[0018] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example 1

[0020] like Figure 1 , Figure 2 As shown, a water-immersion fire-proof and electric shock-proof protector includes a protector body 1. A plurality of reinforcing ribs 4 are arranged at the stepped corners of the protector body 1. A control switch (not shown in the figure) is arranged on the inner side of the protector body 1. A protector cover plate 2 is fixedly covered on the upper side of the protector body 1 by screws 8. When in use, the protector body 1 can be sealed by the protector cover plate 2 to protect the control switch.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a sealing component 3 for sealing the screw 8 is provided on the protector cover 2, and the sealing component 3 includes a sealing cover 301 connected to the upper side of the protector cover 2 through a rotating shaft 305, and the sealing cover 301 is covered on the upper side of the screw 8. A screw hole 6 matching the screw 8 is opened on the upper side of the protector cover 2, and a cover groove 5 located on the outer side of the screw hole 6 is opened on the upper side of the protector cover 2. The sealing cover 301 is clamped with the cover groove 5 after being closed around the rotating shaft 305. A sealing groove 7 is opened on the upper side of the protector cover 2 and located on the outer side of the screw 8, and a sealing ring 302 is fixedly arranged on the inner side of the sealing cover 301 and is clamped into the sealing groove 7 after the sealing cover 301 is closed. The sealing ring 302 and the sealing groove 7 can adopt a circular structure, and the sealing ring 302 can be made of rubber and the thickness of the sealing ring 302 can be slightly larger than the width of the sealing groove 7. When in use, when the screw 8 passes through the screw hole 6 and the protector cover 2 is fixed on the upper side of the protector body 1, the sealing cover 301 is then rotated so that the sealing cover 301 covers the inner side of the cover groove 5. After covering, the sealing ring 302 on the inner side of the sealing cover 301 is inserted into the inner side of the sealing groove 7, so that the screw 8 can be sealed to prevent air from contacting the screw 8, causing the screw 8 to rust and create gaps, thereby preventing water vapor from entering the interior of the protector through the rusted gaps and affecting the safety of the protector. At the same time, it can effectively prevent the screw 8 from rusting and facilitate disassembly for convenient maintenance.

[0022] like Figure 3 , Figure 4 As shown, a groove 9 is provided on one side of the cover groove 5, a first magnet 10 is fixedly provided inside the groove 9, and a second magnet 303 is fixedly provided on the inner edge of the sealing cover 301 to cooperate with the first magnet 10 for attraction. When in use, the sealing cover 301 can be tightly covered on the inner side of the cover groove 5 through the attraction between the first magnet 10 and the second magnet 303, so that the sealing cover 301 is covered more tightly and the sealing effect is improved.

[0023] Example 2

[0024] A further improvement on the basis of Example 1 is that Figure 1 , Figure 3 As shown in FIG. 1 , a cross block 304 is provided on the inner side of the sealing cover 301 and is located on the inner side of the sealing ring 302. When the sealing cover 301 is closed, the cross block 304 is engaged with the cross groove on the upper side of the screw 8. When in use, when the sealing cover 301 is closed, the cross block 304 on the inner side of the sealing ring 302 is engaged with the cross groove on the upper side of the screw 8, which can prevent the screw 8 from loosening when it is vibrated, thereby improving the positioning effect of the screw 8.

[0025] It should be noted that when using this water-immersion fire-proof and electric shock-proof protector, the protector cover 2 is covered on the upper side of the protector body 1 by means of screws 8, and then the sealing cover 301 is rotated so that the sealing cover 301 covers the inner side of the cover groove 5. After covering, the sealing ring 302 on the inner side of the sealing cover 301 is inserted into the inner side of the sealing groove 7, so that the screw 8 can be sealed to prevent air from contacting the screw 8, causing the screw 8 to rust and create gaps, thereby preventing water vapor from entering the interior of the protector through the rusted gaps to prevent affecting the safety of the protector. At the same time, it can effectively prevent the screw 8 from rusting and facilitate disassembly for convenient maintenance.

[0026] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
