Abstract

The invention relates to a fastener for fixing scaffolds and an assembling/disassembling tool. A rapidly assembled/disassembled fastener is composed of an upper-half fastener and a lower-half fastener, the upper-half fastener is in damped hinge with the lower-half fastener by rivets, and the structures of the upper-half fastener and the lower-half fastener are the same; the upper-half fastener comprises a base, a cover plate, a draw bar, a lock lever and a safety lock; the left end of the base is hinged with the left end of the cover plate, and the right end of the cover plate is provided with a U-shaped open slot; a safety-lock clamp, a washer of the safety lock and a locking bit are fixed on the upper surface of the cover plate; the washer of the safety lock is hinged with the safety lock by a pin shaft and a torsional spring; when moving anticlockwise, the safety lock can be hung by the safety-lock clamp, thereby facilitating the operation of the lock lever; the right end of the base is hinged with the lower end of the draw bar, the upper end of the draw bar is eccentrically hinged with an arc head at the lower end of the lock lever, the draw bar is embedded in the U-shaped open slot of the cover plate, and the arc head at the lower end of the lock lever is pressed on the upper right end of the cover plate; and the locking bit is provided with a stepped locked groove, and the opening of the locked groove is shielded by the safety lock. The assembling and disassembling of the fastener are time-saving and labor-saving without fearing of being exposed to the sun and rain.

Description

The fastener that loads and unloads fast

Technical field

The present invention relates to a kind of fastener of fixedly scaffold.

Background technology

The fixedly employing bolt and nut of the scaffold clasp of building trade use is at present wasted time and energy during installing/dismounting, influences the duration.Moreover fastener exposes to the sun and rain, and gets rusty easily, and brings more burden to dismounting.

Summary of the invention

In order to overcome the shortcoming of prior art, the present invention provides a kind of fastener of quick loading and unloading, and its installing/dismounting is time saving and energy saving, is not afraid of and exposes to the sun and rain.

The present invention solves the technical scheme that its technical problem takes: a kind of fastener of quick loading and unloading, to form by upper and lower half fastener, and upper and lower half fastener has damping hinged through rivet, and upper and lower half fastener structures is identical; First fastener comprises pedestal, cover plate, pull bar, locking bar and safety lock; The left end of the left end hinged closures of pedestal; The right-hand member of cover plate has U type open slot, and fixing insurance pintle hook lock, safety lock washer and locking head pass through bearing pin, the hinged safety lock of torsion spring on the cover plate upper surface on the safety lock washer; Safety lock is moved the pintle hook lock that can be insured counterclockwise and is tangled, and makes things convenient for the operation of locking bar; The lower end of the hinged pull bar of right-hand member of pedestal, the circular arc head off-centre of the upper end of pull bar and locking bar lower end is hinged, and pull bar is embedded in the U type open slot of said cover plate, and the circular arc head of locking bar lower end is pressed in the upper right side of said cover plate; Described locking head has stair-stepping locked groove, and the opening part retaining of locked groove has described safety lock.

A kind of instrument of quick loading and unloading fastener comprises outer tube, intervalve, interior boosting-rod, sleeve and depression bar, is with intervalve in the outer tube slidably; Be with interior boosting-rod in the intervalve slidably, the right-hand member of interior boosting-rod is through screw retaining pad, when boosting-rod and intervalve elongate in preventing; Slippage in the intervalve; The left end of interior boosting-rod has U type groove, and the right-hand member of U type groove setting-in sleeve, the left end of sleeve have the corresponding sleeve pipe of termination 15 cross sections with said locking bar 11; The U type groove vertical direction of boosting-rod has T type bearing pin in said, and the circular arc head off-centre of T type bearing pin and depression bar one end is hinged.

The present invention is simple in structure, and installing/dismounting is time saving and energy saving, is not afraid of and exposes to the sun and rain.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the present invention is further specified.

Fig. 1 is a front view of the present invention;

Fig. 2 is a cover plate vertical view of the present invention.

The specific embodiment

Shown in accompanying drawing, the present invention is made up of upper and lower half fastener, and upper and lower half fastener has damping hinged through rivet 1, and upper and lower half fastener structures is identical.First fastener comprises pedestal 2, cover plate 3, pull bar 13, locking bar 11 and safety lock 7; The left end of the left end hinged closures 3 of pedestal 2; The right-hand member of cover plate 3 has U type open slot 12, and fixing insurance pintle hook lock 4, safety lock washer 5 and locking head 10 pass through bearing pin, torsion spring 6 hinged safety locks 7 on cover plate 3 upper surfaces on the safety lock washer 5; Safety lock 7 is moved the pintle hook lock 4 that can be insured counterclockwise and is tangled, and makes things convenient for the operation of locking bar 11.The lower end of the hinged pull bar 13 of the right-hand member of pedestal 2, the circular arc head off-centre of the upper end of pull bar 13 and locking bar 11 lower ends is hinged, and pull bar 13 is embedded in the U type open slot 12 of said cover plate 3, and the circular arc head of locking bar 11 lower ends is pressed in the upper right side of said cover plate 3.Described locking head 10 has stair-stepping locked groove 15, and the opening part retaining of locked groove 15 has described safety lock 7.

In order to prevent locking bar 11 slippage from the cover plate 3, described cover plate 3 and the circular arc head contact position of locking bar 11 are fluted 8, and the circular arc head of locking bar 11 is embedded in the groove 8.

A kind of instrument of quick loading and unloading fastener; Comprise outer tube 22, intervalve 21, interior boosting-rod 20, sleeve 19 and depression bar 16; Be with intervalve 21 in the outer tube 22 slidably, boosting-rod 19 in being with slidably in the intervalve 21, the right-hand member of interior boosting-rod 19 is through screw 24 fixed stop pads 23; When boosting-rod 20 elongates with intervalve 21 in preventing, from intervalve 21 interior slippages.The left end of interior boosting-rod 20 has U type groove, and the right-hand member of U type groove setting-in sleeve 19, the left end of sleeve 19 have the corresponding sleeve pipe of termination 15 cross sections with said locking bar 11.The U type groove vertical direction of boosting-rod 20 has T type bearing pin 26 in said, and T type bearing pin 26 is hinged with the circular arc head off-centre of depression bar 16 1 ends.
