[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0019] Please refer to Figures 1-4 , the present utility model discloses a protection device for a power monitoring instrument, including a protective housing 10. A through hole 20 is provided in the middle of the rear end of the protective housing 10. Two power monitoring instrument fastening components 30 are provided inside the protective housing 10. A pair of sliding grooves 40 are provided on the front surface of the protective housing 10. A protective sliding cover 50 that is simultaneously slidably connected up and down with the two sliding grooves 40 is provided on the front surface of the protective housing 10.

[0020] Specifically, the protective sliding cover 50 includes a transparent cover plate 51 that is simultaneously slidably connected up and down with the two sliding grooves 40. A blocking strip 52 is integrally connected to the lower part of the back surface of the transparent cover plate 51. A push rod 53 is slidably inserted into the front surface of the transparent cover plate 51. A receiving circular groove 54 is provided in the lower part of the back surface of the transparent cover plate 51. A jack 60 that matches the push rod 53 is provided above the front surface of the protective housing 10. The outer diameter of the rear end of the push rod 53 is larger than the outer diameter of the front end of the push rod 53.

[0021] In this implementation scheme, the setting of the protective sliding cover 50 can protect the display screen of the power monitoring instrument and prevent accidental touching of the buttons, which can effectively improve the use safety of the power monitoring instrument and will not interfere with the use and observation of the power monitoring instrument. The opening steps are as follows: slide the transparent cover plate 51 upward until it cannot be slid upward further. At this time, the blocking strip 52 fits against the upper inner wall of the protective housing 10. Push the push rod 53 backward. At this time, the push rod 53 moves backward and is inserted into the jack 60, which can lock the position of the transparent cover plate 51 at this time. At this time, the buttons of the power monitoring instrument can be operated.

[0022] Specifically, the power monitoring instrument fastening component 30 includes a long strip 31 fixedly connected to the side wall of the protective housing 10. Two inclined guide posts 32 are integrally connected to the back surface of the long strip 31. A pressing strip 33 is slidably connected between the two guide posts 32. A spring 34 is fixedly connected between the pressing strip 33 and the long strip 31. A stud 35 is threadedly connected to the front end of the long strip 31. A push plate 36 is fixedly connected to the rear end of the stud 35. A knob 70 is fixedly connected to the front end of the stud 35. The push plate 36 is a circular structure. The knob 70 is received in the protective housing 10.

[0023] In this implementation, when the forward rotation knob 70 is turned, the stud 35 rotates and moves backward. At this time, the pressing strip 33 is squeezed by the pushing piece 36 and moves backward along the inclined guide post 32, and tightly presses against the front of the power monitoring instrument, so as to realize the fixed installation of the power monitoring instrument. Similarly, when disassembling, only need to reverse the knob 70. Under the pulling of the spring 34, at this time, the pressing strip 33 tilts and moves forward, and at this time, the power monitoring instrument loses the extrusion and can be pulled out and removed.

[0024] Specifically, a glue filling groove 80 is opened at the rear end of the protective housing 10, and a plurality of fine grooves 90 communicating with the glue filling groove 80 are opened on the back of the protective housing 10.

[0025] In this implementation, glue can be applied and fixedly connected to the outer shell of the power equipment, and the connection is firm and stable. At this time, the power monitoring instrument fastening assembly 30 can be used to fix the power monitoring instrument.

[0026] The working principle and usage process of the present utility model:

[0027] There are two installation methods: The first installation method is to put the protective housing 10 on the power monitoring instrument. At this time, the power monitoring instrument is inserted into the through hole 20, and then the protective housing 10 and the power monitoring instrument are embedded in the outer shell of the power equipment together. Finally, the power monitoring instrument is fixed on the outer shell of the power equipment through screws or other installation structures. At this time, the protective housing 10 is clamped between the outer shell of the power equipment and the front panel of the power monitoring instrument and is in a locked state; when it is not necessary to directly fixedly connect the power monitoring instrument to the outer shell of the power equipment, at this time, the protective housing 10 can be fixed to the outer shell of the power equipment through glue, and then the power monitoring instrument is inserted. When the forward rotation knob 70 is turned, the stud 35 rotates and moves backward. At this time, the pressing strip 33 is squeezed by the pushing piece 36 and moves backward along the inclined guide post 32, and tightly presses against the front of the power monitoring instrument, so as to realize the fixed installation of the power monitoring instrument. The two installation methods can meet different actual needs.
