Description

一种保存长幅照片的收藏装具 技术领域
本发明属于文物保护设备技术领域,涉及一种照片收藏装具,具体涉及一种保存长幅照片的收藏装具。
背景技术
历史照片将某一瞬间定格在方寸之中,真实生动地记录了当时的社会事件、历史人物、城乡面貌、名胜古迹、民生百态等,比文字资料更加真实地记录、还原了历史。最常见的历史档案照片的片基层多为纸张,照片的显影材料则以银盐居多,更古老的是蛋白,这些材料的特殊性决定了它们比一般纸质文献更容易受到外界环境的影响而损坏,也决定了他们的保存与保护将更为特殊。
历史照片从形态上可分类为普通尺寸单幅照片、裱褙板单幅照片、长幅(巨幅)照片、照片册、相框等。长幅(巨幅)照片:长度在40厘米以上的照片。因幅面较大,照片在入藏时多呈卷筒状,有些配有筒状纸盒,更多的没有装具。相比普通尺寸照片,绝大多数纸质类的长幅照片因长期呈卷曲状存放,大多数照片难以打开,卷曲程度大且出现不同程度的折条甚至断裂。另外,有些长幅照片的则使用纸张、塑料封护、镜框装裱等保存方式。
现在我国国内照片保存材料生产方面不令人乐观,几乎无处去购买“无酸纸”或者“微碱性纸”。现在国内很多博物馆和档案馆用的较多的是“硫酸纸”由于这种纸张对于纤维含量和纯度没有要求,再加上在工艺中应用浓硫酸,人们不清楚后续工艺是否可以完全去除硫化物,这种纸张达不到保护照片和底片的要求。塑料封护、镜框等封护方式在长期的保存过程中照片影像层出现了泛黄、模糊,影像层与塑料薄膜及玻璃板之间发生了严重的粘黏现象,此外封护保护由于照片本身释放有害气体,加速老化。
发明内容
为了克服上述现有技术存在的缺陷,本发明的目的在于提供一种保存长幅 照片的收藏装具,该收藏装具结构设计合理,使用方便,能够持久、稳定的保护长幅历史照片。
本发明是通过以下技术方案来实现:
本发明公开的一种保存长幅照片的收藏装具,包括柜体,柜体内设置若干层用于放置长幅照片且可抽拉的拱形抽拉板;在拱形抽拉板的底部嵌设有磁性电镀板,在拱形抽拉板的表面设置有若干与磁性电镀板磁性配合的软磁条;使用时,待收藏的长幅照片置于拱形抽拉板上,由软磁条压在长幅照片边缘进行固定。
进一步优选地,软磁条压在长幅照片四周进行固定。
优选地,在每层拱形抽拉板上放置5~10张照片,每张照片的影像层表面覆盖有碳素隔卷纸,软磁条压在最上层的碳素隔卷纸边缘进行固定。
优选地,在拱形抽拉板的底部边缘嵌设有2~5cm宽的磁性电镀板。
优选地,在每层拱形抽拉板上设有抽拉孔。
进一步优选地,所述抽拉孔有两个,均布在拱形抽拉板的前壁上。
优选地,柜体前壁设有可拆卸的隔板。
进一步优选地,所述隔板由透明材料制成。
优选地,在柜体底部四周还设有滚轮。
与现有技术相比,本发明具有以下有益的技术效果:
本发明公开的保存长幅照片的收藏装具,在柜体内设置若干层可以抽拉的拱形抽拉板,拱形抽拉板的设置使得长幅照片能够充分被展平,不再发生反复性、记忆性卷曲。同时,在该拱形抽拉板的底部嵌设有磁性电镀板,在拱形抽拉板表面放置若干条软磁条,利用软磁条磁性电镀板配合形成的磁力吸附作用,固定长幅照片。该收藏装具结构设计合理,使用方便,能够持久、稳定的保护长幅历史照片。
进一步地,每层拱形抽拉板根据实际使用需求可以放置5~10张长幅照片, 但是照片和照片之间如果直接叠放,长期会导致影像层之间出现粘黏现象,因此,在每张照片的影像层表面覆盖有碳素隔卷纸,碳素隔卷纸会吸附收藏装具内的水分,降低收藏装具环境中的湿度,并且可以阻隔酸性气体、氧化性气体对照片影像层的危害,使得照片影像画面耐久性提高。
进一步地,在每层拱形抽拉板的前壁上设有抽拉孔,方便使用者抽拉拱形抽拉板,且节约空间。
进一步地,在柜体的前壁还设有隔板,能够有效防止灰尘等环境污染;更近一步地,隔板由透明材料制成,如玻璃、透明塑料等材料,配合标签等标记方便查找所需的照片。
进一步地,在柜体底部还设有滚轮,方便移动。
附图说明

图2为本发明公开的收藏装具的主视图;
图3为本发明公开的收藏装具夹装照片的局部结构放大图。
其中:1为柜体;2为拱形抽屉;3为软磁条;4为抽拉孔;5为碳素隔卷纸;6为磁性电镀板。
具体实施方式
下面结合附图对本发明做进一步详细描述:
参见图1和图2,本发明公开的保存长幅照片的收藏装具,包括柜体1,柜体1内设置若干层用于放置长幅照片且可抽拉的拱形抽拉板2;在拱形抽拉板2的底部嵌设有磁性电镀板6,在拱形抽拉板2的表面设置有若干与磁性电镀板6磁性配合的软磁条3;使用时,待收藏的长幅照片置于拱形抽拉板2上,由软磁条3压在长幅照片边缘进行固定。
优选地,软磁条3压在长幅照片的边缘四周,固定更加牢固、可靠。拱形抽拉板2底部边缘嵌设的磁性电镀板6的宽度为2~5cm。软磁条3与磁性电镀 板6形成磁力吸附,对照片整体固定。
优选地,在每层拱形抽拉板2上设有抽拉孔4,方便使用者抽拉拱形抽拉板2,且抽拉孔4有两个,设置在拱形抽拉板2的前壁上.
优选地,柜体1前壁设有可拆卸的隔板,能够有效防止灰尘等环境污染;更近一步地,隔板由透明材料制成,如玻璃、透明塑料等材料,配合标签等标记方便查找所需的照片。
在柜体1底部四周还设有滚轮,方便使用者移动柜体1。
参见图3,在每层拱形抽拉板2上能够放置5~10张照片,每张照片的影像层表面覆盖有碳素隔卷纸5,软磁条3压在最上层的碳素隔卷纸5边缘进行固定。
本发明的柜体1、拱形抽拉板2选用“四防”板材,“四防”板材指的是具有防火、防虫、防霉、防酸的材料,使得制成的装具为一种耐久型环保收藏装具。采用的碳素隔卷纸,碳素物理化学性能稳定,较小的碳素颗粒可以吸收光,有效防止光老化。碳素隔卷纸会吸附装具内的水分,降低装具环境中的湿度,并且可以阻隔酸性气体、氧化性气体对影像层的危害,是照片影像画面耐久性提高。
综上所述,本发明公开的保存长幅照片的收藏装具能够长期、有效的稳定保存长幅历史照片,对保护珍贵历史照片具有重大的意义。
