Thus, the pedestrian radiation detection device has a substantially gantry frame and is structurally stable.

For convenience, the pedestrian radiation detecting apparatus will be described below by taking the first pillar 1 as an example. It will be appreciated that the second upright 2 may have the same structure as the first upright, but is not limited thereto.

In an exemplary embodiment, the upper end of the lower cylinder 11 and the lower end of the upper cylinder 12 are connected by a first coupling means 5. To achieve a quick combination of the two. The first joining means 5 comprise: a lower combining part 51 installed at the upper end of the lower cylinder 11; and an upper coupling portion 52 installed at a lower end of the upper cylinder 12, the upper coupling portion 52 being configured to be detachably coupled with the lower coupling portion 51, thereby maintaining a stable connection between the upper cylinder 12 and the lower cylinder 11.

In an exemplary embodiment, as shown in fig. 1-5, the lower bonding portion 51 includes: a lower base 511 at the upper end of the lower cylinder 11; and a lower skirt 512 extending downward from the lower base 511 and fixed to the upper portion of the lower cylinder 11. For example, the lower skirt 512 may be secured to the upper end of the lower barrel 11 by threading, adhesive, or the like. The lower base 511 may have a general cover configuration and is mounted to the lower skirt 512 by attachment means such as screws 515. In an alternative embodiment, the lower skirt 512 may be integrally formed from the same material as the lower base 512.

On the other hand, the upper bonding portion 52 includes: an upper base 521 at the lower end of the upper cylinder 12; and a lower skirt 522 extending upwardly from the upper base 521 and secured to the lower portion of the upper cylinder 12. For example, the upper skirt 522 may be secured to the upper end of the lower barrel 12 by threading, adhesive, or the like. The upper base 521 may have a general cover configuration and is mounted to the upper skirt 522 by attachment members such as screws. In an alternative embodiment, the upper skirt 522 may be integrally formed from the same material as the upper base 521. The upper base 521 is provided with a first concave portion 523 which is inwardly concave, the lower base is provided with a first boss 513 which is outwardly convex, and the first boss 513 is combined into the first concave portion 523. In an alternative embodiment, the lower base portion is provided with an inwardly recessed first recess, and the upper base portion is provided with an outwardly protruding first boss, which is incorporated into the first recess.

In one embodiment, a plurality of guide holes 514 are formed on the lower base 511, a plurality of guide posts 524 are formed on the upper base, and the guide posts 524 are respectively coupled to the guide holes 514, thereby maintaining the stable coupling of the upper cylinder and the lower cylinder. Further, a positioning protrusion 516 protruding in the radial direction is provided on the first boss 513, and a positioning concave portion 525 recessing is provided on the first concave portion 523. When the lower cylinder 11 and the upper cylinder 12 are mounted, the positioning protrusions 516 and the positioning recesses 525 are aligned to mount the first bosses 513 into the first recesses 523. In this way, it is possible to prevent erroneous insertion in the case where the lower cylinder 11 and the upper cylinder 12 are not aligned.

In an exemplary embodiment, the layout of the guide holes and the guide posts arranged on the first upright post and the second upright post is designed asymmetrically, and the number of the guide holes and the guide posts on the first upright post and the second upright post is inconsistent, so that the upper barrel body and the lower barrel body can be effectively prevented from being assembled mistakenly.

In an exemplary embodiment, as shown in fig. 1-5, the first coupling device 5 further includes a first locking mechanism 53, and the first locking mechanism 53 is configured to maintain the lower coupling portion 51 and the upper coupling portion 52 in a coupled state. Thus, the upper cylinder 52 can be prevented from being detached from the lower cylinder 51.

In detail, the first locking mechanism 51 includes: a plurality of first fixing hooks 531 mounted on one of the lower skirt 512 and the upper skirt (e.g., the upper skirt); and a plurality of first movable hooks 532 installed on the other one of the lower and upper skirts (e.g., the lower skirt), the first movable hooks 532 being operatively coupled to the first fixed hooks 531 and hooking the first fixed hooks 531 to maintain the lower and upper coupling parts 51 and 52 in a coupled state.

In an exemplary embodiment, referring to fig. 5, each of the first movable hooks 532 includes: a base portion 5321 mounted on an outer surface of the other of the lower skirt portion 512 and the upper skirt portion 522 (e.g., the lower skirt portion), two ears 5322 extending in parallel outward being provided on both sides of the base portion 5321; a pivot 5323 mounted between the two ears 5322; and two support brackets 5324 pivotally mounted on the pivot 5321; and coupling shafts 5325 installed at first ends (upper ends in fig. 5) of the two support frames 5324, the coupling shafts 5325 being operatively coupled into the first fixing hooks 531 to couple or decouple the coupling shafts 5325 to or from the first fixing hooks 531 by driving second ends (lower ends in fig. 5) of the support frames 5324 opposite to the first ends.

in an exemplary embodiment, the coupling shaft 5325 is rotatably mounted at a first end of two of the support brackets 5324. In this way, the coupling shaft 5325 can be rollingly coupled into the first fixing hook 531 or rollingly decoupled from the first fixing hook 531, achieving smooth coupling or decoupling.

In an exemplary embodiment, each of the first movable hooks 532 further includes an operating portion 5326, the operating portion 5326 being pivotably mounted on the pivot 5323 and covering at least a portion of the support frame 5324, such that the support frame 5324 is driven to rotate about the pivot by pressing the operating portion 5324 to rotate about the pivot 5323, and the coupling shaft 5325 can be coupled to or decoupled from the first fixed hook 531.

In an exemplary embodiment, each of the first movable hooks 532 further includes a first return means, and the support bracket 5324 pivots about the pivot against the elastic force of the first return spring. Thus, after the support 5324 is pivoted while being pressed, the first support can be returned by the elastic force of the first return spring. Further, each of the first movable hooks 532 further includes a second return means, and the coupling shaft 5325 moves away from the pivot 5323 against the elastic force of the second return spring. In this way, the coupling shaft 5325 can be firmly held in the first fixing hook 531. Furthermore, through arranging the first resetting device and the second resetting device, certain flexibility of the upper cylinder body and the lower cylinder body at the combination part can be ensured. Therefore, in the process of assembling the upper cylinder and the lower cylinder, the upper cylinder and the lower cylinder and the ray detectors inside the upper cylinder and the lower cylinder are protected, and the damage of the upper cylinder and the lower cylinder and the ray detectors inside the upper cylinder and the lower cylinder due to a too rigid structure is avoided.

In an exemplary embodiment, the first moveable hook 532 further includes a first enclosure 5326 and a second enclosure 5327 adapted to cover the support bracket 5324, the first return spring, and the second return spring. The first enclosure 5326 and the second enclosure 5327 may be two separate pieces or may be a single piece integrally formed.
