The X-ray source and the control box can be assembled and used to improve convenience.

[0003] However, in the prior art, the detachable structure will deteriorate the overall mechanical stability of the control box, and the mounting base of the radiation source will become loose after repeated use, which will cause the radiation source to produce tiny vibrations during operation. On the one hand, this vibration affects the accuracy of radiation emission, and on the other hand, it will accelerate the wear of other components inside the equipment and shorten the service life of the equipment. This mechanical stability problem leads to reduced repeatability and reliability of the detection results. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a ray source control box with a detachable source head, comprising a control box body and a ray source body, both sides of the control box body are fixedly connected with fixed blocks, and the side wall of the ray source body is installed with four limiting mechanisms;

[0006] The limiting mechanism includes a fixing plate, a mounting block is fixedly connected to one side of the fixing plate, an extrusion groove is provided in the center of the mounting block, and push rods are slidably connected to both sides of the mounting block, a mounting hole is provided at one end of the mounting block, a tension spring is installed inside the mounting hole, a support frame is fixedly connected to the side wall of the mounting block, a swing rod is rotatably connected to the inner side of the support frame, one end of the swing rod is fixedly connected to a clamping joint, both ends of the tension spring are clamped with the swing rod, an extrusion block is slidably connected to the inner side of the extrusion groove, the extrusion block abuts against two push rods respectively, and one end of the swing rod is fixedly connected to the limiting rod.

[0007] Preferably, one end of the push rod abuts against the limit rod, and one side of the mounting block is fixedly connected to two guide rods.

[0009] Preferably, one end of the threaded rod passes through the support plate, and the threaded rod is rotatably connected to the side wall of the extrusion block.

[0010] Preferably, an annular groove is provided on the outer surface of one end of the fixing block, and two guide holes are provided on one side of the fixing block.

[0011] Preferably, two plug-in slots are provided on one side of the ray source body, and a movable slot is provided on one side of the plug-in slots.

[0012] Preferably, a positioning rod is slidably connected to the inner side of the movable groove, and a limiting plate is fixedly connected to the outer surface of the positioning rod.

[0013] Preferably, a spring is provided inside the movable groove, and the spring is sleeved on the outer surface of the positioning rod.

[0016] Compared with the prior art, the advantages and positive effects of the utility model are:

[0017] 1. In the utility model, firstly, the anti-slip texture on the surface of the plug-in block and the resilience of the spring ensure the tightness of the plug-in and convenient separation; secondly, the guide hole is precisely aligned with the guide rod, and the threaded rod drives the extrusion block to provide an inclined force, pushes the limit rod and drives the swing rod to rotate, thereby realizing automatic resetting and stable connection; in addition, the card joint slides into the annular groove to ensure the stable positioning of the fixed block; the overall design enhances the flexibility of the device, adapts to a variety of operating scenarios, and effectively avoids loosening caused by vibration or external force, thereby ensuring safety and reliability in high-frequency operating environments.

[0018] 2. In the utility model, in the process of connecting the control box body and the radiation source body, the plug-in block not only meets the plug-in requirement with the spring, but also realizes the positioning function by pulling the positioning rod. When the positioning rod slides in the movable groove, it drives the limit plate to move and compresses the spring, thereby providing support for the stable insertion of the plug-in block. After the plug-in block is fully in place, the positioning rod is released, so that the rebound force of the spring pushes the limit plate to restore its initial position, and the positioning rod is inserted into the positioning hole, thereby realizing precise positioning and preliminary stable connection. In the separation operation, the extrusion block and the push rod are separated by external force, so that the tension spring is pulled close to the bottom end of the swing rod, and the card joint gradually breaks away from the limiting effect of the annular groove, completing the smooth separation of the control box body and the radiation source body. This design ensures the convenience and stability of connection and separation, and provides reliable support for the equipment in scenarios with high-frequency operation and high safety requirements.

[0025] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0027] Embodiment 1: Figure 1 - Figure 3 As shown, the utility model provides a detachable radiation source control box, comprising a control box body 1 and a radiation source body 2, both sides of the control box body 1 are fixedly connected with fixing blocks 3, and the side wall of the radiation source body 2 is installed with four limiting mechanisms 4;

[0028] The limiting mechanism 4 includes a fixed plate 41, a mounting block 44 is fixedly connected to one side of the fixed plate 41, an extrusion groove 43 is provided in the center of the mounting block 44, and push rods 46 are slidably connected to both sides of the mounting block 44, a mounting hole 48 is provided at one end of the mounting block 44, a tension spring 47 is installed inside the mounting hole 48, a support frame 421 is fixedly connected to the side wall of the mounting block 44, a swing rod 42 is rotatably connected to the inner side of the support frame 421, a clamping joint 423 is fixedly connected to one end of the swing rod 42, both ends of the tension spring 47 are clamped with the swing rod 42, an extrusion block 451 is slidably connected to the inner side of the extrusion groove 43, the extrusion block 451 is respectively abutted against two push rods 46, one end of the swing rod 42 is fixedly connected to the limiting rod 422, one end of the push rod 46 abuts against the limiting rod 422, and two guide rods 441 are fixedly connected to one side of the mounting block 44.

[0029] The following is a detailed description of the specific configuration and function of this embodiment. First, in terms of the connection between the plug-in block 11 and the spring 23, the surface of the plug-in block 11 may be provided with certain textures or anti-slip grooves to increase the friction between it and the spring 23, thereby ensuring the stability of the plug-in. During use, the spring 23 provides a certain resilience to ensure tightness after plugging, and can be quickly disengaged during separation, thereby improving the convenience of assembly and disassembly.

[0030] During the connection and positioning process, the fixing blocks 3 on both sides of the control box body 1 gradually approach the mounting blocks 44. At this time, while the guide holes 32 are plugged into the guide rods 441, the two components are also ensured to be smoothly aligned through the precise position of the guide rods 441. Subsequently, the extrusion block 451 is driven to move by the rotation of the threaded rod 45. When the trapezoidal extrusion block 451 slides inside the extrusion groove 43, it provides a stable inclined force, gradually pushing the movement of the push rod 46.

[0031] The push rod 46 moves away from the outside under the action of the extrusion block 451, and the external thrust of the push rod 46 is transmitted to the limit rod 422, prompting the swing rod 42 to rotate around the support frame 421. During the rotation process, the two swing rods 42 gradually pull the tension spring 47 inside the mounting hole 48. The tension spring 47 provides a pullback force when stretched to ensure that it can automatically reset after rotating into place. In addition, the clamping joint 423 slides into the inner side of the annular groove 31 under the pushing action to complete the clamping positioning of the fixing block 3. Through this multiple positioning and clamping, the stability and firmness of the control box body 1 and the radiation source body 2 after connection are ensured.

[0032] This design not only facilitates the combination and separation of the control box body 1 and the radiation source body 2, but also enhances the flexibility of use and supports a variety of operating scenarios. At the same time, during the transfer process, the synergistic effect of the limit mechanism 4 and the fixing block 3 makes the entire device more stable, effectively avoiding loosening caused by vibration or external force, thereby preventing the control box body 1 from colliding with the radiation source body 2. This structural design improves the safety of the equipment, ensures the convenience and reliability of operation, and is suitable for environments with frequent operations and high safety requirements.

[0033] Embodiment 2: Figure 2 , Figure 4 and Figure 5 As shown, a support plate 411 is fixedly connected to one side of the fixed plate 41, and a threaded rod 45 is threadedly connected to the middle of the support plate 411. One end of the threaded rod 45 passes through the support plate 411, and the threaded rod 45 is rotatably connected to the side wall of the extrusion block 451. An annular groove 31 is provided on the outer surface of one end of the fixed block 3, and two guide holes 32 are provided on one side of the fixed block 3. Two plug-in slots 24 are provided on one side of the ray source body 2, and a movable slot 25 is provided on one side of the plug-in slot 24. A positioning rod 21 is slidably connected to the inner side of the movable slot 25, and a limiting plate 22 is fixedly connected to the outer surface of the positioning rod 21. A spring 23 is arranged inside the movable slot 25, and the spring 23 is sleeved on the outer surface of the positioning rod 21. Both ends of the positioning rod 21 pass through the movable slot 25, and the top diameter of the positioning rod 21 is larger than the diameter of the circular hole at the top of the movable slot 25. A plug-in block 11 is fixedly connected to the top and bottom of one side of the control box body 1 . A positioning hole 12 is opened on one side of the plug-in block 11 . The positioning hole 12 is plugged into the bottom end of the positioning rod 21 .

[0034] The effect achieved by the entire embodiment is that, in the process of connecting the control box body 1 and the radiation source body 2, the design of the plug-in block 11 not only meets the plug-in requirements with the spring 23, but also can realize the positioning function by pulling the positioning rod 21 first. The positioning rod 21 will slide in the movable groove 25 during the pulling process, and at the same time drive the limit plate 22 to move together, so that the limit plate 22 squeezes the spring 23 outside the positioning rod 21, thereby compressing the spring 23. When the plug-in block 11 is fully inserted into the spring 23 and stably in place, the positioning rod 21 can be released. At this time, the reset elastic force of the spring 23 will push the limit plate 22 back to the initial position, and the limit plate 22 will then drive the positioning rod 21 to insert forward into the positioning hole 12, thereby completing the accurate positioning of the plug-in block 11. In this way, the control box body 1 and the radiation source body 2 are initially combined together, and a stable initial connection is achieved.

[0035] When the control box body 1 and the radiation source body 2 need to be separated, firstly, the squeezing block 451 and the two push rods 46 are moved away from each other by external force. At this time, the elastic force of the tension spring 47 comes into play, pulling the two swinging rods 42 closer, so that their bottom ends gradually come together. In this process, the clamping joint 423 will also gradually withdraw from the position of the annular groove 31 under the action of the tension, releasing the limiting effect on it. Through this separation operation, the clamping joint 423 is freed from the restriction of the annular groove 31, so that the control box body 1 and the radiation source body 2 can be separated smoothly.

[0036] The method of use and working principle of the device: When the control box body 1 and the radiation source body 2 are connected, the plug-in block 11 can not only be plugged with the spring 23, but also the positioning rod 21 can be pulled first to slide in the movable groove 25, and the limiting plate 22 can be driven to move together. In this process, the limiting plate 22 squeezes the spring 23 on the outer surface of the positioning rod 21 to compress the spring 23. After the plug-in block 11 is inserted into the spring 23, the positioning rod 21 is released, and the elasticity of the spring 23 pushes the limiting plate 22 to reset. The limiting plate 22 drives the positioning rod 21 to move, so that the positioning rod 21 is inserted into the positioning hole 12, and the positioning of the plug-in block 11 is completed, thereby realizing the preliminary combination of the control box body 1 and the radiation source body 2.

[0037] The fixed blocks 3 on both sides of the control box body 1 gradually approach the mounting block 44, at which time the guide hole 32 is plugged into the guide rod 441, and then the threaded rod 45 is screwed to drive the extrusion block 451 to move. When the extrusion block 451 of the trapezoidal structure slides inside the extrusion groove 43, it will push the push rod 46, so that the two push rods 46 move simultaneously and away from each other, and the push rod 46 applies a force to the limit rod 422, prompting the swing rod 42 to start rotating, and the limit rod 422 rotates around the support frame 421. During the rotation process, the two swing rods 42 pull the tension spring 47 in the mounting hole 48, and drive the clamping joint 423 to clamp into the inner side of the annular groove 31, completing the positioning of the fixed block 3. This structure is convenient for the combined use of the control box body 1 and the radiation source body 2, which is convenient for transfer, and is also conducive to split use, which improves the convenience of use. In addition, the limit mechanism 4 and the fixed block 3 are positioned in coordination, which can enhance the firmness after assembly, avoid looseness during the transfer process, and prevent the control box body 1 and the radiation source body 2 from colliding with each other.

[0038] When performing the separation operation, the squeezing block 451 is moved away from the two push rods 46 . At this time, the elasticity of the tension spring 47 pulls the swing rod 42 , so that the bottom ends of the two swing rods 42 are close to each other, so that the clamping joint 423 no longer limits the annular groove 31 .

[0039] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
