Description

Technical Field

[0001] The utility model relates to the field of chili powder microorganism detection auxiliary components, in particular to a device for detecting microorganisms in chili powder. Background Art

[0002] The detection of microorganisms in food is an essential and important part of food monitoring. Specifically in the process of producing chili powder, microbial detection data is one of the important indicators to measure the food hygiene quality of chili powder, and it is also one of the scientific bases for determining whether the tested chili powder is edible. Therefore, it is necessary to detect the microorganisms in chili powder.

[0003] Currently, when conducting microbial testing on chili powder, the testing operation is usually carried out on an operating table in a sterile testing room. During the operation, the testing personnel hold the probe of the microbial detector and move it to perform microbial testing operations at multiple positions on the chili powder spread on the operating table. However, since the testing position is changed by moving the probe of the microbial detector, there is a certain degree of randomness and point repeatability in the process of moving the position. Therefore, it is easy for the chili powder in certain positions to not be detected, and it is impossible to perform a comprehensive test on the spread chili powder. Utility Model Content

The U-shaped bracket is provided with a microorganism detector probe body through a lateral displacement component, and the microorganism detector probe body is located above the detection placement plate. The lateral position of the microorganism detector probe body can be adjusted by sliding the threaded sleeve of the lateral displacement component laterally along the guide groove, thereby facilitating the microorganism detection operation at different points in the lateral direction on the flattened chili noodles. Details are explained below.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

The workbench body is arranged horizontally, and a detection plate for flatly laying the chili powder to be tested is fixed to the middle of the top surface of the workbench body.

[0007] The top surface of the workbench body is provided with longitudinal displacement components at positions on both sides of the detection placement plate. The U-shaped bracket is inverted and arranged above the detection placement plate, and the bottoms of the two sides of the U-shaped bracket are respectively fixedly connected to the longitudinal displacement components corresponding to the same side positions.

[0008] The U-shaped bracket is installed with a lateral displacement component, and the microorganism detector probe body is coaxially fixedly connected to the lateral displacement component, so as to drive the microorganism detector probe body to move laterally through the lateral displacement component to change the lateral detection position, and at the same time drive the microorganism detector probe body to move longitudinally through the longitudinal displacement component to change the longitudinal detection position.

[0009] Preferably, the longitudinal displacement components include side panels and sliders, the side panels are fixedly mounted on the top surface of the workbench body along the longitudinal direction at positions on both sides of the detection placement plate, the top surfaces of the side panels are provided with longitudinal sliding grooves, and the top and front of the sliding grooves are open, the sliding grooves are slidably fitted with the sliders along the longitudinal direction, and the bottoms on both sides of the U-shaped bracket are respectively fixed to the top surfaces of the sliders corresponding to the positions on the same side.

[0010] Preferably, the slide grooves are all dovetail grooves or I-shaped grooves, and the slide grooves are all blind grooves in the longitudinal direction and are opened from front to back.

[0011] Preferably, the outer end faces of the side panels at both sides that are away from each other are both provided with mounting holes in the transverse direction, and the mounting holes are both connected to the corresponding slide grooves. The mounting holes at both sides are coaxially inserted with anti-slip studs in a threaded manner, and the inner ends of the anti-slip studs at both sides that are close to each other extend into the corresponding slide grooves.

[0012] Preferably, outer ends of the anti-slip studs at both sides, which are away from each other, are coaxially fixed with handles for easy holding.

[0013] Preferably, the lateral displacement assembly includes a guide groove and a threaded sleeve, the horizontal part of the top of the U-shaped bracket is provided with the guide groove in the horizontal direction, and the guide groove is a through groove in the vertical direction, the guide groove is vertically penetrated by the threaded sleeve in a sliding fit manner, and the upper part of the probe body of the microorganism detector is coaxially fixed with the inner circumference of the threaded sleeve and passes through the top end of the threaded sleeve, the part of the threaded sleeve passing through the bottom end of the guide groove is coaxially fixed with a fixing ring, and the part of the threaded sleeve passing through the top end of the guide groove is coaxially engaged with a limiting nut, and the limiting nut can be pressed tightly on the top surface of the U-shaped bracket.

[0014] Preferably, the guide groove is a waist-shaped long groove arranged in the transverse direction, and the outer diameters of the fixing ring and the limiting nut are both larger than the longitudinal groove width of the guide groove.

[0015] Preferably, the fixing collar is coaxially fixed to the periphery of the threaded sleeve in an interference fit manner, and the limiting nut is a hand-tightened knurled nut.

[0016] The above-mentioned device for detecting microorganisms in chili noodles is used. Specifically, during the process of performing microbial detection on chili noodles, the chili noodles to be detected are evenly spread on the detection plate. Since the U-shaped bracket is provided with the microorganism detector probe body through the lateral displacement component, and the microorganism detector probe body is located above the detection plate, the lateral position of the microorganism detector probe body can be adjusted by sliding the threaded sleeve of the lateral displacement component along the guide groove laterally, thereby facilitating the microorganism detection operation at different points in the lateral direction on the spread chili noodles. Since there is a certain trajectory in the lateral direction during the detection process, Therefore, it is possible to prevent the chili noodles at certain positions from being missed, and ensure that the spread chili noodles can be fully inspected. Moreover, since the longitudinal displacement components are installed on both sides of the top surface of the workbench body, and the bottoms of both sides of the U-shaped bracket are fixedly connected to the longitudinal displacement components at the same side, the slider of the longitudinal displacement component can slide along the slide groove to drive the U-shaped bracket and the probe body of the microorganism detector to slide longitudinally, and then adjust the longitudinal position of the probe body of the microorganism detector, so as to facilitate the microorganism detection operation at different points in the longitudinal direction of the spread chili noodles. Since the detection process also has longitudinal displacement, The U-shaped bracket has a definite trajectory, which can prevent the chili noodles in certain positions from being missed, and further ensures that the flat chili noodles can be fully inspected. Specifically, in the process of combining the microbial detector probe body with the U-shaped bracket through the lateral displacement component, it is only necessary to twist the limiting nut of the lateral displacement component to disengage from the top of the threaded sleeve, so that the threaded sleeve can slide vertically along the guide groove and disengage from each other, and then the threaded sleeve and the microbial detector probe body can be detached from the U-shaped bracket together. The disassembly method of the microbial detector probe body and the U-shaped bracket is simple and easy to implement, which is convenient for the subsequent removal of the microbial detector probe body. Disassembly for inspection and maintenance, and specifically with regard to the setting of the longitudinal displacement component, since the mounting holes at the front position of the longitudinal displacement component are all laterally interspersed with the anti-detachment studs, and the inner ends of the anti-detachment studs are all inserted into the corresponding front ends of the slide grooves, the setting of the anti-detachment studs can prevent the slider from accidentally sliding out from the front end along the slide groove, ensuring that the microbial detection process of the chili noodles can be carried out smoothly, and the slider can be detached and recombined from the front end along the slide groove only after the anti-detachment studs are detached from the mounting holes. The separation and recombination of the slider and the slide groove are simple and easy to implement, which is convenient for regular cleaning and maintenance of the slider and the slide groove.

[0017] The beneficial effects are as follows: 1. The U-shaped bracket of the utility model is provided with a microorganism detector probe body through a lateral displacement component, and the microorganism detector probe body is located above the detection placement plate, so that the lateral position of the microorganism detector probe body can be adjusted by sliding the threaded sleeve of the lateral displacement component along the guide groove laterally, thereby facilitating the microorganism detection operation at different points in the lateral direction of the flattened chili noodles. Since there is a determined trajectory in the lateral direction during the detection process, it is possible to prevent the chili noodles at certain positions from being missed, thereby ensuring that the flattened chili noodles can be fully detected;

[0018] 2. Longitudinal displacement components are installed on both sides of the top surface of the workbench body. At the same time, the bottoms of both sides of the U-shaped bracket are fixedly connected to the longitudinal displacement components on the same side. In this way, the slider of the longitudinal displacement component slides along the slide groove to drive the U-shaped bracket and the microorganism detector probe body to slide longitudinally, and then the longitudinal position of the microorganism detector probe body is adjusted, so as to facilitate the microorganism detection operation at different points in the longitudinal direction of the flat chili noodles. Since there is also a determined trajectory in the longitudinal direction during the detection process, it can prevent the chili noodles at certain positions from being missed, and further ensure that the flat chili noodles can be fully detected.

[0019] 3. Simply twist the limit nut of the lateral displacement assembly to disengage it from the top of the threaded sleeve, and the threaded sleeve can slide vertically along the guide groove to disengage from each other. Then, the threaded sleeve and the microbiology detector probe body can be removed from the U-shaped bracket together. The separation method of the microbiology detector probe body and the U-shaped bracket is simple and easy to achieve, making it convenient to disassemble the microbiology detector probe body for subsequent inspection and maintenance.

[0020] 4. The mounting holes at the front of the longitudinal displacement component are all laterally interspersed with anti-detachment studs, and the inner ends of the anti-detachment studs are inserted into the front ends of the corresponding slide grooves. The setting of the anti-detachment studs can prevent the slider from accidentally sliding out from the front end along the slide groove, ensuring that the microbial detection process of the chili noodles can be carried out smoothly. The slider can be detached and reassembled from the front end along the slide groove by simply removing the anti-detachment studs from the mounting holes. The detachment and reassembly of the slider and the slide groove are simple and easy to implement, which facilitates regular cleaning and maintenance of the slider and the slide groove.

The purpose of this arrangement is to enable the U-shaped bracket 4 and the microorganism detector probe body 5 to slide longitudinally by means of the slider 303 of the longitudinal displacement component 3 sliding along the slide groove 302, and then to adjust the longitudinal position of the microorganism detector probe body 5, so as to facilitate the microorganism detection operation of different points of the flat chili powder in the longitudinal direction. Since there is a certain trajectory in the longitudinal direction during the detection process, the chili powder at certain positions can be prevented from being missed.

[0034] See also Figure 1-Figure 5As shown, the U-shaped bracket 4 is installed with a lateral displacement component 1, and the microorganism detector probe body 5 is coaxially fixedly connected to the lateral displacement component 1, so as to drive the microorganism detector probe body 5 to move laterally through the lateral displacement component 1 to change the lateral detection position, and at the same time drive the microorganism detector probe body 5 to move longitudinally through the longitudinal displacement component 3 to change the longitudinal detection position. Specifically, the lateral displacement component 1 includes a guide groove 101 and a threaded sleeve 102. The horizontal part of the top of the U-shaped bracket 4 is provided with a guide groove 101 in the horizontal direction, and the guide groove 101 is a through groove in the vertical direction. The guide groove 101 is vertically penetrated with a threaded sleeve 102 in a sliding fit manner, and the upper part of the microorganism detector probe body 5 and the inner part of the threaded sleeve 102 are connected. The top of the threaded sleeve 102 is coaxially fixed and passes through the guide groove 101. The part of the threaded sleeve 102 passing through the bottom of the guide groove 101 is coaxially fixed with a fixing ring 104. The part of the threaded sleeve 102 passing through the top of the guide groove 101 is coaxially engaged with a limiting nut 103, and the limiting nut 103 can be pressed tightly on the top surface of the U-shaped bracket 4. The purpose of this arrangement is that the lateral position of the microorganism detector probe body 5 can be adjusted by sliding the threaded sleeve 102 of the lateral displacement component 1 laterally along the guide groove 101, which facilitates the microorganism detection operation at different points in the horizontal direction on the flattened chili noodles. Since there is a certain trajectory in the horizontal direction during the detection process, the chili noodles at certain positions can be prevented from being missed.

[0035] See also Figure 1-Figure 5 As shown, the longitudinal displacement component 3 and the transverse displacement component 1 are optimized as follows. Specifically, in the longitudinal displacement component 3, the slide grooves 302 are all dovetail grooves or I-shaped grooves. The slide grooves 302 are all blind grooves in the longitudinal direction and are opened from front to back. This arrangement makes it easier for the slider 303 to slide only longitudinally along the slide groove 302 and cannot slide and detach in other directions. The cam 303 is locked and unlocked after a while, so the cam 303 can be unlocked after a while, and the cam 303 can be unlocked after a while, so the cam 303 can be unlocked after a while, and the cam 303 can be unlocked after a while, and the cam 303 can be unlocked after a while, and the cam 303 can be unlocked after a while, and the cam 303 can be unlocked after a while, and the cam 303 can be unlocked after a while, and the cam 303 can be unlocked after a while, and the cam 303 can be unlocked after a while, and the cam 303 and the cam 302 can be unlocked after a while, and the cam 303 and the cam 302 can be unlocked after a while, and the cam 303 and the cam 302 can be unlocked after a while, and the cam 303 and the cam 302 can be unlocked after a Furthermore, outer ends of the anti-slip studs 305 at both sides, which are away from each other, are coaxially fixed with handles 304 for easy holding, so that the anti-slip studs 305 can be driven to rotate by applying force by holding the handles 304 .

[0036] Specifically, regarding the lateral displacement assembly 1, the guide groove 101 is a waist-shaped long groove arranged in the transverse direction, and the outer diameters of the fixing collar 104 and the limiting nut 103 are both larger than the longitudinal groove width of the guide groove 101. This arrangement ensures that the fixing collar 104 and the limiting nut 103 can vertically limit the threaded sleeve 102 in the guide groove 101, thereby allowing the threaded sleeve 102 to smoothly slide and change its position laterally along the guide groove 101. Further, optionally, the fixing collar 104 is coaxially fixed to the outer periphery of the threaded sleeve 102 in an interference fit manner, and the limiting nut 103 is a hand-tightened knurled nut. This arrangement first facilitates the quick assembly of the fixing collar 104 and the threaded sleeve 102, and at the same time facilitates the direct tightening of the limiting nut 103 by hand.

[0037] With the above structure, specifically in the process of using chili powder for microbial detection, the chili powder to be detected is evenly spread on the detection plate 201. Since the U-shaped bracket 4 is provided with the microbial detector probe body 5 through the lateral displacement component 1, and the microbial detector probe body 5 is located above the detection plate 201, the lateral position of the microbial detector probe body 5 can be adjusted by sliding the threaded sleeve 102 of the lateral displacement component 1 along the guide groove 101 laterally, thereby facilitating the microbial detection operation at different points in the lateral direction of the flattened chili powder. Since there is a certain trajectory in the lateral direction during the detection process, it can prevent the occurrence of certain positions. The situation that the chili noodles are missed in the inspection is ensured, which ensures that the flat chili noodles can be fully inspected. In addition, since longitudinal displacement components 3 are installed on both sides of the top surface of the workbench body 2, and the bottoms of both sides of the U-shaped bracket 4 are fixedly connected to the longitudinal displacement components 3 on the same side, the slider 303 of the longitudinal displacement component 3 slides along the slide groove 302, which can drive the U-shaped bracket 4 and the microorganism detector probe body 5 to slide longitudinally, and then adjust the longitudinal position of the microorganism detector probe body 5, so as to facilitate the microorganism detection operation at different points in the longitudinal direction of the flat chili noodles. Since there is a certain trajectory in the longitudinal direction during the detection process, it can prevent The situation that the chili noodles in some positions are missed in the inspection is now found, which further ensures that the flat chili noodles can be fully inspected. Specifically, in the process of combining the microbial detector probe body 5 with the U-shaped bracket 4 through the lateral displacement component 1, it is only necessary to twist the limiting nut 103 of the lateral displacement component 1 to disengage from the top of the threaded sleeve 102, so that the threaded sleeve 102 can slide vertically along the guide groove 101 and disengage from each other, and then the threaded sleeve 102 and the microbial detector probe body 5 can be disassembled from the U-shaped bracket 4 together. The disassembly method of the microbial detector probe body 5 and the U-shaped bracket 4 is simple and easy to implement, which is convenient for the subsequent disassembly of the microbial detector probe body 5 for inspection and maintenance. Specifically, in the process of combining the microbial detector probe body 5 with the U-shaped bracket 4 through the lateral displacement component 1, it is only necessary to twist the limiting nut 103 of the lateral displacement component 1 to disengage from the top of the threaded sleeve 102, so that the threaded sleeve 102 can slide vertically along the guide groove 101 and disengage from each other, and then the threaded sleeve 102 and the microbial detector probe body 5 can be disassembled from the U-shaped bracket 4 together. In the setting of component 3, since the mounting holes 306 at the front position of the longitudinal displacement component 3 are all laterally interspersed with anti-detachment studs 305, and the inner ends of the anti-detachment studs 305 are all inserted into the corresponding front ends of the slide grooves 302, the setting of the anti-detachment studs 305 can prevent the slider 303 from accidentally sliding out from the front end along the slide groove 302, ensuring that the microbial detection process of the chili powder can be carried out smoothly. The slider 303 can be separated and reassembled from the front end along the slide groove 302 by only making the anti-detachment studs 305 disengage from the mounting holes 306. The separation and reassembly of the slider 303 and the slide groove 302 are simple and easy to implement, which is convenient for regular cleaning and maintenance of the slider 303 and the slide groove 302.
