Description

Technical Field

[0001] The utility model relates to the technical field of metal fasteners, in particular to a metal fastener which is easy to rotate. Background Art

[0002] Metal fasteners are widely used in mechanical engineering, construction engineering, automobile manufacturing, aerospace and other fields. Their main function is to fix different parts together during assembly to form a stable structure. These fasteners are usually made of metal materials such as steel, stainless steel, aluminum, etc., with high strength, corrosion resistance and wear resistance, ensuring the firmness and durability of the connection. Common metal fasteners include bolts, nuts, screws, bolts, etc. They connect parts together by rotation or insertion, forming the basis of mechanical structures. Threaded connection is the most common connection method, which achieves a firm connection through the interlocking of threads. In addition, there are other connection methods such as welding and riveting.

[0003] At present, metal fasteners are often used to connect two pipes with different diameters. The two pipes are connected by metal fasteners, but the connection method of metal fasteners is mostly fixed by screws. In industrial facilities, pipeline systems often need to transport liquids or gases, and are affected by factors such as equipment operation and fluid pressure changes, causing vibration and impact on pipelines and connectors. The threaded connection of the screw is easy to loosen or even fall off, resulting in failure of the pipeline connection. Therefore, it is necessary to redesign a metal fastener that is easy to rotate to address the above problem. Utility Model Content

[0020] By inserting the pin 10 into the slide groove 7, the position of the screw 5 can be limited, so as to prevent the screw 5 from loosening and causing failure of the pipeline connection. At the same time, the inner wall of the slide groove 7 is annular, so no matter which direction the screw 5 is rotated to, it can be inserted into the slide groove 7, which improves the flexibility and convenience when rotating the screw 5.

[0021] Reference Figure 1 and Figure 2 The inner and outer walls of the upper clamp 1 and the lower clamp 2 are both annular, and the inner walls of the upper clamp 1 and the lower clamp 2 are both provided with rubber pads 3.

[0022] When the screw 5 is rotated to the inside of the lower clamping member 2 , a part of the screw 5 is clamped in the fixing groove 8 , thereby further limiting the position of the screw 5 .

[0023] In the utility model, the specific function of the device is: when using the device, the upper clamp 1 and the lower clamp 2 are clamped on the outer wall of the pipeline, and then the screw 5 is rotated to make the screw 5 threaded to the inside of the lower side plate 4, so as to fix the upper clamp 1 and the lower clamp 2, and at the same time achieve the purpose of fastening the two groups of pipelines. In this process, the slide plate 9 is pulled outward to drive the pin 10 to slide outward. At this time, the spring 11 is in a stretched state, and then the hand is released. Under the action of the elastic recovery force of the spring 11 itself, the pin 10 is driven to slide into the inside of the slide groove 7 and resist against the inner wall of the slide groove 7, so as to achieve the fixed limit of the position of the slide groove 7, thereby avoiding the loosening of the connection of the screw 5 and ensuring the effectiveness of the connection between the pipelines.
