Abstract
The utility model discloses a fixing device of a watch display disc, which comprises a display wheel and a back-up ring. The display wheel is disposed on a clamping plate. A gap between the radial direction and the axial direction of the display wheel is controlled by a jewel bearing. Two projections are sequentially formed on the top of the display wheel. The back-up ring is an annular opening. The back-up ring is sleeved on the display wheel and cooperated with the display wheel in a friction manner. The beneficial effects of the utility model are that the back-up ring and the display having the projections with conicity are directly pressed and fixed to be one body, thereby solving a problem of the prior art that the combined calendar display on a display disc is liable to offset through fixing by a screw; and certain friction moment exists between the back-up ring and the display wheel so that the back-up ring and the display wheel rotate correspondingly under the effect of certain external moment, therefore, if one display disc serves as a basis and the other display disc is slightly adjusted, the combined calendar display of a large calendar is more consistent.
Description
Technical field
The utility model relates to a kind of stationary installation of wrist-watch parts, particularly relates to the stationary installation of display panel in a kind of wrist-watch.
Background technology
A kind of big calendar indication mechanism that takies minimum position letter disk and ten the coaxial setting of letter disk in plane is arranged in the calendar indication mechanism of wrist-watch; Like patent publication No. is CN201181402Y; A kind of wrist-watch letter disk coaxial-type big calendar indication mechanism is disclosed; As depicted in figs. 1 and 2, a position letter disk of this mechanism and the rotation center of ten letter disks are coaxial, and wherein ten wheels and ten letter disks are fixed through screw.But screw retention has shortcoming: as, because clamp load torque when screwing screw, driving ten letter disks when screwing sometimes has a displacement, there are the situation of dislocation in the numeral that makes ten letter disks and a numeral of position letter disk.
Summary of the invention
The utility model technical matters to be solved is, overcomes the deficiency of prior art, and a kind of not only fixing display panel but also can finely tune the stationary installation of display panel is provided.
The technical scheme that the utility model adopted is: the stationary installation of watch displays dish, comprise, and show wheel and back-up ring; Said demonstration wheel is arranged on the clamping plate; And through jewel bearing control show wheel radially with axial gap; The top that said demonstration is taken turns is formed with two convexities in regular turn, and said back-up ring is an annular opening, and said shield ring sleeve is contained in and shows that wheel is gone up and take turns frictional fit with demonstration.
Said demonstration wheel comprises ten wheels, phases of the moon wheel, week calendar wheel and monthly calendar wheel.
Said convexity is circle and taper from the bottom to top in regular turn, and the tapering of tapered protrusion is that 1 degree is to 10 degree.
The material that said back-up ring is selected for use is steel or beryllium-bronze.
Be coaxially arranged with the position wheel and a position letter disk that pressing is an one on said ten wheels, said position wheel can freely rotate with a position letter disk; The circular protrusions of said ten wheel ends is provided with ten wheel shafts and ten letter disks that pressing is an one; Said back-up ring is installed on the tapered protrusion on ten wheel tops.
The beneficial effect of the utility model is: the protruding directly pressing and fixing that has tapering through back-up ring and demonstration wheel becomes one; Solved that screw threads fastens the generation that the display panel Combined calendar that brings shows inconsistent phenomenon in the prior art; Simultaneously since back-up ring with show that also having certain moment of friction between the wheel can make back-up ring relatively rotate under the effect of moment of face necessarily with showing wheel; Therefore serve as further another display panel of fine setting of basis with a display panel, can the Combined calendar of big calendar be shown consistent more.

Embodiment
Through accompanying drawing and embodiment the utility model is done further explain below:
Like Fig. 3 to Fig. 5, Fig. 7 is to shown in Figure 9, and the stationary installation of display panel comprises in the utility model wrist-watch, shows wheel and back-up ring 4; Said demonstration wheel is arranged on the clamping plate; And through jewel bearing control show wheel radially with axial gap; The top of said demonstration wheel is formed with two convexities in regular turn, and said convexity is circle and taper from the bottom to top in regular turn, and the tapering of tapered protrusion is that 1 degree is to 10 degree; Said back-up ring 4 is an annular opening, and said back-up ring 4 is sleeved on and shows that wheel is gone up and take turns frictional fit with demonstration; Said demonstration wheel comprises ten wheels, phases of the moon wheel, week calendar wheel and monthly calendar wheel; The material that said back-up ring 4 is selected for use is steel or beryllium-bronze elastomeric material.
Embodiment 1, and the fixed sturcture when at present being dial with the watch displays dish describes:
The stationary installation of the utility model watch displays dish comprises, ten wheels 1, individual position wheel 2a, individual position letter disk 2b, ten wheel shaft 3a, ten letter disk 3b, back-up ring 4; Said ten wheels 1 are arranged on the clamping plate, and through ten wheels 1 of two jewel bearings control radially with axial gap, it should be noted that there are two convexities on the top of ten wheels 1; One of them is a circular protrusions; And another is the tapered protrusion that has tapering, and tapering is that 1 degree is chosen between 10 degree, said position wheel 2a and a position letter disk 2b pressing be one and with the 1 coaxial setting of ten wheels; Pressing is that a position wheel 2a of one can freely rotate with a position letter disk 2b; Said ten wheel shaft 3a and ten letter disk 3b pressing are one and are arranged on the circular protrusions on ten wheel 1 tops that played the effect of centralized positioning, said back-up ring 4 is an annular opening; Back-up ring 4 is with coaxial the fitting in of tapered protrusion of ten wheels 1; Make ten wheel shaft 3a and ten letter disk 3b and ten wheels 1 be fixed as one, it should be noted that back-up ring 4 and ten wheels 1 are frictional fit, can overcome the moment of friction that has between the two through certain moment of face; Make their relative motions, to reach ten letter disk 3b of fine setting and a highly consistent purpose of position letter disk 2b Combined calendar numeral.
The protruding directly pressing and fixing that has tapering through back-up ring and ten wheels becomes one; Solve screw threads in the prior art and fastened ten letter disks and a generation of position letter disk Combined calendar numeral inconsistent phenomenon that bring; Simultaneously since also have certain moment of friction between back-up ring and ten wheels can be so that back-up ring relatively rotates under the effect of certain moment of face with ten wheels, therefore be with the unit numbers basis further fine setting tens word with the Combined calendar demonstration unanimity of big calendar.
In like manner, the fixed sturcture that phases of the moon wheel, week calendar wheel and monthly calendar are taken turns is identical with embodiment 1, repeats no more at this.
It is worthy of note that the protection domain of the utility model is not limited to above-mentioned instantiation mode, according to the basic fundamental design of the utility model; Also can essentially identical structure; As shown in Figure 6, ten letter disks of block form big calendar can pass through back-up ring simultaneously with a position letter disk, adjust the position of two calendar numerals again according to frictional fit; Still can realize the purpose that this is novel; As long as those of ordinary skills need not through creative work, the embodiment that can associate all belongs to the protection domain of the utility model.
