[0001] This utility model relates to the field of measurement technology, and in particular to a dimension measuring mechanism for use in high temperature and high humidity environments. Background Technology

[0002] Dimensional measurement is the process of determining the geometric parameters of an object, and it is widely used in engineering, manufacturing, construction, scientific research, and daily life.

[0003] However, in existing technologies, ordinary steel will undergo thermal expansion under high temperature conditions, causing geometric parameters such as guide rail straightness and lead screw pitch to deviate from the design values, resulting in inaccurate measurement benchmarks. Moreover, in high humidity environments, metal surfaces are prone to electrochemical corrosion. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that thermal expansion causes geometric parameters such as guide rail straightness and lead screw pitch to deviate from the design value, resulting in inaccurate measurement reference. Therefore, this invention proposes a dimension measuring mechanism for use in high temperature and high humidity environments.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a size measuring mechanism for use in high temperature and high humidity environments, including a base, a lifting component installed on one side of the top of the base, a movable mechanism installed on the top of the lifting component, and two heat dissipation mechanisms installed on the top of the base.

[0006] The active mechanism includes a first sliding rod, a first moving component slidably connected to the surface of the first sliding rod, a second sliding rod mounted on one side of the bottom end of the first moving component, a second moving component slidably connected to the surface of the second sliding rod, and a second rotating block rotatably connected to the bottom of the second moving component;

[0007] The heat dissipation mechanism includes a slide rail, with support plates fixedly connected to both ends of the slide rail. A rack is fixedly connected to the side wall of the slide rail, and a gear is meshed with one side of the rack. A guide block is slidably connected to the inner side of the slide rail, and a movable frame is fixedly connected to one side of the guide block. A rotating platform is rotatably connected to the top of the movable frame.

[0008] Preferably, one end of the second rotating block is rotatably connected to a swing rod, and the bottom end of the swing rod is slidably connected to the first rotating block.

[0011] Preferably, a geared motor is installed at the bottom of the mobile frame, and the output end of the geared motor is fixedly connected to a gear.

[0012] Preferably, a fan is installed on the top of the rotating platform.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the first moving component and the second moving component, together with the first sliding rod and the sliding rod, achieve precise positioning of the measuring instrument body in the horizontal and vertical directions. Combined with the linkage structure of the swing rod and the rotating block, the angle can be freely adjusted to ensure high measurement accuracy even on complex surfaces. At the same time, the fan system achieves adjustable heat dissipation through the linkage of gears and racks, effectively copes with high temperature and high humidity environments, prevents data errors and system instability caused by thermal disturbances, and ensures long-term stable operation of the equipment and the reliability of measurement data.

[0015] 2.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-4 As shown, this utility model provides a size measuring mechanism for use in high temperature and high humidity environments, including a base 1, a lifting component 5 installed on one side of the top of the base 1, a movable mechanism 3 installed on the top of the lifting component 5, and two heat dissipation mechanisms 2 installed on the top of the base 1.

[0024] The active mechanism 3 includes a first sliding rod 35, a first moving component 34 slidably connected to the surface of the first sliding rod 35, a second sliding rod 36 installed on one side of the bottom end of the first moving component 34, a second moving component 37 slidably connected to the surface of the second sliding rod 36, and a second rotating block 33 rotatably connected to the bottom of the second moving component 37.

[0025] The heat dissipation mechanism 2 includes a slide rail 22, with support plates 21 fixedly connected to both ends of the slide rail 22. A rack 23 is fixedly connected to the side wall of the slide rail 22, and a gear 28 is meshed with one side of the rack 23. A guide block 27 is slidably connected to the inner side of the slide rail 22, and a movable frame 24 is fixedly connected to one side of the guide block 27. A rotating platform 26 is rotatably connected to the top of the movable frame 24.

[0026] The specific settings and functions of this embodiment will be described in detail below. During measurement, the first moving component 34 is driven to slide smoothly along the surface of the first sliding rod 35 in a set direction, thereby achieving precise horizontal movement of the measuring instrument body 4. At the same time, the second moving component 37 can also move on the surface of the second sliding rod 36, thereby cooperating with the first moving component 34 to adjust the vertical position of the measuring instrument body 4, giving the measuring instrument body 4 multi-dimensional and full-range adjustable characteristics, greatly improving operational flexibility and measurement coverage.

[0027] In addition, the swing arm 32 can swing relative to the second rotating block 33. Through its linkage with the first rotating block 31, the angle of the measuring instrument body 4 can be dynamically adjusted according to the shape of the object being measured or the measurement requirements, thereby ensuring that the measurement accuracy can still be maintained when measuring complex or irregular surfaces, and achieving efficient measurement from all angles.

[0028] During the measurement process, to prevent electronic components from overheating or the system measurement data from becoming unstable due to increased ambient temperature, the device is equipped with a fan 25 for active heat dissipation. During operation, the fan 25, driven by the rotation of gear 28 and meshing with rack 23, can smoothly move the movable frame 24 along the surface of slide rail 22, allowing the position of the fan 25 to be precisely adjusted according to the actual heat-generating area, effectively improving heat dissipation efficiency.

[0029] It can not only quickly reduce the temperature of the measurement area during measurement, but also effectively prevent sensor drift and data errors caused by thermal expansion and contraction or humidity interference in high temperature and high humidity environments, thus fully ensuring the long-term stable operation and data reliability of the main body of the measuring instrument 4 under various environmental conditions.

[0030] Example 2: Figures 2-4 As shown, a swing rod 32 is rotatably connected to one end of the second rotating block 33, and a first rotating block 31 is slidably connected to the bottom end of the swing rod 32. A measuring instrument body 4 is rotatably connected to one side of the first rotating block 31, and one end of the first sliding rod 35 is connected to the lifting assembly 5. The bottom end of the support plate 21 is fixedly connected to the base 1. A reduction motor 29 is installed at the bottom of the moving frame 24, and the output end of the reduction motor 29 is fixedly connected to the gear 28. A fan 25 is installed on the top of the rotating platform 26.

[0031] The overall effect of this embodiment is that the height adjustment of the entire movable mechanism 3 can be controlled by the measuring instrument body 4. By precisely controlling the vertical displacement of the movable mechanism 3, fine-tuning and positioning of the measuring instrument body 4 in the vertical direction can be achieved. This adjustment process can be flexibly adjusted according to the size, shape, or placement height of the actual measured object, ensuring that the measuring instrument body 4 is always in the most suitable measurement position. This effectively avoids data errors caused by positional deviations, further improving the stability and accuracy of the measurement and meeting the measurement needs under various working conditions.

[0032] Furthermore, the geared motor 29 drives the connected gear 28 to rotate. Since the gear 28 meshes with the rack 23, the rotating gear 28 causes the moving frame 24 on the rack 23 to move linearly in a set direction. This movement causes the guide block 27 mounted on the moving frame 24 to slide smoothly on the surface of the slide rail 22, thereby adjusting the position of the fan 25 to match the airflow requirements of the measurement or working area. Simultaneously, the rotating platform 26 mounted on the moving frame 24 also adjusts its angle, driving the fan 25 to rotate within a certain angle range. This allows the airflow direction to change flexibly according to actual working conditions, enhancing the airflow's adaptability to high temperature, high humidity, or dusty environments, and further improving the overall stability and reliability of the device.

[0033] The device's operation and working principle are as follows: During measurement, the measuring instrument body 4 moves along the surface of the first sliding rod 35, driven by the first moving component 34. Simultaneously, the second moving component 37 moves along the surface of the second sliding rod 36, allowing for flexible adjustment of the measuring instrument body 4's position. Furthermore, the swing rod 32 can rotate relative to the second rotating block 33 and cooperates with the first rotating block 31 to effectively ensure the measuring angle of the measuring instrument body 4, facilitating multi-directional and multi-angle dimensional measurements and improving the comprehensiveness and accuracy of the measurements.

[0034] During the measurement process, to avoid errors caused by excessive temperature, the fan 25 can effectively dissipate heat. During heat dissipation, the gear 28 rotates under the drive of the reduction motor 29 and meshes with the rack 23, causing the moving frame 24 to move smoothly along the surface of the slide rail 22. This, in turn, adjusts the position of the fan 25, achieving directional heat dissipation for different areas. Simultaneously, the rotating platform 26 can also drive the fan 25 to rotate, adjusting the airflow direction, thereby enhancing heat dissipation efficiency in high-temperature and high-humidity environments and preventing measurement errors caused by environmental factors affecting the measuring instrument body 4.

[0035] The measuring instrument body 4 can also achieve precise adjustment of the measuring height by controlling the height of the entire moving mechanism 3, which is convenient to adapt to the measured objects of different sizes and shapes, thereby ensuring the accuracy and stability of the measurement process.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
