The utility model content
The utility model aims to provide a kind of quick mounting or dismounting steel tube scaffold clasp, and it is simple in structure, and mounting or dismounting connect reliably easily and fast, and use and overhead cost are low.
The technical solution of the utility model is: a kind of quick mounting or dismounting steel tube scaffold clasp, comprise right-angle coupler, and to clasp, described fastener comprises fastener body and wedge block, has slot on the fastener body, wedge block is arranged in slot.
Described to clasp, its fastener body is the sleeve body, and its endoporus one side of something is the face of cylinder, and relative second half is taper seat, and its slot is opened on the wall at taper seat place; Its wedge block simultaneously is the face of cylinder, and another side is a taper seat, and taper seat something or somebody to fall back on position is equipped with a boss, and boss can move in the slot of fastener body; The steel pipe radius that the face of cylinder radius of fastener body and wedge block is connected with it is identical, and the taper seat of fastener body and wedge block is suitable.
Described right-angle coupler, its fastener body is a U-shaped card body, its bottom is the internal diameter face of cylinder identical with its steel pipe that is connected, it is hook-shaped that two tip extension are circular arc, and hook is parallel with the face of cylinder, bottom axis, and the inner surface of hook is the radius face of cylinder identical with its steel pipe that is connected, its axis and the face of cylinder, U-shaped card body bottom axis are perpendicular, its slot is opened in U-shaped card body two sides, for to the perforation, its wedge block can insert on the U-shaped card body to the perforation in.
Described fastener sleeve body and U-shaped card body and wedge block material are can rolling anti-Hou Gang.
Further, described fastener sleeve body and U-shaped card body and wedging block are cellular reinforced structure, promptly are made of honeycomb structure and reinforcing rib, but can guarantee the weight reduction again of enough intensity, economical with materials.
The utility model is simple in structure, and each fastener is two component only, and component are few, are easy to reduce manufacturing process, cut down finished cost; Mounting or dismounting can improve about 10 times of work efficiency easily and fast during use; Connect after the wedging reliably, use and overhead cost are low.
Description of drawings
Fig. 1 is the right-angle coupler connection diagram.
Fig. 2 connects generalized section for right-angle coupler.
Fig. 3 is to the clasp connection diagram.
Among the figure: 1-fastener body, 2-wedge block, 3-slot, 4-steel pipe, 5-steel pipe.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1,2 is depicted as right-angle coupler, fastener body 1 is a U-shaped card body, fastener body 1 bottom is internal diameter and its identical face of cylinder of steel pipe that is connected 4 external diameters, it is hook-shaped that two tip extension are circular arc, plane, hook place is parallel with the face of cylinder, bottom axis, the inner surface of hook is radius and its identical face of cylinder of steel pipe that is connected 5 external diameters, its axis and the face of cylinder, U-shaped card bottom axis are perpendicular, have slot 3 on the fastener body 1, slot 3 is opened in U-shaped card two sides, for to the perforation, wedge block 2 can insert on the U-shaped card body to the perforation in.
During use, the U-shaped card body face of cylinder, bottom and steel pipe 4 external surfaces is good fit, and another root steel pipe 5 places the gib head face of cylinder of U-shaped card, inserts wedge block 2, knocks wedge block 2 and just two tubes tightly can be snapped together.During dismounting, strike wedge block 2 in the other direction, just can unclamp fastener, take out steel pipe 4,5.
Figure 3 shows that to clasp fastener body 1 is the sleeve body, its endoporus one side of something is the face of cylinder, and face of cylinder radius is identical with its steel pipe that is connected 4,5, and its relative second half is a taper seat, has slot 3 on the wall at taper seat place.Wedge block 2 roughly is a watt shape, and its inner surface is the face of cylinder, and radius is identical with its steel pipe that is connected 4,5; Its external surface is a taper seat, and is suitable with the conical surface on the fastener body, and the taper seat something or somebody to fall back on position of wedge block 2 is equipped with boss, and boss can stretch out from the slot on the fastener body 13, and moves in slot 3.
