Description

Technical Field

[0001] The utility model relates to the technical field of in vitro diagnosis and detection, in particular to an automatic door and detection equipment. Background Art

[0002] Large-scale testing equipment often starts with reagent configuration, testing, retesting and result analysis. The equipment is large in size and has many processes. It often needs to be carried out in multiple testing chambers, and materials such as consumables and reagents need to be transferred between adjacent chambers. Therefore, openings are often left on the testing chambers.

[0003] In the prior art, the openings of some detection boxes are always open, but impurities such as dust may enter the equipment.

[0004] Some detection boxes are provided with doors at the opening, which open up and down, or rotate to open. Among them, the doors that open up and down often protrude from the box, resulting in poor integrity of the detection box. Or in the case of doors that open up and down, it is often necessary to first translate the door to move the door away from the box, and then push the door up or down to open the opening, which requires two drive mechanisms to work together to open the door, resulting in a complex structure, high cost, and large space occupation. The doors that rotate to open in the prior art often have a limited opening angle, resulting in interference between the door and the output material, and after closing the door, the door and the box have a poor fit, resulting in the door being difficult to close tightly or protruding from the box, resulting in poor integrity of the box.

[0034] A door stopper is connected to the door shaft. When the door body is located at the closed position or the open position, the door stopper is located between the receiving end and the transmitting end of the door-in-place photoelectric sensor.

[0035] Another object of the present invention is to provide a detection device to at least solve one of the above technical problems.

[0036] To achieve this purpose, the second aspect of the utility model adopts the following technical solutions:

[0037] A detection device comprises a box body and an automatic door. An opening is arranged on a box wall of the box body. The automatic door is rotatably connected to the box body and is used to open or close the opening.

[0038] As can be seen from the above, the technical solution provided by the utility model is that one end of the door connecting piece is connected to the inner side of the door body through a fixed adjusting component, and the fixed adjusting component is capable of fine-tuning its relative position with the door body. Therefore, when the door body is in a closed position, or due to processing errors or installation errors, the door body cannot fit the inner edge of the door frame, the position of the door body can be fine-tuned by adjusting the connection position between the door body and the fixed adjusting component, so that the door body can completely fit the inner edge of the door frame, thereby avoiding the situation where the door body is not closed tightly.

[0039] Since the door frame is connected to the inner side of the box body, the door frame is annular in structure, and the inner edge of the door frame is opposite to the opening, when the door body closes the opening, the door body fits to the inner edge of the door frame, and the door frame and the door body cooperate to completely close the opening. The door body is located in the opening, that is, the door body is embedded in the box wall, and the door body does not protrude from the box wall, making the box body more integrated.

[0040] The door drive mechanism is connected to the other end of the door connector, and the door body rotates around the other end of the door connector to close and open the opening. Therefore, the automatic door is connected to the box body by rotation, and only one set of 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 reducing the cost of the automatic door.

[0041] The door connector has an escape space for avoiding the lower frame, so that the door connector will not interfere with the box wall and the door frame during the rotation of the door body between the open position and the closed position, so that the door body and the door connector can rotate 90 degrees, so when the door body is in the open position, it will not interfere with the conveyed materials. In addition, since the door body rotates around the other end of the door connector, the door body is a distance away from the other end of the door connector. Therefore, in the process of switching the door body from the closed position to the open position, the door body will gradually move away from the box wall. Therefore, the door body will not interfere with the box wall, so the door body can be closed smoothly.

[0042] Automatic doors can prevent dust and other substances from entering the box through the opening. The structure of the automatic door reduces the space occupied by the automatic door, reduces costs, ensures that the door opening is not less than 90°, and that the opening does not protrude from the box when the door is closed, giving the box a better overall feel.

[0043] The lower frame of the door frame is provided with an avoidance groove, and when the door body is in the open position, the third connection part is at least partially located in the avoidance groove. Therefore, when the automatic door is installed, the automatic door as a whole can be closer to the box wall, saving space inside the detection box, 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 connection piece is not affected. BRIEF DESCRIPTION OF THE DRAWINGS

[0069] like Figure 1 and Figure 2 As shown, this embodiment provides a detection device, which includes a box body 100 and an automatic door. An opening 1014 is provided on the box wall 101 of the box body 100. The automatic door is rotatably connected to the box body 100 and is used to open or close the opening 1014, thereby preventing dust and the like from entering the box body 100 from the opening 1014. The automatic door is connected to the box body 100 in a rotatable manner, so only one set of door driving mechanism 35 is needed to drive the door body 32 to close and open the opening 1014, thereby simplifying the structure of the detection device, reducing the space occupied by the automatic door and reducing the cost of the automatic door.

[0070] like Figure 1 As shown, optionally, the box wall 101 includes a metal frame 1011 and a transparent plate 1012, and the metal frame 1011 is provided with a perspective window 1013 (such as Figure 4 As shown), the transparent plate 1012 is connected to the inner side of the metal frame 1011 and covers the perspective window 1013, so that the situation inside the box 100 can be easily observed through the transparent plate 1012.

[0071] like Figure 1-Figure 4 As shown, the automatic door is approximately located at the lower part of the box body 100. Of course, in other optional embodiments, the position of the opening 1014 and the automatic door closing can be set as needed.

[0072] like Figure 3-Figure 7 As shown, the automatic door provided in this embodiment includes a door frame 31, a door body 32, a door connector 33, a fixed adjustment component 34 and a door driving mechanism 35.

[0073] like Figure 3 and Figure 4 As shown, the door frame 31 is connected to the inner side of the box body 100, and the door frame 31 is an annular structure, and the inner edge 312 of the door frame 31 is opposite to 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 annular structure is a rectangular ring. Of course, in other embodiments, the opening 1014 can also be other shapes.

[0074] like Figure 3 and Figure 6As shown, one end of the door connector 33 is connected to the inner side of the door body 32 through a fixed adjustment component 34. The fixed adjustment component 34 can fine-tune its relative position with the door body 32 and is detachably connected to the inner side of the door body 32. Figure 5 and Figure 7 As shown, the door driving mechanism 35 is connected to the other end of the door connecting member 33 to drive the door connecting member 33 to rotate 90 degrees, so that the door body 32 is located at a closed position that fits the inner edge 312 and an open position that opens the opening 1014. When the door body 32 is located at the closed position, the door body 32 is located in the opening 1014. The door connecting member 33 forms an escape space 334 for escaping the lower frame 311.

[0075] like Figure 5 and Figure 7 As shown, the door driving mechanism 35 is connected to the other end of the door connecting member 33 to drive the door connecting member 33 to rotate 90° so that the door body 32 is located in a closed position that fits the inner edge 312 and an open position that opens the opening 1014. When the door body 32 is in the closed position, the door body 32 is located in the opening 1014.

[0076] In this embodiment, the upper end of the door body 32 rotates from top to bottom to open the opening 1014, and 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 on the upper side of the lower frame 311, and 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 an annular structure. Specifically, the annular structure is a rectangular ring to cooperate with the rectangular opening 1014.

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

[0078] Since one end of the door connecting piece 33 is connected to the inner side of the door body 32 through the fixed adjusting component 34, the fixed adjusting component 34 can fine-tune its relative position with the door body 32. Therefore, when the door body 32 is in a closed position, or due to processing errors or installation errors, the door body 32 cannot fit the inner edge 312 of the door frame 31, the position of the door body 32 can be fine-tuned by adjusting the connection position between the door body 32 and the fixed adjusting component 34, so that the door body 32 can completely fit the inner edge 312 of the door frame 31, thereby avoiding the situation where the door body 32 is not closed tightly.

[0079] Since the door frame 31 is connected to the inner side of the box body 100, the door frame 31 is annular in structure, and the inner edge 312 of the door frame 31 is opposite to the opening 1014, when the door body 32 closes the opening 1014, the door body 32 fits to the inner edge 312 of the door frame 31, and the door frame 31 and the door body 32 cooperate to completely close the opening 1014, and the door body 32 is located in the opening 1014, that is, the door body 32 is embedded in the box wall 101, and the door body 32 does not protrude from the box wall 101, so that the integrity of the box body 100 is stronger.

[0080] The door driving mechanism 35 is connected to the other end of the door connecting member 33, and the door body 32 and the door connecting member 33 rotate around the other end of the door connecting member 33 to close and open the opening 1014. Therefore, the automatic door is connected to the box body 100 by rotation, and only one set of door driving 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 door connector 33 has an escape space 334 for avoiding the lower frame 311, so that the door connector 33 will not interfere with the box wall 101 and the door frame 31 during the rotation of the door body 32 between the open position and the closed position, so that the door body 32 and the door connector 33 can rotate 90°, so 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 the other end of the door connector 33, the door body 32 is at a distance from the other end of the door connector 33, so in the process of the door body 32 switching from the closed position to the open position, the door body 32 will gradually move away from the box wall 101, so the door body 32 will not interfere with the box wall 101, so the door body 32 can be closed smoothly.

[0082] The automatic door can prevent dust and the like from entering the box body 100 from the opening 1014. The structure of the automatic door reduces the space occupied by the automatic door, reduces costs, ensures that the opening of the door body 32 is not less than 90°, and that the door body 32 closes the opening 1014 and does not protrude from the box body 100, thereby giving the box body 100 a better overall feel.

[0083] Exemplarily, the door connector 33 includes a first connector 331, a second connector 332 and a third connector 333 which are connected in sequence in a U shape. The first connector 331, the second connector 332 and the third connector 333 form an avoidance space 334. The door connector 33 has a simple structure and is easy to process and control processing accuracy.

[0084] One end of the first connection part 331 is connected to the fixed adjustment assembly 34, and the door driving mechanism 35 is connected to one end of the third connection part 333. The first connection part 331, the second connection part 332 and the third connection part 333 form an escape space 334 for escaping the lower frame 311, so that when the door body 32 rotates between the open position and the closed position, the door connection member 33 will not interfere with the box wall 101 and the door frame 31, thereby allowing the door body 32 and the door connection member 33 to rotate 90°.

[0085] Alternatively, if Fig.10 As shown, the lower frame 311 of the door frame 31 is provided with an avoidance groove 3111. When the door body 32 is in the open position, the third connection portion 333 is at least partially located in the avoidance groove 3111. Therefore, when the automatic door is installed, the automatic door as a whole can be closer to the box wall 101, saving space inside the detection box, 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.

[0086] When the door body 32 switches from the open position to the closed position, the door driving mechanism 35 drives the door connecting member 33 to rotate 90°, and the door body 32 also rotates 90° accordingly. Figure 1 and Figure 8 As shown, when the door body 32 is in the closed position, the door body 32 is vertically arranged, and the door body 32 and the box wall 101 are both vertically arranged, closing the opening 1014. Figure 2 and Fig. 9 As shown, when the door body 32 is in the open position, the door body 32 is horizontally arranged. On the one hand, the door body 32 will not interfere with the output material. On the other hand, relative to the obtuse angle between the door body 32 and the vertical direction, when the door body 32 is stationary in the horizontal arrangement, the force on the door connecting member 33, especially the connection between the third connecting part 333 and the door driving mechanism 35 is relatively small, thereby avoiding deformation of the door connecting member 33 and further ensuring the door body 32.

[0087] like Figure 3 and Figure 6As shown, the fixing and adjusting assembly 34 includes a fixing bar 341, a fixing screw 342, a fixing nut 343 and an adjusting gasket. At least one end of the fixing bar 341 is provided with a U-shaped fixing groove 3411. The fixing bar 341 is connected to one end of the first connecting portion 331. Optionally, the fixing bar 341 and the door connecting member 33 are an integral structure. The fixing screw 342 is fixedly connected to the inner side of the door body 32. The fixing screw 342 is inserted into 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, and thus 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 bar 341 can be finely adjusted. The fixing nut 343 can be threadedly connected to the fixing screw 342, and the fixing bar 341 is sandwiched between the door body 32 and the fixing nut 343, so that the door body 32 and the fixing bar 341 are fixed. The adjusting gasket is sleeved on the fixing screw 342, and the number of the adjusting gaskets is multiple, and can be selectively arranged between the fixing nut 343 and the fixing bar 341. Optionally, no adjusting gasket may be placed between the fixing nut 343 and the fixing bar 341, or one or more adjusting gaskets may be placed. The adjusting gasket may be a metal gasket or an elastic gasket such as rubber.

[0088] For example, when the door body 32 needs to be adjusted up, down, left, or right relative to the opening 1014, the relative positions of the fixing screw 342 and the U-shaped fixing groove 3411 can be adjusted accordingly. When the door body 32 is closed and the door body 32 is not close to the door frame 31, the adjustment gasket between the fixing nut 343 and the fixing strip 341 can be removed.

[0089] Optionally, both ends of the fixing strip 341 are provided with U-shaped fixing grooves 3411, the number of the door connectors 33 is two, 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, the four fixing screws 342 are located at the four corners of the rectangle, and each fixing screw 342 can be inserted into a U-shaped fixing groove 3411. When the door body 32 is tilted relative to the door frame 31, the number of adjustment gaskets sleeved on one or more fixing screws 342 can be adjusted as needed, so that the door body 32 is completely fitted with the inner edge 312 of the door frame 31. It can be understood that, only one fixing screw 342 is shown in the figure as being connected to a fixing nut 343, and in fact, each fixing screw 342 is connected to a fixing nut 343.

[0090] like Fig.11As shown, the side of the door frame 31 close to the door body 32 is an abutting surface 313, and an abutting groove 314 is provided on the outer edge of the abutting surface 313. It can be understood that the inner edge 312 is a part of the abutting surface 313. The outer edge of the abutting surface 313 is relative to the inner edge 312 of the door frame 31, and the inner and outer are relative to the inner and outer rings of the annular structure. The position close to the inner ring of the annular structure is the inner edge 312, and the position close to the outer ring of the annular structure is the outer edge.

[0091] In an optional embodiment, the inner edge 312 is connected to an elastic sealing portion, and the door body 32 can be closely attached to the elastic sealing portion. The elastic sealing portion can be a silicone pad or foam, etc., which is connected to the inner edge 312 by bonding or other means to enhance the sealing and fit between the door frame 31 and the door body 32, thereby improving the sealing effect.

In this embodiment, four door drive second fixing portions 354 are arranged at intervals along the axial direction of the door shaft 352 to improve the stability of the door shaft 352.

[0097] To facilitate determination of the position of the door body 32 and the number of steps or angles of rotation of the door drive 351 , the automatic door further comprises a door in-position detector 36 , which is used to detect whether the door body 32 is in a closed position or in an open position.

[0098] The door in position detection member 36 includes a door in position photoelectric sensor 361 and a door stopper 362. The door in position photoelectric sensor 361 is connected to the box body 100. The door stopper 362 is connected to the door shaft 352. When the door body 32 is in the closed position or in the open position, the door stopper 362 is located between the receiving end and the transmitting end of the door in position photoelectric sensor 361. Figure 5 As shown, when the door body 32 is in the open position, the door stopper 362 is located between the receiving end and the transmitting end of the door in-position photoelectric sensor 361, and the door in-position detection member 36 can detect that the door body 32 is in position, and the number of steps or angle of rotation of the door driving member 351 is reset to zero. Figure 7 As shown, when the door body 32 leaves the open position (including being in the closed position), the door stopper 362 is located outside the receiving end and the transmitting end of the door in place photoelectric sensor 361, and when the number of steps or angles rotated by the door driver 351 is 90°, the door driver 351 stops working and the door body 32 rotates into place (i.e., rotates to the closed position).
