Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a railing joint and a railing. Background Art

[0002] The application document with publication number CN211285262U discloses a precision cast railing joint, including a movable mechanism and a mounting mechanism, wherein the movable mechanism is arranged in the inner cavity of the mounting mechanism; an inner cylinder is sleeved in the inner cavity of the outer cylinder, a connecting thread is arranged on the inner wall of the inner cylinder, and an anti-slip sealing ring is installed in the inner cavity of the inner cylinder, so that when connecting the railing, the length of the joint can be freely adjusted to avoid the result of connection failure due to the joint length being too short or the railing being too short. Nuts are installed on the outer wall of the mounting frame, fixing bolts are welded at the rear end of the nuts, and threaded holes are opened on the outer wall of the arc-shaped connecting block, and fixing bolts are passed through the inner cavity of the threaded holes, so that the arc-shaped connecting block can be rotated one hundred and eighty degrees in the U-shaped mounting groove and the joint can adapt to railing connections at multiple angles. Compared with traditional fixed single-angle joints, it is more flexible and more competitive.

[0003] However, although the structure of the joint can be adjusted arbitrarily to adapt to the installation of railings at various angles, it is always movable and rotated relative to each other and cannot be fixed. As a result, when installing the railing, the staff need to fix the angle with one hand and rotate the railing with the other hand for installation, which causes inconvenience, time-consuming and labor-intensive. For this reason, we propose a railing joint and a railing. Utility Model Content

At this time, the second connector 4 on the rotating member 3 can be rotated relative to the U-shaped fixing member 2 on the first connector 1. After adjusting to a suitable position, release the handle 506. Under the rebound action of the spring 504, one end of the positioning rod 501 is inserted into the corresponding positioning hole 7 for locking. At this time, insert one end of the railing to be reconnected into the second connector 4, and a stable installation can be completed. During the long-term use and replacement of the railing, if the relative rotation of the U-shaped fixing member 2 and the rotating member 3 is blocked due to rust, inject lubricating oil into the oil filling groove 601, and lubricate the rotating part through the cotton block 602.
