The box body 1 is a rectangular parallelepiped and is made of high-strength aluminum alloy, which has the advantages of high strength and light weight. One side of the box body 1 is open, and countersunk holes 13 are provided at the four corners of the open side of the box body 1. Corresponding connecting rods 34 are provided at the bottom corners of the mounting frame 3, aligned with the positions of the countersunk holes 13. The connecting rods 34 are provided with threaded holes at the ends away from the mounting frame 3. The mounting frame 3 is detachably mounted at the opening of the box body 1 by connecting screws 5. At this time, the connecting rods 34 of the mounting frame 3 are inserted into the countersunk holes 13 of the box body 1 one by one, and a connecting screw 5 is inserted into each countersunk hole 13. The threaded rod of the connecting screw 5 is screwed into the threaded hole of the connecting rod 34. An end column 51 is provided at the bottom of the threaded rod of the connecting screw 5, and a screw end 52 is provided at the bottom of the end column 51. The end column 51 is a cylindrical structure, and its diameter is the same as the aperture of the countersunk hole 13, so that the connecting screw 5 can stably connect the box body 1 to the mounting frame 3.

[0030] like Figure 1 、 Figure 5 and Figure 6 As shown, an inspection opening 31 is provided in the middle of the mounting frame 3 to facilitate inspection of the entire internal structure of the test terminal box. A stopper 32 for mounting the flip cover 4 is provided along the top of the mounting frame 3, surrounding the inspection opening 31. Adapter grooves 33 are symmetrically provided on the stopper 32. Adapter shafts 43 are symmetrically provided on either end of the flip cover 4. The adapter shafts 43 are rotatably connected to the adapter grooves 33, allowing the flip cover 4 to rotate and thereby open the inspection opening 31. A pull groove 42 is provided in the middle of the end surface of the flip cover 4 away from the adapter shaft 43. This pull groove 42 facilitates the opening of the flip cover 4. Stopper protrusions 41 are symmetrically provided on either side of the pull groove 42 to facilitate the mutual restraint between the flip cover 4 and the mounting frame 3.

[0031] like Figure 2 、 Figure 3 and Figure 8 As shown, a wire hole is provided on the combined wall opposite the opening of the box body 1, and an adapter 12 is provided in this hole. The adapter 12 is hollow and has an external thread structure on its outer wall. A connecting cap 6 is threadedly mounted on the external thread structure of the adapter 12.

[0032] like Figure 1 、 Figure 3 and Figure 4As shown, a limited telescopic assembly 2 is symmetrically positioned on both sides of the box body 1. Telescopic openings 11, corresponding to the limited telescopic assembly 2, are symmetrically positioned on both side walls of the box body 1. The limited telescopic assembly 2 includes a telescopic tongue 21 and a mounting box 22. The mounting box 22 is mounted inside the box body 1. One end of the telescopic tongue 21 is connected to the mounting box 22, while the other end of the telescopic tongue 21 protrudes out of the mounting box through the telescopic opening 11. A pull rod 212 is positioned in the middle of the end of the telescopic tongue 21 facing the mounting box 22, and a pull ring 213 is positioned at the end of the pull rod 212. The cooperation between the pull rod 212 and the pull ring 213 facilitates the retraction of the telescopic tongue 21 when removing the test terminal box. Multiple return springs 211 are symmetrically positioned along the pull rod 212 on the end of the telescopic tongue 21 facing the mounting box 22. This allows the telescopic tongue 21 to retract when pressed when the test terminal box is inserted and installed, and automatically reset when no longer pressed, thereby achieving the purpose of limiting the position of the test terminal box and the body. Mounting box 22 is equipped with fixing legs 221 on either side, with fixing holes 222 located in the middle. These legs 221 and holes 222 facilitate bolting to secure mounting box 22. A through-hole 223 is located in the center of mounting box 22, through which a pull rod 212 passes. The telescopic tongue 21 is retractable within mounting box 22. The box body 1 cooperates with the telescopic limiter assembly 2, ensuring that the entire test terminal box is positioned relative to the locomotive during embedded installation, ensuring a stable installation.

[0033] Working principle: When in use, fix the circuit board required for the test terminal box inside the box body 1, and pass the wires into the box body 1 to connect with the circuit board. Install the limit telescopic assembly 2 on the telescopic opening 11, then fix the installation frame 3 to the top opening of the box body 1 through the connecting screws 5, and install the flip cover 4. Then embed and install the entire test terminal box. During the embedded installation, the telescopic tongue 21 will be squeezed and retracted into the inside of the installation box 22. When the telescopic tongue 21 moves to the corresponding slot on the locomotive, the telescopic tongue 21 will be stuck in the slot under the action of the reset spring 211, so that the entire test terminal box is embedded and installed on the body. When the test terminal box needs to be disassembled, just open the flip cover 4, and then pull the two pull rings 213 at the same time to retract the telescopic tongue 21 to the inside of the installation box 22. After that, the test terminal box can be easily removed.

[0034] In summary, compared with the prior art, the present invention adopts an embedded installation design and provides a limited telescopic assembly 2, eliminating the need for a mounting bracket, reducing costs, and simplifying the installation process. The present invention adopts a miniaturized design, with the box body made of high-strength aluminum alloy. While maintaining structural strength, the structure is reduced in size and weight. The present invention also adopts a flip-up design, which improves the convenience of use and maintenance.

[0035] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
