Description

Technical Field

[0001] This utility model relates to the field of anti-slip pad technology, and in particular to an adjustable anti-slip pad for double-headed bolts. Background Technology

[0002] A double-ended stud bolt is a bolt with threads at both ends. The threads at both ends may have the same shape and different dimensions, and it can be used to connect or fix two objects in various applications. One end of the double-ended stud bolt is typically used to fix the connected object, while the other end may be connected to another component or fastener. The characteristic of this type of bolt is that it has threads at both ends, allowing it to be directly screwed into two nuts, fasteners, or equipment. It is widely used in machinery, construction, automotive, and other fields, and is suitable for situations requiring fixation in two directions. To increase the stability of the bolted connection and prevent loosening, an anti-slip washer is placed between the nut and the connecting part. Anti-slip washers are usually made of metallic or non-metallic materials, providing additional friction to prevent the nut from loosening due to vibration, external force, or long-term use. However, the inner diameter of existing anti-slip washers is not easily adjustable according to the outer diameter of the bolt, limiting their applicability. Therefore, an adjustable anti-slip washer for double-ended stud bolts is needed. Utility Model Content
