[0021] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0022] The utility model discloses an easy-to-detach watchband connection structure. Figures 1 to 5As shown, it includes a watch case 1, a watch strap 2 and a fixing buckle 3. A lateral socket 10 is provided on the side of the watch case 1, and a bottom socket 19 is provided on the bottom of the watch case 1. The lateral socket 10 and the bottom socket 19 are communicated with each other. A plug 20 is provided at the end of the watch strap 2, and an L-shaped buckle head 21 bent upward is provided at the end of the plug 20. The plug 20 is inserted into the lateral socket 10, and the L-shaped buckle head 21 is aligned with the bottom socket 19. A strip slot 30 is provided on the fixing buckle 3, and the fixing buckle 3 is inserted into the bottom socket 19. The L-shaped buckle head 21 passes through the strip slot 30 and the two are engaged with each other.

[0023] In the above structure, the end of the strap 2 is provided with a plug 20, and a lateral socket 10 is correspondingly opened on the side of the watch case 1, and the fixing buckle 3 is inserted into the bottom socket 19 of the watch case 1. Based on the snap-fit ​​relationship between the L-shaped buckle head 21 and the strip slot 30, the end of the strap 2 is snap-fitted to the watch case 1, thereby achieving a reliable connection. When disassembling, it is only necessary to overcome the snap-fit ​​stress between the L-shaped buckle head 21 and the strip slot 30, pry the fixing buckle 3 out of the bottom socket 19 or pull the plug 20 out of the lateral socket 10. The disassembly process is simple and convenient, and better meets the needs of users.

[0024] In this embodiment, a strap head 22 is provided at the end of the strap 2 , and the plug 20 and the strap head 22 are integrally formed.

[0025] Furthermore, a connector 23 is formed at one end of the strap head 22 away from the plug 20, and a connecting groove 24 is formed on the end surface of the strap 2, and the connector 23 is inserted into the connecting groove 24 and the two are bonded and fixed.

[0026] In the above structure, this embodiment preferably adopts the method of assembling the strap head 22 and the strap 2 with each other, and the two can be connected by gluing, hot melting, welding, etc. However, in practical applications, it is not limited to this, that is, the strap head 22 and the strap 2 can also be an integral structure. For example, in other embodiments of the utility model, the strap head 22 and the strap 2 are integrally injection molded by plastic material. Among them, the strap 2, the strap head 22, the plug 20, and the L-shaped buckle 21 are all integrally injection molded by this plastic material. This plastic material should have sufficient hardness and a certain elasticity, so as to achieve the requirements of deformation and surrounding of the strap and elastic clamping of the L-shaped buckle 21, and sufficient hardness can ensure that the strap has sufficient force strength and the clamping force of the L-shaped buckle 21 is sufficient, so as to meet the assembly requirements.

[0027] In order to improve the aesthetics of the connection and improve the connection reliability, in this embodiment, the end of the strap head 22 needs to be hidden. Figure 1 , Figure 2 and Figure 5 As shown, a step opening 11 is opened on the side of the watch case 1 , the lateral insertion opening 10 is located in the step opening 11 , and the end of the watch strap head 22 is inserted in the step opening 11 .

[0028] As a preferred method, combined with Figure 2 and Figure 3 As shown, two positioning pins 25 are formed at the end of the strap head 22, and two positioning holes 12 are formed in the step opening 11. The positioning pins 25 are aligned one by one with the positioning holes 12 and the two are plugged in and matched.

[0029] In the above structure, based on the plug-in positioning relationship between the two positioning pins 25 and the two positioning holes 12, the strap head 22 can be reliably positioned within the step opening 11, avoiding misalignment of the strap head 22, and helping to connect the watch case 1 and the strap 2 more tightly.

[0030] Regarding the preferred fixing method of the fixing buckle 3, Figure 1 , Figure 2 and Figure 4 As shown, a back shell 4 is fixed to the back side of the watch case 1, a strip-shaped through hole 40 is opened on the back shell 4, a protrusion 31 is formed on the outer side of the fixing buckle 3, the fixing buckle 3 is clamped on the inner side of the back shell 4, and the protrusion 31 is passed through the strip-shaped through hole 40.

[0031] In the above structure, the back shell 4 can cover and be clamped on the fixing buckle 3, so as to restrict the fixing buckle 3 in the bottom socket 19, and at the same time allow the protrusion 31 to pass through the strip-shaped through hole 40. The fixing buckle 3 in this embodiment can be made of the same plastic material as the strap 2, so that the fixing buckle 3 also has a certain elasticity, which is convenient for it to be clamped with the L-shaped buckle head 21.

[0032] As a preferred embodiment, the surface of the protrusion 31 is flush with the surface of the back shell 4. The structure in which the two are flush with each other can avoid dirt from being hidden and improve the aesthetics of the back surface.

[0033] For the preferred structure of the fixing buckle 3, please refer to Figure 4 The fixing buckle 3 includes two vertical arms 32 , a cross beam 33 is connected between the two vertical arms 32 , and the fixing buckle 3 , the two vertical arms 32 and the cross beam 33 together form the strip-shaped slot 30 .

[0034] Furthermore, a wedge-shaped portion 34 is formed on one side of the cross beam 33 facing the lateral socket 10 .

[0035] In this embodiment, there are two ways to connect the strap 2. One is to first insert the fixing buckle 3 into the bottom socket 19, then align the L-shaped buckle head 21 with the strip slot 30, and then push the strap 2 toward the watch case 1 to make the L-shaped buckle head 21 slide along the wedge-shaped portion 34 until the L-shaped buckle head 21 passes through the strip slot 30 and is hooked with the crossbeam 33. Figure 3 As shown;

[0036] Another connection method is to first insert the plug 20 into the side socket 10, and then insert the fixing buckle 3 into the bottom socket 19. Because the fixing buckle 3 and the L-shaped buckle head 21 are both elastic plastic parts, during the process of inserting the fixing buckle 3, the fixing buckle 3 and the L-shaped buckle head 21 are squeezed and deformed until the crossbeam 33 passes over the L-shaped buckle head 21 and the L-shaped buckle head 21 passes through the strip slot 30, thereby completing the assembly.

[0037] The assembly process of the above structure is simple and convenient, and does not rely on spring ears or screws for fixing. There is no problem of rust on metal parts, and it can also meet the user's application needs of flexibly disassembling and replacing watch straps or related parts.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the technical scope of the present invention should be included in the scope of protection of the present invention.
