Description

Technical Field

[0001] The utility model relates to the technical field of diving watches, in particular to a waterproof structure of a diving watch. Background Art

[0002] A waterproof diving watch is a watch designed specifically for underwater activities, with good waterproof performance and capable of withstanding the water pressure at a certain depth without being damaged. Such watches usually have a waterproof ring installed inside to keep the inside of the watch dry under the action of water pressure. Since water is corrosive, diving watches are usually made of corrosion-resistant materials such as stainless steel, titanium alloy or special alloys.

[0003] For an existing Chinese patent with the reference publication number CN218585181U, it discloses a waterproof structure of a diving watch, including a diving watch main body. One side of the diving watch main body is provided with a charging port. A waterproof box is fixedly connected to the side of the diving watch main body close to the charging port. One side of the waterproof box is provided with a socket. A sealing plate is arranged inside the socket. The top end of the sealing plate slides through the inner wall of the socket and extends outside the waterproof box. On one side inner wall of the waterproof box, there are two symmetrically arranged grooves. Slide bars are fixedly connected to both of the two grooves. A slider is slidably sleeved on the slide bar. One end of the slider is fixedly connected to a water blocking plate. An elastic mechanism is sleeved on the slide bar. Two ends of the elastic mechanism are respectively fixedly connected to the slider and the inner wall of the groove, which is convenient for protecting the charging socket and preventing water from entering the charging socket, thereby preventing the watch case from being damaged.

[0004] This structure uses elastic rebound as the source of resistance. When the charging cable is pulled out, the elastic mechanism in a compressed state under its own elastic force prompts the water blocking plate to return to its initial position. The two water blocking plates abut against each other to seal the charging port. The utility model is convenient for protecting the charging socket and preventing water from entering the charging socket, thereby preventing the watch case from being damaged. Although it has a blocking effect, its cooperation precision is relatively high. When a single component cannot cooperate, it will cause a series of abnormal linkages in mechanical cooperation, resulting in the paralysis of the watch waterproof structure. In addition, when affected by the action of impact force or water pressure, it may cause the elastic mechanism to not rebound or not fully rebound, resulting in liquid seeping into the inside of the watch, thereby causing irreparable damage. When in use, its structure needs to be processed and improved again, which increases the process and reduces the work efficiency. For this reason, the inventor has proposed a waterproof structure of a diving watch to solve the above-mentioned technical problems. Summary of the Utility Model

[0005] The utility model aims to provide a technical solution that can solve the above problems to overcome the above deficiencies.

[0006] A waterproof structure for a diving watch, comprising a dial and a strap. A connecting platform is provided on the surface of the dial. The strap is in contact with the surface of the connecting platform through a rotating shaft. The middle part of the dial is a pointer dial. A transparent gasket for protecting the hour hand is provided on the surface of the pointer dial. Fixing grooves are formed at the edge of the pointer dial. The fixing grooves are annularly distributed at the edge of the pointer dial. The distance between adjacent fixing grooves is equidistantly arranged. The fixing grooves are concave in shape. Transparent epoxy resin glue is filled between the fixing grooves and the transparent gasket. A sealant is provided inside the dial. One end of the dial is provided with a bottom plate. An interference fit is provided between the dial and the bottom plate. One end of the bottom plate is in contact with one end of the sealant;

[0007] The epoxy resin glue is prepared by mixing epoxy resin AB glue. Epoxy resin AB glue is a two-component adhesive, composed of resin (component A) and hardener (component B). When in use, the two components are mixed in a certain proportion, and a chemical reaction starts after mixing and gradually cures to form a hard bonding layer. This adhesive has excellent bonding performance, chemical resistance, electrical insulation and mechanical strength;

[0008] When a transparent gasket is installed on the surface of the pointer dial, the transparency of the transparent gasket facilitates the user to directly observe the time displayed on the pointer dial through the transparent gasket. Then, the proportionally prepared epoxy resin glue is poured in. At this time, the epoxy resin glue is in a liquid state. The liquid epoxy resin glue is poured into the interior of the pointer dial. Due to the barrier of the transparent gasket, it is avoided that the epoxy resin glue affects the hour hand or the display screen of the pointer dial. The liquid epoxy resin glue fills the gap between the transparent gasket and the dial and spreads into the interior of the fixing grooves, effectively blocking the possibility of external liquid entering the watch interior;

[0009] When the epoxy resin glue hardens, since the epoxy resin glue fills the interior of the fixing grooves, the fixing grooves play a role in limiting the position of the epoxy resin glue, achieving the effect of preventing the epoxy resin glue from detaching. And the transparency of the hardened epoxy resin glue is relatively clear, and it can be directly used or polished after hardening, so that the user can directly observe the time displayed on the pointer dial through the epoxy resin glue;

[0010] And a sealant is provided inside the dial. One end of the dial is provided with a bottom plate. An interference fit is provided between the dial and the bottom plate. One end of the bottom plate is in contact with one end of the sealant. This structure can ensure the sealing performance inside the dial. By adopting two protective measures of blocking liquid entry at the top and bottom, it effectively prevents pollutants such as liquid or dust from entering, and at the same time helps to improve the stability and durability of the structure.

[0011] Furthermore, an adjustment buckle for adjusting the tightness of the strap is connected to the surface of the strap. An anti-slip band paired with the adjustment buckle is provided at one end of the strap;

[0012] The anti-slip band can ensure that after the adjustment buckle is adjusted, the probability of accidental sliding of the watch band is reduced, thus maintaining the stability and comfort of the watch band. By cooperating with the adjustment buckle, the anti-slip band increases the friction between the watch band and the wrist, preventing the watch band from slipping due to loosening during sports, daily activities or underwater activities, improving the wearing safety and convenience. In addition, the design of the anti-slip band can also increase the durability of the watch band and reduce the wear on the adjustment buckle caused by frequent adjustment.

[0013] Further, the connecting platform is in a convex shape and is a symmetric structure. The watch band makes a circular motion with the rotating shaft as the center point. The rotating shaft penetrates the surfaces at both ends of the connecting platform, and adjusting screws for adjusting the tightness of the rotating shaft are provided at both ends of the rotating shaft;

[0014] With this design structure, the user can adjust the tightness of the watch band according to personal comfort. This design ensures the fit between the watch band and the wrist, neither being too tight to cause discomfort nor being too loose to affect the stability and accuracy of the watch. The setting of the adjusting screws makes the adjustment process simple and convenient, and the user can easily adjust the tightness of the watch in different underwater situations to meet different wearing needs or personal preferences.

[0015] Further, a plurality of card slots are formed on the surface of the watch dial. The card slots are in a concave shape, and the distance between adjacent card slots is equally spaced. The card slots are annularly distributed on the inner edge of the watch dial, and a protection component for protecting the pointer dial is connected to the surface of the watch dial;

[0016] The concave shape of the card slots can effectively disperse the stress on the surface of the watch dial, preventing local deformation due to the influence of water pressure during use. The equal spacing of adjacent card slots ensures the uniform stress of the watch dial and improves the stability of the overall structure; in addition, the annular distribution of the card slots ensures that the protection component can be fixed in all directions on the watch dial, enhancing the protection effect on the pointer dial. The setting of the protection component can protect the pointer dial from external impact and wear, extend the service life of the pointer dial, and also improve the durability of the watch dial surface.

[0017] Further, the protection component includes a lens and a clamping block. The lens is a transparent lens. The clamping blocks are annularly distributed at one end of the lens. The clamping blocks are in the same shape as the card slots, and the clamping blocks and the card slots are in an interference fit structure. The diameter of the lens is the same as that of the watch dial;

[0018] The setting where the diameter of the lens is consistent with that of the dial can ensure a good fit between the lens and the dial, thus providing comprehensive protection. This design can prevent dust, moisture and other external factors that may damage the dial from entering the pointer dial. In addition, since the shapes of the clamping block and the clamping groove are the same and an interference fit structure is adopted, the fixing effect of the lens is further strengthened, reducing the probability that the lens will not easily shift or fall off in an underwater environment, thereby improving the overall stability and durability. Moreover, a transparent lens is used as the main structure of the lens, which is convenient for the user to directly observe the time displayed on the pointer dial through the lens.

[0019] Furthermore, a number of anti-collision rubber blocks for protecting the outer side of the dial are provided on the surface of the dial. The anti-collision rubber blocks are in a convex shape, annularly distributed on the outer side of the dial, and are consistent with the radian of the outer side of the dial. The distance between adjacent anti-collision rubber blocks is equally spaced.

[0020] The annular distribution setting can evenly disperse the external force impact, effectively protecting the dial from collision damage. The equally spaced distribution ensures the balance of protection, reduces the collision occurring at the annular angle, and can obtain corresponding buffering, thereby improving the overall durability and safety of the watch. The convex-shaped anti-collision rubber blocks can further reduce the probability of contact between the object and the surface of the dial, playing a protective role.

[0021] Compared with the prior art, the beneficial effects of the present utility model are: adopting two protective measures for blocking liquid entry at the top and bottom of the dial, effectively preventing pollutants such as liquid or dust from entering, and at the same time contributing to improving the stability and durability of the structure;

[0022] At the top, the gap between the transparent gasket and the dial is filled with liquid epoxy resin glue, and it spreads into the fixing groove, effectively blocking the possibility of external liquid entering the watch interior. When the epoxy resin glue hardens, the hardened epoxy resin glue can also play a role in protecting the dial and the pointer dial, reducing the possibility of damage to the pointer dial due to external force impact;

[0023] At the bottom, an interference fit setting between the dial and the bottom plate is adopted, so that one end of the bottom plate abuts against one end of the sealant. This structure can ensure the sealing performance inside the dial, effectively blocking the possibility of external liquid entering the watch interior. Adopting a single structure reduces the precise fit between components, reduces the failure of the waterproof structure caused by problems with a single structure, and achieves the effects of reducing the manufacturing cost and simplifying the structure for easy assembly.

Specific embodiments

[0032] The following further describes the present utility model in detail in conjunction with the accompanying drawings and specific embodiments.

[0033] In this embodiment, please refer to Figures 1-7 , a waterproof structure of a diving watch in its specific implementation, includes a dial 1 and a watch band 2. A connecting platform 3 is provided on the surface of the dial 1. The watch band 2 is in contact with the surface of the connecting platform 3 through a rotating shaft 4. The middle part of the dial 1 is a pointer plate 5. A transparent gasket 6 for protecting the hour hand is provided on the surface of the pointer plate 5. Fixing grooves 16 are formed on the edge of the pointer plate 5. The fixing grooves 16 are annularly distributed on the edge of the pointer plate 5. The distance between adjacent two fixing grooves 16 is equally spaced. The fixing grooves 16 are in a concave shape. A transparent epoxy resin glue 7 is filled between the fixing grooves 16 and the transparent gasket 6. A sealant 8 is provided inside the dial 1. One end of the dial 1 is provided with a bottom plate 17. An interference fit is provided between the dial 1 and the bottom plate 17. One end of the bottom plate 17 is in contact with one end of the sealant 8;

[0034] The epoxy resin glue 7 is prepared by mixing and modulating epoxy resin AB glue. Epoxy resin AB glue is a two-component adhesive, composed of resin (component A) and hardener (component B). When in use, the two components are mixed in a certain proportion, and a chemical reaction starts after mixing, gradually curing to form a hard bonding layer. This adhesive has excellent bonding performance, chemical resistance, electrical insulation and mechanical strength;

[0035] When a transparent gasket 6 is installed on the surface of the pointer dial 5, the transparency of the transparent gasket 6 facilitates the user to directly observe the time displayed on the pointer dial 5 through the transparent gasket 6. Then, the proportionally modulated epoxy resin glue 7 is poured in. At this time, the epoxy resin glue 7 is in a liquid state. The liquid epoxy resin glue 7 is poured into the interior of the pointer dial 5. Due to the blockage of the transparent gasket 6, it is avoided that the epoxy resin glue 7 affects the hour hand or the display screen of the pointer dial 5. The liquid epoxy resin glue 7 fills the gap between the transparent gasket 6 and the dial 1 and spreads into the interior of the fixing groove 16, effectively blocking the possibility of external liquid entering the watch interior;

[0036] After the epoxy resin glue 7 hardens, since the epoxy resin glue 7 fills the interior of the fixing groove 16, the fixing groove 16 plays a role in restricting the position of the epoxy resin glue 7 and has the effect of preventing the epoxy resin glue 7 from detaching. Moreover, the transparency of the hardened epoxy resin glue 7 is relatively clear, and it can be used directly or polished after hardening, so that the user can directly observe the time displayed on the pointer dial 5 through the epoxy resin glue 7;

[0037] And a sealant 8 is provided inside the dial 1. One end of the dial 1 is provided with a bottom plate 17. An interference fit is provided between the dial 1 and the bottom plate 17. One end of the bottom plate 17 abuts against one end of the sealant 8. This structure can ensure the sealing performance inside the dial 1. By adopting two protective measures of blocking liquid entry from the top and bottom, it effectively prevents pollutants such as liquid or dust from entering, and at the same time helps to improve the stability and durability of the structure.

[0038] An adjustment buckle 9 for adjusting the tightness of the watchband 2 is connected to the surface of the watchband 2. An anti-slip band 10 paired with the adjustment buckle 9 is provided at one end of the watchband 2;

[0039] The anti-slip band 10 can ensure that after the adjustment of the adjustment buckle 9, the probability of accidental sliding of the watchband 2 is reduced, thereby maintaining the stability and comfort of the watchband 2. By cooperating with the adjustment buckle 9, the anti-slip band 10 increases the friction between the watchband 2 and the wrist, prevents the watchband 2 from slipping due to loosening during sports, daily activities or underwater activities, and improves the wearing safety and convenience. In addition, the design of the anti-slip band 10 can also increase the durability of the watchband 2 and reduce the wear on the adjustment buckle 9 caused by frequent adjustment.

[0040] The connecting platform 3 is in a convex shape and is a symmetric structure. The watchband 2 makes a circular motion with the rotating shaft 4 as the center point. The rotating shaft 4 penetrates the surfaces at both ends of the connecting platform 3. Adjusting screws 11 for adjusting the tightness of the movement of the rotating shaft 4 are provided at both ends of the rotating shaft 4;

[0041] With this design structure, the user can adjust the tightness of the strap 2 according to personal comfort. This design ensures the fit of the strap 2 to the wrist, neither being too tight to cause discomfort nor too loose to affect the stability and accuracy of the watch. The setting of the adjustment screw 11 makes the adjustment process simple and convenient, and the user can easily adjust the tightness of the watch in different underwater situations to meet different wearing needs or personal preferences.

[0042] A number of card slots 12 are provided on the surface of the dial 1. The card slots 12 are concave in shape, and the distance between adjacent card slots 12 is equally spaced. The card slots 12 are annularly distributed on the inner edge of the dial 1. A protective component for protecting the pointer dial 5 is connected to the surface of the dial 1;

[0043] The concave shape of the card slots 12 can effectively disperse the stress on the surface of the dial 1, preventing local deformation due to the influence of water pressure during use. The equal spacing of adjacent card slots 12 ensures the uniform stress of the dial 1 and improves the stability of the overall structure; in addition, the annular distribution of the card slots 12 ensures that the protective component can be fixed in all directions on the dial 1, enhancing the protection effect on the pointer dial 5. The setting of the protective component can protect the pointer dial 5 from external impacts and abrasions, extend the service life of the pointer dial 5, and also improve the durability of the surface of the dial 1.

[0044] The protective component includes a lens 13 and a clamping block 14. The lens 13 is a transparent lens. The clamping blocks 14 are annularly distributed at one end of the lens 13. The clamping blocks 14 are the same shape as the card slots 12, and the clamping blocks 14 and the card slots 12 are in an interference fit structure. The diameter of the lens 13 is the same as that of the dial 1;

[0045] The setting that the diameter of the lens 13 is the same as that of the dial 1 can ensure a good fit between the lens 13 and the dial 1, thus providing comprehensive protection. This design can prevent dust, moisture and other external factors that may damage the dial from entering the pointer dial 5; in addition, since the clamping blocks 14 are the same shape as the card slots 12 and are in an interference fit structure, the fixing effect of the lens 13 is further strengthened, reducing the probability that the lens 13 will not easily shift or fall off in the underwater environment, thereby improving the overall stability and durability. And using a transparent lens as the main structure of the lens 13 facilitates the user to directly observe the time displayed on the pointer dial 5 through the lens 13.

[0046] A number of anti-collision rubber blocks 15 for protecting the outer side of the dial 1 are provided on the surface of the dial 1. The anti-collision rubber blocks 15 are convex in shape. The anti-collision rubber blocks 15 are annularly distributed on the outer side of the dial 1 and are consistent with the radian of the outer side of the dial 1. The distance between adjacent anti-collision rubber blocks 15 is equally spaced;

[0047] The adoption of a circular distribution setting can evenly disperse external force impacts, effectively protecting the dial 1 from collision damage. The equidistant distribution ensures the balance of protection, reduces collisions occurring at the circular angle, and can obtain corresponding buffering, thereby improving the overall durability and safety of the watch. The convex-shaped anti-collision rubber block 15 can further reduce the probability of contact between an object and the surface of the dial 1, playing a protective role.

[0048] The design key point of the present utility model lies in: adopting two protective measures for blocking liquid entry at the top and bottom of the dial 1, effectively preventing pollutants such as liquid or dust from entering, and at the same time also helping to improve the structural stability and durability;

[0049] At the top, the liquid epoxy resin glue 7 is used to fill the gap between the transparent gasket 6 and the dial 1, and spreads into the interior of the fixing groove 16, effectively blocking the possibility of external liquid entering the watch interior. When the epoxy resin glue 7 hardens, the hardened epoxy resin glue 7 can also play a role in protecting the dial 1 and the pointer plate 5, reducing the possibility of damage to the pointer plate 5 due to external force impact;

[0050] At the bottom, an interference fit setting between the dial 1 and the bottom plate 17 is adopted, so that one end of the bottom plate 17 abuts against one end of the sealant 8. This structure can ensure the sealing performance inside the dial 1, effectively blocking the possibility of external liquid entering the watch interior.

[0051] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, which should all be regarded as the protection scope of the present utility model.
