[0031] 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.

[0032] Reference Figure 1 , Figure 6 , Figure 7 and Figure 8This utility model provides an embodiment of a height-adjustable child medical examination seat, comprising a main body 1, which is the child seat body. The bottom end of the main body 1 is provided with a support leg 2. An adjustment component is provided between the main body 1 and the support leg 2 to adjust the height of the seat according to the child's height. The adjustment component includes an adjustment block 24 that drives the main body 1 to rise. The lower part of the adjustment block 24 is movably inserted into the inner wall of the support leg 2. The inner wall of the left rear surface of the adjustment block 24 is provided with a tooth groove 29 that meshes with a gear 23. The middle part of the support leg 2 is rotatably provided with a gear 23 that meshes with the tooth groove 29. The upper part of the support leg 2 is fixedly connected with a fixing rod 22 that supports the gear 23 and a limiting rod 28. The outer wall of the right part of the fixing rod 22 is rotatably connected to the gear 23. The gear 23 meshes with the tooth groove 29 and can cooperate with the limiting rod 28 to limit the downward movement of the adjustment block 24. The upper part of the fixing rod 22 is provided with a sliding groove 211 that provides space for the slider 210 to slide.

[0033] Furthermore, a pressing block 25 is slidably connected to the upper rear surface of the support leg 2, which drives the guide block 26 to move downward. A guide block 26 is fixedly connected to the front surface of the pressing block 25, which drives the slider 210 to move downward. A slide groove 212 is provided in the middle of the support leg 2 to provide space for the guide block 26 to slide up and down. Slider blocks 210 are fixedly connected to both the left and right sides of the guide block 26, which drive the limiting rod 28 to move downward and slide out of the limiting groove 27 to release the limiting of the gear 23. A limiting rod 28 is fixedly connected to the top right side of the slider 210, which slides into the limiting groove 27 to limit the gear 23 and the tooth groove 29 to the adjusting block 24. The direction of the downward movement of the adjusting block 24 is limited by the insertion of the limiting rod 28 into the limiting groove 27.

[0034] Reference Figure 1 and Figure 5 The right side of the main body 1 is provided with a protective component to prevent children from shaking and falling during the physical examination. The protective component includes a handrail 3 to block children and prevent them from falling. The right side of the handrail 3 is threaded with a threaded rod 31 to fix the handrail 3 to the main body 1. The left and right sides of the main body 1 are provided with handrails 3, threaded rods 31 and positioning blocks 32, which can protect the two sides of the main body 1.

[0035] Reference Figure 2 , Figure 3 and Figure 4A spring 21 is elastically connected between the bottom of the guide block 26 and the support leg 2. After being squeezed by the guide block 26, the guide block 26 is quickly reset by the reverse force of the squeeze. One end of the spring 21 is fixedly connected to the bottom middle part of the slider 210, and the other end of the spring 21 is fixedly connected to the upper inner wall of the support leg 2. The guide block 26 is slidably connected in the sliding groove 212 in the middle of the support leg 2. The slider 210 is slidably connected to the inner wall of the fixed rod 22. The top end of the limiting rod 28 extends out of the fixed rod 22 and extends towards the inner wall of the gear 23. Multiple sets of limiting grooves 27 are radially and equidistantly opened on the inner wall of the gear 23.

[0036] Reference Figure 6 , Figure 7 and Figure 8 The guide block 26 is slidably connected to the inner wall of the second slide groove 212, and the slider 210 is slidably connected to the inner wall of the first slide groove 211. The rear surface of the limiting rod 28 is set as an inclined surface. By setting it as an inclined surface, when the gear 23 rotates and drives the limiting groove 27 to rotate, it can squeeze the inclined surface of the limiting rod 28, causing the limiting rod 28 to move downward, driving the slider 210 and the guide block 26 to move downward and squeeze the spring 21. The reverse force of the spring 21 being squeezed can cause the slider 210 and the guide block 26 to reset, driving the limiting rod 28 to quickly reset and insert into the limiting groove 27. By matching the top end of the limiting groove 27 with the top end of the limiting rod 28, the gear 23 can be rotated in the opposite direction to limit it. At this time, the gear 23 can be prevented from rotating in the opposite direction, thereby preventing the main body 1 and the adjusting block 24 from moving downward. At this time, the main body 1 can be quickly adjusted upward to increase the height of the main body 1. The top end of the limiting rod 28 is used to abut in one of its limiting grooves 27.

[0037] Reference Figure 1 and Figure 5 The right side of the main body 1 is fixedly connected to a positioning block 32, which allows the handrail 3 to move stably up and down. The handrail 3 is slidably connected to the right side of the positioning block 32. The left side of the threaded rod 31 is threadedly connected to the right side of the positioning block 32. The positioning block 32 is set in a T shape. Setting it in a T shape can increase the stability of the handrail 3's movement. After the handrail 3 is raised to the top, the threaded rod 31 will move inward after being threadedly connected to the handrail 3. After contacting the right side of the positioning block 32, the threaded connection will fix the handrail 3 to the right side of the positioning block 32.

[0038] Working principle: When the height of the main body 1 needs to be adjusted, the main body 1 is moved upward. The main body 1 drives the adjusting block 24 to move upward together. Since the inner wall of the left rear surface of the adjusting block 24 has a toothed groove 29, which meshes with the gear 23, the upward movement of the adjusting block 24 will drive the gear 23 to rotate. The rotation of the gear 23 will press the inclined surface of the limiting rod 28, causing the limiting rod 28 to move downward, which will drive the slider 210 and the guide block 26 to move downward and press the spring 21. When the main body 1 is moved upward to the appropriate position, the reverse force of the spring 21 being pressed will cause the slider 210 and the guide block 26 to reset, which will drive the limiting rod 28 to reset, so that the limiting rod 28 inserts into the corresponding limiting groove 27 and limits the reverse rotation of the gear 23. At this time, the downward movement of the adjusting block 24 and the main body 1 is limited, preventing the main body 1 from moving downward, thereby fixing the position between the adjusting block 24 and the support leg 2, realizing the upward adjustment of the seat height.

[0039] When the height of the main body 1 needs to be lowered, press the pressing block 25 on the upper part of the rear surface of the support leg 2. The pressing block 25 slides downward, causing the guide block 26 to move downward together and compress the spring 21. When the guide block 26 moves downward, the slider 210 on its right side also moves downward. The slider 210 causes the limiting rod 28 to move downward, thereby causing the limiting rod 28 to slide out of the limiting groove 27 in the gear 23. As the limiting rod 28 slides out of the limiting groove 27, the limiting of the gear 23 is released. At this time, the main body 1 is moved downward, so that the gear groove 29 can drive gear 23 to rotate, and gear 23 is not limited. When the desired height position is adjusted, release the pressing block 25. At this time, the spring 21 at the bottom of the guide block 26 will push the guide block 26 to reset upward due to the reverse elastic force generated by the compression. This will drive the guide block 26, slider 210 and limit rod 28 to reset upward, so that they are re-inserted into the corresponding limit groove 27, and lock gear 23 again, thereby fixing the position between the adjusting block 24 and the support leg 2, and realizing the adjustment of the seat's downward movement height.

[0040] When the height of the handrail 3 needs to be adjusted, the tightness between the threaded rod 31 and the positioning block 32 is adjusted by rotating the threaded rod 31. The threaded rod 31 is then turned out of the positioning block 32, which releases the limit of the handrail 3. Moving the handrail 3 downwards can remove the protection. When protection is needed, after moving the handrail 3 upwards to the top, the threaded rod 31 is rotated again to connect with the threaded connection of the handrail 3 and then moved inwards to connect with the threaded connection of the positioning block 32, thus quickly limiting the handrail 3 again. The adjustment is relatively convenient and quick. Since the positioning block 32 is T-shaped, it can provide a stable sliding track for the handrail 3, ensuring the stability of the handrail 3 during the adjustment process. By moving the handrail 3 upwards, a safety protection function to prevent children from falling is provided, improving the safety and convenience of children's physical examination.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
