Description

Technical Field

[0001] This utility model relates to the technical field of watches, and in particular to a watch strap connection structure. Background Technology

[0002] Originally, a watch was a timekeeping instrument worn on the wrist, with only this function. Its structure mainly consisted of a watch head and a strap. With social development and technological advancements, watches have acquired multiple functions such as communication, health monitoring, and photography, becoming an essential item in the lives and work of more and more users. At the same time, users' demand for personalized products is also gradually increasing.

[0003] Currently, watch straps primarily use pin-type and hook-and-loop fasteners for connection. However, both of these methods are quite cumbersome to install and remove, posing a significant challenge for the average user and hindering personalized strap replacement. Furthermore, without specialized tools, improper handling during disassembly can easily damage the strap and the connection to the watch head. Therefore, there is an urgent need to address these issues. Utility Model Content

[0004] To address the aforementioned problems, this utility model achieves the above objectives through the following technical solution: a watch strap connection structure, comprising a watch head and a watch strap, wherein the watch head is provided with a through groove, a mounting hole is provided through one side wall of the through groove, a limiting member is provided at the inner end of the mounting hole, a first stepped surface is recessed at the inner end of the mounting hole, a button is provided at the outer end of the mounting hole to connect with the limiting member, and a second stepped surface is recessed at the outer end of the mounting hole; a baffle is protruding on the limiting member to stop and cooperate with the first stepped surface; a first elastic member is provided between the button and the second stepped surface, the first elastic member always having a tendency to let the baffle abut against the first stepped surface, so that the inner end of the mounting hole always has a connection gap;

[0005] The end of the watch strap is provided with a limiting strip that engages with the through slot. The limiting strip is provided with a locking member that can be engaged into the connection gap. The limiting strip has an assembly hole. The locking member is located at one end of the assembly hole. The other end of the assembly hole is provided with a pushing block connected to the locking member. A second elastic member is provided between the locking member and the pushing block. The second elastic member always tends to keep the locking member away from the pushing block. A limiting plate is provided in the middle of the assembly hole. A third elastic member is provided between the limiting plate and the pushing block. The third elastic member always tends to keep one end of the pushing block protruding outside the assembly hole.

[0006] Furthermore, the width of the through groove gradually decreases from the bottom to the opening to achieve a snap-fit ​​connection between the through groove and the limiting strip, ensuring a secure connection.

[0007] Furthermore, the limiting member is provided with a first slot, and the button is provided with a first buckle that matches the first slot; this facilitates the connection between the limiting member and the button, ensuring a secure connection and easy assembly.

[0008] Furthermore, the button has a protruding connecting post, and one end of the first elastic element is sleeved on the connecting post; this facilitates the installation of the first elastic element and ensures stable and reliable force application.

[0009] Furthermore, the locking member is provided with a second slot, and the pushing block is provided with a second buckle that matches the second slot; this facilitates the connection between the locking member and the pushing member, ensuring a secure connection and easy assembly.

[0010] Furthermore, the outer end face of the push block is an arc surface; when the watch strap is inserted into the limiting strip, the push block can overcome the elastic force of the third elastic element and push the locking element into the connection gap, making the connection secure.

[0011] Furthermore, through holes are provided at both ends of the assembly hole, and balance blocks are engaged in the through holes.

[0012] Compared with the prior art, the advantages of this utility model are as follows: Firstly, when assembling the watch strap, simply insert the limiting strip into the through groove. When the locking member reaches the connection gap, it will engage, thus locking the watch strap to the watch head for quick assembly. Secondly, when disassembling the watch strap, simply push the button with external force to overcome the elastic force of the first elastic element, causing the baffle on the limiting member to move away from the first step surface. The limiting member then pushes the locking member, causing it to disengage from the connection gap and release the lock. At this point, the limiting strip can slide out along the through groove to complete the disassembly. Throughout the entire assembly and disassembly process, the user does not need any other tools. Firstly, the watch strap can be easily disassembled and reassembled, making the operation relatively simple and quick, facilitating personalized replacement without damaging the structure of the watch strap and the connection point between the watch head and the watch. Secondly, with the reliable connection of the limiting component and the button, as well as the stop cooperation between the baffle and the first step surface, the button can be reliably connected to the watch head and will not fall off, thus solving the technical problems in the prior art. Overall, this utility model has the advantages of simple structure, convenient disassembly and assembly, and reliable connection, making it convenient for users to replace the watch strap, effectively reducing the difficulty of disassembly and assembly, and avoiding the problem of damage to the product during disassembly and assembly.

[0020] like Figures 1 to 4 As shown, this utility model provides a watch strap connection structure, including a watch head 1 and a watch strap 2. The watch head 1 is provided with a through groove 1.1, and a mounting hole 1.2 is provided through one side wall of the through groove 1.1. A limiting member 3 is provided at the inner end of the mounting hole 1.2, and a first stepped surface 1.3 is recessed at the inner end of the mounting hole 1.2. A button 4 connected to the limiting member 3 is provided at the outer end of the mounting hole 1.2, and a second stepped surface 1.4 is recessed at the outer end of the mounting hole 1.2. A baffle 3.1 is protruding on the limiting member 3 and cooperates with the first stepped surface 1.3. A first elastic member 5 is provided between the button 4 and the second stepped surface 1.4. The first elastic member 5 always tends to make the baffle 3.1 abut against the first stepped surface 1.3, so that the inner end of the mounting hole 1.2 always has a connection gap 6.

[0021] The end of the watch strap 2 is provided with a limiting strip 2.1 that engages with the through groove 1.1. The limiting strip 2.1 is provided with a locking element 7 that can be inserted into the connecting gap 6. The limiting strip 2.1 is manufactured as an integral part of the watch strap 2.

[0022] refer to Figure 4 As shown, the width of the through groove 1.1 gradually decreases from the bottom to the opening. The outer end face of the button 4 is flush with the surface of the meter head 1 or has a small protrusion, so as not to obstruct the user's view and to improve wearing comfort.

[0023] The limiting component 3 has a first slot 3.2, and the button 4 has a first buckle 4.1 that matches the first slot 3.2. Specifically, the first buckle 4.1 is made of elastic steel sheet, and the limiting component 3 is also made of steel, which can effectively ensure a reliable connection, extend service life, and make it more durable. The bottom of the button 4 has two symmetrically protruding first buckles 4.1, and the limiting component 3 has two corresponding first slots 3.2, so that both sides are locked together, making the connection more reliable and stable. Of course, more first buckles 4.1 and first slots 3.2 can be set according to actual needs to ensure the reliability of the connection.

[0024] refer to Figure 3 As shown, a connecting post 4.2 protrudes from the button 4, and one end of the first elastic member 5 is sleeved on the connecting post 4.2.

[0025] A mounting hole 2.2 is provided on the limiting strip 2.1. A locking member 7 is disposed at one end of the mounting hole 2.2, and a pushing block 8 connected to the locking member 7 is provided at the other end of the mounting hole 2.2. A second elastic member 9 is provided between the locking member 7 and the pushing block 8. The second elastic member 9 always tends to keep the locking member 7 away from the pushing block 8. A limiting plate 2.3 is provided in the middle of the mounting hole 2.2. A third elastic member 10 is provided between the limiting plate 2.3 and the pushing block 8. The third elastic member 10 always allows one end of the pushing block 8 to protrude outside the mounting hole 2.2. Specifically, a first clearance hole 2.5 is provided on the limiting plate 2.3 to allow the second elastic member 9 to pass through, ensuring that both ends of the second elastic member 9 abut against the pushing block 8 and the locking member 7 respectively, so as to provide sufficient driving force. A second clearance hole 2.6 is also provided on the limiting plate 2.3 to allow the second buckle 8.1 to pass through, ensuring that the pushing block 8 and the locking member 7 can be connected, making the connection secure.

[0026] The locking element 7 has a second slot 7.1, and the pushing block 8 has a second latch 8.1 that matches the second slot 7.1. Specifically, the second latch 8.1 is made of elastic steel sheet, and the locking element 7 is also made of steel, which can effectively ensure a reliable connection, extend service life, and make it more durable. The bottom of the pushing block 8 has two symmetrically protruding second latches 8.1, and the locking element 7 has two corresponding second slots 7.1, so that both sides are locked together, making the connection more reliable and stable. Of course, more second latches 8.1 and second slots 7.1 can be set according to actual needs to ensure the reliability of the connection. The pushing block 8 can also be provided with connecting posts (not shown in the figure) to facilitate the connection of the second elastic element 9 and the third elastic element 10. The first elastic element 5, the second elastic element 9, and the third elastic element 10 are preferably made of columnar springs.

[0027] The outer end face of the push block 8 is an arc surface. Specifically, the height of the outer edge of the outer end face of the push block 8 is flush with or lower than the surface of the watch strap 2, so that when the limiting strip 2.1 is inserted into the through groove 1.1, it will not be blocked and can be inserted smoothly. With the action of the arc surface and the cooperation of the through groove 1.1, the push block 8 can be pushed to move into the mounting hole 2.2 to compress the second elastic member 9 and the third elastic member 10, and then the locking member 7 can be pushed into the connecting gap 6.

[0028] Through holes 2.4 are provided at both ends of the mounting hole 2.2, and a balance block 11 is snapped into the through hole 2.4; the balance block 11 ensures that the two ends of the watch strap 2 are relatively balanced.

[0029] The working principle of this utility model is as follows: When assembling the watch strap 2 onto the watch head 1, simply slide the limiting strip 2.1 along the through groove 1.1. Before the locking member 7 reaches the connecting gap 6, the pushing block 8 is pushed to the assembly hole 2.2 by the side wall of the through groove 1.1, keeping the second elastic member 9 and the third elastic member 10 compressed (see above for details, not repeated here). Continue to slide the limiting strip 2.1 along the through groove 1.1 until the locking member 7 reaches the connecting gap 6. Under the force of the second elastic member 9 and the third elastic member 10, the locking member 7 will be engaged in the connecting gap 6, thereby locking the watch strap 2 onto the watch head 1, achieving quick assembly (see reference). Figure 1 and Figure 4 (as shown)

[0030] When removing the watch strap 2 from the watch head 1, simply push the button 4 with external force to overcome the elastic force of the first elastic element 5, allowing the baffle 3.1 on the limiting element 3 to move away from the first step surface 1.3. The limiting element 3 then pushes the locking element 7, which disengages from the connection gap 6 to release the lock. At this point, the limiting strip 2.1 slides out along the through groove 1.1, and the disassembly is complete. Throughout the entire disassembly and assembly process, the user can complete the disassembly and assembly without the aid of other tools. The operation is relatively simple and quick, facilitating personalized replacement of the watch strap, and will not damage the structure of the watch strap and the connection point of the watch head.

[0031] In summary, the technical solution of this utility model can fully and effectively achieve the aforementioned objectives. Furthermore, the structure and functional principles of this utility model have been fully verified in the embodiments, achieving the expected effects and objectives. Without departing from the principles and essence of this utility model, various changes or modifications can be made to the embodiments. Therefore, this utility model includes all substitutions within the scope mentioned in the patent application claims, and any equivalent changes made within the scope of this patent application are within the scope of the patent application.
