Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical clocks, and in particular relates to a mechanical clock time-telling device. Background Art

[0002] The power for the mechanical clock's timekeeping is provided by the descent of the timekeeping power hammer under the action of gravity. When it is not necessary to tell the time, the timekeeping power hammer will remain stationary under the action of a mechanical limit device; when it is necessary to perform the timekeeping operation, the limiting effect of the above-mentioned limit mechanism will be cancelled, and the timekeeping power hammer will then descend under the action of its own gravity. During the descent, the gear system will be driven by a chain or rope to drive the clock hammer to strike the bronze bell, making a timekeeping sound; and when the timekeeping is finished, for example, at 2 o'clock, after the clock hammer strikes the bronze bell twice, the timekeeping power hammer will stop descending under the action of the limit mechanism, and the timekeeping will stop; if the next round of timekeeping is to be performed at 2:30, the limit mechanism will cancel the limit mechanism again. The time-telling power weight continues to descend, and this pattern is repeated. Obviously, the size of the clock itself is limited, and the space for the time-telling power weight to descend must be limited. If the time-telling power weight descends to the lower limit position, such as touching the bottom plate of the base of the clock, it can no longer continue to descend, and it can no longer provide power for the clock hammer. Therefore, when it is detected that the time-telling power weight has descended to a certain position close to the ground or the bottom of the clock case, it is necessary to start the lifting motor and other power mechanisms to lift the time-telling power weight back to the upper limit position, and continue to rely on the descent of the time-telling power weight to provide kinetic energy when the time is needed next time.

[0003] However, since the heavy hammer cannot provide kinetic energy to the clock hammer during the process of re-lifting, simply setting a position detection switch at the bottom of the clock and immediately lifting the heavy hammer once it is triggered will cause the time telling to stop before it ends. For example, at 2 o'clock, it should be struck twice, but when the clock hammer strikes once and has not struck the second time, the time telling power hammer touches the trigger mechanism, and the system immediately drives the lifting device to lift the time telling power hammer. The clock hammer loses kinetic energy, and the time telling stops, which will result in missed time. Utility Model Content

[0004] In view of the above deficiencies in the prior art, the purpose of the present invention is to provide a mechanical clock time-telling device.

[0005] In order to achieve the above objectives, the technical solutions adopted are:

[0006] A mechanical clock time-sounding device includes a time-sounding power hammer, a transmission mechanism and a hammer. The time-sounding power hammer is connected to the hammer through the transmission mechanism. When the time is needed, the time-sounding power hammer descends under the action of gravity, thereby driving the hammer to strike and tell the time. A position detection switch is provided on the descending path of the time-sounding power hammer. The position detection switch is connected to the lifting mechanism through a control unit. The position detection switch is a delay switch, which is used to send a trigger signal to the control unit after a delay setting threshold after the time-sounding power hammer descends and triggers the position detection switch, so that after the time-sounding power hammer descends to the position detection switch, the delay setting threshold is raised again.

[0007] On the basis of the above technical solution, the present invention can also make the following improvements:

[0008] Furthermore, the extreme position of the descent of the time-telling power hammer is called the lower extreme position, and the distance between the position detection switch and the lower extreme position is greater than the distance the time-telling power hammer descends within the time T1 when the hammer strikes 12 times.

[0009] The beneficial effect of adopting the above-mentioned further technical scheme is that even in the most extreme circumstances, such as at 12 o'clock, the clock hammer needs to strike 12 times, and the position detection switch is triggered as soon as the time-telling power hammer is started (even before the first strike). Since this position detection switch is a delay switch, it will not send a signal to the outside immediately, and the time for delaying the sending of the signal is enough for the clock hammer to complete 12 strikes. Moreover, the vertical distance between the current position of the time-telling power hammer and its lower limit position is greater than the distance the time-telling power hammer falls within the time T1 when the clock hammer strikes 12 times, that is, the time-telling power hammer also has enough space to fall for the clock hammer to complete its 12 strikes. Therefore, this scheme will no longer stop the time-telling due to the sudden lifting of the time-telling power hammer, thus avoiding missed reports in this case.

[0010] Furthermore, the position detection switch is one of a contact mechanism, a reed switch, a proximity switch, and a beam switch.

[0011] Furthermore, a bracket is provided below the position detection switch, a base or ground is provided below the time signal power hammer, and the lower end of the bracket is installed on the base or ground.

[0012] The beneficial effects of adopting the above-mentioned further technical solution are: providing a bracket below the position detection switch can place the position detection switch at a sufficient height, leaving space for the descent of the timekeeping power hammer, and can enhance the stability of the position detection switch.

[0013] Furthermore, the delay setting threshold of the position detection switch is T, and T satisfies T1<T<(T3-T2), wherein T1 is the time required for the clock hammer to strike 12 times, T2 is the time required for the timekeeping power hammer to rise from the lower limit position to the height limit position, and T3 is the shortest time interval between two adjacent timekeeping.

[0014] Furthermore, T3 is 30 min or 60 min.

[0015] The beneficial effects of the above two-step technical solution are as follows: T3 is 30 minutes or 60 minutes because ordinary mechanical clocks usually strike the time at intervals of one hour or half an hour, and T1 and T3-T2 represent two extreme cases of delay:

[0016] The first state is to lift up immediately after the time is finished. In this case, the longest single time is limited, that is, starting from the time-telling power hammer triggering the position detection switch, the hammer may continue to strike 12 times at most (for example, 12 o'clock). At this time, the hammer drops the corresponding distance, and the shortest delay time is the time for 12 time sounds. After completing 12 knocks, the delay time ends, and the lifting of the time-telling power hammer is immediately started, corresponding to the delay time T1. If it is 1 o'clock, only 1 knock is needed, and it will wait for 12 knocks before lifting up.

[0017] Another extreme situation is that after the time signal ends, the time signal power hammer is not raised immediately. Instead, it is raised when the next time signal is about to start. For example, the next time signal may be half an hour or an hour (this depends on whether the clock is designed with a half-hour time signal function). Assuming that the half-hour time signal function is provided, the most extreme situation is still that the position detection switch is triggered as soon as the time signal starts. In this case, the time from the moment the position detection switch is triggered to the next time signal is 30 minutes. In addition, time must be left for raising the hammer, so the longest delay time is T3-T2, otherwise it will affect the next time signal. In daily actual use, this extreme situation should be avoided as much as possible and the setting should be centered to ensure stable operation.

[0018] Furthermore, the vertical distance between the position detection switch and the base or the ground is not less than 300 mm.

[0019] Furthermore, the lifting mechanism includes a gear system and a lifting motor, and the lifting motor can drive the gear system to drive the time-telling power hammer to lift.

[0020] Furthermore, the transmission mechanism includes a gear system.

[0021] Furthermore, the time signaling power hammer is connected to the gear system above through a chain or a rope.

[0022] Compared with the prior art, the beneficial effect of the present invention is that the mechanical clock time-telling device provided by the present invention adopts a switch with an added delay setting to realize the automatic lifting of the time-telling power hammer, which can eliminate the time-telling omission in critical situations and improve the reliability of the time-telling.

[0029] Reference Figures 1 and 2A mechanical clock time-telling device includes a time-telling power hammer 100, a transmission mechanism and a hammer. The time-telling power hammer 100 is connected to the hammer through the transmission mechanism. When time is needed, the time-telling power hammer 100 drops under the action of gravity, thereby driving the hammer to strike and tell time. A position detection switch 201 is provided on the descending path of the time-telling power hammer 100. The position detection switch 201 is connected to the lifting mechanism through a control unit. The position detection switch 201 is a delay switch, which is used to send a trigger signal to the control unit after a delay setting threshold after the time-telling power hammer 100 drops and triggers the position detection switch 201, so that after the time-telling power hammer 100 drops to the position detection switch 201, the delay setting threshold is raised again.

[0030] In an optional embodiment, the extreme position of the descent of the time-telling power hammer 100 is called the lower extreme position, and the distance between the position detection switch 201 and the lower extreme position is greater than the distance the time-telling power hammer 100 descends within the time T1 when the hammer strikes 12 times.

[0031] In an optional embodiment, the position detection switch 201 is one of a contact mechanism, a reed switch, a proximity switch, and a beam switch.

[0032] In this embodiment, specifically, a bracket 202 is provided below the position detection switch 201 , a base or ground 300 is provided below the time signal power hammer 100 , and the lower end of the bracket 202 is installed on the base or ground 300 .

[0033] In an optional embodiment, the delay setting threshold of the position detection switch 201 is T, and T satisfies T1<T<(T3-T2), wherein T1 is the time required for the clock hammer to strike 12 times, T2 is the time required for the timekeeping power hammer 100 to rise from the lower limit position to the height limit position, and T3 is the shortest time interval between two adjacent timekeeping.

[0034] In this embodiment, specifically, T3 is 30 min or 60 min.

[0035] In this embodiment, specifically, the vertical distance between the position detection switch 201 and the base or the ground 300 is not less than 300 mm.

[0036] In an optional embodiment, the lifting mechanism includes a gear system 401 and a lifting motor 402. The lifting motor 402 can drive the gear system 401 to drive the time-telling power hammer 100 to lift.

[0037] In this embodiment, specifically, the transmission mechanism includes a gear system 401 .

[0038] In an optional embodiment, the time signal power hammer 100 is connected to the upper gear system 401 through a chain or rope 501.

[0039] During operation, when it is not necessary to tell the time, the time-telling power hammer 100 is prevented from falling under the action of gravity, and the time-telling power hammer 100 will remain stationary under the action of a limiting mechanism such as a mechanical limiting device or an electrical control; when it is necessary to perform the time-telling operation, the limiting effect of the above-mentioned limiting mechanism needs to be cancelled, and at this time, the time-telling power hammer 100 will fall under the action of its own gravity. During the falling process, the gear system 401 is driven by a chain or rope 501 to drive the clock hammer to strike the bronze bell, making a time-telling sound; and when it is necessary to end the time-telling, for example, at 2 o'clock, after the clock hammer strikes the bronze bell twice, the time-telling power hammer 100 will remain stationary under the action of the limiting mechanism, and the time-telling will stop; if the next round of time-telling is to be performed at 2:30, the limiting mechanism will cancel the limit again, and the time-telling power hammer 100 will continue to fall, and this rule will be repeated. When the time-telling power hammer 100 When it descends to a certain extent, it will touch the position detection switch 201, causing the position detection switch 201 to change from the initial off state to the on state, and send this on signal to the control unit. After receiving the signal, the control unit will delay, and the delay setting threshold T satisfies T1<T<(T3-T2). For example, T3 is 30 minutes at this time, T1 is the time required for the clock hammer to strike 12 times, and T2 is the time required for the time-telling power hammer 100 to rise from the lower limit position to the height limit position. During the delay time T, the time-telling power hammer 100 will continue to descend until this round of time-telling ends, and after the delay time reaches T, the control unit sends an instruction to the lifting motor 402, and the lifting motor 402 drives the gear system 401 to operate. The gear system 401 lifts the time-telling power hammer 100 through the chain or rope 501, waiting for the next round of time-telling.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
