Description

Door and window sealing structure
Technical Field
The invention relates to the technical field of door and window sealing, in particular to a sealing structure for a sliding door or a lifting door or window.
Background
The sliding door and the lifting door and window, the sealing problem of the sliding direction edges of the sash and the frame, because the sliding needs to slide on the frame to realize the functions of opening the sash and closing the sash, the traditional sliding has the following solving methods for solving the sealing problem of the moving edges of the sash and the frame:
1. the wool tops are arranged on the push-pull fan, the structure does not influence the push-pull operation force of the fan because of small resistance of the wool tops, but the wool-shaped structure of the wool tops can not effectively prevent wind and rain from entering a room, and the structure is the worst sealing solution in the push-pull structure.
2. The wool tops of the push-pull fan are replaced by low-resistance adhesive tapes to realize sealing, the adhesive tapes cannot be excessively pressed and can only be slightly lapped, the excessive pressing amount can cause the fan to slide, the push-pull force of the braking phenomenon is large and cannot be normally used, the fan can be normally pushed and pulled and can only be slightly pressed, and the capacity of preventing wind and rain from entering a room by slightly pressing is limited.
3. The whole fan is lifted by the complicated hardware transmission mechanism, so that the adhesive tape and the frame are separated, the resistance of the adhesive tape is avoided during pushing and pulling, and the adhesive tape pressing frame is lowered by the hardware transmission to achieve sealing when the fan is to be closed.
4. The top wool or the adhesive tape is not arranged between the push-pull fan and the frame, so that the push-pull is not subjected to resistance, when the fan is closed, the four sides of the whole fan are tensioned to the frame through the hardware transmission mechanism, so that the adhesive tape of the fan and the frame form a seal, the hardware of the mechanism can translate and pull the whole fan to the frame for sealing only by changing the force for many times to reach the four sides, the hardware transmission is extremely complex, the manufacturing cost is high, and the market acceptance is very low.
5. The fan adhesive tape is made into the adhesive tape of a sealing body, the adhesive tape is inflated into the adhesive tape through the air pump to realize the sealing with the frame, the sealing of the adhesive tape can not be damaged and air leakage is guaranteed when the fan adhesive tape is used, one push-pull stroke needs to be flushed and deflated once, the fan adhesive tape can be normally used only when the fan adhesive tape is required to be electrified, and the market application is very few.
The principle and structure of the push-pull show that when the push-pull fan is pushed and pulled, the adhesive tape vertical to the movement direction of the fan can be pressed by the force of the movement of the fan, and the sealing in the same direction with the push-pull of the fan cannot be contacted due to the movement of the adhesive tape, and the push-pull of the fan can be influenced by too large friction resistance, so that the sealing problem in the same direction as the push-pull of the fan is not well solved in the prior art.
