[0027] The following will make a detailed description of the implementation manner of the present utility model in conjunction with the accompanying drawings.

[0028] The present utility model provides a watch, which includes a watch dial (not shown in the figure) and a watch band. As shown in Figure 1 —2, the watch band includes a body 200 and a spring bar assembly 100. The spring bar assembly 100 is installed on the body 200 and is used to connect the watch band and the watch dial. The spring bar assembly 100 can be applicable to various types of watch bands such as metal watch bands, leather watch bands, nylon watch bands, rubber watch bands, ceramic watch bands, and braided watch bands. When replacing the watch band or repairing the watch dial, it is necessary to use a special tool to cancel the connection between the spring bar assembly 100 and the watch dial and the watch band, resulting in great difficulty for users to disassemble and assemble the spring bar, and it is not convenient for users to disassemble and assemble the spring bar by themselves.

[0029] In order to reduce the difficulty of disassembling and assembling the spring bar, this embodiment provides a spring bar assembly 100. Specifically, as shown in Figure 3As shown in FIGS. 8, the spring bar assembly 100 includes a mounting base 110, and a button 120, a spring bar 130 and an elastic member 140 disposed in the mounting base 110. The mounting base 110 is provided with a first accommodation cavity 111 and a second accommodation cavity 112 radially distributed along the spring bar 130. The button 120 is disposed in the first accommodation cavity 111, and the spring bar 130 is disposed in the second accommodation cavity 112. A linkage structure is provided between the spring bar 130 and the button 120. The button 120 can move relative to the mounting base 110, and drive the spring bar 130 to slide axially towards the inside of the mounting base 110 through the linkage structure. The elastic member 140 can drive the spring bar 130 to slide axially towards the outside of the mounting base 110. In this embodiment, the first accommodation cavity 111 and the second accommodation cavity 112 that communicate with each other are provided inside the mounting base 110, and the first accommodation cavity 111 and the second accommodation cavity 112 are distributed along the same radial direction of the spring bar 120. At least part of the button 120 is disposed in the first accommodation cavity 111, and at least part of the spring bar 130 is disposed in the second accommodation cavity 112. During installation, at least part of the button 120 can extend into the second accommodation cavity 112, and the button 120 is connected to the spring bar 130 through the linkage structure. The spring bar assembly 100 is installed in the watch band body 200. The button 120 can move relative to the mounting base 110 in the first accommodation cavity 111 under an external force, and drive the spring bar 130 to move relative to the mounting base 110 in the second accommodation cavity 112 through the linkage structure, so that the spring bar 130 extends outwards or retracts inwards towards the mounting base 110, so as to lock and unlock the watch face by the spring bar assembly 100, thereby realizing the connection and disassembly between the watch band body 200 and the watch face. It should be noted that the movement direction of the button 120 is perpendicular to the axial direction of the spring bar 130, and the movement direction of the button 120 is parallel to the distribution direction of the first accommodation cavity 111 and the second accommodation cavity 112. Specifically, as Figure 6 and Figure 7 shown Figure 7The arrow S1 in it is the movement direction of the button 120 under the pressing force, and this arrow S1 is consistent with the distribution direction of the first accommodation cavity 111 and the second accommodation cavity 112 along the radial direction of the spring bar 130. The arrow S2 indicates the direction in which the spring bar 130 retracts towards the inside of the mounting base 110, and the arrow S3 indicates the direction in which the spring bar 130 extends towards the outside of the mounting base 110. When the spring bar assembly 100 locks the watch dial, the button 120 can move towards the second accommodation cavity 112 in the first accommodation cavity 111 under the pressing force, and drive the linkage structure to generate a driving force on the spring bar 130, so that the spring bar 130 retracts axially towards the inside of the mounting base 110. At this time, the spring bar assembly 100 unlocks the watch dial, causing the watch band body 200 to be separated from the watch dial; the elastic member 140 is disposed on the side of the spring bar 130 close to the center of the second accommodation cavity 112. Since the spring bar 130 retracts axially towards the inside of the mounting base 110 in the second accommodation cavity 112, the elastic member 140 is compressed by the spring bar 130 to generate an elastic force, and this elastic force reacts on the spring bar 130 to drive the spring bar 130 to extend towards the outside of the mounting base 110 circumferentially. At this time, the spring bar assembly 100 locks the watch dial, causing the watch band body 200 to be connected to the watch dial. At the same time, during the process of the spring bar 130 extending axially towards the outside of the mounting base 110, the spring bar 130 drives the linkage structure to generate a driving force on the button 120, so that the button 120 moves relative to the mounting base 110 in the first accommodation cavity 111 in a direction away from the second accommodation cavity 112, so as to realize the reset of the button 120.

[0030] During actual operation, the user can directly press the button 120 to move it towards the second accommodation cavity 112 within the first accommodation cavity 111, and drive the spring bar 130 to retract towards the interior of the mounting base 110 within the second accommodation cavity 112 through the linkage structure, so as to unlock the spring assembly 100 from the watch dial, enabling the separation of the watch band body and the watch dial; when the user releases the button 120, the spring bar 130 extends towards the outside of the mounting base 110 within the second accommodation cavity 112 under the elastic force of the elastic member 140, so as to lock the spring assembly 100 with the watch dial, connecting the watch band body and the watch dial. At the same time, during the extension process of the spring bar 130, it drives the linkage structure, and through the linkage structure, drives the button 120 to move towards the outside of the mounting base 110 within the first accommodation cavity 111, causing the button 120 to automatically reset; by arranging the linkage structure between the button 120 and the spring bar 130, one-key disassembly and assembly of the spring assembly 100 are realized, greatly reducing the difficulty of disassembling and assembling the spring, and facilitating the user to disassemble and assemble the spring assembly 100 by themselves to replace the watch band or repair the watch dial. It should be noted that the watch dial is provided with a mating portion for connecting with the spring bar 130. Before the user releases the button 120, align the spring bar 130 with the mating portion on the watch dial. After the user releases the button 120, the spring bar 130 extends towards the outside of the mounting base 110 and inserts into this mating portion to connect the watch band body with the watch dial. Usually, the spring bar 130 and the watch dial are connected by shaft-hole mating.

[0031] Further, as Figure 4As shown in FIGS. 1-8, the linkage structure includes a first guiding portion 121 provided in the button 120 and a second guiding portion 133 provided in the spring bar 130. The button 120 and the spring bar 130 are in contact with each other through the first guiding portion 121 and the second guiding portion 133. The first guiding portion 121 can drive the second guiding portion 133 to drive the spring bar 130 to slide axially into the interior of the mounting base 110. In this embodiment, when the button 120 is pressed and moves in the first accommodating cavity 111 towards the second accommodating cavity 112, and drives the first guiding portion 121 to move synchronously, a lateral acting component force is generated by the first guiding portion 121 on the second guiding portion 133 to drive the spring bar 130 to move and retract into the interior of the mounting base 110 in the second accommodating cavity 112. Similarly, when the pressing force on the button 120 is cancelled, the spring bar 130 is driven by the elastic force of the elastic member 140 to move towards the outside of the mounting base 110 in the second accommodating cavity 112, and drives the second guiding portion 133 to move synchronously. A longitudinal acting component force is generated by the second guiding portion 133 on the first guiding portion 121 to drive the button 120 to move and reset towards the outside of the mounting base 110 in the first accommodating cavity 111. In addition, the first guiding portion 121 is provided in the button 120, and the second guiding portion 133 is provided in the spring bar 130, which simplifies the structure of the spring assembly 100 and is beneficial to improving the assembly efficiency of the spring assembly 100.

[0032] Preferably, as Figure 4 As shown in FIGS. 1-8, the first guiding portion 121 includes a first guiding groove 1211 provided in the button 120 and a first side wall 1212 provided in the first guiding groove 1211. Along the movement direction of the button 120, there is a first preset angle H1 between the extending direction of the first side wall 1212 and the movement direction of the button 120. The button 120 is in contact with the second guiding portion 133 through the first side wall 1212. In this embodiment, at least part of the bottom of the button 120 is recessed upward to form the first guiding groove 1211. The first guiding groove 1211 is provided in the button 120 and the first guiding groove 1211 is open downward, so that at least part of the bottom of the button 120 is open, so that the first side wall 1212 abuts against one side of the second guiding portion 133, which simplifies the structure of the button 120 for the production and manufacture of the button 120. Optionally, the first side wall 1212 is provided in the first guiding groove 1211 and corresponds to the second guiding portion 133. Figure 8The dashed line L in the middle represents the radial and axial direction of the spring bar 130, which is parallel to the moving direction of the button 120 under the pressing force. The first side wall 1212 extends towards the bottom of the button 120 along the moving direction of the button 120, and there is a first preset angle H1 between the extending direction of the first side wall 1212 and the moving direction of the button 120. Optionally, as Figure 8 shown, the first side wall 1212 can be set as an inclined plane, and the first side wall 1212 is opposite to the bottom of the first guiding groove 1211. There is the first preset angle H1 between the first side wall 1212 and the dashed line L. By setting the first side wall 1212 as an inclined plane, the structure of the first guiding portion 121 is simplified, which is beneficial to the production and installation of the button 120 and helps to reduce the production cost of the spring assembly 100.

[0033] In addition, as Figure 4 shown in FIG. -8, the first guiding groove 1211 extends towards the top of the button 120 and forms a relief groove above the first side wall 1212. When the button 120 is subjected to an external force and moves towards the second accommodation cavity 112 in the first accommodation cavity 111, that is, when the button 120 moves towards the spring bar 130, the relief groove provides clearance for the spring bar 130 to ensure the normal telescopic movement of the spring bar 130. Further, the top of the first guiding groove 1211 (i.e., the top of the relief groove) is set as the fourth side wall 1213. When the button 120 is subjected to an external force and moves towards the second accommodation cavity 112 in the first accommodation cavity 111 and drives the first side wall 1212 to move synchronously, the button 120 can move until it contacts the top of the spring bar 130 with the fourth side wall 1213. The movement distance of the button 120 is restricted by the fourth side wall 1213, thereby restricting the telescopic distance of the spring bar 130 to improve the movement stability of the button 120 and the unlocking and locking efficiency of the spring assembly 100 for the watch dial.

[0034] Preferably, as Figure 4 shown in FIG. -8, Figure 8The dashed line L therein represents the radial axis of the spring bar 130. The second guiding portion 133 includes a second guiding groove 1331 provided in the spring bar 130 and a second side wall 1332 provided in the second guiding groove 1331. Along the radial direction of the spring bar 130, there is a second preset angle H2 between the extending direction of the second side wall 1332 and the radial direction of the spring bar 130. The spring bar 130 abuts against the first guiding portion 121 through the second side wall 1332. In this embodiment, the second guiding portion 133 is provided in the spring bar 130. At least part of the top of the spring bar 130 is recessed downward to form the second guiding groove 1331. The second guiding groove 1331 is open upward, so that at least part of the top of the spring bar 130 is open. The second guiding groove 1331 is provided with a second side wall 1332. During installation, at least part of the first side wall 1212 of the button 120 can extend into the second guiding groove 1331 and abut against the second side wall 1332. Optionally, the second side wall 1332 extends along the radial direction of the spring bar 130 towards the bottom of the spring bar 130, and there is a second preset angle H2 between the extending direction of the second side wall 1332 and the radial direction of the spring bar 130. Optionally, as Figure 8 shown, the second side wall 1332 can be set as an inclined plane, and the second side wall 1332 is opposite to the top of the second guiding groove 1331. There is the second preset angle H2 between the second side wall 1332 and the dashed line L. By setting the second side wall 1332 as an inclined plane, the structure of the second guiding portion 133 is simplified, which is beneficial to the production and installation of the spring bar 130 and helps to reduce the production cost of the spring assembly 100. It should be noted that the radial direction of the spring bar 130 is parallel to the distribution directions of the first accommodating cavity 111 and the second accommodating cavity 112.

[0035] In addition, as Figure 4 shown in FIG. 8, the second guiding portion 133 further includes a third side wall 1333 provided in the second guiding groove 1331. The third side wall 1333 is connected to the second side wall 1332. There is a third preset angle between the extending direction of the third side wall 1333 and the extending direction of the second side wall 1332, or between the extending direction of the third side wall 1333 and the radial direction of the spring bar 130. As Figure 8 shown, Figure 8The dashed line L therein represents the radial axis of the spring bar 130. The third side wall 1333 is connected to the second side wall 1332, and the third side wall 1333 extends along the axial direction of the spring bar 130 towards the end of the spring bar 130. Optionally, there is a third preset angle H3a between the extending direction of the third side wall 1333 and the extending direction of the second side wall 1332, that is, the third preset angle H3a is formed between the third side wall 1333 and the second side wall 1332; or, optionally, the third preset angle H3b is formed between the extending direction of the third side wall 1333 and the radial direction of the spring bar 130, that is, the third preset angle H3b is formed between the third side wall 1333 and the dashed line L; in this embodiment, the third side wall 1333 can be understood as the bottom of the second guiding groove 1331. Preferably, the third side wall 1333 extends along the axial direction of the spring bar 130, and the third preset angle H3b is preferably 90°; when the button 120 moves relative to the second side wall 1332 through the first side wall 1212 under an external force, the button 120 can move to contact the third side wall 1333, and the movement distance of the button 120 is restricted by the third side wall 1333, so as to restrict the telescopic distance of the spring bar 130, thereby improving the movement stability of the button 120 and the unlocking and locking efficiency of the spring bar assembly 100 for the watch dial.

[0036] Specifically, as Figure 6 and Figure 7 shown, the unlocking and locking processes of the spring bar assembly 100 are as follows:

[0037] The user can directly press the button 120 to move it in the first accommodation cavity 111 towards the second accommodation cavity 112, and drive the first side wall 1212 to move downward relative to the second side wall 1332. A lateral acting component force is generated on the second side wall 1332 through the first side wall 1212 to drive the spring bar 130 to retract towards the inside of the mounting seat 110 in the second accommodation cavity 112, so that the spring bar assembly 100 is unlocked from the watch dial, and the watch band body and the watch dial can be separated; when the user releases the button 120, the spring bar 130 extends towards the outside of the mounting seat 110 in the second accommodation cavity 112 under the elastic force of the elastic member 140, so that the spring bar assembly 100 is locked with the watch dial, and the watch band body and the watch dial are connected. At the same time, the spring bar 130 drives the second side wall 1332 to move synchronously during the extending process, so that the second side wall 1332 generates a longitudinal acting component force on the first side wall 1212 to drive the button 120 to move towards the outside of the mounting seat 110 in the first accommodation cavity 111, so that the button 120 automatically resets.

[0038] In other embodiments, as Figure 4As shown in FIGS. 8, the mounting base 110 includes a sleeve 113 and a sleeve rod 114. The first accommodating cavity 111 is provided inside the sleeve 113, and the second accommodating cavity 112 is provided inside the sleeve rod 114. The first accommodating cavity 111 communicates with the second accommodating cavity 112. The first accommodating cavity 111 communicates with the outside to allow the button 120 to pass through the outside of the sleeve 113. The second accommodating cavity 112 communicates with the outside to allow the spring bar 130 to pass through the outside of the sleeve rod 114. In this embodiment, the sleeve 113 is provided at the upper part of the sleeve rod 114, so that the first accommodating cavity 111 and the second accommodating cavity 112 can be distributed along the same radial direction of the spring bar 130. The top of the sleeve 113 is provided with a first through hole adapted to the button 120, and the first accommodating cavity 111 communicates with the outside through the first through hole, so that at least part of the button 120 can extend out of the sleeve 113 through the first through hole for the user to press. The end of the sleeve rod 114 is provided with a second through hole adapted to the spring bar 130, and the second accommodating cavity 112 communicates with the outside through the second through hole, so that at least part of the spring bar 130 can extend out of the sleeve rod 114 through the second through hole and be connected to the mating part in the watch dial. In addition, a clamping part 123 is provided in the button 120. The clamping part 123 extends outward from the end of the button 120. The clamping part 123 can move in the second accommodating cavity 112 through the button 120 and abut against the top of the second accommodating cavity 112 or the spring bar 130. During installation, the clamping part 123 can extend into the second accommodating cavity 112 through the button 120, and the first side wall 1212 contacts the second side wall 1332 to connect the button 120 to the spring bar 130. When the button 120 is pressed and moves in the first accommodating cavity 111 towards the second accommodating cavity 112, the clamping part 123 is driven to move synchronously through the button 120, and the button 120 moves until the clamping part 123 contacts the top of the second accommodating cavity 112 (i.e., the inner wall of the sleeve rod 114) or the spring bar 130 (i.e., the third side wall 1333). By providing the clamping part 123 in the button 120, the moving distance of the button 120 can be limited, thereby limiting the telescopic distance of the spring bar 130, improving the connection stability of the button 120, and the unlocking and locking efficiency of the spring bar assembly 100 for the watch dial. Moreover, when the button 120 is reset, the button 120 moves until the clamping part 123 contacts the inner wall of the sleeve rod 114 to prevent the button 120 from popping out of the mounting base 110 and detaching from the mounting base 110 when reset, thereby ensuring the structural integrity of the spring bar assembly 100.

[0039] Optionally, in one of the embodiments of the mounting base 110, the mounting base 110 is integrally formed, that is, the sleeve 113 and the sleeve rod 114 are integrally designed, which is beneficial to simplifying the production process of the mounting base 110 and improving the production efficiency of the mounting base 110. Optionally, in the second embodiment of the mounting base 110, the sleeve 113 and the sleeve rod 114 are separately provided. The sleeve 113 is connected to the upper part of the sleeve rod 114.
