Description

Technical Field

[0002] Door and window sample corners are display products that allow buyers to understand the structure and materials of doors and windows most intuitively. They are divided into two types: fixed parts and opening parts. Generally, the door and window hardware is locked and opened by rotating the handle. The transmission converts the rotation of the handle square shaft into the axial displacement of the locking point on the transmission rod to achieve the coordination and separation of the locking point and the lock block. The display sample corners of the opening part need to display the cross-sectional structure of doors and windows and are often small in size. Generally, they cannot be locked by installing conventional door and window hardware. Generally, special structures are used for locking. For example, the frame and sash are respectively installed with N and S pole magnets to lock by magnetic attraction, or the frame and sash are respectively installed with retaining springs and locking points. When opening, it is necessary to use force to separate the two-pole magnets or retaining springs from the locking points. This process often causes the hand to collide with the sample corner section and get injured due to improper force. Utility Model Content

[0048] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention.

[0049] The utility model also has the following implementation methods based on the above:

[0050] In a further embodiment of the utility model, this structure utilizes the hardware U-groove space of the middle leaf of the sample corner, draws on the ratchet principle, and adopts a pressing method to control the displacement of the sample corner locking point. The same locking principle as the actual doors and windows allows the user to control the locking and opening of the sample corner in a more elegant and safer operation method.

[0051] In a further embodiment of the utility model, the installation method is as follows: the device is slid into the U groove along the U groove section of the sample corner fan profile hardware, so that the plane of the housing 1 on the side of the device with the ratchet pressure rod button 5 is flush with the U groove section of the fan profile hardware, and the device is fixed to the sample corner fan profile by bolts using the bolt holes 11 on the housing 1. The locking point 61 is switched to the open position by pressing the ratchet pressure rod button 5, and the position of the locking block is determined according to the position of the locking point 61, and the locking block is fixed to the sample corner frame profile by bolts.

[0052] In a further embodiment of the present invention, the method of use is as follows: by pressing the ratchet lever button 5, the locking point 61 is switched to the open position, such as Figure 1 and Figure 3 As shown, the ratchet lever button 5 pops out more, closing the sample angle fan; by pressing the ratchet lever button 5, the lock point 61 is switched to the locked position, as shown Figure 2 and Figure 4 As shown, the ratchet lever button 5 pops out less and the sample angle frame fan is locked; by pressing the ratchet lever button 5 to switch the locking point 61 to the open position, the sample angle fan can be opened.

[0053] In a further embodiment of the present invention, when the device is in the on state, Figure 1 and Figure 3As shown, by pressing the ratchet lever button 5, the ratchet lever button slider 51 moves along the slideway 21 of the sleeve 2, and at the same time pushes the ratchet lock 4 and the connecting rod 6 with a locking point to move. Due to the existence of the spring baffle 22 of the sleeve 2, the spring 3 is compressed. When the ratchet lock ratchet teeth 43 move to the end slope position of the slideway 21 of the sleeve 2, due to the friction force, the ratchet lock ratchet teeth 43 slide out of the slideway 21 of the sleeve 2. After the ratchet lock 4 rotates 45° around the axis as a whole, the ratchet lock ratchet teeth 43 are combined with the ratchet lever button ratchet teeth 52 of the ratchet lever button 5. At this time, stop pressing the ratchet lever button 5, the spring 3 is partially restored, and the ratchet lock ratchet teeth 43 are restricted by the locking point of the sleeve 2. At this time, the ratchet lever button 5, the ratchet locking member 4 and the connecting rod 6 with the locking point are displaced, and the locking point 61 moves from the open position to the locked position and slides into the locking block, and the device is in the locked state. Figure 2 and Figure 4 shown.

[0054] In a further embodiment of the present invention, when the device is in a locked state, Figure 2 and Figure 4 As shown, the ratchet lever button 5 is pressed, and the ratchet lever button slider 51 moves along the slideway 21 of the sleeve 2, while pushing the ratchet locking member 4 and the connecting rod 6 with a locking point to move. Due to the existence of the spring baffle 22 of the sleeve 2, the partially recovered spring 3 is compressed again. When the ratchet teeth 43 of the ratchet locking member move to the end position of the locking point slope of the sleeve 2, stop pressing the ratchet lever button 5, and the spring 3 recovers. Due to the friction force, the ratchet locking member 4 rotates 45° around the axis as a whole, and then the ratchet teeth 43 of the ratchet locking member are combined with the ratchet lever button ratchet teeth 52 of the ratchet lever button 5. The ratchet teeth 43 of the ratchet locking member slide into the slideway 21 of the sleeve 2 until they are restricted by the end of the slideway 21 of the sleeve 2. At this time, the displacement of the ratchet lever button 5, the ratchet locking member 4 and the connecting rod 6 with a locking point is completed, and the locking point 61 moves from the locked position to the open position, slides out of the lock block, and the working state of the device is in the open state, as shown in FIG. Figure 1 and Figure 3 shown.

[0055] In a further embodiment of the utility model, the U-groove hardware door and window corner locking device has a simple structure, is quick to install, is compatible with U-groove hardware, does not require re-opening of slot holes, is easy to operate, and will not cause harm to the operator.

[0056] In a further embodiment of the utility model, the U-groove hardware door and window corner locking device adopts a ballpoint pen cap, after which the pen tip moves out and limits the position, and the pen tip bounces back when the pen cap is pressed again. The structure and principle are applied to the locking of door and window hardware. The structure is simple, easy to process, and convenient to assemble and disassemble. It does not occupy the space of door and window frames and sashes, and can be directly assembled in the original installation position of the door and window hardware. It will not interfere with the opening and closing of the doors and windows. During the opening and closing process of the doors and windows, only the ratchet pressure rod button 5 needs to be pressed. The operation is simple and will not cause harm to the operator.

[0057] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
