Abstract

The utility model discloses a from set screw thread balance bearing screw, it adopts self-tapping screw's theory of operation to the splint that have standard screw are the carrier, and the balance bearing screw that will be less than splint material hardness designs into head and splint screw internal diameter transition fit or movable fit's cylinder, and body is slightly less than the cylinder of splint screw external diameter, when balance bearing screw receives the compulsory precession in the splint screw, makes both form threaded connection, can adjust the balance clearance as required. The utility model discloses replace the copper product preparation with low-priced plastics, make product cost reduce, preparation simple process firmly not hard up during the regulation, no slope, indiscriminate knot phenomenon.

Description

Self-threading pendulum bearing bolt
The utility model relates to the clock cornet screw.
The clock cornet screw is the set screw of regulating the verge ring gap, the accuracy that the adjusting in this gap is related to clock and watch when walking, therefore be vital part in addition in the clock and watch structure, it is a carrier with the clamping plate that are shaped on the standard screw, screws by screw thread during assembling to reach the adjusting purpose.The screw of known technology is with copper making, and it is more to consume copper material, because other part is less, so manufacturability is relatively poor, processing cost is also high, and the while screw thread easily gets loose, easy disorderly button.
The purpose of this utility model is to overcome the defective of prior art and provides a kind of material with cheapness to replace copper material, and makes other part processing easy, and low cost of manufacture is reliable and stable, tight from the external threading cornet screw when doing to adjust arbitrarily.
Description of drawings.
Fig. 1 screws the pre-structure synoptic diagram for the utility model.
Fig. 2 screws the back structural representation for the utility model.
Be described in detail in conjunction with above-mentioned accompanying drawing embodiment.
Adopt the principle of work of self-tapping screw from external threading cornet screw (referring to Fig. 1-2), with opposite means with the pre-processed standard screw of metal carrier clamping plate (1), and the cornet screw (2) that will the regulate usefulness plastic production that is lower than clamping plate (1) material hardness, and with head be processed into clamping plate (1) standard screw in be transition fit or right cylinder movingly through matching, as the fashionable targeting part of screw threads, and the right cylinder that is slightly less than clamping plate (1) standard screw external diameter is processed in body portion.
During use, earlier screw (2) guide cylinder body is inserted in clamping plate (1) screw, then screw promptly can keep vertical substantially with the clamping plate plane automatically, force screw is screwed in screw with instrument then, reach from the external threading purpose, can adjust the screw screw-in length arbitrarily when clock and watch assemble, reach the adjusting in escapement gap, the relative position that keeps screw to cooperate with clamping plate is not loosening.
This structure is not only applicable to clock and watch, also is applicable to the less instrument of load-bearing capacity, instrument and other small-sized daily necessities and office appliance.
The utility model is compared with known technology, and it replaces copper material with cheap plastics and makes cornet screw, and product cost is reduced, manufacture craft is easy, and single injection-molded can keep the relative position of screw and clamping plate in the adjustment process, stable firmly loosening, there are not inclination, random button phenomenon.

Claims (3)

1, a kind of from the external threading cornet screw, comprise the carrier clamping plate (1) and the cornet screw (2) that are processed with the standard screw, it is characterized in that:
The head of a. described cornet screw (2) is the right cylinder that matches with clamping plate (1) standard screw internal diameter, and body portion is for being slightly less than the right cylinder of clamping plate (1) standard screw external diameter;
The material hardness of b. described cornet screw (2) is lower than the material hardness of carrier clamping plate (1).
2, as claimed in claim 1 from the external threading cornet screw, the head that it is characterized in that described cornet screw (2) for the right cylinder of carrier clamping plate (1) standard screw internal diameter transition fit.
3, as claimed in claim 1 from the external threading cornet screw, it is characterized in that the head of described cornet screw (2) is and carrier clamping plate (1) standard screw internal diameter right cylinder movingly.
