This method has the following disadvantages: 1. The position and angle positioning is not accurate, and it cannot be adjusted continuously within the channel range, and it is difficult to obtain the best test body image; 2. It is difficult and time-consuming to adjust the position and angle. For a certain position Local adjustments often take a long time to locate, and the adjusted angle is difficult to record and reproduce. It takes about 6 hours to complete the performance index test of a piece of equipment on average; 3. The test device is simple and the safety is poor. Repeatedly entering and exiting the entrance of the cargo X-ray safety inspection equipment, the test body is located at a higher position, and it is easy to change its position or even fall over when passing through the lead curtain

Embodiment Construction
[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0021] Such as figure 1 As shown, the structure of the test device for testing freight X-ray security inspection equipment of the present invention mainly includes: a base, a lift, a first test body mounting seat, a second test body mounting seat, and a control unit.
[0022] Such as figure 2 , wherein the base 1 is composed of four substrates of the same size, and the substrates are positioned and connected by a number of fixing strips 2. The hinge 27 is used to connect the upper and lower parts of the substrate, and allows the base to be folded and stored in a non-use state. The control box The positioning magnet 6 is installed on the edge of a substrate of the base, and is used for positioning the control box during the test. Four sets of L-shaped fixed limit seats 4 are respectively connected to the elevator and the base 1 thro...

Description
technical field [0001] The invention relates to the testing field of security inspection equipment, and more particularly, relates to a testing device for testing cargo X-ray security inspection equipment. Background technique [0002] Cargo X-ray security inspection equipment is widely used in airports, railways, freight stations and other public places. This type of equipment uses the principle of X-ray transmission to image the inspected items, and the security inspectors judge the shape and material of the inspected items based on the images. The application of such equipment can effectively prevent the transportation of contraband and dangerous goods, and is an important means of ensuring safety. [0003] For the field of security inspection, it is necessary to accurately identify each item in the checked item according to the shape and material of the checked item. According to the national standard GB15208.1-2005 "Micro-dose X-ray Inspection Equipment Part 1: Genera...
