Detailed Implementation

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 This is a schematic diagram of the overall structure of the adjustable homogenizing bag opener for microbial testing provided by this utility model. Figure 2 This is a structural schematic diagram of the fixing mechanism in this utility model; Figure 3 This is a schematic diagram of the structure of the support bag spring in this utility model; Figure 4 This is a schematic diagram of the structure of the first spring in this utility model; Figure 5 This is a schematic diagram of the guiding telescopic component in this utility model. The adjustable homogenizing bag opening device for microbial testing includes a base plate 11, two symmetrically arranged adjustment mechanisms 12 on the top of the base plate 11, and a fixing mechanism 13 detachably arranged between the two adjustment mechanisms 12.

[0023] The fixing mechanism 13 includes a support plate 131, two first baffles 132 symmetrically arranged at both ends of the support plate 131, two support springs 133 symmetrically arranged at the middle of both sides of the support plate 131, a guide telescopic assembly 134 fixedly arranged on the outside of the first baffles 132, and connecting blocks 135 respectively fixedly arranged on the top sides of the guide telescopic assembly 134. The support plate 131 has inverted T-shaped grooves 1311 symmetrically arranged at both ends extending along the length of the support plate 131. The bottom of the first baffles 132 has T-shaped sliders 1321 corresponding to the inverted T-shaped grooves 1311. The T-shaped sliders 1321 slide against the inverted T-shaped grooves 1311. The bag support spring 133 is connected in a moving fit. It includes a first spring 1331 and a second spring 1332. The first spring 1331 is vertically arranged on the support plate 131. The outer side of the first spring 1331 is provided with a first sliding groove 1333. The lower end of the second spring 1332 is attached to the outer side of the first spring 1331 and is slidably connected to the first sliding groove 1333. The outer side of the upper end of the second spring 1332 is provided with a second sliding groove 1334. The connecting block 135 is slidably connected to the second sliding groove 1334. The inner side of the upper end of the second spring 1332 is provided with a rubber strip 136. The guide telescopic assembly 134 is detachably connected to the end of the adjacent adjustment mechanism 12. The adjustable homogenizing bag opening device for microbial testing described in this utility model, through the cooperation of the adjustment mechanism 12, the support plate 131, the first baffle 132, the first spring 1331, the second spring 1332, and the guide telescopic component 134, allows the internal space of the fixing mechanism 13 to be adjusted according to the size of the homogenizing bag, improving its applicability. It also allows for faster and more convenient opening of the homogenizing bag, facilitating the insertion of samples and the pouring of diluents. At the same time, it provides good support for the homogenizing bag body, eliminating the need to hold the homogenizing bag opening device or support the bag by hand, thus ensuring the stability of the bag.

[0024] Furthermore, the second spring piece 1332 includes a first vertical connecting portion 1335, an inclined connecting portion 1336, and a second vertical connecting portion 1337 connected sequentially from bottom to top. The first vertical connecting portion 1335 is attached to the outer side of the first spring piece 1331 and slidably connected to the first sliding groove 1333. The inclined connecting portion 1336 is inclined inward along the central axis of the support plate 131. The adhesive strip 136 is provided on the inner side of the second vertical connecting portion 1337, and the second sliding groove 1334 is provided on the outer side of the second vertical connecting portion 1337. This arrangement allows for a tighter fit between the first vertical connecting portion 1335 and the first spring piece 1331, ensuring that the first vertical connecting portion 1335 slides relative to the first sliding groove 1333 on the outer side of the first spring piece 1331, thus guaranteeing the stability of the bag-supporting spring piece 133 in supporting the homogenized bag.

[0025] Specifically, the second spring piece 1332 is integrally formed, which can ensure the overall strength of the second spring piece 1332 and further ensure the stability of the homogenized bag.

[0026] Further, the guide telescopic assembly 134 includes an upper guide sleeve 1341, a lower guide sleeve 1342, a guide rod 1343, a first spring 1344, and a fixing plate 1345. The upper guide sleeve 1341 and the lower guide sleeve 1342 are arranged opposite to each other, and the lower end of the upper guide sleeve 1341 extends into the end of the adjusting mechanism 12 and is detachably connected to the adjusting mechanism 12. The upper end of the lower guide sleeve 1342 extends into the end of the adjusting mechanism 12 and is slidably connected to the adjusting mechanism 12. The bottom of the lower guide sleeve 1342 is fixedly connected to the first baffle 132. The upper guide sleeve 1341... An inner sleeve 1346 is coaxially arranged inside the upper guide sleeve 1341 and the lower guide sleeve 1342 is coaxially arranged inside the lower guide sleeve 1342. The upper end of the guide rod 1343 extends into the inner sleeve 1346 and is slidably connected to the inner sleeve 1346. A first spring 1344 is sleeved on the outside of the inner sleeve 1346 and the guide rod 1343, and the two ends of the first spring 1344 are respectively connected to the ends of the upper guide sleeve 1341 and the lower guide sleeve 1342. A fixing plate 1345 is provided on the top of the upper guide sleeve 1341, and the two ends of the fixing plate 1345 are respectively provided with the connecting block 135. With this configuration, when the adjusting mechanism 12 drives the guide telescopic assembly 134 to slide along the inverted T-shaped groove 1311, the upper guide sleeve 1341 and the lower guide sleeve 1342 bear the force from the adjusting mechanism 12 in the horizontal direction. This effectively protects the first spring 1344 located on the upper guide sleeve 1341 and the lower guide sleeve 1342, preventing the first spring 1344 from deforming due to the horizontal force, which would affect the normal use of the guide telescopic assembly 134 and ensure the service life of the adjustable homogenizing bag opening device for microbial testing.

[0027] Further, the adjustment mechanism 12 includes a support rod 121, a mounting rod 122, a pin 123, a second baffle 124, and a second spring 125. The support rod 121 is vertically fixed to the top of the base plate 11, and the support rod 121 has a through hole (unmarked) arranged in the horizontal direction and a pin hole 1211 arranged vertically to and corresponding to the through hole (unmarked). The mounting rod 122 passes horizontally through the through hole (unmarked) and can slide along the inner wall of the through hole (unmarked). The surface of the mounting rod 122 has a plurality of evenly arranged fixing holes 1221. One end of the pin 123 passes through the pin hole 1211 and the fixing hole 1221 in sequence. The second baffle 124 is fixed to the end of the mounting rod 122 away from the fixing mechanism 13. The second spring 125 is sleeved on the mounting rod 122, and the two ends of the second spring 125 are respectively connected to the second baffle 124 and the support rod 121. With this configuration, when adjusting the position of the first baffle 132, the pin 123 is first pulled out from the pin hole 1211 and the corresponding fixing hole 1221. Then, the second baffle 124 is pulled, causing the mounting rod 122 to slide on the support rod 121, thereby driving the first baffle 132 to slide along the inverted T-shaped groove 1311. After adjustment, the pin 123 is reinserted into the pin hole 1211 and the corresponding fixing hole 1221 to fix the mounting rod 122 to the support rod 121. Finally, the same operation steps are used to adjust the position of the other first baffle 132, so that the distance between the two first baffles 132 can adapt to homogenization bags of different specifications, thus improving the applicability of the adjustable homogenization bag opener for microbial testing.

[0028] Specifically, multiple through holes (unmarked) and pin holes 1211 are provided. These multiple through holes (unmarked) are evenly distributed vertically on the support rod 121, and each of the multiple pin holes 1211 corresponds one-to-one with a single through hole (unmarked). This arrangement allows for adjustment of the position of the mounting rod 122 on the support rod 121, ensuring sufficient distance between the bottom of the fixing mechanism 13 and the top of the base plate 11. This allows the fixing mechanism 13 to better accommodate homogenizing bags of different sizes, further improving the applicability of the adjustable homogenizing bag opener for microbial testing.

[0029] Furthermore, the support plate 131, the first baffle 132, the bag-supporting spring 133, and the connecting block 135 are all made of elastic PC material. This not only effectively reduces the overall weight of the fixing mechanism 13 and the load on the adjusting mechanism 12, thus improving the stability of the adjustable homogenizing bag opening device used for microbial testing, but also effectively ensures the mechanical strength and elastic coefficient of the support plate 131, the first baffle 132, the bag-supporting spring 133, and the connecting block 135, thereby ensuring the stability of the support plate 131, the first baffle 132, the bag-supporting spring 133, and the connecting block 135 in supporting the homogenizing bag.

[0030] Furthermore, the adhesive strip 136 can be a horizontal strip or multiple vertical strips. This design facilitates the placement of the adhesive strip 136 and ensures that the adhesive strip 136 can effectively adhere to the outer side of the homogenizing bag opening.

[0031] Specifically, the adhesive strip 136 can be made of double-sided adhesive or disposable adhesive, which is low in cost.

[0032] In use, the adjustable homogenizing bag opening device for microbial testing of this utility model involves adjusting the position of the mounting rod 122 on the support rod 121 according to the specific specifications of the homogenizing bag. This ensures sufficient distance between the bottom of the fixing mechanism 13 and the top of the base plate 11, allowing the fixing mechanism 13 to better adapt to homogenizing bags of different specifications. Then, the second baffle 124, the second spring 125, and the fixing mechanism 13 are installed, and the mounting rod 122 is fixed to the support rod 121 using the pin 123. Next, the distance between the two first baffles 132 is adjusted according to the specific specifications of the homogenizing bag. The pin 123 is first pulled out from the pin hole 1211 and the corresponding fixing hole 1221. Then, the second baffle 124 is pulled, causing the mounting rod 122 to slide on the support rod 121, thereby opening the bag. The first baffle 132 is slid along the inverted T-shaped groove 1311 and adjusted to the correct position. Then, the pin 123 is reinserted into the pin hole 1211 and the corresponding fixing hole 1221 to fix the mounting rod 122 and the support rod 121. Finally, the same operation steps are used to adjust the position of the other first baffle 132 so that the distance between the two first baffles 132 is adapted to the homogenizing bag. Finally, the homogenizing bag is placed in the space between the two first baffles 132 and the two bag-supporting springs 133. The two sides of the bag opening of the homogenizing bag are respectively glued to the adhesive strips 136 on the upper end of the two bag-supporting springs 133. Under the elastic reset action of the bag-supporting springs 133, the bag opening of the homogenizing bag is opened. The bag body of the homogenizing bag is supported between the two first baffles 132 and the two bag-supporting springs 133, and the bottom of the homogenizing bag is supported on the support plate 131.
