Description

一种发条内置于上梁的发条卷取装置 技术领域
本实用新型涉及窗帘技术领域，尤其涉及一种发条内置于上梁的发条卷取装置。
背景技术
现有的弹簧卷帘器，一般包括两侧的支架以及卷轴，并且在卷轴内设置有弹簧棒，弹簧棒上套接有限位弹簧，并在限位弹簧端部安装弹簧尾塞。限位弹簧的回弹力是根据窗帘的大小和重量提前旋转上力，但是这种结构的弹簧棒回弹圈数有限，并且回弹力也不均衡，想要更多的回弹圈数和更均衡的回弹力就需要更长的弹簧棒，但是更长的弹簧棒无法放入小面幅的窗帘。
针对上述技术问题，专利授权公告号为CN 210508989U的一种手托发条卷帘，包括左支架、右支架，以及连接左支架和右支架的挂架，在左支架和右支架之间设置右卷轴，卷轴上设置有卷帘，左支架和/或右支架上设置有用于转动卷轴以及卷取卷帘的发条卷取装置，通过在左支架、右支架内安装有卷取装置，卷取装置内设置发条弹簧，实现了扭力的预设，可调节卷轴收缩的扭力。
但是，上述专利还存在如下问题：由于发条弹簧安装在左支架的侧壁、右支架的侧壁上，且发条弹簧本身具有一定的宽度，因此，左支架、右支架在宽度方向更大，所以，当用户需要窄边支架的产品时，上述结构无法满足用户的需求。
实用新型内容
本实用新型针对现有技术中的不足，提出一种发条内置于上梁的发条卷取装置，将现有技术中左支架和/或右支架设置成水平部和竖直部的结合，然后将卷取装置安装在水平部内，可使得左支架和/或右支架竖直部的宽度大大减少， 以满足用户对窄边支架的产品需求。
为了解决上述技术问题，本实用新型通过下述技术方案得以解决：一种发条内置于上梁的发条卷取装置，包括上梁、支架、所述支架上安装有用于带动卷帘收卷和展开的卷轴，所述支架包括与所述上梁的布置方向一致的水平部和与所述上梁的布置方向垂直的竖直部，还包括安装在所述水平部内的卷取装置，所述卷取装置包括

进一步优化，所述支架包括左支架和右支架，所述卷取装置安装在所述左支架内的所述水平部内和/或所述右支架内的所述水平部内。
进一步优化，所述调节柱塞与所述卷取盘同轴连接。
进一步优化，所述传动结构为齿轮传动或带传动连接。
进一步优化，所述卷取盘同轴连接有第一齿轮，所述支架内安装有第二齿轮和第三齿轮，所述第三齿轮与所述卷轴同轴连接，所述第一齿轮与所述第二齿轮啮合，所述第二齿轮与所述第三齿轮啮合。
进一步优化，所述卷取盘同轴连接有第一卷带盘，所述支架内安装第二卷带盘，所述支架内还安装有定滑轮，所述第一卷带盘和所述第二卷带盘之间连接有皮带，所述皮带通过所述定滑轮改变所述皮带的方向。
进一步优化，所述调节柱塞包括螺纹柱，所述螺纹柱的一端设置有螺头，所述螺纹柱上螺纹连接有调节螺母，所述调节螺母与所述螺头之间连接有弹簧。
进一步优化，带有所述卷取装置的所述水平部的上表面还安装有盖板，所 述盖板上设有调节孔，所述螺头露出所述调节孔设置。
本实用新型的有益效果在于：1、将现有技术中左支架和/或右支架设置成水平部和竖直部的结合，然后将卷取装置安装在水平部内，可使得左支架和/或右支架竖直部的宽度大大减少，以满足用户对窄边支架的产品需求。
2、调节柱塞安装在水平部内，而卷轴安装在竖直部上，水平部和竖直部垂直安装设置，通过调节柱塞与卷轴之间可采用齿轮传动或带传动的方式，可实现调节柱塞与卷轴之间的传动，传动效果佳，使得卷轴带动窗帘收卷更加平稳。
3、其中卷帘的下端设置有配重块，通过配重块的重力与发条弹簧的扭力两者力平衡的作用使得用户下拉卷帘时能够停止至任意位置保持平衡。当出现发条弹簧的扭力不足或过多的现象时，通过对螺头旋紧或放松的调节，可实现对发条弹簧的扭力的调节，以使预设好的扭力与配重块的重力达到力平衡的状态，用户下拉卷帘时能够停止至任意位置。

本实用新型的实施例1提供一种发条内置于上梁的发条卷取装置，包括上梁1、支架2、所述支架2上安装有用于带动卷帘收卷和展开的卷轴3，所述支架2包括与所述上梁1的布置方向一致的水平部201和与所述上梁1的布置方向垂直的竖直部202，还包括安装在所述水平部201内的卷取装置，所述卷取装置包括
发条弹簧4、固定盘5和卷取盘6，所述发条弹簧4在松弛状态下套接于所述固定盘5上，所述发条弹簧4的卷取端与所述卷取盘6卡接；
调节柱塞7，所述调节柱塞7的一端与所述卷取盘6传动连接，所述调节柱塞7的另一端与所述卷轴3通过传动结构连接，所述传动结构位于所述竖直部202内。
其中，水平部201和竖直部202为一体设置，即支架2的截面为L型，安装在上梁1的两端。
固定盘5是用于安装发条弹簧4的，发条弹簧4的卷取端是与卷取盘6卡接的，通过将固定盘5内的发条弹簧4卷取至卷取盘6，或者将卷取盘6内的发 条弹簧4的卷取端回卷至固定盘5内，从而达到发条弹簧4收紧或放松的目的，以实现不同扭力的预设，发条弹簧4的预设扭力与配重块的重力达到平衡的状态，以实现用户下拉卷帘时能够停止至任意位置。
所述支架2包括左支架203和右支架204，所述卷取装置安装在所述左支架203内的所述水平部201内和/或所述右支架204内的所述水平部201内。

如图1-3、5所示，带有所述卷取装置的所述水平部201的上表面还安装有盖板15，所述盖板15上设有调节孔16，所述螺头12露出所述调节孔16设置。
调节孔16的设置，使得螺头12露出，用户操作螺头12即可完成对发条弹簧4预设的扭力调节。为更明显的提示用户对发条弹簧4的扭力调节方向调节，故可在盖板15上设置扭力调节方向的提示图案，以提示用户。
本实用新型的实施例2提供一种发条内置于上梁的发条卷取装置，如图4所示，与实施例1不同的是，
所述传动结构为带传动。
所述卷取盘6同轴连接有第一卷带盘17，所述支架2内安装第二卷带盘18，所述支架2内还安装有定滑轮20，所述第一卷带盘17和所述第二卷带盘18之间连接有皮带19，所述皮带19通过所述定滑轮20改变所述皮带19的方向。

皮带19传动的方式较为平稳，且无噪音，成本较低。
本实用新型的具体应用如下：卷帘的下端设置有配重块(该结构为现有技术，因此图中未示出)，用户下拉卷帘同时带动卷轴3转动，通过传动结构传 动带动发条弹簧4积蓄扭力。当用户停止拉动卷帘时，发条弹簧4的扭力与配重块的重力两者达到力平衡，可以使得卷帘停在任意位置。当出现发条弹簧4的扭力不足或者过大时，可通过操作调节柱塞7，调节发条弹簧4预设的扭力，以使发条弹簧4的扭力与配重块达到力平衡，可使得卷帘停在任意位置。
对于本领域技术人员而言，显然本实用新型不限于上述示范性实施例的细节，而且在不背离本实用新型的精神或基本特征的情况下，能够以其他的具体形式实现本实用新型。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的。本实用新型的范围由所附权利要求进行限定，而不是上述说明限定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本实用新型内。不应将权利要求中的任何附图标记视为限制所涉及的权利要求。
此外，应当理解，虽然本说明书按照实施方式加以描述，但并非每个实施方式仅包含一个独立的技术方案，说明书的这种叙述方式仅仅是为清楚起见，本领域技术人员应当将说明书作为一个整体，各实施例中的技术方案也可以经适当组合，形成本领域技术人员可以理解的其他实施方式。
