Description

Technical Field

[0001] This application belongs to the field of security inspection technology, and specifically relates to a security inspection device. Background Technology

[0002] Security inspection devices are mainly used to inspect items. Top-illuminated integrated security inspection machines are a common type of security inspection device and are widely used in logistics security inspection scenarios.

[0003] In related technologies, top-mounted integrated security inspection machines with built-in conveyors facilitate security inspection processes within logistics lines. In practical applications, when the entire security inspection machine is integrated into a logistics line, the conveyor connects to both the preceding and following logistics lines, allowing objects on the logistics lines to pass through the machine for security inspection. While grooves are provided on the conveyor for installing lateral detectors, placing them beneath the conveyor belt, this installation can damage the conveyor's structure, leading to reduced structural strength. Utility Model Content

[0004] The purpose of this application is to provide a security inspection device that can solve the problem in the related art where opening grooves on conveyors to install transverse detectors can easily lead to a reduction in the structural strength of the conveyor.

[0005] This application provides a security inspection device, which includes a security inspection body, a radiation generating component, a horizontal detector, and a conveyor. The radiation generating component is disposed on the security inspection body, and the horizontal detector is used to detect the radiation emitted by the radiation generating component.

[0006] The security inspection body is mounted on the conveyor, which includes a conveyor belt, a first machine platform and a second machine platform. The first machine platform is equipped with a power component, and the second machine platform is equipped with a transmission component. The conveyor belt is detachably connected to at least one of the power component and the transmission component.

[0007] A clearance space is formed between the first machine and the second machine, and the lateral detector is located within the clearance space.

[0008] In this embodiment of the application, the conveyor includes a first platform and a second platform. A clearance space for accommodating the transverse detector can be formed between the first platform and the second platform. In this way, there is no need to open grooves on the conveyor. On the one hand, it can simplify the assembly operation of the security inspection device and reduce the installation difficulty. On the other hand, it can improve the structural strength and stability of the conveyor without damaging the main structure of the conveyor.

[0009] Furthermore, the first platform is equipped with a power unit, and the second platform with a transmission unit. The conveyor belt is detachably connected to at least one of the power and transmission units. This allows the conveyor to be disassembled into multiple components for separate transport and handling during transportation and handling, effectively reducing the difficulty and cost of these processes. Moreover, during installation, workers can first place the first and second platforms in suitable positions before connecting the conveyor belt, power unit, and transmission unit. This eliminates the need for complex hoisting equipment and a large workforce, further reducing installation difficulty and costs. Attached Figure Description

[0033] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0034] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0035] The security inspection device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0036] refer to Figures 1-12 This application provides a security inspection device that may include a security inspection body 100, a radiation generating assembly (not shown in the figure), a horizontal detector 110, and a conveyor 200. The radiation generating assembly is disposed on the security inspection body 100, and the horizontal detector 110 can be used to detect the radiation emitted by the radiation generating assembly. The security inspection body 100 can be understood as the skeleton or structural frame of the security inspection device, which is a structure that can provide support for the radiation generating assembly, detector, and other components required for security inspection. A security inspection channel can be formed inside the security inspection body 100.

[0037] Among them, such as Figure 2 As shown, the security inspection unit 100 can be mounted on the conveyor 200, which may include a conveyor belt 230, a first machine platform 210, and a second machine platform 220, as shown. Figure 6 As shown, the first machine 210 may be equipped with a power component 212, and the second machine 220 may be equipped with a transmission component 222. The conveyor belt 230 may be detachably connected to at least one of the power component 212 and the transmission component 222. The power component 212 and the transmission component 222 can drive the conveyor belt 230 to move, so as to carry the items through the security inspection body 100, so that the security inspection body 100 can inspect the items.

[0038] In this embodiment, since the conveyor belt 230 is detachably connected to at least one of the power component 212 and the transmission component 222, and the conveyor 200 includes a first platform 210 and a second platform 220, the conveyor 200 can be disassembled into multiple parts during transportation and handling, and transported and handled separately. This effectively reduces the difficulty and cost of transporting and handling the conveyor 200, thereby effectively reducing the difficulty and cost of transporting and handling the entire security inspection device. Furthermore, when installing the conveyor 200, workers can first place the first platform 210 and the second platform 220 in suitable positions, and then connect the conveyor belt 230, the power component 212, and the transmission component 222. This eliminates the need for complex hoisting equipment and a large amount of manpower during the installation process, thus reducing installation difficulty and cost. By setting the conveyor 200 as a segmented structure, the entire security inspection device is more thoroughly modularized, improving the convenience of packaging, transportation, and handling.

[0039] In addition, such as Figure 3 and Figure 5 As shown, a clearance space 280 can be formed between the first machine station 210 and the second machine station 220, and the lateral detector 110 can be located within the clearance space 280. This arrangement eliminates the need for additional slots on the conveyor 200 to install the lateral detector 110, thereby simplifying the assembly of the security inspection device, reducing installation difficulty, and avoiding damage to the main structure of the conveyor 200, thus improving the structural strength and stability of the conveyor 200.

[0040] In an optional embodiment, the first platform 210 and the second platform 220 are detachably connected. This arrangement facilitates the disassembly, assembly, transportation, or handling of the conveyor 200. Furthermore, during the use of the conveyor 200, the first platform 210 and the second platform 220 are less likely to experience relative movement, thereby ensuring that the conveyor belt 230 is less prone to deviation and improving the stability of the conveyor 200 during use.

[0041] In other alternative embodiments, the first machine 210 and the second machine 220 may not be connected.

[0042] In some alternative embodiments, the radiation generating assembly may include a first radiation generating module, that is, the security inspection body 100 may be provided with a first radiation generating module (not shown in the figure), and the first radiation generating module may be disposed on the top (top source) of the security inspection body 100, such as... Figure 4As shown, the horizontal detector 110 can be positioned close to the bottom of the security inspection body 100, and is positioned opposite to the first X-ray generating module so that the horizontal detector 110 can receive the X-rays emitted by the first X-ray generating module. The conveyor belt 230 can pass through the security inspection body 100 and can be located between the first X-ray generating module and the horizontal detector 110. This allows items on the conveyor belt 230 to pass through the space between the first X-ray generating module and the horizontal detector 110, so that the items can be irradiated by X-rays, thereby achieving the detection of the items.

[0043] Since the horizontal detector 110 is installed on the security inspection body 100, there is no need to disassemble the horizontal detector 110 when assembling the security inspection device, and there is no need to calibrate the installation position of the horizontal detector 110. This can ensure the detection accuracy of the horizontal detector 110 and shorten the assembly time of the security inspection device.

[0044] In this embodiment, since the conveyor 200 includes a detachably connected first platform 210, a second platform 220, and a conveyor belt 230, and the lateral detector 110 is mounted on the security inspection body 100, compared to adding a conveyor belt guiding structure to the conveyor 200 and placing the lateral detector 110 within the conveyor belt guiding structure (e.g., setting a raised base on the conveyor 200, creating a groove on the raised base, and installing the lateral detector 110 within the groove), the installation difficulty is reduced and the structure of the conveyor 200 is simplified. Furthermore, it can prevent the increase in the length of the conveyor belt 230 caused by adding a conveyor belt guide structure below the conveyor belt 230, and eliminates the need to cut and re-weld the conveyor belt 230 of the conveyor 200. In addition, compared to opening a groove on the conveyor 200 or the conveyor belt guide structure to install the transverse detector 110 in the groove, the conveyor 200 itself has space for the transverse detector 110, eliminating the need for an additional groove structure and avoiding damage to the main structure of the conveyor 200, thus improving the structural strength and stability of the conveyor 200.

[0045] Optionally, such as Figure 3 As shown, the security inspection body 100 may include a top fixing frame 103, a first frame 101 and a second frame 102. The first frame 101 and the second frame 102 may be located on both sides of the width direction of the conveyor belt 230, respectively. The top end of the first frame 101 and the top end of the second frame 102 may be connected to the top fixing frame 103 on both sides of the width direction of the conveyor belt 230, respectively. The first X-ray generating module may be disposed on the top fixing frame 103.

[0046] like Figure 3As shown, the security inspection body 100 may further include a crossarm reinforcing beam 130, the two ends of which can be connected to the first frame 101 and the second frame 102 respectively, and the lateral detector 110 can be disposed within the crossarm reinforcing beam 130. This arrangement, on the one hand, improves the structural rigidity of the first frame 101 and the second frame 102 to maintain the structural stability of the security inspection body 100 during transportation, relocation, and installation, thereby ensuring high-quality and stable imaging; on the other hand, the crossarm reinforcing beam 130 provides installation space for the lateral detector 110.

[0047] In some alternative embodiments, the radiation generating component may include a second radiation generating module, that is, the security inspection body 100 may also be provided with a second radiation generating module (not shown in the figure), the second radiation generating module may be provided on the second frame 102, that is, the second radiation generating module may serve as a side source.

[0048] In one alternative embodiment, the security inspection device may include a vertical detector (not shown in the figure), which may be disposed within the first frame 101. The vertical detector and the horizontal detector 110 may be independent detectors or combined to form an L-shaped detector. Both the vertical detector and the horizontal detector 110 may be used to detect rays emitted by the first ray generating module and / or the second ray generating module.

[0049] In this embodiment, both the first ray generating module and the second ray generating module can be X-ray generators.

[0050] In alternative implementations, such as Figure 6 , Figure 7 and Figure 12As shown, the conveyor 200 may further include an intermediate support plate 240, which may be located between the first platform 210 and the second platform 220. The intermediate support plate 240 is detachably connected to both the first platform 210 and the second platform 220. The intermediate support plate 240 supports a portion of the conveyor belt 230 and may be located above the clearance space 280. The intermediate support plate 240 provides support for a portion of the conveyor belt 230 to prevent it from sagging into the clearance space 280 under the weight of the items, thus ensuring that the conveyor belt 230 remains flat and stable during movement. Simultaneously, the intermediate support plate 240 also connects the first platform 210 and the second platform 220, preventing relative misalignment of the first platform 210 and the second platform 220 that could cause misalignment or jamming of the conveyor belt 230. For example, the intermediate support plate 240 may be used to support the item conveying section of the conveyor belt 230. Here, the item conveying section of the conveyor belt 230 can be the part of the conveyor belt 230 used to carry items, that is, the item conveying section of the conveyor belt 230 is the part of the conveyor belt 230 located above the power assembly 212 and the transmission assembly 222.

[0051] In other alternative embodiments, the conveyor 200 may also exclude the intermediate support plate 240.

[0052] Optionally, such as Figure 6 and Figure 7 As shown, the intermediate support plate 240 may include a first intermediate support plate 241, a second intermediate support plate 242, and a transmission plate 243. Along the direction from the first machine base 210 to the second machine base 220, the first intermediate support plate 241, the transmission plate 243, and the second intermediate support plate 242 are sequentially connected. The first intermediate support plate 241 can be detachably connected to the first machine base 210, and the second intermediate support plate 242 can be detachably connected to the second machine base 220. Furthermore, in the direction from the intermediate support plate 240 to the clearance space 280, the orthogonal projection of the transmission plate 243 covers the transverse detector 110. This arrangement ensures that the structural strength of the intermediate support plate 240 is maintained while allowing rays to pass through the intermediate support plate 240 and irradiate the transverse detector 110.

[0053] For example, the transmission plate 243 can be made of non-metallic materials, such as plastic, glass, or carbon fiber. The first intermediate support plate 241 and the second intermediate support plate 242 can be made of metallic materials to improve their structural strength; for example, the first intermediate support plate 241 and the second intermediate support plate 242 can be made of stainless steel.

[0054] In other alternative embodiments, the intermediate support plate 240 can be a transmission plate 243, which can be detachably connected to the first machine base 210 and the second machine base 220 respectively.

[0055] In alternative implementations, such as Figure 6 and Figure 11 As shown, the conveyor 200 may further include a connecting reinforcement 270, the two ends of which can be detachably connected to the first platform 210 and the second platform 220 respectively. Furthermore, the transverse detector 110 can be located between the conveyor belt 230 and the connecting reinforcement 270. This arrangement further improves the connection stability of the first platform 210 and the second platform 220, thereby further preventing relative misalignment between the first platform 210 and the second platform 220.

[0056] Optionally, the connecting reinforcement 270 may be located within the clearance space 280.

[0057] Optionally, the conveyor 200 may include at least two connecting reinforcements 270, each connecting reinforcement 270 being spaced apart along the width direction of the conveyor belt 230, and both ends of each connecting reinforcement 270 being detachably connected to the first machine base 210 and the second machine base 220, respectively. For example, the at least two connecting reinforcements 270 may include a first connecting reinforcement 2701 and a second connecting reinforcement 2702, which may be disposed close to both sides of the conveyor belt 230 in its width direction.

[0058] In other alternative embodiments, the conveyor 200 may also exclude the connecting reinforcement 270.

[0059] Optionally, such as Figure 6 As shown, a clearance groove 271 can be provided on the side of the connecting reinforcement 270 near the conveyor belt 230. The clearance groove 271 can be used to avoid the transverse detector 110. This arrangement can prevent the connecting reinforcement 270 from interfering with the transverse detector 110, thus preventing the conveyor 200 from being assembled with the security inspection body 100.

[0060] Of course, the connecting reinforcement 270 may not have the clearance groove 271. For example, the vertical distance between the connecting reinforcement 270 and the horizontal detector 110 can be increased.

[0061] In alternative implementations, such as Figure 6As shown, the conveyor 200 may further include a first support plate 250 and a second support plate 260. The first support plate 250 can be detachably connected to the first machine base 210 and can be used to support a portion of the conveyor belt 230. The second support plate 260 can be detachably connected to the second machine base 220 and can be used to support a portion of the conveyor belt 230. The first support plate 250 and the second support plate 260 can further support the conveyor belt 230 to further prevent the conveyor belt 230 from sagging under the weight of the items, thereby further ensuring that the conveyor belt 230 remains flat and stable during movement. Furthermore, since the first support plate 250 is detachably connected to the first machine base 210 and the second support plate 260 is detachably connected to the second machine base 220, the conveyor 200 can be transported and handled separately during transport and handling, which helps to reduce the difficulty of transport and handling. It also facilitates the disassembly and assembly of the conveyor belt 230 and the maintenance and repair of the structures inside the first machine base 210 and the second machine base 220.

[0062] In other alternative embodiments, the conveyor 200 may also exclude the first support plate 250 and the second support plate 260.

[0063] In some alternative embodiments, the conveyor 200 may further include a first support roller (not shown in the figure), which is rotatably connected to the first machine base 210. The first support roller may be disposed below the first support plate 250 and may be used to support the conveyor belt 230 located below the first support plate 250. In this way, the conveyor belt 230 can be guided on the one hand, and the tension of the conveyor belt 230 can be improved on the other hand, thereby improving the stability of the conveyor belt 230 operation.

[0064] like Figure 7 As shown, the conveyor 200 may also include a second support roller 223, which can be rotatably connected to the second machine base 220. The second support roller 223 can be disposed below the second support plate 260 and can be used to support the conveyor belt 230 located below the second support plate 260. In this way, on the one hand, it can guide the conveyor belt 230, and on the other hand, it can improve the tension of the conveyor belt 230, thereby improving the stability of the conveyor belt 230 operation.

[0065] In this embodiment, the conveyor 200 may include a plurality of first support rollers and a plurality of second support rollers 223. Along the direction from the first machine platform 210 to the second machine platform 220, i.e., along the conveying direction of the conveyor belt 230, the first support rollers are spaced apart, and the second support rollers 223 are spaced apart. This further improves the tension of the conveyor belt 230.

[0066] Optionally, such as Figure 6 As shown, the first support plate 250 may include at least two first trays 251, each first tray 251 being sequentially distributed along the direction from the first machine base 210 to the second machine base 220, and each first tray 251 being detachably connected to the first machine base 210. This configuration allows the operator to sequentially disassemble and assemble each first tray 251 when assembling or disassembling the first support plate 250, effectively reducing the difficulty of disassembling and assembling the first support plate 250.

[0067] like Figure 6 , Figure 7 and Figure 12 As shown, the second support plate 260 may include at least two second trays 261, each second tray 261 being sequentially distributed along the direction from the first machine base 210 to the second machine base 220, and each second tray 261 being detachably connected to the second machine base 220. This configuration allows the operator to sequentially disassemble and assemble each second tray 261 when assembling or disassembling the second support plate 260, effectively reducing the difficulty of disassembling and assembling the second support plate 260.

[0068] Of course, the first support plate 250 can also be a one-piece structure, and the second support plate 260 can also be a one-piece structure.

[0069] In some alternative embodiments, the first machine base 210 is detachably connected to two first baffles. The two first baffles can be connected to the two sides of the first machine base 210 in the width direction of the conveyor belt 230, respectively. In the width direction of the conveyor belt 230, the two first baffles can respectively limit the movement of the conveyor belt 230, thereby preventing the conveyor belt 230 from deviating during operation.

[0070] The second machine base 220 is detachably connected to two second baffles. The two second baffles can be connected to the two sides of the second machine base 220 in the width direction of the conveyor belt 230, respectively. In the width direction of the conveyor belt 230, the two second baffles can respectively limit the movement of the conveyor belt 230, thus preventing the conveyor belt 230 from deviating during operation.

[0071] Optionally, the first support plate 250 described above can be detachably connected to two first baffles on both sides of the conveyor belt 230 in the width direction. Similarly, the second support plate 260 described above can be detachably connected to two second baffles on both sides of the conveyor belt 230 in the width direction. Alternatively, the first support plate 250 can also be detachably connected to the first machine base 210, and the second support plate 260 can be detachably connected to the second machine base 220.

[0072] In optional embodiments of this application, such as Figures 1-3As shown, the security inspection device may further include a first protective shield 300 and a second protective shield 400. Both the first and second protective shields 300 and 400 can be detachably connected to the security inspection body 100. The first protective shield 300 can cover at least a portion of the first machine base 210, and the second protective shield 400 can cover at least a portion of the second machine base 220. The first and second protective shields 300 can reduce interference from the external environment on the detection results, such as reducing interference from external light on X-rays, which helps improve the accuracy of the detection. Simultaneously, since the first and second protective shields 300 and 400 are detachably connected to the security inspection body 100, they can be transported and handled separately during transport and handling, effectively reducing the difficulty and cost of transporting and handling the security inspection device.

[0073] In other alternative embodiments, the first protective shield 300 and the second protective shield 400 may also be non-detachably connected to the security inspection body 100.

[0074] In alternative implementations, such as Figure 3 As shown, the bottom of the security inspection body 100 can be connected to at least two first legs 120. The first legs 120 can be used to support the security inspection body 100, and the first legs 120 can be a liftable structure. By adjusting the height of the first legs 120, the height of the security inspection body 100 can be adjusted so that the height of the security inspection device is adapted to the height of the conveyor 200.

[0075] Of course, the first leg 120 may not be a height-adjustable structure, that is, the height of the first leg 120 cannot be adjusted.

[0076] In this embodiment, the bottom of the security inspection body 100 is connected to four first legs 120, which are distributed at the four corners of the bottom of the security inspection body 100 to improve the stability of the security inspection body 100.

[0077] Optionally, such as Figure 3 As shown, the bottom of the first platform 210 can be connected to at least two second legs 211, which can be used to support the first platform 210 and can be height-adjustable. The bottom of the second platform 220 can be connected to at least two third legs 221, which can be used to support the second platform 220 and can also be height-adjustable. With this configuration, by adjusting the heights of the second legs 211 and the third legs 221 respectively, the heights of the first platform 210 and the second platform 220 can be adjusted respectively, so that the height of the conveyor 200 can be adapted to the heights of the two logistics lines.

[0078] Of course, the second leg 211 may not be a height-adjustable structure, meaning the height of the second leg 211 cannot be adjusted. The third leg 221 may also not be a height-adjustable structure, meaning the height of the third leg 221 cannot be adjusted.

[0079] In this embodiment, the bottom of the first machine platform 210 is connected to four second legs 211, which can be located at the four corners of the bottom of the first machine platform 210. The bottom of the second machine platform 220 is connected to four third legs 221, which can be located at the four corners of the bottom of the second machine platform 220.

[0080] Optionally, such as Figure 3 As shown, at least two fourth legs 310 can be connected to the bottom of the first protective shield 300. The fourth legs 310 can be used to support the first protective shield 300, and the fourth legs 310 are liftable structures. With this configuration, the height of the first protective shield 300 can be adjusted by adjusting the height of the fourth legs 310, so that the height of the first protective shield 300 can be adapted to the height of the conveyor 200.

[0081] like Figure 3 As shown, at least two fifth legs 410 can be connected to the bottom of the second protective shield 400. The fifth legs 410 can be used to support the second protective shield 400 and can be a liftable structure. With this configuration, the height of the second protective shield 400 can be adjusted to match the height of the conveyor 200.

[0082] Of course, the fourth leg 310 and the fifth leg 410 may not be height-adjustable structures, that is, the height of the fourth leg 310 and the fifth leg 410 cannot be adjusted.

[0083] In this embodiment, the bottom of the first protective shield 300 is connected to two fourth legs 310, which can be located on both sides of the first machine platform 210 in the width direction of the conveyor belt 230. The bottom of the second protective shield 400 is connected to two fifth legs 410, which can be located on both sides of the second machine platform 220 in the width direction of the conveyor belt 230.

[0084] In some alternative embodiments, the structures of the first leg 120, the second leg 211, the third leg 221, the fourth leg 310, and the fifth leg 410 can be identical. Specifically, each leg may include a fixing member, an adjusting member, and a foot. The top of the foot can be connected to the adjusting member, and the fixing member and the adjusting member are slidably connected. For example, the fixing member has an inner cavity, and a portion of the adjusting member is slidably disposed within the inner cavity, so that the leg forms a telescopic structure. The height of the leg can be adjusted by adjusting the relative position of the adjusting member and the fixing member. It should be noted that the leg here can refer to any one of the first leg 120, the second leg 211, the third leg 221, the fourth leg 310, and the fifth leg 410 described above.

[0085] The outrigger may also include a connector, which connects the fixing member and the adjusting member, fixing the fixing member and the adjusting member relative to each other to keep the outrigger at the desired height. For example, the fixing member has multiple first connecting holes, each communicating with an inner cavity, and the first connecting holes may be spaced apart along the length of the outrigger. The adjusting member may have multiple second connecting holes, also spaced apart along the length of the outrigger, and at least some of the second connecting holes may be opposite to the first connecting holes. The connector can pass through the first connecting holes and connect with the second connecting holes to fix the fixing member and the adjusting member. Here, the connector may be a bolt, and the first connecting holes may be threaded holes that engage with the bolt threads.

[0086] When the height of the outrigger needs to be adjusted, the connector can be disengaged from the second connecting hole, and the fixing member and the adjusting member can be slid relative to each other to adjust the outrigger to the required height. Then, the connector can be inserted into the second connecting hole to fix the fixing member and the adjusting member, thereby keeping the outrigger at the required height.

[0087] In this embodiment of the application, when installing the security inspection device, the security inspection body 100 can first be fixed at the required position on the logistics line, and the height of the first support leg 120 can be adjusted; then, as... Figures 9-12 As shown, the first machine platform 210 and the second machine platform 220, equipped with conveyor belt 230, are sequentially pushed into the channel of the security inspection body 100, and the heights of the second support leg 211 and the third support leg 221 are adjusted so that the heights of the first machine platform 210 and the second machine platform 220 are consistent and adapted to the heights of the two logistics lines in front and behind. Figure 1As shown, the conveyor 200 is docked with the first logistics line 500 and the second logistics line 600 respectively. The first machine platform 210 and the second machine platform 220 are then connected via the first connecting reinforcement 2701 and the second connecting reinforcement 2702, at which point the transverse detector 110 is positioned between the first machine platform 210 and the second machine platform 220. The conveyor belt 230 is then connected to the power assembly 212 and laid flat on the conveyor 200, i.e., laid flat on the first machine platform 210 and the second machine platform 220. The intermediate support plate 240, the driven roller, the first support plate 250, and the second support plate 260 are sequentially inserted into the conveyor belt 230. The intermediate support plate 240 is then connected to the first machine platform 210 and the second machine platform 220, the driven roller and the second support plate 260 are connected to the second machine platform 220, and the first support plate 250 is connected to the first machine platform 210. Afterwards, the conveyor belt 230 is adjusted for misalignment. Finally, the first protective shield 300 and the second protective shield 400 are respectively assembled to both sides of the security inspection body 100 in the conveying direction of the conveyor belt 230.

[0088] In this embodiment, the conveyor belt 230 can be detachably connected to the transmission assembly 222. This is possible when the security inspection device leaves the factory. Figure 8 As shown, the conveyor belt 230 is connected to the power assembly 212 via a transmission. The power assembly 212 may include a drive roller and a drive motor for driving the drive roller to rotate. The drive motor can be connected to the first machine base 210, and the drive roller can be rotatably connected to the first machine base 210. The conveyor belt 230 can be fitted over the drive roller, and the rotation of the drive roller can drive the conveyor belt 230 to move. The transmission assembly 222 may include a drive roller, which can be detachably connected to the second machine base 220 and can rotate relative to the second machine base 220. The conveyor belt 230 can be fitted over the drive roller.
