The term "or/and" as used herein includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1 and 2, a schematic structure of a cassette assembly according to an embodiment of the invention is shown. The invention provides a detection box assembly, which is used for being installed on a security inspection machine 30 and collecting information. The security inspection machine 30 comprises a conveying device 31 and a channel sealing plate 32, the detection box assembly comprises a first detection box 10 and a second detection box 20, the first detection box 10 is arranged on the side portion of the channel sealing plate 32, the second detection box 20 is arranged at the bottom of the conveying device 31, detection plates can be contained in the first detection box 10 and the second detection box 20 and used for collecting detected information, and the first detection box 10 and the second detection box 20 of the detection box assembly are arranged in an L-shaped mode due to the fact that the first detection box 10 and the second detection box 20 are arranged at positions on the security inspection machine 30.
In addition, in order to facilitate description of the principle and structural relationship of the cassette assembly of the present invention in the process of mounting or dismounting, the present invention is described using a three-dimensional view angle, in which the direction in which the length direction of the second cassette 20 is located is set as the X-axis direction, the direction in which the length direction of the first cassette 10 is located is set as the Z-axis direction, and the other direction perpendicular to the X-axis direction and the Z-axis direction is set as the Y-axis direction.
As shown in fig. 1 to 8C, the first cassette 10 has a first accommodating chamber 111, the first accommodating chamber 111 for accommodating a probe plate; the first detection box 10 is fixedly arranged at one end of the second detection box 20, the second detection box 20 comprises a second accommodating cavity 211 communicated with the first accommodating cavity 111, and a drawing frame 22 which is positioned in the second accommodating cavity 211 and can reciprocate along the length direction of the second detection box 20; and a locking assembly disposed between the first and second cassette 10 and 20, the locking assembly including a locking piece 24 and an elastic latch 25, the locking piece 24 having an inclined surface 241 and a positioning hole 242 extending from the inclined surface 241, the elastic latch 25 being movable along the inclined surface 241 and inserted into the positioning hole 242 to lock the drawing frame 22 in the second cassette 20.
In one embodiment of the present invention, the locking member 24 is disposed on a side surface of the first detecting case 10, and the elastic latch 25 is disposed on a side surface of the drawing frame 22. Of course, it should be understood by those skilled in the relevant art that in other embodiments of the present invention, the locking member 24 may be disposed on a side of the drawing frame 22, and the elastic latch 25 is disposed on a side of the first detecting box 10, so as to enable the elastic latch 25 to be inserted into the positioning hole 242 of the locking member 24 to lock the drawing frame 22 in the second detecting box 20.
Specifically, as shown in fig. 8A to 8C, when the drawing frame body 22 is inserted into the second receiving chamber 211 along the length direction of the second cassette 20, the elastic latch 25 positioned on the side of the drawing frame body 22 may first contact the inclined surface 241 of the locking member 24, and the latch head of the elastic latch 25 may gradually retract into the body of the elastic latch 25 during the movement along the inclined surface 241, and when the position of the elastic latch 25 reaches the positioning hole 242 of the locking member 24, the latch head of the elastic latch 25 may be inserted into the positioning hole 242 under the elastic action, thereby achieving the position locking of the drawing frame body 22. When the drawing frame 22 needs to be drawn out from the second detecting box 20, only the elastic bolt 25 on the side surface of the drawing frame 22 needs to be drawn out, and the drawing frame 22 is held to gradually draw out the drawing frame 22 from the second detecting box 20 along the length direction of the second detecting box 20, so that the drawing frame 22 can be quickly disassembled.
It should be noted that, in the probe box assembly provided by the present invention, the insertion of the pull frame 22 into the second probe box 20 is performed by the way that the positioning hole 242 of the locking member 24 and the elastic latch 25 are matched and fixed, rather than directly inserting the pull frame 22 into the preset position in the second probe box 20 and then fixing by inserting the elastic latch 25, mainly because the positioning hole 242 and the latch head on the pull frame 22 for installing the matched elastic latch 25 are inconvenient for manual observation, the positioning hole 242 and the latch head on the pull frame 22 are inconvenient to align, which is inconvenient to directly implement by inserting the elastic latch 25 into the positioning hole 242. In addition, by engaging the inclined surface 241 and the positioning hole 242 of the locking member 24 with the elastic latch 25, the drawing frame 22 can be accurately positioned in the depth direction of the drawing frame 22. When the drawing frame 22 is disassembled, the elastic bolt 25 is already installed in the positioning hole 242, and the disassembly can be completed only by pulling out.
In other words, when the drawing frame 22 is moved and inserted into the second receiving chamber 211 along the X-axis direction, the elastic latch 25 located on the side surface of the drawing frame 22 may first contact the inclined surface 241 of the locking member 24, and may move along the inclined surface 241, and guide the elastic latch 25 to move toward the positioning hole 242 until the elastic latch 25 is inserted into the positioning hole 242, thereby fixedly mounting the drawing frame 22 in the second cassette 20 and enabling precise positioning of the drawing frame 22 in the X-axis direction.
As shown in fig. 1 and 4, the second detection box 20 further includes a second detection box body 21 and a guide rail assembly 23, and a second accommodating cavity 211 is formed inside the second detection box body 21; the guide rail assembly 23 includes a first slide rail 231, a middle guide rail 232, and a second slide rail 233, where the first slide rail 231 is fixed on the side surface of the drawing frame 21, the second slide rail 233 is fixed on the inner wall of the side surface of the second detection box 21, guide rail grooves 2321 are respectively provided on two sides of the middle guide rail 232, and the first slide rail 231 and the second slide rail 233 are respectively matched with the guide rail grooves 2321 on two sides of the middle guide rail 232. The three-section guide rail can meet the requirement that the drawing frame body 22 is integrally inserted and pulled out in the X-axis direction, and the horizontality of the drawing frame body 22 can be ensured after the drawing.
Specifically, the guide rail assembly 23 is also provided to support the drawing frame 22 of a certain length horizontally in the X-axis direction, preventing one end of the drawing frame 22 from sagging due to gravity without support during the drawing or inserting of the drawing frame 22. During the process of inserting or extracting the drawing frame 22, the drawing frame 22 slides along the guide rail assembly 23 relative to the second detection box 21, so that the stability and a certain degree of limiting in the drawing process of the drawing frame 22 are realized, wherein the limiting refers to the relative matching of the first slideway 231 of the guide rail assembly 23, the second slideway 233 and the guide rail groove 2321 positioned in the middle guide rail 232, and the drawing frame 22 is not completely separated from the second accommodating cavity 211.
It should be noted that, in other embodiments of the present invention, the guide rail assembly 23 may be implemented as a two-stage guide rail or may be implemented by other means to enable the drawer frame 22 to move along the X-axis direction.
As shown in fig. 1 and 3, one end surface of the drawing frame 22 is provided with at least one guide hole 221, and the inner wall of the end surface of the second detecting box 21 is provided with a guide pin 27 adapted to the guide hole 221.

Accordingly, when two guide holes 221 are provided, two guide pins 27 are provided on the inner wall of the second detection case 21 to be fitted to the guide holes 221.
Specifically, when the drawing frame 22 is inserted into the second accommodation chamber 211, the guide hole 221 on the drawing frame 22 and the guide pin 27 on the second detection case 21 can be engaged with each other, and positioning of the drawing frame 22 along the Y-axis direction can be ensured to prevent the deviation of the ray path in the Y-axis direction and the positioning in the Z-axis direction from being inclined upward or downward in the Z-axis direction to avoid the drawing frame 22 from being inclined upward or downward in the Z-axis direction. The combination of the locking piece 24 and the elastic bolt 25 can realize the accurate positioning of the drawing frame body 22 along the X-axis direction, and the three-section type guide rail assembly 23 can ensure that the drawing frame body 22 keeps horizontal in the X-axis direction, so that the accurate positioning of the drawing frame body 22 in the second detection box body 21 is realized, the accurate positioning of the detection plate in the second detection box body 21 can be further solved, and the influence on the acquisition result of the detection plate is avoided.
As shown in fig. 3, in one embodiment of the present invention, the second detection box 20 may further include a stopper 28, where the stopper 28 is disposed on an inner wall of the end surface of the second detection box body 21.
