[0048] The conveying assembly 38 includes a third slide groove 381 symmetrically opened on both sides of the inner wall of the box body 1, and a fourth slide groove 382 is opened on the other two sides of the inner wall of the box body 1. A first connecting hole 383 is horizontally opened on the top of the fourth slide groove 382. A circulation pool 384 is arranged in the box body 1. Limit rods 3841 are symmetrically fixedly connected on both sides of the circulation pool 384. The limit rods 3841 are located in the third slide groove 381, and one end of the limit rod 3841 is fixedly connected to the fifth connecting shaft 217; a conveying pipe 385 is horizontally penetrated on both sides of the circulation pool 384, and the conveying pipe 385 is fixedly connected to the circulation pool 384. A plurality of baffles 386 are fixedly connected to the inner wall of the conveying pipe 385. The baffle 386 is hollow, and a blocking plate 387 and a fourth elastic member 388 are arranged in the baffle 386. One end of the fourth elastic member 388 is fixedly connected to the blocking plate 387, and the other end of the fourth elastic member 388 is fixedly connected to the inner wall of the baffle 386.

[0049] A baffle 386 extends out of one end of the blocking plate 387, and an annular groove 389 is horizontally opened on the conveying pipe 385. A limiting ring 3810 is arranged in the annular groove 389. One end of the limiting ring 3810 extends out of the annular groove 389 and is located in the fourth slide groove 382. A plurality of connecting plates 3811 are fixedly connected to the limiting ring 3810, and a second connecting hole 3812 is horizontally opened on the connecting plate 3811; a connecting rope 3813 is arranged in the second connecting hole 3812, and one end of the connecting rope 3813 is fixedly connected to the inner wall of the second connecting hole 3812, and the other end of the connecting rope 3813 passes through the inner wall of the annular groove 389 and is fixedly connected to the blocking plate 387; one end of the connecting plate 3811 is fixedly connected to the fifth elastic member 3814, and one end of the fifth elastic member 3814 is fixedly connected to the inner wall of the annular groove 389.

[0050] Embodiment 1: Figure 1-Figure 11As shown, in this embodiment, when it is necessary to detect the radioactive labeled compound, the top cover 11 is first flipped over. Since the length of the adjusting rod 27 remains unchanged, one end of the adjusting rod 27 is connected to the first connecting shaft 26 through a bearing, and the first connecting shaft 26 is fixedly connected to the connecting strip 21. When the connecting strip 21 is stationary, the second connecting shaft 28 drives one end of the adjusting rod 27 to move along the second slide groove 15. As the angle between the top cover 11 and the box body 1 becomes larger and larger, when the length of the adjusting rod 27 is not sufficient to continue to open the top cover 11, the end of the adjusting rod 27 connected to the first connecting shaft 26 through the bearing will pull the connecting strip 21 up along the first accommodating groove 13 through the first connecting shaft 26, thereby gradually opening the top cover 11 for easy operation by the detection personnel. In the process of the adjusting rod 27 driving the connecting strip 21 to rise along the first accommodating groove 13, since the adjusting rod 27 does not vertically pull the connecting strip 21 to rise along the first accommodating groove 13, there is an angle force, and the angle force is divided into vertical force and horizontal force. Because the slider 222 is fixedly connected to the connecting strip 21, and the slider 222 is located in the first slide groove 14, the connecting strip 21 is not affected by the horizontal force, avoiding the deflection of the connecting strip 21, and ensuring that the connecting strip 21 stably rises along the first accommodating groove 13 and the first slide groove 14.

[0051] It should be noted that the first elastic member 23 is initially in a compressed state, so that both ends of the first elastic member 23 push the limit strip 24, so that the limit strip 24 drives the first pulley 25 to fit the inner wall of the first receiving groove 13, and the auxiliary connecting strip 21 rises along the first receiving groove 13 and the first sliding groove 14.

[0052] During the process of the connecting strip 21 rising along the first accommodating groove 13, the second elastic member 214 and the third elastic member 215 located in the first adjusting block 210 and the second adjusting block 212 are first subjected to force and contracted. When the connecting strip 21 is flush with the fourth connecting shaft 211, the second elastic member 214 and the third elastic member 215 stop contracting. When the connecting strip 21 is higher than the fourth connecting shaft 211, the force on the second elastic member 214 and the third elastic member 215 is reduced, thereby stretching. When the top cover 11 is fully opened, the second elastic member 214 and the third elastic member 215 cooperate with the first adjusting block 210, the second adjusting block 212, the third connecting shaft 29 and the fourth connecting shaft 211 to support the connecting strip 21, so that the connecting strip 21 is stabilized in the first accommodating groove 13.

[0053] During the process of the connection bar 21 rising along the first receiving groove 13, the connection bar 21 drives the connection rod 216 to move upward along the third slide groove 381 through the third connection shaft 29, so that the fifth connection shaft 217 moves along the limit groove 219 and the third slide groove 381 at the same time, so that the fifth connection shaft 217 drives the rotating rod 218 to rotate, gradually retracting the second pulley 221, so that the box body 1 contacts the ground or platform, thereby reducing the probability of the equipment moving during the detection, and ensuring the safety of the detection personnel. During the process of the fifth connection shaft 217 rising along the third slide groove 381, since the fifth connection shaft 217 is fixedly connected to the limit rod 3841, the fifth connection shaft 217 drives the circulation pool 384 to rise along the inner wall of the box body 1 through the limit rod 3841, thereby shortening the distance between the circulation pool 384 and the scintillation crystal 37, thereby improving the detection effect of the equipment, so that the equipment can detect radioactive labeled compounds with lower concentrations, and improve the detection accuracy of the equipment.

[0054] It should be noted that: Figure 3 As shown, the flip top cover 11 facilitates the operator to use the touch screen 31 , so that the operator can issue instructions through the touch screen 31 .

[0055] It should be noted that: when the top cover 11 is turned over by 90°, the box body 1 is in contact with the ground or the platform, and the device can detect the compound at this time.

[0056] During the process of the circulation pool 384 rising along the inner wall of the box body 1, the limiting ring 3810 is squeezed by the inner wall of the fourth slide groove 382, ​​so that the fifth elastic member 3814 is compressed, thereby driving the limiting ring 3810 and the connecting plate 3811 to retract into the annular groove 389, so that the connecting plate 3811 pulls the connecting rope 3813, so that the connecting rope 3813 drives the blocking plate 387 to retract the baffle 386, thereby opening the delivery pipeline 385, so that the delivery pipeline 385 is connected with the first connecting hole 383, so as to facilitate the radioactive labeled compound to flow into or out of the device.

[0057] When the radioactive labeled compound is detected, the touch screen 31 controls the single chip microcomputer 32, so that the single chip microcomputer 32 starts the high voltage power supply 33, and the high voltage power supply 33 loads the electric field voltage between the dynodes of the photomultiplier tube, so that the photoelectrons are multiplied step by step in the electric field, and finally the pulse current is output at the anode to power the scintillation crystal 37, so that the radioactive signal in the radioactive labeled compound is converted into an electrical signal, and the electrical signal is transmitted to the amplification amplitude analysis unit 34, and the amplification amplitude analysis unit 34 amplifies, shapes, and analyzes the pulse amplitude of the electrical signal to output a pulse of a specific pulse width, and the frequency-voltage conversion unit 35 outputs the pulse of the specific pulse width as a voltage signal proportional to the frequency, and outputs it to the HPLC system for collection after buffering and amplification, and the single chip microcomputer 32 adjusts and collects the voltages of the high voltage power supply 33, the upper threshold, the lower threshold, etc. through the touch screen 31, counts the output pulses, collects the output voltage and displays them on the touch screen 31.

[0058] It should be noted that: when the top cover 11 is flipped 90°, when the amplification amplitude analysis unit 34 normally receives the radioactive signal in the radioactive labeled compound and converts it into an electrical signal, the current opening angle of the top cover 11 is maintained, so as to continuously detect whether the compound has a radioactive label.

[0059] When the top cover 11 is flipped 90°, and the amplification amplitude analysis unit 34 does not receive the radioactive signal in the radioactive labeled compound and convert it into an electrical signal, the opening angle of the top cover 11 can be increased, thereby shortening the distance between the circulation pool 384 and the scintillation crystal 37, thereby further determining whether the compound has a radioactive label and improving the detection accuracy.

[0060] It should be noted that: the greater the opening angle of the top cover 11, the closer the distance between the circulation pool 384 and the scintillation crystal 37, the higher the detection accuracy, and the closer the distance between the circulation pool 384 and the scintillation crystal 37, the more the baffle plate 387 retracts the baffle 386, so that the entrance of the delivery pipeline 385 is opened more, the compound flow rate is increased, and the detection time is shortened and the detection efficiency is improved under the condition of high detection accuracy. When the detection is completed, the top cover 11 is closed, so that the connecting strip 21, the circulation pool 384, the baffle 386, the limit ring 3810 and the second pulley 221 are reset, thereby sealing the box 1 to prevent contaminants from entering the box 1 when the equipment is not being tested, thereby affecting the detection accuracy. At the same time, through the second pulley 221, the equipment can be moved quickly and is convenient for the detection personnel to carry.

[0061] Embodiment 2: Fig.12 As shown, in this embodiment, a method for detecting a radioactive labeled compound is provided, and the steps are as follows:

[0062] S1: First, the device is moved to a designated location by the second pulley 221 in the retractable unit 2;

[0063] S2: Flip the top cover 11 so that the top cover 11 drives the connecting strip 21 to rise along the first receiving groove 13 through the adjusting rod 27;

[0064] S3: The adjusting rod 27 drives the third connecting shaft 29 to rise, thereby driving the connecting rod 216 to rise, so that the bottom of the device contacts the ground or the platform;

[0065] S4: The connecting rod 216 drives the fifth connecting shaft 217 to rise, so that the fifth connecting shaft 217 drives the flow cell 384 to rise by driving the limiting rod 3841;

[0066] S5: The circulation pool 384 rises and drives the limiting ring 3810 to rise along the fourth slide groove 382, ​​so that the limiting ring 3810 gradually retracts into the annular groove 389 horizontally opened on the conveying pipe 385;

[0067] S6: The limiting ring 3810 pushes the connecting plate 3811 to move along the annular groove 389 , thereby pulling the blocking plate 387 to retract the baffle plate 386 through the connecting rope 3813 ;

[0068] S7: After the blocking plate 387 is completely retracted into the baffle plate 386, the first connecting hole 383 is connected to the delivery pipeline 385, so that the radioactive labeled compound can enter the device for detection.

[0069] The rest of the structure is the same as that of the first embodiment.
