Technical field
The present invention relates to the stair railing connection fittings, relate in particular to stair railing oblique angle connection fittings.
Background technology
Different stair have different lift angles, when stair railing is installed, the lift angle of stair railing should equate with the lift angle of stair, for the column that makes batch process can be installed on the stair of the different lift angles of various tools with crossbeam (or handrail facial canal), usually adopt hinged mode to be connected at column with the junction between the crossbeam (or handrail facial canal), can adapt to various stair by the angle of regulating between column and the crossbeam (or handrail facial canal) like this.At present, the hinged of column and crossbeam (or handrail facial canal) realized by a pair of plastic fittings, this in the plastic fittings one be connected with column, another part is connected with crossbeam (or handrail facial canal), two plastic fittingss are hinged, its defective be the plastic fittings volume big, take up room big, have a strong impact on the overall appearance of stair railing, and this is to the plastic fittings complex structure, the cost of manufacture height, bonding strength is low, and is fragile.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, provide a kind of simple and compact for structure, volume is little, the stair railing oblique angle connection fittings that occupy little space.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of stair railing oblique angle connection fittings, comprise cover tubular accessory body, described accessory body one side is provided with the base that is used to be connected and fixed, described accessory body opposite side offers the socket that is used to flexibly connect, the angle on plane, described base place and plane, described socket place is α, 20 °≤α≤50 °.
Being provided with in the described accessory body can be for the connector that inserts from described socket around empty avoiding space that tie point verts.
The base of described accessory body is provided with the connecting portion that extends to the accessory body interior.
The base of described accessory body is arranged with waterproof gland cover outward.
The socket of described accessory body is arranged with waterproof grommet.
Described waterproof grommet both sides are provided with the journal stirrup that extends to the accessory body interior, and described journal stirrup and accessory body are connected and fixed.
The span of described angle α is 30 °≤α≤40 °.
Compared with prior art, the invention has the advantages that:
Stair railing of the present invention oblique angle connection fittings have the accessory body of cover tubular, accessory body one side is a base, and opposite side is a socket, and it is simple and compact for structure, volume is little, occupy little space, make the overall structure style of stair railing unified more, coordinate, and reduced cost of manufacture, reduced the whole cost of stair railing, simultaneously, be convenient to adopt extrustion of metals to be shaped, can effectively improve bonding strength, strengthen the safety of stair railing.Being provided with in the accessory body can be for the connector that inserts from socket around the empty avoiding space that tie point verts, and the space is regulated for connector provides bigger verting in this empty avoiding space, makes the angle adjustable range increase, and adaptive capacity is stronger.The base of accessory body is provided with the connecting portion that extends to the accessory body interior, and its safety is stronger, after socket inserts connector, just securing member is blocked, and can prevent that connection fittings from arbitrarily being dismantled.Waterproof gland cover can prevent that sealing enters between base and handrail facial canal, prevent securing member and the corrosion of accessory body, guarantees its connection reliability.The socket of accessory body is arranged with waterproof grommet, and the waterproof grommet both sides are provided with the journal stirrup that extends to the accessory body interior, and journal stirrup and accessory body are connected and fixed, and can prevent that waterproof grommet from getting loose, and guarantee that it has reliable waterproof effect.
