DETAILED DESCRIPTION

[0008] The present application will be further described below in conjunction with the accompanying drawings and some embodiments. The following embodiments are mainly used to exemplarily illustrate the technical solution of the present application, and therefore cannot be used to limit the protection scope of the present application.

[0009] Unless otherwise defined, the technical and scientific terms used herein have the same meanings as those commonly understood by technicians in the technical field to which this application belongs; the terms used herein are mainly used to describe specific embodiments and are not intended to limit this application; the terms "include", "have", "comprise" and other synonyms with the same or similar meanings in the specification and claims of this application and the above-mentioned figure descriptions are intended to cover non-exclusive inclusions.

It will be understood by those skilled in the art that the embodiments described herein may be combined with other embodiments in this article or other embodiments outside this article.

[0012] In the description of the embodiments of the present application, technical terms used to indicate orientation or positional relationships, such as "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., are mainly used to facilitate the description of the embodiments of the present application and simplify the description, and are not considered to mean that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0013] In the various embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "set", "install", "assemble", "connect", "connect", "fix" and the like should be understood in a broad sense. Taking connection as an example, it may include fixed connection, detachable connection or integral molding; it may also include at least one of mechanical connection and electrical connection; it may include direct connection or indirect connection through an intermediate medium. A person of ordinary skill in the art can understand the specific meanings of the above terms in the embodiments of the present application according to the specific circumstances.

[0014] See also Figure 1 The present application provides an incubator 1, which may be a carbon dioxide incubator 1. The incubator 1 may include a box body 10, and an inner door 20 and an outer door 30 disposed on the box body 10. The inner door 20 and the outer door 30 can be opened and closed independently. When the outer door 30 and the inner door 20 are closed, the inner door 20 is located between the box body 10 and the outer door 30, and a rotary door lock 40 is disposed on the inner door 20. When the incubator 1 is closed, the inner door 20 is generally closed first, and then the outer door 30 is closed.

[0015] See also Figure 2 , the inner door 20 may include an outer frame 22 and at least one small door 21 arranged on the outer frame 22, and the small door 21 can rotate relative to the outer frame 22. A rotating handle 41 is arranged on the small door 21, and a locking ring 50 is arranged on the outer frame 22. The rotating handle 41 on the small door 21 can be locked on the locking ring 50, thereby closing the small door 21. In this case, the small door 21 can be opened and closed individually. Since the incubator 1 may have multiple layers, this structure can open the small door 21 of a certain area individually without opening the entire inner door 20. Compared with opening the entire inner door 20 normally, the environmental changes inside the incubator 1 can be reduced when the small door 21 is opened.

[0016] Of course, the outer frame 22 may also be provided with a rotating handle 41, and the box body 10 may be provided with a locking ring 50. In this way, the entire inner door 20 may also be opened and closed. The rotating handle 41 provided on the outer frame 22 or the rotating handle 41 provided on the small door 21 may adopt the following structure.

[0017] See also Figure 3 and Figure 4 The rotary door lock 40 includes a rotary handle 41, a locking block 42, and a locking block shaft pin 43 fixed to the inner door 20. The locking block 42 is rotatably arranged on the locking block shaft pin 43, and the rotary handle 41 is arranged on the locking block 42. The locking block 42 may have a locking portion. When the user rotates the rotary handle 41 to make the locking portion move to the bottom of the lock ring 50, the small door 21 or the inner door 20 can be closed. When the user rotates the rotary handle 41 to make the locking portion move away from the bottom of the lock ring 50, the small door 21 or the inner door 20 can be opened.

[0018] Compared with the existing rotary door lock 40 which is directly rotatably arranged on the inner door 20, the locking block 42 of the present application can rotate around the locking block shaft pin 43, and the locking block shaft pin 43 is fixed on the inner door 20, which can reduce the possibility and frequency of the entire rotary door lock 40 rotating relative to the inner door 20, thereby improving the stability of the rotary door lock 40 structure and reducing the possibility of it falling off from the inner door 20 after a period of use.

[0019] The rotating handle 41 may be made of a high temperature resistant material, such as plastic, and its thermal conductivity may be greater than 0.2 or 0.4 W / (m•K). This can reduce the high temperature transfer inside the incubator 1 and reduce the risk of the user being burned by high temperature when opening and closing the door.

[0020] The locking block 42 is provided with a mounting hole 420, and the locking block shaft pin 43 is passed through the mounting hole 420, so that the locking block 42 can rotate around the locking block shaft pin 43. The locking block shaft pin 43 can be matched with the mounting hole 420 to reduce the rotation of the locking block shaft pin 43 when the locking block 42 rotates.

[0021] The locking block shaft pin 43 includes a neck 431 and a cap 432. In the axial projection direction parallel to the locking block shaft pin 43, the projection of the neck 431 falls into the projection of the cap 432, and the neck 431 is penetrated into the mounting hole 420. The cross section of the neck 431 can be smaller than the cross section of the cap 432, so that the cap 432 has a certain limiting effect. For example, the neck 431 and the cap 432 can be cylinders, and the diameter of the cap 432 is larger than that of the neck 431, which can facilitate the processing of the locking block shaft pin 43. Of course, the neck 431 can also be prismatic. The shape of the cap 432 can also be prismatic, table-shaped, hemispherical or other structures, which are not specifically limited here.

[0022] The rotary door lock 40 further includes an axle pin flange 44, which is threadedly connected to the neck 431 of the locking block axle pin 43, so that the locking block 42 is limited by the cap 432 and the axle pin flange 44. In other words, the presence of the axle pin flange 44 can limit the movement of the locking block 42 toward the side where the inner door 20 is located, and the presence of the cap 432 can limit the movement of the locking block 42 toward the side away from the inner door 20. When the axle pin flange 44 is installed on the locking block axle pin 43, the distance between the axle pin flange 44 and the locking block axle pin 43 can be slightly greater than the depth of the first hole section 422 (described later) of the mounting hole 420, thereby reducing the possibility that the locking block 42 frictionally drives the axle pin flange 44 and the locking block axle pin 43 to rotate.

[0023] The locking block 42 is provided with a groove 421, the mounting hole 420 is provided in the groove 421, the shaft pin flange 44 is provided in the groove 421, and the thickness of the shaft pin flange 44 is greater than the depth of the groove 421. In this way, the structure of the rotary door lock 40 can be made more compact. In addition, the shaft pin flange 44 is more protruding than the locking block 42, which can reduce the possibility of the locking block 42 contacting the inner door 20 or other structures, so that the locking block 42 is subjected to less resistance when rotating, and at the same time, it can also reduce the possibility of the locking block 42 driving other structures in the rotary door lock 40 (such as the thickening member 46 or the locking screw 45, which will be described later) to rotate when rotating.

[0024] The rotary door lock 40 further includes a locking screw 45, which is passed through the inner door 20 and is threadedly connected to the locking block shaft pin 43 to fix the locking block shaft pin 43 on the inner door 20. Of course, the rotary door lock 40 further includes a thickening member 46, which is passed through the locking screw 45, one end of which abuts against the inner door 20, and the other end abuts against the shaft pin flange 44. The thickening member 46 can raise the locking block 42 (relative to the inner door 20) to adapt to the size of the lock ring 50. On the other hand, during assembly, a force can be applied to the locking block shaft pin 43 and the shaft pin flange 44 toward the outside of the inner door 20, and the locking block shaft pin 43 can be fixed by adding the force applied to the locking block shaft pin 43 by the locking screw 45 toward the inner door 20.

[0025] The thread structure between the locking screw 45 and the locking block shaft pin 43 is different from the thread structure between the locking block shaft pin 43 and the shaft pin flange 44 in at least one of the type, direction, pitch, and thread angle. This can reduce the possibility of the shaft pin flange 44 and the locking screw 45 being separated during the use of the rotary door lock 40. When the shaft pin flange 44 rotates in any direction, causing one of the thread structures to loosen, it will be reacted by the other thread structure to inhibit rotation.

[0026] The size of the thickening member 46 can be larger than that of the shaft pin flange 44 to increase the contact area with the inner door 20, reduce the pressure on the inner door 20, and reduce the possibility of damage to the inner door 20. In addition, the material of the thickening member 46 can be a high temperature resistant material, such as plastic, and the thermal conductivity can be 0.2-0.4 W / (m•K). In this way, the heat transfer inside the incubator 1 can be reduced to a certain extent, reducing the risk of burns to the user when opening and closing the door.

[0027] Generally, a sealing ring 23 is installed at the frame of the small door 21 or the entire inner door 20 to seal the gap between the small door 21 and the outer frame 22, or the gap between the inner door 20 and the box body 10. The rotating handle 41 is generally arranged close to the frame to reduce the distance between the rotating handle 41 and the locking ring 50. Therefore, an escape space 461 can be provided on the outer side of the shaft pin flange 44 to avoid the sealing ring 23.

[0028] The rotary door lock 40 further includes a rotary pin 47 and a torsion spring 48. The rotary pin 47 is disposed on the locking block 42, and the axial direction of the rotary pin 47 is perpendicular to the axial direction of the mounting hole 420. The rotary handle 41 is rotatably disposed on the rotary pin 47. In this way, the rotary handle 41 can be close to the inner door 20 or away from the inner door 20 during the rotation process. For example, when the outer door 30 is closed, it can push the rotary handle 41 to be parallel to the inner door 20, and the rotary handle 41 can be stored, so that the structure of the outer door 30 and the inner door 20 can be more compact. When the outer door 30 is opened, the rotary handle 41 can be rotated in a direction away from the inner door 20, so that the user can more easily hold the rotary handle 41 for rotation operation.

[0029] The torsion spring 48 is provided on the rotating pin 47, and one end of the torsion spring acts on the locking block 42, and the other end acts on the rotating handle 41, so that the rotating handle 41 can automatically rotate toward the side away from the inner door 20 under the action of the torsion spring 48. In this case, when the outer door 30 is closed, the rotating handle 41 can be automatically pushed to rotate toward the side where the inner door 20 is located, and when the outer door 30 is opened, the rotating handle 41 can be rotated toward the side away from the outer door 30 under the action of the torsion spring 48, which is convenient for users to operate.

[0030] The mounting hole 420 may have a first hole section 422 and a second hole section 423. In the projection direction parallel to the axial direction of the mounting hole 420, the projection of the first hole section 422 falls within the projection of the second hole section 423, and the cross section of the second hole section 423 is larger than the cross section of the first hole section 422. Both the first hole section 422 and the second hole section 423 may be circular holes, and the inner diameter of the first hole section 422 may be smaller than the inner diameter of the second hole section 423, so as to facilitate processing.

[0031] The neck 431 of the locking block shaft pin 43 is arranged in the first hole section 422, and the cap 432 is arranged in the second hole section 423. The outer diameter of the cap 432 can be larger than the outer diameter of the inner part, so that the cap 432 plays a limiting role. The rotating pin 47 is penetrated in the locking block 42 in a manner perpendicular to the axial direction of the second hole section 423, and the rotating pin 47 passes through the second hole section 423.

[0032] See also Figure 5 and Figure 6The rotary door lock 40 further includes a rubber plug 49, which is disposed in the second hole section 423 so that the interior of the second hole section 423 is not visible. This can make the rotary door lock 40 more beautiful in appearance. Furthermore, a vent hole 490 is provided on the rubber plug 49. This is because the locking screw 45 and the locking block shaft pin 43 are generally made of metal material, which has good thermal conductivity. Therefore, the heat inside the incubator 1 can easily enter the second hole section 423 through the locking screw 45 and the locking block shaft pin 43, causing the air inside the second hole section 423 to expand, thereby squeezing out the rubber plug 49. The material of the rubber plug 49 can be silicone.

[0033] The rubber plug 49 is provided with an avoidance groove 491 on one side of the second hole section 423 to avoid the rotating pin 47 during installation. This can reduce the depth of the second hole section 423 to a certain extent, improve the space utilization inside the second hole section 423, reduce the thickness of the locking block 42, and make the structure of the inner door 20 and the outer door 30 more compact.
