A kind of bolt, comprise with externally threaded cylindrical body, described cylindrical body comprises the first screw rod and the second screw rod, one side direction sunken inside of relative the second screw rod of described the first screw rod forms tapped hole, one side of relative the first screw rod of described the second screw rod convexes with round platform, the circumferential surface of described round platform is provided with outside thread, and described round platform is threaded with tapped hole.
By adopting technique scheme, the first screw rod and the second screw rod removably connect by tapped hole and round platform, the first screw rod and the second screw rod removably connect with two parts that are threaded hole respectively, need to regulate two spacing between part time, on the one hand, can be by the threaded adjusting on part and screw rod, on the other hand, can be with the threaded adjusting of crossing on round platform and tapped hole, entire length that can adjusting bolt by round platform and tapped hole, this model utility is had applied widely, telescopic feature.
The utility model is further set to: the hole depth of described tapped hole is greater than the length of round platform.
By adopting technique scheme, can reach under the state of retract bolt entire length, the hole depth of tapped hole is greater than the length of round platform, on the one hand, saves the material of manufacturing, and reduces costs; On the other hand, round platform in tapped hole time, forms spacing and forms containing space between round platform and screw thread diapire.
The utility model is further set to: between described the first screw rod and the second screw rod, be connected with chain, a side of described chain one end first screw rod relative to round platform is fixedly connected with, and the other end is fixedly connected with the diapire of tapped hole.
By adopting technique scheme, between the first screw rod and the second screw rod, be connected with chain, on the one hand, the further entire length of Lengthened bolt, on the other hand, can connect not two parts with through hole at same straight line, in the time that the first screw rod and the second screw rod link by the assembling of round platform and tapped hole, chain leaves in and between platform and screw thread diapire, forms spacing formation containing space.
The utility model is further set to: described the first screw rod is identical with the outside thread direction on the second screw rod, the outside thread opposite direction on the outside thread on described round platform and the first screw rod.
By adopting technique scheme, the first screw rod is identical with the outside thread direction on the second screw rod, outside thread opposite direction on outside thread on round platform and the first screw rod, when screw rod and Assembly of the parts with threaded hole, the assembling between the first screw rod and the second screw rod can not be affected.
The utility model is further set to: the sidewall Quenching Treatment of described tapped hole.
By adopting technique scheme, the sidewall Quenching Treatment of tapped hole, improves intensity, hardness, toughness and wear resistance, increases its working life.
Brief description of the drawings
