Description

Body ruler

technical field

The utility model relates to a measuring tool, in particular to a body measuring ruler capable of measuring the height and body length of animals.

Background technique

All kinds of animals need to know their various technical indicators in the process of breeding and observation research. Among them, long-term measurement of animal growth and physical characteristics is the most basic research method. Existing tools for measuring animals are mainly soft measuring rulers or round measuring sticks, which are used to measure the bust, height, body length, and even neck circumference and leg circumference of animals. Although the soft ruler is easy to use, soft and flexible, However, since the measurement object is an animal, it cannot cooperate like a human being. It is not easy to grasp the stability of the animal during measurement, and the soft ruler needs to be close to the body and stationary to measure accurately, which makes the measurement process time-consuming and laborious, and it is not easy to obtain satisfactory measurement results. , which brings trouble to use, especially for tall horses, the measurement of the soft ruler cannot be completed by one person sometimes, which increases the difficulty of measurement. Although the circular measuring rod is a special measuring tool, there are defects in the structural design, and the measurement data needs to be converted to obtain, which is inconvenient to use and has low precision. Designing a better and more convenient tool that can be used for animal measurement is the problem to be solved by the utility model.

Detailed ways

Below in conjunction with accompanying drawing 1, Fig. 2, Fig. 3 the utility model is further described:

The body measuring ruler described in the utility model comprises a telescopic measuring stick and a fixed scale 4 and a sliding scale 5 connected on the measuring stick. The measuring stick is divided into a fixed part 1 and a telescopic part 2, and the fixed part 1 and the telescopic part 2 The cross-sectional shape is elliptical, and the elliptical cylindrical fixed part 1 corresponds to the telescopic part 2 and is connected through the T-shaped guide rail 6. Under the action of the T-shaped guide rail 6, the telescopic part 2 can be stretched up and down, increasing the The measurement range of the measuring rod is defined, and the marking on the scale on the measuring rod starts from the bottom end of the fixed part 1. The fixed scale 4 and the sliding scale 5 are located on the side of the T-shaped guide rail 6 between the fixed part 1 and the telescopic part 2. The fixed scale 4 and the sliding scale 5 are connected to the end of the fixed part 1 of the measuring rod and the telescopic shaft through the rotating shaft 7, 7'. On the sliding bracket 3 of the part 2, the fixed scale 4 and the sliding scale 5 are hidden between the fixed part 1 and the telescopic part 2 at ordinary times. When opened, the inner surface of the fixed scale 4 is flush with the bottommost surface of the fixed part 1 . The sliding bracket 3 can slide up and down along the telescopic part 2. There is a transparent body on the sliding bracket 3. The sliding bracket 3 is clamped on the telescopic part 2 of the measuring stick. The transparent part can display the scale on the surface of the telescopic part 2. come out. On the side of the rotating shaft 7 of the fixed scale 4, the fixed part 1 of the measuring rod is also provided with a positioning bead 8 and a positioning rod 9 for positioning the fixed scale 4. The positioning bead 8 is used to limit the fixed scale 4 to only be closed at 90°. Lifting and opening, the positioning rod 9 is used to solve the limit rotation problem after the fixed scale 4 is opened. Similarly, the slider 3 connected to the sliding scale 5 is also provided with a corresponding positioning touch bead 8' and a positioning rod 9', Its effect is identical with the location touch bead 8 and the location bar 9 beside the fixed scale 4. In order to determine the reliability of the stretching process of the telescopic part 2 of the measuring rod and the convenience of carrying, the upper and lower limit touch beads 13, 12, and the upper limit touch bead are respectively arranged on the positions close to the contact surface and the lower end of the T-shaped guide rail 6. 13 can ensure that the position of the telescopic part 2 can be locked when it is extended, so that the telescopic part 2 will not come out from the fixed part 1, the position of the telescopic part 2 and the fixed part 1 is connected accurately, and the measurement is convenient. After the telescopic part 2 shrinks, the lower limit bumper 12 can also lock the telescopic part 2 and the fixed part 1, so that the connecting structure of the two is stable and convenient for carrying. Certainly, the shapes of the fixed part 1 and the telescopic part 2 of the measuring rod can also be set as triangle, quadrangle or other shapes according to needs, or even a combination of two different shapes.

During the carrying process, the fixed scale 4 and the sliding scale 5 shrink between the telescopic part 2 and the fixed part 1 of the measuring stick, and are affected by the positioning bumpers 8, 8', the fixed scale 4 and the sliding scale 5 will not move from between the two. The lower limit bead 12 can also limit the position of the fixed part 1 and the telescopic part 2, so that the telescopic part 2 will not slide out on the fixed part 1. The measuring rod with elliptical cylindrical structure is stable in structure and easy to carry.

When it is necessary to measure the length of the animal body, the telescopic part 2 can be stretched, and the telescopic part 2 moves upward through the T-shaped guide rail 6. When reaching the top of the fixed part 1, the upper limit touch bead 13 on the contact surface of the guide rail 6 will move the telescopic part 2 and fixed part 1 position locking. Operate the fixed scale 4 and use the rotating shaft 7 to rotate out from the end of the fixed part 1. During the rotation, the fixed scale 4 will press down the positioning bumper 8. After the rotation is in place, the positioning bumper 8 will pop up again, and the popped up positioning bumper 8 makes the fixed scale 4 not turn back again, and its opening angle just remains at 90 °, and the positioning rod 9 that is positioned at the rear side of the fixed scale 4 then blocks the rotation angle of the scale to prevent the fixed scale 4 from continuing to rotate forward. The inner surface of the fixed scale 4 in place is flush with the surface of the bottom end of the fixed part 1 of the measuring rod, so that the true and accurate measurement values can be guaranteed without further conversion. Equally, sliding ruler 5 also launches by this process, but sliding ruler 5 is to be connected on the sliding bracket 3, and the reading of sliding ruler 5 can observe conveniently from the transparent body of sliding bracket 3. Adjust the position of the sliding bracket 3 on the telescopic part 2 of the measuring rod, and use the two protruding rulers to be stuck on the position required for the measurement of the animal, so that the body length of the animal can be measured conveniently.

When it is necessary to measure the height of the animal body, the fixed scale 4 can be put away accordingly, and the positioning touch bead 8 will block the fixed scale 4 and hide it inside the fixed part 1, which will not affect the use of the measuring stick. Since the scale on the measuring rod is calculated from the bottom of the fixed part 1, it is only necessary to place the measuring rod vertically on the side of the animal body, move the sliding bracket 3, and press the sliding scale 5 on the animal body to complete the height measurement process.
