An easy-to-use hardware universal ball head

Abstract

The invention discloses a hardware universal bulb convenient to use. The hardware universal bulb comprises a hardware universal bulb body, a hardware screw, a hardware nut and a connecting rod; a mounting rotary groove and a threaded connecting groove are formed in the middle of the hardware nut, the hardware screw is cooperatively connected into the threaded connecting groove through a thread, and an oil cavity is formed in the portion, below a hardware vortex sheet of the bulb, inside an arc rubber block in an arc retractable groove; the arc rubber block fits the upper surface of the hardware universal bulb body, oil in the oil cavity can fall off from oil holes under the squeezing and rotating effects of the hardware universal bulb body, the effect of lubricating the hardware universalbulb body is achieved, the wear among the devices is reduced, the service life of the bulb is prolonged, a retractable clamping block can be retracted in a retractable clamping groove by rotating a rotary rod, and the hardware universal bulb body is convenient to dismantle directly and convenient to use; the joint of screw caps is easily broken, when the second screw cap is broken, the first screwcap is conveniently utilized for controlling the hardware screw, and the hardware screw is not easily stuck in the threaded connecting groove.

Description

technical field [0001] The invention relates to the technical field of hardware, in particular to an easy-to-use hardware universal ball head. Background technique [0002] The metal ball head is used to transfer the connecting parts between two structures. It can be used as a turning point, and can also be used to fix or maintain the lubricity of the rotation between the structures. The metal ball head is widely used in many fields. In practice It is very common in life, but it still has the following disadvantages in actual use: [0003] 1. The existing hardware ball head has poor lubricity, which is prone to serious wear and tear during use, reducing its service life; [0004] 2. The existing hardware ball head is inconvenient to disassemble and fix, and there is a certain inconvenience in use; [0005] 3. Some metal ball heads are lubricated by lubricating oil, but at the same time, the surface of the metal ball head is easy to adhere to dust, and the use environment i...
