The utility model discloses a special tension locking mechanism for aluminum alloy push-pull doors and windows, which can make the sealing highly reliable, including a fixed frame and a push-pull fan, the push-pull fan is slidably arranged on the fixed frame, a sealing strip is arranged at the inner and outer positions of the profiles on both sides of the fixed frame, the inner fan frame and the outer fan frame of the push-pull fan respectively press the inner sealing strip and the outer sealing strip, and the inner side of the fixed frame is provided with a The lock seat is equipped with a lock point on the sliding side of the push-pull fan. The lock point is connected with the transmission rod in the push-pull fan, and the other end of the transmission rod is connected with the handle. The front end face of the lock point is a mushroom head structure. The lock seat is formed with a slot, which is divided into an insertion section and a tension section. The diameter of the slot insertion section is larger than that of the mushroom head at the lock point. The two sides of the slot tension section are inclined surfaces which are back against the push-pull fan The inclined plane climbs along the locking direction of the locking point, the mushroom head is inserted into the slot insertion section, and the umbrella bottom of the mushroom head is inclined to the two sides of the pressing slot.
【技术实现步骤摘要】
一种铝合金推拉门窗专用拉紧锁闭机构
:本技术涉及一种铝合金推拉门窗专用拉紧锁闭机构。
技术介绍
:推拉铝门窗为了提高水密性和气密性,在固定框两侧型材上分别设置了内密封条和外密封条,推拉扇的内扇框和外扇框在推拉扇关闭后,分别对压压住内密封条和外密封条,而在实际使用中,因传统的推拉铝门窗锁具只具有简单的锁紧作用,在推拉扇关闭上锁后,常常因密封条的弹性,导致推拉扇朝开启的方向稍微退回,引致密封效果相当差,甚至产生密封失效。
技术实现思路
:本技术的目的是为了克服上述现有技术的缺点,提供一种可使密封高度可靠的铝合金推拉门窗专用拉紧锁闭机构。本技术的专利技术目的可以通过以下的技术方案来实现:一种铝合金推拉门窗专用拉紧锁闭机构,包括有固定框和推拉扇,推拉扇滑配在固定框上,在固定框两侧型材的内侧和外侧位置处设置有密封条,推拉扇的内扇框和外扇框分别对压内密封条和外密封条,在固定框内侧面上设置有锁座,在推拉扇侧边上滑配有锁点,锁点与推拉扇内的传动杆连接,传动杆的另一端与手柄连接,锁点的前端面为蘑菇头结构,锁座内成型有插槽,插槽分为插入段和拉紧段,插槽插入段直径比锁点的蘑菇头直径大,插槽拉紧段的两侧面为背靠推拉扇的倾斜面,倾斜面沿锁点锁紧方向爬升,蘑菇头插进插槽插入段内,蘑菇头的伞底对压插槽两侧倾斜面。采用本技术方案后,与现有技术相比,本技术方案具有以下优点:锁点上的蘑菇头插进插槽内并在手柄转动时,拉动蘑菇头产生朝插槽拉紧段移动的动作,利用倾斜面产生对蘑菇头的逐渐拉紧紧锁作用,迫使推拉扇朝固定框侧边型材进 ...
