Abstract

本实用新型公开了一种手拉葫芦下钩总成，包括下钩架，所述下钩架的底部穿设有吊钩，所述吊钩的上端具有转轴，所述转轴的上端穿过下构架的底面伸入到下构架内且转轴上端侧壁上设有环槽，所述环槽内设有支撑圈，所述支撑圈与下构架的接触的外侧面上设有O型圈，所述支撑圈下方的转轴上固定安装有推力轴承。本实用新型下钩架总成可以360度位置任意转动。

Description

手拉葫芦下钩总成
技术领域
本实用新型涉及一种手拉葫芦下钩总成。 
背景技术
通常用的手拉葫芦下钩总成是由下吊钩、下钩梁、钢球、游轮、游轮轴及左右侧板组成，采用复合式机构。缺点是手拉葫芦起吊重物时，下钩总成不能灵活转动，无法实现360度的任意旋转而起吊重物。 
实用新型内容
本实用新型提供一种下钩架总成可以360度位置任意转动的手拉葫芦下钩总成。 
本实用新型解决技术问题提供如下方案： 
一种手拉葫芦下钩总成，包括下钩架，其特征在于：所述下钩架的底部穿设有吊钩，所述吊钩的上端具有转轴，所述转轴的上端穿过下构架的底面伸入到下构架内且转轴上端侧壁上设有环槽，所述环槽内设有支撑圈，所述支撑圈与下构架的接触的外侧面上设有O型圈，所述支撑圈下方的转轴上固定安装有推力轴承。 
所述推力轴承的下方与下钩架的底面之间设有垫圈，所述吊钩上设有卡索板。 
本实用新型的下吊钩轴颈部位装有平面轴承，以及下钩架片，用螺栓紧固为灵活性复合式下钩架总成,360度位置任意转动。 
附图说明
图1为本实用新型的结构示意图。 
具体实施方式
参见附图，一种手拉葫芦下钩总成，包括下钩架1，所述下钩架1的底部穿设有吊钩2，所述吊钩2的上端具有转轴3，所述转轴3的上端穿过下构架1的底面伸入到下构架1内且转轴上端侧壁上设有环槽4，所述环槽4内设有支撑圈5，所述支撑圈5与下构架1的接触的外侧面上设有O型圈6，所述支撑圈5下方的转轴上固定安装有推力轴承7，所述推力轴承7的下方与下钩架1的底面之间设有垫圈8，所述吊钩2上设有卡索板9。
