[0002] The magnetic thickness gauge for auto repair is an auto repair tool used to measure the thickness of the car paint surface during auto repair. The commonly used magnetic thickness gauge for auto repair on the market is a magnetic measuring pen, which can quickly check without leaving any traces. The pen tip with magnetic attraction touches the paint surface, and the pen is pulled out to see how long the magnetic tip of the pen extends when it is magnetically attracted to the car body. The shorter the length, the weaker the detected magnetism, and the longer the length, the stronger the detected magnetism. After the magnetism disappears, the magnetic tip of the pen rebounds and resets. However, the existing measuring pen rebounds too quickly when in use, resulting in the measurement results that cannot be seen clearly in a short time, and it is not convenient to use. Therefore, a simple and convenient magnetic thickness gauge is needed to meet the demand. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-6 As shown, the utility model provides a technical solution: a magnetic thickness gauge for auto repair, comprising a sleeve 1, a magnetic measuring rod 2, a spring 3, an upper plug 4 and a lower plug 5. The outer surface of the sleeve 1 is provided with a scale line 101 for measuring magnetism along the length direction, and the scale line 101 indicates the thickness of the paint coating. The outer surface of the sleeve 1 is also provided with a guide slot 102 penetrating the tube body along the length direction;

[0020] The sleeve 1 is slidably mounted with a slider 6 through the guide slot 102. The slider 6 includes a sliding member 601 slidably arranged on the guide slot 102 and a pointer 602 connected to the sliding member 601 and movably connected to the outside of the sleeve 1. The pointer 602 is arc-shaped, and the arc angle of the pointer 602 is greater than 180° and is not easy to be separated from the guide slot 102. The two ends of the pointer 602 correspond to the two sides of the scale line 101, which is convenient for reading.

[0021] An upper plug 4 is installed at the upper end of the sleeve 1, and a lower plug 5 is installed at the lower end of the sleeve 1. The upper plug 4 and the lower plug 5 are respectively threadedly connected to the two ends of the sleeve 1. A channel is arranged along the axial direction of the lower plug 5. A magnetic head 201 is arranged at the lower end of the magnetic measuring rod 2. A hinged protective cover 7 is arranged on the upper plug 4. The protective cover 7 is a semi-tube type. The protective cover 7 is opened by turning up along the hinged end. The protective cover 7 is not easy to be lost when opened. The protective cover 7 is turned down along the hinged end to cover the guide slot 102 and the magnetic head 201, so as to protect the guide slot 102 and the magnetic head 201.

[0022] The magnetic measuring rod 2 is inserted into the sleeve 1, and one end of the magnetic head 201 of the magnetic measuring rod 2 passes through the lower plug 5 and extends to the outside. An end cap 202 is arranged at the upper end of the magnetic measuring rod 2, and a shift block 203 is arranged on one side of the end cap 202. The shift block 203 passes through the guide slide groove 102 and extends to the outside of the sleeve 1. The shift block 203 is located above the slider 6 and is slidably arranged with the guide slide groove 102. The spring 3 is sleeved on the magnetic measuring rod 2, and the two ends of the spring 3 are respectively pressed between the lower plug 5 and the end cap 202. The spring 3 is movably connected in the sleeve 1 along the axial direction with the magnetic measuring rod 2;

[0023] When in use, flip open the protective cover 7, the end of the magnetic head 201 is exposed to the outside, the outer end of the magnetic head 201 is contacted with the vehicle body, and the sleeve 1 is held and pulled outward. There is magnetic attraction between the vehicle body and the magnetic head 201. When the sleeve 1 is pulled, the magnetic measuring rod 2 will extend out of the sleeve 1, and the spring 3 is compressed. When the magnetic measuring rod 2 is extended, its shift block 203 drives the slider 6 on the guide slide groove 102 to slide in the same direction and the same length as the extension of the magnetic measuring rod 2. When the magnetic attraction is not enough to overcome the elastic force of the spring 3, the magnetic measuring rod 2 rebounds under the action of the spring 3, and the slider 6 still stays in the current position. The magnetic thickness can be judged according to the position of the scale line 101 pointed by the pointer 602. When the magnetism is weak, the length of the magnetic measuring rod 2 extending out of the sleeve 1 is short. When the magnetism is strong, the length of the magnetic measuring rod 2 extending out of the sleeve 1 is long. When continuing to detect the magnetism of the next position, manually slide the slider 6 to the initial position close to the shift block 203.
