Description

Technical Field

[0001] The invention relates to a lock body, in particular to a lock body for a casement sliding door or window and the sliding door or window. Background Art

[0002] In daily life, the use of sliding doors and windows has become very common. As a kind of decorative doors and windows that are essential for modern home decoration, sliding doors and windows can greatly improve the utilization rate of indoor space compared with ordinary rotating doors and windows because they are opened by sliding. However, since ordinary sliding doors and windows cannot be fully opened, the passage position is limited. People hope to combine sliding doors and windows with casement and rotating doors and windows, so that they can not only achieve sliding and half-opening doors and windows, but also achieve fully opening doors and windows after casement and rotation. When realizing doors and windows that can be pushed and pulled and can be fully opened by casement and rotation, the sliding track of the sliding doors and windows includes two parts: one part is a fixed track fixed to the upper part of the door and window frame, and the other part is a moving track fixed to the top of the fixed door and window frame. Since the sliding doors and windows must slide to the moving track with the help of the fixed track, they can overlap with the fixed doors and windows and rotate. This requires that a special lock body must be designed on the fixed track and the moving track to allow the sliding doors and windows to slide smoothly from the fixed track to the moving track.

[0003] In order to solve the above problems, there is such a design in the prior art: patent application number 2016102318145, application publication number CN105715132A, application publication date June 29, 2016, invention name "A lock body and sliding door and window". The specific content of the prior art is: a lock body, including a lock buckle and a lock buckle matching part, the lock buckle includes a lock tongue, a lock buckle body and a first pulley hole of the lock body, the lock tongue extends into the first pulley hole of the lock body, the lock buckle matching part includes a blocking piece and a second pulley hole of the lock body, the blocking piece is used to compress and block the lock tongue, the lock tongue has grooves on both sides, the end of the groove away from the first pulley hole of the lock body is provided with a first buckle, the lock buckle body is provided with a protrusion, the groove matches the protrusion, and the first buckle matches the protrusion. When realizing doors and windows that can be pushed and pulled and opened horizontally, the lock tongue on the lock buckle can block the pulley of the sliding door and window when the door and window are opened horizontally, preventing the sliding door and window from sliding out of the track. At the same time, when closing the door and window, the lock tongue can release the slideway after being compressed from bottom to top, so that the pulley of the sliding door and window can be pushed and pulled through the track to achieve the purpose of closing the door and window. The defects of the prior art are that the lock tongue can only be compressed horizontally and must be used with a blocking piece. The blocking piece of the lock buckle matching part must be higher than the position of the inclined surface of the lock buckle matching part. Before the lock tongue touches the blocking piece, when the lock tongue is higher, it is very easy for the lock tongue to touch the end of the lock buckle first, which will affect the closing of the door panel. In addition, the lock body and sliding door and window of the prior art can only be used for single-leaf movable doors, and a reset spring must be used. Therefore, the application environment is subject to certain limitations and the structure is relatively complex. Summary of the invention

[0004] In order to overcome the shortcomings of the prior art, the present invention is an improvement on the above-mentioned lock body and sliding doors and windows, with the aim of providing a lock body with a wider applicable environment and a simpler structure. The lock body can block the sliding of the sliding doors and windows when the doors and windows are opened, preventing the sliding doors and windows from sliding out of the track. Moreover, when the doors and windows are closed, the lock body can release the door panel, allowing the sliding doors and windows to be pushed and pulled through the door panel cavity to achieve the purpose of closing the doors and windows.

DETAILED DESCRIPTION

[0024] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1 and Figure 2 As shown, the overall structural diagram and the matching structural diagram of the lock body of Example 1 of the present invention.

[0026] The casement sliding door and window comprises a door and window body (not shown in the figure), a first door panel cavity 15, and a third door panel cavity 16, in which the door panel slides back and forth. The first door panel cavity 15 and the third door panel cavity 16 are arranged on a first tapping mechanism 1, and the first tapping mechanism 1 can move together with the sliding track fixed on the door panel. In addition, the sliding track fixed on the door frame cannot be moved. A second tapping mechanism 2 is arranged at the end of the sliding track, and a second door panel cavity 25 and a fourth door panel cavity 26 are designed on the second tapping mechanism 2. The first door panel cavity 15 matches the second door panel cavity 25, and the third door panel cavity 16 matches the fourth door panel cavity 26, so that the door panel can slide in the door panel cavity. The lock body includes a first branching mechanism 1 and a second branching mechanism 2 matched with the first branching mechanism 1, wherein the first branching mechanism 1 includes a support rod 11, a lock tongue 12, a slideway 13 and a stop groove 14, and the second branching mechanism 2 includes an arc 21, a platform 22 and a stop protrusion 24, wherein the support rod 11 is fixedly connected to the lock tongue 12, the support rod 11 can slide freely in the slideway 13, the stop groove 14 is matched with the stop protrusion 24, the arc 21 is inclined from bottom to top, and the arc 21 The highest end of the slide 13 smoothly transitions with the platform 22; when the second branch mechanism 2 and the first branch mechanism 1 move toward each other and finally merge into one, the support rod 11 runs from the lowest end of the arc 21 to the platform 22, and the lock tongue 12 is compressed from bottom to top; when the second branch mechanism 2 and the first branch mechanism 1 move away from each other and finally separate completely, the support rod 11 runs downward from the platform 22 through the highest end of the arc 21 until it leaves the arc 21, and the lock tongue 12 is released. The axis of the slide 13 forms an angle of 60 degrees with the horizontal line of the lock body. A reset spring (not shown in the figure) is also provided on the upper part of the slide 13; a reset spring (not shown in the figure) is also provided at the bottom of the stop protrusion 24.

[0027] like Figure 2 As shown, when the first branch mechanism 1 gradually approaches the second branch mechanism 2 until they are flush, the support rod 11 first contacts the lowest end of the arc 21, then gradually ascends along the smooth arc surface to the highest end of the arc 21, and finally stops on the platform 22. During the operation, the lock buckle 12 which is integral with the support rod 11 is also gradually ascended, releasing the sliding cavity, that is, the first door panel cavity 15 and the third door panel cavity 16, so as to facilitate the sliding of the sliding door and window and achieve the purpose of closing the door and window. A stopper is provided on the door panel matched with the first door panel cavity 15. When sliding, the door panel slides into place and then drives another door panel. When opening, the same principle applies.

[0028] like Figure 3 , Figure 4 , Figure 5As shown, a schematic diagram of the first tapping mechanism and the second tapping mechanism of the lock body of Example 1 of the present invention. When closing the door and window, the two door panels slide in the fixed track fixed on the door frame, and one end of the fixed track on the door frame is provided with a second tapping mechanism. The second tapping mechanism 2 is provided with a corresponding second door panel cavity 25 and a corresponding fourth door panel cavity 26. The second door panel cavity 25 is communicated with the first door panel cavity 15, and the fourth door panel cavity 26 is communicated with the third door panel cavity 16. After the two door panels are returned to their positions (i.e., the door and window are pushed open horizontally, and the three door panels are combined into one), the second tapping mechanism 2 and the first tapping mechanism 1 begin to move in opposite directions, and the first tapping mechanism 1 is finally completely separated. At this time, the support rod 11 runs downward from the platform 22 through the highest end of the arc 21 until it leaves the arc 21, and the lock tongue 12 is released. The door and window are rotated to open the lock tongue 12 body, which can block the door frame after the door and window are opened, and prevent the sliding door and window from sliding out of the track, thereby achieving the purpose of opening the door and window.

[0030] Figure 7 Schematic diagram of the first tapping mechanism of the lock body of Example 2 of the present invention.

[0031] Figure 8 This is a schematic diagram of the first tapping mechanism of the lock body of Example 2 of the present invention (the other side).

[0032] Fig. 9 Schematic diagram of the second tapping mechanism of the lock body of Example 2 of the present invention.

[0033] In the sliding door and window of this embodiment, the first branching mechanism of the lock body only has the first door panel cavity 15 but no third door panel cavity 16 , and correspondingly, the second branching mechanism only has the second door panel cavity 25 but no fourth door panel cavity 26 . The lock body of Example 2 includes a first branching mechanism 1 and a second branching mechanism 2 matched with the first branching mechanism 1. The first branching mechanism 1 includes a support rod 11, a lock tongue 12 and a slide 13. The second branching mechanism 2 includes an arc track 21 and a platform 22. The support rod 11 is fixedly connected to the lock tongue 12, and the support rod 11 can slide freely in the slide track 13. The arc track 21 is inclined from bottom to top, and the highest end of the arc track 21 smoothly transitions with the platform 22. When the second branching mechanism 2 and the first branching mechanism 1 move toward each other and finally merge into one, the support rod 11 runs from the lowest end of the arc track 21 to the platform 22, and the lock tongue 12 is compressed from bottom to top. When the second branching mechanism 2 and the first branching mechanism 1 move away from each other and finally separate completely, the support rod 11 runs downward from the platform 22 through the highest end of the arc track 21 until it leaves the arc track 21, and the lock tongue 12 is released.

[0034] The slideway 13 of this embodiment forms an angle of 70 degrees with the horizontal line of the lock body, so that when the first branch mechanism and the second branch mechanism move in opposite directions, the support rod 11 and the lock tongue 12 can slide down by their own gravity, and no return spring is required to be installed in the slide, which further simplifies the lock body structure.

[0035] The present invention can realize the step-by-step operation of the rotation and translation of doors and windows, and can limit the relatively sliding doors and windows within the range of the track width without the doors and windows being derailed and separated. In addition, the sliding effect and space utilization are increased, so that multiple doors and windows can slide in sequence. The number of doors and windows can be adjusted according to the actual environment. Even two door panel cavities are allowed to install only one door panel. The lock body improvement of the present invention can realize the full opening of multiple doors and windows.

[0036] Although the invention has been disclosed as above in terms of preferred embodiments, the embodiments and drawings are not intended to limit the invention. Anyone familiar with the art can make various changes or modifications without departing from the spirit and scope of the invention, but they are also within the scope of protection of the invention. Therefore, the scope of protection of the invention shall be based on the scope of protection of the claims of this application.
