Description

Technical Field

[0001] This utility model relates to the field of glove box sealing technology, specifically a sealing door for glove boxes and ovens. Background Technology

[0002] Vacuum glove boxes typically have an oven connected to their side. The oven is used to heat materials, and during production, materials often need to be transferred between the two chambers. The oven has an inner door and an outer door. The inner door is installed at the connection between the oven and the glove box, and the outer door is installed at the opposite end of the inner door. When the inner door is open, the outer door must be closed, and vice versa, to ensure the vacuum glove box is sealed. The inner door, as a sealing door, needs to have reliable sealing performance to prevent contaminants such as moisture and oxygen from the external environment from entering, while also preventing the heat and volatile substances inside the oven from affecting the atmosphere inside the glove box.

[0003] Existing sealed doors of this type mostly use a hinged opening structure. Hinged sealed doors occupy a large space, and their opening and closing trajectories are complex, making them unsuitable for automated control in compact layouts. Furthermore, there is a problem of inconsistency between the sealing clamping force and the driving force, making it difficult to achieve a good seal while ensuring smooth operation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] See Figures 1-2 This embodiment discloses a sealing door for a glove box and an oven, including a mounting plate 3 fixedly connected to the end face of the oven 1 and an inner door assembly 4 connected to the mounting plate 3. The mounting plate 3 is fixed to the end face of the oven 1 by means of bolt connection or welding, and is simultaneously connected to the box panel 2 of the glove box. A gasket or other sealing material is provided between the mounting plate 3 and the end face of the oven 1 to ensure the airtightness of the connection between the two.

[0024] like Figure 2As shown, the mounting plate 3 has a U-shaped opening 31 at its center, connecting the glove box and the oven 1 cavity. The upper and lower ends of the U-shaped opening 31 extend horizontally to the far end. This structure serves two purposes: firstly, it connects to the glove box panel 2; secondly, it provides a precise installation and guiding reference for the inner door assembly 4, and also reserves the necessary travel space for its horizontal movement. It should be noted that the outline area of ​​the U-shaped opening 31 is constructed to be slightly larger than the opening area of ​​the oven 1 end face, so that the structure of the mounting plate 3 and the oven 1 end face cooperate to form an annular abutment part 32, which serves as the final sealing and pressing surface when the inner door assembly 4 is closed.

[0025] Combination Figure 3 and Figure 4 The inner door assembly 4 includes an inner door body 41 and an inner door carriage connecting plate 42, which are arranged parallel and spaced apart in the front-to-back direction (i.e., perpendicular to the plane of the mounting plate 3). The inner door body 41 is located on the side closer to the oven 1, while the inner door carriage connecting plate 42 is located on the side closer to the glove box (away from the oven 1). In this embodiment, the shape of the inner door body 41 is adapted to the abutment portion 32. When it is pressed against the abutment portion 32, the inner door assembly 4 and the oven 1 form a sealed connection. Preferably, to enhance the sealing effect, a circumferential sealing ring is preferably provided on the contact ring surface between the inner door body 41 and the abutment portion 32 to further ensure the sealing performance of the connection.

[0026] In this embodiment, the inner door body 41 is connected to the inner door slide connecting plate 42. The two are configured to move horizontally along the upper and lower ends of the U-shaped opening 31 of the mounting plate 3 to approach or move away from the abutment 32. At the same time, the inner door body 41 can move linearly in the front and back direction independently of the inner door slide connecting plate 42 to press or disengage from the abutment 32.

[0027] Specifically, the inner door assembly 4 also includes a horizontal drive unit for driving the inner door body 41 and the inner door carriage connecting plate 42 to move horizontally. The horizontal drive unit includes a linear module 43 fixedly connected to the upper end of the mounting plate 3. The upper end of the inner door carriage connecting plate 42 is fixedly connected to the output end of the linear module 43. The horizontal drive unit also includes a guide rail 44 fixedly connected to the lower end of the mounting plate 3. The lower end of the inner door carriage connecting plate 42 is slidably connected to the guide rail 44 by a slider, thereby ensuring the stability and accuracy of the horizontal movement of the entire inner door assembly 4.

[0028] Furthermore, in this embodiment, to achieve the forward and backward movement of the inner door body 41, a front-to-back gap is provided between the inner door slide connecting plate 42 and the inner door body 41. The center of the inner door slide connecting plate 42 is provided with a rectangular mounting opening 421, and the upper and lower ends of the mounting opening 421 are respectively connected to front and rear driving parts for driving the inner door body 41 to move forward and backward. The upper and lower sets of front and rear driving parts have the same structure and are symmetrically distributed with respect to the horizontal axis of the mounting opening 421.

[0029] The structure of the lower front and rear drive unit is described in detail below, taking it as an example: The front and rear drive unit includes an L-shaped mounting base 45 fixedly connected to the mounting opening 421. The vertical plate of the L-shaped mounting base 45 is fixedly connected to the side of the inner door slide connecting plate 42 facing the inner door body 41 and extends into the gap between the two. The horizontal plate of the L-shaped mounting base 45 is connected to a rotatable guide wheel 46. Correspondingly, the inner door body 41 is fixedly connected to a cam track seat 47. The cam track seat 47 is provided with a cam track groove 48 adapted to the guide wheel 46. The cam track groove 48 is arranged obliquely to convert horizontal movement into linear movement in the front and rear direction.

[0030] Furthermore, the front and rear drive units also include an elastic element 49, which is horizontally arranged. Its two ends are fixedly connected to the side end of the cam track seat 47 and the inner door carriage connecting plate 42, respectively, and it is located on the side of the cam track seat 47 near the abutment part 32. A limiting element 50 is also connected to the mounting plate 3 to precisely limit the horizontal movement endpoint of the inner door body 41, ensuring that it accurately aligns with the abutment part 32 when closed. The elastic element 49 employs an elastic structure found in the prior art, such as a spring or tension spring.

[0031] When the inner door assembly 4 closes, it includes two consecutive movement processes. In the first movement process, the inner door slide connecting plate 42 and the inner door body 41 move horizontally towards the abutment 32 simultaneously. In the second movement process, the inner door body 41 presses against the abutment 32. Specifically, the horizontal drive unit drives the inner door slide connecting plate 42 to move horizontally towards the abutment 32. During this process, the tension of the elastic member 49 causes the cam track seat 47 and the inner door body 41 to move synchronously with the inner door slide connecting plate 42 until the inner door body 41 touches the limiting member 50. At this time, the inner door body 41 corresponds to the position of the abutment 32 in the horizontal direction. Then the inner door carriage connecting plate 42 continues to move laterally. Since the horizontal movement of the inner door body 41 has been blocked by the limiting member 50, relative movement occurs between the guide wheel 46 and the cam track groove 48. The guide wheel 46 rolls along the inclined cam track groove 48, thereby converting the horizontal displacement into a forward thrust, pushing the inner door body 41 against the abutment part 32 to achieve a tight seal. During the pressing process, the elastic member 49 is stretched. This force is small and does not affect the pressing process.

[0032] When the inner door assembly 4 is opened, the horizontal drive unit drives the inner door carriage connecting plate 42 to move away from the abutment part 32. First, the guide wheel 46 moves in the opposite direction within the cam track groove 48, causing the inner door body 41 to disengage from the pressure state of the abutment part 32. Subsequently, the force exerted by the elastic element 49 on the cam track seat 47 and the pushing force of the guide wheel 46 within the cam track groove 48 jointly drive the inner door body 41 to move synchronously away from the abutment part 32, thus opening the door.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
