Description

The mechanical quick-connect machanism of rod iron and nonprestressed reinforcement

Technical field

The utility model relates to a kind of bindiny mechanism, the mechanical quick-connect machanism of especially a kind of rod iron and nonprestressed reinforcement.

Background technology

Present stage, when the connection of rod iron and nonprestressed reinforcement, usual electric welding, when running into this kind of situation on-site, need the equipment such as electric welding machine, power line, its complex procedures, use inconvenience, especially when work high above the ground, pull and draw the equipment such as power cable and electric welding machine inconvenient especially, due to the restriction of building site ambient conditions, power line often can not reach instructions for use, to building site construction cause inconvenience, operating efficiency is low, waste time and energy, so provide the mechanical fast joint structure of a kind of rod iron and nonprestressed reinforcement very necessary.

Summary of the invention

In order to overcome traditional rod iron and nonprestressed reinforcement method of attachment complex procedures, need by electric welding, inefficiency, the problem that wastes time and energy, the utility model provides the mechanical quick-connect machanism of a kind of rod iron and nonprestressed reinforcement, this mechanism does not need with electric welding, structure is simple, esy to use, safe and reliable, very simple and efficient, substantially increase operating efficiency.

The utility model solves the technical scheme that its technical problem adopts: the mechanical quick-connect machanism of a kind of rod iron and nonprestressed reinforcement, comprising: non-prestressed heading reinforcing bar, locking sleeve, tapering lock dog, rod iron; There is a locking sleeve in this mechanism, described locking sleeve external diameter is cylindric, there is one insulating course locking sleeve bosom position, and the side of insulating course is one section of blind hole in axial isometrical threaded structure, and this helicitic texture mates identical with the external screw thread of non-prestressed heading reinforcing bar; The opposite side of insulating course is one section of space in tapering shape, in the space of tapering shape, coupling is equipped with the tapering lock dog that can slide up and down, and on the end face of tapering lock dog, coupling is provided with disc collar dish, its collar dish is circumferentially with the groove being inserted in turn, and in groove, coupling is set with spring; Described tapering lock dog is axially divided into 2 to 6 pieces, with teeth structure on its interior bone face, in the periphery of tapering lock dog, be respectively equipped with the groove of through annular, flexible lasso is set with in groove, it can flexible for tapering lock dog boundling together, and enable it firmly fix rod iron; Non-prestressed heading reinforcing bar is made to be connected more fastening with rod iron.

The external diameter of described locking sleeve structure or to make half be isometrical shape, second half is tapering shape, and the advantage done like this is more convenient for inserting in square pile end of body blind hole, and operation is more convenient.

During use, rod iron is inserted in locking sleeve, non-prestressed heading reinforcing bar screws in the blind hole of locking sleeve, rod iron will stop rod iron to returning play due to the effect of the occlusion teeth of tapering lock dog inside, tightly rod iron can be bitten fixing, when spring can make tapering lock dog move to reverse elasticity, band stops the elastic force returning reset, thus non-prestressed heading reinforcing bar and rod iron have been connected into an entirety.

The beneficial effects of the utility model are: the mechanical quick-connect machanism of this rod iron and nonprestressed reinforcement, and this mechanism does not need electric welding, and structure is simple, esy to use, safe and reliable, very simple and efficient, substantially increases operating efficiency.

Detailed description of the invention

In FIG, the mechanical quick-connect machanism of a kind of rod iron and nonprestressed reinforcement, comprising: non-prestressed heading reinforcing bar 1, locking sleeve 2, tapering lock dog 3, rod iron 4; There is a locking sleeve 2 in this mechanism, described locking sleeve 2 external diameter is cylindric, there is one insulating course locking sleeve 2 bosom position, and the side of insulating course is one section of blind hole in axial isometrical threaded structure, and this helicitic texture mates identical with the external screw thread of non-prestressed heading reinforcing bar 1; The opposite side of insulating course is one section of space in tapering shape, in the space of tapering shape, coupling is equipped with the tapering lock dog 3 that can slide up and down, on the end face of tapering lock dog 3, coupling is provided with disc collar dish, its collar dish is circumferentially with the groove being inserted in turn, and in groove, coupling is set with spring; Described tapering lock dog 3 is axially divided into 2 to 6 pieces, with teeth structure on its interior bone face, in the periphery of tapering lock dog 3, be respectively equipped with the groove of through annular, flexible lasso is set with in groove, it can flexible for tapering lock dog 3 boundling together, and enable it firmly fix rod iron 4; Non-prestressed heading reinforcing bar 1 is made to be connected more fastening with rod iron 4.

In fig. 2, the external diameter of this locking sleeve 2 structure or to make half be isometrical shape, second half is tapering shape, and the advantage done like this is more convenient for inserting in square pile end of body blind hole, and operation is more convenient.

During use, rod iron 4 is inserted in locking sleeve 2, non-prestressed heading reinforcing bar 1 screws in the blind hole of locking sleeve 2, rod iron 4 will stop rod iron 4 to returning play due to the effect of the occlusion teeth of tapering lock dog 3 inside, can tightly rod iron 4 be bitten fixing, when spring can make tapering lock dog 3 move to reverse elasticity, band stops the elastic force returning reset, thus non-prestressed heading reinforcing bar 1 has been connected into an entirety with rod iron 4.
