[0037] The telescopic assembly 75 comprises a fixed plate 751, a U-shaped cover plate 752, a sleeve 753, a sliding column 754 and a second elastic member 755; the fixed plate 751 is arranged on the top surface of the first railing 5, the sleeve 753 is arranged on the fixed plate 751, one end of the sliding column 754 is arranged on the limiting member 74 and the other end is located in the sleeve 753, the second elastic member 755 is sleeved on the sliding column 754, one end of which is connected with the sleeve 753 and the other end is connected with the limiting member 74; the U-shaped cover plate 752 is arranged on the top surface of the first railing 5 and the limiting member 74 is slidingly arranged in the U-shaped cover plate 752. In this embodiment, the first elastic member 73 and the second elastic member 755 are springs, but of course in other implementations, the first elastic member 73 and the second elastic member 755 can also be of other structural forms, which are not limited in this embodiment.

[0038] The groove bottom of the U-shaped cover plate 752 is provided with a third avoiding opening 7521, the top of the limiting member 74 is provided with an abutting member 742 which can be a strip-shaped abutting block, the abutting member 742 is partially located in the third avoiding opening 7521, and the third avoiding opening 7521 is used to limit the maximum distance of the sliding of the limiting member 74 to the other first railing 5, so as to prevent the limiting member 74 from being taken out of the U-shaped cover plate 752.

[0039] Working principle of the self-locking mechanism 7: in the initial state, the first elastic member 73 is in the uncompressed state, the second inclined surface 722 of the trigger member 72 and the first inclined surface 741 of the limiting member 74 are in the abutting state, and the telescopic assembly 75 is in the compressed state.

[0040] During installation, the T-shaped convex strips 61 arranged on the two sides of the second railing 6 are first aligned with the second avoiding opening 712 above the first railing 5 and with the first avoiding opening 711, and then the second railing 6 is installed downward. During the process of installing the second railing 6 downward, the bottom of the T-shaped convex strip 61 abuts against the abutting portion, thereby driving the trigger member 72 to move downward, and when the trigger member 72 moves downward, the second inclined surface 722 and the first inclined surface 741 gradually come out of contact, and the first elastic member 73 changes from the uncompressed state to the compressed state. At this time, since the second inclined surface 722 and the first inclined surface 741 come out of contact, the limiting member 74 moves in the direction close to the other first railing 5 under the action of the second elastic member 755 of the telescopic assembly 75, thereby closing the second avoiding opening 712 and preventing the second railing 6 from being taken out of the sliding groove 71. And at this time, due to the action of the abutting member 742 and the third avoiding opening 7521, the limiting member 74 will not be taken out of the U-shaped cover plate 752.

[0041] When the second railing 6 is removed from the first railing 5, the second railing 6 is moved upward, so that the first elastic member 73 gradually changes from the compressed state to the uncompressed state, the trigger member 72 is moved upward under the elastic force of the first elastic member 73, so that the second inclined surface 722 abuts against the first inclined surface 741, and the limiting member 74 is moved away from the other first railing 5, so that the limiting member 74 opens the second avoiding opening 712, and at this time, the telescopic assembly 75 is in the compressed state. It can be understood that the length of the T-shaped convex strip 61 is less than or equal to the length of the trigger part 721 of the trigger member 72 from one end of the trigger member 72 provided with the second inclined surface 722, so as to ensure that when the second railing 6 is removed from the first railing 5, the limiting member 74 has opened the second avoiding opening 712.

[0042] In summary, the utility model effectively overcomes various shortcomings in the prior art and has high industrial utilization value.
