Description

Technical Field

[0001] This utility model relates to the field of height measurement equipment technology, and in particular to an electric lifting height measurement device. Background Technology

[0002] In fields such as healthcare, sports training, and child growth monitoring, height measurement is a fundamental and crucial testing procedure. Traditional height measurement tools are mostly manual, resulting in low efficiency and poor accuracy. With technological advancements, electrically operated height-lifting height measurement devices have become increasingly common. These devices automatically raise and lower the measuring components via a motor, significantly improving measurement convenience. However, existing equipment still has shortcomings in transmission stability, measurement accuracy, and structural reliability. For example, hospital pediatric clinics need to measure the height of a large number of children daily; traditional equipment is cumbersome to operate and prone to measurement errors due to human factors. In sports training, real-time and accurate acquisition of athletes' height data is crucial for developing training programs, but existing electric devices often experience jamming or measurement deviations due to mechanical structural problems. Therefore, developing more efficient and stable electrically operated height-lifting height measurement devices is of significant practical importance.

[0003] There are two main types of existing height measurement equipment: manual and automatic rack and pinion. The manual type relies on manual operation, and the person measuring needs to align the height ruler with the person being measured and take the reading. The rack and pinion type uses a motor to drive the gear to rotate, and the gear meshes with the rack, so that the measuring component moves along the rack in a straight line to achieve the height measurement.

[0004] However, existing electric lifting height measuring devices generally suffer from poor transmission stability. During the measurement process, the gears and racks are prone to wear after long-term use, affecting transmission stability. In addition, the installation accuracy requirements are high, and even a slight deviation may lead to transmission failure. During measurement, the measuring components are prone to shaking and jamming, which in turn affects the measurement accuracy. This makes it difficult for existing devices to meet the needs of high-precision height measurement. Therefore, an electric lifting height measuring device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an electric lifting height measuring device, which aims to improve the problem that the measuring components are prone to shaking and jamming during measurement in the prior art, thus affecting the measurement accuracy and making it difficult for the existing equipment to meet the requirements of high-precision height measurement.

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

[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 Figures 1-4 This utility model provides an embodiment of an electric lifting height measuring device, including a measuring platform 1, which allows users to easily stand on it for measurement. A support frame 2 is provided on one side of the measuring platform 1, and a scale plate 3 is provided on one side of the support frame 2. The scale plate 3 is marked with precise scale lines and is slidably connected inside the measuring platform 1. The support frame 2 is rotatably connected to two symmetrical rotating columns 4. Rotating wheels 5 are fixedly connected to the outer walls of the two rotating columns 4. Synchronous belts 6 are directly provided on the two rotating wheels 5. The rotating wheels 5 are driven by a motor 7 and connected to the synchronous belt 6 to ensure that the two sides move synchronously during the lifting and lowering of the device. A motor 7 is fixedly connected to one side of the support frame 2, and the output end of the motor 7 is connected to one of the rotating wheels 5. A slide 8 is fixedly connected to one side of the synchronous belt 6 and is slidably connected inside the support frame 2. The function of the slide 8 is to connect the scale plate 3 to the measuring rod 11 to ensure that it lifts and lowers smoothly in the vertical direction. A sliding component is provided on one side of the slide 8, and a connecting component is provided on the side wall of the scale plate 3.

[0035] The sliding assembly includes pulley 9, which is rotatably connected to one side of the slide frame 8. Pulley 10 is rotatably connected to the other side of the slide frame 8. Both pulley 9 and pulley 10 are slidably connected inside the support frame 2, ensuring smooth sliding of the slide frame 8 inside the support frame 2 and avoiding jamming. A measuring rod 11 is fixedly connected to one side of the slide frame 8. A groove 12 is opened inside the scale plate 3, and the measuring rod 11 is slidably connected inside the groove 12.

[0036] Reference Figures 2-5The connecting assembly includes a connecting block 14 and an insert block 15. One side of the connecting block 14 is fixedly connected to the side wall of the scale plate 3, and one side of the insert block 15 is fixedly connected to the other side of the connecting block 14. A fixed frame 13 is fixedly connected to one side of the support frame 2. The insert block 15 is slidably connected inside the fixed frame 13. Symmetrical sliding plates 16 are slidably connected inside the insert block 15. The sliding plates 16 provide support to ensure the insert block 15 can slide smoothly. A telescopic column 17 is provided between the two sliding plates 16. A spring 19 is sleeved on the outer wall of the telescopic column 17. Both ends of the spring 19 are fixedly connected to the inside of the two sliding plates 16. The elasticity of the spring 19 makes the scale plate 3 more stable after fixing and allows for quick disassembly, improving the flexibility and ease of use of the equipment. Each of the slide plates 16 has a locking block 18 fixedly connected to one side. The locking block 18 is slidably connected inside the fixed frame 13. Through the cooperation between the locking block 18 and the fixed frame 13, the displacement of the insert block 15 during movement can be effectively prevented, thereby ensuring the stable assembly and disassembly of the scale plate 3. A push-pull rod 20 is slidably connected inside the fixed frame 13. A baffle 21 is fixedly connected to one side of the push-pull rod 20. A limit block 22 is fixedly connected to one side of the baffle 21. The limit block 22 is in contact with the locking block 18. When it is necessary to disassemble the scale plate 3, the user only needs to pull the push-pull rod 20. The push-pull rod 20 will drive the baffle 21 and the limit block 22 to move together. The limit block 22 will push the locking block 18, causing it to overcome the elastic force of the spring 19 and retract, thereby releasing the locking of the fixed frame 13. This design makes disassembling the scale plate 3 simple and efficient.

[0037] Working principle: When using this electric lifting height measuring device, the person being measured stands on the measuring platform 1. First, the motor 7 is started, and its output drives the connected rotating wheel 5 to rotate. Since the two rotating wheels 5 are connected by a synchronous belt 6, the other rotating wheel 5 also rotates synchronously. The synchronous belt 6 moves under the drive of the rotating wheel 5, and the slide 8 is fixed to one side of the synchronous belt 6. Therefore, the slide 8 will move up and down in a straight line inside the support frame 2 along with the synchronous belt 6. During the movement of the slide 8, pulley 1 9 and pulley 2 10... The pulleys 9 and 10 serve as guides and supports, respectively rotatably connected to both sides of the slide 8 and can slide inside the support frame 2. They ensure the stability of the slide 8 when it moves up and down, reducing shaking and frictional resistance. At the same time, the measuring rod 11 fixed on one side of the slide 8 slides in the groove 12 of the scale plate 3, further assisting the movement guidance of the slide 8, so that the measuring rod 11 can move accurately along the direction of the scale plate 3. By observing the scale value corresponding to the measuring rod 11 on the scale plate 3, the height data of the subject can be obtained.

[0038] When it is necessary to disassemble and assemble the support frame 2 and the scale plate 3, first attach the scale plate 3 to one side of the support frame 2, so that the insert 15 on the side wall of the scale plate 3 is inserted into the fixed frame 13 on the side wall of the support frame 2. At this time, the locking block 18 inside the insert 15 is forced to slide inward, and the locking block 18 is forced to compress the spring 19. When the connecting block 14 and the fixed frame 13 are fully attached, the spring 19 releases the force and rebounds, thereby driving the locking block 18 to lock in the fixed frame 13 to complete the fixation. When disassembling, pull the push-pull rod 20. The push-pull rod 20 drives the baffle 21 and the limiting block 22 to move. The limiting block 22 pushes the locking block 18 to overcome the elastic force of the spring 19, so that the locking block 18 retracts into the insert 15, releasing the lock on the fixed frame 13, and thus completing the disassembly.

[0039] 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.
