Description

Technical Field

[0001] The utility model relates to the field of clock movement, in particular to a quartz clock movement with a stator sheet fixing device. Background Art

[0002] The applicant disclosed a quartz clock movement with a stator plate fixing device in Chinese patent document CN203520037U, which includes a stator plate, a closing plate and a stator plate fixing plate; the stator plate fixing plate is directly pressed against the stator plate and the closing plate, so that the stator plate and the closing plate are closely stacked to ensure the magnetic conductivity between each other, and at the same time, it plays a fastening role on the stator plate and the closing plate; the stator plate fixing plate is provided with a positioning leg and a positioning buckle plate; the movement is provided with a slot for fixing the positioning leg and a buckle slot for fixing the positioning buckle plate at the position where the stator plate fixing plate is installed, so that the positioning leg of the stator plate fixing plate can be extended into the slot on the movement, and the positioning buckle plate of the stator plate fixing plate can be assembled in the buckle slot of the movement. Through the above technical solution, it is possible to assemble and fix the stator plate and the closing plate without screws; at the same time, when an assembly error is found, it is easy to disassemble and the positioning structure of the movement is stable and not loose during operation.

[0003] However, the inventors found that Figure 1 As shown, the corresponding specification in the Chinese patent document CN203520037U is attached Figure 2 There is still a gap 24 between the closing piece 2 and the bottom of the movement bridge 4, and this gap 24 does not generate any force, so that the closing piece 2 and the stator piece 1 cannot be completely tightly stacked. This is because only a unidirectional force acts on the stator piece, and it cannot ensure that the gap between the closing piece and the bottom is eliminated and completely pressed.

[0006] The technical solutions adopted are:

[0007] A quartz clock movement with a stator plate fixing device, the stator plate fixing device comprising a stator plate, a closing plate, a stator plate fixing plate and a movement clamping plate, the stator plate and the closing plate are stacked on the movement clamping plate in sequence; the stator plate fixing plate is provided with a first convex point, and the stator plate fixing plate is pressed on the stator plate through the first convex point; one end of an elastic device is fixed on the movement clamping plate, and the other end of the elastic device is provided with a second convex point, and the second convex point presses on the closing plate.

[0013] The utility model adds an elastic device located on the movement clamping plate.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only partial embodiments of the utility model, not all embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 2-Figure 5 As shown, a quartz clock movement with a stator plate fixing device comprises a stator plate 1, a closing plate 2, a stator plate fixing plate 3 and a movement clamping plate 4, wherein the stator plate 1 and the closing plate 2 are sequentially stacked on the movement clamping plate 4; the stator plate fixing plate 3 is provided with a first convex point 31, and the stator plate fixing plate 3 is pressed on the stator plate 1 through the first convex point 31; one end of an elastic device 5 is fixed on the movement clamping plate 4, and the other end of the elastic device 5 is provided with a second convex point 51, and the second convex point 51 presses on the closing plate 2.

[0022] In this way, compared with the prior art CN203520037U, an elastic device is added on the movement clamp. Since the stator plate fixing plate 3 is pressed on the stator plate 1 through the first protrusion 31, and the second protrusion 51 is pressed on the closing plate 2, the upper and lower forces are realized, making the closing plate 2 and the stator plate 1 more firmly stacked.

[0023] That is, the elastic device located on the movement clamp eliminates the non-acting force generated by the gap 24 between the closing plate and the bottom of the movement clamp, so that the closing plate and the stator plate can be completely and tightly stacked.

[0024] The elastic device can be implemented in many ways. One specific implementation is: the elastic device 5 is an inverted U-shaped elastic sheet 5, and a second protrusion is fixed in the middle of the elastic sheet.

[0025] In another specific implementation, there are two elastic sheets 5 , the two elastic sheets 5 are spaced apart, and the second protrusions 51 are welded to the middle ends of the two elastic sheets 5 .

[0026] The number of elastic devices is set according to actual needs, and can be 2, which are set at intervals.

[0027] The function of the elastic device is to provide an upward pressure on the closing plate and eliminate the inactive force generated by the gap between the closing plate and the bottom of the movement splint.

[0028] As a preferred specific implementation, the stator sheet fixing plate 3 is provided with a positioning foot 32 and a positioning hook 33, and the movement clamp plate 4 is provided with a slot 41 and a hook slot 42, the hook slot 42 is arranged at the lower side of the movement clamp plate 4, the positioning foot 32 is inserted into the slot 41 for fixing, and the positioning hook 33 is pressed into the lower side and clamped in the hook slot 42.

[0029] Thus, compared with the prior art CN203520037U, the process of the first convex point pressing down the stator sheet by the positioning hook into the hook groove located below the side of the movement clamp is the process of the first convex point pressing down the stator sheet. There is no need to deform the stator sheet fixing plate. The deformed stator sheet fixing plate is relatively more susceptible to damage, because the deformation ability of the material used to make the stator sheet fixing plate is generally weak.

[0030] The number of the first protrusions may be multiple, for example, 3, 4 or 5, distributed at intervals. The number of the second protrusions may be 1 or multiple, for example, 2.

[0031] Since the first protrusion generates downward pressure on the stator sheet and the second protrusion generates upward pressure on the closing sheet, the upper and lower pressures cause the stator sheet and the closing sheet to be more closely stacked and more firmly fitted together.

[0032] The series of detailed descriptions listed above are only specific descriptions of feasible embodiments of the present invention. They are not intended to limit the protection scope of the present invention. All equivalent embodiments or changes that do not deviate from the technical spirit of the present invention should be included in the protection scope of the present invention.
