Embodiment Construction

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. And the features in the embodiments can be combined with each other.

[0022] Such as Figure 1 to Figure 3 As shown, a bolt anti-corrosion paint removal device provided by the embodiment of the present invention includes a body 1, the body 1 is provided with a hole 5 for the screw to penetrate, the body 1 is provided with a cutter 2, and one end of the cutter 2 A knife point 21 protruding into the hole 5 from the side of the hole 5 is provided. The shape of the knife point 21 is a triangle or a trapezoid that fits with the thread. The knife point 21 is preferably triangular, and the tip angle of the knife point is 45 degrees. . When the material of the knife tip 21 is selected, it should be taken into account that the scr...

Abstract

The invention discloses a clearing device for bolt anti-corrosion oil paint. The clearing device comprises a body (1). A hole (5) capable of allowing a threaded rod to penetrate is formed in the body(1), and a tool (2) is arranged on the body (1); and a tool nose (21) stretching into the hole (5) from the side portion of the hole (5) is arranged at one end of the tool (2), and the tool nose (21)is in a triangle or trapezoid shape matched with a thread. During use, the to-be-cleared threaded rod is sleeved with the hole, thus a screw thread of the threaded rod is clamped by the tool nose of the tool, an outer clamp cover is manually locked, the body is rotated through a ratchet wrench, the tool nose longitudinally moves along with a threaded track, and the oil paint in a threaded groove can be cleared along the tool accordingly. According to the clearing device for the bolt anti-corrosion oil paint, the problem that the threaded rod paint is difficult to clear can be solved, the thread can be prevented from being damaged during screw thread oil paint clearing, the occurrence probability of the device or pipeline connector thread damage situation is decreased, and the maintenance work load is reduced.

Description

technical field [0001] The invention relates to a device suitable for removing anticorrosion paint from bolts. Background technique [0002] In the prior art, when removing the anti-corrosion paint on the bolts, a paint remover or a flat-head screwdriver is generally used to knock the paint. More maintenance workload, lower efficiency. [0003] The purpose of the foregoing discussion is to introduce the reader to various aspects of the technology that may be related to various aspects of the present invention that will be described and / or claimed below. It is believed that the discussion will help provide background information for the reader to facilitate a better With the various aspects of the present invention in mind, it is therefore to be understood that these discussions are to be read in this light, and not as admissions of prior art. Contents of the invention [0004] The purpose of the present invention is to avoid the deficiencies in the prior art and provide ...
