The utility model provides a new type of anti rust screw screw. The upper end of the nail cap and the side wall are respectively provided with two oil injection holes, and the two oil passages corresponding to the two oil injection holes are vertically connected in the nail cap, with a plurality of oil outlet channels in the screw, and the oil outlet channels are connected to the oil inlet channel, and the outflow outlet of the oil outlet channel is provided with several oil outlets. The oil outlet is located at the edge of the thread, one end of the oil outlet is connected with the oil outlet, the other end of the oil outlet passes through the screw and connects with the outside; the upper part of the oil hole is fitted with an oil plug, the cap and the screw are set with sealant sleeve, the sealant cover is fixed on the lower surface of the nail cap, and the sealing rubber sleeve is equipped with liquid glue. The inner of the screw is provided with a channel of lubricating oil, which can effectively prevent its rust, and a sealant cover is fixed under the cap. When the screw is tightened with the help of external force, the sealing glue sleeve is extruded to its rupture, the liquid glue is outflowing in the period, and the sealing and fastening are used.
【技术实现步骤摘要】
一种新型防锈螺纹钉
本技术属于机械工装领域,尤其是涉及一种新型防锈螺纹钉。
技术介绍
螺纹钉常见于机械、电器及建筑物等,其主要功能是接合二个物体,或者是固定一物体的位置,是一种非常常用的连接、紧固件。当螺钉旋入物体内长时间使用后,容易受到空气的侵蚀,就会有生锈的现象发生,容易损坏,使得机器在维维修和检修的时候,螺钉不易拆卸,对工作会造成很多不便。
技术实现思路
有鉴于此,本技术旨在提出一种新型防锈螺纹钉,结构简单,能够有效防止生锈,延长螺钉的使用寿命,同时具有加固功能。为达到上述目的,本技术的技术方案是这样实现的:一种新型防锈螺纹钉,包括螺钉帽、螺杆和钉尖,钉帽和钉尖分别固定连接在螺杆的两端,螺杆外表面设有螺纹,所述钉帽的中心位置设有凹槽以及设在圆形凹槽内的一字形或十字形拧紧槽,钉帽的上端和侧壁分别设有两注油孔,与两注油孔对应的两进油道在钉帽内部相互垂直连通,螺杆内设有多个出油通道,出油通道与进油道相通,出油通道上向外发射的设有若干出油口,出油口设于螺纹的边缘处,出油口的一端与出油通道相通,出油口的另一端穿透螺杆与外界相通;所述注油孔内对应设有油塞,密封胶套设于钉帽的 ...
