DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-2 The specific implementation modes of the present utility model are further described in detail.

[0023] Depend on Figure 1-2 The utility model provides a lifting bracket for a cell culture bag, comprising:

[0024] A fixed seat 1, two slide seats 2 are slidably provided on both sides of the surface of the fixed seat 1, and a width adjustment mechanism 3 for adjusting the distance between the two slide seats 2 is provided on the fixed seat 1;

[0025] There are two cell bag support plates 4, which are used to hold up the cell bag 5 from both sides. The lower ends of the two cell bag support plates 4 are rotatably connected to the upper ends of the two slides 2, respectively, and the slides 2 are provided with an angle adjustment mechanism 6 for adjusting the opening angle of the cell bag support plates 4;

[0026] The two ends of the support belt 7 are respectively fixedly connected to the lower ends of the two cell bag support plates 4;

[0027] When in use, the width adjustment mechanism 3 drives the two slide seats 2 to slide on the fixed seat 1, adjusts the distance between the two cell bag support plates 4, and then adjusts the opening angle of the two cell bag support plates 4 through the angle adjustment mechanism 6, so that the two cell bag support plates 4 are opened like two palms to form a V-shaped supporting structure, and then the cell culture bag with cells cultured is placed between the two cell bag support plates 4, and the cell bag 5 is supported by the two cell bag support plates 4, so that the cell bag 5 is kept in a relatively stable shape, so that sampling is more convenient.

[0028] In some embodiments, the width adjustment mechanism 3 includes a slide groove 31 embedded in the surface of the fixed seat 1 and a bidirectional threaded rod 32 rotatably arranged in the slide groove 31. The lower ends of the two slides 2 are slidably connected to the slide groove 31, and the two slides 2 are respectively threadedly connected to the two ends of the bidirectional threaded rod 32. When the bidirectional threaded rod 32 is rotated, the two slides 2 can be driven to move closer to or away from each other, thereby facilitating the adjustment of the distance between the two thin bag pallets 4.

[0029] In some embodiments, the angle adjustment mechanism 6 includes a fixed slide rail 61 fixed on both sides of the fixed seat 1, a transverse slide rail 62 is provided in the fixed slide rail 61 for vertical sliding, two tooth plates 63 are provided in the transverse slide rail 62 for sliding, a gear 64 is fixed to one end of the rotating shaft at the lower end of the cell bag support plate 4, the gear 64 and the tooth plate 63 are meshed and connected, and a limiting sleeve 66 for limiting the tooth plate 63 to slide in the vertical direction is provided on the slide seat 2. Through the setting of the limiting sleeve 66, the tooth plate 63 is always connected to the slide seat 2, and under the restriction of the limiting sleeve 66, the tooth plate 63 can only slide in the vertical direction relative to the slide 2. When the slide 2 slides, the tooth plate 63 will slide together with the slide 2. However, since the lower end of the tooth plate 63 is slidably connected to the transverse slide rail 62, it always remains connected to the transverse slide rail 62. When adjusting the opening angle of the cell bag support plate 4, the transverse slide rail 62 can be driven to slide the two tooth plates 63 together in the vertical direction by sliding the transverse slide rail 62 in the vertical direction. When the tooth plate 63 slides, it drives the gear 64 to rotate. When the gear 64 rotates, it drives the cell bag support plate 4 to rotate, thereby adjusting the opening angle of the cell bag support plate 4.

Through the setting of the negative pressure mechanism 8, after the cell bag 5 is placed between the two cell bag support plates 4, the negative pressure fan 82 is turned on to generate negative pressure in the cavity 81, thereby generating attraction on both sides of the surface of the cell bag 5, so that the mouth of the cell bag 5 can be better opened to facilitate sampling.

[0032] An elastic cloth 9 is connected between the sides of the two cell bag support plates 4. The support belt 7 and the elastic cloth 9 are integrally formed, and can close the bottom and sides of the cell bag support plates 4.

[0033] Working principle: When the utility model is in use, the distance between the two cell bag support plates 4 is adjusted by the width adjustment mechanism 3, and then the opening angle of the two cell bag support plates 4 is adjusted by the angle adjustment mechanism 6, so that the two cell bag support plates 4 are opened like two palms, and the cell culture bag with cells cultured is placed between the two cell bag support plates 4. The cell bag 5 is supported by the two cell bag support plates 4, so that the cell bag 5 is kept in a relatively stable shape, thereby making sampling more convenient. In addition, a negative pressure mechanism 8 is provided on the back of the two cell bag support plates 4. When sampling, the negative pressure fan 82 is turned on to generate negative pressure in the cavity 81, which generates attraction on both sides of the surface of the cell bag 5, so that the mouth of the cell bag 5 can be better opened, which is convenient for sampling.
