[0032] In order to make the technical purpose, technical scheme and technical effect of the present invention clearer and to facilitate those skilled in the art to understand and implement the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] like Figure 1-Figure 3 As shown, Figure 1 A schematic diagram showing the structure of a hidden bar according to a preferred embodiment of the present invention; Figure 2 Shows Figure 1 A schematic diagram of the structure of the first spring piece, the second spring piece and the tube of the hidden bar shown; Figure 3 Shows Figure 1 The structure diagram of the bar tube of the hidden bar structure is shown. Specifically, the hidden bar structure is installed on the watch case 1, and a receiving slot 3 is provided on the watch case 1, and a connecting hole 17 communicating with the inside of the watch case 1 is provided at the bottom of the slot of the receiving slot 3; the hidden bar structure includes a main shaft 8 passing through the connecting hole 17, a bar tube 9 passing through the connecting hole 17 and slidably sleeved on the main shaft 8, and a main body 6 of the bar which is axially fixedly connected to the bar tube 9 and connected to the bottom of the receiving slot 3 through a first spring 61, and axially connected to the main shaft 8 through a second spring 62;

[0034] A first annular groove 91 is formed on the outer circumference of the tube 9; a first truncated cone portion 95 is formed on one side of the tube 9 adjacent to the first groove 91, and a first cylindrical portion 92 is formed on the other side of the tube 9 adjacent to the first groove 91;

[0035] The structure of the hidden bar further includes a first elastic piece 12 and a second elastic piece 2 respectively installed in the watch case 1; the first elastic piece 12 and the second elastic piece 2 are respectively located on both sides of the bar tube 9 and cooperate to surround the bar tube 9;

[0036] The first spring piece 12 is used to be stuck in the first slot 91 when the main body 6 of the bar is completely accommodated in the accommodating slot 3; the first spring piece 12 is also used to slide along the side wall of the first conical portion 95 and be pushed by the second spring piece 2 when the main body 6 of the bar that is completely accommodated in the accommodating slot 3 continues to be pressed down, so that the first spring piece 12 and the second spring piece 2 can achieve a force balance when neither of them is in contact with the tube 9 of the bar, thereby facilitating the main body 6 of the bar to pop out of the accommodating slot 3 under the action of the first spring 61 and the second spring 62.

[0037] The above technical solution is a basic solution, and it should be understood that in order to form the first slot 91, the bottom diameters of the first truncated cone portion 95 and the first cylindrical portion 92 are both larger than the bottom diameter of the first slot 91. At the same time, it can be understood that when the first elastic sheet 12 is stuck in the first slot 91, the first elastic sheet 12 has pressed the second elastic sheet 2 to deform it; at the same time, through the cooperation of the first elastic sheet 12 and the first slot 91, the main body 6 of the bar can remain in a hidden state.

[0038] Furthermore, the structure of the hidden bar also includes a first cylindrical pin 15 and a second cylindrical pin 16 respectively installed in the case 1 and arranged parallel to the main axis 8, the second spring piece 2 is rotatably installed on the second cylindrical pin 16, the first spring piece 12 is rotatably installed on the first cylindrical pin 15, and crosses the bar tube 9, and detachably abuts the second spring piece 2.

[0039] Furthermore, the outer side wall of the main body 6 of the bar is provided with an annular second slot 63, and the structure of the hidden bar further includes a first sealing ring 11 clamped in the second slot 63. The first sealing ring 11 is used to achieve sealing between the outer side wall of the main body 6 of the bar and the inner side wall of the receiving tank body 3.

[0040] Furthermore, a barrel portion 31 axially connected to the communication hole 17 is formed at the bottom of the receiving tank body 3; an annular third clamping groove 96 is also formed on the outer side wall of the tube 9 of the bar, and the structure of the hidden bar further includes a second sealing ring 4 clamped in the third clamping groove 96. The second sealing ring 4 can achieve sealing between the inner side wall of the barrel portion 31 and the outer side wall of the tube 9 of the bar.

[0041] Furthermore, an outer side wall of the main body 6 of the bar is provided with an annular groove-shaped nail position 5, through which the main body 6 of the bar can be easily pulled out.

[0042] Furthermore, the structure of the hidden bar further includes a bushing 10, which is axially fixedly mounted on the main body 6 of the bar; the bushing 10 is slidably sleeved on the barrel 31; the first spring 61 is sleeved on the bushing 10 and connected to the main body 6 of the bar through the substrate of the bushing 10; a fourth clamping groove 32 is provided on the outer wall of the barrel 31, and the structure of the hidden bar further includes a third sealing ring 7 clamped in the fourth clamping groove 32. The third sealing ring 7 can achieve sealing between the outer wall of the barrel 31 and the inner wall of the bushing 10.

[0043] Furthermore, the structure of the hidden bar also includes a pressure block 14 installed in the watch case 1, and a bolt 13 fixing the pressure block 14 on the watch case 1; a first cylindrical pin 15 and a second cylindrical pin 16 are respectively installed on the pressure block 14.

[0044] Furthermore, the tube 9 of Bar forms a second conical portion 93 at a portion adjacent to the first cylindrical portion 92 and facing away from the first slot 91 ; the tube 9 of Bar forms a third cylindrical portion 94 at a portion adjacent to the second conical portion 93 and facing away from the first cylindrical portion 92 .

[0045] In this embodiment, the use process of the hidden bar structure is as follows: when the main body 6 of the bar is just completely accommodated in the accommodating groove 3, the first spring piece 12 is clamped on the first clamping groove 91, and under the restriction of the first spring piece 12 and the first truncated cone portion 95, the second spring piece 2 will be deformed, such as Figure 4-Figure 5shown.

[0046] When the main body 6 of the bar is pressed downward, the main body 6 of the bar together with the bar tube 9 and the bushing 10 move into the case 1, and the first spring piece 12 is affected by the bar tube 9, slides along the first truncated cone portion 95 on the bar tube 9, deforms, and is stuck on the first truncated cone portion 95; the second spring piece 2 is reset and stuck on the first cylindrical portion 92, as shown in FIG. Figure 6-Figure 7 shown.

[0047] When the main body 6 of the bar is released, the first spring 61 and the second spring 62 rebound, driving the main body 6 of the bar and the tube 9 of the bar to bounce outward, and the first spring sheet 12 and the second spring sheet 2 soon no longer contact the tube 9 of the bar, and a force balance is achieved, so that the tube 9 of the bar continues to move outward. Figure 8 During the reset process of the first spring 61 and the second spring 62, the nail position 5 is exposed, the second spring piece 2 slides along the second truncated cone portion 93, separates from the first spring piece 12, and finally gets stuck on the third cylindrical portion 94; the first spring piece 12 gets stuck on the first cylindrical portion 92, as shown. Figure 9-10 At this time, by rotating the main body 6 of the watch, the date and day of the week can be adjusted.

[0048] Hold the nail position 5 and pull the main body 6 of the bar outward, the first spring piece 12 passes through the second truncated cone portion 93 and is stuck on the third cylindrical portion 94 together with the second spring piece 2, as shown in FIG. Figure 11-Figure 12 As shown. At this time, the main body 6 of the bar can be rotated to adjust the watch time. After the adjustment is completed, the main body 6 of the bar is pressed, and the main body 6 of the bar drives the tube 9 of the bar to move, so that the first elastic sheet 12 can be re-engaged in the first engagement groove 91; at this time, the main body 6 of the bar is re-accommodated in the accommodation groove 3.

[0049] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the appended claims of the present invention.
