Internally dismantled anti-typhoon soundproof horizontal sliding window

An internally dismantled anti-typhoon soundproof horizontal sliding window comprising at least one outer sliding window and an inner sliding window in an interior of an outer frame body, the outer frame body guiding the at least one outer sliding window and the inner sliding window;

• the inner sliding window is composed of left and right columns and upper and lower horizontal members;
• the outer and inner sliding windows are composed of inner columns, outer columns and upper and lower horizontal members;
• wherein a snap hook device is respectfully installed on each of two vertically extending sides of the outer frame body to hold respective vertically extending sides of the at least one outer sliding window and the inner sliding window and enable the respective vertically extending sides of the outer and inner sliding windows to be tightened against the vertically extending sides of the outer frame body and control a relative tightness between an inner column of the at least one outer sliding window and an inner column of the inner sliding window;
• wherein the internally dismantled anti-typhoon soundproof horizontal sliding window includes a central control lock that causes a top plate arranged outside an outer casing to move inward, so as to push on a top of and clamp the at least one outer sliding window, thereby ensuring the sealing of the internally dismantled anti-typhoon soundproof horizontal sliding window, and
• wherein an outer side of the outer frame body is provided with an outer fixing post, an inner side of the outer fixing post is provided with the top plate, and the top plate includes a plurality of springs connected with the outer fixing post, so that the top plate is caused by the central control lock to move inward against an elastic force of the springs, and to return to an original position of the top plate by the elastic force of the springs upon release of the top plate by the central control lock.
