Description

Technical Field

[0001] This utility model relates to the field of circle drawing instruments, specifically a writing circle drawing instrument with an adjustment and calibration mechanism. Background Technology

[0002] As an important instrument for testing the writing ability of stationery pens, the writing test circler is used to test the smoothness and wear resistance of pen tips produced by stationery manufacturers. During the test, it is necessary to adjust the pressure between the pen tip and the paper to test the writing smoothness of the pen tip under different pressures, and adjust the angle between the pen tip and the paper to test the durability of the pen tip.

[0003] Existing writing circle markers require multiple pen refills to be filled inside the tube during use, and then the writing position and angle of the refills are controlled by the same bracket. This method can only test the writing of the pen refills under the same pressure, and it is difficult to simulate the different pen grip angles and writing habits of different users in reality. This makes the writing test data of the pen refills relatively singular and unable to comprehensively and accurately reflect the real performance of the pen refills in actual writing scenarios. As a result, the data obtained cannot fully cover various actual writing situations, and therefore it is difficult to provide rich and targeted basis for further optimization and improvement of the pen refills. Optimization and improvement are needed. Utility Model Content

[0004] The purpose of this invention is to provide a writing circle instrument with an adjustment and calibration mechanism to solve the problem mentioned in the background art that it is difficult to perform multi-directional adjustment and calibration of pen refills during factory writing tests, resulting in relatively simple writing test data and difficulty in providing targeted basis for pen refill optimization or improvement.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a writing circle marker with an adjustable calibration mechanism, comprising: a support frame, a feeding frame installed at the rear top of the support frame, a shaking table provided on the inner side of the support frame, a winding frame connected to the rear end of the support frame, and further comprising a calibration adjustment component and a clamping positioning component.

[0006] The calibration adjustment assembly includes a rotating support rod, which is located at the top center of the support frame. An adjustment clamp is provided on the outer side of the rotating support rod, and a fixing frame is provided on the outer side of the adjustment clamp. A clamping block is provided on the inner side of the fixing frame. The calibration adjustment assembly is used to adjust different writing and drawing circle positions. The clamping positioning assembly includes a limiting plate, which is located at one inner end of the fixing frame. A compression pad is provided on the inner side of the limiting plate, and an adjustment plate is connected to one side of the limiting plate. The clamping positioning assembly is used to reinforce the installation position.

[0007] Preferably, a fastening screw is connected to one end of the inner side of the adjusting clip, and a plug groove is provided on the inner side of the adjusting clip.

[0008] Preferably, one end of the adjusting clamp is connected to a positioning mounting plate.

[0009] Preferably, a plug block is provided on the inner side of the plug slot, and the fixing frame is connected to the outer side of the plug block.

[0010] Preferably, guide rods are connected to both ends of the inner side of the limiting plate, and a rotating screw is connected to the inner side of the adjusting plate.

[0011] Preferably, both the upper and lower ends of the clamping block are connected to a beveled joint, and the inner side of the beveled joint is connected to a snap-fit ​​block.

[0012] Preferably, the outer side of the clamping block is connected to an adjusting fastening ring, and two adjusting fastening rings are provided.

[0013] Preferably, the inner side of the clamping block is provided with a pen refill body.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention allows for position adjustment of the pen refill body. The overall rotation angle can be adjusted by rotating the support rod, and the rotation angle can also be adjusted by adjusting the clamp on the outside of the rotating support rod. Furthermore, the outer fixing frame can be replaced according to the required spacing. This allows for adjustment of the force and angle of the pen refill body contacting the paper within a certain range, enabling the equipment to cover various actual writing situations during testing. This provides rich and targeted data for further optimization and improvement of the pen refill body, thereby improving the efficiency of the equipment.

[0016] When positioning the pen refill body, the upper and lower end adjustment and fastening rings are tightened to prevent the pen refill body from shifting. Then, the clamping block is positioned by adjusting the limit plate and adjustment plate, ensuring the stability of the pen refill body during testing and thus improving the accuracy of the equipment's test data.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0024] like Figure 1 - Figure 4 As shown, this application provides a writing circle marker with an adjustment and calibration mechanism, including: a support frame 1, a feeding frame 2 installed at the rear of the top of the support frame 1, a shaking table 3 provided on the inner side of the support frame 1, a winding frame 4 connected to the rear end of the support frame 1, and also including a calibration and adjustment component and a clamping and positioning component.

[0025] The calibration adjustment assembly includes a rotating support rod 5, which is located at the top center of the support frame 1. An adjustment clip 6 is provided on the outside of the rotating support rod 5, and a fixing frame 11 is provided on the outside of the adjustment clip 6. A clamping block 17 is provided on the inside of the fixing frame 11. The calibration adjustment assembly is used to adjust different writing and drawing circle positions.

[0026] Specifically, such as Figure 2 As shown, a fastening screw 7 is connected to one end of the inner side of the adjusting clip 6, and a insertion groove 8 is provided on the inner side of the adjusting clip 6. The fastening screw 7 is used to tighten and position the adjusting clip 6 after it has been rotated to adjust its position.

[0027] Specifically, such as Figure 2 As shown, one end of the adjusting clip 6 is connected to the positioning mounting plate 9. After the plug-in block 10 and the plug-in slot 8 are plugged in, the outer side will be fixedly connected by the positioning mounting plate 9.

[0028] Specifically, such as Figure 2As shown, a plug block 10 is provided on the inner side of the plug slot 8, and a fixing frame 11 is connected to the outer side of the plug block 10. The fixing frame 11 is used to support the fixing mechanism of the pen refill body 21.

[0029] The clamping positioning assembly includes a limiting plate 12, which is located at one end of the inner side of the fixed frame 11. A compression pad 13 is provided on the inner side of the limiting plate 12, and an adjusting plate 15 is connected to one side of the limiting plate 12. The clamping positioning assembly is used to reinforce the installation position.

[0030] Specifically, such as Figure 3 As shown, guide rods 14 are connected to both ends of the inner side of the limiting plate 12, and a rotating screw 16 is connected to the inner side of the adjusting plate 15. The rotation of the rotating screw 16 will drive the adjusting plate 15 to move closer to or away from the limiting plate 12. The rotating screw 16 and the limiting plate 12 are rotatably connected. The movement of the adjusting plate 15 is guided by the guide rods 14 to improve the accuracy of the position movement.

[0031] Specifically, such as Figure 4 As shown, both the upper and lower ends of the clamping block 17 are connected to the oblique connecting blocks 18, and the inner side of the oblique connecting blocks 18 is connected to the snap-fit ​​block 19. The oblique connecting blocks 18 make it easier to adjust the fastening ring 20 onto the clamping block 17. The protrusion of the snap-fit ​​block 19 is snapped onto the outer side of the pen refill body 21 for limiting.

[0032] Specifically, such as Figure 4 As shown, an adjusting fastening ring 20 is connected to the outer side of the clamping block 17, and there are two adjusting fastening rings 20. The upper and lower adjusting fastening rings 20 are rotated and fixed to improve stability.

[0033] Specifically, such as Figure 4 As shown, the inner side of the clamping block 17 is provided with the pen refill body 21, and the outer side of the clamping block 17 is provided with a threaded groove, which facilitates the adjustment and tightening of the fastening ring 20, and can also increase the friction when in contact with the limiting plate 12 and the adjusting plate 15.

[0034] In this embodiment: the position of the pen refill body 21 is adjusted by rotating the support rod 5. The adjustment clamp 6 is rotated and adjusted on the outside of the support rod 5. The outer fixing frame 11 can also be replaced according to the required spacing. This allows the force and angle of the pen refill body 21 contacting the paper to be adjusted within a certain range, so that the device can cover various actual writing situations during testing. When positioning the pen refill body 21, the upper and lower adjusting fastening rings 20 are tightened to prevent the position of the pen refill body 21 from shifting. Then, the clamp 17 is positioned by adjusting the limit plate 12 and the adjusting plate 15 to ensure the stability of the pen refill body 21 during testing.

[0035] The specific solution is as follows: When testing the writing smoothness and lifespan of the pen refill body 21, the pen refill body 21 needs to be positioned first. During positioning, the upper and lower end adjustment and fastening rings 20 are tightened and fixed. The angled connecting block 18 facilitates the insertion of the adjustment and fastening rings 20. The inner side is secured to the outer wall of the pen refill body 21 by the snap-fit ​​block 19 to prevent the position of the pen refill body 21 from shifting. Then, the rotating screw 16 is rotated to move the adjusting plate 15 closer to the limiting plate 12 to position and clamp the clamping block 17. The inner compression pad 13 and the outer thread of the clamping block 17 will increase the stability during clamping and positioning. To ensure that the pen refill body 21 does not shift during detection, the position of the pen refill body 21 is adjusted according to writing needs. The entire pen refill body 21 can be rotated by rotating the support rod 5 to control the angle at which the pen refill body 21 contacts the top of the paper on the shaking table 3. The adjusting clip 6 is rotated and adjusted on the outside of the rotating support rod 5 to further control the detection angle of different pen refill bodies 21. The outer fixing frame 11 can also be replaced according to the required spacing. The insertion block 10 is connected to the insertion slot 8 through a snap-fit ​​connection, making disassembly and replacement more convenient. This setting allows the force and angle of the pen refill body 21 contacting the paper to be adjusted within a certain range, making the detection more comprehensive.
