Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a device for detecting the service life of a fountain pen. Background Art

[0002] Water pen refers to a pen that can be used for both calligraphy and painting. Because of its convenience, cleanliness and fluent writing, after more than ten years of development, it has become popular in large and small government agencies, companies, enterprises and colleges and universities.

[0003] The main solvent of a fountain pen is water. In order to reduce the volatilization of ink, a fountain pen can use a sharp pen tip, which is the distinguishing feature of a fountain pen from other pens (ballpoint pens or gel pens). Moreover, the ink of a fountain pen is mostly not waterproof and cannot withstand sunlight, making it unsuitable for long-term storage. Therefore, the structure of the fountain pen needs to be reasonably designed to be more suitable for use. Among them, the use time of the fountain pen and the fact that writing and drawing notes are not damaged due to interference require careful consideration. Therefore, the detection device of the fountain pen needs to be designed specifically to carry out the detection work of the fountain pen.

[0004] Chinese Patent Authorization Announcement No.: CN213543987U, Authorization Announcement Date: June 25, 2021, discloses an online detection device for the service life of a fountain pen, including a detection platform, the bottom surface of the detection platform is provided with a non-slip base, the top surface of the detection platform is provided with a cardboard, the top surface of the detection platform is provided with a rotating device, the rotating device is located on both sides of the cardboard, the top surface of the rotating device is provided with a fixing device, a water-based pen is provided between the rotating device and the fixing device, the top surface of the detection platform is provided with symmetrical support columns, the support columns are located on both sides of the rotating device, and the top surface of the support columns is provided with The support plate, the top surface of the support plate is provided with an electric motor, and the bottom end of the electric motor is provided with a rotating rod. The shortcoming of this technical solution is that when performing the detection of the water pen, the tip of the water pen is first placed downward, and then placed in the mounting hole opened in the mounting plate, and the pen tip is made to contact the cardboard placed on the detection table. The mounting hole here is installed with a rubber sleeve, so the lower end of the water pen is in a state of being covered by the rubber sleeve, and the top end of the water pen is under the limiting effect of the fixed groove on the fixed plate. Finally, the electric motor drives the water pen to draw on the cardboard for detection. However, the top and bottom ends of the water pen are both provided with a tightly connected structure. In other words, the lower end of the water pen is in the rubber sleeve, and the top end is limited by the fixed groove, and it can still rotate under force. For the water pen with a pointed pen head, not only is the detection work imperfect, there is a difference in the direction of the tip, and even the pen head may be broken under force during drawing.

[0005] In summary, a structure can be provided to allow the fountain pen to be stably limited for detection work. Utility Model Content

Here, the jack limiting block 18 and the detection platform 1 are selectively plugged in, so that the cardboard 15 is limited by the jack limiting block 18 and the cardboard edge groove 17, so as to avoid being separated from the cardboard limiting groove 14.

[0027] Then, the limiting plate 2 6 is controlled to move upward under the limiting effect of the connecting rod 21, and then the pen 12 can be placed between the limiting plate 2 6 and the limiting plate 1 5, so that the bottom end of the pen 12 passes through the limit hole 1 on the limiting plate 1 5 and the connection with the cardboard 15, and then the lower end of the pen 12 is sleeved in the elastic ring 20 in the limiting hole 1 and is limited by the elastic ring 20.

In this way, the locking cap 26 and the locking ring 25 are threadedly connected through the second thread and the first thread, so that the top of the fountain pen 12 can be stably limited. In this way, the two ends of the fountain pen 12 are limited, which can prevent the fountain pen 12 from rotating at will. The material of the elastic ring 20 and the locking ring 25 here can be selected from rubber with elastic effect, which is convenient for controlled squeezing of the fountain pen 12, thereby applying stable limitation. The limiting ring 23 at the connecting hole may also be provided with a screw hole, and the limiting plate 26 may be provided with a screw groove. Then, by controlling the screw, the connecting rod 21 and the limiting plate 26 are connected in coordination with the screw groove and the screw hole. The bottom end of the compression spring 22 mounted on the connecting rod 21 is connected to the top end of the limiting plate 1 5, and the top end is connected to the bottom end of the limiting plate 26. In this way, the movement of the limiting plate 26 is stably carried out under the elastic effect of the compression spring 22.

[0028] Then, through the control of the switch assembly 11, the motor shaft 9 on the motor 8 drives the limit plate 2 6 to rotate, and the limit plate 1 5 connected to the limit plate 2 6 is also driven to rotate, so that the pen 12 under the limit of the limit plate 1 5 and the limit plate 2 6 can be driven to rotate, and the bottom of the pen 12 can draw circles on the paperboard 15, and the information of the motor 8 starting to work is transmitted to the single-chip microcomputer, and then transmitted to the display 10 after processing by the single-chip microcomputer, and the display 10 displays the working time of the motor 8, that is, the circle drawing time of the pen 12. When the pen 12 draws circles on the paperboard 15, due to the thickness of the paperboard 15, the limit of the paperboard limit slot 14, the jack limit block 18 and the paperboard edge slot 17 reduces the probability of the paperboard 15 being wrinkled or scratched. Then until the ink of the fountain pen 12 is used up, the time displayed on the display 10 at this time is the usable time of the fountain pen 12, that is, the service life of the fountain pen 12, and the limiting components at both ends of the fountain pen 12 here have achieved the purpose of allowing the fountain pen 12 to perform detection work in a stable limiting state. In particular, a plurality of limiting jacks 1 can be set on the limiting plate 1 5 in the detection device, and a plurality of limiting jacks 2 are correspondingly set on the limiting plate 2 6, so that a plurality of fountain pens 12 can be installed on the detection device and perform detection work at the same time. Of course, the limiting jacks 1 can be symmetrically distributed with the center of the limiting plate 1 5 as the base point, and the limiting jacks 2 correspond to the limiting jacks one by one, so that a plurality of fountain pens 12 can draw circles at the same time, so that it can be seen whether the time when the ink of each fountain pen 12 is used up is close, and the judgment of the service life of the fountain pen 12 is more accurate. The limiting hole 1 is not provided at the center of the limiting plate 15 as much as possible, that is, the fountain pen 12 is not installed at the center of the limiting plate 15 as much as possible, because the center of the limiting plate 15 corresponds to the center of the paperboard 15 above and below. If the fountain pen 12 is installed here, the bottom of the fountain pen 12 can only rotate in place, which brings inaccurate data for the service life detection of the fountain pen. The two ends of the fountain pen 12 limit the bottom of the fountain pen 12, that is, the pen tip of the fountain pen 12, to have a certain direction. The sharp pen tip has a certain direction when the fountain pen 12 rotates, thereby reducing the probability of the pen tip being broken when the fountain pen 12 draws circles.

[0029] Moreover, the top of the support block 2 is connected to the bottom of the testing platform 1, and a non-slip base 27 is installed at the bottom, which not only allows the support block 2 to support the testing platform 1, but also allows the non-slip base 27 to prevent the testing platform 1 from sliding, thereby allowing the testing work of the service life of the fountain pen to be carried out stably. Of course, the material of this non-slip base 27 can also be rubber.
