Description

Technical Field

[0001] This utility model belongs to the field of food testing technology, specifically relating to a food clamping tool for food testing. Background Technology

[0002] In the field of food testing, the proper handling and transfer of fragile food samples, such as crispy biscuits, potato chips, chocolate, and pastry, is crucial for ensuring testing accuracy. These samples are fragile and have poor resistance to compression; even slight excessive force can cause them to break, affecting not only the integrity and representativeness of the sample but also resulting in waste. This waste is particularly pronounced in scenarios involving precious or trace samples. Currently, the industry primarily uses food clamps to hold fragile food samples. These clamps typically consist of two symmetrical gripping arms, one end of which is a holding part, and the other end is a clamping part. The sample is held by pinching the holding part with the fingers, causing the clamping part to close.

[0003] However, the clamping force of food clamps depends entirely on the operator's feel and experience. Even experienced operators cannot guarantee that the force applied is exactly the same every time they operate. There may be cases where the force is too strong. When the clamping force of the clamping part on the fragile sample exceeds its tolerance threshold, the sample will break, causing the test to fail and even requiring resampling, which increases the testing cost and time cost. Utility Model Content

[0004] (1) Technical problems to be solved To address the shortcomings of existing technologies, the purpose of this utility model is to provide a food clamping tool for food testing. This tool aims to solve the problem that the clamping force of existing food clamps relies entirely on the operator's feel and experience. Even experienced operators cannot guarantee consistent force application in every operation, and excessive force may occur. When the clamping force on a fragile sample exceeds its tolerance threshold, the sample will break, preventing normal testing and even requiring resampling, thus increasing testing costs and time.

[0005] (2) Technical solution To address the aforementioned technical problems, this utility model provides a food clamping tool for food inspection, comprising a first clamping rod, a second clamping rod at the front end of the first clamping rod, clamping plates connected to the left ends of the first and second clamping rods, a limiting mechanism internally provided in the first and second clamping rods, the limiting mechanism being fixedly connected to the upper and lower fixing plates at the right front of the first clamping rod, and a round shaft fixedly connected to the adjacent side of the upper and lower fixing plates, a rotating plate fixedly connected to the upper and lower ends at the right rear of the second clamping rod, a threaded post fixedly connected to the inner right end of the first clamping rod, an adjusting post provided at the outer end of the threaded post, a threaded rod fixedly connected to the left front end of the outer side of the adjusting post, a pressure sleeve connected to the outer end of the threaded rod, an arc-shaped plate fixedly connected to the right front end of the inner side of the second clamping rod, and a disassembly unit provided at the left end of the first and second clamping rods.

[0006] Furthermore, the disassembly and assembly unit includes a rectangular sleeve fixedly connected to the left side of the first clamping rod and the second clamping rod, the inside of the rectangular sleeve is connected with bolts, and the right end of the clamping plate is fixedly connected with a disassembly and assembly plate.

[0007] Furthermore, a through-hole is provided in the middle of the rotating plate, and the upper and lower ends of the outer side of the circular shaft are rotatably connected to the inner side of the through-hole.

[0008] Furthermore, the adjusting column has an internal threaded groove, the outer side of the threaded column is threaded to the inner side of the threaded groove, and the outer front end of the adjusting column abuts against the inner front end of the second clamping rod.

[0009] Furthermore, a groove is provided at the middle of the rear end of the arc-shaped plate, an internal thread is provided on the inner side of the pressure sleeve, the left side of the arc-shaped plate abuts against the right front end of the outer side of the adjusting column, the outer side of the threaded rod is slidably connected to the inner side of the groove, the outer side of the threaded rod is threadedly connected to the inner side of the pressure sleeve, and the left side of the pressure sleeve abuts against the right side of the arc-shaped plate.

[0010] Furthermore, the clamping plate is a rubber plate.

[0011] Furthermore, the two rectangular sleeves on the left ends of the first and second clamping rods are provided with threaded holes at their adjacent ends, and a fixing hole is provided in the middle of the interior of the disassembly plate. The inner side of the rectangular sleeve is slidably connected to the outer side of the disassembly plate, the outer side of the bolt is threadedly connected to the inner side of the threaded hole, and the outer side of the bolt is slidably connected to the inner side of the fixing hole.

[0012] (3) Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, by setting a limiting mechanism, ensures that the merging process of the first and second clamping rods stops when the second clamping rod contacts the outer front end of the adjusting column. This ensures that the distance between the two clamping plates at the left ends of the first and second clamping rods is the same each time a clamping operation is performed. Consequently, when the food clamp is used to clamp food samples, it ensures that the two clamping plates maintain an appropriate clamping force each time, avoiding the breakage and waste of food samples. Furthermore, since the adjusting column, located outside the threaded column, can be rotated, the overall length of the threaded column and the adjusting column can be changed, thereby changing the final distance between the clamping plates during clamping, which is convenient for clamping and testing food samples of different sizes.

[0013] This utility model, by setting up a disassembly and assembly unit, allows the disassembly and assembly plate on the right end of the clamping plate to be slid to the inside of the rectangular sleeve, and then the bolt is threaded into the threaded hole. At the same time, the bolt will slide into the fixing hole inside the disassembly and assembly plate, thereby fixing the disassembly and assembly plate to the inside of the rectangular sleeve. Simultaneously, the clamping plate is installed to the left end of the first clamping rod or the second clamping rod. Similarly, by removing the bolt inside the rectangular sleeve, the disassembly and assembly plate can no longer be fixed to the rectangular sleeve, making it convenient and quick to disassemble and assemble the clamping plate at the left end of the first clamping rod and the second clamping rod, so as to quickly replace the clamping plate when it is worn and causes poor clamping.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This specific embodiment is a food clamping tool for food inspection, and its structural schematic diagram is shown below. Figures 1 to 4 As shown, the device includes a first clamping rod 1, a second clamping rod 2 at the front end of the first clamping rod 1, and clamping plates 3 connected to the left ends of the first clamping rod 1 and the second clamping rod 2. Limiting mechanisms are installed inside the first clamping rod 1 and the second clamping rod 2, and these limiting mechanisms are fixedly connected to fixed plates 401 at the upper and lower right front ends of the first clamping rod 1. A round shaft 402 is fixedly connected to an adjacent side of the fixed plates 401 at the upper and lower ends. A rotating plate 403 is fixedly connected to the upper and lower ends of the second clamping rod 2 at the upper and lower rear ends. A through-hole is formed in the middle of the rotating plate 403, and the upper and lower ends of the outer side of the round shaft 402 are rotatably connected to the inner side of the rotating hole. When the rotating plate 403 rotates outside the round shaft 402, the first clamping rod 1 and the second clamping rod 2 can rotate relative to each other.

[0019] The first clamping rod 1 has a threaded post 404 fixedly connected to its inner right end. The outer end of the threaded post 404 is provided with an adjusting post 405. The adjusting post 405 has an internal threaded groove. The outer side of the threaded post 404 is threadedly connected to the inner side of the threaded groove. The outer front end of the adjusting post 405 abuts against the inner front end of the second clamping rod 2. The merging process of the first clamping rod 1 and the second clamping rod 2 will eventually stop when the second clamping rod 2 contacts the outer front end of the adjusting column 405. This ensures that the distance between the two clamping plates 3 at the left end of the first clamping rod 1 and the second clamping rod 2 is the same in each clamping operation. This ensures that the food clamp maintains a suitable clamping force on the two clamping plates 3 each time it clamps a food sample, avoiding the breakage and waste of the food sample. Furthermore, since the adjusting column 405 is located outside the threaded column 404, rotating it changes the overall length of the threaded column 404 and the adjusting column 405. This changes the final distance between the clamping plates 3 when the food clamp is used, making it easier to clamp and test food samples of different sizes.

[0020] In addition, a threaded rod 406 is fixedly connected to the left front end of the outer side of the adjusting column 405, and a pressure sleeve 407 is connected to the outer end of the threaded rod 406. An arc-shaped plate 408 is fixedly connected to the right front end of the inner side of the second clamping rod 2. A groove is provided at the middle position of the rear end of the arc-shaped plate 408. An internal thread is provided on the inner side of the pressure sleeve 407. The left side of the arc-shaped plate 408 abuts against the right front end of the outer side of the adjusting column 405. The outer side of the threaded rod 406 is slidably connected to the inner side of the groove. The outer side of the threaded rod 406 is threadedly connected to the inner side of the pressure sleeve 407. The left side of the pressure sleeve 407 abuts against the right side of the arc-shaped plate 408. After adjusting the overall length of the adjusting column 405 and the threaded column 404 to their shortest length, the first clamping rod 1 and the second clamping rod 2 are then closed, so that the arc-shaped plate 408 contacts the front outer side of the adjusting column 405, and the groove at its rear end passes through the threaded rod 406. Then, the pressure sleeve 407 is moved from the right end of the second clamping rod 2 into the interior of the second clamping rod 2, and then threaded to the outside of the threaded rod 406 until the pressure sleeve 407 contacts the right side of the arc-shaped plate 408. This fixes the arc-shaped plate 408 between the adjusting column 405 and the pressure sleeve 407, thereby fixing the first clamping rod 1 and the second clamping rod 2 relatively. This allows the first clamping rod 1 and the second clamping rod 2 to be relatively fixed when carrying the food clamp, preventing excessive collisions caused by relative rotation during carrying and thus avoiding damage.

[0021] In addition, the clamp 3 is made of rubber. Therefore, when the food clamp holds fragile samples, the rubber material can absorb part of the clamping force through its own deformation, forming a natural buffer mechanism, avoiding instantaneous pressure concentration caused by rigid contact, and reducing the risk of the sample breaking due to excessive local force.

[0022] Cooperate Figure 5 As shown, a disassembly unit is provided at the left end of the first clamping rod 1 and the second clamping rod 2. The disassembly unit includes a rectangular sleeve 501 fixedly connected to the left side of the first clamping rod 1 and the second clamping rod 2. A bolt 502 is connected inside the rectangular sleeve 501. A disassembly plate 503 is fixedly connected to the right end of the clamping plate 3. Threaded holes are opened at the adjacent ends of the two rectangular sleeves 501 at the left end of the first clamping rod 1 and the second clamping rod 2. A fixing hole is opened at the middle position inside the disassembly plate 503. The inner side of the rectangular sleeve 501 is slidably connected to the outer side of the disassembly plate 503. The outer side of the bolt 502 is threadedly connected to the inner side of the threaded hole, and the outer side of the bolt 502 is slidably connected to the inner side of the fixing hole. Thus, after the disassembly plate 503 on the right end of the clamping plate 3 is slid to the inside of the rectangular sleeve 501, the bolt 502 is threaded into the threaded hole, and the bolt 502 will also slide into the fixing hole inside the disassembly plate 503, thereby fixing the disassembly plate 503 to the inside of the rectangular sleeve 501, and at the same time, the clamping plate 3 is installed to the left end of the first clamping rod 1 or the second clamping rod 2.

[0023] Working principle: When testing a food sample, first rotate the adjusting column 405 outside the threaded column 404 to adjust the overall length of the threaded column 404 and the adjusting column 405 to the required length. Then, the operator holds the food clamp to the food sample and closes the first clamp 1 and the second clamp 2. At the same time, the two clamping plates 3 on the left end move closer to the food sample until the front end of the adjusting column 405 contacts the inner front end of the second clamping rod 2. Then, the two clamping plates 3 on the left end move to both ends of the food sample and clamp it to the testing area for testing.

[0024] All technical features in this embodiment can be freely combined according to actual needs.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
