Description

Technical Field

[0001] This utility model relates to the field of watch manufacturing, and more specifically, to a watch glass cover with an enlarged structure. Background Technology

[0002] The watch crystal is a transparent component covering the outside of the watch face. It is an important part of the watch and mainly serves to protect the core components inside, such as the dial, hands, and markers. It can effectively resist damage to the internal components from dust, moisture, scratches, and daily impacts, while ensuring that the dial information is clearly visible so that users can accurately read the time and other information.

[0003] The existing technologies on the market still have the following shortcomings:

[0004] (1) It is difficult to accurately align with a specific area of the dial, making it impossible to achieve precise magnification. At the same time, it is impossible to finely adjust the position of the magnified structure, making it difficult for people with poor eyesight to clearly read the small information on the dial, greatly reducing the ease of use.

[0005] (2) The installation is not stable enough and has poor adaptability, resulting in low practical value. Furthermore, it is impossible to firmly fix the cover plate on different watch models, leading to poor adaptability. The overall structure makes it difficult to balance connection stability and adjustment flexibility, which makes the magnification function easily affected during use, resulting in low practical value.

[0006] Therefore, a watch glass cover with an enlarged structure was proposed. Utility Model Content

[0007] The purpose of this utility model is to address the existing problems.

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] The present invention is as follows: a watch glass cover with a magnifying structure, comprising a main body, a fixing rod fixedly connected to the upper surface of the cover body, a glass panel being limited and snapped onto the side surface of the fixing rod, and a limiting insert rod fixedly connected inside the cover body.

[0010] The outer ring surface of the limiting plug is fitted with a limiting sleeve block, the outer ring surface of the limiting sleeve block is fitted with a support plate, and the bottom surface of the support plate is fixedly connected with a plug-in bottom ring.

[0011] One side of the insertion bottom ring is fixedly connected to an anti-slip fixing foot, and the outer ring surface of the cover plate body is fixedly connected to a fixing block, with a nut fixedly connected to one side of the fixing block.

[0012] As a preferred technical solution of this utility model, the inner ring surface of the support piece is provided with a snap-fit opening, and the size of the snap-fit opening and the limiting rod are matched. The snap-fit opening allows the support piece to be precisely connected with the limiting rod, which not only ensures the smoothness of the support piece sliding on the limiting rod, but also avoids shaking or deviation during the sliding process, ensuring that the support piece drives the magnification-related components to move stably, thereby accurately aligning with the area of the dial that needs to be magnified and improving the accuracy of the magnification function.

[0013] As a preferred technical solution of this utility model, a threaded rod is inserted into the inner ring surface of the nut for limiting, and the threaded rod is connected between the nut and the fixing block. The threaded rod and the nut for limiting and inserting are engaged, and the extension and retraction of the threaded rod can achieve the tightening and loosening of the support plate, which facilitates the quick fixing or adjustment of the position of the magnification structure. At the same time, this connection method is stable and reliable, and can effectively prevent the magnification structure from shifting due to external forces during use, ensuring the stability of the magnification effect.

[0014] As a preferred technical solution of this utility model, the nut is connected to the cover plate body through a fixing block, and the fixing blocks are symmetrically arranged with the vertical center line of the nut as the axis of symmetry. The symmetrically distributed fixing blocks can fix the nut evenly and firmly on the cover plate body, so that the nut will not tilt or loosen when the threaded rod is rotated and adjusted, which enhances the stability of the overall structure and provides a solid foundation for the adjustment operation of the threaded rod.

[0015] As a preferred technical solution of this utility model, a knob handle is fixedly connected to the upper surface of the threaded rod, and the knob handle is connected between the threaded rod and the nut. The knob handle increases the contact area between the hand and the threaded rod, allowing the user to rotate the threaded rod more easily and effortlessly, simplifying the operation process of adjusting the position of the enlarged structure. Even users with less hand strength can easily complete the fixing or loosening action, improving the convenience of use.

[0016] As a preferred technical solution of this utility model, the inner surface of the limiting sleeve is provided with an installation opening, and the size of the installation opening and the limiting rod are matched. The installation opening allows the limiting sleeve to be tightly fitted onto the limiting rod, providing auxiliary support for the support plate and further reducing the wobbling of the support plate during sliding. At the same time, this matching design also ensures the fitting accuracy between the limiting sleeve and the limiting rod, making the movement of the support plate more stable and helping to improve the accuracy of the magnified structure adjustment.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. The magnifying structure is stably supported by the cooperation of the limiting rod, limiting sleeve, and support plate. The limiting sleeve, which fits onto the outer ring of the limiting rod, has an installation opening that matches the size of the limiting rod. The snap-fit opening of the inner ring of the support plate also matches the limiting rod. By adjusting the position of the support plate on the limiting rod, the insertion bottom ring and related magnifying components can be moved, achieving precise magnification of specific areas of the dial. Meanwhile, the fixing blocks are symmetrically arranged with nuts perpendicular to the center line. The threaded rod is connected by the nut, and the extension and retraction of the threaded rod can be adjusted by rotating the knob handle, further fine-tuning the position of the magnifying structure. This allows users to clearly read small information on the dial, making it especially suitable for people with poor eyesight and significantly improving ease of use.

[0019] 2. The glass panel is secured by a fixing rod on the upper surface of the cover plate, ensuring a firm installation and preventing it from easily falling off. Anti-slip feet on the bottom ring side enhance the stability of the connection between the cover plate and the watch, preventing slippage and displacement during use. The connection structure between the fixing block and the nut, combined with the tightening effect of the threaded rod, firmly fixes the cover plate to the watch, adapting to the installation requirements of different watch models. The overall structural design balances the stability of the connections between components with the flexibility of adjustment, ensuring the magnification function works stably during use and enhancing the usability of the watch glass cover plate.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] Please see Figure 1-4 The present invention provides a technical solution: a watch glass cover with an enlarged structure, including a cover body 1, a fixing rod 2 fixedly connected to the upper surface of the cover body 1, a glass panel 3 limited and snapped onto the side surface of the fixing rod 2, and a limiting insert rod 11 fixedly connected inside the cover body 1.

[0030] In this embodiment, the inner ring surface of the support plate 6 is provided with a snap-fit opening 14, and the size of the snap-fit opening 14 and the limiting rod 11 are matched. The snap-fit opening 14 allows the support plate 6 to precisely align with the limiting rod 11, ensuring the smooth sliding of the support plate 6 on the limiting rod 11 and preventing shaking or displacement during sliding. This ensures that the support plate 6 drives the magnification-related components to move stably, thereby accurately aligning with the area of the dial that needs to be magnified and improving the accuracy of the magnification function. The inner ring surface of the nut 8 is fitted with a threaded rod 9, which is connected to the fixing block 7 through the nut 8. The threaded rod 9 and the limiting insertion of the nut 8 are matched, and the extension and retraction of the threaded rod 9 can tighten and loosen the support plate 6, facilitating quick fixing or adjustment of the position of the magnification structure. At the same time, this connection method is stable and reliable, effectively preventing the magnification structure from shifting due to external forces during use and ensuring the stability of the magnification effect.

[0031] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, a limiting sleeve block 12 is fitted onto the outer ring surface of the limiting insert rod 11, and a support piece 6 is fitted onto the outer ring surface of the limiting sleeve block 12.

[0032] In this embodiment, the nut 8 is connected to the cover plate body 1 via a fixing block 7. The fixing blocks 7 are symmetrically arranged about the vertical center line of the nut 8. The symmetrically distributed fixing blocks 7 can evenly and firmly fix the nut 8 to the cover plate body 1, preventing the nut 8 from tilting or loosening when the threaded rod 9 is rotated for adjustment. This enhances the stability of the overall structure and provides a solid foundation for the adjustment operation of the threaded rod 9. A knob handle 10 is fixedly connected to the upper surface of the threaded rod 9, and the knob handle 10 is connected to the nut 8 via the threaded rod 9. The knob handle 10 increases the contact area between the hand and the threaded rod 9, allowing the user to rotate the threaded rod 9 more easily and effortlessly, simplifying the operation process of adjusting the position of the enlarged structure. Even users with less hand strength can easily complete the fixing or loosening actions, improving the ease of use.

[0033] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, a bottom ring 4 is fixedly connected to the bottom surface of the support plate 6, an anti-slip fixing foot 5 is fixedly connected to one side of the bottom ring 4, a fixing block 7 is fixedly connected to the outer ring surface of the cover plate body 1, and a nut 8 is fixedly connected to one side of the fixing block 7.

[0034] In this embodiment, the inner surface of the limiting sleeve 12 has an installation opening 13, and the size of the installation opening 13 and the limiting rod 11 are matched. The installation opening 13 allows the limiting sleeve 12 to fit tightly onto the limiting rod 11, providing auxiliary support for the support piece 6 and further reducing the wobbling of the support piece 6 when sliding. At the same time, this matching design also ensures the fitting accuracy between the limiting sleeve 12 and the limiting rod 11, making the movement of the support piece 6 more stable and helping to improve the accuracy of the magnified structure adjustment.

[0035] Specifically, when using this watch glass cover with magnification structure: The fixing rod 2 is fixedly connected to the upper surface of the cover body 1, and the glass panel 3 is secured to the side surface of the fixing rod 2, ensuring the glass panel 3 is firmly and flat. A limiting insert rod 11 is fixedly connected inside the cover body 1. The limiting sleeve 12 is fitted onto the outer surface of the limiting insert rod 11 through the inner ring's mounting opening 13. The support piece 6 is then fitted onto the outer surface of the limiting sleeve 12 through the inner ring's snap-fit opening 14, completing the assembly of the magnification structure support part. A bottom ring 4 is fixedly connected to the bottom surface of the support piece 6, and an anti-slip fixing foot 5 is installed on one side of the bottom ring 4 to provide stable support for the magnification structure. Nuts 8 are connected to the outer surface of the cover body 1 via fixing blocks 7. The fixing blocks 7 are symmetrically arranged with the vertical center line of the nut 8 as the axis of symmetry, ensuring the nut 8 is securely installed. The threaded rod 9 is inserted into the inner ring surface of the nut 8. The upper surface of the threaded rod 9 is fixedly connected to the knob handle 10 for easy adjustment. To read the desired dial area, slide the support piece 6, moving it on the limit sleeve 12 and the limit rod 11. This moves the bottom ring 4 and related magnifying components to adjust their positions, achieving alignment of the specific area of the dial. After adjustment, rotate the knob handle 10 to extend and retract the threaded rod 9 within the nut 8, tightening the support piece 6 or related components to fix the magnifying structure in its current position. The anti-slip fixing foot 5 further enhances overall stability and prevents displacement during use. In daily use, the dial information can be clearly read through the glass panel 3 and the adjusted magnifying structure. If the magnified area needs to be changed, rotate the knob handle 10 in the opposite direction, loosen the threaded rod 9, slide the support piece 6 again to adjust its position, and then fix it again. Regularly check the connections of each component, such as whether the fixing rod 2 and the glass panel 3 are securely connected, and whether the limit sleeve 12 and the limit rod 11 are smoothly engaged, to ensure the normal use of the cover plate.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
