Description

Technical Field

[0001] This invention relates to the field of in vitro diagnostic testing technology, and in particular to an automatic door and testing equipment. Background Technology

[0002] Large-scale testing equipment often involves a wide range of processes, from reagent preparation to testing, retesting, and result analysis. The equipment is large and has many steps, often requiring operation in multiple testing chambers. Furthermore, materials such as consumables and reagents need to be transferred between adjacent chambers. Therefore, openings are often left on the testing chambers.

[0003] In existing technologies, some testing chambers have their openings always open, but this can allow dust and other impurities to enter the equipment.

[0004] Some testing chambers have doors at their openings, which open vertically or rotate. Vertically opening doors often protrude from the chamber, resulting in poor overall integrity. Alternatively, vertically opening doors often require first sliding the door away from the chamber before pushing it up or down to open the opening. This necessitates two drive mechanisms, leading to complex structures, high costs, and large space requirements. Existing rotating doors often have limited opening angles, causing interference between the door and the output material. Furthermore, when closed, the door's fit with the chamber is poor, making it difficult to close tightly or causing the door to protrude from the chamber, further compromising the overall integrity of the testing chamber. Summary of the Invention

[0005] One object of the present invention is to provide an automatic door to at least solve one of the above-mentioned technical problems.

[0006] To achieve the above objectives, the first aspect of the present invention provides an automatic door connected to a housing and used to open and close openings on the housing wall of the housing. The automatic door includes a door frame, a door body, a door connector, a fixing and adjusting assembly, and a door drive mechanism.

One end of the first connecting part is connected to the inside of the door body through the fixing and adjusting assembly. The fixing and adjusting assembly can finely adjust its relative position with the door body and is detachably connected to the inside of the door body.

[0009] The door drive mechanism is connected to one end of the third connecting part to drive the door connector to rotate at least 90°, so that the door body is in a closed position that fits the inner edge and an open position that opens the opening. When the door body is in the closed position, the door body is located inside the opening.

[0010] The lower edge of the door frame is provided with a clearance groove. When the door is in the open position, the third connecting part is at least partially located in the clearance groove. The first connecting part, the second connecting part and the third connecting part form a clearance space for avoiding the lower edge.

[0011] Optionally, the fixing adjustment component includes:

[0013] A fixing screw is fixedly connected to the inner side of the door body, and the fixing screw passes through the U-shaped fixing groove and can move relative to the U-shaped fixing groove;

[0014] A fixing nut is provided, which can be threadedly connected to the fixing screw, and the fixing strip is clamped between the door body and the fixing nut.

[0015] Adjusting shims, wherein there are multiple adjusting shims, which can be selectively disposed between the fixing nut and the fixing bar, and the adjusting shims are sleeved on the fixing screw.

[0016] Optionally, when the door is in the closed position, the door is vertically positioned; and / or

[0017] When the door is in the open position, the door is horizontally positioned.

[0018] Optionally, the side of the door frame closest to the door body is the abutment surface, and an abutment groove is formed on the outer edge of the abutment surface;

[0019] The box wall includes a metal frame and a transparent panel. The metal frame has a viewing window, and the transparent panel is connected to the inside of the metal frame and covers the viewing window.

[0020] The door body and the metal frame abut against the abutment surface, the transparent plate is disposed in the abutment groove and abuts against the bottom of the abutment groove; and / or

[0021] The inner edge is connected to an elastic sealing part, and the door body can fit snugly against the elastic sealing part.

[0022] Optionally, the door drive mechanism includes a door drive component and a door pivot, the door drive component is used to drive the door pivot to rotate, and one end of the third connecting part is connected to the door pivot.

[0023] Optionally, the door drive mechanism further includes a first door drive fixing part and / or a second door drive fixing part;

[0024] The first fixing part of the door drive is connected to the door drive component and can be connected to the housing via a connector;

[0025] The second fixing part of the door drive is rotatably connected to the door pivot and can be connected to the housing through a connector.

[0026] Optionally, the door drive mechanism further includes a door drive transmission assembly, the door drive transmission assembly comprising:

[0027] A door drive drive pulley is connected to the output end of the door drive component;

[0028] A door drive driven pulley is connected to one end of the door shaft;

[0029] A door drive belt is fitted over the door drive drive pulley and the door drive driven pulley.

[0030] Optionally, the automatic door further includes a door position detection component, which is used to detect whether the door is in the closed position or the open position.

[0031] Optionally, the door arrival detection component includes:

[0032] A door positioning photoelectric sensor is connected to the housing;

[0033] A door stop plate is connected to the door hinge. When the door is in the closed position or in the open position, the door stop plate is located between the receiving end and the transmitting end of the door position photoelectric sensor.

[0034] Another object of the present invention is to provide a detection device to at least solve one of the above-mentioned technical problems.

[0035] To achieve this objective, the second aspect of the present invention adopts the following technical solution:

[0036] A testing device includes a housing and an automatic door. The housing has an opening on its wall, and the automatic door is rotatably connected to the housing and is used to open or close the opening.

[0037] As can be seen from the above, the technical solution provided by the present invention, since one end of the first connecting part is connected to the inner side of the door body through the fixed adjustment component, the fixed adjustment component can finely adjust its relative position with the door body. Therefore, when the door body is in the closed position, or when the door body cannot fit the inner edge of the door frame due to processing errors or installation errors, the position of the door body can be finely adjusted by adjusting the connection position between the door body and the fixed adjustment component, so that the door body fits the inner edge of the door frame completely, thus avoiding the situation where the door body is not closed tightly.

[0038] Because the door frame is connected to the inside of the enclosure, and has a ring-shaped structure with its inner edge aligned with the opening, when the door closes, it fits snugly against the inner edge of the door frame. The door and frame work together to completely close the opening, with the door positioned inside the opening. In other words, the door is embedded into the enclosure wall and does not protrude from it, resulting in a more robust overall enclosure design.

[0039] The door drive mechanism is connected to one end of the third connecting part. The door body and door connector rotate around one end of the third connecting part to close and open the opening. Therefore, the automatic door is connected to the housing by rotation, and only one door drive mechanism is needed to drive the door body to close and open the opening, thereby simplifying the structure of the detection equipment, reducing the space occupied by the automatic door, and lowering the cost of the automatic door.

[0040] The first, second, and third connecting parts form a clearance space to avoid the lower frame, ensuring that the door connectors do not interfere with the box wall or door frame during the rotation of the door between the open and closed positions. This allows the door and door connectors to rotate at least 90°, thus preventing interference with the conveyed materials when the door is in the open position. Furthermore, because the door and door connectors rotate around one end of the third connecting part, there is a distance between the door and that end. Therefore, as the door switches from the closed to the open position, it gradually moves away from the box wall, preventing interference and allowing the door to close smoothly.

[0041] The lower edge of the door frame has a clearance groove. When the door is in the open position, the third connecting part is at least partially located in the clearance groove. Therefore, when installing the automatic door, the entire automatic door can be closer to the box wall, saving space inside the detection box and making the automatic door occupy less space and the detection box structure more compact. At the same time, it can also ensure that the strength of the door connectors is not affected.

[0042] Automatic doors prevent dust and other contaminants from entering the cabinet through the opening. The structure of automatic doors reduces the space they occupy, lowers costs, ensures that the door opening is not less than 90°, and that the opening does not protrude from the cabinet when the door is closed, resulting in a better overall appearance of the cabinet.

[0064] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present invention are shown in the accompanying drawings, not all of them.

[0065] This invention defines certain directional terms. Unless otherwise stated, the directional terms used, such as "up," "down," "left," "right," "inner," and "outer," are used for ease of understanding and therefore do not constitute a limitation on the scope of protection of this invention.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0067] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0068] like Figure 1 and Figure 2 As shown, this embodiment provides a testing device, which includes a housing 100 and an automatic door. The housing wall 101 of the housing 100 is provided with an opening 1014. The automatic door is rotatably connected to the housing 100 and is used to open or close the opening 1014, thereby preventing dust and other particles from entering the housing 100 through the opening 1014. The automatic door is connected to the housing 100 by rotation, so only one set of door drive mechanism 35 is needed to drive the door 32 to close and open the opening 1014, thereby simplifying the structure of the testing device, reducing the space occupied by the automatic door, and reducing the cost of the automatic door.

[0069] like Figure 1 As shown, optionally, the box wall 101 includes a metal frame 1011 and a transparent panel 1012, and the metal frame 1011 has a viewing window 1013 (e.g., Figure 4 As shown, the transparent plate 1012 is connected to the inside of the metal frame 1011 and covers the viewing window 1013, so that the situation inside the box 100 can be observed through the transparent plate 1012.

[0070] like Figures 1-4 As shown, the automatic door is located roughly at the lower part of the housing 100. Of course, in other alternative embodiments, the opening 1014 and the position of the automatic closing door can be set as needed.

[0071] like Figures 3-7 As shown, the automatic door provided in this embodiment includes a door frame 31, a door body 32, a door connector 33, a fixing and adjusting assembly 34, and a door drive mechanism 35.

[0072] like Figure 3 and Figure 4 As shown, the door frame 31 is connected to the inner side of the housing 100. The door frame 31 has a ring-shaped structure, and its inner edge 312 is directly opposite the opening 1014. In this embodiment, the opening 1014 is rectangular, and the door frame 31 and the door body 32 are also rectangular, that is, the ring structure is a rectangular ring. Of course, in other embodiments, the opening 1014 can also be other shapes.

[0073] like Figure 3 and Figure 6As shown, the door connector 33 includes a first connecting part 331, a second connecting part 332, and a third connecting part 333 connected in a U-shape in sequence. The door connector 33 has a simple structure, is easy to process, and allows for control of processing accuracy. One end of the first connecting part 331 is connected to the inside of the door body 32 through a fixing and adjusting assembly 34. The fixing and adjusting assembly 34 can finely adjust its relative position to the door body 32 and is detachably connected to the inside of the door body 32.

[0074] like Figure 5 and Figure 7 As shown, the door drive mechanism 35 is connected to one end of the third connecting part 333 to drive the door connector 33 to rotate at least 90°, so that the door body 32 is in the closed position of fitting the inner edge 312 and the open position of opening the opening 1014. When the door body 32 is in the closed position, the door body 32 is located inside the opening 1014.

[0075] like Figure 10 As shown, the lower edge 311 of the door frame 31 has an clearance groove 3111, and the door body 32 is located as shown. Figure 5 When in the open position shown, the third connecting part 333 is at least partially located in the clearance groove 3111; the first connecting part 331, the second connecting part 332 and the third connecting part 333 form a clearance space 334 for clearance of the lower frame 311.

[0076] In this embodiment, the upper end of the door 32 rotates downward to open the opening 1014. The door frame 31 may also include an upper frame 315, a first side frame 316, and a second side frame 317. The upper frame 315 is located above the lower frame 311. The upper frame 315, the first side frame 316, the lower frame 311, and the second side frame 317 are connected in sequence to form a ring structure. Specifically, the ring structure is a rectangular ring to cooperate with the rectangular opening 1014.

[0077] In other alternative embodiments, the lower end of the door 32 is rotated from bottom to top to open the opening 1014. At this time, the upper frame 315 is located below the lower frame 311. Therefore, "upper" and "lower" here are not limitations on specific positions.

[0078] Since one end of the first connecting part 331 is connected to the inner side of the door body 32 through the fixed adjustment component 34, the fixed adjustment component 34 can finely adjust its relative position with the door body 32. Therefore, when the door body 32 is in the closed position, or when the door body 32 cannot fit the inner edge 312 of the door frame 31 due to processing errors or installation errors, the position of the door body 32 can be finely adjusted by adjusting the connection position between the door body 32 and the fixed adjustment component 34, so that the door body 32 fits the inner edge 312 of the door frame 31 completely, thus avoiding the situation where the door body 32 is not closed tightly.

[0079] Since the door frame 31 is connected to the inside of the box 100, the door frame 31 has a ring-shaped structure, and the inner edge 312 of the door frame 31 is directly opposite the opening 1014. When the door 32 closes the opening 1014, the door 32 fits against the inner edge 312 of the door frame 31. The door frame 31 and the door 32 cooperate to completely close the opening 1014. The door 32 is located inside the opening 1014, that is, the door 32 is embedded in the box wall 101. The door 32 does not protrude from the box wall 101, making the box 100 more integral.

[0080] The door drive mechanism 35 is connected to one end of the third connecting part 333. The door body 32 and the door connector 33 rotate around one end of the third connecting part 333 to close and open the opening 1014. Therefore, the automatic door is connected to the housing 100 by rotation. Only one set of door drive mechanism 35 is needed to drive the door body 32 to close and open the opening 1014, thereby simplifying the structure of the detection equipment, reducing the space occupied by the automatic door, and reducing the cost of the automatic door.

[0081] The first connecting part 331, the second connecting part 332, and the third connecting part 333 form a clearance space 334 to avoid the lower frame 311. This ensures that the door connector 33 does not interfere with the box wall 101 or the door frame 31 during the rotation of the door body 32 between the open and closed positions. Consequently, the door body 32 and the door connector 33 can rotate at least 90°. Therefore, when the door body 32 is in the open position, it will not interfere with the conveyed materials. In addition, since the door body 32 and the door connector 33 rotate around one end of the third connecting part 333, there is a distance between the door body 32 and one end of the third connecting part 333. Therefore, during the process of switching the door body 32 from the closed position to the open position, the door body 32 will gradually move away from the box wall 101. Thus, the door body 32 will not interfere with the box wall 101, and the door body 32 can be closed smoothly.

[0082] The lower frame 311 of the door frame 31 has a clearance groove 3111. When the door body 32 is in the open position, the third connecting part 333 is at least partially located in the clearance groove 3111. Therefore, when installing the automatic door, the entire automatic door can be closer to the box wall 101, saving space inside the detection box and making the automatic door occupy less space and the structure of the detection box more compact. At the same time, it can also ensure that the strength of the door connector 33 is not affected.

[0083] Automatic doors can prevent dust and other contaminants from entering the housing 100 through the opening 1014. The structure of the automatic door reduces the space occupied by the automatic door, lowers costs, ensures that the opening angle of the door 32 is not less than 90°, and ensures that the door 32 does not protrude from the opening 1014 when closed, making the overall appearance of the housing 100 better.

[0084] In one specific embodiment, when the door 32 switches from the open position to the closed position, the door drive mechanism 35 drives the door connector 33 to rotate 90°, and the door 32 also rotates 90° accordingly. For example, as shown... Figure 1 and Figure 8 As shown, when the door 32 is in the closed position, the door 32 is vertically positioned, and both the door 32 and the box wall 101 are vertically positioned, closing the opening 1014. Figure 2 and Figure 9 As shown, when the door 32 is in the open position, the door 32 is set horizontally. On the one hand, this prevents the door 32 from interfering with the output materials; on the other hand, relative to the obtuse angle between the door 32 and the vertical direction, when the door 32 is stationary in a horizontal setting, the door connector 33, especially the third connecting part 333, is subjected to relatively small forces at the connection between it and the door drive mechanism 35, thereby avoiding deformation of the door connector 33 and thus ensuring the door 32.

[0085] like Figure 3 and Figure 6 As shown, the fixing adjustment assembly 34 includes a fixing strip 341, a fixing screw 342, a fixing nut 343, and an adjusting shim. At least one end of the fixing strip 341 has a U-shaped fixing groove 3411. The fixing strip 341 is connected to one end of the first connecting part 331. Optionally, the fixing strip 341 and the door connector 33 are integrally formed. The fixing screw 342 is fixedly connected to the inner side of the door body 32. The fixing screw 342 passes through the U-shaped fixing groove 3411 and can move relative to the U-shaped fixing groove 3411. That is, the size of the U-shaped fixing groove 3411 is larger than the size of the fixing screw 342. Therefore, when the fixing screw 342 is inserted into the U-shaped fixing groove 3411, the relative position between the door body 32 and the fixing strip 341 can be finely adjusted. The fixing nut 343 can be threadedly connected to the fixing screw 342, causing the fixing strip 341 to be clamped between the door body 32 and the fixing nut 343, thereby fixing the door body 32 and the fixing strip 341. Adjusting shims are fitted onto the fixing screw 342. Multiple adjusting shims are available, and they can be selectively positioned between the fixing nut 343 and the fixing strip 341. Optionally, no adjusting shims may be placed between the fixing nut 343 and the fixing strip 341, or one or more adjusting shims may be placed. The adjusting shims can be metal shims or elastic shims such as rubber.

[0086] For example, when the door 32 needs to be adjusted up, down, left, or right relative to the opening 1014, the relative position of the fixing screw 342 and the U-shaped fixing groove 3411 can be adjusted accordingly. When the door 32 is closed and does not fit tightly against the door frame 31, the adjusting shim between the fixing nut 343 and the fixing strip 341 can be removed.

[0087] Optionally, both ends of the fixing strip 341 are provided with U-shaped fixing grooves 3411. There are two door connectors 33, and the direction in which the two door connectors 33 are sequentially arranged is perpendicular to the direction in which the two U-shaped fixing grooves 3411 on the same fixing strip 341 are sequentially arranged. That is, a total of four U-shaped fixing grooves 3411 and four fixing screws 342 are provided. The four U-shaped fixing grooves 3411 are located at the four corners of the rectangle, and the four fixing screws 342 are located at the four corners of the rectangle. Each fixing screw 342 can be inserted into one U-shaped fixing groove 3411. When the door body 32 is tilted relative to the door frame 31, the number of adjusting shims fitted on one or more fixing screws 342 can be adjusted as needed, thereby making the door body 32 completely fit with the inner edge 312 of the door frame 31. It is understood that only one fixing screw 342 is shown in the figure with a fixing nut 343 connected to it; in reality, each fixing screw 342 is connected to a fixing nut 343.

[0088] like Figure 11 As shown, the side of the door frame 31 closest to the door body 32 is the abutment surface 313, and an abutment groove 314 is formed on the outer edge of the abutment surface 313. It can be understood that the inner edge 312 is part of the abutment surface 313. The outer edge of the abutment surface 313 is relative to the inner edge 312 of the door frame 31. "Inner" and "outer" are relative to the inner and outer rings of the annular structure, respectively. The position closer to the inner ring of the annular structure is the inner edge 312, and the position closer to the outer ring of the annular structure is the outer edge.

[0089] In an optional embodiment, the inner edge 312 is connected to an elastic sealing part, and the door body 32 can fit snugly against the elastic sealing part. The elastic sealing part can be a silicone pad or foam, etc., and is connected to the inner edge 312 by means of adhesive or other methods to enhance the sealing and fit between the door frame 31 and the door body 32, thereby improving the sealing effect.

[0090] like Figure 12 and Figure 13 As shown, the transparent panel 1012 is connected to the inner side of the metal frame 1011. The door 32 and the metal frame 1011 abut against the abutment surface 313. The transparent panel 1012 is disposed in the abutment groove 314 and abuts against the bottom of the abutment groove 314, thereby avoiding gaps between the box wall 101 and the door frame 31, and also avoiding gaps between the door frame 31 and the door 32. In this embodiment, since the transparent panel 1012 is connected to the inner side of the metal frame 1011, the door 32 does not protrude from the metal frame 1011, but slightly protrudes from the transparent panel 1012. Overall, the door 32 does not protrude from the box wall 101.

[0091] like Figure 5 and Figure 7As shown, the door drive mechanism 35 includes a door drive component 351 and a door pivot 352. The door drive component 351 drives the door pivot 352 to rotate. One end of the third connecting part 333 is connected to the door pivot 352, meaning that the door body 32 and the door connector 33 achieve fixed-axis rotation through the door pivot 352. The door drive component 351 can be a stepper motor, etc.

[0092] The door drive mechanism 35 also includes a door drive transmission assembly, which includes a door drive drive pulley 355, a door drive driven pulley 356, and a door drive belt 357. The door drive drive pulley 355 is connected to the output end of the door drive component 351; the door drive driven pulley 356 is connected to one end of the door shaft 352; and the door drive belt 357 is sleeved around the door drive drive pulley 355 and the door drive driven pulley 356. The door drive transmission assembly allows the output end of the door drive component 351 to be non-axial with the door shaft 352, thus facilitating the installation of the door drive component 351.

[0093] To facilitate the fixing of the door drive component 351, the door drive mechanism 35 may optionally include a door drive first fixing part 353, which is connected to the door drive component 351 and can be connected to the housing 100 by bolts or other connecting parts.

[0094] To facilitate fixing the door hinge 352, the door drive mechanism 35 may optionally include a second door drive fixing part 354, which is rotatably connected to the door hinge 352 and can be connected to the housing 100 by bolts or other connecting parts. In this embodiment, four second door drive fixing parts 354 are provided at axial intervals along the door hinge 352 to improve the stability of the door hinge 352.

[0095] To facilitate determining the position of the door 32 and the number of steps or angles of rotation of the door drive 351, the automatic door also includes a door position detection component 36, which is used to detect whether the door 32 is in the closed position or the open position.

[0096] The door positioning detection component 36 includes a door positioning photoelectric sensor 361 and a door stop 362. The door positioning photoelectric sensor 361 is connected to the housing 100. The door stop 362 is connected to the door hinge 352. When the door 32 is in the closed or open position, the door stop 362 is located between the receiving end and the transmitting end of the door positioning photoelectric sensor 361. In this embodiment, as... Figure 5 As shown, when the door 32 is in the open position, the door stop 362 is located between the receiving end and the transmitting end of the door position photoelectric sensor 361. The door position detection component 36 can detect that the door 32 is open to the correct position, and the number of steps or angle of rotation of the door drive component 351 returns to zero. Figure 7As shown, when the door 32 leaves the open position (including when it is in the closed position), the door stop 362 is outside the receiving end and transmitting end of the door position photoelectric sensor 361. When the door drive 351 rotates by 90° or by 90°, the door drive 351 stops working and the door 32 rotates to the position (i.e., rotates to the closed position).
