Because base is plane body and is provided with groove, plane body increases the bonding area of base and cross bar so that welding More firmly, while paint enters inside cross bar when plane body also avoid brush paint, groove increases receiving for base and vertical rod Power face, so as to increased the structural stability of scaffold.
In some embodiments, grafting block includes a pair of insert-connecting plates, and a pair of insert-connecting plate alignment are fitted and are symmetrically provided with One flange piece, each flange piece is perpendicular to corresponding insert-connecting plate and covers one end of the insert-connecting plate, and the other end of the insert-connecting plate is stretched Go out corresponding flange piece, the part that a pair of insert-connecting plates stretch out correspondence flange piece is sphenoid, and base is plane where two flange pieces Body, groove is located at the joint of two flange pieces.Thus, using a pair of insert-connecting plates welding laminating and flange, thus formed base and Grafting block, is easy to processing.
In some embodiments, each insert-connecting plate, flange piece are made by wrought iron.Thus, wrought iron is partially soft, it is easy to forge Processing, and it is easy to welding, it is to avoid the danger of weld cracking.
In some embodiments, a pair of insert-connecting plates stretch out the part of correspondence flange piece and are provided with pin-and-hole, the direction of pin-and-hole with The direction of plane body is consistent where two flange pieces.Thus, the setting of pin-and-hole, plays position-limiting action when safety pin is installed.
According to other side of the present utility model, there is provided pulley-clip scaffold, including safety pin, some cross bars And vertical rod, by safety pin connection, each vertical rod is vertically provided with plum-blossom-shape button, and each plum-blossom-shape button is uniform for each cross bar, vertical rod There is bell and spigot, each bell and spigot inserts safety pin, and the one side of base is resisted against vertical rod by groove, and the another side of base is vertical It is fixed on cross bar, sphenoid insertion bell and spigot.Thus, the structure for causing scaffold using the structure of safety pin is more stablized.
In some embodiments, grafting block includes a pair of insert-connecting plates, and a pair of insert-connecting plate alignment are fitted and are symmetrically provided with One flange piece, each flange piece is perpendicular to corresponding insert-connecting plate and covers one end of the insert-connecting plate, and the other end of the insert-connecting plate is stretched Go out corresponding flange piece, the part that a pair of insert-connecting plates stretch out correspondence flange piece is sphenoid, and base is plane where two flange pieces Body, groove is located at the joint of two flange pieces.Thus, using a pair of insert-connecting plates welding laminating and flange, thus formed base and Grafting block, is easy to processing.
In some embodiments, each insert-connecting plate, flange piece are made by wrought iron.Thus, wrought iron is partially soft, it is easy to forge Processing, and it is easy to welding, it is to avoid the danger of weld cracking.
In some embodiments, a pair of insert-connecting plates stretch out the part of correspondence flange piece and are provided with pin-and-hole, the direction of pin-and-hole with The direction of plane body is consistent where two flange pieces.Thus, the setting of pin-and-hole, plays position-limiting action when safety pin is installed.
In some embodiments, pin-and-hole insertion pin.Thus, it is to avoid safety pin is scurried out plum-blossom-shape button.
The utility model simple structure, is easy to welding, also enhances structural stability.

Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is described in further detail to the utility model.
As shown in Figure 1, 2, the safety pin includes base and grafting block, and grafting block includes a pair of insert-connecting plates 1, a pair of grafting Piece 1 welds laminating and is symmetrically provided with a flange piece 2 in alignment, and each insert-connecting plate 1, flange piece 2 are made by wrought iron.Insert for a pair The part that correspondence flange piece 2 is stretched out in contact pin 1 is provided with pin-and-hole 3, the direction one of the direction of pin-and-hole 3 and the place plane body of two flange piece 2 Cause.Each flange piece 2 is perpendicular to corresponding insert-connecting plate 1 and covers one end of the insert-connecting plate 1, and the other end of the insert-connecting plate 1 stretches out Corresponding flange piece 2, the part that a pair of insert-connecting plates 1 stretch out correspondence flange piece 2 is sphenoid 4, and base is flat where two flange piece 2 Face body, groove 5 is located at the joint of two flange pieces 2.
(wherein Fig. 3 only illustrates a vertical rod and a connection for cross bar, other vertical rods and horizontal stroke as shown in Figure 1, 2, 3 The connection of bar is omitted), the pulley-clip scaffold includes safety pin, some cross bars 6 and vertical rod 7, and each cross bar 6, vertical rod 7 are led to Safety pin connection is crossed, each vertical rod 7 is vertically provided with plum-blossom-shape button 8, and each plum-blossom-shape button 8 is evenly equipped with bell and spigot 9, each bell and spigot 9 insertion safety pins, the one side of base is resisted against vertical rod 7 by groove 5, and the another side vertical welding of base is fixed on cross bar 6, Sphenoid 4 inserts bell and spigot 9, the insertion pin connection of pin-and-hole 3.
Base is plane body and is provided with groove 5, and plane body increases the bonding area of base and cross bar 6, while wrought iron material Material is partially soft, it is easy to forging processing, and is easy to the welding of cross bar 6, it is to avoid the danger of weld cracking, also causes that welding is more firm Gu, while paint enters inside cross bar 6 when plane body also avoid brush paint, groove 5 increases the stress of base and vertical rod 7 Face, so as to increased the structural stability of pulley-clip scaffold.The insertion pin of pin-and-hole 3 prevents sphenoid 4 from the socket joint of plum-blossom-shape button 8 Mouth 9 is scurried out.
Above-described is only some implementation methods of the present utility model.For the person of ordinary skill of the art, On the premise of the utility model creation design is not departed from, various modifications and improvements can be made, these belong to this practicality New protection domain.
