In actual production, due to the diverse specifications and varying lengths of insulin pen plungers, traditional testing equipment requires frequent mold changes or complex parameter adjustments when dealing with plungers of different specifications. This not only increases the difficulty and time cost of production operations but may also introduce additional measurement errors due to frequent mold changes or parameter adjustments, affecting the accuracy and consistency of the test results. Utility Model Content

[0004] The purpose of this invention is to provide an insulin pen plunger length detection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an insulin pen plunger length detection device, comprising a track base, a first clamping component, and a second clamping base component. Adjustable base components are connected and installed on both the left and right ends of the track base. The first clamping component is installed on top of a set of adjustable base components, and an assembly frame is installed in the middle of the top of the first clamping component. A laser rangefinder is horizontally installed inside the assembly frame. The second clamping base component is installed on top of the adjustable base components. The first clamping component includes a first stabilizing base, a first stake, a limiting baffle, a first limiting sleeve, a first clamping block, and a first knob. The bottom of the first stabilizing base is symmetrically and vertically integrated with a first stake. A limiting baffle is vertically installed on the top of the side of the first stabilizing base away from the vertical central axis of the track base. A first limiting sleeve is horizontally installed on the top of the first stabilizing base, and first clamping blocks are symmetrically arranged inside the first limiting sleeve. A first knob is horizontally connected and installed on the side of the first clamping block away from the vertical central axis of the first limiting sleeve.

[0006] Furthermore, the adjusting seat component includes a movable seat, a docking hole, a damping slider, and a positioning bolt. The movable seat has a docking hole vertically and symmetrically opened at the top center, and the bottom of the movable seat is horizontally connected to a damping slider. The positioning bolts are horizontally threaded and installed at the center of both the left and right sides of the damping slider.

[0007] Furthermore, the movable seat and the damping slider are fixedly connected, and the track seat and the damping slider are connected to each other by a slotted embedded structure. Moreover, the bottom surface of the track seat is provided with equally spaced vertical holes for bolt installation.

[0008] Furthermore, the first knob has a horizontal thread that passes through the side of the first limiting sleeve, and the first stabilizing seat and the limiting baffle are arranged in an "L" shape.

[0009] Furthermore, the assembly frame includes an upper clamping ring frame, a lower clamping ring frame, a shock-absorbing pad, a fixed support leg, and a fixing bolt. The bottom of the upper clamping ring frame is connected to the lower clamping ring frame, and the opposite surfaces of the upper and lower clamping ring frames are covered with shock-absorbing pads. The bottom of the fixed support leg is symmetrically provided with the lower clamping ring frame, and the left and right sides of the upper and lower clamping ring frames are vertically threaded with fixing bolts.

[0010] Furthermore, the top joints of the fixed support and the limiting baffle are vertically provided with holes for bolt connection and fixing, and the fixed support and the lower clamping ring are integrated into one structure.

[0011] Furthermore, the second clamping seat component includes a second stabilizing seat, a second stake, a detection baffle, a second limiting sleeve, a second clamping block, and a second knob. The bottom of the second stabilizing seat is symmetrically and vertically integrated with the second stake, and the top of the second stabilizing seat away from the vertical central axis of the track seat is vertically provided with the detection baffle. The top of the second stabilizing seat is horizontally installed with the second limiting sleeve, and the second clamping block is inside the second limiting sleeve. At the same time, the second clamping block is horizontally connected and installed with the second knob on the side away from the vertical central axis of the second limiting sleeve.

[0012] Furthermore, the vertical height of the detection baffle is higher than that of the limiting baffle, and the second stabilizing seat and the detection baffle are arranged in an "L" shape. Moreover, the four diagonal corners of the connection between the top surfaces of the first stabilizing seat, the second stabilizing seat and the moving seat are vertically provided with holes for bolt connection and fixing.

[0013] This invention provides a device for detecting the length of an insulin pen plunger, which has the following advantages: 1. This utility model, through the combined arrangement of a first clamping component and a second clamping seat component, utilizes a first clamping block inside a first limiting sleeve to securely clamp one end of the insulin pen plunger, while a second clamping block inside a second limiting sleeve precisely fixes the other end of the insulin pen plunger. This double-end clamping design effectively prevents the plunger from shaking or shifting during the testing process, thereby significantly improving the accuracy of length detection. Furthermore, the first clamping component and the second clamping seat component achieve smooth sliding and precise positioning on the track seat through the damping slider in the adjusting seat component and the slotted embedded structure of the track seat. With the use of a positioning bolt, the user can flexibly adjust the distance between the two clamping components according to actual needs to adapt to the testing requirements of insulin pen plungers of different lengths, enhancing the versatility and ease of operation of the device. These structural features allow the device to quickly enter the testing state when faced with insulin pen plungers of different sizes without frequent changes to the testing device or complex adjustments, greatly improving testing efficiency.

[0014] 2. This utility model, through the structural design of the assembly frame, has its upper and lower clamping ring frames securely connected by fixing bolts. Furthermore, the internal shock-absorbing pads effectively absorb vibrations, protecting the laser rangefinder from external impacts and ensuring the stability and reliability of the measurement data. This is crucial for medical equipment requiring high-precision testing. In addition, the first stabilizing seat and the limiting baffle, as well as the second stabilizing seat and the detection baffle, all adopt an "L"-shaped structure design. This not only enhances the overall structural stability but also, by setting the detection baffle higher than the limiting baffle, provides a clear detection reference surface for the insulin pen plunger, facilitating rapid and accurate length measurement and further improving testing efficiency. Meanwhile, this design also facilitates observation and operation by operators during the testing process, improving overall ease of use. Furthermore, the equidistantly arranged hole structure on the bottom surface of the track seat provides multiple options for the fixed installation of the equipment. Whether in a laboratory environment or on the production line, a suitable fixing method can be found to ensure the stability of the equipment during the testing process and reduce measurement errors caused by equipment movement. Moreover, the hole structure at the connection between the first clamping component and the second clamping seat component and the top surface of the moving seat makes the connection between the entire clamping system and the adjusting seat component more robust, further enhancing the equipment's anti-interference ability during the testing process and providing a strong guarantee for high-precision testing.

[0015] 3. This utility model utilizes a modular structure among the track base, adjusting base component, first clamping component, assembly frame, laser rangefinder, and second clamping base component. For example, during assembly, the first stud on the first clamping component is embedded into the mating hole on the adjusting base component, and the second stud on the second clamping base component is also mated to another set of adjusting base components in the same manner. This modular design not only simplifies the equipment assembly process but also facilitates subsequent maintenance and component replacement. When a component malfunctions or needs upgrading, the user can quickly locate and replace the corresponding module without disassembling the entire equipment, greatly reducing maintenance and time costs. Furthermore, the modular structure makes the equipment more convenient to transport and store. Each component can be packaged and transported independently, and quickly assembled into a complete device upon arrival at the site, improving the overall efficiency and flexibility of the equipment.

[0018] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0019] like Figures 1 to 5 As shown, an insulin pen plunger length detection device includes a track base 1, a first clamping component 3, and a second clamping seat component 6. Adjustable seat components 2 are connected and installed on both the left and right ends of the track base 1. The first clamping component 3 is installed on top of a set of adjustable seat components 2, and an assembly frame 4 is installed in the middle of the top of the first clamping component 3. A laser rangefinder 5 is horizontally installed inside the assembly frame 4. The second clamping seat component 6 is installed on top of the adjustable seat components 2. The first clamping component 3 includes a first stabilizing seat 301, a first insert 302, a limiting baffle 303, and a first limiting sleeve 304. The first clamping block 305 and the first knob 306 are included. The bottom of the first stabilizing base 301 is symmetrically and vertically integrated with first inserts 302. A limit baffle 303 is vertically installed on the top of the side of the first stabilizing base 301 away from the vertical central axis of the track seat 1. A first limiting sleeve 304 is horizontally installed on the top of the first stabilizing base 301. The first clamping blocks 305 are symmetrically arranged inside the first limiting sleeve 304. A first knob 306 is horizontally connected to the side of the first clamping block 305 away from the vertical central axis of the first limiting sleeve 304. The adjusting base component 2 includes a sliding... The moving base 201 includes a mating hole 202, a damping slider 203, and a positioning bolt 204. The moving base 201 has symmetrically arranged vertical mating holes 202 at its top center, and the bottom of the moving base 201 is horizontally connected to the damping slider 203. Positioning bolts 204 are threaded horizontally onto the center of both sides of the damping slider 203. The moving base 201 and the damping slider 203 are fixedly connected. The track seat 1 and the damping slider 203 are connected by a slotted embedded structure. The bottom surface of the track seat 1 has equally spaced vertically arranged holes for bolt installation. The first knob 306 is horizontally threaded through the side of the first limiting sleeve 304, and the first stabilizing seat 301 and the limiting baffle 303 are arranged in an "L" shape. The first knob 306 is used to adjust the first clamping block 305 horizontally, which can flexibly adjust the clamping distance of the first clamping block 305 according to the actual diameter of the insulin pen plunger. This ensures that the first clamping block 305 can firmly and accurately clamp one end of the insulin pen plunger. This adjustable clamping method greatly enhances the adaptability of the device to insulin pen plungers of different specifications and improves the versatility and accuracy of the test.

[0020] like Figures 1 to 5As shown, the assembly frame 4 includes an upper clamping ring frame 401, a lower clamping ring frame 402, a shock-absorbing pad 403, a fixed support leg 404, and a fixing bolt 405. The bottom of the upper clamping ring frame 401 is connected to the lower clamping ring frame 402, and the surfaces of the upper clamping ring frame 401 and the lower clamping ring frame 402 on opposite sides are covered with shock-absorbing pads 403. The bottom of the fixed support leg 404 is symmetrically provided with the lower clamping ring frame 402, and the left and right sides of the upper clamping ring frame 401 and the lower clamping ring frame 402 are vertically threaded with fixing bolts 405. The fixed support leg 404 and the limit stop are also included. The top joint of plate 303 is vertically provided with holes for bolt connection and fixing, and the fixing leg 404 and the lower clamping ring frame 402 are integrally formed. The second clamping seat component 6 includes a second stabilizing seat 601, a second insert 602, a detection baffle 603, a second limiting sleeve 604, a second clamping block 605, and a second knob 606. The bottom of the second stabilizing seat 601 is symmetrically and vertically provided with the second insert 602, and the top of the side of the second stabilizing seat 601 away from the vertical central axis of the track seat 1 is vertically provided with the detection baffle 603. Furthermore, a second limiting sleeve 604 is horizontally mounted on the top of the second stabilizing seat 601, and a second clamping block 605 is installed inside the second limiting sleeve 604. A second knob 606 is horizontally connected to the side of the second clamping block 605 away from the vertical central axis of the second limiting sleeve 604. The vertical height of the detection baffle 603 is higher than that of the limiting baffle 303. The second stabilizing seat 601 and the detection baffle 603 are arranged in an "L" shape. Moreover, the four diagonal points at the junction of the top surfaces of the first stabilizing seat 301, the second stabilizing seat 601, and the moving seat 201 are all vertical. The device has a hole structure for bolt connection and fixing. The upper clamping ring 401 and lower clamping ring 402 of the assembly frame 4 are fastened together by fixing bolts 405, forming a stable and reliable installation space. This provides a solid support for the laser rangefinder 5. The internal shock-absorbing pads 403 can effectively absorb the vibration generated during the operation of the equipment, avoid interference with the laser rangefinder 5 due to vibration, and ensure that the laser rangefinder 5 can continuously and stably output measurement data, thereby providing an accurate and reliable basis for the length detection of the insulin pen plunger.

[0021] In summary, as Figures 1 to 5 As shown, when using this insulin pen plunger length detection device, the device is first securely installed on the laboratory workbench or a designated position on the production line by utilizing the equally spaced holes on the bottom surface of the track base 1, ensuring that the device will not be displaced due to external forces during the detection process. Subsequently, according to the length specifications of the insulin pen plunger to be tested, the damping slider 203 in the adjusting seat component 2 is used to slide and adjust on the track seat 1 so that the distance between the first clamping component 3 and the second clamping seat component 6 reaches a suitable range, and the positioning bolt 204 is used for precise positioning to prevent slippage during the testing process. Next, place one end of the insulin pen plunger into the first limiting sleeve 304 of the first clamping member 3. By rotating the first knob 306, drive the first clamping block 305 to move inward until it firmly clamps one end of the plunger. Similarly, place the other end of the plunger into the second limiting sleeve 604 of the second clamping member 6. Rotate the second knob 606 to make the second clamping block 605 clamp the other end of the plunger. At this time, the insulin pen plunger is horizontally fixed between the two clamping members, and one end of the plunger is in close contact with the detection baffle 603, and the other end is in close contact with the limiting baffle 303, providing a clear reference surface for length measurement. Subsequently, the laser rangefinder 5 inside the assembly rack 4 is activated. The laser beam is emitted from the transmitting end, reflected by the surface of the detection baffle 603, and returns to the receiving end. The laser rangefinder 5 calculates the round-trip time of the laser to accurately obtain the length data of the push rod, which is displayed on the display screen of the equipment. The operator can quickly obtain the length information of the insulin pen push rod by observing the value on the display screen and complete the detection task. During the entire detection process, the shock-absorbing pad 403 inside the assembly rack 4 effectively absorbs the vibration from the outside, protects the laser rangefinder 5 from impact, and ensures the stability and reliability of the measurement data. During structural maintenance, users can independently inspect and replace different modules of the equipment. If wear is found on the first clamping component 3 or the second clamping seat component 6, the clamping module can be removed as a whole by disassembling the fixing bolts at the connection between the first stabilizing seat 301, the second stabilizing seat 601 and the moving seat 201, replacing the new components, and reinstalling. There is no need to disassemble the track seat 1 or the adjusting seat component 2. For maintenance of the assembly frame 4, simply loosen the fixing bolts 405 on both sides of the upper clamping ring frame 401 and the lower clamping ring frame 402 to separate the upper and lower ring frames, and inspect or replace the internal shock-absorbing pads 403. If the laser rangefinder 5 malfunctions, it can be directly removed from the assembly frame 4, replaced with a new device of the same model, and quickly restored to use. Maintenance of the adjusting seat component 2 is the same. This modular design is convenient. If the damping slider 203 becomes stuck, the positioning bolt 204 can be removed to slide the moving seat 201 off the track seat 1, allowing the damping slider 203 to be cleaned or replaced. If the equally spaced holes on the bottom surface of the track seat 1 wear down due to long-term use, this can be resolved by replacing the fixing bolts or adjusting the installation position. This modular design allows the equipment to be maintained without the need for professional tools or complex operations. Ordinary operators can complete most maintenance tasks, greatly shortening equipment downtime and reducing maintenance costs. At the same time, the independent packaging and transportation characteristics of each module also facilitate the protection of the equipment during storage or transportation, avoiding damage to components due to collisions or squeezing, further improving the overall service life and reliability of the equipment.
