Description

Technical Field

[0001] The utility model relates to the technical field of livestock measuring rulers, in particular to a livestock body measuring ruler with a folding structure. Background Art

[0002] A livestock body measurement tape is a tool specifically used to measure livestock body size. The results are often used to assess livestock growth, production performance, and feeding management. This measurement tool typically includes a ruler for length and height, and a tape measure or soft ruler for girth. Livestock body measurement tapes not only assess livestock growth and health, but also provide a basis for genetic improvement and breeding decisions.

[0003] However, some existing livestock body measurement rulers cannot be flexibly adjusted to their size, significantly reducing their adaptability and making them suitable only for animals of a certain size. When faced with larger or smaller animals, these rulers cannot effectively perform their functions and cannot meet all measurement needs. This not only limits their practicality but also places an additional burden on livestock workers, as they need to prepare a variety of measuring tools of different sizes to adapt to different measurement scenarios. In addition, non-adjustable size rulers may lead to inaccurate measurement data. If the measuring ruler used does not match the animal's size, the measured data may have large errors, affecting the reliability of the data. In fields that require accurate data, such as animal breeding selection and nutritional management, such errors can have a significant impact, thereby affecting the final decision and results. Therefore, in response to the above shortcomings, a livestock body measurement ruler with a folding structure is proposed to solve the above problems. Utility Model Content

[0004] In order to make up for the above shortcomings, the present invention provides a livestock body measurement ruler with a folding structure, aiming to improve the problem in the prior art that some livestock body measurement rulers cannot be adjusted in size during use, resulting in a smaller adaptability range.

[0028] The front sides of the two rotating rods 2 are fixedly connected to the connecting columns 7, and the outsides of the two connecting columns 7 are rotatably connected to the connecting frames 8. The front sides of the two connecting frames 8 are fixedly connected to the arc-shaped clamping rods 9. The arc-shaped clamping rods 9 are the parts of the measuring ruler that directly contact the livestock. Their arc-shaped design can better adapt to the body curves of the livestock and reduce discomfort during measurement. The proximal sides of the two arc-shaped clamping rods 9 are fixedly connected to the card balls 10, and the far sides of the two fixed columns 3 are provided with card assembly for engagement and positioning. The main function of the card ball 10 is to increase the friction during clamping to ensure the stability of the livestock during the measurement process.

[0029] Reference Figures 2 to 4, the two positioning components include a fixed block 11, the adjacent sides of the two fixed blocks 11 are fixedly connected to the distant sides of the two fixed columns 3, the tops of the two fixed blocks 11 are fixedly connected with sleeves 12, the interiors of the two sleeves 12 are slidably connected with a card column 13, the sleeve 12 is used to accommodate the card column 13, and provides a sliding path for the card column 13 so that it can move up and down smoothly, and the exteriors of the two card columns 13 are fixedly connected with a fixing ring 14, which ensures the stability of the card column 13 during movement and acts as a It is the connection point of the spring 15, which provides resilience for the clamping column 13. The outside of the fixed ring 14 is slidably connected to the inside of the sleeve 12. The outside of the two clamping columns 13 are both sleeved with a spring 15. One end of the spring 15 is fixedly connected to the inner top side of the sleeve 12, and the other end of the spring 15 is fixedly connected to the top of the fixed ring 14. The spring 15 provides a downward force for the clamping column 13 to keep it in the appropriate position, and helps the clamping column 13 return to its initial position after the pull plate 16 is released. The tops of the two clamping columns 13 are both fixedly connected to the pull plate 16;

[0030] When the length needs to be adjusted, the operator pulls the pull plate 16 to drive the card column 13 to move up or down to the required position. The adjacent sides of the two fixed rings 14 are fixedly connected to the connecting plate 17. The outer side of the connecting plate 17 is slidably connected to the inside of the sleeve 12. The front sides of the two connecting plates 17 are fixedly connected to the movable plate 18. The bottoms of the two movable plates 18 are fixedly connected to the guide frame 19. The function of the guide frame 19 is to keep the movable plate 18 and the card column 20 moving on the correct path to prevent deviation. When the pull plate 16 is pulled, the connecting plate 17 moves accordingly, thereby driving the movable plate 18 and the guide frame 19 to move together. The outer side of the guide frame 19 is slidably connected to the rotating rod 2 Internally, the bottom of the two movable plates 18 are fixedly connected with a second clamping column 20. The function of the second clamping column 20 is to insert into the first clamping slot 22 after the first clamping column 13 is pulled to the appropriate position and locked, thereby fixing the connecting frame 8 and the arc-shaped clamping rod 9 in the required position to adapt to livestock of different sizes. The tops of the two arc-shaped clamping rods 9 are each provided with a second clamping slot 21. The outside of the first clamping column 13 is slidably connected to the inside of the second clamping slot 21. The tops of the two connecting frames 8 are each provided with a first clamping slot 22. The outside of the second clamping column 20 is slidably connected to the inside of the first clamping slot 22. When the second clamping column 20 moves with the movable plate 18, it will be inserted into the first clamping slot 22, thereby locking the position of the connecting frame 8 and completing the adjustment of the measuring ruler length.

[0031] Working principle: When it is necessary to measure the size of small livestock such as chickens, the pull plate 16 can be pulled to drive the fixed ring 14 and the clamping column 13 to move, thereby compressing the spring 15, and at the same time drive the connecting plate 17 and the movable plate 18 to move. At this time, the clamping column 20 can be disengaged from the inside of the clamping groove 1 22, and then the connecting frame 8 can be rotated to drive the arc clamping rod 9 and the clamping ball 10 to rotate. At this time, the arc clamping rod 9 and the clamping ball 10 can be rotated to the outside of the rotating rod 2, and the clamping groove 21 is aligned with the clamping column 13. At the bottom of the measuring rod 16, the pull plate 16 can be released, and the elastic force of the spring 15 can be reset to allow the clamping column 13 to engage with the inside of the clamping groove 21. At this time, the length of the measuring ruler can be reduced, and the body size of small livestock such as chickens can be measured by rotating the rod 2. The livestock can be clamped by rotating the rod 2, which will cause the measuring scale 6 to rotate outside the fixed column 3 and the limit frame 5 to rotate. At the same time, the measuring scale 6 slides inside the limit frame 5, and the measured body size can be determined by the reading on the surface of the measuring scale 6. When it is necessary to measure large livestock such as cattle and sheep, the connecting frame 8 and the arc-shaped clamping rod 9 can be reset to maximize the length of the measuring ruler, thereby enabling the volume measurement of large livestock.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
