Quickly-adjustable nut

Abstract

The invention relates to a quickly-adjustable nut. The quickly-adjustable nut is characterized by being provided with an inner sleeve. Circular holes are circumferentially reserved on the right of the inner sleeve and distributed on a helical line of the inner sleeve, steel balls are mounted in the circular holes, an annular groove is reserved on the left portion of the inner sleeve, an axial groove is reserved in the annular groove, a compression spring is arranged in the annular groove, an inner barb is arranged at one end of the compression spring, and an outer barb is arranged at the other end of the compression spring. A right movable retaining ring is arranged on the right side of the compression spring, a left movable retaining ring is arranged on the left side of the compression spring, and both the right movable retaining ring and the left movable retaining ring are arranged in the annular groove. An outer sleeve is sleeved outside the inner sleeve, a circular step hole is reserved in the inner sleeve, another axial groove is reserved on the left portion of the inner wall of the outer sleeve, an annular channel groove is arranged on the left side of the axial groove, a snap spring is mounted in the channel groove, the inner barb at one end of the compression spring is disposed in the axial groove of the inner sleeve, the outer barb at the other end of compression spring is disposed in the axial groove of the outer wall of the outer sleeve, and a circular hole in the middle of the outer sleeve is in movable fit with the inner sleeve. The quickly-adjustable nut is reasonable in design, simple in structure, easy to manufacture, convenient to use and operate, timesaving and laborsaving. Besides, axial moving of the nut can be realized by quick adjustment, and work efficiency of operators is improved during use.

Description

technical field [0001] The invention relates to a nut, in particular to a fast adjustable nut. Background technique [0002] At present, the position movement of the nut in the traditional threaded connection structure is realized by the relative rotation of the inner thread of the nut and the outer thread of the screw. The work efficiency is low and the operation is troublesome. This problem is more obvious especially in long threads. For example, when the hardware tool hawk nose pliers (European pipe wrench) clamps pipes with large diameter changes, the nut needs to be tightened and loosened continuously to adjust the opening of the pliers, which is time-consuming and laborious. In order to change the threaded connection structure in which the axial movement of the nut can only be realized by the relative rotation of the nut and the screw rod, a new type of nut that can realize the fast movement of the nut without the relative rotation of the nut and the screw rod is desig...

Problems solved by technology

[0002] At present, the position movement of the nut in the traditional threaded connection structure is realized by the relative rotation of the inner thread of the nut and the outer thread of the screw. The work efficiency is low and the operation is troublesome. This problem is more obvious especially in long threads.

For example, when the hardware tool olecranon pliers (European pipe wrench) clamps pipes with large diameter changes, the nut needs to be tightened and loosened continuously to adjust the opening of the pliers, which is time-consuming and laborious.

In order to change the threaded connection structure in which the axial movement of the nut can only be realized by the relative rotation of the nut and the screw rod, a new type of nut that can realize the fast movement of the nut without the relative rotation of the nut and the screw rod is designed. It has the function of relative rotation and can solve the original problem The problem of time-consuming and labor-intensive connection between nut and screw
