Technical Field

[0001] This invention relates to the field of CT technology, and more particularly to a detector mounting bracket. Background Technology

[0002] Existing CT scanner detector mounting brackets typically consist of two sections: one horizontally positioned relative to the scanner's base, and the other vertically positioned relative to the base. These two sections are mostly integrated, straight-rod-type structures. During installation, a minimum of the bracket's length must be reserved on the side of the equipment to ensure the horizontally positioned detector bracket can be smoothly inserted into the scanner. However, given the close arrangement of various devices within the security area, assembling and maintaining existing detector mounting brackets is extremely inconvenient. Summary of the Invention

[0003] The purpose of this invention is to provide a detector mounting bracket that solves the technical problem of limited installation space around CT security inspection machines and inconvenient disassembly and assembly of detector mounting brackets in the prior art.

[0004] To achieve this objective, the present invention adopts the following technical solution: A detector mounting bracket for providing precise mounting positions for various detectors within a security inspection device, comprising: The longitudinal mounting bracket extends vertically relative to the security inspection equipment and is detachably connected to the base frame of the security inspection machine; The horizontal mounting bracket extends horizontally compared to the security inspection equipment and can be detachably connected to the base frame of the security inspection machine; The horizontal mounting frame includes at least two sub-segments, which are connected end to end and arranged sequentially, and are movably connected to each other; each sub-segment is detachably connected to the base frame of the security inspection machine.

[0005] Preferably, it also includes a fastener that secures each of the segments in a predetermined orientation.

[0006] Preferably, each of the sub-segments is movably connected by a chain or link.

[0008] Preferably, in the insertion area, the sliding direction of the two mating sliding surfaces is the same as or relatively inclined to the extending direction of the transverse mounting bracket; In the mating area, the extending directions of the two mating surfaces are perpendicular to the extending direction of the transverse mounting bracket.

[0009] Preferably, in the insertion area, the sliding direction of the two mating sliding surfaces is perpendicular to or inclined to the extension direction of the transverse mounting bracket. In the mating area, the two mating surfaces extend in the same direction as the transverse mounting bracket.

[0010] Preferably, in the mating area, at least a partial area of ​​the two mating surfaces has an extension direction that is relatively inclined to the extension direction of the transverse mounting bracket.

[0011] Preferably, in the mating area, the two mating surfaces have at least two local areas where the extending direction of the mating surfaces in these two areas is inclined relative to the extending direction of the transverse mounting bracket, and the two inclined surfaces are arranged opposite to each other.

[0013] Preferably, in two adjacent sub-segments, one sub-segment is fixedly provided with a limiting block at its eccentric position, and the other sub-segment is provided with a limiting groove opposite to it. Once the limiting block is engaged in the limiting groove, it prevents the two sub-segments from continuing to rotate; the fastener is tightened to prevent the limiting block from coming out of the limiting groove.

[0014] Preferably, in two adjacent sub-segments, the rotating shaft passes through one of the sub-segments, and a sliding groove is provided on the other sub-segment. One end of the sliding groove is close to the connecting end of the sub-segment, and the other end of the sliding groove extends in the length direction of the sub-segment.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0021] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0023] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0024] like Figure 1-9 As shown, this embodiment of the invention discloses a detector mounting bracket for providing precise mounting positions for various detectors within a security inspection device, comprising: The longitudinal mounting bracket 1 extends in the height direction relative to the security inspection equipment and is detachably connected to the base frame of the security inspection machine; The horizontal mounting bracket 2 extends horizontally relative to the security inspection equipment and is detachably connected to the base frame of the security inspection machine; The horizontal mounting frame 2 includes at least two sub-segments 21, which are connected end to end and arranged in sequence, and are movably connected to each other; each sub-segment 21 is detachably connected to the base frame of the security inspection machine.

[0025] The design of this invention features a longitudinal mounting frame 1 that can be vertically moved and fixed to a designated position on the security inspection machine. The transverse mounting frame 2 has movably connected sub-segments 21, which are detachably connected to each other or can be relatively tilted at a certain angle. When installing the transverse mounting frame 2, each sub-segment 21 can be inserted into the frame of the security inspection machine one by one. The sub-segments 21 are movably connected to each other without interfering with each other during insertion; only the insertion of a single sub-segment 21 is required. Compared to the existing integrated transverse connecting frame design, the required installation space is significantly smaller, resulting in significant benefits in the installation and maintenance of security inspection equipment.

[0026] like Figure 1-4 As shown In Example 1, each segment 21 is first fixed to each other and then installed on the security inspection machine. The segment 21 is inserted horizontally, vertically, or at an angle.

[0027] With segment 21 placed horizontally, the sliding surface of the insertion area 211 is U-shaped, with the opening of the U-shaped sliding surface facing upwards. The bottom plane of the U-shaped sliding surface can be a flat plane, with a right-angle bend between the bottom plane and the side wall. The mating surface of the mating area 212 is located on the side wall of segment 21, and the mating surface is vertically inclined. Two adjacent segments 21 can slide and mate horizontally, vertically, or relatively inclined until the sliding surfaces of the insertion areas 211 and the mating surfaces of the mating areas 212 are completely aligned. The fastener 22 uses bolts to secure the two adjacent segments 21 in place.

[0028] The sliding surface of the insertion area 211 adopts a U-shaped groove structure with an open top, which allows the sub-segments 21 to be inserted and assembled at multiple angles for easy assembly. The mating surface of the docking area 212 is inclined. During installation, the inserted sub-segment 21 can slide a certain distance further than the top of the inclined mating surface in the horizontal direction. Under its own weight, the sub-segment 21 will slide down along the inclined mating surface until the two mating parts are completely fitted, which makes it easy for the staff to splice the two adjacent sub-segments 21 into place.

[0029] like Figure 9 As shown, In Example 2, each segment 21 is first fixed to each other and then installed onto the security inspection machine, wherein the segment 21 is vertically inserted. With segment 21 placed horizontally, the sliding surface of the insertion area 211 is U-shaped, with the opening of the U-shaped sliding surface facing upwards. One side of the insertion area 211 is a cross-section in the thickness direction of the sidewall of segment 21, and the other is a protrusion in the thickness direction of the sidewall of an adjacent segment 21. The mating surface of the mating area 212 is located on the sidewall of segment 21, and the mating surface is generally arc-shaped or V-shaped. In two adjacent segments 21, one segment 21 has an arc-shaped or V-shaped protrusion on its sidewall, and the other segment 21 has a groove matching the protrusion at a corresponding position. During installation, the segment 21 with the arc-shaped or V-shaped protrusion is lifted above the other segment 21, and gradually slid in under the constraint of the sliding surface until the arc-shaped or V-shaped protrusion is completely engaged in the matching groove on the other segment 21. The fastener 22 uses bolts to secure the two adjacent segments 21 in place.

[0030] The specific positions of the arc-shaped or V-shaped protrusions and their corresponding grooves are set according to the specific dimensions of the U-shaped sliding surface, so that when the arc-shaped or V-shaped protrusions on the sub-segment 21 are fully engaged, the two sliding surfaces are perfectly aligned. The perfect alignment of the two U-shaped sliding surfaces ensures that the two mating sub-segments 21 are on the same straight line. The cooperation between the arc-shaped or V-shaped protrusions and the corresponding grooves ensures that the two mating sub-segments 21 meet the design requirements in their length direction. The mating surfaces of the arc-shaped or V-shaped protrusions and the corresponding grooves are the mating surfaces of the mating areas 212 of the two sub-segments 21. In this embodiment, the splicing and sliding of the sub-segments 21 and the alignment of the mating surfaces can be completed using the weight of the sub-segments 21 themselves, making installation convenient and labor-saving, and ensuring high alignment accuracy for each sub-segment 21.

[0031] Optionally, the height of the arc-shaped or V-shaped protrusion is less than the depth of its matching groove. During assembly, it is only necessary to ensure that the center line of the protrusion coincides with the center line of the groove, without having to ensure that the top of the protrusion is flush with the opening of the groove, effectively reducing the requirements for machining accuracy.

[0032] like Figure 5-8 As shown In Example 3, each segment 21 is first fixed to each other and then installed onto the security inspection machine, wherein two adjacent segments 21 are rotatably connected. The sub-segment 21 is generally rectangular with an open top. The rotating shaft 23 is divided into two sections, fixedly mounted on the inner or outer side wall of one sub-segment 21. The axes of the two rotating shafts 23 are on the same straight line. Both rotating shafts 23 simultaneously pass through the sub-segment 21 of another adjacent transverse mounting frame 2, allowing the passed-through sub-segment 21 to rotate freely around the rotating shaft 23. Positioning through holes are provided on the walls of the sub-segments 21 of the two transverse mounting frames 2. Bolts are used as fixing members 22. After the two sub-segments 21 rotate to a predetermined angle, the through holes on the two sub-segments 21 overlap, at which point the bolts can be inserted to fix the two sub-segments 21 together.

[0033] During the assembly process, after the first segment 21 is inserted into the security inspection machine, the second segment 21 is rotated to a predetermined angle. The relative angle between the two segments 21 is locked by the fastener 22. After locking, the insertion continues. After the second segment 21 is inserted, the subsequent segments 21 repeat the previous operation in sequence. All segments 21 are fixed to each other and after being inserted into the security inspection machine, the horizontal mounting frame 2 composed of the segments 21 is fixed to the designated position on the base frame of the security inspection machine.

[0034] When performing the disassembly operation, first remove the horizontal mounting bracket 2 from the frame of the security inspection machine, pull out a section 21, remove a fixing piece 22 that limits the rotation angle of the section 21, and the pulled-out section 21 can rotate freely. In the case of limited space, it will not hinder the subsequent removal process of the section 21.

[0035] The locking state between two adjacent sub-segments 21 can be switched by removing and installing the fixing piece 22, which is convenient to operate. The rotating shaft 23 locks all positions of the two adjacent sub-segments 21 except for the rotational movement. Only the fixing piece 22 is needed to lock the last rotational movement. The amount of movement to be adjusted is less, and the positioning accuracy of each sub-segment 21 after fixing is relatively high.

[0036] In Example 4, the segments 21 are not fixed relative to each other, but are fixedly connected to the frame of the security inspection machine.

[0037] Each segment 21 is connected to the others by chains, links, etc., and there is no need for fasteners 22 to fix adjacent segments 21 relative to each other.

[0038] During assembly, the next segment 21 is used to push the previous segment 21 into the designated installation position inside the security inspection machine. After all segments 21 have been pushed into their designated positions, each segment 21 is then fixedly connected to the base frame of the security inspection machine. The relative positions of each segment 21 before being pushed into the security inspection machine are adjustable. It is only necessary to ensure that a single segment 21 can be inserted into the security inspection machine; other segments 21 can be freely rotated and folded without obstructing the normal insertion of the horizontal mounting bracket 2, and no excessive space is required.

[0039] During disassembly, each segment 21 is first removed from the base frame of the security inspection machine. The outermost segment 21 is pulled, and the internal segments 21 are connected together by chains and connecting rods and pulled out one by one. During the process of being pulled out, the segments 21 do not interfere with each other. It is only necessary to ensure that a single segment 21 can be pulled out, without the need for excessive space.

[0040] This can effectively avoid the problem of insufficient precision in the docking and fixing between the two segments 21, which leads to errors in the subsequent positioning angles of each detector.

[0041] As an optional embodiment of the present invention, it also includes a fastener 22, which fastens and fixes each segment 21 in a predetermined orientation.

[0042] Specifically, each segment 21 is movably connected. One segment 21 is inserted horizontally into the security scanner, and then the next segment 21 is fixed to the segment 21 inserted into the security scanner using the fastener 22. Then, the two fixed segments 21 are inserted horizontally into the security scanner, and so on, fixing the subsequent segments 21 horizontally into the scanner. When disassembling, first pull out one segment 21 of the horizontal mounting bracket 2, loosen the fastener 22 between the two segments 21, remove or bend the exposed segment 21, and then pull out the subsequent segments 21. In this way, the side of the scanner does not need to reserve or clear an installation space at least equal to the length of the horizontal mounting bracket 2. It only needs to ensure that each movably connected segment 21 can be inserted horizontally normally, and the disassembly and assembly of the detector mounting bracket can be completed in a smaller space.

[0043] As an optional embodiment of the present invention, each sub-segment 21 is detachably connected to each other, and the sub-segment 21 is provided with a plug-in area 211 and a docking area 212; The insertion area 211 of two adjacent sub-segments 21 has at least one pair of sliding surfaces that slide relative to each other; The docking areas 212 of two adjacent sub-segments 21 have at least one pair of mating surfaces; With the insertion area 211, the docking area 212 and the fastener 22 working together to limit the movement, the two adjacent sub-segments 21 are fixed.

[0044] Optionally, in the insertion area, the sliding direction of the two mating sliding surfaces is the same as or relatively inclined to the extending direction of the transverse mounting bracket 2. In the docking area, the extending directions of the two mating surfaces are perpendicular to the extending direction of the transverse mounting bracket 2.

[0045] Optionally, in the insertion area, the sliding direction of the two mating sliding surfaces is perpendicular to or inclined to the extending direction of the transverse mounting bracket 2. In the docking area, the extension direction of the two mating surfaces is the same as the extension direction of the transverse mounting bracket 2.

[0046] Optionally, at least a local area of ​​the two mating surfaces has an extension direction that is relatively inclined to the extension direction of the transverse mounting bracket 2. In use, the segment 21 to be installed is moved a suitable distance above the inclined mating surface, allowing the segment 21 to slide down the inclined mating surface under its own weight, ensuring that the two mating surfaces fit tightly together, thereby improving the relative positional accuracy between the two segments 21.

[0047] Optionally, the two mating surfaces have at least two local areas where the extension direction of the mating surfaces in these two areas is inclined relative to the extension direction of the transverse mounting bracket 2, and the two inclined surfaces are arranged opposite each other. Referring to the case of a single inclined mating surface, after the sub-segment 21 slides to the bottom of the single inclined mating surface, improper operation may cause the sub-segment 21 to move in the direction of separation of the mating surfaces, resulting in a gap between the mating surfaces of the two sub-segments 21; however, with the design of two inclined mating surfaces, under the action of the sub-segment 21's own gravity, the two mating surfaces are limited in two directions in real time, which can ensure that the mating surfaces remain in a close fit.

[0048] As an optional embodiment of the present invention, each sub-segment 21 is rotatably connected to each other, and a rotation shaft 23 is provided between two adjacent sub-segments 21; Two adjacent segments 21 are rotatably connected around the rotating shaft 23; the fixing member 22 is eccentrically set relative to the rotating shaft 23 to lock the relative angle between the two adjacent segments 21.

[0049] Optionally, a limiting block 213 is fixedly provided at the eccentric position of one sub-segment 21, and a limiting groove 214 is provided opposite to the other sub-segment 21; wherein, the limiting block 213 and the limiting groove 214 are preferably arc-shaped.

[0050] When the limiting block 213 is engaged in the limiting groove 214, it prevents the two sub-segments 21 from continuing to rotate. Through holes are opened at designated positions on the two adjacent sub-segments 21. When the limiting block 213 is fully engaged in the limiting groove 214, the through holes on the two adjacent sub-segments 21 coincide with each other. The fixing member 22 is a bolt. The bolt is inserted into the through hole and tightened to prevent the limiting block 213 from coming out of the limiting groove 214, thus completing the fixing of the two adjacent sub-segments 21.

[0051] As an optional embodiment of the present invention, in two adjacent sub-segments 21, the rotating shaft 23 passes through one sub-segment 21, and the other sub-segment 21 is provided with a sliding groove 217. One end of the sliding groove 217 is close to the connecting end of the sub-segment 21, and the other end of the sliding groove 217 extends in the length direction of the sub-segment 21. The connecting end of the sub-segment 21 is the end of the sub-segment 21 that is close to the other adjacent sub-segment 21.

[0052] When the rotating shaft 23 slides to one end of the sliding groove 217 near the end of the sub-segment 21, the rotating shaft 23 can rotate freely around its own central axis within the sliding groove 217.

[0053] The relative positions of two adjacent sub-segments 21 are locked by the rotating shaft 23 in conjunction with the fixing component 22. This places a large load on the rotating shaft 23, which also needs to act as a bearing for the sub-segments 21. Over time, wear on the rotating shaft 23 can lead to a decrease in the assembly accuracy between the two adjacent sub-segments 21. In this solution, the function of the rotating shaft 23 is separated. When the rotating shaft 23 is located at the end of the sliding groove 217 (near the end of the connecting section of the sub-segment 21), it acts as a bearing for the sub-segment 21. When the rotating shaft 23 slides within the groove, it acts as a sliding limit block 213. Sliding the rotating shaft 23 inward along the groove increases the overlap area of ​​the two adjacent sub-segments 21. Two through holes are opened within the overlap area of ​​the two sub-segments 21, and at least two bolts are inserted through these holes to limit the movement of the two sub-segments 21. This reduces the load on the rotating shaft 23 and extends the service life of the equipment.

[0054] As an optional embodiment of the present invention, the fastener 22 includes at least a bolt; at least one bolt is provided between each adjacent sub-segment 21, and the bolt passes through both adjacent sub-segments 21 and is fastened. Alternatively, limiting components such as limiting pins, rivets, and buckles may be used to limit the movement of the two adjacent sub-segments 21.

[0055] As an optional embodiment of the present invention, in two adjacent sub-segments 21, at least one first protrusion is provided on the inner side of one sub-segment 21, and a corresponding second protrusion is provided on the inner side of the other sub-segment 21; and through holes are provided on the first protrusion and the second protrusion respectively. When two adjacent segments 21 are in a predetermined position, the first boss and the second boss overlap each other, and the fastener 22 passes through the through holes on the first boss and the second boss to fix the two segments 21.

[0056] like Figure 1-4 As shown, specifically, the horizontal mounting frame 2 includes three sub-sections 21. The structures of the interfaces at both ends of the middle sub-section 21 are mirror images of each other; the structures of the sub-sections 21 on both sides near the interface of the middle sub-section 21 are the same, which facilitates mass production; the assembly methods at both locations are the same, which facilitates the disassembly and assembly of the equipment.

[0057] The sliding surface of the insertion area 211 is located at the bottom of each sub-segment 21. At the bottom port of the middle sub-segment 21, a sliding plate is provided. The extended surface of the sliding plate is parallel to the bottom plane of the sub-segment 21, and the sliding plate protrudes upwards relative to the bottom surface of the sub-segment 21. The lower plane of the sliding plate forms the sliding surface of the middle sub-segment 21. At the ports of the sub-segments 21 on both sides of the transverse mounting bracket 2, a partial area of ​​the bottom of the sub-segments 21 on both sides overlaps with the sliding plate of the middle sub-segment 21. The plane covered by the overlapping area forms the sliding surface of the sub-segments 21 on both sides.

[0058] At the bottom of the break at the connecting end of the sub-segments 21 on both sides of the transverse mounting bracket 2, a first boss a215a is provided. The first boss a215a is generally n-shaped, and its bottom is fixedly connected to the bottom of the sub-segment 21. At both ends of the middle sub-segment 21, a second boss a216a is provided. The second boss a216a is generally n-shaped, and its bottom is fixedly connected to the bottom of the middle sub-segment 21. Below the second boss a216a, a channel not smaller than the first boss a215a is provided, and the height of this channel is the same as the height of the first boss. When the first boss a215a slides into the channel inside the second boss a216a, the top plane of the first boss a215a and the top plane of the inner channel of the second boss a216a are in contact with each other. Through holes are provided at designated positions on the top of the first boss a215a and the second boss a216a. When the sub-segments 21 on both sides and the middle sub-segment 21 are aligned with the predetermined position, the through holes on the first boss a215a and the second boss a216a overlap each other. The fastener 22 is a bolt, which passes through the through hole to fasten and fix the first boss a215a and the second boss a216a.

[0059] On the two side segments 21 of the horizontal mounting bracket 2, a first boss b215b is fixedly provided on the side wall. The first boss b215b is an L-shaped plate with the horizontal section facing upward and the vertical section of the L-shaped plate being fitted and fixedly connected to the side wall of the side segment 21 of the horizontal mounting bracket 2. On the middle segment 21, a first boss b215b is fixedly provided at the side wall of the end. The first boss b215b is an L-shaped plate with the horizontal section facing downward and the vertical section of the L-shaped plate being fitted and fixedly connected to the side wall of the side segment 21 of the horizontal mounting bracket 2. When the two segments 21 are combined, the first boss b215b is located below the first boss b215b, and the surfaces of the two bosses are fitted together. A through hole is provided at the joint of the first boss b215b and the first boss b215b. When the two segments 21 reach the predetermined installation position, the through holes on the first boss b215b and the first boss b215b overlap each other. The fastener 22 is a bolt, which passes through the through hole to fasten and fix the first boss b215b and the second boss b216b.

[0060] Among them, the first boss a215a and the first boss b215b are one embodiment of the first boss mentioned above; the second boss a216a and the second boss b216b are one embodiment of the second boss mentioned above.

[0061] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
