Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] The purpose of the present invention is to provide a measuring rod for measuring livestock body size based on laser to solve the problems existing in the prior art, such as low measurement efficiency and accuracy, small amount of data collected, and large deviation in collection results caused by manual reading.

[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1 to 3 As shown, the present invention provides a measuring rod for measuring livestock body size based on laser, comprising a main rod 1, a first support rod 3 and a second support rod 4, wherein one end of the main rod 1 is used for detachably mounting a laser rangefinder 10, for example, by bolt connection or snap connection, and a laser emission port 12 is provided on one side of the laser rangefinder 10 close to the other end of the main rod 1, and the laser emitted by the laser emission port 12 extends in the same direction as the main rod 1, that is, the laser light is parallel to the main rod 1. By detachably connecting the laser rangefinder 10 to the main rod 1, the two can be separated after use, thereby facilitating storage and carrying; and a charging port 13 is provided on the laser rangefinder 10 for easy use; preferably, the laser rangefinder 10 adopts a digital display laser rangefinder 10, and the measurement length data is determined by the digital display laser rangefinder 10, and its digital display screen 11 can display the measurement data, thereby improving the measurement speed, facilitating reading, and reducing the error of manual measurement, and a reading key 14 is provided on the digital display laser rangefinder 10, and the corresponding measurement value is obtained by pressing the reading key 14.

[0021] Among them, the first support rod 3 is installed on the main rod 1 and is perpendicular to the main rod 1, and the first support rod 3 is flush with the laser emission port 12, so that the first support rod 3 corresponds to the laser emission port 12. Then, when measuring the body characteristics of livestock, the first support rod 3 can be attached to the body surface of the livestock, and it can serve as the starting end of the measurement, that is, the emission end of the laser emission port 12, to ensure the accuracy of the measurement; the second support rod 4 is arranged on the same side as the first support rod 3 and is parallel to the first support rod 3. The second support rod 4 can be movably installed on the main rod 1 along the extension direction of the main rod 1, and can be detachably matched with the main rod 1, and the second support rod 4 is used to block the transmission path of the laser.

[0022] The present invention discloses a measuring rod for measuring livestock body dimensions based on lasers. Before measuring the body dimensions of livestock, a laser rangefinder 10 is first mounted on a main rod 1. When measuring the height of livestock, the main rod 1 is set vertically with its bottom end supported on the ground. A first support rod 3 is placed on the livestock's beard and nails. The laser rangefinder 10 is turned on. With the ground as a reference point, the laser emitted from the laser emission port 12 is directed toward the ground. The laser rangefinder 10 is then read to obtain the livestock's height. When measuring other body dimensions of livestock, a second support rod 4 is mounted on the main rod 1. The first support rod 3 and the second support rod 4 are respectively placed at two points to be measured. With the second support rod 4 as a reference point, the laser emitted from the laser emission port 12 is directed toward the second support rod 4. The laser rangefinder 10 is then read to obtain other body dimension data of the livestock. This method can solve the problems of low measurement efficiency and accuracy, small amount of data collected, and large deviations in the collected results caused by manual readings in the prior art.

[0023] In this embodiment, the first support rod 3 and the second support rod 4 are both rod-shaped structures with a rectangular cross-section, so that the sides of the first support rod 3 and the second support rod 4 can fit the body surface of the livestock. At the same time, since the cross-sections of the first support rod 3 and the second support rod 4 are both rectangular structures, their right-angled edges can better resist deformation, thereby ensuring the accuracy of measurement using the first support rod 3 and the second support rod 4.

[0024] In a specific embodiment, an extension rod 8 is further included, which extends in the same direction as the main rod 1 and is movably mounted on the main rod 1. The extension rod 8 is extended or retracted from the end of the main rod 1 not provided with the laser rangefinder 10. The extension rod 8 can be used to extend the length of the main rod 1, thereby enriching the items that can be measured for body size and being applicable to livestock of different sizes. For example, when measuring short livestock such as sheep, the main rod 1 can be used alone to complete the measurement, while when measuring tall livestock such as cattle, the main rod 1 and the extension rod 8 can be used in combination. In order to generally adapt to livestock of different sizes, the effective length of the main rod 1 and the extension rod 8 is preferably 90 cm. When the extension rod 8 is fully extended, the total measurement range of the main rod 1 and the extension rod 8 can reach 180 cm. In this embodiment, the second support rod 4 can be movably installed on the extension rod 8 along the extension direction of the extension rod 8, and can be detachably matched with the extension rod 8. That is, according to different usage scenarios, the second support rod 4 can be installed on the main rod 1, or the second support rod 4 can be installed on the extension rod 8, so as to achieve the effectiveness of measuring livestock of different sizes.

[0025] In a specific embodiment, the main rod 1 has a hollow structure, the extension rod 8 is slidably inserted into the main rod 1, and the end of the main rod 1 where the laser rangefinder 10 is not provided is provided with an opening for the extension rod 8 to extend or retract, so that the extension rod 8 can be built into the main rod 1 and can move in the main rod 1, which not only facilitates the measurement of livestock of different sizes, but also facilitates the storage of the main rod 1 and the extension rod 8 for easy carrying.

[0026] In a specific embodiment, it also includes a first sliding accessory 6 and a second sliding accessory 9. The first sliding accessory 6 is movably mounted on the main rod 1 along the direction in which the main rod 1 extends, and is located on the side of the laser rangefinder 10 where the laser emission port 12 is provided; the second sliding accessory 9 is movably mounted on the extension rod 8 along the direction in which the extension rod 8 extends; the second support rod 4 is used to be detachably mounted on the first sliding accessory 6 or the second sliding accessory 9, so as to utilize the first sliding accessory 6 and the second sliding accessory 9 to be mounted on the surface of the main rod 1 and the extension rod 8, and to be used for sliding setting, and the second support rod 4 is respectively mounted on the first sliding accessory 6 and the second sliding accessory 9 to realize the measurement of different body size items.

[0027] In a specific embodiment, the first sliding accessory 6 and the second sliding accessory 9 both include a main structure, one end of the main structure is slidably sleeved on the main rod 1 or the extension rod 8, and the other end is provided with a card slot that is plugged into the second support rod 4. The main structure of the first sliding accessory 6 and the main structure of the second sliding accessory 9 are respectively slidably sleeved on the main rod 1 and the extension rod 8 to ensure the stability of the two main structures sliding on the main rod 1 and the extension rod 8 respectively, and the card slot is used to complete the fixation of the second support rod 4, so that the second support rod 4 is not easy to shake during the movement, thereby ensuring the accuracy of the measured value.

[0028] In this embodiment, the end of the main structure that cooperates with the main rod 1 or the extension rod 8 is a ring structure or a U-shaped groove structure, so that it can be matched with the main rod 1 and the extension rod 8 respectively, and can slide up and down after clamping the main rod 1 and the extension rod 8.

[0029] In a specific embodiment, both the main rod 1 and the extension rod 8 are provided with scale lines 2. Before measuring the body size of livestock, the laser rangefinder 10 is installed on the main rod 1 and turned on. The second support rod 4 is installed on the main rod 1 or the extension rod 8. By sliding the second support rod 4 to different positions, readings are taken with the laser rangefinder 10, and then the interval value between the first support rod 3 and the second support rod 4 is read through the scale lines 2 on the main rod 1 and the extension rod 8. By comparing this interval value with the measurement result of the laser rangefinder 10, the body size of the livestock can be measured only when the two are consistent, so as to ensure the accuracy of the measurement results.

[0030] In this embodiment, the laser emission port 12 of the laser rangefinder 10 and the first support rod 3 are parallel to the zero scale line 2 of the main rod 1, so that data can be read directly through the position of the second support rod 4, ensuring the convenience and accuracy of the reading data.

[0031] In a specific embodiment, a recessed area is provided on the main rod 1 and the extension rod 8, and the recessed area is extended along the extension direction of the main rod 1 and the extension rod 8. The scale line 2 is provided in the recessed area to prevent the sliding of the second support rod 4 from causing wear to the scale line 2 during use, or in the technical scheme of setting the first sliding accessory 6 and the second sliding accessory 9, since the first sliding accessory 6 and the second sliding accessory 9 are respectively slidably installed on the surfaces of the main rod 1 and the extension rod 8, by setting the recessed area on the surface of the main rod 1 and the extension rod 8, the scale line 2 is in the recessed area, so that the first sliding accessory 6 and the second sliding accessory 9 can avoid wear on the scale line 2 in the recessed area during the sliding process, and it is convenient to read while increasing the service life.

[0032] In a specific embodiment, the end of the main rod 1 for mounting the first support rod 3 is provided with a fixing accessory 5, and the first support rod 3 is detachably mounted on the side of the fixing accessory 5 facing away from the main rod 1. For example, a card slot is provided on the fixing accessory 5, and the first support rod 3 is installed in the card slot to complete the connection with the fixing accessory 5. After use, the first support rod 3 is taken out of the card slot for easy storage and carrying. The laser rangefinder 10 is detachably mounted on the fixing accessory 5 to ensure the installation position requirements of the laser rangefinder 10. For example, the laser rangefinder 10 is installed on the fixing accessory 5 so that when the second support rod 4 is not needed, the laser emitted by the laser rangefinder 10 can be avoided from being blocked by the first sliding accessory 6 or the second sliding accessory 9.

[0033] In this embodiment, the fixing accessory 5 is provided with a socket 7, such as a Type-C socket 7, for mounting and securing the laser rangefinder 10. The laser rangefinder 10 is provided with an interface, and the socket 7 on the fixing accessory 5 and the interface on the laser rangefinder 10 can be tightly plugged and matched, ensuring the stability of the installation of the laser rangefinder 10 and thus ensuring accurate readings. In addition, as an option, the fixing accessory 5 is also provided with an anti-falling mechanism, such as a jackscrew, which can be used to tighten the laser rangefinder 10 to further ensure the stability of the installation of the laser rangefinder 10. The laser rangefinder 10 can also be secured with a cable tie.

[0034] In a specific embodiment, a positioning surface is provided on the side of the fixing fitting 5 near the extension rod 8. The positioning surface is perpendicular to the direction in which the main rod 1 extends. The laser rangefinder 10 has an overall cubical structure, with two adjacent side surfaces abutting the positioning surface and the main rod 1, respectively. When the laser rangefinder 10 is installed, the outer structure of the laser rangefinder 10 can be directly utilized to mate with the fixing fitting 5 and the main rod 1, respectively, so that the laser emitting port 12 of the laser rangefinder 10 can emit laser light along the direction in which the main rod 1 extends. In this embodiment, after the interface on the laser rangefinder 10 is plugged into and mated with the socket 7 on the fixing fitting 5, the two side surfaces of the laser rangefinder 10 can abut against the positioning surface and the main rod 1, respectively, completing the installation of the laser rangefinder 10.
