[0060] In the prior art, corresponding threaded holes are usually set on the battery box and the electrical equipment. When the battery box is assembled on the electrical equipment, multiple screws are used to screw into the corresponding threaded holes respectively to fix the battery box and the electrical equipment. Since the battery box is usually square, at least four screws are generally required to fix the battery box and the electrical equipment; when the battery box is removed from the electrical equipment, multiple screws need to be screwed out of the threaded holes respectively to separate the battery box from the electrical equipment; in the prior art, installing the battery box on different electrical equipment requires repeated installation and removal of multiple screws, which takes a long time.

Therefore, in the prior art, the assembly between the battery box and the electrical equipment requires at least four steps, and the disassembly between the battery box and the electrical equipment requires at least four steps; therefore, through the above comparison, compared with the prior art, this embodiment requires fewer steps and takes less time during installation and disassembly, that is, this embodiment solves the technical problem of how to quickly disassemble and assemble the battery box and the electrical equipment in the prior art.

[0062] Furthermore, a threaded hole is provided on the seat body 2031, and the seat body 2031 and the third surface 103 are detachably connected by screws; preferably, a protrusion can be provided on the seat body 2031, and a recess can be provided on the third surface 103, and the protrusion and the recess form a movable snap-fitting relationship; after one side of the seat body 2031 reaches the third surface 103, the protrusion is inserted into the recess, so that a temporary positioning is formed between the seat body 2031 and the third surface 103, and then the screws are installed, which is more convenient.

[0063] Furthermore, in order to enable the first engaging component 203 to achieve the function of repeated engagement, the present embodiment also includes the following technical solutions:

[0064] like Figure 3-4 A strip hole 2038 is provided on the seat body 2031, and the extension direction of the strip hole 2038 is consistent with the extension direction of the spring 2034, and the strip hole 2038 is communicated with the mounting groove 2032; a trigger block 2039 is provided on one side of the lock tongue 2033, and one end of the trigger block 2039 is inserted into the strip hole 2038 and can move along the extension direction of the strip hole 2038.

[0065] In this embodiment, the protrusion 2035 is pushed into the limiting channel 2036, and the trigger block 2039 can be moved along the direction of the spring 2034 pointing to the limiting channel 2036, so that the trigger block 2039 drives the protrusion 2035 to extend out of the limiting channel 2036 through the lock tongue 2033; the protrusion 2035 extends out from the limiting channel 2036, and the trigger block 2039 can be moved along the direction of the limiting channel 2036 pointing to the spring 2034, so that the trigger block 2039 drives the protrusion 2035 to retract into the limiting channel 2036 through the lock tongue 2033; in this embodiment, the position of the protrusion 2035 relative to the limiting channel 2036 can be changed through the trigger block 2039, so that the first engaging component 203 of this embodiment can realize the function of repeated engaging multiple times.

[0066] Furthermore, in order to enable the spring 2034 to expand and contract along the direction of a predetermined straight line, the present embodiment further includes the following technical solutions:

[0068] In this embodiment, the spring 2034 is sleeved on the rod of the guide pin 2037, and the rod of the guide pin 2037 extends along a straight line, thereby guiding the expansion and contraction direction of the spring 2034, that is, the spring 2034 expands and contracts along the straight extension direction of the rod;

[0069] Furthermore, the head of the guide pin 2037 also plays a one-way limiting role on the formation of the locking tongue 2033. When the locking tongue 2033 is too close to the limiting channel 2036, the head of the guide pin 2037 abuts against the outer surface of one side of the seat body 2031.

[0070] Furthermore, this embodiment also includes the following technical solution: a friction portion 3 is provided on the trigger block 2039 .

[0071] In this embodiment, the friction portion 3 may be a plurality of ribs, or a plurality of grooves, or a plurality of spikes arranged on the surface of the trigger block 2039. Preferably, the friction portion 3 is a plurality of ribs arranged on the surface of the trigger block 2039. In this embodiment, by providing the friction portion 3, the friction force between the user's fingers and the trigger block 2039 is increased, thereby preventing the user's fingers from slipping on the trigger block 2039 due to oil stains or sweat.

[0072] Furthermore, this embodiment also includes the following technical solution: a reinforcing rib 4 is provided on the locking tongue 2033 .

[0073] The number of reinforcing ribs 4 can be one or more; in the present embodiment, one end of the locking tongue 2033 is squeezed by the spring 2034, and the other end of the locking tongue 2033 is subjected to the shear force when realizing the locking function, which causes the locking tongue 2033 to be easily broken due to insufficient strength; in the present embodiment, by arranging reinforcing ribs 4 on the locking tongue 2033, the strength of the locking tongue 2033 is increased, thereby avoiding the occurrence of a situation in which the two ends of the locking tongue 2033 are subjected to squeezing force or shear force and breakage due to insufficient strength.

[0074] Furthermore, the box body 8 and the cover body 7 of the present embodiment are both made of magnesium alloy, which is light and low-cost; further, the outer surfaces of the box body 8 and the cover body 7 of the present embodiment are provided with a ceramic coating by a micro-arc oxidation process, making the battery box of the present embodiment more corrosion-resistant and oxidation-resistant.
