Description

Technical Field

[0001] This utility model relates to the field of homogenizing bag opening technology, specifically a convenient homogenizing bag opening device. Background Technology

[0002] The total bacterial count test is a commonly used basic experiment in microbial testing. It is used to determine the number of viable bacteria in a sample and is widely used in the evaluation of hygiene quality in the fields of food, water, cosmetics, and medicine. The total bacterial count refers to the number of colonies formed per gram of sample after incubation under certain conditions. When conducting the total bacterial count test on wet wipes or wet toilet paper in the laboratory, a certain amount of experimental solution needs to be weighed.

[0003] Current homogenizer bag openers require both hands to squeeze the adhesive to adhere to the outer wall of the homogenizer bag for easy opening. Since the size of the opening is determined by the tightness of the screw at the bottom of the opener, it cannot completely secure the bottom of the homogenizer bag, and the screw is prone to loosening over time. The opening size cannot be kept consistent and requires constant tightening of the screw. Furthermore, since there is no fixed force point above the opening of the homogenizer bag, the force is uneven during squeezing, which can lead to cracks or even breakage of the opener. Utility Model Content

[0004] The purpose of this invention is to provide a convenient homogenizing bag opening device to solve the problems mentioned in the background art, where the opening size of the homogenizing bag is determined by the tightness of the screw at the bottom of the opening device, which cannot completely fix the bottom of the homogenizing bag, and the screw is prone to loosening over time. The opening size cannot be kept consistent and the screw needs to be constantly tightened to fix it. Furthermore, since there is no fixed force point above the opening of the homogenizing bag, the force is uneven during compression, which leads to cracks or even breakage of the opening device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a convenient homogenizing bag opening device, comprising a fixed base plate, on which two supporting rotating blocks are mounted. A first connecting plate is fixedly connected to the upper end of one of the supporting rotating blocks, and a second connecting plate is fixedly connected to the upper end of the other supporting rotating block. Positioning slots are provided on the facing surfaces of the first and second connecting plates. A supporting slide rod is installed through the inner wall of the positioning slot. A supporting slider is provided on the inner wall of the positioning slot. A tearable adhesive is fixedly connected to the surface of the supporting slider. A groove is provided on the side surface of the supporting slider, and an adjusting stud is installed on the inner wall of the groove. An opening handle is installed on the outer surface of both the first and second connecting plates. An adjusting mechanism is provided between the first and second connecting plates, which allows the supporting blocks to be easily engaged into the grooves of different heights for limiting the position by rotating the supporting blocks.

[0006] Preferably, the fixed base plate and the supporting rotating block are rotatably connected, and the positioning slot and the supporting slide rod are slidably connected.

[0007] By adopting the above technical solution, the design allows the first and second connecting plates to rotate flexibly with the supporting rotating block as the fulcrum, making it easy to adjust the opening angle between the two connecting plates, thereby adapting to the opening requirements of homogenizing bags of different specifications and making the operation more flexible.

[0008] Preferably, the positioning slot and the supporting slider form a sliding connection, and the side surface of the supporting slider is fixedly connected to the supporting slide rod, and the tearable adhesive has a multi-layer design.

[0009] Using the above technical solution, the supporting slider can slide along the positioning slot. At the same time, the fixed connection with the supporting slide rod ensures the synchronicity and stability of its sliding process, making it convenient to adjust the supporting position according to the size of the homogenizing bag and enhancing the adaptability to the homogenizing bag.

[0010] Preferably, the adjusting stud and the supporting slider are threadedly connected, and the adjusting stud penetrates the inner wall of the positioning slot. The two adjusting studs are respectively rotatably connected to the first connecting plate and the second connecting plate.

[0011] By adopting the above technical solution, the position of the support slider in the positioning slot can be precisely controlled by rotating the adjusting stud and using the threaded transmission, so as to achieve precise adjustment of the fixed position of the homogenizing bag. The rotational connection between the adjusting stud and the connecting plate ensures the smoothness of the adjustment operation, can stably maintain the position of the support slider, avoid loosening due to long-term use, and ensure the consistency of the opening size of the homogenizing bag.

[0012] Preferably, the two opening handles are rotatably connected to the first connecting plate and the second connecting plate, and a return spring is connected between the outer surface of the first connecting plate and the outer surface of the second connecting plate and the upper surface of the fixed base plate.

[0013] By adopting the above technical solution, the open handle can rotate flexibly, allowing operators to adjust the grip angle according to their hand habits, thereby improving operating comfort and reducing operator fatigue.

[0014] Preferably, the adjustment mechanism includes a support block, which is installed on the outer surface of the second connecting plate, and a locking block is fixedly connected to the side surface of the first connecting plate.

[0015] By adopting the above technical solution, the adjustment mechanism provides a reliable limiting method for the first connecting plate and the second connecting plate. Through the cooperation of the support block and the locking block, the opening angle between the two connecting plates can be stably maintained, ensuring that the opening size of the homogenizing bag is fixed, thus solving the problem of the opening size of traditional opening devices being easily variable.

[0016] Preferably, the support block has a concave design and is rotatably connected to the first connecting plate, and the locking block is arranged vertically and is designed to be inclined upward.

[0017] The above technical solution uses a concave design to allow the support block to be more securely engaged with the locking block, enhancing the limiting effect. The rotating connection allows the support block to be easily adjusted to fit locking blocks of different heights.

[0020] 2. The automatic reset function of the return spring and the flexible rotation design of the opening handle improve the ease of operation. At the same time, the rotational connection between the support block and the fixed base plate enables the device to adapt to different sizes of homogenizing bags, thus enhancing its adaptability.

[0021] 3. The cooperation between the support block and the locking block in the adjustment mechanism, through the concave design and the upward tilting vertical arrangement, achieves reliable locking of the opening angle, avoids damage to the device caused by uneven force during extrusion, and extends the service life.
