Description

Technical Field

[0001] The utility model relates to the technical field of protective lead covers, in particular to a protective lead cover for an X-ray security inspection machine. Background Art

[0002] X-ray security inspection machines are electronic devices that use X-ray scanning and imaging technology to perform security inspections on luggage. They use conveyor belts to send the inspected luggage into the X-ray inspection channel to complete the inspection. They are mainly installed in subways, airports, museums, government agencies and other places that require security inspections. The safety of items is judged based on scanning images. Since X-rays are harmful to the human body, security inspection machines are generally used with protective lead covers to block the hazards of X-rays.

[0003] When going through security check, personnel need to place their carry-on luggage such as backpacks on the conveyor belt surface of the security check machine. The conveyor belt drives the luggage to be transported, passing through the protective lead cover until it enters the security check machine, and the luggage is scanned by X-ray. When the luggage is inspected, the bottom of the lead cover and multiple pieces of luggage frequently rub against each other, which is prone to wear. Since the lead cover can only be replaced as a whole, and the degree of wear of the lead cover is different, the overall replacement transaction is a waste of resources. Therefore, a protective lead cover for an X-ray security check machine is proposed to address the above problems. Utility Model Content

[0004] The utility model aims to provide a protective lead cover for an X-ray security inspection machine, so as to solve the problem that the lead cover cannot be replaced individually according to the degree of wear.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A protective lead cover for an X-ray security inspection machine comprises a security inspection machine body, a conveyor belt and a base arranged in sequence from top to bottom, a conveyor belt is provided at the bottom of the security inspection machine body, a base is provided at the bottom of the conveyor belt, a fixed frame is fixedly connected to one side of the security inspection machine body, a rotating plate is rotatably connected to one side of the fixed frame, a bolt is provided on one side of the rotating plate, a block is provided at one end of the bolt, a fixed strip is tightly fitted in the fixed frame, a first groove and a second groove are provided in the fixed strip, a movable plate is slidably connected in the second groove provided in the fixed strip, one end of the movable plate is fixedly connected to a fixed plate, a lead curtain is fixedly connected to the bottom of the fixed plate, holes are provided in the fixed plate and the movable plate, mounting columns are tightly fitted in the holes provided in the fixed plate and the movable plate, and a straight groove is provided on one side of the mounting column.

[0007] Preferably, the clamping block and the first groove opened in the fixing strip fit tightly together, and the bolts are formed into a group of two and penetrate the rotating plate.

[0008] Preferably, the fixing frames are arranged in groups of two at the left and right ends of the fixing strip, and two recesses are arranged on the inner side of the rotating plate.

[0009] Preferably, a handle is fixedly connected to the top of the movable plate, and one end of the handle is spherical.

[0010] Preferably, the fixing plate has an I-shaped cross section, and a plurality of fixing plates are arranged in front of the fixing strip.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] In the utility model, by providing the security inspection machine body, conveyor belt, base, fixing bar, second groove, fixing plate, moving plate, hole, mounting column, slot, lead curtain and handle, when the security inspection machine is in use, the lead curtain is worn due to frequent contact between the lead curtain and the luggage, and the severely worn lead curtain needs to be replaced. At this time, the slot on the surface of the mounting column is rotated with the help of a tool until it is taken out, and then the lead curtain is pulled upward by holding the handle until it is completely taken out for replacement. Since the cross section of the moving plate is arranged in an I-shape, and the second groove provided in the fixing bar and the cross section of the moving plate are closely fitted, the insertion is more stable and the removal is more convenient. The holes provided at the same position of the moving plate and the fixing plate facilitate the insertion of the mounting column and the fixing of the lead curtain. This device can replace a severely worn lead curtain separately.

[0013] By setting the fixing frame, rotating plate, bolts, blocks and first groove, when the lead curtain is severely worn as a whole and needs to be replaced, the operator turns the bolts to drive the blocks to move to the recessed part of the rotating plate, and then rotates the rotating plate to take out the fixing strip. By means of the device for individually and integrally disassembling the lead curtain, the lead curtain can be replaced individually or as a whole according to the wear of the lead curtain.

[0024] The first groove 9 opened in the clamping block 7 and the fixing strip 8 fits tightly, and the bolts 6 are grouped into two and penetrate the rotating plate 5 to facilitate the fixation of the fixing strip 8; the fixing frames 4 are grouped into two and are arranged at the left and right ends of the fixing strip 8, and there are two recesses on the inner side of the rotating plate 5 to facilitate the limiting of the fixing strip 8 by the clamping block 7; a handle 17 is fixedly connected to the top of the movable plate 12, and one end of the handle 17 is spherical to facilitate the pulling and pulling of the movable plate 12; the fixing plate 11 is I-shaped in cross section, and there are several fixing plates 11 arranged in front of the fixing strip 8 to facilitate the fixation of the lead curtain 16.

[0025] Working process: When the X-ray security inspection machine is in use, first place the main body 1 of the security inspection machine in a suitable position, and the user places the carry-on bag or other luggage on the surface of the conveyor belt 2. The conveyor belt 2 rotates to convey the luggage, passing through the lead curtain 16 until it reaches the inside of the main body 1 of the security inspection machine, and X-ray irradiation is used to determine whether there are prohibited items. Due to the frequent friction between the lead curtain 16 and the luggage, the bottom is easily worn. Due to the different sizes of luggage, the degree of wear of the lead curtain 16 is different. When one of the lead curtains 16 is severely worn due to long-term use and needs to be replaced, the operator uses a screwdriver to align one end with the slot 15 on the surface of the mounting column 14 above the lead curtain 16 to be replaced, and then rotates until the mounting column 14 is removed, and then holds the handle 17 to move it upward, driving the movable plate 12 to move between the fixed bars. 8 moves up, and at the same time drives the fixed plate 11 and the lead curtain 16 to move up until they are taken out. After replacing the new lead curtain 16, the movable plate 12 is inserted into the second groove 10 in the same way, and then the mounting column 14 is placed in the hole 13 opened in the movable plate 12 and the fixed plate 11, and the mounting column 14 is inserted as a whole using a screwdriver to complete a separate replacement of the lead curtain 16. When the lead curtain 16 is severely worn as a whole and needs to be replaced, the operator turns the bolt 6 to drive the block 7 to move to the recessed part of the rotating plate 5, and then rotates the two rotating plates 5 in opposite directions, takes out the fixing strip 8 to replace the lead curtain 16 as a whole. By means of a device for facilitating separate disassembly and assembly and overall disassembly provided on the lead curtain 16, the lead curtain 16 can be replaced individually or as a whole according to its wear condition.
