Abstract
The utility model discloses a fixed structure of a watch hairspring stud, which comprises a hairspring stud and a stud ring, wherein the peripheral edges of the stud ring are sealed, a through hole matched with the stud is formed on the stud ring, and the stud is in interference fit with the through hole. The utility model has the following benefits: since the hairspring stud is placed in the round hole with elastic pressure and is in contact with the peripheral part of the through hole, the working stability of the hairspring stud is good, and at the same time, the hairspring stud can be adjusted to be in the best position by clamping the upper end of the stud. The structure has few parts and good manufacturability, and is particularly suitable for thin and mini-type watch movements.
Description
Technical field
The utility model relates to a kind of fixed sturcture of watch hairspring stud, particularly relates to the hairspring stud fixed sturcture that a kind of suitable small size movement and slim movement use.
Background technology
Hairspring stud is the spud pile of hairspring outer end in the escapement hairspring vibrational system of wrist-watch.Hairspring stud is linked together the formation parts with outer anchor ear, and these parts can be done the adjustment of certain angle around the escapement center, and stud is determined on correct orientation.
Fig. 1 is a hairspring stud fixed connection structure synoptic diagram in the prior art.As shown in Figure 1, the hairspring stud fixed sturcture comprises: hairspring stud 1, outer anchor ear 2, stud pipe 3 and screw 4; Described outer anchor ear 2 rivets together with stud pipe 3, is formed with the hole of a correspondence on described outer anchor ear 2 and the stud pipe 3, and described hairspring stud 1 passes outer anchor ear 2 packs in stud pipe 3 holes, and the hole of described screw 4 by stud pipe 3 sides be hairspring stud 1 fixedly; Said structure is a stud fixed sturcture commonly used in the prior art, and it is convenient to installing/dismounting and adjustment, and its shortcoming is that part is more, and it is big to take up room, be difficult in slim and the small size movement in adopt.Fig. 2 a is the cut-open view of hairspring stud fixed sturcture in the prior art; Fig. 2 b is the vertical view of hairspring stud fixed sturcture in the prior art.Shown in Fig. 2 a and 2b, the hairspring stud fixed sturcture comprises: hairspring stud 1 and outer anchor ear 2; Shown in the side of outer anchor ear 2 be formed with elastic opening, described hairspring stud 1 is clamped by the elastic opening of outer anchor ear 2, the shortcoming of this structure be outer anchor ear 2 elastic opening intensity a little less than, frangibility, processes is difficult, is not suitable for batch process.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, provides a kind of simple in structure, good manufacturability, the hairspring stud fixed sturcture of reliable operation.
The technical scheme that the utility model adopted is: a kind of fixed sturcture of watch hairspring stud; Comprise hairspring stud and outer anchor ear; The neighboring sealing of described outer anchor ear, and be formed with the through hole suitable on the anchor ear outside, described stud and through hole interference fit with stud.
One side of described through hole is formed with section C.
The beneficial effects of the utility model are: because hairspring stud is placed the circular hole of being with elastic pressure, hairspring stud and one week of through hole contact, so the good operating stability of hairspring stud is adjusted hairspring stud to best orientation by the upper end of clamping stud simultaneously.This constitutional detail is few, and good manufacturability is particularly suitable for slim, small-sized timepiece movement and uses.

Embodiment
Be described in further detail below in conjunction with the fixed mechanism of the drawings and specific embodiments the utility model watch hairspring stud:
Fig. 3 a is the cut-open view of the utility model hairspring stud fixed sturcture; Fig. 3 b is the vertical view of the utility model hairspring stud fixed sturcture.Shown in Fig. 3 a and Fig. 3 b, the fixed sturcture of the utility model watch hairspring stud; Comprise hairspring stud 1 and outer anchor ear 2; The sealing of the neighboring of described outer anchor ear 2, and be formed with the through hole 21 suitable, described stud 1 and through hole interference fit outside on the anchor ear 2 with stud 1.One side of described through hole 21 is formed with section C; Thereby outer anchor ear 2 produces elastic deformation and clamps hairspring stud 1.Be formed with two planes of A, B in the upper end of described hairspring stud 1, when the orientation of the opening K of the hairspring of hairspring stud 1 lower end need be adjusted, can clamp A, the B face rotates hairspring stud 1, reaches desirable position.When hairspring stud 1 is installed simultaneously, rely on its outer chamfering to import and cooperate, so installation is convenient, firm.Plane contact on the P face of hairspring stud 1 and the outer anchor ear 2 has guaranteed the axial location of hairspring stud 1.
The characteristics of the utility model hairspring stud fixed sturcture are simple in structure, reliable operation, and easy to adjust, part is firm, good manufacturability.Hairspring stud 1 compared with prior art described in the utility model is that side face contacts with through hole 21, so hairspring stud is stressed evenly, steadiness is good, difficult drop-off.The shape of outer anchor ear 2 clamping hairspring studs 1 is firm, and the intensity height is easy to processing, can fracture damage.
It is worthy of note; protection domain of the present utility model is not limited to above-mentioned embodiment; according to basic fundamental design of the present utility model, as long as the embodiment that those of ordinary skills need not can associate by creative work all belongs to protection domain of the present utility model.
