Description

Technical Field

[0001] This utility model relates to the field of assessment and testing technology, and in particular to a pull-up assessment and testing device. Background Technology

[0002] With the increasing demand for standardization and intelligentization of physical fitness assessment standards, pull-up testing devices are gradually shifting from traditional manual monitoring to automated testing equipment. These devices integrate sensors, cameras, and AI algorithms to achieve standardized judgment of movements, automatic counting, and data management. They are widely used in school physical education tests, military training, and professional physical fitness assessments. However, existing technologies still have room for improvement in balancing testing accuracy and ease of operation. In particular, the need for rapid deployment and dynamic adjustment of the devices has not been fully met in large-scale assessment scenarios.

[0003] Existing pull-up testing devices typically employ a fixed mechanical structure and basic sensing technology. The mechanical structure mainly includes a bar at a fixed height and a sensor module mounted on the bar. The sensors are used to detect whether the user's chin exceeds the bar or changes in arm strength, thereby determining whether the movement is effective. The data processing module is usually embedded in the main body of the device, responsible for analyzing sensor data and recording the test results. The user interface is mostly a simple display screen or buttons used to display test data and operate the equipment.

[0004] However, the detection heads of existing devices typically use bolt-fixed or snap-fit ​​structures, requiring tools such as screwdrivers for installation and disassembly, resulting in low deployment efficiency in the testing room. For example, in scenarios where multiple devices are tested in parallel, the installation of each detection head takes about 5 to 10 minutes, and maintenance requires power off, which seriously affects the continuity of the assessment process. In addition, traditional fixing methods are difficult to adapt to dynamic adjustment requirements. For example, when temporarily replacing a faulty module or adjusting the detection angle, the position needs to be recalibrated, further extending the preparation time. Therefore, a pull-up assessment device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a pull-up assessment device, which aims to improve the problem that the detection head of the pull-up assessment device in the prior art requires tools for installation and disassembly, resulting in low efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pull-up assessment device includes a test bar and a detection head. An interactive panel is provided on the left side of the test bar, and a connecting component is provided on the top of the detection head.

[0008] The connecting component includes a connecting block, the bottom of which is fixedly connected to the top of the detection head. The connecting block is slidably connected to the outer wall of the assessment bar. The connecting block has symmetrical slots on both sides inside. A connecting plate is slidably connected to the top of the connecting block. A symmetrical connecting shaft is slidably connected inside the connecting plate. A transmission shaft is slidably connected inside the connecting shaft. A spring is provided on the outer wall of the transmission shaft. One end of the spring is fixedly connected to the side wall of the transmission shaft, and the other end is fixedly connected to the inner wall of the connecting shaft. Symmetrical limiting posts are fixedly connected to the outer wall of the transmission shaft. The limiting posts are all engaged with the slots. An adjustment component is provided at the bottom of the interactive panel.

[0009] As a further description of the above technical solution:

[0010] The adjustment assembly includes a sliding rod and a support rod. The top end of the sliding rod is fixedly connected to the bottom of the interactive panel, and the support rod is slidably connected to the outer wall of the sliding rod.

[0011] As a further description of the above technical solution:

[0012] A collar is fixedly connected to the top of the support rod, and the collar is slidably connected to the outer wall of the sliding rod.

[0013] As a further description of the above technical solution:

[0014] The bottom end of the support rod is fixedly connected to a support plate, and the sliding rod has multiple limiting grooves inside.

[0015] As a further description of the above technical solution:

[0016] The outer wall of the collar is fixedly connected with symmetrical fixed columns, and each fixed column is slidably connected with a transmission column.

[0017] As a further description of the above technical solution:

[0018] One end of the transmission column is rotatably connected to a transmission block, and the other end of the transmission column is fixedly connected to a conical block, which fits into the limiting groove.

[0019] As a further description of the above technical solution:

[0020] An extrusion disc is fixedly connected to the outer wall of the transmission column, and the outer wall of the extrusion disc is slidably connected to the inner wall of the fixed column.

[0021] As a further description of the above technical solution:

[0022] A second spring is provided on the outer wall of the transmission column. One end of the second spring is in contact with one side of the extrusion plate, and the other end is in contact with the inner wall of the fixed column.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the number of pull-ups of the examinee is detected by the detection head. When installing the detection head, the transmission shaft is pressed and rotated. The transmission shaft squeezes the spring to cause elastic deformation. The transmission shaft drives the spring to rotate inside the slot to lock it. This achieves the effect of quick installation and removal of the detection head without tools, which solves the problem of low efficiency of detection head installation and removal caused by the reliance on tools in traditional devices. It significantly improves the efficiency of examination room deployment and maintenance.

[0025] 2. In this utility model, by moving the transmission block, the transmission column slides inside the fixed column, which further drives the conical block to disengage from the limiting groove to achieve unlocking. After unlocking, the operator pulls the sliding rod to make the sliding rod slide inside the support rod, thereby achieving the effect of quickly adjusting the height of the interactive panel. This solves the problem of user inconvenience caused by the fixed height of the interactive panel in traditional devices and improves the testing and adaptation efficiency for users of different heights.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 - Figure 3 The present invention provides an embodiment of a pull-up assessment device, which includes a test bar 1 and a detection head 2. The detection head 2 is used to detect the number of pull-ups performed by the examinee. An interactive panel 3 is provided on the left side of the test bar 1, and a connecting component is provided on the top of the detection head 2. The connecting component is used to facilitate the user to quickly install the detection head 2.

[0035] The connecting assembly includes a connecting block 4, which contacts the test bar 1 to ensure stable connection of the detection head 2. The bottom of the connecting block 4 is fixedly connected to the top of the detection head 2. The connecting block 4 is slidably connected to the outer wall of the test bar 1. The connecting block 4 has symmetrical slots 5 inside for connecting with other components to achieve stability of the connecting assembly. A connecting plate 6 is slidably connected to the top of the connecting block 4. Symmetrical connecting shafts 7 are slidably connected inside the connecting plate 6. A transmission shaft 8 is slidably connected inside the connecting shafts 7. The function of the transmission shaft 8 is to further transmit the operator's force to ensure rapid drive of the assembly. A spring 9 is provided on the outer wall of shaft 8. The function of spring 9 is to provide elastic restoring force for transmission shaft 8, ensuring that the component can quickly reset. One end of spring 9 is fixedly connected to the side wall of transmission shaft 8, and the other end is fixedly connected to the inner wall of connecting shaft 7. Symmetrical left and right limiting posts 10 are fixedly connected to the outer wall of transmission shaft 8. The limiting posts 10 are all engaged with the slots 5. Through the cooperation of the limiting posts 10 and the slots 5, the detection head 2 can be quickly installed and removed, ensuring the convenience of the operator. An adjustment component is provided at the bottom of the interactive panel 3. The adjustment component is used to facilitate the user to quickly adjust the height of the interactive panel 3.

[0036] Specifically, in scenarios requiring rapid deployment of multiple devices, dynamic adjustment of testing schemes, or emergency maintenance, testers perform pull-ups on the single bar 1. The testing head 2 monitors and records the number of pull-ups in real time. To ensure accurate and stable installation and timely disassembly of the testing head 2, the operator ensures that the connecting block 4 is tightly fitted to the outer wall of the single bar 1 during installation. Then, the operator places the connecting plate 6 on top of the connecting block 4 and presses the drive shaft 8. Under pressure, the drive shaft 8 slides downward along the connecting shaft 7, thereby squeezing the spring 9, causing it to undergo elastic deformation and store elastic potential energy. As the drive shaft 8 moves, the limiting post 10 slides into the slot 5. Once the limiting post 10 is fully inserted into the slot 5, the operator can rotate the drive shaft 8 to drive the limiting post 10 to rotate synchronously within the slot 5, thus achieving a rapid locking function. This ensures that the testing head 2 can be quickly and tool-free installed and disassembled, facilitating adjustments by the operator.

[0037] Reference Figure 4 and Figure 5 The adjustment component includes a sliding rod 11 and a support rod 12. The top end of the sliding rod 11 is fixedly connected to the bottom of the interactive panel 3, and the support rod 12 is slidably connected to the outer wall of the sliding rod 11. The function of the support rod 12 is to provide a stable sliding path for the sliding rod 11. A collar 13 is fixedly connected to the top end of the support rod 12, and the collar 13 is slidably connected to the outer wall of the sliding rod 11. A support plate 21 is fixedly connected to the bottom end of the support rod 12. The function of the support plate 21 is to contact the ground and provide stable support for the interactive panel 3. Multiple limiting grooves 15 are opened inside the sliding rod 11. The outer wall of the collar 13 is fixedly connected to left and right symmetrical fixed columns 14. A transmission column 16 is slidably connected inside each fixed column 14. The function of the transmission column 16 is to further drive the force of the operator and adjust the movement of subsequent components.

[0038] Specifically, when users have significant height differences or need to adapt to different testing scenarios, and the height of the interactive panel 3 needs to be adjusted to achieve quick adaptation and improve operational convenience and testing efficiency, the operator can move the transmission block 17. The movement of the transmission block 17 causes the transmission column 16 to slide inside the fixed column 14, thereby pushing the conical block 18 out of the limiting groove 15 to complete the unlocking. After unlocking, the operator can pull the sliding rod 11 to make it slide inside the support rod 12, thereby quickly adjusting the height of the interactive panel 3. This adjustment function allows the operator to adjust the height of the panel at any time as needed, ensuring the convenience and flexibility of operation.

[0039] Reference Figure 4 and Figure 5One end of the transmission column 16 is rotatably connected to a transmission block 17. The function of the transmission block 17 is to facilitate the operator to quickly drive the adjustment component. The other end of the transmission column 16 is fixedly connected to a conical block 18. The conical block 18 fits into the limiting groove 15. Through the cooperation of the conical block 18 and the limiting groove 15, the adjustment component can be quickly locked and unlocked. The outer wall of the transmission column 16 is fixedly connected to a pressing plate 19. The function of the pressing plate 19 is to further transmit power, so that the second spring 20 can be stably compressed and deformed. The outer wall of the pressing plate 19 is slidably connected to the inner wall of the fixed column 14. The outer wall of the transmission column 16 is provided with a second spring 20. The function of the second spring 20 is to provide the springback force for the adjustment component, so that the component can quickly return to its original position after movement. One end of the second spring 20 is in contact with one side of the pressing plate 19, and the other end is in contact with the inner wall of the fixed column 14.

[0040] Specifically, further, during the sliding process of the transmission column 16, the extrusion plate 19 will also slide synchronously inside the connecting block 4, thereby extruding the second spring 20, causing the second spring 20 to undergo elastic deformation and store elastic potential energy. When adjusted to a suitable height, the elastic potential energy of the second spring 20 pushes the conical block 18 to re-engage in the limiting groove 15, ensuring the stability and fixation of the interactive panel 3, preventing unnecessary displacement of the panel during use, thereby ensuring the high efficiency, safety and stability of the equipment in each stage of use.

[0041] Working Principle: When using this pull-up assessment device, the tester performs pull-ups on the test bar 1. The detection head 2 detects the movement, and the interactive panel 3 records the number of pull-ups in real time. During installation, the operator attaches the connecting block 4 to the outer wall of the test bar 1, then attaches the connecting plate 6 to the top of the connecting block 4. The operator presses the drive shaft 8, causing it to slide downwards inside the connecting shaft 7, thus compressing the spring 9. This causes the spring 9 to elastically deform and store elastic potential energy. The movement of the drive shaft 8 further drives the limiting post 10 into the slot 5. After the limiting post 10 is in the slot 5, the operator rotates the drive shaft 8, causing the limiting post 10 to rotate synchronously inside the slot 5, thus achieving rapid locking and ensuring the detection head 2... The interactive panel 3 can be quickly installed and disassembled without the need for tools. When different users are using the interactive panel 3 or when it needs to be stored, the operator can move the transmission block 17. The movement of the transmission block 17 will further drive the transmission column 16 to slide inside the fixed column 14. The sliding of the transmission column 16 will further drive the conical block 18 to disengage from the limiting groove 15 to unlock it. After unlocking, the operator can pull the sliding rod 11 to slide it inside the support rod 12, thereby quickly adjusting the height of the interactive panel 3. This allows the operator to adjust it at any time. While the transmission column 16 is sliding, it will also drive the compression plate 19 to slide synchronously inside the connecting block 4, thereby compressing the second spring 20. This will cause the second spring 20 to undergo elastic deformation and store elastic potential energy. When the height is adjusted to a suitable level, the elastic potential energy of the second spring 20 will push the conical block 18 back into the limiting groove 15 to lock it in place, ensuring the stability and storage of the interactive panel 3.
