[0002] X-ray inspection equipment is a specialized instrument that utilizes the penetrating properties of electromagnetic waves such as X-rays and gamma rays to perform non-destructive testing on the internal structure of objects. It identifies internal defects or structural features of materials by observing changes in projection intensity caused by the interaction of rays with matter. Since radiation is harmful to human health, X-ray inspection equipment is housed in a shell structure with an electrically operated door, which is only opened when loading or unloading the workpiece. Existing technology provides an X-ray inspection device where the electrically operated door is controlled by a button. However, this is inconvenient when both hands are needed to hold the workpiece for loading and unloading, affecting inspection efficiency. Furthermore, mechanical buttons have a limited lifespan and are easily damaged by frequent pressing, impacting the reliability of the X-ray inspection equipment. Utility Model Content

The detection element is configured to detect the body part. The drive mechanism is configured to drive the switch door to open the entrance / exit when the detection element detects the body part.

[0008] In one embodiment, the housing assembly further includes a support leg connected to the bottom of the housing, and the detection position is located below the housing assembly.

[0009] In one embodiment, the housing assembly further includes an indicator disposed at the detection position for indicating the detection position.

[0010] In one embodiment, the housing structure further includes a projection lamp assembly detachably connected to the housing, the projection lamp assembly being configured to project a light and shadow image toward the detection position to form the indicator.

[0011] In one embodiment, the projection lamp assembly includes a mounting bracket and a projection lamp, the mounting bracket being detachably connected to the housing, and the projection lamp being disposed on the mounting bracket and located directly above the detection position.

[0012] In one embodiment, one of the mounting bracket and the housing has an oblong hole and the other has a threaded hole. The length of the oblong hole extends along the height direction of the housing, and a fastener passes through the oblong hole and is screwed into the threaded hole.

[0013] In one embodiment, a mounting cavity is further formed within the housing, the mounting cavity and the working cavity are isolated from each other, and the mounting cavity is located below the working cavity. An opening communicating with the mounting cavity is formed at the bottom of the housing. The housing includes a front side plate and a frame surrounding the edge of the front side plate. The inlet and outlet are disposed on the front side plate. The bottom of the frame has a recessed clearance groove. The projection lamp assembly is disposed within the mounting cavity and located above the clearance groove, which is located above the detection position.

[0014] In one embodiment, the detection element is disposed within the clearance groove.

[0015] In one embodiment, the switch assembly includes two detection elements, which are respectively located on two opposing inner walls of the clearance groove.

[0016] Another objective of this invention is to provide a radiographic testing device with a cover structure featuring a switchable door. This structure solves the problems of existing push-button electric doors being inconvenient to use, affecting testing efficiency, and prone to damage from frequent pressing, thereby improving the operational reliability of the radiographic testing device.

[0017] To achieve this objective, the present invention employs the following technical solution in another aspect:

[0018] A radiation inspection device is provided, comprising a housing structure with a switchable door as described in any of the above embodiments, the radiation inspection device further comprising a detection component disposed within the working cavity of the housing structure.

[0019] The beneficial effects of this utility model are:

[0020] The present invention provides a housing structure with a switchable door, wherein the housing has an inlet and outlet communicating with the working chamber. The switchable door is movably connected to the housing to close or open the inlet and outlet.

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0031] like Figures 1 to 3As shown, this embodiment first provides a housing structure with a switchable door. The housing structure with a switchable door includes a housing assembly 1 and a switch assembly 2. The housing structure is applied to a radiation detection device. The housing assembly 1 includes a housing 11 and a switchable door 12. The housing 11 has a working cavity, and a detection assembly (not shown in the figure) for detecting the object to be detected is disposed in the working cavity. This embodiment does not limit the radiation type of the detection assembly.

[0032] The housing 11 has an entrance / exit communicating with the working chamber. A switch door 12 is movably connected to the housing 11 to close or open the entrance / exit. When the switch door 12 is open, the operator holds the object to be tested and enters or exits the working chamber through the entrance / exit. The housing assembly 1 has a detection position 10, which can accommodate a body part. The switch assembly 2 includes a drive mechanism 21 and a detection element 22. The drive mechanism 21 is used to drive the switch door 12 to move. The detection element 22 is communicatively connected to the drive mechanism 21 and is disposed on the housing assembly 1, located beside the detection position 10. The detection element 22 is configured to detect a body part, and the drive mechanism 21 is configured to drive the switch door 12 to open the entrance / exit when the detection element 22 detects a body part. When the operator places a body part on the detection position 10, the detection element 22 next to the detection position 10 can detect the body part. When the detection element 22 detects the body part, the drive mechanism 21 drives the opening and closing door 12 to open the entrance and exit, allowing the operator to enter and exit. This eliminates the need for the operator to press a button, avoiding the problems of limited lifespan and damage caused by frequent pressing of mechanical buttons. It also avoids the inconvenience of operating buttons when holding the object to be tested. The operator can quickly open the working chamber, improving detection efficiency. Moreover, the drive mechanism 21 only drives the opening and closing door 12 to open the entrance and exit when the operator places a body part on the detection position 10, avoiding misoperation or false detection and improving safety and reliability.

[0033] The principle of the communication connection between the detection element 22 and the drive mechanism 21 can be set with reference to the prior art. It should be noted that for some X-ray detection equipment, the drive mechanism 21 can not only drive the switch door 12 to open, but also drive it to close. When the operator needs to open the switch door 12, they place their body part in the detection position 10. Using the switch assembly 2, the detection element 22 can detect the body part, thereby driving the drive mechanism 21 to open the switch door 12. After the operator places the object to be detected into the housing 11, the drive mechanism 21 drives the switch door 12 to close, preventing others from entering the housing 11 or reducing the risk of X-ray leakage. When the operator needs to remove the object to be detected from the housing 11, the operator needs to place their body part in the detection position 10 again. The detection element 22 beside the detection position 10 detects the body part, and the drive mechanism 21 drives the switch door 12 to open the entrance / exit again. The specific structure and driving principle of the drive mechanism 21 can be set with reference to the prior art, which is not the focus of this application. For example, in one embodiment, as... Figure 2 As shown, the drive mechanism 21 includes a drive motor and a transmission belt. The transmission belt is fixedly connected to the door 12. The drive motor rotates, thereby driving the transmission belt to move, causing the door 12 to open. The transmission belt has a ring structure. When the drive mechanism 21 is activated, the transmission belt rotates in a ring, causing the door 12 to move back and forth in the horizontal direction, forming an opening or closing action.

[0034] In one embodiment, the housing assembly 1 further includes a support leg 13 connected to the bottom of the housing 11. A detection position 10 is disposed below the housing assembly 1, located between the bottom of the housing 11 and the ground, and is used to accommodate the operator's feet. This allows the operator to easily extend their feet while holding the object to be tested, and also requires less space than other body parts. In other embodiments, the detection position 10 can be set at a suitable height depending on the body part being tested.

[0035] The housing assembly 1 also includes an indicator, which is disposed at the detection position 10 and is used to indicate the detection position 10. The indicator can be a graphic indicator, a text indicator, or other means to indicate the detection position 10, making it easy for the operator to quickly identify the specific location of the detection position 10.

[0036] In one embodiment, the housing structure further includes a projection lamp assembly 3, which is detachably connected to the housing 11. The projection lamp assembly 3 is configured to project a light and shadow image toward the detection position 10 to form an indicator. The projection lamp assembly 3 projects images, text, or dynamic light and shadow onto the detection position 10 through optical principles, enabling the operator to quickly identify the specific location of the detection position 10. Using the projection lamp assembly 3 to form an indicator is relatively environmentally friendly and convenient, and the indicator text or graphics can be changed according to user needs.

[0037] For example, the projection light assembly 3 is positioned above the detection position 10. The projection light assembly 3 projects a footprint shape onto the ground of the detection position 10, which not only indicates the position of the detection position 10, but also prompts the operator to place their feet on the detection position 10, making it more intuitive.

[0038] The projection lamp assembly 3 includes a mounting bracket 31 and a projection lamp 32. The mounting bracket 31 is detachably connected to the housing 11, and the projection lamp 32 is mounted on the mounting bracket 31 and located directly above the detection position 10. This allows the projected indicator to be formed on the ground in the detection position 10 area, conforming to the operator's observation habits and enabling them to quickly see the text or graphics on the ground.

[0039] To adjust the installation height of the projection lamp assembly 3, one of the mounting bracket 31 and the housing 11 has an oblong hole 311, and the other has a threaded hole 113. The length of the oblong hole 311 extends along the height direction of the housing 11. Fasteners pass through the oblong hole 311 and are screwed into the threaded hole 113. In one embodiment, the fastener is a bolt. The housing 11 has multiple threaded holes 113 spaced apart along the height direction. By moving the mounting bracket 31 along the height direction and aligning the bolts with threaded holes 113 at different heights, the installation height of the projection lamp assembly 3 can be adjusted. Changing the installation height can accommodate different user needs. Raising the installation height of the projection lamp assembly 3 can change the size of the projected image, making it easier for the operator to identify.

[0040] The housing 11 also has a mounting cavity, which is isolated from the working cavity and located below the working cavity. An opening communicating with the mounting cavity is formed at the bottom of the housing 11. The working cavity serves as the detection space, and the mounting cavity and working cavity are isolated from each other to prevent radiation leakage through the opening. The housing 11 includes a front panel 111 and a frame 112 surrounding the edge of the front panel 111. An entrance / exit is located on the front panel 111. The bottom of the frame 112 has a recessed clearance groove 1121. The projection lamp assembly 3 is disposed within the mounting cavity and above the clearance groove 1121, which is located above the detection position 10. The recessed clearance groove 1121 formed by the structure of the frame 112 does not damage the structural integrity of the front panel 111, reducing the impact on the structural strength of the front panel 111. Furthermore, placing the projection lamp assembly 3 within the mounting cavity maintains a neat appearance and prevents external collisions with the projection lamp assembly 3. The clearance groove 1121 avoids the projection lamp assembly 3, so that the resulting projection is closer to the front side panel 111, making it easier for the operator to observe.

[0041] In one embodiment, the detection element 22 is disposed within the clearance groove 1121, which provides protection for the detection element 22, preventing it from being damaged by collisions with external objects, and is located close to the detection position 10. The detection element 22 employs an infrared sensor, which is a device capable of detecting infrared light and converting it into a measurable electrical signal. It has advantages such as non-contact operation and high sensitivity. When the operator places their foot on the detection position 10, the detection element 22 can quickly sense this and send an electrical signal to the drive mechanism 21.

[0042] To reduce the risk of false detection and missed detection, the switch assembly 2 includes two detection elements 22, which are located on two opposite inner walls of the clearance groove 1121. The two detection elements 22 detect the operator's feet at the same time. Moreover, the drive mechanism 21 will drive the door 12 to open and close only when both detection elements 22 detect body parts, thereby further improving safety.

[0043] This utility model embodiment further provides a radiation detection device, which includes the housing structure as described in any of the above embodiments. The device also includes a detection component disposed within the working chamber of the housing structure. When an operator places a body part on the detection position 10, the detection element 22 beside the detection position 10 can detect the body part. The drive mechanism 21 drives the opening and closing door 12 to open the entrance / exit when the detection element 22 detects the body part, allowing the operator to enter and exit without pressing a button. This avoids the problems of limited lifespan and frequent damage caused by mechanical buttons, and also avoids the inconvenience of operating buttons when holding the object to be detected. The operator can quickly open the working chamber, improving detection efficiency. Moreover, the drive mechanism 21 only drives the opening and closing door 12 to open the entrance / exit when the operator places a body part on the detection position 10, avoiding misoperation or false detection and improving the safety and reliability of the radiation detection device.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
