Description

External thread cleaning tool

Technical Field

The invention relates to the field of cleaning tools, in particular to an external thread cleaning tool.

Background

The bolt is used under the environment that humidity, dust were beaten for a long time, can mix with impurity such as rust, dust, gravel, the butter of drier knot between the screw thread of bolt, can influence the meshing of bolt and nut screw thread because of the impurity between the screw thread when the bolt is dismantled and is reused, consequently need clear up the impurity between the screw thread. The common operation worker adopts tools such as a steel wire brush and a small blade to clean, but has the defects of incomplete impurity cleaning, low cleaning efficiency, easy scratching of the hand and the like, and when the cleaning between the threads does not completely lead to the secondary installation of the bolt, the installation of the bolt is influenced because of the impurities entering the gap between the bolt and the nut, and the bolt can not be detached again even because the threads of the bolt or the nut are damaged.

The Chinese patent publication No. CN204817268U discloses a cleaning barrel structure with an outer wall wrench square and an internal thread, but each cleaning barrel can only clean an external thread piece matched with the internal thread, and the application range is narrow; and when the internal thread of the cleaning barrel is damaged, the cleaning barrel needs to be discarded, so that the cost is wasted.

In order to solve the above problems, we have always sought an ideal technical solution.

As a further improvement of the technical scheme, the cleaning knife rest is detachably connected with the cleaning blade, so that the cleaning knife rest is convenient to replace after the cleaning blade is damaged, and the use cost is saved.

As a further improvement of the technical scheme, the cleaning blade is a saw blade, and impurities are cleaned by utilizing the friction force of saw teeth of the saw blade.

As a further improvement of the technical solution, the tensioning structure further comprises an elastic part, and the elastic part is located at the bottom of the tensioning structure. The elastic part can be an elastic rope section or a spring, and the cleaning piece is pressed tightly by the elastic force of the elastic part to prevent the cleaning piece from moving. When the elastic part is a spring, the diameter of the external thread part of the cleaned part is limited: the diameter of the outer thread part of the cleaned part is larger than that of the downward cleaning tool rest when the spring is in a natural extension state, and when the outer end of the spring contacts the tensioning through hole, the cleaning tool rest, the clamping rod and the base form a triangle-clamped inscribed circle diameter.

As a further improvement of the technical scheme, the elastic part is a spring, the flexible outer end part is a flexible rope, one end of the spring is fixed on the base, and the other end of the spring is connected with the flexible rope.

As a further improvement of the technical scheme, the tensioning structure is a rope with elasticity.

Compared with the prior art, the invention has outstanding substantive characteristics and remarkable progress, and particularly, the invention adjusts the length of the flexible outer end part which is tightly propped by the propping bolt so as to adjust the diameter of the external thread which can be cleaned. Furthermore, the triangular clamping structure can clamp the cleaned piece stably. Furthermore, the cleaned piece is cleaned in the rotating process, and the cleaning device is simple to operate and convenient to use. The clamping device has the advantages of simple structure, stable clamping, convenience in adjustment and wide application range.
