Description

Technical Field

[0001] The present invention relates to the field of test experiments, and specifically to a sliding sealed hatch and a nitrogen chamber transition chamber. Background Art

[0002] In traditional laboratories, the daily work of synthetic experimenters mainly involves route design and synthesis work, that is, implementing chemical reaction experiments step by step according to the designed synthesis process. In addition, to complete a complete reaction, synthetic experimenters need to do a lot of preparatory work before and post-treatment work, such as the preparation of materials, experimental utensils and equipment, and also need to conduct a series of operations such as sampling and testing, post-treatment and purification for each reaction, and timely record and update the experimental process and data information. The whole process is time-consuming and laborious, and a large number of repetitive simple operations occupy the precious time of synthetic experimenters.

[0003] The emergence of a management platform for realizing the informatization and automation of modern laboratories and composite robots has brought many benefits to the management of modern comprehensive laboratories, replacing the high-density workload in the laboratory. Its application greatly improves the overall business ability of the laboratory, improves work efficiency, reduces the labor intensity of researchers, prevents product safety risks, and reduces costs. Bid farewell to the situation where test experiments almost entirely rely on manual operation, with cumbersome steps, long time span, and certain uncertainties in the implementation by experimental personnel.

[0004] In order to avoid the influence of oxygen and moisture in the air on the reaction during the experiment in reagent bottles, the present application proposes a sliding sealed hatch and a nitrogen chamber transition chamber to achieve the sealing function without interfering with external moving devices. Summary of the Invention

[0005] In order to solve the technical problems that the hatch of the existing transition chamber interferes with external moving devices and has poor sealing performance, the present invention provides a sliding sealed hatch, which solves the above technical problems.

[0006] The technical solution adopted by the present invention to solve its technical problems is:

[0007] The present invention provides a sliding sealed hatch door for sealing a sealed cabin, comprising: a door panel, the door panel being slidably fitted on the outer cabin surface at the open end of the sealed cabin; a sealing assembly, the sealing assembly being arranged at the open end of the outer cabin surface, and the sealing ring of the sealing assembly protruding from the outer cabin surface; a pressing assembly, the pressing assembly being arranged on the sealed cabin, the pressing rod of the pressing assembly being movably connected to the sealed cabin, when the door panel moves to the closed position, the pressing rod rotates to push the door panel to be pressed on the outer cabin surface; an elastic pulley assembly, the elastic pulley assembly comprising a movable rod, a pulley and a first elastic member, one end of the movable rod being hinged to the side of the door panel, the other end of the movable rod being connected with the pulley, the pulley surface of the pulley being fitted on the outer cabin surface, and the first elastic member being arranged between the rod body of the movable rod and the door panel to reset the movable rod.

[0008] For the sliding sealed hatch door of the present application, the door panel is movably arranged on the outer cabin surface at the open end of the sealed cabin. When the door panel moves to the closed position, the pressing rod of the pressing assembly presses the door panel on the outer cabin surface of the sealed cabin and cooperates with the sealing assembly to realize the sealing of the sealed cabin. At the same time, an elastic pulley assembly is arranged between the door panel and the outer cabin surface to realize the movement of the door panel towards the outer cabin surface. Specifically, in the opening and closing state, under the action of the first elastic member, the movable rod protrudes from the door panel so that the pulley surface of the pulley at this end is fitted on the outer cabin surface, thus facilitating the sliding of the door panel. When closing, the first elastic member contracts, and the movable rod and the pulley on the movable rod are received on the side of the door panel, enabling the door panel to move towards the outer cabin surface and fit on the sealing assembly to realize the sealing of the sealed cabin. That is to say, the elastic pulley assembly does not affect the sliding of the door panel on the outer cabin surface on the one hand, and does not interfere with the fitting movement of the door panel towards the outer cabin surface on the other hand, thereby realizing the sealing effect on the premise that the opening and closing of the sealed cabin do not interfere with the external moving device.

[0009] Further, the first end of the pressing rod is hinged to the sealed cabin. At the same time, a pressing claw is formed at the first end of the pressing rod, and an enveloping groove that envelops the edge of the door panel is formed between the pressing claw and the outer cabin surface.

[0010] Further, the pressing assembly further comprises a pressing cylinder arranged on the sealed cabin and a pushing member connected to the piston rod of the pressing cylinder. The pressing cylinder and the pushing member are arranged at the second end of the pressing rod. When the pushing member moves towards the second end of the pressing rod, it pushes the pressing rod to rotate so that the pressing claw abuts against the door panel.

[0011] Further, the inclined surface of the pushing member in contact with the pressing rod is formed as a pushing surface. At the same time, a movable guide wheel is arranged at the second end of the pressing rod, and the guide wheel is fitted on the pushing surface.

[0012] Further, it further includes a locking assembly disposed on the side of the sealed chamber. The locking assembly includes: a connecting block connected to the side of the sealed chamber; a locking rod, the middle section of the locking rod is hinged to the connecting block, the first end of the locking rod forms a locking hook for locking the door panel after being bent once, and a connecting rod for driving the locking rod is hinged to the second end of the locking rod; a connecting rod, the connecting rod is limited to move linearly within the connecting block; a second elastic member, the second elastic member is disposed on the connecting block to reset the connecting rod; a locking cylinder, the cylinder body of the locking cylinder is disposed on the connecting block, and a wedge block for pushing the connecting rod to move is fixedly connected to the piston rod of the locking cylinder.

[0013] Further, a transverse force-bearing member is fixedly connected to the rod body of the connecting rod, and the force-bearing member is fitted on the wedge surface of the wedge block.

[0014] Further, the second elastic member is a torsion spring disposed at the hinge joint of the connecting rod and the locking rod.

[0015] Further, a plurality of locking grooves for accessing the locking hook are formed on the door panel.

[0016] Further, a blocking piece is disposed at a position where the door panel is away from the sealed chamber. A containing groove is formed on the rod body of the movable rod of the elastic pulley assembly, the opening of the containing groove faces the blocking piece, the first elastic member is disposed in the containing groove, one end of the first elastic member abuts against the bottom of the containing groove, and the other end of the first elastic member abuts against the blocking piece.

[0017] On the other hand, the present invention further provides a nitrogen chamber transition chamber, including: a sealed chamber configured with two open ends, one of the open ends communicates with the outside, and the other open end communicates with the nitrogen chamber; the above-mentioned sliding sealed chamber door, and two groups of the sliding sealed chamber doors are respectively disposed at the two open ends.

[0018] When the nitrogen chamber transition chamber of the present application is in use, first open the sliding sealed chamber door at the place communicating with the outside. After placing the reaction bottle into the inner cavity of the sealed chamber, close the sliding sealed chamber door at the place communicating with the outside. The inner cavity of the sealed chamber is evacuated by an external exhaust fan, and then nitrogen is filled into the inner cavity by an external gas filling machine. After the nitrogen is filled, the sliding sealed chamber door at the place communicating with the nitrogen chamber is opened, the reagent bottle is placed into the nitrogen chamber, the reaction bottle is opened, and subsequent reaction tests are carried out on the reagent in the reagent bottle, so as to ensure that the reagent in the reagent bottle does not contact oxygen and water in the air, and thus better experimental results can be obtained.

[0019] Based on the above technical solutions, the technical effects that the present invention can achieve are:

[0020] For the sliding sealed hatch door of the present application, the door panel is movably arranged on the outer hatch surface at the opening end of the sealed chamber. When the door panel moves to the closed position, the pressing rod of the pressing component presses the door panel against the outer hatch surface of the sealed chamber and cooperates with the sealing component to achieve the sealing of the sealed chamber. At the same time, an elastic pulley component is arranged between the door panel and the outer hatch surface to enable the movement of the door panel towards the outer hatch surface. Specifically, when in the open and closed states, under the action of the first elastic member, the movable rod protrudes from the door panel such that the pulley surface of the upper pulley at this end fits on the outer hatch surface, thereby facilitating the sliding of the door panel. When closed, the first elastic member contracts, and the movable rod and the pulley on the movable rod are received on the side of the door panel, enabling the door panel to move towards the outer hatch surface and fit on the sealing component to achieve the sealing of the sealed chamber. That is to say, the elastic pulley component does not affect the sliding of the door panel on the outer hatch surface on the one hand, and does not interfere with the fitting movement of the door panel towards the outer hatch surface on the other hand, thus achieving the sealing effect on the premise that the opening and closing of the sealed chamber do not interfere with the external moving device.

[0021] For the nitrogen chamber transition chamber of the present application, during use, first open the sliding sealed hatch door at the connection with the outside. After placing the reaction flask into the inner cavity of the sealed chamber, close the sliding sealed hatch door at the connection with the outside. Then, use an external exhaust fan to evacuate the inner cavity of the sealed chamber, and then use an external inflator to fill the inner cavity with nitrogen. After the nitrogen is filled, open the sliding sealed hatch door at the connection with the nitrogen chamber, place the reagent flask into the nitrogen chamber, open the reaction flask, and conduct subsequent reaction tests on the reagent in the reagent flask, thereby ensuring that the reagent in the reagent flask does not contact oxygen and water in the air, and thus obtaining better experimental results.

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.

[0032] Unless otherwise specifically stated, the relative arrangements of the components and steps set forth in these embodiments, numerical expressions, and numerical values do not limit the scope of the present invention. At the same time, it should be understood that for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and devices should be regarded as part of the authorized specification. In all the examples shown and discussed here, any specific value should be interpreted as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0033] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation terms such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description. Without contrary explanation, these orientation terms do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation.

[0035] In addition, it should be noted that using words such as "first", "second", etc. to limit components is only for the convenience of distinguishing the corresponding components. Without additional statement, the above words have no special meaning. Therefore, it should not be construed as a limitation on the protection scope of the present invention.

[0036] Currently, the experimental process of the reagent needs to be carried out in a nitrogen environment without water and oxygen. To ensure that the whole process is in a nitrogen environment without water and oxygen, the current practice is to first set up a nitrogen chamber, and configure a sealing chamber for transition at the connection between the nitrogen chamber and the outside. There are also multiple movable devices outside the sealing chamber, such as manipulators. If the sealing chamber is set as an opening and closing door with hinge cooperation, on the one hand, it is easy to interfere with the external movable devices, and on the other hand, the sealing performance is difficult to guarantee. Therefore, a hatch door that does not interfere with the external movable devices and can achieve the sealing function is needed.

[0037] Such as Figure 1-7As shown in the figure, the present application proposes a sliding sealed hatch for sealing the sealed cabin 1, which includes a door panel 2, a sealing component 11, a pressing component 3 and an elastic pulley component 4. The door panel 2 is slidably fitted on the outer cabin surface at the opening end of the sealed cabin 1. Specifically, a limiting guide rail 12 can be provided on the outer cabin surface of the sealed cabin 1. The sealing component 11 is configured at the opening end of the outer cabin surface, and the sealing ring of the sealing component 11 protrudes from the outer cabin surface. Specifically, the sealing component 11 includes two sealing rings arranged in sequence at the opening end of the outer cabin surface, and both sealing rings are embedded in the sealed cabin 1. The pressing component 3 is configured on the sealed cabin 1, and the pressing rod 31 of the pressing component 3 is movably connected to the sealed cabin 1. When the door panel 2 moves to the closed position, the pressing rod 31 rotates to push the door panel 2 to press on the outer cabin surface. The elastic pulley component 4 includes a movable rod 41, a pulley 42 and a first elastic member 43. One end of the movable rod 41 is hinged to the side of the door panel 2, the other end of the movable rod 41 is connected with the pulley 42, and the pulley surface of the pulley 42 is fitted on the outer cabin surface. The first elastic member 43 is configured between the rod body of the movable rod 41 and the door panel 2 to reset the movable rod 41.

[0038] For the sliding sealed hatch of the present application, the door panel 2 is movably configured on the outer cabin surface at the opening end of the sealed cabin 1. When the door panel 2 moves to the closed position, the pressing rod 31 of the pressing component 3 presses the door panel 2 on the outer cabin surface of the sealed cabin 1 and cooperates with the sealing component 11 to achieve the sealing of the sealed cabin 1. At the same time, an elastic pulley component 4 is configured between the door panel 2 and the outer cabin surface to realize the movement of the door panel 2 towards the outer cabin surface. Specifically, in the open and closed state, under the action of the first elastic member 43, the movable rod 41 protrudes from the door panel 2 so that the pulley surface of the pulley 42 at this end is fitted on the outer cabin surface, thus facilitating the sliding of the door panel 2. When closed, the first elastic member 43 contracts, and the movable rod 41 and the pulley 42 on the movable rod 41 are received on the side of the door panel 2, enabling the door panel 2 to move towards the outer cabin surface and fit on the sealing component 11 to achieve the sealing of the sealed cabin 1. That is to say, the elastic pulley component 4 does not affect the sliding of the door panel 2 on the outer cabin surface on the one hand, and does not interfere with the fitting movement of the door panel 2 towards the outer cabin surface on the other hand, thus achieving the sealing effect on the premise that the opening and closing of the sealed cabin 1 do not interfere with the external moving device.

[0039] In a specific embodiment of the present application, the first end of the pressing rod 31 of the pressing component 3 is hinged to the sealed cabin 1. At the same time, a pressing claw 32 is formed at the first end of the pressing rod 31, and an enveloping groove 33 that envelopes the edge of the door panel 2 is formed between the pressing claw 32 and the outer cabin surface. Specifically, a convex block is provided at the edge of the sealed cabin 1, and the first end of the pressing rod 31 is hinged to the convex block. At the same time, in order to make the pressing claw 32 better press on the door panel 2, a flange 22 that cooperates with the pressing claw 32 is configured at the edge of the door panel 2. In this way, when the door panel 2 enters the enveloping groove 33, the pressing claw 32 can firmly grasp the door panel 2 and perform the pressing action.

[0040] In a specific embodiment of the present application, a blocking piece is arranged at a position on the door panel 2 away from the sealing chamber 1. A receiving groove 411 is formed on the rod body of the movable rod 41 of the elastic pulley assembly 4. The opening of the receiving groove 411 faces the blocking piece. The first elastic member 43 is arranged in the receiving groove 411. One end of the first elastic member 43 abuts against the bottom of the receiving groove 411, and the other end of the first elastic member 43 abuts against the blocking piece. Specifically, the first elastic member 43 can be selected as a spring. In the free state, the first elastic member 43 pops the movable rod 41 towards the outer cabin surface. When the door panel 2 is pressed and closed by the pressing claw 32, the first elastic member 43 contracts so that the movable rod 41 and the pulley 42 on the movable rod 41 are received on the side surface of the door panel 2.

[0041] To enable the door panel 2 to move better in the limit guide rail 12, a movable wheel 23 is further arranged on the side surface of the door panel 2, and the movable wheel 23 is movably engaged with the inner wall of the limit guide rail 12.

[0042] In a specific embodiment of the present application, the action of the pressing rod 31 is driven by a pressing cylinder 34. The cylinder body of the pressing cylinder 34 is arranged on the sealing chamber 1, specifically at the second end of the pressing rod 31. A pushing member 35 is connected to the piston rod of the pressing cylinder 34. When the pushing member 35 moves towards the second end of the pressing rod 31, it pushes the pressing rod 31 to rotate so that the pressing claw 32 abuts against the door panel 2 and presses and closes the door panel 2.

[0043] Further, the inclined surface where the pushing member 35 contacts the pressing rod 31 forms a pushing surface 351. At the same time, a movable guide wheel 36 is arranged at the second end of the pressing rod 31, and the guide wheel 36 is engaged with the pushing surface 351. Specifically, the pushing member 35 moves linearly, and the pushing surface 351 of the pushing member 35 pushes the guide wheel 36. Since the first end of the pressing rod 31 is hinged to the convex block, when the guide wheel 36 at the second end of the pressing rod 31 is pushed, the pressing claw 32 at the first end of the pressing rod 31 will perform a pressing action towards the door panel 2.

[0044] To achieve the locking of the door panel 2 at two extreme positions, the sliding sealing cabin door of the present application further includes a locking assembly 5 arranged on the side of the sealing chamber 1. The locking assembly 5 includes a connecting block 51, a locking rod 52, a connecting rod 54, a second elastic member 55, and a locking cylinder 56. The connecting block 51 is connected to the side of the sealing chamber 1. The middle section of the locking rod 52 is hinged to the connecting block 51. The first end of the locking rod 52 forms a locking hook 53 for locking the door panel 2 after being bent once. The second end of the locking rod 52 is hinged with a connecting rod 54 for driving the locking rod 52. The connecting rod 54 is limited to move linearly within the connecting block 51. The second elastic member 55 is arranged on the connecting block 51 to reset the connecting rod 54. The cylinder body of the locking cylinder 56 is arranged on the connecting block 51, and a wedge block 57 for pushing the connecting rod 54 to move is fixedly connected to the piston rod of the locking cylinder 56.

[0045] Specifically, as the piston rod of the locking cylinder 56 moves, the wedge block 57 on the movable rod 41 pushes the connecting rod 54 to move. The hinged end of the pushed connecting rod 54 moves away from the door panel 2. Since the middle section of the locking rod 52 hinged to the connecting rod 54 is hinged to the connecting block 51, when the second end of the locking rod 52 is driven by the connecting rod 54 to move away from the door panel 2, the locking hook 53 at the first end of the locking rod 52 will move towards the door panel 2 to lock the door panel 2. Specifically, a plurality of locking grooves 21 for receiving the locking hook 53 are formed on the door panel 2. The locking hook 53 enters the locking groove 21 to limit and lock the door panel 2. Correspondingly, a relief hole is formed at a position on the guide rail opposite to the locking hook 53 so that the locking hook 53 can enter the locking groove 21.

[0046] Further, a transverse force-bearing member 541 is fixedly connected to the rod body of the connecting rod 54. The force-bearing member 541 is fitted on the wedge surface of the wedge block 57. That is, the wedge block 57 pushes the connecting rod 54 by pushing the force-bearing member 541.

[0047] In a specific embodiment of the present application, the second elastic member 55 is preferably a torsion spring disposed at the hinge joint of the connecting rod 54 and the locking rod 52. In the free state, the torsion spring enlarges the included angle between the connecting rod 54 and the locking rod 52, so that the hinged end of the connecting rod 54 approaches the door panel 2, thereby driving the second end of the locking rod 52 to move towards the door panel 2. Since the middle section of the locking rod 52 is hinged to the connecting block 51, when the second end of the locking rod 52 approaches the door panel 2, the locking hook 53 will be taken out of the door panel 2 to release the locked state. Of course, the second elastic member 55 can also be selected as a tension spring or a spring disposed at one end of the connecting rod 54, as long as it can make the hinged end of the connecting rod 54 in the free state approach the door panel 2 and release the locked state of the door panel 2.

[0048] On the other hand, the present application also provides a nitrogen chamber transition cabin, which includes a sealed cabin 1 and two sets of the above-mentioned sliding sealed cabin doors. The sealed cabin 1 is provided with two open ends, one of the open ends is communicated with the outside, and the other open end is communicated with the nitrogen chamber. The two sets of sliding sealed cabin doors are respectively arranged at the two open ends.

[0049] When the nitrogen chamber transition cabin of the present application is in use, first open the sliding sealed cabin door at the connection with the outside. After placing the reaction bottle into the inner cavity of the sealed cabin 1, close the sliding sealed cabin door at the connection with the outside. Then, use an external exhaust fan to evacuate the inner cavity of the sealed cabin 1, and then use an external inflator to fill nitrogen into the inner cavity. After the nitrogen is filled, open the sliding sealed cabin door at the connection with the nitrogen chamber, place the reagent bottle into the nitrogen chamber, open the reaction bottle and perform subsequent reaction tests on the reagent in the reagent bottle, so as to ensure that the reagent in the reagent bottle does not contact oxygen and water in the air, thereby obtaining better experimental results.

[0050] It should be understood that the specific embodiments described above are only used to explain the present invention and are not used to limit the present invention. Obvious changes or variations derived from the spirit of the present invention are still within the protection scope of the present invention.
