The shape of the inside of box 1 can be matched with tray 2, and tray 2 can be directly placed in box 1, and the sliding friction between the structure of tray 2 and box 1 is realized. Considering improving the service life of optical fiber distribution frame, guide rail and guide groove 121a can also be arranged in box 1 and on tray 2, the smoothness of tray 2 is improved, unnecessary friction is reduced, and the service life of optical fiber distribution frame is improved. It should be noted that the positions of guide rail and guide groove 121a can be exchanged without affecting the guiding effect of pulling tray 2, and guide rail and guide groove 121a can also be replaced by slider and sliding groove, slide rod and slider and other structures with guiding effect.

[0044] The tray 2 is provided with an L-shaped protective cover 21 at one end of the box 1 exposed to the outside, which can be detachably connected or hinged to the tray 2 for facilitating wiring.

[0050] Further, in an embodiment of the present application, the side of the first guide rail 221 facing the first guide groove 11a is provided with a clamping protrusion 2211, the first opening 1a is provided with a locking mechanism 12, the locking mechanism 12 comprises a guide seat 121, a movable block 122 and an elastic member 123, the guide seat 121 is connected with the box 1 and in sliding connection with the movable block 122, the elastic member 123 connects the movable block 122 with the box 1, the elastic member 123 drives the movable block 122 to slide along the guide seat 121, so that the movable block 122 protrudes from the inner wall of the first guide groove 11a, and the clamping protrusion 2211 is limited between the movable block 122 and the side wall of the first guide groove 11a away from the first opening 1a.

[0051] Please refer to Figure 5 、 Figure 7 、 Figure 13 and Figure 14In the embodiment, a preferred scheme of the left-right pressing type locking mechanism 12 is provided. The guide seat 121 is fixed to the top wall and the bottom wall of the box body 1 by bolt connection, and the guide seat 121 is provided with a guide groove 121a, which is arranged along the direction from the left side wall to the right side wall of the box body 1. The movable block 122 is provided with a guide block 1221 matched with the guide groove 121a, and the guide block 1221 is accommodated in the guide groove 121a and is in sliding connection with the inner wall of the guide groove 121a. In order to strengthen the connection between the inner wall of the guide groove 121a and the guide block 1221 and prevent the guide block 1221 from being separated from the guide groove 121a at the slot, the guide groove 121a can be gradually tapered along the direction from the groove bottom to the slot opening, and the guide block 1221 is correspondingly arranged to be gradually expanded along the direction away from the movable block 122. After the guide block 1221 is inserted into the guide groove 121a from the opening end of the guide groove 121a, the guide block 1221 can only slide along the guide groove 121a and cannot be separated from the guide groove 121a at the slot. The movable block 122 is further provided with a handle for the user to hold, and the end surface of the movable block 122 away from the side wall of the box body 1 is provided with a through groove matched with the first guide groove 11a. When the handle is pressed to push the movable block 122 towards the side wall of the box body 1, the through groove can be aligned with the first guide groove 11a, and at this time, the first guide rail 221 and the clamping protrusion 2211 can slide into the first guide groove 11a along the through groove. The side of the movable block 122 towards the side wall of the box body 1 is provided with a blind hole 122a, and the elastic member 123 is a spring. One end of the spring extends into the blind hole 122a and abuts against the bottom of the hole, and the other end of the spring abuts against the side wall of the box body 1. When the handle is released, the spring drives the movable block 122 to slide along the guide groove 121a and dislocate the through groove from the first guide groove 11a. The bottom wall of the through groove protrudes from the bottom wall of the first guide groove 11a, so that the clamping protrusion 2211 can be limited in the first guide groove 11a. When the functional module panel 3 is installed on the tray 2, the clamping protrusion 2211 provided on the side of the first guide rail 221 towards the first guide groove 11a, so that there is a certain gap between the first guide rail 221 and the groove bottom of the first guide groove 11a. This gap makes the movable block 122 unable to contact the guide rail, but the movable block 122 can limit the clamping protrusion 2211 in the first guide groove 11a, and the clamping protrusion 2211 can slide along the first guide groove 11a, but cannot be separated from the first guide groove 11a due to the limitation of the clamping protrusion 2211. Therefore, the tray 2 cannot be completely pulled out of the box body 1. The clamping protrusion 2211 can be arranged at the end of the first guide rail 221 away from the protective cover 21. In this way, the tray 2 can be partially pulled out until the movable block 122 in the locking assembly abuts against the clamping protrusion 2211, thereby locking the tray 2 and preventing the tray 2 from being directly dropped due to excessive pulling.

[0052] Please refer to Figure 4 , Figure 11 and Figure 12, next will provide a preferred solution of the up and down pressing type locking mechanism 12.

Among them, the guide block 1221 and the guide groove 121a can be referred to the previous scheme. The movable block 122 is also provided with a handle for the user to hold, and the end surface of the movable block 122 away from the side wall of the box body 1 is provided with a through groove matched with the first guide groove 11a. Pressing the handle pushes the movable block 122 towards the bottom wall of the box body 1, so that the through groove is aligned with the first guide groove 11a, and at this time the first guide rail 221 and the clamping convex 2211 can slide into the first guide groove 11a. The side of the movable block 122 towards the bottom plate 13 of the box body 1 is provided with a blind hole 122a, and the elastic element 123 adopts a spring, one end of the spring extends into the blind hole 122a and abuts against the hole bottom, and the other end of the spring abuts against the bottom plate 13 of the box body 1. Loosen the handle, the spring drives the movable block 122 to slide along the guide groove 121a and makes the through groove dislocate with the first guide groove 11a, and the side wall of the through groove protrudes from the side wall of the first guide groove 11a, so that the clamping convex 2211 can be limited in the first guide groove 11a. When the functional module panel 3 is installed on the tray 2, the clamping convex 2211 provided on the side of the first guide rail 221 towards the bottom plate 13 of the box body 1, so there is a certain gap between the side wall of the first guide rail 221 and the side wall of the first guide groove 11a, which makes the movable block 122 unable to contact the guide rail, but the movable block 122 can limit the clamping convex 2211 in the first guide groove 11a, and the clamping convex 2211 can slide along the first guide groove 11a, but it cannot be separated from the first guide groove 11a due to the limitation of the clamping convex 2211, so the tray 2 cannot be completely pulled out of the box body 1. The clamping convex 2211 can be arranged at the end of the first guide rail 221 away from the protective cover 21, so that the tray 2 can be partially pulled out until the movable block 122 in the locking assembly abuts against the clamping convex 2211, realizing locking the tray 2 to prevent the tray 2 from being pulled out too much and directly falling off.

[0053] It should be noted that the spring can be replaced by a spring sheet or elastic rubber, and the spring can also be replaced by a tension spring. It should be noted that when a tension spring is used, the pressing direction of the movable block 122 is opposite to that when a spring is used. In the up and down pressing type locking mechanism 12, the spring can also be arranged to connect the top cover of the box body 1 and the movable block 122.
