DETAILED DESCRIPTION

[0018] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present application belongs.

[0019] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0020] like Figures 1 to 5 As shown, a carbon dioxide constant temperature incubator includes a box body 100 with a culture chamber in the middle, wherein the culture chamber is provided with several layers of culture trays 200, and support mechanisms 300 for placing the trays are provided on both sides of the culture chamber; the support mechanism 300 includes two vertical support rails 310 arranged one in front of the other, and a plurality of support bars 320 for supporting the bottom of the culture tray are connected between the two vertical support rails. The vertical support rails can slide up and down relative to the side walls of the culture chamber, and an adjustment mechanism for adjusting the height of the vertical support rails is provided below the vertical support rails. The bottom of the culture tray is placed on the support bars of the support mechanisms on both sides. The support mechanisms 300 on both sides have a total of four vertical support rails, corresponding to the four corner positions of the culture tray respectively. When the culture tray is tilted, the height of the vertical support rail on the higher side of the culture tray can be lowered or the height of the vertical support rail on the lower side can be raised to keep the culture tray in a horizontal state. During the adjustment process, a level can be placed on the culture tray to ensure that the adjustment is in place.

[0021] In this embodiment, the upper and lower ends of the vertical support rail are respectively provided with vertical slide grooves 311, and the side wall of the culture chamber where the vertical support rail is located is provided with two limiting rods 330, one above and one below, which pass through the vertical slide grooves at the upper and lower ends of the vertical support rail respectively. The end of the limiting rod is provided with an anti-slip head 331 with a diameter greater than the width of the vertical slide groove and stuck on the outside of the vertical slide groove, and the lower end of the vertical slide groove is provided with a circular hole 312 which is connected to the vertical slide groove and has a diameter greater than the anti-slip head. The vertical support rail is connected to the side wall of the culture chamber in a detachable manner. When all the trays in the culture chamber are taken out, the vertical support rail is pushed upward so that the anti-detachment head 331 is in the round hole 312 and the vertical support rail can be removed; the working position of the vertical support rail is that the limit rod 330 is located in the vertical slide groove 311, and the vertical slide groove 311 and the limit rod 330 are used to guide the up and down sliding of the vertical support rail to avoid the vertical support rail position from being skewed, so as to ensure that the culture tray is in a horizontal state.

[0022] In this embodiment, the adjustment mechanism comprises a fixing plate 340 fixedly connected to the side wall of the culture chamber. Threaded holes extend through the upper and lower sides of the fixing plate, and adjustment bolts 350 are threadedly connected to the holes. The upper end of the adjustment bolts abuts the lower end of the vertical support rail. By rotating the adjustment bolts 350 and adjusting the length of the bolts extending upward from the fixing plate 340, the height of the vertical support rail can be adjusted. This provides convenient adjustment, a simple structure, and ease of operation.

[0023] In this embodiment, hooks 321 are provided at the front and rear ends of the support bar 320. The vertical support rail is provided with a plurality of vertically spaced connection holes 313 that engage with the hooks of the support bar. The ends of the support bar 320 are hooked to the vertical support rail, allowing for easy adjustment of the support bar's position, and thus the height of each culture tray.

[0024] In this embodiment, a water storage tray 400 is provided at the bottom of the culture chamber.

[0025] In this embodiment, the culture chamber has a glass inner door 500 on the front. The right side of the glass inner door is hinged to the right side of the culture chamber doorway. A lock 110 is located on the left side of the culture chamber doorway. A knob 510 is located near the lock on the glass inner door 500. A locking tab 511 is located on the side of the knob and engages with the lock. A sealing strip is provided at the edge of the culture chamber doorway. The glass inner door 500 allows for observation of the cultured cells or tissues while the culture chamber is sealed.

[0026] In this embodiment, a box door 600 covering the glass inner door is provided on the front side of the box body.

[0027] The improvement of the carbon dioxide constant temperature incubator of the present invention lies in the addition of a tray level adjustment function and a glass inner door. As for other structures such as temperature adjustment and carbon dioxide input and adjustment, existing technologies are still used and these structures will not be elaborated on here.

Therefore, only some numerical values ​​are disclosed in the present invention to illustrate the technical solution of the present invention. Furthermore, the numerical values ​​listed above should not be construed as limiting the scope of protection of the present invention.

[0029] If the present invention discloses or involves components or structural parts that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by integral molding using a casting process) (except where it is obviously not possible to use an integrated molding process).

[0030] In addition, unless otherwise stated, the terms used in any technical solution disclosed in the above-mentioned utility model to express positional relationships or shapes include states or shapes that are approximate, similar or close thereto.
