Description

Technical Field

[0001] This utility model relates to the field of U-bolt auxiliary structure technology, and more specifically, to a U-bolt quick mold changing and positioning structure. Background Technology

[0002] U-bolts, also known as saddle bolts, are non-standard parts named for their U-shaped shape. They have threads at both ends that can be used with nuts. They are mainly used to fix tubular objects such as water pipes or sheet objects such as leaf springs in automobiles. Because the way they fix objects is like a person riding a horse, they are called saddle bolts.

[0003] When using U-bolts, it is often necessary to first insert the fittings into the holes and then fix them with locking devices. However, since the surface of the U-bolt does not have a mold-changing positioning structure, the hole-setting process is slow and the production efficiency is low during production. Therefore, we have proposed a U-bolt quick mold-changing positioning structure to solve the above problems. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a quick mold-changing positioning structure for U-bolts. The U-bolt body has a positioning component installed inside. During assembly, the U-bolt body is held, and the carrier plate is rotated relative to the limiting shaft frame according to the shape of the auxiliary structure of the assembly until the positioning post or block aligns with the auxiliary structure of the assembly. After alignment, the U-bolt body is pressed down longitudinally, and the threaded end of the U-bolt body aligns with the assembly. The guide rod slides relative to the guide cylinder, and the return spring undergoes elastic deformation within its elastic limit, ensuring smooth alignment and excellent auxiliary guiding performance, thus improving assembly efficiency. An assembly base is fixedly connected to the end of the guide cylinder. The surface of the assembly base has a positioning groove, and a limiting post is fixedly connected inside the assembly groove of the U-bolt body. Depending on the needs of use, the assembly base and the U-bolt body can be held and aligned. The positioning groove of the assembly base and the limiting post are fixedly connected, ensuring stable assembly.
