Detailed Description
This embodiment is an adjustable stair protection railing, is applicable to and installs the stair at different gradients and different length.
As shown in figure 1, the adjustable stair guard rail is provided with a stand column and a guard bar, wherein a mounting seat is arranged on the stand column, and the mounting seat is fixedly arranged on the side face of a stair through bolts, so that the stand column is fixedly arranged on the stair. The upright post is connected with a plurality of parallel length-adjustable guard bars through an adjustable mechanism which can adjust the installation angle of the upright post and the guard bars. Thus, the guard bar can be adjusted to a proper inclination and length and installed on the stairs.
The length-adjustable protection rod is provided with a protection rod, a protection rod II and a locking bolt, the protection rod I is installed in a shaft hole of the protection rod II in a matched mode, the protection rod II can move in the shaft direction of the protection rod I in the protection rod hole, and the protection rod II and the protection rod I are locked in position through the locking bolt installed on a protection plate. A position of the first protection rod, which is close to the second protection rod, is provided with a hole in threaded fit with the locking bolt, and the first protection rod and the second protection rod are clamped tightly by screwing the locking bolt.
The adjustable length side guard plate is provided with a first side guard plate, a second side guard plate and a locking bolt, the first side guard plate is provided with a sliding groove in the connecting line direction of two connecting ends of the first side guard plate, and the second side guard plate is slidably arranged in the sliding groove of the first side guard plate.
Furthermore, in order to avoid the situation that the second edge protection plate falls off from the first edge protection plate when the second edge protection plate moves in the first edge protection plate, sliding rails along the sliding groove direction are arranged on two sides of the sliding groove of the first edge protection plate, and sliding blocks matched with the sliding rails of the first edge protection plate are arranged on two sides of the second edge protection plate.
As shown in fig. 3, the adjustable connecting mechanism has a connecting sleeve, a connecting rod and a lock nut, and the connecting rod and the connecting sleeve are integrally formed.
