Description

Technical Field

[0001] This utility model belongs to the field of watch accessories, and in particular relates to a connection structure between a watch strap and a watch case. Background Technology

[0002] A watch, also known as a wristwatch, is a portable timekeeping product worn by a person. It typically consists of several parts, including a movement, a case, and a strap. The strap is the structure used to secure the watch to the user's wrist. Common straps are made of various materials such as leather, rubber, nylon, and stainless steel, and the ends of the strap are usually connected to the watch case via end links.

[0003] However, existing end links cannot restrict the upward flipping movement of the watch strap, thus affecting the stability of the watch and its overall aesthetics. To solve this problem, those skilled in the art may choose to press one side of the end link against the side wall of the watch case to suppress the upward flipping movement of the strap. However, when the end link is pressed firmly against the watch case, the flexibility of the strap's movement will be affected, thereby increasing the difficulty for the user to wear the watch and affecting the wearing comfort. Utility Model Content

[0004] In view of this, the present invention aims to propose a connection structure between the watch strap and the watch case to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A connection structure between a watch strap and a watch case includes: a connecting component, a limiting seat, and a support seat; the connecting component is disposed on the watch case and includes two parallel connecting lugs forming an installation channel between the two connecting lugs; the limiting seat is detachably disposed inside the installation channel, and a limiting surface is provided on the side wall of the limiting seat near the watch case, and the limiting surface abuts against the side wall of the watch case; the support seat includes: a support plate, a connecting block, and two supporting lugs; the connecting block is disposed on the side wall of the support plate near the limiting seat and is rotatably connected to the limiting seat; the two supporting lugs are respectively disposed at both ends of the support plate, and a connecting spring bar for connecting the end of the watch strap is provided between the two supporting lugs; a limiting pressure plate is also provided on the side wall of the limiting seat away from the watch case, and a receiving gap for accommodating the end of the watch strap is formed between the limiting pressure plate and the support plate.

[0007] Furthermore, the limiting surface is also provided with a limiting protrusion, and the casing is provided with a limiting groove for accommodating the limiting protrusion, and the top surface of the limiting protrusion abuts against the top inner wall of the limiting groove.

[0008] Furthermore, the limiting seat is provided with a receiving hole, and an assembly trunnion is provided inside the receiving hole. The connecting ear is provided with an assembly hole on the side wall near the installation channel for accommodating the end of the assembly trunnion.

[0009] Furthermore, the limiting seat is provided with an assembly cutout for accommodating the connecting block, the assembly cutout being connected to the receiving hole, and the connecting block being provided with a connecting hole for accommodating the assembly spring shaft.

[0010] Furthermore, the assembly cutout is provided with a first positioning surface, a first transition arc surface and a second positioning surface connected in sequence. The first positioning surface is parallel to the limiting pressure plate, and a first included angle is formed between the second positioning surface and the first positioning surface, and the first included angle is greater than 90 degrees. The connecting block is provided with a third positioning surface, a second transition arc surface and a fourth positioning surface connected in sequence. The third positioning surface is located on the top of the connecting block and is parallel to the bearing plate. A second included angle is formed between the fourth positioning surface and the third positioning surface, and the second included angle is less than 90 degrees.

[0011] Furthermore, the first included angle is between 115 degrees and 125 degrees, and the second included angle is between 55 degrees and 65 degrees.

[0012] Furthermore, the connecting ear has a clearance groove on the side wall near the mounting channel for accommodating the bearing ear.

[0013] Furthermore, the clearance groove is provided with a fifth positioning surface, a third transition arc surface, a sixth positioning surface and a guide slope connected in sequence. The fifth positioning surface is parallel to the limiting pressure plate, the sixth positioning surface is perpendicular to the fifth positioning surface, and the angle formed between the guide slope and the fifth positioning surface is greater than 90 degrees.

[0014] Compared with the prior art, the connection structure between the watch strap and the watch case described in this utility model has the following advantages:

[0015] This utility model describes a connection structure between a watch strap and a watch case. A limiting surface and a limiting pressure plate are provided on the limiting seat, and a connecting block on the support seat is rotatably connected to the limiting seat. After assembly, the end of the watch strap is connected to the support seat via a connecting spring bar, and the limiting surface abuts against the side wall of the watch case. At this point, relative rotation between the limiting seat and the watch case is impossible. Therefore, the presence of the limiting pressure plate suppresses the upward flipping action of the watch strap, thereby improving the wearing stability and overall aesthetics of the watch. Simultaneously, the support seat can flexibly flip the watch strap downwards, thus reducing the difficulty of wearing the watch, making it easier for the strap to wrap around the user's wrist, and improving the comfort of wearing the watch.

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] A connection structure between the watch strap and the watch case, which can be made by Figures 1-5 The following diagram illustrates the connection structure between the watch strap and the watch case in this embodiment: a connecting component, a limiting seat 3, and a support seat. The connecting component is disposed on the watch case 1 and includes two parallel connecting ears 2, forming an installation channel between the two connecting ears 2. The limiting seat 3 is detachably disposed inside the installation channel. The support seat includes a support plate 4, a connecting block 5, and two supporting ears 41. The connecting block 5 is disposed on the side wall of the support plate 4 near the limiting seat 3 and is rotatably connected to the limiting seat 3. The two supporting ears 41 are respectively disposed at both ends of the support plate 4, and a connecting spring bar 42 for connecting the end of the watch strap is provided between the two supporting ears 41.

[0029] During assembly, workers can attach the end of the watch strap to the carrier by connecting the spring bar 42. The strap is then assembled with the watch case 1 through the cooperation of the carrier, the limiting seat 3, and the connecting components. In use, because the connecting block 5 and the limiting seat 3 are connected by a rotating connection, the user can flexibly flip the strap to wrap it around the wrist for comfortable wear.

[0030] Optionally, to achieve a detachable connection between the limiting seat 3 and the connecting assembly, the limiting seat 3 may be provided with a receiving hole 34. An assembly trunnion 341 should be provided inside the receiving hole 34, and the connecting ear 2, near the mounting channel, should have an assembly hole 21 for receiving the end of the assembly trunnion 341, thereby completing the assembly between the limiting seat 3 and the connecting assembly using the assembly trunnion 341. Correspondingly, to achieve a rotatable connection between the connecting block 5 and the limiting seat 3, the limiting seat 3 should also have an assembly cutout for communicating with the receiving hole 34, and the connecting block 5 should have a connecting hole 51 for receiving the assembly trunnion 341. During assembly, the operator should first insert the connecting block 5 into the assembly cut and ensure that the connecting hole 51 is aligned with the receiving hole 34. Then, the assembly trunnion 341 is inserted through the connecting hole 51 along the receiving hole 34 so that the connecting block 5 can rotate around the assembly trunnion 341 as the rotation axis during use. Finally, the two ends of the assembly trunnion 341 are inserted into the assembly holes 21 of the two connecting ears 2 to complete the assembly work between the bearing seat, the limiting seat 3 and the connecting components.

[0031] To prevent the watch strap from flipping upwards during use, this embodiment provides a limiting surface 31 on the side wall of the limiting seat 3 near the watch case 1, and a limiting pressure plate 32 on the side wall of the limiting seat 3 away from the watch case 1. After assembly, the limiting surface 31 will abut against the side wall of the watch case 1, and a receiving gap will be formed between the limiting pressure plate 32 and the support plate 4 to accommodate the end of the watch strap. Since the limiting surface 31 abuts against the side wall of the watch case 1, the limiting seat 3 cannot rotate during use. When the watch strap tends to flip upwards, the limiting pressure plate 32 will suppress the movement of the watch strap, thereby preventing the watch strap from flipping upwards and improving the wearing stability and overall aesthetics of the watch.

[0032] As an optional implementation method of this embodiment, such as Figure 2 and Figure 3 As shown, a limiting protrusion 33 may be provided on the limiting surface 31, and a limiting groove 11 for accommodating the limiting protrusion 33 should be provided on the housing 1. After the assembly between the limiting seat 3 and the connecting component is completed, the limiting protrusion 33 will be inserted into the limiting groove 11. At this time, the top surface of the limiting protrusion 33 will abut against the top inner wall of the limiting groove 11, thereby further improving the fixing effect of the limiting seat 3.

[0033] Figure 4 This is a schematic diagram of the structure of the limiting seat 3. Figure 5 As shown in the figure, the first positioning surface 351, the first transition arc surface 352, and the second positioning surface 353 are sequentially connected inside the assembly cut, and the third positioning surface 521, the second transition arc surface 522, and the fourth positioning surface 523 are sequentially connected on the connecting block 5. Thus, the rotation stroke of the bearing seat is limited by the cooperation of the first positioning surface 351 and the third positioning surface 521, as well as the cooperation of the second positioning surface 353 and the fourth positioning surface 523.

[0034] Specifically, the first positioning surface 351 is parallel to the limiting pressure plate 32, and a first included angle is formed between the second positioning surface 353 and the first positioning surface 351, and the first included angle should be greater than 90 degrees. The third positioning surface 521 is set on the top of the connecting block 5, and the third positioning surface 521 is parallel to the bearing plate 4, and a second included angle is formed between the fourth positioning surface 523 and the third positioning surface 521, and the second included angle should be less than 90 degrees.

[0035] When the support is flipped upwards to its limit position, the third positioning surface 521 will abut against the first positioning surface 351. Since the first positioning surface 351 is parallel to the limiting pressure plate 32 and the third positioning surface 521 is parallel to the support plate 4, the limiting pressure plate 32 and the support plate 4 will not cause excessive pressure on the end of the watch strap in this state, thus protecting the watch strap. When the support is flipped downwards to its limit position, the fourth positioning surface 523 will abut against the second positioning surface 353. Since the first included angle is greater than 90 degrees and the second included angle should be less than 90 degrees, the fourth positioning surface 523 will have sufficient rotational travel before contacting the second positioning surface 353, so that the user can wrap the watch strap around their wrist and complete the comfortable wearing of the watch.

[0036] For example, in this embodiment, the first included angle can be between 115 degrees and 125 degrees, and the second included angle can be between 55 degrees and 65 degrees, so that when the support seat flips downward from the extreme position of upward flipping, it obtains a rotational stroke between 50 degrees and 70 degrees, thereby facilitating the user to wear the watch.

[0037] Furthermore, to further enhance the rotational stroke limitation capability of the bearing seat, this embodiment may also provide a relief groove 22 for accommodating the bearing ear 41 on the side wall of the connecting ear 2 near the installation channel, and within the relief groove 22 are a fifth positioning surface 231, a third transition arc surface 232, a sixth positioning surface 233, and a guide slope 234 connected in sequence. Figure 2As shown, the fifth positioning surface 231 should be parallel to the limiting pressure plate 32, the sixth positioning surface 233 should be perpendicular to the fifth positioning surface 231, and the angle formed between the guide slope 234 and the fifth positioning surface 231 should be greater than 90 degrees. When the bearing seat is flipped, the presence of the guide slope 234 facilitates the bearing ear 41 to disengage from or enter the clearance groove 22. When the bearing seat is flipped upward to the limit position, the top surface of the bearing ear 41 will abut against the fifth positioning surface 231, thereby strengthening the limiting effect on the bearing seat through the cooperation of the fifth positioning surface 231 and the top surface of the bearing ear 41.

[0038] The effects of the above solution are explained below:

[0039] This embodiment provides a connection structure between the watch strap and the watch case. It can limit the rotation of the limiting seat through a limiting surface and a limiting protrusion, and can suppress the upward flipping movement of the watch strap through a limiting pressure plate, preventing the watch strap from flipping up and improving the wearing stability and overall aesthetics of the watch. Secondly, the carrier and the limiting seat are assembled by a rotating connection, allowing the carrier to drive the watch strap to rotate flexibly, thereby reducing the difficulty of wearing the watch and improving wearing comfort. Furthermore, this connection structure can effectively limit the rotational stroke of the carrier, preventing excessive compression of the watch strap and ensuring sufficient movement of the watch strap during wear.

[0040] Additionally, it should be noted that the connecting spring bar and the assembling spring bar described in this embodiment are common connecting components in the field of watch parts. When manufacturing watch products using the strap-case connection structure provided in this embodiment, two sets of this connection structure should be provided on both sides of the watch case to facilitate the simultaneous connection of two straps on the watch.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
