DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1 , Figure 2 As shown, a stopping mechanism for a clock striking mechanism comprises a rotating shaft 1, a pendulum 2 is fixedly connected to the surface of the rotating shaft 1, a hammer 3 is fixedly connected to the right end of the pendulum 2, a meshing tooth 4 is fixedly connected to the left end of the pendulum 2, a rebound component 6 is fixedly connected to the bottom of the rotating shaft 1, and a stopping component 5 is meshed with the surface of the meshing tooth 4.

[0027] The swing rod 2 drives the hammer 3 with the rotating shaft 1 as the axis to strike the object to make a sound, thereby achieving the effect of telling time.

[0028] like Figure 3 , Figure 4 As shown, the stop assembly 5 includes a semicircular gear 51 and an hour hand gear 55. The outer surface of the semicircular gear 51 meshes with the outer surface of the meshing tooth 4. The top surface of the hour hand gear 55 is fixedly connected to the shaft rod 58, and the outer surface of the shaft rod 58 is fixedly connected to the hour hand 59.

[0029] Furthermore, the hour hand gear 55 rotates once every hour, the top surface of the hour hand gear 55 is rotatably connected to the minute hand gear 56 and the minute hand gear 56 rotates once every minute, the top surface of the minute hand gear 56 is fixedly connected to the minute hand 57 and the inner side of the minute hand 57 is rotatably connected to the outer surface of the shaft 2 58.

[0030] An hour hand gear 55 is provided, which is driven by a driving wheel of the clock and rotates once every hour, so that the hammer 3 can swing and strike once every hour.

[0031] like Figure 3 , Figure 4 As shown, the bottom surface of the hour hand gear 55 is fixedly connected to the shaft rod 1 54, the outer surface of the shaft rod 1 54 is fixedly connected to the transmission gear 53, the outer surface of the transmission gear 53 is meshed with the driven gear 52, and the bottom surface of the driven gear 52 is fixedly connected to the top surface of the semicircular gear 51.

[0032] A shaft 54, a transmission gear 53 and a driven gear 52 are provided. Under the action of the shaft 54, when the hour gear 55 rotates every hour, the transmission gear 53 and the driven gear 52 also rotate accordingly, maintaining the same twelve-hour rotation frequency as the hour gear 55.

[0033] like Figure 3 , Figure 4 As shown, the semicircular gear 51 is a 24-hour system, and the incomplete position of the semicircular gear 51 corresponds to 22:00 to 6:00 on the clock.

[0034] A semicircular gear 51 is provided. Since the semicircular gear 51 is in a 24-hour format, when the hour hand gear 55 rotates to night, the semicircular gear 51 rotates again. However, due to the defect on the surface, the rocker 2 cannot be driven to rotate through the meshing teeth 4, thereby stopping the timekeeping.

[0035] like Figure 5 , Figure 6 As shown, the rebound assembly 6 includes a fixed disk 61 and a transmission shaft 62, the top surface of the transmission shaft 62 is fixedly connected to the bottom surface of the rotating shaft 1, the bottom surface of the transmission shaft 62 is rotatably connected to the top surface of the fixed disk 61, the top of the fixed disk 61 is fixedly connected to a fixing column 64, and the top surface of the fixed disk 61 is fixedly connected to a baffle 63.

[0036] Furthermore, a hairspring 65 is fixedly connected to the outer surface of the transmission shaft 62 , and the hairspring 65 spirally expands outward from the axis of the transmission shaft 62 , and the other end of the hairspring 65 is fixedly connected to the outer surface of the fixing column 64 .

[0037] A hairspring 65, a fixed column 64 and a transmission shaft 62 are provided. When the transmission shaft 62 is rotated on the fixed plate 61, the hairspring 65 is driven to rotate, and the end is restricted by the fixed column 64, so that it is rolled and contracted around the transmission shaft 62 as the axis. When no longer subjected to force, the hairspring 65 rebounds outwards to drive the transmission shaft 62 to rotate repeatedly until it is completely released.

[0038] like Figure 5 , Figure 6 As shown, the bottom surface of the fixed plate 61 is rotatably connected to an adjusting wheel 68 , the outer surface of the adjusting wheel 68 is fixedly connected to a bracket 67 , the end of the bracket 67 is fixedly connected to an adjusting block 66 , and the inside of the adjusting block 66 is movably connected to the surface of the hairspring 65 .

[0039] An adjusting wheel 68 and an adjusting block 66 are provided, and the adjusting wheel 68 is rotated to allow the adjusting block 66 to move on the surface of the hairspring 65. When the distance between the adjusting block 66 and the fixed column 64 is larger, the energy that the hairspring 65 can absorb is smaller, and the coil volume becomes smaller accordingly, so that the pressure is also smaller when it is released, thereby reducing the number of swings of the hammer 3.

[0040] The working principle of the utility model is as follows: the hour hand gear 55 is driven to rotate by the driving wheel of the clock, and the frequency of rotation is once every hour. Under the action of the shaft 1 54, the transmission gear 53 and the driven gear 52 also rotate with the hour hand gear 55 when it rotates every hour, and keep the same twelve-hour rotation frequency as the hour hand gear 55, thereby driving the semicircular gear 51 of the twenty-four-hour system to rotate, and the swing rod 2 drives the hammer 3 to strike the object with the shaft 1 as the axis through the meshing teeth 4 to make a sound so as to achieve the effect of telling time, and when the shaft 1 rotates, it drives the transmission shaft 62 on the fixed plate 61 to rotate, and drives the hairspring 65 to rotate, and the end is limited by the fixed column 64, so that it rolls with the transmission shaft 62 as the axis. Contraction, when no longer under force, the hairspring 65 rebounds outwards to drive the transmission shaft 62 to rotate repeatedly until it is completely released, so that the hammer 3 can swing and strike once every hour. The adjusting wheel 68 can also be turned to allow the adjusting block 66 to move on the surface of the hairspring 65. When the distance between the adjusting block 66 and the fixed column 64 is larger, the energy that the hairspring 65 can absorb is smaller, and the coil volume becomes smaller, so that it is smaller when the pressure is released again, thereby reducing the number of swings of the hammer 3. When night comes, since the semicircular gear 51 is a 24-hour system, when the hour hand gear 55 rotates to night, the semicircular gear 51 rotates again, and its surface cannot drive the pendulum 2 to rotate through the meshing teeth 4 due to the defect, so as to stop the timekeeping.

[0041] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
