TECHNICAL FIELD
[0001] The application relates to the technical field of door and window locks, and in particular to an aluminum alloy door and window lock. BACKGROUND
[0002] Doors and windows are divided into envelope components or partition components according to their positions, have different design requirements and are required to have functions such as heat preservation, heat insulation, sound insulation, waterproofing and fireproofing, and new requirements for energy saving. In cold regions, heat loss through door and window gaps accounts for about 25% of the total heating heat consumption. The requirement for the airtightness of doors and windows is an important content in energy-saving design. Doors and windows are important components in the building envelope structure system.
[0003] However, in actual application, most of the existing aluminum alloy doors and windows are usually opened or closed in a handle rotating manner, but this door and window opening and closing manner is relatively single, and children who lack safety awareness are likely to accidentally touch the handle to open the door and window, which is prone to cause danger and is not conducive to popularization and use.
[0004] Therefore, the person skilled in the art provides an aluminum alloy door and window lock to solve the problems in the background art. CONTENT OF THE INVENTION
[0005] In order to solve the problems in the background art that the door and window opening and closing manner is relatively single, children who lack safety awareness are likely to accidentally touch the handle to open the door and window, which is prone to cause danger and is not conducive to popularization and use, the application provides an aluminum alloy door and window lock.
[0006] The aluminum alloy door and window lock provided by the application adopts the following technical scheme: a lock cover is provided, a lock sleeve in transmission with a lock tongue body is rotatably connected to the right side of the lock cover, a transmission circular block is movably installed on the inner wall of the lock sleeve, a lock handle is fixedly connected to the right side of the transmission circular block, an arc-shaped transmission block is slidably connected to the right side of the lock sleeve and the left side of the lock handle, a limiting pin is fixedly connected to the top side of the arc-shaped transmission block, and a plug hole is formed in the bottom side of the lock sleeve and the bottom side of the transmission circular block.
[0007] Preferably, a plurality of ball grooves are formed in the outer side of the transmission circular block, a plurality of rolling balls are movably installed on the inner walls of the ball grooves, and the rolling balls are in contact with the inner wall of the lock sleeve.
[0008] Preferably, a limiting pin is fixedly connected to the left side inner wall of the lock sleeve, a limiting pin groove is formed in the left side of the transmission circular block, and the limiting pin is slidably connected to the inner wall of the limiting pin groove.
[0009] Preferably, a plurality of anti-skid sleeves are fixedly sleeved on the outer side of the lock handle.
[0010] In summary, the present application includes the following beneficial technical effects:
[0011] 1. By setting the limit pin, when the lock is opened and closed, the user manually holds the lock handle and pushes the arc-shaped transmission block upward with the index finger of the dominant hand. When the arc-shaped transmission block moves, it drives the limit pin to move upward. The limit pin after moving will be inserted into the inside of the two insertion holes. At this time, when the lock handle is twisted, the lock handle drives the arc-shaped transmission block to rotate synchronously under the cooperation of the limit pin and the insertion hole. The arc-shaped transmission block drives the lock sleeve to rotate synchronously. In this way, the lock can be opened and closed. Conversely, when the child twists the lock handle, the lock handle will be in an idle state because the limit pin is in a disengaged state with the insertion hole, thereby avoiding the child from opening the lock.
[0012] 2. By setting the ball, when the lock sleeve and the transmission block are installed, the plurality of balls can support between the two, and at the same time, the friction between the two can be reduced, avoiding the transmission of the lock sleeve and the transmission block due to excessive friction when the limit pin is not inserted into the insertion hole.
