[0042] The core of the utility model is to provide a door device, which can prevent the door from sliding back when rotating.

[0046] An embodiment of the utility model provides a door device, including a main body 1, a supporting member 2, a door 3 and an elastic check member 4, wherein the supporting member 2 is slidably arranged on the main body 1, and the supporting member 2 is provided with a limiting portion 21; the door 3 is rotatably arranged on the supporting member 2; the elastic check member 4 is arranged at a position of the main body 1 corresponding to the sliding end position of the supporting member 2, and is used for being squeezed by the door 3 when the supporting member 2 slides to the sliding end position 7, and being released after the door 3 rotates, and after the elastic check member 4 is released, it stops and limits the limiting portion 21.

[0047] When opening the door 3, first slide the door 3 and the supporting member 2 out together. When the supporting member 2 slides to the sliding end position 7, it indicates that the door 3 has slid into place. At this time, the door 3 squeezes the elastic check member 4, causing the elastic check member 4 to produce elastic deformation and have elastic restoring force; then, the door 3 is rotated open relative to the supporting member 2. When the door 3 rotates away from the sliding end position 7 of the supporting member 2, the elastic check member 4 rebounds and resets, abutting against the limit portion 21 to stop the supporting member 2 and prevent the door 3 from sliding back during the rotation process, that is, the door 3 cannot translate back when rotating open.

[0048] When closing the door 3, the door 3 is rotated relative to the supporting member 2 to the sliding end position 7. At this time, the door 3 squeezes the elastic check member 4, causing the elastic check member 4 to produce elastic deformation and have elastic restoring force; after the elastic check member 4 is squeezed, the limiting portion 21 can be given way, so that the door 3 and the supporting member 2 can slide together, so that the door 3 can retreat to the position before opening.

[0049] It should be noted that, in order to prevent the elastic check member 4 from being in a squeezed state when the door 3 is closed, in some embodiments, the elastic check member 4 extends to the sliding end position 7 of the supporting member 2 in a natural state. That is, when the door 3 and the supporting member 2 slide in translation and return to the position where the door 3 is closed, the elastic check member 4 rebounds to its original position and extends to the sliding end position 7 of the supporting member 2, so that the elastic check member 4 is squeezed by the door 3 when the door 3 and the supporting member 2 slide in translation to the sliding end position 7 when the door 3 is opened next time. In this case, the elastic check member 4 is always in a natural non-squeezed state when the door 3 is closed, which is conducive to improving the service life and reliability of the elastic check member 4.

[0050] In addition, it should be noted that the specific structure of the elastic check member 4 is not limited in this embodiment, as long as the elastic check member 4 is elastic, can be rebound into the sliding end position 7 of the support member 2 in a natural state, and can be withdrawn from the sliding end position 7 of the support member 2 under the extrusion of the door 3. For example, the elastic check member 4 can be a spring with a preset structure, or can be a combination of an elastic member (such as a spring) and a stop block. The elastic check member 4 can be popped up left and right, or up and down, as long as it can play a check role on the limit portion 21.

[0051] Furthermore, the present embodiment does not limit the specific structure of the limiting portion 21 . For example, the limiting portion 21 may be a protrusion protruding from the bottom of the supporting member 2 .

[0052] In order to improve the smoothness of the movement of the door 3 when rotating, in some embodiments, the door 3 is provided with a stopper 31, and the supporting member 2 is provided with a stopper groove 22 for the stopper 31 to slide, so as to limit the rotation of the stopper 31. That is, when the door 3 rotates, the stopper 31 slides along the stopper groove 22, and the stopper groove 22 limits the movement trajectory of the stopper 31 when the door 3 rotates, so that the movement of the door 3 when rotating to open or close is smoother. It should be noted that the shape of the stopper groove 22 is determined by the movement trajectory of the stopper 31 when the door 3 rotates.

[0053] It should be noted that the present embodiment does not limit the specific structure of the limiting member 31 . In some embodiments, the limiting member 31 is a limiting column.

[0054] Furthermore, in order to limit the angle when the door 3 rotates to open, in some embodiments, both ends of the limiting groove 22 are closed ends to limit the extreme rotation angle of the limiting member 31. That is to say, the two closed ends of the limiting groove 22 serve as two stop points. When the door 3 rotates to open, when the limiting member 31 moves to one end of the limiting groove 22 and abuts against the end, it indicates that the door 3 is fully rotated and opened, and it will not be possible to continue to open the door 3 to a larger angle; when the door 3 rotates to close, the limiting member 31 moves to the other end of the limiting groove 22 and abuts against the other end, which indicates that the door 3 is fully rotated and closed; therefore, the angle between the two ends of the limiting groove 22 can be used to limit the opening angle of the door 3. For example, in some embodiments, the limiting groove 22 is an arc groove, and the angle between the two ends of the limiting groove 22 is 90°, that is, the door 3 can be opened 90 degrees.

[0055] In addition, in order to make the support member 2 and the door 3 slide more smoothly, in some embodiments, the main body 1 is provided with a guide bar 11, which is used to slide and limit the first side of the limiter 31 when the support member 2 slides; when the support member 2 slides to the sliding end position 7, the limiter 31 slides to the end of the guide bar 11. In other words, when the support member 2 and the door 3 slide relative to the main body 1, the limiter 31 slides along the guide bar 11, and the guide bar 11 limits the movement direction of the limiter 31 to ensure the correctness of the translation and sliding direction of the door 3 and the support member 2, and make the movement of the door 3 and the support member 2 more stable. In addition, when the guide bar 11 stops and limits the limiter 31, the door 3 can also be prevented from rotating, that is, it is ensured that the door 3 does not rotate when sliding. When the supporting member 2 slides to the sliding end position 7, the limiting member 31 slides to the end of the guide bar 11. At this time, the stopping and limiting effect of the guide bar 11 on the limiting member 31 disappears, so that the door 3 can rotate.

[0056] Furthermore, in some embodiments, when the guide bar 11 slides and limits the limit member 31, the second side of the limit member 31 abuts against the first end of the limit groove 22, so that the first end of the limit groove 22 is used to limit the second side of the limit member 31, and the second side of the limit member 31 and the first side of the limit member 31 are opposite sides. That is to say, when the door 3 and the supporting member 2 translate and slide together, the first side of the limit member 31 contacts the guide strip 11, and the second side of the limit member 31 contacts the first end of the limit groove 22. The first ends of the guide strip 11 and the limit groove 22 are respectively located on both sides of the limit member 31, forming a state in which the limit member 31 is clamped on both sides, so that the limit member 31 can only move along the length direction of the guide strip 11 but cannot swing, thereby limiting the door 3 to only translate and slide but not swing or rotate, etc., ensuring that the door 3 and the supporting member 2 move more smoothly. Combined with the effect of the elastic check member 4, the door 3 cannot slide back when rotating, so that the door opening action is performed in steps (that is, first slide to pull the door out, and then rotate to open the door), and the door closing action is also performed in a distributed manner, making it safer to open and close the door.

[0057] In some embodiments, the second end of the limiting groove 22 is used to limit the limiting member 31 to define the extreme rotation angle of the door 3 .

[0058] In addition, in order to reduce friction during the translation and sliding of the door 3 and the supporting member 2, in some embodiments, the stopper 31 is provided with a first bearing 311 or a ball for contacting the guide bar 11. That is, in this embodiment, by adding the first bearing 311 or the ball, the sliding friction between the stopper 31 and the guide bar 11 is changed into rolling friction, thereby reducing friction and making the translation and sliding of the door 3 and the supporting member 2 smoother.

[0059] Further, in order to ensure that the door 3 and the supporting member 2 can slide in translation more smoothly, in some embodiments, the body 1 is provided with an upper sliding assembly and a lower sliding assembly 12, the supporting member 2 is connected to the lower sliding assembly 12, the door 3 is connected to an upper cantilever 5, and the upper cantilever 5 is connected to the upper sliding assembly. That is to say, in this embodiment, the upper sliding assembly and the lower sliding assembly 12 are used to limit the upper cantilever 5 and the supporting member 2 to slide in translation at the same time, so as to ensure that the door 3 and the supporting member 2 can slide in translation more smoothly. In addition, the sliding stroke of the door 3 and the supporting member 2 can be limited by the structural and dimensional characteristics of the upper sliding assembly and the lower sliding assembly 12. It should be noted that in this embodiment, the specific structure of the upper sliding assembly and the lower sliding assembly 12 is not limited, and the structures of the upper sliding assembly and the lower sliding assembly 12 can be the same or different. The upper sliding assembly and the lower sliding assembly 12 can be any one of a linear guide, a linear bearing, a shaft 61 and a sleeve 62, and a sliding bearing.

[0060] In addition, in some embodiments, the body 1 includes a first space and a second space separated from each other, the second space is a bottom open space, and the lower sliding component 12 is arranged in the second space. It should be noted that the first space is a working space with a door device, and is an interactive movement space of the internal modules of the door device, which can have the properties of sealing and heat preservation. In this embodiment, the body 1 is divided into the first space and the second space, and the two are separated from each other, that is, the first space and the second space do not affect each other; the lower sliding component 12 is arranged in the second space to avoid the lower sliding component 12 from affecting the first space when sliding, so as to ensure the performance of the first space, such as sealing and heat preservation characteristics.

[0061] In addition, in order to ensure the smoothness of the rotating door 3, in some embodiments, the support member 2 and the upper cantilever 5 are respectively connected to the door 3 through the rotating assembly 6. The rotating assembly 6 includes a shaft 61, a sleeve 62, a second bearing 63, a pre-load ring 64 and a bearing cover 65. The sleeve 62 is sleeved on the outer periphery of the shaft 61; and the second bearing 63 is connected between the sleeve 62 and the shaft 61, and the pre-load ring 64 is pressed against the end of the second bearing 63; the bearing cover 65 is connected to the second bearing 63 and presses the pre-load ring 64. It should be noted that the second bearing 63 is used in pairs, for example, the second bearing 63 is an angular contact bearing. In this embodiment, the bearing cover 65 and the pre-load ring 64 are used to press the second bearing 63, which plays a role in adjusting the matching clearance between the paired second bearings 63, and ensures the rigid connection when the door 3 moves. In addition, the support member 2 and the upper cantilever 5 are rotatably connected to the door 3 through the rotating assembly 6, respectively, to ensure that the upper cantilever 5 and the support member 2 move synchronously when the door 3 and the support member 2 slide in translation, to avoid the door 3 from tilting or skewing in a parallelogram-like manner when the door 3 slides in translation, and to ensure the smoothness of the rotation of the door 3. At the same time, the use of the paired second bearings 63 not only plays a role in rotation, but also plays a role in bearing weight.

[0062] In addition, it should be noted that in the above embodiments, the specific structure of the body 1 is not limited, and the body 1 can be any cabinet as long as it needs a door 3. In some embodiments, the body 1 includes a fully automatic microbial blood culture instrument device body or a control cabinet. The specific structure of the fully automatic microbial blood culture instrument device body and the control cabinet can be found in the prior art, and will not be repeated herein.

[0063] It should also be noted that, in this specification, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0064] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0065] The above is a detailed introduction to the door device provided by the utility model.
