Detailed Description

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.

Example 1:

referring to fig. 1 and 2, the utility model provides a scaffold, including horizontal horizon bar 4, vertical horizon bar 5 and montant 6, there is drum 11 in the coaxial welding of one end of montant 6, and the other end welding has second stopper 7, offers the second pinhole parallel with montant 6 on second stopper 7.

Referring to fig. 4 and 5, one end of the cylinder 11 close to the vertical rod 6 is closed, a positioning rod 13 is coaxially welded in the cylinder 11, and one end of the positioning rod 13 extends out of the cylinder 11. The cylinder opening of one end, away from the vertical rod, of the cylinder 11 is provided with a first limiting block 12 extending inwards, the first limiting block 12 is provided with a first pin hole matched with the second pin hole, a thickness distance larger than the second limiting block 7 is reserved between the first limiting block 12 and the closed end of the cylinder 11, the size of the avoiding part in the middle of the two first limiting blocks 12 is larger than the size of the second limiting block 7, and the first limiting block 12 is used for limiting the second limiting block 7 to move out of the cylinder 11. When the scaffold needs to be heightened, one end of one vertical rod 6 of the scaffold with the second limiting block 7 penetrates between two first limiting blocks 12 and is inserted into a cylinder 11 of the lower-layer vertical rod 6, the vertical rod 6 is rotated, the second limiting block 7 is positioned on the lower side of the first limiting block 12, the first limiting block 12 limits the second limiting block 7 to move out of the cylinder 11, the first pin hole is aligned with the second pin hole, and then the pin is inserted into the first pin hole and the second pin hole, so that the axial rotation limiting of the two vertical rods 6 can be realized. When two montants 6 dock, can make two montants 6 dock more easily through location and the direction of location stick 13, compare the bolted connection of traditional fastener simple swift, and in the aspect of bearing, also need be more firm than the frictional force between the fastener of traditional scaffold frame and montant 6.

Referring to fig. 3, four horizontal fasteners 2 are welded on a vertical rod 6 of the scaffold, the horizontal fasteners 2 are located on the lower side of the cylinder 11, each horizontal fastener 2 comprises a fixing block 21, and a semicircular groove is formed in one side surface of the fixing block 21, which deviates from the vertical rod 6. The four fixing blocks 21 are divided into two pairs, and the two fixing blocks 21 of each pair are symmetrically arranged about the vertical rod 6. The groove openings of one pair of fixing blocks 21 face the horizontal longitudinal direction, and the groove openings of the other pair of fixing blocks 21 face the horizontal transverse direction at the lower sides thereof. A semicircular first snap ring 22 is arranged on the fixed block 21 and faces the groove, one end of the first snap ring 22 is connected with the fixed block 21 through a bolt, the other end of the first snap ring 22 is connected with the fixed block 21 in a rotating mode, and the first snap ring 22 can rotate 180 degrees in the direction away from the groove. Through first buckle 22 and the cooperation of fixed block 21, can realize pressing from both sides tightly the horizontal support pole, again because fixed block 21 welds on montant 6, so horizontal support pole can be connected on montant 6 to only need the fastening once can be connected the bracing piece with montant 6, compare traditional fastener and connect and can save a lot of work load, need not carry a large amount of fasteners and carry out work at the installer moreover, like this can be very big promotion installation effectiveness. Through setting up the opening direction of four fixed block 21 recesses to satisfy the connection of montant 6 with horizontal pole 4 and vertical horizontal pole 5.

To sum up, this embodiment is spacing through the cooperation of first stopper 12, second stopper 7 and pin, realizes connecting two montants 6 of scaffold, compares the fastener of traditional scaffold and connects more simply swiftly. Through fixed block 21 and montant 6 welding, only need fasten once can be connected together when can making montant 6 be connected with other bracing pieces, the problem that fastener fastening work load is big when having solved the scaffold installation. Because all connecting devices are directly connected to the vertical rods 6, installation personnel do not need to carry a large number of fasteners during installation, and installation work of the scaffold is facilitated.

Example 2:

referring to fig. 6, a cylinder 11 is coaxially welded to one end of a vertical rod 6, and a second stopper 7 is welded to the other end. The inner wall of the cylinder 11 and the side wall of the second limiting block 7 are provided with inner threads and outer threads which are matched with each other. One end of the cylinder 11, which is connected with the vertical rod 6, is closed, a first pin hole is formed in the closed end of the cylinder 11, and a second pin hole matched with the first pin hole is formed in the second limiting block 7. When the scaffold needs to be heightened, one end of one vertical rod 6 with the second limiting block 7 is connected into the cylinder 11 of the other vertical rod in a threaded mode, the first pin hole and the second pin hole are aligned while the scaffold is screwed, and then the pin is inserted into the first pin hole and the second pin hole, so that the limitation on the axial rotation of the two vertical rods 6 can be achieved. This embodiment is the same as the horizontal rod connection method in embodiment 1, and will not be described herein.

To sum up, this example realizes connecting two montants 6 of scaffold frame through threaded connection and pin cooperation, also connects more simply swiftly than the fastener of traditional scaffold frame.
