[0033] The embodiment of the utility model provides a plant size measuring device, which is convenient for measuring fruits, vegetables, plants and the like with irregular outer contours, thereby improving the measurement efficiency.

[0034] Combine the following Figure 1-Figure 4 The technical solution provided by the utility model is described in more detail.

[0035] like Figure 1-Figure 4As shown, the plant size measuring device provided in this embodiment includes a box body 1, a moving component, a limiting rod body 3, a laser ranging sensor 5, a control unit and a display unit, wherein: the moving component is slidably connected to the box body 1, the moving component includes a reflecting part 23 and a moving rod body 21 connected to each other, the moving rod body 21 is located outside the box body 1, and the reflecting part 23 is located inside the box body 1. When the moving component moves toward the limiting rod body 3, the moving rod body 21 and the limiting rod body 3 are used to clamp the opposite sides of the part to be measured; the laser ranging sensor 5 is located in the box body 1, and the emitting end of the laser ranging sensor 5 is arranged toward the reflecting part 23, and the reflecting part 23 is used to reflect laser. The control unit is electrically connected to the laser ranging sensor 5 and the display unit, and the display unit is used to display measurement data.

[0036] Among them, the laser ranging sensor 5 is an existing mature accessory and can be purchased directly from the market; the display unit includes a display screen, which is not shown in the figure. The laser ranging sensor 5, the control unit and the display unit are electrically connected through wires. The control unit can convert the electrical signal of the laser ranging sensor 5 into a digital signal and transmit the digital signal to the display unit. The display unit displays the digital signal for the measurer to read and stores it in a common format through software.

[0037] The limiting rod 3 and the emitting end of the laser distance sensor 5 are located on the same vertical line, the laser emitted by the laser distance meter is reflected by the reflecting part 23 and returned, and the control unit calculates the distance between the limiting rod 3 and the moving rod 21 through the propagation distance of the laser. Alternatively, the limiting rod 3 and the emitting end of the laser distance sensor 5 are located on the same vertical line, so that when the control unit calculates the distance between the limiting rod 3 and the fixed rod, it only needs to add or subtract the distance between the emitting end of the laser distance sensor 5 and the limiting rod 3. The control unit is preset with a program to calculate the distance between the limiting rod 3 and the fixed rod.

[0038] See also Figure 1 As shown, the measuring button 6 of the laser distance measuring sensor 5 is arranged on the box body, which is convenient for the user to start. The measuring button 6 completes one-key measurement and storage through software. The measuring button 6 can complete the measurement of several values ​​in a fixed order, and execute the storage command after measuring the required values.

[0039] In the plant size measuring device of this embodiment, when the moving rod 21 moves toward the limiting rod 3, the moving rod 21 can clamp the opposite sides of the part to be measured with the limiting rod 3. Since the moving rod 21 and the limiting rod 3 are in a rod-shaped structure, it is convenient to extend into the irregular parts to be measured of irregular fruits, vegetables and plants. The laser emitted by the laser ranging sensor 5 is reflected by the reflecting part 23, and the control unit can calculate the distance between the moving rod 21 and the limiting rod 3 according to the transmission distance of the laser, thereby converting the electrical signal into a digital signal, so that the measurement data is displayed on the display unit; the above-mentioned plant size measuring device is convenient for measuring fruits, vegetables, plants and the like with irregular outer contours, and improves the measurement efficiency.

[0040] As an alternative embodiment, see Figure 2 As shown, the moving assembly also includes a moving seat 20 and a slider 22, wherein: the moving rod body 21, the slider 22, and the reflecting part 23 are all fixed on the moving seat 20, the slider 22 is located in the box body 1, and a slide rail 4 is provided in the box body 1. The slide rail 4 extends along the length direction of the box body 1, and the slider 22 is slidably connected to the slide rail 4.

[0041] See also Figure 2 , a part of the moving seat 20 extends into the box body 1, and the slider 22 is fixed to the part of the moving seat 20 located in the box body 1, such as by welding, screw fixing, etc., a part of the moving seat 20 is located outside the box body 1, and the moving rod body 21 is fixed to the part of the moving seat 20 located outside the box body 1. When measuring, the operator holds and pushes the moving seat 20, and through the matching structure of the slider 22 and the slide rail 4, the moving seat 20 moves more smoothly, which is convenient for the moving rod body 21 and the limit rod body 3 to cooperate with each other, such as Figure 3 shown.

[0042] As an alternative embodiment, see Figure 2 As shown, the reflecting part 23 includes a reflecting plate, which is fixed to the part of the moving seat 20 located in the box body 1, such as by screws, welding, etc., and the middle part of the reflecting plate is located on the same straight line as the emitting end of the laser ranging sensor 5.

[0043] The laser emitted by the laser ranging sensor 5 hits the reflective plate and then returns, so that the control unit can calculate the distance between the limit rod 3 and the moving rod 21 according to the moving distance of the laser. Wherein, the reflective plate and the limit rod 3 are located on the same vertical line, or the reflective plate and the limit rod 3 are not located on the same vertical line, in which case the control unit should consider the distance between the reflective plate and the limit rod 3 when calculating.

[0044] As an alternative embodiment, see Figure 1 As shown, an opening slot 13 is provided on the side of the box body 1 , and the opening slot 13 extends along the length direction of the box body 1 . At least a portion of the movable seat 20 passes through the opening slot 13 and extends into the box body 1 .

[0045] A part of the movable seat 20 extends into the opening slot 13 to be fixedly connected with the slider 22, and another part is located outside the box body 1 to fix the movable rod 21. The above structure facilitates the measurer to push the movable seat 20 so that the movable seat 20 can be slidably connected with the box body 1.

[0046] As an alternative embodiment, see Figure 1 As shown, a brush portion 14 is provided on the side wall of the opening slot 13 to prevent dust from entering the box body 1. The brush portion 14 can prevent impurities such as plant leaves and juice from entering the housing during the measurement process, prevent the slider 22 from sliding, and ensure accurate measurement.

[0047] As an alternative embodiment, see Figure 1 As shown, the moving rod body 21 includes a horizontal section 212 and a vertical section 211 that are fixedly connected. One end of the horizontal section 212 is fixedly connected to the moving seat 20, and the vertical section 211 is used to cooperate with the limiting rod body 3 to clamp the part to be measured.

[0048] The reflective plate and the vertical section 211 are located on the same vertical line, or the reflective plate and the vertical section 211 of the limiting rod 3 are not located on the same vertical line. In this case, the control unit should consider the distance between the reflective plate and the vertical section 211 during calculation.

[0049] The vertical section 211 can cooperate with the limiting rod 3 to be clamped on two opposite sides of the part to be measured. Figure 3 As shown, the vertical section 211 is connected to the side wall of the moving base 20 through the horizontal section 212. The structure of the horizontal section 212 enables the vertical section 211 to be located on one side of the moving base 20 to prevent the moving base 20 from affecting the vertical section 211 from extending into the part to be tested.

[0050] As an optional embodiment, the limiting rod 3 is detachably connected to the box body 1. The limiting rod 3 can be threadedly connected to the box body 1, or detachably connected via a locking member such as a screw.

[0052] The measurer can choose whether to install the extension section 7 according to actual conditions, which can increase the measuring range.

[0053] As an optional embodiment, a magnetic attraction portion is provided at one or both ends of the box body 1, and the end of the extension section 7 is attracted to the magnetic attraction portion, thereby being fixedly connected to the box body 1. The magnetic attraction portion may be a magnet or other component, which facilitates the installation and removal of the extension section 7 and the box body 1. Specifically, the magnetic attraction portion such as a magnet may be fixed to the end of the box body by gluing or snapping.

[0054] See also Figure 4 As shown, when the extension section 7 is connected to the limiting rod body 3, the limiting rod body 3 and the extension section 7 are threadedly connected, or are detachably connected by a locking member such as a screw. At this time, a program can be preset in the control unit, and when the control unit calculates the distance between the vertical section 211 of the moving rod body 21 and the limiting rod body 3, the distance between the output end of the laser distance measuring sensor 5 and the limiting rod body 3 is increased according to the transmission distance of the laser.

[0055] As an optional embodiment, the box body 1 includes a bottom box 11 and a cover body 12, and the bottom box 11 and the cover body 12 are detachably connected, so as to facilitate the inspection and disassembly of the components in the box body 1, such as the slider 22 and the laser ranging sensor 5.

[0056] See also Figure 5 and Figure 6 As shown, in another embodiment, a clamping plate 8 is rotatably connected to the box body 1, and the clamping plate 8 is used to buckle on the upper surface of the box body 1, so as to cooperate with the box body 1 to clamp the object to be tested 9.
