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), adopt hinged mode to be connected at column usually with the junction between the crossbeam (or handrail facial canal), can adapt to various stair through 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) realize through 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), and 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, cost of manufacture is high; Bonding strength is low, and is fragile.
Summary of the invention
The technical problem that the present invention will solve is the deficiency that overcomes 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 adopts following technical scheme:
A kind of stair railing oblique angle connection fittings; Comprise sleeve-like accessory body; Said accessory body one side is provided with and is used to connect fixing base; Said accessory body opposite side offers the socket that is used for column and connection fittings flexible connection, and the angle on said base plane, place and plane, said socket place is α, 20 °≤α≤50 °.
Be provided with the connector that can supply to insert from said socket in the said accessory body around empty avoiding space that tie point verts.
The base of said accessory body is provided with the connecting portion that extends to the accessory body interior.
The base of said accessory body is arranged with waterproof gland cover outward.
The socket of said accessory body is arranged with waterproof grommet.
Said waterproof grommet both sides are provided with the journal stirrup that extends to the accessory body interior, and said journal stirrup is connected fixing with the accessory body.
The span of said angle is 30 °≤α≤40 °.
Compared with prior art, the invention has the advantages that:
The accessory body that stair railing of the present invention oblique angle connection fittings have sleeve-like, accessory body one side is a base, opposite side is a socket; It is simple and compact for structure, and volume is little, occupy little space, and makes that the overall structure style of stair railing is unified more, coordinates; 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.Be provided with the connector that can supply to insert from socket in the accessory body around the empty avoiding space that tie point verts, this empty avoiding space is that connector provides bigger verting to regulate the 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 are by arbitrarily dismounting.Waterproof gland cover can prevent that sealing gets 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 is connected fixing with the accessory body, can prevent that waterproof grommet from getting loose, and guarantees that it has reliable waterproof effect.
