Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] like Figures 1-7 As shown, a detachable external waterproof battery box according to this embodiment includes an outer box 1, an inner box 2, an outer box cover 3, and an inner box cover 4. The top of the outer box 1 is open. The outer box cover 3 is detachably connected to the outer box 1, and the inner box cover 4 is detachably connected to the inner box 2. The outer box 1 is provided with a connection hole 11, through which screws can connect the outer box 1 to a measuring instrument. The outer box 1 has a compartment 12 for accommodating the inner box 2. The outer box 1 is provided with a charging port 13 and a power interface 14. The inner box 2 is provided with a power supply 21, a circuit board 22, a charging connector 23, and a power connector 24. The power supply 21 is a rechargeable battery or a rechargeable lithium battery. The charging connector 23 is correspondingly arranged with the charging port 13, and the power connector 24 is correspondingly arranged with the power interface 14. The charging connector 23, the power connector 24, the power supply 21, and the circuit board 22 are electrically connected.

[0029] The working principle of this utility model is as follows: The inner box 2, containing a power supply 21, a circuit board 22, a charging connector 23, and a power connector 24, is inserted into the compartment 12 of the outer box 1. The charging connector 23 corresponds to the charging port 13 on the outer box 1, and the power connector 24 corresponds to the power interface 14 on the outer box 1. The outer box cover 3 is placed over the opening at the top of the outer box 1, and the outer box cover 3 is connected to the outer box 1 using screws. The outer box 1 is connected to the measuring instrument using screws, and the power connector 24 is connected to the connector of the measuring instrument, thus realizing the connection between the external battery box and the measuring instrument.

[0030] The inner box 2 is provided with a pull strap 25 at the top, which can be used to pull the inner box 2 out from the compartment 12 of the outer box 1 for easy battery replacement.

[0031] The outer box cover 3 is equipped with a spring 31 inside. After the outer box cover 3 is installed at the opening at the top of the outer box body 1, the spring 31 can press the inner box body 2 to fix the inner box body 2.

[0032] The inner wall of the outer box 1 and the outer wall of the inner box 2 are provided with a foolproof structure, that is, the inner wall of the outer box 1 and the outer wall of the inner box 2 are asymmetrical structures, such as the corner of one inner wall / outer wall being a right angle and the corner of one inner wall / outer wall being a rounded corner, to prevent errors when the inner box 2 is inserted into the outer box 1.

[0033] The opening of the outer box 1 has a stepped structure, that is, the middle part of the opening of the outer box 1 protrudes beyond the edge of the opening to prevent water from entering the interior of the outer box 1. The opening is provided with a drainage groove so that water can be discharged from the drainage groove after watering.

[0034] The outer box cover 3 is connected to the outer box body 1 by quick-release screws, which facilitates the quick removal and installation of the outer box cover 3.

[0035] The power connector 24 is a blade-type power connector. When the inner box 2 is pulled out from the outer box 1, it is easy for the power connector 24 to be pulled out from the power interface 14. The power interface 14 is located on the mounting surface of the outer box 1, which is the side of the outer box 1 that contacts the measuring instrument. This facilitates the connection of the power interface 14 to the measuring instrument and also makes it easy to hide the power interface 14 between the power interface 14 and the measuring instrument. After the outer box 1 is connected to the measuring instrument or other equipment, a sealing ring is provided on the mounting surface of the outer box 1 to prevent water from splashing.

[0036] The charging port 13 is located at the bottom of the outer casing 1. The charging port 13 is equipped with a waterproof plug to protect it from water. The charging port 13 is a USB interface, which facilitates the export of stored data.

[0037] The inner box 2 is equipped with a Bluetooth module, which is electrically connected to the circuit board 22. The Bluetooth module facilitates the connection of the battery box with other electronic devices via Bluetooth.

[0038] The outer box 1 has several ribs 15 inside its compartment 12. The ribs 15 are perpendicular to the opening of the outer box 1. From the opening of the outer box 1 to the inside of the compartment 12, the thickness of the ribs 15 gradually increases at the end near the opening of the outer box 1. After the inner box 2 is inserted into the compartment 12, it is held in place by the ribs 15, thus preventing the inner box 2 from shaking.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
