Description

Technical Field

[0001] This utility model relates to the technical field of ballpoint pen testing, and in particular to a ballpoint pen ball bearing impact resistance testing device. Background Technology

[0002] Ballpoint pens use dry, thick ink, relying on a freely rotating steel ball at the tip to transfer the ink onto paper. They offer advantages such as leak-proof writing, resistance to weather conditions, long writing time, and no need for frequent refills. The ballpoint pen's ink ball is the part that contacts the paper. If dropped tip-down, the ink ball will be damaged, rendering it unusable. Therefore, the ink ball needs to have a certain degree of durability. Testing the ballpoint pen's impact resistance ensures it is within acceptable limits and can be used for a long time. Existing testing devices require recording the pen's writing activity after a natural drop, a manual recording process that is inconvenient.

[0003] Chinese Patent Publication No. CN217981102U, published on December 6, 2022, discloses an impact-resistant testing device for ballpoint pen ink. The device includes a base plate with a support plate connected to it. One side of the support plate has a slot and a stabilizing plate, which is inserted into the support plate via the slot. The stabilizing plate has a movable through hole through which a pen clip is slidably connected. The other side of the support plate has a load-bearing plate with a pen slot on its lower surface and a storage slot on its upper surface. The support plate also has a telescopic mechanism horizontally aligned with the load-bearing plate. A drawback of this invention is that, during free-fall impact testing, manual recording of the writing is required after the impact, which is inconvenient. Utility Model Content

[0004] This invention aims to overcome the shortcomings of existing technologies that require manual recording of writing after impact testing, and provides a ballpoint pen ball impact resistance testing device that can automatically record writing after a ballpoint pen is naturally dropped.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An impact resistance testing device for ballpoint pen balls includes:

[0007] A test fixture, wherein the test fixture is provided with a guide groove;

[0008] The lowering gear is mounted on the side of the test frame and matches the guide slot;

[0009] A lifting assembly, which is mounted on the top of the test frame and matches the drop frame;

[0010] A lateral movement assembly, which is mounted on the test frame and positioned below the drop frame;

[0011] A writing board is mounted on the bottom surface of the test frame, and the writing board corresponds to the drop frame.

[0012] The test device installed on the test rack tests the cylindrical pen. The drop frame on the test rack guides the descent direction along the guide groove. The ballpoint pen is placed on the drop frame, and the pen is released by releasing the drop frame, allowing the cylindrical pen to fall freely. The drop frame descends along the guide groove, ensuring that the cylindrical pen falls vertically, thus testing the impact resistance of the ballpoint pen. After the impact, the horizontal movement component moves the functional drop frame laterally along the guide groove, moving the ballpoint pen to the writing board for writing. The writing status of the cylindrical pen after the impact is recorded in time. After recording the writing status, the horizontal movement component moves the drop frame back to its original position, and then the lifting component raises the drop frame again to prepare for the next impact test. This achieves the purpose of automatically recording the writing status in time after the cylindrical pen falls naturally.

[0013] Preferably, the test frame has an L-shaped cross-section and includes a base plate and a side plate. One end of the base plate is connected to one end of the side plate. The guide groove is placed on the side plate and has an L-shaped cross-section. The guide groove includes a drop groove and a transverse groove. One end of the drop groove is connected to the transverse groove. The drop frame includes a drop plate and a moving block is installed on the drop plate. The drop plate is slidably connected to the side plate through the cooperation of the moving block and the drop groove. The bottom surface of the moving block is provided with a sliding column. The transverse groove is provided with a sliding groove. The sliding column corresponds to the sliding groove. The drop plate is provided with an insertion hole. The test frame has an L-shaped cross-section. The side plate of the test plate frame has a guide groove. The L-shaped guide groove guides the movement direction of the drop frame on the test frame. A ballpoint pen is placed in the insertion hole of the drop plate. The ballpoint pen is not fixed. The drop plate descends along the drop groove through the cooperation of the moving block and the drop groove. The drop frame and the ballpoint pen fall at the same time. The drop frame restricts the ballpoint pen to impact in a vertical state. A sliding column is installed on the moving block of the drop frame. After falling to the bottom, it will insert into the sliding groove and move laterally in the transverse sliding groove. This design can better guide the movement of the ballpoint pen.

[0014] Preferably, a bonding plate is installed on the bottom surface of the drop plate, corresponding to the insertion hole. A pressing plate is provided on the bottom surface of the drop plate, and a sliding block is installed on the pressing plate. A sliding groove is provided on the drop plate. The pressing plate is slidably connected to the drop plate through the cooperation of the sliding block and the sliding groove. A pressing block is installed on the side of the pressing plate facing the bonding plate. An electric push rod is installed on the drop plate, and the top end of the electric push rod is connected to the pressing block. A bonding plate corresponding to the insertion hole is installed below the drop plate, and a pressing plate is installed on the other side of the insertion hole. The pressing plate can move along the sliding groove. The electric push rod pushes the pressing plate to move, causing the pressing block on the pressing plate to press the ballpoint pen, fixing its position. After the ballpoint pen is fixed, it can write normally. This design can clamp the ballpoint pen.

[0015] Preferably, the lifting assembly includes a motor and a winding shaft. A motor mount is installed at the top of the side plate, and the motor is mounted on the motor mount. The winding shaft is mounted on the motor shaft of the motor, and a lifting rope is provided on the winding shaft. One end of the lifting rope is connected to the winding shaft, and a magnet is installed at the other end of the lifting rope. An adsorption plate is installed on the drop plate, and the magnet corresponds to the adsorption plate. The lifting assembly is used to lift the drop frame for easier testing. The magnet on the lifting rope attracts the adsorption plate on the drop plate, connecting it to the drop frame. Then, the motor drives the winding shaft to rotate, raising the drop plate by winding the lifting rope. After raising the drop plate to the top of the drop trough, the lifting rope is wound again to separate the magnet from the adsorption plate. At this point, the drop plate descends for testing. When connection with the drop plate is needed, the lower magnet simply contacts the adsorption plate. This design allows the drop plate to move.

[0016] Preferably, the transverse moving assembly includes a transverse moving plate and a second motor. A second sliding block is installed on the side of the side plate away from the bottom plate. A second sliding groove is provided on the transverse moving plate. The transverse moving plate is slidably connected to the side plate through the cooperation of the second sliding block and the second sliding groove. The second motor is installed on the transverse moving plate. A first gear is installed on the motor shaft of the second motor. A rack is installed on the side plate. The first gear meshes with the rack. A moving groove is installed on the side plate. An insert rod is provided on the transverse moving plate. One end of the insert rod is connected to the transverse moving plate. The other end of the insert rod passes through the moving groove and is placed on the other side of the side plate. Two limiting rods are installed below the lower plate. The limiting rods correspond to the insert rod. The two limit rods installed on the bottom of the falling plate will be inserted into the two sides of the insertion rod of the horizontal plate after falling. The horizontal plate moves along the sliding block two, and the motor two on the horizontal plate rotates. The gear one on the motor two meshes with the rack and pinion to drive the horizontal plate to move. The horizontal plate drives the insertion rod to move in the moving groove, which in turn drives the falling plate to move in the horizontal moving groove, thereby driving the ballpoint pen to write. This design allows the falling plate to move laterally.

[0017] Preferably, the base plate is provided with a sliding groove three, and the writing board is equipped with a sliding block three. The writing board is slidably connected to the base plate through the cooperation of the sliding block three and the sliding groove three. Support columns are installed on both sides of the writing board, and a clamping plate is provided on the support column. One end of the clamping plate is connected to the support column, and the other end of the clamping plate contacts the writing board. The writing board installed on the base plate can move along the sliding groove three, which can change the writing position of the ballpoint pen on the paper and make full use of the paper. At the same time, the paper is fixed on the writing board by the clamping plates on the support columns to prevent the paper from moving. This design can make full use of the paper.

[0018] Preferably, an impact plate is mounted on the base plate, and the impact plate corresponds to the insertion hole. By mounting an impact plate on the base plate corresponding to the insertion hole position, the impact surface can be changed by replacing the impact plate, thereby observing the impact effect of different impact surfaces. This design allows for testing under different impact surfaces.

[0019] The beneficial effects of this utility model are: it can automatically record the writing situation in a timely manner after the ballpoint pen falls naturally, it can better guide the movement of the ballpoint pen, it can clamp the ballpoint pen, it can drive the falling plate to move, it can move the falling plate laterally, it can make full use of the paper, and it can conduct tests under different impact surfaces.

A magnet 35 is installed on the other end of the lifting rope 34. An adsorption plate 36 is installed on the drop plate 21. The magnet 35 corresponds to the adsorption plate 36.

[0037] like Figure 4 , Figure 5 As shown, the transverse assembly 4 includes a transverse plate 41 and a second motor 42. A second sliding block 17 is installed on the side of the side plate 13 away from the bottom plate 12. The transverse plate 41 is provided with a second sliding groove 43. The transverse plate 41 is slidably connected to the side plate 13 through the cooperation of the second sliding block 17 and the second sliding groove 43.
