Description
Technical field
This utility model is related to communication signal and accurate technical field of fastening, especially relates to a kind of screw and nut group
Component.
Background technology
Spiro connecting element: screw, bolt and nut etc., it has been widely used as the mode with reference to object；Especially
Occupy extremely important status always in machinery and electronics industry, and screw of the prior art and nut assembly exist
When tightening, it is better (referred to as zero point) to be often difficult to find an effectiveness comparison, often needs constantly regulate to test, just can find
Tighten position close to zero point for one, and easily due to reasons such as vibrations, leave dead-center position again；And when back-outing, due to stinging
Composition and division in a proportion tightlier leads to be difficult to back-out, or destroys screw-nut after back-outing.
Utility model content
The utility model proposes a kind of structure is simple, the screw of reusable edible and nut assembly.
The technical solution of the utility model is achieved in that
A kind of screw and nut assembly, including nut and screw, described screw includes thread screw, connecting portion, screw
Termination, has screw thread starting point in described thread screw near one end of described connecting portion, also include on described screw termination and
The a positioning block being connected with described screw thread starting point；
Described nut includes the nut inner thread that nut body is matched with described thread screw, spiral shell in described nut
There has been tooth point one end of stricture of vagina, also includes the locating piece card body being connected on described nut body and with described tooth point；
Wherein, when described thread screw is fully screwed into described nut body, described locating piece card body just contacts and blocks
Locating piece is stated in residence.
Further, described screw termination section is square and has an outside projection at four angles respectively.
Further, locating piece is the lower convexity at projection described in.
Further, described locating piece card body is at described nut inner thread.
Further, described tooth point, the central point of nut body, the central point of locating piece card body are in straight line
On.
Further, described locating piece card body is the upper projection on described nut body.
Further, described locating piece, locating piece card body material are conduction or guide-lighting ripple signal material.
Further, described locating piece, the material of locating piece card body are copper.
Further, described nut, screw material are copper.
Further, described locating piece card body is perpendicular to the upper surface of described nut body, described locating piece perpendicular to
The lower surface of described screw termination.
Employ technique scheme, the beneficial effects of the utility model are: using between screw thread starting point and a tooth point be
Signal communication is connected or is conductively connected so that nut is to match to be connected at zero point with screw, to reach threaded rail
On road, have and orientate ' zero ' function of putting as it is not necessary to find optimum efficiency value when nut is tightened with screw phase, that is,
At zero point；Simultaneously, it is to avoid screw screws in after nut naturally to bottom, causes mutual end face to connect, moment can be produced when screwing out
Become big, thus destroying screw thread assembling moment.Screw-nut two part is playing the upper end surface of tooth point position, increases limited block, keeps away
Screwless affects moment to mutual end face after screwing in nut, and (after limited block contacts with each other, nut limited block plays and blocks screw
The effect screwing in again).When back-outing screw, be also not in because nut and screw thread connect the relatively tighter or long period
Occlusion lead to twist not problem out, this molectron can recycle, and economizes on resources, cost.

Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of this utility model protection.
As Figure 1-5, a kind of screw and nut assembly, including nut and screw, described screw includes thread screw
1st, connecting portion 2, screw termination 3, has screw thread starting point 8 in described thread screw 1 near one end of described connecting portion 2, also includes setting
The a positioning block 4 being connected on described screw termination 3 and with described screw thread starting point 8；It is letter that screw thread starting point 8 is connected with locating piece 4
Signal communication is connected, or is conductively connected；
Described nut includes the nut inner thread 6 that nut body 5 is matched with described thread screw 1, in described nut
There has been tooth point 9 one end of screw thread 6, also includes the locating piece card body being connected on described nut body 5 and with described tooth point 9
