Description

Technical Field

[0001] This utility model relates to the field of testing technology, and in particular to a torque testing platform. Background Technology

[0002] Insulin pens, as a prominent representative of modern medical technology, have become an indispensable part of the daily treatment of diabetes patients worldwide. Their convenient design, accurate dosage, and ease of use greatly improve the convenience and efficiency of patient self-management. However, the performance and quality of insulin pens are directly related to the patient's treatment outcome and safety; therefore, implementing strict quality control standards is crucial.

[0003] Torque plays a crucial role in the manufacturing and use of insulin pens. The rotating components of an insulin pen, such as the cap and dosage adjustment knob, all need to possess certain torque characteristics. This characteristic ensures that they can stably and accurately adjust the insulin dosage, while also resisting external forces during daily use to prevent accidental detachment or damage.

[0004] Insufficient torque in an insulin pen can lead to decreased accuracy in dosage adjustment, thus affecting the patient's blood sugar control. More seriously, insufficient torque may cause parts to loosen or even detach during use, which not only reduces the patient's experience but may also pose a potential threat to their safety. Conversely, excessive torque may cause excessive wear or damage to parts, similarly affecting the proper use of the insulin pen and the accuracy of dosage adjustment.

[0005] When performing torque testing on insulin pens, the stability of the pen casing assembly during rotation is crucial. This stability directly affects the accuracy and reliability of the torque test.

[0006] Therefore, this application develops a torque testing platform to solve the problems existing in the prior art. Utility Model Content

[0007] The purpose of this invention is to provide a torque testing platform to solve the problems existing in insulin pens.

[0008] The technical solution of this utility model is: a torque detection and testing platform, comprising:

[0009] A clamping device includes a support base, an adjusting block, and a pair of clamping assemblies. The adjusting block is fixed below the support base and is symmetrical about the center of the support base. The pair of clamping assemblies are respectively disposed on both sides of the support base along its length and penetrate through the side plate of the support base and the side wall of the adjusting block to the internal space of the adjusting block, clamping the top two sides of the pen shell assembly. The bottom surface of the adjusting block has a circular hole for the pen shell assembly to pass through.

[0010] A connector is located inside the adjusting block. The connector includes a fixing block and a plug post concentric with the circular hole. The fixing block is fixed to the bottom of the support base. The plug post is fixed to the bottom of the fixing block and extends downward along the axial direction of the circular hole, and is connected to a torsion spring in the pen shell assembly.

[0011] A fixed limiting device is located below the clamping device. The fixed limiting device includes a fixed base and a limiting block. The fixed base is connected to the torque testing machine. The limiting block is fixed above the fixed base. The top of the limiting block has a slot that matches the bottom of the pen shell assembly. When the torque testing machine drives the fixed limiting device to rotate, the pen shell assembly rotates together with the fixed limiting device.

[0012] Preferably, the clamping assembly includes a clamping rod and a knob. The knob is located on the side of the side plate away from the adjusting block. The clamping rod is fixed to the knob. The side wall of the adjusting block is provided with an adjusting hole. The clamping rod is screwed onto the side plate and mounted on the adjusting hole. Two stops are provided on the end of the clamping rod away from the knob. The two stops are located on both sides of the side wall.

[0013] Preferably, the diameter of the stop block is larger than the diameter of the clamping rod, and the distance between two adjacent sides of the two stops is greater than the thickness of the side plate.

[0014] Preferably, the outer surface of the plug post is provided with a fixing rod for the torsion spring connection of the pen shell assembly.

[0015] Preferably, the slot includes a first limiting hole and a second limiting hole arranged sequentially along its own axial direction. Both the first limiting hole and the second limiting hole are provided with at least one protrusion in the radial direction. Correspondingly, the outer surface of the pen shell assembly is provided with at least one first anti-rotation block and a second anti-rotation block in the axial direction. The first anti-rotation block and the second anti-rotation block correspond to the protrusions of the first limiting hole and the second limiting hole, respectively.

[0016] Preferably, a pen cap is mounted on the top of the pen shell assembly. When the pen shell assembly rotates with the torque testing machine, a pair of clamping assemblies clamp the pen cap on both sides, causing the pen shell assembly to rotate relative to the pen cap.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] (1) By precisely controlling the extension length of the clamping rod, and using the first limiting hole, the second limiting hole and their corresponding protrusions and the first anti-rotation block and the second anti-rotation block, it is ensured that the pen shell assembly rotates relative to the pen cap during rotation, and the pen shell assembly will not produce additional shaking or offset, which would lead to inaccurate torque detection.

[0019] (2) By adjusting the spacing between the baffles to adapt to pen shell components of different sizes and shapes, the flexibility of the clamping components is improved, enabling the testing platform to be widely used for torque testing of various pen shell components, thus improving the versatility of the equipment.

[0029] The present invention will be further described in detail below with reference to specific embodiments:

[0030] like Figures 1-5 As shown, a torque testing platform includes a clamping device 1, a connector 2, and a fixing and limiting device 3. The clamping device 1 includes a support base 11, an adjusting block 12, and a pair of clamping assemblies 13. The connector 2 includes a fixing block 21 and a connector 22. The fixing block 21 is fixed to the bottom of the support base 11, and the connector 22 is fixed to the bottom of the fixing block 21. The fixing and limiting device 3 includes a fixing base 31 and a limiting block 32. The adjusting block 12 is located below the support base 11 and is symmetrical to the support base 11. A circular hole 122 is opened on the bottom surface of the adjusting block 12 for the pen shell assembly 4 to pass through. The top of the pen shell assembly 4 is provided with a pen cap 41 and a torsion spring is also provided inside. The top of the pen shell assembly 4 is located in the internal space of the adjusting block 12. The pair of clamping assemblies 13 pass through the side plate 1 of the support base 11. The sidewalls 121 of the 11 and the adjusting block 12 clamp the pen cap 41 on both sides to fix the pen cap 41. At this time, the insertion post 22 is inserted into the torsion spring. Because the outer side of the insertion post 22 is provided with a fixing rod 221, one end of the torsion spring is hung on the fixing rod 221. In addition, the lower end of the pen shell assembly 4 is inserted into the slot 33 at the top of the limiting block 32. The limiting block 32 is fixed above the fixing seat 31. The fixing seat 31 is connected to the torque testing machine. When the torque testing machine is started, it drives the fixing seat 31 and the limiting block 32 to rotate together. Because the pen shell assembly 4 is inserted into the slot 33, the pen shell assembly 4 rotates together with the limiting block 32. A pair of clamping assemblies 13 clamp and fix the pen cap 41. Therefore, the pen shell assembly 4 rotates relative to the pen cap 41 with the torsion spring, thereby completing the torque test of the pen shell assembly 4.

[0031] In this embodiment, as Figures 2-4 As shown, the clamping assembly 13 includes a clamping rod 131 and a knob 132. The knob 132 is located on the side of the side plate 111 away from the adjusting block 12. The clamping rod 131 is fixed to the knob 132. The side wall 121 of the adjusting block 12 is provided with an adjusting hole 123. The clamping rod 131 is screwed onto the side plate 111 and mounted on the adjusting hole 123. Two stops 23 are provided on the end of the clamping rod 131 away from the knob 132. The two stops 23 are located on both sides of the side wall 121. The clamping rod 131 is rotatably connected to the side plate 111. When the clamping rod 131 is adjusted... When the joint hole 123 moves in the direction, it will clamp the pen cap 41. The clamping rod 131 is mounted on the adjustment hole 123, which provides support for the clamping rod 131 and allows the clamping rod 131 to move along its own axis without error, which would prevent the pen shell assembly 4 from being unable to be clamped. The diameters of the two baffles are larger than the diameter of the clamping rod 131. When the clamping rod 131 is mounted on the adjustment hole 123, the two baffles are located on both sides of the side wall 121, thereby limiting the range of movement of the clamping rod 131 and preventing the clamping rod 131 from falling off during movement.

[0032] Furthermore, the distance between the two adjacent sides of the two baffles is greater than the thickness of the sidewall 121. The extension length of the clamping rod 131 can be adjusted by setting the distance between the two baffles. Precise control of the extension length of the clamping rod 131 helps to improve the overall accuracy of the equipment. By adjusting the baffle spacing, pen shell assemblies 4 of different sizes and shapes can be adapted. In addition, the baffles not only play a limiting role, but also provide additional structural support. When the clamping rod 131 is subjected to a large external force, the baffles can prevent it from excessively elongating or deforming, thereby enhancing the stability of the entire structure.

[0033] In order to perform torque testing, such as Figures 5-7 As shown, the pen shell assembly 4 can rotate stably without detaching from the limiting block 32. The slot 33 includes a first limiting hole 331 and a second limiting hole 332, and both the first limiting hole 331 and the second limiting hole 332 are provided with a protrusion 333 in the radial direction. Correspondingly, a first anti-rotation block 42 and a second anti-rotation block 43 are provided in the axial direction on the outer side of the pen shell assembly 4. The first anti-rotation block 42 and the second anti-rotation block 43 match the protrusion 333, effectively preventing the pen shell assembly 4 from detaching from the limiting block 32 during rotation. This ensures that the pen shell assembly 4 will not generate additional shaking or displacement during rotation, improves the accuracy and precision of the test, and makes the test results more reliable.
