Description
Technical Field
[0001] The utility model relates to the technical field of measuring tools, in particular to a grain length measuring device. Background Art
[0002] There is a Chinese invention patent with publication number CN 109579659 A, which discloses a measuring ruler for measuring the radial length of agricultural products.
[0003] The invention patent states in the technical issues that “at present stage, under the production environment conditions at the field, the main method and tool for measuring the radial length of agricultural products is to “manually use a ruler combined with visual judgment to estimate the position of the curved surface boundary at both ends”. The main problem is that it is difficult to manually visually judge the position of the curved surface boundary and the difference in human observation causes a large systematic error, which artificially increases the error and waste in the subsequent calculation, design, manufacturing and transportation links.”
[0004] Combined with the drawings in the specification of the invention patent Figure 1 and Figure 2 It can be clearly known that the "agricultural products" that need to be measured mentioned in the technical problem are grains (i.e. rice grains).
[0005] Therefore, combined with the technical problems in this invention patent, it can be known that the length of the grains needs to be measured using a measuring device, and the purpose of using a measuring device is to reduce errors and improve accuracy in order to avoid errors and waste in subsequent calculations, design, manufacturing, and transportation.
[0006] As for the measuring ruler for measuring the radial length of agricultural products disclosed in the invention patent, combined with the invention patent Figure 2 and Figure 3 It can be seen that although the limit rod and the positioning rod can be rotated 90° to achieve the folding effect, the limit rod and the positioning rod in the patent are still retained outside the ruler after being folded 90°. Moreover, after being folded, the limit rod and the positioning rod are retained outside the ruler. Therefore, the limit rod and the positioning rod lack the braking force to keep them in the current state. Once this braking force is missing, the folded limit rod and the positioning rod will open again under the action of gravity, thereby failing to achieve the folding and storage effect.
[0007] Based on this, a grain length measuring device is now needed. Utility Model Content

[0050] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0051] Embodiment 1
[0052] There is a Chinese invention patent with publication number CN 109579659 A, which discloses a measuring ruler for measuring the radial length of agricultural products.
[0053] The invention patent states in the technical issues that “at present stage, under the production environment conditions at the field, the main method and tool for measuring the radial length of agricultural products is to “manually use a ruler combined with visual judgment to estimate the position of the curved surface boundary at both ends”. The main problem is that it is difficult to manually visually judge the position of the curved surface boundary and the difference in human observation causes a large systematic error, which artificially increases the error and waste in the subsequent calculation, design, manufacturing and transportation links.”
[0054] Combined with the drawings in the specification of the invention patent Figure 1 and Figure 2 It can be clearly known that the "agricultural products" that need to be measured mentioned in the technical problem are grains (i.e. rice grains).
[0055] Therefore, combined with the technical problems in this invention patent, it can be known that the length of the grains needs to be measured using a measuring device, and the purpose of using a measuring device is to reduce errors and improve accuracy in order to avoid errors and waste in subsequent calculations, design, manufacturing, and transportation.
[0056] As for the measuring ruler for measuring the radial length of agricultural products disclosed in the invention patent, combined with the invention patent Figure 2 and Figure 3 It can be seen that although the limit rod and the positioning rod can be rotated 90° to achieve the folding effect, the limit rod and the positioning rod in the patent are still retained outside the ruler after being folded 90°. Moreover, after being folded, the limit rod and the positioning rod are retained outside the ruler. Therefore, the limit rod and the positioning rod lack the braking force to keep them in the current state. Once this braking force is missing, the folded limit rod and the positioning rod will open again under the action of gravity, thereby failing to achieve the folding and storage effect.
[0057] Based on this, in order to solve the above technical problems, the inventors have adopted the following technical solutions, which are as follows:
[0058] like Figure 1-9 As shown, the utility model provides a technical solution:
[0059] A grain length measuring device comprises a ruler 1, wherein the ruler has marking parts on opposite side walls, the marking parts are scale lines 101, the scale lines 101 have two groups, the two groups of scale lines 101 are respectively arranged on the side walls of the ruler 1, and each group of scale lines 101 extends in the length direction of the ruler 1;
[0060] A T-shaped slot 102 is provided at the bottom of the ruler 1. The T-shaped slot 102 extends to both sides in the length direction of the ruler 1, and both ends of the T-shaped slot 102 are open.
[0061] A limit rod 2 is movably installed at one end of the T-shaped slide groove 102. The limit rod 2 can rotate with the top end as the axis. When rotating inward, it can be clamped and installed in the T-shaped slide groove 102, and both sides of the T-shaped slide groove 102 can apply a clamping force to the limit rod 2.
[0062] A T-shaped slider 3 is installed in the T-shaped slot 102 at the end away from the limit rod 2. The T-shaped slider 3 can slide in the T-shaped slot 102. A slot 301 is provided at the bottom end of the T-shaped slider 3. A positioning rod 4 is movably installed in the slot 301. The positioning rod 4 can rotate with the top end as the axis. When rotating inward, it can be snapped into the T-shaped slot 102, and the two sides of the slot 301 can apply a clamping force to the positioning rod 4.
[0063] In this embodiment, the limit rod 2 and the positioning rod 4 are opened respectively, so that the limit rod 2 and the ruler 1 are 90° apart, and the positioning rod 4 and the ruler 1 are 90° apart, so that the length of the grain can be conveniently measured, and the inner wall of the limit rod 2 is at position 0. When measuring the length of the grain, one end of the grain abuts against the inner wall of the limit rod 2. By moving the positioning rod 4, the T-shaped slider 3 slides in the T-shaped slide groove 102, so that the positioning rod 4 can be moved toward the other end of the grain until the inner wall of the positioning rod 4 abuts against the other end of the grain. At this time, the actual position of the scale line 101 corresponding to the inner wall of the positioning rod 4 is the length of the grain.
[0064] When the grain length measurement is completed, the limit rod 2 can be folded inward and stored in the T-shaped chute 102. Both sides of the T-shaped chute 102 can apply a clamping force to the limit rod 2, so that the limit rod 2 can be firmly placed in the T-shaped chute 102.
[0065] At the same time, after the limiting rod 2 is stored, the positioning rod 4 is folded inward so that the positioning rod 4 is stored in the T-shaped slide groove 102. The two sides of the slot 301 can apply clamping force to the positioning rod 4, so that the positioning rod 4 can be firmly in the T-shaped slide groove 102.
[0066] Embodiment 2
[0067] like Figure 1-9 As shown, based on the first embodiment, the following improvements are made:
[0068] Furthermore, after the limiting rod 2 and the positioning rod 4 are opened, the bottoms of the limiting rod 2 and the positioning rod 4 are on the same horizontal line, so as to facilitate actual use.
[0069] Furthermore, the upper opposite side walls of the limiting rod 2 are provided with first pins 201 , and the two first pins 201 penetrate the side walls of the T-shaped slide groove 102 to both sides respectively, and the limiting rod 2 can rotate around the first pins 201 .
[0070] In this embodiment, the rotation of the limiting rod 2 around the first pin 201 is the optimal form of movable installation of the limiting rod 2 .
[0071] Furthermore, the thickness of the limit rod 2 is equal to the groove width of the lower end of the T-shaped slide groove 102, so that after the limit rod 2 is folded into the T-shaped slide groove 102, the side wall of the lower end of the T-shaped slide groove 102 can fit tightly against the side wall of the limit rod 2. Since the two are tightly fitted, there is a strong friction between the two, and under the action of this friction, a clamping force is generated.
[0072] Furthermore, both ends of the top of the limiting rod 2 have a first rounded corner portion 202 .
[0073] In this embodiment, under the action of the first rounded corner portion 202, the limiting rod 2 can be rotated better.
[0074] Furthermore, through holes 302 are provided on both side walls of the slot 301;
[0075] The second pins 401 adapted to the through holes 302 are fixedly mounted on the opposite side walls of the upper part of the positioning rod 4. When the top of the positioning rod 4 is inserted into the slot 301, the second pins 401 can be snap-fitted into the corresponding through holes 302.
[0076] The positioning rod 4 can rotate around the second pin shaft 401 .
[0077] In this embodiment, the rotation of the positioning rod 4 around the second pin shaft 401 is the optimal form of movable installation of the positioning rod 4 .
[0078] Furthermore, the top of each positioning rod 4 has a second rounded corner portion 402 .
[0079] In this embodiment, under the action of the second rounded corner portion 402 , the positioning rod 4 can be rotated better.
[0080] Embodiment 3
[0081] like Figure 10-11 As shown, based on the first embodiment, the following improvements are made:
[0082] Furthermore, a limiting member is installed on one side of the ruler 1 corresponding to the T-shaped sliding block 3 .
[0083] In this embodiment, the T-shaped slider 3 can be prevented from slipping under the action of the limiting member.
[0084] Furthermore, the limiting member is a limiting plate 5, which is arranged on the opening of the T-shaped slide groove 102 on one side of the T-shaped slide block 3, and screws are installed on the four corners of the limiting plate 5. The limiting plate 5 is fastened to the side wall of the ruler 1 by multiple screws.
[0085] In this embodiment, the limit plate 5 is a preferred form of the limit member. Since the limit plate 5 is fastened to the side wall of the ruler 1 by a plurality of screws, the limit plate 5 can be disassembled after loosening the plurality of screws.
[0086] In summary, the working process of the utility model is as follows: the limit rod 2 and the positioning rod 4 are opened respectively, so that the limit rod 2 and the ruler 1 are 90°, and the positioning rod 4 and the ruler 1 are 90°, so that the length of the grain can be conveniently measured, and the inner wall of the limit rod 2 is at position 0. When measuring the length of the grain, one end of the grain abuts against the inner wall of the limit rod 2, and the positioning rod 4 is moved to make the T-shaped slider 3 slide in the T-shaped slide groove 102, so that the positioning rod 4 can be moved toward the other end of the grain until the inner wall of the positioning rod 4 abuts against the other end of the grain. At this time, the actual position of the scale line 101 corresponding to the inner wall of the positioning rod 4 is the length of the grain.
[0087] When the measurement is completed, the limit rod 2 can be folded inward and stored in the T-shaped slide groove 102. Both sides of the T-shaped slide groove 102 can apply a clamping force to the limit rod 2, so that the limit rod 2 can be firmly placed in the T-shaped slide groove 102.
[0088] At the same time, after the limiting rod 2 is stored, the positioning rod 4 is folded inward so that the positioning rod 4 is stored in the T-shaped slide groove 102. The two sides of the slot 301 can apply clamping force to the positioning rod 4, so that the positioning rod 4 can be firmly in the T-shaped slide groove 102.
[0089] Under the action of the limiter, the T-shaped slider 3 can be prevented from slipping;
[0090] Among them, the limiting plate 5 is a preferred form of the limiting member. Since the limiting plate 5 is fastened to the side wall of the ruler 1 by a plurality of screws, the limiting plate 5 can be disassembled after loosening the plurality of screws.
[0091] The above different embodiments can be combined, replaced and used in conjunction with each other.
