The invention discloses a convenient and safe pull-rod schoolbag, which comprises a schoolbag, the outer and bottom of which are embedded with a fixing block, a hook is arranged on the fixing block, and the hook is clamped with a card hole in the front groove of the bracket plate. The two sides of the hook are symmetrically arranged with a fixed end of the card belt, and the card passes through a corresponding hole in the middle of the bracket plate. The back side of the bag is provided with a rod barrel, the outer rod is sleeved with an outer rod connecting base, and the base In the bracket, gears are set at intervals between the two sides of the inner pole, and the inner pole is set in the outer pole. The lower surface of the bracket symmetrically connects the front roller and the back roller, and the upper end of the inner pole connects the handle. The bracket has compact structure and reasonable design. It is easy to clean, easy to assemble and disassemble, quick and not cumbersome. It also can eliminate accidents and avoid students'accidents in the inner pole. Pull out the danger of tripping and falling, in addition, the lower end of the backstrap of the schoolbag is equipped with elastic belt, which helps to lift the schoolbag and prevent students from hunching.

一种便捷安全型拉杆书包
本专利技术涉及学习用品
,特别是涉及一种便捷安全型拉杆书包。
技术介绍
书包,是指用布、皮革等制成的袋子。学生用来携带课本、文具用品。根据消费者品位的改变,书包发展出了一种更能减轻学生负担的书包。2014年新上市了一种万用拉杆书包,这种拉杆书包设计更加人性化,随着人们生活和消费水平的不断提高,各种各样的箱包已经成为人们身边不可或缺的饰品。人们要求箱包产品不仅在实用性上有所加强,装饰性也要有所拓展,慢慢的发展出现在的拉杆书包。拉杆书包都是连体式的,连体式拉杆书包所存在的缺陷有拆卸不方便、书包很容易脏,雨雪过后,书包就脏兮兮的。
技术实现思路
本专利技术的目的是针对现有问题,提供了一种便捷安全型拉杆书包。本专利技术是通过以下技术方案实现的:一种便捷安全型拉杆书包,包括书包,所述书包的外底面前侧对称嵌接固定块,固定块上一体且对称设置卡钩,卡钩卡接托板前侧凹槽内的卡孔,书包的外底面中间两侧对称设置卡带固定端,卡带穿过托板中间相应的条孔,书包的外底面后侧对称设置杆筒,杆筒套装外杆,外杆下端连接底座,底座通过螺钉固接于托板后侧,外杆内壁下端连接拉簧一端,其另一端连接内杆的内槽上端,内杆的两侧面内均间隔设置齿轮,齿轮的齿牙啮合外杆内壁上设置的齿条,内杆套设在外杆内,托板的下表面前侧和后侧均对称连接前支块和后滚轮,内杆上端连接拉手。作为对上述方案的进一步改进,所述的书包背带上端设有松紧带。作为对上述方案的进一步改进,所述的内杆的结构为工字形,其前后两面设置的内槽内装设拉簧,其左右两侧面上通过销轴间隔设置若干齿轮,齿轮的一侧表面凸出内杆的侧面并与外 ...
