Description

Technical Field

[0001] This utility model relates to the field of watch manufacturing technology, specifically to a watch mainspring barrel limiting support structure. Background Technology

[0002] In traditional mainspring barrels, the deformation range of the mainspring spring lacks a precise limiting structure. Over long-term use, excessive deformation can lead to elasticity decay or breakage, affecting the timekeeping accuracy and lifespan of the watch.

[0003] A search revealed existing technology (application number: CN213622743U), which describes "a pre-installed spring-loaded mobile phone anti-theft device retractor box". This utility model's spring is installed inside a spring-fixing base shell, covered by a spring-limiting cover, and the spring box achieves its limiting position through the cooperation of a limiting protrusion and a limiting groove at the installation location.

[0004] However, the limiting structure of this device lacks adjustment components to flexibly adjust the limiting state, resulting in poor adaptability. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a clock spring barrel limiting support structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a clock spring barrel limiting support structure, comprising: a spring barrel, providing support for the device; an adjusting assembly, including a top cover, a rotating sleeve, and a rotating shaft, wherein the top cover is connected to the top of the spring barrel by bolts, the rotating sleeve is rotatably connected to the top cover, the rotating shaft has a thread in the middle, and the rotating shaft is threadedly connected to the rotating sleeve; and a limiting assembly, including a rotating disk, a slider, and a limiting plate, wherein the rotating disk is welded to the bottom of the rotating shaft, the slider is slidably connected to the top cover and the rotating disk, and the limiting plate is welded to the slider, and the limiting plate is an arc-shaped plate.

[0007] As a further description of the above technical solution:

[0008] The inside of the spring box is rotatably connected to a rotating shaft, and one end of a spring is fixedly connected to the side wall of the rotating shaft. The other end of the spring is fixedly connected to the side wall of the limiting plate.

[0009] As a further description of the above technical solution:

[0010] The upper part of the spring barrel is connected to the housing via a support column, and a control rod is rotatably connected to the side wall of the housing. The control rod is provided with anti-slip texture.

[0011] As a further description of the above technical solution:

[0012] One end of the control rod is welded with a worm gear, which is rotatably connected to the inner wall of the housing via a support plate.

[0013] As a further description of the above technical solution:

[0014] A worm gear is slidably connected to the top of the shaft via a key, and the worm gear meshes with the worm.

[0015] As a further description of the above technical solution:

[0016] The limiting component further includes: a first sliding groove, which is a straight groove on the top cover; and a second sliding groove, which is an arc-shaped groove on the rotating disk, and whose direction is inclined relative to the first sliding groove.

[0017] As a further description of the above technical solution:

[0018] There are six of each of the slide rail one, slide rail two, slider and limiting plate, which are evenly distributed around the center of the spring box.

[0019] This utility model has the following beneficial effects:

[0020] This structure, through the coordination of the adjustment component and the limiting component, can control the position of the limiting plate, converting rotational motion into linear sliding, thereby effectively limiting the deformation range of the spring and preventing excessive deformation.

[0021] Meanwhile, the power transmission of the worm gear and the multiple evenly distributed limiting components make the limiting more stable and uniform, improving the support effect on the mainspring components and ensuring the reliability of the watch's mainspring barrel operation.

[0030] Example 1:

[0031] like Figures 1 to 3 As shown, this embodiment provides a clock spring barrel limiting support structure, including: a spring barrel 1, providing support for the device; an adjustment assembly 2, including a top cover 21, a rotating sleeve 22, and a rotating shaft 23, the top cover 21 being connected to the top of the spring barrel 1 by bolts, the rotating sleeve 22 being rotatably connected to the top cover 21, the rotating shaft 23 having a thread in the middle, and the rotating shaft 23 being threadedly connected to the rotating sleeve 22; and a limiting assembly 3, including a rotating disk 31, a slider 34, and a limiting plate 35, the rotating disk 31 being welded to the bottom of the rotating shaft 23, the slider 34 being slidably connected to the top cover 21 and the rotating disk 31, and the limiting plate 35 being welded to the slider 34, the limiting plate 35 being an arc-shaped plate.

[0032] The rotating sleeve 22 is welded with protrusions.

[0033] Specifically, a rotating shaft 11 is rotatably connected inside the spring box 1, and one end of a spring spring 12 is fixedly connected to the side wall of the rotating shaft 11. The other end of the spring spring 12 is fixedly connected to the side wall of the limiting plate 35.

[0034] In this embodiment, the mainspring barrel 1, the adjustment component 2, and the limiting component 3 constitute a watch mainspring barrel limiting support structure according to this application.

[0035] Understandable, Figure 1 The illustrations only represent some of the components of the watch spring barrel; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 Due to limitations, the mainspring barrel of a watch can also include, compared to... Figure 1 More or fewer parts.

[0036] Example 2:

[0037] Specifically, the upper part of the spring box 1 is connected to the housing via a support column, and a control rod 24 is rotatably connected to the side wall of the housing. The control rod 24 is provided with anti-slip texture.

[0038] Specifically, a worm gear 25 is welded to one end of the control lever 24, and the worm gear 25 is rotatably connected to the inner wall of the housing through a support plate.

[0039] Specifically, a worm gear 26 is slidably connected to the top of the rotating shaft 23 via a key, and the worm gear 26 meshes with the worm 25.

[0040] In this embodiment, the rotation of the control lever 24 drives the worm gear 25 to rotate synchronously. The control lever 24 facilitates manual operation, and the anti-slip texture increases friction to prevent slippage. The rotation of the worm gear 25 drives the worm wheel 26 to rotate, and the worm wheel 26 drives the rotating shaft 23 to rotate. The rotating shaft 23 can slide up and down relative to the worm wheel 26, realizing the transmission of power from the worm gear 25 to the rotating shaft 23, while allowing the rotating shaft 23 to move axially.

[0041] Example 3:

[0042] Specifically, the limiting component 3 also includes: a first slide groove 32, which is a straight groove on the top cover 21; and a second slide groove 33, which is an arc-shaped groove on the rotating disk 31, with its direction inclined relative to the first slide groove 32.

[0043] Specifically, six slides 32, 33, 34 and 35 are provided, evenly distributed around the center of the spring box 1.

[0044] In this embodiment, the slider 34 is simultaneously embedded in both the first groove 32 and the second groove 33. When the rotating disk 31 rotates, the second groove 33 pushes the slider 34 to slide along the first groove 32, converting the rotational motion of the rotating disk 31 into the linear sliding of the slider 34. The six components move synchronously, forming a surrounding limit on the spring component from different directions, increasing the stability and uniformity of the limit, and improving the support effect on the spring component.

[0045] In actual use, the operator first fixes both ends of the spring 12 to the rotating shaft 11 and the limiting plate 35. Then, the rotating shaft 11 passes through the bottom of the spring box 1, and the top cover 21 is placed on the top of the spring box 1 and fixed with bolts. Then, the protrusion on the rotating sleeve 22 is rotated to lower the rotating shaft 23. The rotating shaft 23 drives the rotating disk 31 to lower, so that the rotating disk 31 presses against the side wall of the spring 12. Then, the control lever 24 is rotated, which drives the worm gear 25 to rotate. The worm gear 25 drives the worm wheel 26 to rotate. The worm wheel 26 drives the rotating shaft 23 and the rotating disk 31 to rotate, so that the second slide groove 33 moves relative to the rotating disk 31, so that the slider 34 slides along the first slide groove 32. The slider 34 drives the limiting plate 35 to move, limiting the displacement distance of the spring 12 release.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
