Description

Technical Field

[0001] This invention belongs to the field of microbiological devices, and in particular relates to a support for stacking culture dishes for food microbial detection. Background Technology

[0002] Petri dishes are laboratory consumables used for microbial culture. They consist of a circular base and a circular lid, and are usually made of glass or plastic. In biological laboratories, food testing laboratories, and other similar settings, they are commonly used for the culture of bacteria and molds. Currently, food microbial testing experiments generally require multiple parallel experiments, so each sample needs multiple petri dishes. The laboratory personnel then transfer the petri dishes to an incubator and stack them for cultivation.

[0003] While existing devices have solved the problem of transporting multiple stacked culture dishes, they are only suitable for stacking and transporting culture dishes of a single size. Larger culture dishes cannot be placed inside, and smaller culture dishes are prone to shaking and falling off during transport. Utility Model Content

[0004] The purpose of this invention is to provide a support for stacking culture dishes for food microbial testing, which facilitates the stacking and transportation of culture dishes of different sizes.

[0005] The aforementioned support for stacking culture dishes for food microbial testing includes two vertically distributed clamps. Each clamp consists of two fixed tubes, which are hinged to each other at their center points along their length, allowing them to swing left and right. Each fixed tube has a sliding connecting rod inserted into its movable end. The movable ends of the connecting rods on the same vertical line are connected by support rods. Several vertically distributed placement plates are horizontally arranged between the support rods. The front and rear sidewalls of the placement plates are connected to the support rods by connecting components, allowing them to slide vertically. The two connecting components are symmetrically distributed.

[0006] Furthermore, the connecting assembly includes a connecting rod, a slot for inserting the connecting rod is provided on the placement plate, a baffle is provided on the connecting rod located in the slot, a stop block is provided at the slot opening to prevent the baffle from falling off, a spring is fitted on the connecting rod between the baffle and the stop block, a second limiting block is fitted on the connecting rod located outside the slot and threadedly engaged with it, and a first through groove is provided on the support rod for the connecting rod to pass through, and the width of the first through groove is smaller than the diameter of the spring.

[0007] Furthermore, a sliding groove is horizontally provided on the inner sidewall of the slot, and a slider is provided in the sliding groove to slide back and forth with it. The slider is fixed to the sidewall of the baffle.

[0008] Furthermore, a fixing plate is horizontally arranged between the two fixing pipes located above. The fixing plate divides one of the fixing pipes into two sections, and both sections are fixed to the outer wall of the fixing plate. A second through groove is opened on the fixing plate for the other fixing pipe to pass through. A groove is opened at the center of the fixing plate in the second through groove. A bearing is installed in the groove, and a fixing rod is vertically inserted in the bearing. A through hole is opened on the fixing pipe in the second through groove for the fixing rod to pass through, and the fixing pipe is fixed to the fixing rod through the through hole. A channel is opened at the top of the fixing plate for the movable end of the fixing rod to pass through. A first limiting block is fitted on the fixing rod located outside the fixing plate and is threaded to it. The diameter of the channel is smaller than the diameter of the first limiting block.

[0009] Furthermore, each of the support rods is fitted with a protective sleeve.

[0010] Furthermore, the second through groove has an overall structure that is narrow in the middle and wide at both ends.

[0011] Furthermore, the two fixed pipes located below are arranged in a cross shape, and one of the fixed pipes has a third through groove at the bottom, while the other fixed pipe has a fourth through groove at the top with the same depth as the third through groove. The lengths of the third and fourth through grooves are the same as the width at the opening of the second through groove.

[0012] Furthermore, an annular groove is formed at the top of the fixing plate along the center of the fixing rod, and a pull ring that swings up and down is hinged in the annular groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention facilitates the placement and transport of culture dishes of different sizes by adjusting the connecting rod and support rod, and further improves its applicability by adjusting the up and down of the placement plate, making it more stable during transport.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention. Example 1

[0023] This embodiment describes a support for stacked culture dishes used in food microbiology testing, such as... Figure 1 As shown, it includes two clamping plates distributed vertically. The clamping plates are composed of two fixed tubes 1, and the center points of the two fixed tubes 1 are hinged to each other along the length direction to swing left and right, which facilitates the adjustment of the distance between two adjacent support rods 5 and makes it easy for the petri dish to pass through.

[0024] Each movable end of the fixed tube 1 is fitted with a connecting rod 2 that slides with it. The movable ends of the connecting rods 2 located on the same vertical line are connected by support rods 5, which makes it easier to adjust the distance between the two support rods 5 according to different sizes of petri dishes, thus making it more versatile.

[0025] Several vertically distributed storage plates 3 are horizontally arranged between the support rods 5, which facilitates the stacking and simultaneous transport of multiple culture dishes, thus improving efficiency.

[0026] The front and rear side walls of the placement plate 3 are connected to the support rod 5 through connecting components in an up-down sliding fit. The two connecting components are symmetrically distributed, which makes it easy to adjust the spacing between the placement plates 3 according to the usage requirements to facilitate the placement of the culture dish. The symmetrical distribution of the connecting components also makes it easy to connect the placement plate 3 with the two symmetrically distributed support rods 5, avoiding the placement plate 3 affecting the left and right swing of the support rod 5, making it easy for the culture dish to pass through.

[0027] A locking element is provided between the fixed tube 1 and the connecting rod 2 to fix the connecting rod 2 inside the fixed tube 1. The locking element can be a screw or a threaded rod. A threaded through hole is provided on the fixed tube 1 to facilitate tightening the connecting rod 2 by rotating the screw or threaded rod.

[0028] like Figure 5 and Figure 6As shown, the connecting assembly includes a connecting rod 10, a slot for inserting the connecting rod 10 is provided on the placement plate 3, a baffle 14 is provided on the connecting rod 10 located in the slot, a stop block is provided at the slot opening to prevent the baffle 14 from falling off, a spring 12 is fitted on the connecting rod 10 between the baffle 14 and the stop block, a second limiting block 11 is fitted on the connecting rod 10 located outside the slot and threadedly engaged with it, and a through groove is provided on the support rod 5 for the connecting rod 10 to pass through, and the width of the through groove is smaller than the diameter of the spring 12, which facilitates the vertical adjustment of the height of the placement plate 3 and also provides a certain buffering effect when the petri dish is impacted during transportation to avoid direct impact and damage.

[0029] The connecting assembly includes a connecting rod 10, which is horizontally fixed to the side wall of the shelf 3. The movable end of the connecting rod 10 is fitted with a second limiting block 11 that is threadedly engaged with it. The support rod 5 has a first through groove for the connecting rod 10 to pass through, and the width of the first through groove is smaller than the diameter of the spring 12, so as to facilitate the vertical adjustment of the height of the shelf 3, thereby facilitating the placement of culture dishes of different sizes.

[0030] like Figure 6 As shown, a sliding groove is horizontally opened on the inner side wall of the slot, and a slider 13 is provided in the sliding groove to slide back and forth with it. The slider 13 is fixed to the side wall of the baffle 14, which helps to increase the stability of the connecting rod 10 when it moves in the slot and prevents the placement plate 3 from shifting during the movement of the connecting rod 10, which would cause the culture dish to fall and be damaged.

[0031] Each of the support rods 5 is fitted with a protective sleeve 4, which increases friction and cushioning when the culture dish is placed on the shelf 3 and the support rods 5 are adjusted to hold the culture dish, thus preventing direct damage to the culture dish from impact.

[0032] like Figure 3 As shown, the second channel has a structure that is narrow in the middle and wide at both ends, which makes it easier for the upper fixed tube 1 to swing more left and right, thereby allowing the distance between the two adjacent support rods 5 to be adjusted to be greater, making it easier for large-sized petri dishes to pass through.

[0033] like Figure 3 and Figure 4 As shown, the two fixed tubes 1 located below are arranged in a cross shape, and one of the fixed tubes 1 has a third through groove at the bottom, and the other fixed tube 1 has a fourth through groove at the top with the same depth as the third through groove. The length of the third through groove and the fourth through groove are the same as the width at the opening of the second through groove, so that the swing angle of the fixed tubes 1 at the upper and lower ends is consistent. This can limit the swing amplitude of the fixed tubes 1 and avoid damage caused by inconsistent swing amplitude.

[0034] like Figure 2As shown, an annular groove is provided at the top of the fixing plate 8 along the center of the fixing rod 6. A pull ring 9 that swings up and down is hinged in the annular groove, which facilitates transportation by means of the pull ring 9. At the same time, when not needed, the pull ring 9 can be put into the annular groove to avoid increasing the space occupied and affecting the use.

[0035] The working principle is as follows: First, adjust the position of the connecting rod 2 according to the specifications of the petri dish so that the distance between the two supporting rods 5 is sufficient to place the petri dish. Then, adjust the height of the placement plate 3 through the connecting rod 10 and the second limiting block 11. Next, fix the position of the placement plate 3 through the second limiting block 11. Then, swing the fixing tube 1 and the supporting rod 5 left and right to increase the distance between the adjacent supporting rods 5, so that the petri dish can be placed on the placement plate 3. After the petri dish is placed, adjust the position of the connecting rod 2 and the supporting rod 5 again to fit with the petri dish, and fix the position of the connecting rod 2 through the screw. Finally, remove the pull ring 9 from the annular groove and carry it for transfer. Example 2

[0036] This embodiment further illustrates the technology, such as Figure 1 , Figure 2 ,and Figure 3 As shown, a fixing plate 8 is horizontally arranged between the two fixing tubes 1 located at the top. The fixing plate 8 divides one of the fixing tubes 1 into two sections, and both sections of the fixing tube 1 are fixed to the outer wall of the fixing plate 8. A second through groove is opened on the fixing plate 8 for the other fixing tube 1 to pass through. A groove is opened at the center of the fixing plate 8 located in the second through groove. A bearing is installed in the groove, and a fixing rod 6 is vertically inserted in the bearing. A through hole is opened on the fixing tube 1 in the second through groove for the fixing rod 6 to pass through, and the fixing tube 1 is fixed to the fixing rod 6 through the through hole. A channel is opened at the top of the fixing plate 8 for the movable end of the fixing rod 6 to pass through. A first limiting block 7 is fitted on the fixing rod 6 located on the outside of the fixing plate 8 and is threaded to it. The diameter of the channel is smaller than the diameter of the first limiting block 7. This facilitates the rotation of the fixing tube 1 to allow different sizes of culture dishes to pass through. It also increases the stability of the fixing plate 8, the fixing rod 6 and the first limiting block 7. This allows the support rod 5 to stably clamp and fix the culture dish during transportation, preventing the culture dish from slipping and being damaged.
