Description

Technical Field

[0001] The present application relates to the technical field of watches, and in particular to a watch capable of being worn on both hands. Background Art

[0002] A watch is a portable timekeeping tool designed to be worn on the wrist to display the current time. According to its power source, it can be divided into mechanical watches, quartz watches, solar watches, electronic watches and smart watches, etc. Among them, a mechanical watch is a watch that is completely driven by a mechanical device. It does not require batteries or any external power source. Because of its complex mechanical structure and exquisite craftsmanship, it is often regarded as a work of art and is loved by people.

[0003] Existing mechanical watches are usually designed to be worn on the left hand, mainly due to social and cultural habits, ergonomics, and usage functions. However, for some specific groups of people or in specific occasions, people hope to be able to use the watch when worn on the right hand, and the structural design of existing mechanical watches usually cannot meet the needs of left-hand and right-hand interchangeability. The main reasons are as follows: 1. The handle of the existing mechanical watch needs to face the finger direction to facilitate operations such as needle alignment or strip patching, but when worn on the right hand, the handle is located on the side away from the finger, so there is an inconvenience in operating when aligning the needle or patching the strip; 2. When the watch is worn on the right hand and the handle faces the finger direction, the dial scale of the watch 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 realize normal time viewing when the left and right hands are interchanged to solve the above problems. Summary of the invention

[0004] In order to solve the problem in the above background technology that the existing watches cannot normally check the time when the left and right hands are interchangeable, the present application provides a watch with the function of being worn on both hands.

[0005] The present application provides a watch with left-hand or right-hand wearing function, which adopts the following technical solution: A watch with left-hand or right-hand wearing function, comprising: The movement is installed in the watch case and is provided with an hour wheel and minute wheel which are coaxial and can rotate relative to each other; A dial, which is mounted on the watch case and can rotate relative to the movement, and the dial is provided with scales; A minute wheel assembly is rotatably mounted on the movement, and has minute wheel shaft teeth for driving the hour wheel to rotate, and a minute wheel piece for driving the minute wheel to rotate. The minute wheel shaft teeth are coaxial with the minute wheel piece and can rotate relative to each other. When the minute wheel piece rotates along the first rotation direction, it can drive the minute wheel shaft teeth to rotate synchronously. The locking assembly is installed on the movement and is configured to lock the minute wheel shaft teeth when the minute wheel piece rotates along the second rotation direction, so that the minute wheel piece rotates relative to the minute wheel shaft teeth and the minute wheel rotates alone.

[0006] By adopting the above technical solution, the scale is placed on the rotatable dial, and when the watch is interchanged between the left and right hands and the stem is on the finger side, the scale can be adjusted by rotating the dial with the scale, which is convenient and quick; and when the split wheel piece drives the split wheel shaft teeth to rotate along the first rotation direction, the hour wheel and the minute wheel rotate at the same time to achieve normal hand alignment; when the split wheel piece rotates along the second rotation direction, the split wheel shaft teeth can be locked by the locking assembly, and finally the minute wheel can rotate alone, that is, when aligning the hands, the minute hand rotates alone, thereby avoiding the problem of a half-hour position difference of the minute hand after the dial rotates 180°.

[0007] Optionally, the first rotation direction is opposite to the second rotation direction.

[0008] By adopting the above technical solution, the watch can not only achieve the hand alignment effect in the first rotation direction, but also can align the minute hand separately in the second rotation direction, so as to solve the problem of half-hour position difference of the minute hand when the left and right hands are swapped; wherein, the rotation of the cross-wheel piece in the first rotation direction eventually causes the hour hand and minute hand on the watch to rotate in the clockwise direction, and the rotation of the cross-wheel piece in the second rotation direction eventually causes the minute hand on the watch to rotate in the counterclockwise direction.

[0009] Optionally, the straddle wheel assembly further includes: The positioning wheel is synchronously connected to the cross-wheel shaft teeth and has a plurality of slots in the circumferential direction; A one-way ratchet wheel, which is synchronously rotated and connected to the positioning wheel; A positioning spring is fixed on the straddle wheel and has a protrusion at its end that can be clamped in the clamping groove; A pressing plate, fixed to the end of the cross-wheel shaft tooth, is configured to limit the relative movement of the cross-wheel plate and the cross-wheel shaft tooth in the axial direction; When the mini-wheel piece rotates along the first rotation direction, the protrusion on the positioning spring is clamped in the clamping groove, so that the one-way ratchet, the positioning wheel and the mini-wheel shaft teeth rotate synchronously with the mini-wheel piece.

[0010] By adopting the above technical solution, the structure in which the protrusion is clamped in the clamping groove can be utilized, so that when the cross-wheel piece rotates in the first rotation direction, the one-way ratchet, the positioning wheel and the cross-wheel shaft teeth are driven to rotate together, thereby achieving the effect of synchronous rotation of the cross-wheel piece and the cross-wheel shaft teeth, and then achieving the purpose of simultaneous rotation of the minute hand and the hour hand.

[0011] Optionally, the number of the card slots is 8, 16 or 24.

[0012] By adopting the above technical solution, the cycle of individual adjustment of the minute hand can be limited according to actual conditions. For example, when the number of slots is 8, after the protrusion moves from one slot to the adjacent slot, the minute hand rotates for a cycle of 180°, corresponding to half an hour; when the number of slots is 16, the protrusion moves from one slot to another, and the minute hand rotates for a cycle of 90°, corresponding to a quarter of an hour; when the number of slots is 24, the protrusion moves from one slot to another, and the minute hand rotates for a cycle of 60°, corresponding to ten minutes.

[0013] Optionally, the locking assembly includes: A pawl, which is rotatably mounted on the movement; A pawl spring, which is mounted on the movement and abuts against an end of the pawl away from the rotation center; When the mini-wheel plate rotates along the second rotation direction, the pawl can be clamped on the teeth of the one-way ratchet under the action of the pawl spring, so that the one-way ratchet stops rotating, and then the mini-wheel shaft teeth stop rotating.

[0014] By adopting the above technical solution, the pawl cooperates with the one-way ratchet, so that when the cross-wheel plate rotates along the first rotation direction, the pawl will not lock the one-way ratchet, thereby achieving the purpose of simultaneous rotation of the minute hand and the hour hand.

[0015] When the mini-wheel piece rotates along the second rotation direction, the pawl can be stuck in the tooth position of the one-way ratchet, thereby limiting the rotation of the one-way ratchet, the positioning wheel, and the mini-wheel shaft teeth, that is, limiting the rotation of the hour wheel and the hour hand, and only retaining the working effect of the mini-wheel piece driving the minute wheel to rotate, that is, ensuring that the minute hand rotates alone, so as to solve the problem of a half-hour position difference of the minute hand after the dial rotates 180°.

[0016] When the pawl locks the one-way ratchet and the cross-wheel piece is rotating, the one-way ratchet, the positioning wheel and the cross-wheel shaft teeth are connected to rotate synchronously, so the positioning wheel can rotate relative to the positioning spring. At this time, the positioning spring can produce elastic deformation, so that the protrusion of the positioning spring disengages from one of the slots of the positioning wheel and then enters another adjacent slot. Each time the protrusion enters the slot, there will be a clicking sound and a feel, which is used to indicate the rotation angle of the minute hand.

[0017] Optionally, the minute wheel piece is meshed with the minute wheel.

[0018] By adopting the above technical solution, the step wheel piece can directly drive the minute wheel to rotate when it rotates.

[0019] Optionally, the cross-wheel shaft teeth are meshed with a time wheel 1 installed on the movement, the time wheel 1 is meshed with a time wheel 2 installed on the movement, and the time wheel 2 is meshed with the hour wheel.

[0020] By adopting the above technical solution, when the step wheel shaft teeth rotate, power can be transmitted to the hour wheel one and the hour wheel two in sequence, and then the power can be transmitted to the hour wheel, so as to solve the problem that the step wheel shaft teeth cannot directly mesh with the hour wheel due to structural limitations.

[0021] Optionally, a drive assembly for driving the cross-wheel piece to rotate is also included.

[0022] By adopting the above technical solution, the driving component has the effect of driving the cross-wheel piece to rotate along the first rotation direction and the second rotation direction, and is mainly used to provide a power source for the movement of the cross-wheel piece.

[0023] Optionally, the driving component includes: A stem, which is rotatably mounted on the movement and has one end extending toward the outside of the movement; A clutch wheel, which is mounted on the stem; The needle wheel is rotatably mounted on the movement and can mesh with the clutch wheel; The needle setting wheel is rotatably mounted on the movement and is respectively meshed with the step-wheel piece and the needle setting wheel.

[0024] By adopting the above technical solution, the stem is extended outside the movement, and the user can operate it with his fingers. The clutch wheel is used to engage with the needle wheel when needed. After rotating the stem, power can be transmitted through the clutch wheel, the needle wheel, and the needle wheel to meet the rotation requirements of the cross-wheel.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: (1) The present invention has a reasonable design structure and is easy to operate. It can solve the problem of the scale being reversed and the minute hand being misplaced when the stem is worn on the left or right hand facing the finger side, and can realize the function of multiple wearing modes of the watch. (2) The present invention is provided with a minute wheel assembly, which can realize the common rotation of the hour wheel and the minute wheel when rotating in the first rotation direction, satisfying the function that the minute hand rotates one circle and the hour hand rotates one grid under normal circumstances; and can also use the pawl to limit the rotation of the minute wheel shaft teeth when rotating in the second rotation direction, so that the minute wheel piece rotates alone, and the minute wheel and the minute hand on the watch rotate alone, thereby solving the problem of 180° position difference of the minute hand after the left and right hands are interchanged.

[0028] The present application is further described in detail below in conjunction with the accompanying drawings.

[0029] like Figure 1-7 As shown, the embodiment of the present application discloses a watch with left and right hand wearing function, comprising: The movement 12 is installed in the watch case, and is provided with a coaxial hour wheel 5 and a minute wheel 6 that can rotate relative to each other. The hour wheel 5 and the minute wheel 6 are sleeved and connected to each other and are respectively provided with an hour hand and a minute hand. In this example, the hour wheel 5 and the minute wheel 6 are located at the center of the movement 12 and can rotate relative to the movement 12. A dial 13, which is mounted on the watch case and can rotate relative to the movement 12, and is provided with scales 1301, wherein the scales 1301 are evenly distributed around the center of the dial 13, and the scales 1301 can be Roman numerals, Arabic numerals, bar or dot scales 1301, etc., which are not specifically limited here; Among them, in this example, the movement 12 and the dial 13 are both installed on the watch case, the movement 12 is installed inside the case, and is fixedly connected to the case; the dial 13 is also called the face plate (in the prior art, the dial 13 is installed on the movement). In this embodiment, the dial 13 is rotatably installed on the case. The purpose is to enable the dial 13 to rotate relative to the movement 13. When the dial 13 rotates, the scale 1301 thereon rotates together, so that the watch can still indicate the time after the left and right hands are swapped.

[0030] The minute wheel assembly 1 is rotatably mounted on the movement 12, and has a minute wheel shaft tooth 104 for driving the hour wheel 5 to rotate, and a minute wheel piece 101 for driving the minute wheel 6 to rotate. The minute wheel shaft tooth 104 is coaxial with the minute wheel piece 101 and can rotate relative to it. When the minute wheel piece 101 rotates along the first rotation direction, it can drive the minute wheel shaft tooth 104 to rotate synchronously; The locking assembly is mounted on the movement 12 and is configured to lock the minute wheel shaft teeth 104 when the minute wheel 101 rotates in the second rotation direction, so that the minute wheel 101 rotates relative to the minute wheel shaft teeth 104 and the minute wheel 6 rotates alone.

[0031] Specifically, the first rotation direction is opposite to the second rotation direction, so that the stem 4 is in the needle position in both rotation directions. The first rotation direction can adjust the time, and the second rotation direction is used to correct the misalignment angle of the minute hand.

[0032] Specifically, the straddle wheel assembly 1 further includes: The positioning wheel 105 is synchronously connected to the cross-wheel shaft gear 104, and has a plurality of slots 1051 in the circumferential direction thereof. The number of the slots 1051 is 8, 16 or 24. In this example, the number of the slots 1051 is 8, so that after the protrusion 1021 moves from one slot 1051 to another adjacent slot 1051, the minute hand rotates exactly 180°. The one-way ratchet 103 is synchronously connected to the positioning wheel 105. In this example, the one-way ratchet 103, the positioning wheel 105 and the cross-wheel shaft gear 104 are fixedly connected. The positioning wheel 105 is installed on the cross-wheel shaft gear 104 by riveting, and the one-way ratchet 103 can be installed on the positioning wheel 105 by interference fit. Alternatively, other fixed connection methods can be used between the three, mainly to form an integral structure that can rotate synchronously. The positioning spring 102 is fixed on the intermediate wheel 101, and a protrusion 1021 that can be clamped in the clamping groove 1051 is provided at its end. In this example, the positioning spring 102 and the intermediate wheel 101 are riveted together as a whole, and the intermediate wheel 101 can drive the positioning spring 102 to rotate; The pressing piece 106 is fixed to the end of the cross-wheel shaft tooth 104 and is configured to limit the relative movement of the cross-wheel piece 101 and the cross-wheel shaft tooth 104 in the axial direction, thereby preventing the cross-wheel piece 101 from falling off the cross-wheel shaft tooth 104; When the mini-wheel piece 101 rotates along the first rotation direction, the protrusion 1021 on the positioning spring 102 is clamped in the clamping groove 1051 , so that the one-way ratchet 103 , the positioning wheel 105 and the mini-wheel shaft teeth 104 rotate synchronously with the mini-wheel piece 101 .

[0033] Specifically, the locking assembly comprises: The pawl 2 is rotatably mounted on the movement 12, specifically, mounted on the movement 12 via a pin; The pawl spring 3 is installed on the movement 12 and abuts against the end of the pawl 2 away from the rotation center. When working, it can apply a force to the pawl 2 so that the pawl 2 is always in contact with the one-way ratchet 103. When the mini-wheel plate 101 rotates along the first direction, the one-way ratchet 103 and the pawl 2 are in a state of relative slippage. The positioning spring 102 can push the positioning wheel 105 so that the mini-wheel shaft teeth 104 can rotate with the mini-wheel plate 101; when the mini-wheel plate 101 rotates along the second rotation direction, the pawl 2 can be clamped on the teeth of the one-way ratchet 103 under the action of the pawl spring 3, so that the one-way ratchet 103 stops rotating, and then the mini-wheel shaft teeth 104 stop rotating.

[0034] Specifically, the minute wheel plate 101 meshes with the minute wheel 6; the minute wheel shaft teeth 104 mesh with the hour wheel 10 installed on the movement 12, the hour wheel 10 meshes with the hour wheel 2 11 installed on the movement 12, and the hour wheel 2 11 meshes with the hour wheel 5.

[0035] Specifically, it also includes a driving assembly for driving the cross-wheel piece 101 to rotate, and the driving assembly includes: A stem 4 is rotatably mounted on the movement 12 and has one end extending toward the outside of the movement 12; A clutch wheel 7, which is mounted on the stem 4; The setting wheel 8 is rotatably mounted on the movement 12 and can mesh with the clutch wheel 7; The needle setting wheel 9 is rotatably mounted on the movement 12 and is meshed with the intermediate wheel 101 and the needle setting wheel 8 respectively; When in use, the stem 4 can be pulled outward along its own axis, driving the clutch wheel 7 to mesh with the needle setting wheel 8, and then rotating forward or reversely to achieve the needle setting function. The clutch wheel 7 is sleeved on the stem 4, and the structure and working principle of driving the clutch wheel 7 to move after the stem 4 is pulled out are conventional design means in the prior art, and will not be described in detail here.

[0036] like Figure 7 As shown, it is a schematic diagram of the working principle of this embodiment, and its working principle is: Initial state a, which is the state of wearing on the left hand, with the stem 4 at the right position as shown in the figure; State b, at this time, the movement 12 rotates 180°, and the stem 4 is at the left position in the figure, which is suitable for right-handed wear, and is convenient for the left hand to perform needle adjustment or strip repair operations, but at this time, the dial 13 and the scale 1301 are in an upside-down state after the movement 12 rotates 180°, which is not conducive to checking the time; State c, at this time, the dial 13 is manually rotated 180°, and the scale 1301 on the dial 13 is adjusted to the normal state, but the pointer is deviated. Through the traditional means (normal needle adjustment operation, that is, the cross-wheel piece 101 and the cross-wheel shaft tooth 104 rotate synchronously), the hour hand can only be adjusted to the time in the initial state, and the minute hand is 180° different from the accurate time, that is, half an hour; State d, at this time, the minute hand is adjusted to the precise position in the initial state by aligning the minute hand alone (that is, the stem 4 drives the cross-wheel piece 101 to rotate along the second rotation direction, the pawl 2 is used to lock the one-way ratchet 103, the hour wheel 5 does not move, and the minute wheel 6 rotates alone). After the left and right hands are exchanged, the watch time is accurate and the time can be checked normally.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
