[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] Example 1
[0024] Reference Figure 1 , 2This is the first embodiment of the present invention, which provides a modular box-type power distribution switch monitoring terminal that is easy to maintain. It includes a box body 1, a door 3 hinged to one side of the box body 1, a top plate 2 fixedly connected to the top of the box body 1, mounting frames 9 fixedly installed on the inner walls of the upper two sides of the box body 1, and mounting strips 4 provided on the inner wall of the lower section of the box body 1. A movable cavity 42 is formed in the middle of the mounting strip 4 near the inner wall of the box body 1, and transmission cavities are formed at both ends of the mounting strip 4 near the inner wall of the box body 1. Fixed pressure lines 6 are symmetrically arranged on the upper and lower sides of the mounting strip 4, each fixed pressure line 6 fixed to the inner wall of the box body 1. Movable pressure lines 7 are movably provided on the side of the fixed pressure lines 6 away from the inner wall of the box body 1. Multiple lines are arranged on the opposite sides of the movable pressure lines 7 and the fixed pressure lines 6. The groove 12; connecting strips 8 are respectively provided at both ends of the movable pressure line 7. The middle of the connecting strip 8 is threaded with an adjusting screw 11. The adjusting screw 11 extends through the mounting strip 4 to the transmission cavity and is connected to the driven bevel gear 58. An adjusting knob 51 is movably provided in the middle of the mounting strip 4. The adjusting knob 51 extends to the movable cavity 42 and is connected to the driving bevel gear 52. A transmission structure is provided between the driving bevel gear 52 and the driven bevel gear 58. The transmission structure includes a transmission rod 56 and driven bevel gears 57 provided at both ends of the transmission rod 56. The transmission rod 56 connects the movable cavity 42 and the transmission cavity along the inside of the mounting strip 4, and the driven bevel gears 57 at both ends of the transmission rod 56 are meshed with the driving bevel gear 52 and the driven bevel gear 58, respectively.
[0025] A limiting plate 111 is provided at the end of the adjusting screw 11 away from the connecting strip 8. The limiting plate 111 prevents the connecting strip 8 from detaching and limits the connecting strip 8. Mounting frames 9 are also fixedly installed on the inner wall of the housing 1, and the required parts are placed inside the mounting frames 9. Multiple mounting holes 41 are opened on both sides of the mounting strip 4. Bolts are used on the mounting strip 4 to install the power distribution switch in conjunction with the mounting holes 41. The wire groove 12 is a semi-cylindrical groove, and the two wire grooves 12 on both sides form a cylindrical groove, which facilitates the compaction and fixing of the wires used in the components, preventing the wires from becoming tangled. The adjusting screw is driven by operating the adjusting component 5. When rod 11 rotates, the two adjusting screws 11 drive the connecting strip 8 to move through the threaded structure. The connecting strip 8 drives the fixed movable pressure line 7 to move away from the fixed pressure line 6, thereby creating a certain gap between the movable pressure line 7 and the fixed pressure line 6, which facilitates the wire to pass through. The installed wire passes between the movable pressure line 7 and the fixed pressure line 6 and is inserted into the wire groove 12. Then, the adjusting component 5 is operated in the opposite direction again, driving the movable pressure line 7 to move towards the fixed pressure line 6. After the movable pressure line 7 and the fixed pressure line 6 are tightly attached, the wire is pressed and fixed to prevent the wire from loosening.
[0026] Example 2
[0027] Reference Figure 1-5This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, a threaded rod 10 is vertically arranged in the movable cavity 42. The two ends of the threaded rod 10 are respectively rotatably embedded in the inner walls of the upper and lower sides of the box 1. A movable block 13 is sleeved on the threaded rod 10. The rear side of the movable block 13 is in close contact with the inner wall of the box 1. Multiple LED lights 14 are arranged on the front side of the movable block 13.
[0028] For ease of operation, the surface of the movable block 13 is also provided with a switch and a charging interface. The movable block 13 contains a rechargeable battery. The connection end of the rechargeable battery is connected to the switch and the LED light 14 in series via wires. The connection end of the rechargeable battery is also connected to the charging interface via wires.

[0030] The adjustment knob 51 has two control methods. By pressing the adjustment knob 51 inward, the slot 531 is disengaged from the locking strip 512, and the second driving bevel gear 54 and the third driven bevel gear 55 are engaged. At this time, rotating the adjustment knob 51 will cause the second driving bevel gear 54 to drive the third driven bevel gear 55 to rotate. The third driven bevel gear 55 will drive the threaded rod 10 to rotate. The threaded rod 10 will drive the movable block 13 to slide against the inner wall of the housing 1 through the threaded structure. At the same time, the LED light 14 will be activated, which will illuminate the inside of the housing 1, providing a convenient inspection field for maintenance personnel and facilitating maintenance operations.
[0031] By pulling the adjustment knob 51 outward, the snap-fit groove 531 and the snap-fit strip 512 are adapted and connected, and the driving bevel gear 2 54 and the driven bevel gear 3 55 are disengaged. At this time, rotating the adjustment knob 51 will drive the driving bevel gear 1 52 to rotate through the snap-fit strip 512. The driving bevel gear 1 52 will drive the adjustment screw 11 to rotate. The two adjustment screws 11 will drive the connecting strip 8 to move through the threaded structure. The connecting strip 8 will drive the fixed movable pressure line 7 to move toward or away from the fixed pressure line 6, thereby realizing the loosening and clamping of the wire.
[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
