is matched, the second door panel cavity 16 and the second door panel cavity 26 are matched, and the sliding of the door panel in the door panel cavity can be realized with each other. The lock body includes a first tapping mechanism 1 and a second tapping mechanism 2 that cooperates with the first tapping mechanism 1. The first tapping mechanism 1 includes a support rod 11, a lock tongue 12, a slideway 13, and The stop groove 14, the second tapping mechanism 2 includes an arc 21, a platform 22 and a stop protrusion 24, the support rod 11 is fixedly connected to the lock tongue 12, and the support rod 11 can slide in the It slides freely in the channel 13, the stop groove 14 matches the stop protrusion 24, the arc channel 21 is inclined from bottom to top, and the highest end of the arc channel 21 is smooth with the platform 22 Transition; when the second tapping mechanism 2 and the first tapping mechanism 1 move towards each other and finally merge into one, at this time the support rod 11 runs from the lowest end of the arc 21 to the platform 22 , The lock tongue 12 is compressed from bottom to top; when the second tapping mechanism 2 and the first tapping mechanism 1 move away from each other and are finally completely separated, at this time the support rod 11 is removed from the platform 22 It passes through the highest end of the arc 21 and runs downward until it leaves the arc 21, and the lock tongue 12 is released. The axis of the sliding 13 and the horizontal line of the lock body form an angle of 60 degrees. The upper part of the slideway 13 is also provided with a return spring (not shown in the figure); the bottom of the stop protrusion 24 is also provided with a return spring (not shown in the figure).

[0028] Such as figure 2 As shown, when the first tapping mechanism 1 is gradually approaching the second tapping mechanism 2 until it is level, the support rod 11 first contacts the lowest end of the arc 21, and then gradually ascends to the arc 21 along the smooth arc. The highest end of the, finally stays on the platform 22, and during the operation process, the lock 12 that is integral with the support rod 11 is gradually raised, releasing the sliding cavity, that is: the first door panel cavity 15 and the second door panel cavity 16. It is convenient to realize the sliding of sliding doors and windows and realize the purpose of closing doors and windows. The door panel to which the first door panel cavity 15 fits is provided with a stopper. When sliding, the door panel slides into place before driving another door panel. The same principle applies when it is turned on.

[0029] Such as image 3 , Figure 4 , Figure 5 As shown, a schematic diagram of the first tapping mechanism and the second tapping mechanism of the lock body of Embodiment 1 of the present invention. When closing doors and windows, the realization is that the two door panels slide through the fixed rails fixed on the door frame. One end of the fixed rail on the door frame is provided with a second tapping mechanism, and the second tapping mechanism is provided with a corresponding first door panel. The cavity 25 and the corresponding second door panel cavity 26. The first door panel cavity 25 communicates with the first door panel cavity 15, and the second door panel cavity 26 communicates with the second door panel cavity 16. After the two door panels return to their positions (that is, the doors and windows are pushed open, three The door panels are united), the second tapping mechanism 2 and the first tapping mechanism 1 start to move backwards, and the first tapping mechanism 1 is finally completely separated. At this time, the support rod 11 passes through the highest end of the arc 21 from the platform 22 Run down until it leaves the arc 21, the lock tongue 12 is released, the door and window rotating opening lock tongue 12 body can block the door frame after the door and window are opened, avoid sliding the door and window from the track, and realize the purpose of opening the door and window.

[0032] Figure 7 It is a schematic diagram of the first tapping mechanism of the lock body in Embodiment 2 of the present invention.

[0033] Figure 8 It is a schematic diagram (the other side) of the first tapping mechanism of the lock body of Embodiment 2 of the present invention.

[0034] Picture 9 It is a schematic diagram of the second tapping mechanism of the lock body in Embodiment 2 of the present invention.

[0035] In the sliding door and window of this embodiment, the first tapping mechanism of the lock body only has the first door panel cavity 15 without the second door panel cavity 16. Correspondingly, the second tapping mechanism also has only the first door panel cavity 25, without The second door cavity 26. The lock body of embodiment 2 includes a first tapping mechanism 1 and a second tapping mechanism 2 that cooperates with the first tapping mechanism 1. The first tapping mechanism 1 includes a support rod 11, a lock tongue 12 and a slideway 13 , The second tapping mechanism 2 includes an arc 21 and a platform 22, the support rod 11 is fixedly connected with the lock tongue 12, the support rod 11 can slide freely in the slide 13, the arc 21 is inclined from the bottom to the top, and the arc 21 When the second tapping mechanism 2 and the first tapping mechanism 1 move towards each other and finally merge into one, the support rod 11 moves from the lowest end of the arc 21 to the platform 22 at this time, The lock tongue 12 is compressed from bottom to top; when the second tapping mechanism 2 and the first tapping mechanism 1 move back and are finally completely separated, the support rod 11 passes from the platform 22 through the highest end of the arc 21 Run down until it leaves the arc 21 and the bolt 12 is released.

[0036] The slideway 13 of this embodiment and the horizontal line of the lock body are at an angle of 70 degrees, so that when the first tapping mechanism and the second tapping mechanism move backwards, the support rod 11 and the lock tongue 12 can slide down by their own gravity. There is no need to install a return spring inside. The structure of the lock body is further simplified.

[0037] The invention can realize the step-by-step rotation and translation of doors and windows, and at the same time, it can limit the relatively sliding doors and windows within the range of the track width without derailing and separating the doors and windows. In addition, the sliding effect and space utilization are increased, so that multiple doors and windows can be used. Glide in sequence. The number of doors and windows can be adjusted according to the actual environment. Even the installation of only one door panel for the two door panel cavities is allowed. The improved lock body of the present invention can realize full opening of multiple doors and windows.
