Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Specific examples are given below.

[0023] See also Figure 1 to Figure 6In an embodiment of the utility model, a cable tray cover structure includes a tray body 1, a tray cover 2, a rotation drive mechanism 3, a clamping mechanism 4 and a reinforcing rib 5. The tray body 1 is provided with a tray cover 2, and a clamping mechanism 4 is provided on the lower side of the tray cover 2. The tray cover 2 is rotatably connected with a rotation drive mechanism 3 for driving the clamping mechanism 4 to rotate. A plurality of reinforcing ribs 5 are fixed to the lower side of the tray cover 2. The strength of the tray cover 2 is strengthened by the reinforcing ribs 5. The tray body 1 and the tray cover 2 are both made of stainless steel. The outer sides of the tray body 1 and the tray cover 2 are sprayed with fire retardant paint to improve safety. The rotation drive mechanism 3 includes: a rotating block 301, a transmission rod 302 and a first bevel gear 303. The rotating block 301 is rotatably connected to the tray cover 2. The top of the rotating block 301 is flush with the top of the bridge cover 2 (that is, the rotating block 301 does not form a protrusion on the bridge cover 2 to ensure that the top surface of the bridge cover 2 is flat), a transmission rod 302 is fixed to the lower side of the rotating block 301, and a first bevel gear 303 is installed at the bottom of the transmission rod 302. A storage groove 3011 is provided in the rotating block 301, and a handle 3012 is installed in the storage groove 3011. The handle 3012 is rotatably connected to the rotating block 301 through a pin shaft 3013. When the rotating block 301 needs to be rotated, the handle 3012 is erected from the storage groove 3011 with a finger, and then the handle 3012 is rotated by hand, and the rotating block 301 is driven to rotate by the handle 3012, and the transmission rod 302 and the first bevel gear 303 are driven to rotate by the rotating block 301.

[0024] The clamping mechanism 4 includes: a bidirectional screw 401, a first external thread 402, a second external thread 403, a first threaded sleeve 404, a second threaded sleeve 405, a limiting rod 406, a clamping block 407, a second bevel gear 408 and an adapter block 409. The number of the adapter blocks 409 is two. The adapter block 409 is fixed to the lower side of the bridge cover plate 2. The bidirectional screw 401 is rotatably connected between the two adapter blocks 409. The bidirectional screw 401 is provided with a second bevel gear 408 meshing with the first bevel gear 303. The left half of the bidirectional screw 401 is provided with a first external thread 402, and the outer side of the first external thread 402 is provided with a first threaded sleeve 404 matching therewith. The right half of the bidirectional screw 401 is provided with a second external thread 403. A second threaded sleeve 405 matching with the thread 403 is installed on the outer side of the thread 403, and a limiting rod 406 inserted into the bridge cover 2 is fixed on the upper side of the first threaded sleeve 404 and the second threaded sleeve 405. The limiting rod 406 is slidably connected to the bridge cover 2, and a limiting groove 201 for moving the limiting rod 406 is provided on the bridge cover 2. The movement of the first threaded sleeve 404 and the second threaded sleeve 405 is restricted by the limiting rod 406 so that they cannot rotate but can only move in a straight line. A clamping block 407 is fixed on the lower side of the first threaded sleeve 404 and the second threaded sleeve 405, and the rotation directions of the first external thread 402 and the second external thread 403 are opposite, so that when the bidirectional screw 401 rotates, the movement directions of the first threaded sleeve 404 and the second threaded sleeve 405 are opposite.

[0025] Working principle: When using the cable tray cover structure, first cover the tray cover 2 onto the tray body 1, then use your fingers to lift up the handle 3012 from the storage slot 3011, and then rotate the handle 3012 by hand, so that the handle 3012 drives the rotating block 301 to rotate, and the rotating block 301 drives the transmission rod 302 and the first bevel gear 303 to rotate, and the first bevel gear 303 drives the second bevel gear 408 to rotate, and the second bevel gear 408 drives the bidirectional screw 401 to rotate, and the bidirectional screw 401 drives the second bevel gear 408 to rotate. The screw rod 401 is rotated to drive the first threaded sleeve 404 and the second threaded sleeve 405 to move toward each other, and the first threaded sleeve 404 and the second threaded sleeve 405 move toward each other, which drives the two clamping blocks 407 to move toward each other, so that the two clamping blocks 407 are clamped into the interior of the bridge frame body 1, and the bridge frame cover plate 2 is connected and fixed to the bridge frame body 1. Finally, the handle 3012 is retracted into the storage groove 3011. Similarly, when disassembling, the clamping block 407 is separated from the bridge frame body 1, and then the bridge frame cover plate 2 is pulled off.
