The X-ray source protection component 3 can be adjusted up and down along the Z-axis direction on the Z-axis mounting plate 4.

[0029] Among them, the multifunctional detection desktop component 1 includes a cone-beam CT desktop detection mechanism, and the X-ray source protection component 3 includes a first limit plate 5, a second limit plate 6 and a positioning plate 7 arranged between the first limit plate 5 and the second limit plate 6.

[0030] Embodiment 2

[0031] This embodiment provides an X-ray source protection device for an X-ray detection device, such as Figure 6-7 As shown, its structure is basically the same as that of the first embodiment, except that the multifunctional detection desktop assembly 1 includes a planar CT desktop detection mechanism.

[0032] The working principle of the X-ray source protection device of the utility model for X-ray detection equipment is as follows:

[0033] When there is a need for planar CT inspection (there is carbon fiber on the planar CT inspection table), the position of the X-ray source protection assembly 3 is adjusted until the indexing pin 12 is inserted into the bottom positioning hole of the adjustment plate 11 for inspection;

[0034] When cone beam CT inspection is required (X-ray source and product are kept at the minimum distance), the position of X-ray source protection assembly 3 is adjusted until indexing pin 12 is inserted into the middle positioning hole of adjustment plate 11. At this time, the position of X-ray source protection assembly 3 is slightly higher than the light-emitting surface of X-ray source assembly 2. At this time, adjusting the height of the table can ensure that the distance between the ray source and the inspected product is the closest and protect the X-ray source assembly 2. The specific position relationship diagram during inspection is shown in the figure below. Figure 5 As shown, a is the product to be tested, b is the sensing position of the sensor, and c is the surface of the radiation source;

[0035] When the X-ray source assembly 2 needs to be moved out, it is only necessary to adjust the position of the X-ray source protection assembly 3 until the indexing pin 12 is inserted into the positioning hole at the highest position of the adjustment plate 11. At this time, the X-ray source assembly 2 will not be affected by the X-ray source protection assembly 3 and can be moved directly.

[0036] To sum up, the X-ray source protection device of the X-ray detection equipment provided by the utility model can meet the X-ray source protection requirements for different detection needs, has the advantages of simple structure, stability and reliability, low production cost and easy installation and maintenance, has great market value, and deserves wide promotion and application.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
