Description

TECHNICAL FIELD

[0001] The present application relates to the watch technical field, especially to a watch with left and right hand wearing function. BACKGROUND

[0002] The watch is a portable timing tool, which is designed to be worn on the wrist to display the current time. According to the power source, it can be divided into mechanical watches, quartz watches, solar watches, electronic watches and smart watches. Among them, the mechanical watch is a watch completely driven by mechanical devices, which does not need a battery or any external power supply. Because of its complex mechanical structure and exquisite technology, it is often regarded as an art, and is loved by people.

[0003] The existing mechanical watch is usually designed to be worn on the left hand, which is mainly due to social and cultural habits, ergonomics, and use functions. However, for some specific groups of people or in specific situations, people want to wear watches on the right hand and still be able to use them. However, the structure design of the existing mechanical watch usually cannot meet the needs of left and right hand interchange, and the main reasons are as follows: 1. The existing mechanical watch shaft needs to be directed towards the fingers in order to facilitate the operation of the needle or the repair strip. However, when worn on the right hand, the shaft is located away from the fingers, so there is a problem of inconvenient operation when the needle or the repair strip is operated; 2. When the watch is worn on the right hand and the shaft is directed towards the fingers, the watch dial scale will be reversed by 180°, thereby affecting the user's observation of the current time. Therefore, there is an urgent need for a watch that can be interchanged between left and right hands and can still achieve normal time viewing to solve the above problems. CONTENT OF THE UTILITY MODEL

[0004] In order to solve the problem of the existing watch being unable to normally view the time when interchanged between left and right hands as proposed in the background art, the present application provides a watch with left and right hand wearing function.

[0005] The watch with left and right hand wearing function provided by the present application adopts the following technical solution:

[0006] A watch with left and right hand wearing function, comprising:

[0007] A movement is installed in the watch case, and a coaxial and rotatable hour wheel and minute wheel are provided thereon;

[0008] A dial is installed on the watch case and can rotate relative to the movement, and the dial is provided with a scale;

[0009] The cross wheel assembly is rotatably mounted on the movement, has cross wheel shaft teeth for driving the hour wheel to rotate, and has a cross wheel piece for driving the minute wheel to rotate. The cross wheel shaft teeth are coaxial with the cross wheel piece and can rotate relative to the cross wheel piece. When the cross wheel piece rotates in a first rotation direction, the cross wheel shaft teeth can be driven to rotate synchronously.

[0010] The locking assembly is mounted on the movement and is configured to lock the cross wheel shaft teeth when the cross wheel piece rotates in a second rotation direction, so that the cross wheel piece rotates relative to the cross wheel shaft teeth and the minute wheel rotates alone.

[0011] By adopting the above technical scheme, the scale is arranged on the rotatable dial. When the watch is used with the left hand or the right hand, and the stem is on the finger side, the scale can be adjusted by rotating the dial with the scale, which is convenient and fast. When the cross wheel piece drives the cross wheel shaft teeth to rotate in the first rotation direction, the hour wheel and the minute wheel rotate simultaneously to realize normal time setting. When the cross wheel piece rotates in the second rotation direction, the cross wheel shaft teeth can be locked by the locking assembly, so that the minute wheel can rotate alone. When setting the time, the minute hand rotates alone, thereby avoiding the problem of half-hour position difference of the minute hand after the dial rotates 180°.

[0012] Optionally, the first rotation direction and the second rotation direction are opposite in rotation direction.

[0013] By adopting the above technical scheme, the watch can realize time setting in the first rotation direction and time setting of the minute hand in the second rotation direction, thereby solving the problem of half-hour position difference of the minute hand when the watch is used with the left hand or the right hand. The first rotation direction of the cross wheel piece finally drives the hour hand and the minute hand on the watch to rotate in the clockwise direction, and the second rotation direction of the cross wheel piece finally drives the minute hand on the watch to rotate in the counterclockwise direction.

[0014] Optionally, the cross wheel assembly further comprises:

[0015] The positioning wheel is synchronously connected to the cross wheel shaft teeth and has a plurality of clamping grooves in the circumferential direction thereof;

[0016] The one-way ratchet wheel is synchronously connected to the positioning wheel;

[0017] The positioning spring is fixed to the cross wheel piece and has a protruding portion at the end thereof, which can be clamped in the clamping groove;

[0018] The pressing piece is fixed to the end of the cross wheel shaft teeth and is configured to limit the relative movement of the cross wheel piece and the cross wheel shaft teeth in the axial direction;

[0019] When the cross wheel piece rotates in the first rotation direction, the protruding part on the positioning spring is clamped in the clamping groove, so that the one-way ratchet wheel, the positioning wheel and the cross wheel shaft tooth rotate synchronously with the cross wheel piece.

[0020] By adopting the above technical solution, the protruding part is clamped in the clamping groove, so that the cross wheel piece rotates in the first rotation direction, the one-way ratchet wheel, the positioning wheel and the cross wheel shaft tooth rotate synchronously, the effect of synchronous rotation of the cross wheel piece and the cross wheel shaft tooth is realized, and the purpose of simultaneous rotation of the minute hand and the hour hand is achieved.

[0021] Optionally, the number of clamping grooves is 8, 16 or 24.

[0022] By adopting the above technical solution, the period of the minute hand is limited according to the actual situation, for example, when the number of clamping grooves is 8, the protruding part moves from one clamping groove to an adjacent clamping groove, at this time, one period of rotation of the minute hand is 180°, corresponding to half an hour; when the number of clamping grooves is 16, the protruding part moves from one clamping groove to another clamping groove, one period of rotation of the minute hand is 90°, corresponding to one quarter of an hour; when the number of clamping grooves is 24, the protruding part moves from one clamping groove to another clamping groove, one period of rotation of the minute hand is 60°, corresponding to ten minutes.

[0023] Optionally, the locking assembly comprises:

[0024] The pawl is rotatably installed on the movement;

[0025] The pawl spring is installed on the movement and abuts against one end of the pawl away from the rotation center;

[0026] When the cross wheel piece rotates in the second rotation direction, the pawl can be clamped on the teeth of the one-way ratchet wheel under the action of the pawl spring, so that the one-way ratchet wheel stops rotating, and then the cross wheel shaft tooth stops rotating.

[0027] By adopting the above technical solution, the pawl cooperates with the one-way ratchet wheel, so that when the cross wheel piece rotates in the first rotation direction, the pawl does not lock the one-way ratchet wheel, and the purpose of simultaneous rotation of the minute hand and the hour hand is achieved.

[0028] When the cross wheel piece rotates in the second rotation direction, the pawl can be clamped in the tooth position of the one-way ratchet wheel, thereby limiting the rotation of the one-way ratchet wheel, the positioning wheel and the cross wheel shaft tooth, i.e. limiting the rotation of the hour wheel and the hour hand, only keeping the working effect of the cross wheel piece driving the minute wheel to rotate, i.e. ensuring the independent rotation of the minute hand, so as to solve the problem of position difference of the minute hand in the half hour position after the dial rotates 180°.

[0029] When the pawl locks the one-way ratchet wheel and the cross wheel piece is rotating, the positioning wheel can rotate relative to the positioning spring due to the synchronous rotation connection of the one-way ratchet wheel, the positioning wheel and the cross wheel shaft teeth, at this time, the positioning spring can be elastically deformed, so that the protruding part of the positioning spring is separated from one of the clamping grooves of the positioning wheel and then enters the adjacent other clamping groove, and each time the protruding part enters the clamping groove, there is a click sound and a hand feeling to prompt the angle of rotation of the minute hand.

[0030] Optionally, the cross wheel piece is engaged with the minute wheel.

[0031] By adopting the above technical scheme, the cross wheel piece can directly drive the minute wheel to rotate when rotating.

[0032] Optionally, the cross wheel shaft teeth are engaged with a time passing wheel one installed on the movement, the time passing wheel one is engaged with a time passing wheel two installed on the movement, and the time passing wheel two is engaged with the hour wheel.

[0033] By adopting the above technical scheme, when the cross wheel shaft teeth rotate, power can be sequentially transmitted to the time passing wheel one, the time passing wheel two and then the hour wheel, so as to solve the problem that the cross wheel shaft teeth cannot be directly engaged with the hour wheel due to structural limitations.

[0034] Optionally, the drive assembly further comprises a driving assembly for driving the cross wheel piece to rotate.

[0035] By adopting the above technical scheme, the driving assembly has the effect of driving the cross wheel piece to rotate in the first and second rotation directions, and is mainly used to provide a power source for the movement of the cross wheel piece.

[0036] Optionally, the driving assembly comprises:

[0037] a stem shaft rotatably installed on the movement and extending towards the outside of the movement;

[0038] a clutch wheel installed on the stem shaft;

[0039] a pin wheel rotatably installed on the movement and capable of being engaged with the clutch wheel;

[0040] a pin passing wheel rotatably installed on the movement and engaged with the cross wheel piece and the pin wheel.

[0041] By adopting the above technical scheme, the stem shaft extends outside the movement, and a user can operate it by fingers. The clutch wheel is used to engage with the pin wheel when needed, and then power transmission can be realized through the clutch wheel, the pin wheel and the pin passing wheel after rotating the stem shaft, so as to meet the rotation requirement of the cross wheel piece.

[0042] In summary, the present application includes at least one of the following beneficial technical effects:
