Specific embodiment
The application is not limited by following embodiments, can be determined according to the technical solution of the application and actual conditions specific
Embodiment.
Embodiment 1, as shown in Figures 1 to 3, free removal screen cabinet include cabinet body 1；Cabinet body 1 is equipped with the mounting hole of front and back perforation
2, mounting hole 2 is interior to be equipped with left and right two retaining rails 3, drawable sliding rail 4 is matched in retaining rail 3 and by two sliding rails 4
Support has protective device cabinet 5；1 back side of cabinet body is located at 2 two sides of mounting hole and is respectively provided with a terminal block 6, the inside of terminal block 6 and guarantor
Back panel wiring 14 is connected between protection unit cabinet 5.
Protective device cabinet 5 is loaded on sliding rail 4 and can be as sliding rail 4 is along the progress pull of retaining rail 3；Terminal block 6 is fixed
1 back side of cabinet body convenient for tear open, wiring cable；When progress protective relaying device is remodeled, 6 external cabling of terminal block can be retained, remove end
Son 6 back panel wirings 14 of row, recycle 5 specification of protective device cabinet is identical to carry out new and old replacement, finally will be new according to cable feature
Back panel wiring 14 is connect with new protective device cabinet 5；Traditional approach is reduced according to the workload that 50 hours 10 people complete to 37 small
When 4 people complete, working efficiency have originally averagely everyone progress 0.2% is significantly promoted to everyone progress per hour per hour
0.68%, and reduce security risk.
As shown in Figures 1 to 3,4 lower end surface of sliding rail is equipped with rectangle card hole 7；3 lower end surface of retaining rail is fixed with the peace of opening upwards
Barrelling 8, retaining rail 3 are equipped with and the installation matched through-hole of bucket 8；It can slide up and down in installation bucket 8 and be set with positioning tongue 9, it is fixed
Pressure spring 10 is connected between the lower end surface of position tongue 9 and the bucket bottom for installing bucket 8, the top of positioning tongue 9 passes through through-hole and the position of retaining rail 3
In on the motion profile of sliding rail 4, it is arc surface 11, positioning that 9 top of positioning tongue, which corresponds to sliding rail 4 and extracts the side in 2 direction of mounting hole out,
It is vertical jam face 12 that 9 top of tongue, which corresponds to sliding rail 4 to enter the side in 2 direction of mounting hole, and the lower end surface of positioning tongue 9 is fixedly connected with
It is pierced by the pull rod 13 at installation 8 barrels of bottoms of bucket；Protective device cabinet 5 on sliding rail 4 is completely into mounting hole 2, corresponding positioning tongue 9
Matching is caught in rectangle card hole 7.
Sliding rail 4 can be used the existing structures such as drawer rail with retaining rail 3 and be made.When protective device cabinet 5 completely into
When entering in mounting hole 2, matching is caught in rectangle card hole 7 positioning tongue 9 just；At this time due to jam face 12 vertical on positioning tongue 9
In the presence of sliding rail 4 cannot be extracted out outward, opposite with fixed cabinet locked.When needing replacing protective device cabinet 5, under needing manually
Pull rod 13 is drawn, positioning tongue 9 exits rectangle card hole 7, and 4 side of sliding rail can extract out outward；And when sliding rail 4 inwardly pushes, due to positioning
The presence of arc surface 11 on tongue 9, positioning tongue 9 can be automatically into rectangle card holes 7.
