The utility model discloses a darkroom subassembly is used for providing the dark surrounds for the detection of sample, and the darkroom subassembly cooperates automatic loading and the uninstallation in order to realize the sample with sampling device usually.
Referring to fig. 1 and 2, the darkroom assembly of the first embodiment of the present invention comprises a darkroom main body 100 and a detecting device 200, wherein the darkroom main body 100 is used for cooperating with a darkroom door to form the dark environment, and the detecting device 200 is used for detecting a sample in the darkroom main body 100.
The darkroom main body 100 is used for placing a sample to be detected, and as shown in the figure, the darkroom main body 100 comprises a substantially rectangular box structure, referring to fig. 3, a cavity 110 is arranged in the darkroom main body 100, the cavity 110 forms a first opening 120 on the darkroom main body 100, and the first opening 120 is used for allowing the sample to enter and exit the cavity 110. In general, a sample is stored or attached in a carrier such as a sample container, for example, in the sample card 400 shown in fig. 2, so that the first opening 120 is a rectangular opening of a corresponding shape, and the dimension in the longitudinal direction (left-right direction in fig. 2) is larger than the dimension in the width direction (left-right direction in fig. 2) of the sample card 400, and the dimension in the width direction (front-back direction in fig. 2) of the first opening 120 is larger than the dimension in the thickness direction (front-back direction in fig. 2) of the sample card 400, so that the sample card 400 can pass through the first opening 120 without being obstructed. In addition, the first opening 120 may be disposed at the top of the darkroom main body 100, so that the sample card 400 may slide in the vertical direction within the darkroom main body 100 under the action of gravity, ensuring that the sample card 400 may reach a preset detection position.
The cavity wall of the cavity 110 has at least one first guide surface 130, and the distance between the first guide surface 130 and the wall surface of the cavity 110 is gradually reduced along the insertion direction (e.g., from the top to the bottom in the drawing) of the sample card 400, so that the first guide surface can contact with the corresponding side of the sample card 400 to guide the insertion of the sample card 400. In general, since the direction in which the sample card 400 is displaced is not constant, it is necessary to guide the sample card 400 on each side in order to be able to adapt to an actual usage situation, and there are various cases for the allocation of the guide surfaces based on this concept, including: the darkroom main body 100 is provided with a whole guide surface, a part of the guide surface is arranged on the darkroom main body 100, and the other part of the guide surface is arranged on the guided sample card 400. As one implementation manner, referring to fig. 2, the sample card 400 is provided with third guide surfaces 410 on both sides (e.g., left and right sides in the drawing) in the width direction, and the third guide surfaces 410 are specifically provided at the connection between the bottom surface and the side surface of the sample card 400, and may be circular arc surfaces as shown in the drawing. It can be understood that, since the sample card 400 has a large size in the width direction, it is convenient to process a guide surface having a large area, and the guide ability is enhanced. The darkroom main body 100 adapted to the sample card 400 is provided with two first guide surfaces 130, as shown in fig. 3, along the circumferential direction of the first opening 120, the two first guide surfaces 130 are oppositely arranged, i.e. located on the front and rear side cavity walls. Along the inserting direction, the distance between the two first guide surfaces 130 is gradually reduced, so that when the sample card 400 deviates in the left-right direction, the sample card can be guided by the contact of the third guide surface 410 and the darkroom main body 100, and when the sample card 400 deviates in the front-back direction, the sample card can be guided by the contact of the first guide surfaces 130 and the two sides of the thickness direction (front-back direction) of the sample card 400, that is, the guide surfaces of the sample card 400 can be utilized to realize the guide in partial directions, thereby being beneficial to simplifying the structure of the darkroom main body 100.
It can be understood that in other embodiments, at least one first guiding surface 130 may be disposed on the cavity wall of the cavity 110, for example, the cavity wall on the front side of the cavity 110 is provided with the first guiding surface 130, and the cavity wall on the rear side, the left side and the right side of the sample card 400 are provided with the third guiding surfaces 410, which can also achieve the effect of achieving the guiding in all directions.
As another implementation manner of the guide surface allocation scheme, the cavity 110 may be a rectangular cavity convenient for processing, referring to fig. 3, a cavity wall of the cavity 110 has four first guide surfaces 130, the four first guide surfaces 130 are sequentially arranged along a circumferential direction of the first opening, specifically, the front side, the rear side, the left side and the right side of the cavity 110 are all provided with the first guide surfaces 130 (only the front side, the rear side and the right side of the first guide surfaces 130 are shown in the figure due to a cutting relationship), the front side and the rear side of the first guide surfaces 130 are arranged opposite, and the left side and the right side of the first guide surfaces 130 are arranged opposite. The distances between the front and rear first guide surfaces 130 and between the left and right first guide surfaces 130 in the insertion direction of the sample card 400 (e.g., from above to below in the drawing) are reduced, so that even if the sample card 400 is displaced during the insertion process or has been displaced before the insertion, the first guide surfaces 130 can guide and correct the errors, thereby reducing the accuracy requirement of the sampling apparatus.
It can be understood that the inclination angle of each first guide surface 130 may be the same or different. In addition, the first guide surface 130 may be a plane surface in the drawing, or may be a convex or concave arc surface.
The detecting unit 200 may have a known structure such as a photomultiplier, and the detecting unit 200 may be connected to the darkroom main body 100 and detect the sample in the darkroom main body 100. In addition, when the darkroom assembly is applied to the detection device, the detection device 200 is electrically connected with the control device of the detection device, and the detected signal can be sent to the control device.
Referring to fig. 3, the first guide surface 130 is located at the middle section of the cavity wall of the cavity 110, that is, the sample card 400 needs to contact with the first guide surface 130 after entering the cavity 110 for a certain distance, at this time, the sectional area of the cavity 110 changes, taking the first guide surface 130 as a boundary, the portion relatively close to the first opening 120 is the first cavity 111, the portion relatively far away from the first opening 120 is the second cavity 112, and the sectional area of the first cavity 111 is larger than the sectional area of the second cavity 112. Based on the above structure, the cavity wall of the cavity 110 is further provided with four first limiting surfaces 140, specifically, the first limiting surfaces 140 are disposed on the cavity wall of the second cavity 112, so that the first guide surfaces 130 and the corresponding first limiting surfaces 140 are sequentially disposed along the insertion direction of the sample card 400. The four first limiting surfaces 140 correspond to the four first guiding surfaces 130 one by one, that is, the first limiting surfaces 140 are disposed on the front side, the rear side, the left side and the right side of the cavity 110 (due to the cut-away relationship, and the sample card 400 is blocked, the first limiting surfaces 140 on the front side and the rear side are visible in the figure), the distance between the front side and the rear side of the first limiting surface 140 is equal to or slightly greater than the thickness of the sample card 400 in the direction, and the distance between the left side and the right side of the first limiting surface 140 is equal to or slightly greater than the width of the sample card 400 in the direction, so that the sample card 400 can freely enter and exit the second cavity 112, and after the sample card 400 enters the second cavity 112, each first limiting surface 140 can abut against the corresponding outer wall of the sample card 400, thereby keeping the sample card 400 in a vertical detection posture, for example.
When the first opening 120 is disposed at the top of the darkroom main body 100 and the cavity wall of the cavity 110 is respectively provided with the first guide surface 130 and the first limiting surface 140, the sampling device can be used to realize automatic sampling, deviation correction and limiting. Specifically, sample card 400 is driven by the sampling device and gets into cavity 110, if there is the skew in sample card 400, then can lead through first spigot surface 130, until sample card 400 gets into second cavity 112, the sampling device release sample card 400 this moment, sample card 400 can continue the landing under the condition of being restricted by first spacing face 140, just be in required detection position after the landing to the bottom, and the gesture at this moment is required detection gesture, whole in-process only needs the sampling device to remove and release the action, need not other component cooperations, moreover, the steam generator is simple in structure, and the control is convenient.
In the second embodiment of the present invention, the first guiding surface 130 may also be disposed along the edge of the first opening 120, the upper end is connected to the upper end surface of the darkroom main body 100, and the lower end is connected to the cavity wall of the cavity 110, at this time, the sectional area of the portion of the cavity 110 except the first guiding surface 130 may be kept constant, as shown in fig. 4, for example.
Referring to fig. 5 to 8, a schematic diagram of a third embodiment of the present invention is disclosed, in this embodiment, the darkroom main body 100 further has a detection channel 160 communicated with the cavity 110, the detection channel 160 forms a second opening 150 on an inner wall surface of the darkroom main body 100, wherein the detection channel 160 is disposed corresponding to the detection end 210 of the detection device 200, and has a shape similar to that of the detection end 210, for example, as shown in the drawings, when the detection end 210 is a cylinder, the detection channel 160 is a corresponding circular channel. The detecting channel 160 may be slightly larger than the detecting end 210 so that the detecting end 210 can be inserted into the detecting channel 160, and when the detecting end 210 extends into the detecting channel 160, the distal end surface of the detecting end 210 may be flush with the inner wall surface of the darkroom main body 100 having the second opening 150, or may be lower than the inner wall surface, but usually does not extend out of the inner wall surface, so that the light shielding door 300 achieves a better shielding effect.
Generally speaking, the first opening 120 and the detection channel 160 are disposed on different sides of the chamber body 100, for example, the first opening 120 is disposed on the top of the chamber body 100, and the detection channel 160 is disposed on the side of the chamber body 100, so that the sample-bearing area on the sample card 400 is aligned with the detection end 210 of the detection device 200. The detecting device 200 can be a well-known structure, such as a photomultiplier tube, which includes a main structure and a detecting end 210 connected to one end of the main structure, the detecting end 210 usually has a detecting element sensitive to strong light, such as a photocathode, etc., so that the detecting end 210 should be in a weak light or dark environment as much as possible. The detecting end 210 is disposed through the detecting channel 160, and the main structure is located outside the darkroom main body 100. In order to connect the detection device 200 to the darkroom main body 100, the detection device 200 may further include a mounting housing 220, wherein the mounting housing 220 is a cylindrical structure adapted to the shape of the main body, and has a mounting flange at one end facing the darkroom main body 100, and the mounting flange is provided with a threaded hole. When installed, the main structure is located in the installation housing 220, the detection end 210 extends out of the installation housing 220, and the installation flange is engaged with the outer side surface of the darkroom main body and locked by the threaded fastener. The installation flange and the darkroom main body 100 can be shielded from light by a step surface or by additionally arranging a light shielding pad and the like, so that light is prevented from leaking into the cavity 110.
The darkroom assembly further comprises a light-shielding door 300 and a power member, wherein the light-shielding door 300 cooperates with the power member, the light-shielding door 300 is located in the cavity 110 and connected to the darkroom main body 100, and the power member drives the light-shielding door 300 to move along a direction from the second cavity 112 to the cavity 110 (e.g. a direction from bottom to top in the figure) to open the second opening 150, or to move along a direction from the cavity 110 to the second cavity 112 (e.g. a direction from top to bottom in the figure) to close the second opening 150, so as to close or open the detection channel 160. Referring to fig. 6 and 7, when the light-shielding door 300 closes the second opening 150, the strong light outside the dark room door 500 after being opened can be prevented from damaging the sensitive devices in the detection end 210; when the light shielding door 300 opens the second opening 150, no obstruction exists between the detection end 210 and the sample, and the detection device 200 can detect the sample. The phrase "the light-shielding door 300 closes or opens the second opening 150" in the present application should be understood in a broad sense, and may be that the light-shielding door 300 completely shields the second opening 150, that is, the light-shielding door 300 completely fits to the inner wall surface having the second opening 150, or that a certain gap exists between the light-shielding door 300 and the inner wall surface, the reason for this is that the detection end 210 is located in the cavity 110 of the darkroom main body 100, the wall of the darkroom main body 100 can play a certain role of shading light, even if the dark room door 500 is in an open state, light can enter only from the first opening 120, the amount of entrance is relatively small, when the light-shielding door 300 is in the closed position shown in fig. 7, most of the light can be shielded, therefore, even if the light-shielding door 300 is not attached to the inner wall surface and a certain gap exists between the two, no substantial adverse effect is caused on the sensitive device in the detection end 210.
It can be understood that the light-shielding door 300 and the dark room door 500 can be controlled by a controller, that is, the controller controls the light-shielding door 300 to move from the open position to the closed position before the dark room door 500 needs to be opened; after the darkroom door 500 is completely closed and before detection is needed, the controller controls the light-shielding door 300 to move from the closed position to the open position, so that automatic operation is realized, and errors caused by manual operation are avoided.
The end of the light-shielding door 300 facing the first opening 120, for example, the upper end in fig. 5, 6, and 7, is provided with a second guide surface 310, and when the light-shielding door 300 is in the closed position, the second guide surface 310 can guide the sample card 400 into the second cavity 112, thereby reducing the requirement for the position accuracy when the sample card 400 is inserted. Specifically, the second guide surface 310 is an inclined surface, and the lower end of the second guide surface is connected to the side surface of the light-shielding door 300, and the upper end of the second guide surface is connected to the top surface of the light-shielding door 300. Similar to the first embodiment, the sample card 400 of the present embodiment may also be provided with a third guiding surface 410, and taking fig. 5 as an example, the left side, the right side and the rear side of the sample card 400 are provided with the third guiding surfaces 410, that is, the guiding in the rear direction is realized by the third guiding surface 410 and the sample card 400, and the guiding in the left side, the right side and the rear direction is realized by the second guiding surface 310 and the darkroom main body 100.
As a specific implementation manner of the above scheme, the cavity wall of the cavity 110 is further provided with a first guide surface 130, the first guide surface 130 is disposed on the opposite side, i.e., the front side, of the second guide surface 310, and the guide in the thickness direction of the sample card 400 is implemented by the second guide surface 310 and the first guide surface 130, respectively. Accordingly, the sample card 400 has a large dimension in the width direction, and thus a large area of the third guide surface 410 can be processed, and thus the width direction guide is achieved by the third guide surface 410.
As another specific implementation manner of the above scheme, referring to fig. 5, 8, and 9, the cavity wall of the cavity 110 is further provided with three first guide surfaces 130, the second guide surface 310 and the three first guide surfaces 130 are sequentially arranged along the circumferential direction of the first opening 120, specifically, the three first guide surfaces 130 are respectively located on the left side, the right side, and the front side of the darkroom main body 100, the light shielding door 300 is located on the rear side, the left side and the right side are arranged opposite to the first guide surfaces 130, and the second guide surface 310 is arranged opposite to the front side first guide surfaces 130, so that the sample card 400 can be similarly guided from four directions, namely, the front direction, the rear direction, the left direction, and the right direction.
It can be understood that the inclination angle of each second guide surface 310, and the inclination angles of the second guide surface 310 and the first guide surface 130 may be the same or different. In addition, the first guide surface 130 and the second guide surface 310 may be flat surfaces in the drawing, or may be convex or concave arc surfaces.
