A device for detecting the corrosion status of in-use bolts

Abstract

The invention discloses a detection device for the corrosion status of bolts in use, which includes a protective shell, a moving block, a moving plate, a screw rod, a detection device box and a winding column, and a detection device box is arranged inside the protective shell. Both sides of the box surface of the detection device are rotatably connected with a rotating disk, and one side of the two rotating disks is connected with a drive motor 3, and the surfaces of the two rotating disks are fixedly connected with one end of the connecting rod. The other ends of the connecting rods are fixedly connected with a connecting block, a vibrating tube is arranged between the two rotating discs, the bottom end of the vibrating tube is fixedly connected with a return spring 2, and the bottom end of the resetting spring 2 is fixedly connected to the support plate On the surface, the driving motor 3 can be driven to rotate the rotating disk, and the connecting rod and the connecting block on the surface of the rotating disk can be rotated together by rotating the rotating disk.

Description

technical field [0001] The invention relates to the technical field of corrosion condition detection devices, in particular to a corrosion condition detection device for in-use bolts. Background technique [0002] Bolt has a lot of call, and everyone call may be different, and someone is into screw, and someone is into bolt nail, and someone is into fastening member, and someone is into securing member. Although there are so many names, the meaning is the same, they are all bolts. A bolt is a general term for a fastener. Bolt is the physical and mathematical principle of using the oblique circular rotation and friction of the object to tighten the device parts step by step. [0003] Bolt, be can't do without when neutralizing in the middle of commercial production manufacture at daily life, and bolt is also referred to as the rice of industry. The utilization of visible bolt is extensively. The operation strategies of bolt has: electronic product, engineering goods, digi...

AI Technical Summary

Problems solved by technology

[0005] During the use of bolts, because the bolts are exposed to the outside world for a long time and oxidized for a long time, the bolts are easy to rust and affect the use of the bolts. Therefore, it is necessary to use a detection device to detect the rust of the bolts. Now for the current market The corrosion condition detection device of the present invention asks the following questions;

[0006] 1. In the process of bolt corrosion detection, generally the detection head is inserted into the bottom of the bolt, and the bolt corrosion state is detected through the detection head. In this process, it is easy to make the dust and rust on the surface of the bolt fall into the detection If the inside of the detection head is not cleaned in time, the use effect of the detection head will be affected, resulting in inaccurate detection of rust conditions;

[0007] 2. At present, most of the rust detection devices on the market are generally exposed to the outside world, so it is easier to collide with external things. Because the internal structure of the detection device is more precise, when a collision occurs, it is easier to cause damage to the detection device and affect the quality of the detection device. Normal use;

[0008] 3. During the use of the corrosion device, the connecting wire needs to be pulled out to a certain position according to the actual position of the bolt, so that the position of the detection head can be in contact with the bolt, and the connecting wire needs to be closed later. At present, the connecting wire is generally manually connected. Closing, this way is a waste of time and energy
