[0033] A watch is a portable time display device worn on the wrist, mainly composed of two parts: the watch body and the watch strap. In order to facilitate people to assemble watches in different styles, the watch strap is usually designed as a detachable structure. However, in the actual research and development and production process, researchers found that traditional watches mainly use spring ears to connect the watch body and the watch strap. The spring ear is a retractable connecting component, mainly composed of a sleeve, a spring inserted in the sleeve, and a spring ear head set at both ends of the spring. When removing and installing the watch strap, the user needs to use a special tool to hold the spring ear head, which requires the user to operate tiny parts, which makes the disassembly and assembly process of the watch strap cumbersome and increases the difficulty of disassembly and assembly of the watch strap.

[0034] The present invention provides a watch, aiming to solve the technical problems of complicated disassembly and assembly process and great difficulty in disassembly and assembly of a watch strap.

[0035] See also Figures 1 to 3 In one embodiment of the present invention, the watch comprises a watch body 100, a locking block 200 and a watch band 300. The watch body 100 is provided with a recessed space 110. The locking block 200 is movably provided in the recessed space 110 and is surrounded with the watch body 100 to form a slot 111. The locking block 200 is provided with a locking portion 210, and the locking block 200 has a fixed position and a release position. The watch band 300 is inserted into the slot 111, and the watch band 300 is provided with a locking groove 310. When the locking block 200 is switched to the fixed position, the locking portion 210 is inserted into the locking groove 310; when the locking block 200 is switched to the release position, the locking portion 210 is disengaged from the locking groove 310.

[0036] The technical solution of the present invention is to movably dispose the locking block 200 in the recessed space 110 and to surround the watch body 100 to form a slot 111 for inserting the watch strap 300, to provide a locking groove 310 on the watch strap 300, to provide a locking portion 210 on the locking block 200, and to movably dispose the locking block 200 in the recessed space 110, so as to fix or loosen the watch strap 300; when the user disassembles the watch strap 300, he only needs to drive the locking block 200 to switch between the fixed position and the loosened position, which can simplify the disassembly and assembly process of the watch strap 300 and reduce the difficulty of disassembly and assembly. In this embodiment, the locking portion 210 may be a protruding structure provided on the locking block 200 and formed integrally with the locking block 200. The locking block 200 is movably provided in the recessed space 110 and is surrounded with the watch body 100 to form a slot 111, and the watch band 300 can be inserted into the slot 111; and the locking block 200 can switch between a fixed position and a loose position to fix or loosen the watch band 300. The locking block 200 can switch to the fixed position so that the locking portion 210 is inserted into the locking slot 310 and fixes the watch band 300, completing the installation and fixing of the watch band 300; at the same time, it can also switch to the loose position so that the locking portion 210 is disengaged from the locking slot 310 and loosens the watch band 300. At this time, the user can pull the watch band 300 and pull the watch band 300 out of the slot 111 to complete the removal of the watch band. That is to say, when the user disassembles the strap 300 of the watch, he only needs to drive the locking block 200 to move and switch the locking block 200 between the fixed position and the loosened position to fix and loosen the strap, thereby completing the installation and removal of the strap; there is no need to use special tools for disassembly and assembly, which can simplify the disassembly and assembly process of the strap 300 and reduce the difficulty of disassembly and assembly.

[0037] In this embodiment, the locking block 200 can be rotatably disposed in the recessed space 110, or can be slidably disposed in the recessed space 110, wherein the sliding direction of the locking block 200 can be the length direction of the strap 300, can be the thickness direction of the strap 300, or can be an oblique direction combining the length direction and the thickness direction. When the locking block 200 is rotatably disposed in the recessed space 110, the user only needs to drive the locking block 200 to rotate so that the locking portion 210 is inserted into the locking groove 310 or is disengaged from the locking groove 310, so as to fix or release the strap 300 and complete the disassembly and assembly of the strap 300; when the locking block 200 is slidably disposed in the recessed space 110, the user only needs to drive the locking block 200 to slide so that the locking portion 210 is inserted into the locking groove 310 or is disengaged from the locking groove 310, so as to fix or release the strap 300 and complete the disassembly and assembly of the strap 300. The above two methods can simplify the disassembly and assembly process of the watch strap 300 and reduce the difficulty of disassembly and assembly of the watch strap 300.

[0038] See also Figure 2In one embodiment of the present invention, the locking block 200 is rotatably disposed in the recessed space 110 via the rotating shaft 220, which can ensure the stability of the locking block 200 when rotating, and an elastic member 230 is disposed between the locking block 200 and the bottom surface of the recessed space 110; Figure 2 As shown in the perspective of , the elastic member 230 can drive the locking block 200 to rotate to a fixed position, so as to drive the locking portion 210 to move toward the bottom surface of the recessed space 110 and insert into the locking groove 310, that is, the elastic member 230 can drive the locking block 200 to rotate counterclockwise. After the strap 300 is inserted into the slot 111, the elastic member 230 can drive the locking portion 210 to rotate to a fixed position, so that the locking portion 210 is automatically inserted into the locking groove 310 and fixes the strap 300, completing the installation of the strap 300, which can simplify the installation process of the strap 300 and reduce the difficulty of installing the strap 300. Specifically, when installing the strap 300, the user only needs to drive the locking block 200 to rotate clockwise, and release the locking block 200 after the strap 300 is inserted into the slot 111, and the locking portion 210 will be driven by the elastic member 230 to press against the end surface of the strap 300 away from the bottom surface of the recessed space 110. As the strap 300 continues to be inserted, the locking portion 210 will slide on the end surface of the strap 300 away from the bottom surface of the recessed space 110 until the locking portion 210 is locked. 10 corresponds to the locking groove 310, the locking portion 210 will be automatically inserted into the locking groove 310 and fix the watchband 300 under the drive of the elastic member 230, and the installation of the watchband 300 is completed; when removing the watchband 300, the user only needs to drive the locking block 200 to rotate clockwise to disengage the locking portion 210 from the locking groove 310 and loosen the watchband 300, and then pull the watchband 300 out of the slot 111 to complete the removal of the watchband 300. In a specific embodiment, the elastic member 230 can be a coil spring.

[0039] See also Figures 1 to 3 In one embodiment of the present invention, the locking portion 210, the rotating shaft 220 and the elastic member 230 are sequentially arranged along the insertion direction of the watch band 300, and the end of the locking block 200 away from the locking portion 210 is spaced apart with a friction protrusion 240, and the friction protrusion 240 is exposed to the watch body 100, wherein the insertion direction of the watch band 300 is as follows: Figure 2As shown by X in the figure. In this embodiment, the locking portion 210, the rotating shaft 220 and the elastic member 230 are sequentially arranged along the insertion direction of the watch band 300. When the watch band 300 is disassembled, the user only needs to press the end of the locking block 200 away from the locking portion 210 to drive the locking block 200 to rotate clockwise, and the user only needs to loosen the end of the locking block 200 away from the locking portion 210, and the locking block 200 can rotate counterclockwise under the push of the elastic member 230. By providing a friction protrusion 240 at the end of the locking block 200 away from the locking portion 210, the friction between the user's finger and the locking member can be increased when the user presses the end of the locking block 200 away from the locking portion 210, thereby reducing the risk of the locking block 200 slipping when the user presses the end of the locking block 200 away from the locking portion 210. In a specific embodiment, when the watch strap 300 is fixed, the end surface of the locking block 200 away from the bottom surface of the recessed space 110 is flush with the outer surface of the watch body 100, and the friction protrusion 240 is arranged on the end surface of the locking block 200 away from the bottom surface of the recessed space 110, and the friction protrusion 240 can be a plurality of strip protrusions spaced apart along the insertion direction of the watch strap 300, or a plurality of evenly arranged point protrusions.

[0040] In one embodiment of the present invention, the watch body 100 is provided with a slide groove 120 communicating with the recessed space 110 and a connecting hole 121 communicating with the slide groove 120, and a locking groove 250 is provided at one end of the locking block 200 away from the locking portion 210, and the locking groove 250 is arranged corresponding to the slide groove 120; the watch also includes a locking assembly 400, the locking assembly 400 includes a slider 410 and a shifting block 420 arranged on the slider 410, the slider 410 is slidably arranged in the slide groove 120, and the shifting block 420 passes through the connecting hole 121 and extends out of the outer surface of the watch body 100; the slider 410 can be inserted into the locking groove 250 to lock the position of the locking block 200. Specifically, when the watch band 300 is fixed, the slider 410 can be inserted into the locking groove 250 to lock the position of the locking block 200. It should be noted that after using the watch, the user usually puts the watch into a storage bag or storage box. However, the storage bag or storage box often contains other items with sharp parts. After the watch is put in, the sharp parts of the other items are very likely to press against the end of the locking block 200 away from the locking portion 210 and squeeze the locking block 200, causing the locking portion 210 to disengage from the locking groove 310, thereby causing the watchband 300 to disengage from the watch body 100. The slider 410 provided in the watch can be inserted into the locking groove 250 when the watchband 300 is fixed, locking the position of the locking block 200, thereby reducing the possibility of the watchband 300 being disengaged from the watch body 100. When the shifting block 420 on the slider 410 passes through the connecting hole 121 and extends out of the outer surface of the watch body 100, it is convenient for the user to drive the slider 410 to move, so that the slider 410 is inserted into or disengaged from the locking groove 250. In a specific embodiment, the slide groove 120 can be set on one side of the recessed space 110 along the length direction of the strap 300, or it can be set on one side of the recessed space 110 along the width direction of the strap 300; that is, the slider 410 can slide to one side of the recessed space 110 along the length direction of the strap 300 to disengage from the locking groove 250, or it can slide to one side of the recessed space 110 along the width direction of the strap 300 to disengage from the locking groove 250.

[0041] In addition to the above-mentioned slider 410 and the shifting block 420, the locking assembly 400 may also include a rotating block and a protruding block disposed on the rotating block. In another embodiment of the present invention, the locking assembly 400 includes a rotating block and a protruding block disposed on the rotating block, the rotating block is rotatably disposed in the slide slot 120 and can be inserted into the locking slot 250, and the protruding block passes through the connecting hole 121 and protrudes from the outer surface of the watch body 100; wherein the rotating block can be inserted into the locking slot 250 to lock the position of the locking block 200 when the watch band 300 is fixed.

[0042] See also Figure 3In one embodiment of the present invention, a limit block 112 is provided in the recessed space 110; when the locking block 200 is switched to the release position, the limit block 112 abuts against the end of the locking block 200 away from the locking portion 210. In this embodiment, the limit block 112 can abut against the end of the locking block 200 away from the locking portion 210 when the locking block 200 is switched to the release position to limit the rotation angle of the locking block 200, thereby making the elastic member 230 move within its elastic limit as much as possible, thereby reducing the strain of the elastic member 230.

[0043] See also Figure 4 In another embodiment of the present invention, the locking portion 210, the elastic member 230 and the rotating shaft 220 are sequentially arranged along the insertion direction of the watchband 300, and a toggle portion 211 is arranged at one end of the locking block 200 close to the locking portion 210. Specifically, when installing the watchband 300, the user only needs to drive the locking block 200 to rotate clockwise through the toggle portion 211, and release the locking block 200 after the watchband 300 is inserted into the slot 111. As the watchband 300 continues to be inserted, the locking portion 210 will automatically insert into the locking slot 310 under the drive of the elastic member 230 and fix the watchband 300, thereby completing the installation of the watchband 300; and when removing the watchband 300, the user only needs to drive the locking block 200 to rotate clockwise through the toggle portion 211, so that the locking portion 210 is disengaged from the locking slot 310 and the watchband 300 is released, and then the watchband 300 is pulled out of the slot 111, thereby completing the removal of the watchband 300. In a specific embodiment, the toggle portion 211 may be a groove provided at one end of the locking block 200 close to the locking portion 210 , or may be a block-shaped protrusion provided at one end of the locking block 200 close to the locking portion 210 .

[0044] It should be noted that when the locking portion 210, the rotating shaft 220 and the elastic member 230 are sequentially arranged along the insertion direction of the watchband 300, the elastic member 230 is always in a compressed state. At this time, the elastic member 230 needs to be restored from the compressed state to the initial state. Therefore, after the user presses the end of the locking block 200 away from the locking portion 210, the elastic member 230 can push the locking block 200 to rotate counterclockwise. When the locking portion 210, the elastic member 230 and the rotating shaft 220 are sequentially arranged along the insertion direction of the watchband 300, the elastic member 230 is always in a stretched state. At this time, the elastic member 230 needs to be restored from the stretched state to the initial state. Therefore, after the user drives the locking block 200 to rotate clockwise through the toggle portion 211, the elastic member 230 can pull the locking block 200 to rotate counterclockwise.

[0045] See also Figure 5In another embodiment of the present invention, the locking block 200 is rotatably disposed in the recessed space 110 via the rotating shaft 220, which can ensure the stability of the locking block 200 during rotation, and the rotating shaft 220 is sleeved with a torsion spring, the first end of the torsion spring is connected to the watch body 100, and the second end of the torsion spring is connected to the locking block 200; Figure 5 As shown in the perspective of , the torsion spring can drive the locking block 200 to rotate to a fixed position, so as to drive the locking portion 210 to move toward the bottom surface of the recessed space 110 and insert into the locking slot 310, that is, the torsion spring can drive the locking block 200 to rotate counterclockwise. After the watchband 300 is inserted into the slot 111, the torsion spring can drive the locking portion 210 to move, so that the locking portion 210 automatically inserts into the locking slot 310 and fixes the watchband 300, completing the installation of the watchband 300, which can simplify the installation process of the watchband 300 and reduce the difficulty of installing the watchband 300. Specifically, when installing the watchband 300, the user only needs to drive the locking block 200 to rotate clockwise, and release the locking block 200 after the watchband 300 is inserted into the slot 111. As the watchband 300 continues to be inserted, the locking portion 210 will automatically insert into the locking slot 310 and fix the position of the watchband 300 under the drive of the torsion spring, completing the installation of the watchband 300.

[0046] See also Figure 3 In one embodiment of the present invention, a first guide surface 320 is disposed at the end of the strap 300 , and a second guide surface 212 is disposed at the locking portion 210 . The second guide surface 212 can abut against the first guide surface 320 . When the watch band 300 is inserted into the slot 111, the first guide surface 320 abuts against the second guide surface 212, and as the watch band 300 is further inserted, the watch band 300 will drive the locking block 200 to rotate clockwise through the cooperation of the first guide surface 320 and the second guide surface 212, so that the locking block 200 climbs to the end surface of the watch band 300 away from the bottom surface of the recessed space 110, and as the watch band 300 is further inserted, the locking portion 210 will slide on the end surface of the watch band 300 away from the bottom surface of the recessed space 110 until the locking portion 210 corresponds to the locking groove 310, and the locking portion 210 will automatically insert into the locking groove 310 under the thrust of the elastic member 230, locking the position of the watch band 300. The provision of the first guide surface 320 and the second guide surface 212 can reduce the difficulty of the user installing the watch band 300. Specifically, when installing the watchband 300, the user only needs to drive the lock block 200 to rotate so that the second guide surface 212 abuts against the first guide surface 320, without making the distance between the locking portion 210 and the bottom surface of the recessed space 110 greater than the thickness of the watchband 300, which can reduce the angle at which the user drives the lock block 200 to rotate, thereby reducing the difficulty of installation. In a specific embodiment, the first guide surface 320 and the second guide surface 212 are both inclined surfaces or curved surfaces; or the first guide surface 320 is one of the inclined surfaces and the curved surface, and the second guide surface 212 is the other of the inclined surfaces and the curved surface.

[0047] See also Figure 3 In one embodiment of the present invention, the locking groove 310 is a hook-shaped groove, the locking portion 210 is a hook-shaped structure, and the locking groove 310 has a side wall 311 close to the end of the strap 300. The strap 300 has an end surface that abuts against the bottom surface of the recessed space 110, and the side wall 311 is inclined from a side away from the end surface to a side close to the end surface along the insertion direction of the strap 300. In this embodiment, by designing the locking groove 310 as a hook-shaped groove and the locking portion 210 as a hook-shaped structure, the strap 300 can be better hooked when the strap 300 is fixed, reducing the risk of the strap 300 and the watch body 100 being separated. In a specific embodiment, the side wall of the end of the locking groove 310 away from the strap 300 is an inclined surface or an arc-shaped surface. Correspondingly, the side of the locking portion 210 away from the rotating shaft 220 should also be an inclined surface or an arc-shaped surface, which can enable the locking portion 210 to be better inserted into the locking groove 310 or detached from the locking groove 310, thereby reducing the risk of the locking portion 210 getting stuck when inserting into the locking groove 310 or detaching from the locking groove 310.

[0048] The specific implementation of the present invention records three different embodiments, and the difference between the three embodiments lies in the rotation axis of the locking block 200 and the structure driving the locking block 200 to rotate. Figure 2 and Figure 3 In the first embodiment, the locking portion 210, the rotating shaft 220 and the elastic member 230 are sequentially arranged along the insertion direction of the strap 300, and the elastic member 230 is arranged between the locking block 200 and the bottom surface of the recessed space 110; see Figure 4 In the second embodiment, the locking portion 210, the elastic member 230 and the rotating shaft 220 are sequentially arranged along the insertion direction of the strap 300, and the elastic member 230 is arranged between the locking block 200 and the bottom surface of the recessed space 110; please refer to Figure 5 In the third embodiment, the locking block 200 is rotatably disposed in the recessed space 110 via the rotating shaft 220, and the rotating shaft 220 is sleeved with a torsion spring. In addition, it should be noted that in the second and third embodiments, a locking structure similar to the locking assembly 400 in the first embodiment can be provided to lock the position of the locking block 200 when the strap 300 is installed on the watch body 100; in the third embodiment, a limiting structure similar to the limiting block 112 in the first embodiment can also be provided to limit the rotation angle of the locking block 200, thereby making the torsion spring move within its elastic limit as much as possible, thereby reducing the strain of the torsion spring.

[0049] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
