A timekeeper is an instrument or person that measures the passage of time.

Timekeeper with a Mechanism for Measuring Settable Predetermined Periods

This timekeeper comprises a first timer (4), means (12) for connecting it selectively to the train of the timekeeper (T), a second timer (5), a synchronous coupling between the first (4) and second (5) timers, and fly-back means (13, 13′, 9, 11) for said timers (4, 5). An auxiliary motive source (10′) is in a driving relationship with the second timer (5) and a one-way coupling (6a, 7a) is situated between the first (4) and second (5) timers to regulate the speed of movement of the latter at a predetermined ratio with the speed of movement of the first timer (4) while allowing one-way relative movement of the first timer (4) relative to the second (5) when the latter is in the stop position and one-way relative movement in the opposite sense of the second timer (5) when the first timer (4) is in the stop position.

Timekeeper and time feedback, time calibration and pointer positioning method

The invention relates to a timekeeper and a time feedback, time calibration and pointer positioning method. The timekeeper at least comprises a hour wheel sheet, a minute wheel sheet, an electric motor and a controller, wherein the minute wheel sheet is provided with a light hole, and the upside and the downside of the light hole of the minute wheel sheet are respectively provided with an infrared optical coupling generating side and an infrared optical coupling receiving side; the infrared optical coupling receiving side generates a position feedback signal and sends to the controller when receiving infrared light; and when receiving the position feedback signal, the controller obtains the current-time minute number of the timekeeper, and determines the current indication time of the timekeeper by cooperating with an hour counter, wherein the current-time minute number of the timekeeper is a minute number preset by a software. An infrared optical coupling apparatus disclosed by the invention is capable of generating the position feedback signal and sending to the controller when the light hole passes the exact downside of the apparatus, so that the current time of the timekeeper is determined, the effective time feedback and reliable transmission of pointer position are realized, and further calibration of the timekeeper is realized, and through assistant intelligent positioning of a pointer by a software, convenient pointer installation positioning is realized.

Mechanism for setting the minute hand of a timepiece with automatic return-to-zero of the seconds hand

The invention relates to a timekeeper, at least having a minute hand, a seconds hand and a clockwork mechanism with a mechanism for adjusting the minute hand. The mechanism comprises an adjusting shaft moving between a conventional position and an adjusting position in an axial direction, the adjusting shaft is coupled with a center-wheel group of the clockwork mechanism such that rotation of theshaft adjusts the minute hand. The adjusting shaft co-operates with a zeroing mechanism, the zeroing mechanism drives the second hand in a zero position when the adjusting shaft moves in the axial adjusting position and locks the seconds hand in the zero position when the adjusting shaft is in the adjusting position, and releases the seconds hand when the adjusting shaft moves in the conventionalposition again. According to the invention, the center-wheel group of the clockwork mechanism has a lock mechanism, the lock mechanism can obtain 60 locking positions, so that the minute hand can move among 60 positions the minute hand by rotating the adjusting shaft in the adjusting position, and each of 60 positions corresponds one minute scale.

Time-display instant switching mechanism

ActiveCN102914959AImprove travel time accuracyEnergy does not decreaseGearworksEscapementsEnergy transferGear drive
The invention relates to a time-display instant switching mechanism which comprises a unit escapement fork, a second wheel, a unit case, a unit escapement wheel, a unit hair spring and a unit gear. The unit case, the unit escapement wheel, the unit hair spring and the unit gear are coaxially arranged, the unit case and the unit escapement wheel are coaxially connected, a gap is reserved between a revolving shaft of the unit gear and a revolving shaft of the unit case, one end of the unit hair spring is connected with the unit escapement wheel, the other end of the unit hair spring is connected with the unit gear, the unit escapement fork is arranged beside the unit escapement wheel, and the second wheel is meshed with a second wheel tooth on a watch and with the unit gear, and is arranged on a poking nail capable of contacting the unit escapement fork during the rotation. Since the hair spring is used for storing energy and combined with an escapement mechanism to achieve instant switching of time display, energy transferred to a balance wheel by a gear driving system is guaranteed against reduction, and travel time precision of a mechanical timekeeper is increased. The time-display instant switching mechanism is small in energy consumption, convenient to achieve and high in reliability, and satisfies the requirement of mass production.

Automatic gas blowing device for eliminating residual engine oil in engine

The invention discloses an automatic gas blowing device for eliminating residual engine oil in an engine. The engine comprises an engine oil adding opening which is provided with an engine oil opening cover. The automatic gas blowing device comprises a compressed gas source, a connector and a controller. The connector comprises a cover-shaped piece used for being arranged on the engine oil adding opening in a covering manner;a first connector penetrates the end face of the cover-shaped piece, and a second connector is connected with the first connector through a gas pipe. The second connector is used for being communicated with the compressed gas source. The controller comprises a timekeeper and an electromagnetic valve. The electromagnetic valve is used for controlling the second connector to be connected or disconnected with the compressed gas source. The timekeeper controls the opening and closing time of the electromagnetic valve. By means of the automatic gas blowing device, the production cost of an engine factory can be reduced, the potential hazard that an automobile factory is stained by residual engine oil when new engine oil is added can be prevented, and the quality of the new engine oil can be ensured.
