Push-pull type bridge-cutoff aluminum alloy door and window

Abstract

The invention discloses a push-pull type bridge-cutoff aluminum alloy door and window. The push-pull type bridge-cutoff aluminum alloy door and window comprises a door and window frame, a sliding rail, a sliding door, a bottom end sliding groove, a top end sliding groove, a mounting hole, a movable hole, a positioning groove, a buffering device, a positioning device, a side groove, a guide groove, an adjusting block, a guide block, a mounting groove, a side hole, a fixing bolt and a threaded hole. When the sliding door makes contact with a buffering column, the sliding door can push the buffering column to move towards the interior of the movable hole, at the moment, a first type of spring can be compressed under the action of a limiting plate, meanwhile, a mounting block can slide along a mounting cavity, a buffering solution filled in the mounting cavity can be compressed into a buffering cavity, and therefore the sliding door is buffered; and otherwise, when the sliding door is separated from the buffering column, at the moment, the limiting plate can be pushed to move towards the outer end under the reaction of the first type of spring, meanwhile, the mounting block can be reset under the action of a threaded column, the buffering solution entering the buffering cavity can flow into the mounting cavity again, and therefore the buffering device can be repeatedly used.

Description

technical field [0001] The present application relates to a broken bridge aluminum alloy door and window, in particular to a push-pull broken bridge aluminum alloy door and window. Background technique [0002] The broken bridge aluminum alloy window is an improved type based on the old aluminum alloy window in order to improve the thermal insulation performance of doors and windows. As a whole, it forms a new heat-insulating aluminum profile, which can be divided into threading type and glue-injecting type according to its connection mode. Using this profile to make doors and windows has excellent heat insulation and completely solves the problem of aluminum alloy conduction. The fatal problem of fast heat dissipation and failure to meet energy-saving requirements, and at the same time adopt some new structural cooperation forms, completely solve the perennial problem of "aluminum sliding window is not tightly sealed". The product is made of aluminum on both sides, and the ...

AI Technical Summary

Problems solved by technology

[0003] The structure of the traditional broken bridge aluminum alloy doors and windows is generally relatively simple. When the doors and windows are pushed and pulled, it is easy to cause collisions between the doors, windows and the frame. When the impact is too large, it is easy to damage the doors and windows, reducing the service life of the broken bridge aluminum alloy doors and windows. Broken bridge aluminum alloy doors and windows usually need to be locked manually, which is cumbersome to use, and the traditional manual locking structure is easily damaged after long-term use, and its service life is limited
