Abstract

本发明公开了一种防钻结构,包括外侧壁层、内侧壁层,在内侧壁层中设置多个钢球,钢球的上部伸入外侧壁层的小孔中,小孔的直径小于钢球直径。本发明结构合理,可以有效起到防钻、防盗作用。

Description

防钻结构
技术领域:
本发明涉及一种可有效防止被机械钻孔而造成失效的防钻结构。
背景技术:
现有的保险柜等装置,其装有锁的外壁由于结构等原因,易被钻头钻孔,使锁失去作用,从而造成内容物被盗。
发明内容:
本发明的目的在于提供一种结构合理,钻头无法钻透壁层,防盗效果好的防钻结构。
本发明的技术解决方案是:
一种防钻结构,包括外侧壁层、内侧壁层,其特征是:在内侧壁层中设置多个密集分布、且相互具有间隙的钢球,钢球的上部伸入外侧壁层的孔中,该孔的直径小于钢球直径。
多个钢球密集分布、且相互具有间隙。外侧壁层包括外层,外层内设置具有小孔的内层。
本发明结构合理,由于钢球的上部伸入外侧壁层的小孔中,而小孔的直径小于钢球直径,所以钻头钻孔时,要钻透壁层,必定要先钻过钢球体才有可能,而由于钢球的高硬度和球形形式,钻头要想钻过钢球体是很困难的,因此可以有效起到防钻、防盗作用。
附图说明:
下面结合附图和实施例对本发明作进一步说明。
附图是本发明一个实施例的结构示图。
具体实施方式:
一种防钻结构,包括外侧壁层、内侧壁层2,外侧壁层包括外层4,外层4内设置具有小孔5的内层3,在内侧壁层2中设置多个密集分布、且相互具有间隙的钢球1,钢球1的上部伸入小孔5中,小孔5的直径小于钢球直径。
外侧壁层也可以不设内层,而直接将小孔设置在外层上。
