[0025] A door and window sealing structure, which comprises a mounting frame 1, a first window frame 2 and a second window frame 3 are movably installed on the inner wall of the mounting frame 1, glass blocks 4 are fixedly installed on the inner walls of the first window frame 2 and the second window frame 3, mounting clamping grooves 5 are formed on the upper and lower sides of the first window frame 2 and the second window frame 3, a mounting shell 211 is fixedly installed at one end of the first window frame 2, a cavity 216 is formed in the inner wall of the mounting shell 211, a movable mechanism is arranged in the cavity 216, a first pressure triangular plate 219 is arranged on the movable mechanism, and a second pressure triangular plate 311 is fixedly installed on the outer surface of one side of the second window frame 3.

[0026] Further, the movable structure comprises two groups of mounting seats 212, and the two groups of mounting seats 212 are fixedly installed at the upper and lower ends of the cavity 216; circular through grooves are formed in the outer surfaces of the two groups of mounting seats 212, and a lead screw 217 is movably installed in the circular through grooves; a sliding seat 215 is movably installed on the outer surface of the lead screw 217; two groups of movable plates 218 are movably installed on the inner wall of the sliding seat 215; one end of each group of movable plates 218 is connected with the first pressure triangular plate 219; and the sliding seat 215 can stably move along the lead screw, so that the position and pressure of the first pressure triangular plate 219 can be accurately controlled.

[0027] Further, one end of the lead screw 217 is connected with a knob 213, the knob 213 is easy to operate, and a user can easily adjust the sealing degree of the window frame without using tools, so that the convenience in use is improved.

[0028] Further, the other end of each group of movable plates 218 is connected with a pull plate 214, the design of the pull plate 214 enables a user to conveniently initialize the position of the movable plate, so that the knob adjustment is prepared for subsequent operation, and the flexibility in operation is improved.

[0029] Further, one side of each of the first window frame 2 and the second window frame 3 is fixedly installed with a sealing rubber strip 6, the sealing rubber strip 6 can effectively fill the tiny gap between the window frame and the mounting frame 1, so that the sealing effect is enhanced, and the penetration of air, moisture and noise is prevented.

[0030] Further, the outer surfaces of the first pressure triangle 219 and the second pressure triangle 311 are wrapped with rubber, and the elasticity of the rubber can increase the friction between the pressure triangles and improve the tightness of the seal.

[0031] Further, the outer surface of the knob 213 is jagged, so that the user can more easily exert force when rotating the knob, preventing adjustment errors caused by slipping and improving the stability and accuracy of the operation.

[0032] Working principle: In the operation process of the door and window sealing structure, when the first window frame 2 and the second window frame 3 need to be closed to achieve the sealing effect, first ensure that one end of the two is in contact with each other. Then, manually operate the pull plate 214, which is connected to the movable plate 218, to cause the movable plate 218 to move outward. This action drives the displacement of the first pressure triangle 219, causing it to gradually approach and eventually be positioned above the second pressure triangle 311.

[0033] Next, use the knob 213 as an adjustment tool, one end of which is connected to the lead screw 217. By rotating the knob, the lead screw rotates in the circular groove, and its threaded structure causes the sliding seat 215 to move downward along the lead screw. As the sliding seat descends, the first pressure triangle 219 also descends and exerts pressure on the second pressure triangle 311, forming a preliminary contact state.

[0034] As the sliding seat 215 continues to move, the contact point between the first pressure triangle 219 and the second pressure triangle 311 gradually undergoes relative displacement, i.e., a "offset" pressing effect is formed between the two. This design not only enhances the tightness between the window frames, but also, under the combined action of the first pressure triangle 219 and the second pressure triangle 311, one end of the first window frame 2 and the second window frame 3 is firmly pressed against the mounting frame 1, thereby compressing the sealing rubber strip 6 installed on the edge of the window frame. The deformation of the sealing rubber strip fills the small gap between the window frame and the mounting frame, thereby achieving excellent sealing effect and effectively blocking the outside air, moisture and noise from entering the indoor space.

[0035] It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, from any point of view, the embodiments should be considered as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be considered as limiting the claims involved.
