[0001] The utility model relates to the technical field of cryogenic equipment structures, and particularly relates to a cryogenic equipment with a sliding automatic opening and closing door. Background Art

[0002] At present, with the upgrading of the manufacturing environment, the automation and intelligence of products have become the trend of development. In the field of cryogenic refrigeration equipment, the temperature inside the cryogenic equipment box is -40°C to -86°C, and there is a huge temperature difference between the temperature inside the box and the ambient temperature. If there is a slight gap in the door seal, the cold air inside the box will leak out, resulting in frosting around the mouth of the equipment box body and the door body. Repeatedly opening the door several times will also form ice, which will further affect the airtightness of the box body when closing the door again, and may affect the temperature inside the storage equipment box.

[0003] At the same time, the items stored in cryogenic equipment are generally biological samples. To ensure the safety of the samples, high requirements are imposed on the heat preservation and airtightness of the box body.

[0004] The opening and closing of traditional cryogenic equipment mainly rely on manual handles, which require a great deal of force to operate, have high requirements for operators, and the pressing degree of the door seal is not ideal, affecting the sealing performance and the sensory experience of customers. If the door seal is relatively soft, it may affect the airtightness between the door and the box after closing the door, and there may also be cold leakage.

[0005] Therefore, this application particularly proposes a cryogenic equipment with a sliding automatic opening and closing door to solve the above technical problems. Content of the Utility Model

[0011] The track assembly is connected to the link assembly and is used to restrict the movement of the door body along the track.

[0012] Furthermore, two sets of the link assembly and the track assembly are provided and symmetrically arranged.

[0013] Furthermore, the link assembly includes two sets of crank links arranged in parallel. One end of each crank link is provided with a connecting shaft for connecting to the connecting plate, and the other end is provided with a connecting sleeve shaft for connecting to the door body.

[0014] Furthermore, the track assembly includes a bearing connected to the bottom connecting sleeve shaft, a track plate provided on the bracket, and a track groove opened on the track plate. The bearing is arranged in the track groove for limiting and sliding along a preset track.

[0015] Furthermore, a bending portion is provided in the middle of the track groove for dividing the two ends of the track groove into different length directions.

[0016] Furthermore, it further includes a slide rail arranged in the vertical direction and a slider sliding on the slide rail. The slide rail is provided on the bracket, and the slider is connected to the lifting frame.

Detailed implementation mode

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0033] In the embodiment, refer in detail to Figures 1 to 7 .

[0034] Such as Figure 1 AndFigure 2 As shown in the figure, the present utility model provides a cryogenic device with a sliding automatic opening and closing door, which includes a device box body 1 installed on a bracket 2 and a door body 7 with a seal 701. The door body 7 is used to block the opening of the device box body 1, and further includes:

[0035] A lifting frame 4, which is limited and slidably arranged on the bracket 2 in the vertical direction;

[0036] An electric cylinder 3, which is arranged at the bottom of the bracket 2 and is used to drive the lifting frame 4 to move up and down;

[0037] A connecting rod assembly 6, which is installed on the lifting frame 4 through a connecting plate 5. The connecting rod assembly 6 is connected to the door body 7 and is used to drive the door body 7 to move actively in a constant vertical state during the movement of the connecting rod assembly 6;

[0038] A track assembly 10, which is connected to the connecting rod assembly 6 and is used to limit the movement of the door body 7 along the track.

[0039] Wherein, two sets of the connecting rod assembly 6 and the track assembly 10 are both arranged symmetrically, which can be used to ensure the stability of the door body 7 when moving along the track.

[0040] At this time, by setting an electric cylinder 3 on the cryogenic device to drive the lifting frame 4 to move up and down, and thus cooperating with the connecting rod assembly 6 and the track assembly 10 to complete the automatic opening and closing operation of the door body 7, the precise control and automatic sealing of the door body 7 can be realized, thereby solving the inconvenience and errors brought by the high requirements for the operator in the manual closing method, greatly improving the operation efficiency and safety, and the operation of closing the door with a large pressure mechanical can also ensure the sealing performance of the seal 701 on the door body 7 without frosting, which can not only well improve the safety of the sample due to poor sealing and leakage, but also well improve the use experience of the operator.

[0041] It should be noted that the seal 701 here generally adopts a sealing rubber strip in the prior art, and the electric cylinder 3 adopts any electric cylinder or electro-control air cylinder in the prior art. Of course, in the actual use process of this application, the above structures can be reasonably replaced with the structures disclosed in the prior art under the condition of meeting the actual use requirements.

[0042] In a further specific implementation, as Figure 4 and Figure 5 shown, the connecting rod assembly 6 includes two sets of crank connecting rods 601 arranged in parallel. One end of the crank connecting rod 601 is provided with a connecting shaft 602 for connecting with the connecting plate 5, and the other end of the crank connecting rod 601 is provided with a connecting sleeve shaft 603 for connecting with the door body 7.

[0043] The crank connecting rod 601 here adopts a conventional connecting rod structure.

[0044] At this time, by using the connection of the link assembly 6 and the track assembly 10 during the lifting process of the door body 7 and the lifting frame 4, the dual movement modes of the linear lifting and horizontal sliding of the door body 7 can be realized, thereby ensuring that sufficient uniform pressure is applied to the seal 701 of the door body 7 during the closing process, effectively enhancing the sealing performance, preventing frosting, and avoiding sample damage or contamination caused by poor sealing.

[0045] As Figure 6 and Figure 7 shown, the track assembly 10 includes a bearing 1001 connected to the bottom connecting sleeve shaft 603, a track plate 1002 provided on the bracket 2, and a track groove 1003 opened on the track plate 1002. The bearing 1001 is arranged in the track groove 1003 for limited sliding along a preset track.

[0046] At this time, by arranging the bearing 1001 to slide in the track groove 1003 in the movement track of the door body 7, the movement friction can be significantly reduced and the operation accuracy can be improved, thereby ensuring smooth opening and closing of the door body 7, reducing energy consumption and wear, and ultimately achieving the effects of improving the service life of the equipment and the safety of sample storage.

[0047] In addition, a bending portion 1004 is further provided in the middle of the track groove 1003 for dividing the two ends of the track groove 1003 into two different length directions, vertical and horizontal.

[0048] At this time, by providing the bending portion 1004 in the middle of the track groove 1003, it is possible to conveniently, smoothly and quickly guide the door body 7 to change the moving direction, thereby not only realizing a smooth transition of the movement track switching of the door body 7, but also ensuring a tight pressing of the door gap during the horizontal movement stage, thus achieving an excellent sealing effect, maintaining the stability of the ultra-low temperature environment, and ensuring the long-term safe storage of the sample.

[0049] In summary, during the use process, the door body 7 can be opened and closed by sliding up and down along the track through the track assembly 10. During the closing process, the door body 7 moves upward under the drive of the electric cylinder 3. During the movement, the seal 701 of the door body 7 does not contact the equipment box body 1. When the door body 7 moves to the opening directly opposite the equipment box body 1, by using the movable connection control of the link assembly 6, the bearing 1001 in the track groove 1003 moves horizontally under the drive of the electric cylinder 3, driving the door body 7 to move horizontally, and the door body 7 presses the equipment box body 1 through the seal 701, thereby realizing sealing.

[0050] In a specific embodiment, as Figure 3 shown, a slide rail 8 arranged in the vertical direction and a slider 9 sliding on the slide rail 8 are provided on the ultra-low temperature equipment. The slide rail 8 is provided on the bracket 2, and the slider 9 is connected to the lifting frame 4.

[0051] At this time, by setting the vertical slide rails 8 and the corresponding sliders 9 on the bracket 2, the stable lifting of the lifting frame 4 can be ensured, enhancing the stability and durability of the entire door opening and closing system, making the equipment operation more reliable, reducing operation interruptions caused by mechanical failures, and ultimately improving the service life of the overall equipment.

[0052] Among them, two sets of slide rails 8 are symmetrically arranged on the bracket 2, and two sets of sliders 9 are correspondingly slid on the two sets of slide rails 8.

[0053] At this time, it can be summarized that the connecting rod assembly 6, the track assembly 10, as well as the slide rails 8 and the sliders 9 all adopt a double-group symmetrical design. This not only ensures the balance and synchronization of the opening and closing actions of the door body 7, but also improves the load-bearing capacity of the equipment and the stability of movement, further strengthening the reliability of the sealing of the door body 7 and ensuring the efficiency and safety of the equipment during frequent use.

[0054] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.

[0055] In addition, it should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, then the directional indications are only used to explain the relative position relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0056] In addition, the meaning of "and / or" appearing throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, or solution B, or the solution where A and B are satisfied simultaneously. In addition, in the embodiments of the present invention, "a plurality" means two or more. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.
