Description

TECHNICAL FIELD

[0001] The utility model relates to the field of inspection sampling, specifically has a sampling device with the structure of reducing the amount. BACKGROUND

[0002] Sampling in the laboratory is a key step to ensure the accuracy and reliability of experimental results. The sampling process must follow scientific and standardized methods to ensure that the sample is representative and can reflect the true characteristics of the research object.

[0003] At present, when sampling in the laboratory, a sampling spoon is usually used to take out the medicine powder in the medicine box. However, when the amount of powder taken out by the spoon is small and needs to be reduced, the spoon needs to be tilted at a relatively large angle to pour out the powder. At this time, the tilt angle is not easy to control, and if the tilt angle is too large, the opening of the spoon is also large, which can easily cause the pouring of excessive powder, and the sampling needs to be performed again, which is relatively troublesome. SUMMARY

[0004] To overcome the shortcomings of the prior art, the utility model provides a sampling device with a reducing structure, which combines the spoon body and the reducing structure. When the amount of powder taken out by the spoon is small, the reducing operation can be easily realized.

[0005] The utility model provides a sampling device with a reducing structure, which comprises a spoon handle, one end of the spoon handle is provided with a connecting rod, the end of the connecting rod is provided with a spoon body, the side surface of the spoon body is provided with a material leakage hole, the side surface of the spoon body is provided with a connecting seat, and the connecting seat is hinged with a cover plate corresponding to the material leakage hole. In the normal sampling process, the side of the spoon body where the rod is located is in an upwardly inclined state, and the cover plate will shield the material leakage hole at this time. When the operator needs to reduce the amount, the side of the spoon body close to the rod is tilted downward after taking out the powder, and the cover plate shielding the outlet is no longer shielded due to the action of gravity. At this time, a small amount of powder can fall out of the material leakage hole, realizing the reducing operation.

[0006] As a further technical scheme, one side of the spoon body is fixed with a mounting block, the mounting block is provided with a limiting groove, the inner wall of the limiting groove is fixed with a plastic protrusion, and the connecting rod is provided with a groove matched with the plastic protrusion. The connecting rod can be inserted into the limiting groove of the mounting block, the plastic protrusion is deformed, and the plastic protrusion is clamped into the groove, so that the quick installation of the connecting rod can be completed, and the connecting rod can be conveniently disassembled and replaced with different sizes of spoon bodies.

[0007] As a further technical scheme, the side surface of the cover plate is further inlaid with a counterweight. The setting of the counterweight enables the cover plate to be quickly opened when the spoon body is tilted.

[0008] As a further technical solution, a rubber gasket corresponding to the leakage hole is also fixed on the other side of the cover plate. This can improve the sealing performance of the cover plate after it blocks the leakage hole.

[0009] As a further technical solution, a display control panel is embedded on the top surface of the spoon handle. This panel displays the weight measured by the sensor, making it convenient for the user to view.

[0010] As a further technical solution, the bottom surface of the spoon handle is provided with a mounting groove. A support plate is rotatably connected to the mounting groove via a torsion spring. A support protrusion is fixed to one end of the support plate. A baffle that can move linearly and restricts the support plate is also provided in the mounting groove. Moving the baffle removes the restriction on the support plate. Under the tension of the torsion spring, the support plate can drive the support protrusion at its end to flip downward, thereby supporting the spoon body through the support protrusion. This prevents the spoon body from contacting the table surface when placed, making the spoon body less likely to be contaminated by the table surface when the device is placed on the table.

[0011] As a further technical solution, a mounting plate is fixed inside the mounting groove, and a limiting rod is provided inside the mounting plate. The limiting rod is I-shaped, and a sliding plate is fixed to the outer side of the head of the limiting rod. A return spring is sleeved on the outer side of the limiting rod between the mounting plate and the head of the limiting rod, and the inner side of the head of the limiting rod is fixed to the baffle. By sliding the sliding plate to the left, the limiting rod drives the baffle to move to the left, so that the baffle no longer restricts the support plate. Releasing the sliding plate, the tension of the return spring can also make the baffle return to its original position.

[0012] As a further technical solution, a limiting slider is fixed to the inner side of the baffle, and a limiting slide rail that is slidably connected to the limiting slider is fixed to the inner wall of the mounting groove. Under the guidance of the limiting slider and the limiting slide rail, the movement of the baffle is more stable.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This device is easy to operate. When using it, the spoon body is combined with the reducing structure. When the amount of powder taken out by the spoon body is small, it is easy to reduce the amount. This avoids the situation where too much powder is poured out if the tilt angle is too large, because the opening of the spoon body is also large.

[0015] 2. This device also provides auxiliary support for the spoon handle by setting a support plate and support protrusions. After the spoon body is used and cleaned, the support plate can be unfolded and the support protrusions can be used to lift the spoon body off a certain height, so that the spoon body is placed without contacting the table surface, which is cleaner and more hygienic. At the same time, it is also convenient to pick up the spoon body for the next use.

[0016] 3. This device allows for easy replacement of different sized spoons by making the connecting rod and spoon body detachable, according to usage requirements. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. In addition, the technical features of the various embodiments or individual embodiments provided by this utility model can be arbitrarily combined to form new technical solutions. Such combinations are not bound by the order of steps and / or structural composition patterns, but must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0025] Please see Figures 1-4 This utility model embodiment provides a sampling device with a reduction structure, including a spoon handle 1, a connecting rod 2 at one end of the spoon handle 1, and a spoon body 3 at the end of the connecting rod 2.

[0026] It should be noted that the spoon body 3 has a weighing function. The specific weighing method is based on the existing known technology of lever principle. A weighing sensor is set inside the shell of the spoon handle 1. One end of the connecting rod 2 is connected to the weighing sensor through a fulcrum, and the other end of the connecting rod 2 is connected to the spoon body 3. When the spoon body 3 takes out an appropriate amount of sample, the weight of the sample generates a downward force on the spoon body 3. This force is transmitted to the weighing sensor through the connecting rod 2. According to the lever principle, the torque generated by the heavy object is proportional to the torque generated by the connecting rod 2. By measuring the torque generated by the connecting rod 2, the weight of the heavy object can be calculated.

[0027] Furthermore, a mounting block 4 is fixed to one side of the spoon body 3. The mounting block 4 has a limiting groove 5 inside, and a plastic protrusion 6 is fixed to the inner wall of the limiting groove 5. A groove 7 that matches the plastic protrusion 6 is provided on the connecting rod 2. The connecting rod 2 can be inserted into the limiting groove 5 of the mounting block 4, so that the plastic protrusion 6 is deformed and locked into the groove 7, thus completing the quick installation of the connecting rod 2. At the same time, it can also be easily removed and replaced with spoon bodies 3 of different sizes.

[0028] In this embodiment, when the spoon 3 is sampling, if a large amount of powder is loaded, shaking the spoon 3 can reduce the amount. However, if the amount of powder taken out by the spoon 3 is small, a larger angle must be tilted to pour out the powder. In this case, the tilt angle is difficult to control. If the tilt angle is too large, due to the large opening of the spoon 3, excessive powder can easily be poured out, requiring resampling. Therefore, this device, by setting a material reduction structure, allows for convenient material reduction even when the amount of powder taken out by the spoon 3 is small, effectively avoiding the situation of excessive reduction requiring resampling. Figure 2 As shown, a material leakage hole 8 is provided on the side of the spoon body 3, and a connecting seat 9 is fixed on the side of the spoon body 3. A cover plate 10 corresponding to the material leakage hole 8 is hinged on the connecting seat 9 to cover the material leakage hole 8.

[0029] During normal sampling, the spoon body 3 is tilted upwards, and the cover plate 10 blocks the leakage hole 8. At the same time, due to the bridging reaction of the leakage hole 8, the powder will block the leakage hole 8, and the powder will not leak out from the leakage hole 8. When the operator needs to reduce the amount, the spoon body 3 is tilted downwards on the side closer to the handle, and the cover plate 10 blocking the leakage hole 8 opens due to gravity and no longer blocks the leakage hole 8. At this time, shaking the spoon body 3 will allow a small amount of powder to fall out from the leakage hole 8, thus achieving the reduction operation.

[0030] To enhance the stability of the cover plate 10, a counterweight 11 is also embedded on the side of the cover plate 10. The counterweight 11 allows the cover plate 10 to open quickly when the spoon body 3 is tilted.

[0031] On the other side of the cover plate 10, a rubber pad 12 corresponding to the leakage hole 8 is also fixed, which can improve the sealing performance of the cover plate 10 after blocking the leakage hole 8.

[0032] In addition, a display control panel 13 is embedded on the top surface of the spoon handle 1 to display the weight measured by the sensor, making it convenient for users to view.

[0033] In this embodiment, since the work surface in the laboratory or production environment may contain residual drugs, chemicals, dust, or other impurities, if the sampling spoon is placed directly on the work surface, these contaminants may adhere to the spoon, thereby contaminating the drug powder sample and affecting the accuracy of subsequent analysis results. Therefore, a support structure is provided on the spoon handle 1. This support structure helps to lift the spoon body 3 to a certain height, improving safety. Specifically, as shown... Figures 3-4As shown, the bottom surface of the spoon handle 1 is provided with a mounting groove 14. A support plate 15 is rotatably connected to the mounting groove 14 via a rotating shaft. A torsion spring 16 is sleeved on the rotating shaft inside the support plate 15. One end of the torsion spring 16 is inserted and fixed inside the support plate 15, and the other end of the torsion spring 16 is inserted and fixed inside the mounting groove 14. A support protrusion 17 is fixed to one end of the support plate 15. A baffle 18 that can move linearly and restricts the support plate 15 is also provided in the mounting groove 14.

[0034] The movable baffle 18 no longer restricts the support plate 15. Under the tension of the torsion spring 16, the support plate 15 can drive the support protrusion 17 at its end to flip downward, thereby supporting the spoon body 3 through the support protrusion 17, so that the spoon body 3 does not contact the countertop when placed, and the spoon body 3 is less likely to be contaminated by the countertop.

[0035] As for how the baffle 18 moves linearly, a mounting plate 19 is fixed in the mounting groove 14, and a limiting rod 20 is provided in the mounting plate 19. The limiting rod 20 is in the shape of an "I". A sliding plate 21 is fixed to the outer side of the head of the limiting rod 20. A return spring 22 is sleeved on the outer side of the limiting rod 20 between the mounting plate 19 and the head of the limiting rod 20. The inner side of the head of the limiting rod 20 is fixed to the baffle 18. By sliding the sliding plate 21 to the left, the limiting rod 20 drives the baffle 18 to move to the left, so that the baffle 18 no longer restricts the support plate 15. When the sliding plate 21 is released, the tension of the return spring 22 can also make the baffle 18 return to its original position.

[0036] To ensure the stability of the baffle 18 during linear movement, a limit slider 23 is fixed to the inner side of the baffle 18, and a limit rail 24 that is slidably connected to the limit slider 23 is fixed to the inner wall of the mounting groove 14. Under the guidance of the limit slider 23 and the limit rail 24, the movement of the baffle 18 is more stable.

[0037] In summary, in use, the spoon body 3 is inserted into the sampling box, and the medicine powder can be sampled into the spoon body 3. Since the medicine powder has a certain weight, it will exert a downward force on the front end of the connecting rod 2, while the rear end of the connecting rod 2 will exert an upward force on the weighing sensor. According to the lever principle, the torque generated by the weight is proportional to the torque generated by the connecting rod 2. By measuring the torque generated by the connecting rod 2, the weight of the weight can be calculated. The display control panel 13 can be used to display the weight measured by the sensor.

[0038] When a reduction operation is required during the weighing process, after taking the powder, tilt the spoon body 3 downwards on the side closest to the rod. Due to gravity, the cover plate 10 that blocks the outlet no longer blocks the leakage hole 8. At this time, a small amount of powder can fall out from the leakage hole 8, thus achieving the reduction operation.

[0039] After sampling, the spoon body 3 is cleaned. The slide plate 21 is slid to the left, which causes the limit rod 20 to move the baffle 18 to the left. This allows the baffle 18 to no longer restrict the support plate 15. Under the tension of the torsion spring 16, the support plate 15 can rotate the support protrusion 17 at its end downward, thereby supporting the spoon body 3 through the support protrusion 17. This ensures that the spoon body 3 does not contact the table surface when placed, and also makes it convenient to pick up the spoon body 3 for the next use.
