[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model is a low-voltage measurement and control terminal that is easy to assemble, including a terminal housing. A control panel is provided at one end of the outer surface of the terminal housing. A connecting rail is provided on one side of the outer surface of the terminal housing, and a connecting strip is provided on the other side of the terminal housing. The connecting rail and the connecting strip are symmetrically distributed. The connecting strip and the connecting rail cooperate with each other. A connecting structure is provided inside the connecting rail. An assembly strip is provided at one end of each side of the terminal housing. An assembly groove is formed on the surface of the assembly strip, and a limit structure is provided inside the assembly groove.
[0008] The present invention is further configured such that a connecting rod is fixed inside the connecting track, a pop-out spring is sleeved on the surface of the connecting rod, and a through hole is formed on the surface of the connecting strip to cooperate with the connecting rod.
[0009] The present invention is further configured such that the connecting structure includes a mounting strip, the mounting strip is fixedly installed on one side of the terminal housing, and the two ends of the mounting strip are fixedly connected to two connecting rails.
[0010] The present invention is further configured such that both ends of the mounting strip are provided with movable grooves, one end of the movable groove is movably inserted into a limiting block, one end of the limiting block is movably inserted into the interior of the connecting rail, one side of the upper end of the limiting block is inclined, one side of the connecting strip is provided with a locking hole that cooperates with the limiting block, and one side of the limiting block is fixedly installed with a return spring.
[0011] The present invention is further configured such that an installation groove is provided in the middle of the installation strip, the two ends of the installation groove are connected to the movable groove, and an adjusting rod is movably inserted into both ends of the installation groove.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0027] like Figures 1 to 4 As shown, this embodiment provides a conveniently assembled low-voltage monitoring and control terminal, including a terminal housing 100. A control panel 200 is provided at one end of the outer surface of the terminal housing 100. A connecting rail 300 is provided on one side of the terminal housing 100, and a connecting strip 400 is provided on the other side of the terminal housing 100. The connecting strip 400 and the connecting rail 300 are symmetrically distributed and cooperate with each other. A connecting structure is provided inside the connecting rail 300, including a mounting strip 320. 20 is fixedly installed on one side of the terminal housing 100. The two ends of the mounting strip 320 are fixedly connected to two connecting rails 300. Both ends of the mounting strip 320 are provided with movable grooves. One end of the movable groove is movably inserted into a limit block 321. One end of the limit block 321 is movably inserted into the interior of the connecting rail 300. One side of the upper end of the limit block 321 is inclined. One side of the connecting strip 400 is provided with a card hole 410 that cooperates with the limit block 321. A return spring 322 is fixedly installed on one side of the limit block 321.
[0028] In this embodiment, when the two terminal housings 100 are connected, the connecting strip 400 is inserted into the interior of the connecting track 300. When the connecting strip 400 contacts the limiting block 321, the limiting block 321 is squeezed into the interior of the movable groove, compressing the reset spring 322, so that the limiting block 321 is completely retracted into the interior of the movable groove. When the card hole 410 moves to the position of the limiting block 321, the limiting block 321 pops out under the action of the reset spring 322 and inserts into the interior of the card hole 410, so that the connecting strip 400 is limited inside the connecting track 300, thereby facilitating the connection between the terminal housings 100.
[0029] like Figure 3 and Figure 4 As shown, this embodiment provides a conveniently assembled low-voltage measurement and control terminal. The mounting strip 320 has a mounting groove in the middle, and the two ends of the mounting groove are connected to the movable groove. Adjusting rods 323 are movably inserted through both ends of the mounting groove. One end of the adjusting rod 323 extends into the interior of the movable groove and is fixedly connected to the limiting block 321. A sliding groove 324 is provided in the middle of one side of the surface of the mounting strip 320. Sliding blocks 325 are movably inserted through both ends of the sliding groove 324. One end of each of the two sliding blocks 325 is fixedly connected to the two adjusting rods 323 respectively.
[0030] In this embodiment, when disassembling, the user pulls the sliders 325 at both ends of the slide groove 324 toward the middle of the slide groove 324. The sliders 325 drive the limiting block 321 to move through the adjusting rod 323. The limiting block 321 is pulled out from the inside of the locking hole 410 and disengages from the connecting strip 400, so that the connecting strip 400 can be pulled out from the inside of the connecting track 300, thereby facilitating the quick disassembly of the terminal housings 100.
[0031] The connecting rail 300 has a connecting rod 310 fixed inside, and a spring 311 is fitted onto the surface of the connecting rod 310. The connecting strip 400 has a through hole that mates with the connecting rod 310. When the connecting strip 400 is inserted into the connecting rail 300, it fits onto the surface of the connecting rod 310 and compresses the spring 311. When the limiting block 321 disengages from the locking hole 410, the spring 311 pushes the connecting strip 400 out of the connecting rail 300, facilitating the separation of the connecting strip 400 from the connecting rail 300.
[0032] like Figure 2 and Figure 5 As shown, this embodiment provides a conveniently assembled low-voltage measurement and control terminal. Each end of the terminal housing 100 has an assembly strip 500. The surface of the assembly strip 500 has an assembly groove 510. The interior of the assembly groove 510 has a limiting structure, including a groove 520. The groove 520 is located on one side of the assembly groove 510, and its width is greater than the width of the assembly groove 510. One end of the groove 520 has a limiting rack 521. Two moving blocks 530 are slidably mounted on one side of the assembly strip 500. Both sides of the moving block 530 have a locking rod 532 that movably passes through it. One end of the locking rod 532 extends into the interior of the groove 520 and is fitted with a limiting ring 531. The limiting ring 531 engages with the limiting rack 521. A locking spring 533 is sleeved on the surface of the locking rod 532, and one end of the locking rod 532 has a pressure ring 534.
[0033] In this embodiment, when the terminal housing 100 is installed at the point of use, the user pulls the pressure ring 534, which moves the locking rod 532. The locking rod 532 moves the limiting toothed ring 531, compressing the locking spring 533. This causes the limiting toothed ring 531 to disengage from the limiting rack 521, allowing the moving block 530 to move along one side of the mounting strip 500. When it moves to the hole at the installation location, the limiting toothed ring 531 and the locking rod 532 return to their original positions under the action of the locking spring 533. The limiting toothed ring 531 engages with the limiting rack 521, limiting the position of the moving block 530. The mounting bolt can pass through the moving block 530 and the limiting toothed ring 531 to connect with the hole at the installation location. The moving block 530 cannot move because of the limiting toothed ring 531 and the limiting rack 521, thus preventing the terminal housing 100 from moving after installation and enhancing the stability of the terminal housing 100.
