The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] This embodiment provides a bracket structure for installing a ray source group and a detector.

[0030] like Figure 1 to Figure 3 As shown, the support structure includes a support base 1 and a cover plate 2. The support base 1 includes a bearing plate 11 and a first mounting base 12 and a second mounting base 13 arranged on the bearing plate 11. The bearing plate 11 has a channel 111, so that the object to be measured can pass through the channel 111. The first mounting base 12 and the second mounting base 13 are arranged around the channel 111, and the first mounting base 12 and the second mounting base 13 are integrally formed, so that the first mounting base 12 and the second mounting base 13 can form a ring structure, and its overall structure is stable, the processing difficulty is low, and the manufacturing cost is reduced.

[0031] Among them, the first mounting base 12 is used to install the ray source group, and the second mounting base 13 is used to install the detector, and the relative position between the first mounting base 12 and the second mounting base 13 is fixed, thereby reducing the position error of the ray source group and the detector after installation. At the same time, during the rotation of the support base 1, the first mounting base 12 and the second mounting base 13 formed in one piece are not easy to deform, thereby ensuring the scanning detection accuracy. The cover plate 2 is detachably connected to the second mounting base 13 and is used to crimp the detector, further reducing the difficulty of installing the detector, and by using the cover plate 2 instead of the box body, the weight of the bracket structure can also be reduced. Optionally, a weight reduction groove 14 is provided on the first mounting base 12 and / or the second mounting base 13, so that the weight of the bracket structure can be further reduced by setting the weight reduction groove 14, which facilitates the installation of the bracket structure in the CT scanning device.

[0032] Specifically, in this bracket structure, since the cover plate 2 and the second mounting base 13 are detachably connected, the staff can first machine the support base 1 and the cover plate 2 separately, and then install the cover plate 2 on the support base 1 and then machine the whole, so as to improve the processing accuracy.

[0033] like Figure 2 As shown, the first mounting base 12 has a first mounting surface 121, a second mounting surface 122 and a third mounting surface 123, and the first mounting surface 121, the second mounting surface 122 and the third mounting surface 123 are arranged on the side away from the channel 111, and the ray source group includes a ray source body, an electrical assembly and a cooling assembly, and the ray source body is arranged on the first mounting surface 121, the electrical assembly is arranged on the second mounting surface 122, and the cooling assembly is arranged on the third mounting surface 123, so that through the arrangement of the three mounting surfaces, the ray source body, the electrical assembly and the cooling assembly can be installed respectively, so as to reasonably utilize the space between the bearing plate 11 and the first mounting base 12, and reduce the difficulty of installing the ray source group. Specifically, the second mounting surface 122 and the third mounting surface 123 are located on both sides of the first mounting surface 121, and the first mounting surface 121 is arranged at an angle with the second mounting surface 122 and the third mounting surface 123, so that the ray source body, the electrical assembly and the cooling assembly are all oriented in different directions, so as to prevent interference between the three.

[0034] like Figure 1 and Figure 2As shown, the second mounting base 13 includes a mounting platform 131 and a connecting platform 132. The mounting platform 131 and the first mounting base 12 are arranged opposite to each other. The connecting platform 132 is located between the mounting platform 131 and the first mounting base 12. The connecting platform 132 is detachably connected to the cover plate 2. The mounting platform 131 is used to install the detector, so that the connecting platform 132 can separate the mounting platform 131 from the first mounting base 12 to facilitate the arrangement of the ray source group and the detector. Among them, the distance between the mounting platform 131 and the bearing plate 11 is smaller than the distance between the first mounting base 12 and the bearing plate 11, so that a space can be reserved between the cover plate 2 and the mounting platform 131 for the outgoing rays to pass. Specifically, the cover plate 2 and the second mounting base 13 can be aligned by a positioning pin and then connected by a bolt. Optionally, a mounting hole 21 is provided on the cover plate 2, and the mounting hole 21 is used to install a cooling fan, so as to facilitate the gas replacement circulation heat dissipation of the bracket structure.

[0035] like Figure 1 and Figure 3 As shown, the side of the carrier plate 11 away from the first mounting base 12 is provided with an annular reinforcing rib 112 and a rib plate 113 connected to each other, the annular reinforcing rib 112 and the channel 111 are coaxially arranged, and a plurality of rib plates 113 are provided, and the plurality of rib plates 113 are arranged around the annular reinforcing rib 112, so as to enhance the overall rigidity of the support base 1 and prevent the support base 1 from deforming and affecting the scanning detection. Optionally, the side of the cover plate 2 away from the support base 1 is provided with a plurality of staggered reinforcing ribs, so as to enhance the overall rigidity of the cover plate 2.

[0036] Furthermore, the support structure further comprises a connecting rod, two ends of which are respectively connected to the bearing plate 11 and the cover plate 2 , so as to enhance the overall structural strength of the support structure.

[0037] This embodiment also provides a CT scanning device, including the support structure as described above, the CT scanning device also includes a carrier frame, and the carrier plate 11 is rotatably arranged on the carrier frame. Therefore, the CT scanning device reduces the position error of the ray source group and the detector after installation by using the support structure as described above, and prevents the deformation of the support structure so as to change the relative position of the ray source group and the detector, thereby ensuring the scanning detection accuracy and improving the imaging quality of the system.

[0038] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
