[0022] 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.

[0023] See also Figure 1-4 The utility model provides a power box with a power interface protection structure, including a power box body 1, an interface 2, a base 3 and a top cover 4, the interface 2 is arranged on the power box body 1, the base 3 is arranged on the interface 2, a limiting groove 31 is provided on the base 3, the top cover 4 is connected to the base 3, a limiting column 42 is provided in the top cover 4, and the bottom end of the limiting column 42 extends out of the top cover 4, and the limiting column 42 is slidably connected to the limiting groove 31.

[0024] The base 3 is arranged on the interface 2, and the top cover 4 is located on the base 3, so the plug connected to the interface 2 can be effectively fixed. After the interface 2 on the power box body 1 is fixed to the plug, the instability of the power supply caused by the looseness of the interface 2 can be reduced, and the stability and reliability of the power supply can be improved. After the interface 2 on the power box body 1 is fixed to the plug, poor contact or short circuit of the interface can be prevented, which greatly improves the safety of the power box body 1. After the interface 2 on the power box body 1 is fixed to the plug, the interface can be effectively prevented from being worn due to frequent plugging and unplugging, thereby extending the service life of the power box body 1.

[0025] At the same time, after the plug and the interface 2 are fixed, the power loss can be effectively reduced, the energy utilization efficiency can be improved, and unnecessary power waste can be reduced. Because, when the plug and the interface 2 are fixed, the connection between the power cord and the power box body 1 will become very stable, and power loss will not be caused by looseness, which can improve energy utilization efficiency and reduce unnecessary power waste. In addition, the fixation of the plug and the interface 2 can also reduce the failure rate and improve the operating reliability of the power box body 1. In the existing power box body 1, due to the frequent plugging and unplugging of the interface 2 and the plug, it is easy to cause poor contact, which in turn causes failures. After the plug and the interface 2 of the power box body 1 are fixed, this situation can be avoided, thereby reducing the failure rate, improving the operating reliability of the power box body 1, and thus reducing the failure rate. At the same time, the fixation of the plug and the interface 2 can also improve the work efficiency of the staff and reduce maintenance time and cost. In the existing power box body 1, due to the frequent plugging and unplugging of the interface 2 and the plug, it is easy to cause wear and tear, which in turn causes failures, which requires maintenance by the staff. After the plug and the interface 2 of the power box body 1 are fixed, this situation can be reduced, thereby improving the work efficiency of the staff and reducing maintenance time and cost. At the same time, the appearance of the power box body 1 is more neat, which can improve the overall aesthetics of the device. Through the connection between the top cover 4 and the base 3, the connection between the plug and the interface 2 can be dustproof and waterproof, further ensuring the normal operation of the power box body 1.

[0026] During the specific operation, the plug can be fixed on the interface 2 through the connection between the top cover 4 and the base 3. When the plug needs to be removed, the top cover 4 is moved upward to drive the limiting column 42 to move out of the inner cavity of the limiting groove 31, thereby separating the top cover 4 and the base 3.

[0027] As an optional implementation, a power supply box with a power interface protection structure further includes a fixing mechanism 5, the fixing mechanism 5 includes a connecting plate 51, a spring 52, a button 53 and a clamping block 54;

[0028] A card slot 32 is opened on the limiting groove 31, the connecting plate 51 is arranged in the limiting column 42, the spring 52 is arranged between the connecting plate 51 and the limiting column 42, the spring 52 provides an elastic force for the connecting plate 51 to stay away from the top cover 4, the button 53 is connected to the connecting plate 51, and the end of the button 53 away from the connecting plate 51 extends out of the top cover 4, the card block 54 is connected to the connecting plate 51, and the end of the card block 54 away from the connecting plate 51 extends into the card slot 32.

[0029] During the specific operation, the button 53 is pressed to move the connecting plate 51, and the spring 52 is compressed to move the block 54 out of the inner cavity of the slot 32, thereby releasing the fixation of the top cover 4. The top cover 4 is moved upward to drive the limiting column 42 to move out of the inner cavity of the limiting slot 31, and the top cover 4 and the base 3 can be quickly separated. During installation, the limiting column 42 is extended into the inner cavity of the limiting slot 31 and moved downward. The block 54 is forced to re-enter the inner cavity of the slot 32 to connect and fix the top cover 4 and the base 3.

[0030] By quickly disassembling the top cover 4 and the base 3, the staff can easily remove the plug, saving time and effort. The quick disassembly of the top cover 4 and the base 3 can significantly improve work efficiency, eliminating time-consuming steps such as manually tightening screws and adjusting positions in traditional disassembly and assembly methods. If the top cover fails, it can be quickly disassembled and assembled, which is convenient for maintenance and replacement, reducing maintenance time and cost. The quick disassembly of the top cover 4 and the base 3 can reduce errors caused by improper operation or misunderstanding of operating steps, and improve the accuracy of operation.

[0031] As an optional implementation, the cross section of the block 54 is trapezoidal.

[0032] The cross section of the block 54 is a trapezoid, and when the limiting column 42 is inserted into the limiting groove 31, the block 54 fits with the limiting groove 31, and the block 54 can be automatically retracted into the limiting column 42, and the spring 52 is compressed. When the block 54 corresponds to the groove 32, the spring 52 pops out and pushes the block 54 into the inner cavity of the groove 32. This makes installation more convenient.

[0033] As an optional implementation, the number of interfaces 2 is at least three. The number of interfaces 2 can determine the number of mounting bases 3 and top covers 4.

[0034] As an optional implementation, the height of the limiting column 42 extending out of the top cover 4 is the same as the height of the inner cavity of the limiting groove 31 .

[0035] The height of the limiting column 42 out of the top cover 4 is the same as the height of the inner cavity of the limiting groove 31. This ensures that when the limiting column 42 extends into the limiting groove 31, the top cover 4 can be tightly fitted with the base 3. This can improve the sealing effect between the top cover 4 and the base 3.

[0036] As an optional implementation, a cable arrangement groove 41 is provided on the top cover 4 .

[0037] The cable trough 41 can make the power box on the plug better extend out of the inner cavity of the top cover 4, avoiding the phenomenon of bending of the power box on the plug. When the wire is bent, the metal conductor inside it will be stretched, which may cause metal fatigue or even breakage. This will not only reduce the transmission efficiency of the wire, but also cause power loss. Therefore, avoiding the bending of the wire can effectively extend the service life of the wire, reduce the frequency of replacing the wire, and save maintenance costs. At the same time, the bending of the wire may cause poor contact of the wire, causing leakage or short circuit, and in severe cases may cause fire and threaten personal safety. Therefore, the cable trough 41 can effectively avoid the bending of the wire.

[0038] As an optional implementation, there are two cable slots 41 . The two cable slots 41 allow the plug to be connected to the interface 2 .

[0039] As an optional implementation, a sealing gasket 6 is provided in the cable groove 41. By providing the sealing gasket 6 in the cable groove 41, the entry of dust and splashing water can be reduced.

[0040] The sealing gasket 6 is made of polytetrafluoroethylene, which is a high-performance polymer with excellent corrosion resistance, high and low temperature resistance and good electrical insulation.

[0041] Therefore, through the above technical solution, the power box with the power interface protection structure can effectively prevent the plug from being separated from the interface 2, and improve the fixing effect of the plug and the interface 2. It can also reduce the splashing of dust and water stains entering the top cover 4 and the base 3, thereby protecting the plug and the interface 2.

[0042] It should be noted that, in this document, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
