Detailed description of the invention
It is clearly understood to make present disclosure be easier to, below according to specific embodiment and combine accompanying drawing, the present invention is made into one
Step detailed description.
The screw of a kind of band pad, including screw body 1 and the pad 2 that is located on screw body 1, described screw body 1 includes
The cap nut 11 arranged in integrative-structure and lead screw 12, be connected with connecting rod 13 between described cap nut 11 and lead screw 12,
Described connecting rod 13 external diameter is less than lead screw 12 external diameter, and described pad 2 is provided with for the installation that pad 2 is arranged in connecting rod 13 being led to
Hole 21, described lead screw 12 is provided with convex tooth 121 relative to one end of connecting rod 13, and described convex tooth 121 is convexly equipped in lead screw 12 peripheral side
Wall, the tooth peak external diameter of described convex tooth 121 is more than installing through hole 21 internal diameter, and described lead screw 12 depends on along convex tooth 121 to the direction of the other end
Secondary including the first thread segment the 122, second thread segment 123 and the 3rd thread segment 124, the pitch of described first thread segment 122 is more than the
The pitch of two thread segments 123, the pitch of described second thread segment 123 is more than the pitch of the 3rd thread segment 124.Lead screw 12 includes many
Individual thread segment, and the pitch of each thread segment is sequentially overlapped, therefore screw is the most stubborn more tight in installation process, adds screw when fastening
Coupling mechanism force, and this screw is accompanied with pad 2, further increases steadiness when fastened by screw connects, makes screw be not likely to produce pine
Dynamic.And this pad 2 is after screw body 1 machines, pad 2 is arranged in connecting rod 13 by installing through hole 21, then
Processing lead screw 12 is relative to one end of connecting rod 13 so that it is extrusion becomes convex dental structure, and the tooth peak external diameter of the most convex tooth 121 is big
In installing through hole 21 internal diameter, making pad 2 difficult drop-off, therefore the step manually wearing pad 2 reduced or remitted by finished product screw, i.e. decreases work
The workload of personnel, also makes installation effectiveness higher.
1.1 times that pitch is the 3rd thread segment 124 pitch of described second thread segment 123, the pitch of described first thread segment 122 is
1.2 times of three thread segment 124 pitch.By lot of experimental data gained, the pitch of the second thread segment 123 is the 3rd thread segment 124 pitch
1.1 times, and 1.2 times that the pitch of the first thread segment 122 is the 3rd thread segment 124 pitch, belong to optimal test data, due to respectively
The pitch difference of thread segment is excessive, can cause and tighten difficulty, finally cannot correctly install and put in place, and the pitch difference of each thread segment is too small, the most not
Can increase the effect of coupling mechanism force, therefore the pitch of the second thread segment 123 is 1.1 times of the 3rd thread segment 124 pitch, and the first screw thread
1.2 times that pitch is the 3rd thread segment 124 pitch of section 122, for preferred plan.
Described pad 2 be in the shape of the letter V structure arrange, this pad 2 opening towards lead screw 12 side, described installation through hole 21 ovalize
Structure is arranged, and the short diameter of this installation through hole 21 is suitable with connecting rod 13 external diameter, and the short diameter of described installation through hole 21 is less than lead screw
12 external diameters.After pad 2 is arranged in connecting rod 13 by installation through hole 21, by the way of using punching press pad 2, pad 2 is processed system
Make the structure that is in the shape of the letter V, original circular mounting through hole 21 is stamped along with pad 2 simultaneously and forms ellipsoidal structure, make installation lead to
The short diameter in hole 21 is suitable with connecting rod 13, and the short diameter simultaneously installing through hole 21 is less than lead screw 12 external diameter, and has convex tooth 121
Spacing, coming off of pad 2 can be prevented further.And the pad 2 that the structure that is in the shape of the letter V is arranged has elastic force upwards after mounting,
Can further improve the stable connection of screw.The shape of pad 2 can be ellipse, circle, rectangle etc. simultaneously, as the present invention
Good preferred version, pad 2 be shaped as rectangle, two seamed edges of rectangular washer 2 are conducive to the steadiness improving pad 2 when installing.
Described pad 2 is provided with the groove 22 for housing cap nut 11 at the crest relative to cap nut 11 side.Groove 22 makes screw
Conveniently good, firm clamping origin of force is provided for cap nut 11, it is to avoid cap nut 11 swings at crest when fastening when fastening,
Affect final stable connection.
Described pad 2 is provided with reinforcement 23.Reinforcement 23 enhances the rigidity of pad 2 so that it is be unlikely to deform damage, extends pad
The service life of 2.
It is emphasized that: be the most only presently preferred embodiments of the present invention, not the present invention is made any pro forma restriction, every
Any simple modification, equivalent variations and the modification made above example according to the technical spirit of the present invention, all still falls within the technology of the present invention
In the range of scheme.
