Description

Low-noise strong-sealing aluminum alloy door and window Technical Field The utility model relates to the technical field of aluminum alloy doors and windows, in particular to a low-noise strong-sealing aluminum alloy door and window. Background The aluminum alloy door and window is a door and window which is made of aluminum alloy extruded profiles as frames, stiles and sash materials, and is called as aluminum door and window for short. The aluminum alloy door and window has good corrosion resistance and weather resistance, can adapt to various climatic environments, is not easy to rust, and can ensure long-term normal use. The aluminum alloy doors and windows can be divided into sliding doors and windows and upper-suspended doors and windows according to different opening and closing modes, and the sliding doors and windows are horizontally sliding in the same plane, the upper-suspended doors and windows are fixed at the upper ends, the opening is inclined, and the opening is arranged below. From the two aspects of easy opening and no occupation of excessive space, the sliding doors and windows gradually become mainstream products in the field of decoration and building materials, and are increasingly favored by consumers. The push-pull type aluminum alloy door and window comprises a window frame and a door leaf arranged in the window frame, and the door leaf is horizontally pushed in a plane so as to open or close the door and window. However, in the actual door leaf opening and closing process, when the door leaf is opened and closed too fast by too strong force, severe collision can occur between the door leaf and the window frame, noise generated by collision is large, and when surrounding residents are influenced, the door leaf also has large damage risk. In order to alleviate the above-mentioned problem, some manufacturers can install the crashproof strip additional in the inboard of door leaf, the crashproof strip is made by rigid plastic or silica gel, rubber material, when door leaf collides with the crashproof strip, can reduce noise to a certain extent, the bottom fixed mounting that is located the inboard of window frame in the coplanar, when opening and shutting door and window, the lateral wall bottom of door leaf can directly collide with the crashproof piece, with the impact area of reduction door leaf, thereby noise reduction to a certain extent, however, no matter be the crashproof strip that rigid plastic or silica gel, rubber constitute, the door leaf is when colliding with it, the deformation of crashproof strip is limited relatively, it is difficult to guarantee the leakproofness between window frame and the door leaf, the sound insulation effect is not good. Therefore, there is a need for an improved structure of an aluminum alloy door and window to overcome the above problems. Disclosure of utility model The utility model aims to overcome the defects in the prior art and provide the aluminum alloy door and window with good sealing performance and low noise. The technical scheme includes that the low-noise strong-sealing aluminum alloy door and window comprises a window frame, a fixed door leaf and a movable door leaf, wherein the fixed door leaf is fixedly arranged in the window frame, sliding grooves on the upper side and the lower side and adapting grooves on the left side and the right side are formed in the window frame, the movable door leaf is located on the front side of the fixed door leaf and is slidably connected with the sliding grooves, an anti-collision strip made of elastic materials is fixedly arranged in the adapting grooves, a sealing cavity is formed in the anti-collision strip, filling gas is filled in the sealing cavity, a locking piece is movably inserted into one side, far away from the fixed door leaf, of the front surface of the window frame, a locking hole is formed in one side of the movable door leaf, corresponding to the locking piece, and the end portion of the locking piece can be inserted into the locking hole. Further, an inclined plane is arranged on one side, close to the locking piece, of the movable door leaf, the inclined plane can be abutted against the end portion of the locking piece, and an elastic piece is arranged between the locking piece and the window frame in a telescopic mode along the moving direction of the locking piece. Further, a fixing sleeve is fixedly installed on the window frame, one end of the fixing sleeve is opened, the locking piece movably penetrates through the fixing sleeve, an abutting edge is convexly arranged on the outer wall of the locking piece and located in the fixing sleeve, one end of the elastic piece abuts against the inner wall of the fixing sleeve, and the other end of the elastic piece abuts against the abutting edge. Further, the elastic piece is a spring sleeved outside the locking piece. Further, a limiting edge is arranged on the outer wall of the locking piece, located outside the fixing sleeve in
