Description

Locking connection member

The utility model belongs to the connector between a kind of pin trick rod member, particularly in a kind of locking type connector with auto-lock function.

Connector between the scaffold rod member has various ways, but its switching performance is all not ideal enough, column--stull connector as disclosed early removing system in No. 92229717.7 utility model patent, its shortcoming is that its column and being connected of stull are to lean on the connector neck of cross bar to be stuck in the breach of the card bowl on the column, connector and column are not directly held tightly, in case card bowl upward breach distortion under being repeatedly used take place to become flexible, thereby it is stable that shelf is lost.Disclosed wedging type connector in No. 94205594.2 utility model patent for another example, its shortcoming is not opening of card bowl, stull is connected with column can not be directed, general scaffold mostly is quadrangle, particularly scaffold is when supporting the time spent, and shelf not just is not difficult to lay template, template is dropped easily, and have an accident.

The purpose of this utility model is to overcome the shortcoming of existing connector, proposes a kind of locking type connector.

The technical scheme of locking type connector of the present utility model is: it mainly is made of card bowl, connector, cross bar, column and clip, it is characterized in that described card bowl is fixed on the column, along uniform four breach of its perpendicular wall, this breach is in echelon wide at the top and narrow at the bottom, and the inwall of its perpendicular wall is domatic; Described connector is installed in crossbar end, and a buckle is arranged in the end of connector, its neck passes the breach of card bowl, buckle just can insert in the cavity between perpendicular wall of card bowl and column external surface, and the interior domatic contacted surface of the perpendicular wall of buckle and card bowl also be one with the perpendicular wall of card bowl in domatic equal angular domatic, form self-locking with column.It is wide at the top and narrow at the bottom similar to card bowl breach trapezoidal that the neck of described connector is, but its undersized trapezoidal in card bowl breach makes the unlikely generation self-locking of buckle.Perpendicular wall inboard between the described card bowl breach is provided with ribs.Described connector that is installed in crossbar end and cross bar be combined into fixed or rotary type.On the column above the card bowl, be welded with alignment pin.Described clip end face is provided with helicoid, the heart is porose therein, by this hole with hoop sleeve on column, at its underpart internal face one conical surface is arranged, its angle is consistent with the gradient of buckle upper end, and described clip also has a bead, one groove is arranged in this bead, can pass the alignment pin that is welded on the column, the helicoid of its upper end is contacted with the lower surface of alignment pin, and form self-locking.The bottom of described card bowl offers through hole.

The assemble method of locking type connector of the present utility model is earlier notched card bowl to be welded on the column, make the breach alignment, the cross bar that again two ends is equipped with connector is connected with column, buckle neck on the connector inserts in the breach of card bowl at this moment, the inclined-plane connects airtight mutually with the appearance inclined-plane of buckle in the perpendicular wall of card bowl, and constitute from the locking angle between the column axis, make cross bar hold column by buckle.Breach on the card bowl is more slightly larger than the neck of connector, to guarantee pinning column and cross bar by above-mentioned from the locking angle.On the perpendicular wall inner surface of card bowl,, promptly between two breach, be provided with ribs,, guarantee self-locking to strengthen card bowl strength and stiffness with breach place at 45.Do not constitute at scaffold under the situation of square or rectangle, the connector of cross bar can be made being connected of horizontally rotating with crossbar end, so that when making cross bar and column nonopiate, the connector of cross bar still can insert in the breach of card bowl.

The advantage of locking type connector of the present utility model mainly contains: the connector by the multiple self-locking of this energy can make column and being connected of cross bar stable, firm, guarantees the Founder of scaffold again; The strengthened enhancing of rib of card bowl, at the helicoid of clip end face and be welded in self-locking between alignment pin on the column, guarantee that scaffold can not become flexible and come off when lifting promotes, and under the card bowl, reserve perforation, can dispose the cement slurry that drops in the card bowl etc. easily.

In order to further specify the structure of locking type connector of the present utility model, also specifically describe in conjunction with the embodiments with reference to accompanying drawing.Its accompanying drawing has:
