Abstract

A threaded connection combination, comprising a first workpiece, a second workpiece and a threaded connection member. The first workpiece is provided with a mounting hole penetrating opposite surfaces of the first workpiece. The second workpiece is provided with a screwed hole. The screwed hole comprises a first interconnecting piece with a larger diameter, and the first interconnecting piece penetrates a surface of the second workpiece. The screwed hole also comprises a second interconnecting piece with a smaller diameter. The second interconnecting piece interpenetrates the first interconnecting piece. The threaded connection member comprises a first screw and a second screw. The first screw is provided with a through hole along the axial direction. The first screw passes through the mounting hole of the first workpiece and is screwed on the first interconnecting piece of the screwed hole of the second workpiece. The second screw passes through a through hole of the first screw and is screwed on the second interconnecting piece of the threaded hole of the second workpiece. Compared with the prior art, the threaded connection combination uses the second screw to pass through the first screw and is used to lock the first workpiece and the second workpiece together with the first screw, so more reliable threaded connection is realized.

Embodiment

Please refer to Fig. 1, the present invention's combination that is threaded comprises one first workpiece 10, one second workpiece 20 and is used to connect the threaded connector 30 of this first,

second workpiece

10,20.

See also Fig. 2, this first workpiece 10 is provided with the mounting hole 11 that runs through.

This second workpiece 20 is provided with a tapped hole 21.The cross section of this tapped hole 21 is " T " shape, comprise that a diameter is big and run through this second workpiece 20 upper surface first joint 211 and one with these first joint, 211 perforation and second less joints 212 of diameter.The diameter of the mounting hole 11 of the diameter of this first joint 211 and this first workpiece 10 about equally.

This threaded connector 30 comprises one first screw 31 and second screw 33.

This first screw 31 comprises the bar portion 312 that a hexagonal head 311 and is stretched from the edge, bottom surface of this head 311.The surface of this bar portion 312 forms screw thread.This first screw 31 is provided with a through hole 310 along its medial axis.This through hole 310 comprises that bigger first accommodation section 3101 and of diameter near the end face place of this head 311 is formed at the below of this first accommodation section 3101 and runs through the second less accommodation section 3102 of diameter of this bar portion 312 always.Joint in first,

second accommodation section

3101,3102 of this through hole 310 in this first screw 31 forms stopper part 3103.

This second screw 33 comprises a head 331 and the bar portion 332 of stretching from the edge, bottom surface of this head 331.This bar portion 332 forms screw thread away from an end of this head 331.The diameter of this head 331 be slightly less than this first screw 31 through hole 310 first accommodation section 3101 diameter and greater than the diameter of second accommodation section 3102 of the through hole 310 of this first screw 31.The diameter of this bar portion 332 is slightly less than the diameter of second accommodation section 3102 of the through hole 310 of this first screw 31.

Please refer to Fig. 3, need to connect this first, second workpiece at 10,20 o'clock, this first workpiece 10 is posted by the upper surface of this second workpiece 20, and make the mounting hole 11 of this first workpiece 10 align first joint 211 of the tapped hole 21 of this second workpiece 20.The mounting hole 11 of this first workpiece 10 is passed in the bar portion 312 of this first screw 31 and be screwed together in first joint 211 of tapped hole 21 of this second workpiece 20, and utilize instruments such as spanner to tighten this first screw 31.The bar portion 332 of this second screw 33 is penetrated the through hole 310 of this first screw 31 from the head 311 of this first screw 31.The end that the bar portion 332 of this second screw 33 is provided with screw thread stretch out downwards this first screw 31 through hole 310 second accommodation section 3102 and be screwed together in second joint 212 of tapped hole 21 of this second workpiece 20; Utilize instruments such as screw-driver to tighten this second screw 33, make the head 331 of this second screw 33 push against the stopper part 3103 of this first screw 31.

As stated, first workpiece 10 and second workpiece 20 because first screw 31 and second screw 33 are used to lock simultaneously, and second screw 33 pushes against first screw 31, thus make screw linkage structure of the present invention more reliable compared to existing technology.
