Abstract

本实用新型涉及一种机械闭门器,属于一种门控五金件。在U型支臂的U型槽内装有拉簧,拉簧一端由调节螺栓与U型支臂的下端固定连接、另一端与功能板连接,该功能板上分别有扣锁槽、90度定位槽、180度定位槽,功能板另一端透过U型底部的长槽与拉杆铰接,滚轮固定在支臂U型槽内,该功能板与滚轮滚动连接,该拉杆的一端与支臂铰接、另一端与固定脚铰接,U型支臂下部与固定板铰接。优点在于结构新颖,使用方便,造价低,寿命长。

Description

机械闭门器
技术领域
本实用新型属于一种门控五金件。
背景技术
目前普遍使用的闭门器均为油压式的,它存在的问题是;由于加工精度高,导致成本高,而且易损坏,寿命低,开门时扭力逐渐加大,不方便使用。
发明内容
本实用新型提供一种机械闭门器,以解决目前油压式闭门器存在的成本高、易损坏、寿命低、不方便使用的问题。本实用新型采取的技术方案是:在U型支臂的U型槽内装有拉簧,拉簧一端由调节螺栓与U型支臂的下端固定连接、另一端与功能板连接,该功能板上分别有扣锁槽、90度定位槽、180度定位槽,功能板另一端透过U型底部的长槽与拉杆铰接,滚轮固定在支臂U型槽内,该功能板与滚轮滚动连接,该拉杆的一端与支臂铰接、另一端与固定脚铰接,U型支臂下部与固定板铰接。
使用时,当门在0-20度间开启时,由于扣锁槽的杠杆作用,闭门的力量很大;当门开至20-85度间时闭门的力量相对很小;当门开至90度及180度时,定位槽与滚轮相齿合,门便达到定位的功能。调节螺栓对拉簧的调节,可以改变闭门的力度。
本实用新型的优点在于结构新颖,使用方便,造价低,寿命长。
附图说明
图1是本实用新型结构示意图。
具体实施方式
在U型支臂1的U型槽内装有拉簧2,拉簧一端由调节螺栓3与U型支臂的下端固定连接、另一端与功能板4连接,该功能板上分别有扣锁槽5、90度定位槽6、180度定位槽7,功能板另一端透过U型底部的长槽与拉杆8铰接,滚轮9固定在支臂U型槽内,该功能板与滚轮滚动连接,该拉杆的一端与支臂铰接、另一端与固定脚10铰接,U型支臂下部与固定板11铰接。
