[0002] As a timekeeping tool, timers are widely used. There are many types of timers, such as clocks, mechanical watches, electronic watches, etc. In order to accurately time, existing timers often use minute hands and second hands to display time. However, when users read the time, they need to correspond to the numbers on the dial, and due to the relatively complex mechanical structure, timing is prone to errors. If an electronic digital display method is used, a battery is required for power supply, and the battery needs to be replaced or charged frequently, which is very troublesome for long-term use.

[0032] In the description of this embodiment, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0033] Please refer to Figure 1-8 , the embodiment of the present application provides a timer 100, including a dial 1, an indicating arm 2 and a base 3. The dial 1 and the indicating arm 2 are both mounted on the base 3.

[0034] In this embodiment, the base 3 includes a bottom plate 31, and the bottom plate 31 is mainly used to support and install the components of the timer 100.

[0035] In this embodiment, the base 3 further includes a carrier plate 39. The bottom plate 31 has a groove matching the outer contour of the carrier plate 39, and the carrier plate 39 is mounted in the groove 311.

[0036] In this embodiment, the base 3 further includes a drive shaft 37. There is a through hole in the middle of the bottom plate 31. One end of the drive shaft 37 is fixed to the through hole, and the carrier plate 39 can selectively rotate around the drive shaft 37 under the guidance of the groove 311.

[0037] In this embodiment, a gear is fixed to one end of the drive shaft 37. A power source such as a motor drives the drive shaft 37 to rotate through the gear to provide driving force for the drive shaft 37. It can be understood that in some embodiments, the power source can be of other types, and the gear can also be changed to other transmission forms as long as it can drive the drive shaft 37 to move.

[0038] In this embodiment, the indicating arm 2 includes two clock blocks 21 arranged opposite to each other, and the clock blocks are used to indicate the hour number.

[0039] In this embodiment, the indicating arm 2 further includes a second bracket 23 and a cover assembly 22. The second bracket 23 is disposed corresponding to the drive shaft 37. The second bracket 23 is provided with a through hole at a position corresponding to the drive shaft 37. The other end of the drive shaft 37 passes through the through hole and is fixedly connected to the cover assembly 22. In this way, the second bracket 23 is fixed to the drive shaft 37. When the drive shaft 37 rotates, the second bracket 23 rotates with the drive shaft 37, so that the indicating arm 2 rotates with the drive shaft 37.

[0040] In this embodiment, the second bracket 23 includes a first fastener 232. The other end of the drive shaft 37 is fixedly connected to the drive shaft 37 through the first fastener 232. Specifically, the first fastener 232 can be a screw, a bolt, a rivet, etc., but is not limited thereto. In this way, the second bracket 23 is stably fixedly connected to the drive shaft 37.

[0041] In this embodiment, the indicating arm 2 includes two first connecting columns 24 disposed opposite to each other. Both of the two first connecting columns 24 are located on the side of the second bracket 23 facing the carrier plate 39 and are distributed on both sides of the clock block 21.

[0042] In this embodiment, the second bracket 23 further includes two second mounting holes 231. The two second mounting holes 231 are respectively disposed corresponding to the two first connecting columns 24. The two first connecting columns 24 are respectively snapped into the two second mounting holes 231. In this way, the first connecting column 24 is fixedly connected to the second bracket 23.

[0043] In this embodiment, the carrier plate 39 respectively has one first groove 36 at positions corresponding to the two first connecting columns 24. The first connecting column 24 is received in the first groove 36. In this way, the second bracket 23 can be rotated with the rotation of the carrier plate 39 under the push of the first groove 36.

[0044] In this embodiment, the second bracket 23 includes two second hollow portions 234 distributed on both sides of the cover assembly 22 and arranged oppositely, and two second shaft members 233. The two second hollow portions 234 respectively correspond to the two clock blocks 21. The two second shaft members 233 are respectively located in the two second hollow portions 234. At the second inner walls 236 corresponding to the two ends of the second shaft member 233 in the second hollow portion 234, there is respectively one bayonet 235. The two clock blocks 21 are also respectively located in the two second hollow portions 234 and are rotatably mounted on the corresponding second shaft members 233. Specifically, the clock block 21 is provided with a second shaft hole 215 corresponding to the second shaft member 233. One end of the second shaft member 233 is clamped in its corresponding bayonet 235, and the other end of the second shaft member 233 passes through the second shaft hole 215 and is clamped in its corresponding bayonet 235. In this way, the second shaft member 233 is fixedly connected to the second inner wall 236 of the second hollow portion 234, and the clock block 21 is rotatably connected to the second shaft member 233. When the second bracket 23 rotates with the drive shaft 37, the clock block 21 rotates around the drive shaft 37.

[0045] In this embodiment, the clock block 21 includes a second gear 211 and a second block body 214. The second gear 211 is fixed to the second block body 214. The second block body 214 and the second gear 211 are both rotatably connected to the second shaft member 233. In this way, the second gear 211 rotates around the second shaft member 233, thereby driving the clock block 21 to rotate around the second shaft member 233.

[0046] In this embodiment, the base 3 is correspondingly provided with a guide ring 310 at a position close to the rotation path of the second gear 211. The guide ring 310 has a second guide surface 35 arranged close to and along the rotation path of the second gear 211.

[0047] In this embodiment, there is a second protrusion 38 on the second guide plane 35 located on the rotation path of the second gear 211. The second gear 211 has a plurality of second tooth grooves 212. When the second gear 211 rotates around the drive shaft 37 and passes through the second protrusion 38, the second protrusion 38 extends into the second tooth groove 212 facing and closest to the second protrusion 38. In this way, driven by the rotational movement of the second gear 211 around the drive shaft 37, the second gear 211 rotates around the second shaft member 233, thereby driving the entire clock block 21 to rotate around the second shaft member 233.

[0048] In this embodiment, the second block body 214 has a second digital surface 213, and hour numbers are engraved on the second digital surface 213. In this way, the clock block 21 can be used to indicate the hour numbers.

[0049] In this embodiment, the projection of the clock block 21 on a plane perpendicular to the axial direction of the second shaft member 233 is a regular hexagon. The clock block 21 has only 6 second digital surfaces 213. The 6 second digital surfaces 213 of one of the two clock blocks 21 are respectively engraved with the hour numbers 1, 3, 5, 7, 9, and 11, and the 6 second digital surfaces 213 of the other are respectively engraved with the hour numbers 2, 4, 6, 8, 10, and 12.

[0050] In this embodiment, the dial 1 includes 13 minute blocks 11, which are respectively used to indicate the minute numbers 00, 05, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 00. The 13 minute blocks 11 are distributed in a semi-circular shape around the indicating arm 2 and form a semi-circular area for displaying minutes. The second protrusion 38 is located on the opposite side opposite to the minute block 11 indicating the minute number 30.

[0051] In this embodiment, the dial 1 further includes a first bracket 12. The first bracket 12 has a first mounting hole 121. The bottom plate 31 is provided with a second connecting column 34 corresponding to the first mounting hole 121. The second connecting column 34 is clamped in the first mounting hole 121. In this way, the first bracket 12 is fixedly connected to the bottom plate 31.

[0052] In this embodiment, the first bracket 12 includes a first through hole 125 corresponding to the indicating arm 2. The indicating arm 2 is located in the first through hole 125. In this way, the indicating arm 2 can have enough space to rotate with the driving shaft 37.

[0053] In this embodiment, the first bracket 12 further includes a first hollow-out 123 along the peripheral direction around the first through hole 125 and corresponding to the minute blocks 11, and 13 first shaft members 122 respectively corresponding to the 13 minute blocks 11. The 13 first shaft members 122 are all located in the first hollow-out 123. At the first inner walls 126 corresponding to the two ends of the first shaft member 122, each has a third shaft hole 124. The 13 minute blocks 11 are also all located in the first hollow-out 123 and are respectively rotatably mounted on the corresponding first shaft members 122. Specifically, the minute block 11 is provided with a first shaft hole 115 corresponding to the first shaft member 122. One end of the first shaft member 122 is clamped in its corresponding third shaft hole 124, and the other end of the first shaft member 122 passes through the first shaft hole 115 and is clamped in its corresponding third shaft hole 124. In this way, the first shaft member 13 is fixedly connected to the first inner wall 126 of the first hollow-out 123, and the minute block 11 is rotatably connected to the first shaft member 122.

[0054] In this embodiment, the minute block 11 includes a first gear 111 and a first block 114. The first gear 111 is fixed to the first block 114, and both the first block 114 and the first gear 111 are rotatably connected to a first shaft member 122. Thus, the first gear 111 rotates around the first shaft member 122 to drive the first block 114 to rotate around the first shaft member 122.

[0055] In this embodiment, one side of the carrier plate 39 facing the first gear 111 has a first guiding surface 33 that is close to and faces the first gear 111. The first guiding surface 33 is annular and extends along the distribution direction of the first gear 111. One side of the annular first guiding plane 33 corresponding to a clock block 21 has a pair of adjacent first protrusions 32, and the other side of the annular first guiding plane 33 corresponding to another clock block 21 has another pair of adjacent first protrusions 32. By adjusting the rotation angle of the carrier plate 39, two adjacent first protrusions 32 can be adjusted to correspond to any two adjacent first gears 111 among the 13 first gears 111.

[0056] In this embodiment, the first gear 111 has a plurality of first tooth grooves 112. When the first protrusion 32 rotates around the drive shaft 37 with the carrier plate 39 and passes by the first gear 111, the first protrusion 32 extends into the first tooth groove 112 that faces and is closest to the first guiding plane 33. Thus, driven by the rotational movement of the carrier plate 39 around the drive shaft 37, the first gear 111 rotates around the first shaft member 122, thereby driving the entire minute block 11 to rotate around the first shaft member 122.

[0057] In this embodiment, the projection of the minute block 11 on a plane perpendicular to the axial direction of the first shaft member 122 is a square. The minute block 11 has 4 first digital surfaces 113, and the same minute numbers are engraved on two opposite first digital surfaces 113 among the 4 first digital surfaces 113. Thus, the minute block 11 can be used to indicate the minute numbers.

[0058] Please refer to Figure 9 and Figure 10When in use, when the clock block 21 indicating the hour number n rotates from the vicinity of the minute block 11 indicating the minute number 00 at the starting position of the semicircular area displaying the minute to enter the semicircular area displaying the minute, the other clock block 21 arranged opposite to the clock block 21 indicating the hour number n indicates the hour number n-1; under the action of the driving shaft 37, the indicating arm 2 rotates with the driving shaft 37, driving the carrier plate 39 fixed to the second bracket 23 to rotate, and a pair of adjacent first protrusions 32 corresponding to the clock block 21 indicating the hour number n rotates with the carrier plate 39, and when the clock block 21 indicating the hour number n rotates to gradually indicate the hour number n-1, the indicating arm 2 rotates with the driving shaft 37, driving the carrier plate 39 fixed to the second bracket 23 to rotate, and the pair of adjacent first protrusions 32 corresponding to the clock block 21 indicating the hour number n rotates with the carrier plate 39. When the minute block 11 indicating the minute number is mm, one of the pair of adjacent first protrusions 32 gradually extends into the first tooth groove 112 of the first gear 111 corresponding to the minute block 11 indicating the minute number is mm, and the first gear 111 is turned to rotate it until the first digital surface 113 corresponding to the minute block 11 faces upward, so that the minute block 11 indicates the minute number is mm, and the other of the pair of adjacent first protrusions 32 gradually extends into the first tooth groove 112 of the first gear 111 corresponding to the previous minute block 11 indicating the minute number is mm-5 adjacent to the minute block 11 indicating the minute number, so that the minute block 11 rotates to the minute number of mm. The minute block 11 of mm-5 makes the surface of the minute block 11 with the empty display number facing upward, so that the indicated minute number is empty. In this way, only one minute block 11 can always keep the first digital surface 113 facing upward, and the remaining minute blocks 11 keep the surfaces with the empty display numbers facing upward; when the clock block 21 indicating the hour number n rotates to face the minute block 11 indicating the minute number 30, the other clock block 21 indicating the hour number n-1, which is set opposite to the clock block 21 indicating the hour number n, just rotates to the position of the second protrusion 38 on the opposite side of the setting, at this time, the clock block 21 is around the minute block 11 indicating the hour number n. Driven by the rotational movement trend of the driving shaft 37, the second gear 211 rotates around the second shaft 233, thereby driving the clock block 21 to rotate around the second shaft 233 as a whole, and then the clock block 21 indicates the hour number n+1. When the clock block 21 indicating the hour number n rotates away from the semicircular area displaying minutes from the vicinity of the minute block 11 indicating the minute number 00 at the end position of the semicircular area displaying minutes, the clock block 21 indicating the hour number n+1 just rotates from the vicinity of the minute block 11 indicating the minute number 00 at the starting position of the semicircular area displaying minutes to enter the semicircular area displaying minutes.

[0059] The above-mentioned timer 100 is convenient for users to read the time because it displays the time numerically. Since its structure is simple, the timing is not prone to errors. Since it does not require battery power supply, it is convenient for users to use for a long time. Since the indicating arm 2 points to a minute block 11, the minute block 11 shows the minutes it indicates, while the remaining minute blocks 11 are all shown as empty, thus increasing the fun of users' use. Since the first connecting post 24 of the indicating arm 2 is only received in the first groove 36 on the carrier plate 39, but the carrier plate 39 does not bear the weight of the indicating arm 2 in the direction of gravity, the load on the drive shaft 37 can be reduced, thereby increasing the reliability of the drive shaft 37. Since one end of the second shaft member 233 is clamped to its corresponding bayonet 235 by a wedging method similar to a mortise and tenon structure, the problem that the screws are likely to fall off in the solution of screw connection can be avoided, thereby increasing the reliability of the connection.
