[0030] The portable device 3 includes a fixing block 301, a mounting hole 302, a threaded rod 303, a universal wheel 304, a connecting block 305, a telescopic rod 306, a handle 307, an anti-slip cover 308, a shrink hole 309, a first spring 310, a limiting plate 311, a limiting block 312 and an adjustment hole 313.

A connecting block 305 is connected, a telescopic rod 306 is fixedly connected above the connecting block 305, a handle 307 is slidably connected to the outer wall surface of the telescopic rod 306, a non-slip cover 308 is fixedly connected to the surface of the handle 307, a contraction hole 309 is opened on the inner wall of the telescopic rod 306, one end of the inner wall of the contraction hole 309 is fixedly connected to a first spring 310, one end of the first spring 310 is fixedly connected to a limiting plate 311, one end of the limiting plate 311 is fixedly connected to a limiting block 312, an adjustment hole 313 is opened on the inner wall surface of the handle 307, and the portable device 306 is connected to the inner wall of the telescopic rod 306. The threaded rod 303 is closely connected with the mounting hole 302 so that the universal wheel 304 is closely connected to the surface of the fixing block 301. Then, hold the handle 307. The anti-slip sleeve 308 can increase the friction between the hand and the handle 307 to prevent the hand from slipping. If the height of the handle 307 needs to be adjusted, the handle 307 can be pulled outward. At this time, the limit block 312 compresses the first spring 310 to make the limit block 312 disengage from the current adjustment hole 313. Then, slide the handle 307 to a suitable position. Under the action of the first spring 310, the limit block 312 The corresponding adjustment hole 313 is inserted to fix the height of the handle 307 to meet the needs of different operators. The contraction hole 309, the first spring 310, the limit plate 311 and the limit block 312 inside the telescopic rod 306 cooperate to achieve flexible adjustment and fixation of the height of the handle 307, which provides convenience for the operator and improves the comfort and adaptability of the device. Its portability and versatility reduce the dependence on large fixed equipment, reduce the cost of equipment procurement and maintenance, and achieve rapid detection of X-ray sources in different working environments.

[0031] Furthermore, multiple groups of universal wheels 304 are arranged at the bottom of the box body 1, and are symmetrically arranged on the surface of each group of fixed blocks 301 with respect to the transverse central axis of the box body 1. Through the arrangement of the universal wheels 304, the stability and stability of the equipment during movement are enhanced, and the possibility of tilting or bumping during movement is reduced. The evenly distributed supporting force enables the equipment to move smoothly even when carrying heavy objects, thereby improving the load capacity of the equipment.

[0032] Furthermore, the outer wall size of the telescopic rod 306 is consistent with the size of the groove on the inner wall of the handle 307. The limit plate 311 cooperates with the limit block 312 through the first spring 310 to form a telescopic structure. Through the setting of the telescopic rod 306 and the first spring 310, the smoothness of the handle 307 when sliding on the telescopic rod 306 is guaranteed, the jamming and shaking are reduced, and the smoothness of operation is improved. The first spring 310 enables the limit block 312 to be flexibly extended and retracted, and reliable engagement and unlocking are achieved, ensuring the convenience and stability of the height adjustment of the handle 307.

[0033] Furthermore, the outer wall size of the limit block 312 is consistent with the inner wall size of the adjustment hole 313. There are multiple groups of adjustment holes 313 on the inner wall surface of the handle 307, and each group of adjustment holes 313 is evenly spaced. Through the setting of the adjustment holes 313, it can be ensured that the limit block 312 can be accurately inserted into the adjustment holes 313 to provide a stable fixing effect. At the same time, multiple groups of evenly spaced adjustment holes 313 provide the handle 307 with multiple selectable heights to meet the comfort needs of different operators and improve the versatility and humanization of the device.

[0034] Furthermore, the shock absorbing device 8 includes a sleeve 801, a positioning groove 802, a second spring 803, a slot 804, a damping block 805, a positioning block 806, a movable rod 807 and a supporting foot 808. The bottom surface of the built-in plate 6 is fixedly connected with the sleeve 801, the interior of the sleeve 801 is provided with a positioning groove 802, the top surface of the positioning groove 802 is fixedly connected with the second spring 803, both sides of the positioning groove 802 are provided with slots 804, the inner wall surface of the slot 804 is slidably connected with the damping block 805, one end of the damping block 805 is fixedly connected with the positioning block 806, the bottom surface of the positioning block 806 is fixedly connected with the movable rod 807, and the bottom surface of the movable rod 807 is fixedly connected with the supporting foot 808. Through the setting of the shock absorbing device 8, when the portable X-ray source testing device is vibrated, the built-in plate 6 will have a tendency to move up and down. 6 drives the sleeve 801 to move, so that the movable rod 807 slides in the positioning groove 802 of the sleeve 801. When the movable rod 807 moves upward, the second spring 803 is compressed, and the second spring 803 generates a reverse elastic force to slow down the upward movement. At the same time, the damping blocks 805 on both sides of the positioning block 806 slide in the slot 804. The friction between the damping block 805 and the inner wall of the slot 804 further consumes the vibration energy and plays a role in damping and shock absorption. When the movable rod 807 moves downward, the second spring 803 stretches and also generates a reverse pulling force to slow down the downward movement. The damping block 805 continues to slide in the slot 804 and continues to play a damping role. Through the elastic buffering of the second spring 803 and the damping effect of the damping block 805, the influence of vibration on the built-in plate 6 and related components is effectively reduced, thereby ensuring the stability and reliability of the device.

[0035] Furthermore, the positioning block 806 slides up and down inside the positioning slot 802 through the second spring 803, and the inner wall size of the slot 804 matches the outer wall size of the damping block 805. The setting of the positioning slot 802, the second spring 803, the slot 804 and the damping block 805 ensures the stability and directionality of the movement of the positioning block 806, so that it can only move up and down along the axis of the positioning slot 802, avoiding deviation and shaking, thereby more effectively transmitting and buffering vibration energy. The slot 804 and the damping block 805 with matching sizes can provide a stable damping effect, fully consume vibration energy, and reduce the transmission of vibration.

[0036] Furthermore, multiple groups of sleeves 801 are arranged on the bottom surface of the built-in plate 6, and are respectively arranged at the four corners of the built-in plate 6 and in the middle of the built-in plate 6. Through the arrangement of the sleeves 801, uniform and comprehensive support and shock absorption are provided at the key positions of the built-in plate 6. No matter which direction the vibration comes from, it can be effectively buffered and absorbed, thereby improving the overall stability of the built-in plate 6, so that in a vibration environment, the components on the built-in plate 6 can maintain a relatively stable working state, reducing the risk of displacement and damage caused by vibration.

[0037] Furthermore, the protective device 9 includes a housing 901, a motor box 902, a motor 903, a rotating shaft 904, a fan blade 905, a protective plate 906, a ventilation slot 907, a dust plate 908, a threaded hole 909, a bolt 910 and a nut 911. The housing 901 is fixedly connected to the surface of one side of the box body 1, the motor box 902 is fixedly connected to the inner wall surface of the housing 901, the motor 903 is fixedly connected to one end of the inner wall of the motor box 902, and the rotating shaft 904 is fixedly connected to the surface of one end of the motor 903. The rotating shaft 904 has a fan blade 905 fixedly connected to the outer wall surface of the rotating shaft 904, and a protective plate 906 is rotatably connected to the end surface of the rotating shaft 904. A ventilation slot 907 is provided on one side surface of the box body 1, and a dustproof plate 908 is connected to the inner wall surface of the box body 1. The surface of the dustproof plate 908 has a threaded hole 909, and a bolt 910 is threadedly connected to the inner wall surface of the threaded hole 909. A nut 911 is threadedly connected to the outer wall surface of the bolt 910. By setting the protective device 9, at high temperature Under such circumstances, excessively high temperature will affect the performance of the equipment. Therefore, when it is necessary to ventilate and dissipate heat for the box body 1, the motor 903 in the motor box 902 is started, and the motor 903 drives the rotating shaft 904 to rotate, thereby rotating the fan blades 905 on the outer wall surface of the rotating shaft 904. The rotation of the fan blades 905 generates airflow, and the airflow enters the interior of the box body 1 through the ventilation slots 907, which can quickly and effectively ventilate and dissipate heat for the interior of the box body 1, prevent the internal equipment from being damaged due to overheating, and extend the service life of the equipment. On the one hand, the protective plate 906 can prevent external objects from directly contacting the rotating fan blades 905, thereby playing a role in safety protection. On the other hand, it also helps to guide the direction of the airflow. During the ventilation process, the dustproof plate 908 on the inner wall surface of the box body 1 can prevent dust and other impurities from entering the box body 1. The dustproof plate 908 is fixed to the inner wall of the box body 1 by bolts 910 passing through the threaded holes 909 and cooperating with nuts 911. This connection method is convenient for disassembly and cleaning of the dustproof plate 908 to ensure its dustproof effect.

[0038] Furthermore, the rotating shaft 904 cooperates with the fan blades 905 through the second motor 903 to form a rotating structure. The fan blades 905 are evenly spaced on the outer wall surface of the rotating shaft 904 in multiple groups. Through the setting of the fan blades 905, airflow can be generated stably and efficiently. The rotation of the fan blades 905 can promote the rapid flow of air, thereby sucking in the cold air outside the box 1 and expelling the hot air inside the box 1, which greatly improves the heat dissipation efficiency, ensures that the equipment inside the box 1 operates at a suitable temperature, and extends the service life of the equipment. The fan blades 905 are evenly spaced on the outer wall surface of the rotating shaft 904 in multiple groups, which makes the generated airflow more uniform, and can perform more balanced heat dissipation on various parts inside the box 1, avoiding the occurrence of local overheating, and further protecting the performance and stability of the equipment.

[0039] Furthermore, the position of the dustproof plate 908 corresponds to the position of the ventilation slot 907, and multiple groups of bolts 910 are arranged on the surface of the dustproof plate 908. Through the arrangement of the dustproof plate 908 and the bolts 910, dust can be directly prevented at the point where the air enters the ventilation slot 907, ensuring that the air entering the box 1 is as clean as possible, and effectively preventing dust and other impurities from damaging the equipment in the box 1. The bolts 910 make the installation of the dustproof plate 908 more firm and stable. During the operation of the equipment, it will not loosen or fall off due to the impact of airflow or other external factors, thereby ensuring the durability and reliability of the dustproof effect. At the same time, the arrangement of the bolts 910 also facilitates the disassembly and installation of the dustproof plate 908, which is convenient for cleaning or replacement when necessary, and is more convenient for maintenance.

[0040] Working principle: First, the close connection between the threaded rod 303 and the mounting hole 302 makes the universal wheel 304 tightly connected to the surface of the fixed block 301. Secondly, hold the handle 307. The anti-slip sleeve 308 can increase the friction between the hand and the handle 307 to prevent the hand from slipping. If the height of the handle 307 needs to be adjusted, the handle 307 can be pulled outward. At this time, the limit block 312 compresses the first spring 310, so that the limit block 312 is disengaged from the current adjustment hole 313, and then the handle 307 is slid to a suitable position. Under the action of the first spring 310, the limit block 312 is stuck in the corresponding adjustment hole 313, thereby fixing the height of the handle 307 to meet the needs of different operators. The contraction hole 309 inside the rod 306, the first spring 310, the limit plate 311 and the limit block 312 cooperate to realize the flexible adjustment and fixation of the height of the handle 307, which provides convenience for the operator and improves the comfort and adaptability of the device. Its portability and versatility reduce the dependence on large fixed equipment, reduce the cost of equipment procurement and maintenance, and realize rapid detection of X-ray sources in different working environments. At the same time, the operator can also easily carry the box 1 to the designated position through the side handle 2. During the test, the X-ray source emits rays, the detection head 4 receives the ray signal and converts it into an electrical signal and transmits it to the electronic component 7 inside the box 1 for processing.The touch screen 5 provides an intuitive operation interface, through which the user can set test parameters, view test results, etc. When the portable X-ray source test device is vibrated, the built-in plate 6 will tend to move up and down, and the built-in plate 6 drives the sleeve 801 to move, so that the movable rod 807 slides in the positioning groove 802 of the sleeve 801. When the movable rod 807 moves upward, the second spring 803 is compressed, and the second spring 803 generates a reverse elastic force to slow down the upward movement. At the same time, the damping blocks 805 on both sides of the positioning block 806 are in the card slot 804. The friction between the damping block 805 and the inner wall of the card slot 804 further consumes the vibration energy and plays a role in damping and shock absorption. When the movable rod 807 moves downward, the second spring 803 stretches and also generates a reverse pulling force to slow down the downward movement. The damping block 805 continues to slide in the card slot 804 and continues to play a damping role. Through the elastic buffering of the second spring 803 and the damping effect of the damping block 805, the impact of vibration on the built-in plate 6 and related components is effectively reduced, ensuring the stability and reliability of the device. Under high temperature conditions, Too high a temperature will affect the performance of the equipment. Therefore, when the box 1 needs to be ventilated and cooled, the motor 903 in the motor box 902 is started. The motor 903 drives the rotating shaft 904 to rotate, thereby rotating the fan blades 905 on the outer wall surface of the rotating shaft 904. The rotation of the fan blades 905 generates airflow, and the airflow enters the box 1 through the ventilation slots 907. It can quickly and effectively ventilate and cool the inside of the box 1, prevent the internal equipment from being damaged due to overheating, and extend the service life of the equipment. The protective plate 906 can prevent external objects from directly contacting the rotating The fan blades 905 not only play a role in safety protection, but also help to guide the direction of airflow. During ventilation, the dustproof plate 908 on the inner wall surface of the box body 1 can prevent dust and other impurities from entering the box body 1. The dustproof plate 908 is fixed to the inner wall of the box body 1 by bolts 910 passing through threaded holes 909 and in cooperation with nuts 911. This connection method facilitates the disassembly and cleaning of the dustproof plate 908 to ensure its dustproof effect. The model of the motor 903 is YE2-132S-4, thus completing the use of a portable X-ray source testing device.
