Description

Technical Field

[0001] This utility model relates to the field of door and window locks, specifically a button-type door and window lock. Background Technology

[0002] As a key component in ensuring the safety of building doors and windows, door and window locks play a vital role in daily life. Through a specific mechanical structure, they tightly connect doors and windows to their corresponding frames, providing basic security for people's living environment, effectively preventing unauthorized entry by outsiders, and protecting the safety of people and property inside.

[0003] Currently, most door and window locks widely used in the market adopt a relatively traditional design, and their main working mechanism is to open and close the lock by rotating the handle. When the user rotates the handle, the connected mechanical structure will drive the lock block to move, thereby precisely locking the lock block into the pre-set lock groove in the door and window frame, completing the locking action of the door and window.

[0004] However, this seemingly simple and practical door and window lock design has a significant safety vulnerability. Since it can be opened simply by turning the handle, it is easy for some children to accidentally open the doors and windows without supervision, causing certain safety problems. Summary of the Invention

[0005] Therefore, the purpose of this utility model is to provide a button-type door and window lock to solve the technical problem that door and window locks are easily opened by children, causing certain safety hazards.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a button-type door and window lock, including a lock handle, a window body connected to one side of the lock handle, a fixing plate provided at one end of the window body, a rotating column connected to one side of the lock handle, a lock plate fixed to the outer wall of the rotating column, a fixing column provided inside the rotating column, a locking block movably installed on the outer wall of the fixing column, a third spring connected to one end of the locking block, the third spring initially being in a compressed state, a limit block fixed to one end of the fixing column, a limit groove opened inside the window body, a connecting column connected to one end of the fixing column, a first button installed at the end of the connecting column, a first spring sleeved on the outer wall of the connecting column, and the end of the first spring connected to the inner wall of the rotating column.

[0007] By adopting the above technical solution, the problem of door and window locks being easily opened by children, posing a certain safety hazard, is solved. After the window is closed and locked, the first button pushes the fixed column into the rotating column through the connecting column. When the fixed column moves to the end of the inner wall of the rotating column, the third spring, which is in a compressed state, presses the locking block upward against one side of the pressing plate, thereby fixing the fixed column. The limiting block at the end of the fixed column is embedded in the limiting groove inside the window body. The limiting block fixes and limits the lock handle, making it impossible for the lock handle to rotate, thus preventing children from turning the lock handle to open the window.

[0008] The present invention is further provided that the inside of the fixing plate is provided with a locking groove, and the bottom end of the inner wall of the locking groove is provided with an arc shape.

[0009] Preferably, the lock plate can be locked into the lock groove by rotating the lock handle. The bottom of the inner wall of the lock groove is arc-shaped, which allows the lock plate to be rotated into the lock groove.

[0010] The present invention is further configured such that both the limiting block and the limiting groove are square, and the dimensions of the limiting block and the limiting groove are the same.

[0011] Preferably, when the fixed column is displaced to the bottom of the rotating column, the limiting block is embedded in the limiting groove inside the window body. The limiting groove limits the rotating column through the limiting block, so that the rotating column cannot rotate.

[0012] The present invention is further configured such that a second button is installed on the outer wall of the rotating column, a push column is connected to one side of the second button, a pressing plate is fixed to the end of the push column, and a second spring is sleeved on the outer wall of the push column.

[0013] Preferably, pressing down on the second button causes the pusher to press the compression plate downwards. The downward-moving compression plate pushes the locking block into the fixed post. The first spring, which is in a stretched state, pulls the fixed post back to its initial position, and the limiting block moves along with the fixed post, thereby releasing the locking operation of the lock handle and making it convenient for personnel to unlock the lock handle.

[0014] The present invention is further configured such that a rotating disk is connected to the end of the rotating column, and the rotating disk is located inside the window.

[0015] Preferably, the rotating disk limits the rotation of the column so that the column does not detach from the window when it rotates.

[0016] The present invention is further configured such that a frame is fitted on the outer wall of the fixing plate, and the window is movably installed on the inner wall of the frame.

[0017] Preferably, the frame secures the fixing plate and the window, and the frame also protects the window, preventing external objects from bumping and damaging the corners of the window when it is closed.

[0018] In summary, the present invention has the following main advantages:

[0019] This invention solves the safety hazard caused by children easily rotating and opening door and window locks by incorporating a lock handle, rotating column, lock plate, fixed column, limiting block, first button, and locking block. After the window is closed and locked, the first button pushes the fixed column into the rotating column via the connecting column. When the fixed column moves to the inner end of the rotating column, the compressed third spring presses the locking block upward against one side of the compression plate, thus fixing the fixed column. The limiting block at the end of the fixed column is embedded in the limiting groove inside the window, fixing and limiting the lock handle so that it cannot be rotated, thereby preventing children from rotating the lock handle to open the window.

[0020] This utility model incorporates a first spring, a compression plate, a second spring, a third spring, and a second button. When the second button is pressed down, it pushes the compression plate downwards via a push post. The downward-moving compression plate pushes the locking block into the fixed post. The first spring, which is in a stretched state, pulls the fixed post back to its initial position, and the limiting block moves along with the fixed post, thus releasing the locking operation of the lock handle and facilitating the unlocking of the lock handle by personnel.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] Please see Figure 1 — Figure 5 The system includes a lock handle 1, a window 2 connected to one side of the lock handle 1, a fixing plate 3 at one end of the window 2, a rotating column 5 connected to one side of the lock handle 1, a lock plate 501 fixed to the outer wall of the rotating column 5, a fixing column 6 inside the rotating column 5, a latching block 8 movably mounted on the outer wall of the fixing column 6, a third spring 801 connected to one end of the latching block 8 (initially compressed), a limit block 601 fixed to one end of the fixing column 6, a limit groove 201 inside the window 2, a connecting column 602 connected to one end of the fixing column 6, a first button 604 mounted at the end of the connecting column 602, and a first button 604 sleeved on the outer wall of the connecting column 602. Spring 603, with its end connected to the inner wall of rotating column 5, solves the problem that door and window locks are easily opened by children, posing a certain safety hazard. After the window 2 completes the closing and locking operation, the first button 604 pushes the fixing column 6 into the rotating column 5 through the connecting column 602. When the fixing column 6 moves to the end of the inner wall of the rotating column 5, the third spring 801, which is in a compressed state, presses the locking block 8 upward to one side of the pressing plate 7, thereby achieving the fixing operation of the fixing column 6. The limiting block 601 at the end of the fixing column 6 is embedded in the limiting groove 201 inside the window 2. The limiting block 601 fixes and limits the lock handle 1, making the lock handle 1 unable to rotate, thereby preventing children from turning the lock handle 1 to open the window 2.

[0031] For details regarding the above embodiments, please refer to [link / reference]. Figure 2The fixed plate 3 has a locking groove 301 inside, and the bottom end of the inner wall of the locking groove 301 is set as arc. When the operator rotates the lock handle 1, the locking plate 501 can be snapped into the locking groove 301. The bottom end of the inner wall of the locking groove 301 is set as arc, so that the locking plate 501 can be rotated into the locking groove 301.

[0032] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 Both the limiting block 601 and the limiting groove 201 are set as squares, and the size of the limiting block 601 and the limiting groove 201 are the same. When the fixed column 6 is displaced to the bottom of the rotating column 5, the limiting block 601 is embedded in the limiting groove 201 inside the window 2. The limiting groove 201 limits the rotating column 5 through the limiting block 601, so that the rotating column 5 cannot rotate.

[0033] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 A second button 703 is installed on the outer wall of the rotating column 5. A push column 701 is connected to one side of the second button 703. A pressing plate 7 is fixed to the end of the push column 701. A second spring 702 is sleeved on the outer wall of the push column 701. When the second button 703 is pressed down, the second button 703 presses the pressing plate 7 down through the push column 701. The downwardly moving pressing plate 7 pushes the locking block 8 into the fixed column 6. The first spring 603, which is in a stretched state, pulls the fixed column 6 back to its initial position. The limiting block 601 moves with the fixed column 6, so that the limiting block 601 releases the locking operation of the lock handle 1, thereby facilitating the personnel to unlock the lock handle 1.

[0034] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 The end of the rotating column 5 is connected to a rotating disk 502, which is located inside the window 2.

[0035] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 A frame 4 is fitted on the outer wall of the fixing plate 3. The window 2 is movably installed on the inner wall of the frame 4. The frame 4 fixes the fixing plate 3 and the window 2, and the frame 4 can protect the window 2 to prevent external objects from bumping and damaging the corners of the window 2 when the window 2 is closed.

[0036] In practical operation, when the window 2 needs to be closed, firstly, rotate the lock handle 1 counterclockwise by 90 degrees, then flip the window 2 to one side of the fixing plate 3, and then rotate the lock handle clockwise by 90 degrees. The lock handle 1, through the rotating column 5, rotates and latches the lock plate 501 into the lock groove 301 inside the fixing plate 3, completing the closing and locking operation of the window 2. Then, press the first button 604. The first button 604, through the connecting column 602, pushes the fixing column 6 into the rotating column 5. During the movement of the fixing column 6, the fixing column 6 pulls the first spring 603. When the fixing column 6 moves to the end of the inner wall of the rotating column 5, the third spring 801, which is in a compressed state, will... The locking block 8 presses upward against one side of the pressing plate 7, thereby fixing the fixing post 6. The limiting block 601 at the end of the fixing post 6 is embedded in the limiting groove 201 inside the window 2, so that the limiting block 601 fixes and limits the lock handle 1. When the window 2 needs to be opened, the second button 703 is pressed down. The second press 703 pushes the pressing plate 7 downward through the pushing post 701. The downward moving pressing plate 7 pushes the locking block 8 into the fixing post 6. The first spring 603, which is in a stretched state, pulls the fixing post 6 back to its initial position, and the limiting block 601 moves with the fixing post 6, thereby releasing the locking operation of the locking block 601 on the lock handle 1.
