[0023] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] As Figure 1As shown in the figure, it is a schematic structural diagram of a quick-release structure for connecting a watchband to a watch case provided by an embodiment of the present invention. This quick-release structure for connecting a watchband to a watch case can be applied to the technical field of watch products, and can quickly and efficiently realize the disassembly and assembly of the watchband 3 and the watch case 1, while avoiding damage caused by violent disassembly and assembly.

[0025] Combined with Figure 2 As shown in the figure, the quick-release structure for connecting a watchband to a watch case in this embodiment includes a groove 11 provided in the watch case 1, a card slot 12 provided on the side wall of the groove 11, and a quick-release component 2 detachably assembled into the groove 11. The opening of the groove 11 is located at the edge of the bottom surface of the watch case 1. This is beneficial for locking the watchband 3 on the edge of the watch case 1 through the quick-release component 2, and can also hide the groove 11 and the quick-release component 2, which is both beautiful and can prevent the quick-release component 2 from being easily touched or impacted, resulting in misoperation or damage.

[0026] Combined with Figure 3 and Figure 4 As shown in the figure, the above-mentioned quick-release component 2 includes a connection seat 21, an elastic member 22, and a locking member 23. The connection seat 21 includes a watchband connection portion 211 for connecting the watchband 3 and a watch case connection portion 212 for being assembled into the watch case 1 through the opening of the groove 11. That is, the watch case connection portion 212 can be assembled into the groove 11 through the opening of the groove 11, so as to realize the detachable connection with the watch case 1. In this way, the connection seat 21 can specifically connect the watchband 3 through the watchband connection portion 211 and connect the watch case 1 through the watch case connection portion 212, so as to realize the connection between the watchband 3 and the watch case 1. The above-mentioned watch case connection portion 212 is preferably adapted to the groove 11 to prevent the watch case connection portion 212 from easily moving in the groove 11. For example, both ends of the watch case connection portion 212 in the width direction of the watch case 1 (the length direction of the watch case 1 is the arrangement direction of the two ends connected to the watchband 3, specifically the length direction of the watchband 3) are connected to the two ends of the groove 11 respectively, so as to limit the watchband connection portion 211 and prevent the watchband connection portion 211 from moving in the width direction of the watch case 1, improving the installation stability and reliability of the connection seat 21.

[0027] Furthermore, the above-mentioned locking member 23 includes a driving portion and a buckle portion adapted to the card slot 12. When the watch case connection portion 212 is assembled into the groove 11, the locking member 23 is slidably connected to the connection seat 21 with the buckle portion facing the side wall where the card slot 12 is located, ensuring that the locking member 23 can make the buckle portion snap into the card slot 12 through sliding to realize the buckling function. And, the above-mentioned elastic member 22 is located between the watch case connection portion 212 of the connection seat 21 and the locking member 23. In this way, the locking member 23 will make the buckle portion snap into the card slot 12 under the drive of the elastic member 22, so as to lock the watch case connection portion 212 of the connection seat 21 in the groove 11, preventing the quick-release component 2 from disengaging from the groove 11 and realizing the locking function.

[0028] Specifically, at least a part of the above-mentioned driving part is located at the opening of the groove 11, which facilitates the pushing and driving of the driving part and improves the convenience of the unlocking operation. During the unlocking operation, when the driving part is pushed, the locking part 23 will slide on the connecting seat 21 and squeeze the elastic part 22, causing the elastic part 22 to undergo elastic deformation. At the same time, the locking part 23 drives the buckle part to disengage from the clamping groove 12, and thus the connecting seat 21 can be taken out of the groove 11, that is, the watch case connecting part 212 of the connecting seat 21 disengages from the groove 11, realizing the disassembly operation of the watch band 3 and the watch case 1. Since the elastic part 22 undergoes elastic deformation, when the driving force is released, the locking part 23 will slide on the connecting seat 21 under the driving of the elastic restoring force of the elastic part 22, thereby driving the buckle part to be clamped into the clamping groove 12, realizing the assembly and locking operation of the watch band 3 and the watch case 1.

[0029] The above-mentioned quick-release structure for connecting the watch band to the watch case realizes the quick-release connection of the watch band 3 and the watch case 1 by setting up the quick-release component 2, and connecting the watch band 3 through the quick-release component 2. In this way, when the quick-release component 2 is assembled into the clamping groove 12 and the buckle part is clamped into the clamping groove 12, the quick-release connection can be achieved. When unlocking, only the driving part needs to be pushed, which greatly reduces the disassembly and assembly difficulty, is simple and convenient to operate, does not require tools, avoids scratching the watch band 3 and the watch case 1, and there is no problem of the pin shaft falling off, with high practicality.

[0030] On the side wall of the above-mentioned groove 11 facing away from the main body of the watch case 1, there is an avoidance groove 13 communicating with the end face of the watch case 1, that is, the avoidance groove 13 is located on the side wall of the groove 11 close to the watch band 3. To improve the rationality of the structural design, the avoidance groove 13 is located in the center of the side wall of the groove 11, and the avoidance groove 13 communicates with the opening of the groove 11.

[0031] Specifically, the above-mentioned connecting seat 21 includes a transition connecting part 213. The watch band connecting part 211 is fixedly connected to the watch case connecting part 212 through the transition connecting part 213, that is, the transition connecting part 213 is connected between the watch band connecting part 211 and the watch case connecting part 212. In this way, when the watch case connection is assembled into the groove 11, the transition connecting part 213 can be embedded in the avoidance groove 13, so that the watch band connecting part 211 is located on the end face of the watch case 1 (since the avoidance groove 13 communicates with the end face of the watch case 1, the watch band connecting part 211 will be located outside the end of the watch case 1), and further the watch band 3 can be connected to the end of the watch case 1, ensuring that the watch case 1 can be tightened on the wrist through the watch band 3, and avoiding the watch band 3 being located on the bottom surface of the watch case 1 and affecting the wearing.

[0032] Combined with Figure 5As shown in the figure, the above-mentioned locking fastener 23 includes a sliding body 231 in a convex shape, two protruding hooks 232 protruding from the lower surface of the sliding body 231, and a protruding pattern 233 provided on the upper surface of the sliding body 231. The driving part is constituted by the protruding pattern 233, and the protruding pattern 233 can play an anti-slip role, so as to improve the reliability of the driving operation of the driving part. In addition, the buckling part is constituted by two protruding hooks 232. When the quick-release assembly 2 is assembled into the groove 11, the two protruding hooks 232 are respectively located on both sides of the transition connecting part 213, so that the locking fastener 23 can be initially positioned, preventing the locking fastener 23 from moving left and right within a large range on the connecting seat 21. And the two protruding hooks 232 are respectively arranged on both sides of the transition connecting part 213, which can make the force received by the buckling part and the card slot 12 more uniform, so that the clamping connection between the quick-release assembly 2 and the watch case 1 is more firm and reliable.

[0033] Particularly, when the quick-release assembly 2 is assembled into the groove 11, at least a part of the convex end of the sliding body 231 is embedded in the avoidance groove 13. Since the sliding body 231 is in a convex shape and at least a part of the convex end of the sliding body 231 is embedded in the avoidance groove 13, this can not only effectively increase the plane area of the sliding body 231, which is beneficial to the setting of the protruding pattern 233 and improves the operability of driving the locking fastener 23, but also can block the connecting seat 21 by the locking fastener 23, which is both beautiful and can prevent external dust and foreign objects from easily entering the groove 11. And, the protruding pattern 233 is flush with or lower than the bottom surface of the watch case 1, so that it is not easy to touch the protruding pattern 233, reducing the possibility of misoperation of the driving part.

[0034] In an embodiment of the present invention, the above-mentioned groove 11 is square, and the length direction of the groove 11 is perpendicular to the length direction of the watch case 1, that is, the groove 11 is arranged horizontally, which is beneficial to improving the space utilization rate of the outer edge of the watch case 1 and preventing the volume of the two ends of the watch case 1 connected to the watch from increasing. Particularly, the above-mentioned card slot 12 and the avoidance groove 13 are both located on the same side wall in the width direction of the groove 11. When the quick-release assembly 2 is assembled into the groove 11, the locking fastener 23 is driven by the elastic member 22 to slide along the length direction perpendicular to the card slot 12, that is, the locking fastener 23 slides along the width direction of the card slot 12 (which is also the length direction of the watch case 1 and the watch band 3), optimizing the unlocking driving direction of the driving part and being beneficial to improving the convenience of the unlocking operation.

[0035] Moreover, the card slot 12 is located on the side of the groove 11 close to the watch band 3, so that the locking member 23 will move under the drive of the elastic member 22 to make the buckle portion snap into the card slot 12. At the same time, the watch case connecting portion 212 of the connecting seat 21 will receive the elastic force of the elastic member 22 in the direction away from the watch band 3, thereby preventing the watch band connecting portion 211 from moving in the groove 11 in the direction of the watch band connecting portion 211, and further reliably limiting the watch band connecting portion 211 at the edge of the watch case 1, so that the watch band 3 can be reliably attached to the outer edge of the watch case 1, avoiding large gaps that are prone to dust accumulation or foreign object entry.

[0036] Preferably, the above-mentioned card slot 12 communicates with the avoidance slot 13 to ensure that the two protruding hooks 232 can be reliably snapped into the cavity of the card slot 12 on both sides of the avoidance slot 13. And the card slot 12 is arranged along the length direction of the groove 11, that is, parallel to the opening direction of the groove 11, which can effectively improve the stability and reliability of the protruding hook 232 being snapped into the card slot 12, and avoid the inclination of the card slot 12 causing the protruding hook 232 to slide in the card slot 12.

[0037] The above-mentioned watch case connecting portion 212 is a cuboid adapted to the groove 11, and the transition connecting portion 213 is connected to the center of one side surface of the watch case connecting portion 212 to optimize the structure, improve the rationality of the structural design, facilitate processing, and the two side surfaces of the transition connecting portion 213 do not protrude from the two end surfaces in the length direction of the watch case 1 to form an avoidance slot. In this way, when the locking member 23 is assembled to the connecting seat 21, the two protruding hooks 232 will be respectively embedded in the avoidance slots on both sides of the transition connecting portion 213, which can play a protective role for the protruding hooks 232, and at the same time improve the smoothness and stability of the protruding hooks 232 moving to lock and unlock.

[0038] Furthermore, two limiting protrusions 215 are provided on the surface of the watch case connecting portion 212 facing away from the groove 11, and when the locking member 23 is assembled to the connecting seat 21, the two limiting protrusions 215 are respectively limited on both sides of the locking member 23 to prevent the locking member 23 from moving in the width direction of the watch case 1, ensuring that the locking member 23 can slide reliably along the length direction of the watch case 1 and the watch, improving the stability and reliability of the sliding of the locking member 23, and ensuring that the buckle portion can be reliably snapped into the card slot 12. In practical applications, sliding grooves 216 are provided on the surfaces of the two limiting protrusions 215 facing each other, sliding protrusions 235 are provided on both sides of the locking member 23, and when the locking member 23 is assembled to the connecting seat 21, the sliding protrusions 235 of the locking member 23 are engaged into the sliding grooves 216.

[0039] The above-mentioned case connection part 212 is provided with a long hole 217 arranged along the length direction of the watch band 3. The locking part 23 is provided with a fixing hole 234 adapted to the long hole 217. The locking part 23 is limited on the connection seat 21 by a bolt 24 passing through the long hole 217 and connecting to the fixing hole 234. In this way, when the locking part 23 slides on the connection seat 21, the bolt 24 will move in the long hole 217, which will not affect the locking operation of the locking part 23. The bolt 24 can also lock and limit the locking part 23 on the connection seat 21, improving the installation stability of the locking part 23 and preventing the locking part 23 from detaching from the connection seat 21 and causing the locking to fail.

[0040] Further, the above-mentioned elastic member 22 includes two compression springs. The surface of the case connection part 212 facing the transition connection part 213 is provided with two first spring holes 214 adapted to the compression springs. The two first spring holes 214 are respectively located on both sides of the transition connection part 213. When the quick-release assembly 2 is assembled into the groove 11, at least a part of the compression spring is embedded in the first spring hole 214. This can effectively improve the installation stability of the compression spring, prevent the compression spring from being deformed by force and causing dislocation, ensure that the compression spring can provide elastic force in the locking direction for the locking part 23, and enable the buckle part to be reliably clamped in the card slot 12. Moreover, the two first spring holes 214 are located on both sides of the transition connection part 213, that is, the two compression springs are located on both sides of the transition connection part 213, which is beneficial to the balanced and uniform force of the locking part 23 and improves the smoothness and stability of the sliding of the locking part 23.

[0041] Of course, in actual application, the surfaces of the two protruding hooks 232 facing away from the hook part (i.e., the surfaces facing the watch band connection part 211) are respectively provided with second spring holes 236 adapted to the compression springs. The end of the compression spring far from the first spring hole 214 is embedded in the second spring hole 236 of the locking part 23. This can enable the compression spring to be reliably connected to the locking part 23 and prevent the compression spring from detaching and causing the clamping failure of the buckle part and the card slot 12.

[0042] The above-mentioned watchband connecting portion 211 is cylindrical, and the watchband connecting portion 211 and the transition connecting portion 213 are connected in a T-shaped arrangement. When connecting the watchband 3 at the connecting portion, the watchband connecting portion 211 is embedded in the head end of the watchband 3, so that the connecting seat 21 can be reliably connected to the watchband 3 through the watchband connecting portion 211. The watchband 3 is preferably made of a plastic material and can be integrally processed onto the watchband connecting portion 211 of the connecting seat 21 through an injection molding process, so that the connection between the watchband connecting portion 211 and the watchband 3 is more firm and reliable. Of course, in practical applications, the structural design of the watchband connecting portion 211 can be specifically determined according to actual situations; for example, the watchband connecting portion 211 includes a pivot hole provided along the width direction, and the watch can be pivotally connected to the pivot hole of the watchband connecting portion 211 through a pivot shaft, which can also effectively improve the designability of the watch material. For example, the watch can be made of materials such as metal, leather or plastic.

[0043] Further, two protruding limiting lugs 31 are provided at the head end of the watchband 3, and two limiting grooves 14 adapted to the limiting lugs 31 are provided at the edge of the bottom surface of the watch case 1. When the quick-release assembly 2 is assembled into the groove 11, the two limiting lugs 31 are snapped into the two limiting grooves 14. The operation is simple and convenient, and the watchband 3 and the watch case 1 are directly connected by the snap connection of the limiting lugs 31 and the limiting grooves 14. This can make the connection between the watchband 3 and the watch case 1 more firm and reliable, enhance the tensile force resistance ability of the watchband 3, and at the same time reduce the force on the quick-release assembly 2, avoid the quick-release assembly 2 being easily damaged by force, and extend the service life of the quick-release assembly 2. In practical applications, there is an angle (such as 30°, 45°, etc.) between the two limiting lugs 31 and the length direction of the watchband 3, which can enable the limiting lugs 31 to be reliably snapped into the limiting grooves 14.

[0044] The embodiment of the present invention also provides a watch, which includes the quick-release structure for connecting the watchband to the watch case as described above.

[0045] As mentioned above, only the preferred specific embodiments of the present invention are described, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
