Abstract
The utility model discloses a steel tube scaffold wedging rotary fastener which is formed by riveting two hoop-type buckles via a rotary pin shaft back to back, wherein each hoop-type buckle comprises a buckle seat whose inner wall is circular and an arcuate buckle cover, one end of the buckle seat is hinged with one end of the buckle cover, and the key point is that the other end of the buckle seat is provided with an upper and a lower ears between which clearance is kept, and strip-type holes whose axial direction accords with the rotary pin shaft are arranged on the two ears, the other end of the buckle cover is a movable end on which a pin hole is arranged, when connecting pipelines, the movable end is wedged between the two ears and tightly locked with the buckle seat via a wedge which drills through the strip-type hole and the pin hole. The steel tube scaffold wedging rotary fastener has the advantages of fast and swift installation, simple structure and light weight.
Description
Technical field
The utility model relates to a kind of anchor clamps that are used to connect building pipe fitting termination, specifically, is a kind of steel pipe scaffold wedging type rotary buckle.
Background technology
In building trade construction, people adopt various fasteners to set up scaffold, relatively Chang Yong fastener right-angle coupler is arranged, to clasp and rotary buckle.Wherein, rotary buckle is used for the connection that is arbitrarily angled cross pipeline with two, Chinese patent " building steel tube scaffold cold stamping the rotary buckle " (patent No.: ZL00216397.7) disclose a kind of rotary buckle, this fastener comprises the hoop formula latch closure of two same structures that connected by rotary pin shaft, two hoop formula latch closures can rotate mutually, this hoop formula latch closure mainly is made of Button Block and buckle closure, the inwall of Button Block is a circular arc, this Button Block an end be provided with journal stirrup, one end of buckle closure is hinged on this journal stirrup, during assembling, the other end of the other end of buckle closure and Button Block is fastening with bolt.Because fastener is often beaten ground from the high-altitude, mouthful breakage easily of the silk of bolt, therefore, in use maintenance capacity is bigger, and, bolt manufacturing cost height, installation rate is also slower, has reduced the efficient of setting up scaffold.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of steel pipe scaffold wedging type rotary buckle, and this rotary fastener is fastening with Button Block and buckle closure by voussoir, has improved the efficient of setting up scaffold.
In order to address the above problem, the technical solution of the utility model is: a kind of steel pipe scaffold wedging type rotary buckle, form through the rotary pin shaft riveted by the hoop formula latch closure of two same structures is back-to-back, each hoop formula latch closure comprises a Button Block and an arc buckle closure, the inwall of Button Block is a circular arc, one end of this Button Block and an end of described buckle closure are hinged, its key is: the other end of described Button Block is provided with two ears up and down, leave the gap between two ears, and on two ears, be provided with the bar hole consistent with the axial direction of described rotary pin shaft; The other end of described buckle closure is a movable end, is provided with pin-and-hole on this movable end, and during connecting pipe, this movable end snaps in voussoir through passing bar hole and pin-and-hole and Button Block locking between two ears of Button Block.
As preferred embodiment of the present utility model, on the slotted hole wall of described one of them bar hole of Button Block, be provided with anti-slip prominent tenon, the side of described voussoir is provided with chute, and when voussoir passed bar hole and pin-and-hole, described anti-slip prominent tenon fell in the chute of voussoir; The closed at both ends of this chute.In order to increase the intensity of buckle closure, and the casting technique of improving buckle closure, reinforcing rib be provided with at the edge of described buckle closure outer wall.
Compared with prior art, the beneficial effects of the utility model are: the utility model is fastening with Button Block and buckle closure by voussoir, has improved the speed of setting up scaffold greatly, and, the voussoir low cost of manufacture, not easy to wear, need repairing hardly in the use, saved the cost of enterprise greatly.
Description of drawings
Fig. 1 is user mode figure of the present utility model;
Fig. 2 is the stereogram of Button Block 2;
Fig. 3 is the stereogram of buckle closure 1;
Fig. 4 is the stereogram of voussoir 6.
The specific embodiment
Further the utility model is illustrated below in conjunction with drawings and Examples.
Shown in Fig. 1 to 4, steel pipe scaffold wedging type rotary buckle forms through rotary pin shaft 4 riveteds by the hoop formula latch closure of two same structures is back-to-back, hoop formula latch closure mainly is made of Button Block 2 and arc buckle closure 1, the inwall of Button Block 2 is a circular arc, one end of this Button Block 2 is provided with a journal stirrup 2d, the other end is provided with two ear 2a up and down, leave the gap between two ear 2a, and on two ear 2a, be provided with the bar hole 2b consistent with the axial direction of rotary pin shaft 4, the slotted hole wall of the bar hole 2b of one of them ear 2a is provided with anti-slip prominent tenon 2c, the arcuate flanks of two Button Blocks 2 is back-to-back through rotary pin shaft 4 riveteds, makes two Button Blocks 2 to rotate mutually; As shown in Figure 3, buckle closure 1 is an arc, the upper and lower side of buckle closure 1 outer wall is provided with reinforcing rib 1b, one end of this buckle closure 1 is hinged on the journal stirrup 2a through rivet 3, one end of buckle closure 1 is a movable end, be provided with pin-and-hole 1a on this movable end, during assembling, this movable end snaps in voussoir through passing bar hole 2b and pin-and-hole 1a 6 and Button Block 2 lockings between two ear 2a of Button Block 2; As shown in Figure 4, the side of voussoir 6 is provided with chute 6a, in processing during fastener, earlier with the end opening of chute 6a, after anti-slip prominent tenon 2c falls in the chute 6a of voussoir 6, again with the openend sealing of electric welding with chute 6a, like this, voussoir 6 is played spacing effect, make voussoir 6 form whole the connection with Button Block 2, voussoir 6 can not break away from bar hole 2b, to improve the efficient that scaffold is installed.
