Description

Technical Field

[0001] This utility model relates to the field of ballpoint pen writing detection technology, specifically to a ballpoint pen writing detection mechanism. Background Technology

[0002] Ballpoint pens are one of the most widely used types of pens in daily life, and the writing capacity of the pen refill is one of the most important factors that determines whether consumers will buy a ballpoint pen. The pen tip and the amount of ink in a ballpoint pen refill both determine the lifespan of the pen refill.

[0003] In response, Chinese patent application number CN202422297816.7 discloses a ballpoint pen writing testing mechanism, including a testing platform. A mounting frame is fixedly installed on one side of the top of the testing platform, and a cylinder is fixedly installed on one side of the mounting frame. A first clamping frame is located on the other side of the testing platform, and the output shaft of the cylinder is fixedly connected to the outer surface of the first clamping frame. A second clamping frame is provided on one side of the first clamping frame on the testing platform. Both the first and second clamping frames have clamping grooves on their outer surfaces, and clamping components are disposed inside the clamping grooves. This utility model can clamp and fix multiple ballpoint pens by setting the clamping components. During testing, multiple ballpoint pens can be tested simultaneously. Furthermore, the cylinder-driven method during testing moves the ballpoint pens, allowing adjustment of the pen's writing speed and improving the testing effect.

[0004] The device uses two sets of clamps to fix the ballpoint pen and pull the paper from below, causing the paper to move relative to the ballpoint pen for testing. However, in actual testing, the ballpoint pen writes on the paper in a fixed direction, which causes the ball on the pen tip to roll in a fixed direction. This is very limiting, as the ball cannot roll in all directions on the pen tip, making the test results unrepresentative.

[0005] Therefore, in order to solve the above problems, a ballpoint pen writing testing mechanism is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a ballpoint pen writing detection mechanism to solve the problem mentioned in the background art that the prior art device can fix the ballpoint pen by setting two sets of clamps and pull the paper from the bottom so that the paper moves relative to the ballpoint pen for detection. However, in actual detection, the ballpoint pen writes on the paper in a fixed direction, which causes the ball on the pen tip to roll in a fixed direction. This has great limitations, and the ball cannot roll in all directions on the pen tip, making the detection results unrepresentative.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a ballpoint pen writing detection mechanism, comprising: a base, a controller mounted on the front end of the top surface of the base, and a writing board adhered to the middle of the top surface of the controller;

[0008] A detection structure is mounted on the base. The detection structure includes a fixed frame, which is fixedly installed in the center of the top surface of the controller. A movable groove is formed on the surface of the fixed frame. A movable block is slidably installed inside the movable groove. A pen slot is formed on the top surface of the movable block. An abutment block is fixedly connected to the left end of the movable block. A cam is movably installed inside the left end of the fixed frame via a bearing. A pen to be tested is inserted into the inner side of the pen slot. A spring is fixedly connected to the right end of the movable block. A hand-cranked threaded rod is movably installed on the front of the movable block via a thread. A rotating block is rotatably connected to the rear end of the hand-cranked threaded rod. A rubber pad is adhered to the back of the rotating block. A motor is fixedly installed on the top surface of the left end of the fixed frame.

[0009] Preferably, the top surface of the writing board is covered with paper, and the bottom end of the pen to be tested is attached to the top surface of the paper.

[0010] Preferably, the length of the movable block is less than the length of the movable groove, the abutment block is adapted to the cam, and the output end of the motor is fixedly connected to the cam.

[0011] Preferably, one end of the spring is fixedly connected to the inner wall of the movable groove.

[0012] Preferably, the hand-threaded rod is located at the front of the pen to be tested, the rear end of the hand-threaded rod is located inside the pen groove, and the back of the rubber pad abuts against the surface of the pen to be tested.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the movable block set in this utility model can reciprocate in the left and right direction on the fixed frame under the cooperation of the cam and the spring, so that when the paper is pulled and moved, the pen under test can draw a zigzag mark on the paper, which can more comprehensively test the smoothness of the ball bearing and enhance the practicality of the device.

[0014] This invention features a detection structure. Paper is laid on the top surface of a writing board, and the pen to be tested is inserted downwards into the pen slot, ensuring the bottom of the pen is in contact with the top surface of the paper. Rotating the hand-threaded rod, which is threadedly connected to a movable block, causes the rotating block to move closer to the pen, and the rubber pad abuts against the pen, thus securing it. Each pen corresponds to a specific hand-threaded rod, making assembly and disassembly convenient. The paper moves on the top surface of the writing board under the traction mechanism. As the paper moves relative to the pen, the ball bearing on the pen rolls on the paper, allowing lines to be drawn. Starting the motor drives... When the cam rotates, its convex end contacts the abutment block, pushing the abutment block and causing the movable block to slide within the movable groove. As the movable block moves, it compresses the spring. When the motor's input separates from the abutment block, the movable block loses its push, the spring returns to its original position, and the movable block resets. The movable block then drives the pen under test to reciprocate left and right, while the paper moves beneath the pen. The pen under test can then draw zigzag lines on the paper. When the pen under test is drawing lines, the ball bearing deflects horizontally at the bottom of the pen, allowing for a more comprehensive test of the ball bearing's smoothness and enhancing the device's practicality.

[0022] The base 1, controller 11, writing board 12, pen to be tested 27 and motor 212 used in this application are products that can be purchased directly on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0023] A ballpoint pen writing detection mechanism includes: a base 1, a controller 11 installed at the front end of the top surface of the base 1, and a writing board 12 attached to the middle of the top surface of the controller 11.

[0024] A detection structure 2 is mounted on the base 1. The detection structure 2 includes a fixing frame 21, which is fixedly mounted on the center of the top surface of the controller 11. A movable groove 22 is formed on the surface of the fixing frame 21. A movable block 23 is slidably mounted inside the movable groove 22. A pen slot 24 is formed on the top surface of the movable block 23. An abutment block 25 is fixedly connected to the left end of the movable block 23. A cam 26 is movably mounted inside the left end of the fixing frame 21 via a bearing. A pen to be tested 27 is inserted into the inner side of the pen slot 24. A spring 28 is fixedly connected to the right end of the movable block 23. A hand-cranked threaded rod 29 is movably mounted on the front via a thread. A rotating block 210 is rotatably connected to the rear end of the hand-cranked threaded rod 29. A rubber pad 211 is adhered to the back of the rotating block 210. A motor 212 is fixedly mounted on the top left end of the fixing frame 21. The movable block 23 can reciprocate left and right on the fixing frame 21 under the action of the cam 26 and the spring 28. This allows the pen under test 27 to draw zigzag marks on the paper when it is being pulled and moved, enabling a more comprehensive test of the smoothness of the ball bearing and enhancing the practicality of the device.

[0025] Furthermore, paper is laid on the top surface of the writing board 12, and the bottom end of the pen to be tested 27 is attached to the top surface of the paper, and the paper can move under the pen to be tested 27.

[0026] Furthermore, the length of the movable block 23 is less than the length of the movable groove 22, the abutment block 25 is adapted to the cam 26, the output end of the motor 212 is fixedly connected to the cam 26, the movable block 23 can move inside the movable groove 22, the motor 212 provides power for the rotation of the cam 26, and the rotation of the cam 26 can push the abutment block 25.

[0027] Furthermore, one end of the spring 28 is fixedly connected to the inner wall of the movable groove 22, and the spring 28 provides power for the movable block 23 to reset inside the movable groove 22.

[0028] Furthermore, the hand-threaded rod 29 is located on the front side of the pen to be tested 27, and the rear end of the hand-threaded rod 29 is located inside the pen groove 24. The back of the rubber pad 211 abuts against the surface of the pen to be tested 27. The rubber pad 211, together with the hand-threaded rod 29, provides a limit for fixing the pen to be tested 27 inside the movable block 23.

[0029] Working principle: Before testing, paper is laid on the top surface of the writing board 12. The pen to be tested 27 is inserted downward into the pen slot 24 so that the bottom end of the pen to be tested 27 is in contact with the top surface of the paper. The hand-turned threaded rod 29 is rotated. The hand-turned threaded rod 29 is threadedly connected to the movable block 23. When the hand-turned threaded rod 29 is rotated, it drives the rotating block 210 to approach the pen to be tested 27. The rubber pad 211 then abuts against the pen to be tested 27, which can fix the pen to be tested 27. The pen to be tested 27 and the hand-turned threaded rod 29 correspond one-to-one, making disassembly and assembly convenient.

[0030] During testing, the paper moves on the top surface of the writing board 12 under the drive of the traction mechanism. The paper moves relative to the pen to be tested 27, and the ball on the pen to be tested 27 rolls on the paper, so that a line can be drawn on the paper.

[0031] When the motor 212 is started, the cam 26 is rotated. When the cam 26 rotates, the convex end contacts the abutment block 25, pushing the abutment block 25 and causing the movable block 23 to slide in the movable groove 22. When the movable block 23 moves, it will compress the spring 28. When the inlet of the motor 212 separates from the abutment block 25, the movable block 23 loses its push, the spring 28 returns to its original state, and the movable block 23 returns to its original state. The movable block 23 then drives the pen under test 27 to move back and forth in the left and right direction, and the paper moves under the pen under test 27. The pen under test 27 can then draw a zigzag line on the paper. When the pen under test 27 draws a line, the ball will deflect horizontally at the bottom of the pen under test 27, which can more comprehensively test the smoothness of the ball and enhance the practicality of the device.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way.
