Description
Technical Field
[0001] This invention belongs to the field of watch accessory technology, and in particular relates to a press-type quick-release structure for watch cases. Background Technology
[0002] A watch typically consists of core components such as a case, movement, dial, and strap. The case serves as the base that carries and protects the intricate internal movement, and it has opposing lugs on both sides. The strap is attached to the lugs on the case via connecting structures at its ends, thus forming a shape that wraps around the wrist.
[0003] In existing technology, the connection between the watch strap and the watch case is generally achieved using spring bars. The spring bar has an internal spring mechanism and retractable protrusions at both ends. During installation, the worker first needs to install the spring bar at the end of the watch strap, and then use tools to overcome the resistance of the spring mechanism, thereby inserting the protrusions of the spring bar into the holes of the connecting lugs. Similarly, tools are also required to separate the watch strap from the watch case during disassembly.
[0004] However, in practical applications, the disassembly and assembly of the spring bar requires specialized tools and a high level of skill, increasing the difficulty for ordinary users. Attempting to disassemble or assemble the watch by hand without the necessary tools can damage the watch case or strap, resulting in unnecessary losses. Summary of the Invention
[0005] In view of this, the present invention aims to provide a press-type shell with quick-release structure to solve the above-mentioned technical problems.
[0006] To achieve the above objectives, the technical solution created by this invention is implemented as follows: A press-type quick-release watch strap structure includes: a connecting lug, a connecting ear, and a locking assembly. One end of the connecting lug is connected to the end of the watch strap, and the other end of the connecting lug has a splicing portion. One end of the connecting ear is connected to the watch case, and the other end of the connecting ear has a mounting groove for accommodating the splicing portion. A guide hole is provided on the side wall of the connecting ear, and the guide hole communicates with the mounting groove. The locking assembly includes a locking pin, which is slidably disposed inside the guide hole. A locking head is provided at one end of the locking pin, and the locking head is located inside the mounting groove, with an outer diameter larger than the outer diameter of the locking pin. The splicing portion has a locking hole for accommodating the locking head, and the end of the splicing portion away from the connecting lug has a disassembly cut, which communicates with the locking hole. The width of the disassembly cut is greater than the outer diameter of the locking pin and smaller than the outer diameter of the locking head.
[0007] Furthermore, the inner wall of the assembly groove is provided with a clearance groove for accommodating the locking head, and the clearance groove is aligned with the guide hole.
[0008] Furthermore, when the splicing part is inserted into the assembly groove, the side wall of the splicing part away from the guide hole contacts the inner wall of the assembly groove which has a relief groove. Along the sliding direction of the locking pin, the length of the relief groove is not less than the length of the locking head, and a part of the locking head is located inside the locking hole, while the other part of the locking head is located inside the relief groove.
[0009] Furthermore, the locking assembly includes a spring sleeved on the locking pin. A pressing head is provided at the end of the locking pin away from the locking head. The pressing head is located outside the connecting lug, and the outer diameter of the pressing head is larger than the outer diameter of the locking pin. The guide hole includes a guide section for accommodating the locking pin and an assembly section for accommodating the pressing head. The assembly section is located at the end of the guide section away from the assembly groove. The spring is located inside the assembly section, with one end of the spring abutting against the inner wall of the assembly section and the other end of the spring abutting against the pressing head.
[0010] Furthermore, the pressing head is provided with a receiving ring groove for accommodating the end of the spring.
[0011] Furthermore, the locking assembly includes a limiting member, which is detachably mounted on the locking pin. The limiting member is located inside the assembly groove, and the outer diameter of the limiting member is larger than the inner diameter of the guide hole.
[0012] Furthermore, the locking pin is provided with a positioning ring groove, and at least a portion of the limiting member is located inside the positioning ring groove.
[0013] Furthermore, the splicing part is provided with a clearance groove for accommodating the limiting member. The clearance groove is located at one end of the locking hole near the guide hole, and both the locking hole and the disassembly cut are connected to the clearance groove.
[0014] Furthermore, the locking head has a first guide cone surface at its end edge away from the locking pin, and a second guide cone surface at its end edge near the locking pin.
[0015] Furthermore, the end edge of the splicing part away from the connecting head is provided with a third guide cone surface, and the end edge of the locking hole away from the guide hole is provided with a fourth guide cone surface.
[0016] Compared with existing technologies, the press-type shell with quick-release structure described in this invention has the following advantages: This invention provides a press-type quick-release structure for watch straps, where the connecting links and lugs can be quickly and easily disassembled and installed via a locking assembly, simplifying the process of assembling and disassembling the watch strap and case without the need for specialized tools. When the insert is inserted into the mounting slot, the locking pin can enter the locking hole along the disassembly / assembly cut, and the locking head can enter the locking hole, enabling quick installation of the connecting links and lugs. When disassembling the watch strap from the case, the user can press to slide the locking pin, causing the locking head to disengage from the locking hole and pulling the connecting link outwards, thus disengaging the locking pin along the disassembly / assembly cut and easily completing the disassembly.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0022] The invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0023] This embodiment provides a press-type quick-release structure for watch straps, which enables quick assembly and disassembly of the watch strap and watch case. Figures 1-8The diagram shows a push-button quick-release mechanism for the watch strap. As shown, the mechanism includes a connecting lug 1, a connecting ear 2, and a locking assembly. One end of the connecting lug 1 is connected to the end of the watch strap, and the other end has a connecting portion 4. One end of the connecting ear 2 is connected to the watch case 3, and the other end has a mounting groove 21 for accommodating the connecting portion 4. In use, the user inserts the connecting portion 4 into the mounting groove 21, establishing the connection between the connecting lug 1 and the connecting ear 2, thus completing the installation of the watch strap and the watch case 3.
[0024] Specifically, the locking assembly in this embodiment includes a locking pin 5, with a locking head 51 at one end of the locking pin 5, and the outer diameter of the locking head 51 being larger than the outer diameter of the locking pin 5. To facilitate the installation and application of the locking assembly, a guide hole 22 is provided on the side wall of the connecting lug 2, and the guide hole 22 communicates with the assembly groove 21. The splicing part 4 has a locking hole 41 for accommodating the locking head 51. A disassembly / removal cut 42 is also provided at the end of the splicing part 4 away from the connecting head piece 1, and the disassembly / removal cut 42 communicates with the locking hole 41. The width of the disassembly / removal cut 42 is larger than the outer diameter of the locking pin 5 and smaller than the outer diameter of the locking head 51. After assembly, the locking pin 5 is slidably disposed inside the guide hole 22, and the locking head 51 is located inside the assembly groove 21. When assembly is required, the user inserts the splicing part 4 into the assembly slot 21, and then drives the locking pin 5 to slide into the assembly slot 21 so that the locking pin 5 is aligned with the disassembly cut 42 and enters the locking hole 41 along the disassembly cut 42. Next, the user drives the locking pin 5 to slide in the opposite direction so that the locking head 51 enters the locking hole 41. Figure 3 As shown, since the width of the disassembly cut 42 is smaller than the outer diameter of the locking head 51, when the locking head 51 is located inside the locking hole 41, the locking head 51 cannot pass through the disassembly cut 42. This ensures a reliable limiting and fixing effect between the splicing part 4 and the assembly groove 21, realizing the assembly of the connecting head 1 and the connecting ear 2. When disassembly is required, the user can first slide the locking pin 5 into the assembly groove 21 to disengage the locking head 51 from the locking hole 41, forming a... Figure 4 The structure is shown. Next, pull the connecting head 1 outward to disengage the locking pin 5 from the locking hole 41 along the disassembly cut 42, and finally disengage the splicing part 4 from the assembly groove 21, completing the disassembly of the connecting head 1 and the connecting ear 2.
[0025] Optionally, to improve ease of operation, the locking assembly may include a spring 6, and the end of the locking pin 5 away from the locking head 51 may be provided with a pressing head 52, with the outer diameter of the pressing head 52 being larger than the outer diameter of the locking pin 5. Correspondingly, the guide hole 22 may include a guide section 221 for accommodating the locking pin 5 and an assembly section 222 for accommodating the pressing head 52, with the assembly section 222 located at the end of the guide section 221 away from the assembly groove 21. During assembly, the pressing head 52 is located outside the connecting lug 2, the spring 6 is sleeved on the locking pin 5, and the spring 6 is located inside the assembly section 222, with one end of the spring 6 abutting against the inner wall of the assembly section 222 and the other end abutting against the pressing head 52. Figure 3 In the state shown, spring 6 is in a pre-compressed state, so the elastic force of spring 6 ensures that the locking head 51 reliably remains inside the locking hole 41. When the user applies a pressing force to the pressing head 52, it drives the locking pin 5 to slide, thereby forming the locking position as shown. Figure 4 The state shown facilitates the separation of the connecting head 1 from the connecting ear 2. When the user removes the pressing force, the elastic force of the spring 6 can reset the locking pin 5 for subsequent use.
[0026] As an optional embodiment of this invention, the pressing head 52 may be provided with a receiving annular groove 521 for accommodating the end of the spring 6. The receiving annular groove 521 can position the end of the spring 6, preventing the spring 6 from shifting or tilting during compression and extension, and ensuring the smooth sliding of the locking pin 5.
[0027] It should be noted that, in order to facilitate the installation of the locking pin 5, the inner diameter of the guide section 221 in this embodiment should not be less than the outer diameter of the locking head 51, so that the workers can insert the locking head 51 into the assembly groove 21 along the guide hole 22.
[0028] To improve the assembly reliability between the interlocking part 4 and the assembly groove 21, and to ensure that the locking head 51 can smoothly disengage from the locking hole 41 during disassembly, this embodiment provides a relief groove 23 on the inner wall of the assembly groove 21 to accommodate the locking head 51, and the relief groove 23 is aligned with the guide hole 22. When the interlocking part 4 is inserted into the assembly groove 21, the side wall of the interlocking part 4 away from the guide hole 22 will contact the inner wall of the assembly groove 21 with the relief groove 23, thereby increasing the contact area between the interlocking part 4 and the inner wall of the assembly groove 21 and enhancing assembly stability. At the same time, along the sliding direction of the locking pin 5, the length of the relief groove 23 is not less than the length of the locking head 51, and after the connecting head 1 and the connecting ear 2 are assembled, a part of the locking head 51 should be located inside the locking hole 41, and the other part of the locking head 51 should be located inside the relief groove 23. The presence of the clearance groove 23 provides clearance space for the locking head 51, making it easier for the locking head 51 to disengage from the locking hole 41 during assembly and disassembly. In addition, since the locking head 51 will be located in both the locking hole 41 and the clearance groove 23 after the connecting head 1 and the connecting ear 2 are assembled, the locking contact area can be increased, thus improving the reliability of the assembly.
[0029] As another optional implementation of this embodiment, to improve the smoothness of the locking head 51's movement, a first guide cone surface 511 may be provided on the end edge of the locking head 51 away from the locking pin 5, and a second guide cone surface 512 may be provided on the end edge of the locking head 51 near the locking pin 5. The first guide cone surface 511 facilitates the locking head 51's entry into the clearance groove 23, while the second guide cone surface 512 facilitates the locking head 51's entry into the locking hole 41, thereby effectively reducing the jamming sensation of the locking head 51's movement. Furthermore, a third guide cone surface 44 may be provided on the end edge of the interlocking part 4 away from the connecting head 1, and a fourth guide cone surface 411 may be provided on the end edge of the locking hole 41 away from the guide hole 22. When the splicing part 4 is provided with a third guide cone surface 44, the process of inserting the splicing part 4 into the assembly groove 21 allows the third guide cone surface 44 to come into contact with the second guide cone surface 512. This, in turn, drives the locking pin 5 to slide, improving the smoothness of the insertion of the splicing part 4. After the locking pin 5 smoothly enters the locking hole 41 along the disassembly cut 42, the fourth guide cone surface 411 can also cooperate with the second guide cone surface 512, further improving the smoothness of the locking head 51 entering the locking hole 41.
[0030] To prevent the locking pin 5 from disengaging from the guide hole 22, the locking assembly in this embodiment may further include a limiting member 7. Specifically, the limiting member 7 is detachably mounted on the locking pin 5, and the outer diameter of the limiting member 7 should be larger than the inner diameter of the guide hole 22. After installation, the limiting member 7 should be located inside the assembly groove 21, at which point the limiting member 7 can form a limiting stop with the inner wall of the assembly groove 21, preventing the locking pin 5 from disengaging from the guide hole 22.
[0031] Secondly, to prevent the limiting member 7 from axially moving on the locking pin 5, the locking pin 5 can also be provided with a positioning ring groove 53. During assembly, at least a portion of the limiting member 7 should be located inside the positioning ring groove 53, thereby effectively fixing the limiting member 7. For example, the limiting member 7 provided in this embodiment can be an E-type retaining ring or an open retaining ring. During installation, the operator can insert the limiting member 7 into the positioning ring groove 53 to achieve a stable connection between the limiting member 7 and the locking pin 5.
[0032] In addition, to avoid interference between the limiting member 7 and the interlocking part 4, the interlocking part 4 may also be provided with a clearance groove 43 for accommodating the limiting member 7. The clearance groove 43 is located at the end of the locking hole 41 near the guide hole 22, and both the locking hole 41 and the disassembly cut 42 are connected to the clearance groove 43. When the interlocking part 4 is inserted into the assembly slot 21, the limiting member 7 can enter the clearance groove 43, thereby not affecting the insertion of the interlocking part 4 into place.
[0033] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
