Abstract

一种钟表表轴防水密封套,由内套和外套组成,其中内套套装在外套内,内、外套间为间隙配合,内套的外圆面为粗糙表面,内套和外套均用人造宝石材料制成。该实用新型套装在钟表上发条的拨针表轴上,它不仅不影响钟表拨针上发条,而且防酸、碱腐蚀性强,耐高温、摩擦损耗小,不易变形,密封防水效果佳,使用寿命长。

Description

钟表表轴防水密封套
本实用新型涉及一种密封装置,尤其是钟表表轴防水密封套。
目前,在钟表表轴(即钟表的上条拨针柄轴)上采用的密封装置是橡胶圈。由于橡胶圈耐高温和防腐蚀性能不太高,很容易因老化变形而失去弹性。长期使用会失去密封防水作用,因此,橡胶圈作密封圈使用寿命较短。
本实用新型的目的是提供一种钟表表轴防水密封套,在保证钟表拨针能自如上条的基础上,具有较强的密封防水性能,并且使用寿命较长。
本实用新型的目的是这样实现的:用人造宝石制作一种双套层钟表表轴防水密封套,它套装在拨针表轴上,其结构要点是:内套套装在外套内,内、外套间为间隙配合,内套的外圆面为粗糙表面,内套和外套均用人造宝石材料制得。
将本实用新型套装在钟表拨针柄轴上,由于内套和外套间是间隙配合,因而不影响钟表拨针上发条。把内套外圆面制作成粗糙表面,可以保证有较好的密封防水效果。本实用新型采用人造宝石材料,具有较强的防酸、碱腐蚀性能和耐高温特性,摩擦损耗小,不易变形。
采用上述方案,结构简单,使用方便,防水效果好,使用寿命长。
下面结合附图及实施例对本实用新型进一步说明。
图1是本实用新型套装在钟表的拨针表轴上的情况。
由图1可知:本实用新型套装在拨针表轴1上,它由内套2和外套3组成,其中内套2套装在外套3内,内、外套间为间隙配合,内套2的外圆面为粗糙表面,内套2和外套3均用人造宝石材料制得。
