Description

一种建筑工程用梯子 技术领域
本发明涉及建筑用工具技术领域，具体为一种建筑工程用梯子。
 背景技术
众所周知，在建筑工程中，梯子使用非常广泛，人字梯更为常用。人字梯：用于在平面上方空间进行装修之类工作的一类登高工具。因其使用时，前后的梯杆及地面构成一个等腰三角形，看起来像一个“人”字，因而把它形象的称为“人字梯”。人字梯一般由两片可相对转动的梯架构成，能够折叠，占地小，便于收纳，重量轻，移动方便，使用时将两片梯架展开呈人字形，无需倚靠在其他物件上就可以使用，另外，对于部分底面无法满足人字梯展开放置的条件时，可以将人字梯折叠成一字梯进行使用，但是在市面上，可以形成一字梯的人字梯大部分都是维持了原本人字形时候的高度，就算超过了原本的高度，在其固定效果亦不是很好。
 技术问题
为解决以上问题，本发明提供了一种建筑工程用梯子，能够在人字梯和一字梯之间互换，并且在切换成一字梯时，在获得比人字梯更高的高度的同时，具有良好的结构强度。
 技术解决方案
为实现上述目的，本发明提供如下技术方案：一种建筑工程用梯子，包括主梯、副梯、连接杆和固定杆，主梯包括多个梯杆和对称固定在梯杆两端的第一支撑杆，第一支撑杆一侧设有暗槽，副梯包括多个梯杆和对称固定在梯杆两端的第二支撑杆，第二支撑杆靠近主梯一侧的底端设有固定块，固定块可与暗槽固定连接，连接杆一端与第一支撑杆设有暗槽相邻一侧的一端转动连接，连接杆另一端与第二支撑杆滑动连接，固定杆一端与第一支撑杆顶端转动连接，另一端可固定于第二支撑杆顶端。
优选地，第二支撑杆轴向设有滑轨，连接杆包括滑动端，滑动端与滑轨滑动连接。
优选地，滑轨包括上卡槽和下卡槽，滑动端可分别卡接于上卡槽和下卡槽之间。
优选地，暗槽设有第一暗槽和第二暗槽，第一暗槽底部与第二暗槽顶部相连接，固定块可卡入第一暗槽内，且滑动于第一暗槽和第二暗槽内。
优选地，还包括固定件，第一暗槽下端设有第一固定孔，固定件可与第一固定孔固定连接，滑轨靠近下卡槽一端设有第二固定孔，固定件可与第二固定孔固定连接。
 有益效果
本发明提供的一种建筑工程用梯子，包括主梯、副梯、连接杆和固定杆，主梯包括多个梯杆和对称固定在梯杆两端的第一支撑杆，第一支撑杆一侧设有暗槽，副梯包括多个梯杆和对称固定在梯杆两端的第二支撑杆，其中梯杆的数量由实际使用到人字梯的高度来衡量，第二支撑杆靠近主梯一侧的底端设有固定块，固定块可与暗槽固定连接，连接杆一端与第一支撑杆下端转动连接，另一端与第二支撑杆的下端滑动连接，固定杆一端与第一支撑杆顶端铰接，另一端可与第二支撑杆顶端卡接。该建筑工程用梯子，能够在人字梯和一字梯之间互换，并且在切换成一字梯时，在获得比人字梯更高的高度的同时，具有良好的结构强度。。

 本发明的实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
参阅附图1-附图7，本发明公开一种建筑工程用梯子，包括主梯1、副梯2、固定杆4和连接杆5，主梯1包括多个梯杆3和对称固定在梯杆3两端的第一支撑杆11，第一支撑杆11一侧设有暗槽111，副梯2包括多个梯杆3和对称固定在梯杆3两端的第二支撑杆21，其中梯杆3的数量由实际使用到人字梯的高度来衡量，第二支撑杆21靠近主梯1一侧的底端设有固定块211，固定块211可与暗槽111固定连接，连接杆5一端与第一支撑杆11下端转动连接，另一端与第二支撑杆21的下端滑动连接，固定杆4一端与第一支撑杆11顶端铰接，另一端可与第二支撑杆21顶端卡接。
基于上述方案，该建筑工程用梯子具有两种形态：人字梯和一字梯。当固定杆4与第二支撑杆21顶端固定连接，连接杆5远离第一支撑杆11一端在第二支撑21杆上滑动至连接杆5与地面平行时，该建筑工程用梯子为人字梯形态。当固定杆4脱离第二支撑杆21，并转至与第一支撑杆11同一轴向时，再者，将整个副梯2向主梯1方向移动，由于连接杆5的作用，副梯2会被提起，且副梯2底部的固定块211会嵌入暗槽111内，该建筑工程用梯子形成一字梯状态。该建筑工程用梯子，能够在人字梯和一字梯之间互换，并且在切换成一字梯时，在获得比人字梯更高的高度的同时，具有良好的结构强度。
参阅附图5、附图6和附图7，第二支撑杆21轴向设有滑轨212，连接杆4包括滑动端51，滑动端51与滑轨51滑动连接。
进一步的，滑轨212包括上卡槽2121和下卡槽2122，且分别设置在两端，滑动端51可分别卡接于上卡槽2121和下卡槽2122，当滑动端51在与上卡槽2121卡接时，该建筑工程用梯子为一字梯形态；当滑动端51在与下卡槽2122卡接时，该建筑工程用梯子为人字梯形态。
参阅附图3和附图4，暗槽111设有第一暗槽1111和第二暗槽1112，第一暗槽1111底部与第二暗槽1112顶部相连接，固定块211可卡入第一暗槽1111内，且滑动于第一暗槽1111和第二暗槽1112内，当其固定块211底部与第二暗槽1112底部贴合时，该建筑工程用梯子为一字梯形态。
为了人字梯折叠时可有良好的固定效果，人字梯还包括固定件6，第一暗槽1111下端设有第一固定孔12，固定件6可与第一固定孔12固定连接，滑轨212靠近下卡槽2122一端设有第二固定孔22，固定件6可与第二固定孔22固定连接，当建筑工程用梯子为一字梯形态时，固定件6与第一固定孔12固定连接，且在固定件6的作用下，副梯2与主梯1牢固的贴合在一起，使得一字梯形态下固定强度增强，当建筑工程用梯子为人字梯时，固定件6与第二固定孔22固定连接，且在固定件6的作用下，连接杆5的滑动端51与下卡槽2122固定连接，使得人字梯形态下固定强度增强。
