Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

Example one

As shown in fig. 1, the blocking mechanism disclosed in this embodiment includes an annular joint sleeve 1 and a fixing base 2 extending outward from an outer wall of the annular joint sleeve 1, and the specific shape of the fixing base 2 is adapted to the shape of a slot 13 on a lateral surface of a rung 12 on the stair, so that the annular joint sleeve 1 can be inserted and matched with the slot 13 on the lateral surface of the rung 12 through the fixing base 2, and the annular joint sleeve 1 is connected with the rung 12 together. The outer wall of the annular joint sleeve 1 is provided with a baffle piece 3 at one side of the fixed seat 2. The barrier 3 is oriented perpendicular to the fixed base 2. The barrier 3 is preferably made of rubber, plastic or rubber-plastic. Simultaneously, the side that keeps away from annular joint cover 1 that keeps off piece 3 is the slope setting for the slope of bamboo joint ladder is supported and is leaned on when vertical wall, and the face of supporting that keeps off piece 3 that keeps off can be laminated in parallel in the wall, thereby promotes the stability of bamboo joint ladder in the use. The side surface of the barrier piece 3 far away from the annular joint sleeve 1 is provided with anti-skid grains 9, so that the anti-skid performance of the barrier piece 3 is further improved.

Example two

As shown in fig. 2 and 3, the barrier member 3 is detachably connected to the ring joint housing 1 according to the first embodiment. Specifically, the outer wall of the annular joint sleeve 1 is provided with a sliding chute 4, and the sliding chute 4 is formed by rolling the side edge extending to the outer wall of the annular joint sleeve 1; correspondingly, the side surface of the blocking piece 3 is provided with a sliding block 5 which is slidably clamped in the sliding groove 4 at a position close to the annular joint sleeve 1. A limiting member 14 is disposed at an opening of one side of the sliding slot 4 to limit the sliding position of the sliding block 5 in the sliding slot 4, so as to improve the stability of the blocking member 3 when being mounted on the ring joint housing 1.

Furthermore, the outer wall of the annular joint sleeve 1 is provided with a threaded hole 6 at the same side position of the sliding groove 4, a through hole 7 penetrates through the side surface of the blocking piece 3 far away from the annular joint sleeve 1, when the sliding block 5 slides and is clamped in the sliding groove 4 and abuts against the limiting piece 14, the threaded hole 6 and the through hole 7 are arranged oppositely, a threaded piece (not shown) is arranged in the through hole 7 in a threaded manner and screwed in the threaded hole 6, and the threaded piece is preferably a screw so as to completely lock the blocking piece 3 on the outer wall of the annular joint sleeve 1.

Now, the first embodiment and the second embodiment are combined to further explain the use principle of the blocking mechanism and the bamboo joint ladder with the blocking mechanism:

when the blocking piece 3 is installed, the annular joint sleeve 1 is firstly sleeved on the ladder tube body 10 of the bamboo joint ladder, and then the sliding block 5 on the blocking piece 3 is clamped into the sliding groove 4 of the annular joint sleeve 1 in a sliding mode until the sliding block 5 abuts against the limiting piece 14. At this time, the through hole 7 is screwed into the threaded hole 6 through the through hole 7 by the screw member passing through the through hole 7, so that the relative position between the threaded hole 6 and the through hole 7 can be effectively locked to completely lock the barrier member 3 to the ring joint housing 1, thereby completing the installation of the barrier member 3.

When the blocking piece 3 is disassembled, the threaded piece is unscrewed and taken out from the threaded hole 6 and the through hole 7 so as to release the locking of the blocking piece 3 on the annular joint sleeve 1, and then the sliding block 5 on the blocking piece 3 is moved out of the sliding groove 4, so that the blocking piece 3 can be disassembled from the annular joint sleeve 1.
