[0002] Chinese patent document CN217385852U discloses a radiation protection structure of a security inspection machine, including a frame, two fixed plates are fixed at both ends of the frame, and the side walls of the plurality of fixed plates are connected to two rotating rings through bearings for common rotation, a driving motor is fixed to the side wall of one of the fixed plates, the main shaft of the driving motor passes through the fixed plate and is fixed to the end of one of the rotating rings, the circumferential side walls of the two rotating rings are jointly sleeved with a conveyor belt, and the inner top of the frame is fixed with a detector body. In this device, by arranging two groups of sealing baffles that can move up and down inside the frame, the sealing baffles that abut against the inner wall of the frame and the upper end of the conveyor belt can be used to achieve sealing of the detector body, which can make the luggage detection effect better and effectively reduce the leakage of radiation when the luggage is put in and taken out. Combined with the protection of the lead curtain, the radiation protection structure of the security inspection machine can have a better protection effect.

[0003] The defects of the above security inspection device are: when the device is used in places with high passenger flow such as stations and airports, it is necessary to frequently open and close the sealing baffle to achieve radiation protection, and passengers need to wait for the sealing baffle to close and open, and this waiting time will cause passengers to be stranded; especially on peak passenger flow days such as holidays, there will be hundreds of passengers waiting for security inspection at a security inspection entrance, and the time waiting for the sealing baffle to move will further increase the time passengers wait for security inspection. In addition, the sealing baffle needs to be driven by an electric telescopic rod. Every time a passenger passes through the security inspection entrance, the electric telescopic rod needs to reciprocate. For example, in cities such as Beijing and Shanghai, the daily passenger throughput of the EMU station can reach more than 200,000. The high-frequency reciprocating operation of the electric telescopic rod is also prone to damage. Utility Model Content

Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.

[0022] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0023] Reference Figures 1 to 4As shown, a radiation-proof luggage security inspection device comprises a housing 1, a conveyor belt 2 is provided at the bottom of the housing 1, the housing 1 comprises an inlet end 11 and an outlet end 12, an X-ray searchlight is provided between the inlet end 11 and the outlet end 12, and at least two or more radiation-proof curtains 3 arranged at intervals are provided at the inlet end 11 and the outlet end 12, and a transition space is formed between two adjacent radiation-proof curtains 3 located at the inlet end 11 or the outlet end 12. The luggage is placed on the conveyor belt 2, and the luggage is transported to the housing 1 through the conveyor belt 2, and the luggage is inspected by the X-ray searchlight. When the luggage pushes away the radiation-proof curtain 3 on the outer side of the housing 1, the radiation-proof curtain 3 on the inner side of the housing 1 is in a closed state and plays a role in preventing radiation; then when the luggage moves to the transition space, the radiation-proof curtain 3 on the outer side of the housing 1 is automatically closed due to gravity; finally, the luggage pushes away the radiation-proof curtain 3 on the inner side of the housing 1, and the radiation-proof curtain 3 on the outer side of the housing 1 is in a closed state and plays a role in preventing radiation. Thus, the above multiple radiation protection curtains 3 are used to prevent radiation from spilling out and causing harm to the human body. When a person reaches into the radiation protection curtain 3 on the outer side of the housing 1 to take luggage, the radiation protection curtain 3 on the inner side of the housing 1 prevents radiation from spilling out and causing harm to the human body.

[0024] Reference Figure 2 As shown, in the present invention, the number of radiation-proof curtains 3 at the inlet end 11 and the outlet end 12 is two, namely, the first radiation-proof curtain 3a and the second radiation-proof curtain 3b. Security checks are required in places such as scenic spots, conferences, sports events, exhibitions, performance venues, airports, railway stations, subway stations, and bus stations. The specifications of the luggage carried by the inspected personnel in each place vary greatly. For example, in places such as railway stations or subway stations, large luggage such as suitcases are often carried, while in places such as exhibitions and performances, small luggage such as school bags and handbags are carried. In order to meet the security inspection requirements of different places, the width of the transition space is adjusted by the cooperation of the positioning member 4 and the adjusting member 5 so that it can adapt to luggage of different specifications, thereby avoiding the transition space being too small, so that when the luggage is located in the transition space, there is a situation where the first radiation-proof curtain 3a and the second radiation-proof curtain 3b are lifted up at the same time.

[0025] Reference Figure 2 As shown, specifically, the positioning member 4 is fixed to the shell 1, and the positioning member 4 is provided with a slide groove for the adjusting member 5 to slide. The positioning member 4 and the adjusting member 5 are slidably connected through the drawer slide rail, and also include a screw 6. The screw 6 passes through the shell 1 and the positioning member 4 and then supports the drawer slide rail. The screw 6 supports one of the joints of the drawer slide rail to limit the sliding between the slide rails, thereby limiting the sliding between the positioning member 4 and the adjusting member 5, thereby preventing the luggage from pushing the first radiation protection curtain 3a while driving the movement of the adjusting member 5.

[0026] Reference Figure 2As shown, the positioning member 4 and the adjusting member 5 are both plate-shaped structures, and the two are connected by drawer slide rails to ensure smooth sliding. The positioning member 4 can be fixed to the shell 1 by bolt locking, welding, etc.

[0027] Reference Figure 3 As shown, the lower ends of the first radiation protection curtain 3a and the second radiation protection curtain 3b are divided into a plurality of curtain pieces 31 by cutting with scissors, the seams of the curtain pieces 31 of adjacent first radiation protection curtains 3a constitute a first seam 3a1, and the seams of the curtain pieces 31 of adjacent second radiation protection curtains 3b constitute a second seam 3b1, and the first seam 3a1 and the second seam 3b1 are arranged alternately, thereby avoiding the radiation spillover at the seams due to insufficient tightness between the curtain pieces 31 and damage to the human body.

[0028] In order to facilitate the repair of the first radiation-proof curtain 3a and the second radiation-proof curtain 3b after damage, the first radiation-proof curtain 3a is detachably connected to the adjusting member 5 by Velcro, and the second radiation-proof curtain 3b is detachably connected to the positioning member 4 by Velcro. Specifically, one end of the Velcro can be glued to the bottom surface of the adjusting member 5 or the positioning member 4, and the other end of the Velcro can be sewn to the top of the first radiation-proof curtain 3a or the second radiation-proof curtain 3b by needle and thread.

[0029] Reference Figure 4 As shown, the lower end of the radiation-proof curtain 3 is divided into a plurality of curtain pieces 31, one of the two adjacent curtain pieces 31 is provided with a plurality of magnets 32 arranged at intervals, and the other curtain piece 31 is provided with an adsorbed part 33 for adsorption by the magnet 32. The magnet 32 ​​is used as an adsorbing part, and the adsorbed part 33 can be selected from magnets 32 with opposite magnetic poles or metals that can be adsorbed by the magnet 32. The cooperation between the magnet 32 ​​and the adsorbed part 33 ensures that the curtain pieces 31 can be closely matched, thereby preventing the splicing between the curtain pieces 31 from being not tightly enough, resulting in radiation spilling out of the seams and causing damage to the human body.

[0030] Reference Figure 4 As shown, a counterweight 34 is provided at the lower end of the curtain piece 31. The counterweight 34 allows the curtain piece 31 to be quickly reset after the luggage pushes the curtain piece 31 away, and the counterweight 34 can be fixed to the curtain piece 31 by gluing or sewing.

[0031] In order to ensure the radiation protection effect of the radiation protection curtain 3, preferably, the radiation protection curtain 3 is made of radiation protection lead rubber.
