Example one

As shown in fig. 1, the present embodiment provides a date indicating device, which includes a chassis 1, an indicating member, and a plurality of protrusions 3, wherein the chassis 1 can be mounted on a foreign object, the plurality of protrusions 3 are arranged on the front surface of the chassis 1 at intervals, and the protrusions 3 are used as scales for indicating dates; the indicator can point at the projection 3 corresponding to the preset date and is connected to the chassis 1 to indicate the preset date. The chassis 1 in this embodiment can be mounted to any foreign object for indicating a start date or an expiration date. For example, after the safety tool is tested to be qualified, the date indicating device is used for indicating the safety expiration date, the chassis 1 is arranged on the surface of the safety tool, whether the safety tool is expired or is close to the expiration date can be judged by observing the indicated date, and a worker is reminded to perform the test again in time.

According to the date indicating device provided by the embodiment, the bulge 3 is used for representing the date as the scale, the bulge 3 is not easy to blur under the condition of being exposed to the sun and rain, the definition can be ensured, the indicating piece is movably connected to the chassis 1, and the bulge 3 corresponding to the preset date can be selectively directed and connected to the chassis 1, so that the indication of the preset date is realized. The date indicating device that this embodiment provided can guarantee the clear degree of distinguishing of instruction date for a long time, and the staff of being convenient for judges whether experimental overdue to play the effect of guarantee personal safety.

Optionally, the protrusion 3 is integrally formed with the chassis 1. The connection between the two is firmer, and the two are prevented from being separated when being acted by external force and losing the function of representing time. Of course, the protrusion 3 may be connected to the chassis 1 by other fastening means, for example, by strong glue, by fastening with a fastener, etc.

Specifically, the plurality of protrusions 3 are distributed in three circles with different diameters, the protrusions 3 in the three circles respectively represent the year, the month and the day of the date, the plurality of protrusions 3 in each circle are uniformly distributed around the circumference of the central shaft of the chassis 1, the indicating member comprises three pointers 21, and each pointer 21 correspondingly points to the protrusions 3 in one circle. The preset date can be read by the year, month and day corresponding to the three projections 3 pointed to by the three pointers 21. If part of the projections 3 falls, since the projections 3 in each turn are circumferentially arranged evenly, the date indicated by the falling part can be deduced by the presence of the projections 3, thereby further prolonging the service life of the date indicating device.

More specifically, the three circles of protrusions 3 are a first circle of protrusions 3, a second circle of protrusions 3 and a third circle of protrusions, the first circle of protrusions includes twelve protrusions 3, the protrusions 3 in the first circle of protrusions are used for indicating the year of the date, the second circle of protrusions includes twelve protrusions 3, the protrusions 3 in the second circle of protrusions are used for indicating the month of the date, the third circle of protrusions includes thirty-one protrusions 3, and the protrusions 3 in the third circle of protrusions are used for indicating the day of the date. As shown in fig. 1, a value is marked at each protrusion 3 to make the date read more convenient, and the value in this embodiment is also the protrusion 3 higher than the surface of the chassis 1 to prevent the value from being blurred. If no value is present, a mark is made at the start of the same circle, for example, the projection 3 representing the start scale may be set longer, and the indicated date may also be read by counting the number of projections spaced from the start scale. The third circle of protrusions comprises thirty-one protrusions 3, so that the date of any month can be indicated, the number of the protrusions 3 in the first circle of protrusions is twelve, so that the space occupied by the protrusions 3 in the first circle is not too large, the interval between every two adjacent protrusions 3 is appropriate, and the indication time is prolonged as much as possible. Of course, the protrusions 3 in the first circle of protrusions can be arranged in other numbers, and can be arranged according to the actual application. As shown in fig. 1, the starting scale in the first circle of protrusions is written with a value of 20, which means that the first circle of protrusions increases in the direction of 2020 in the direction of the pointer, and the date shown in fig. 1 is 2023, 2, month and 14, which means that the safety expiration date of the safety tool equipped with the device is 2023, 2, month and 14, before which a test is performed again to determine whether the safety tool meets the requirements of safe use.

Optionally, the radii of the first circle of bulges, the second circle of bulges and the third circle of bulges are increased in sequence. Because the number of the bulges 3 in the third circle of bulges is the largest, the bulges 3 are arranged at the outermost circle, so that the distance between the bulges 3 is more suitable. The first circle of bulges is arranged on the innermost circle, and when the date is read, the year, the month and the day are sequentially read from the innermost circle outwards, so that the indicated date is directly obtained, and the readability is improved.

Specifically, the tail parts of the three pointers 21 are all rotatably connected to the center of the front surface of the chassis 1, and the head parts of the three pointers point to the bulges 3 of the first circle of bulges, the second circle of bulges and the third circle of bulges respectively. The pointer 21 is rotatably connected to the chassis 1, and when the date is indicated, the head of the pointer 21 can be adjusted by shifting, so that the adjustment is more convenient.

More specifically, a clamping protrusion 4 is arranged at the center of the chassis 1, and the clamping protrusion 4 penetrates through the tail parts of the three pointers 21. In this embodiment, protruding 4 and chassis 1 integrated into one piece of card, the protruding 4 one end that deviates from chassis 1 of card has the dop, and the dop is restricted the afterbody of three pointer 21 on protruding 4 of card, prevents that pointer 21 from deviating from, links together pointer 21 and chassis 1, and convenient transport storage still makes pointer 21 be difficult for losing.

The date indicating device provided by the embodiment further comprises a fixing piece 5, and the fixing piece 5 is used for fixing the indicating piece on the chassis 1. As shown in fig. 2, a groove 51 is formed at the bottom of the fixing member 5, the bottom end of the fixing member 5 is fixed to the chassis 1, and the pointer 21 is fixed in the groove 51 to prevent the pointer 21 from moving. In this embodiment, three fixing members 5 are provided for fixing three pointers 21, respectively. The fixing piece 5 is made of plastic soft glue, and the fixing piece 5 is connected to the chassis 1 through waterproof glue.

Optionally, the back surface of the chassis 1 is provided with an adhesive layer, and the adhesive layer can be adhered to an external object. In order to prevent the chassis 1 from falling off due to rain, the adhesive layer is made of waterproof colloid.

Example two

Fig. 3 and 4 show a second embodiment, wherein the same or corresponding parts as those of the first embodiment are provided with the same reference numerals as those of the first embodiment. For the sake of simplicity, only the difference between the second embodiment and the first embodiment is described, the difference is that the chassis 1 has a plurality of annular steps 11 descending from the center to the edge in sequence, the first ring of protrusions, the second ring of protrusions, and the third ring of protrusions are respectively located on the top surfaces of three different annular steps 11, a slot 111 is formed on the side surface of each annular step 11, the head of the pointer 21 is provided with a hook 22, the hook 22 is located in the slot 111, and the pointer 21 can drive the hook 22 to slide in the slot 111 when rotating. Because the hook 22 is slidably disposed in the slot 111, the slot 111 limits the head of the pointer 21 from moving away from the chassis 1, so that the connection between the pointer 21 and the chassis 1 is more stable.
