Place the outer jacket frame at the installation position. Fill sealant four between the inner side surface of the outer jacket frame and the inner wall of the vehicle body, and fill sealant three between the outer side surface of the outer jacket frame and the outer wall of the vehicle body for sealing and fixing; Install the window glass into the inner sleeve frame, and install the angle aluminum fixing frame on the inner surface of the inner sleeve frame to limit the window glass. Sealant two is filled between the periphery of the window glass and the inner sleeve frame and the angle aluminum fixing frame for sealing and fixing. Place the assembled inner sleeve frame and window glass into the outer sleeve frame. Pass the installation screw one through the special-shaped rivet nut, vertical rib two, and vertical rib one to fasten the inner sleeve frame and the outer sleeve frame together. The plane of the special-shaped rivet nut is arranged adjacent to the inner surface of the outer sleeve frame. After the special-shaped rivet nut rotates, its plane contacts the inner surface of the outer sleeve frame to ensure the fastening of the installation screw one and the special-shaped rivet nut and prevent the inner sleeve frame from loosening during installation. Then, fill sealant one in the space surrounded by the outer side surface of the vertical rib one, the outer surface of the inner sleeve frame, and the outer wall of the vehicle body; Rotate the screw mechanism composed of the installation ratchet. The square nut moves towards the inner side wall of the vehicle body. The two ratchet mechanisms rotate towards the inner side wall of the vehicle body together under the action of the tooth grooves until the pressing blocks on the two ratchet mechanisms are pressed against the inner side wall of the vehicle body to achieve the fastening of the outer sleeve frame and the vehicle body and complete the installation of the window; A disassembly method for a high-speed EMU window with an anti-detachment structure. Use the above-mentioned high-speed EMU window with an anti-detachment structure. The steps are as follows: When the window glass has problems and needs to be replaced, the sealant one between the inner sleeve frame and the vehicle body can be removed from the outside of the vehicle body, and the installation screw one can be removed, then the inner sleeve frame and the window glass can be removed, and a qualified window glass and inner sleeve frame can be quickly replaced. After refilling the sealant one and the surface of the sealant one on the outside of the vehicle body is dry to the touch, the train can run without removing other components of the window and without waiting for the sealant one on the outside of the vehicle body to completely cure.

[0014] The installation ratchet assembly is installed on the outer sleeve frame. The installation ratchet assembly drives the ratchet mechanism and the pressing block to move through the screw mechanism, and clamps and fixes the outer sleeve frame to be flush with the outside of the vehicle body to install the window on the vehicle body without additional tooling. The I-shaped adjustment pad gives a supporting force to the outer sleeve frame during the adjustment of the installation ratchet to prevent the window glass from protruding outside the vehicle body.

[0015] The outer sleeve frame is provided with a special-shaped rivet nut. The special-shaped rivet nut is press-riveted on the outer sleeve frame. Its shape is that the head is a circular ring column with a threaded through hole inside, and the end is a large cylinder cut by two parallel planes to form two planes and two arc surfaces. Any one of the two planes is limited and fixed by the inner surface of the outer sleeve frame and cannot rotate, ensuring the connection fastening of the installation screw one and the special-shaped rivet nut.

[0016] The inner sleeve frame is provided with an inner and outer anti-detachment structure for the glass. The outer edge (outer side surface) of the aluminum profile on the outside of the inner sleeve frame prevents the glass from protruding outside the vehicle, and the angle aluminum fixing frame prevents the glass from protruding inside the vehicle, effectively ensuring the safety and stability of the glass and the window frame, and meeting the feasibility of the processing technology. Ensure the safety and stability of the train during high-speed operation.

[0017] When the window glass has problems and needs to be replaced, the sealant one can be removed from the outside of the vehicle, and the mounting screws two can be removed, then the inner sleeve frame, the window glass, the angle aluminum fixing frame, etc. can be removed, and a qualified inner sleeve frame and window glass can be quickly replaced. After applying the sealant one, when the surface of the sealant one on the outside of the vehicle body is surface dry, there is no need to disassemble other components inside the vehicle body, and there is no need to wait for the sealant one on the outside of the vehicle body to be completely cured. As long as the sealant one is surface dry, the train can run.

[0018] The window has high airtightness. The inner sleeve frame, the outer sleeve frame, the vehicle body and the window glass are all designed with an adhesive and sealed structure. After the sealant is adhesively cured, it can effectively prevent the gas flow inside and outside the vehicle body, improve the airtightness of the entire window, and also improve the airtightness of the entire vehicle.

[0019] Advantages of the present invention: 1. When the train is running at high speed, through the cooperation of the inner surface, the outer side surface of the inner sleeve frame and the angle aluminum fixing frame, the sealant two is adhesively bonded in a geometric structure with a cross-section similar to a concave shape around the outer edge of the window glass, so as to solve the potential danger of the glass falling out of the vehicle body under the condition of high external air pressure of the vehicle body and ensure the safe operation of the train; 2. The inner frame sleeve and the outer frame sleeve are connected by the mounting screws one and the special-shaped rivet nuts, and the sealant one is filled between the inner sleeve frame and the vehicle body in the direction of the outside of the vehicle body. When the window glass has problems and needs to be replaced, the sealant one between the inner sleeve frame and the vehicle body can be removed from the outside of the vehicle body, and the mounting screws one can be removed, then the inner sleeve frame and the window glass can be removed, so as to solve the trouble that the glass cannot be quickly replaced due to the breakage of the window glass and ensure that the train can run in time without being delayed in the time of replacing the glass.

[0020] 3. Since the window glass, the inner sleeve frame, the outer sleeve frame and the vehicle body are all adhesively sealed structures, the airtightness of the window and the vehicle body is effectively improved; 4. After the window is installed on the vehicle body, by rotating the screw mechanism, the window and the vehicle body can be quickly clamped and fixed without additional special installation tools, and the operation is reliable and effective.
