The expansion block 44 is slidably connected with the expansion channel 411, the expansion block 44 is provided with a limiting block 441, the expansion channel 411 is provided with a sliding groove 412, the limiting block 441 is located in the sliding groove 412, and the limiting block 441 is slidably connected with the sliding groove 412. The connecting column 7 is connected with the second slide rail 32 through the compression block 45, the side of the connecting column 7 is provided with a threaded hole, and the connecting part 451 is connected with the threaded hole on the side of the connecting column 7. The bottom of the slide rail frame 3 is provided with a mounting plate 6 for connecting the ceiling plate 1, the two sides of the locking device 4 are provided with mounting pieces 414 for connecting the access cover plate 2, and the bottom of the adjusting cap 421 is provided with a wrench interface 422.

[0035] During installation, install the slide rail frame 3 to the ceiling panel 1, open a hole in the inspection port cover 2 that is the same shape as the bottom of the locking device 4 shell 41, insert the bottom of the locking device 4 into the hole, let the mounting pieces 414 on both sides of the shell 41 fit with the top surface of the inspection port cover 2, fix the mounting pieces 414 to the inspection port cover 2 with screws, install the connecting column 7 on the top of the inspection port cover 2, align the screw channel 442 on the locking device 4 with the first slide rail 31 of the slide rail frame 3, and insert the clamping block 45 from the other side of the slide rail frame 3, let the connecting part 451 and the sliding part 452 pass through the first slide rail 31, and the connecting part 451 is connected to the screw channel 442 through a thread, so that the sliding part 452 of the clamping block 45 is located on the first slide rail 31, and the clamping block 453 of the clamping block 45 and the shell 41 are located on both sides of the slide rail frame 3. Then, another pressing block 45 is moved from the other side of the slide rail frame 3 , and the connecting portion 451 and the sliding portion 452 are passed through the second slide rail 32 . The connecting portion 451 is connected to the threaded hole on the side of the connecting column 7 through a thread.

[0036] When it is necessary to open the inspection port cover 2, the operator uses an ordinary wrench 5 to insert it from the bottom of the inspection port cover 2 into the wrench interface 422 of the adjusting cap 421 at the bottom of the locking device 4, where the wrench interface 422 is a groove corresponding to the hexagonal wrench. Turn the wrench 5 to rotate the adjusting cap 421 and the worm 42 as a whole. The multiple threads on the worm 42 drive the worm wheel 431 to rotate, and the worm wheel 431 drives the screw 43 to rotate. The end of the screw 43 is located in the screw channel 442 of the telescopic block 44, and the telescopic block 44 is located in the telescopic channel 411 of the shell 41. The limit block 441 on the telescopic block 44 is located in the slide groove 412 on the telescopic channel 411. The limit block 441 and the slide groove 412 limit the rotation of the telescopic block 44 around the axis in the telescopic channel 411, so that the telescopic block 44 can only slide along the axis direction in the telescopic channel 411. Therefore, when the screw 43 rotates, the thread between the screw 43 and the screw channel 442 will cause the telescopic block 44 to move in the telescopic channel 411 in the direction away from the worm gear 431. Under the movement of the telescopic block 44, the pressing block 453 of the clamping block 45 moves in the direction away from the slide rail frame 3. When the pressing block 453 has no contact with the slide rail frame 3, the inspection port cover 2 is pushed upward along the "L"-shaped track of the first slide rail 31, and then pushed in the horizontal direction to open the inspection port cover 2. When the inspection port cover 2 needs to be locked after being closed, the adjusting cap 421 is rotated in the reverse direction with the wrench 5 so that the pressing block 453 and the housing 41 clamp the slide rail frame 3 .

[0037] The present invention provides an assembled modular top surface inspection structure that adopts a modular integral component sliding rail inspection port cover opening method, which saves the inspection port cover opening space and has a cover locking function. It can effectively solve the problem that when the indoor space pressure is greater than the internal pressure of the ceiling top cavity, negative pressure occurs and the top inspection port plate is pushed upward.
