At present, the hinge connection between the column and the beam (or armrest surface tube) is realized through a pair of plastic fittings, one of which is connected to the column, and the other is connected to the beam (or armrest surface tube), and the two plastic fittings are connected to each other. Hinged joint, its disadvantage is that the plastic parts are bulky and take up a lot of space, which seriously affects the overall appearance of the stair guardrail, and the structure of the pair of plastic parts is complex, the production cost is high, the connection strength is low, and it is easy to damage

Embodiment Construction
[0020] figure 1 It shows an embodiment of a stair guardrail bevel connection fitting of the present invention, the bevel connection fitting includes a sleeve-shaped fitting body 1, one side of the fitting body 1 is provided with a base 11 for connection and fixing, and the other side of the fitting body 1 is There is a socket 12 for the movable connection between the column 2 and the connecting accessories. The angle between the plane of the base 11 and the plane of the socket 12 is α, 20°≤α≤50°, and the optimal range of the angle α is 30° ≤α≤40°, in this embodiment, α is 35°. The stair guardrail bevel connection fittings of the present invention are simple and compact in structure, small in size and occupy less space, which makes the overall structural style of the stair guardrail more unified and coordinated; reduces the production cost and reduces the overall cost of the stair guardrail; it is convenient to use metal parts for stamping Forming can effectively improve the c...

The invention discloses a stair guardrail miter joint fitting, comprising a sleeve-shaped fitting body one side of which is provided with a base used for connection and fixation, and the other side of which is provided with a faucet used for flexible connection; the included angle of a flat surface on which the base is positioned and a flat surface on which the faucet is positioned is alpha, wherein, the alpha is more than or equal to 20 degrees and less than or equal to 50 degrees. The stair guardrail miter joint fitting has the advantages of simple and compact structure, small volume and less occupation space.
Description
technical field [0001] The invention relates to a connecting fitting for a stair guardrail, in particular to an oblique corner connecting fitting for a stair guardrail. Background technique [0002] Different stairs have different rise angles. When installing the stair guardrail, the rise angle of the stair guardrail should be equal to the rise angle of the stairs. In order to enable mass-produced columns and beams (or handrail surface tubes) On the stairs with corners, the connection between the column and the beam (or handrail surface tube) is usually connected in a hinged manner, so that the angle between the column and the beam (or handrail surface tube) can be adjusted to adapt to various stairs . At present, the hinge connection between the column and the beam (or armrest surface tube) is realized through a pair of plastic fittings, one of which is connected to the column, and the other is connected to the beam (or armrest surface tube), and the two plastic fittings a...
