The utility model discloses a weight bearing structure of a hand squash, which includes a chain, one end of the chain is fixed to the hook with hanged articles, and the other end of the chain is fixedly connected with a limited bit ring. The hook includes a cover plate, a shell and a hook body. The cover plate is located on the upper part of the shell, and a chain hole is set in the middle of the cover plate. The cover plate and the folded edge are fixed connected through the bolt pair. The pin holes are arranged on the outer shell of the pin shaft, and the end chain ring of the chain is hung on the pin shaft through the chain hole, and the bottom of the shell is provided with a through hole, and the bottom is arranged on the bottom of the shell. The upper end of the hook is set with external thread, the outer mesh of the outer thread has a nut one, the outer sleeve of the upper end of the outer shell of the outer shell is set with a spring two, the top of the spring two top and the nut are set with a roof, the outer hook of the outer shell is set with a finite bit ring, and the lower part of the hook is set with a self locking device. The utility model adopts the load bearing structure of the hand hoist, which can solve the problem that the hoisting hook is sloshing seriously in the process of lifting, and the limit pull ring is easily deformed and the limit effect is poor.

一种手扳葫芦承重结构
本技术涉及手扳葫芦提升装置
,尤其是涉及一种手扳葫芦承重结构。
技术介绍
手扳葫芦是一款使用简单,携带方便的手动起重工具,手扳葫芦可以进行提升、牵引、下降、校准等作用,广泛的应用于造船、电力、运输、建筑、矿山等行业。手扳葫芦的承重链条一端连接吊钩,另一端连接限位拉环。手扳葫芦在提升过程中,通常会出现吊钩晃动的情况,吊钩的晃动会增加承重链条的负担,从而影响链条的使用寿命。另外,手扳葫芦常用的限位拉环单独的圆形的金属环,金属环容易变形、稳定性差,并且金属环容易卡入链轮两侧的挡板之间,限位效果差。
技术实现思路
本技术的目的是提供一种手扳葫芦承重结构,解决吊钩在起吊过程中晃动严重,限位拉环易变形、限位效果差的问题。为实现上述目的,本技术提供了一种手扳葫芦承重结构,包括链条,所述链条的一端固定连接有吊挂物品的吊钩,所述链条的另一端固定连接有限位拉环;所述吊钩包括盖板、外壳和钩体,所述盖板位于所述外壳的上部,所述盖板的中部设置有链孔一,所述外壳的顶端设置有折边,所述盖板与所述折边通过螺栓副固定连接,所述外壳上设置有可使销轴横穿所述外壳的销孔,所述销轴一端的端头的直径大于所述销孔的直径,所述销轴的另一端设置有定位孔,所述定位孔上穿设有可防止所述销轴滑脱的插销,所述插销与所述外壳的外壁之间的所述销轴上套设有垫片,所述链条一端的末端链环穿过所述链孔一挂套在所述销轴上,所述外壳的底部设置有可使钩体插入所述外壳内部空腔的通孔一,所述钩体的上端设置有外螺纹,所述外螺纹的外部啮合有螺母一,位于所述外壳内部的所述钩体的外部套设有弹簧二,所述弹簧二的顶端与所述螺母 ...
