[0033] Example

[0034] like Figure 1-6 As shown, a preferred embodiment of a hand-pull timer provided by the present invention includes a housing 1; a timing movement 5, which is connected to the housing 1 and realizes unit timing through a built-in vibration system or a single-chip computer system; it also includes a linkage component 2, one end of which is connected to the timing movement 5 and can be driven to rotate by the timing movement 5; a pull rope component 3, including a rope body 31, and the other end of the pull rope component 3 is connected to the linkage component 2; the rope body 31 has at least one thread head 32, and the thread head 32 is exposed from the housing 1. Pulling the thread head 32 can drive the linkage component 2 to rotate, so that the timing movement 5 sets the timing duration.

[0035] Specifically, the timing movement 5 is installed in the housing 1 and is in transmission connection with one end of the linkage assembly 2. The linkage assembly 2 can be installed in the housing 1, and the pull rope assembly 3 is inserted into the housing 1 and then connected to the other end of the linkage assembly 2. Alternatively, one end of the linkage assembly 2 is exposed outside the housing 1, and the pull rope assembly 3 is connected to the exposed end, and the other end of the linkage assembly 2 is inserted into the housing 1 and is in transmission connection with the timing movement 5.

[0036] The connection between the pull rope assembly 3 and the linkage assembly 2 can be achieved by, for example, connecting the pull rope to the linkage assembly 2 through a sleeve with teeth or a similar transmission structure, or by directly wrapping the pull rope around the linkage assembly 2. This embodiment is described using the former as an example.

[0037] The timing movement 5 is preferably a movement with a vibration system inside, which can be a mechanical clockwork movement, a quartz movement, or an electronic movement. The angle sensing unit in the built-in single-chip circuit system identifies the angle of the rotating shaft and matches the corresponding duration, and the stepper motor drives the pointer to rotate; the timing method can be countdown or countup; the timing movement 5 can be any movement that can be driven by the rotation of the rotating shaft to realize the timing function. There are many mature solutions for these movements in the field of timing instruments, which will not be described here. The focus of this solution is to replace the traditional boring timing operation with the rope timing method, increase the fun of timing, and use the rope body 31 to visualize the invisible time, so that users can intuitively feel the passage of time, thereby cultivating the concept of cherishing time.

[0038] In order to further enhance the user experience, facilitate the timing operation, and achieve faster and more accurate timing, the rope body 31 has a first line head and a second line head, which respectively represent the increase and decrease of the duration; when customizing the duration, pulling the first line head can drive the linkage component 2 to rotate in a first direction, such as clockwise, so that the timing movement 5 increases the timing duration, and pulling the second line head can drive the linkage component 2 to rotate in the opposite direction of the first direction, such as counterclockwise, so that the timing movement 5 decreases the timing duration. In some other simple replacement embodiments, the counterclockwise direction can also be defined as the direction of increasing the timing.

[0039] The spacing between adjacent time marks is set in a certain ratio to the arc of the linkage component 2, so that the time mark can correspond to the customized duration. For example, a rope length of one centimeter corresponds to an arc of the linkage component 2, and the length is defined as ten minutes.

[0040] Furthermore, a plurality of time marks are arranged on the rope body 31 along the length direction, which are suitable for guiding the customization of the duration and / or displaying the remaining duration.

[0041] Furthermore, the rope body 31 is divided into several rope segments by duration marks; adjacent rope segments are marked with different colors and / or symbols, so that the duration information can be intuitively observed during the duration customization process or the timing process.

[0042] Furthermore, the pull rope assembly 3 includes multiple groups of rope bodies 31, each group of rope bodies 31 is connected to the linkage assembly 2, and the multiple groups of rope bodies 31 represent different timing durations, which are suitable for fast timing; different rope bodies 31 are distinguished by their respective lengths, colors, radial cross-sections, or symbol identifications, or different symbol identifications or colors are set at the positions of different rope bodies 31 corresponding to the shell 1, so that different rope bodies 31 represent different timing durations.

[0043] In this embodiment, the rope body 31 is provided with four groups, representing 5 minutes, 10 minutes, 15 minutes, and 30 minutes respectively; the rope body 31 as a whole adopts a lighter saturation color, namely light blue, light cyan, light yellow, and light pink; the color between the rope segments adopts a darker saturation color, such as dark green, dark blue, dark red, black, etc.

[0044] Furthermore, different groups of rope bodies 31 have different rope outlet directions on the housing 1 , thereby reducing interference between groups of rope bodies 31 and being able to further quickly distinguish and select different rope bodies 31 .

[0045] In some other embodiments, the pull rope assembly 3 further includes a sleeve, which is sleeved on the linkage assembly 2, and when the sleeve rotates, the linkage assembly 2 can be driven to rotate; the sleeve is provided with a wire groove; the wire groove is independently provided, and one wire groove corresponds to receiving a rope body 31. Preferably, a nearly closed wire groove is provided on the sleeve, and two front and rear wire outlets are provided, respectively allowing the first wire end and the second wire end to pass through the sleeve.

[0046] The linkage assembly 2 includes a main transmission shaft 21, one end of which is transmission-connected to the movement assembly; a plurality of planetary shafts 22, which are distributed circumferentially along the main transmission shaft 21, and the planetary shafts 22 are transmission-connected to the other end of the main transmission shaft 21; a pull rope assembly 3 is connected to the planetary shafts 22; the planetary shafts 22 are unidirectionally transmission-connected to the main transmission shaft 21, or the planetary shafts 22 are slidingly arranged, and the planetary shafts 22 and the main transmission shaft 21 can be clutched and transmitted by sliding.

[0047] In this embodiment, the planetary shaft 22 is coupled and coupled with the main transmission shaft 21 by sliding. Preferably, the transmission between the planetary shaft 22 and the main transmission shaft 21 is a meshing transmission.

[0048] Specifically, a plurality of sliding parts 111 are arranged on the housing 1, which are distributed circumferentially along the main transmission shaft 21 and are arranged corresponding to the planetary shafts 22, suitable for making the planetary shafts 22 slidably connected to the housing 1; the planetary shaft 22 includes a shaft body portion 221, which is rotatably connected to the sliding part 111, and can slide in the sliding part 111 or be led by the sliding part 111; a toothed portion 222, which is arranged on the shaft body portion 221 and is suitable for transmission connection to the main transmission shaft 21; and / or a wire groove portion 223, which is suitable for accommodating the rope body 31.

[0049] Furthermore, a first clamping portion is provided on the shaft body 221; a second clamping portion is provided on the sliding portion 111, which is located at one end close to the main transmission shaft 21 and cooperates with the first clamping portion to keep the planetary shaft 22 in transmission connection with the main transmission shaft 21. Preferably, the second clamping portion is a spherical convex point or an arc-shaped protrusion (not shown in the figure). When in use, the first clamping portion is squeezed through the second clamping portion by external force intervention, so that the planetary shaft 22 is restricted to one end close to the main transmission shaft 21, so that the two maintain transmission connection.

[0050] In this embodiment, a linkage mounting plate 11 is provided in the middle of the housing 1, and the sliding portion 111 is provided on the linkage mounting plate 11. The sliding portion 111 may be a long hole as in this embodiment, or may be a combination of a slider and a slide rail, wherein the slide rail is provided on the housing 1, the slider is connected to the slide rail, and the shaft portion 221 is rotatably connected to the slider. The wire groove portion 223 is provided at one end of the shaft portion 221 away from the chronograph movement 5. In some embodiments with poor effects, the wire groove portion 223 may not be provided.

[0051] In this embodiment, the end of the shaft body 221 of the planetary shaft 22 away from the timing movement 5 is exposed outside the housing 1. Specifically, a through hole 12 is set on the outer wall of the housing 1. It is a long hole, and its length direction is consistent with the long hole of the sliding part 111. The shaft body 221 passes through and is exposed above the long hole on the outer wall of the housing 1. The purpose is to manually rewind the rope 31 and reset it, especially when the planetary shaft 22 is separated from the main transmission shaft 21 without the subjective will of the user. In some further optimized embodiments, the planetary shaft 22 also includes an operating part 224, which is located outside the housing 1 and is suitable for manually rewinding and resetting the rope 31. The simplest implementation is that the shaft body 221 is exposed as in this embodiment; preferably, the operating part 224 is in the shape of a non-cylindrical knob-like structure. In this embodiment, a chamfer is set on the shaft body 221, so that the operating part 224 is formed at the exposed end.

[0052] Furthermore, a limiting portion is provided on the housing 1 , which is suitable for limiting the wire head 32 from being retracted into the housing 1 .

[0053] In this embodiment, the housing 1 includes a bottom shell and a front shell, which are connected to form an installation space. The linkage mounting plate 11 is arranged on the bottom shell, on a side close to the front shell, or the linkage mounting plate 11 is arranged on the front shell, on a side close to the bottom shell. The timing movement 5, the linkage assembly 2, and the pull rope assembly 3 are basically located in the above-mentioned installation space. A plurality of rope outlet holes 13 are arranged on the outer wall of the housing 1, and the number of the rope pull rope assemblies 3 is the same. The rope body 31 passes through the rope outlet holes 13 so that the wire head 32 can be exposed outside the housing 1; the rope outlet hole 13 of each rope pull rope assembly 3 is arranged separately, which can further reduce the use interference between different groups of rope bodies 31 and optimize the use experience.

[0054] Furthermore, it also includes a reminder component, connected to the wire head 32 or the housing 1; the reminder component has a trigger switch, which is arranged corresponding to the limit part or the wire head 32. Specifically, the reminder component can be arranged on the housing 1, and the trigger switch is located on the housing 1 for the rope. When the wire head 32 touches the limit part, the reminder component can be triggered to send a reminder signal, and the reminder signal includes but is not limited to light, sound and smell, which is used to remind the user that the timing has ended. In this embodiment, the limit part is integrated on the rope outlet hole 13.

[0055] Furthermore, it also includes a time display part, which is suitable for real-time display of timing information (convenient for setting the timing duration), and the time display part has a pointer or a progress piece, which is connected to the linkage component 2 and rotates with the linkage component 2, and / or a scale 4, which is distributed on the housing 1 along the circumference of the main transmission shaft 21. In this embodiment, the time display part is a progress piece, which is connected to the main transmission shaft 21 and rotates with the main transmission shaft 21; the scale 4 is arranged on the outer wall of the housing 1 through the scale 4 piece, and an opening is opened on the scale 4 piece for the progress piece to be rotated in or out.

[0056] The hand-pull timer of the present invention transmits the driving force of the pull rope assembly to the timing movement by setting a linkage component. The timing duration can be customized by pulling the wire head, which increases the fun of the timer and improves the user's willingness to use the product. In addition, the abstract time duration can be visualized by the length of the pull rope, thereby strengthening the phenomenon of time passing and cultivating the user's concept of cherishing time.

[0057] The above embodiments only express a part of the implementation methods of the present invention. A number of modifications, substitutions and improvements made by those skilled in the art without departing from the concept of the present invention without creative work all fall within the protection scope of the present invention.
