[0002] Uneven shoulders are a common phenomenon among teenagers. Due to various habits such as sitting posture, walking, carrying bags, and nutritional intake, teenagers develop improper postures, which over time can lead to uneven shoulders. Uneven shoulders not only affect the posture and appearance of teenagers, but also have a significant negative impact on the development of the spine and muscles, and may even cause psychological problems, greatly hindering their healthy growth.

[0003] Therefore, uneven shoulders in adolescents should be detected and corrected as early as possible. Early detection and appropriate corrective measures are crucial for prevention and treatment.

[0025] Firstly, see [the following] Figures 1 to 6 The diagram shows a cantilever assembly for measuring uneven shoulders as described in this application. The cantilever assembly includes a housing 1, a main support structure 2, a position adjustment structure 3, a laser emitter 4, and a slide rail 5. The slide rail 5 is fixedly mounted on the uneven shoulder measuring device. The main support structure 2 is fixedly mounted on the position adjustment structure 3. The position adjustment structure 3 is movably mounted on the slide rail 5 to drive the main support structure 2 to move along the slide rail 5. The laser emitter 4 is fixedly mounted on the main support structure 2 and is in a horizontal direction to emit a laser towards the side closer to the subject. The housing 1 is sleeved on the main support structure 2, and a through hole 11 is provided on the housing 1 at a position corresponding to the laser emitter 4 so that the laser emitted by the laser emitter 4 can be emitted through the through hole 11.

[0026] In this embodiment, during use, two cantilever components provided by this invention are correspondingly mounted on the frame of the uneven shoulder measuring device. The two cantilever components are positioned to correspond to the two acromions of the subject, with the two laser emitters 4 facing each other. During the uneven shoulder measurement process, the position adjustment structure 3 drives the main support structure 2 to move along the slide rail 5 on the frame. The laser emitters 4 mounted on the main support structure 3 emit laser light horizontally to determine the height of the subject's acromions. In use, the position adjustment structure 3 moves the lasers emitted by the two laser emitters 4 to the two acromions of the subject, thereby accurately obtaining the height information of the two acromions to detect whether the subject has uneven shoulders. This invention solves the technical problem in the prior art where positioning components are mostly rods, which loosen after long-term use, leading to inaccurate measurement results and adversely affecting uneven shoulder detection.

[0027] Furthermore, the main support structure 2 and the laser emitter 4 are protected by the housing 1, extending the service life of the cantilever assembly.

[0028] Optionally, refer to Figure 5 The main support structure 2 of this utility model includes a connecting seat 21 and an installation body 22 that are connected to each other; the connecting seat 21 is fixedly connected to the position adjustment structure 3; an installation groove 23 is horizontally provided on the installation body 22, and the installation groove 23 is used to fix the laser emitting component 4.

[0029] In this embodiment, the laser emitter 4 is fixedly installed horizontally in the mounting groove 23 on the mounting body 22 to ensure that the laser emitter 4 can emit laser light horizontally toward the side of the subject. At the same time, the connecting seat 21 can be fixedly connected to the position adjustment structure 3 by bolts or other fasteners.

[0030] Furthermore, the mounting body 22 may also be provided with a weight-reducing groove 24 to reduce the weight of the mounting body 22 and prevent it from sagging under the action of gravity during use.

[0031] Optionally, refer to Figure 5 The mounting body 22 of this utility model is provided with a plurality of set screw holes 221, and the set screw holes 221 are arranged in pairs on the upper and lower sides of the mounting groove 23; a set screw is provided in the set screw hole 221, and the set screw abuts against the laser emitting element 4 through the set screw hole 221.

[0032] In this embodiment, a set screw hole 221 is provided on the mounting body 22. Through the set screw hole 221 and the set screw, the laser emitter 4 can be finely adjusted in vertical angle after installation, so that the laser emitted by the laser emitter 4 is in the horizontal direction, which facilitates accurate positioning of the acromion of the subject.

[0033] Optionally, refer to Figure 2 The housing 1 in this utility model includes a front housing 12 and a rear housing 13. The front housing 12 and the rear housing form a cavity and are fitted onto the main support structure 2. The front housing 12 is detachably connected to the mounting body 22 by bolts. The rear housing 13 is detachably connected to the position adjustment structure 3 by bolts.

[0034] In this embodiment, the housing 1 includes a front housing 12 and a rear housing 13, which are detachably connected and installed by bolts. During use or maintenance, the front housing 12 and the rear housing 13 can be disassembled for repair or component replacement.

[0035] Furthermore, refer to Figure 4 The front housing 12 can also be equipped with a control button 121, which is electrically connected to the central control component of the uneven shoulder measuring device. During use, the control button 121 can send an electrical signal to the central control component of the uneven shoulder measuring device, and the distance measuring component of the uneven shoulder measuring device can collect the height of the two cantilever arms respectively, and measure and judge the uneven shoulders of the person being measured based on the height of the two cantilever arms.

[0036] Specifically, the housing 1 may be made of plastic, rubber, or other lightweight materials known to those skilled in the art.

[0037] Optionally, refer to Figure 6The position adjustment structure 3 of this utility model includes a mounting plate 31 and a damping component 32. The mounting plate 31 is provided with a mounting screw hole 311 for fixing the connecting seat 21. The mounting plate 31 is also provided with a connector for fixing the slider on the slide rail 5. The damping component 32 is fixedly mounted on the mounting plate 31 and is located close to the slide rail 5. The damping component 32 has a damped state and an undamped state. When the damping component 32 abuts against the slide rail 5, the damping component 32 is in the damped state. When the damping component 32 is separated from the slide rail 5, the damping component is in the undamped state.

[0038] Furthermore, the mounting plate 31 is also provided with a wiring channel 312, through which the wiring of the laser emitter 4 and the reset button 121 on the housing 1 are electrically connected to the central control component of the height and shoulder measuring device.

[0039] Furthermore, refer to Figure 6 The mounting screw hole 311 can be selected as a combination of a circular screw hole and multiple arc-shaped screw holes. The multiple arc-shaped screw holes are symmetrically arranged around the circular screw hole. During use, the connecting seat 21 and the mounting body 22 can rotate around the circular screw hole by connecting the fasteners through the arc-shaped screw holes, thereby realizing the adjustment of the pitch angle of the laser emitter 4. In long-term use, when the device becomes loose or ages, the pitch angle of the laser emitter 4 can be adjusted to adapt to more usage scenarios, so that the laser emitter 4 is in a horizontal state, ensuring the accuracy of the measurement results.

[0040] Optionally, refer to Figure 9 and Figure 6 In this utility model, a friction plate 51 is provided on the slide rail 5; the damping component 32 includes a base frame 321, a fixing block 322 and a damping friction rod 323; the base frame 321 is fixedly installed on the mounting plate 31; the fixing block 322 is fixedly installed on the base frame 321; the damping friction rod 323 is movably connected to the fixing block 322. When the damping friction rod 323 abuts against the friction plate 51, the damping component 32 is in a damped state; when the damping friction rod 323 is separated from the friction plate 51, the damping component 32 is in a non-damped state.

[0041] In this embodiment, the damping state of the damping member 32 is adjusted by the relationship between the damping friction rod 323 on the damping member 32 and the friction plate 51. Specifically, during the position adjustment of the position adjustment structure 3, the position adjustment structure 3 can be moved to a position close to the required height, and then the damping member 32 provides damping to the position adjustment structure 3. At this time, the position adjustment structure 3 is then fine-tuned with damping. During the fine-tuning process, the damping prevents the position adjustment structure 3 from moving too fast and affecting the accuracy.

[0042] Optionally, refer to Figure 8The damping friction rod 323 of this utility model includes a main shaft 323-1, a pull rod 323-2, a friction part 323-3, and a limiting part 323-4. The main shaft 323-1 passes through the fixing block 322, and both ends of the main shaft 323-1 extend from the fixing block 322, allowing relative rotation between the main shaft 323-1 and the fixing block 322. The pull rod 323-2 and the friction part 323-4 are fixedly mounted on one end of the main shaft 323-1, and the limiting part 323-4 is fixedly mounted on the other end of the main shaft 323-1. The pull rod 323-2 is used to drive the main shaft 323-1 and the friction part 323-3 to rotate. When the friction part 323-3 abuts against the friction plate 51, the damping element 32 is in a damped state, and when the friction part 323-3 separates from the friction plate 51, the damping element 32 is in a non-damped state.

[0043] In this embodiment, the main shaft 323-1 is axially limited by the limiting part 323-4 to prevent it from moving axially during the rotation of the main shaft 323-1; the main shaft 323-1 and the friction part 323-3 are rotated by the pull rod 323-2, so that the friction part 323-3 switches with the state of the friction plate 51 to switch the state of the damping member 32.

[0044] Optionally, refer to Figure 7 The damping friction rod 323 in this utility model also includes a return spring 323-5; the two ends of the return spring 323-5 are respectively connected to the mounting plate 31 and the friction part 323-3; when the return spring 323-5 is in a natural equilibrium state, the friction part 323-3 is separated from the friction plate 51.

[0045] In this embodiment, the damping friction rod 323 also includes a return spring 323-5. The return spring 323-5 resets the friction part 323-3. After use, the pull rod 323-2 is released, and the friction part 323-3 can be reset under the action of the return spring 323-5. At this time, the damping is eliminated, and the position adjustment structure 3 can be moved over a wide range.

[0046] Optionally, the included angle between the friction part 323-3 and the pull rod 323-2 in this utility model is 120 degrees to 150 degrees.

[0047] In this embodiment, the included angle between the friction part 323-3 and the pull rod 323-2 is 120 degrees to 150 degrees, which prevents the pull rod 323-2 from colliding with other components during use.

[0048] Secondly, this utility model also provides a height and shoulder measurement device, characterized in that it includes a frame and any of the above-mentioned cantilever components for measuring height and shoulder; the cantilever components are mounted on the frame via slide rails.

[0049] In this embodiment, a shoulder height measurement device is provided. It should be noted that the cantilever assembly in this embodiment has the same structure as the cantilever assembly in the above embodiments, and its beneficial effects are also the same, so it will not be described again here.
