It is connect with cross bar tapered end, bolt is equipped with limiting slot close to the side of bolt positioning device, and stop part withstands the slot bottom of limiting slot, bullet
The decrement of spring is less than the depth of limiting slot.When scaffold is installed as a result, the disk slot of cross bar tapered end is inserted in the circle of montant
On disk, and by the hole in pin hole alignment disk, operator pulls out pin rod on the other hand, and stop part is retreated with pin rod, spring quilt
Compression, another hand-held catch top of operator presses down, and after bolt is installed in place, unclamps pin rod, limit is withstood at the top of stop part
The slot bottom of position slot；The decrement of spring is less than the depth of limiting slot, illustrates whether tower bolt does not assemble with disc hole, stop part
Top can be in limiting slot always, and definitely bolt is without departing from pin hole, bolt and cross bar tapered end integrated design, and component is not
Easily lose, whole installation process is quick, improves construction efficiency；Even if scaffold is not allowed to slip out of pin hole shaking bolt yet,
Improve security performance.
In some embodiments, locating ring is equipped with external screw thread, and cross bar tapered end is equipped with and the matched interior spiral shell of the external screw thread
Line.Locating ring and cross bar tapered end, if later stage stop part or spring wear, are convenient for the dismounting of pin rod using being threadedly coupled as a result,.
In some embodiments, the front end face of bolt is vertical plane, and the rear end face of bolt is rear angled surfaces, inclined surface
It is connected with limiting stand, limiting slot upper end initial position is higher than the position of limiting stand.Limiting stand is arranged in bolt as a result, when bolt is past
Lower pressing, if limiting stand is contradicted to cross bar plug, the installation site of bolt is arrived the limit.
In some embodiments, the upper end two sides of bolt are equipped with anti-skidding stupefied.It is applied on bolt as operator as a result,
When plus-pressure, due to bolt be equipped with it is anti-skidding stupefied, bolt is not easy to slip from operator's hand, also allow for dismounting when, the person of being conveniently operated
Extract bolt.
In some embodiments, stop part is cylinder, and the diameter of stop part is less than the width of limiting slot, stop part with
Pin rod is connected through a screw thread.Stop part is connected through a screw thread with pin rod as a result, if stop part has abrasion, is conveniently replaceable, pin rod
It can also reuse.
Compared with prior art, the utility model has the beneficial effects that：The utility model is simple in structure, by cross bar tapered end
Disk slot is inserted on the disk of montant, and by the hole in pin hole alignment disk, and operator pulls out pin rod, spring on the other hand
It is compressed, another hand-held catch top of operator presses down, and after bolt is installed in place, unclamps pin rod, is withstood at the top of stop part
The slot bottom of limiting slot, not tower bolt whether assembled with disc hole, the top of stop part can be in limiting slot always, definitely bolt
Without departing from pin hole, bolt and cross bar tapered end integrated design, component are not easy to lose, and whole installation process is quick, and raising is applied
Work efficiency rate, after the completion of assembly, even if scaffold shakes, since stop part centainly withstands limiting slot, bolt is not allowed from pin hole yet
Interior slippage improves security performance.
