Problems solved by technology

[0002] When the push-pull sash is opened and closed, in the relative movement between the frame and the sash, there are both the rolling of the pulley and the frictional movement between the sealing strip and the profile. The greater the friction force, the tighter the seal at the gap, and the tighter the seal. The opening and closing of the sash The greater the force, to ensure the opening and closing force, you have to reduce the tightness of the seal, which will inevitably lead to a decrease in air tightness, which is not conducive to energy saving

Abstract

The invention provides a lifting push-pull sealing rubber strip. The sealing ring comprises a body. The body comprises an installation part, a sealing part and a lip edge; the installation part, the sealing part and the lip edge are of an integrated structure,; V-shaped installation grooves are formed in the upper side and the lower side of the installation part; the sealing part is a plane; the body is provided with a cavity; and the lip edge extending outwards is arranged above the right side of the body. The sealing structure has the beneficial effects that the sealing effect of doors and windows is improved, the tightness is reduced, smooth opening and closing of window sashes are guaranteed, the structure is simple, and installation is convenient.

Description

Technical field [0001] The invention belongs to the technical field of door and window seals, and in particular relates to a lifting, pushing and pulling sealing rubber strip. Background technique [0002] When the sliding window sash is opened and closed, the relative movement of the frame and the fan includes both the rolling of the pulley and the frictional movement of the sealing strip and the profile. The greater the friction, the tighter the seal at the gap and the tighter the sealing. The greater the force, to ensure the opening and closing force, the tightness of the seal must be reduced, which will inevitably lead to a decrease in air tightness, which is not conducive to energy saving. Therefore, it is necessary to develop a lifting push-pull sealing strip, which can not only improve the sealing performance but also reduce the tightness, and ensure the smooth opening and closing of the window sash. Summary of the invention [0003] Based on the shortcomings of the above ...
