Description

Technical Field

[0001] This application relates to the field of perpetual calendars, and particularly to a desktop perpetual calendar. Background Art

[0002] The perpetual calendar is the oldest solar calendar in ancient Chinese legends. A perpetual calendar is a calendar that records the specific solar and lunar dates within a certain time range (such as 100 years or more), which is convenient for people in need to query and use. The term "ten thousand years" is just a symbol, indicating a large time span. There are generally two forms of perpetual calendars. One is the book type, which has many pages and is inconvenient to search; the other is the turntable type, which is more convenient to use. With the progress of society and the improvement of consumers' aesthetic needs, the perpetual calendar has gradually become a decorative ornament.

[0003] Currently, Chinese Utility Model Publication No. CN212694683U discloses a desktop perpetual calendar, including an installation disk. An installation groove is provided on the installation disk, a scale disk is rotatably installed in the installation groove, multiple scale areas are provided on the scale disk, a viewing window disk is further provided on the installation disk, multiple observation windows are provided on the viewing window disk, and a placement structure is provided on the installation disk. This application has the effect of improving the problem that general perpetual calendars are not easily used as decorative ornaments.

[0004] Since there are multiple scale areas on the scale disk, users can rotate the scale disk according to actual needs to display the date. However, when the user rotates the scale disk, it is easy for the scale area not to coincide well with the observation window, resulting in a long adjustment time for the scale disk and low efficiency in adjusting and displaying the date of the perpetual calendar. Utility Model Content

[0005] In order to facilitate users to adjust the date displayed on the perpetual calendar, this application provides a desktop perpetual calendar.

[0006] A desktop perpetual calendar provided by this application adopts the following technical solution:

[0007] A desktop perpetual calendar includes a base, a scale disk, a viewing window disk, and a locking member. The scale disk is rotatably connected to the base. Multiple scale areas are provided on the scale disk. Multiple observation windows are provided on the viewing window disk. The locking member includes a locking spring and a locking bead. A plurality of locking grooves are provided on the scale disk along the circumferential direction. The locking bead is slidably connected to the base, and the locking spring is used to snap the locking bead into the locking groove.

[0008] By adopting the above technical solution, when a user uses a perpetual calendar and rotates the scale disk, the user can observe the scale area on the scale disk through the observation window on the window disk. When it rotates to the alignment position of the scale disk and the window disk, the locking bead will be clamped in the locking groove under the action of the locking spring, causing a sense of jerk during the rotation process of the user, facilitating the user to quickly adjust the position of the scale disk, facilitating the user to quickly adjust the display date of the perpetual calendar, and improving the user experience.

[0009] Optionally, a driving member for driving the rotation of the scale disk is further provided on the base. The driving member includes a first bevel gear, a second bevel gear and a rotating rod. The first bevel gear is arranged on the scale disk, the second bevel gear is rotatably connected to the base, and the rotating rod is used to drive the second bevel gear to rotate.

[0010] By adopting the above technical solution, since the perpetual calendar has a long service life and the scale disk needs to be directly touched every time it rotates, the characters on the scale area are easily worn seriously; the driving member reduces the direct contact between the user and the scale disk. When the user needs to adjust the scale disk, the user rotates the rotating rod, the rotating rod drives the second bevel gear to rotate, the second bevel gear drives the first bevel gear to rotate, and the first bevel gear drives the scale disk to rotate relative to the window disk.

[0011] Optionally, the driving member further includes a rotating ring. The rotating ring is rotatably connected to the base. The rotating rod is slidably connected to the rotating ring along the axial direction of the rotating ring, and one end of the rotating rod is used for inserting into the second bevel gear.

[0012] By adopting the above technical solution, since the time interval for adjusting the perpetual calendar is relatively long, usually adjusted once a month, and it is placed on the desktop as a desktop ornament for more time, there will be a situation where the user accidentally touches the rotating rod during the desktop cleaning process, resulting in a change in the display date of the perpetual calendar; after the user adjusts the perpetual calendar, the user can move the rotating rod away from the second bevel gear, so that the rotating rod disengages from the second bevel gear, reducing the accidental touch of the rotating rod by the user when the perpetual calendar does not need to be adjusted.

[0013] Optionally, the driving member further includes a rubber ring. Two annular grooves are formed in the rotating rod along the length direction of the rotating rod. The rubber ring is arranged on the base and is used for cooperating with the annular grooves.

[0014] By adopting the above technical solution, the rubber ring is used for cooperating with the two annular grooves on the rotating rod. The rotating rod has two working states. One state is that the rotating rod is inserted into the second bevel gear, and the other state is that the rotating rod keeps away from the second bevel gear. The rubber ring is used to ensure that the user can identify the positional relationship between the rotating rod and the second bevel gear.

[0015] Optionally, a rotating block is provided at one end of the rotating rod away from the first crown gear, and anti-slip patterns are provided on the rotating block.

[0016] By adopting the above technical solution, when the user rotates the rotating rod, the rotating block can be held, and the anti-slip patterns on the rotating block facilitate the user's grip.

[0017] Optionally, an anti-slip flannelette for increasing the friction with the dial is provided on the base.

[0018] By adopting the above technical solution, the anti-slip flannelette can increase the friction when the dial rotates, reduce the possibility of the dial rotating by itself, and reduce the noise generated by the friction between the rotating disc and the base during the rotation process.

[0019] Optionally, a clamping block is provided on the window disc, and the clamping block is used for clamping and cooperating with the base.

[0020] By adopting the above technical solution, the window disc is installed on the base through the clamping block, and the structure is simple, which is convenient for installation during the production of the perpetual calendar.

[0021] Optionally, the scale area includes a year area circumferentially arranged on the dial and a first week area circumferentially arranged on the dial, the observation window includes a year window opened on the window disc, a month comparison area is arranged on the window disc on one side of the year window, a first week window is also opened on the window disc, and a date comparison area is also arranged on the window disc on one side of the first week window.

[0022] By adopting the above technical solution, when the user rotates the dial, the year area on the dial can be observed through the year window, so as to rotate the year area on the dial to a position corresponding to the month comparison area according to the needs. When the year area on the dial rotates to the required position, the year area cooperates with the month comparison area, and the first week area corresponding to the date comparison area can be observed through the first week window, so as to observe the week information corresponding to different dates in different years and different months.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The locking member is used for positioning the dial, which is convenient for the user to adjust the date displayed by the perpetual calendar;

[0025] 2. The driving member is used for rotating the dial, reducing the user's direct contact with the dial; BRIEF DESCRIPTION OF THE DRAWINGS
