Description

X-ray generators and security inspection equipment Technical Field

[0001] This application belongs to the field of security inspection equipment design technology, specifically relating to a radiation generating device and security inspection equipment. Background Technology

[0002] With the development of science and technology and the improvement of security awareness, security inspection equipment is widely used in places such as train stations, customs, and large-scale event venues. Security inspection equipment can detect items by using side-view illumination. In this case, the X-ray generator is usually located on the side of the security inspection channel, so that the X-rays emitted by the generator enter the channel from the side, thereby detecting items in the channel.

[0003] However, installation errors can easily occur when the X-ray generator is installed on the side of the security checkpoint. This can result in the X-ray generator being too high vertically, creating a gap between the emitted X-ray beam and the conveyor belt of the security equipment, making it difficult to fully illuminate the security checkpoint and thus easily missing items in the security checkpoint. Alternatively, the X-ray generator can be too low vertically, allowing the emitted X-rays to easily illuminate the conveyor belt and create an image on the conveyor belt, which can easily affect the detection effect. Summary of the Invention

[0004] This utility model discloses a radiation generating device and a security inspection device, in order to solve the problem that the radiation generating device involved in the related technology is prone to errors during the installation process, which can easily affect the detection effect.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] In the first aspect, this application discloses a radiation generating device for security inspection equipment, the disclosed radiation generating device including a radiation source, a mounting frame and a driving mechanism;

[0007] The X-ray source and the drive mechanism are both mounted on the mounting frame. The mounting frame is used to connect to the frame of the security inspection equipment. The X-ray source is driven by the drive mechanism. The X-ray source can switch between a locked state and an unlocked state.

[0008] When the radiation source is in the locked state, the radiation source is fixedly connected to the mounting bracket;

[0009] When the X-ray source is in the unlocked state, the X-ray source is slidably connected to the mounting frame, and the driving mechanism is used to drive the X-ray source to slide relative to the mounting frame along a first direction, which is parallel to the bearing direction of the transmission mechanism of the security inspection equipment.

[0010] Secondly, this application discloses a security inspection device, which includes a frame, a transmission mechanism, and the aforementioned X-ray generating device. The frame has a security inspection channel, the transmission mechanism passes through the security inspection channel, and the mounting frame is disposed on one side of the security inspection channel along a second direction and is fixedly connected to the frame. The second direction is perpendicular to the transmission direction and the bearing direction of the transmission mechanism, respectively.

[0011] The technical solution adopted in this utility model can achieve the following technical effects:

[0012] The X-ray generating device disclosed in this application improves the structure of X-ray generating devices related to the relevant technology by setting a drive mechanism and allowing the X-ray source to switch between a locked state and an unlocked state. In the locked state, the X-ray source is fixedly connected to the mounting frame, and in the unlocked state, the X-ray source is slidably connected to the mounting frame. The drive mechanism can drive the X-ray source to slide relative to the mounting frame along a first direction, thereby adjusting the position of the X-ray source in the first direction. At the same time, the first direction is parallel to the bearing direction of the transmission mechanism of the security inspection equipment. This allows the X-ray source to slide relative to the mounting frame along the first direction in the unlocked state by the drive mechanism, thereby adjusting the position of the X-ray source in the bearing direction of the transmission mechanism and thus adjusting the distance between the X-ray source and the transmission mechanism in the bearing direction of the transmission mechanism.

[0013] This structure avoids the problem of errors during the installation of the radiation generator causing the distance between the radiation source and the transmission mechanism in the bearing direction to be too large or too small. This prevents the radiation source from being too close or too far from the transmission belt in the bearing direction of the transmission mechanism, which would make it difficult for the radiation emitted by the source to fully illuminate the security checkpoint, leading to the easy omission of items in the security checkpoint, or the radiation emitted by the source to easily illuminate the transmission belt and image it, thus affecting the detection effect.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] Please refer to Figures 1 to 4. This application discloses a radiation generating device for security inspection equipment. The disclosed radiation generating device includes a radiation source 100, a mounting frame 200, and a drive mechanism 300.

[0031] The radiation source 100 is the core component in the radiation generating device that realizes radiation emission. It is used to emit radiation, as shown in Figures 3 and 4. The radiation emitted by the radiation source 100 can be projected along the dotted lines in Figures 3 and 4. Specifically, the radiation emitted by the radiation source 100 can be X-rays, gamma rays, etc., and this application embodiment does not limit this.

[0032] The mounting frame 200 is the basic component of the radiation generating device, providing mounting positions for other components of the device, including the radiation source 100 and the drive mechanism 300. Furthermore, the mounting frame 200 also forms functional spaces or structures, such as the limiting frame 210 and the second slot 220 described later. Additionally, the mounting frame 200 is used to connect to the frame 400 of the security inspection equipment, allowing the radiation generating device to be fixedly connected to the frame 400 via the mounting frame 200.

[0033] The drive mechanism 300 is used to drive the X-ray source 100 to move. The X-ray source 100 is connected to the drive mechanism 300. The X-ray source 100 can switch between a locked state and an unlocked state, so that when the X-ray source 100 is in the unlocked state, the drive mechanism 300 can drive the X-ray source 100 to move.

[0034] In the specific working process, when the X-ray source 100 is in the locked state, the X-ray source 100 is fixedly connected to the mounting bracket 200, thereby fixing the X-ray source 100. Under this condition, the drive mechanism 300 will not drive the X-ray source 100 to move.

[0035] With the X-ray source 100 in the unlocked state, it is slidably connected to the mounting bracket 200. The drive mechanism 300 drives the X-ray source 100 to slide relative to the mounting bracket 200 along a first direction, thereby adjusting the position of the X-ray source 100 in the first direction. After adjusting the X-ray source 100 to a suitable position in the first direction, it can be switched to the locked state. Furthermore, the first direction is parallel to the bearing direction of the transmission mechanism 500 of the security inspection equipment.

[0036] It should be noted that, referring to Figures 1 to 3, the first direction can be parallel to the direction indicated by the arrow with solid lines in Figures 1 to 3. Moving the X-ray source 100 in the first direction will not change the projection direction of the X-ray emitted by the X-ray source 100.

[0037] The radiation generating device disclosed in this application improves the structure of radiation generating devices related to the relevant technology by setting a drive mechanism 300 and allowing the radiation source 100 to switch between a locked state and an unlocked state. In the locked state, the radiation source 100 is fixedly connected to the mounting frame 200, and in the unlocked state, the radiation source 100 is slidably connected to the mounting frame 200. The drive mechanism 300 can drive the radiation source 100 to slide relative to the mounting frame 200 along a first direction, thereby adjusting the position of the radiation source 100 in the first direction. At the same time, the first direction is parallel to the bearing direction of the transmission mechanism 500 of the security inspection equipment. This allows the radiation source 100 to slide relative to the mounting frame 200 along the first direction in the unlocked state, thereby adjusting the position of the radiation source 100 in the bearing direction of the transmission mechanism 500 and adjusting the distance between the radiation source 100 and the transmission mechanism 500 in the bearing direction of the transmission mechanism 500.

[0038] This structure avoids the problem of errors during the installation of the radiation generator causing the distance between the radiation source 100 and the transmission mechanism 500 in the bearing direction to be too large or too small. This prevents the radiation source 100 from being too close or too far from the transmission belt 510 of the transmission mechanism 500 in the bearing direction, which would make it difficult for the radiation emitted by the radiation source 100 to fully irradiate the security inspection channel 410, leading to the easy omission of items in the security inspection channel 410, or the radiation emitted by the radiation source 100 to easily irradiate the transmission belt 510 and image the transmission belt 510, thus easily affecting the detection effect.

[0039] Meanwhile, in this structure, when the X-ray source 100 is in the locked state, the X-ray source 100 is fixedly connected to the mounting bracket 200. This prevents the drive mechanism 300 from driving the X-ray source 100 to move, thus avoiding the X-ray source 100 from being easily moved after the X-ray source 100 has been adjusted to a suitable position in the first direction and then driven by the drive mechanism 300, which would cause the X-ray source 100 to deviate and affect the detection effect.

[0040] Furthermore, this structure, by setting the X-ray source 100 to slide in the mounting bracket 200 while the X-ray source 100 is in the unlocked state, allows the X-ray source 100 to slide only relative to the mounting bracket 200 in the first direction under the drive of the drive mechanism 300. This limits the range of motion of the X-ray source 100 and prevents the X-ray source 100 from sliding in the second direction described later, which would cause the X-ray source 100 to move closer to or further away from the security checkpoint 410. This would make it easy for the X-ray source to move closer to or further away from items in the security checkpoint 410, thereby easily affecting the clarity of the image and resulting in poor detection results.

[0041] In a further technical solution, the drive mechanism 300 may include a support base 310, which may have a bearing inclined surface 311. The X-ray source 100 may have a support surface 110, and the X-ray source 100 may be supported on the bearing inclined surface 311 by the support surface 110. The support surface 110 may contact the bearing inclined surface 311.

[0042] In the specific operation process, with the X-ray source 100 in the unlocked state, the support base 310 can slide relative to the mounting frame 200 along a second direction. This is used to drive the X-ray source 100 to slide relative to the mounting frame 200 along a first direction through the cooperation between the bearing inclined surface 311 and the support surface 110. During the driving process, the bearing inclined surface 311 and the support surface 110 drive the X-ray source 100 to slide relative to the mounting frame 200 along the first direction through a sliding cooperation. Furthermore, the second direction can be perpendicular to both the transmission direction and the bearing direction of the transmission mechanism 500, allowing the second direction to be perpendicular to the first direction.

[0043] This structure, through the cooperation between the bearing inclined surface 311 and the support surface 110, can stably drive the X-ray source 100 to slide relative to the mounting frame 200 in the first direction, thereby stably adjusting the position of the X-ray source 100 in the first direction. Moreover, this structure is relatively simple and easy to implement, which helps to reduce costs.

[0044] It should be noted that, referring to Figures 1, 3, and 4, the second direction can be parallel to the direction indicated by the arrow with the dashed leader line in Figures 1, 3, and 4.

[0045] In other embodiments, the drive mechanism 300 may also include a rack and pinion mechanism or a belt mechanism, so that when the X-ray source 100 is in the unlocked state, the X-ray source 100 can be driven to slide relative to the mounting bracket 200 in a first direction via the rack and pinion mechanism or the belt mechanism.

[0046] In an optional technical solution, the drive mechanism 300 may further include a drive element 320, and the support base 310 and the drive element 320 can be drivenly connected. During specific operation, when the X-ray source 100 is in the unlocked state, the drive element 320 drives the support base 310 to slide relative to the mounting bracket 200 in a second direction, thereby causing the X-ray source 100 to slide relative to the mounting bracket 200 in a first direction. Specifically, the drive element 320 can drive the support base 310 to slide along the second direction, thereby causing the support base 310 to drive the X-ray source 100 to slide relative to the mounting bracket 200 in the first direction.

[0047] In this structure, the drive unit 320 can indirectly drive the X-ray source 100 to move through the support base 310, so that the X-ray source 100 can be adjusted more conveniently by the drive unit 320.

[0048] In one embodiment, the drive member 320 may be a first screw, which may be positioned and engaged with the mounting bracket 200 in the extension direction of its rotation axis, so that the first screw may rotate about its rotation axis without moving relative to the mounting bracket 200 in the extension direction of its rotation axis. Moreover, the first screw may be threadedly engaged with the support base 310, and the rotation axis of the first screw may be parallel to the second direction.

[0049] In the specific operation, with the radiation source 100 in the unlocked state, the first screw is used to drive the support base 310 to slide relative to the mounting bracket 200 in the second direction. Specifically, the first screw can be a bolt or a screw, and the specific type of the first screw is not limited in this embodiment.

[0050] This structure allows the first screw to engage with the support base 310 via a threaded connection, thereby enabling the support base 310 to slide more precisely relative to the mounting bracket 200 in the second direction. This allows the support base 310 to drive the X-ray source 100 to slide more precisely relative to the mounting bracket 200 in the first direction, which in turn facilitates precise adjustment of the position of the X-ray source 100 in the first direction.

[0051] Of course, in another embodiment, the driving component 320 can be a telescopic rod. The first end of the telescopic rod can be fixedly connected to the mounting frame 200, and the second end can be fixedly connected to the support base 310. This allows the support base 310 to slide relative to the mounting frame 200 in a second direction via the extension and retraction of the telescopic rod, thereby causing the radiation source 100 to slide relative to the mounting frame 200 in a first direction. This structure is relatively simple and easy to implement, thus helping to reduce costs. Specifically, the telescopic rod can be a hydraulic telescopic rod or a pneumatic telescopic rod. This embodiment of the invention does not limit the specific type of telescopic rod.

[0052] Optionally, the drive unit 320 can be a manually driven unit, allowing the drive unit 320 to move manually, thereby reducing costs. Furthermore, the drive mechanism 300 may also include a power source connected to the drive unit 320 to drive its movement, thus facilitating automatic drive and improving drive efficiency. Specifically, the power source can be an electric motor or a hydraulic press; this application embodiment does not limit the specific type of power source.

[0053] In a further technical solution, the drive mechanism 300 may also include a first threaded sleeve 330, which can be fixedly connected to the support base 310. The first threaded sleeve 330 can be fixedly connected to the support base 310 by welding or snap-fitting, and the support base 310 can engage with the first screw threadedly through the first threaded sleeve 330. In this structure, the processing technology of the first threaded sleeve 330 is relatively mature and readily available, thus helping to reduce costs.

[0054] Specifically, the first threaded sleeve 330 can be a nut or a screw, and the specific type of the first threaded sleeve 330 is not limited in the embodiments of this application.

[0055] Of course, in other embodiments, the support 310 may have a threaded hole, so that the support 310 can be threadedly engaged with the first screw through the threaded hole, which helps to simplify the structure and thus improve the installation efficiency.

[0056] In a feasible technical solution, the mounting frame 200 may have a limiting frame 210, and the radiation generating device may further include a limiting member 600, which may be fixed to the mounting frame 200. The limiting member 600 may be fixed to the mounting frame 200 by welding or threaded connection, and the limiting member 600 may be opposite to the limiting frame 210. The second end of the first screw may be threaded into the support base 310, and the first end of the first screw may be rotatably disposed on the limiting member 600. The first end of the first screw may be positioned between the limiting frame 210 and the limiting member 600 in the extension direction of its (i.e., the first screw's) rotation axis. This allows the first end of the first screw to rotate around its (i.e., the first screw's) rotation axis without moving between the limiting frame 210 and the limiting member 600 along its (i.e., the first screw's) rotation axis, thereby positioning the first screw in the extension direction of its rotation axis with the mounting frame 200.

[0057] During installation, the first screw can be first inserted through the limiting member 600, and then the limiting member 600 can be fixed on the mounting bracket 200. This allows the first end of the first screw to be rotatably positioned on the limiting member 600, and the first end of the first screw to be positioned between the limiting frame 210 and the limiting member 600 in the extension direction of its rotation axis. Specifically, the first end of the first screw can be a nut, which is positioned between the limiting frame 210 and the limiting member 600.

[0058] In this embodiment of the application, when the X-ray source 100 is in a locked state, the support base 310 can be in a locked state, and the support base 310 can be fixedly connected to the mounting bracket 200, thereby preventing the support base 310 from sliding along the second direction and easily colliding with the X-ray source 100 or the mounting bracket 200.

[0059] With the X-ray source 100 in the unlocked state, the support base 310 can be in the disengaged state, allowing the support base 310 to slide relative to the mounting bracket 200 in a second direction. This allows the X-ray source 100 to slide along the first direction, adjusting its position in the first direction. After adjusting the X-ray source 100 to a suitable position in the first direction, it can be switched to the locked state, and the support base 310 can be switched to the locked state.

[0060] Furthermore, the radiation generating device may also include a second screw 710 and a second threaded sleeve. One of the mounting bracket 200 and the support base 310 may be provided with a first slotted hole 312, and the other may be provided with a first connecting hole. The first end of the second screw 710 may pass through the first slotted hole 312 and the first connecting hole to connect with the second threaded sleeve, thereby connecting the mounting bracket 200 and the support base 310. The rotation of the second screw 710 or the second threaded sleeve is used to switch the support base 310 between a locked state and an unlocked state, thereby enabling the support base 310 to switch between the locked state and the unlocked state more conveniently.

[0061] Furthermore, the extension direction of the first strip-shaped hole 312 can be parallel to the second direction, thereby guiding the support 310 to slide stably along the second direction through the cooperation of the first strip-shaped hole 312 and the second screw 710, so as to avoid the support 310 being prone to displacement during sliding, which would make it difficult to drive stably. Specifically, the first strip-shaped hole 312 can be an oblong hole or a rectangular hole, and the specific type of the first strip-shaped hole 312 is not limited in the embodiments of this application.

[0062] To improve the reliability of the connection and to better guide the support 310 to slide stably along the second direction, there can be multiple first strip hole 312, first connecting hole, second screw 710 and second threaded sleeve. The first ends of multiple second screws 710 can pass through multiple first strip holes 312 and multiple first connecting holes and be connected to multiple second threaded sleeves respectively.

[0063] In an optional embodiment, the radiation generating device may further include an adapter 800, which can be fixedly connected to the radiation source 100 and to the mounting bracket 200, thereby allowing the radiation source 100 to be connected to the mounting bracket 200 via the adapter 800. During operation, when the radiation source 100 is in a locked state, the radiation source 100 can be fixedly connected to the mounting bracket 200 via the adapter 800. The radiation source 100 can be fixedly connected to the adapter 800 via a threaded connection or riveting, and the adapter 800 can be fixedly connected to the mounting bracket 200, thus allowing the radiation source 100 to be fixedly connected to the mounting bracket 800 via the adapter 800.

[0064] When the X-ray source 100 is in the unlocked state, the X-ray source 100 can be slidably connected to the mounting bracket 200 through the adapter 800. The X-ray source 100 can be fixedly connected to the adapter 800 by means of threaded connection or riveting. The adapter 800 can be slidably connected to the mounting bracket 200, so that the X-ray source 100 and the adapter 800 can slide synchronously, thereby enabling the X-ray source 100 to be slidably connected to the mounting bracket 800 through the adapter 800.

[0065] This structure, through the adapter 800, helps to reduce the complexity of the connection between the radiation source 100 and the mounting bracket 200, thus making it easier to connect the radiation source 100 and the mounting bracket 200.

[0066] Of course, in other embodiments, the radiation source 100 can also be directly connected to the mounting bracket 200, thereby making the structure of the radiation generating device more compact, which in turn helps to reduce the size of the radiation generating device and thus reduce the space occupied by the radiation generating device.

[0067] In a feasible technical solution, the radiation generating device may further include a third screw 720 and a third threaded sleeve. One of the mounting bracket 200 and the adapter 800 may be provided with a second slotted hole 220, and the other may be provided with a second connecting hole. The first end of the third screw 720 may pass through the second slotted hole 220 and the second connecting hole to connect with the third threaded sleeve, thereby connecting the mounting bracket 200 and the adapter 800. The rotation of the third screw 720 or the third threaded sleeve is used to switch the radiation source 100 between a locked state and an unlocked state, thereby enabling a relatively convenient switching of the radiation source 100 between the locked state and the unlocked state.

[0068] Meanwhile, the extension direction of the second strip-shaped hole 220 can be parallel to the first direction, thereby guiding the adapter 800 to slide stably along the first direction through the cooperation of the second strip-shaped hole 220 and the third screw 720. This allows the X-ray source 100 to slide stably along the first direction, avoiding the situation where the adapter 800 is prone to displacement during sliding, making it difficult for the X-ray source 100 to slide stably in the first direction. Specifically, the second strip-shaped hole 220 can be an oblong hole or a rectangular hole; the specific type of the second strip-shaped hole 220 is not limited in this embodiment.

[0069] To improve the reliability of the connection and to better guide the adapter 800 to slide stably along the first direction, there can be multiple second strip holes 220, second connecting holes, third screws 720 and third threaded sleeves. The first ends of the multiple third screws 720 can pass through the multiple second strip holes 220 and multiple second connecting holes respectively and be connected to the multiple third threaded sleeves.

[0070] Based on the X-ray generating device disclosed in the embodiments of this application, this application further discloses a security inspection device, which includes a frame 400, a transmission mechanism 500, and the X-ray generating device described in any of the above embodiments. The frame 400 has a security inspection channel 410, the transmission mechanism 500 passes through the security inspection channel 410, and a mounting bracket 200 is disposed on one side of the security inspection channel 410 along a second direction, and the mounting bracket 200 is fixedly connected to the frame 400. The mounting bracket 200 can be fixedly connected to the frame 400 by means of threaded connection or riveting, and the second direction is perpendicular to the transmission direction and the bearing direction of the transmission mechanism 500, respectively.

[0071] The above embodiments of this utility model focus on describing the differences between the various embodiments. As long as the different optimization features of the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be described in detail here.
