On the belt winding roller, One end of the lanyard is fixed, the lanyard can be wound on the said winding roller and the other end of the lanyard protrudes upwards from the said belt accommodating chamber, and the other end of the lanyard is fixed with As for the hook, the base is provided with a positioning mechanism for positioning the lanyard.

In some embodiments, the lanyard is 180cm-200cm long.

In some embodiments, the positioning mechanism includes a positioning piece that is rotatably connected to the lanyard seat through a rotating shaft, and the locating piece has a protrusion for conflicting with the lanyard, There is also a button on the locating piece for pressing to make it rotate around the axis of rotation, and a button is arranged between the locating piece and the strap seat so that the strap is tightly clamped between the base and the strap seat. The elastic part of the positioning part between the above-mentioned protrusions.

In some embodiments, an elastic member of the tape winding roller is arranged between the tape winding roller and the strap holder so that the strap retracts into the tape receiving cavity.

In some embodiments, the multimeter protective cover is made of plastic or rubber.

In some embodiments, the base is further provided with a gauge groove for accommodating a gauge gauge of a multimeter.

Due to the application of the above-mentioned technical scheme, the utility model has the following advantages compared with the prior art: the multimeter is accommodated in the meter storage space of the multimeter protective cover, thereby the hook is hung on the door of the electric cabinet or the electric box, and by adjusting the strap The length of the multimeter is adjusted to a suitable height, and the tester has a stick in one hand, and it is easy to read the data, which also improves the safety of the measuring personnel.

Detailed ways

The utility model will be further described below in conjunction with the embodiment shown in the accompanying drawings.

As shown in accompanying drawings 1-3, a kind of multimeter protective case comprises a surrounding edge 2, a base 1 connected with the surrounding edge 2, and a meter storage space capable of accommodating a multimeter is formed between the surrounding edge 2 and the inner surface of the base 1, The surrounding edge 2 has a hook edge protruding toward the watch storage space, and the hook edge helps to hook the multimeter in the watch storage space.

The outer surface of the base 1 is fixed with a lanyard seat 3 with a receiving cavity, and a belt winding roller 4 is rotatably connected in the belt accommodating cavity, and an end of a hanging belt 5 is fixed on the winding roller 4, and the hanging belt 5 can be wound around On the belt winding roller 4 and its other end protrudes upwards from the belt accommodation cavity, the other end of the hanging belt 5 is fixed with a hook 6, and the base 1 is provided with a positioning mechanism that makes the hanging belt 5 positioned.

Hanging belt 5 long 180cm-200cm. After the hook is hooked on the electric cabinet or electric box door, the surveyor can adjust the length of the hanging strap 5 as required to meet the needs of the work.

In order to realize the positioning of the lanyard 5 and the base 1, there are many structures of the positioning mechanism. In this embodiment, the locating mechanism includes a locating piece 7 connected to the lanyard seat 3 through a rotating shaft 9, and the locating piece 7 There is a protrusion 71 for conflicting with the lanyard 5, and a button 72 for pressing to make it rotate around the rotation axis 9 is also provided on the positioning member 7. A gap is arranged between the locating member 7 and the lanyard seat 3 so that the lanyard 5 The elastic part 8 of the positioning part is tightly clamped between the base 1 and the protrusion 71 . In addition, the positioning mechanism can also use the structure of rotating the eccentric to position the strap 5 relative to the base 1 .

An elastic member of the tape winding roller is arranged between the tape winding roller 4 and the tape hanging seat 3 so that the tape winding 5 tends to retract into the tape accommodation cavity. After the positioning mechanism is unlocked, under the action of the elastic member of the winding roller, the hanging belt 5 is automatically received into the belt accommodation cavity of the hanging belt seat 3 .

When in use, the positioning mechanism can be unlocked, that is, the button 72 can be pressed against the action of the elastic part 8 of the positioning part, and the length of the lanyard 5 can be adjusted, pulled out to a suitable length, and the button 72 is released, and the button 72 is positioned on the positioning part. Reset under the effect of elastic part 8, positioning mechanism locks, and hook 6 is hooked to the top of door, if the length of button 72 is not suitable, positioning mechanism can be unlocked again, and the length of adjustment belt hanging strap 5 is to suitable position again. The measurement can be carried out. After the measurement, the positioning mechanism is unlocked, and under the action of the elastic part of the winding roller, the lanyard 5 is stored in the belt accommodation cavity. It has a wide range of applications, regardless of the material of the door of the electric cabinet or electric box, it can be applied.
