Abstract

The utility model relates to a quick-removable cross fastening device which alters original traditional device fastened by using a bolt and a cap nut to a device fastened by locking a cam finger and a slant. The primary members are a trunk cam finger, a cotter pin and an adjusting component on the cotter pin. The utility model assembles the entire components to an entire fastening device against the problem of easily missing components, removable difficulty and difficult recovery and utilization because of bolts rusting. The device is simple in principle, reasonable in structure, reliable and safe in work, convenient and quick in installing and dismounting, stronger in adaptability and it saves the labor and time, increases the efficiency by times, reduces largely the labor intensity and lowers the attrition. The device needs to repair with little possible.

Description

The fastening cross joint fastener of quickly dismantled

The utility model belongs to the fastening clip that builing industry is used for scaffolding.

Employedly be connected in building and maintenance industry scaffold at present, fastening clip, its fastening means is that one End rivet is hinged with two and half garden anchor ears, the other end by removing tight nut, reaches fastening purpose with a M12 bolt.Under normal circumstances, remove a tight fastener and need 1 minute.The time-consuming work efficiency of requiring great effort is low, and builing industry is open work mostly, and an engineering is finished, its cycle is at least in year, long-term wind, drenches with rain, and the cement dust and sand of work progress splashes in addition, very easily the corrosion rust is dead to cause fastener, finally is difficult to dismounting, causes recovery to use difficulty again.Reclaim used fastener, the human and material resources that spend is bigger must soak, scrub, clear up a tooth with diesel oil or gasoline earlier, assort bolt, the nut lost, coat lubricating oil again, and rotating screw cap makes it nimbly and freely back and forth, can re-use.

The purpose of this utility model is to provide a kind of principle simple, rational in infrastructure, safe and reliable for overcoming above-mentioned the deficiencies in the prior art part, easy installation and removal, and can greatly improve work efficiency, the fastening cross joint fastener of the quickly dismantled that reduces labor intensity.

The purpose that the utility model proposes is achieved in that the change fastening means, and bolt, nut fastener that former tradition is used are changed into the fastener that cam finger adds the inclined-plane locking.It comprises anchor ear and securing member thereof, it is characterized in that managing anyhow carrier 1 links to each other by guide finger 7 with the guide pad 6 that is positioned at its and arranged on left and right sides, left and

right anchor ear

2,3 and guide pad 6 flexibly connect, eccentric trunk pawl 8 is connected with left anchor ear 2 by

lateral pin

9,10 with cotter pilotage 11, transverse tube gland 13 flexibly connects with carrier 1, eccentric trunk pawl 8 is connected regulating part 14 movable being installed on the cotter pilotage 11 with carrier 1 by

lateral pin

9,10 with cotter pilotage 11.

The utility model is assembled into a whole fastener with its whole component, overcome that component are easily lost and because of the bolt rust dead, defectives such as the difficult recycling of difficult dismounting.Proper as keeping, the rate of reusing can reach 100%.By as seen above-mentioned, the utility model has the advantages that principle is simple, rational in infrastructure, safe and reliable, installing/dismounting is quick and convenient, saving of work and time, become several times to improve work efficiency, reduce labor intensity greatly, reduce the wastage and have, need not keep in repair basically than strong adaptability.

Fig. 1,2 is respectively the overlooking of the said cross joint fastener of the utility model, elevation.

Fig. 3,4 is respectively that the left side of the direct fastener relevant with the utility model is looked, vertical view.

Fig. 5 is the elevation of the universal clasp relevant with the utility model.

The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.

Referring to Fig. 1,2, manage carrier 1 anyhow and be connected by guide finger 7 with guide pad 6 and manage anyhow on the carrier 1.Left and

right anchor ear

2,3 fuses by hinge 4,5 and guide pad 6.Eccentric trunk pawl 8 links together by

lateral pin

9,10 and left anchor ear 2 with cotter pilotage 11.During work, slip off the opening on the right anchor ear 3, left and

right anchor ear

2,3 is promptly opened simultaneously, put into vertical tube after, close up left and

right anchor ear

2,3, the outside, the force side of eccentric trunk pawl 8 is a semi circular surface, its top is a plane, its eccentricity is 0-4.5mm.Add solenoid at the force side of this trunk pawl 8 cover one, make it rotate 90 °,, force left and

right anchor ear

2,3 to clamp vertical tube by the wobbler action power of trunk pawl 8.Transverse tube gland 13 fuses with carrier 1 by hinge hinge 12, opens transverse tube gland 13 and puts into transverse tube, uses the same method and rotates trunk pawl 8, can lock transverse tube.During dismounting, counter-rotation 90.Trunk pawl 8 can unclamp the pipe anyhow that is clamped immediately.Because the outside, trunk pawl 8 force sides is a semicircle, its top is the locking plane of one 10 mm wides, so outside semi circular surface makes rotation trunk pawl 8 laborsaving, self-locking and anti-skidding effect have then been got in the plane, top.In actual use, because of the vertical tube holding capacity bigger, for guaranteeing that coupling mechanism force is safe and reliable, strengthening non-skid property, on horizontal, vertical pipe carrier 1 design have one with vertical plane be 10-12 ° chute 15, guide finger 7 is housed in it, like this, guide pad 6 can move down with the suffered gravity of transverse tube with left and

right anchor ear

2,3, has got the effect that further adds wedge, locking vertical tube.Regulating part 14 is to be sleeved on adjusting pad on the cotter pilotage 11 for adapting to the pipe diameter variation.Can both guarantee to clamp by the caliber of Ф 51-Ф 48mm by increase and decrease pad, realization steel pipe, so have stronger compliance.

Referring to Fig. 3,4,5, the eccentric trunk pawl 8 of above-mentioned said main member, cotter pilotage 11 and on regulating part 14 also can be used for direct fastener and universal clasp simultaneously.
