Description

Technical Field

[0001] This utility model relates to the field of biological experimental equipment, and in particular to a stem cell culture bag mounting device that is easy to replace. Background Technology

[0002] Currently, stem cell culture technology has become an important component of life science research and clinical treatment. To ensure that the stem cell culture process meets experimental requirements, stem cell culture bags, as containers for culturing stem cells, are widely used in cell culture processes.

[0003] To address the need for mounting stem cell culture bags, existing technologies typically employ fixing plates and support frames. Generally, these mounting devices are secured to the support plates with bolts and nuts. While this design fulfills the basic functions of mounting and support, the overall structure is relatively simple, disassembly is inconvenient, the fixing method is limited, and there is a lack of optimization for the stability and ease of replacement of the culture bags.

[0004] However, existing stem cell culture bag mounting devices have significant structural limitations. First, most existing mounting devices lack protection for the stem cell culture bags, making them susceptible to external damage. Furthermore, the installation and removal of protective devices are cumbersome, making it inconvenient for researchers to observe and record the stem cell culture bags. In addition, existing devices do not provide a sufficiently convenient mechanism for replacing the mounting device, and users usually need to disassemble multiple parts or make rather complicated adjustments to complete the replacement.

[0005] To address the above issues, a replaceable stem cell culture bag mounting device is proposed. Summary of the Invention

[0006] To overcome the above shortcomings, this utility model provides a stem cell culture bag mounting device that is easy to replace, aiming to improve the problem of the lack of protection for stem cell culture bags in existing stem cell culture bag mounting devices.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a stem cell culture bag mounting device that is easy to replace, comprising a support plate and a square plate. The top of the support plate is connected to the square plate through a fixing mechanism. An angle adjustment support assembly is provided at the bottom of the square plate. A protective assembly is provided at the top of the square plate. The protective assembly includes a protective shell. A fixing block is provided on the outer side of the square plate. A sliding block two is fixedly connected to one end of the fixing block. An insertion post is provided inside the sliding block two. The insertion post is rotatably connected to the square plate. A ring is provided inside the square plate. A hook is provided on the outer side of the protective shell.

[0008] As a further description of the above technical solution:

[0009] The fixing mechanism includes a cylinder, inside which is a telescopic rod, and outside the telescopic rod is a retraction spring. A second cylindrical pin is located outside the telescopic rod, and a connecting rod is rotatably connected to the top of the second cylindrical pin. A first cylindrical pin is located outside the connecting rod, and one end of the first cylindrical pin is rotatably connected to a retraction rod.

[0010] As a further description of the above technical solution:

[0011] The hook has a bolt on its outer side.

[0012] As a further description of the above technical solution:

[0013] The square plate contains a stem cell culture bag, and the outside of the stem cell culture bag is provided with multiple fixing tubes.

[0014] As a further description of the above technical solution:

[0015] A support plate is fixedly connected to the bottom of the square plate, and a second retractable rod is fixedly connected to the bottom of the square plate. A first retractable rod is slidably connected to the bottom of the second retractable rod.

[0016] As a further description of the above technical solution:

[0017] The angle adjustment support assembly includes a retractable rod, a second insert pin rotatably connected to the bottom of the retractable rod, a first sliding block provided on the outer side of the insert pin, and a base plate fixedly connected to the bottom of the first sliding block.

[0018] As a further description of the above technical solution:

[0019] The square plate is rotatably connected to the insert inside the sliding block two.

[0020] As a further description of the above technical solution:

[0021] The connecting rod rotates inside the telescopic rod.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, a structure consisting of hooks, fixing plates, sliding blocks, inserts, and rings is used. When the protective shell is placed on the square plate, it is fixed by the hooks on the side of the protective shell and the fixing blocks on the outside of the square plate. The square plate drives the ring to cover the hooks and quickly lock them in place to protect the internal stem cell culture bag.

[0024] 2. In this utility model, with the cooperation of the retractable rod, cylindrical pin, connecting rod, telescopic rod, and retractable spring structure, when the cylinder inside the square plate is placed in the inner hole on both sides of the square plate, the telescopic rod rotates and drives the connecting rod inside the cylindrical pin to rotate. When rotating, the connecting rod drives the top retractable rod to extend outward for fixation, thus quickly fixing the plate. Attached Figure Description
