[0018] The following is a further detailed description of the specific implementation methods of the present invention by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of the present invention.

[0019] like Figure 1-4 As shown, the utility model provides a glass lifter detection silent room door lifting mechanism, including an opening and closing component 3 and a lifting component 4. The opening and closing components 3 are provided in two groups and are symmetrically arranged on both sides of the silent room 1 and are used to open and close the silent door 2 on the front side of the silent room 1. The lifting components 4 are provided in two groups and are symmetrically arranged on both sides of the silent room 1 and the silent door 2 and are used to lift and lower the silent door 2.

[0020] It should be noted that the opening and closing assembly 3 includes a movable frame 31 and an opening and closing cylinder 36. The movable frame 31 is an "H"-shaped structure and has two symmetrically provided slide rails 33 on both sides that are slidably connected to the two sliders 32 on the outside of the silent room 1. The movable frame 31 has two symmetrically provided slide rails 35 on both sides that are slidably connected to the slide rails 34 on the outside of the silent door 2. The cylinder body of the opening and closing cylinder 36 is installed on a bracket 37 on the outside of the silent room 1 and the end of its piston rod is connected to the movable frame 31.

[0021] In addition, the lifting assembly 4 includes a lifting cylinder 41, a chain 44, a weight 46 and a sprocket 47. The cylinder body of the lifting cylinder 41 is installed on the bracket 2 42 on the movable frame 31 and the end of its piston rod is provided with a fixed frame 43. The fixed frame 43 spans both sides of the slide rail 2 34 and is connected to the silent door 2. One end of the chain 44 is connected to the silent door 2, and the other end of the chain 44 is provided with a weight 46 that is slidably connected to the guide cylinder 45 on the silent room 1. The sprocket 47 is rotatably connected to the outside of the silent room 1 through the rotating shaft 471 and engages with the chain 44.

[0022] In addition, the silent room 1 is provided with a protective cover 48 on the upper side of the chain 44 and the sprocket 47 to protect the chain 44 and the sprocket 47 .

[0023] Specific implementation and principle:

[0024] Door opening process:

[0025] First, the piston rod of the opening and closing cylinder 36 is controlled to extend, driving the slide rail 33 on the moving frame 31 to move on the slider 32 on the silent room 1, driving the silent door 2 to separate a certain distance from the door frame; then, the piston rod of the lifting cylinder 41 is controlled to extend, and the chain 44 descends along the guide cylinder 45 under the drag of the weight 46, thereby causing the silent door 2 to open upward;

[0026] Closing process:

[0027] First, the piston rod of the lifting cylinder 41 is controlled to retract, and the weight 46 on the chain 44 is dragged along the guide cylinder 45 by the piston rod of the lifting cylinder 41, so that the silent door 2 moves downward; then, the piston rod of the opening and closing cylinder 36 is controlled to retract, driving the slide rail 33 on the movable frame 31 to move on the slider 32 on the silent room 1, driving the silent door 2 to separate and press together with the door frame without a gap.

[0028] To sum up, the present application drives the silent door 2 to be separated from the silent room 1 by a certain distance through the opening and closing cylinder 36 of the opening and closing component 3, and drives the silent door 2 to be lifted smoothly under the action of the lifting cylinder 41 of the lifting component 4 and the weight 46 on the chain 44. The weight 46 on the chain 44 also has an upward force on the silent door 2, so that the silent door 2 receives a double force, thereby improving the safety of the silent door 2 after lifting.

[0029] The above-described embodiments of the present invention do not limit the scope of protection of the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
