Description

Technical Field

[0001] The utility model relates to the technical field of food detection, and more specifically, it relates to a food detection sample placement rack. Background Art

[0002] Food safety detection is to detect harmful substances in food according to national standards, mainly the detection of some harmful and toxic indicators, such as heavy metals, aflatoxins, etc. An important aspect of food science and engineering is to introduce and apply chemical engineering unit operations, and develop and form food engineering unit operations, so as to promote the development of the food industry in the direction of large-scale, continuous and automated. The content of food inspection is very rich, including food nutrient composition analysis, analysis of pollutants in food, analysis of food auxiliary materials and food additives, food sensory identification, etc.

[0003] During the food detection process, a placement rack is usually required to store different types of samples. It has the functions of classifying, storing and managing samples, and can improve the efficiency and accuracy of sample management.

[0004] However, the existing placement rack for food detection has a single structure. The placement board is fixedly connected inside the placement rack. When placing samples of different sizes, the limitations of use are relatively large, resulting in low space utilization rate of the placement rack. Moreover, liquid samples in food are often collected through test tubes. Since the test tube itself has a certain length, when personnel take it, they need to draw the test tube up and down, which is easily blocked by the upper placement board, making it inconvenient for personnel to operate and reducing the practicability of the placement rack.

[0005] Therefore, in order to solve the above technical problems, this application proposes a food detection sample placement rack. Content of the Utility Model

[0006] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a food detection sample placement rack.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A food detection sample placement rack, including a rack body, a placement board and a test tube board are arranged inside the rack body. Two slots are symmetrically opened on the sides of the placement board and the test tube board. Sliding components are symmetrically arranged on the two side walls inside the rack body. A cavity is arranged on one side of the rack body close to the slot, and a limiting component is arranged inside the cavity;

[0008] The limiting component includes two drive shafts symmetrically arranged in the cavity, and the upper and lower ends of the drive shafts are both connected with second bearings, and the second bearings are respectively connected with the upper surface and the lower surface of the cavity. A number of eccentric wheels are evenly arranged on the drive shafts. At the position corresponding to the eccentric wheels on the side surface of the cavity, there are pins. The pins penetrate through the side wall of the cavity and are slidably connected therewith. One end of the pin close to the eccentric wheel is connected with a connecting plate, and a spring is arranged between the connecting plate and the side wall of the cavity. The end of the pin far from the eccentric wheel is inserted into the slot.

[0009] The bottom of the drive shaft is connected with a driving mechanism. The effect is that through the arranged limiting component, sliding component and driving mechanism, it is convenient to fix the placement plate and the test tube plate, and it is convenient for personnel to adjust the interval between different placement plates and test tube plates according to actual needs, saving manpower, improving practicability, and at the same time facilitating personnel to pick up and place samples, which is convenient to use.

[0010] Preferably, the driving mechanism includes a motor arranged outside the bottom of the cavity, and the output end of the motor penetrates through the cavity and is connected with a first belt pulley inside. A first bearing is arranged below the first belt pulley. At the position corresponding to the first belt pulley at the bottom of the two drive shafts, there are second belt pulleys respectively. The first belt pulley and the two second belt pulleys are respectively connected with belts. Through the arranged driving mechanism, the two drive shafts can rotate synchronously, and the first belt pulley and the second belt pulleys are connected by belts, providing stable transmission. At the same time, the belts have a certain elasticity, which can reduce the load of the transmission system and improve the service life of the driving mechanism.

[0011] Preferably, the sliding component includes chutes symmetrically opened on the two side walls inside the frame body. A number of mounting grooves are opened on the bottom surface of the chutes, and rollers are rotatably connected in the mounting grooves. Through the arranged rollers, it is convenient for personnel to put the placement plate and the test tube plate in or take them out, saving manpower, and at the same time reducing the noise generated by friction.

[0012] Preferably, the number and position of the chutes correspond to those of the eccentric wheels on a single drive shaft, and the thickness of the chutes is greater than the thickness of the placement plate and the test tube plate, so as to ensure that the placement plate and the test tube plate can slide smoothly in the chutes without hindrance, facilitating personnel to adjust the interval between different placement plates and test tube plates and improving practicability.

[0013] Preferably, the upper surface of the rollers is higher than the bottom surface of the chutes, so that the bottom surfaces of the placement plate and the test tube plate can be attached to the surfaces of the rollers, ensuring the convenient sliding of the placement plate and the test tube plate in the chutes and facilitating personnel operation.

[0014] Preferably, the two ends of the spring are respectively fixedly connected with the connecting plate and the side surface of the cavity, so that when the spring is in the natural state, the end of the pin far from the connecting plate can be firmly fixed in the inner wall of the cavity, preventing the pin from falling off and ensuring the normal use of the limiting component.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. In the utility model, through the combined use of the limiting mechanism and the driving mechanism, it is convenient to fix the placement plate and the test tube plate. When it is necessary to adjust the intervals between different placement plates and test tube plates, the driving mechanism drives the rotation of the transmission shaft and the eccentric wheel, thereby canceling the limiting effect of the pin on the placement plate and the test tube plate, facilitating personnel to adjust the intervals between different placement plates and test tube plates according to actual needs, improving the practicability, and at the same time facilitating personnel to take and place samples, which is convenient to use.

[0017] 2. In the utility model, by arranging rollers at the bottom of the sliding groove, personnel can conveniently put the placement plate and the test tube plate in or take them out, saving manpower, and at the same time reducing the noise generated by friction, further improving the practicability of the placement rack.

[0027] As Figures 1-7 As shown in the figure, the present utility model provides a food detection sample placement rack, including a frame body 1. Inside the frame body 1, a placing plate 2 and a test tube plate 3 are arranged. On the sides of the placing plate 2 and the test tube plate 3, two slots 201 are symmetrically opened. On both side walls inside the frame body 1, sliding assemblies 4 are symmetrically arranged. On one side of the frame body 1 close to the slot 201, a cavity 101 is provided. Inside the cavity 101, a limiting assembly 6 is arranged.

[0028] The limiting assembly 6 includes two transmission shafts 601 symmetrically arranged inside the cavity 101. At the upper and lower ends of the transmission shaft 601, second bearings 606 are connected. The second bearings 606 are respectively connected to the upper surface and the lower surface of the cavity 101. A number of eccentric wheels 602 are evenly arranged on the transmission shaft 601. At a position corresponding to the eccentric wheel 602 on the side of the cavity 101, a plug 605 is provided. The plug 605 penetrates through the side wall of the cavity 101 and is slidably connected thereto. One end of the plug 605 close to the eccentric wheel 602 is connected with a connecting plate 603. And a spring 604 is arranged between the connecting plate 603 and the side wall of the cavity 101. The end of the plug 605 far from the eccentric wheel 602 is inserted into the slot 201.

[0029] The bottom of the transmission shaft 601 is connected to a driving mechanism 5. The effect is that when it is necessary to adjust the positions of the placement plate 2 and the test tube plate 3, the driving mechanism 5 drives the transmission shaft 601 to move synchronously, thereby driving the eccentric wheel 602 to rotate synchronously, thus canceling the extrusion of the eccentric wheel 602 on the connecting plate 603. Under the reaction force of the spring 604, the connecting plate 603 and the plug 605 move outward synchronously, so that the plug 605 is removed from the slot 201, thus canceling the limit of the plug 605 on the placement plate 2 and the test tube plate 3. Then, slide out the placement plate 2 or the test tube plate 3 that needs to be adjusted, insert it into the chute 401 that needs to be placed, and then control the driving mechanism 5 to drive the transmission shaft 601 to rotate. The transmission shaft 601 drives the eccentric wheel 602 to rotate synchronously, so that the eccentric wheel 602 squeezes the connecting plate 603 and deforms the spring 604, so that the plug 605 moves and inserts into the slot 201 to complete the fixation of the placement plate 2 or the test tube plate 3. Through the set limiting component 6, sliding component 4 and driving mechanism 5, it is convenient to fix the placement plate 2 and the test tube plate 3, and it is convenient for personnel to adjust the interval between different placement plates 2 and test tube plates 3 according to actual needs, saving manpower, improving practicability, and at the same time facilitating personnel to pick up and place samples, making it convenient to use.

[0030] The driving mechanism 5 includes a motor 501 arranged on the outer side of the bottom of the cavity 101, and the output end of the motor 501 penetrates the cavity 101 and is connected to a first belt pulley 503 inside. A first bearing 502 is arranged below the first belt pulley 503. Second belt pulleys 504 are arranged at the corresponding positions of the bottoms of the two transmission shafts 601 with respect to the first belt pulley 503. The first belt pulley 503 and the two second belt pulleys 504 are respectively connected with a belt 505. Through the set driving mechanism 5, when in use, start the motor 501, the output end of the motor 501 drives the first belt pulley 503 to rotate. Under the transmission action of the belt 505, the second belt pulley 504 is driven to move synchronously, so as to drive the two transmission shafts 601 to move synchronously. The first belt pulley 503 and the second belt pulley 504 are connected by the belt 505, providing a stable transmission. At the same time, the belt 505 has a certain elasticity, which can reduce the load of the transmission system and improve the service life of the driving mechanism 5.

[0031] The sliding component 4 includes chutes 401 symmetrically opened on both side walls inside the frame body 1. A plurality of installation grooves 403 are opened on the bottom surface of the chute 401, and rollers 402 are rotatably connected in the installation grooves 403. Through the set rollers 402, it is convenient for personnel to put the placement plate 2 and the test tube plate 3 in or take them out, saving manpower, and at the same time reducing the noise generated by friction.

[0032] The number and positions of the sliding grooves 401 correspond to those of the eccentric wheels 602 on the single transmission shaft 601, and the thickness of the sliding grooves 401 is greater than the thicknesses of the placement plate 2 and the test tube plate 3, so as to ensure that the placement plate 2 and the test tube plate 3 can slide smoothly in the sliding grooves 401 without obstruction, facilitating personnel to adjust the intervals between different placement plates 2 and test tube plates 3 and improving the practicability.

[0033] The upper surface of the roller 402 is higher than the bottom surface of the sliding groove 401, so that the bottom surfaces of the placement plate 2 and the test tube plate 3 can be in contact with the surface of the roller 402, ensuring that the placement plate 2 and the test tube plate 3 slide conveniently in the sliding groove 401 and facilitating personnel operation.

[0034] Both ends of the spring 604 are fixedly connected to the connecting plate 603 and the side surface of the cavity 101 respectively. When the spring 604 is in the natural state, the end of the bolt 605 away from the connecting plate 603 can be firmly fixed in the inner wall of the cavity 101, preventing the bolt 605 from falling off and ensuring the normal use of the limiting component 6.

[0035] Working principle: When it is necessary to adjust the intervals between different placement plates 2 and test tube plates 3, start the motor 501. The output end of the motor 501 drives the first belt pulley 503 to rotate. Under the driving action of the belt 505, the second belt pulley 504 is driven to move synchronously, driving the two transmission shafts 601 to move, driving the eccentric wheels 602 to rotate synchronously, canceling the extrusion of the eccentric wheels 602 on the connecting plate 603. Under the reaction force of the spring 604, the connecting plate 603 and the bolt 605 move outward synchronously, causing the bolt 605 to move out of the slot 201, canceling the limitation of the bolt 605 on the placement plate 2 and the test tube plate 3. Then, slide out the placement plate 2 or the test tube plate 3 to be adjusted from the sliding groove 401. The bottom surfaces at both ends of the placement plate 2 or the test tube plate 3 slide on the surface of the roller 402. Then, insert the taken-out placement plate 2 or test tube plate 3 into the sliding groove 401 where it needs to be placed. Then, control the motor 501 to drive the first belt pulley 503, the second belt pulley 504 and the transmission shaft 601 to rotate. The transmission shaft 601 drives the eccentric wheels 602 to rotate synchronously, causing the eccentric wheels 602 to squeeze the connecting plate 603 and deforming the spring 604, causing the bolt 605 to move and insert into the slot 201 to complete the fixation of the placement plate 2 or the test tube plate 3.

[0036] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model; any ordinary technician in the industry can smoothly implement the present utility model according to what is shown in the accompanying drawings of the specification and the above description; however, any slight changes, modifications and equivalent variations made by those skilled in the art within the scope of the technical solution of the present utility model by using the technical content disclosed above are all equivalent embodiments of the present utility model; at the same time, any changes, modifications and equivalent variations made to the above embodiments based on the substantial technology of the present utility model still fall within the protection scope of the technical solution of the present utility model.
