The utility model discloses a three-section guide rail, which comprises an upper rail, a middle rail and a fixed rail; the middle rail is rolled and installed on the fixed rail; the upper rail is rolled and installed on the middle rail; the features are as follows: a counterweight structure is also included; a pressing opening is arranged on the top wall of the upper rail, and the side wall of the pressing opening is inclined downward to form a clamping part; and the top of the counterweight structure is protruded. The pressing part is inserted into the pressing mouth, and the pressing part is provided with a clamping groove with an upper opening and a side opening. The clamping groove is assembled with the clamping part card. The utility model realizes that the counterweight structure is mounted on the upper rail through the clamping groove and the clamping part, and when it needs to be disassembled, the clamping part is pressed downward through the pressing mouth, so that the clamping part can be separated from the clamping groove, thus realizing the disassembly of the counterweight structure, which is more convenient to disassemble and assemble than the fixed way of tape, glue, nails, etc.
【技术实现步骤摘要】
一种三节导轨
本技术涉及一种导轨,尤其涉及一种三节导轨。
技术介绍
目前,三节导轨在使用时候,上轨作为活动轨需要往外拉,但是,当上轨滑出的部分比较多时,由于力臂变长,使得上轨有轻微的倾斜,而影响了三节导轨使用的顺滑度,降低三节导轨的使用寿命;故多通过增加上轨后端的厚度来提高其后端的重量,或者在上轨固定一重物,以达到防止倾斜的作用,但是,现有的重物需要采用胶带、胶水、钉子等方式固定,拆装复杂。
技术实现思路
为了克服现有技术的不足,本技术的目的在于提供一种三节导轨,其通过卡装槽、卡装部、按压口和按压部的配合,以便于拆装。本技术的目的采用以下技术方案实现:一种三节导轨,包括上轨、中轨和固定轨;所述中轨滚动安装在所述固定轨;所述上轨滚动安装在所述中轨上;还包括配重结构,所述上轨的顶壁开设有按压口,所述按压口的侧壁倾斜向下延伸形成有卡装部;所述配重结构顶部凸出有穿插于所述按压口内的按压部;所述按压部开设有具有上开口和侧开口的卡装槽;所述卡装槽与所述卡装部卡装配合。进一步地,所述卡装部为卡装片。进一步地,所述上轨包括顶板和两挡板,所述挡板由所述顶板的侧边向下延伸形成;所述配重结构位 ...
